JP2584706B2 - A pleated package with an attachable pleated area - Google Patents

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

Description: FIELD OF THE INVENTION The present invention relates to convex or similar, made from thin pleated films, as described in patent FR 86 03956, additional application FR 88 03654 and patent FR 90 13589. The present invention relates to a package of articles having various shapes.

The prior art and its problems The above-mentioned patent describes a method of packaging by means of a package with asymmetrical folds fixed at the ends. The methods of the patents determine the shape of the pleats depending on the product to be packaged, but leave areas not covered by the package, and such areas may detract from product value Make defects. For some products, the shape is completely different from the shape of the rotating body, so the shape of the package may consume a lot of wrapping paper,
Alternatively, the appearance becomes extremely poor. For example, a sandwich called “octopus (TACO)” made by folding a semi-rigid pancake into two pieces and sandwiching meat and raw vegetables between them is semicircular. With the pleat structure described in the above patent, the semi-circular area can be covered properly, but it is difficult to create a proper pleat shape in the straight area. Also, when a pleated package as described in the above patent is installed around a hamburger, an uncovered area remains in the center of the hamburger so that when the hamburger must be grasped by hand, the hands are not soiled. Is not easy. In addition, some hamburgers require reinforcement to support vertical loads.

SUMMARY OF THE INVENTION An object of the present invention is to provide a package capable of appropriately packaging products having various shapes without using a large amount of wrapping paper and having good appearance.

SUMMARY OF THE INVENTION The present invention relates to all of the objects illustrated in the figures by providing, at the end of the pleated package, a pleated area generally made of a thin film or semi-rigid thin material, depending on the application. 1 (first
The problem is solved by adding (Fig.). No fold area 1

DETAILED DESCRIPTION OF THE INVENTION The length 3 (FIG. 1) and the width 4 of the unwrinkled area 1 are determined in each case depending on the product to be packed. In the case of the package of “octopus” 6 (FIG. 4),
A length 5 of a straight area is provided which corresponds approximately to the diameter of the circular pancake. The width 7 can be smaller than the spacing 8 between the fixed areas of the pleated pleats. In a preferred variant of the invention, the pleated area 9 is obtained by expansion of the pleated area, so that the packages can be cut off one by one as in the above-mentioned patent.

In the case of a hamburger package, the length 3 (FIG. 1) is substantially smaller than the hamburger diameter 10 (FIG. 2), while the width 4 (FIG. 1) is deployed around the hamburger. Center circular part 11 exposed from pleated part 12 (Fig. 3)
Is considerably larger than the distance 8 between the fixing areas of the pleats. This pleated area may be comprised of a film (FIG. 1) which is attached and secured to the end 14 of the pleated package 13, as in the aforementioned patent. If the film used is, for example, a paper / polyethylene composite, the unfolded area 1 to which it is attached is also composed of a paper / polyethylene composite. The polyethylene surface 15 of the unfolded area 1 to be attached is the paper side 16 of the edge 14 of the pleated package 13.
(FIG. 2) or polyethylene side 17 (FIG. 8) is secured to the edge 14 of the pleated package 13. In the case of welding between dissimilar materials with the polyethylene side attached to the paper side (FIG. 1), the welding position of the unpleasant zone 1 is in its final position on the same side as the product in which the polyethylene part 15 is to be packaged. It will be something like If welding is to be carried out between similar materials, the uncorrugated area 1 to be attached (FIG. 7) is placed on the pleated area 13 of the package at the time of welding and if it is folded back (FIG. 8), The zone supporting the polyethylene 15 of the zone 1 can be opposed to the product to be packaged.

When it is necessary to reinforce the strength of the hamburger against vertical load, for example, the height 20 of the hamburger 24 (the
10), and a piece of cardboard 18 (FIG. 9) having a width 21 substantially equal to the hamburger axis of symmetry 22 and a length 21 between its full circumference and half of it, for example. Can be installed. The cardboard piece 18 (FIG. 9) is made of, for example, a cardboard / polyethylene composite and is secured to the end 14 of the pleated portion of the package by welding between similar materials. As in the previous embodiment, the cardboard piece 18 is placed over the pleated area 13 of the pleated package, but the cardboard piece 18 (FIG. 10) is placed between the unfolded film 23 and the hamburger. It does not wrap as in the previous case, so that it can be broken. In this embodiment, the addition of a non-pleated area 25 (FIG. 11) for closing the central circular portion not covered by the fluted part 26 and the addition of a cardboard piece 27 for ensuring stability against load are performed. be able to.

When packaging "octopus", the "octopus" is placed on the upper half of the pleated area 9 (FIG. 4). Area without folds 9
The other half is folded over onto it, thereby partially covering the uncovered area of the pleated area. The "octopus" can be grasped by the folded film. After the above fold, folds 29
(FIG. 6) unfolded over the curved part 9
Just cover it. Needless to say, the shape and number of the pleats are determined according to the above-mentioned patent so as to cover the semi-circular area exactly. A similar process is used to pack hamburgers.
It is folded and held on both sides of FIG. 2 (FIG. 2) and covers the central area 11 (FIG. 3) which is not covered by the pleated area of the unfolded package 12. Compensating for the amount of film to additionally extend the unpleased area 1 (FIG. 1) by making the package with a lower coverage and thus less pleats determined according to the above-mentioned patent. Can be.

Finally, in connection with the reinforced cardboard piece 18 (FIG. 10),
The wrapper is placed as previously described and as described in the aforementioned patent, and the cardboard piece 18 is placed between the hamburger and the unfolded pleated film 23 to support the film. The unfolded film curves the cardboard piece into a semi-cylindrical shape particularly suitable for providing strength against vertical loads parallel to the axis 22. The advantage of such a configuration is that when the film is deployed around the hamburger 24,
Cardboard piece 18 that does not require the hamburger 24 to be completely wound
Is to maintain and fix the shape and maintain stability against vertical load. The cardboard piece may also be a heat insulator to prevent cooling of the packaged hamburger, and may be provided with an aluminum-coated surface for better insulation.

Effect of the Invention By providing a pleated area at the end of the pleated package, products of various shapes can be appropriately packaged with good appearance and without using a large amount of wrapping paper. For example, the package shown in FIG. 1 can cover the central circular portion (11) that is difficult to be packaged by the pleated package 13 in hamburger packaging. Therefore, the packaged hamburger can be held at the center without touching the hamburger. The package shown in FIGS. 4 to 5 is suitable for octopus (6) packaging and is not covered by the pleated area 9 by the pleated area 9 (center lower part of FIG. 6).
Can be wrapped. The octopus can be eaten without touching the octopus by holding the lower central portion of FIG. 6 covered with the pleated area 9 by hand. Also, by making the pleated area 9 of a semi-rigid material, it is possible to protect the octopus from being crushed. The unfolded area of cardboard pieces 18, 27, shown in FIGS. 9-11, reinforces the package and protects the package (e.g., a sandwich) from vertical loads on the packaged product so that it is crushed. Not to be.
