Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container for a makeup brush used when applying cosmetics such as lipstick.

[Conventional technology]

BACKGROUND ART A makeup brush is generally used when applying cosmetics such as lipstick, blusher, and eyeshadow.

However, these types of cosmetics naturally have different colors, physical properties, and uses even if they are the same type of product, so it is necessary to prepare makeup brushes specifically for each type of cosmetic. Ta. Therefore, makeup brushes are bulky, making them inconvenient to carry, and there is always the inconvenience of having to discard them if they are used incorrectly.

Also, makeup brushes become damaged as they are used repeatedly.
It could not be used beyond a certain point because it would get dirty.

[Problem that the idea aims to solve]

Therefore, it is desirable to store a long makeup brush lead in a designated container and to be able to pull it out and cut off the tip as it is used repeatedly, but it must be held securely after being pulled out. It was difficult to use, and if it was pulled out more than necessary, it could not be returned to its original state and was wasted.

The present invention relates to a container for storing makeup brush leads, which was devised to solve the above-mentioned conventional drawbacks and inconveniences. To securely hold a makeup brush lead and keep the tip of the makeup brush lead always fresh.

[Means for solving problems]

The cosmetic brush lead container of the present invention is composed of a main body tube 1, an operating tube 14, and a makeup brush lead 19.

The main body cylinder 1 has a first locking protrusion 3 on the inner circumferential surface of the tip.
The operation cylinder 14, which is assembled to the tip of the main body cylinder 1 so as to be freely forward and backward, has a second locking protrusion 17 protruding from its inner peripheral surface.

The makeup brush lead 19 is a long piece made of a soft material with high elasticity and is used for applying cosmetics. It protrudes from the distal end, and is movable forward by the locking protrusions 3 and 17, but is locked from the proximal end side so as not to be movable backward.

[Effect]

In the above structure, when the makeup brush lead 19 is fitted into the main body cylinder 1 and the operating cylinder 14, the respective locking protrusions 3 and 17 bite into the main body cylinder 1 and the operating cylinder 14, so that the makeup brush lead 19 is securely inserted into the main body cylinder 1 and the operating cylinder 14. It is put into use by having its tip protruded from the tip of the operating barrel 14.

In this case, the makeup brush lead 19 is attached to each locking protrusion 3, 1.
7 from the proximal end side, the distal end can slide in the forward direction within the main body tube 1 and the operating tube 14, but cannot slide in the proximal backward direction.

Now, when the operating barrel 14 is advanced in the forward direction with respect to the main barrel 1 to the forward limit in the above posture, the operating barrel 14
The makeup brush lead 19, which is locked by the second locking projections 17 of No. 4, also moves forward together with the operation tube 14 and slides inside the main body tube 1.

Then, when the operating barrel 14 is moved back in the opposite direction at the forward limit of the operating barrel 14, the makeup brush lead 1
9 does not slide in the base end backward direction, the tip of the makeup brush lead 19 remains and protrudes from the tip of the operating barrel 14 by the amount that the operating barrel 14 moves forward.
By cutting off the dirty part of the tip of the makeup brush lead 19, it can be used as a fresh makeup brush lead 19.

〔Example〕

In the illustrated embodiment, the main body tube 1 has a cylindrical tube wall 2 and has an outer diameter equal to that of the tube wall 2 at the tip thereof,
It has a configuration in which a short cylindrical assembly wall 6 having an inner diameter slightly larger than that of the cylindrical wall 2 is integrally connected via a step 13, and a plurality of first engagement walls are formed on the inner circumferential surface of the tip of the cylindrical wall 2. Stop projections 3 are provided projecting along the circumferential direction at predetermined intervals.

This first locking protrusion 3 is composed of an inclined part 4 that is gently inclined from the proximal end toward the distal end, and a vertical part 5 whose distal end is cut at an acute angle. The protruding end of the vertical portion 5 bites into the makeup brush lead 19 and locks therein. In addition, this locking protrusion 3 is
As long as the makeup brush lead 19 can be securely retained as described above, it may be only one piece.

Further, a pair of guide grooves 7 are carved in the inner circumferential surface of the assembly wall 6 so as to face each other. This guide groove 7
A lock groove 9 is continuously carved along the circumferential direction at the base end of the vertical groove 8 provided along the axial direction, and a circumferential groove 10 is continuously carved along the same circumferential direction at the tip of the vertical groove 8. Furthermore, an insertion groove 1 is provided at the opposite end of the circumferential groove 10 along the axial direction to the tip of the assembly wall 6.
1 are continuously carved, and a stopper 12 is provided protruding from a continuous portion of the vertical groove portion 8 and the circumferential groove portion 10.

Next, the operation cylinder 14, which is assembled to the tip of the main body cylinder 1 so as to be able to move forward and backward, has a short cylindrical shape, having an outer diameter equal to the inner diameter of the assembly wall 6, and an inner diameter equal to the inner diameter of the cylinder wall 2. It has a configuration in which a tip wall 16 whose outer diameter is slightly larger than the outer diameter of the fitting wall 15 and tapers in the distal direction is integrally connected to the tip of the fitting wall 15, and the inner peripheral surface base end of the tip wall 16 The second locking protrusion 17 is provided to protrude from the outer peripheral surface of the fitting wall 15, and a pair of guide pins 18 are provided to protrude from the base end of the outer peripheral surface of the fitting wall 15 in correspondence with the pair of guide grooves 7. The second locking projection 17 here has the same configuration as the first locking projection 3 described above.

Therefore, by fitting the fitting wall 15 into the assembly wall 6 and simultaneously fitting the guide pin 18 into the guide groove 7, the operating tube 14 is assembled to the tip of the main body tube 1.

In this case, first insert the guide pin 18 into the groove 11.
The operation tube 14 is fitted into the circumferential groove 10, the operation tube 14 is rotated in a predetermined direction, the guide pin 18 is fitted into the vertical groove 8, and the operation tube 14 is further pushed in the axial direction of the main body tube 1 to be assembled. to rotate the operation tube 14 in the predetermined opposite direction and release the guide pin 18.
By fitting the vertical groove 8 into the lock groove 9, the operating barrel 14 is prevented from moving forward uncontrollably.

Further, the forward movement of the operating barrel 14 is stopped in a position where the guide pin 18 is located at the tip of the vertical groove 8, which is the forward limit of the operating barrel 14, but when an attempt is made to rotate the operating barrel 14 in a predetermined reverse direction, the guide pin 18 18 is the vertical groove part 8
Since the guide pin 18 comes into contact with the stopper 12 at the continuous portion of the circumferential groove 10, the rotation is prevented, and the guide pin 18 comes off from the insertion groove 11, and the operating cylinder 14
will not come out of the main body tube 1 unnecessarily.

From the above-mentioned configuration, the amount of advance of the operation barrel 14 and the amount of advance of the makeup brush lead 19 are determined by the length of the vertical groove portion 8.

Next, the long makeup brush core 19 is made of rubber material, for example.
Molded from sponge material, easy to apply makeup.
The best option is one that is easy to cut and allows the locking protrusions 3, 17 to bite into it easily.

In addition, an end cap 20 is attached to the base end of the main body cylinder 1.
is embedded.

[Effect of idea]

As is clear from the above description, the cosmetic brush lead container of the present invention allows for easy forward movement of long cosmetic brush leads, and the ability to easily cut off the dirty tip to make a fresh one. Since the makeup brush lead is firmly held and does not move back, it is easy to use, has a simple structure, and is easy to mold and assemble, and has many excellent effects.
