Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bar-shaped cosmetic container for lipstick, eye shadow, etc. In particular, the barrel tube, which is the exterior member of the container, is connected to the front tube that stores the solid cosmetic. The present invention relates to a container for dispensing a fixed amount of cosmetics, which enables confirmation of dispensing of a fixed amount of cosmetics visually, tactilely, and auditorily when relatively rotated.

[Prior art and its problems]

In bar-shaped cosmetic products such as lipsticks and eye shadows that have a dispensing mechanism, solid cosmetics are usually stored inside the tip tube, and the cosmetics are dispensed from the front end of the tip tube by manually turning a shaft tube connected to the rear end of the tip tube. It is designed to advance or retreat. The overall shape of such a dispensable bar-shaped cosmetic container is usually cylindrical, and the tip tube and stem tube are cylindrical, so in order to obtain the optimal amount of dispensing for makeup, the stem tube is set to the tip tube. I can't tell how many times I rotated it. Therefore,
The user should carefully check the length of the cosmetic that protrudes from the tip of the tip tube each time he or she applies makeup, in order to avoid damaging the cosmetic by extending the cosmetic more than necessary. However, it was troublesome to have to adjust the amount to the optimum amount.

In addition, in conventional cosmetics, the tip tube and the barrel rotate uniformly and freely, so when applying makeup, the cosmetic may move backward due to the unexpected rotation of the barrel, resulting in the cosmetic not being placed in a fixed position. It may be difficult to apply makeup, or even when stored, for example, when carried in a handbag, the barrel may rotate naturally due to vibrations, causing the cosmetics to protrude and hit the bottom of the cap, causing the cosmetics themselves to be damaged. There were also problems.

[Purpose of invention]

The present invention was developed in view of these circumstances, and its purpose is to visually, tactilely, and audibly determine how many revolutions the shaft tube is rotated relative to the tip tube in order to obtain the optimal amount of extension for makeup application. It can be clearly perceived with all senses, and a constant amount of cosmetics can be dispensed at all times, and when the shaft cylinder rotates relative to the front cylinder, it provides resistance and stabilizes the position of the cosmetics. To provide a stick-shaped cosmetic container that dispenses fixed amounts of cosmetic material without causing accidental protrusion or retraction of the cosmetic material.

[Summary of consideration]

The present invention basically consists of a hollow cylinder consisting of a front cylinder part and a groove pipe part with an oval cross section, and an oval cylinder with a cross section that is almost the same as or similar to the front cylinder part, and a female thread on the inner periphery. It consists of a formed shaft cylinder, a reciprocating shaft having a protrusion, a solid cosmetic at the front end of the retracting shaft, and a concavo-convex portion provided on the shaft cylinder and the hollow cylinder and capable of being fitted and removed by rotation of the shaft cylinder and the hollow cylinder. It is.

[Example of idea]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing a first embodiment of a bar-shaped cosmetic container according to the present invention, and FIG. 2 is a left side view of the first embodiment of the present invention in the position shown in FIG. FIG. 3 is a horizontal sectional view of the first embodiment of the present invention, and FIG.
FIG. 3 is a left side view of the first embodiment of the present invention in the position shown in the figure;

The hollow cylinder 1 consists of a front cylinder part 2 and a groove pipe part 3 at the rear. The front tube portion 2 is a tube for storing cosmetics and has an oval (elliptical) cross section. Here, the elliptical shape refers to an elliptical or track-shaped shape other than a perfect circle. The groove pipe part 3 is
It has a slot 4 that is long in the axial direction.

This groove pipe portion 3 is inserted into the shaft tube 5. The shaft cylinder 5 has a female thread 6 formed on its inner periphery and has an oval cross-sectional shape that is substantially the same as or similar to the cross-section of the front cylinder part 2 .

A reciprocating shaft 7 is inserted into the groove pipe portion 3 . The reciprocating shaft 7 has a protrusion 8 on its outer periphery that protrudes from the slot 4 and engages with the female thread 6, and has an inner plate 9 fixed to its front end. The middle plate 9 is a solid bar-shaped cosmetic 1
The rear end of 0 is fixed. The cosmetic material 10 also has an oval cross section and is housed inside the front barrel section 2 along the inner circumference of the front barrel section 2 .

A cap 11 having an oval cross section can be fitted and removed on the front outer periphery of the shaft tube 5, and the front tube portion 2 and the cosmetic 10 can be housed inside the cap 11.

