Abstract
ABSTRACT OF THE DISCLOSURE
The beverage container consists of a middle part and two bottom or end cap parts which close its front sides;
the latter are welded to the film web which forms the middle part. Due to the fact that the middle part is closed on both ends by means of welded-in end cap parts, the container is developed as a pressure tank for receiving carbon-dioxide containing beverages.

Description
12451~32 The invention deals with a beverage holder, made out of a flexible multi-layer film, consisting of an internal layer of weldable plastic, impermeable to liquids and of an intermediate layer, tight enough to prevent the escaping of flavorings, which is provided on its one side with a - by means of a welded-in bottom or end cap part or portion - self-contained middle part, it especially deals with a beverage bag.
Beverage holders of this kind, developed as bags, are known and are for instance described in the DE-OS 22 34 933 and in the DE-PS 12 81 140.
The beverage bag according to the DE-OS 22 34 933 has an internal layer, impermeable to liquids, made out of thermoplastic, and thus weldable plastic as well as an intermediate layer, tight enough to prevent the escaping of flavourings, and consists of two film webs, connected on their longitudinal sides by longitudinal weld seams, and of a bottom part, folded V-shaped inwards within the area of the one narrow side of the film webs, developed as a put-in bottom piece which is welded to each film web by means of a U-shaped weld seam.
At the beverage bag according to DE-PS 12 81 140 the bag side-walls and the bottom are made in one piece of continuous film web. Within the area of the one narrow side of the bag, the bottom is folded V-shaped inwards, that is between those parts cf the film web which form the side-walls, and on their long tudinal sides the film webs are connected by means of longitudinal weld seams, which grasp at one time four film web layers within the area of the folded bottom part.
Beverage bags of this kind have already been used in large quantities as portion packings for so-called still beverages, as for example fruit juice beverages. They have proved well so far, though particular measurements are necessary in order to guarantee a certain tightness and also to reach stability.

Compared to those a beverage holder according to thls invention, made out of a flexible multi-layer film~
is developed according to claim 1 as pressure tank for the taking-in of carbon-dioxide containing beverages, by the fact that the middle part of this holder is self-contained by means of the welded-in bottom or end cap portions at both ends.
Beverage holders of the state of engineering as mentioned above were sealed, after having been filled, by a transverse weld seam on the other side of the welded-in bottom part. Especially these transverse weld seams but also the longitudinal weld seams, which connect the side walls of the bag, could not withstand permanently the in-ternal pressure admission, caused by carbon-dioxide con-taining beverages. Thus the invention has solved the task to improve the beverage holders, made out of flexible multi-layer film, which up to now could only be used as packaging for materials without pressure, in such a way, that they can be filled with carbon-dioxide containing beverages, which hitherto required far more expensive packagings as bottles or cans. Thus this invention has adjusted the known beverage holders to a till now not possible use and so has largely increased their usefulness.
A design of the invention provides, that the end cap portions~ which close the middle part on its both ends, are identical with each other or are at least homogeneous. A beverage holder according to this design is at least nearly symmetrical with regard to its longitu-dinal axis and to one medium axis, extending rectangularly to the longitudinal axis.
At another design the middle part consists of at least one film web, which is tube-shaped and which is welded in a longitudinal weld seam alor~g the edges extending in longitudinal direction of the holder, thus in principle vertically to the end cap portioris.
B
~LZ~L51~3~:
It is recommended to make the longitudinal weld seam of the middle part and/or the weld seam, which connect the end cap portions with the middle part, as scarf joints, which are especially suitable for withstanding an internal pressure admission, while other weld seams, where edge strips of the film materlal, which extend outwards from the inner holder, are welded together tend to come loose gradually due to the internal pressure admission, until finally the beverage holders with such weld seams will burst due to the internal pressure.
Consequently according to a further feature, the end cap portions are provided all around with edge flanges in order to weld them to the end edges of the film web forming the middle part and they are suitably placed in with their flanges facing inwards into the middle part. Another advantageous design of this invention is, that the end cap portions are formed as dished parts on that side which is turned away from the middle part.
It is also of advantage if one of the end cap portions welded to the middle part at a distance from the adjacent end of the middle part, in such a manner, that the outward curvature of the end cap portion, which may be caused by internal pressure caused by the stored liquid, does not protrude beyond the near end of the middle part. In such a design, the end of the beverage holder at which the bottom part is welded at a distance from the front side of the middle part, can form a kind of pedestal for the container.
Finally, it is also of advantage, if the middle part is developed rotary-symmetrically with regard to its long-itudinal axis and especially if it is developed cylindrically and if consequently the bottom parts are developed hemis-pherically with bordering weld-in flanges. Irrespective of the lack of stiffness of form of the film material, out of which the beverage containers are produced, such beverage .~
~5~9~
conatiners are superior by their extraordinarily great resistance against internal pressure.
With the help of the attached drawing several designs of the invention will be described. The schematic represent-ations show FigO 1 a perspective view of a beverage holder or container, develpped as a pressurized con-tainer for receiving carbon-dioxide cont-taining beverages, having a cylindric middle part made of a film web and end cap portions welded to both ends of the middle part by means of scarf joints extending about the periphery;
Fig. 2 a cross section along the line II-II of Fig. 1;
Fig. 3 a further design of a beverage container with a cylindric middle part made out of a film web and bottom parts, welded-in on the front parts, the bottom parts are developed as dished parts on those sides, which are turned away from the middle part;
in a lateral side view;
Fig. 4 a sectional view according to the inter-secting line IV-IV of Fig. 3 of the holder end after having been filled and closed by means of welding-in of the upper bottom part.
The beverage holder 10, developed as pressure tank, consists according to Figures 1 and 2, of a cyllndrical middle part 11 and of bottom parts or end cap portions 13,13', which are welded-in into the latter on its both ends. The middle part 11 consists of a film web, formed into a cylinder or tubular jacket, whose edges overlap the bordering longitudinal edges and which are welded by a longitudinal weld seam 120 The end cap portions 13,13' are formed as a kind of turned-up caps and are each pro-vided with a continuous, generally cylindric peripheral flanges 15,15', which fits the cylinder shape of the B
12a~Sl9~
middle part 11. The end cap portions 13,13' are inserted in into the ends of the cylindrical middle part, such that their flanges face inwards to the cylindrical middle part, and they are welded with the front end edges of the middle part by means of continuous peripheral weld seams.
The film web, out of which the middle part 11 is formed, is a laminated film material, which consists of an internal layer, impermeable to liquids, made out of a weldable plastic, neutral as regards taste, for example Polyethylene, as well as an intermediate layer, made out of a metal foil, which, as is known, reliably prevents the escaping of flavourings. The end cap portions 13,13' con-sist of a similar multi-layer film, which also has a weldable layer on its outside.
The beverage bag 10, which is to be filled with carbon-dioxide containing beverages, is conveyed to a fil-ling station, already provided with a welded-in end cap portion 13 on one end of the middle part 11, is there filled with a carbon-dioxide containing beverage and then closed by welding-in the second end cap portion 13' on the other end of the middle part. With the closing of both sides of the middle part 11 by means of one end cap portion at each end 13,13', the be-~erage holder 10 is developed as a pressure tank, which is capable to withstand the arising internal pressure, under normal circumstances.
In the embodiment according to Figs. 3 and 4, the corresponding parts to Figs. 1 and 2 are designated with reference numerals increased by 10.
The beverage holder 20 differs from the design according to Figs. 1 and 2 by the fact, that the end cap portions 23,23', closing the middle part 21 at its ends, are formed as shell-parts, dished outwards and are provided with an edge flange 25, adjusted to the cylindrical middle part and facing inwards, into the container. They are further welded to the middle part by means of weld seams C

