Abstract
A storing and dispensing system for pre-moistened tissues or granular products comprises a container (3) which is closable in a fluid tight manner and a pouch (5) having a sealed dispensing aperture (10) which after opening can be placed in the container (3). Opening the pouch (5) at a preformed dispensing aperture (10) and placing the tissues or granular products together with the pouch (5) in the container (3) instead of first removing the contents from the pouch (5), results in a better protection of the tissues or granules upon accidental falling and prevents contamination of the container (3) by for instance mould growth due to contact with wet tissues. The pouch (5) is preferably provided with means to affix it to the inside of the container (3) the container (3) having at its bottom an antislip support (39,41). The pouch (5) can contain products of a granular nature. The label (7) closing the pouch dispensing aperture (10) can be applied to a receiving surface of the container (3) and can be re-applied to the pouch (5).
Description
W~ 93/17933 P~/US93/01896 STORING AND DISPENSING SYSTEM FOR PR~OOUCTS PACKED
IN A SEALED POUCH
Field of the invention , The invention relates to a storing and dispensing system for a product paclced in a sealed poueh, the system cornprising:
- a container of relatively rigid matcrial having a dispensing openiIlg which is covered by a iid, the container bemg in its closed position sufficien~ly air-tight to prevent free excha~ge of air between the container's conteIlts and the ambient, and a sealed pouch in which a produc~ is contained, the pouch comprising a topface having opening means for m~n~l~lly opening the pouch, the pouch being a~ter opening thereof storable inside the cont~iner, the opening means comprising a pre-farmed dispensmg aperture which is openably sealed by a cover member which is removable from the~ dispensing ape~ture.
Backyround of the invention Such a system, wherein the pouch comprises pre-mois~ened tissues, is rnarketed by Scott Paper Co., Philadelphia, PA 19113, US~, under the tradç name 33aby Fresh.
In this system, a refill pouch made of l~min~te.~ polyethylene film contains a folded stack of wet baby wipes. On a ~op~ace of the pouch. the film is provided with a line of weakening, the top~ace ~eing covered by a glued-on eab that firmly adheres to ~he topface. To open the pouch, the ~ab is pulled so that the film of the pollch is ripped and the contents are exposed. To prevent the moist tissues ~rom drying out, they can be taken from the pouch and placed inside a box-shaped piastic container. It is W0 93/17933 Pcr/US93/01896 ' 2l319~72 .-'''' ~:,, also possible to place the opened pouch inside the eontainer as is shown in instructions on the pouch.
The above described refill system has as an advantage that by multiple use of the container, the waste coming from used-up product is reduced.
Upoi1 opening of the pouch however, the top~ace and the side face of the pouch are torn in a relatively irregular manner, so that the sides of the stack of tissues are e~posed. Upon dispensing of the stack's topmost -tissue from the container~ the underlying tissues can accidentally be touched so that the hygienic conditions of those tissues deteriorates.
Because the moist ~issues san through the rip in the pouch contact the inside of the container, the container can in eourse of time be con~min~ted by the mois~ure of the tissues.
A s~oring and dispensing system containing a pouch which has a F~e- -~
formed dispensing apernlre is known from the European patent application EP-A-O 370 192.
:
In this patent application a paperboard box is described for storage and dispensin~g of a stack of moist ~iss~es. The paperboard box has a dispensing opening which is covered by a paperboard lid that can be opened along a pre-perforated line. The paperboard box is at its inside provided with a fluid-impervious layer of polyethylene, whieh is opened at the same time as the box is opened. In another embodiment~ the paper~oard box is provided with a liquid impervious, sealed, inner poueh in which the napkins are contained. The pouch is in the area of the dispensing opening of the ~ox affixed to the inside of the box. The inner pouch can be opened by tearing loose a tab which remains at one end fixed,to the pouch and which can be folded baek over the p~uch's aperture ~or reclosure.
:..
The storing nd dispensing system of this kind is not fit for multiple use, no refill being possible after the con~ents of ~he box have been used. Also is the recloseability of the known system limited sance the tab of the pouch, that functions as a sealing lid a~er first time opening, rests on the peripheral edge of the dispensing aperture in a non-sealing manner. ~ ~~
WO 93J17933 21 31 9 f3 7 PCr/US93/01896 , In the French patent FR-A-~ 376 802, a pouch containing moist tissues is disclosed, in which an oval shaped line of weakening is provided in the topface of the pouch. The topface of the pouch is covered by an adhesive label which upon removal tears the topface along the line weakening. the pouch material which is stuck to thc bottom of th~ adhesiYe label is removed from the pouch together with the label and a well-defined dispensing apern~re is formed after opening. The pouch can be stored in a container.
Ob;ects of the invention It is an object of the invention to pro~ide for a s~orage and dispensing system for products packed in a sealed pouch, wherein the arnoun~ of waste from used paclcaging material is reduced, which allows easy handling and in which hygienic conditions prevail.
It is another object of the invention to provide for a storage and dispensing system that allows for easy dispensing of the products from the pouch after placement inside the container and in which con~min~tion of the con~ainer by the contents ~rom the pouch, and vice versa, is prevented.
It is a filrther ob3ect of the invention to provide a storage and dispensing system in which the pouch after opening a~ter first time use, can be easily transported without the container.
It is again another obje~t of the invention to provide a storing and dispensing system which can be stably positioned and is suitable for being usedi single-handedly.
It is a still filrther object of the invention to provide a storing and ~ -dispensing system which is sui~able ~or cont~ in~ vacuum packed granular products.
Summary of the invention wo 93/ ~ 7933 ~ 1 3 1 3 0 7 Pcr/lJss3/01 a96 -~ -A storing and dispensing system according to the invention is characterized in that the cover member can be comple~ely detached from :
the pouch without substantially damaging the cover member or the pouch, the cover member comprising an adhesive adapted for adhesively ; .
refastening the cover member over the dispensing aperture subsequent to detachment of the cover member. -Because of the pre-formed dispensing apernlre in the ~opface of the pouch, ripping of the pouch upon removal of the t~b fr~m the top~ace~ is prevented. The clearly defined dispensing aperture, which can be formed by a cut in the pouch or by a line of weakening, does after opening not allow access to the tissues located underneath the topmost tissue. Since the pouch is, upon opening, not ripped in an arbitrary manner, the conten~s do not spill from the pouch upon placing of it in the container or upon dispensing product from the pouch when i~ is placed inside the container. This is especially important when the pouch contains a granular product such as ground coffee or detergent powder, which, in c~se the pouch is ripped upon opening, is easily spilled there~rom.
