Abstract

A separate fold-free region (25) is used to cover those areas left uncovered by the folded packaging (26) when it is wrapped around an object. In an alternative embodiment, a separate semi-rigid strip (27) is used to make the packaging mechanically resistant to vertical loads.

Description

[Detailed description of the invention] A pleated packaging with a pleated area that can be attached The invention is based on patent FR 8603 No. 956, described in additional application FR 8803654 and patent FR 9013589 Convex or similarly shaped, made from thin pleated film, such as Concerning packaging for articles.

The above-mentioned patent discloses packaging by means of a wrapping with asymmetrical pleats secured at the ends. It describes how to do it. These patented methods require folding depending on the product to be packaged. The shape of the package is now determined, but there remains an area not covered by the package. and if such an area is completely different from the shape of the rotating body, then this Therefore, the shape of the packaging may cause a large amount of wrapping paper to be consumed or The view becomes extremely bad. For example, fold a semi-hard pancake in half and Santo, also known as TACO J, is made with meat and raw vegetables in between. The shape of the pitch is semicircular. In the roof structure described in the above patent, the semicircular area is Although it can be coated just fine, it is difficult to create the proper pleat shape in straight areas. or, If a pleated wrapper such as that described in the above patent is attached around the hamburger, It leaves an uncovered area in the center where you have to grab the burger with your hands. It's not easy to keep your hands clean when you have to. In addition, some kind of hamburger Gars require reinforcement to support vertical loads.

Figure 11 covers the area not covered by the pleated portion of the unfolded package. 2 shows a variant embodiment of the invention using a pleat-free area and a reinforcing strip at the same time; .

The present invention solves all of the problems shown in the drawings at the end of the pleated package. According to This can be solved by adding (Fig. 1). Area 1 without pleats is a pleated fill. The product may be fixed to the system by any suitable means, or alternatively, An integrally formed extended pleat-free area 2 (similar to a pleat element as described in Figure 4).

The length 3 (Fig. 1) and the radius 4 of the non-pleat area l are determined in each case by the packaging Determined depending on the product being manufactured.

In the case of "Octopus" 6 (Figure 4) packaging, the diameter is substantially the same as that of the circular pancake. An approximately corresponding straight section length 5 is given. For conduit 7, pleated The spacing between the fixed areas of the pleats can be less than 8.

In a preferred variant of the invention, the pleat-free area 9 is expanded by widening the pleat-free area. As a result, the packages can be separated one by one as in the above-mentioned patent. Become so.

In the case of a hamburger package, length 3 (Figure 1) is the diameter of the hamburger 10 (Figure 1). 2), but the radius 4 (Fig. 1) is substantially smaller than that of the hamburger. The central circular part 11 (Fig. 3) exposed from the unfolded pleated part 12 can be covered. As such, the distance between the fixed areas of the pleats is made considerably wider than 8. This pleated area is As in the case of the aforementioned patent, the attachment is fixed to the end 14 of the pleated packaging 13. (Fig. 1).

If the film used is e.g. a paper/polyethylene composite, the attached The unpleated area 1 is also composed of paper/polyethylene composite. No crimps mounted The polyethylene side 15 of zone 1 is connected to the paper side 16 ( (FIG. 2) or the edge 14 of the pleated package 13 with the polyethylene side surface 17 (FIG. 8). The position is fixed at the position where the polyethylene section 15 is packaged in its final position. It is placed on the same side as the product. If welding is carried out between similar materials, installation The pleated area 1 (Fig. 7) that is removed is located above the pleated area 13 of the package during welding. and fold it back (Figure 8), the polyethylene in the non-pleat area 1 The area supporting 15 can be opposite the product to be packaged.

If you need to strengthen the hamburger against vertical loads, e.g. a width 19 substantially equal to the height 20 (FIG. 10) of the hamburger 24; The total circumference and half of this in the cross section perpendicular to the symmetry axis 22 of the Bano 1 burger A piece of cardboard 18 (FIG. 9) having a length 21 between can be attached. thickness The paper piece 18 (FIG. 9) is composed of a cardboard/polyethylene composite, for example, and It is secured to the pleated end 14 of the wrapper by welding between like materials. Previous As in the embodiment, the cardboard piece 18 is placed over the pleated area 13 of the pleated package. The cardboard piece 18 (Fig. 10) is placed on the unfolded film 23 and the hanger. Do not fold it back as in the previous case so that it is placed between the stomach.

In this embodiment, the central circular portion not covered by the pleated portion 26 is closed. In order to ensure the addition of a non-fold area 25 (Fig. 11) and stability against loads, This can be done together with the addition of a second cardboard piece 27.

When packaging an "octopus", the "octopus" is placed on the upper half of the non-fold area 9. (Figure 4). The other half of the pleated area 9 is folded back over it, thereby Partially covers areas that are not covered even when the pleats in the pleated area are developed. instructor The octopus can be grasped using the folded film. After the above turnaround, Develop the pleats 29 (Fig. 6) over the circular part and cover the non-folded area 9. Bye. Needless to say, the shape and number of pleats should be chosen to precisely cover a semi-circular area. determined according to the above-mentioned patent. A similar process is used to package hamburgers. Using a process, fold the pleated area 30 to both sides of the hamburger 31 (Fig. 2). central area 11 that retains and is not covered by the pleated area of the unfolded package 12; (Figure 3). The coverage determined according to the above-mentioned patent is lower, and By creating a package with fewer pleats, the pleat-free area 1 (Fig. ) can compensate for the amount of additional lengthening the film.

Finally, in conjunction with the reinforcing cardboard piece 18 (Fig. 10), the packaging is assembled as described above. , and placed as described in the above-cited patent, and the cardboard piece 18 is shaped like a hamburger. and the unfolded pleated film 23 to support this film. exhibition The film to be opened bends the cardboard piece, particularly under a vertical load parallel to the axis 22. The semi-cylindrical shape is suitable for providing strength. The advantage of such a configuration is that When the film is expanded around the hamburger 24, it does not completely cover the hamburger 24. Maintains and fixes the shape of cardboard piece J8, which does not need to be rolled up, and provides stability against vertical loads. It is to maintain it. The cardboard piece is also used to cool the wrapped hamburger. Aluminum also acts as a heat insulator to prevent It may also have a side with a side.
