Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the above-mentioned funeral implement for cremation is premised on not being deformed or melted during cremation and remaining unburned. Therefore, after cremation, only the same kind of thing remains unburned every time, and it does not become a memento with the respective feelings of the deceased pet or person incorporated.

[0005] The present invention provides a method for manufacturing a memento in which mementos having different shapes with the respective feelings of a deceased pet or the like incorporated therein can be obtained.

Means for Solving the Problems

[0006] One aspect of the method for manufacturing a keepsake according to the present invention includes a pre-cremation step of accommodating a cremation object, which is a pet or a human, and a keepsake material made of glass in a cremation furnace, and a cremation step of cremating the cremation object in the cremation furnace and deforming the keepsake material to produce a keepsake. The melting temperature of the keepsake material is lower than the cremation temperature at which the cremation object is cremated in the cremation step.

[0007] According to the above method for manufacturing a keepsake, in the cremation step, a cremation object such as a pet is cremated together with a keepsake material made of glass. Therefore, it is possible to cremate a cremation object such as a pet and produce a keepsake by melting, cooling, and deforming the keepsake material. As a result, a keepsake filled with the feelings of a deceased pet or the like can be obtained.

[0008] Furthermore, in the cremation step, the atmosphere, temperature, etc. inside the cremation furnace during cremation vary depending on the cremation object such as a pet being cremated. Therefore, it is possible to produce keepsakes deformed into different shapes each time. As a result, a unique keepsake for a deceased pet or the like can be obtained. And that keepsake will have an even stronger sense of the feelings of the deceased pet or the like.

[0009] In the above method for manufacturing a keepsake, the keepsake material may be spherical. In this case, in the cremation step, cracks, chips, etc. are less likely to occur in the keepsake obtained by melting, cooling, and deforming the keepsake material.

[0010] Also, the cremation temperature may be 1000°C or lower. In this case, by preventing the difference between the melting temperature of the glass constituting the keepsake material and the cremation temperature from becoming large, cracks, chips, etc. are less likely to occur in the keepsake obtained by melting, cooling, and deforming the keepsake material in the cremation step.

[0011] In addition, in the pre-cremation process, the memento material may be placed on an adhesion inhibitor that suppresses adhesion to the memento produced in the cremation process. In this case, in the cremation process, the memento material is melted and cooled on the adhesion inhibitor to be deformed, so that a memento can be produced without adhering to the adhesion inhibitor. In addition, the produced memento can be easily taken out from above the adhesion inhibitor, and a memento excellent in appearance, quality, etc. can be obtained.

[0012] In addition, the adhesion inhibitor may be a sheet material composed of ceramic fibers. In this case, in the cremation process, it becomes easy to melt and cool the memento material on the sheet material to be deformed. In addition, the produced memento can be easily taken out from above the sheet material.

[0013] In addition, the adhesion inhibitor may be a biscuit material obtained by biscuit-firing clay. In this case, in the cremation process, it becomes easy to melt and cool the memento material on the biscuit material to be deformed. In addition, the produced memento can be easily taken out from above the biscuit material.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described. (First Embodiment) The method for manufacturing a keepsake of this embodiment is a method for producing a keepsake of a pet to be cremated during the process of cremating a deceased pet.

[0016] The method for manufacturing a keepsake includes a pre-cremation process and a cremation process. In the pre-cremation process, as shown in FIGS. 1 and 2, an object to be cremated 1 and a keepsake material 2 are placed in a cremation furnace. The object to be cremated 1 is a deceased pet (the body of the pet). In this embodiment, an example of a dog is shown as the pet. Although not shown in the drawings, the cremation furnace is a facility for cremating the object to be cremated 1. As the cremation furnace, various conventionally known cremation furnaces can be used.

[0017] The cremation furnace has a cremation platform 31 made of refractory concrete. The cremation platform 31 can be carried into the cremation furnace using a trolley. The cremation platform 31 has a recess 311 in the central portion. A ceramic fiber sheet 32 with a thickness of 12.5 mm is provided on the upper surface and the inner wall surface of the recess 311. Also, a plurality of refractory bricks 33 are provided in the recess 311.

