Description

[Technical field]

[0001] This invention relates to a coffin for pets that can be burned together with pets such as dogs and cats during cremation. [Background technology]

[0002] Pet coffins include coffin-like wooden ones as disclosed in the following Patent Document 1, but also cardboard ones (for example, Patent Document 2, etc.) This is thought to be because cardboard pet coffins can be manufactured more cheaply than wooden ones, can have a more glamorous appearance, and are more productive.

[0003] However, cardboard pet coffins are constructed by folding and inserting pieces of cardboard, and although they may have a beautiful appearance at first glance, the cross sections of the cardboard, as well as the joints and insertions, are visible, making them look cheap. Moreover, they are light in weight and do not have the solemn feel of a wooden coffin. Furthermore, they are prone to getting wet due to condensation caused by keeping the body cool or leakage of bodily fluids, which can cause them to lose their shape or the bottom to fall out.

[0004] Problems related to getting wet can be avoided by using a resin pet coffin as in Patent Documents 3 and 4. The coffin in Patent Document 3 is formed into a boat-shaped bag by closing both ends of a rectangular flexible polypropylene sheet material. The coffin in Patent Document 4 is composed of a main body on a bottomed box made of polystyrene foam, and a lid that is placed over the main body.

[0005] However, because these pet coffins are made of resin, they have a cheap feel, just like cardboard coffins, and lack the dignity and luxury of a traditional coffin. For this reason, cardboard coffins are more commonly used.

[0006] Even if the coffin is made of cardboard, it is possible to avoid the inconvenience of getting wet by laying a water-absorbing sheet on it. However, this requires advance preparation, and if preparation is neglected or insufficient, work such as transferring the body to a new coffin will be required.

[0007] In addition, cardboard coffins often cannot be burned together with pet remains during cremation. This is because the temperature of the crematorium is set lower than that of human cremation, and because of the substances contained in the cardboard, which discolor the bones or turn them black. Cardboard leaves a lot of residue after burning, making it difficult to distinguish between the residue and the bones, which makes it difficult to collect the bones.

[0008] Cardboard coffins have the above problems, but even wooden coffins have the drawback that the coffin may remain unburned because the temperature of the crematorium is low as mentioned above. To avoid this, it is best to increase the heat, but in that case, no bones will remain.

[0009] As such, pet coffins have their pros and cons depending on the material. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Japanese Utility Model Application Publication No. 60-27659 [Patent Document 2] JP 2005-229819 A [Patent Document 3] Patent Publication No. 2021-185935 [Patent Document 4] Patent No. 7175060 Summary of the Invention [Problem to be solved by the invention]

[0011] The main objective of this invention is to create a cemetery that can be manufactured at a lower cost than wooden cemeteries, while still having a sense of dignity and luxury, and that can be burned together with the remains of pets. [Means for solving the problem]

[0012] To this end, the present invention provides the following pet coffin, which includes a bottomed box-shaped container constructed by assembling plate materials, and a lid for closing the top opening of the container.

[0013] That is, the board is made of solid paperboard, and the paperboard has a core material made of compressed pulp and a printable coating layer formed on both sides of the core material. The lid is made of paperboard with the same structure as the paperboard constituting the container. Then, some of the sides formed by the intersection of the container and the lid with the plate surfaces of at least the container are formed by joining pairs of abutting end faces inclined with respect to the plate surfaces in the V-cut groove. The other sides are formed by joining abutting end faces inclined with respect to the plate surfaces.

[0014] In this configuration, the solid paperboard board makes the end faces of the container and the lid look like wood. In addition, the core material of the paperboard, which is made by compressing and molding the pulp, gives the feeling of thickness and weight like wood. The coating layer of the paperboard modifies the surface of the core material to express a desired texture, such as a smooth board surface, and also gives water resistance, and if printing is applied to the surface of the coating layer, the printing expresses a desired appearance, such as wood grain. At least the container, which is made of such paperboard board, has at least a part of the side connecting the vertices of the container and the lid, which is made of such paperboard board, made of V-cut grooves, so that the side looks beautiful and the assembly operation is easy and accurate. Moreover, the abutting end faces that make up all the sides, including the part made of the V-cut grooves, are solid as described above, so that the entire surfaces are joined to form a strong joint state. The pulp, which is the main material of the pet coffin, burns together with the pet's body during cremation with little soot or residue. Effect of the Invention

