Description
FIELD OF THE INVENTION
[0001] The present invention is concerned with a dispenser for
holding and containing a stack of absorbent products such as paper
sheets. The paper sheets may be any non-woven absorbent or hygiene
material that is paper based. The percentage of paper fibres in the
sheet can vary so that only a minor portion of the non-woven may be
paper fibres. This is true of some moist wipes, whereby paper
fibres are mixed with a large percentage of polymer fibres. The
paper sheets may be paper towels, napkins, facial tissue, moist/wet
wipes, toilet paper, etc. The absorbent products may be absorbent
garments such as diapers (or incontinence garments), absorbent pads
such as sanitary towels or pant-liners.
BACKGROUND TO THE INVENTION
[0002] It is known in the art to provide a box for holding and
containing a stack of paper sheets. The box will have a dispensing
opening through which the sheets are dispensable from the stack and
the box. Commonly, for facial tissue products, sheets are stacked
in the box and the box is designed so that the sheets lay stacked
upon one another with the weight of the stack resting on a bottom
sheet of the stack, wherein the bottom sheet is adjacent a bottom
face of the box. The dispensing opening is provided, usually
centrally, on a top face of the box adjacent a top sheet of the
stack. Typically, the sheets are interfolded so that as one sheet
is dispensed, it pulls part of the next sheet through the
dispensing opening to give so called `pop-up` dispensing. `Pop-up`
dispensing makes it easy to locate the next tissue for dispensing
as it sticks out of the box, as compared to having to reach into
the box through the dispensing opening to grab a sheet. Doing such
would be particularly fiddly as the stack becomes depleted as the
top sheet would be spaced away from the dispensing opening toward a
bottom of the box. `Pop-up` dispensing is effective for ensuring
that a first sheet in the stack is easy to grasp. There are,
however, disadvantages to the technique. The depth of the box is
limited to a length of the sheets minus the overlap margin between
adjacent tissues, which may be an undesirable design constraint in
some applications. Further, some paper sheet materials do not lend
themselves to interfolding, so pop-up sheet dispensers are not
always a viable option.
[0003] There is also known a tissue box whereby the stack rests on
the bottom of the box on an edge of the sheets in the stack. That
is, planar faces of the first and last sheets in the stack are
located adjacent front and back faces of the box, while bottom
edges of each sheet are located adjacent a bottom face of the box
with respect to gravity so that the weight of the stack rests on
those bottom edges. Such boxes may be wall mountable in that a top
of the box can be hung from a support member (e.g. a towel bar)
such as those made for being received in a hollow core of, say, a
roll of kitchen towels. A dispensing opening may be positioned at
the bottom of the front face of the box.
[0004] An example of an edge stacked paper sheet dispenser is the
packaged absorbent paper product of US 2002/0092789. It can occur
in such a paper product dispenser that, when the stack becomes
depleted, the stack moves to the back of the dispenser, away from
the front of the dispensing opening. If that occurs, a user may
struggle to reach the paper sheets. In view of such an issue, US
2002/0092789 discloses one version of the packaged absorbent
product dispenser that is in the shape of a three dimensional
parallelogram so that a bottom face is angled downwardly from a
back face to a front face, which feeds the paper sheets to the
dispensing opening as the stack is depleted. This helps to
eliminate the need to reach into the dispenser when there is a
missed interfold or dispensing problem. The parallelogram design of
US 2002/0092789 may not always work as it is intended. That is, the
depleted stack could take on a profile, whereby these sheets are
not fed to the dispensing opening and thus still get stuck at the
back of the dispenser.
[0005] U.S. Pat. No. 5,102,007 and US 2002/0108962 disclose other
mechanisms for positioning a depleted stack towards the dispensing
opening. U.S. Pat. No. 5,102,007 discloses a rotatable blocking
member that is biased toward a blocking position. The blocking
member moves to the blocking position under the bias once the stack
is depleted to a predetermined extent. In the blocking position,
the stack is blocked from moving away from the dispensing opening
by a user applying an upward force to the bottom sheet of the stack
in trying to withdraw a sheet through the dispensing opening. US
2002/0108962 discloses a sheet dispensing aid in the form of a
spring that pushes the sheets forward towards the dispensing
opening. The biased blocking member and the spring dispensing aid
of these prior art documents are not inexpensive to manufacture.
