Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cartridge-type cosmetic bar, in which a core made of a cosmetic bar is housed in a cartridge body, and the cartridge body is mounted on a holder for use.

Conventionally, there has been a cartridge-type bar-shaped cosmetic product of this type, such as the one described in Japanese Patent Application Laid-Open No. 120853/1983.

However, in the conventional structure described above, since a coil spring is present between the periphery of the rod-shaped cosmetic core and the cartridge body, the diameter of the cartridge body is thicker than the diameter of the rod-shaped cosmetic core, resulting in an undesirable appearance. This may not be desirable for cosmetics that place emphasis on the appearance of hair, and thick and short hair may be difficult to handle.

In the conventional structure described above, there is a coil spring around the rod-shaped decorative core, so when the spring is contracted, the rod-shaped decorative core may come into contact with the rod-shaped decorative core. When it reached the entrance of the container, it touched the coil spring and got scraped.

The present invention has been made in view of the above, and embodiments of the present invention will be described below with reference to the drawings.

A rod-shaped cosmetic core 2 is slidably housed in a cylindrical cartridge body 1 that can be attached to and detached from a holder by, for example, a leaf spring.

A tension coil spring 3, which always has a force to reduce the size, is interposed between the lead chuck 6 that holds the rear end of the rod-shaped decorative lead 2 and the rear part of the cartridge body 1.
and the rear end 5 is connected to the lead chuck 6 and the annular tail plug 7 at the rear of the cartridge body 1, respectively.

An opening 8 is provided in the tail plug 7 fitted to the rear of the cartridge body 1, and a push rod 1 of the holder 9 pushes the rod-shaped cosmetic lead 2 forward against the tension of the coil spring 3.
0 can be inserted.

11 in the figure is a cap.

In carrying out the present invention, the rear end 5 of the coil spring 3, which is a tension spring, may be directly connected to the cartridge body 1 without using a mounting member such as the tail plug 7.

In addition, in order to connect the coil spring 3 to the core chuck 6 and tail plug 7, a male threaded mounting portion is formed on the core chuck 6 and tail plug 7, and the tip 4 of the coil spring 3 is attached thereto.
It is preferable to screw the rear end 5 and the rear end 5 together.

The structure of the holder 9 can be a spiral structure, such as the lead feeding structure of a normal mechanical pencil, and the cartridge main body 1 can be inserted and attached by a leaf spring inside the holder.

The cartridge-type bar-shaped cosmetic product constructed according to the present invention is as described above, and when it is not attached to the holder 9 and is not in use, the bar-shaped cosmetic core 2 is retracted into the cartridge body 1 by the tension of the tension coil spring 3, so that it does not protect hands or clothes. The rod-shaped decorative core 2 can be made to protrude from the cartridge body 1 by attaching it to the holder body and pressing the rod-shaped decorative core 2 with a push rod 10 without making it dirty.

In addition, in the present invention, since there is no coil spring around the rod-shaped cosmetic core in the above-mentioned cartridge-type cosmetics, the overall structure can be made very thin and slim, and the overall length can also be shortened. This makes it look good, and the rod-shaped decorative core does not come in contact with the coil spring and prevent it from interfering with sliding or being scraped.

When the coil springs are connected by screwing as described above, the rod-shaped cosmetic lead receives an appropriate rotation restraining force from the cartridge body, and the cosmetic lead does not rotate during use, making it very easy to use.

Further, when the tip of the cartridge main body is cut diagonally as shown in FIG. 1, the cosmetic lead completely returns to its original position when stored, so that no part of it is exposed.

Manufacturing is facilitated by inserting the cartridge body into the holder using the leaf spring inside the holder, and the combination of the cartridge and holder is determined by the relationship between the outer diameter of the cartridge and the inner diameter of the leaf spring, the inner diameter of the opening 8, and the push rod. Any combination can be conveniently used as long as the relationship with 10 is compatible.

In addition, in the case of the embodiment shown in FIG.
can be supported over the entire inner wall of the cartridge body 1, so that the rod-shaped cosmetic core is held securely, and the rod-shaped cosmetic core does not wobble when applying makeup, and only the inner wall of the cartridge body 1 touches the outer periphery of the rod-shaped cosmetic core 2. This has the advantage that the peripheral wall of the rod-shaped decorative core 2 is not scraped.
