Description

The present invention relates to a packaging container according to the preamble of claim 1. Such a packaging container is in FR 2 928 353 disclosed.

Such packaging containers are known in particular for two-component adhesives and exemplified in the DE 296 13 563 U1 described. The problem, however, is that after cutting the outer container with the removal of the mixed component often associated with this inner container is necessarily removed with.

It is an object of the present invention to improve a generic container with respect to the mentioned problems.

The object is achieved by an article according to claim 1. Advantageous embodiment of the invention can be found in the dependent claims and the following description.

The outer container has means for forming a removal opening or already a closed removal opening, the dimensioning of which can be predetermined and in particular tuned to the inner bag. The area provided for forming the removal opening is, for example, a corner or other shaped area of the outer container that can be used in the manner of a spout. Thus, during the removal of the mixed component, in particular of the mixed beverage, a removal of the inner container, preferably an inner bag consisting of film material, is prevented as far as possible or completely. During normal use, ie, when the mixture is removed through the removal opening, the inner bag is thus undetachable. Such a packaging container is particularly advantageous for the use of modern mixed drinks. Here, in the interior of the inner container a flavor-giving, also alcoholic component may be located, while the interior of the outer container located outside of the outer container of a ground substance, which forms the basis of the mixed beverage is filled. By means of such a packaging container, in particular made of film material can be produced in a variety of low-cost, easy to transport and easy to dispose of, preferably alcoholic mixed drinks.

The inner bag preferably has a larger dimension in a projection onto a surface formed by the free cross section of the removal opening, at least in a longitudinal or transverse direction. In particular, in an inner bag variant designed by means of a peripheral sealing seam, the inner bag, after mixing the two components, can have a shape caused by the sealing seam, leaving it elongated in the manner of a flat cushion with dimensions which do not pass through the removal opening.

Alternatively or additionally, the outer container, in particular in the region of the removal opening or towards this also means for reducing the free cross-section, in particular the removal opening, have. Here are introduced into the outer container grating, foil flanges or the like. conceivable. In particular, such a means can also be a weld point for connecting opposite sides. The passageways are then for the pouring mixed component then still sufficiently large, while the dimensions of the empty inner bag are too large to pass through the reduction of the free cross section through the discharge opening or through it. The introduction of welds is possible during the filling or sealing of the outer container in a simple manner.

The removal opening is predetermined by a material weakening of at least one side of the outer container or a tear thread connected thereto. In this case, in particular laser-introduced perforations of a sheet material forming the outside can be used. Alternatively, the removal opening can also be formed by a welded-in pouring spout which is introduced into the outer container and welded there, in which, in particular, pouring is unproblematic owing to the then fixed side walls of the spout and, unlike often with film material.

The removal of a packaging container constructed of film is further improved if, in the region of the removal opening, at least one side of the packaging container is provided with a stiffening of a removal region, preferably produced by a profiling. The removal area here is the area of the packaging container leading to the removal opening. This is preferably one or more profiles introduced, in particular, by embossing in the sides of a packaging container, which preferably point towards the removal opening in the direction of their main longitudinal extent. So even when emptying flat compressible, Made of film packaging containers removal channels are created, which can ensure a simple pouring effectively.

Alternatively or additionally, it can also be material thickening or, for example, tubes formed in the film or arranged on the inside thereof to form stabilizing or feed channels.

A purposeful design of a packaging container, which can simultaneously effectively prevent the removal of an inner bag, is given when the outer container has a bottle-shaped contour and the removal opening is arranged in the region of the bottle neck. In particular, introduced profiles are particularly effective in such a bottleneck. At the same time can be ensured by the shape of the sealing edge and the contour of the packaging container, a rising of the bottle neck during a pouring a mixed component. The area of the bottleneck before the removal opening is then preferably the region described above with means for reducing the cross-section and the free passage area.

While the inner container is preferably arranged freely movable in the outer container and thus the complete removal can be prevented, it is advantageous in variants of the packaging container according to the invention, in which the inner container is comparatively large and made of very flexible film, set this inner container complementary within the outer container respectively. to keep. This can be done, for example, by integrating an edge region of the inner container into a sealed seam of the outer container.

Manufacture, filling and sealing of the packaging container are simplified if the outer and / or inner container is / are formed as a Form-Fill-and-Seal (= FFS) bag.

For the use of particular liquid components, in particular foods, such as mixed drinks, it has proven to be advantageous to provide the sealed seam of the inner container with a Siegeinahtkraft between 1 and 10 N / 15 mm, preferably between 2 and 7 N / 15mm. As a result, a transport of a packaging container according to the invention is effectively ensured, for example, as a substitute for known packaging containers in the form of cans.

For the same reason, the sealing seam of the outer container should have a sealing seam force of more than 15 N / 15 mm.

The identification of the contents of a packaging container and a check as to what extent the two components are mixed together will then be facilitated, at least one side of the outer container being partially transparent. As a result, for example, with a transparent window arranged on one side and simultaneously circulating edge-side printing of the film, visually appealing packaging containers can be created which, for example, have an at least approximately bottle-shaped contour, at the same time but also stand out in an impressive way from the usual bottle shapes. As a bottle-shaped contour is understood here as having a wider cylinder neck and a narrower neck. Preferably, a packaging container is at the same time designed as a stand-up pouch which can have lateral side folds to increase the fillable volume, in particular when the front side is unchanged, and to reduce the required volume after removal of the mixed beverage. Particularly advantageous is a design of the packaging container according to the invention as a stand-up bag by the associated possibility of creating a stationary and thus better adaptable to a bottle contour container. Such a container can also be turned off between periods of consumption and maintain its bottle shape.

A transparent side of the outer container is also to be understood as a tinted side, which transmits only light of a specific wavelength.

In a further embodiment of the invention, at least one side of the inner container is at least partially transparent, which allows attractive visual effects of the components before mixing, on the other hand, represents an indication of the content of the inner container or bag.

In an alternative, not part of the invention, for forming the outer container as a stand-up pouch, this can also be designed as a tube. Thus, the material for the outer container may also be injection molded plastic and not just blown or cast film.

As materials which come into question for the outer and / or inner container, single or multilayer film materials, in particular due to the associated production costs are advantageous. Compared to conventional glass packaging, significant cost savings can be achieved. At the same time, due to the large number of possible sealing edges, it is possible to produce a large number of different packaging containers, all of which are bottle-shaped at least in the contour.

Particularly advantageous as a material for the films are polyolefin films (PE and / or PP), polyester films with / without barrier coating of, for example, aluminum; Alumina or silica. In particular, silicon oxide can be used as barrier vapor for the transparent sidewalls. Also aluminum foil or polyamide film are conceivable. As multilayer films, coextrusion films or laminating films can be used.

Any imprints in the spout area can be designed differently. In particular, a semi-tubular embossment from the inside to the outside on both sides is conceivable.

In addition to the use of the packaging container for cocktails according to the invention, there are a multiplicity of other fields of application of products which are to be stored separately and are mixable before use, in particular cleaning articles, Fertilizer or colors. The materials used in the packaging container must be adapted accordingly to these ingredients.