[0015] According to this invention, since the board material is made of paperboard having a core material and a coating layer, it is possible to construct a container and a lid body that are similar in thickness, weight, and texture to wood. For example, by printing a wood grain pattern on the surface of the coating layer, it is possible to express a more wood-like appearance. In this way, even though it is made of paperboard, it is possible to give the coffin a sense of dignity and luxury, just like a wooden coffin.

[0016] Moreover, because the plates are solid, the joints during assembly can be tightly joined without gaps, resulting in a strong assembly state for the body. As a result, the coffin has sufficient strength to withstand the storage, transportation and cremation of the corpse.

[0017] Furthermore, the main material of the boards is pulp, just like wood, and they are formed by compressing pulp, so they can be completely burned even at low temperatures and produce little soot, making them ideal for burning together with the remains of pets during cremation.

[0019] An embodiment of the present invention will be described below with reference to the drawings.

[0020] Fig. 1 is a perspective view of a pet coffin 11, and Fig. 2 is a perspective view of the coffin in a separated state. As shown in these figures, the pet coffin 11 comprises a bottomed box-shaped container 12 and a lid 13 that closes an upper end opening 12a of the container 12. The lid 13 is formed with an opening / closing window 14 that allows the pet's body contained inside to be viewed.

[0021] The container 12 is constructed by assembling plate materials 15, and the lid 13 is also constructed by assembling plate materials 15. The container 12 is a rectangular parallelepiped of a required volume that is rectangular in plan view, and has a bottom plate 21 and four side plates 22, 23 standing around it. The container 12 has four vertices t1 and t2 on the top and bottom, respectively, and the space inside the four upper vertices t1 is the upper end opening 12a described above. Here, among the sides formed by the intersection of the plate surfaces, the four sides connecting the corresponding vertices t1 and t2 on the top and bottom are defined as vertical sides s1, and the four sides connecting the four lower vertices t2 are defined as horizontal sides s2.

[0022] The cover 13 has the same rectangular parallelepiped outline shape as the container 12 in plan view, is thinner (lower in height in the vertical direction) than the container 12, and has a top plate 31 and four side plates 32, 33 hanging down from the periphery thereof. The cover 13 also has four vertices t3, t4 on the top and bottom, and the part inside the four lower vertices t4 faces the upper end opening 12a of the container 12. Here, of the sides formed by the intersection of the plate surfaces, the four sides connecting the corresponding vertices t3 and t4 on the top and bottom are defined as vertical sides s3, and the four sides connecting the four upper vertices t3 are defined as horizontal sides s4.

[0023] The opening and closing window 14 described above is formed in the center of the top plate 31 in the short side direction on one side in the longitudinal direction.

[0024] The plate material 15 constituting the container 12 and the lid 13 has the same structure. The plate material 15 is made of a solid paper board. Specifically, as shown in FIG. 3(a), the plate material 15 is flat and has the rigidity to be able to maintain a certain shape by itself. It is formed to have a thickness of, for example, 3 mm to 5 mm, or about 8 mm. As shown in FIG. 3(b), the structure includes a core material 51 made of compressed pulp, coating layers 52 formed on both the front and back sides of the core material 51, and a printing layer 53 formed on the coating layer 52.

[0025] The core material 51 is made of wood pulp. It is preferably made up of a mechanical pulp layer and chemical pulp layers on both sides of the mechanical pulp layer. Both the mechanical pulp layer and the chemical pulp layer are formed using 100% virgin pulp made directly from wood. The mechanical pulp layer uses light-colored wood pulp, and the chemical pulp layer uses bleached or unbleached chemical pulp.

[0026] To manufacture the core material 51, a raw material made of wood pulp and water is compressed while being dehydrated, and formed into a plate of a predetermined thickness.

