Description
FIELD OF THE INVENTION
[0001] This invention relates to wipes and the like, in particular
to the packaging and dispensing of such wipes and the like.
BACKGROUND OF THE INVENTION
[0002] Packages or containers for articles such as wipes are well
known in the art. Such articles may be supplied dry or
soaked/impregnated in liquid or lotion e.g. a cleaning agent, a
solvent, a skin treating preparation, etc. Most containers for such
articles typically are in soft-pack form or in box form.
[0003] Typically, wipes have a generally rectangular planform and
in one form are supplied as interleaved or inter folded discrete
sheets stacked in a variety of different configurations, to
facilitate the so-called pop-up effect, where each wipe has a
leading portion that is first to pass through the opening, and a
trailing portion that later passes through the opening, while
dragging a leading edge of a sequential wipe into a standby
position so it extends at a convenient removal position. In other
dispensers, the wipes are simply stacked one over the other, and
the user has to reach into the package each time to grasp new
wipe.
[0004] A common arrangement is to store the individual, optionally
intercalated individual wipes in the package in a horizontal flat
configuration that facilitates removing the wipes via a narrow
dispensing opening provided at the top of the package opposed to
the base, through which the individual wipes are pulled, one at a
time, by the user. When the wipes are provided pre-soaked, the
wipes at the lower end of the package tend to become oversaturated,
and stick to one another, while the wipes at the upper end of the
package tend to be relatively drier.
[0005] Some wipe configurations and packages of general background
are disclosed in the following patents.
[0006] U.S. Pat. No. 5,310,057, U.S. Pat. No. 5,305,881 and U.S.
Pat. No. 5,577,612 disclose cartons for housing dryer sheets, which
are stacked in a "C" shape or "U" shape, and are removed via an
access flap which may include two hinges and may be reclosable.
U.S. Pat. No. 2,195,622 and U.S. Pat. No. 2,761,584 also disclose
dispensers for tissues stacked in a "C" shape.
[0007] U.S. Pat. No. 3,369,700 (GB1186787) also discloses a package
containing a stack of sheets, that is folded into an inverted U
shape and the ends of the sheets turned out to give a substantially
rectangular bundle that fits closely into a receptacle or
wrapper.
[0008] U.S. Pat. No. 3,881,632 discloses a dispensing package for
sheet materials, and comprises a top-dispensing carton, an inverted
Y-shape support member within the carton, and a bundle of
substantially uniform sheets. The bundle is folded upon itself into
a U-shape and draped over the inverted Y-shape support member. The
length of the bundle is substantially equal to the distance up and
over the inverted Y-shape support member, the middle of the bundle
is supported subjacent the top wall of the carton, and the top
sheet is folded to provide a grasping portion immediately subjacent
a dispensing opening or aperture through the top wall of the
carton.
[0009] U.S. Pat. No. 4,535,912 discloses a towelette dispenser and
vapor impervious pouch containing a roll or web of absorbent
material. A double lid is adapted to provide moisture seal between
usages of the pre-moistened towelette, while reducing dehydration
of the opened towelette pouch within the dispenser. Feed slit
adaptations in the lid provide for selective tearability of
individual towelette portions from the roll. The dispenser is
adapted to provide a low center of gravity, and the base of the
dispenser can cooperatingly engage a wall-type holder.
[0010] U.S. Pat. No. 4,506,801 discloses a construction for holding
a bag-shaped or sheet-shaped continuous plastic film. In this
holding construction, the plastic film is folded in a Z-shaped
manner such that linear cuts formed in the continuous plastic film
are accurately superposed on one another, and at least portions of
insert members are inserted into the plastic film or the insert
members are entirely inserted through the plastic film, so as to
retain the plastics film in a bundled state. If one end portion of
the film is drawn out, then a section of a predetermined length of
the film is torn off along the linear cut or cuts by means of the
insert members, and, when the section of the film is torn off, an
end portion of the succeeding, i.e. second section of the film is
automatically drawn out to a position corresponding to the position
where the end portion of the first section of the film was
initially positioned, through the action of connecting portions
other than the linear cut or cuts, so that the construction, in
which the plastic film can be easily used one section after another
in the same manner as is the pop-up take-out method of tissue
paper, can be obtained.