[0018] On top of the plurality of refractory bricks 33, a wire mesh 34 with a thickness of 20 mm is provided. On top of the wire mesh 34, a ceramic fiber sheet 35 with a thickness of 12.5 mm is provided. On top of the ceramic fiber sheet 35, a wire mesh 36 with a thickness of 5 mm is provided. On top of the wire mesh 36, a non-woven fabric 37 is provided so as to cover the wire mesh 36.

[0019] On top of the non-woven fabric 37, the cremation object 1 is placed. Also, on top of the non-woven fabric 37, the memento material 2 is arranged. At this time, the memento material 2 is arranged on top of the adhesion inhibitor 4. That is, the adhesion inhibitor 4 is arranged on top of the non-woven fabric 37, and the memento material 2 is arranged on top of the adhesion inhibitor 4. The memento material 2 and the adhesion inhibitor 4 will be described later.

[0020] On the non-woven fabric 37, the memento material 2 is arranged beside the cremation object 1. The memento material 2 is arranged in the area A (the area on the opposite side of the back or the area far from the back) on the lower side or the front side of the dog which is the cremation object 1. This is to prevent the memento material 2 from coming into contact with the dog's back when the dog which is the cremation object 1 is cremated due to the dog's back warping.

[0021] As shown in FIGS. 3 and 4, the memento material 2 is arranged on top of the adhesion inhibitor 4. The memento material 2 is ultimately the memento of the pet and is composed of glass. The memento material 2 is a spherical glass ball. In this embodiment, a glass ball with a diameter of 12.5 mm is used as the memento material 2. Note that the size of the memento material 2 can be changed as appropriate.

[0022] The material of the memento material 2 is silicate glass mainly composed of silicon dioxide (silica: SiO2). The melting temperature (melting point) of the memento material 2 is lower than the cremation temperature (for example, 850°C to 1000°C) at which the cremation object 1 is cremated in the cremation process described later. The melting temperature of the memento material 2 is 700 - 800°C.

[0023] The adhesion suppression material 4 is a sheet material composed of ceramic fibers. The ceramic fibers are inorganic fibers mainly composed of alumina (Al2O3) and silica (SiO2). In this embodiment, a ceramic fiber sheet with a length of 40 mm, a width of 40 mm, and a thickness of 6 mm is used as the adhesion suppression material 4. The adhesion suppression material 4 serves as a location for melting and cooling the memento material 2 in the cremation process described later, and suppresses adhesion to the produced memento.

[0024] In the pre-cremation process, as described above, the cremation platform 31 on which the cremation object 1 and the memento material 2 are arranged is carried into the cremation furnace using a cart. Thereby, the cremation object 1 and the memento material 2 are accommodated in the cremation furnace.

[0025] Next, in the cremation process, in the cremation furnace, the cremation object 1 is cremated and the memento material 2 is deformed to produce a memento. The cremation process is divided into a temperature rising process, this cremation process, and a temperature lowering process. The temperature rising process raises the temperature in the cremation furnace from room temperature to the cremation temperature. This cremation process maintains the temperature in the cremation furnace at the cremation temperature and burns the cremation object 1. The temperature lowering process lowers the temperature in the cremation furnace from the cremation temperature.

[0026] Specifically, in the temperature rising process, the temperature in the cremation furnace is raised from room temperature to the cremation temperature in about 7 to 8 minutes by a burner provided in the cremation furnace. The cremation temperature can be, for example, 850°C to 1000°C. In this embodiment, by setting the cremation temperature to 1000°C or lower, the difference between the melting temperature of the memento material 2 and the cremation temperature is prevented from becoming large.

[0027] Next, in this cremation process, the temperature in the cremation furnace is maintained at the cremation temperature and the cremation object 1 is burned. The time for maintaining the cremation temperature (cremation time) can be adjusted according to the size of the cremation object 1 and the like. The cremation time can be, for example, 15 to 120 minutes.

[0028] At this time, the temperature in the cremation furnace (cremation temperature) is higher than the melting temperature of the memento material 2. Therefore, the spherical and solid memento material 2 arranged on the adhesion suppression material 4 melts and becomes a liquid (molten state).