Accordingly, they may be more suitable for implementation in a
permanent, refillable dispenser, rather than a disposable one that
is inexpensively made and designed to be disposed of once the stack
is used up.
[0006] Accordingly it is an object of the present disclosure to
provide a dispenser for dispensing a stack of absorbent products
such as paper sheets that is relatively inexpensive to manufacture
and includes a means for moving the stack toward a dispensing
opening of the dispenser when the stack becomes depleted.
[0007] In one aspect of the present disclosure, there is provided a
dispenser for containing and holding a stack of absorbent products
such as paper sheets located inside the dispenser, the dispenser
comprising a dispensing opening through which the products are
dispensable, wherein the dispenser comprises a manually graspable
member that is graspable by a user from outside the dispenser and
manipulatable by the user to move the stack when it is in a
depleted state from a retracted position relative to the dispensing
opening to a position adjacent to the dispensing opening.
[0008] A dispenser according to the present disclosure includes a
manually graspable member protruding to outside of the dispenser,
which can be pulled upon by a user to move the stack toward the
dispensing opening where the products may be easily grasped and
dispensed, as compared to the retracted position where the products
are spaced from the dispensing opening and can not be easily
reached. It is under manual force from the user that the stack is
moved toward the dispensing opening, which is in contrast to the
spring mechanisms of the prior art discussed above. Accordingly,
the stack moving means of the present disclosure may be relatively
inexpensively manufactured. Further, the stack is movable from the
retracted position whenever it is deemed to be necessary at the
behest of the user by manipulating the manually graspable
member.
[0009] In an embodiment, the dispenser comprises a stack moving
member for engaging the stack, wherein the manually graspable
member is manipulatable to reconfigure the stack moving member to
thereby move the stack from the retracted position to the position
adjacent the dispensing opening when the stack is in the depleted
state.
[0010] Thus, the manually graspable member and the stack moving
member are operatively associated with one another. The former
being positioned outside of the dispenser for operation by a user
and the latter being positioned inside the dispenser to operate on,
and in engagement with, the stack to affect a stack moving
operation.
[0011] In an embodiment, the manually graspable member is arranged
to protrude out of the dispensing opening to allow it to be grasped
by a user.
[0012] The manually graspable member thus extends from inside the
dispenser to outside the dispenser in order to allow it to operate
with the stack inside the dispenser and the dispensing opening
provides a convenient opening through the dispenser to use for the
manually graspable member to protrude through. It is envisioned
that a separate opening may be provided through which the manually
graspable member can extend. For example, a dedicated slot could be
provided, perhaps in the same face as the dispensing opening, out
of which the manually graspable member can protrude.
[0013] In an embodiment, the stack moving member is arranged to
protrude out of the dispenser to provide the manually graspable
member.
[0014] This is a simple, yet effective, way to operatively
associate the stack moving member and the manually graspable
member, specifically by making them integral members. The manually
graspable part of the stack moving member is manipulatable from
outside the box to cause the stack engaging part to move the stack
toward the dispensing opening so that a product can be easily
reached. One can, however, imagine other implementations such as
one where a separate manually graspable member is positioned
outside the box and is attached to the stack moving member by
extending through a wall of the dispenser. The manually graspable
member preferably protrudes through the dispenser on the same face
of the dispenser as the face where the dispensing opening is
located. One can, however, imagine an alternative implementation
where the manually graspable member protrudes through a side face
relative to a front face where the dispensing opening is located.
Such a manually graspable member would still be operable on the
stack moving member to move the stack from a retracted position to
a forward position adjacent the dispensing opening.
[0015] In an embodiment, the stack moving member is for engaging a
face of the stack opposed to a face of the stack that is positioned
adjacent to the dispensing opening.
[0016] In this embodiment, the stack moving member is shaped to
have a part positioned behind the stack relative to the dispensing
opening, which ensures the stack will be moved forward when a force
is applied to the stack moving member by way of the manually
graspable member in a direction toward the dispensing opening.
