Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a cartridge-type stick-shaped cosmetic container.

[Conventional technology]

Conventionally, a holding cylinder that fits and holds a stick-shaped cosmetic material, and a guide cylinder that makes the holding cylinder non-rotatable but vertically slidable,
A spiral tube into which the holding tube is screwed, and a sleeve that covers the stick-shaped cosmetic material and the structure such as the holding tube and the guide tube are the main constituent elements, and the lower end surface is provided with an engaging hole. Consists of a cartridge that has been bored and a holder that protrudes from the engagement hole of the cartridge and is rotatably installed in the cartridge, for example, a holder in which the engagement body that engages with a guide cylinder or a spiral cylinder is erected on the bottom Many cartridge type stick-shaped cosmetic material feeding containers have been proposed. This kind of structure can provide a cartridge type container having a simple structure.

Further, in this kind of feeding container, a spiral cylinder made by winding a thin metal material was used for the purpose of forming a slender outer diameter.

[Problems to be solved by the device]

The engaging body of this holder is rush-engaged with the lower part of the structure that is rotatably installed in the cartridge, so if the structure and the engaging body are engaged too strongly, the structure will not be removed when the cartridge is removed. There was a risk that the cartridge would fall out, and the engagement between the cartridge and the holder could not be made too strong. As a result, the turning torque could not be properly transmitted to the structure during the turning operation, and the operation feeling deteriorated. In addition, the cartridge was sometimes accidentally dropped from the holder.

In addition, the feel of the feeding operation is also different because abnormal friction occurs due to burrs generated at the end of the spiral cylinder and the spiral groove during sliding contact when the spiral cylinder made of metal rotates with the resin cylinder. I often felt a sense of harmony.

It is also proposed to form a special coating of resin paint on the inner surface of the spiral cylinder. However, in this spiral cylinder, resin paint is likely to accumulate and it is difficult to finish the inner diameter uniformly, and although a strange feeling due to burrs can be solved, it is not possible to obtain a smooth rotational feeding feeling.