The c~ver member can after opening of the pouch ~e removed from the pouch's surface and can be ~t~cherl to a receiving sur~ace of the container. In thi~ way the cover membér's adhesive is protected from dust or other cont~n1in~tion. When the pouch is to be reclosed for transport, the cover mem~er can be detached from the container's receiving surface and re-applied to the pouch. Transporting the pouch without the conta~ner is often convenient due to the better conformability ~:-of ~he pouch compared to the relatively rigid container. Also, if some of -~he contents ~rom the pouch have been used, the pouch can be compressed to a smaller volume than the container.
After removal of the cover member from the pouch, it is advantageous to stick the cover member to the inside of the cont~iner's lid, so that each time upon opening of the container, the text or symbols of the label, which can comprise instructio~is ~or use, can be viewed by the user. It is important that the surface of the pouch to which the cover member is attached is of sufficient smoothness for the glue of the eover member to be easily released therefrom. The same applies for the container's 3 PCI/US93/0189~
5 ~1319 0~ ~
sur~ace to which the cover member is attached after removal from the pouch.
~.
A glue suitable ~or use on the cover member is produced by MACtac Europe SA, Boulevard Kennedy 7060 Soignies, Belgium~ under type number MR980. Especially when the pouch contains moistened tissues, such as we~ baby wipes~ it is desirable that the pouch can be transported without the con~ainer, which due to its rigidaty often cannot very easily be han~led during transport. By allowing the cover member to be removed ~rom the container and re-fastened across the dispensing aperture~ the s~oring and dispensing system according to the invention combines the advantages of a reclosable and easi}y transportable travel pack with the easy dispensing facility and good sealing properties of a cont~iner and its refill pack.
Another embodiment of a storing and dispcnsing system according to the invention is characterized in that the cont iner is provided with an anti-slip support for exer~ing a ~orce on the container for preventing movemen~ of the container in a direction perpendicular and/or parallel to a supporting surface on which the cont~iner is placeable.
The anti-slip support can comprise a number of suction rlaps Velcro tapes or glue tapes engaging the supporting surface. It can also comprise a hole in the bottom of ~he container through which a part of the glue tape tha~ is attached to the pouch, for restriction of movement of the youch with respect to the container, can project and can contact the supporting surface. When the container is unable to move with respect to its supporeing surface, both in a direction parallel and perpendicular to ~he supporting s~rface, the container ~an be opened and a ~issue can be dispensed from the pouch by a user while only using one hand. Also the rislc of tipping over the container when most of the tissues have been :~
used, the container having at that time a rcduced weight and reduced stability, is reduced when fixing the container to the supporting surf2ce.
A further embodiment of a storing and dispensing system accQrding to the invention is characterized in that the product cont~ined in the pouch is of a granular nanIre.
wo 93/17933 Pcr/uss3/0l8s6 21319~ 6 It is known from EP-A-O 467 481 to pack ~ranular dctergents in a compact form~ by packing the detergent in a pouch under vacuum, or by ~: -packing detergents in a heat shrinkable foil which is shrunk to compress the detergent. Another way of compact packaging of products, comprises packing the products in a pouch under compression. In a similar m~nner it is known to pack ground coffee in a pouch under vacuum.
It was found that for granular products, ra~her than pouring these products, after opening of the pouch, into the container, it as preferred to plaLce the pouch containing the granular product inside the container. This will reduce the chance of spilling of product. Also, the sealing properties of the pouch will be partly maintained so that better protection of the product against drying out or loss of arorna is provided compared to when the pouch is absent. Providing a pre-formed dispensing aperture in the pouch containing granular products prevents the pouch from ripping in an arbitrary manner upon opening and reduces the chance of spilling of the granular products from the pouch into ~he container.
.
For granular products that are paeked under vacuum7 it is essential that an airtight seal is formed by the cover member overlying the daspensing :
apernlre. For products that are packed under compression, the cover member must be su~lciently strong to adhere to the pouch without the expansion forces of the packed produet det~ching the cover member.
,..~., Again another esnbodiment of a storing and dispensing system according ~o the inYention is characterized in that the pre-formed dispensing aperture comprises a peripheral edge, the dispensing aperture exclusively extending in the plane of orle face of the pouch so that upon placing of the pouch in the container, the dispensing aperture is parallel with the dispensing opening, the peripheral edge of the dispensing apernlre at most partly coinciding wi~h a circumferential edge of the topface.
The dispensing aperture of the pouch is confined to lie in only one face of the pouch and is of smaller size than this face. Wherl the pouch contains pre-moistened tissues, ~he pouch material of the topface surrounding the dispensing apernlre covers the edges of the moist tissues that lie W~ 93/~7933 PCI'/US93/01896 underneath this pouch material and restricts movement thereof. Upon pulling the topmost tissue from the st~ck through the dispensing aperture, the restriction of ~he tissues' edges by the peripheral edge, cause t~e tissues to unfold from their flattened state. The edges of the topface surrounding the dispensing aperture prevent the sid~faces of the pouch from collapsing and prevent, in case the pouch contains a granular pro~uct, spilling of the granular contents into the container. The dispensing aperture is preferably elliptical, but can be round or rectangular.
Qgain another embodiment of a storing and dispensing system according to ~he inventiorl is characterized in that the dispensing aperture is formed by a hole extending through the topface of the pouch or by an endless line of weakening, the dispensing aperture being covered by a tab of larger size than the dispensing aperture, the tab being connected to the pouch along the peripheral edge of the dispensing aperture.
The dispensing ape~ture of the pouch is before first time use covered by a sealing tab that can be glued over the dispensing aperture and tha~ can be easi~y removed therefrom. Prefierably a peeling force of the tab does not exceed between 0.8 and 1.2 N/cm. Use~ul materials for the tab comprise Polyvinyl chloride, polyethylene, polyethylene tereph~h~l~te, polypropyl~ne and polystyrene, either as single layers or l~rnin~te-~ in cornbination. :
Again another embodiment of storing and dispensing system according to the invention is ct~aract~rized in that the pouch comprises a l~min~te of at least two layers, an outer layer comprising the dispensing aperture, the inner layer being continuous and covering the dispensing apernlre, the opening me~n.~ comprising a tab that within the boundaries of the dispensing aperture is connected to the inne~ layer which is sufficiently ~ .
thin to be ~orn upon removal of the tab from the dispensing apernlre.
