Definitions
- the invention relates to a container for gas-tight packaging according to the preamble of patent claim 1.
- gas-tight packaging for example of carbonated beverages
- glass containers or in deep-drawn, cylindrical sheet metal containers have the advantage that they can also be exposed to the temperatures of 130 to 140 ° C required for sterilizing the contents of the container, but they require a relatively large transport volume for their transport from the manufacturer to the bottler, since they cannot be stacked.
- plastic containers e.g. made of polyester, which can be exposed to elevated temperatures even without deformation, have shown that their gas tightness is not sufficient to maintain an elevated gas pressure over a longer period of time, as is required for the filling of, for example, carbonated drinks.
- Used gas-tight containers of known type also put a burden on waste disposal systems.
- the invention has for its object to find a container of the type mentioned, which consists essentially of residue-free combustible material and with sufficient mechanical resistance, in particular against permanent deformation, e.g. due to transport loads, has sufficient gas tightness and which also enables thermal sterilization of its contents. Furthermore, the container should be stackable before it is filled.
- the inner container preferably consists of a plastic-coated aluminum foil, the outer plastic layer being weldable to the material of the outer container if the latter is also made of plastic or is connected to it by adhesive if it is made of another material, e.g. Cardboard consists.
- the thickness of the film mentioned is less than 0.15 mm and the aluminum layer itself is preferably less than 0.02 mm.
- the inner container made from a film cut ensures the tightness of the container and the light protection of the container contents.
- the plastic coating of the aluminum foil contributes to this tightness and also protects the aluminum layer from corrosion.
- the overlap seams of the inner container are preferably designed in a manner known per se so that the same coatings of the film are welded to one another. This results from the fact that the inner layer is first folded outwards before the overlap edge is placed over it for welding. This results in a triple layer thickness along the overlap seams. When the container is subjected to internal pressure, these layers are pressed against each other at the seam, so that the reliability of the seal is increased there.
- the inner container having the aluminum layer is particularly thin-walled means that permanent deformations under external local pressure application and elastic deformation of the outer container are not possible.
- the outer container ensures the stability of the container and protects the inner container from damage that could cause a leak.
- the blanks for the inner container and thus the inner container can preferably be printed if the injection-molded or deep-drawn outer container is made of transparent plastic, for example polypropylene.
- the outer container itself can have the printing and, for example, be made of cardboard, as is known per se from CH-PS 647 453.
- the closure of the container after it has been filled can, depending on the intended use, e.g. as a drinking container, through a relatively stiff, gas-tight lid, which is connected to the container flange, e.g. by flanging or welding.
- the container lid is made of sheet metal with a zipper, similar to tin cans, or, like the rest of the container part, it is made of multiple layers, with a thin film part ensuring tightness and a rigid cover part connected to it.
- a container closure made of sheet metal is known, for example, from US Pat. No. 3,190,485.
- the container 1 shown has a relatively rigid outer container 2, which determines the shape stability of the container and protects the very thin-walled and correspondingly flexible inner container 3 lying against it from damage.
- the outer container 2 can be injection molded from plastic, e.g. Polypropylene, deep-drawing or winding from cardboard material must be made separately, so that the inner container, which is in each case made separately from film blanks, is subsequently inserted into it and connected to it by gluing or welding at least along the edge flanges 4, 4 '.
- the prefabricated inner container 3 is preferably placed in an injection mold and the outer container 2 is directly molded onto the inner container 3 by injection molding, so that it is welded to its thin plastic layer.
- the inner container 3 thus forms a container lining.
- the wall thickness of the outer container 2 which e.g. Is 0.5 mm or more, is essentially determined by the strength requirements for the container 1.
- the gas permeability is immaterial, so that other aspects, such as environmental friendliness and / or cost-effectiveness, can be preferred.
- the inner container consists of a thin film, preferably less than 0.02 mm thick, whose choice of material is primarily determined by the requirement for very high gas tightness. Accordingly, a relatively high quality material, such as plastic-coated aluminum foil to choose, but this is only required in very small quantities.
- the minimum thickness is essentially determined by the processability into an inner container 3, so that this is produced from blanks for its jacket part 8 and its bottom part 7 by the connecting seams for producing the spatial structure being formed by gas-tight overlap seams 5, 5 ', 13.
- the outside of the film of the inner container 3 is thinly coated with a material which is compatible with the material of the outer container, e.g. Polypropylene, slightly welded.
- the other, inner side of the film is coated with conventional thermal lacquer in order to be able to easily produce the seam connections 5, 5 ', 13 by heat sealing.
- FIG. 3 and 4 show two examples of an overlapping connection along the casing seam 5 or 5 'running in the direction of a casing line, such that the inner layers of the film lie one on top of the other and are welded together along the seam 5,5'.
- FIGS. 5 and 6 show the initial simple overlap for two different arrangements of an overlapping connecting seam 13 before it is folded against the jacket part 8 of the inner container 3 in the example according to FIG. 5 and against the bottom part 7 of the inner container 3 in the example according to FIG. 6 to be welded in this end position.
- a film edge 11 ′, 11 ′′ which continues in the end position over the folded-over film part 10 ′.
- the thermal conductivity of the aluminum layer has a surprisingly advantageous effect on the thermal shrinkage after the finished container 1 has been molded from an injection mold, if the inner container 3 is in it by the Outer container 2 is encapsulated by the shrinkage is about 50 percent less than without using an aluminum foil.
