Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a writing instrument used for liquid cosmetics such as eyeliners, eye shadows, and liquid lipsticks.

Conventional writing instruments for liquid cosmetics usually have a filling inside the writing instrument body, and are used to write using liquid cosmetics impregnated into the filling. The reason why the inside cotton is used in this way is that the inside cotton is suitable for the characteristics of the brush, which is often used as a writing tip member, which requires a large amount of cosmetic material instantly.

However, if you store it for a long time while it is impregnated with medium-sized liquid cosmetics, there are risks such as the growth of mold and the growth of bacteria.

Therefore, the inside of the writing instrument itself was not impregnated with cosmetics, but a separate cartridge C two-liquid saccharide was sealed and stored, and the two constituted a writing instrument, which was preserved and sold in this state. When a person starts using the writing instrument, he or she connects the cartridge to the writing instrument body and transfers the liquid cosmetics in the cartridge into the inside of the writing instrument.

Problems to be Solved by the Invention In the above-mentioned conventional writing instruments, when the liquid cosmetic is first used, it is necessary to wait for the liquid cosmetic to be transferred from the cartridge to the filling material, and then to reach the writing point member, and to become ready for writing. This usually takes more than 5.6 minutes, and this has caused a lot of dissatisfaction among users.

Therefore, the present invention was devised for the purpose of speeding up the transfer of this liquid cosmetic and obtaining a writing instrument that can immediately start writing when used.

Means for Solving the Problems The present invention has a flow path that communicates with the second core of the daughter marking device main body C,
A rod-shaped part that enters into the cartridge is provided, so that the cosmetics inside the IJ can be forcibly injected at the beginning of use (while pushing the two rod-shaped parts into the cartridge, push the cartridge into the inside of the cartridge). A writing instrument for liquid cosmetics.

Examples Hereinafter, two examples C will be specifically described to illustrate the present invention. FIG. 1 shows a writing instrument 10 for liquid cosmetics, which consists of a writing instrument main body 11 and a cartridge 12, which are stored and sold separately as shown in this figure.

Inside the main body 11 of the writing implement, there is provided an inner cotton 13, which is made of synthetic fiber, foamed material, etc., and stores liquid cosmetics impregnated therein. It is supplied to a writing tip member 15 having a shape.

Furthermore, the marking tool main body 11 has a rod-shaped portion 16, which protrudes backward (in two directions) so as to cover the outer periphery of the inside cotton 13, and the tip C2 has a channel communicating with the inside cotton 13. 17
It has an O-ring 18 on the outer periphery of the tip. The circumference of this rod-shaped portion 16 is covered with a case 9 with a gap, and a female thread 20 is formed on the inner periphery of the rear end of the case 19. A covering cap 21 is attached.

The cartridge 12 has a generally cylindrical shape as a whole, stores a liquid cosmetic 22 inside, and has a cartridge cap 23 at the tip.
It is covered and sealed. Further, the outer periphery of the rear end of the cartridge 12 has a male thread 24.

When using this writing instrument 10 (2), as shown in FIG. Finally, screw the male screw 24 of the cartridge 12 into the female screw 20 of the writing instrument body 11. In this way, the liquid cosmetic 22 in the cartridge 12 is forced into the inner wad 13 through the flow path 17, and is quickly When the cartridge 12 is pushed in, it is already ready for writing.

FIG. 3 shows another writing instrument 30 for liquid cosmetics.

Like the writing instrument IO, this writing instrument 30 also consists of a writing instrument main body 31 and a cartridge 32, which are stored separately.

The writing instrument main body 311 = is provided with a filling material 33 formed by forming a sheet into a cylindrical shape so as to wrap around the writing point member 34, and supplies the cosmetic material impregnated with the filling material 33 to the side surface of the writing point member 34. Furthermore, the writing instrument main body 31 has a rod-shaped portion 35 that protrudes rearward, and inside this rod-shaped portion 35 (the second is a thin channel 36 is formed to communicate between the tip and the inside cotton 33,
The base of the rod-shaped portion 35 is press-fitted into the case 37 and fixed, and the protrusion 38 that protrudes radially from the base of the writing tip member 34 and penetrates the inner cotton 33 is pressed against the stepped portion 39g of the case 37. The member 34 is fixed. The case 37 covers the rod-shaped portion 35, has a female thread 40 on the inner periphery of the rear end, and has a cap 41 attached to the tip.

The IJ joint 32 has a substantially cylindrical shape and stores a liquid cosmetic 42 therein, and the tip 4 has a small diameter part 43, which is sealed with a ball stopper 44, and a male screw 45 is attached to the outer periphery of the rear end. have.

This writing instrument 30 is used five times as shown in FIG. That is, the cartridge 32 is pushed into the rod-shaped portion 35 of the writing instrument main body 31, the ball stopper 44 is pushed into the cartridge 32, and the liquid cosmetic 42 is poured through the channel 36 while the small-diameter portion 43 is in sliding contact with the outer periphery of the rod-shaped portion 35. C2 is forcibly injected into the cotton 33, and finally the male screw 45 is screwed into the female screw 40 and fixed.

In these embodiments, the cartridge is pushed in straight by hand and only the last part is pushed in by screwing, but the entire cartridge may be pushed in by screwing. Also, when pushing in straight, if the pushing is too fast and causes the button to fall off, increase the friction when pushing in (or
The opening of the flow path may be made small to limit the pushing speed.

In this example, the cartridge itself serves as the rear cover of the writing instrument body, but this is not essential.

In addition, in this example, when pushing the cartridge, the car)
Most of the cosmetics in the IJ Tsuji are forced into the inside of the IJ, but only some of the cosmetics are forced into the inside of the IJ.
: Even if the remaining cosmetics are gradually transferred to the inner cotton using capillary action, the objective of the present invention, which is to shorten the time until writing starts≦2, is sufficiently effective.

Effects of the Invention The writing instrument of the present invention has the advantage that when the cartridge is attached to the writing instrument body as described above (2.
Because it is pushed in twice, the transfer of the cosmetics is quick and can usually be completed within a few seconds.By the time this pushing is completed, the cosmetics have already penetrated to the second place and can be written on immediately. You can start.

Therefore, when using this writing instrument, the user does not have to hold it in a C-shape as in the past, and can begin to use it comfortably.
