Description
FIELD OF THE INVENTION
[0001] The present invention is concerned with tissue paper
dispensing systems, packaging for tissue paper sheets and
interfolding arrangements for tissue paper sheets. The present
invention is concerned with absorbent tissue paper sheets of all
kinds, including toilet tissue paper sheets/hygiene paper
sheets/non-woven absorbent sheets, facial tissue paper sheets,
kitchen paper towel type tissue paper sheets, hand towel type paper
sheets, paper napkins, moist wipes, etc.
BACKGROUND TO THE INVENTION
[0002] Various types of tissue paper packages are known in the art.
There is toilet tissue paper, which is generally provided as a roll
of tissue paper. The toilet tissue paper is in the form of a
continuous web of tissue paper divided into sheets, each about the
length of a hand (but smaller and larger sheets are also known), by
a perforation line across the web. The web of toilet tissue paper
is wrapped about a tubular core. Kitchen tissue paper for wiping up
kitchen spills is often also provided in the form of a roll of
tissue. It is also known to provide toilet tissue paper as a stack,
rather than as a roll. The sheets of toilet paper are interfolded
so that as one sheet is pulled out, the next sheet comes with it to
protrude partly through a dispensing opening of a holding wall
mounted dispenser holding the stack. The stack may be wrapped in a
thin paper that has to be removed before the dispenser is loaded.
Coreless toilet tissue paper stacks are also known, which are
discussed below.
[0003] There is also known facial tissue paper, which may be
provided as a stack of interfolded tissue paper sheets. A box
containing the tissue paper stack has a dispensing opening through
which the facial tissue paper sheets can be withdrawn, one-by-one.
Interfolding the tissue paper sheets allows the withdrawal of a
succeeding sheet to partly pull out a preceding sheet. A partly
pulled out sheet thus sticks out from the dispensing opening for
ease of grabbing and withdrawing. The box is disposable in that it
is made of biodegradable materials such as cardboard.
[0004] The present inventors have noted a flaw in a tissue roll
design in terms of hygiene. A roll of tissue paper generally has to
be handled by both hands in separating a sheet or sheets from a
roll. This means that a prior user has handled the tissue that a
next user uses. From a hygiene perspective, this is sub-optimal,
especially in the context of toilet tissue paper. There is also a
problem in that rolls of tissue paper can not be transported and
stored in a perfect stack. That is, the tubular core of the roll
and poorly nested rolls mean that space is wasted that could
otherwise be taken up by tissue paper.
[0005] Facial tissue paper boxes and toilet tissue paper stacks are
in some ways a more hygienic option than tissue paper rolls. The
boxes provide a relatively closed structure, whereby access is only
given to the uppermost sheet in the stack in the box, which is the
sheet that the user uses him/her-self. There is, however, room for
improvement in present tissue paper packages. They are normally
designed so that a cut-out formed by perforations is torn away to
reveal the dispensing opening. A more intuitive, less fiddly way to
open a tissue paper package is desirable. Also, dispensing tissue
from a conventional tissue paper box is usually a two handed
process. One hand holding the box down and the other hand pulling a
tissue paper sheet out. One handed tissue paper dispensing is
preferable.
[0006] A stack of toilet tissue paper sheets may be provided for
dispensing from a permanent dispenser. Refill packs of toilet
tissue paper sheets are provided to fill the dispenser. Paper towel
dispensers are also known in the art. Such towels may be designed
for hand or face drying. These can be provided in the form of wall
mountable containers that are loaded with a stack of paper towels
or toilet tissue paper sheets. To load, the paper towels or toilet
tissue paper sheets are removed from a wrapping, which may be
plastic or paper, and loaded into the container. One design of a
container for paper towels has, at a bottom end, a slit aligned
with a longitudinal axis of the paper towels so that the towels can
be withdrawn from the container, one at a time. The container and
paper towel stack are commonly configured such that a paper towel
is tugged in a direction of a transverse axis of the paper towel to
pull it from the container. The present inventors have noted that
the short axis of the paper towel is thus presented to the user,
which often then gets rotated so that a long axis of the towel is
aligned with a long axis of the face. One design of the toilet
tissue dispenser and stack of toilet paper tissue has interfolded
sheets so that as a sheet is withdrawn from the dispenser, it
partially pulls the next sheet to be dispensed with it through the
slit for ease of grasping the next sheet. Interfolded toilet tissue
dispensers have not taken off in the domestic context, although
they are used in business or away from home environments. One
reason for this is perhaps because the bulk of toilet tissue
dispensers make them unsuitable for domestic use. Perhaps another
reason for this is that the dispensers are not easy to load.
Another reason for it may be that the present designs of the
dispenser do not fit with what people expect or want in a domestic
environment.
[0007] As with the stack form toilet tissue paper dispenser
mentioned above, it should be apparent that improvements can be
made to make the loading and use process of the container or
dispenser closer to a one-step operation. Likewise, the tissue
loading and dispensing process could be more ergonomically
friendly.
[0008] Accordingly, it is an object of the present invention in,
its various aspects, and preferred embodiments to address the above
issues and provide improved tissue paper systems.
SUMMARY OF THE INVENTION
[0009] In one aspect of the present invention, there is provided a
package comprising a stack of absorbent tissue paper sheets,
wherein the package comprises at least one line of weakness that
has an unbroken configuration and a broken configuration and
wherein the package is configured to be able to be flexed to pull
apart the line of weakness when the line of weakness is in the
broken configuration to open the package to allow a sheet in the
stack to be withdrawn through the open package.
[0010] Preferably, the stack of tissues is elongate and the opened
package reveals a longitudinally central region of the stack of
tissues, while the longitudinal ends of the stack remain covered by
the package. Preferably, the package and the line of weakness are
configured so that the line of weakness is broken by flexing the
package.
[0011] A package so designed provides an intuitive, even
satisfying, way of opening it to get at the sheets. For a package
to be configured in this way, it needs be able to be flexed without
strain for most adults, including the elderly and young adults.
There is a certain feeling of gratification in cracking open a
package in this way.
[0012] In an alternative embodiment, the line of weakness defines,
at least partly, a tear away strip that is configured to be pulled
in a direction of extension of the line of weakness to break the
line of weakness. The tear off strip could be implemented by way of
a pair of spaced apart lines of weakness with a protrudable pull
tab at one end of the tear off strip, whereby the pull tab is
pullable in the direction of extension of the pair of lines of
weakness to break the at least one line of weakness so that the
package can be opened.
[0013] Preferably, the package is sized so as to be grasped by the
full hands of a user in order for the flexure to be carried out.
That is, the package is sized so that the palm (at least partly),
the fingers and the thumb of one hand fit about the package (such
that the package fills the hand) on one side of the line of
weakness and the palm, the fingers and the thumb of the other hand
fit about the package on the other side of the line of weakness
(such that the package fills the hand). The hands can be
manipulated so as to flex the package and thereby break open the
line of weakness. The package is sized so as to be suitable for
being opened in the manner. In practice, a user may prefer to apply
the counter rotational forces using one hand at one side of the
line of weakness and using a work surface, for example, as a
counter resistance. Other single-handed ways of breaking the line
of weakness can be imagined by the skilled person.
[0014] Preferably, the package is elongate. The at least one line
of weakness may be placed in a central region and extend across the
longitude of the package. The at least one line of weakness may, in
fact, be at least one lateral line that is centrally positioned
with respect to a longitudinal direction of the package. Opposing
longitudinal end regions of the package can thus be grasped and a
turning force can be applied by the user about a pivot point
provided by the line of weakness. In this way, the line of weakness
is provided at an optimal line of pivot about which the package can
be flexed to reduce the force required to open the package. If the
line of weakness was longitudinally extending, then opposing
lateral sides of the line of weakness would need to be grasped,
which would make it harder to create the required flexure because
of the increased turning force.
[0015] Preferably, the package is configured to be flexed about a
hinge portion of the package, which serves to keep the package
together when the line of weakness has been broken open. That is,
the line of weakness may extend about the package such that a hinge
portion of the package remains when the line of weakness is broken
open. The line of weakness may encompass three of four sides (other
than end faces of the package) about the package, with at least
part of the fourth side serving as the hinge portion of the
package. Put another way, the line of weakness extends about a
majority of a lateral periphery of the elongate package so that the
minor part of the package that is not encompassed by the line of
weakness serves as a hinge portion keeping opposing parts of the
package together and allowing the package to open about the hinge
portion.
[0016] The package is preferably openable about a hinge portion on
one face of the package to provide a dispensing opening on an
opposing face of the package.
[0017] Preferably, the package is configured to be flexed from a
closed and sealed configuration to an opened configuration in
breaking the line of weakness. Preferably, the package can be
manipulated back to its closed configuration, whereby opposing
sides of the broken line of weakness are in contact. This
manipulation is preferably done by rotating the package about the
hinge portion.
[0018] The package is preferably stiff enough to maintain the open
configuration even when the package is oriented so that the weight
of the tissues presses against the hinge portion. Such an
embodiment enables the package to serve as a counter top tissue
paper dispenser. Put another way, the package is stiff enough that
when empty it at least substantially retains the shape it has when
it is full. The package may be made of cardboard, paper or plastic.
Preferably, the package is made of a biodegradable material.
[0019] In a second aspect of the present invention, there is
provided a package comprising a stack of absorbent tissue paper
sheets, wherein the package is openable, from a closed
configuration concealing the tissues, by moving one part of the
package relative to another part of the package, and wherein a
cover is moveable with one of the parts relative to the other part
so as to cover a portion of the sheets, yet leave uncovered a
portion of the sheets to thereby allow a sheet to be withdrawn from
the package.
[0020] Preferably, the first aspect of the invention and the second
aspect of the invention are combined, whereby the package is
configured such that respective parts of the package move apart
from one another when the line of weakness is broken and the
package is opened and a cover is provided to move with one of the
parts relative to the other to cover a portion of the sheets when
the package is in an opened configuration and to leave a portion of
the sheets uncovered to allow access to the tissues to withdraw a
sheet from the package.
[0021] A stack of sheets can be described as having a top sheet
providing a top of the stack, a bottom sheet providing a bottom of
the stack and a number of sheets stacked between the top and bottom
sheets providing sides of the stack connecting the top and bottom
of the stack. The cover is preferably configured to cover a side of
the stack of sheets when the package is in the opened
configuration.
[0022] Preferably, the cover is see-through enough to reveal when
the number of sheets left in the stack has reached a depleted
state. That is, once there are less than a predetermined number of
sheets left in the stack, the user can see this depleted state
through the cover by observing the position of the last sheet in
the stack.
[0023] Preferably, the cover is combined with the embodiment
described above whereby the package has a hinge portion and the
package is openable and closable by rotation about the hinge
portion. Rotation of the package about the hinge is such as to
provide a dispensing opening in the package through which a first
sheet in the stack (closest to the dispensing opening in a sheet
withdrawal sequence of the stack) is revealed and can be withdrawn,
where the top sheet is on an opposing side of the stack to the
hinge, and also to provide a side opening through which the stack
is revealed in a thickness direction (or stacking direction). The
side opening becomes more spread apart from the hinge end to the
dispensing opening end. Preferably, the cover is configured to
cover the side opening. Preferably, the cover is substantially
correspondingly shaped to the side opening. Yet more preferably,
the side opening is a triangle shape, with an apex thereof
extending to the hinge portion. A base of the triangle at the
dispensing opening may be curved or straight.
[0024] Preferably, in the closed configuration, preferably the
closed configuration with the line of weakness as yet unbroken, the
cover is inside the package. Preferably, the cover is attached to
one side of the line of weakness, preferably an inside surface of a
wall of the package on one side of the line of weakness, and
extends to the other side of the line of weakness in a cantilevered
fashion.
[0025] Preferably, the cover is attached to one part of the package
and is configured to slide with respect the other part of the
package as the parts move relative to one another in opening the
package. That is, in the closed configuration of the package, the
cover overlaps with the other part of the package and moves into a
less or non-overlapping state as the package opens.
[0026] In a third aspect of the invention, there is provided a
container for containing a stack of interfolded absorbent tissue
paper sheets, the container comprises a dispensing opening for
withdrawing a sheet of the stack through the dispensing opening,
wherein the dispensing opening has overlapping lips in a direction
of withdrawal of the sheet, the lips configured to be opened into a
less overlapping or non-overlapping state as the sheet moves
therethrough and to return to an overlapping state after withdrawal
of the sheet.
