Blanks for coffins

Claim 2

A blank for a coffin consisting essentially of the combination of a thin outer layer of a flexible material with high tensile strength forming the entire outer surface of the coffin, a plurality of rigid sheet sections attached to various portions of the inner side of said outer layer of flexible material, which rigid sheet sections are intended to be folded in an unobstructed edge-to-edge relationship to each other along lines parallel to their adjacent edges and directly abut against each other to form a coffin cavity using said flexible outer layer as a combined pivot and connecting member to hold the edges of said rigid sections together under tension in direct edge-to-edge abutting relationship, said outer surface extending beyond the sections forming the sides of the coffin so as to make flaps which can be fastened to the outer sides of the coffin, each of said rigid sheet sections having its inner surface covered with separate thin layers of material that extend beyond the edges of each rigid section so as to form outwardly extending edge flaps, the outwardly extending edge flaps of one rigid sheet section being fastened to the adjacent rigid sheet section when the coffin is assembled so as to both form a seal between adjacent rigid sheet sections and to lend structural stability to the coffin.

Claim 3

A blank according to claim 1 wherein the edges of said rigid sheet sections are contoured so that they will nest together when the coffin is erected under the influence of the tension forces exerted by the thin layer of flexible material.

Claim 4

A blank for a coffin characterized by a. a plurality of largely flat sections defined by essentially straight lines, which sections can be folded in relation to each other along interlying borderlines and joined together to form a coffin of the intended shape, b. a relatively thin layer forming the outer surface of the coffin, c. each of said flat sections comprising a rigid sheet, each rigid sheet being attached to said thin layer, d. said relatively thin layer being composed of a flexible material with high tensile strength and extending over the entire outer surface of the blank and constituting the only connection between the rigid sheets, e. said plurality of flat sections including two rectangular sections forming the top and bottom respectively of the coffin and which at their edges border onto sections that, when the coffin is assembled, form parts of its sides and ends, and f. lengthwise stiffeners mounted on the edges of the side-forming sections which, when the coffin is assembled, will rest against each other in the transition between the top and bottom part of the coffin and are elaborated with a lengthwise groove and a tongue corresponding to the groove.

Claim 5

A blank for a coffin characterized by a. a plurality of largely flat sections defined by essentially straight lines, which sections can be folded in relation to each other along interlying borderlines and joined together to form a coffin of the intended shape, b. a relatively thin layer forming the outer surface of the coffin, c. each of said flat sections comprising a rigid sheet, each rigid sheet being attached to said thin layer, d. said relatively thin layer being composed of a flexible material with high tensile strength and extending over the entire outer surface of the blank and constituting the only connection between the rigid sheets, e. said plurality of flat sections including two rectangular sections forming the top and bottom respectively of the coffin and which at their edges border onto sections that, when the coffin is assembled, form parts of its sides and ends, and f. lengthwise stiffeners mounted on the edges of the side-forming sections which, when the coffin is assembled, will rest against each other in the transition between the top and bottom part of the coffin and are elaborated with a lengthwise groove and a tongue corresponding to the groove.

Claim 6

A blank according to claim 3, wherein the stiffeners which are mounted on the sections forming the sides of the coffin are provided with pairwise opposite slits intended to receive bands intended for holding together and lifting of the coffin.

Claim 7

A blank according to claim 3, wherein the end surfaces of the sheets included in the sections which are not provided with stiffeners are bevelled in order when the coffin is assembled to form stable joints under the influence of tensile forces in the outermost layer of the blank.

Claim 8

A blank for a coffin characterized by a. a plurality of largely flat sections defined by essentially straight lines, which sections can be folded in relation to each other along interlying borderlines and joined together to form a coffin of the intended shape, b. a relative thin layer forming the outer surface of the coffin, c. each of said flat sections comprising a rigid sheet each rigid sheet being attached to said thin layer, d. said relatively thin layer being composed of a flexible material with high tensile strength and extending over the entire outer surface of the blank and constituting the only connection between the rigid sheets, e. said plurality of flat sections including two rectangular sections forming the top and bottom respectively of the coffin, between which a rectangular section forming one side of the coffin is located, wherein the section forming the bottom of the coffin borders at its three other edges onto three rectangular sections, which form the other side and respectively the ends of the coffin, the two sections forming the sides being elaborated to be folded in assembly of the coffin around stiffeners provided along the side edges of the bottom section, the stiffeners being mounted along the edges of the bottom-forming section being somewhat longer than the bottom of the coffin for formation of carrying handles.

Claim 9

A blank for a coffin characterized by a. a plurality of largely flat sections defined by essentially straight lines, which sections can be folded in relation to each other along interlying borderlines and joined together to form a coffin of the intended shape, b. a relative thin layer forming the outer surface of the coffin, c. each of said flat sections comprising a rigid sheet each rigid sheet being attached to said thin layer, d. said relatively thin layer being composed of a flexible material with high tensile strength and extending over the entire outer surface of the blank and constituting the only connection between the rigid sheets, e. said plurality of flat sections including two rectangular sections forming the top and bottom respectively of the coffin, between which a rectangular section forming one side of the coffin is located, wherein the section forming the bottom of the coffin borders at its three other edges onto three rectangular sections, which form the other side and respectively the ends of the coffin, the two sections forming the sides being elaborated to be folded in assembly of the coffin around stiffeners provided along the side edges of the bottom section, the stiffeners being mounted along the edges of the bottom-forming section being somewhat longer than the bottom of the coffin for formation of carrying handles.
