2. Description of the Related Art A spray container in which a liquid for spraying and a liquefied gas are contained in a container and the liquid for spraying is jetted (sprayed) by the vaporized gas pressure of the liquefied gas has been conventionally used for hairdressing agents and the like. It has been widely used as a container for medicines such as lotion and pesticide, and paints such as paint.

Most spray containers use a flammable gas such as liquefied propane or liquefied butane as a liquefied gas for spraying, and some flammable gas may remain in the container after the spray container is used.

The spray container after use is normally disposed of as incombustible waste, but if it is accidentally thrown into a fire together with combustible waste, the residual gas in the container may catch fire and explode. . In order to prevent such an accident, it is necessary to make a hole in the container with a nail or the like to release gas, but it takes time and effort to make a hole, so most of the used spray containers are not exhausted and are discarded as they are. There is.

Further, the container body of the spray container is often made of metal such as aluminum or tin plate and can be collected and reused as resource waste. However, the spray valve mechanism and nozzle body are made of synthetic resin. Most of them are made of wood,
It cannot be reused without removing the valve mechanism and nozzle body from the container body. However, since the liquefied gas is stored in the spray container at a high pressure, it has a structure that cannot be easily disassembled so as to withstand this high pressure, and the valve mechanism and nozzle body are not removed from the container body even after use. It was not easy to remove.