[0017] In an embodiment, the stack moving member is shaped to
cradle the stack when the stack is in the retracted position so as
to engage a face of the stack opposed to a face of the stack
adjacent the dispensing opening and a side of the stack connecting
the opposed faces.
[0018] In this way, the stack moving member securely engages faces
of the stack transverse to one another by taking on an L shaped
profile. This cradling effect is able to grip the stack to allow
controlled movement thereof when the manually graspable member is
manipulated.
[0019] In a second aspect of the present disclosure, there is
provided a dispenser for holding and dispensing a stack of
absorbent products such as paper sheets, the dispenser comprising a
dispensing opening through which products in the stack are
dispensable, wherein the dispenser comprises a stack moving member
having a first configuration conforming to faces of the dispenser
that are transverse to one another and a second configuration
forming a ramp between those faces of the dispenser and extending
towards the dispensing opening, wherein the stack moving member is
reconfigurable from the first configuration to the second
configuration to thereby move the stack when it is in a depleted
state from a retracted position relative to the dispensing opening
to a position adjacent to the dispensing opening.
[0020] The dispenser of the second aspect of the present disclosure
allows the stack to substantially fill the dispenser when the stack
is in a full state because it conforms to the faces of the
dispenser, thereby not taking up space. In the second
configuration, a depleted stack is moved toward the dispensing
opening by being tilted in the dispenser by the ramp. The ramp
further provides a configuration down which the stack can slide to
position a product for dispensing conveniently adjacent the
dispensing opening.
[0021] This form of reconfiguring of the stack moving member to a
ramped shape from a shape conforming to the walls of the dispenser
is preferably applied to the first aspect of the disclosure. One
can, however, imagine an implementation whereby the stack moving
member remains in the shape it has when it conforms to the inner
walls of the dispensing opening and is simply moved toward the
dispensing opening in that shape to move the stack to the position
adjacent the dispensing opening.
[0022] In an embodiment, the stack moving member is fixed at a
point relative to the dispenser so that at least part of the stack
moving member rotates about the fixed point in reconfiguring from
the first configuration to the second configuration.
[0023] Thus, pulling on the manually graspable member causes the
stack moving member to rotate about the fixed point to form the
ramp.
[0024] Preferably, a blocking member is provided to prevent upward
movement of the stack moving member, where upward is to be
interpreted in the context of the direction of movement the stack
moving member makes in rotating to the second configuration. The
blocking member acts to prevent upward movement as the stack moving
member runs from inside the dispenser to outside the dispenser in
reconfiguring the stack moving member from the first configuration
to the second configuration. In an embodiment, the blocking member
is located at a junction between inside and outside of the
dispenser. These features ensure that the stack moving member is
pulled outward and perhaps a little downward, in moving the stack
toward the dispensing opening. It could happen, particularly in the
embodiment rotatable about the fixed point, that the stack moving
member is moved upward and away from the dispensing opening, which
would not facilitate a sheet being conveniently grasped through the
dispensing opening. To ensure proper forward movement of the stack,
the blocking member is provided.
[0025] In an embodiment, the stack moving member is bent to conform
to first and second faces of the dispenser when it is in the first
configuration, wherein the first and second faces of the dispenser
extend substantially transversely to one another, and the bend is
straightened in order to form a ramp between the first and second
faces that extends toward the dispensing opening in the second
configuration of the stack moving member.
[0026] In this embodiment, the stack moving member is reconfigured
from a space saving configuration where it is in conformity with
the faces of the dispenser to allow the dispenser to be filled to a
configuration forcing the sheets adjacent the dispensing opening
for easy access thereto.
[0027] In an embodiment, the stack moving member is moveable
relative to the dispensing opening. This feature enables the stack
moving member to pull the stack closer to the dispensing
opening.
[0028] In an embodiment, the stack moving member is sized and
shaped to be able to close the dispensing opening when the stack
moving member is in the first configuration and the second
configuration. That is, the stack moving member may protrude out of
the dispenser to form a flap, which may also provide the manually
graspable member, that is positionable to close the dispensing
opening.