An airtight pouch that can be easily opened is made by ~orming the po~lch's dispensing aperture in a first layer ~that can for instance consist of aluminium) by pre-cutting a hole therein or by providing a pre-formed line of weakening, and by subsequently l~min~ing a second layer (for wo 93/17933 2 1 3 1 ~ 0 7 Pcr/uss3/olgg6 " ~
instance polyethylene) with the first layer. In case a hole is pre-cut in the first 1ayer, the second layer, which is before opening of the pouch a continuous layer, prevents contact of the contents of the pouch and~the tab that is glued over the dispensing aperture for opening. Pouches of this kind are especially useful for containing aseptic products. A method for producing a lamin~e of two layers, one of which having a pre-cut aperture or a pre-formed line of weakening, is disclosed in the European patent application EP-A- 191525, which is incorpora~ed herein by reference.
Another embodiment of a storing and dispensing system accQrding to the invention is characterized in that the pouch comprises a l~min~te of at east two layers, an inner layer comprising the dispensing apern~re which is formed by a hole extending thr~ugh the inner layer or by an endless Iine of weakening, the dispensing aperture being covered by a tab of -~
larger si~e, the tab being an integral part of the outer layer of the pouch ~:~
and being formed by a cu~ or a line of weakening in the outer layer.
The inncr layerpreven~s con~ct of mois~re from the pouch's contents withthe cut or the line of weakening in the outer layer of the pouch.
Especial~yifthe pouchis made ofa paper l~min~te, theinnerlayer prevents migration of liquid into the paper. Also, sincethe outerlayer of the pouch functions as the label, a single printing step su~fices for providingthe ou~ide ofthe pouch withinstructions for opening and/or decorative prin~ing. No extra prin~ing of a separate label is necessary.
Again another embodiment of a storing and dispensing system according to the invention is characterized in that the pouch comprises a material ~-which is s~retched at least in a direction ~ransversely to the pouch's dispensing aperture, so that, upon relaxation of the pouch when tissues are removed from it, the pouch's dispensiFlg aperture retracts to lie substantially in the plane of the topmost tissue in the stack.
For easy dispensing of a tissue from a staek, i~ is desirable ~hat the topmost tissue is located relatively close to the dispensing apernlre. .
When the pouch is nearly empty, it is for pouches of larger si~e inconvenlent for a consumer to have to reach inside the pouch through the i.~'~, .
WO 93/17933 21 3 ~ 9 D 7 P~/us93/ol896 . . 9 dispensing apern~re. By providing a pouch which is stretchable, for ins~ance in a harmonica-like manner, and which contracts each time a tissue is dispensed from the pouch, the topmost tissue is located conveniently close to the dispensing aperture for both full pouches and for almost empty pouches.
Preferably the tissues are at their edges provided with a visual iIldicatior means for highlighting the edge with respect to the surface of the tissue.
Hereby the ease of use of the tisslles is increased. The visual indieation means can consist of a color, an embossment or a cut pa~tern.
A further embodiment of a storage and dispensing system according to the invention is characterized in ~hat the system comprises means for att~ching the pouch to the container for preventing movement of the pouch towards the container's dispensing aperture.
The attachment means can be a tape which is with one side permanently fixed to the bottom of the pouch and which is at its other side provided with a glue that is strong enough t~ fix the pouch to the bottom of the container, but which can be torn loose from-the container when the pouch is empty. A tape useful for fixing the pouch to ~he container is marketed by Tesa (Beiersdorf ~G) under the tradename Tes~film. The ma~erial of the pouch has to have a sufficient strength to prevent tearing upon removal of the empty pouch from the container. Another way of releasably fixing the pouch to the eontainer is with a t~pe system (Velcro tapes) of which one tape is provided wi~h flexible protrusions and which is stuclc to the bottom of the pouch or the bottom of the container. A
second tape is provided with hooks made of nylon or rayon fibers with which the protrusions engage. The second tape is fixed to either the pouch or ~he container, depending on where the tape having the protmsions is attached to. As an attachment means there could aiso be .:-provided one or a number of suction naps which are preferably affixed to the bottom of the container and which engage wi~h the smooth outer sur~ace of the pouch.

Detailed description of the d~awin~
Although in the givcn examples the pouch coIltains a stack of pre-moistened tissues, ~he storing and dispensing system is not limited thereto and can contain in general all produ~ts that tleed ~o be sealingly packed before use, such as for instance ground coffee or detergent powders.
Fig. 1 shows a storing and dispensing system 1 comprising a container 3 and a pouch 5. The pouch S co~tains a folded s~ack of pre-moistened tissues 6 and consists of a liquid impervious material. T ~min~tes for use in the pouch S can include polyethylene terephthalate (PET), polyethylene (PE~, polypropylene (PP), oriented polypropylene (OPP), aluminium (A1) and polyamide (PA) in the following combinations:
PFT/P~, PET/PP, OPP/PP, PET/Al/PP, OPP/Al/PE, metallized OPP/PEI cellophane/PE, PA/PE and PA/PP.
' 11 2131g~37 Useful paper-laminates include:
paper/PE, paper/PET/PE, paper/Al/PE~ paper/Al/PP,OPP/paper/PE, OPP/paper/PP1 PA/paper/PE, PA/paper/PP, cellophane/paper/PE, OPP/paper/A 1 /PE, OPP/paper/A 1 /PP, PET/paper/Al /PE, PET/paper/A 1 /PP.
The choice of laminates depends on the contents of the pouch and on the lifetime thereof.
The pouch 5 can be placed inside the container 3 through the container's dispensing opening 9 at the top. Before first time use the pouch 5 is sealed by a tab 7 whlch covers the pre-cut dispensing aperture 10. The part 1 1 ' that is cut out of the pouch's topface 11, pre~erably remains located between the tab 7 and the contents of the pouch 5. On first time use, the closed pouch can be placed inside the container 3 and the ~ab 7 can be removed from the dispensing apcrture 10. The tab 7 is glued to the pouch by an adhesive, or is heat-sealed to the pouch, with a relative low peeling strength such as to be easily remo~able. Upon storage of the opeIled pouch S inside the con~ainer 3, the container 3 is closed by a lid 12. The lid 12 is connected to a sidewall 13 of the container and engages, upon closing, the sidewalls of the container so as to ~rm a fluid-tight ~ seal. For improved stability of the container's outer walls, they are at their end face provided with a rim 15 that also functions as a seal. The container 3 can be made of any fluid-impervious material such as l~min~e~ cardboard or a material- such as, PYC, PP, PS, HDPE (high density polyethylene) or PET.
