Description

The invention relates to a packaging bag according to the preamble of claim 1.

For portionwise packaging of drinkable and / or spoonable products such. As fruit juices, water or soups are rigid or rigid, usually made by 3D thermoforming or injection molded plastic container with sealed lid and made of plastic laminate rigid bag known. Such packaging containers and bags are not ecologically harmless because of their increased to achieve the stability material requirements and also relatively expensive. In addition, the packaging is usually printed directly as an advertising medium and thus generally entail the risk of migration of undesirable substances in the medium in itself.

A packaging bag of the type mentioned is out CH-A-358 743 known.

The invention has for its object to provide a package for both drinkable and spoonable products such. As fruit juices, water or soups, as well as products with liquid and solid fractions or semi-solid products such. B. animal feed, which does not have the disadvantages of the prior art packaging described above or to a lesser extent.

For the inventive solution of the problem leads a packaging bag with the features of claim 1.

In a preferred embodiment of the inventive packaging bag, the bag material is a plastic film. To avoid migration of foreign substances into the bag interior, the packaging bag is unprinted.

The bag material and the outer packaging material are preferably mono-materials.

The overwrap material may be of any inexpensive monomaterial. A preferred outer packaging material is cardboard. The outer packaging can be printed as desired.

The outer circumference of the bag transversely to the bag longitudinal direction is expediently larger than the inner circumference of the tubular outer packaging, so that the bag is held in a non-positive manner in the outer packaging. Instead of a larger outer circumference may be provided on the bag when slipping over the edge of the outer packaging tearing dividing line.

The packaging bag has a peelable sealing seam parallel to and at a distance from the tear line. This can be avoided that prematurely reaches the top of the bag and when passing the bag head over the edge of the outer packaging reaches the outside of the opened package. An alternative solution is to coat the inside of the packaging bag with a release varnish.

The cross-sectional shape of the outer packaging is usually circular. For reasons of an attractive design, the circumferential line of the tubular outer packaging may also be polygonal, z. B. 4, 6 or 8-square.

The dimensions of the packaging bag and the outer packaging can be varied within wide limits. The relationship between the diameter or circumference of the bag and the outer packaging depends on the type of use and the contents. For a drinkable product, the height of the bag will be greater than its diameter. For a semi-solid product, such. As pet food, the base mass or the diameter of the packaging will be greater than the height. The packaging bag serves only to serve the contents and does not need to be cleaned after use.

The stability of the packaging bag results from the outer packaging, which may also be a cup or a cup. The packaging bag itself can be a stand-up bag without its own stability, a tubular bag or an extruded round bag. The bag material for the packaging bag according to the invention can have a smaller thickness in comparison to the stiff material required for a stand-up bag with its own stability and is consequently inexpensive. The outer packaging used as a cup or cup simultaneously protects the injury-prone bag from mechanical damage during transport.

The packaging bag is suitable in particular for the packaging of drinkable or spoonable filling products as well as of fillable products which can be stirred with liquid to drinkable or spoonable products. The packaging is also suitable for pet food. Depending on the type of contents this is still mixed with liquid, such as. As bag soups with hot water, or the product is already in liquid or spoonable form, z. B. yogurt.

In the case of water with and without carbonic acid, the packaging system serves to store the contents and at the same time as a drinking vessel. For pet foods and other semi-solid to solid products, serving is a significant advantage.

The heating of food such. B. soups can be done in the inventive packaging bag together with the outer packaging in the open state, optionally after mixing with cold water directly in a microwave oven.

Typically, individual packaging units each consist of a packaging bag arranged in an outer packaging. However, it is also conceivable that a packaging unit contains, for example, five packaging bags and only one outer packaging. Finally, for use with a standard cup, certain packaging bags may also constitute a packaging unit without tubular overwrap.

An in Fig. 1 illustrated packaging bag 10 in the form of a stand bag made of a flexible film material, such. As polyamide, has a sealed bottom 12, a front wall 14 and a rear wall 16. Two laterally arranged longitudinal sealing seams 18, 19 defining a longitudinal direction of the bag I connect the two bag walls 14, 16 rising from the base 12 and, together with a transverse sealing seam 20 connecting the longitudinal sealing seams 18, 19 at the bottom distal end, to the closed packaging bag 10.

The transverse sealing seam 20 at the bottom-distal end of the packaging bag 10 is part of an opening part 26 which can be separated from the bag. For opening the packaging bag 10, the opening part 26 is torn away along a tear line 24 arranged in the bag walls 14, 16 in parallel and at a short distance from the transverse seam seam 20. As a tear-open in the longitudinal sealing seams 18,19 tear scores 22, 23 are provided with ending at the tear line 24 tip.

Below tear line 24, at a distance parallel to tear line 24, there is a further seal seam 28 extending across the entire width of bag walls 14, 16, but which is peelable, i. along this peelable sealing seam 28, after the separation of the opening part 26, the bag walls 14, 16 can be separated from each other by hand without much effort.

Fig. 2 shows one of a dimensionally stable material such. As cardboard, manufactured tubular outer package 30, whose ends are parallel to each other and perpendicular to a tube axis z. The outer package 30 serves to receive the packaging bag 10 of Fig. 1 ,

A packaging unit consisting of the tubular outer packaging 30 with inserted in this packaging bag 10 is in Fig. 3 shown. The longitudinal direction I of the packaging bag 10 lies in the tube axis z of the outer packaging 30. The one end of the tubular outer packaging 30 serves as a base for the packaging unit, so that the packaging bag 10 itself does not have to be made stable. The packaging bag 10 can therefore also be a simple tubular bag with a longitudinal seam and two transverse seams.

The tubular outer package 30 is a hollow cylinder in the example shown, but instead of a circular cross-sectional shape, another design is possible. Thus, the circumferential line of the tubular outer packaging may for example have the shape of a regular polygon.

In an outer package 30 in the form of a hollow cylinder whose inner diameter is smaller than the outer diameter of the formed into a bag with a circular cross-section packaging bag 10th be partially attached to the inside of the outer package 30, for example via point splices 32 partially. The distance a of the peelable sealing seam 28 from the tear-open line 24 is selected so that the peelable sealing seam 28 protrudes slightly from the outer packaging 30 when the packaging bag 10 is inserted in the outer packaging 30.

After the tearing off of the opening part 26, the peelable sealing seam 28 is separated by pulling the free ends of the bag walls 14, 16 apart and the bag is thereby completely opened ( Figure 4 ). Subsequently, the protruding from the outer packaging 30 part of the opened packaging bag 10 is placed over the outer packaging 30. ( Fig. 5 ). In this process, the inside of the bag walls 14, 16 swept to the outside, creating a hygienic opening area.

The everting process is facilitated by the outer circumference of the packaging bag 10 which is larger than the inner circumference of the outer packaging 10. Alternatively or additionally, the longitudinal sealing seams 18, 19 of the part of the packaging bag 10 protruding from the outer packaging 30 can be made peelable. In this case, when everting the bag walls 14, 16 takes place at the same time a partial or complete separation of the longitudinal sealing seams in this area.

The peelable sealing seam 28 prevents the ingress of filling material into the area between the peelable sealing seam 28 and the tear-open line 24 in the unopened packaging bag 10, so that even after the bag has been opened, the part of the bag protruding out of the outer packaging 30 and turned outwards does not already adhere to contents.

When slipping over the protruding from the outer packaging 30 bag part on the opening edge of the outer package 30, a cup with hygienic opening area, which can be done without hesitation directly to the mouth.
