Description

The present invention relates to a container for forest burial, and more particularly to a container for burying ashes when performing forest burial.

Forest burial has become widespread in recent years. This forest burial is also called a tree burial, and is a funeral method in which the ashes are buried around the tree as a symbol (gravestone).

Places for forest burial include temples that have been approved as graveyards and dedicated areas set up in part of the reien, and there are also forest graveyards where the entire reien is dedicated to tree burial.

Behind the growing need for forest burial is the need for graveyards in places that are easily accessible from residential areas due to the concentration of population in urban areas, and the demand for reductions in graveyard costs due to the declining birthrate. Due to the increase in the number of singles, the demand for conventional graveyards that are supposed to be used for a long time is decreasing, but in addition to these, there is a demand for burial methods that can fulfill the desire to return to nature. Conceivable.

In addition, there are the following patent documents 1 to 5 as documents that disclose an urn, which is a container for burying ashes.

Utility Model Registration No. 2581104 Japanese Unexamined Patent Publication No. 2009-56120 Japanese Unexamined Patent Publication No. 2010-136963 Utility Model Registration No. 3197640 Utility Model Registration No. 3203652

By the way, in forest burial, ashes are generally stored in a bag or an urn, and then buried in a grave hole section (carrot / bone burial chamber) formed in the ground with concrete or the like.

However, most of the urns are made of ceramics, and they are vulnerable to impacts, and there is a problem that the stored ashes deteriorate over time due to the invasion of rainwater, dust, and insects (the same applies when using a bag). For this reason, although there have been proposals for urns capable of improving the airtightness and protecting the internal ashes as in Patent Documents 1 to 3, these urns are not necessarily suitable for forest burial.

This is because, in recent years, there have been many requests for burial with spouses, relatives, or pets, but the above urns cannot accommodate the remains of multiple people and cannot meet such requests. be.

On the other hand, Patent Document 4 discloses an urn capable of accommodating the ashes of a plurality of persons.

However, since the urn described in Patent Document 4 has a structure in which the ends of a plurality of accommodating portions for accommodating ashes are inserted and connected in a nested manner, high processing accuracy is required and the manufacturing cost is increased. Further, since the structure is such that the end portion of the accommodating portion is simply inserted, the same problem as the above-mentioned existing urn, in which the accommodating ashes deteriorate due to the invasion of rainwater, dust, insects, etc., may occur.

Furthermore, in forest burial, the ashes may be taken out and moved to the grave after several decades (for example, 33 years or 50 years later), and the urn containing the ashes is no longer needed at this time, but the urn There is a problem that it is difficult to dispose of. Because of the peculiarity that the ashes were contained, there are few urn collectors to dispose of as industrial waste.

On the other hand, in order to solve such a problem, the applicant has previously proposed the device described in Patent Document 5.

However, this device leaves room for further improvement in terms of manufacturing costs. Specifically, in the present invention, the outer lid that closes the upper surface opening of the outer container is fixed to the outer container body by a screw structure such as a screw cap. According to such a structure, the inner surface of the outer lid and the outer container are fixed. Since screws must be formed on both sides of the peripheral edge of the main body, a mold for molding the outer lid and a mold for molding the outer container are required to provide it as a mass-produced product, which makes it difficult to increase the manufacturing cost. There is.

Therefore, an object of the present invention is to provide an ashes storage container suitable for forest burial, which is expected to increase in the future, at a low manufacturing cost.

In order to solve the above-mentioned problems and achieve the object, the forest burial container according to the present invention is a container for accommodating ashes and burying them in the ground for forest burial, and the container is for storing the ashes. An inner container body with a bottomless lid that has an inner container opening and can accommodate ashes inside, two or more inner containers having an upper lid that can open and close the inner container opening, and an outer container that accommodates the inner container. A bottomed and uncovered outer container body that has a container opening and can accommodate two or more inner containers stacked vertically inside, an outer lid that closes the outer container opening so that it can be opened and closed, and an outer lid that closes the outer container body It is provided with an outer container having an outer lid locking means for detachably fixing the outer lid.

