DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to insulating foldable boxes for transportation and packaging purposes.
The technical field of the invention is that of manufacturing boxes or cases or other packaging volumes which can be folded in order to be transported in a minimum amount of space when empty.
BACKGROUND OF THE INVENTION
The main specific application of the invention is making such cases, or boxes, or other volumes which are insulating for the purpose of transporting or storing merchandise that need to be maintained at a temperature that is as stable as possible, in particular for small quantities of merchandise that are sensitive to extremes of temperature and to sudden changes of temperature, such as foodstuffs, pharmaceuticals, chemicals, etc. . . . .
One of the main applications of the invention is assembling such cases or boxes or other volumes which are self-supporting, stackable, and suitable for handling on pallets by forklift handling equipment.
Such foldable cases or boxes are known for transporting all types of merchandise, but without seeking to provide thermal insulation, and they are therefore unsuitable for the above purpose unless insulating panels are added to the insides of the walls once they have been assembled to create a packaging volume, thereby increasing the number of components required for building such a volume, complicating assembly, increasing the folded volume of the kit, and naturally also increasing its weight which is disadvantageous for transportation by air, and also decreasing the volume available for packaging, which makes such cases expensive.
In the field of foldable boxes and cases for packaging and transportation purposes, various patent applications are to be found, in particular for solving problems either to do with strength to enable them to be stacked, or else to do with manufacture, to reduce costs and to simplify assembly by optimizing the cutting out of mutually folding walls as well as possible. By way of example, to achieve the first objective, mention may be made of French patent application 2 654 703 published on May 24, 1991 in the name of ECOPAL for a "foldable pallet case". For that purpose, that document describes a rectangular pallet made essentially of wood, supporting a skirt which, in the deployed state, is in the form of a rectangular parallelepiped having open bottom and top faces, and in which each of two opposite transverse faces has a respective vertical fold line substantially in the middle subdividing it into two half-faces, thereby enabling said skirt to be folded concertina-like, and such as to enable it to be provided with two stiffening elements of shape and size corresponding substantially to the shape and size of said foldable transverse faces. Since the elements are fixed to the inside of the skirt, each to one of the two half-faces of the two transverse faces, they do indeed ensure that the pallet case is self-supporting and strong enough for them to be stacked with other such cases, while nevertheless making it possible for it to occupy a small volume once folded, given the ability of the kit to be disassembled and folded. Nevertheless, because the skirt is disposed as a continuous belt and includes two rigid elements on the insides of its foldable walls, the range of dimensions that are possible for the case is limited. Also, that disposition does not enable the other two faces also to be strong enough to be self-supporting, since that would not enable the set of side faces to hold together nor would it guarantee stability for the case as a whole. Furthermore, if it desired for such a foldable pallet case to be insulating, then it is still necessary to add pre-cut insulating elements inside it.
Mention may also be made of French patent 2 535 288 published on May 4, 1984, and filed by PAPETERIE LEON CLERGEAU and L'HEXAGONE, entitled "foldable self-supporting case for packaging and transport purposes and usable as a display unit". That document describes a foldable case in the shape of a rectangular paral
