Mortuary cooling device for coffin : Patent

■License transfer and usage permission for body cooling equipment for coffins

Patent summary: “Corporal storage cooling device” that does not use dry ice, which is carbon dioxide itself.

Patent content: This is a proposal for a new type of coffin that maintains the temperature inside the coffin at 5℃ and wraps the entire Buddha in gentle cool air.

By not using dry ice (-78.9℃), there is no environmental problem such as air pollution, and by using a household power source, we have achieved energy savings and low costs.


・We will prevent the body from freezing at a lower temperature than necessary and consider the feelings of the bereaved family.

  • Even when dry ice melts, it does not become a liquid; it directly returns to gaseous carbon dioxide and diffuses into the atmosphere.
    ・When dry ice vaporizes, it emits a large amount of CO2.


・Bacteria that cause decomposition of corpses
・Pathogen organisms attached to the corpse
・Chemical changes caused by enzymes generated from the corpse

Regarding the control of these activities, decomposition of the body will be stopped by lowering the temperature below 5℃.
We have developed a temperature setting that takes these into account.