[0029] In an embodiment, the stack moving member is sized and
shaped to cover, at least substantially, the entire dispensing
opening when the stack moving member is in the first configuration
and the second configuration. Thus, the stack moving member may
serve the dual function of being configurable to move the stack
from a retracted position to a forward position when it is depleted
and also to entirely close the dispensing opening for hygiene
purposes. Further, because the stack moving member is so sized, it
protrudes from inside the dispenser where it engages the stack to
outside the dispenser where it provides both a cover and a manually
graspable member that is manipulatable to affect movement of the
stack from the retracted position to the forward position. That is,
it is the cover that can be manipulated by a user (e.g. pulled), in
order to bring the stack forward to the dispensing opening.
[0030] The stack moving member may thus include two folds, one
between first and second parts of the stack moving member
respectively conforming to the first and second faces of the
dispenser and one between the second part and a third part of the
stack moving member forming a cover member and manually graspable
member when the stack moving member is in the first configuration.
The folds provide hinges. The first hinge/fold allows the stack
moving member to be straightened to form the ramp and the second
hinge/fold allows the stack moving member to provide an openable
and closeable flap with respect to the dispensing opening.
[0031] In an embodiment, the dispenser comprises a releasable
attachment, preferably being repeatably releasable and
reattachable, of the stack moving member to the dispenser. This may
be in the form of adhesive tape, or the combination of adhesive
tape and a releasable film, or hook and loop attachment, a
cooperating push button and receptacle arrangement, a slide
fastener or other known means. The releasable attachment could
provide a border about the stack moving member for attachment about
at least a major portion of a periphery of the dispensing opening.
A slide fastener comprises as one mating component protruding lines
defining a channel between them and as a cooperating mating
component a protruding line for secure receipt in the channel. The
stack moving member may thus protrude from the dispenser, yet be
attachable to an outside surface to keep it neat. Further, the
releasable attachment may be used to keep the stack moving member
in a dispensing opening closing position for hygiene purposes. In a
disposable implementation of the dispenser, it may be wrapped with
a plastic film also for hygiene purposes.
[0032] Preferably, the dispenser is made, at least to a major
degree, of cardboard. This is an environmentally friendly, often,
but not necessarily, biodegradable material. Other materials can be
used. Thus, the dispenser of the present disclosure is preferably a
disposable one that is intended to be disposed of after the stack
is completely depleted. Refillable implementations are, however,
imagineable that would be made of more hardwearing materials than
cardboard. The dispenser may thus be made of plastic, wood or metal
at least to a major degree. The stack moving member (and the
manually graspable member) is preferably made of cardboard as well.
Other materials could be used, which may be biodegradable or less
biodegradable materials could also be used in view of the
relatively small size of the stack moving member. Alternative
materials for the stack moving member (and the manually graspable
member) are paper or plastic film.
[0033] In an embodiment, the dispenser comprises the stack of
absorbent sheets. The products may be diapers, incontinence diapers
or pads, panty liners, feminine towels, etc. In an embodiment, the
product claimed is a dispenser box in combination with a stack of
sheets. The sheets are preferably in the form of a kitchen paper
product for wiping up kitchen and other household spills. The
dispenser can hold and contain a stack of paper sheets of any kind,
as described above. The sheets may be separate in the stack or they
may be interfolded. The present disclosure is particularly useful
with separate sheets as they are more prone to becoming stuck at
the back of a dispenser as they do not have the pop out
functionality of interfolded sheets.
[0034] In an embodiment, the dispenser includes hanging structure
to enable the dispenser to be hung from a wall. It can be
advantageous to have a dispenser for tissues mountable to a wall
since it can then be lifted away from a counter top where the
dispenser and paper sheets may be prone to being wetted by counter
top spills. The hanging structure may be in the form of one or more
holes in a face of the dispenser opposed to a face encompassing the
dispensing opening. Alternatively, the hanging structure may be
structure to allow the dispenser to be hung from a bar, such as a
bar usually used to hang kitchen roll from. Any other known and
compatible means for hanging a paper sheet dispenser to a wall may
be utilised with the dispenser of the present disclosure.
[0035] The dispenser comprises a front face encompassing the
dispensing opening. The dispensing opening is preferably positioned
at one end of the front face, rather than being centrally located.