Since the pouch is stored inside the container 3, which in its closed s~a~e is fluid-tight and prevents drying out of the products contained in the pouch, the dispensing aperture 10 of the pouch can be relatively large and need not be reclosable. The tab 7 ~an in ~hat case be removed completely f~om the pouch. Removal of the tab 7 from the pouch 5 allows for easy :~
one-h~nrlef~ opening of the cont~iner 3 and dispensing of a tissue therefrom. Preferably the tab 7 iSl after removal from the pouch, -:
attachable to the inside of the lid 12 which forms a receiving surface. For easy re-attachment of the tab 7 to the pouch 5, it is preferred tha~ the tab 7 overlaps t~ie dispensing aperture 10 by a distance of at lease between 10 and 15mm. A glue which is easily releasable from the pouch 7 and the WO 93/17933 PCI/US93/0189~i lid 12 and which can be attached to the pouch repeatedly, is produced by MACtac S.A., Belgium. For good attachment, the inside of the lid 12 is srnooth at least ~or a surface area equal to the surface area of the ta~7.
The dispensing apernlre lO preferably is of oval shape and is located in the top~ace l l o~ the pouch 10, ~he peripheral edge 14 of the dispensing aperture being located within the periph~ral edge 16 of the topface 11 Since the parts of the topface l l located around the peripheral edge 14 restrain the edges of the topmost tissue in the pouch, this tissue is unfolded when pulled out of the pouch through the dispensing aper~re 10. If a maximum protection against drying out of the tissue is desi~ed, the dispensing aperture 10 can be in the form of a slit, although the ease of removing a tissue from the poueh in that case will be reduced.
For easy removal of the tissues from the pouch, it is, especially ir~ the case of a smaller dispensing aperture 10, advantageous if the surface of the tissue is in the p}ane of the dispensing aper~re or projects beyond this ---plane. Especially when little tiss~es are left in the pouch it can, in the ~:~
case of a small dispensing aperture and a relatively large pouch, be hard to get them out. When the pouch is made of flexible material which is stretched around the tissues in a direction transverse to ~he dispensing aperture lO, the pouch will decrease in si~e when the tissues are removed from it. Thereby the uppermost tissue will remain in the plane of the dispensing aperture 10. The pouch 5 caIl be stretched around the tissues upon filling. In case the pouch itsel~ is made of nsn-stretchable mate~ial, contraction of the pouch around the tissues can be obtained by connectiorl -of elastic members 17 along the sides of the poueh.
In the embodiment of figures 2 and 3, the t~b 7 is formed by the outer layer of the pouch. The tab 7 is Cllt-OUt in the pouch material and is glued to the inner layer 18 that is connected to the inside of the topface 11 of the pouch. The dispensing aperture 10 is pre-cut in the inner layer 18 along tbe peripheral edge 14, and is covered by the outer layer of the pouch and the part 18' of the layer 18. It is also possible that the layer 18 is a continuous layer that is l~rnin~te~ to all of the inside of the pouch S to form a gas-tight ba~rier. In this case, the dispensing aperture lO is formed by the pre-cut hole in the outer layer of the pouch 5.
WO 93/ 1 7933 2131 ~ 0 7 PCI'/US93/01 896 Preferably the tab 7 is at both ends provided with two protrusions 8 for easy opening by both right and left-handed users~ without having t~
change the orientation of the pouch. The protrusions 8 are not glued to the layer 18. When placed inside the cont~iner 3, it is preferred that the edges of the topmost ply of the upper tissue in the st~ck of tissues in the pouch, always ~aces away from the user. It has been found that easies~
dispensing occurs when a user can rest his fingers beyond the edge of the topmost tissue and can pull the tissue towards him. For this reason, the pouch will always be placed inside the container in a fixed orientation.
After the sealed pouch S has been placed inside the container 3, a left-handed user will grab the tab 7 at its right-hand side and pull it to the left whereas the right-h~ntterl user will grab the tab at the left-hand side, both users finding an easy grip.
Figure 4 shows a tissue 19 which has been folded so that one side flap 23 is on top of a central part 21 of the tissue and one side flap 24 is underneath the central part 21. ~n order to increase the Yisibility of the edge 25 of the side flap 23 against the central part 21, it is provided with a non-straight cut pattern, such as for instance a cunred pattern or a saw-too~h pattern. Alternatively, the edge 25 of the tissue 19 ~an be embossed, ~or instance with a pat~ern of dots or s~ripes. Another way to ;-:highlight the edge is ~o give the scraight cut edge, or the area next to it, a co}or which is sontrasting with the central par~ 21, as indicated by the shaded area of the topmost tissue of the stack 6 in figure 1.
In figure 5, the attaching me~nS for attaching the pouch to the bottom of the container comprise the glue tapes 27 and 29. The glue tapes 27 and 29 are double-sided and comprise a relatively strong glue at the side of attachment to the pouch. The side of the ~apes which is to engage the bottorn of ~he container 3, is covered with a glue that is strong enough to keep ~he pouch in place when tissues are pulled from the pouch 5. The side of the tape for engaging the bottom of the container is covered wi~h a release paper, that is remoYed from the tape when ~he pouch is placed in the container upon refill. It is~ depending on the materiai of the pouch, also possible to apply the glue for affixing the pouch to the con~ainer WO 93/17933 21 ~1 ~ 0 7 PCr/US93/01896 directly to the surface of the pouch 5, and to cover the glue by a release paper. . ~-Figure 6 shows alternative attachment means for affixing the pouch 5 tothe container 3. The attachment means comprise a tape 31 which is glued to the bottom of the pouch 5 and which has a surface of protmsions 35.
The hooks engage with loops 37 of a complementary t~pe 33 which is glued to the bottom of the container 3. Att~chment means of the above -~
mentioned kind ~re described in det~il in the American Patent US-A-5,058,247 Figure 7 shows a bo~tom view of the container, the anti-slip support :~
comprising four suction naps 39 which can engage wi~h a smooth and non-porous supporting sur~ace of the container.
Because the container is prevented to move along the supporting surfaceor to be lifted therefrom, the container can be opened using or~e hand only. For instance when the tissues consist af baby wipes, it is important that one hand of the user of the tissues can remain available ~or holding the baby while with the other hand the container can be opened and a tissue can be taken from i~.
Figure 8 shows another embodiment of the anti-slip support. The container is provided with openings 41 in its bottom. Upon placing the pouch S in the container, the glue tapes 27 or the glued areas project through the holes and at~ach to the supporting surface of the container. In this way, the movement of the pollch with respect to the container and the movement of the container with respect to its supporting surface are -~
preven~ed.