Further, the outer lid has a disk-shaped outer lid top plate capable of covering the outer container opening and a ring-shaped outer lid side wall that rises from the peripheral edge of the outer lid top plate. An outer lid fitting portion having an outer diameter smaller than that of the outer lid side wall and being inserted into the outer lid side wall to be fitted with the outer lid is provided at the upper end portion thereof, and the outer lid locking means is the outer lid fitting portion. An outer lid locking projection provided on either one of the outer peripheral surface and the inner peripheral surface of the outer lid side wall, and an outer surface provided on the other of the outer peripheral surface of the outer lid fitting portion and the inner peripheral surface of the outer lid side wall. The outer lid locking groove includes the lid locking groove, and the outer lid locking groove receives the outer lid locking protrusion when the outer lid is put on the outer container body to close the outer container opening, and the outer lid locking protrusion is vertically oriented. The vertical groove of the outer container that extends vertically so that it can be moved, and the outer lid locking protrusion moves vertically through the vertical groove of the outer container, and then the rotation is accompanied by the relative rotation operation between the outer container body and the outer lid. It has a substantially L-shaped overall shape by providing an outer container horizontal groove portion that extends horizontally from the tip end portion of the outer container vertical groove portion so that it can move in the direction.

Then, the outer lid is fitted to the outer lid fitting portion of the outer container body, the outer lid locking projection is moved vertically along the outer container vertical groove portion, and then the outer lid and the outer container body are relatively rotated. When the outer lid locking protrusion is moved horizontally along the horizontal groove of the outer container, the outer lid is locked to the outer container main body and the outer container main body is closed by the outer lid.

In the present invention, the ashes are placed in an inner container, the inner container is stored in the outer container, and the outer container is buried in the ground or housed in a bone burial chamber or the like for burial.

The inner container has an inner container main body for accommodating the ashes and an upper lid for closing the opening of the inner container main body. On the other hand, the outer container has a cylindrical overall shape, and a plurality of inner containers can be stored inside by stacking them in the vertical direction (height direction). The top surface of the outer container is closed by an openable and closable outer lid so that the inner container can be taken in and out.

Therefore, when you want to take out the buried ashes, for example, when performing a burial or splitting, open the outer lid and take out the inner container from the storage space of the outer container, and open the upper lid of the inner container to store it in the inner container body. You can take out the ashes that have been made.

In addition, since a plurality of inner containers can be stored in the outer container, it is possible to meet the demand for burial with a spouse, relatives, pets, or the like. Further, since the ashes are protected by the double structure of the inner container and the outer container, that is, the ashes are stored in the inner container and then further stored in the outer container, deterioration of the ashes can be prevented.

Also, for example, if one of the couples is to be buried first and the remaining person is to be housed in the same outer container later and buried, it is only necessary to open the outer container at the time of later burial. Since the ashes buried are stored in an inner container separate from the inner container for later burial and it is not necessary to open it, the ashes buried earlier will not be damaged by the burial act in later years. In this respect as well, according to the present invention, the ashes can be maintained in a good condition.

Further, in the present invention, unlike the container previously proposed by the applicant, the outer lid for closing the outer container is not a screw-type locking means but a locking structure using a locking projection and a locking groove. , The manufacturing cost of the container can be reduced.

In particular, it is assumed that the outer container main body has a bottomless outer peripheral wall made of a pipe member having a constant outer diameter and inner diameter, and an outer bottom lid that closes the bottom surface of the outer peripheral wall, and the outer lid locking protrusion. Is provided on the inner peripheral surface of the outer lid side wall, and the outer lid locking groove is preferably provided on the outer peripheral surface of the outer lid fitting portion. This is because it is possible to manufacture the container at a lower cost by making it possible to form the outer peripheral wall of the outer container body by using a general-purpose pipe member such as an ABS resin pipe or a vinyl chloride pipe. ..

The outer lid locking groove is provided on the outer lid fitting portion (outer container main body) side so that the outer container main body can be formed without using a mold. That is, according to such a structure, even when mass-producing containers, a general-purpose pipe member is used (cut to a predetermined length) without using a mold when manufacturing the outer container body. It is possible to manufacture the outer peripheral wall of the outer container body by a simple operation of digging a groove (outer lid locking groove) on the outer surface of the upper end portion of the pipe member.