[0011] U.S. Pat. No. 5,918,735 discloses a package for stacked
sheets which are deformed to have their two longitudinal end
portions close to each other and to have a recess, and the two end
portions are arranged in common planes in the vertical direction.
The stacked sheets have a generally square top plan shape and to
have a small height so that they can be packaged compactly. The
sheet to be taken out is pinched upward while being held between
the two sides of the recess, and the two sides of the recess are in
parallel with the face of an outlet of the envelope. A sheet next
to the sheet to be pulled out comes into abutment with the face of
the outlet of the envelope at the two sides of the recess so that
the sheets are not taken out in a gang.
[0012] U.S. Pat. No. 6,550,633 relates to a plurality of wipes,
separable joined together. Each wipe of the plurality of wipes is
moistened with a liquid in an amount of about 25 percent to about
600 percent of a dry weight of the wipe. An adhesive joins together
at least two wipes of the plurality of wipes. The adhesive joins
the at least two wipes together with an adhesion strength per unit
adhesive length greater than 0 g/cm and less than about 200 g/cm.
Alternately or additionally, the adhesive joins the at least two
wipes together with an adhesion strength per unit adhesive area
greater than 0 g/cm.sup.2 and less than about 1000 g/cm.sup.2.

DETAILED DESCRIPTION OF EMBODIMENTS
[0039] As illustrated in FIGS. 1 and 2, a stack 10 of wipes or the
like, according to an aspect of the invention, comprises a
plurality of typically identical, discrete and individual wipes 11.
Each wipe 11 is typically rectangular in planform length L and
effective width d, having a general central portion 12, a first
pair of opposed ends 13, 14, and a second pair of opposed ends, 15,
16. Typically, each wipe 11 comes pre-folded, so that, for example,
the wipes each comprise a main panel 18 and leaf 17 folded over the
panel 18 at one end 16 thereof. Referring also to FIGS. 3a to 3c,
the effective width d of the stack 10 is similar to the width of
each panel 18, and the width d.sub.0 of the leaf 17 is smaller than
d, in some cases d.sub.0 being between about 20% and about 50% of
d, in some embodiments being between about 30% and about 40% of d.
The unfolded width of the wipe 11, designated as D (FIG. 3a), is
thus about the sum of d and d.sub.0.
[0040] By way of non-limiting example, the length L may be about
172 mm and the unfolded width D about 130 mm.
[0041] According to some embodiments of the invention, the ratio
L/D may be unity or more than 1, and/or the ratio L/d may be about
2 or greater than 2.
[0042] Optionally, the thickness and stiffness of each wipe,
together with the number of wipes 11 in the stack 10 (and thus the
thickness W of the stack 10) may be chosen such as to enable the
stack 10 to be folded over a transverse or longitudinal axes
thereof, in the form of a U, for example, such that the arms, or at
least parts thereof, of the U are at an included angle with respect
to one another of close to 0.degree., between about 5.degree. and
30.degree. for example.
[0043] Optionally, and as illustrated in FIG. 3c, adjacent wipes 11
in the stack 10 may be intercalated via leaves 17, for example,
such that a free end 15 of one wipe is accommodated in the fold
between the leaf 17 and main panel 18 of the next wipe. Thus, when
one wipe is pulled out of a package in which they may be stored,
the intercalated leaf of the adjacent wipe pulls the next wipe
partially to outside the package to facilitate pulling this wipe
out of the package in due course.
[0044] In other embodiments, the wipes may be folded at each of two
opposed ends, for example along fold lines at lateral ends 15, 16,
or indeed any other suitable fold configuration may be applied to
the wipes 11. Thus, such a fold configuration may be, for example,
U-fold, Z-fold, W-fold, and so on. In yet other embodiments, the
wipes may be unfolded.
[0045] Alternatively, the wipes 11 may be folded or unfolded, but
not intercalated, and friction between adjacent wipes may be
utilized for pulling part of the next wipe out of the package when
the previous wipe is removed therefrom.