IN A SEALED POUCH
Field of the invention , The invention relates to a storing and dispensing system for a product paclced in a sealed poueh, the system cornprising:
- a container of relatively rigid matcrial having a dispensing openiIlg which is covered by a iid, the container bemg in its closed position sufficien~ly air-tight to prevent free excha~ge of air between the container's conteIlts and the ambient, and a sealed pouch in which a produc~ is contained, the pouch comprising a topface having opening means for m~n~l~lly opening the pouch, the pouch being a~ter opening thereof storable inside the cont~iner, the opening means comprising a pre-farmed dispensmg aperture which is openably sealed by a cover member which is removable from the~ dispensing ape~ture.
Backyround of the invention Such a system, wherein the pouch comprises pre-mois~ened tissues, is rnarketed by Scott Paper Co., Philadelphia, PA 19113, US~, under the tradç name 33aby Fresh.
In this system, a refill pouch made of l~min~te.~ polyethylene film contains a folded stack of wet baby wipes. On a ~op~ace of the pouch. the film is provided with a line of weakening, the top~ace ~eing covered by a glued-on eab that firmly adheres to ~he topface. To open the pouch, the ~ab is pulled so that the film of the pollch is ripped and the contents are exposed. To prevent the moist tissues ~rom drying out, they can be taken from the pouch and placed inside a box-shaped piastic container. It is W0 93/17933 Pcr/US93/01896 ' 2l319~72 .-'''' ~:,, also possible to place the opened pouch inside the eontainer as is shown in instructions on the pouch.
The above described refill system has as an advantage that by multiple use of the container, the waste coming from used-up product is reduced.
Upoi1 opening of the pouch however, the top~ace and the side face of the pouch are torn in a relatively irregular manner, so that the sides of the stack of tissues are e~posed. Upon dispensing of the stack's topmost -tissue from the container~ the underlying tissues can accidentally be touched so that the hygienic conditions of those tissues deteriorates.
Because the moist ~issues san through the rip in the pouch contact the inside of the container, the container can in eourse of time be con~min~ted by the mois~ure of the tissues.
A s~oring and dispensing system containing a pouch which has a F~e- -~
formed dispensing apernlre is known from the European patent application EP-A-O 370 192.
:
In this patent application a paperboard box is described for storage and dispensin~g of a stack of moist ~iss~es. The paperboard box has a dispensing opening which is covered by a paperboard lid that can be opened along a pre-perforated line. The paperboard box is at its inside provided with a fluid-impervious layer of polyethylene, whieh is opened at the same time as the box is opened. In another embodiment~ the paper~oard box is provided with a liquid impervious, sealed, inner poueh in which the napkins are contained. The pouch is in the area of the dispensing opening of the ~ox affixed to the inside of the box. The inner pouch can be opened by tearing loose a tab which remains at one end fixed,to the pouch and which can be folded baek over the p~uch's aperture ~or reclosure.
:..
The storing nd dispensing system of this kind is not fit for multiple use, no refill being possible after the con~ents of ~he box have been used. Also is the recloseability of the known system limited sance the tab of the pouch, that functions as a sealing lid a~er first time opening, rests on the peripheral edge of the dispensing aperture in a non-sealing manner. ~ ~~
WO 93J17933 21 31 9 f3 7 PCr/US93/01896 , In the French patent FR-A-~ 376 802, a pouch containing moist tissues is disclosed, in which an oval shaped line of weakening is provided in the topface of the pouch. The topface of the pouch is covered by an adhesive label which upon removal tears the topface along the line weakening. the pouch material which is stuck to thc bottom of th~ adhesiYe label is removed from the pouch together with the label and a well-defined dispensing apern~re is formed after opening. The pouch can be stored in a container.
Ob;ects of the invention It is an object of the invention to pro~ide for a s~orage and dispensing system for products packed in a sealed pouch, wherein the arnoun~ of waste from used paclcaging material is reduced, which allows easy handling and in which hygienic conditions prevail.
It is another object of the invention to provide for a storage and dispensing system that allows for easy dispensing of the products from the pouch after placement inside the container and in which con~min~tion of the con~ainer by the contents ~rom the pouch, and vice versa, is prevented.
It is a filrther ob3ect of the invention to provide a storage and dispensing system in which the pouch after opening a~ter first time use, can be easily transported without the container.
It is again another obje~t of the invention to provide a storing and dispensing system which can be stably positioned and is suitable for being usedi single-handedly.
It is a still filrther object of the invention to provide a storing and ~ -dispensing system which is sui~able ~or cont~ in~ vacuum packed granular products.
Summary of the invention wo 93/ ~ 7933 ~ 1 3 1 3 0 7 Pcr/lJss3/01 a96 -~ -A storing and dispensing system according to the invention is characterized in that the cover member can be comple~ely detached from :
the pouch without substantially damaging the cover member or the pouch, the cover member comprising an adhesive adapted for adhesively ; .
refastening the cover member over the dispensing aperture subsequent to detachment of the cover member. -Because of the pre-formed dispensing apernlre in the ~opface of the pouch, ripping of the pouch upon removal of the t~b fr~m the top~ace~ is prevented. The clearly defined dispensing aperture, which can be formed by a cut in the pouch or by a line of weakening, does after opening not allow access to the tissues located underneath the topmost tissue. Since the pouch is, upon opening, not ripped in an arbitrary manner, the conten~s do not spill from the pouch upon placing of it in the container or upon dispensing product from the pouch when i~ is placed inside the container. This is especially important when the pouch contains a granular product such as ground coffee or detergent powder, which, in c~se the pouch is ripped upon opening, is easily spilled there~rom.
The c~ver member can after opening of the pouch ~e removed from the pouch's surface and can be ~t~cherl to a receiving sur~ace of the container. In thi~ way the cover membér's adhesive is protected from dust or other cont~n1in~tion. When the pouch is to be reclosed for transport, the cover mem~er can be detached from the container's receiving surface and re-applied to the pouch. Transporting the pouch without the conta~ner is often convenient due to the better conformability ~:-of ~he pouch compared to the relatively rigid container. Also, if some of -~he contents ~rom the pouch have been used, the pouch can be compressed to a smaller volume than the container.
