Lienwerkstoff closed, with the edge of the lid in simply folded around the possibly reinforced and horizontally outwardly protruding edge of the container is. Such a closure is sufficient at see the above Related requirements. It has been shown, however, that especially when handled improperly the side walls can easily be dented when transporting the container, e.g. because the frozen contents has shrunk. The fold of the container covered by the lid and the contents of the container are then released, at least Its components, which are later liquid when heated, can escape if it is not held exactly horizontally. Even with lateral impact loads, there is a risk of loosening the folded seam and thus a There is a gap between the container and the lid.

There is accordingly the task of establishing a connection between the container and the lid, if possible without any change of the common forms, which mean the general Requirements are sufficient, but is still so strong that the lid is deformed when the container is deformed can not easily solve.

The innovation solves the problem posed by a foil container as aluminum foil or a comparable suitable material with a lid, which with a flange encompasses the edge flange of the container _s whereby, according to the innovation, the essentially horizontally extending fold connection formed in this way, at least in its outer part the level of the cover is bent or angled downwards.

Other features of the innovation and details of the

advantages achieved by the same result from the The following description of the subject of the innovation based on the attached drawings.

Fig. 1 shows a film container and a

Lid. To close it, in

Fig * 2 shows the foil container according to the innovation.

The container shown has a rectangular bottom 1, which continues in walls 2 that run obliquely upwards. These containers made of aluminum foil are, for example, and preferably used to hold prepared foods that can be frozen in an already prepared state and stored in this way. In larger catering establishments, preferably in factory canteens and the like, these containers are heated in appropriate devices. The containers are then served immediately with their contents in a heated state. Since the perishable contents are stored frozen, an airtight seal is not necessary. One can here with the application of a lid 5 content, which at the edge fold & j5 ^it is placed with an edge fold 6 container.

Has the rebate connection changed, e.g. due to impact releasedj, - the contents of the container can escape. The solved one Folded connection has a particularly disruptive effect when it is heated, in particular because of evaporation and the escaping Food mix.

^v , well
This is where the renewal of the

Container. The through the edge fold 3 of the container and fold 6 of the cover 5 formed connection is bent down from the plane of the cover 5 or angled abge. The result is a formation of the fold, as shown in FIG. The fold connection is like this able to withstand any stresses that are considerably greater To oppose resistance. It dissolves even with extensive deformation of the side walls 2 of the Be container not. It takes part in the deformation without loosening.

In adaptation to the rolled-up area 4 of the edge fold 3 of the container, the lid can 5 with an embossed groove 7 be provided. However, this groove is not absolutely necessary.

The fold β of the cover 5 thus encompasses, as usual, the edge fold 3 of the container. During the folding process, in likewise in a conventional and known manner, the rolled-up area 4 is pressed together by the sealing tool. Through appropriate training of the closing tool but the rebate connection does not remain, as was previously the case, in the plane of the cover 5. » but becomes from this bent or angled. In the embodiment shown in Fig. 2, for example, the fold 3 of the run The container and the area 8 of the lid that covers it are still in a narrow zone in the plane of the lid 5 · Then if the fold connection has a crease 9, the fold 6 of the Cover 5 * which engages around the fold 3 and the outer area this fold 3 of the container with the now compressed linrollung 4 are angled downward with the edge area Io of the cover opposite the fold 6.

It is obvious that the edge fold of the container can easily pull out of the seam connection, when the sealing fold lies in the plane of the lid 5 and when the side walls 2 of the container are deformed will. It is equally evident that this is not now is more the case. Instead of the kink shown, the seam connection can also be made in any other arbitrary manner from the Be deflected downwards in the plane of the cover, e.g. by turning with any radius of curvature,

By deflecting at least part of the fold connection between container and lid, where they overlap, from the lid level down, there will be a better one and the stresses occurring in each case created connection between the container and the cover.