[0046] The wipes 11 may optionally be impregnated with a suitable
solution, and the greater the degree to which adjacent wipes are
impregnated, the more they tend stick to one another at the point
of contact. For example, the wipes may optionally be impregnated
with one or more of: liquid cosmetics, such as toilet water or
milky lotion; drugs, such as an antiseptic or a medicine; cleaning
solution for cleaning skin, including alcohol, moisturizing agent,
surfactant and so on; or solution for wiping stains or for cleaning
kitchens, bathrooms, furniture, and so on, including alcohol,
agent, surfactant and so on.
[0047] According to some aspects of the invention, and referring to
FIGS. 4a and 4b, the stack 11 may be packaged in a flexible pack
50, which may be similar, in some respects to other such packs know
in the art. For example, the pack 50 may be made from a flexible
sheet suitably folded and bonded to provide an internal space or
chamber 54 that may be partially filled with wipes to be dispensed.
The flexible sheet is typically bonded along a longitudinal join
(not shown) and at the longitudinal ends via seams 52.
[0048] The flexible sheet constituting the pack 50 may comprise,
for example, synthetic resins such as polyethylene, polypropylene,
polyamide, polyester, and polyvinyl chloride in the form of a film,
and the film may be a single layer or a laminated layer. The film
may be a laminated layer of the above-mentioned film and an
aluminum foil or paper, and the pack 50 is generally
deformable.
[0049] The sheet constituting a pack 50 may be gas impervious or
liquid impervious depending on the kind of the liquid impregnated
in wipes, i.e., fibrous materials impregnated with liquid cosmetics
or a medicine, contained in the pack 50. For example, it may be
preferred to use a sheet which is impervious to both gas and
liquid, when perfumes which are very volatile are contained in the
liquid.
[0050] According to one aspect of the invention, the volume of the
chamber 54 formed therein between the two seams is substantially
larger than the volume occupied by the stack 10, such that the pack
10 may be loosely accommodated therein. The longitudinal length S
of the pack 50 may be considered to be the sum of the length L of
the pack, the seam lengths n, which can be assumed to be generally
identical, and the diagonal lengths m of the end portions 51 of the
pack 50 between the longitudinal ends of the stack 10 and the
corresponding seam 54.
[0051] Thus, S=L+(2*n)+(2*m)
[0052] The length n of each of the end portions 51 are generally
longer than half the thickness W of the stack 10, and thus, for
example using trigonometrical or geometrical relationships for an
imaginary right angle triangle formed between one end of the stack
10 and the seam 54 (FIG. 4a), it may be seen that m=(W/2)+Q
[0053] Thus, S=L+W+(2*n)+(2*Q)
[0054] The value of Q may be chosen such as to allow the stack 10
to be longitudinally displaced within the chamber 54. In
particular, the value of Q may also be chosen such as to allow
deformation of the pack 50 when this is folded, for example as
illustrated in FIG. 4b, providing for creasing in the concave part
of the folded pack, while still allowing relative movement between
the stack 10 and the pack 50. The relatively long pack length S
relative to the stack length L may reduce the otherwise large shear
forces that could otherwise arise when pulling out at least the
first few wipes 10 from the pack 50 in the folded configuration
illustrated in FIG. 4b.
[0055] By way of example, the longitudinal dimension S may be
longer than the length L of the pack, for example by between about
10% and about 60%, between about 15% and about 50%, more particular
between about 20% and about 40% of the length L of the pack 11,
thereby providing a significant longitudinal spacing, for example
equal to or greater than the thickness dimension W, may be formed
between each longitudinal end of the stack 11 and the corresponding
seam 52.
[0056] Similarly, the width of the pack 50 may optionally be
substantially larger than the effective width d of the stack 10,
allowing substantial relative sideways movement between the stack
10 and the chamber 54.
[0057] Furthermore, the chamber 54 may be at least partially
evacuated, and thus at about ambient or sub-ambient pressure.
[0058] According to such embodiments, the pack 50, comprising a
stack 11, may be folded over about a transverse axis, for example a
mid-point transverse axis 56, with little resistance. An optionally
resealable opening 58 may be provided at the mid point of the pack
50, or alternatively at a position displaced from the centre of the
pack and proximate to one of the seams 52. In some applications, it
may be better for the stack 10 to be thin (dimension W), and/or the
wipes not to be stiff, and/or for the wipes to be relatively long
(and/or wide) with respect to the thickness of the stack.
