Claims

[Scope of Claim for Utility Model Registration] 1. A decompression case provided with a depressurizing means for reducing the pressure in the internal space and a pressure increasing means for increasing the pressure from the depressurized state, and a depressurizing case provided within the depressurizing case. A powder supply nozzle inserted into the filling port of a container disposed inside the container, a powder supply device capable of supplying a predetermined amount of powder to the powder supply nozzle, and a powder supply nozzle disposed inside the vacuum case. and a container lifting/lowering means for lifting and lowering the container so that the container can be freely switched between a state in which the filling opening of the container is inserted into a nozzle portion formed at the tip of a powder supply nozzle and a state in which the nozzle portion is removed from the filling opening of the container. 1. A powder filling device comprising: a powder scraping portion whose tip can be brought into sliding contact with the outer periphery of the nozzle portion on the inner surface of the filling opening of the container. 2. A tapered surface is formed on the upper surface of the powder scraping part to guide the nozzle part to an insertion opening formed in the powder scraping part, and the powder supply nozzle has
The powder filling device according to claim 1, further comprising a tapered surface that can come into contact with the tapered surface of the powder scraping section. 3 A decompression case equipped with a depressurizing means for reducing the pressure in the internal space and a pressure increasing means for increasing the pressure from this depressurized state, and a container provided within the depressurizing case and disposed within the depressurizing case. A powder supply nozzle inserted into the filling port, a powder supply device capable of supplying a predetermined amount of powder to the powder supply nozzle, and an expansion member provided around the powder supply nozzle, A filling port closing means that can switch between a state in which a gap is formed with the filling port of the container and a state in which the gap is closed by changing the outer diameter of the expansion member. Body filling device.