[0027] The container may comprise the stack of sheets. The
container may be a package comprising a stack of sheets, preferably
as defined in the foregoing. The container is able to resist
tissues undesirably falling out of the dispensing opening when they
are not being withdrawn. In particular, the container may be
mounted so that the weight of the stack is directed to the
dispensing opening. Despite the weight pressing on the opening, the
lips are able to prevent the sheets slipping out of the dispensing
opening. This is because the lips have to be quite substantially
deflected from an overlapping state in order for any tissues to
pass. This is to be compared to known dispensing opening in tissue
paper boxes, whereby a film is spread across the dispensing opening
and has a slit in it. Although the slit does have a tendency to
resist sheets slipping out of the dispensing opening
unintentionally, it does not require as great an amount of
deflection as overlapping lips as in the third aspect of the
present invention.
[0028] In the tissue withdrawal direction, one of the lips is more
forward than the other. Preferably, the lips are configured such
that they alternate which of the lips is the more forward lip for
each sheet that is dispensed.
[0029] Preferably, the overlapping lips are shaped to provide an
opening through which a sheet adjacent the dispensing opening can
be grasped without having to move the lips. That is, the opening
provides a direct path for a user's fingers to the sheets, which is
useful when first loading the sheets to pull a first sheet through
the lips and the dispensing opening. Preferably, the dispensing
opening is elongate and the opening is centrally located between
opposing longitudinal ends of the dispensing opening. Preferably,
the lips are shaped to provide the opening, whereby the sheet is
able to be drawn therethrough free from contact from the
overlapping lips on opposing faces of the tissue and whereby on
opposing sides of the opening in a direction perpendicular to the
sheet withdrawal direction along a face of the tissue, the
overlapping lips contact opposing faces of the sheet as it is
pulled therethrough. Preferably, the dispensing opening is elongate
and the overlapping lips are configured to contact opposing faces
of the tissue as it is pulled therethrough and are located at
opposing longitudinal end portions of the dispensing opening and
the opening defined by the overlapping lips is centrally located
between the opposing longitudinal end portions.
[0030] The sheet withdrawal direction is used frequently in this
specification. It is a direction normal to the plane of the sheets
in the stack. It passes centrally through the dispensing opening of
a package, container or dispenser. The dispensing opening is
defined by terminating walls about its periphery. The plane in
which these walls terminate provides another plane to which the
tissue withdrawal direction extends normally.
[0031] In the case of a package comprising a stack of absorbent
tissue paper sheets, the sheets in the stack are interfolded and
the package comprises a dispensing opening so that as a succeeding
sheet is withdrawn from the package through the dispensing opening,
a preceding sheet is partially pulled out with it and so that once
the succeeding sheet is fully withdrawn through the dispensing
opening, the succeeding sheet parts with the preceding sheet, which
sticks out from the dispensing opening, yet remains as a leading
sheet in the stack.
[0032] Preferably, the sheets are interfolded in an interfolding
pattern whereby each sheet is folded at least once so as to
comprise a leading panel and a trailing panel, and whereby for any
given sheet in the stack, the leading and trailing panels have a
trailing panel of a next sheet and a leading panel of a previous
sheet disposed between panels of the given tissue in face to face
relation.
[0033] Preferably, the interfolding pattern of the stack of sheets
and the overlapping lips are configured such that as a leading
panel of a sheet closest to the dispensing opening is pulled upon
to withdraw the sheet, the leading panel moves through the
dispensing opening and the overlapping lips, thereby deforming the
lips in a withdrawal direction, and further wherein as the leading
panel is pulled, a trailing panel is in face to face relation with
a leading panel of an adjacent sheet preceding in the stack so that
it pulls the leading panel of the preceding sheet through the
overlapping lips and the dispensing opening with it, and wherein
once a trailing edge of the trailing panel of the succeeding sheet
is released by the overlapping lips, and is thereby out of the
dispending opening, the succeeding sheet is released and the
leading panel of the preceding sheet protrudes past the overlapping
lips for being pulled upon to withdraw the next sheet through the
dispensing opening.
[0034] The overlapping lips and the interfolding pattern of the
stack of tissue paper sheets are preferably configured such that a
first one of the lips is more distal to the stack of sheets than a
second one of the lips and such that as a sheet is pulled through
the dispensing opening and through the overlapping lips, the
overlapping lips deform in the withdrawing direction, and the first
sheet is in partial face to face relation with a preceding sheet in
the stack so that it pulls the preceding sheet with it, and wherein
the preceding sheet comes out adjacent the second one of the lips
with the succeeding sheet disposed between the preceding sheet and
the first one of the lips, and such that as a trailing edge of the
succeeding sheet is pulled beyond the overlapping lips, the
succeeding sheet is released from the container and the first one
of the lips resiliently drops back in the withdrawing direction so
as to be behind the second one of the lips.
[0035] Thus, the interfolding pattern is such that the tissues are
dispensed in an alternating manner between first and second sheet
withdrawal configurations. In the first sheet withdrawal
configuration, a succeeding sheet is located adjacent a first one
of the overlapping lips as compared to a preceding sheet that is
pulled through the lips with it, as a result of tissue face to
tissue face contact, which is located adjacent a second one of the
lips (in the sheet withdrawing direction). In the second sheet
withdrawal configuration, the succeeding sheet is located adjacent
the second lip and the preceding sheet is located adjacent the
first lip. Alternation between the sheet withdrawal configurations
between each successively withdrawn sheet results in the
overlapping lips alternating between first and second lip
configurations. The first lip configuration has the first lip more
forward in the sheet withdrawal direction than the second lip and
occurs as a result of a sheet being withdrawn under the second
sheet withdrawal configuration. The second lip configurations has
the second lip more forward in the sheet withdrawal direction than
the first lip and occurs as a result of a sheet being withdrawn
under the first sheet withdrawal configuration.
[0036] In a fourth aspect of the present invention, there is
provided a dispenser for holding a stack of absorbent tissue paper
sheets or a package comprising a stack of absorbent tissue paper
sheets, wherein the dispenser defines a dispensing opening and a
cavity for receiving said stack or said package, wherein the
dispenser defines the cavity to follow a path including a v shape
whereby an outside edge of a peak of the v shape extends into the
dispensing opening such that when the stack or package is inserted
into the cavity, and the stack or package is sized to fill the
cavity, it must be deformed to have the v or u shape to fit
therein.
[0037] The fourth aspect of the present invention aims the stack
toward the dispensing opening and requires the stack to be deformed
into a bent v shape. This provides a bias so that the sheets
protrude from the dispensing opening for convenient tissue sheet
withdrawal. An outside edge of a v shape is to be understood in the
context of the legs of the v shape defining a relatively narrow
angle between them on an inside and defining a relatively large
angle between them on an outside. The v shape may be curved at its
peak, rather than pointed.
[0038] Looked at in another way, the fourth aspect of the present
invention provides a dispenser for holding a stack of absorbent
tissue paper sheets or for holding a package comprising a stack of
absorbent tissue paper sheets, wherein the dispenser comprises
first and second walls, the first wall being made at least partly
up of first and second wall parts that are angled toward one
another to define a point of intersection and the second wall being
made at least partly up of first and second wall parts that are
angled toward one another in the same way as the first wall part
but to define a dispensing opening therebetween where the point of
intersection is positioned in the first wall part, the dispensing
opening allowing sheets from the stack to be withdrawn, the first
and second walls being spaced apart to provide a stack receiving
cavity therebetween, wherein a line bisecting the angle between the
first and second wall parts of the first and second walls passes
through the point of intersection of the first wall and the
dispensing opening of second wall.
[0039] Preferably, a first line bisecting the angle between the
first and second parts of the first and second walls extends
through the point of intersection of the first wall and the
dispensing opening defined by the second wall. Preferably, a line
perpendicular to the first line will pass through a first point on
the second wall and a second point on the second wall (preferably
equally spaced from the dispensing opening). The point of
intersection and the first and second points thus provide a three
point load tending to fold or flex the stack toward the dispensing
opening.
[0040] Preferably, the first and second walls are shaped and spaced
apart to define a v shaped cavity therebetween such that when the
stack or at least one package is inserted into the cavity it must
be shaped to have the v shape to fit therein.
[0041] It is envisaged that the package of tissue paper sheets and
the cavity may be sized such that the package fills the cavity. It
is also envisaged that the cavity may be oversized so that a
partially depleted and a full package fills the cavity or so that a
plurality, e.g. two packages may be required to fill the cavity. In
this way, the dispenser can be tapped-up without requiring the
current package being used dispensing to first be removed.
[0042] Preferably, the dispenser includes opposed top and bottom
walls defining a thickness of the v shape of the cavity between
them, wherein one of the walls defines an inside edge of the v
shape and provides an inside peak of the v shape and the other of
the opposing walls defines an outside edge of the v shape of the
cavity and defines the dispensing opening located where an outside
edge of the peak of v shape would otherwise be. The thickness of
the v shape of the cavity determines the number of tissues in the
stack that can be received therein.
[0043] Preferably, the dispenser includes opposed sidewalls
extending between the top and bottom walls to together define a
periphery of the cavity.
[0044] Preferably, the dispenser defines legs of the v shape of the
cavity to have an angle of between 170.degree. and 100.degree.,
160.degree. and 110.degree. or 120.degree. or 130.degree. or
140.degree. and is preferably about 150.degree.. It has been found
that angles such as these are optimal for providing a bias for the
sheet to protrude through the dispensing opening, without being so
steep as to cause the tissue to unintentionally fall through the
dispensing opening under the weight of gravity (particularly as the
tissue stack becomes depleted).
[0045] Preferably, the dispenser defines the cavity to be elongate
for receiving an elongate stack of tissue paper sheets or elongate
package comprising a stack of tissue paper sheets, to have a
thickness direction with which the stacking direction of the stack
of tissue paper sheets is to be aligned and a lateral direction
across a face of the stack of tissue paper sheets. The dispenser
defines the peak of the v shape of the cavity at a central location
between opposed longitudinal ends of the cavity so as to require,
when the stack of sheets is sized to fill the cavity in the sheet
stacking direction, the stack of sheets to have a bend line in a
lateral direction across a face of the stack and centrally located
between opposed longitudinal ends of the stack.
[0046] Preferably, the dispenser defines an elongate cavity for
receiving an elongate stack of sheets or an elongate package
comprising a stack of tissue paper sheets, wherein the dispenser is
open at a front face for loading the stack or package therethrough
into the cavity, wherein the dispensing opening and the cavity are
oriented so that there are a sheet withdrawal direction and a
longitudinal direction of the cavity that are perpendicular to one
another and perpendicular to both of these directions is a front
back direction.
[0047] Preferably, the dispenser includes the first and second
walls defining top and bottom faces of the cavity in a sheet
withdrawal direction, which is also in the direction of a first
line bisecting the angle between the first and second parts of the
first and second walls. The dispenser includes end walls defining
end faces of the cavity in a longitudinal direction of the cavity,
which is a straight line extending through corresponding points in
the sheet withdrawal direction on the end walls. In a front to back
direction perpendicular to the longitudinal direction and the
tissue withdrawal direction, there are a rear wall defining a rear
face of the dispenser and an open front face of the cavity for
loading purposes.
[0048] Preferably, the dispenser includes an opening or recess for
wall mounting the dispenser by way of a wall fastener. Preferably,
the dispenser includes a removable wall fastener that is to be
fastened to a room wall and a recess for receiving the wall
fastener, where edges of the wall fastener and the recess cooperate
to attach the dispenser to its wall fastener, and wherein of the
edges is bifurcated so that the other edge can be received in the
bifurcation in a sliding manner.
[0049] In a fifth aspect of the present invention, there is
provided a system of a dispenser and a package comprising a stack
of absorbent tissue paper sheets as described above with respect to
the first to fourth aspects of the present invention. The dispenser
has a housing defining a cavity for receiving the package and a
dispensing opening, wherein the housing defines the cavity so as to
hold the package in an opened configuration, wherein the package is
in its flexed form and the dispensing opening of the package is
aligned with the dispensing opening of the dispenser so that a user
can withdraw a sheet from the stack through the dispensing
openings.
[0050] Preferably, the dispensing opening of the package opens
about a hinge portion of the package and the dispenser holds the
package open in a configuration such that the dispensing opening
transverses from 10.degree. to 80.degree. about the hinge portion,
15.degree. to 70.degree., 20.degree. to 60.degree., 25.degree. to
50.degree. or 40.degree., 25.degree. to 35.degree. and preferably
about 30.degree.. When the dispensing opening of the package is in
the closed configuration, the package is 0.degree. open about the
hinge portion. If the opening angle is too great, interfolding of
sheets in the stack could come undone.
[0051] Preferably, the package has a hinge portion as described
above and the dispenser housing defines a path of the cavity to
include a v shape such that the hinge portion of the package is
located at a peak of an inside edge of the v shape of the cavity.
Preferably, the dispensing opening of the dispenser is located at a
position where an outside edge of a peak of the v shape of the
cavity would otherwise have been. Preferably, the dispenser is as
described above with respect to the fifth aspect of the present
invention. The package of sheets is preferably a refill package of
sheets and the cavity is for being loaded with the refill
package.