[0059] According to some aspects of the invention, and referring to
FIG. 4b, the pack 50 is foldable to a folded configuration, for
example a U-configuration, about a transverse axis or about a
longitudinal axis, where the arms (or parts thereof) of the U form
an angle .theta. therebetween of 0.degree. or greater, in some
embodiments between about 5.degree. and about 30.degree..
[0060] According to some aspects of the invention, the stack 11,
optionally packaged in a pack 50, may be accommodated within a
suitable housing having a base adapted for standing the housing on
a generally horizontal surface, such that each wipe 11 has the
central portion 12 thereof vertically displaced upwards with
respect to at least one extreme portion thereof, in some
embodiments being extreme non-folded portion thereof, typically at
least one of the ends 13, 14 or, 15 thereof. In this respect, the
aforesaid "extreme portion" refers to any extremity of the wipe 11,
for example also including any one of the corners 19, and thus may
be a function of how the wipes 11 are arranged in the housing in
relation to the base thereof. Thus, the wipes may have any shape
other than rectangular, for example polygonal, oval, circular,
irregular, and so on: according to aspects of the invention, the
wipes are accommodated in the housing such that typically the
central portion of each wipe is vertically displaced from at least
one extremity of the wipe.
[0061] Thus, according to one embodiment of the invention, the
stack 10 is arranged in an appropriate housing, optionally packaged
together in a pack 50, in a generally vertical orientation, herein
referred to as the "vertical stack configuration", such that for
each wipe 11, one non-folded end 14 thereof is at a generally
bottom or relatively lower position B, while the opposed end 13 is
at a generally top or relatively upper position T, for example as
illustrated in FIG. 1.
[0062] According to another embodiment of the invention, and
referring to FIG. 4b, for example, the stack 10 may be arranged in
an appropriate housing in a generally inverted V or inverted U
manner (when viewed from one side), herein referred to collectively
as the "inverted V configuration", such that for each wipe 11
thereof, the two opposed non-folded ends 13, 14 thereof are at a
generally bottom or relatively lower position, while the central
portion 12 is at a generally top or relatively upper position.
[0063] In another variation of the embodiment of FIG. 4b, the stack
10, in inverted V configuration, has one arm or the V longer than
the other, so that rather than the central section, an intermediate
portion 23 is at the uppermost position, and while ends 13, 14 are
vertically displaced downwards with respect thereto, one such end
is lower than the other opposed end.
[0064] According to some aspects of the invention, the stack of
wipes may adopt any other suitable configuration, so that at least
one portion of the wipes distanced from an extremity of the wipes
is vertically displaced with respect to the extremity of the wipe.
For example, for long wipes, having a relatively high length to
width ratio, L/d, the pack 10 may adopt an "M", "W", "N" or "S" (or
"Z") configuration, in which the central portion 12 and in
particular intermediate portion 23 between the central portion 12
and one non-folded end (for example 13) are upwardly vertically
displaced with respect to end 13.
[0065] According to some aspects of the present invention, a
dispensing container, generally referred to herein also as a
"container", is provided for storing and dispensing wipes or the
like, in some embodiments thereof the wipes being stacked therein
in a manner according to the invention, for example as an
unpackaged stack 10, or packed in a pack 50.
[0066] Thus, according to a first embodiment of a container
according to one aspect of the invention, and referring to FIGS.
5a, 5b, 5c and 6, a container 100 is particularly adapted for
accommodating a stack 10 of wipes 11, optionally packed in a pack
50, in the inverted V configuration. The container 100 is of
generally rigid or semi-rigid construction, and comprises a housing
110 of generally prismatic or pyramidal shape, having a dispensing
opening 162 at a top portion 112 thereof, and an open bottom end
114. The housing 110 typically comprises a pair of opposed
generally trapezium-shaped side walls 115, 116, which are typically
planar and are laterally joined at optionally rounded side edges
117 to generally rectangular or trapezium-shaped opposed side walls
118, 119. The housing is reversibly mountable to a base 130 by
means of a suitable arrangement, for example a snap-fit
arrangement. Optionally, a lever 131 may be provided on the base
130 for facilitating separating the base 130 from the housing
110.