[0027] The coating layer 52 is intended to modify the surface properties of the core material 51 to obtain the desired appearance, feel, mechanical properties, printability, etc., and is applied by selecting an appropriate coating material such as abrasive powder.

[0028] In this example, the coating layer 52 is composed of a pigment coating. Specifically, the coating layer 52 is composed of two layers, and each coating material is composed of a pigment and a binder. A cream-colored coating material is used for the lower layer that contacts the core material 51, and a white coating material is used for the surface layer that is exposed to the surface. The lower layer absorbs the unevenness of the core material 51 and becomes one with it, while concealing or making the color of the core material 51 less noticeable. The surface layer becomes one with the lower layer, smoothing the surface and eliminating the effect on printing when the printed layer 53 is formed. The white color of the surface layer is so beautiful that it can be used as a coffin even without printing.

[0029] As described above, the printed layer 53 has the color and grain pattern of wood (see Figs. 1 and 2), which are formed by printing on the coating layer 52 on both sides. For printing, an appropriate printer, such as a UV inkjet printer, is used in accordance with the properties of the coating layer 52.

[0030] The printed content of the printed layer 53 does not have to have a wood grain pattern, but may have other suitable patterns. It may also be a photograph of a pet or other memorable images. The printed layer 53 is not necessarily formed on the coating layers 52 on both sides, and printing on the surface that will become the inner surface of the coffin may be omitted.

[0031] The weight of a paperboard of this construction is approximately 550 g / m2 at a thickness of 1.0 mm. 2 ~570g / m 2 , 3.8mm thick, approximately 1700g / m 2 ~1800g / m 2 It depends on the moisture content, but for a comparison, let's take Japanese cypress as an example. The specific gravity of Japanese cypress is 0.41, so it is about 410 g / m2 for a thickness of 1.0 mm. 2 , 3.8mm thick, approximately 1556g / m 2 In the case of paulownia, if the specific gravity is 0.3, then the weight is approximately 300 g / m2 at a thickness of 1.0 mm.2 , 3.8mm thick, approximately 1139g / m 2 As such, the weight of the paper board when picked up is not much different from that of the wood commonly used for coffins, and considering that wooden coffins become slightly heavier when they absorb moisture, it is clear that the feeling of holding the board is closer to that of a wooden coffin.

[0032] 4 is a cut end view of the pet coffin 11 with the lid 13 separated, cut parallel to the short side direction at the portion other than the opening and closing window 14. The opposing portions of the container 12 and the lid 13 are formed with fitting portions 16 that fit together to determine their position. The fitting portions 16 are formed by bonding a paper board (plate material 15) of the same structure as the paper board (plate material 15) that constitutes the container 12. In addition, a reinforcing member 17 made of a paper board (plate material 15) of the same structure as the paper board (plate material 15) that constitutes the container 12 is laminated on the inner surface of at least one of the container 12 and the lid 13.

[0033] The fitting part 16 shown in Fig. 4 is configured with single-walled side plates 22, 23 on the container 12 side, and with side plates 32, 33 on the lid 13 side, and a reinforcing member 35 (17) made of paper board pasted on the inside surface of the side plates 32, 33. A protrusion 16a is formed at the lower end of the reinforcing member 35 (17) that protrudes downward from the lower ends of the side plates 32, 33 of the lid 13 and follows the inner surface of the upper end of the side plates 22, 23 of the container 12. In other words, the paper board that constitutes the fitting part 16 also serves as the reinforcing member 17. The length of the protrusion 16a is determined taking into consideration the fitting state and the ease of opening and closing.

[0034] The base material for forming the container 12 and the lid 13 thus constructed will now be described.

[0035] Of the sides formed by the intersection of the plate surfaces of at least container 12 and lid 13, some sides are formed by joining pairs of abutting end faces inclined relative to the plate surfaces in the V-cut groove, and the other sides are formed by joining abutting end faces inclined relative to the plate surfaces. In pet coffin 11 of the shape shown in Figures 1 and 2, both container 12 and lid 13 are rectangular parallelepiped in shape, so the base materials constituting container 12 and lid 13 both have V-cut grooves.