In this way, the dispenser can be hung from a wall with the
dispensing opening at a bottom of the front face. In an embodiment,
the front face is elongate, as is the dispenser itself, and the
dispensing opening is located at one longitudinal end of the front
face, which will thus be a bottom of the dispenser when the
dispenser is correctly hung from a wall with the top end of the
front face facing upwards.
BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0041] FIG. 1 shows a box shaped dispenser 1 comprising bottom and
top faces 2, 3, side faces 4, 5 and front and back faces 6, 7 (the
back face 7 can be seen in FIG. 5). The front face is characterised
by encompassing a dispensing opening 8. The dispensing opening is
located in the front face 6 at a position adjacent the bottom face
2. The back and top faces 7, 3 are respectively opposed to the
front and bottom faces 6, 7. The dispenser 1 is elongate in that a
direction from the bottom face to the top face 2, 3 is a
longitudinal direction, while a lateral direction extends from one
side 4 to the other side 5. The dispensing opening 8 is positioned
laterally centrally at the bottom of the front face 6.
[0042] There is a cover member 9 as shown in FIGS. 1 and 2 that is
used to open and close the dispensing opening 8. The cover member 9
is pivotable between the open and closed configurations, which can
respectively be seen in FIGS. 1 and 2. The cover member has
attached to it a piece of tape 10 to releasably attach the cover
member 10 in the closed position to a portion of the front face 6
just above the dispensing opening 8. The releasable adhesive of the
tape 10 is such as to allow the cover member 9 to be repeatedly
reattached to the front face 6, ideally for as many recursions as
there are sheets held in the dispenser. The cover member 9
substantially completely covers the dispensing opening 8 in the
closed position. This is enabled by a slot 11 that is continuous
with the dispensing opening 8, yet laterally longer than the
dispensing opening 8 on either side of the dispensing opening 8.
The cover member 9 can thus be made laterally longer than the
dispensing opening 8 to thereby cover the full lateral extent of
the dispensing 8, while still being able to extend from inside the
dispenser 1 to outside the dispenser 1.
[0043] The cover member 9 is referred to as a manually graspable
member in the summary section above and in the claims below. This
alternative terminology will also be used in the present
description depending upon the function being described. As will
become clear from FIGS. 3 and 4, the cover member 9 serves the dual
purpose of covering the paper sheets in the stack when it is in the
closed position and serving as a manually graspable member 9 that
is operable by a user to move the stack forward in the dispenser 1
when the cover member 9 is in the open position.
[0044] Referring to FIGS. 3 and 4, there can be seen a laterally
central, longitudinal cross-section of the dispenser 1 of FIG. 1,
which has been taken along the dotted line of FIG. 1. The dispenser
1 includes a stack moving member 12 in the form of a planar piece
that has been folded twice to provide three panels 12a, 12b, 12c. A
first panel 12a is attached to the inside of a back face 7 of the
dispenser 1 at a fixed point 13. When the stack moving member 12 is
in the retracted position shown in FIG. 3, the first panel 12a is
in face to face relation with the back face 7 of the dispenser 1
and extends so as to conform to the back face 7 of the dispenser 1.
When the stack moving member 12 is in the retracted position, the
second panel 12b is in face to face relation with the bottom face 2
of the dispenser 1 and extends so as to conform with the bottom
face 2. In the retracted configuration of the stack moving member
12, the first and second panels 12a, 12b extend transversely to one
another, with the first panel 12a extending longitudinally relative
to the dispenser 1 and the second panel 12b extending laterally
relative to the dispenser 1. The third panel 12c extends through
the slot 11 to extend outside of the dispenser 1 (relative to the
inside of the dispenser 1 for containing a stack of sheets) and
provides the manually graspable/cover member 9. The third panel 12c
is pivotable about a hinge 13 (FIG. 1) provided by the fold between
the second and third panels 12b, 12c from the open position of
FIGS. 1, 3 and 4 to the closed position of FIG. 2 to thereby
provide an openable and closeable cover member 9 as described
above.