[0067] Alternatively, the base 130 may be hinged to the housing 110
along an edge comprising a film hinge or any other suitable hinge
arrangement, for example, and further comprise a suitable lock
arrangement (not shown) to reversibly lock the base in the closed
position with respect to the housing 110. The base is configured
for resting on a generally horizontal surface, and may comprise a
planar bottom face, and/or legs (not shown), and/or a
downwardly-projecting skirt (not shown) circumscribing the
periphery of the base, for example.
[0068] In variations of this embodiment, the base 130 may
optionally comprise an upwardly projecting web (not shown) which
may be in the form of an inverted V having a rounded top, for
example, and transversely extend between walls 115, 116 to define a
generally inverted V or inverted U shaped chamber in the housing,
adapted for accommodating an inverted V-configuration stack 10,
such that the stack is supported by the web in the container 100.
In the embodiment illustrated in FIGS. 5a to 6, however, the stack
10, particularly when accommodated in a pack 50, is accommodated
within the housing in an inverted V-configuration, without any such
web. The inverted V configuration for the pack 50 may be aided by
means of sloping walls side walls 118, 119.
[0069] The housing typically further comprises a reversibly
closable lid 160, which may be removably mounted to the top portion
112, or hinged with respect thereto, for example, for reversibly
closing over the dispensing opening 162. The lid may act as a dust
cover on the one hand to prevent contamination of the wipes 11, and
on the other hand may retard or prevent evaporation of the wetting
agents in the wipes, particularly the leading edge portion of the
wipe that may be protruding from the dispensing opening 162. The
dispensing opening 162 may optionally comprise a restricted opening
(not shown) for holding therein a leading edge of a wipe, and may
thus take any suitable form, for example an "X", slit, and so
on.
[0070] Optionally, the lid 160 may be adapted to be spring loaded,
either when closed, or when initiating an opening procedure, and as
such enables the dispensing opening to be opened with a single hand
action, for example by means of depressible button 161, that may be
covered by cover 163. There are many examples of such lids in the
art, and will not be described further herein.
[0071] Alternatively, and as illustrated in FIGS. 5d and 5e, the
lid 160 may be reversibly lockable by means of a latch arrangement,
wherein, for example, the lid 160 comprises a projecting lip 164,
which is reversibly engaged with respect to a complementary
projection or recess (not illustrated) provided in the housing 110.
Optionally, a deformable button 165, integrally formed with the
projection/recess, may be deformed by pressing with a finger, such
as to release engagement of the lip 164, enabling the lid 160 to
open.
[0072] The dispensing opening 162 is arranged to be substantially
in registry with the central portion 12 of the wipes 11 in the
stack 10. Thus, each wipe 11 is pulled out of the dispensing
opening via the corresponding central portion 12 thereof. When
applied for use with wetted wipes, by virtue of the inverted V
configuration, the central portion 12 tends to be less saturated
with wetting agent than the ends 13, 14, and thus the central
portion 12 of the leading wipe is substantially more detached from
the central portion of the next wipe, which facilitates total
separation of the leading wipe from the stack 10. In embodiments
where the stack 10 is packed in pack 50, the centrally-located pack
opening 58 is in registry with the opening 50, facilitating
dispensing of the wipes 11 from the pack 50.
[0073] Alternatively, in a variation of this embodiment, the
dispensing opening may be formed in one or the other, or indeed on
both of the side walls 118, 119, i.e., with the opening formed for
example on wall 118 inclined to the base, so that each wipe 11 of a
stack 10 is pulled by the intermediate portion 23 thereof. When
applied for use with wetted wipes, these portions are also less
saturated than the ends 13, 14, thus relatively trouble free
dispensing of the wipe is possible, wherein adjacent wipes fully
sticking to one another is avoided. In embodiments where the stack
11 is packed in a pack 50, the opening in such a pack is offset
from the center of the pack to a position that would be in registry
with the dispensing opening of the housing when the pack is
accommodated therein.
[0074] According to some aspects of the invention, a dispensing
system, optionally in the form of a dispensing kit, is provided,
comprising said container 100 and one or more said packs 50,
wherein the container 100 is loaded with one such pack enabling
wipes to be dispensed via the container opening 162; when the wipes
thereof are fully dispensed, the empty pack 50 may be removed and
replaced with a new pack 50, folded about a transverse axis 56 into
an inverted V configuration.