[0052] In a sixth aspect of the present invention, there is
provided a stack of interfolded absorbent tissue paper sheets. The
interfolding pattern is such that each sheet is folded at least
once to provide leading and trailing panels with respect to a
tissue withdrawal direction in the stacking direction. The
interfolding pattern is such that for any given tissue in the
stack, a trailing panel of an adjacent tissue subsequent in the
stack in the tissue withdrawal direction is in face to face,
overlapping relation with a leading panel of the given sheet and a
leading panel of an adjacent sheet preceding in the stack in the
sheet withdrawal direction is in face to face, overlapping relation
with the trailing panel of the given sheet, such that the trailing
panel of the subsequent sheet and the leading panel of the
preceding sheet are disposed between panels of the given sheet,
wherein the overlap of the given sheet with the trailing panel of
the subsequent sheet and the leading panel of the preceding sheet
is a partial overlap to provide an overlapping region of the given
sheet where the leading and trailing panels of the given sheet
overlap with the leading panel of the preceding sheet and the
trailing panel of the subsequent sheet and a non-overlapping region
of the given sheet wherein the leading and trailing panels of the
sheet extend beyond the overlapping faces to a fold portion,
thereby to define a stack comprising an overlapping region where
adjacent sheets in the stack overlap and non-overlapping regions of
the stack on opposed sides of the overlapping region wherein
adjacent sheets of the stack do not overlap.
[0053] The overlapping and non-overlapping regions of the stack
elongate the stack in a first direction of the stack from the
non-overlapping region to the overlapping region and to the
non-overlapping region, wherein the first direction is
perpendicular to the sheet withdrawal direction. This elongation
may be desirable in certain stack applications and is achieved by
the interfolding arrangement. Further, the weight of the stack is
biased in the overlapping region, which may provide improved
dispensing when the overlapping region is aligned with a dispensing
opening of a dispenser or a stack package.
[0054] The sheets may include n multiple folds, such as the forward
most panel and the rearward most panel of the sheet in the sheet
withdrawing direction that are respectively the leading and
trailing panels. Preferably, however, the sheets are single fold,
two panel sheets.
[0055] Preferably, a ratio of length of the overlapping region of
the stack in the first direction to a length of the stack in the
first direction (which is an inverse ratio of length of
non-overlapping regions to a length of the stack) is in the range
of 0.10 to 0.90, 0.15 to 0.75, 0.2 to 0.6 and most preferably in
the range of 0.25 to 0.50. These ranges provide sufficient overlap
of the sheets for the withdrawal of a sheet to pull the preceding
tissue out from the stack by way of the face to face interaction of
the sheets, while the overlap is not so great as to nullify the
elongation and weight centring effects. The greater the degree of
overlap, the less air there is in the package, which is largely
contained in the non-overlapping portion.
[0056] Preferably, the sheets are elongate and the overlapping
region extends laterally across the sheets from one lateral side of
the sheet to the other. Preferably, the leading panel and the
trailing panel are connected by a fold line. Preferably, the tissue
is elongate and the fold line extends laterally across the
tissue.
[0057] The panels of any given sheet in the stack may be connected
by a fold line. The panels may be connected by a line of
perforations or other line of weakness to allow a panel to be torn
off from its adjacent panel. The sheets may be folded at the line
of weakness so that the fold line constitutes the line of
weakness.
[0058] In a preferred embodiment, the stack of sheets is provided
as a package of sheets as defined above with respect to the first
to sixth aspects of the present invention. The stack of sheets may
also be provided in a container or a dispenser as described above
with respect to the third and fourth aspects of the present
invention.
[0059] The combination of the stack of sheets defined according to
the sixth aspect of the invention and the package comprising a
stack of sheets and overlapping lips for a dispensing opening
according to the third aspect of the invention provides a
functional complex that can be particularly useful. The overlapping
region tends to weigh down on the dispensing opening of the package
if oriented so that gravity is aligned with the withdrawal
direction of the tissues. The overlapping lips are thus
particularly important for avoiding the tissues falling through the
dispensing opening.
[0060] In a generally applicable feature, the package or dispenser
preferably has a dispensing opening that is substantially the same
width or greater than the sheets, with respect to a direction along
the face of the sheets perpendicular to the withdrawal direction,
such that as a sheet is pulled out from the stack through the
dispensing opening and optionally also the overlapping lips,
opposing sides edges, in the width direction, of the sheet are able
to maintain their lateral spacing. In the prior art, dispensing
openings, particularly lips for holding tissue in a protruded state
from a tissue box, tend to crumple the tissue width-wise into a
more snake like configuration. The overlapping lips are configured
so that a passage between them is sized so as to enable a sheet to
pass through them with lateral constriction. An advantage of a roll
of tissue is that it does not have to be so crumpled to dispense
it. The package or dispenser of the present invention is able to
provide a stack of sheets that does not crumple upon
dispensing.
[0061] In a seventh aspect of the present invention, there is
provided a moist sheet or tissue paper sheet dispenser, the moist
sheet dispenser comprising a receptacle housing for receiving a
stack of moist sheets, the receptacle housing comprising a
dispensing opening through which a sheet can be withdrawn from the
stack, the receptacle housing being configured to maintain
moistness of the sheets, the dispenser comprising a lid that has an
open position to provide access to the dispensing opening so that a
sheet can be withdrawn from the stack through the dispensing
opening and a closed position covering the dispensing opening,
wherein the lid defines a periphery and the receptacle defines a
periphery and the peripheries of the lid and the receptacle meet
when the lid in the closed position.
[0062] The moist sheets preferably include non-woven sheet
material. They may be made of non-woven fibres such as paper making
fibres including to a major extent polymer fibres. The moist sheets
may be a combination of non-woven and woven sheets. In the
following, the moist sheets will often be referred to as non-woven
sheets, but this is not to be construed as limiting.
[0063] In prior art moist sheet dispensers, the receptacle has a
lid and the receptacle lid includes a dispensing opening and a
cover for the dispensing opening. The cover for the dispensing
opening is provided in a central region of the receptacle lid and
is pivotably mounted to it. The two part configuration of the
receptacle lid results in a junction between the two parts that
tends to accumulate dust and other such debris. Cleaning of the
junction area after sustained use proves to be difficult. The one
part construction also enables the dispensing opening cover to be
relatively large, which may ease opening of the lid for less
dextrous users.
[0064] The present invention provides a lid for the receptacle and
cover for the dispensing opening that is one part and thus avoids
the presence of debris accumulating junction. Preferably, a top
surface of the lid (the surface opposed to the dispensing opening
side bottom surface) is continuous for ease of wiping clean as
compared to a top surface having a discontinuity as with the two
part construction of the prior art.
[0065] In order to allow loading of the receptacle with a refill of
moist sheets, the receptacle is configured to be bottom loadable.
The bottom provides an opposed face of the dispenser to the lid in
the closed configuration. Preferably, the dispenser includes a
bottom part that is removable to load moist sheets in the
receptacle. The bottom part has upstanding sidewalls that friction
fit with sidewalls of the housing in order to secure the removable
bottom to the receptacle housing. This bottom loading configuration
is an independently applicable feature of the present invention as
outlined below in the eight aspect of the present invention.
[0066] Bottom loading of the dispenser means that the lid is not
required to serve the dual functions of enabling a receptacle to be
loaded and to enable a dispensing opening to be covered.
Accordingly, the lid can be made a one part device as provided for
in the seventh aspect of the present invention. The removable
construction of the bottom part and its friction fit mechanism for
securing it to the receptacle is advantageous in terms of
manufacturing, as compared to hinge arrangements, and also in terms
of easing a sheet loading procedure. In prior art moist sheet
dispensers as described above, the lid is pivoted away from the
receptacle by way of a hinge to load the stack of moist sheets, and
the cover has to be pivoted away from the lid about another hinge
to thread a tissue sheet through the dispensing opening and then
both lids are shut. This is a relatively fiddly operation that can
be difficult to perform, particularly for elderly users. In the
bottom loading arrangement of the present invention one hinge is
not necessary, since the bottom part is removable and mountable by
friction fit. Further, bottom loading enables threading of the
sheet through the dispensing opening and moving of the stack into
the receptacle to be carried out in the same direction.
[0067] Preferably, the sidewalls of the bottom part are part of an
upstanding platform upon which a moist sheet stack is to be placed.
A platform surface on which the stack is to lay defines a bottom of
the receptacle. The bottom part may define a non-flat surface upon
which the dispenser stands, where non-flat is to be understood with
respect to the flat upper surface of the upstanding platform and
the surface of the lid when it is in the closed configuration that
is parallel to the upper surface of the platform. Thus, in one
embodiment, the bottom part defines a v shaped bottom surface for
the dispenser to stand on, which is able to mate with a v shape
upper surface as described with respect to the tissue dispenser of
the fourth and fifth aspects of the present invention.
Alternatively, the bottom part could define an arc so as to stand
on a circular toilet roll dispenser. In both cases, the point is
that an inter-fitting system of dry tissue paper and moist sheet
can be provided, whereby a room surface for the moist sheet
dispenser is not required, thereby saving space.
[0068] In a further preferred embodiment, a centre of gravity of
the dispenser lies inside the bottom part. This feature provides
stability to the moist non-woven sheet dispenser and a feeling of
permanence that is not present in prior art dispensers.
[0069] Preferably, the bottom part is made of rubber or a
rubber-like material. The rubber material provides good elastic
properties for friction fit with the receptacle and also stabilises
the dispenser with respect to the surface upon which it stands.
[0070] Preferably, the receptacle housing comprises a platform
having the dispensing opening located, preferably centrally,
therein. The platform has depending side walls defining a periphery
of the receptacle, while the platform defines a top of the
receptacle.
[0071] Preferably, the periphery of the receptacle has an
upstanding flange for mating engagement with a depending flange of
the periphery of the lid. Preferably, the flanges seal with one
another so that there is a moisture seal between the lid and the
receptacle. Preferably, the upstanding flange is formed about a
periphery of the platform.
[0072] Preferably, there is a moisture seal between the lid and the
receptacle when the lid is in the closed position.
[0073] Preferably, the dispensing opening is provided with a
deformable member that defines a relatively constricted pathway for
the tissue paper sheet as compared to the dispensing opening. The
deformable member has an opening to define the pathway for the
tissue through the dispensing opening, while squeezing the tissue
as it passes therethrough.
[0074] In an eight aspect of the present invention, there is
provided a moist sheet dispenser, the moist sheet dispenser
comprising a receptacle housing for receiving a stack of
moistsheets, the receptacle housing comprising a dispensing opening
through which a sheet can be withdrawn from the stack, the
dispenser comprising a top lid that has an open position to provide
access to the dispensing opening so that a sheet can be withdrawn
from the stack through the dispensing opening and a closed position
covering the dispensing opening, wherein the dispenser includes a
bottom part that is removable to bottom load moist sheets in the
receptacle, and wherein the bottom part has upstanding sidewalls
that friction fit with sidewalls of the housing in order to secure
the removable bottom to the receptacle housing.
[0075] The bottom part of the eighth aspect of the present
invention may include preferred features associated with the bottom
part as described above with respect to the seventh aspect of the
present invention.
[0076] Preferably, the seventh and eight aspects of the invention
provide a moist sheet dispenser that comprises the stack of moist
sheets, which is located in the receptacle.
[0077] In a ninth aspect of the present invention, there is
provided a system comprising a dry tissue paper dispenser having a
dispensing opening through which dry tissue sheets can be withdrawn
and a moist sheet dispenser comprising a dispensing opening through
which moist sheet can be withdrawn, wherein one of the dry tissue
dispenser and the moist sheet dispenser is configured to sit atop
the other so that the dispensing openings face in opposing
directions in a combined configuration, thereby defining opposing
moist and dry withdrawal directions, and wherein the dry and moist
sheet dispensers have cooperating interfacing surfaces when they
are in the combined configuration that resist lateral movement of
the moist sheet dispenser with respect to the dry tissue paper
dispenser in a direction perpendicular to a sheet withdrawal
direction of the dry tissue paper dispenser and the moist sheet
dispenser, while allowing the dispenser sitting atop the other to
move in a direction from the other dispenser's dispensing opening
to its dispensing opening.
[0078] The cooperating interfacing surfaces are preferably in the
form of male and female cooperating surfaces. The surfaces,
preferably, define substantially an entire bottom or top face of
the respective dispenser.
[0079] Preferably, the dry tissue paper dispenser includes a recess
or hole for receiving a wall fastener therein to fasten the dry
tissue paper dispenser to a room wall. The lateral direction is
perpendicular to a line normal to the room wall and to the sheet
withdrawal direction for the dry and moist sheet dispensers.
