Abstract
A system is provided for dispensing fluids comprising a housing and a flexible refill pouch (1), whereby the housing comprises a reservoir (2) into which the pouch can be positioned, and which contains a piercing member (5) tightly connected to the bottom part thereof and projecting therefrom outwardly into said reservoir, and further a platform (3) for positioning the pouch which platform is movably attached around the piercing member to the bottom part of the reservoir such that it will move down into the direction of said bottom part when a full pouch is placed onto it and will return to its original position when the pouch becomes empty. This system can be effectively operated with a blunt piercing member (6).
Description
W O 96/26312 PCTAEPg6JO0678 ~IOUID DISPENSING ~Y~'l'h'~
TECHNICAL FIELD OF THB lNv~NllON
The present invention is concerned with a system for 5 dispensing liquid product, in particular liquid detergent product, from a refill pack. The dispensing system o~ the invention is particularly suitable for use in combination with a dosing pump for dosing said liquid detergent product into a washing machine.
BACKGROUND OF l~IE lNV~'N'l'lON
Dispensing systems of the above-indicated kind have been described in the artO
For example, EP-A-014,805 discloses a system for dispensing 15 a liquid product comprising a flexible refill pouch con-t~;n;ng said liquid and a refill reservoir for positioning said pouch. Furthermore~ said reservoir comprises a pier-cing member which is suitable for penetrating the pouch when it is positioned in the refill reservoir.
20 It was found that the piercing member needs to contain a sharp knife for easy operation of such a dispensing system.
As a consequence, this type of dispensing systems is poten-tially hazardous in that there is a significant risk of operating people injuring themselves.
We have now surprisingly found a new type of liquid dispen-sing system which can be effectively operated with a blunt piercing member, thus considerably reducing the above-in-dicated risk.
DEFINITION OF THE lNv~NllON
Accordingly, the present invention provides a system for dispensing fluid, comprising a housing and a flexible refill pouch, whereby the housing comprises a reservoir 35 into which the pouch can be positioned, and which contains a piercing member tightly connected to the bottom part W O96/26312 PCT/~I~C~_C78 thereof and projecting therefrom outwardly into said reservoir, characterised in that said reservoir further contains a platform for positioning the pouch which plat-form is movably attached around the piercing member to the 5 bottom part of the reservoir such that it will move into the direction of said bottom part when a full pouch is placed onto it and will return to its original position when the pouch becomes empty.
10 DETAI~ED DESCRIPTION OF THE lNv~NllON
The movable platform is generally a plate having an opening of sufficient size for achieving its movability around the piercing member. The effect of the movable platform present in the system of the invention is that it will move lS downward under the weight of a fresh completely ~illed refill pouch when said pouch is placed onto it. It was found that, as a result of this downward movement, the pouch will be easily penetrated by the piercing member, more easily than when the movable platform were not present 20 in the system of the invention.
Without wishing to be bound by theory, it is believed that said ph~nQm~no~ of easy penetration is caused by increased tension build-up in the flexible film material of which the 25 pouch is made, resulting from the movement of the platform.
In other words, it appears that the film material of the fresh pouch cannot fowl itself around the piercing member -or indeed only to a minor extent - when the pouch is positioned on to the platform, whereas said fowling 30 behaviour of the pouch is present to a much larger extent when the platform is absent.
Because of this ph~nnmenon of easy penetration, piercing members with both sharp and blunt knifes can be effectively 35 used. In view of the above mentioned reduced risk of in-jury, piercing members with blunt knifes are preferred.
WO 96126312 PClrJ~ ûC78 For easy operation of the movable platform, knife-shaped pierciny members are desirably applied. Piercing members having widely varying shapes and configurations, such as those having a triangle shape or cont~;n;ng a curved blade, S may be effectively used, provided that these members have an oblong pyramid-type shape so as to enable the platform to move downward around them thereby creating a suf-ficiently large hole in the pouch for the liquid to smooth-ly flow out. Preferably, the piercing member is positioned 10 at the central axis of the reservoir such that its own lon-gitll~; nA 1 axis coincides with this central axis.
The reservoir cont~; n; ng the movable platform may have a rectangular or a circular cross-section. For practicle 15 rea80ns, the movable platform present therein is preferably a plate of which the outer shape corresponds with the internal cross-section of the reservoir.The opening in the platform ha~ preferably a round shape.
20 Preferably, the pouch is not only flexible but also disposible. Flexible films made of one single layer as well as multilayer films can be suitably used as pouch material.
Examples of such sui~able materials are polypropylene and polyethylene.
A movable platform having suitable movability can be ob-t~; n~ by the application of both springs and an hydraulic system. For economic reasons, a spring-loaded platform which is connected to the bottom of the reservoir by way of 30 springs, is preferred.
J It is desirable that during operation of the dispensing system of the invention the pouch is completely emptied and that no residue is left behind therein.
35 In order to achieve this, the piercing member is preferably provided with one or more ret~; n; ng hooks. These hooks keep CA 022ll847 l997-07-28 W O96/26312 PCTI~l,''~OC78 the film of the pouch in a fixed position around the penetration hole while the movable platform is gradually moving upward by decompression of the springs when liquid is flowing out of the pouch, thus creating a funnel around 5 the penetration hole and allowing all the liquid to flow out of the pouch. For facilitating the formation of this funnel, the platform is preferably funnel-shaped.
The system of the invention is particularly suitable for 10 use in combination with a dosing pump for dosing the liquid poured out of the pouch into the reservoir. When said liquid is a liquid detergent product, the dosing pump may be effectively used for dosing said liquid into a washing machine.
The invention is further illustrated by Figures 1-3 which show schematic cross-sectional views of the dispensing system of the invention at consecutive stages when operating the system.
20 Referring more in detail to the drawings, in Figure 1 (1) indicates a flexible pouch filled with liquid. Also a reservoir (2) is shown, cont~;n;ng a spring-loaded platform (3) attached to the bottom of the reservoir by springs (4) and movable in the verticle direction around a piercing 25 member (5) having a blunt knife (6) on its upper side.
Figure (1) depicts the first step when operating the sys-tem, i.e. the step in which the pouch is put into the reservoir (2) and just before it is positioned onto the platform (3).
Figure 2 shows the second step, wherein the platform has moved down under the weight of the pouch (1) and the blunt knife (6) has penetrated the film material of the pouch, thus creating a hole through which the liquid can move out 35 of the pouch into the reservoir.
W 096/26312 PcT/~r~v~c78 Finally, Figure 3 shows the situation in which at least part o~ the liquid in the pouch has ~lown out causing the pouch to loose weight and the platform to move upward by the action of the springs. It can be seen that ret~; n; ng 5 hooks (7) keep the f ilm o~ the pouch surrounding the penetration hole fixed in the lowest position thus creating a funnel centered around this hole and allowing all the liquid to flow out o~ the pouch.
10 It is ~m~ ized that the system shown in the Figures illustrates a only pre~erred embodiment of the invention and that various constructional alternatives will be im-me~; ~ tely evident to the man skilled in the art, without departing from the scope of the present invention as 15 described in the claims.