[0075] According to a second embodiment of the invention, and
referring to FIGS. 7, 8 and 9, a rigid or semi-rigid container 200
is provided, particularly suitable for dispensing wipes 11 from a
stack 10 in the vertical stack configuration. In this embodiment, a
substantially frusto-conical housing 210 is provided having a base
230 that is adapted for enabling the container to stand on a
substantially horizontal surface, and an upper opening 214. The
stack 10 may be accommodated in the housing or alternatively, a
pack 50 of wipes may be accommodated in the housing, in either case
folded about a longitudinal axis 56 thereof. Referring to FIG. 9 in
particular, the wipes are also partially folded in a circular C
configuration with respect to a longitudinal axis, so that
non-folded edges 13, 14, are in the form of a C, i.e., when the
stack is viewed from above, such as to be snuggly accommodated in
the cylindrical chamber 250 provided in the housing 210. An
inwardly projecting radial web 150 may optionally be provided,
typically extending along part or the full the height of the
housing 210, to assist in holding the stack 10 in place within the
chamber 250. The housing further comprises a dispensing opening
262, which is illustrated in the form of an oval aperture (but may
optionally also be in the form of a slot or in any other suitable
form) provided at an upper portion 212 of the housing: The opening
262 may be formed so as to be in registry with the mid-point 25 of
the upper end 13, but may instead be closer to one or the other of
the upper corners of the wipes 11 that may be accommodated in the
housing. Alternatively, the opening 262 may be formed at the center
portion, vertically, of the housing 210, or at an intermediate
portion between this center portion and the open upper end 214 of
the housing 210, such that the opening is in registry with the
central portion 12 or intermediate portion 23, respectively, of the
wipes 11 in the stack 10. The housing 210 comprises an upward
facing annular shoulder 211, intermediate between the base 230 and
the upper opening 214, defining the upper portion 212. A lower
portion 215 may be defined between the shoulder 211 and the base
230.
[0076] The container 200 further comprises a generally
frusto-conical cover 260, having a cap 261 for closing the
relatively larger upper end of the cover 261, for example via a
snap-fit connection or a suitable hinge arrangement, detachably
mounted to an upper edge of frusto conical wall 267, and a
relatively smaller open bottom end 263. The cover 260 is adapted
for being optionally reversibly mounted to the upper portion 212 of
the housing 210, for rotation with respect thereto; in particular,
the bottom edge 268 of the cover 260 rests on and may rotate with
respect to, the shoulder 211.
[0077] Additionally, the cover 260 comprises an opening 265 at a
position such as to enable the dispensing opening 262 to be in
registry therewith as the cover is rotated with respect to the
housing to a dispensing position about longitudinal axis 269. Thus,
in the dispensing position, a leading portion of the leading wipe
is protruding via both openings 262 and 265, which are in registry,
enabling the leading wipe to be extracted, which action may
optionally serve to pull out the leading portion of the next wipe
into a standby position. As the cover 260 is rotated such that the
opening 265 is angularly displaced away from opening 262, the
latter is closed off by means of the wall 267 of the cover 260.
Moreover, if prior to such a rotation the leading edge of a wipe
happens to be protruding from the two openings 262, 265, the inner
opening 262 tends to hold the leading edge in place with respect
thereto, while circumferentially slipping away from the outer
opening 265 as the cover 260 is rotated with respect to the housing
210. In this manner, the leading edge is accommodated in an annular
space between the inner cylindrical face of the cover 260 and the
outer cylindrical face of the upper portion 212 of the housing 210,
and not directly exposed to the external environment. By reversing
the rotation of the cover 260, the leading edge of the wipe may be
automatically threaded therethrough as the outer opening 265 is
again brought into registry with the inner opening 262.
[0078] The cover 260 may be adapted for rotating in one or both
senses about axis 269 of the container, and may be freely rotatable
to any angle, even exceeding a full 360.degree. revolution, or
alternatively may be restricted to turn within a limited angular
displacement, typically by means of suitable stops (not shown) or
the like.
[0079] Optionally, the cover 260 may comprise tabs or ears (not
shown), or finger grasping indentations formed on the cylindrical
wall 267 and/or the cap 261, for facilitating rotation of the cover
260 by the user.