24,24', developed as scarf joints. The middle part 21 consists of a cylindrical film web, whose longitudinal edges overlap and are welded together by means of a long-itudinal weld seam 220 Also in comparison to the design according to FigsO
1 and 2 the end cap portion 23 is welded by means of a circular weld seam 24,24' and in a distance from the front edge of the cylindrical middle part 21, into the middle part 21 in such a way, that the convex curvature of the bottom part 23, being under pressure, does not protrude beyond the near end of the cylindrical middle part, bordering the circular weld seam 24. The part 26, standing out from the circular weld seam 24, connecting the end cap portion 23 with the middle part 21 thus forms a kind of pedestal for the containerO
A characteristic for the described beverage holders 10,20 according to Figs. 1 to ~ is their design as pressure tank made out of a flexible multi-layer material with a low natural stiffness; a further characteristic is in its function as a container for carbon-dioxide containing beverages. With regard to the fact, that all weld seams are developed as scarf joints, where, due to the internal pressure caused by the carbon-dioxide containing beverage-filling, only shear-strains will occur, the above described designs of the inventive container are especially resistant against the effects of internal pressureO

Beverage holders of this kind, developed as bags, are known and are for instance described in the DE-OS 22 34 933 and in the DE-PS 12 81 140.
The beverage bag according to the DE-OS 22 34 933 has an internal layer, impermeable to liquids, made out of thermoplastic, and thus weldable plastic as well as an intermediate layer, tight enough to prevent the escaping of flavourings, and consists of two film webs, connected on their longitudinal sides by longitudinal weld seams, and of a bottom part, folded V-shaped inwards within the area of the one narrow side of the film webs, developed as a put-in bottom piece which is welded to each film web by means of a U-shaped weld seam.
At the beverage bag according to DE-PS 12 81 140 the bag side-walls and the bottom are made in one piece of continuous film web. Within the area of the one narrow side of the bag, the bottom is folded V-shaped inwards, that is between those parts cf the film web which form the side-walls, and on their long tudinal sides the film webs are connected by means of longitudinal weld seams, which grasp at one time four film web layers within the area of the folded bottom part.
Beverage bags of this kind have already been used in large quantities as portion packings for so-called still beverages, as for example fruit juice beverages. They have proved well so far, though particular measurements are necessary in order to guarantee a certain tightness and also to reach stability.