[0080] In this way, a dual moist and dry sheet dispensing system is
provided. The system has one of the dispenser mounted atop the
other, which is space saving and material, as well as being
convenient in terms of access of both types of tissue. In the prior
art, there is no designated space for a moist non-woven sheet
dispenser to be disposed as compared to, for example, conventional
toilet tissue roll holders.
[0081] The cooperating interfacing surfaces are preferably in the
form of the bottom face of the moist sheet dispenser matching a top
face of the dry tissue paper dispenser. Preferably, the cooperating
interfacing surfaces are in the form of the bottom face defining a
depending V-shape across substantially a whole extent from one side
of the bottom of the moist sheet dispenser to an opposing side
thereof, wherein the dry tissue paper dispenser has a top surface
defining a matching V-shaped recess.
[0082] Preferably, the cooperating interfacing surfaces extend in
the tissue withdrawal direction of the moist and dry tissue paper
dispensers at an angle thereto or parallel thereto in order to
resist relative movement between the dispenser in the first
direction, yet the cooperating interfacing surfaces do not resist
the dispenser sitting atop the other from being withdrawn in its
tissue paper withdrawal direction.
[0083] Preferably, the cooperating interfacing surfaces resist
movement of the moist sheet dispenser relative to the dry tissue
paper dispenser in first and second perpendicular directions in a
lateral plane extending perpendicularly to the tissue withdrawal
direction.
[0084] The dry tissue paper and the moist non-woven sheet
dispensers of the eighth aspect of the present invention may be
according to those previously described in the first to seventh
aspects of the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
[0094] Improved absorbent tissue paper systems are provided by the
present invention in its various aspects.
[0095] There is provided a package of tissues that can be broken
open by grasping opposing longitudinal ends of the package and
applying relative force to a backside of a perforation line
positioned centrally between the longitudinal ends and which
extends laterally. The perforation line extends about at least
three sides of the package so that at least part of a fourth side
provides a hinge portion connecting the longitudinal halves of the
package together and also allowing the broken perforation line to
be brought together for closing the package and to be brought apart
for opening the package in a rotational motion about the hinge. In
a closed configuration, the package is block shaped. In an open
configuration, the package is flexed into a V-shape in a side view,
wherein the opposing longitudinal halves and the hinge portion
provide an inside edge of the V-shape and bottom surfaces of the
opposing longitudinal halves provide an outside edge of the V-shape
in combination with a portion of the package opposed to the hinge
that has been moved apart by spreading apart opposing edges of the
perforation line. The open perforation line reveals a stack of
tissues comprised in the package. A tissue can be withdrawn from
the stack and the package through a dispensing opening provided by
the open perforation line at a side opposite to the hinge
portion.
[0096] In the open configuration of the package, a bottom side of
the perforation line extends between opposing sides of the
perforation line. The opposing sides of the perforation line
respectively connect opposing ends of the bottom side of the
perforation line to the hinge portion. In the open configuration,
the sides of the perforation line become more spread apart towards
the bottom side of the perforation line. A stack of tissues is
arranged in the package so that a pull tab portion of the tissue
most proximal to the bottom side of the perforation line extends
through the bottom side of the perforation line. The bottom side of
the perforation line thus provides a dispensing opening through
which tissues in the stack can be withdrawn.
[0097] The dispensing opening has opposing first and second lip
members disposed on respective sides of the dispensing opening,
which overlap with one another so as to cover the tissue facing the
dispensing opening in all but a central opening through the
overlapping lip members through which a pull tab portion of a
tissue in the stack most proximal to the dispensing opening can be
grasped by a user. The first and second overlapping lip members are
movable relative to one another. They are respectively attached to
opposing halves of the package so that as one half of the package
is moved relative to the other half of the package about the hinge
portion, the overlapping lip members move with them and relative to
one another. In the opened configuration of the package and in the
closed configuration, the lips overlap. As a tissue is withdrawn
from the stack and through the dispensing opening, the overlapping
lip members deform into a less overlapping configuration so as to
ease passage of the tissue from between the lip members in the
tissue withdrawal direction.
[0098] The package includes at least one cover member for covering
the tissue that is revealed by the package as at least one of the
side perforations opens. The dispensing opening reveals a face of
the stack of tissues when it is in the open configuration, while
the side perforation reveals the layer of tissue in the stacking
direction when it is in the open configuration. The cover is
transparent so as to allow a level of the tissues in the package to
be viewed so that the user gets an idea as to how close the package
is to being empty.
[0099] The tissues in the stack in the package are interfolded so
that each tissue in the stack is partially overlapped with a
preceding tissue in the stack so as to pull the preceding tissue
partially through the dispensing opening and the overlapping lips
as a result of the face-to-face partial overlap of each tissue with
a preceding tissue. The portion of the preceding tissue that was in
overlapping relation with a tissue that has been withdrawn from the
stack through the dispensing opening and the overlapping lips thus
sticks out through the overlapping lips as a tissue that will next
be grasped by a user. The interfolding pattern is such that when a
first tissue is pulled out through the overlapping lips, the next,
second, tissue will be on a left hand side face, for example, of
the first tissue and the tissue after that, the third tissue, will
come out on a right hand side face, for example, of the second
tissue. This alternation of sides with respect to the tissue being
pulled out at which the overlapping portion occurs results in the
first and second lip members alternating with respect to which of
the first and second lip members is more forward in the tissue
withdrawal direction than the other.
[0100] The package of tissues is self supporting in that it can
hold the opened configuration, even with the weight of gravity in
the hinge portion. This allows the dispensing opening to be top up
for positioning on a counter top for tissues to be withdrawn from
it in a style familiar to that known from a conventional facial
tissue box. The package may also be used in an upside down
configuration so that the dispensing opening faces downwards. In
the latter configuration, the present invention contemplates a
dispenser that is wall mountable and has a cavity for holding the
opened configuration of the package. When the opened configuration
of the package is V-shaped as described previously, the cavity of
the dispenser is correspondingly V-shaped, whereby walls defining
the cavity are dimensioned so as to fittingly receive the package
in the opened configuration. The shape of the cavity as defined by
the dispenser prevents the package from moving back to a block
shaped closed configuration and thus holds the package in the
opened configuration. The dispenser has a dispensing opening on a
bottom surface thereof for aligning with the dispensing opening of
the package so that tissues can be withdrawn through the dispensing
opening and the overlapping lips of the package and through the
dispensing opening of the dispenser. The dispenser can be a
relatively low complexity structure in that it consists of a back
wall for mounting against a room wall and a sidewall protruding
therefrom that extends about the cavity in a continuous manner from
one side of the dispensing opening, about each side of the cavity
defining a V-shape, to the other side of the dispensing
opening.
[0101] A dispenser as described above has a V-shaped recess defined
by a top surface of the sidewall, where the top surface is opposed
to a bottom surface of the sidewall that includes the dispensing
opening that is centrally located between opposed longitudinal ends
of the cavity defined by the sidewall. The V-shaped recess is so
shaped to receive a depending V-shape of a bottom part of a moist
non-woven dispenser. Accordingly, the top surface of the dry tissue
dispenser provides a specially designed space for a moist non-woven
sheet dispenser.
[0102] The moist non-woven dispenser has a bottom part defining a
depending V-shaped bottom surface for cooperating and interfacing
with the V-shaped top surface of the dry tissue dispenser. The
moist non-woven sheet dispenser includes a receptacle for receiving
a package of moist non-woven sheets or a stack of moist non-woven
sheets and a lid that is mounted by a hinge to a housing of the
receptacle. The hinge allows the lid to open so as to reveal a
dispensing opening of the receptacle housing through which moist
non-woven sheets can be dispensed. The hinge also allows the lid to
be closed so as to seal with the receptacle housing to prevent
moisture from the tissues escaping from the moist non-woven sheet
dispenser. A periphery of the lid mounts with a periphery of the
receptacle housing so as to present a continuous easy wipe top
surface of the moist non-woven sheet dispenser. A bottom part of
the moist non-woven sheet dispenser, which includes the depending
V-shape, is removable and is friction fit remountable to the
receptacle housing. The bottom part includes an upstanding platform
that engages with sidewalls of the housing in a friction fit manner
and also provides an even surface upon which the stack or package
of moist non-woven sheets sits. Thus, the platform provides a
bottom surface of the receptacle housing, which removably mates
with sidewalls of the housing. The receptacle housing also includes
a top surface having the dispensing opening centrally located
therein. The sidewalls of the receptacle housing define the
periphery of the receptacle housing, which sealingly mates with the
periphery of the hinged lid.
[0103] Various components of the improved tissue system outlined
above will now be described in greater detail with respect to the
figures.
[0104] FIG. 1 shows a package comprising a stack of tissues
according to an embodiment of the present invention. The package 1
has an open configuration as shown in FIGS. 1 a and 1 c and a
closed configuration as shown in FIG. 1 b. In the closed
configuration, the package 1 is generally block-shaped. The package
1 has first and second major faces provided by respective top and
bottom face walls 2, 3 of the package. At opposing longitudinal
ends of the package 1, there is end face walls 4, 5, which are
minor faces of the package 1. The package 1 further comprises back
and front face walls 6, 7, which are intermediate in area size
between the major top and bottom faces 2, 3 and the minor end faces
4, 5.
[0105] The package 1 comprises a perforation line 8 extending
through the back and front face wall 6, 7 and the bottom face wall
3 of the package 1. The perforation line 8 is located centrally
between opposing ends 4, 5 of the package 1 and extends
perpendicularly to a longitudinal direction of the package 1. The
top face wall 2 of the package 1 comprises a hinge 9 connecting the
end of the perforation line at the front face wall 7 and the other
end of the perforation line 8 at the back face wall 6 of the
package 1.
[0106] The package 1 is filled with a stack of interfolded tissues
10. In a closed configuration of the package 1, the stack of
interfolded tissues 10 is entirely covered by the package 1.
[0107] In an opened configuration of the package 1, the perforation
line 8 is broken apart and opposing halves, in the longitudinal
direction, of the package 1 are connected by and rotatable about
the hinge 9. The opened configuration of the package 1 can be seen
in FIGS. 1a and 1c, while the closed configuration of the package 1
can be seen in FIG. 1b. In the opened configuration, a gap between
opposing parts of the bottom face wall 3, which have come apart as
a result of the perforation line 8 being broken, provides a
dispensing opening 11 through which a tissue can be withdrawn from
the stack 10. The back and front face walls 6, 7 of the package 1
also have respective parts that are spaced apart from one another
about the hinge 9 in the opened configuration of the package 1. The
gap between the back and front face parts comes to nothing at the
hinge 9 at a top edge of the back and front face walls 6, 7 and is
at its widest at a bottom edge of the back and front face walls 6,
7 in the opened configuration of the package 1.
[0108] The back and front face walls 6, 7 and the end face walls 4,
5 define a thickness of the package 1 connecting the top and bottom
faces 2, 3. The number of tissues that can be stacked and fit
within the package 1 is determined by the thickness of the package
1, i.e. it defines the sheet stacking direction of the absorbent
tissue paper. The tissues in the stack 10 and the stack 10 itself
is elongate and the tissues and the stack 10 are longitudinally
aligned with the longitudinal direction of the package 1 when the
package is in the closed configuration. The distance between the
end face walls 4 and 5, as defined by the back and front face walls
6, 7 and the top and bottom face walls 2, 3, determines the
longitudinal extent of the stack 10. An interfolding pattern of the
tissues in the stack 10 is such that a pull end of a tissue, which
is a laterally extending edge of the tissue, is located at the
dispensing opening 11 of the package 1. The thickness direction of
the package 1 is dimensioned to be convenient for grasping in the
hands of a user at opposed longitudinal ends of the package 1.
Typical dimensions of the thickness direction of the package 1 are
from 5-10 cm, preferably about 7 cm.
[0109] To use the package, a user grasps opposing longitudinal ends
of the package 1 so that the fingers and thumbs are positioned in
contact with the top and bottom face walls 2, 3 of the package 1
and part of the palms are in contact with respective end face walls
4, 5. With the package 1 so grasped, the user flexes the package so
as to provide a rotational force about the hinge 9 tending to pull
the perforation line 8 apart. The perforation line 8 is thus broken
to reveal a stack of tissues 10 in the stacking direction by
viewing through the gap made by the broken perforation line 8 in
the front or back face wall 6, 7 and to reveal a plane of a face of
a forward most tissue when viewing through a gap between opposing
parts of the bottom face 3, which gap provides the dispensing
opening 11. A tissue can be withdrawn from the stack 10 through the
dispensing opening 11.
