DESCRIPTION Menu container

The invention relates to a menu container according to the preamble of claim 1.

05 In a known menu container of this type (DE-Ge utility model G 87 01 07^3.9) the lower part is either deep-drawn from sheet metal in one piece or the shells are welded together along the upper outer flanges. The welding can be difficult in this case.

10 In addition, you do not have a free choice of materials for the lower part.

The invention is based on the object of making a greater variety of materials usable for the lower part and of facilitating and improving the way in which adjacent shells 15 are connected to one another.

Ol This problem is solved by the features of claim 1. The mechanical connection eliminates the possible difficulties when welding the upper outer flanges. In addition, non-weldable materials can now also be used for the shells.

According to claim 2, the fold seam can in particular be a double fold seam. The material used is primarily fine sheet metal, e.g. aluminum sheet, tinplate and TFS (Tin Free Steel) sheet with a suitable surface finish, e.g. made of nickel or chrome. The interlocking elements of the fold seam can be designed in any suitable way. These elements can, for example, be pushed into one another, but can be inserted into one another from any direction, after which the actual fold closure takes place by pressing the elements together.

The clamps according to claim 3 also allow materials that cannot be folded to be connected to one another. These include, for example, deep-drawn plastic films.

The clamps can be either a temporary or permanent part of the mechanical connection. For example, it is sufficient to leave the clamps in place until the heat sealing of the closure onto the lower part is completed. After that, the clamps can be removed and returned to the manufacturing process. However, the clamps can also remain permanently in place in engagement with the upper outer flanges to stabilize the entire container.

The features of claim 4 result in a mechanical connection that can be produced particularly quickly and safely.

According to claim 5, the adjacent upper outer flanges can be pressed against each other with particularly favorable forces.

The features of claim 6 facilitate the attachment of the clamps to the upper outer flanges.

The external roll-up according to claim 7 stiffens the base part and also the upper outer flange considerably. This also facilitates heat sealing along the upper outer flange.

The features of claim G lead to a simplification of production.

According to claim 9, sufficient mechanical strength is achieved even with split external rolling.

The heat seal according to claim 10 can be applied relatively easily and safely and represents a cost-effective type of closure.

Further features and advantages of the invention will become apparent from the following description of embodiments based on the drawings. It shows:

Fig. 9 a part of the sheet metal blank of one shell from Fig. 8 and

Fig. 10 shows a part of the sheet metal blank of the other shell according to Fig. 8.

Fig. 1 shows a circular meal container 1, the lower part 2 of which is composed of three equally sized, sector-shaped shells 3, 4 and 5. Each shell 3 to 5 defines a chamber 6, 7 and 8 for accommodating a separate meal component. Each shell 3 to 5 is also provided with a circumferential upper outer flange 9, , 10 and 11. §

Adjacent shells 3 to 5 are connected to each other at the upper outer flanges 9 to 11 by a mechanical connection 12, 13 and 14. The mechanical connections 12 to 14 are each located below an upper level 15 jointly defined by the upper outer flanges 9 to 11 (Fig. 2 to 4) and

Oil in a space 16 between adjacent shells up to 5.

The mechanical connection 12 is designed as a clamp 17 that extends radially over almost the entire radius with respect to the lower part 2. The cross section and function of the clamp 17 in conjunction with the upper outer flanges 9, 10 correspond to those of the relatively short clamps 18 and 19 that form the mechanical connection 13. The clamps 18, 19 clamp the upper outer flanges 10, 11 together and serve on the outside and inside at the corresponding radius of the lower part 2 essentially for the relative fixing and positioning of the adjacent shells 4, 5.

\ Terminals 17 to 19 can also be connected to the lower part

j 15 can be removed and returned to the manufacturing process for reuse as soon as the lower part 2

\ with a closure not shown in Fig. 1

\ can be seen.

