DESCRIPTION:
BRIEF SUMMARY
This invention relates to a resealable pack. It is particularly intended for use in the packaging of wet wipes, but it is to be understood that the invention is also applicable to the packaging of other articles.
As is well known, wet wipes are articles in the form of small sheets which are impregnated with a skin- cleansing liquid and which are intended to be disposed of after a single use. Wet wipes are sometimes packaged individually, in which case the packaging is thrown away after it has been opened and the wet wipe removed therefrom. However it is also known to produce a pack containing a plurality of wet wipes. In that case, the pack must be provided with a resealable opening, since the skin-cleansing liquid with which the wipes are impregnated evaporates readily, and the wipes will therefore dry out unless the pack can be properly resealed after each wipe is removed.
Where a large number of wet wipes, say 40 to 200, is to be held in a pack, a rigid tub of cylindrical cross-section is conventionally used for this purpose. However, this is not always convenient from the point of view of the user, particularly where the pack is to be carried around in, for example, a handbag, and under such circumstances it would be preferable for the pack to be relatively flat and, preferably, at least slightly flexible. It is an object of the present invention to provide a pack which is a practical alternative to the rigid tubs conventionally used.
According to the present invention there is provided a pack having a body portion formed substantially of flexible sheet material and defining an article- receiving cavity, the body portion having a face in which is defined a dispensing opening; a resealable sealing member secured to the body portion and, in a closing position, covering the said opening and being in sealing contact with the body portion around the periphery of the said opening; and a plurality of sheet-form articles disposed within said cavity in the form of a flattenable roll, with one end of the roll being capable of extending through the said opening.
The body portion preferably has a thickness which is less than its length and is less than its width, and it is preferably in the general shape of a parallelepiped. The body portion is preferably made of a flexible, sheet plastics material, and the sealing member is likewise preferably made of a flexible, sheet plastics material.
An embodiment of the invention is shown diagrammatically in the accompanying drawings in which:
FIG. 1 is a plan view showing the side of the pack in which the dispensing opening is provided, the closing member being in its closed position;
FIG. 2 is a perspective view of the pack;
FIG. 3 is a plan view of the pack of FIG. 2, again in its closed position;
FIG. 4 is an edge view of the pack of FIG. 2, again in its closed position;
FIG. 5 is a view corresponding to FIG. 2, but with the closing member shown partially opened;
FIG. 6 is a view similar to FIG. 3, but with the closing member opened to a greater extent than in FIG. 5;
FIG. 7 is a perspective view, with the closing member in approximately the same position as in FIG. 6, and with the end of a wet wipe protruding from the dispensing opening;
FIG. 8 shows, by way of example, six possible shapes for the dispensing opening;
FIG. 9 is a cross-section through the pack; and
FIGS. 10a and 10b show diagrammatically a method of producing the pack according to the invention.
The illustrated pack is intended to hold from about 40 to about 200 wet wipes each approximately 230.times.160 mm, and each impregnated with a skin-cleansing liquid. The pack comprises a body portion 1 which is formed of a flexible sheet plastics material, for example a polyethylene film, a polypropylene film or a laminate consisting of, for example, polyethylene and polypropylene layers, optionally with a layer of paper between them. In the illustrated embodiment, the body portion is formed wholly of flexible sheet plastics material. Alternatively, however, the base of the body portion, that which is at the lowe