[0110] When the package 1 is first opened, a forward most tissue in
the stack 10 relative to the dispensing opening 11 is designed to
have an edge portion that protrudes through the dispensing opening
11. This edge portion of the tissue can be pulled upon to withdraw
a tissue from the stack 10 through the dispending opening 11. The
interfolding pattern of the tissues of the stack 10 is such that as
one tissue is pulled through the dispensing opening 11, a
subsequent tissue is partially pulled through the dispensing
opening 11 to protrude through the dispensing opening 11 to provide
a subsequent end edge of a tissue for withdrawal from the stack
10.
[0111] The package 1 can be reclosed by rotating the partially
separated parts (connected only by the hinge 9) about the hinge 9
to bring the line of weakness 8 back together. To dispense a
further tissue from the stack 10, the package 1 can be reopened by
rotation about the hinge 9.
[0112] The skilled person may contemplate various modifications to
the specific embodiments of the package 1 shown in FIG. 1.
[0113] For example, various modifications could be made to the
exact shape of the package 1 shown in FIG. 1. For functional
reasons it has been preferred that the package 1 be elongate and
the perforation line 8 and the hinge 9 be provided in a central
location between longitudinal ends of the package 1. In this way, a
turning moment about the hinge 9 can be utilised to make it feel
easy to break the perforation line 8. It is also desirable that the
longitudinal ends of the package 1 can be conveniently grasped by a
user in order to apply the perforation line 8 breaking force. Thus,
a thickness of opposing longitudinal end portions of the package 1
in the direction of the hinge 9 to the dispensing opening 11 should
be conveniently graspable and thus of the order of the dimensions
of a gap able to be made between the fingers and the opposed thumb
by an average human adult.
[0114] In FIG. 1, a line of weakness is provided in the form of a
perforation line 8. The skilled person can contemplate alternatives
such as a line of weakness in the form of a cut that passes only
partly through a thickness of the wall of the package and thus does
not reach the inside of the package 1. That is, the line of
weakness could be a score line. The perforation line 8 could be
made in a number of ways. The perforation line 8 could extend
continuously by way of alternating cut and tap portions through the
front face 7, the bottom face 5 and the back face 6. Alternatively,
the front face 7, the bottom face 3 and the back face 6 could be
divided by a cut line extending most of the way there around, apart
from a few small connecting tab portions that are broken by flexing
of the package 1.
[0115] The tissues in the stack 10 of the package 1 are disclosed
as being interfolded. The stack 10 could, however, be made of a
continuous web of tissues folded into a stacked arrangement that
fills the package 1 and where adjacent sheets are connected by
lines of weakness, rather than an overlapping face-to-face
interfolding arrangement. Important is that the tissue is stacked,
rather than rolled about a central core.
[0116] The package 1 has been described as having top and bottom
face walls 2, 3, which suggests that the dispensing opening 11
faces downwards in use. In one envisaged use this is correct. The
package 1 is, however, configured also to be tipped up so that the
dispensing opening 11 faces upwards. The package 1 is configured to
operate in this way in that the hinge 9 does not collapse under the
weight of the stack 10 when the dispensing opening 11 is faced
upwards. That is, the package 1 is sufficiently stiff to maintain
the opened configuration, no matter which orientation the package 1
is placed in. The package 1 is closed by a user forcing it closed
by rotation about the hinge 9.
[0117] The hinge 9 of the package 1 forms a fold line connecting
opposing ends of the line of weakness or perforation line 8. The
package 1 is, as described above, designed to rotate about the
hinge 9 in opening and closing the package 1. The hinge 9 may
define a fold line as a result of its first use, or the fold line
may be prefabricated into the package 1, such as by a coining
technique or the like.
[0118] The package 1 could have a tear off strip defined by a pair
of spaced apart lines of weakness. When a tab of the tear off strip
is pulled upon, the lines of weakness tear away to provide a torn
off strip. When the tear away strip is fully torn away, the lines
of weakness are broken and the package is able to be manipulated
from a relatively closed configuration to a relatively opened
configuration by rotation about the hinge. Thus, the pair of lines
of weakness defining opposing sides of the tear away strip
preferably extends around a majority of a lateral periphery of the
package in the same way as the break open type line of weakness
described above.
[0119] FIG. 2 shows various views of a dispenser for holing a
package of tissues. The dispenser 20 is wall mountable, as will be
discussed below with respect to FIG. 3. The dispenser 20 has a
peripheral wall 21 extending in a normal direction to a back face
wall 22. The peripheral wall 21 and the back face wall 22 together
define a cavity 23 for receiving a package 1 of tissues therein,
where the package 1 is as described above. A front face of the
dispenser 20 is open in order to allow the package 1 to be loaded
into the cavity 23. The rear face 22 is for mounting to a room
wall, as will be described in further detail with respect to FIG.
3.
[0120] The peripheral wall 21 extends continuously about the cavity
23 and about a periphery of the rear face wall 22 except so as to
define a gap in the peripheral wall 21, which provides a dispensing
opening 24 through which a tissue can be withdrawn from a package
dispensing opening from a package 1 as described above. The
peripheral wall 21 of the dispenser defines a V-shape in that a top
wall portion 25 and a bottom wall portion 26 of the peripheral wall
21 respectively follow V-shaped paths. The V-shape of the bottom
wall portion 26 of the peripheral wall 21 can be constructed by
imagining the bottom wall portion 26 not defining a dispensing
opening 24 and instead continuing to intersect. The V-shaped bottom
wall portion 26 and the V-shaped top wall portion 25 of the
peripheral wall 21 are separated by end wall portions 27, 28 of the
peripheral wall 21, which defines a thickness dimension to the
V-shape of the cavity 23.
[0121] The peripheral wall 21 of the dispenser 20 is designed to
fittingly mate with respective top and bottom face walls 2, 3 and
end face walls 4, 5 of the package 1, when the package 1 is in the
opened configuration. Further, in a depth direction of the
dispenser 20, which is from the rear wall 23 to the open end face,
the dispenser is designed to match with a corresponding depth of
the package 1 so that when the package 1 is inserted into the
dispenser 20, a front face 7 of the package 1 lies flush with a
front end of the peripheral wall 21.
[0122] An angle .alpha. between legs of the V-shape of the cavity
23 is preferably in a range from 130.degree.-160.degree. and
preferably about 150.degree.. An angle .beta. is defined as shown
in FIG. 1(c), which is the angle traversed by the dispensing
opening 11 as compared to a 0.degree. closed configuration of the
dispensing opening 11. The angle .beta. of the dispensing opening
11 about the hinge 9 is preferably in the range of
20.degree.-50.degree.. The form of the dispenser 20 determines the
opening angle of the package 1 by holding the package 1 open at
that angle .beta. in the opened configuration.
[0123] The package 1 is designed to be flexible so that it can be
flexed for a user to break open the perforation line 8 to open the
package 1. The dispenser 20 is a stiffer, relatively non-flexible
flexible structure that is able to better hold the opened
configuration of the package 1 and which is able to be mounted to a
room wall at the back wall 22 of the dispenser 20 and take the load
of the package 1 therein without deforming under the load. The
dispenser 20 may be made of relatively thick molded plastic or
metal. The package may be made of a plastic film, cardboard or
paper.
[0124] To use, the package 1 may first be broken open as described
above to put it into the opened configuration. The opened package
may then be inserted in the dispenser through the open front face.
Alternatively, manipulation of the package into the cavity 23 will
tend to pull the perforation line 8 apart so as to open the package
1. As the package is pushed into the cavity 22 of the dispenser 20,
a peak of the V-shape of the top wall part 25 of the peripheral
wall 21 provides a first pressure point against the hinge 9 of the
package 1. The bottom wall part 16 of the peripheral wall 21
provides second and third pressure points on either side of the
dispensing opening 24 of the dispenser 20 against the bottom wall
face 3 on either side of the perforation line 8. Thus, a three
point load is applied to the package 1, which will break open the
perforation line 8 so as to open the package 1. The package 1 can
be pushed fully into the dispenser 20 as shown in FIGS. 2c and 2d
so that the peripheral wall 21 is in sliding relation with the top
and bottom faces 2, 3 and the end faces 4, 5 of the package 1. The
package 1 can be slid back until a back wall 22 of the dispenser 20
is contacted flush against a back wall 9 of the package 1.
[0125] The package 1 is held by the dispenser 20 in an opened
configuration as shown in FIG. 2d. The dispensing opening 11 of the
package 1 is aligned with the dispensing opening 24 of the
dispenser 20 so that a tissue passes through the dispensing opening
11 of the package 1 and through the dispensing opening 24 of the
dispenser 20 when a tissue is withdrawn from the stack of tissues
10 in the package 1. The angle defined by the cavity 23 defines the
angle of the opened configuration of the package 1 because of the
close conformance between top and bottom face walls 2, 3 and end
face walls 4, 5 of the package 1 and the peripheral wall 21 of the
dispenser 20. In the V-shaped opened configuration of the package
1, an angle between the legs is according to the ranges given
above, which are such that a sufficient size dispensing opening 11
of the package 1 is provided, yet the angle is not so great that
the weight of the tissues in the stack 10 tends to pull the stack
through the dispensing opening 11 without a user pulling a tissue
of the stack.
[0126] Various modifications could be made to the dispenser 20
according to that described above. For example, the dispenser 20
could be filled by a stack of tissues that are not provided in a
package form. Such a stack of tissues would be interfolded or
folded so that a pull end of each tissue occurs at the location of
the longitudinal central dispensing opening 24. In this case of the
dispenser 20 itself forming a package for a stack of tissues, the
dispensing opening 24 may be more constricted than that shown in
FIG. 2a in order to avoid the stack of tissues unintentionally
falling through the dispensing opening 24.
[0127] FIG. 3 shows a wall mounting means for mounting the
dispenser as described above with respect to FIG. 2 to a room wall.
In the figure, there is shown a tiled room wall for illustrative
purposes. The dispenser 20 has a recess 30 provided in a back wall
22 of the dispenser 20. The recess 30 in the back wall is a
continuation of the dispensing 2 5 opening 24 provided in the
peripheral wall 21 that extends in a direction normal to the back
wall 22. The recess 30 is open at a bottom edge so that the
dispenser 20 can be moved with respect to a fastening member 31
already fastened on a room wall to receive the fastening member 31
in the recess 30.
[0128] The fastening member 31 is plate-like and has a peripheral
edge defining a thickness direction of the plate that is bifurcated
so as to provide opposing lips 33, 34 having a recess therebetween.
The opposing lips 33, 34 are dimensioned so that when the fastening
member 31 is received in the recess 30 of the dispenser 20, the
opposing lips 33, 34 engage on opposing faces of the back wall 22
of the dispenser 20. That is, the recess 32 of the fastening member
31 receives an edge of the recess 30 of the back wall 22 when the
dispenser 20 is mounted to the fastening member 31. The fastening
member 31 can be attached to the room wall using adhesive or other
means such as screws.
[0129] To mount the dispenser 20 to a room wall, the fastening
member 31 is adhered to the room wall. The dispenser 20 is
positioned above the fastening member 31 and slid downwardly so
that an edge, in the thickness direction of the recess 30 of the
dispenser 20, is received in the recess 32 of the fastening member
31 so that the lips 33, 34 contact opposing faces of the rear wall
22 of the dispenser 20. The recess 32 of the fastening member 31
extends about three sides of the fastening member 31 including a
top side portion and side portions extending in a depending manner
therefrom so as to correspondingly receive top and side portions of
the edge of the recess 30 of the dispenser 20 in the recess 32 of
the fastening member 31. In this way, the dispenser 20 is secured
to the fastening member 31 and thus to the room wall, in a
direction normal to the room wall and in left, right and down
directions as one faces the room wall and the dispenser 20. The
dispenser 20 is only able to be dismounted from the fastening
member 31, and thus the room wall, by moving it in a direction
opposite to which the dispenser 20 is slid onto the fastening
member 31 during mounting. That is, to remove the dispenser 20 from
the room wall and the fastening member 31, the dispenser 20 must be
moved in an upward direction until an edge of the recess 30 comes
out of contact, and out of being disposed between, the first and
second lips 33, 34 of the fastening member 31. Thus, the fastening
member 31 enables the dispenser 20 to be moved into a released
configuration so as to be out of contact with the fastening member
31, which may prove useful for tissue loading and cleaning
purposes.
[0130] Modifications may be made to the specific embodiment shown
in FIG. 3 for enabling the fastener 20 to be mounted to a room
wall. For example, the fastening member 31 or indeed the dispenser
20 could have suction cups to secure it to the room wall.