[0045] When the cover member/manually graspable member 9 is pulled
upon from outside the dispenser 1 by a user, the stack moving
member 12 is moved from the retracted position of FIG. 3, where it
conforms to inside faces of the dispenser 1, to an extended
position as shown in FIG. 4. In the extended position, the first
and second panels are straightened with respect to the retracted
configuration when they have a transverse bend between them. The
stack moving member thus changes from a configuration conforming to
the inside faces 2, 7 of the dispenser 1 to a ramped configuration,
where the stack moving member 12 provides a ramp from a middle
portion of the back face 7 where the fixed point 13 is to the slot
11 adjacent the dispensing opening 8. The ramp provided by the
stack moving member provides a downward slope for a stack of paper
sheets 14 contained by the dispenser to slide down toward the
dispensing opening 8. It is not necessarily the downward slope that
is critical in getting the stack of paper sheets 14 adjacent the
dispensing opening 8 as compared to the retracted position of the
stack moving member 12. The stack of paper sheets 14 has a corner
that sits in a corner of the stack moving member 12 provided by the
fold between the first and second panels 12b, 12c. When the stack
moving member 12 is moved to the extended position of FIG. 4, its
corner is moved closer to the dispensing opening 8 as the stack
moving member 12 rotates about the fixed point 13 under force
exerted on the stack moving member 12 by a user grasping and
pulling on an end of the third panel 12c/cover member/manually
graspable member 9. The corner of the stack 14 will remain seated
in the corner of the stack moving member 12, thereby moving the
stack 14 closer to the dispensing opening 8. The first panel 12a
needs to be long enough and the fixed point positioned such that
the arc followed by the corner between the first and second panels
12a, 12b is sufficiently shallow (i.e. not too curved) that the
stack is able to move close enough to the dispensing opening 8 even
when the stack is almost completely depleted (i.e. just one or a
few sheets left). In the extended configuration of the stack moving
member 12 shown in FIG. 4, the part of the second panel 12b will
protrude through the slot 11, as well as the cover/manually
graspable member 9/third panel 12c.
[0046] In the full state shown in FIG. 3, the stack of paper sheets
14 is completely fills the dispenser 7 to such an extent that the
stack moving member panels 12a and 12b are forced by the stack 14
to conform to inside faces of the dispenser 1. The package 1 is
deep enough that a user can not reach a thumb and forefinger
through the dispensing opening 8 to grasp a tissue therebetween
when a sheet is faced against the rear face 7 of the dispenser 1,
hence the need for a stack moving member 12. A depleted stack 14 is
shown in FIG. 4 and is generally a quantity of paper sheets less
than when the dispenser 1 is full and that can not be conveniently
grasped by a thumb and forefinger through the dispensing opening 8
when the depleted stack 14 is faced against the rear face 7 of the
dispenser 1.
[0047] Referring to FIG. 5, the rear face 7 of the dispenser 1 can
be seen. The rear face 7 has positioned on it at least one (four in
the shown embodiment) adhesive strip 15 and at least one wall
(again, four) mounting hole 16. If a wall fastener such as a screw
is conveniently available, the wall mounting holes 16 can be used
to mount the dispenser 1 to the wall. Alternatively, the peelable
strips can be used to mount the dispenser to a wall.
[0048] The dispenser 1 is optimally made entirely, or at least to a
major extent, of cardboard, as this material is readily available,
is inexpensive, is often biodegradable and is able to be processed
with established know-how to make the dispenser 1.
[0049] In use, the dispenser 1 can be mounted to a wall via the
adhesive strips 15 or the mounting holes 16, usually at a location
in the kitchen that is conveniently accessible and position so that
the dispenser 1 is not in contact with a counter top. The dispenser
may, however, be used in a mode sitting on a counter top. In this
sense, the strips 15 and mounting holes 16 are optional. The
dispenser 1 is mounted so that the dispensing opening 8 located
downwardly. The dispensing opening is revealed by opening the cover
member 9 (which is provided by a third panel 12c of the stack
moving member 12) by peeling the tape 10 from the front face 6 of
the dispenser 1. A user withdraws a paper sheet from the stack 14
through the dispensing opening 8 in an outward motion (normal to
the wall) when the sheet is grasped by a user. The cover member 9
may hang down under gravity, allowing the user to remove a paper
sheet in a downward and outward motion. The dispensing opening 8
(including the slot 11) is preferably coterminous with the bottom
of the front face 6 (where it meets the bottom face 2) so that
there is not any intervening front face 6 material getting in the
way of a sheet being pulled downwards. After a user has withdrawn a
required number of sheets, the cover 9 is closed over the
dispensing opening 8 to protect the stack 14 from dust and other
contaminants for hygiene reasons.