[0080] When the cover 260 is reversibly mounted to the housing 210,
the cover 260 or the cap 261 may be removed for the sake of
refilling the container with a new stack 10 when this is necessary.
If it is desired to remove the whole cover 260, this may be
accomplished by first detaching the cap 261 from the wall 267, and
then pushing the wall in a direction towards the base 230, with
respect to the housing 210. Either way, the opening 214 is exposed,
enabling a new stack to be placed into the housing 210.
[0081] In a variation of this embodiment, the container 210 may
comprise a reversibly closed or integrally closed top having the
dispensing opening thereat, in the form of a radial slot, for
example, and similarly, the cover has a corresponding dispensing
opening on the closed upper end 261 thereof. Thus, optionally, the
lower end of the housing 210 may be adapted for enabling the
container to be refilled with a new stack 10, and for example, the
base 230 may be reversibly mounted to the lower portion 215 of the
housing 210, for example in the form of a lower lid, to provide the
required access to the chamber 250.
[0082] When the second embodiment is applied for use with wetted
wipes, the upper portion of the wipes 11 are typically less
impregnated than the central portion 12 or lower portion including
lower end 14. Thus, by pulling the leading wipe by the upper end 13
or upper intermediate portion 23, or even the central portion 12,
the less stickiness between these portions of the leading wipe and
the next wipe, and possibly the upwardly decreasing differential
saturation along the vertical length of the wipe 11, helps to free
the leading wipe from the stack 10 such that it does not tend to
completely pull out one or more additional wipes in the same
movement.
[0083] Optionally, radial stops 218 may be provided on the housing
210 to prevent or limit rolling of the container 200 when the axis
269 is generally horizontal or close thereto.
[0084] While the container has been described as having lower base
230 and an upper cover 260, the container may be used in an
inverted configuration, in which the cap 261 acts as a base, and
the base 231 is now uppermost.
[0085] In variations of this embodiment, the housing 210 and cover
260 may be substantially cylindrical and/or having a circular,
polygonal, or oval cross-section, similar to the embodiment
described with reference to FIGS. 7 to 9, mutatis mutandis. In
embodiments where the cross-section is non-circular, the housing
210 (in particular the upper portion 212 thereof) and/or the cover
may be made from a material and/or of thickness such as to enable
one or both components to partially deform so as to permit the
relative rotation therebetween, Optionally, the lower portion 215
may be frusto-conical and/or the upper portion 210 and cover 260
may be generally tubular, for example.
[0086] According to a third embodiment of the invention, and
referring to FIGS. 10 to 12, a rigid or semi-rigid container 300 is
provided, particularly suitable for dispensing wipes 11 from a
stack 10 in the vertical stack configuration, optionally
accommodated in a pack 50 provided in the container 300. In this
embodiment, a generally oval lower housing 310 is provided having
upwardly projecting peripheral wall 315 from a base 312 that is
adapted for enabling the container to stand on a substantially
horizontal surface. In particular, the cross-section of the housing
may be crescent-shaped, having substantially rounded ends, the
cross-section thus being e.g., bean-shaped or kidney-shaped. Thus,
the housing may comprise a convex and concave opposed front and
rear walls, 315a, 315b, respectively, connected to side walls 315c,
315d, which together define peripheral wall 315. This arrangement
may provide improved stability for the container 30 when resting
this on a horizontal surface, particularly when the container is
adapted for accommodating a relatively thin stack of wipes, and
thus the front and rear walls are spaced by a relatively narrow
spacing.
[0087] The housing 310 has a upper open end via which the container
300 may be refilled with a new stack 10 or pack 50 when necessary,
and a generally horizontal outwardly laterally extending flange or
lip 311 is provide at the upper open end (see FIG. 12a). A
generally oval upper cover 360 optionally having a similar
cross-section to the housing 310, is provided having downwardly
projecting side wall 365 from a top wall 362. Also referring to
FIG. 12a, the lower portion of the side wall 365 comprises an
outwardly laterally displaced skirt or portion 366, having a
generally horizontal inwardly laterally extending flange or lip 375
provided at the lower edge of the cover 360. The cover 360 may be
reversibly snap-fitted onto the housing 310 by deforming the lip
375 until the upper part thereof engages with the lower part of the
lip 311. In the illustrated embodiment, the longitudinal length
L.sub.1 of the housing 310 may be between about 10% and about 90%
of the overall longitudinal length L.sub.0 of the container 300. In
other embodiments, the longitudinal length L.sub.1 of the housing
310 may be between about 60% and about 80% of the overall
longitudinal length L.sub.0 of the container 300.
