  However, in the storage tank in the hopper described in Patent Document 1 and the storage tank 14 described above, the area of the supply port is larger than the area of the discharge port in order to facilitate the supply of powder. There is a problem in that the amount of powder falling through the outlet differs depending on the part of the discharge port and is difficult to be uniform. Therefore, the amount of the powder filled in the container is also different for each part of the discharge port, and it is difficult to be uniform, and as a result, the quality of the product is deteriorated.

  This is because the powder falls from the hopper by its own weight, so if the area of the supply port is larger than the area of the discharge port, the amount of powder stored in the storage tank tends to vary from site to site of the discharge port. This is because the force to drop the powder through the discharge port is likely to vary from site to site of the discharge port.

  For example, in the case of the storage tank in the hopper described in Patent Document 1, since the cross-sectional area is reduced from the supply port toward the discharge port, the amount of powder is the center of the discharge port. And the periphery of the discharge port. Moreover, in the case of the storage tank 14, since cosmetic C2 is supplied to the dish-shaped part 15 in a mountain shape, the quantity of cosmetic C2 will differ for every site | part of the discharge outlet 16. FIG.

  An object of the present invention is to provide a powder filling apparatus that can make the amount of powder falling through the discharge port uniform and thus improve the quality of the product.

A powder filling apparatus according to a first aspect of the present invention is a powder filling apparatus that includes a hopper having a storage tank for storing powder therein, and drops the powder from the hopper and fills the container. A supply port formed on the vertically upper side for supplying the powder to the inside; and a container opening on the vertically lower side for discharging the powder; and formed so as to be directly connected to the container opening. A discharge port having a smaller area than the supply port, and a cylindrical body having the same cross-sectional shape as the discharge port from one end to the other end. The cylindrical body is stored via the supply port. Inserted inside the tank and attached to one end connected to the discharge port, the powder is not supplied from the supply port to the inside of the storage tank, but from the other end of the cylindrical body to the inside of the storage tank. It is characterized by supplying.

According to such a configuration, the cylindrical body is inserted into the storage tank through the supply port, and one end of the cylindrical body is connected to the discharge port. By supplying the powder from the other end of the body, the powder can be dropped from the hopper and filled into the container.

Can be stored inside the cylindrical body. Accordingly, since the amount of powder per unit area can be increased, the force for dropping the powder through the discharge port is increased, and the powder can be more stably filled into the container. . Therefore, according to the present invention, the quality of the product can be further improved.

A powder filling device according to a second aspect of the present invention is a powder filling device that includes a hopper having a storage tank for storing powder therein, and drops the powder from the hopper and fills the container. A supply port formed on the vertically upper side for supplying the powder to the inside; and a container opening on the vertically lower side for discharging the powder; and formed so as to be directly connected to the container opening. The discharge port is formed in a cylindrical shape having the same cross-sectional shape from the supply port to the discharge port.

  According to such a configuration, since the storage tank is formed in a cylindrical shape having the same cross-sectional shape from the supply port to the discharge port, the amount of the powder stored in the storage tank is different for each part of the discharge port. Therefore, the force to drop the powder through the discharge port is also difficult to vary for each part of the discharge port. Therefore, according to the present invention, it is possible to make the amount of the powder falling through the discharge port uniform, and to improve the quality of the product.

  In the second invention, the storage tank is preferably formed in a cylindrical shape, and the length from the discharge port to the supply port is preferably longer than the inner diameter of the discharge port.

  According to such a configuration, since the length from the discharge port to the supply port is longer than the inner diameter of the discharge port, more powder is stored in the storage tank than in the case where the length is shorter than the inner diameter of the discharge port. Can be stored inside. Accordingly, since the amount of powder per unit area can be increased, the force for dropping the powder through the discharge port is increased, and the powder can be more stably filled into the container. . Therefore, according to the present invention, the quality of the product can be further improved.