After removal of the cover member from the pouch, it is advantageous to stick the cover member to the inside of the cont~iner's lid, so that each time upon opening of the container, the text or symbols of the label, which can comprise instructio~is ~or use, can be viewed by the user. It is important that the surface of the pouch to which the cover member is attached is of sufficient smoothness for the glue of the eover member to be easily released therefrom. The same applies for the container's 3 PCI/US93/0189~
5 ~1319 0~ ~
sur~ace to which the cover member is attached after removal from the pouch.
~.
A glue suitable ~or use on the cover member is produced by MACtac Europe SA, Boulevard Kennedy 7060 Soignies, Belgium~ under type number MR980. Especially when the pouch contains moistened tissues, such as we~ baby wipes~ it is desirable that the pouch can be transported without the con~ainer, which due to its rigidaty often cannot very easily be han~led during transport. By allowing the cover member to be removed ~rom the container and re-fastened across the dispensing aperture~ the s~oring and dispensing system according to the invention combines the advantages of a reclosable and easi}y transportable travel pack with the easy dispensing facility and good sealing properties of a cont~iner and its refill pack.
Another embodiment of a storing and dispcnsing system according to the invention is characterized in that the cont iner is provided with an anti-slip support for exer~ing a ~orce on the container for preventing movemen~ of the container in a direction perpendicular and/or parallel to a supporting surface on which the cont~iner is placeable.
The anti-slip support can comprise a number of suction rlaps Velcro tapes or glue tapes engaging the supporting surface. It can also comprise a hole in the bottom of ~he container through which a part of the glue tape tha~ is attached to the pouch, for restriction of movement of the youch with respect to the container, can project and can contact the supporting surface. When the container is unable to move with respect to its supporeing surface, both in a direction parallel and perpendicular to ~he supporting s~rface, the container ~an be opened and a ~issue can be dispensed from the pouch by a user while only using one hand. Also the rislc of tipping over the container when most of the tissues have been :~
used, the container having at that time a rcduced weight and reduced stability, is reduced when fixing the container to the supporting surf2ce.
A further embodiment of a storing and dispensing system accQrding to the invention is characterized in that the product cont~ined in the pouch is of a granular nanIre.
wo 93/17933 Pcr/uss3/0l8s6 21319~ 6 It is known from EP-A-O 467 481 to pack ~ranular dctergents in a compact form~ by packing the detergent in a pouch under vacuum, or by ~: -packing detergents in a heat shrinkable foil which is shrunk to compress the detergent. Another way of compact packaging of products, comprises packing the products in a pouch under compression. In a similar m~nner it is known to pack ground coffee in a pouch under vacuum.
It was found that for granular products, ra~her than pouring these products, after opening of the pouch, into the container, it as preferred to plaLce the pouch containing the granular product inside the container. This will reduce the chance of spilling of product. Also, the sealing properties of the pouch will be partly maintained so that better protection of the product against drying out or loss of arorna is provided compared to when the pouch is absent. Providing a pre-formed dispensing aperture in the pouch containing granular products prevents the pouch from ripping in an arbitrary manner upon opening and reduces the chance of spilling of the granular products from the pouch into ~he container.
.
For granular products that are paeked under vacuum7 it is essential that an airtight seal is formed by the cover member overlying the daspensing :
apernlre. For products that are packed under compression, the cover member must be su~lciently strong to adhere to the pouch without the expansion forces of the packed produet det~ching the cover member.
,..~., Again another esnbodiment of a storing and dispensing system according ~o the inYention is characterized in that the pre-formed dispensing aperture comprises a peripheral edge, the dispensing aperture exclusively extending in the plane of orle face of the pouch so that upon placing of the pouch in the container, the dispensing aperture is parallel with the dispensing opening, the peripheral edge of the dispensing apernlre at most partly coinciding wi~h a circumferential edge of the topface.
The dispensing aperture of the pouch is confined to lie in only one face of the pouch and is of smaller size than this face. Wherl the pouch contains pre-moistened tissues, ~he pouch material of the topface surrounding the dispensing apernlre covers the edges of the moist tissues that lie W~ 93/~7933 PCI'/US93/01896 underneath this pouch material and restricts movement thereof. Upon pulling the topmost tissue from the st~ck through the dispensing aperture, the restriction of ~he tissues' edges by the peripheral edge, cause t~e tissues to unfold from their flattened state. The edges of the topface surrounding the dispensing aperture prevent the sid~faces of the pouch from collapsing and prevent, in case the pouch contains a granular pro~uct, spilling of the granular contents into the container. The dispensing aperture is preferably elliptical, but can be round or rectangular.
Qgain another embodiment of a storing and dispensing system according to ~he inventiorl is characterized in that the dispensing aperture is formed by a hole extending through the topface of the pouch or by an endless line of weakening, the dispensing aperture being covered by a tab of larger size than the dispensing aperture, the tab being connected to the pouch along the peripheral edge of the dispensing aperture.
The dispensing ape~ture of the pouch is before first time use covered by a sealing tab that can be glued over the dispensing aperture and tha~ can be easi~y removed therefrom. Prefierably a peeling force of the tab does not exceed between 0.8 and 1.2 N/cm. Use~ul materials for the tab comprise Polyvinyl chloride, polyethylene, polyethylene tereph~h~l~te, polypropyl~ne and polystyrene, either as single layers or l~rnin~te-~ in cornbination. :
Again another embodiment of storing and dispensing system according to the invention is ct~aract~rized in that the pouch comprises a l~min~te of at least two layers, an outer layer comprising the dispensing aperture, the inner layer being continuous and covering the dispensing apernlre, the opening me~n.~ comprising a tab that within the boundaries of the dispensing aperture is connected to the inne~ layer which is sufficiently ~ .
thin to be ~orn upon removal of the tab from the dispensing apernlre.
An airtight pouch that can be easily opened is made by ~orming the po~lch's dispensing aperture in a first layer ~that can for instance consist of aluminium) by pre-cutting a hole therein or by providing a pre-formed line of weakening, and by subsequently l~min~ing a second layer (for wo 93/17933 2 1 3 1 ~ 0 7 Pcr/uss3/olgg6 " ~
instance polyethylene) with the first layer. In case a hole is pre-cut in the first 1ayer, the second layer, which is before opening of the pouch a continuous layer, prevents contact of the contents of the pouch and~the tab that is glued over the dispensing aperture for opening. Pouches of this kind are especially useful for containing aseptic products. A method for producing a lamin~e of two layers, one of which having a pre-cut aperture or a pre-formed line of weakening, is disclosed in the European patent application EP-A- 191525, which is incorpora~ed herein by reference.
