BRIEF SUMMARY
DESCRIPTION
The invention relates to coffins for the disposal of animal or human remains. These coffins are made of cardboard, fibre board, straw-type building board or hard board. Such materials are readily and inexpensively available, whereas there is a world shortage of suitable wood, and can reproducibly be cut in the necessary sizes without any need for matching. They are suitable for cremation and also for burial as they do not give rise to poisonous gases on burning, and decompose rapidly in the soil.
Cardboard coffins have previously been proposed, but it has proved difficult to design a model which can readily be erected to give the appearance of a conventional wooden coffin, and also have the necessary strength. An example of this is in U.K. Patent Specification No. 1,190,760, in which a moulding is provided around the periphery of the base so as not to impair the appearance of the coffin, and sufficient strength could not be obtained from cardboard of acceptable thickness. The problem of appearance particularly was faced in U.K. Patent Specification Nos. 1,291,836 and 1,305,623 which show complicated arrangements involving backing sheets and inset wooden fillets in the corners of the coffin. Another proposal U.K. Patent Specification No. 1,535,188 involves a large number of different blanks for the assembly of a single coffin, and this would involve the user in holding a very large stock of panels of different sizes. The invention provides a coffin, or a blank for erection into a coffin, cut from a sheet and comprising a base, side pieces and end pieces integral yet separated by crease lines, the side or end pieces having lateral extensions and means for connecting the side and end pieces in the erected coffin whereby the extensions support the adjacent side or end pieces.
The side or end pieces are preferably cut into adjacent extensions at angles such as to give upright corners when connected in the erected coffin. The connections may be by means of butt joints, dovetails or other interlocking means, preferably assisted by adhesive or stapling. The connections are preferably between adjacent side and end pieces, but may be with the base or between lateral extensions from side or end pieces. In the erected coffin, the extensions support the side or end pieces generally by lying inside them and being connected to them.
Strengthening strips may be included in the coffin or blank for adhesion along the upper sides of the erected coffin. These strips may be of double thickness, and one of the thicknesses may be cut away between the other and the side of the coffin to which it is to adhere so as to provide slots for securing a coffin lid. Tapes may be made to adhere around the outside and extend through the sides of the coffin for tying over the corpse and supporting coffin handles thereby strengthening the structure.
The coffin may include a coffin lid which fits inside an upper edge of the coffin and is secured to the strengthening strips. The coffin lid preferably has tongues projecting from its periphery for securing in the slots between the strengthening strips and the coffin sides. The tongues preferably have an edge nearer the foot of the coffin perpendicular to the periphery of the lid, and an edge nearer the head of the coffin inclined at less than 90.degree. to the periphery. The coffin lid preferably sits below the upper edge of the coffin to assist in retaining flowers.
A coffin according to the invention is preferably cut from a sheet of corrugated cardboard, single, double or treble fluted according to size, and faced with Kraft paper. A further coating of wood-effect or veneer paper may be applied to the outside before or after erection of the blank into a coffin. A coated paper may similarly be applied in or outside the coffin, or the cardboard may be waxed if desired. The blank may be cut using a cylindrical cutting machine, a set of knives for each size of coffin. Handles and reinforcement adhesive tapes may then be applied directly inside or outside the blank. The blank can be er
