Description:

The innovation is based on a container with the features specified in the preamble of claim 1. Such a container is known from DE-GM 76 01 192 and DE-GM 78 30 145. 5

The known containers are those for packing, in particular, deep-frozen cakes. The containers are made of food-safe, deep-drawn PVC film and are provided with a vertically running corrugation. In the container known from DE-GM 78 30 145, the container base is double-walled and contains a ring made of rigid polystyrene foam inserted from below, which gives the lower part dimensional stability and at the same time has a heat-insulating effect. On the ring made of rigid polystyrene foam, the lid is supported by a horizontal collar surface near its lower one Edge off.

It has now been shown that the packaging containers when stacking and during rough transport with contents

Bumps and knocks are exposed, which despite the corrugation denting of the cover and too damage to the packaged goods.

The innovation is based on the task of making containers of the type mentioned above in a simple and inexpensive, way of bracing suitable for mass production .;

This task is solved by using a container

the features indicated in claim 1. Advantageous developments of this new design are the subject of the subclaims. The grooves for receiving the Sfcütz-

] 'bodies can through the already necessary deep

drawing process are molded into the container, so do not require a separate operation. The supporting body, which are adapted in shape to the grooves receiving them are to be manufactured separately, but theirs is Design is simple in terms of production technology and is therefore cheap to produce.

The support bodies are only required at individual points on the container. For a round cake box e.g.

it is sufficient to have three to six, preferably four, points regularly distributed around the circumference of the box Provide grooves with such support bodies. The view through the lid of the wrapped cake remains open this way freely.

In order to be able to absorb vertical loads ur, d, the lid preferably rests with a horizontal collar surface on a horizontal collar surface and / or on the preferably flattened upper edge of the container base and the grooves end at this edge or at these collar surfaces and are open at their qeqenüberlieqenden ends for inserting the support body. If grooves with support bodies are provided both in the lower part of the container and in the lid, the lid should be placed in such a way that the support bodies in the lid are aligned with those in the lower part of the container and are supported on the latter. If f - known as in cake boxes per se - a heat-insulating and form \ stabilierender hard foam ring is inserted into the container lower part, then in the container base course dispensable grooves with support bodies to further stiffen

and the cover is then expediently supported with a collar surface on the ring of the lower part, which at the same time delimits and closes the grooves at the lower end.

In order to be able to stack the generic containers in a space-saving manner until they are used, it is known to make them slightly conical; you can then put them together. In order to be able to do this with the newly designed containers, the grooves and with them the support bodies are also expediently slightly conical in shape. Space-saving stacking is of course only possible as long as the support bodies are not pushed into the grooves. The %

Support bodies are supplied loose and only when in- " Use of the container inserted into the wall. One advantage of the innovation is that the container can also be used without the support body, provided that the container is less stable from case to case can be accepted. Another advantage is that the containers - each according to content or purpose - optically classify by inserting differently colored supports

From the point of view of the loose delivery of the support body, it is of course advantageous if these all have the same shape.

The support body can in principle be sufficient from any consist of rigid material, e.g. from Hola “However, a moderately compressible material is preferred such as rigid polystyrene foam used, which not only takes on an adequate support function, but can also cause a certain dampening and cushioning of bumps and blows. To this end It is also preferred - to make the support bodies somewhat longer than the grooves, so that they are a little longer from these protrude and act as a buffer when the filled containers are stacked.

A preferred embodiment of the newly designed container is shown schematically in the accompanying drawings.

in the area of a support body.

The container shown is intended to hold piner frozen cake. It consists of a lower part 1 and a cover 2. The lower part has in its bottom an at least 3 fist-sized Öffnuna 4 to _v. so that the cake lying on a paper plate 20 can be inserted or lifted out particularly carefully by reaching through the opening 4 from below with one hand.

The lower part 1 consists of thin, deep-drawn polyvinyl chloride film and has a circumferential, downwardly open groove 14, which is parallel or slightly downward from each other removing side walls 15 and 16 and by the flattened upper edge 6 of the lower part 1 is limited.

Only for the sake of greater clarity of the drawing is the film of the lower part 1 relative in FIG. 1 thick and the angle between the side walls 15 and 16 drawn relatively large. Located in the groove 14 a ring 16 made of rigid polystyrene foam formed from two half-rings. This extends from the floor The ring 18 extending up to the upper edge 6 is loosely inserted into the groove 14 and adheres through it Friction. A further fastening of the ring 18 is superfluous.

The lower part 1 and the cover 2 both have a vertically extending corrugation 5. Especially with Lid 2, this corrugation increases the dimensional stability.

When the lower part 1 is only the inner side wall 16 and in the same way the inside of the Corrugated ring 18; the shape of the lower part 1 is essentially determined by the ring 18, so that the corrugation of the lower part 1 without further-ss can be dispensed with.

The cover 2 is made of thicker PVC film than the lower part 1, because here the film itself is the

Lid 2 must give sufficient dimensional stability.

To further reinforce the cover 2, it has four equally spaced around its circumference, vertically veiaufende grooves 30, which are open to the top and the outside and at the lower end by a circumferential, horizontal collar surface 34 of the lid 2, which suflisgt on the upper edge 6 of the lower part 1, are limited »In the grooves 30 from above in the direction of the arrow 33 is a filling body 31 made of rigid polystyrene foam pushed in as a support the support body 31 pushed in up to the lower end of the groove 30 stands with its top 32 by a small amount V over the upper open end of the groove 31 and over the Upper side of the lid 2 and can therefore act as a buffer when stacking the containers.

The support bodies 31 are enclosed in a C-shape by the groove 30 and are therefore held captive; i.e. the greatest clear width 'D' of the groove 30, measured in a horizontal section, is greater than its in the same Horizontal section measured opening width dl

When inserting the support body 31 must by hand these are not pushed in as far as the lower end 34 of the groove 30; this happens without further action when stacking the filled containers. 5

-Der Fig. 1 and 3 it can be seen that to achieve the space-saving stackability of the cover 2 and the one not yet provided with the ring 18 Lower part 1 before the container is used, the clear width of the lid 2 ury of the lower part 1 from Bottom 9 or 3 up to the edge 7 or 6, and the clear • width of the grooves 30 in the cover 2 from bottom to top steadily increasing. Furthermore, in the outer side wall 15 of the lower part 1 are distributed at least on the circumference two inwardly facing knobs 19 are provided, which prevent the lower parts 1 from being stacked be put together deeply. The segments of the ring 18 have depressions at corresponding points to accommodate the knobs 19.