Another embodiment of a storing and dispensing system accQrding to the invention is characterized in that the pouch comprises a l~min~te of at east two layers, an inner layer comprising the dispensing apern~re which is formed by a hole extending thr~ugh the inner layer or by an endless Iine of weakening, the dispensing aperture being covered by a tab of -~
larger si~e, the tab being an integral part of the outer layer of the pouch ~:~
and being formed by a cu~ or a line of weakening in the outer layer.
The inncr layerpreven~s con~ct of mois~re from the pouch's contents withthe cut or the line of weakening in the outer layer of the pouch.
Especial~yifthe pouchis made ofa paper l~min~te, theinnerlayer prevents migration of liquid into the paper. Also, sincethe outerlayer of the pouch functions as the label, a single printing step su~fices for providingthe ou~ide ofthe pouch withinstructions for opening and/or decorative prin~ing. No extra prin~ing of a separate label is necessary.
Again another embodiment of a storing and dispensing system according to the invention is characterized in that the pouch comprises a material ~-which is s~retched at least in a direction ~ransversely to the pouch's dispensing aperture, so that, upon relaxation of the pouch when tissues are removed from it, the pouch's dispensiFlg aperture retracts to lie substantially in the plane of the topmost tissue in the stack.
For easy dispensing of a tissue from a staek, i~ is desirable ~hat the topmost tissue is located relatively close to the dispensing apernlre. .
When the pouch is nearly empty, it is for pouches of larger si~e inconvenlent for a consumer to have to reach inside the pouch through the i.~'~, .
WO 93/17933 21 3 ~ 9 D 7 P~/us93/ol896 . . 9 dispensing apern~re. By providing a pouch which is stretchable, for ins~ance in a harmonica-like manner, and which contracts each time a tissue is dispensed from the pouch, the topmost tissue is located conveniently close to the dispensing aperture for both full pouches and for almost empty pouches.
Preferably the tissues are at their edges provided with a visual iIldicatior means for highlighting the edge with respect to the surface of the tissue.
Hereby the ease of use of the tisslles is increased. The visual indieation means can consist of a color, an embossment or a cut pa~tern.
A further embodiment of a storage and dispensing system according to the invention is characterized in ~hat the system comprises means for att~ching the pouch to the container for preventing movement of the pouch towards the container's dispensing aperture.
The attachment means can be a tape which is with one side permanently fixed to the bottom of the pouch and which is at its other side provided with a glue that is strong enough t~ fix the pouch to the bottom of the container, but which can be torn loose from-the container when the pouch is empty. A tape useful for fixing the pouch to ~he container is marketed by Tesa (Beiersdorf ~G) under the tradename Tes~film. The ma~erial of the pouch has to have a sufficient strength to prevent tearing upon removal of the empty pouch from the container. Another way of releasably fixing the pouch to the eontainer is with a t~pe system (Velcro tapes) of which one tape is provided wi~h flexible protrusions and which is stuclc to the bottom of the pouch or the bottom of the container. A
second tape is provided with hooks made of nylon or rayon fibers with which the protrusions engage. The second tape is fixed to either the pouch or ~he container, depending on where the tape having the protmsions is attached to. As an attachment means there could aiso be .:-provided one or a number of suction naps which are preferably affixed to the bottom of the container and which engage wi~h the smooth outer sur~ace of the pouch.

Detailed description of the d~awin~
Although in the givcn examples the pouch coIltains a stack of pre-moistened tissues, ~he storing and dispensing system is not limited thereto and can contain in general all produ~ts that tleed ~o be sealingly packed before use, such as for instance ground coffee or detergent powders.
Fig. 1 shows a storing and dispensing system 1 comprising a container 3 and a pouch 5. The pouch S co~tains a folded s~ack of pre-moistened tissues 6 and consists of a liquid impervious material. T ~min~tes for use in the pouch S can include polyethylene terephthalate (PET), polyethylene (PE~, polypropylene (PP), oriented polypropylene (OPP), aluminium (A1) and polyamide (PA) in the following combinations:
PFT/P~, PET/PP, OPP/PP, PET/Al/PP, OPP/Al/PE, metallized OPP/PEI cellophane/PE, PA/PE and PA/PP.
' 11 2131g~37 Useful paper-laminates include:
paper/PE, paper/PET/PE, paper/Al/PE~ paper/Al/PP,OPP/paper/PE, OPP/paper/PP1 PA/paper/PE, PA/paper/PP, cellophane/paper/PE, OPP/paper/A 1 /PE, OPP/paper/A 1 /PP, PET/paper/Al /PE, PET/paper/A 1 /PP.
The choice of laminates depends on the contents of the pouch and on the lifetime thereof.
The pouch 5 can be placed inside the container 3 through the container's dispensing opening 9 at the top. Before first time use the pouch 5 is sealed by a tab 7 whlch covers the pre-cut dispensing aperture 10. The part 1 1 ' that is cut out of the pouch's topface 11, pre~erably remains located between the tab 7 and the contents of the pouch 5. On first time use, the closed pouch can be placed inside the container 3 and the ~ab 7 can be removed from the dispensing apcrture 10. The tab 7 is glued to the pouch by an adhesive, or is heat-sealed to the pouch, with a relative low peeling strength such as to be easily remo~able. Upon storage of the opeIled pouch S inside the con~ainer 3, the container 3 is closed by a lid 12. The lid 12 is connected to a sidewall 13 of the container and engages, upon closing, the sidewalls of the container so as to ~rm a fluid-tight ~ seal. For improved stability of the container's outer walls, they are at their end face provided with a rim 15 that also functions as a seal. The container 3 can be made of any fluid-impervious material such as l~min~e~ cardboard or a material- such as, PYC, PP, PS, HDPE (high density polyethylene) or PET.
Since the pouch is stored inside the container 3, which in its closed s~a~e is fluid-tight and prevents drying out of the products contained in the pouch, the dispensing aperture 10 of the pouch can be relatively large and need not be reclosable. The tab 7 ~an in ~hat case be removed completely f~om the pouch. Removal of the tab 7 from the pouch 5 allows for easy :~
one-h~nrlef~ opening of the cont~iner 3 and dispensing of a tissue therefrom. Preferably the tab 7 iSl after removal from the pouch, -:
attachable to the inside of the lid 12 which forms a receiving surface. For easy re-attachment of the tab 7 to the pouch 5, it is preferred tha~ the tab 7 overlaps t~ie dispensing aperture 10 by a distance of at lease between 10 and 15mm. A glue which is easily releasable from the pouch 7 and the WO 93/17933 PCI/US93/0189~i lid 12 and which can be attached to the pouch repeatedly, is produced by MACtac S.A., Belgium. For good attachment, the inside of the lid 12 is srnooth at least ~or a surface area equal to the surface area of the ta~7.