Alternatively, a fastening member mounted to the room wall and the
dispenser could have a magnetic cooperation for holding them
together. In another example, the dispenser 20 could be affixed
directly to the room wall by way of screw receiving holes through
which screws are drilled into the room wall to clamp the dispenser
20 against the room wall. In another possibility, the dispenser 20
could define at least one channel having an enlarged opening
through the back wall 22 of the dispenser 20. The enlarged opening
in the channel is sized to allow an enlarged head of a fastening
member that protrudes from the room wall to enter into it. The
dispenser 20 can then be moved relative to the fastening member 31
so that the enlarged head of the fastening member slides within the
channel to a position where the fastening member 31 cannot pass out
of the channel in a direction normal to the room wall, and
preferably also in left and right directions as a user faces the
dispenser 20 and the room wall. In order to remove the dispenser 20
from the fastening member 31 in such a configuration, the enlarged
head must be moved through the channel until it reaches the
enlarged opening when the dispenser 20 can then be moved in a
direction normal to the room wall to detach it from the room wall
and the fastening member 31.
[0131] It is, however, preferred that the fastening member 31 and
the dispenser 20 be mounted to one another by sliding the dispenser
20 from a position displaced from the fastening member 31 to a
position overlaying the fastening member 31 whereat they cooperate
so that movement of the dispenser 20 relative to the fastening
member 31 is prevented in a direction normal to the room wall/plane
of the fastening member and/or where relative movement is only
possible in a direction opposite to the initial direction to
slidably mount the dispenser 20 to the fastening member 31.
[0132] FIGS. 4a, 4b and 4c show various views of a package
comprising a stack of tissues in accordance with a preferred
embodiment of the present invention. The package 1 is substantially
as hereinbefore described with reference to FIG. 1 in that it is
openable and closable by breaking open a perforation line 8 as the
package 1 is flexed in a rotational direction about the perforation
line 8. The package 1 of FIGS. 4a to 4c further comprises lip
members 40, 41 that overlap when the package 1 is in the opened
configuration as shown in FIGS. 4b and 4c. The overlap is in the
tissue withdrawal direction in that a tissue withdrawal direction
line 42 passes through both the first and the second lips. The
tissue withdrawal direction line is a line that passes through a
centre of the dispensing opening, where centre is to be understood
as the centre between the opposed parts of the package 1 in the
direction in which they move apart in going from the closed
configuration to the opened configuration of the package 1. Looked
at in another way, the first lip member 40 has a major face that is
in face-to-face relation with a major face of the second lip member
41 at an overlapping portion of the first and second lip members
40, 41.
[0133] The first and second lip members 40, 41 are flexible in that
they are able to deflect downwardly in the tissue withdrawal
direction 42 and as they do so, the first and second lip members
40, 41 move apart into a non-overlapping relation (not shown). In
FIG. 4b, the first lip member 40 is shown to be more forwardly
disposed than the second lip member 41 in the tissue withdrawal
direction 42. The first and second lip members 40, 41 are flexible
enough to be able to move into the opposite configuration, whereby
the second lip member 41 is more forwardly disposed than the first
lip member 40 in the tissue withdrawal direction 42. Further, the
first and second lip members 40, 41 are resilient in that after
deformation in the tissue withdrawal direction and into a
non-overlapping state, they resiliently reform into an overlapping
state.
[0134] Referring to FIG. 4c, the overlapping lips 40, 41 can be
seen in a plane view of a bottom face 3 of the package 1. The
overlapping lips 40, 41 are shown with the package 1 empty of
tissues so that both lips 40, 41 can be seen. If there was tissue
in the package 1, the lip 41 would be covered by a pull tab portion
of a bottom-most tissue closest to the dispensing opening 11 that
protrudes through the dispensing opening 11 and the lips 40, 41.
The overlapping lips extend across the dispensing opening 11 of the
package 1 when the package 1 is in the opened configuration in a
longitudinal direction of the package 1. The dispensing opening 11
is provided in a bottom face 3 of the package and extends between a
front face 7 and a back face 6 of the package 1 to provide a
dispensing opening 11 that is open along a full width of elongate
tissues in the stack of tissues 10 in the package 1 so as to avoid
crumpling of the tissues in the width direction of the tissues
during dispensing. The overlapping lips 40, 41 likewise extend
substantially along the full length of the dispensing opening 11,
which is from a front face wall 7 to a back face wall 6 of the
bottom face 3 of the package 1. The lips 40, 41 overlap at a
opposing ends in a length direction of the elongate dispensing
opening 11, where overlap is to be understood in the context of the
lips 40, 41 being deformed in the tissue withdrawal direction 42
into a non-overlapping state. There is thus provided overlapping
portions 43 of the overlapping lips 40, 41 at opposing longitudinal
ends of the dispensing opening 11 and a central non-overlapping
portion 44 disposed longitudinally between the opposing overlapping
portion 43. The overlapping portions 43 cover the tissue in a
tissue withdrawal direction 42 while the non-overlapping portion 44
leaves the tissue in the package 1 uncovered in the tissue
withdrawal direction 42. The non-overlapping portion 44 allows a
user to reach through the lips 40, 41 to grasp a tissue most
proximal to the dispensing opening 11 in order to pull a pull tab
portion of that tissue through the dispensing opening 11 and
through the overlapping lips 40, 41 for subsequent dispensing.
[0135] In use, a closed package 1 as shown in FIG. 4a is taken and
the perforation line 8 is broken apart by rotating opposed
longitudinal parts of the bottom face 3 on either side of the
perforation line 8 about the hinge 9 in a direction so that the
opposing parts of the bottom face 3 are moved apart and the
perforation line 8 is thus broken. In the closed configuration 1,
the overlapping lips 40, 41 are disposed in a most overlapping
state with a tissue 45 positioned between the more forward lip 40
in the tissue withdrawal direction 42 and a less forward lip 41 in
the tissue withdrawal direction 42. In the closed configuration
shown in FIG. 4a, before the perforation line 8 is broken, the
overlapping lips 40, 41 are confined inside the walls of the
package 1. As the package 1 is opened as described above, the lips
40, 41 move apart as they are attached at one end to the opposing
parts of the bottom face wall 3 on either side of the perforation
line 8. The lips 40, 41 thus move from a most overlapping
configuration when the package is closed to a less overlapping, but
still overlapping, configuration as shown in FIG. 4b.
[0136] Referring to FIG. 4b, with the package 1 in the opened
configuration, the tissue 45 most proximal to the dispensing
opening 11 has a portion protruding through the dispensing opening
11 and protruding from between (in the tissue withdrawal direction
42) the overlapping lips 40, 41 so as to provide a pull tab portion
of the tissue 45 for grasping by a user to dispense the tissue 45.
The overlapping lips 40, 41 contact opposing faces of the tissue 45
protruding through the lips 40, 41.
[0137] As a user pulls on the tissue 45 in the tissue withdrawal
direction 42, the more forwardly disposed lip 40 is deformed in the
tissue withdrawal direction 42, which also places the lips 40, 41
in a non-overlapping configuration. The subsequent tissue in the
stack adjacent the tissue 45 being pulled through the dispensing
opening 11 and the lips 40, 41 is pulled with the tissue 45 in the
tissue withdrawal direction 42 because the subsequent tissue 46 and
the tissue 45 being dispensed are in face-to-face contact. The
subsequent tissue 46 comes out through the lips 40, 41 so that the
tissue 45 is in contact with the more forwardly disposed lip in the
tissue withdrawal direction 42 and the subsequent tissue 46 is in
contact with the less forwardly disposed lip 41 in the tissue
withdrawal direction 42. As the first tissue 45 in the tissue
withdrawing sequence of the stack of tissues 10 is pulled through
the dispensing opening 11 to such an extent that the next tissue 46
in the tissue withdrawal sequence of the stack of tissues 10 comes
into contact with the lip 41, the lip 41 is further deformed in the
tissue withdrawal direction 42 to allow the subsequent tissue 46 to
be pulled through the first and second lips 40, 41. Once the first
tissue 45 is pulled completely through the dispensing opening 1 and
the lips 40, 41 so that the tissue 45 is no longer in contact with
either of the lips 40, 41, that tissue 45 has been dispensed. At
this point, the lip 41 falls back to its original non-deformed
state at a slower rate than the lip 40 because of the contact of
the subsequent tissue 46 with it. Accordingly, the previously more
forwardly disposed lip 40 falls back so as to be behind the
previously more rearwardly disposed lip 41 in the tissue withdrawal
direction 42. The lips 40, 41 have thus alternated with respect to
which of the lips is more forwardly disposed as each tissue is
dispensed.
[0138] The tissue 46 is now the first tissue in the tissue
withdrawal sequence of the stack of tissues 10 and protrudes
through the lips 40, 41 to provide a pull tab portion for grasping
by a user to dispense the tissue 46. This sequence of steps repeats
for each subsequently withdrawn tissue with the overlapping lips
alternating as to which of the lips is more forwardly disposed.
[0139] The overlapping portions 43 of the overlapping lips 40, 41
contact opposing faces of the tissue being withdrawn through the
dispensing opening 11 at opposing lateral portions of the elongate
tissue as it is being withdrawn in a longitudinal direction of the
tissue. This contact of opposing faces of the tissue being
withdrawn by the overlapping portions 43 of the overlapping lips
40, 41 is a pinching type contact on opposing faces of the tissue.
In the non-overlapping portion 44 of the lips 40, 41, the tissue
being withdrawn may be contacted by one or the other of the lips
40, 41, but the contact is not so as to pinch the tissue as it is
being withdrawn. Pinching of opposing lateral portions of an
elongate tissue as it is being withdrawn, with a central lateral
portion between the opposing lateral portions of the tissue not
being pinched, tends to avoid crumpling of the tissue in a lateral
direction during dispensing.
[0140] The above description of the overlapping lips 40, 41 has
been given in the context of a package 1 as described previously
with respect to the embodiments of FIGS. 1 and 2. Such a package 1
is disposable and is thus made of less hardwearing materials such
as a thin polymer wrap, paper or cardboard. In an alternative
embodiment, the overlapping lips could be applied on either side of
a more hardwearing container for a stack of tissues. Such a
container could be wall mountable and made of suitably rigid
polymers or metal. The overlapping lips 40, 41 would be arranged on
opposing lateral sides of an elongate dispensing opening for such a
container. The lips would be attached to the container on either
side of the dispensing opening and extend across the dispensing
opening in a cantilevered manner so as to partially overlap such
that a line normal to a plane of the dispensing opening would pass
through both lips where they overlap. The lips would be shaped and
function as described above with respect to FIGS. 4a-4c. For a
container having a fixed dispensing opening, the description of the
overlapping lips 40, 41 with respect to the closed configuration of
the package 1 may not be applicable. With a fixed dispensing
opening 11, that is a dispensing opening 11 that is not formed by
opposing parts of a container or package that move away from one
another, the overlapping lips would not move from a more
overlapping configuration as shown in FIG. 4a to a less
overlapping, but still overlapping configuration, as shown in FIG.
4b.
[0141] In one aspect of the present invention, the package 1
comprising a stack of tissues 10 also comprises a cover 50 for
covering the stack of tissues 10 in a thickness or stacking
direction of the stack of tissues 10 when the package 1 is in the
opened configuration, as shown in FIG. 5. The stack of tissues 10
has opposing major faces provided at least in part by a first and
last tissue in a stacking sequence of the stack of tissues 10. The
package 1 opens at the dispensing opening 11 so as to reveal the
major face of the stack of tissues 10 corresponding to the first
tissue in the stack 10. A hinge 9 of the package 1 is provided
across, in a lateral direction, of an opposing major face of the
stack of tissues 10 so that the package 1 opens about the hinge 9
to provide the dispensing opening 11. Connecting the hinge 9 and
the dispensing opening 11 are opposing front end rear face walls 6,
7 of the package 1 that also open about the hinge 9 so as to reveal
the stack of tissues 10 in a thickness direction of the stack of
tissues 10.
[0142] The opening in the back and front face walls 6, 7 of the
package 1 is greater in extent toward the dispensing opening 11
from the hinge 9 when the package 9 is in the opened configuration.
The opening is between opposing parts or, in the shown embodiments,
halves 51, 52 of the front and back face walls 6, 7 when the
package 1 is in the opened configuration. The cover 50 is attached
to one of the parts 51, 52 on a front face 7 of the package 1 and
extends across the opening between the opposing parts 51, 52 of the
front face 7 to the other part 51, 52 to protect the stack of
tissues 10 from contamination, such as by dust. The cover 50 is
attached to one of the parts 51, 52, yet is unattached to the other
part 51, 52 of the front face 7 when the package 1 is in the opened
configuration so that it moves with one of the parts 51, 52 and is
slidable with respect to the other part 51, 52. The cover 50 is
attached to one of the parts on the inside of the package 1. In the
closed configuration of the package 1, before the perforation line
8 is broken, the cover 50 is covered by the package 1 so that the
cover 50 is inside the package 1.