In this case, the outer bottom lid is, for example, a disk-shaped outer bottom lid body that can cover the bottom surface of the outer peripheral wall, and a ring-shaped outer bottom lid that rises from the peripheral edge of the outer bottom lid main body along the outer peripheral surface of the outer peripheral wall. The bottom surface of the outer peripheral wall may be closed by having a side wall and inserting and fixing the lower end portion of the outer peripheral wall into the side wall of the outer bottom lid.

Further, it is preferable that the outer lid locking projection has a columnar shape protruding from the inner peripheral surface of the outer lid toward the central portion of the outer lid. This is to make it easier for the outer lid locking projection to enter the vertical groove portion of the outer container when the outer lid is put on the outer container body. That is, if the outer lid locking projection has a columnar shape, the curved circumference of the locking projection when the outer lid locking projection enters the groove from the upper edge of the vertical groove portion of the outer container. Since the surface (cylindrical round peripheral surface) makes it difficult for the locking projection to be caught in the corner of the upper edge of the groove, the outer lid locking projection is smoothly fitted into the vertical groove of the outer container to attach the outer lid to the outer container body. It can be installed.

Further, if the locking projection has a cylindrical shape, the groove width of the outer lid locking groove can be made small and the width dimension of the vertical groove portion and the horizontal groove portion can be made the same. Can be reduced. Specifically, for example, if the locking projection is wide (the dimension in the horizontal direction is large), the groove width of the outer container vertical groove portion must be increased in accordance with the width dimension of the projection of the protrusion. Further, if the locking projection has a long shape in the vertical direction, it is necessary to increase the groove width (dimension in the vertical direction) of the horizontal groove portion of the outer container. On the other hand, if the locking projection has a cylindrical shape (circular cross section), the groove widths of the outer container vertical groove portion and the outer container horizontal groove portion can both be the minimum and the same groove width that is allowed in terms of strength. Therefore, it is possible to reduce labor and complexity during grooving as compared with the case where a wide groove or a groove having a different groove width is formed between the vertical groove portion and the horizontal groove portion.

It is preferable that both the outer container (outer container body and outer lid) and the inner container (inner container body and upper lid) are made of a material mainly composed of a resin (for example, ABS resin, polyvinyl chloride, etc.). This is to reduce the manufacturing cost of the container. Further, according to the resin material, it is possible to incinerate, dissolve, and recycle, and it is possible to facilitate disposal and disposal at the time of enshrining. Further, if it is made of resin, the material itself is more flexible than that of ceramics and the like, so that it can be made strong against impact and is less likely to be damaged. In addition, even in the event of a large-scale disaster such as an earthquake, the double structure of a resin container (outer container and inner container) that is not easily damaged can protect the ashes, and the name of the mourner or deceased can be engraved on the container. If this is the case, it is possible to immediately determine who the remains are, and it is possible to prevent the formation of unnamed bones.

In addition, the outer container may have a cylindrical overall shape and its height dimension may be larger than three times its diameter. If the outer container (and therefore the entire container) has a vertically long shape in this way, even if the ashes of multiple people (two or more inner containers) are stored inside, the width will not be taken, so the distance from the neighbor should be reduced. It is possible to bury more ashes per unit area of the burial place.

As a specific structure for closing the inner container body with the upper lid, for example, the following structure can be adopted.

The inner container has an upper lid locking means for detachably fixing the upper lid to the inner container body, and the upper lid stands from a disk-shaped upper lid top plate capable of covering the inner container opening and the peripheral edge of the upper lid top plate. The inner container main body has a ring-shaped upper lid side wall that is lowered, and the inner container main body is provided with an upper lid fitting portion that has an outer diameter smaller than the inner diameter of the upper lid side wall and is inserted into the upper lid side wall to be fitted with the upper lid. Further, the upper lid locking means includes an upper lid locking projection provided on either one of the outer peripheral surface of the upper lid fitting portion and the inner peripheral surface of the upper lid side wall, and the outer peripheral surface of the upper lid fitting portion and the inner peripheral surface of the upper lid side wall. Includes an upper lid locking groove provided on the other of the two.

