DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-shaped cosmetic cartridge, and more particularly, to a stick-shaped cosmetic cartridge capable of accommodating a stick-shaped cosmetic such as lipstick and gradually projecting the same.

[0002]

2. Description of the Related Art In many cases, stick cosmetics such as lip liners, lipsticks, concealers and eyeliners are usually stored in containers, and are drawn out of containers only when used to expose them. After use, pull it back into the container and store it.

[0003] The stick-shaped cosmetic dispensing container of the above-mentioned method of use cannot be replaced with a stick-shaped cosmetic, so when the stick-shaped cosmetic is used up, the container must be discarded. Therefore, in order to effectively use the stick-shaped cosmetic material feeding container, a type in which the stick-shaped cosmetic material can be replaced is disclosed in Japanese Utility Model Publication No. 3-31232.

In this case, a stick-shaped cosmetic cartridge (hereinafter, referred to as a “cartridge”) is detachably mounted on an outer cylinder. A push rod is stored inside the outer cylinder. When the mounted cartridge is rotated with respect to the outer cylinder, the push rod is configured to move inside the outer cylinder in the axial direction. The cartridge includes a storage cylinder, and the storage cylinder is provided with a through hole penetrating in the axial direction.

That is, a small-diameter hole having a diameter slightly larger than the outer diameter of the cosmetic is provided at the distal end of the through-hole, and the cross-sectional shape is substantially triangular at the base end side of the small-diameter hole. There is a triangular hole in which the tops of the triangles are formed flat.

[0006] A holder for holding the rod-shaped cosmetic is accommodated in the triangular hole so as to be movable in the axial direction. At the lower part of the triangular hole, there is provided a large-diameter hole having a diameter slightly larger than that of the triangular hole, and a spring for pulling the holder downward (in a direction in which the holder approaches the container body) is provided in the large-diameter hole. One end is hanging. A cap for preventing attachment / detachment is attached to the large-diameter hole so that the holder and the spring do not fall out of the storage cylinder.

Thus, even if the cartridge is handled alone, the components of the cartridge do not fall apart, and the stick-shaped cosmetics of the stick-shaped cosmetic supply container are used up, or the stick-shaped cosmetics of different colors are used. When it is desired to use the cartridge, the cartridge mounted on the outer cylinder can be replaced with another cartridge.

[0008] In the stick-shaped cosmetic dispensing container, when the outer cylinder is rotated forward with respect to the cartridge, the push-out bar moves upward. The cosmetic is projected from the cartridge. On the other hand, when the outer cylinder is reversely rotated with respect to the cartridge, the push rod follows and descends, and the stick cosmetic is drawn into the cartridge.

[0009]

However, in the cartridge, the base of the stick-shaped cosmetic is rigidly attached to the holder, and the tip of the stick-shaped cosmetic is inserted into the small-diameter part through a slight gap. Therefore, when an external impact is applied to the stick-shaped cosmetic material feeding container, the impact acts on only a part of the stick-shaped cosmetic material, not the entire axial direction. That is, the impact load is concentrated on the holder-side end of the small-diameter hole at the tip of the rod-shaped cosmetic and the tip of the holder, and a large shear force acts on these parts, so that the rod-shaped cosmetic may be damaged. There is.