[0029] Next, in the temperature reduction process, the temperature inside the cremation furnace is reduced from the cremation temperature to around 300°C in about 5 minutes. Then, it is reduced to around 100°C in 10 - 15 minutes. In this process, the molten memento material 2 on the adhesion suppression material 4 is cooled and solidified. As a result, as shown in FIG. 5, the memento 21 that is greatly deformed from the spherical memento material 2 is obtained.

[0030] After that, the cremation platform 31 is carried out of the cremation furnace using a cart. Then, the produced memento 21 is taken out from above the adhesion suppression material 4. Here, the adhesion suppression material 4 suppresses adhesion to the produced memento 21. Therefore, the memento 21 can be easily taken out from above the material of the adhesion suppression material 4.

[0031] Next, the effects of the method for manufacturing the memento in the present embodiment will be described. According to the method for manufacturing the memento in the present embodiment, in the cremation process, the cremation object 1, which is a deceased pet, is cremated together with the memento material 2 made of glass. Therefore, while cremating the cremation object 1, the memento 21 obtained by melting, cooling, and deforming the memento material 2 can be produced. As a result, the memento 21 is formed beside the deceased pet and contains the thoughts of the deceased pet.

[0032] Furthermore, in the cremation process, the atmosphere, temperature, etc. inside the cremation furnace during cremation vary depending on the cremation object 1 to be cremated. That is, the gases generated during cremation and the temperature changes during cremation vary depending on the cremation object 1. Therefore, mementos deformed into different shapes can be produced each time. As a result, a unique memento 21 for the deceased pet is obtained. And the memento 21 has even stronger thoughts of the deceased pet.

[0033] In the method for manufacturing the memento in the present embodiment, the memento material 2 is spherical. Therefore, in the cremation process, cracks, chips, etc. are less likely to occur in the memento 21 obtained by melting, cooling, and deforming the memento material 2.

[0034] Further, the cremation temperature is 1000°C or lower. Therefore, the difference between the melting temperature of the glass constituting the memento material 2 and the cremation temperature can be prevented from becoming large. As a result, in the cremation process, cracks, chips, etc. are less likely to occur in the memento 21 obtained by melting, cooling, and deforming the memento material 2.

[0035] Also, in the pre-cremation process, the memento material 2 is placed on the adhesion inhibitor 4 that suppresses adhesion to the memento 21 produced in the cremation process. Therefore, in the cremation process, by melting, cooling, and deforming the memento material 2 on the adhesion inhibitor 4, the memento 21 can be produced without adhering to the adhesion inhibitor 4. Further, the produced memento 21 can be easily taken out from above the adhesion inhibitor 4, and a memento 21 excellent in appearance, quality, etc. can be obtained.

[0036] Also, the adhesion inhibitor 4 is a sheet material (ceramic fiber sheet) composed of ceramic fibers. Therefore, in the cremation process, it becomes easy to melt, cool, and deform the memento material 2 on the sheet material that is the adhesion inhibitor 4. Further, the produced memento 21 can be easily taken out from above the sheet material that is the adhesion inhibitor 4.

[0037] (Second Embodiment) As shown in FIGS. 6 and 7, this embodiment is an example in which the configuration of arranging the memento material 2 on the adhesion inhibitor 4 is changed. Note that the description of the same configuration, operation, and effects as those of the first embodiment will be omitted.

[0038] As shown in FIG. 6, in addition to the adhesion inhibitor 4 on which the memento material 2 is arranged, an annular frame 5 is prepared. The frame 5 is made of iron. The material of the frame 5 may be any material having heat resistance, fire resistance, etc.

[0039] As shown in FIG. 7, in the pre-cremation process, the frame body 5 is arranged under the adhesion inhibitor 4. That is, the adhesion inhibitor 4 is arranged so as to cover the frame body 5. Thereby, a concave portion 41 formed by the adhesion inhibitor 4 is provided inside the frame body 5. Then, the memento material 2 is arranged in the concave portion 41 of the adhesion inhibitor 4.

[0040] In the present embodiment, in the cremation process, the memento material 2 can be melted, cooled, and deformed in the concave portion 41 of the adhesion inhibitor 4. In particular, when the memento material 2 is in a molten state, it can be suppressed from flowing out to the outside of the adhesion inhibitor 4. Thereby, the memento 21 can be reliably produced on the adhesion inhibitor 4.

