Description

[Detailed description of the invention] This invention houses a cosmetic applicator inside the cartridge barrel, and a coil spring that does not come into direct contact with the applicator is built into the rear of the cartridge barrel so that the applicator always stays on. The applicator is housed in the cartridge cylinder by pressing it backward, the cartridge cylinder is removably fitted into the cylinder, and the cap of the cylinder is placed behind the cylinder. A cartridge-type cosmetic applicator that allows makeup to be applied by pushing out the applicator part from a cartridge barrel inserted into a cylindrical member when worn, and the applicator part automatically retracts into the cartridge barrel when not in use. Regarding ingredients.

Conventionally, in this type of cosmetic applicator, a coil spring exists between the periphery of the application part and the container, which results in a large diameter container, which is not suitable for cosmetic tools where appearance is important. Ta.

Further, in this conventional structure, since a coil spring exists around the applicator, there is a problem in that the brush or the like which is the applicator comes into contact with the spring.

The present invention was developed in view of the above circumstances, and its purpose is to increase the diameter of the cartridge by incorporating a coil spring inside the rear of the cartridge cylinder of a cosmetic applicator without directly contacting the application part. To provide a cartridge-type cosmetic applicator that does not cause damage to an application part due to a spring.

An embodiment of the present invention will be described below with reference to the drawings. The cartridge-type cosmetic applicator of the present invention includes a cartridge cylinder body 1 made of metal or hard plastic and having open front and rear ends. An applicator 3, such as a brush, a brush, or a sponge, which can be retracted from an opening 2 at the front end of the body 1; The rod rod 5 housed in the rod rod 5 and the cartridge cylinder body 1 provided at the rear end of the rod rod 5.
An expansion part 6 movably accommodated in the space inside the cartridge, a locking part T protruding toward the center at the center of the cartridge barrel 1, and a locking part T interposed between the locking part 7 and the expansion 6. a cartridge cylinder body having a coil spring 8; a cylinder body in which the rear part of the cartridge cylinder body 1 can be inserted and removed, the front and rear ends are open, and the front outer diameter and the rear outer diameter are substantially the same; a cylindrical spring 11 that is a member 10 and is housed in front of the cylindrical member 10 and holds the cartridge cylindrical body 1 in an inserted state; a push rod 12 that is housed in the cylindrical member 10 so as to be able to reciprocate; a cylindrical member 10; and a cap 13 that can be attached even when the cylindrical member 10 falls forward and backward, and protrudes from the bottom of the cap 13 toward the opening of the cap 13. Set push rod 1
4, the cap 13;

9 in the figure is an inner cylinder that is fitted into the cartridge cylinder 1 at t to form the locking part 7 in the cartridge cylinder 1;
This inner cylinder 9 is made of hard plastic.
A locking portion 7 is formed at the front end of the inner cylinder 9, and a flange that matches the outer diameter of the cartridge cylinder body 1 projects from the rear end of the inner cylinder 9.

This inner cylinder 9 may be fixed to the cartridge cylinder body 1 by press-fitting or the like, or a combination of press-fitting and adhesive may be used.

By using this inner cylinder 9, assembly can be easily performed even when the opening 2 of the cartridge cylinder 1 is narrower than the body and has a smaller diameter than the root 4 of the applicator 3.

Reference numeral 15 denotes a retaining ring fitted into the front end opening of the cylindrical member 10, which restricts the cylindrical leaf spring 11 from coming out from the cylindrical member 10.

Reference numeral 16 denotes an inner cylindrical member inserted into the inside of the cylindrical member 10, which is made of hard plastic, and the cylindrical member 16 is fixed to the cylindrical member 10 by forced press-fitting or by using adhesive in combination with this.

Reference numeral 17 denotes an engaging portion formed in the center of the inner cylinder member, and the push rod 12
The retraction force of the coil spring 200, which will be described later, is restricted.

Reference numeral 18 denotes a large diameter portion provided in the middle portion of the push rod 12, and this large diameter portion 18 restricts the retreating position of the push rod 12 by being caught on the aforementioned engaging portion 17.

19 is a butt plug fixed to the rear end of the push rod 12;
By interposing the coil spring 20 between the push rod 12 and the engaging portion 17, when no external force is applied to the push rod 12, the push rod 12 can be pushed into the cylindrical member 10 by repulsive force and positioned at the rear. .

21 is a cylindrical leaf spring attached to the inner wall of the cap 13;
When the cap 13 is attached to the front end or the rear end of the cylindrical member 10, the cap 13 is reliably maintained in a state where the cap 13 is attached to the cylindrical member 10; 22 is the cap 1;
It is a stopper that is fixed to the top of 3 and has a push rod 14 protruding from it.

The cosmetic applicator of the present invention is as described above, and the applicator 3 is a brush, a brush, a sponge, etc., and each of these applicators is housed in a separate cartridge barrel 1. The cartridge cylindrical body 1 containing an arbitrary applicator can be inserted into the cylindrical member 10 from the front end opening of the cylindrical member 10 and held by a cylindrical leaf spring, and by replacing the cartridge cylindrical body 1, The type and color of the application section 3 can be changed and used.

Then, the cap 1 attached to the front of the cylindrical member 10
3 is removed and this cap 13 is attached to the rear of the cylindrical member 10, the push rod 14 of the cap 13 presses the push rod 12, and the push ring 12 presses and moves the rod 5 to open the application section 3. Makeup can be applied by protruding from the opening 2, and when the cap 13 is pulled out from the rear of the cylindrical member 10 after applying makeup, it is pressed by the push rod 14 via the push rod 12 and protrudes from the opening 2. Since the applied applicator 3 is automatically retracted into the cylindrical body 1 by the repulsive force of the coil spring 80, there is an advantage that the applicator 3 does not stain clothes or the inside of a backpack when not in use.

Furthermore, according to the present invention, the coil spring is not wound around the application part, but can be made very thin and slim as a whole, including the cartridge cylinder, the cylindrical member that combines it, and the cap. This makes it possible to obtain cosmetic tools with an excellent appearance.