[0036] FIG. 5 is a development view showing the inner surface of the base material A1 constituting the container 12. As shown in this figure, the container 12 is composed of one base material A1. The base material A1 has a shape in which the portions that become the side plates 22 and 23 are arranged on the four sides of the portion that becomes the bottom plate 21. A V-cut groove 18 is formed in the portion that constitutes the four horizontal sides s2 surrounding the central bottom plate 21. The V-cut groove 18 has a pair of abutment end faces 18a that are inclined at 45° with respect to the plate surface (see FIG. 6(a)). On the other hand, the portion that constitutes the four vertical sides s1 has abutment end faces 18b that are inclined at 45° with respect to the plate surface, similar to the abutment end faces 18a of the V-cut groove 18 (see FIG. 6(b)).

[0037] Although not shown in Figure 5, if the printing layer 53 is to have a wood grain pattern, the longitudinal direction of the bottom plate 21 is the fiber direction, and similarly, the longitudinal direction of the side plates 22 arranged in the short direction is the fiber direction. On the other hand, the fiber direction of the side plates 23 located at both ends in the longitudinal direction should be oriented perpendicular or approximately perpendicular to the above. When printing a pattern other than wood grain, the printing direction of each part is set taking into account the assembled state.

[0038] 7 is a plan view of the base materials A2 and A3 that make up the lid 13, and a development view showing their inner surfaces. As shown in this figure, there are three base materials A2 and A3 of two types. One is the base material A2 that makes up the main body of the lid 13, and the other two are base materials A3 that make up the protruding piece 16a mentioned above and function as the reinforcing member 35 (17). The former is the main body base material A2, and the latter is the reinforcing base material A3 with protruding piece.

[0039] The main body base material A2 has a shape in which the portions that will become the side plates 32 and 33 are arranged on the four sides of the portion that will become the top plate 31. A V-cut groove 18 is formed in the portion that constitutes the four horizontal sides s4 that surround the central top plate 31. The V-cut groove 18 has a pair of abutment end faces 18a that are inclined at 45° with respect to the plate surface. On the other hand, the portion that constitutes the four vertical sides s3 has abutment end faces 18b that are inclined at 45° with respect to the plate surface, similar to the abutment end faces 18a of the V-cut groove 18.

[0040] A window opening 41 for forming the opening / closing window 14 is formed in a portion of the main body base material A2 where the opening / closing window 14 is to be formed. The window opening 41 in the illustrated example is rectangular in plan view. This window opening 41 is provided with an opening / closing plate 42 that fits into the window opening 41 as shown in Figs. 1 and 2. To maintain the opening / closing plate 42 fitted in, an auxiliary plate 43 that protrudes inwardly of the window opening 41 is fixed to the back surface of the window opening 41. It is sufficient to form the auxiliary plate 43 on two opposing sides. The auxiliary plate 43 in the illustrated example is provided on two opposing sides in the longitudinal direction of the top plate 31. The auxiliary plate 43 is formed in a rectangular shape and is adhesively fixed to the inner surface of the top plate 31. A paper board having the same structure as the paper board constituting the lid 13 is used for the auxiliary plate 43. In order to enable the opening and closing plate 42 to be opened and closed, an operating recess 44 consisting of a notch that penetrates in the thickness direction and is sized to fit within the protruding length of the auxiliary plate 43 is formed at a position corresponding to the auxiliary plate 43 on the edge, as shown in Figures 1 and 2.

[0041] The reinforcing base material A3 with protrusions is formed in a band shape corresponding to the length of two adjacent sides of the four horizontal sides s4, and since the top plate 31 is rectangular in plan view, a V-cut groove 18 is formed in a portion corresponding to the vertical side s3, which is closer to one side than the center in the longitudinal direction. The V-cut groove 18 has a pair of abutment end faces 18a inclined at 45° with respect to the plate surface. In addition, abutment end faces 18b inclined at 45° with respect to the plate surface are formed at both ends in the longitudinal direction.

