Description

Lead holder of cartridge for makeup pencil

The present invention relates to a cosmetic pencil (PENCIL) of a cartridge (CARTRIDGE) type, and more particularly, to a cosmetic pencil cartridge which can stably move a cosmetic core material injected into the cartridge. Relates to a shim holder.

Cosmetic pencils include lipstick (LIPSTICK), eyebrow pencil (EYEBROW PENCIL), etc. In particular, the core material is to be drawn in and drawn out to be used conveniently.

1 is a cross-sectional view showing an example of a conventional cosmetic pencil, referring to this, a cartridge is inserted into the inside of the pencil case 1, which is a main body 2, a screw tube 3 and a holder (4) Consists of

The main body 2 has a guide hole 5 through which the inside is penetrated in the longitudinal direction, and a stepped jaw is formed in the middle thereof, and a rear end of the stepped jaw becomes a connecting pipe 6 so that the connecting pipe 6 is connected to the screw pipe ( 3) the guide groove (7) is formed in the longitudinal direction at the outer periphery of the connecting pipe (6), the screw groove (8) is formed in the screw pipe (3), the connection It is fitted rotatably on the outside of the tube (6).

The holder 4 is assembled to the inside of the main body 2, and the holder 4 is formed to have a long tubular shape, and a protrusion 9 is formed at the rear end of the outer circumference to form the guide groove 7. It is engaged with the screw groove 8 of the screw pipe 3 through.

In addition, the cosmetic core 10 is injected and fixed inside the holder 4.

Accordingly, when the screw tube 3 is rotated while holding the main body 2 of the cartridge, the holder 5 is moved inside the connection tube 4 to remove the cosmetic core 10 seated on the holder 5. When it is pulled out and rotated in reverse, the cosmetic core is drawn in.

The case 1 is fitted and fixed to the outside of the screw tube 3, and in the case of actual consumer use, the front end of the case 1 and the cartridge body 2 are gripped and rotated oppositely to each other. The screw tube 3 rotates to draw and pull the core material.

Due to this configuration and function, the conventional cartridge type lipstick is easy to carry and store because the cartridge can be removed from the case in some cases, and the cartridge can be replaced after use. It provided an advantage.

However, the following problem has been pointed out of such a conventional cosmetic pencil cartridge.

That is, a state in which the cosmetic core is injected into the holder is shown in cross section in FIG. 2, and FIG. 3 illustrates a state in which the solidified core is separated from the holder, as shown in the front and the holder of the holder. Since the step (d) with the injected portion is large, there is a problem that the core 10 is easily broken even with a small impact.

In addition, in the manufacturing process, the core material is injected and filled into the liquid state from the rear or front of the holder, and then cooled to solidify rapidly. The holder made of the synthetic resin injection molding has a low thermal conductivity, and thus the inner side of the holder is lower than the outer core part which is exposed. The portion of the core is relatively slow in cooling rate, and the front portion of the core is different from the property of solidification, so that cracks are likely to occur in the portion where the step is formed, and in consideration of this point, the cooling temperature is further lowered to cool. Accordingly, there is a problem that the quality of the product is deteriorated due to poor molding state such as the front portion of the core material is warped or the surface is distorted.

Figure 4 shows the state of movement of the conventional cosmetic core material is represented by leaping the state of bending to point out the problem. As shown in the drawing, the cartridge body 2 often has a fine eccentricity or tolerance therein, and in this case, when the holder 4 is moved by the rotation of the screw tube, the core material ( Since the holder 4 including 9) is moved in a linear motion, the tip of the core 9 is prepared to come into contact with the inner circumferential surface of the main body 2, and thus, stress is applied to a part where the stepped portion, which is a weak part of the core, is formed due to frequent contact. Occurred and eventually the heart was broken during use, and the product was discarded without being used much.

The present invention is to solve the conventional problems as described above, the object of the cosmetic pencil cartridge is to maintain the rigidity of the core material by reducing the step difference between the portion and the outer portion injected into the holder when the core material is formed To provide a shim holder.

Another object of the present invention is to provide a shim holder of a cosmetic pencil cartridge which allows cooling to be made quickly even in the inner part of the holder during cooling after injection of the core material in the manufacture of the cosmetic pencil cartridge.

Still another object of the present invention is to prevent the core from being broken or deformed even when the core is in contact with the inner circumference of the body when the core is moved because the inner circumference of the cartridge body is somewhat eccentric or has a tolerance when using the cosmetic pencil. To provide a shim holder of a cosmetic pencil cartridge that can be.

Therefore, the general object of the present invention, in the cosmetic pencil, the shim holder of the cosmetic pencil cartridge that can maintain a stable state of the core material and can be maintained for a long life to improve the confidence of the product for consumers To provide.

The shim holder of the cosmetic pencil cartridge according to the present invention, in order to achieve the above object, in the holder assembles to be movable in the interior of the cartridge body, the tube is formed with projections on the outer periphery of the rear end, A holder having an engaging groove formed at an outer circumference of the end portion; The middle portion is formed with a protruding part slightly inwardly, the rear end is characterized in that it comprises an auxiliary holder is formed in the locking step bent inward to be fitted into the engaging groove of the holder.

In addition, another feature of the present invention is that grooves formed on both sides of the holder are further divided to provide elasticity at both ends.

Another feature of the present invention is that the auxiliary holder is made of a metal tube.

Since the thickness of the locking jaw of the auxiliary holder is smaller than the width of the locking groove of the holder, the holder and the auxiliary holder are allowed to flow to the side as well as to the front as well as to the side without being separated from each other.

Therefore, when the cosmetic core material is injected into the holder, the auxiliary holder is made of a metal tube, so that the temperature can be quickly transferred due to the cooling, thereby minimizing the cooling variation with the outer portion, and in using the cosmetic pencil. Even when the outer side of the core material comes into contact with the inner circumferential surface of the cartridge body during the movement of the holder, since the auxiliary holder is properly bent and moved from the holder, breakage or deformation of the core material can be prevented.