[0143] The cover 50 is triangular in shape so that a peak of the
triangle is positioned at the hinge 9 side of the opening between
the opposing parts 51, 52 of the front face 7 when the package 1 is
in the opened configuration and a base of the triangle defined by
the cover 50 is disposed at a dispensing opening 11 side of the
front face 7. In this way, the shape of the cover 50 conforms to
the shape of the opening between the opposing parts 51, 52 of the
package 1 when the package 1 is in the opened configuration. The
cover 50 thus provides an effective dust cover for the full extent
of the stack of tissues 10 that would otherwise be revealed in the
stacking direction when the package 1 is in the opened
configuration.
[0144] In use, the package 1 is grasped at opposing longitudinal
ends thereof with the fingers on a bottom face wall 3 of the
package 1 thumbs on a top face wall 2 of the package 1 and palms
contacting opposing longitudinal end face walls 4, 5 of the package
1, as shown by the hands 54 in FIG. 5. The thumbs are pushed into
the top face of the package 1, while the fingers of the hand 54 are
moved apart so as to break a line of perforation 8 to provide a
dispensing opening 11 in the bottom face wall 3 of the package 1, a
hinge 9 in the top face wall 2 of the package 1 and front and 2 5
rear openings in the package 1 that connect the hinge 9 and the
dispensing opening 11. Parts 51, 52 of the package 1 move apart
from one another as the package 1 is opened about the hinge 9. The
cover 50 moves with the part 51, 52 of the package 1 that it is
attached to and slides relative to the other part 51, 52. The cover
50 provides a dust cover when the package 1 is in the opened
configuration covering the stack of tissues 10 in the stacking
direction of the tissues.
[0145] The cover 50 is preferably transparent so that a user can
view through it to determine a level of depletion, which is
determined by the number of tissues left in the stack 10, of the
package 1. The cover 50 may be made of a polymer film.
[0146] In a modification of the package 1 shown in FIG. 5, a cover
50 could be provided on opposing faces of the package 1, where
those faces extend in the stacking direction of the stack of
tissues 10. Thus, in the shown embodiment of FIG. 5, a cover 50
would be provided that covers an opening between opposing parts 51,
52 of the package 1 in the rear face wall 6 and the front face wall
7 of the package 1.
[0147] In another modification of the embodiment shown in FIG. 5,
the cover 50 could be attached on an outside of the package 1.
Aesthetically this modification may not be as desirable as that
shown in FIG. 5, where the cover 50 cannot be viewed until the
package 1 is opened.
[0148] The package 1 of FIG. 5 has been described above with
respect to top, bottom, back and front face walls 2, 3, 6, 7 of the
package 1. The cover 50 could, however, be provided for other types
of package 1 than that shown in FIG. 5. Thus, any package that
opens in three faces about a hinge provided in the fourth face of
the package 1 to reveal tissues in the three faces could desirably
include a cover for one, two or three of the faces to provide dust
protection for the tissue of the package. Such a cover is attached
on a part of the package 1 on one side of the opening and is
slidable with respect to a part of the package on the other side of
the opening and preferably is attached on an inside of the package
so that the package covers the cover when the package is in a
closed configuration. Preferably, the dispensing opening revealed
by a face of the package opposing the hinge face is not covered or
is only partially covered by the cover so that a user is not
hindered from grasping the underlying tissues through the
dispensing opening. More preferably, the cover is disposed with
respect to, preferably only with respect to, covering one or both
of the faces of the stack that extend between a hinge face of the
package and a dispensing opening.
[0149] Referring to FIG. 6, an interfolding pattern for the stack
of tissues 10 in the package 1 can be seen. The stack of tissues 10
comprises a first tissue 45, a second tissue 46 and a sequence of
further tissues until the last tissue 47 that are interfolded to
form the stack of tissues 10. For any given tissue in the stack 10
(except for the first and last tissues 45, 47 in the tissue
withdrawal sequence of the stack 10), the given tissue 46 is folded
so as to provide a leading panel 46' and a trailing panel 46''
connected by a fold 46''. The given tissue 46 is elongate and the
fold 46'' extends laterally across the given tissue 46. The leading
panel 46' is in partial face-to-face relation (along a partial
longitudinal extent of the leading panel in the longitudinal
direction of the tissue 46) with a trailing panel of a previous
tissue 45 in the tissue withdrawal sequence of the stack 10.
Further, a trailing panel of the given tissue 46 is in partial
overlapping face-to-face relation with a leading panel of a next
tissue in the tissue withdrawal tissue. In this way, as the tissue
45 previous to the given tissue 46 is withdrawn, the tissue 46
travels with it in the tissue withdrawal direction as a result of a
trailing panel of the previous tissue 45 being in face-to-face
overlapping relation with a leading panel of the given tissue 46.
Likewise as the given tissue 46 is withdrawn, the next tissue 48
travels with it as a result of a leading panel of the next tissue
being in face-to-face overlapping relation with a trailing panel of
the given tissue 46.
[0150] Referring to FIG. 6, the leading panel 46' of the given
tissue 46 overlaps with a trailing panel of the previous tissue 45
in the tissue withdrawal sequence to a partial extent along a
longitudinal axis of the given tissue 46. Likewise, a trailing
panel 46'' of the given tissue 46 overlaps partially with a leading
panel of the next tissue 48 in the tissue withdrawal sequence to a
partial extent along a longitudinal axis of the given tissue 46.
There is thus provided an elongate stack 10 having a central
portion 60 between opposed longitudinal end portions 61 where the
leading and trailing panels of the tissues in the stack 10 overlap
with one another in face-to-face relation. At the opposed
longitudinal ends 61 of the stack 10, adjacent tissues in the stack
10 do not overlap with one another. Thus, for the given tissue 46,
there is a leading panel 46' overlapping with a trailing panel of a
previous tissue 45 in the tissue withdrawal sequence along a first
portion of the leading panel 46'. Likewise, the trailing panel 46''
overlaps in face-to-face relation with a leading panel of a next
tissue 48 in the tissue withdrawal sequence of the stack 10 along a
second partial extent of the trailing panel 46'' in a longitudinal
direction of the tissue 46. There is thus first and second
longitudinal portions of the given tissue 46, which are separated
by the fold 46''' that do not overlap with adjacent tissues in the
tissue withdrawal sequence that. The overlapping portions of the
tissues in the stack 10 correspond to the overlapping portion 60 of
the stack, while the non-overlapping portions of the tissues in the
stack 10 correspond to the non-overlapping portions of the stack 10
at opposed longitudinal ends 61 of the stack 10.
[0151] In a longitudinal direction of the elongate stack 10, a
ratio of a longitudinal extent of the overlapping portion 60 to a
longitudinal extent of the stack 10 is about 30%.
[0152] The overlapping region 60 of the stack 10 is a central
region between opposed longitudinal portions 61 of the elongate
stack 10. The package 1 is configured so that a dispensing opening
11, and the perforation line 8 that has to be broken to create the
dispensing opening, is disposed in the central region of the stack
10. The weight of the stack 10 is thus centrally biased in the
overlapping region 61 so that the overlapping region 60 weighs more
than either of opposed non-overlapping longitudinal end portions 61
of the stack 10 when a longitudinal axis of the stack 10 is aligned
horizontally.
[0153] In use, with respect to any given tissue 46 in the stack 10,
as the previous tissue in the tissue stacking sequence 45 is
withdrawn through the dispensing opening 11 (as described
previously) of the package 1, the slack provided by the
longitudinal extent of the next tissue 45 that does not overlap
with the second tissue 46 is taken up. Once the slack is taken up,
and the next tissue 45 is withdrawn through the dispensing opening
11 to a major longitudinal extent of the tissue 45, tension along
the tissue withdrawal direction of the next tissue 45 is
transferred to the given tissue 46 by way of the face-to-face
interaction between a portion of the trailing panel of the next
tissue 45 and a portion of the leading panel 46' of the given
tissue 46. Once the tissue 45 is withdrawn through the dispensing
opening so that the full longitudinal extent of the overlapping
portion of the leading panel of the given tissue 46 protrudes
through the dispensing opening 11, the next tissue 45 is released
from the given tissue 46 and is dispensed from the stack 10 and the
package 1. The given tissue 46 that protrudes through the
dispensing opening 11 may then be grasped by a user for dispensing.
The slack in the given tissue 46 where it is not in overlapping
face-to-face relation with the next tissue 48 in the tissue
withdrawing sequence can be taken up until it reaches an
overlapping portion between a face of the trailing panel 46'' and a
face of a portion of a leading panel of the next tissue 48. At this
point, pulling on the given tissue 46 causes the next tissue 48 to
travel with it because of the face-to-face interaction between the
given tissue and the next tissue 48 at the overlapping portion
thereof. This procedure is repeated in order to dispense any given
tissue in the stack 10.
[0154] The stack of tissues 10 can be an independent aspect of the
present invention. Thus, the stack 10 can be provided in an
alternative type of container to the disposable package 1, such as
one made of more hardwearing materials like metal or rigid plastics
as in a wall mountable container. In such a wall mountable
container, the container is preferably elongate so that its
longitudinal axis coincides with a longitudinal axis of the stack
10. Further, a dispensing opening of the container is preferably
longitudinally centrally positioned in the container and extends
laterally across the container as with the package 1 described with
respect to FIG. 6. The dispensing opening preferably extends
laterally across the container from one face to an opposing face so
as to present a dispensing opening of the container that is at
least as laterally large, if not larger than, a lateral extent of
the stack 10. This configuration means that the stack 10 will tend
to bulge into the dispensing opening in the tissue withdrawal
direction when the tissue withdrawal direction is aligned with
gravity (that is, the longitudinal axis of the stack 10 and the
container are aligned with the horizontal).
[0155] The stack may be made up of multiply folded sheets, rather
than the single fold shown. In this case, any given sheet will
overlap with adjacent sheets along a partial extent of its leading
and trailing panels. There will also be at least one intermediate
panel between the leading and trailing parts. Further, the sheets
of the stack may include a perforation line connecting adjacent
panels of the sheet so that the sheet can be divided into at least
two pieces at one or more perforation lines connecting panels.
[0156] A ratio of an extent of a longitudinal extent of the
overlapping region 60 of the stack 10 to a longitudinal extent of
the stack 10 as a whole has been described above as being about
0.3. The ratio is preferably as outlined above in the summary
section, which may preferably be 0.25 to 0.5.
[0157] FIG. 7 discloses a preferred embodiment of a moist non-woven
sheet dispenser 70. The moist non-woven sheet dispenser 70 is in an
open configuration in FIG. 7a and is in a closed configuration in
FIG. 7b. The moist non-woven sheet dispenser has a receptacle 71
for receiving a stack of moist non-woven sheets. The receptacle has
first and second opposed major faces, first and second opposed
minor faces and first and second intermediate sized opposed faces.
The major faces are provided by top and bottom wall faces 72, 73,
the minor faces are provided by opposed end wall faces 74, 75 and
the intermediate sized faces are provided opposed front and back
faces 76, 77. The top wall face 72 is characterised by having a
dispensing opening 78 in a central region thereof. The front face
76 is characterised by having a recess and catch 79 formed therein
for receiving a tab 80 of a lid 81 therein in order to secure the
lid in the closed configuration of FIG. 7b. The back face wall 77
is characterised by having a hinge member 82 extending therefrom so
as to hingedly connect a lid 81 to the receptacle 71. The opposed
end face walls 74, 75 and the opposed front and back face walls 76,
77 depend from the top face wall 72 and partially define a moist
non-woven sheet receiving cavity of the receptacle 77. A bottom
face of the receptacle 77, as defined by the end face walls 74, 75
and the front and back face walls 76, 77, is open so that tissues
can be inserted into the receptacle 77 through its open bottom face
73.
[0158] The moist non-woven sheet dispenser has a bottom part 83
that is removably fittable in the open bottom face of the
receptacle 71. The bottom part 83 is shown removed from the
receptacle 71 in FIG. 7c and attached to the receptacle 71 in FIGS.
7a and 7b. The bottom part 83 provides an upstanding platform 84
surrounded by a peripheral flange 85. The platform 84 is sized so
as to be fittingly received by the inside of the opposed end walls
74, 75 and the front and back walls 76, 77. A top surface 86 of the
platform 84 provides a base of the receptacle 71 upon which a stack
of moist non-woven sheets can lay. Depending from the platform 84
of the bottom part 83 is a triangular prism shaped part 87, which
defines a standing surface for the moist non-woven sheet dispenser
70.