The dispensing apernlre lO preferably is of oval shape and is located in the top~ace l l o~ the pouch 10, ~he peripheral edge 14 of the dispensing aperture being located within the periph~ral edge 16 of the topface 11 Since the parts of the topface l l located around the peripheral edge 14 restrain the edges of the topmost tissue in the pouch, this tissue is unfolded when pulled out of the pouch through the dispensing aper~re 10. If a maximum protection against drying out of the tissue is desi~ed, the dispensing aperture 10 can be in the form of a slit, although the ease of removing a tissue from the poueh in that case will be reduced.
For easy removal of the tissues from the pouch, it is, especially ir~ the case of a smaller dispensing aperture 10, advantageous if the surface of the tissue is in the p}ane of the dispensing aper~re or projects beyond this ---plane. Especially when little tiss~es are left in the pouch it can, in the ~:~
case of a small dispensing aperture and a relatively large pouch, be hard to get them out. When the pouch is made of flexible material which is stretched around the tissues in a direction transverse to ~he dispensing aperture lO, the pouch will decrease in si~e when the tissues are removed from it. Thereby the uppermost tissue will remain in the plane of the dispensing aperture 10. The pouch 5 caIl be stretched around the tissues upon filling. In case the pouch itsel~ is made of nsn-stretchable mate~ial, contraction of the pouch around the tissues can be obtained by connectiorl -of elastic members 17 along the sides of the poueh.
In the embodiment of figures 2 and 3, the t~b 7 is formed by the outer layer of the pouch. The tab 7 is Cllt-OUt in the pouch material and is glued to the inner layer 18 that is connected to the inside of the topface 11 of the pouch. The dispensing aperture 10 is pre-cut in the inner layer 18 along tbe peripheral edge 14, and is covered by the outer layer of the pouch and the part 18' of the layer 18. It is also possible that the layer 18 is a continuous layer that is l~rnin~te~ to all of the inside of the pouch S to form a gas-tight ba~rier. In this case, the dispensing aperture lO is formed by the pre-cut hole in the outer layer of the pouch 5.
WO 93/ 1 7933 2131 ~ 0 7 PCI'/US93/01 896 Preferably the tab 7 is at both ends provided with two protrusions 8 for easy opening by both right and left-handed users~ without having t~
change the orientation of the pouch. The protrusions 8 are not glued to the layer 18. When placed inside the cont~iner 3, it is preferred that the edges of the topmost ply of the upper tissue in the st~ck of tissues in the pouch, always ~aces away from the user. It has been found that easies~
dispensing occurs when a user can rest his fingers beyond the edge of the topmost tissue and can pull the tissue towards him. For this reason, the pouch will always be placed inside the container in a fixed orientation.
After the sealed pouch S has been placed inside the container 3, a left-handed user will grab the tab 7 at its right-hand side and pull it to the left whereas the right-h~ntterl user will grab the tab at the left-hand side, both users finding an easy grip.
Figure 4 shows a tissue 19 which has been folded so that one side flap 23 is on top of a central part 21 of the tissue and one side flap 24 is underneath the central part 21. ~n order to increase the Yisibility of the edge 25 of the side flap 23 against the central part 21, it is provided with a non-straight cut pattern, such as for instance a cunred pattern or a saw-too~h pattern. Alternatively, the edge 25 of the tissue 19 ~an be embossed, ~or instance with a pat~ern of dots or s~ripes. Another way to ;-:highlight the edge is ~o give the scraight cut edge, or the area next to it, a co}or which is sontrasting with the central par~ 21, as indicated by the shaded area of the topmost tissue of the stack 6 in figure 1.
In figure 5, the attaching me~nS for attaching the pouch to the bottom of the container comprise the glue tapes 27 and 29. The glue tapes 27 and 29 are double-sided and comprise a relatively strong glue at the side of attachment to the pouch. The side of the ~apes which is to engage the bottorn of ~he container 3, is covered with a glue that is strong enough to keep ~he pouch in place when tissues are pulled from the pouch 5. The side of the tape for engaging the bottom of the container is covered wi~h a release paper, that is remoYed from the tape when ~he pouch is placed in the container upon refill. It is~ depending on the materiai of the pouch, also possible to apply the glue for affixing the pouch to the con~ainer WO 93/17933 21 ~1 ~ 0 7 PCr/US93/01896 directly to the surface of the pouch 5, and to cover the glue by a release paper. . ~-Figure 6 shows alternative attachment means for affixing the pouch 5 tothe container 3. The attachment means comprise a tape 31 which is glued to the bottom of the pouch 5 and which has a surface of protmsions 35.
The hooks engage with loops 37 of a complementary t~pe 33 which is glued to the bottom of the container 3. Att~chment means of the above -~
mentioned kind ~re described in det~il in the American Patent US-A-5,058,247 Figure 7 shows a bo~tom view of the container, the anti-slip support :~
comprising four suction naps 39 which can engage wi~h a smooth and non-porous supporting sur~ace of the container.
Because the container is prevented to move along the supporting surfaceor to be lifted therefrom, the container can be opened using or~e hand only. For instance when the tissues consist af baby wipes, it is important that one hand of the user of the tissues can remain available ~or holding the baby while with the other hand the container can be opened and a tissue can be taken from i~.
Figure 8 shows another embodiment of the anti-slip support. The container is provided with openings 41 in its bottom. Upon placing the pouch S in the container, the glue tapes 27 or the glued areas project through the holes and at~ach to the supporting surface of the container. In this way, the movement of the pollch with respect to the container and the movement of the container with respect to its supporting surface are -~
preven~ed.
Figure 9 shows a contailler 3 in the form of a flat cylinder. The bottom . -face of the cylinder forms the refill opening through which the pouch Gan r -be inserted. The refill opening is coverable by a lid 43. The lid 43 can be screwed Oll by engaging a screw threa~ 49 on the outside of ~he container wi~h a groove, which is not shown in the drawing, on ~he inside of ~he lid 43; The topface 47 of the cylinder is provided with a lid 12 2131907 -';
WO 93/17933 PCl/US93/01896 ' which is connected ~o the topface 47 along a hinge line 45. The lid 12 covers the dispensing apernlre 9 of the cylinder.