[0042] The width w1 of the reinforcing base material A3 with a protrusion is formed to be greater than the height h1 of the side plates 32, 33 of the main body base material A2. In other words, when one end face extending in the longitudinal direction of the reinforcing base material A3 with a protrusion is joined to the inner surface of the top plate 31, the other end face is set to protrude a predetermined length beyond the end faces of the side plates 32, 33 of the main body base material A2.

[0043] Although not shown in Figure 7, when the printing layer 53 is printed with a wood grain pattern, the longitudinal direction of the main body base material A2 is the fiber direction for the top plate 31, and similarly, the longitudinal direction of the side plates 32 arranged in the short direction is the fiber direction. On the other hand, the fiber direction of the side plates 33 located at both ends in the longitudinal direction should be orthogonal or approximately orthogonal to the above. When the printing layer 53 is printed with a wood grain pattern for the protruding reinforcing base material A3, the longitudinal direction is the fiber direction. When printing a pattern other than wood grain, the printing direction is set taking into consideration the assembled state.

[0044] As mentioned above, the printing direction of the base material A1 of the container 12 and the main body base material A2 constituting the lid 13 can be partially changed. However, for example, as shown in Fig. 8, by changing the arrangement of the parts corresponding to the side panels 22, 23, 32, 33, it is possible to express a wood grain pattern or the like as desired without partially changing the printing direction. That is, the side panels 23, 33 to be formed adjacent to one end in the longitudinal direction of the side panels 22, 32 arranged on both sides in the short direction are formed via a V-cut groove 18. Although Fig. 8 shows the base material A1 of the container 12, the same is true for the main body base material A2 of the lid 13.

[0045] The base materials A1, A2, and A3 are assembled into the container 12 and the lid 13 as follows.

[0046] That is, the base material A1 of the container 12 is obtained by applying an adhesive (adhesive) to the V-cut groove 18 and the other abutting end faces 18b, and bending the side plates 22, 23 upright at the V-cut groove 18. The adhesive to be used is one with good water resistance.

[0047] Like the base material A1 of the container 12, the main body base material A2 and the protruding reinforcing base material A3 of the lid 13 are coated with adhesive on the V-cut grooves 18 and other abutting end faces 18, and are folded at the V-cut grooves 18. The two protruding reinforcing base materials A3 are then combined together to form a rectangular frame and bonded to the inner faces of the side plates 23, 33 of the main body base material A2. At this time, the end faces extending in the longitudinal direction of the protruding reinforcing base materials A3 are butted against the inner face of the top plate 31 for bonding.

[0048] The pet coffin 11 configured as above is used to store the pet's body, and to lay it to rest, perform a funeral, transport it, and cremate it. In other words, after storing the pet's body in the pet coffin 11, it is burned together with the pet's body.

[0049] The body is placed in the container 12 with the lid 13 open, together with ice packs, etc. When the lid 13 is closed after the body is placed in the container 12, the internal space of the pet coffin 11, including the opening and closing window 14, is sealed off from the outside world.

[0050] The abutting end faces 18a, 18b of the container 12 are all joined with an adhesive, and the end faces of the paperboard are not exposed to the inside of the container 12. Therefore, there is no risk of liquid leaking out of the container 12 or seeping in through the abutting end faces 18a, 18b. Moreover, the paperboard constituting the container 12 has coating layers 52 on both sides, which prevents liquid from seeping in through the faces. The lid 13 that covers the container 12 can also be made water-resistant.

[0051] The pulp-based paperboard that constitutes the container 12 and the lid 13 is solid, unlike corrugated cardboard, and the edges that appear on the top end of the container 12 and the bottom end of the lid 13 look like edges of wood. Furthermore, the paperboard is formed to an appropriate thickness that provides rigidity, and can be made to have an appropriate sense of weight similar to wood, rather than the light weight of corrugated cardboard. For this reason, the coffin does not give a cheap impression, and gives a sense of solidity when handled, making it a solemn and luxurious coffin.

