DESCRIPTION:
BRIEF SUMMARY
SUMMARY OF THE INVENTION
The present invention is concerned with a foldable coffin.
The invention is in particular aimed at providing a lightweight coffin, which when folded requires only little space, to facilitate its transport, while being very easy to assemble, without any tool and in any situation, and providing a rigid structure of a high strength.
The invention is also aimed at providing a coffin which can be used both for burial and for incineration, without any short term, medium term and long term adverse effects on the environment.
Another aim of the invention is to provide a coffin made of a material which is readily biodegradable.
To this end, the coffin according to the invention has the characteristic features that follow: A foldable coffin, characterized in that it is made by folding a blank cut out as a single piece from a sheet consisting substantially of cellulosic material, to form a plurality of panels providing the faces of the wall of the coffin, as well as assembling and reinforcing members for this wall, this blank exhibiting a plurality of preformed folding lines between the panels and parts thereof corresponding to the different faces of the wall of the coffin, as well as a plurality of openings arranged in such a manner that, upon folding and turning down of the different parts of said panels over one another, the respective openings of at least two of these panels are made to coincide with one another to make it possible to fasten together the panels by means of fastening members, arranged to be introduced through the openings while occluding the same and maintaining the edges thereof together. Additional optional characteristic features will be evident from the description of the invention that follows.
Advantageously, the material used for forming the walls of the coffin is in the form of a sheet, comprised of an inner part made of corrugated cardboard covered, on at least one of the two faces of the sheet, by one or several layers of a cellulosic coating material, colored and optionally decorated, for example to confer to the surface of the material the appearance or wood.
Preferably, the cellulosic material forming the coating layer or layers covering the two faces of the material consists of pure natural cellulose which had undergone no treatment by a chemical agent such as chlorine, fluorine, hydrochloric acid, hydrofluoric acid or chlorinated or fluorinated bleaching agents, this layer being stained by printing with a water colour and, optionally, slightly weathered by exposure to ultraviolet radiations.
The inner corrugated part of the sheet is preferably made of recycled paper, which was washed with water, without being subjected to any hydrochloric or hydrofluoric bleaching, and is assembled by means of an environmentally neutral adhesive.
The containment case which can be used inside the coffin is advantageously made of a material consisting of a base of corrugated recycled cardboard covered, on one face thereof designed for becoming the inner surface of the wall of the containment ease, by a thin film of polyester having, for example, a thickness in the order of 5 to 10 micrometers. Such a material is designed for resisting to corrosive liquids, in particular to the products generated by the decomposition of the corpse, such as amino acids, this material being however biodegradable per se and capable of withstanding without deformation, temperatures ranging from those of liquid nitrogen (approximately -180.degree. C.) to a maximum value in the order of +240.degree. C.