The mechanical connection 14 is formed by a folded seam 20 extending over practically the entire radius of the lower part 2. The outer edges of the upper outer flanges 9, 11 leading to the folded seam 20 can be designed before the completion of the folded seam 20 in such a way that the shells 3, 5 can also be brought into initial engagement with one another in the direction of the longitudinal axis of the lower part 2. In this way, all mechanical connections up to 14 of the lower part 2 can be designed as such folded seams 20.

Alternatively, all mechanical connections 12 to 14 could be made either with the long terminals 17 or the

Ol short terminals 18, 1.9 can be realized.

If folded seams 20 are used, the upper outer flanges 9 to 11, and usually also the associated shells 3 to 5 in total, are made of thin sheet metal.

Such a design is shown in Fig. 2 in the drawing. The thin sheet is provided with a heat-sealable lacquer layer on its surface facing the chamber B, 8. After the folded seam 20 has been completed, a closure 21, which is also heat-sealable on its underside and is designed as a metal foil, is sealed onto the upper level 15. Since this heat sealing of the closure 21 also takes place along the upper outer flanges 9 to 11 in the area of the mechanical connections 12 to 14, the chambers 6 to 8 are ultimately hermetically sealed against one another, so that the menu components cannot mix with one another before consumption.

As shown in Fig. 3, the shell 4 consists of deep-drawn plastic film. The mechanical connection 13 has, as can be seen particularly clearly in Fig. 4, hooks 22 and 23, which extend practically over the entire radius of the lower part 2 (Fig. 1) and downwards. The short clamps 18, 19 are pushed over the hooks 22, 23 from the outside. The clamps 17 to 19 are designed to be spring-loaded and therefore press the associated upper outer flanges 9 to 11 against each other with pre-tension in the assembled state according to Fig. 1, 3 and 4.

Fig. 5 shows the short clamp 18 in the pre-tensioned initial state, i.e. before its assembly. The clamp 18 has a V-shaped insertion hole on the side that first comes into contact with the upper outer flanges 10, 11.

In all drawings, equal parts are marked with equal &

% Reference numbers provided. M

Fig. 6 shows a substantially rectangular handle holder 25, the lower part 26 of which is composed of two substantially rectangular shells 27 and 28.

The outer flanges 3, 10 of the shells 27, 28 are connected to one another by the mechanical connection 14 designed as a folded seam 20. The folded seam 20 extends practically over the entire width of the lower part 26.

Instead of the mechanical connection 14, another mechanical connection corresponding to the mechanical connections 12, 13 in Fig. 1 could also be used in the embodiment according to Fig. 6. Then the shells 27, 28 could also consist entirely or partially of non-foldable material, e.g. plastic film.

Additional trays could also be connected in the same way to the long or end sides of the lower part 26 according to Fig. 6 using mechanical connections. Then you would have not only chambers and 30, but also additional chambers available for menu items.

The lower part 26 has a circumferential outer roll 31 formed at the free end of the upper outer flanges 9, 10. Each of the shells 27, 26 forms a part 32 and 33 of the outer roll 31. The parts 32, 33 overlap in the area of the mechanical connection 14 in the overlap length 34.

Fig. 7 shows that the fold seam 20 is of even lower

Ol height extension than the outer roll 31.

In Fig. 6 and 7, the closure 21 is omitted, but can be seen in Fig. 8. Here too, the closure 21 was hot-sealed onto the upper level 15 in a manner known per se.

In Fig _. 9, a part of a blank 35 made of sheet metal is shown, from which the shell 27 is later deep-drawn. The blank 35 has an edge strip from which the part 32 of the outer roll 31 is later made according to Figs. 6 to 8. In addition, the blank 35 has an edge strip 37, which later forms a hook of the folded seam 20. In the area of the overlap of the edge strips 36, 37, the blank 35 is provided with a slot 38, the length of which corresponds to the overlap length 34 (Figs. 6 and 8).

Fig. 10 shows a blank 39 made of thin sheet metal, from which the shell 28 is later deep-drawn. The part 33 of the external roll 31 is later created from an edge strip 40 of the blank 39 (Fig. 6 to 8). Another edge strip 41 of the blank 39 later forms the other hook of the fold seam 20.