[0052] Furthermore, since the abutting end faces 18a, 18b are solid, strong adhesion can be achieved, and high joint strength can be obtained. The joint strength can also be achieved by forming some of the sides with V-cut grooves 18. That is, the sides formed with the V-cut grooves 18 connect the plate surfaces together, and have high unity. For this reason, the other sides not formed with the V-cut grooves 18 can also be easily joined as desired by bending. In this way, in addition to being resistant to moisture, the coffin can be made resistant to loads and impacts, and is suitable not only for placement but also for transportation. In addition, not only the sides formed with the V-cut grooves 18 but also the other sides have beautiful edges with sharp corners.

[0053] When the lid 13 is closed, the container 12 and the lid 13 are fitted together at the fitting portion 16, providing a sealed state. Furthermore, the protruding piece 16a that constitutes the fitting portion 16 is formed on the reinforcing member 17, so the fitting structure can be efficiently and simply formed and reinforced. Since reinforcement can be performed, even large coffins suitable for large dogs can be manufactured.

[0054] The opening and closing window 14 is configured so that the opening and closing plate 42 can be detached and fitted, and the opening and closing plate 42 is held by the auxiliary plate 43 provided on the back side of the window opening 41, so the structure is simple and can be manufactured at low cost. Furthermore, because it is easy to handle and has a simple structure, unexpected damage can be suppressed and there is no disruption to the funeral.

[0055] All materials, including the reinforcing member 17, are paperboards of the same structure, so that the overall appearance can be unified, and since the paperboards are mainly made of wood pulp, they can be obtained at a lower cost than those manufactured by processing wood.

[0056] Furthermore, paperboard made from wood pulp does not produce soot like cardboard and can be burned at a low temperature, so even if it is burned together with the remains of a pet, the bones can be easily collected.

[0057] Below, we will explain other examples of the pet coffin 11. In this explanation, the same parts as those in the above-mentioned configuration are given the same reference numerals, and detailed explanations thereof will be omitted.

[0058] 9 shows a cross-sectional structure of another example of a pet coffin 11. In the pet coffin 11 of this example, the fitting portion 16 of the container 12 and the lid 13 is configured in the opposite manner to that of the example of FIG.

[0059] That is, the reinforcing member 25 (17) is attached to the side plates 22, 23 of the container 12, not to the lid 13, to form the protruding piece 16a.

[0060] In the pet coffin 11 having this configuration, the strength of the container 12 can be improved.

[0061] FIG. 10 shows another example of a pet coffin 11, which has a reinforcing member 26 (17) on the inner surface of the bottom plate 21 in addition to the reinforcing member 25 (17) of the pet coffin 11 in FIG.

[0062] These reinforcing members 25, 26 can be made of a base material having the same configuration but different sizes from the base material A1 (see FIG. 5) that constitutes the container 12. In other words, the base material is configured such that the reinforcing members 25 are disposed on all four sides of the reinforcing members 26 via V-cut grooves, and the reinforcing members 26 have abutting end faces at the edges that will be joined together.

[0063] In the pet coffin 11 having this configuration, the strength of the container 12 can be further improved.

[0064] FIG. 11 shows another example of a pet coffin 11, in which a reinforcing member 36 (17) is attached to the inner surface of the lid 13. The lid 13 is formed in a rectangular shape corresponding to the shape of the container 12 in a plan view, and is a flat plate. The reinforcing member 36 (17) is also flat, and is one size smaller than the lid 13. Specifically, the reinforcing member 36 (17) is sized to fit into the upper end opening 12a of the container 12. In other words, the reinforcing member 36 (17) reinforces the shape of the lid 13 by being attached and laminated to the lid 13, and the four end faces 36a located at the outer periphery form protruding pieces 16a that fit along the inner surfaces of the upper ends of the side plates 22, 23 of the container 12.

[0065] A through window 36b is formed in a portion of the reinforcing member 36(17) corresponding to the window opening 41, the through window 36b being smaller than the window opening 41 in at least one of the longitudinal and lateral directions of the reinforcing member 36(17).

[0066] In the pet coffin 11 having this configuration, a fitting structure can be formed between the lid 13 and the container 12 while keeping the height of the lid 13 low.