[0050] After, say, half of the sheets in the stack 14 have been
withdrawn, the user will no longer be able to conveniently withdraw
sheets through the dispensing opening 8 as they will be located at
the back of the dispenser 1, too far away from the dispensing
opening to conveniently reach. The user can thus grasp the cover
member 9, which is thus being used as a manually graspable member
9, with the thumb and forefinger at a front edge portion thereof
and pull on it. In doing so, the stack moving member moves from the
bent configuration shown in FIG. 3 that conforms with inside back
and bottom faces 7, 2 of the dispenser 1 to a straightened
configuration as shown in FIG. 4 that ramps the stack 14 closer to
the dispensing opening. In going from the bent to the straightened
configuration, the stack moving member 12, and particularly the
fold between the first panel 12a and the second panel 12b rotate
about the fixed point 13 attaching the stack moving member 12 to
the back face 7, thereby moving the fold, and the back of the stack
14 sitting on it, closer to the dispensing opening 8. The depleted
stack 14 is thus moved to a position adjacent the dispensing
opening 8 from a retracted position to allow a user to conveniently
grasp a front sheet in the stack 14 and withdraw it through the
dispensing opening 8. The user can then close the dispensing
opening by pivoting the third panel 12c about the fold between the
second and third panels 12b, 12c to cover the dispensing opening 8
and adhere the tape 10 to the front face 6. Before closing the
dispensing opening, the user may move the stack moving member 12
back into the dispenser conforming configuration of FIG. 4 by
pushing on the front edge portion of the third panel 12c until the
fold between the first and second panels 12b, 12c again meets the
corner between the back face 7 and the bottom face 2 of the
dispenser 1.
[0051] There is a wall overhang of the front face 6 of the
dispenser 1 between the slot 11 and the dispensing opening 8. As
the stack moving member 12 is pulled out through slot 11, it runs
against the wall overhang, which thus prevents the stack moving
member from moving into the dispensing opening 8. Importantly, this
means that the stack moving member 12 is blocked from being moved
upwardly and thus the pulling direction of the cover member 9 is
required to be outwardly (and perhaps a little downwardly). Upward
movement could, in theory, not be effective in moving the sheets
closer to the dispensing opening 8.
[0052] Once the dispenser is completely out of sheets to dispenser,
the dispenser 1 can be dismounted from the wall and thrown away and
replaced with a new one.
[0053] A preferred embodiment has been described above. A number of
variations are envisageable, some of which are described in the
following.
[0054] The dispenser has been described as elongate in the bottom
to top direction. We can imagine a dispenser that is elongate in
the left side to right side direction, while a lateral axis of the
dispenser passes through top and bottom faces thereof. A dispensing
opening in such a box would still be provided at the bottom of a
front face of the dispenser along the lateral axis and it would be
positioned at a central location in the front face along the
longitudinal axis.
[0055] The slot and the dispensing opening do not have to be
continuous with one another. One can imagine a slot of similar
configuration to that shown in FIG. 2 that is spaced from the
dispensing opening and thus has a bridge of material of the front
face of the dispenser between them. This might not be as easy to
make as two holes would need to be made and it might not be as easy
to get the stack moving member threaded through such a small slot.
In the embodiment of FIG. 2 where the dispensing opening and slot
are continuous, the stack moving member can be laterally shortened
by bending to fit through the dispensing opening and then moved
down into position in the slot where it is able to reform to its
initial lateral extent.
[0056] The dispensing opening may be closed when it is first used
by a separate cover member that is integral with the front face but
tearable away therefrom by making use of a line of weakness. This
will be familiar to the skilled person from facial tissue boxes
where a dispensing opening is covered by a tear away cover member
that is defined in the face of the box with a line of weakness.