[0088] Referring in particular to FIG. 12, the cover 360 is
provided with a dispensing opening 361, generally positioned to be
opposite the mid-point 25 of the upper end 13 of a stack 10 that
may be accommodated in the container 300, but may instead be closer
to one or the other of the upper corners of the wipes 11. In
particular, the opening 361 may be formed in a recessed portion 340
of the wall 365. Further, the opening 361 may be formed at an
intermediate portion of the cover 360, such that the opening 361 is
in registry with the intermediate portion 23, of the wipes 11 in
the stack 10. An L-shaped flap 370 is hingedly mounted to the lower
portion of the cover 360, for example in proximity to the portion
366, via an integral film hinge or other hinge for example, and is
dimensioned so as to close with respect to recessed portion 340 in
a general flush manner with respect to wall 365, and preferably
also top portion 362. Optionally, the housing 310 and cover 360 may
have any other suitable cross-sectional profile, for example,
regular oval or elliptical, when viewed from above.
[0089] Optionally, and referring to FIG. 12a, the housing may
comprise an arrangement for protecting the lip 375, and for
preventing unwanted separation of cover 360 with respect to the
housing 310, as may otherwise occur, for example, if the lip 375
where to receive a sharp knock. The protecting arrangement may
comprise, for example, a radial flange 390, projecting outwardly
from the housing, and spaced fro the lip 375 when the cover is
connected to the housing. Alternatively the arrangement may
comprise a plurality of tabs or the like. Other protection
arrangements are also possible.
[0090] Alternatively, and as illustrated in FIGS. 13 and 14, in
another embodiment of the invention, a container 300' similar to
that described in respect of the embodiment of FIGS. 10 to 12,
mutatis mutandis, may comprise an upper dispensing opening 361', at
the upper longitudinal end of the container 300', closable via lid
370', and thus the housing 310' may be relatively longer, and the
cover 360' relatively shorter, than the corresponding components of
container 300, mutatis mutandis. In this embodiment, wipes 11 of a
stack 10 may be removed from the container 300' via the unfolded
upper end 13 thereof, for example.
[0091] In another embodiment of the container according to the
invention, and referring to FIGS. 15 and 16, the container 400 is
similar to the container of the embodiment of FIGS. 13 and 14, but
with the following differences, mutatis mutandis. In this
embodiment, cover 490 comprises an upper hinged lid 492, rather
than an L-shaped lid, and the dispensing opening 462 is at the top
rather than the side wall, of the container.
[0092] The above container embodiments may be made from rigid or
semi-rigid materials, including plastic materials. Accordingly, the
housing and base and other components of the container may in each
embodiment be manufactured using suitable forming molds. Such molds
may include molds adapted for any suitable plastic forming process,
including, for example but limited to, any one of, as appropriate:
injection molding, blowmolding, vacuum forming, pressure forming,
thermo-forming, rotomolding, reaction injection molding, reinforced
reaction injection molding, and so on. Optionally, such components
may be formed as multi-component articles of manufacture, for
example having parts of a component of different stiffness and/or
material being integrally formed. Alternatively, such components
may be formed from several parts which may be assembled or joined
together.
[0093] For each of the embodiments disclosed herein, optionally, a
removable adhesive strip may be provided over the respective wipe
opening to cover the same until first use thereof. The opening is
preferably sized for dispensing one wipe at a time while separating
a standby or duty wipe from a successive wipe. The arrangement with
such wipes is preferably such that upon pulling a leading edge of a
standby wipe (by using the term "standby wipe" is referred to a
first wipe in a pack of wipes which is to be removed from the
container), the standby wipe is withdrawn through the opening
whilst it detaches from the sequential wipe, which becomes in turn
a duty wipe with its leading edge now projecting from the
opening.