[0067] Fig. 12 shows another example of a pet coffin 11, in which reinforcing members 25, 26, 36 are attached to the inner surfaces of the container 12 and the lid 13. Of the reinforcing members 25, 26, 36, the reinforcing member 25 (17) attached to the inner surfaces of the side plates 22, 23 of the container 12 is made lower in height than the side plates 22, 23 of the container 12, unlike the example shown in Fig. 10. In addition, the lid 13 is formed in a flat plate shape as shown in Fig. 11, and the four ends of the reinforcing member 36 (17) laminated on its inner surface are formed with hanging pieces 37 that become protrusions 16a that fit along the inner surfaces of the upper ends of the side plates 22, 23 of the container 12. 7, these hanging pieces 37 can be formed of a base material having V-cut grooves on all four sides of the reinforcing member 36, with abutting end faces on the edges of the hanging pieces 37 that will be joined together. The height h2 of the hanging pieces 37 is equal to or smaller than the difference in height h3 between the upper end surface of the container 12 and the upper end of the reinforcing member 25 (17).

[0068] In the pet coffin 11 of this configuration, the entire inner surfaces of the container 12 and the lid 13 are reinforced, further improving strength, and a large coffin can be obtained without using a thick paper board.

[0069] FIG. 13 shows the inner surface of the base material A1 for forming the container 12 of the pet coffin 11 according to another example. In other words, the pet coffin 11 is not limited to a rectangular parallelepiped, and can be formed into an octagonal shape in plan view as shown in FIG. 13. The base material A1 for forming the container 12 of such a pet coffin 11 has a bottom plate 21 in the center, which is octagonal in plan view. Side plates 22 are arranged on both sides of the short side of the bottom plate 21, and other side plates 23, 24 are connected to both ends of the side plate 22 in the longitudinal direction. Side plates 24 to be formed at positions corresponding to the chamfered inclined surfaces located at the four corners are connected to the ends of one side plate 24, and side plates 23, 33 to be formed at both ends of the bottom plate 21 in the longitudinal direction are connected to the ends of one side plate 24. And, V-cut grooves 18 are formed between the bottom plate 21 and the side plate 22 and between the side plates 22, 24, 23. The inclination angle of the pair of abutment end faces of the V-cut groove 18 with respect to the plate surface is half the angle between the bottom plate 21 and the side plate 22, and between the side plates 22, 23, 24. Although the base material A1 of the container 12 is shown in Fig. 13, the main body base material A2 of the lid 13 has the same configuration.

[0070] The lid 13 may be tall as shown in FIGS. 4, 9 and 10, or may be flat as shown in FIGS.

[0071] The above configuration is one embodiment for carrying out the present invention, and the present invention is not limited to only the above configuration, and other configurations can also be adopted.

[0072] The printed layer 53 on the surface of the coating layer 52 may not be present. In other words, printing may not be performed. The printed layer 53 may be formed only on the visible portion, not on the entire surface of the coating layer 52 on both sides. In other words, the printed layer 53 may not be formed on the portion to be bonded.

[0073] All bonding and fixing may be performed using double-sided adhesive tape or adhesive tape instead of adhesive.

[0074] The shape of the lid body 13 does not have to be a flat shape for the entire top plate 31, and may be other shapes, such as a kamaboko shape.

[0075] The shape of the opening / closing window 14 may be any shape other than a rectangle. The opening / closing window 14 may be configured to be opened and closed by rotating an opening / closing plate 42 fixed by a hinge. The opening / closing window 14 may be omitted, and a see-through window through which the inside can be seen may be formed in place of the opening / closing plate 42.

[0076] The lid 13 may be fitted to the container 12 in a slidable manner as shown in Fig. 14. That is, the lid 13 is basically formed as a single plate, and slide grooves 12b into which the sliders 13a on both the left and right sides of the lid 13 are slidably fitted are formed in the upper opening 12a of the container 12. The slide grooves 12b can be formed by cutting the plate material 15. The grooves can also be formed by bonding plate materials together. In addition, although it has been stated above that "the lid 13 is basically formed as a single plate," this indicates that the plate material may be overlapped, for example, at the boundary portion between the portion of the lid 13 that fits into the slide grooves 12b (slider 13a) or at the portion other than the slider 13a.
