Description

TECHNICAL FIELD The present invention relates to a paper tube coffin, and more particularly to a paper tube coffin provided with a reinforcing material that suppresses distortion of the paper tube and prevents the occurrence of gaps between the upper and lower paper tubes.

Conventionally, proposals have been made to make coffins made of paper such as corrugated cardboard for the purpose of reducing the weight of coffins, shortening the incineration time, suppressing fuel consumption, reducing carbon dioxide emissions, and protecting natural resources.
For example, in Patent Document 1 (Japanese Patent No. 6021469), a reinforcing beam material that is hardened over the entire length of the long side is formed at the connecting corner portion of the rectangular bottom plate portion (1) and the long side plate portion (2). A corrugated cardboard coffin is described in which (9) is cured and formed so that the longitudinal direction of the coffin body has practically sufficient load-bearing strength (especially see paragraph 0021 and FIGS. 1 and 2).
Further, in Patent Document 2 (Japanese Patent Application Laid-Open No. 11-113985), a storage portion (2) and a lid portion (3) are formed by cutting a cylindrical paper tube in half along its thrust direction. , The front part (22) and the rear part (23) of the storage part (2), which are formed by stacking paper strips, are formed of approximately semicircular plates, and the same approximately semicircular plates are formed. A coffin consisting of a front part (32) and a rear part (33) etc. of the lid part (3) is described (see in particular paragraphs 0012-0017 and FIGS. 1 and 2).
However, the corrugated cardboard coffin described in Patent Document 1 has a problem that the structure is complicated in order to have sufficient load-bearing strength, and the amount of adhesive filler used is increased. The coffin using a cylindrical paper tube has a structure in which the paper tube is wound with paperboard in a spiral shape, so the storage part (2) and the lid part (3) may be affected by changes in humidity inside and outside the coffin and load There are problems such as distortion and a gap being likely to occur between the housing portion (2) and the lid portion (3).

Since the side portion is fixed about 1 cm inside from the end of the lower paper tube 2, the thumb can be put on when lifting the lower paper tube 2. - 特許庁
(4) Place the flat paper plate 18 on the upper surfaces of the chord portions 12 of the five paper bow plates 10 and the paper reinforcing plate 20, and if necessary, fix them to form a flat portion.
(5) An elliptical ring-shaped plate 21 is affixed and fixed to the inner surface side of the edge of an elliptical hole drilled in the upper surface of the upper paper tube 3 at one end to form the window portion 5 .
(6) The circular arc portion 23 of the paper crescent-shaped plate 24 is fixed inside the upper paper tube 3 by about the thickness of the paper disk 16 plus 1 cm from the end of the upper paper tube 3 with an adhesive or the like. Since the side portions are located about 1 cm inside from the ends of the upper paper tube 3, the upper paper tube 3 can be attached and detached by putting fingers on both ends.
(7) A paper semi-annular plate 27 is fixed to the central portion of the upper paper tube 3 with an adhesive or the like.

Modified examples of the paper tube coffin 1 of the embodiment are listed.
(1) In the embodiment, there are five paper bow plates 10, two paper arc plates 15, two paper discs 16, a paper flat plate 18, and two paper reinforcing plates 20. The crescent plate 24 and the paper semicircular plate 27 are both made of corrugated cardboard. good.
Also, in order to increase the heat insulation and strength of the plane portion, instead of or in addition to the paper plane plate 18, a material that is excellent in heat insulation and strength and is nonflammable or does not generate harmful substances even if it burns is used. A plate-like body may be used.
(2) In the embodiment, the dimensions of all the constituent members were described on the premise that a human corpse is encased in a coffin.
(3) In the embodiment, the two paper arc plates 15 were shaped (crescent-shaped) as shown in FIG. A shape may be used, and such a shape is referred to herein as a crescent or crescent.

(4) In the embodiment, the paper disk 16 having the same diameter as the inner diameter of the lower paper tube 2 was used to form the side surface portion, but FIGS. As shown in the figure, a composite made by pasting a paper disc 17 made of corrugated cardboard having the same diameter as the outer diameter of the lower paper tube 2 and a thickness of about 0.5 to 1 cm on one side of two paper discs 16. A paper disk may also be used, and a paper disk made of corrugated cardboard having the same diameter as the outer diameter of the lower paper tube 2 and a thickness of about 1 to 2 cm is surrounded by a paper disk whose inner diameter is the outer diameter of the lower paper tube 2. It is also possible to use a composite paper disk made by gluing rings of equal length of 2 to 3 cm.
By doing so, the paper disk is also fixed to the end surface of the lower paper tube 2, so that the distortion occurring in the lower paper tube 2 can be further suppressed.
(5) In the embodiment, the arc portion 14 of the paper arc plate 15 is fixed with an adhesive or the like inside by the thickness of the paper disc 16 from the end of the lower paper tube 2 .