[0041] (Third Embodiment) As shown in FIGS. 8 and 9, the present embodiment is an example in which the material of the adhesion inhibitor for arranging the memento material 2 is changed. Note that the description of the same configuration, operation, and effects as those of the first embodiment will be omitted.

[0042] As shown in FIG. 8, the adhesion inhibitor 6 is a bisque material obtained by bisque-firing clay. As the clay used as the raw material of the bisque material, for example, pottery clay, clay for clay pot (clay containing petalite), etc. can be used. Bisque-firing means lightly firing at a relatively low temperature (for example, 700 to 800 ° C) without applying glaze in order to remove the moisture contained in the base of the clay.

[0043] The adhesion inhibitor 6 is configured in a rectangular plate shape. In the present embodiment, a bisque material having a length of 40 mm, a width of 40 mm, and a thickness of 10 mm is used as the adhesion inhibitor 6. The adhesion inhibitor 6 has a concave portion 61 in the central portion. The concave portion 61 of the adhesion inhibitor 6 is a place where the memento material 2 is melted and cooled in the cremation process.

[0044] As shown in FIG. 9, in the pre-cremation process, the memento material 2 is arranged in the concave portion 61 of the adhesion inhibitor 6. Then, in the cremation process, the memento material 2 can be melted, cooled, and deformed in the concave portion 61 of the adhesion inhibitor 6. In particular, when the memento material 2 is in a molten state, it can be suppressed from flowing out to the outside of the adhesion inhibitor 6.

[0045] In this embodiment, the adhesion inhibitor 6 is a bisque material obtained by bisque-firing clay. Therefore, in the cremation process, it becomes easy to melt, cool, and deform the memento material 2 on the bisque material which is the adhesion inhibitor 6. Also, the produced memento 21 can be easily taken out from above the bisque material which is the adhesion inhibitor 6. Further, when using pottery or porcelain obtained by glaze-firing clay, there is a risk of cracking in the cremation process, but such cracking does not occur in the bisque material, so the memento material 2 can be melted, cooled, and deformed, and the memento 21 can be produced easily and surely. Note that glaze-firing means firing clay coated with glaze at a temperature higher than that of bisque-firing (for example, 1200 °C or higher).

[0046] (Other embodiments) The present invention is not limited to the above-described embodiment at all, and it goes without saying that the present invention can be implemented in various modes without departing from the scope of the present invention.

[0047] (1) In the above embodiment, the cremation object 1 was a pet, but the cremation object may be a human. Also, although an example of a dog was shown as the pet which is the cremation object 1, the pet is an animal or the like kept by a person, and for example, it may be a dog, a cat, small animals (such as rabbits, mice, birds, etc.), insects, etc.

[0048] (2) In the above embodiment, as the material constituting the memento material 2, a silicate glass mainly composed of silicon dioxide (SiO2) was used, but it may be configured using various other glass materials.

[0049] (3) In the above embodiment, the memento material 2 is spherical, but the shape of the memento material may be other shapes than spherical.

[0050] (4) In the above-described embodiment, the bead ball with a diameter of 12.5 mm was used as the memento material 2, but the size of the memento material 2 may be changed according to the cremation time of the cremation target 1 or the like. For example, when the cremation time is 40 minutes or less, a bead ball with a diameter of 12.5 mm may be used, and when the cremation time exceeds 40 minutes, a bead ball with a diameter of 17 mm may be used.

[0051] (5) In the above-described embodiment, the recess 41 was formed in the adhesion inhibitor 4 using the frame body 5, but a recess may be formed in the adhesion inhibitor (sheet material) using other members, or the recess may be formed, for example, by denting without using members or the like.

[0052] (6) The functions of one component in the above-described embodiment may be dispersed as a plurality of components, or the functions of a plurality of components may be integrated into one component. Also, a part of the configuration of the above-described embodiment may be omitted. Further, at least a part of the configuration of the above-described embodiment may be added to, replaced with, etc. the configuration of other above-described embodiments. Note that all aspects included in the technical idea specified from the language described in the claims are embodiments of the present invention.
