Abstract
Description
[Technical Field]
[0001] This invention relates to ceramic dummy coins. [Background technology]
[0002] Traditionally, when a person is cremated, grave goods are often placed in the coffin along with the body.
[0003] Grave goods generally include flammable items such as fresh flowers and letters, which are incinerated along with the body and turned to ashes, so there is no problem in collecting the remains. [Prior art documents] [Patent documents]
[0004] Mito 3083531 Summary of the Invention [Problem to be solved by the invention]
[0005] In some regions, it is customary to place coins in the coffin during cremation. These coins are considered necessary for the deceased as a fare for crossing the Sanzu River. Coins placed in the coffin melt in the heat of the crematorium and stick to the cremation cart and remains, tainting the remains and damaging the cremation cart and crematorium equipment. Coins primarily composed of copper, such as 10-yen coins, are known to discolor the remains when melted in the heat of the crematorium, significantly damaging the funeral sentiments of the bereaved. Eliminating this risk of discoloration of remains is also an essential challenge. Furthermore, the current practice of melting currency violates the Coin Damage Control Act. A legal method is needed that respects the bereaved's desire to send the deceased off peacefully while avoiding tainting the remains and damaging crematorium equipment. Currently, paper with a picture of the Kan'ei Tsūhō coin printed on it or pieces of wood carved into the shape of a coin are sometimes used as substitutes for coins, but these are too conventional as ceremonial items and are not suitable for sending off the deceased. [Means for solving the problem]
[0006] The invention described in claim 1 is a ceremonial dummy coin made of non-flammable ceramic in the shape of a Kan'ei Tsuho one-sen coin, a currency from the Edo period. [Effects of the Invention]
[0007] By using this device during cremation, it is possible to carry out a legal cremation that satisfies the funeral sentiment without soiling the remains or damaging the crematorium facilities. By combining the standardized Kan'ei Tsūhō shape with precision ceramic molding technology, it is possible to achieve both an exquisite texture similar to the real thing and inexpensive mass production, enabling a stable supply of high-quality ritual items to the nationwide funeral market.
[0008] The melting point of alumina, a typical ceramic, is approximately 2050°C, but it does not melt at the maximum temperature of a crematorium furnace, which is 1200°C. This device remains intact after cremation, so the bereaved can collect the ashes and store them in an urn. This ensures that the deceased receives the funeral fee, increasing the spiritual satisfaction of the bereaved. [Brief explanation of the drawings]

Claims
[Claim 1] This ceremonial dummy coin is made of ceramic, which does not melt even at the maximum crematorium temperature of 1,200 degrees, leaves no harmful residue in the furnace, and does not discolor the remains.It is shaped to resemble the Kan'ei Tsūhō coin to serve as a ferry fare equivalent to a six-mon coin.