The upper lid locking groove has a substantially L-shaped overall shape. More specifically, when the upper lid locking groove closes the opening of the inner container and the upper lid is put on the inner container body, the upper lid locking projection is received and the upper lid locking projection can be moved in the vertical direction. The inner container so that the extending inner container vertical groove and the upper lid locking protrusion can move in the rotation direction in accordance with the relative rotation operation between the inner container body and the upper lid after the upper lid locking projection moves vertically in the inner container vertical groove. It is provided with an inner container horizontal groove portion that extends horizontally from the tip portion of the vertical groove portion.

Then, the upper lid is fitted to the upper lid fitting portion of the inner container body, the upper lid locking projection is moved vertically along the vertical groove portion of the inner container, and then the upper lid and the inner container body are relatively rotated to rotate the upper lid locking projection. Is moved horizontally along the horizontal groove of the inner container, and the inner container body is closed in a sealed state by the upper lid.

Further, when the closing structure as described above is adopted, a latch mechanism for preventing the relative rotation of the upper lid and the inner container body in the closed state in which the inner container main body is closed by the upper lid may be further provided. This is to prevent the upper lid from being inadvertently loosened and the inner container body from being sealed, or the inner container containing the ashes from being inadvertently opened.

Specifically, the latch mechanism includes a recess provided in one of the upper lid locking protrusion and the inner container horizontal groove portion, and a convex portion provided in the other of the upper lid locking protrusion and the inner container horizontal groove portion. Has. This convex portion can be fitted to the concave portion, and the convex portion fits into the concave portion in the closed state in which the inner container main body is closed in a closed state by the upper lid to prevent the relative rotation of the upper lid and the inner container main body. do. If such a latch mechanism is provided, the contained ashes can be maintained in good condition for many years.

In the present invention, the number of inner containers to be stored in the outer container can be typically two or three, but four or more inner containers may be stored in the outer container. In addition, as the inner container, for example, a relatively large inner container for a large deceased person, a relatively small inner container for a small deceased person, and a smaller inner container for a pet are prepared. By preparing an inner container and multiple types of containers with different sizes (heights) for the outer container, burial can be performed with various combinations of the inner container and the outer container, and a variety of customers can be used. It will be possible to respond to needs in detail.

According to the present invention, it is possible to provide a container for containing ashes suitable for forest burial at a low manufacturing cost.

FIG. 11 shows a part of the inner container of the forest burial container according to the embodiment (a state in which the portion indicated by reference numeral D in FIG. 10 / the engaging portion between the upper lid and the inner container body is viewed from diagonally below inside the container). It is a figure which shows. FIG. 12 is a conceptual diagram showing an example of a forest burial ground. FIG. 13 is a perspective view showing another configuration example of the forest burial container according to the embodiment.

As shown in FIGS. 1 to 11, the forest burial container 11 according to the embodiment of the present invention is housed in the outer container 12 so as to be stacked vertically with the outer container 12 having a cylindrical overall shape. It is composed of two inner containers 21 and 31.

The outer container 11 is composed of a vertically erecting cylindrical peripheral wall (outer peripheral wall) 14 and a bottom lid (outer bottom lid) 15 that closes the bottom surface of a cylindrical storage space 17 surrounded by the peripheral wall 14. It has a container main body 13 and an outer lid 18 that closes the top surface opening (outer container opening) 15 of the outer container main body 13 so as to be openable and closable. The peripheral wall 14 of the outer container main body 13 can be formed by using a general-purpose resin pipe (for example, ABS resin pipe, vinyl chloride pipe, etc.), and the resin pipe is cut to a predetermined length and formed at the lower end. The bottom lid 15 may be fixed to close the bottom surface of the peripheral wall 14. The bottom lid 15 may be fixed by a method such as welding or adhesion with an adhesive. Further, the other parts of the outer container 12 (bottom lid 15 and outer lid 18) are also made of a resin material.

Further, a locking groove 16 (outer lid locking groove) for locking the outer lid 18 to the peripheral wall 14 is formed on the outer peripheral surface of the upper end portion of the outer container main body 13 (peripheral wall 14). The locking groove 16 constitutes an outer lid locking means for detachably fixing the outer lid 18 to the outer container main body 13 together with a locking projection 19 described later. In the present embodiment, the outer lid locking means , That is, two sets of locking grooves 16 and locking projections 19 are provided. Further, these two outer lid locking means are arranged at both ends of the diameter of the cylindrical peripheral wall 14 (positions symmetrical with respect to the central axis of the peripheral wall 14). This is to stably fix the outer lid 18 to the peripheral wall 14.

