Description

FIELD OF THE INVENTION

The present invention relates to a device for storing and squeezing collapsible containers, said containers having at least one dispensing outlet.

The invention also relates to a kit of parts, comprising a reusable container storing device and at least one collapsible container having a dispensing outlet.

BACKGROUND OF THE INVENTION

Collapsible containers such as, for example, sachets or pouches are becoming increasingly popular packaging forms for pourable or squeezable products because they can be cheaply manufactured and are of low weight. Many collapsible containers, particularly containing liquid or squeezable food products, comprise resealable dispensing outlets to allow for the dispensing of multiple portions of the content of the containers. These type of containers are frequently used for food products such as mayonnaise or ketchup and also for personal care products such as toothpastes, washing liquids, shampoos or liquid soaps.

A disadvantage in using such collapsible containers is that the contents are often not very easily dispensed, particularly, when the container is nearly empty. Another disadvantage of collapsible containers is that they often lack the rigidity to be conveniently stored, transported, handled and/or displayed. Particularly, difficulties in stably storing such containers in the upright position as opposed to lying them down on the shelves, both in commercial use, e.g. on supermarket shelves as well as in the home, is a commonly encountered problem.

In order to try to overcome the lack of instability, collapsible containers have been manufactured which comprise either reinforcements or rims to enable the containers to stand on their own. This however, has the disadvantage that it increases the manufacturing costs for the container but it still does not provide suitable stability for upright storage. Furthermore, it increases the amount of packaging material which is becoming increasingly undesirable for environmental reasons. Holders have also been developed to try to overcome some of the problems outlined above.

U.S. Pat. No. 2,903,161 discloses a bag supporter and bag content dispenser comprising two elongated side portions, means movably attaching together said side portions, means for engaging and upholding a bag disposed between the side portions and tearing means.

Although U.S. Pat. No. 2,903,161 provides a solution to some of the problems described above, there is still a need for a device for storing and squeezing a collapsible container (such as a sachet or a pouch) that meets most or all of the following criteria:

it allows the storage of the collapsible container in an upright position without requiring excessive storage space (shelf space), it offers at least some protection from physical damage to the container, it is of simple construction and/or has only a minimal number of components, it is cheaply manufactured—ideally from a unitary body of a flexible material, it allows the contents of the container to be easily dispensed without leaving a large amount of the contents which cannot be dispensed from the container (ideally by single-handed use), and/or it is reusable.

The device provided by the invention disclosed herein solves or at least reduces most or all of the problems listed above.

SUMMARY OF THE INVENTION

The present invention provides according to a first aspect a device for storing and squeezing a collapsible container having at least one dispensing outlet, the device comprising two opposing bodies wherein at least one of the bodies comprises an aperture through which the outlet of the container passes, the bodies being hingedly linked to accommodate the container such that the exertion of pressure on one or more of the bodies moves the bodies towards each other to squeeze the container, the device further comprising means to enable the device to stand.

According to a second aspect the present invention provides a kit of parts comprising a device according to any one of claims 1 to 11 and a collapsible container, said container having a dispensing outlet.

DETAILED DESCRIPTION OF SOME NON-LIMITING EMBODIMENTS OF THE INVENTION

A device according to the invention is a holder for storing and squeezing a collapsible container wherein the container has at least one dispensing outlet. The container has an upper part and a lower part. The upper part of the container is defined as the portion of the container wherein the dispensing outlet is situated. [0012]
Although the device can be used for any type of conventional collapsible container, preferred containers according to the invention are pouches or sachets. Preferably, the containers are containers for liquid or squeezable food products, or personal care products e.g. tooth-paste, shampoos and washing liquids. The dispensing outlet of the container is preferably a resealable outlet. Preferably, the body of the container is wider than the outlet. If the resealable outlet is covered by a lid, it is preferred that the lid does not cover the entire outlet but leaves part of the outlet Between lid and body of the container accessible for an engagement means. [0013]
The device comprises at least two opposing bodies that are hingedly linked. At least one of the bodies has an aperture. When inserting the collapsible container into the device, the container is placed between the opposable bodies of the device and the outlet of the container is passed through the aperture. Generally, the outlet extends beyond the perimeter of the opposing bodies or extends beyond the perimeter of at least of one of the exposing bodies. [0014]
Hingedly linked as used herein is understood to mean to mean to allow the movement of the bodies towards and away from each other as if they were attached to each other by means of a hinge. An actual hinge may be used but any means fulfilling the same purpose as a hinge may also be used. [0015]
Suitable examples therefor are membranes, films, folds or a thinned section in a unitary piece of material. For example, the two bodies may be formed from a unitary body of plastics material, which at some point is reduced in thickness so as to allow opposable movement of the parts separated by the reduced thickness section along that section. [0016]
Preferably, the device is configured such that the opposing bodies are hingedly linked at the upper part of the device when the device stands in an upright position. Preferably, the opposing bodies are configured (with respect to aperture and hingedly linkage) such that the upper part of the container after being accommodated between the bodies comes to rest at, or near, the hinged linkage of the bodies. [0017]
At least one of the bodies comprises an aperture through which the outlet of the collapsible containers passes. Generally, the aperture is at, next, or close to, the part of the device where the opposing bodies are hingedly linked. Preferably, the aperture is at the upper part of the device, when the device stands in an upright position. The aperture is shaped such that the outlet of the container can pass through it. Generally, the aperture is at least of the same width as the outlet of the container but smaller than the body of the container. [0018]
The opposing bodies can be made of a single piece of a material, or, they can be made of multiple, separated pieces. The opposing bodies may be smooth, roughened or textured on the inside and/or on the outside in order to facilitate handling and/or use. [0019]
Preferably, at least one the opposing bodies is flexible, more preferably all bodies are flexible. [0020]
The bodies may be of any shape. Preferably they are elongated. Most preferably they are of substantially the same length as the collapsible container. Preferably, at least one of the bodies is wider than the collapsible container. [0021]
The device further comprises standing means. [0022]
The standing means can be any means known in the art that enables the device to be stood upright. [0023]
A means to enable the device to stand may be an integral part of at least one of the opposing bodies. [0024]
