Description

Technical Field

[0001] The utility model belongs to the technical field of coffins, and in particular relates to a folding paper coffin. Background Art

[0002] Corrugated cardboard coffins have long been an alternative to wooden coffins. Compared to wooden coffins, corrugated cardboard coffins are lighter, have better flammability, and can be easily assembled by bending the cardboard. Therefore, corrugated cardboard coffins have attracted attention as environmentally friendly funeral supplies.

[0003] However, in the structure of assembled corrugated paper coffins, the traditional connection method is to connect through accessories such as screws. However, since the corrugated paper cloth does not have strength, the screws cannot be tightly engaged with the corrugated paper, which makes it easy for them to come loose during use. In addition, there will be metal residues after incineration, which requires the use of a magnet to absorb the screws in advance when collecting the ashes. In addition, during the long storage period of corrugated paper coffins, the hygroscopicity of the cardboard will cause the board to deform, thus affecting its use. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a folding paper coffin.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: A folding paper coffin, comprising a bottom plate, a front plate, a back plate and two side plates, a plurality of hinges are connected between the inner sides of the bottoms of the two side plates and the upper surface of the bottom plate, the outer surfaces of the two side plates are aligned with the side edges of the bottom plate, the front plate and the back plate are arranged between the front and rear ends of the two side plates, and the outer sides are aligned with the front and rear ends of the two side plates, the upper surface of the bottom plate and the lower surfaces of the front plate and the back plate are provided with bottom connecting pins connected to each other, The sides of the front plate and the rear plate are connected to the two side plates with side connecting pins.