Each locking groove 16 includes a vertical groove portion (outer container vertical groove portion) 16a extending vertically downward from the upper edge of the outer surface of the peripheral wall 14, and a horizontal groove portion extending horizontally along the outer surface of the peripheral wall 14 continuously from the lower end of the vertical groove portion 16a. It is composed of (outer container horizontal groove portion) 16b and has an L-shaped overall shape. Further, the horizontal groove portion 16b enables opening and closing of the outer lid 18 (engagement and disengagement of both locking projections 19 and 19 on both horizontal groove portions 16b and 16b), so that the outer peripheral surface of the peripheral wall 14 is formed from the lower end of the vertical groove portion 16a. (In the case of this embodiment, the outer container body 13 is formed so as to extend counterclockwise from the lower end of the vertical groove portion 16a when viewed from above). The horizontal groove portion 16b may be formed so as to extend clockwise, contrary to the illustrated example.

On the other hand, the outer lid 18 has a disk-shaped top plate (outer lid top plate) 18a capable of covering the outer container opening 15 and the outer container main body 13 that descends vertically downward from the peripheral edge of the outer lid top plate 18a. It is composed of a ring-shaped side wall (outer lid side wall) 18b into which the upper end portion (outer lid fitting portion) 20 of the (peripheral wall 14) can be fitted. The inner surface of the side wall 18b is provided with a locking projection (outer lid locking projection) 19 that fits into the outer lid locking groove 16. The locking projection 19 is a columnar protrusion having an outer diameter smaller than the groove width of the locking groove 16, and projects horizontally from the inner surface of the side wall 18b toward the center of the outer container opening 15. Further, two locking projections 19 are provided according to the number of locking grooves 16.

To attach the outer lid 18 to the outer container body 13, cover the outer lid 18 on the upper surface of the outer container body 13 so that the locking projection 19 is aligned with the engaging groove 16 (vertical groove 16a), and the locking projection 19 is attached. Is fitted into the vertical groove portion 16a of the engaging groove 16 (see arrow F1 in FIGS. 3 and 5), and after advancing to the lower end of the vertical groove portion 16a (see reference numeral 19a in FIG. 5), the outer lid 18 is viewed from above. By turning it counterclockwise, the locking projection may reach the tip of the horizontal groove (see arrows F2 and reference numeral 19b in FIGS. 3 and 5). In this state, since the locking projection 19 is caught on the upper surface of the horizontal groove portion 16b, the outer lid 18 does not open (the outer lid 18 does not come off from the outer container main body 13 upward). To open the outer lid 18, turn the outer lid 18 in the opposite direction (clockwise), arrange the locking projection 19 at the base end of the horizontal groove 16b (lower end of the vertical groove 16a), and then open the outer lid. 18 should be removed upward.

The shape of the outer container 12 is assumed to have a vertically long overall shape, for example, a height H1 (see FIG. 1) having a diameter D1 or more three times or more. This is so that the inner containers 21 and 31 can be stacked and stored in the vertical direction, and the remains of a plurality of persons (plurality of inner containers) can be stored and buried in the outer container 12. The specific dimensional value is not particularly limited, but for example, the diameter D1 can be, for example, about 20 to 25 cm, and the height H1 can be, for example, about 800 to 850 cm.

On the other hand, the inner containers 21 and 31 have a cylindrical inner container body 22 having an opening on the upper surface and capable of accommodating ashes inside, and an upper surface opening (inner container opening) 22a that can be opened and closed. Each has an upper lid 23. The outer diameter of the inner containers 21 and 31 is slightly smaller than the inner diameter of the outer container 12 (peripheral wall 14) so that the inner containers 21 and 31 can be stored in the storage space 17 of the outer container 12. Further, the inner containers 21 and 31 have a tapered peripheral surface whose bottom surface is smaller than the top surface and whose horizontal cross-sectional area gradually decreases from the top surface toward the bottom surface. If the peripheral surfaces of the inner containers 21 and 31 are tapered in this way, the inner containers 21 and 31 can be easily inserted into the upper surface opening 15 of the outer container 12, and the inner containers 21 and 31 can be easily inserted into the storage space 17 of the outer container 12. Will be able to be stored smoothly.

