Abstract

ABSTRACT

A beverage container is disclosed which has walls (11) having a liquid-tight inside layer (12) of thermoplastic synthetic material end e further layer (13) of a gas-tight material. A perforation penetrates the outer layer or layers to the inside layer, and forms an opening for inserting a drinking strew. The closure (17) of the opening is made of e multilayer closure strip covering the opening and with an inside layer (12') of thermoplastic synthetic material and a further layer (13') of a gas-tight material. This thermoplastic inside layer of the closure strip is fused to the portion of the inside layer of the container wall which is exposed in the opening area. The closure strip may be of the same materials as the walls of the container.

Description

'1~16130 The present invention relates to a beverage container of multilayer composite material having a liquid-tight inside layer of thermoplastic synthetic material, with a perforation extend-ing to the inside layer to form an cpening for inserting a drinking straw. In particular, the ir.ver.tion relates to a beverage container made of flexible foil material.
There are already known in the art beverage containers which are made of at least one exterior carrier layer and a liquid-tight inside layer and provided with an insertion open-10 ing for a drinking straw closed by means of a tear-off adhesive strip. The zdhesive strip is pasted to the exterior layer of the wall material surrounding the insertion opening and has a tab for tearing it off.
With aromatic beverages, these closures have proven 15 permeable for the passage of aromatic matter so that quality deterioration was found between bottling and consumption of such beverages. Also, such closures do not withstand the con-ditions cccurring during transport and the storage of such beverage containers.
There is already known a beverage container of multilayer composite material where a cover strip is inserted in a with-drawal opening penetrating the container wall and a thermoplas-tic inside layer of the cover strip is fused to the cutout edges of a liquid-tight thermoplastic inside layer of the container 25 wall. This closure dces not provide sufficient tightness - against the penetration of aromatic matter, because only the edges of the inside layer of the cc,ntainer walls are fused to the thermoplastic inside layer of the cover strip. Furthermore, this closure provides no security against leaks unless such con-30 tainers are of stable shape and no pressure can be exerted from the inside to the outside on the walls during transport and storage.
There are also known beverage containers consisting of multilayer composite materials having perforation of the outer 35 layers of the composite material penetrating to ~he liquid-tight inside layer, so that after piercing the inside layer `` 11161~0 there develops an cpening through which a drinking straw can be inserted in the container~ Even thoug~ the liquid-tight inside layer is thin, it has ~een found difficult to pierce this layer with a straw. The consumers of the beverages con-tained in such beverage containers frequently have no meansbesides the drinking straws for piercing the inside layer ex-posed in the vicinity of the perforation and an additional difficulty is encountered in the resilience of the walls.
According to the present invention there is provided a beverage container comprising walls of at least an inner layer of liquid-tight thermoplastic material and a further layer of a gas-tight material, an opening extending through the further layer and up to the inner layer, and a closure member to cover the opening and of material having at least an inner layer of liquid-tight thermoplastic material and a further layer of a gas-tight material, the inner layer of the closure member being joined to the portion of the inner layer of the cc,ntaine~ walls exposed by the opening.
A safe sealing of the insertion opening is achieved which ensures particularly simple handling since the closure strip is solidly connected to the beverage container material only in the perforated area while the portions overlapping the perforation contact the container walls only from the outside.
Thus, when tearing off the closure strip, which is done by pulling a tab or the portion of the closure strip overlapping the perforation, that portion of the inside layer of the con-tainer walls is torn out along the peripheral contour of the perforation. This produces an opening in the container wall through which the drinking straw can be easily inserted.
An embodiment of the present invention will now be more particularly described by way of example with reference to the accompanying drawings, in which:
Fig. 1 shows a perspective view of a beverage container which has an insertion opening for a drinking straw and closed by a closure strip with tear-off tab;
Fig. 2 shows the upper end of the container in a section ~ . ~
-~1~6~30 taken along line II~II of Fig. 1, Fig. 3 shows an enlarged sectional view of ringed area IV of Fig. 2 before fusing on a closure strip; and Fig. 4 shows an enlarged view of ringed area IV of Fig.
2 with a fused-on closure strip.
Referring now to the drawings, the container shown in Fig. 1 is a beverage container 10 whose walls 11 are made of flexible foil laminate material consisting of a liquid-tight thermoplastic inside layer 12, a gas-tight intermediate layer 13 and an exterior cover layer 14. Po]yethylene may be used as the thermoplastic in~ide layer 12 while use of a thin alum-inium foil as the intermediate layer 13 forms an excellent gas lock and hence prevents penetration of aromatic matter. The exterior layer 14 is nct fusible and may be cellophane or a suitable varnish coat.
A filling opening is located at the top, and is closed after filling with a beverage by means of a fused seam 15.
Near the opening one of the container walls 11 has an inser-tion opening 18 for a drinking straw and closed by means of a tear-off closure strip 17 having a tab 16. Fig. 4 shows details of the closure strip 17 which is made of the same foil laminate material as the container walls. Accordingly, it has a thermoplastic inside layer 12' of polyethylene, a vapor-tight intermediate layer 13' of thin aluminium foil and a non-fusible cover layer 14' of cellophane or cover varnish.
Fig. 3 shows the laminate material from which the con-tainers are made, which is provided with a perforation 20 penetrating only the outer layers 13, 14. The holes are covered on the inside by the undamaged thermoplastic layer 12.
Before fusing the containers at seam 15, closure strip 17 is placed on perforations 20, with the fusible inside layer 12' located on the side adjacent to the perforation and fused with the use of pressure and temperature to the thermoplastic in-side layer 12 of the wall material which is exposed in the perforation zone.
This provides a beverage container with a liquid-tight and aroma-tight opening f~r insertion of a drinking straw and * trademark ~1~6~30 this opening is distinguished by a closure which is secure against large l~quid pressures and yet can be removed in a simple manner. To expose the insertion opening, it is merely necessary to tear off the closure strip 17. The portion of the inside layer 12 fused to the inside layer 12' of the clo-sure strip remains stuck to the closure strip and is torn, as indicated at 22 of Fig. 4, along a contour determined by the perforation 20.