Such a design may be appealing as it offers security that the stack
of paper sheets is delivered in a hygienic state. In such an
embodiment, the manually graspable member can be delivered in a
position covering the tear away cover member as shown in FIG. 2.
Alternatively, the manually graspable member may be positioned
inside the dispenser and only moved outside for manual grasping
after the tear away cover member has been removed.
[0057] In an extension of the above design having a tear away cover
member, but which is also an independently applicable feature, the
stack moving member and the manually graspable member may be
thinner than the dispensing opening, perhaps provided in the form
of a strip. This would mean that it would not act as a cover
member, as it would be laterally too thin to cover the dispensing
opening. However, such a design may be advantageous as the reduced
extent may be aesthetically pleasing. Since it is not serving as a
cover member, it could also be made shorter so as not to protrude
as far out through the dispensing opening. If the manually
graspable member and stack moving member do not also have a cover
member function, then the slot is not a required feature since they
are thinner than the dispensing opening. This design may also make
it easier to wrap the stack moving member and manually graspable
member around a bottom edge of the stack so as to be easily located
inside the dispenser for storage and shipment and only be
protrudable outside of the dispenser once the dispenser has been
opened such as by tearing a cover member away as described
above.
[0058] Instead of, or in addition to, the wall mounting structure
shown in FIG. 5, the dispenser may be hangable from a bar such as
that used for rolling the core of a kitchen roll about. For
example, the top of the dispenser may be provided with a suitably
dimensioned hook. Alternatively, the top of the dispenser could be
provided with a flap attached to one of the front face and the back
face of the dispenser and removably attachable to the other of the
front and back face so that it can be threaded about the bar (as
shown in FIG. 1A of US 2002/0092789).
[0059] The holes for the wall mounting structure could be replaced
by a central hole, positioned toward a top of the dispenser, so
that only one wall fastener is needed to hang the dispenser from a
wall. The wall fastener could be any available wall hook, including
one already located on a user's wall. Thus, a dedicated or
specially wall is not required.
[0060] The stack moving member, the cover member and the manually
graspable member are in the shown embodiments all the same integral
piece. They could, however, be provided as separate members, while
still implementing the core concept of the present disclosure.
Thus, one can imagine, with reference to FIG. 1, a manually
graspable member in the form of a pull button extending from the
side faces 4, 5 of the dispenser and being attached to a separate
stack moving member. The manually graspable member would be
operable to move the stack moving member to move the stack, as
required by the present disclosure. In a less modified form from
that shown in FIG. 1, the protruding manually graspable member
could be a separate, yet attached, piece from the stack moving
member. The manually graspable member could thus be made of
different material or be of different dimension, i.e. laterally
thinner, than the stack moving member. Making them as separate
pieces could feasibly ease manufacture. They would be otherwise as
shown in the figures and described above. Similarly, a cover member
may be attached to a bottom face of the dispenser and pivotably
attached thereto to open and close the dispensing opening or be a
tear away member as described above, without being effected by the
goings on of the manually graspable member and the stack moving
member. Accordingly, the members can be integral or separate
without departing from the scope of the invention. Nonetheless, the
preferred embodiment is to have the members integral, as described
above.
[0061] In the preferred embodiment, the stack moving member takes
on a straightened form from a bent form in order to move the stack
closer to the dispensing opening, as shown by comparing FIGS. 3 and
4. It can be imagined, however, that the stack moving member
maintains a bent form in moving closer to the dispensing opening.
Thus, the planar stack moving member could be folded into an L
shaped profile when viewing the edge and be made relatively rigid.
Some sort of track or other guide, such as the side walls, could be
provided along which the stack moving member is guided in moving
from a retracted position to a position closer to the dispensing
opening by pulling on the manually graspable member. In this
modification, the stack moving member would not need to be fixed to
a rear face of the dispenser.
[0062] In another modification, the stack moving member could be
made of a resilient material so that it automatically moves back to
a retracted position relative to the dispensing opening after the
manually graspable member is released. This would require two
handed dispensing, but may offer hygienic benefits as the stack may
move with the stack moving member into a position receded from the
dispensing opening, which is where contaminants come from.
[0063] The scope of the invention is defined by the following
claims.