The inner containers 21 and 31 are formed of a resin material (for example, ABS resin, polyvinyl chloride, etc.) like the outer container 12. By making it made of resin, it is possible to manufacture a burial container that is strong against impact at a low cost, and it is possible to incinerate, dissolve, and recycle it, so that it can be easily disposed of. Further, as described above, even in the event of a large-scale disaster such as an earthquake, the ashes can be protected by the double structure of the resin container (outer container 12 and inner container 21, 31) which is hard to be damaged. By engraving the names of the mourner and the deceased on the vessels 21 and 31, it is possible to immediately identify who the remains are and prevent the occurrence of unnamed bones.

The inner container main body 22 and the upper lid 23 are provided with a locking mechanism for fixing the upper lid 23 to the upper surface portion of the inner container main body 22 and a latch mechanism for preventing the upper lid 23 from loosening. Hereinafter, these will be described with reference to FIGS. 10 to 11.

The upper lid 23 includes a disk-shaped top plate 23a that covers the upper surface opening 22a of the inner container main body 22 and a ring-shaped side wall 23b that rises from the peripheral edge of the top plate 23a, and a plurality of upper lids 23 are provided on the inner peripheral surface of the side wall 23b. In the case of the form, it has four locking grooves (upper lid locking grooves) 26. Each of these locking grooves 26 includes a vertical groove portion 26a extending vertically upward from the lower end of the side wall 23b and a horizontal groove portion 26b extending horizontally along the side wall 23b from the upper end of the vertical groove portion 26a, and has an L-shape as a whole. Has a shape.

On the other hand, the inner container main body 22 is provided with a ring-shaped upper lid fitting portion 24 that can be fitted just inside the side wall 23b of the upper lid 23 at the upper end portion thereof, and the upper lid fitting portion 24 is provided with the upper lid 23. An upper lid locking projection 25 (four in the case of this embodiment, corresponding to the number of locking grooves 26) is provided corresponding to each locking groove 26.

Further, as a latch mechanism for preventing the upper lid 23 from loosening, a recess 25a is provided at the tip of each locking projection 25, and a convex portion 26c that fits with the recess 25a is provided at the tip of each locking groove 26.

When the upper lid 23 is put on the upper lid fitting portion 24 at the upper end of the inner container body (see arrow F3), each locking projection 25 enters the vertical groove portion 26a of each corresponding locking groove 26, respectively, and the upper lid 23 As the push-down operation is performed downward, the vertical groove portion 26a moves upward relative to each other (see arrow F5 in FIG. 11). After that, when the upper lid 23 is rotated (see arrow F4), each of the locking projections 25 moves further horizontally in each of the horizontal groove portions 26b continuous with the vertical groove portion 26a in each of the corresponding locking grooves 26 (FIG. 11), the convex portion 26c formed at the tip of the locking groove 26 fits into the concave portion 25a formed at the tip of the locking projection 25. As a result, the upper lid 23 is fixed to the inner container main body 22, and in this closed state, the latch mechanism (recessed portion 25a and convex portion 26c) prevents the upper lid 23 from loosening (relative rotation of the upper lid 23 and the inner container main body 22). The internal space of the inner container body 22 that houses the ashes is kept in a closed state.

FIG. 12 shows an example of a forest burial graveyard where the forest burial container 11 of the present embodiment can be used. As shown in this figure, burial can be performed by burying the container 11 of the present embodiment in the ground under each disk-shaped tombstone 30. The shape and presence of the tombstone 30, the shape and arrangement of the burial area, the arrangement of trees, and the like are various, and are not limited to the illustrated examples.

Although the embodiments of the present invention have been described above, it is clear to those skilled in the art that the present invention is not limited to these and various changes can be made within the scope of the utility model registration claims. Is.

For example, although the two inner containers 21 and 31 are provided in the above embodiment, as shown in FIG. 13, the three inner containers 21, 31 and 41 may be stored in the outer container 12. Further, by setting the height H1 of the outer container 12 and the heights H2 to H4 of the inner containers 21, 31 and 41 in various ways, a structure is provided in which four or more inner containers are stored in the outer container 12. Is also possible.