[0159] The moist non-woven sheet dispenser 70 further comprises a
lid 81 that is hingedly connected to the receptacle 71 by way of
the hinge member 72. The lid 81 is movable by pivoting about the
hinge member 82 between opened and closed configurations. The lid
81 defines about its periphery a depending flange that fits over
and outside of an upstanding flange 89 extending about a periphery
of the top surface 72 of the receptacle 77. The depending flange 88
of the lid 81 and the upstanding flange 89 extending about the
periphery of the top surface 72 of the receptacle 71 sealingly
engage with one another, with the depending flange 88 of the lid 81
being positioned peripherally outside the upstanding flange 89 of
the receptacle 71. Referring to FIG. 7b, the top surface 90 of the
moist non-woven sheet dispenser is smooth and continuous for easy
wiping.
[0160] The dispensing opening 78 of the top surface 72 of the
receptacle 71 is partially closed by an insert 91 that extends
around the dispensing opening and has inwardly protruding flaps 92
separated by slits 93. The flaps are circumferentially distributed
about a central hole through which the tissue passes in exiting the
dispensing opening 78 and the insert 91.
[0161] To use, the lid 81 is grasped by a thumb inserted into the
recess of the catch and recess 79 when the moist non-woven sheet
dispenser 70 is in the closed configuration. The thumb thus pulls
the lid 81 so as to rotate about the hinge member 82, which causes
the tab 80 to deform away from a catch at the top of the catch and
recess 79 to thereby release the lid 81 for movement into the
opened configuration as shown in FIG. 7a. Opening the moist
non-woven sheet dispenser 70 reveals the top surface 72 and a
dispensing opening 78. A moist non-woven sheet can be withdrawn
from the receptacle 77 through the dispensing opening 78 in the top
surface 72 of the receptacle 71 and through the insert 91 that
partially closes the dispensing opening 78. As a tissue is pulled
through the insert 91, the flaps 92 deform in the tissue withdrawal
direction, which serves to scrunch the moist non-woven sheet as it
is being withdrawn, which may allow any excess moisture on the
tissue to be squeezed off and kept inside the receptacle 71. After
a tissue has been withdrawn, the lid 81 can be closed again so that
the tab 80 is deformed outwardly to allow it to pass over a catch
and then resiliently reforms inwardly so as to be received in the
recess of the catch and recess 79. In the closed configuration, the
depending peripheral flange 88 of the lid 81 sealingly mates with
an upstanding peripheral flange 89 of the receptacle 71. These
flanges may be at least partly formed of a resilient or rubber-like
material in order to improve the sealing capabilities. Likewise,
the insert 91 can be made of a rubber-like material to allow the
flaps 92 to resiliently reform and also for sealing the dispensing
opening 78.
[0162] When a replacement stack of moist non-woven sheets is to be
inserted in the receptacle 71 of the moist non-woven sheet
dispenser 70, the bottom part 83 is removed so that the platform 84
comes out of engagement with the front, back and end face walls 76,
77, 74 and 75 of the receptacle 71. The receptacle 71 can then be
turned over so that the cavity defined by the walls of the
receptacles 71 faces upwards. A stack of moist non-woven sheets can
then be inserted into the cavity defined by the receptacle 71 and
the bottom part 83 can be inserted so that it sealingly mates with
the front, back and end face walls 76, 77, 74 and 75 of the
receptacle 71. A top face 86 of the platform 84 is thus in
face-to-face relation with a bottom tissue of the stack of moist
non-woven sheets inserted in the receptacle 71. The moist non-woven
sheet dispenser 70 can then be turned back around so that the lid
81 and the dispensing opening 78 is faced upwards. In inserting the
bottom part 83, the platform 84 may be slightly compressed by the
walls of the receptacle 71 as it is inserted so as to ensure a fast
engagement between the bottom part 83 and the walls of the
receptacle 71, which is also a sealing engagement. Thus, the bottom
part 83 is made of a resilient material. The bottom part 83 may be
made of a rubber or rubber-like material.
[0163] In the closed configuration shown in FIG. 7b, the moist
non-woven sheet dispenser 70 is substantially sealed and thus
prevents escape of moisture from the dispenser 70. The sealingly
mating flanges 88, 89 of the lid 81 and receptacle 71,
respectively, prevent any moisture from escaping along a path
through the dispensing opening 78, in a gap between the lid 81 and
the receptacle and the top surface 72 of the receptacle 71 and thus
out of the moist non-woven sheet dispenser 70. Further, the sealing
engagement between the bottom part 83 and the depending walls 74,
75, 76 and 77 of the receptacle 71 prevents any moisture from
escaping from the open bottom face of the receptacle 71.
[0164] In the shown embodiment, the bottom part 83 provides a
standing surface of the moist non-woven sheet dispenser 70 that is
not flat relative to the lid 90. Instead, it defines depending
sloped surfaces that meet at a central point. Such bottom surfaces
have a function that will become clear in the following. The moist
non-woven sheet dispenser 70 could be made so as to have a flat
bottom surface in order to allow it to stand on a counter top so
that the plane of the top surface 72 and the plane of the lid 90
presents a substantially flat surface (relative to the counter top)
that faces upwardly to a user.
[0165] The insert 91 is provided in the form of a flap 92 and slit
93 structure where the flaps define a circumference of a 3 0
central opening through which moist non-woven sheet can be
withdrawn. Other types of resilient inserts 91 are known in the
art. The insert 91 could be modified so as to define just one slit,
which could be straight or wavelike. Similarly, the closing
mechanism, which is a tab 80 and catch and recess structure in the
shown embodiment, could be any known type of closure mechanism. For
example, the receptacle 71 could define a protruding tab in a front
face 76 and the lid 81 could have a mating lip that can be
resiliently deformed outwardly to pass over the tab and when
released resiliently reforms so that the lip catches onto the tab
to thereby secure the moist non-woven sheet dispenser 70 in the
closed configuration.
[0166] FIG. 8 discloses a moist and dry tissue dispensing system 90
comprising a dry tissue dispenser 20 and a moist non-woven sheet
dispenser 70. The dry tissue dispenser is as described above with
respect to FIG. 2. The moist non-woven sheet dispenser 70 is as
described above with respect to FIG. 7. The moist non-woven sheet
dispenser 70 carries a stack of moist non-woven sheet in the
receptacle 71 thereof. The dry tissue dispenser 20 carries a
package 1 comprising a stack of dry tissues 10. The dry tissue
dispenser 20 is adapted to be mounted to a room wall by way of a
back plate 22. The peripheral wall extending from the rear plate 22
in a direction of a normal to the plane defined by the rear plate
22 has a bottom face part 26 and a top face part 25. The bottom
face part 26 is characterised by having a dispensing opening 24
through which a dispensing opening 11 of the package 1 can be
accessed so that dry tissues in the package 1 can be withdrawn. The
top face part 25 of the dry tissue dispenser 20 defines a depending
V-shape in an outer surface thereof. The moist non-woven sheet
dispenser 70 has the bottom part 83 that also defines a V-shaped
recess as a bottom outer surface. The V-shape of the bottom part 83
of the moist non-woven sheet dispenser 70 and the top part 75 of
the dry tissue dispenser 20 substantially fit with one another so
that the moist non-woven sheet dispenser 70 is securely received by
the dry tissue dispenser 20. The moist non woven sheet dispenser 70
sits atop the dry tissue dispenser 20 and they have cooperating
interfacing surfaces, which prevent relative movement of the moist
non-woven sheet dispenser 70 along an axis extending between
opposing end face walls 27, 28 of the dry tissue dispenser and end
face walls 74, 75 of the moist non-woven sheet dispenser.
[0167] In use, the dry tissue dispenser is mounted to a room wall
so that the rear plate 22 is mounted against the room wall. A
normal direction to the room wall and to the rear plate 22 can be
defined as a Z direction. The moist non-woven sheet dispenser 70
can then be placed on top of the dry tissue dispenser 20 so as to
provide a moist and dry tissue dispensing system 90. A package of
dry tissues 1 is inserted through an open front face of the dry
tissue dispenser 20, as described previously with respect to FIG.
2. The lid 81 of the moist non-woven sheet dispenser 70 can be
opened as shown in FIG. 7a so as to reveal the dispensing opening
78. A user can withdraw tissue from the dispensing opening 78 of
the moist non-woven sheet dispenser 70 and can withdraw dry tissue
through the dispensing opening 11 of the package 1 and the
dispensing opening 24 of the dry tissue dispenser 20, as needed.
The moist and dry tissues are dispensed in opposing tissue
withdrawal directions, which can be considered to lie along a
Y-axis perpendicular to the Z-axis. An X-axis can also be defined
that is perpendicular to the Y axis and the Z-axis and extends in a
direction between opposing end face walls 27, 28 of the dry tissue
dispenser 20 and between opposing end face walls 74, 75 of the
moist non-woven sheet dispenser 70. The depending sloped surfaces
at the bottom of the moist non-woven sheet dispenser and the
depending slopes surfaces of the top surface of the dry tissue
dispenser 20 matingly interact so that the sloped surfaces of the
dry tissue dispenser 20 resist movement of the moist non-woven
sheet dispenser 70 in the X-direction.
[0168] The dry tissue dispenser 20 can be easily refilled by
replacing the package 1 therein with a fresh package through an
open front face of the dry tissue dispenser 20. The moist non-woven
sheet dispenser can be easily refilled by tipping it up and
removing the bottom part 83 from the receptacle 71 and inserting a
new stack of moist non-woven sheets in the open face presented by
the upturned receptacle 71 of the moist non-woven sheet dispenser
70. The bottom part 83 can then be replaced and the moist non-woven
sheet dispenser 70 repositioned back on top of the dry tissue
dispenser 20. The depending nature of the bottom part 83 means that
the moist non-woven sheet dispenser 70 has a centre of gravity
positioned within the bottom part 83 and preferably also within an
X-directional line connecting opposing sloping surfaces of the top
part 25 of the dry tissue dispenser 20. This provides a
particularly stable configuration for the moist non-woven sheet
dispenser 70 which preferably allows a user to withdraw moist
non-woven sheets from the moist non-woven sheet dispenser 70 using
only one hand. That is, the moist non-woven sheet dispenser 70 is
not required to be stabilised with one hand so that moist non-woven
sheets can be withdrawn from the moist non-woven sheet dispenser 70
with the other hand.
[0169] In a modification of the dry tissue dispenser 20 shown in
FIGS. 8a and 8b, there may also be provided front and back
upstanding flanges that contact front and back faces 76, 77 of the
moist non-woven sheet dispenser 70 so as to resist movement of the
moist non-woven sheet dispenser 70 in the Z-direction when tissue
is being withdrawn from the moist non-woven sheet dispenser 70.
Similarly, upstanding flanges can be positioned at opposed end
plates 27, 28 of the dry tissue dispenser so as to contact end
faces 74, 75 of the moist non-woven sheet dispenser. Preferably,
upstanding flanges extend about a periphery of a top face part 25
of the dry tissue dispenser 20, which will thus surround front,
back and end face walls 76, 77, 74 and 75 of the moist non-woven
sheet dispenser to keep the moist non-woven sheet dispenser 70 in
position in the X and Z directions when tissue is being dispensed
from the moist non-woven sheet dispenser 70. As with the
cooperating interfacing surfaces shown in FIGS. 8a and 8b, such
upstanding flanges do not hinder movement of the moist non-woven
sheet dispenser 70 in the Y direction for when the moist non-woven
sheet dispenser 70 has to be refilled.
[0170] The moist non-woven sheet dispenser 70 may have a bottom
surface that does not define a depending v-shape such as a flat
surface. It may be provided with means for securing it to a room
surface such as a counter top. The means could be suction cup
means, for example. In this case, the cooperating interfacing
surfaces between the moist and dry dispensers 20, 70 are not
necessarily required, although they are preferred. Alternatively,
there could be a magnetic interaction to secure the moist and dry
dispensers 20, 70 together. These alternative securement means
(magnetic/suction cup/otherwise) do not have the aesthetic
advantage of the male/female interfitting bottom and top surfaces
of the moist and dry sheet dispensers 20, 70 of the system 90 of
FIG. 8.
[0171] The dry tissue paper of all aspects of the present invention
is preferably toilet paper, which is characteristic over other
kinds of hygiene tissue paper, such as facial tissue paper, as
known by the skilled person. It may be embossed, and it may be
single-ply or multiply. One characteristic feature of braided paper
as compared to other types of hygiene or absorbent paper is its
dissolvability. Toilet paper has a characteristic bowl or shortly
after flushing. Other types of tissue paper include wet strength
agents to reduce their water dissolvability.
[0172] In a preferred embodiment, the feature described above
relating to the breakable package of FIG. 1, the dispenser of FIG.
1, the overlapping lips of the package of FIG. 5, the interfolding
arrangement of FIG. 6 and the moist non-woven sheet dispenser of
FIG. 7 are combined in a system as shown in FIG. 8.
[0173] The scope of the absorbent tissue paper systems of the
present invention is defined in the following claims.