A bulging body 12 is combined with the rear outer periphery of the groove pipe portion 3. Since the bulging body 12 has an inward protrusion 13 that protrudes inward into the groove hole 4, it is prevented from rotating relative to the groove pipe part 3, but it is prevented from rotating relative to the groove pipe part 3 in the axial direction. is movable. The bulging body 12 has two convex portions 14 at opposing positions in the diametrical direction on the front end surface (see FIG. 5). Two recesses 15 are provided at the rear end of the shaft cylinder 5 at opposing positions through the center, and the recesses 15 can be fitted with the projections 14 of the bulge 12 (see FIG. 6). The rear end of the bulging body 12 is in contact with the front end of a compression coil spring 16 into which the groove pipe portion 3 is inserted.
The coil spring 16 elastically presses the bulge 12 against the shaft cylinder 5.

The inner periphery of an outer cylinder 17 is fitted onto the outer periphery of the shaft cylinder 5, and the outer cylinder 17 includes most of the shaft cylinder 5, the bulging body 12,
The groove pipe portion 3 and the coil spring 16 are housed inside. The outer cylinder 17 is a cylindrical body having a bottom and an oval cross section, and the outer shape is the same as that of the cap 11. Therefore, when the cap 11 is fitted, the container does not have a step on the outer periphery. The cap 11 will not come off due to strong vibrations or shocks. Inside the outer cylinder 17, a stopper 19 is provided in which the grooved pipe portion 3 is fixed inside the center hole 18, and the stopper 19 holds down the rear end of the coil spring 16.

When the cosmetic material 10 is projected, when the shaft tube 5 is rotated in one direction with respect to the front tube section 2, the protrusion 8 moves forward along the female thread 6, and the advancement/retraction shaft 7 moves the cosmetic material 10 into the front tube section 2. protrude from the tip. In order to store the cosmetic 10, the reverse operation may be performed. When rotating the shaft cylinder 5 in this way, since both the front cylinder part 2 and the shaft cylinder 5 have an elliptical cross section, it is necessary to rotate the cylinder 5 by a rotation amount of 1/2 turn or less from a state where the outer shapes match. As a result, a shift (step) is generated between the front cylinder end face 20 and the shaft cylinder end face 21. When the two rotate one-half turn from the initially matched state, the deviation disappears and the outer shapes match again. In this way, every 1/2 rotation there is a "shift"
Since "coincidence" appears, by visually recognizing or touching this, it is possible to know by sight and touch how many rotations the shaft cylinder 5 has been rotated with respect to the front cylinder part 2. Since the amount of the cosmetic material 10 that is dispensed by the shaft tube 5 by one-half rotation is constant, a constant amount of the cosmetic material 10 can be dispensed at all times.

Further, the recess 15 at the rear end of the barrel 5 and the convex portion 14 of the bulging body 12 are fitted together when the front barrel end surface 20 and the barrel end surface 21 match, and the front barrel end surface 20 and the barrel end surface 21 are fitted together. When a deviation occurs between the end face 21 and the bulging body 1
2 compresses the coil spring 16 and the convex part 14 compresses the concave part 1
Get out of 5. When the outer shapes match again, since the bulging body 12 is pressed by the coil spring 16, the convex portion 14 and the concave portion 15 fit into each other with a snapping sound. Therefore, the rotation speed of the shaft cylinder 5 can be known by the sound, and the rotation speed of the shaft cylinder 5 can also be known by the sound.
When rotates relative to the front tube part 2, the convex part 14,
The recess 15 and the coil spring 16 provide resistance to stabilize the position of the cosmetic 10, and the cosmetic 1
0 protrusion or retraction can be eliminated. Convex part 1
4 and the recessed part 15 are desirably made of smooth curved surfaces so that they can be easily inserted and removed, and the concavities and convexities may be provided oppositely to the shaft tube 5 and the bulged part 12. Further, the number of the convex portions 14 and the concave portions 15 may be any number from 1 to 12 as necessary.

Next, a second embodiment of the present invention will be explained in detail.

The fitting sound with 5 is similar to the first embodiment described above, such as knowing the rotation speed of the shaft cylinder 55 with respect to the front cylinder part 52 visually, tactilely, and auditorily, and providing resistance during relative rotation. Having action and effect.

Furthermore, in this second embodiment, the inner plate and the advancing/retracting shaft are integrated without providing a separate bulging body, and
Since the outer cylinder is integrated with the shaft cylinder, the number of parts is small.
With a simple configuration, the same effects and operations as in the first embodiment can be obtained.

[Functions and effects of the invention]

The present invention has the above-mentioned configuration, and since the cross-sections of the front barrel and the barrel are oval, the barrel must be rotated several times relative to the front barrel in order to achieve the optimal amount of extension for makeup. You can tell by sight and touch from the number of times the outer shape of the front barrel matches the outer shape of the barrel. Since recesses and recesses that can be fitted and removed are provided, the rotational speed of the shaft cylinder can also be determined by the light snapping sound that is produced when the recesses and recesses fit into each other. Therefore, the number of revolutions of the shaft cylinder relative to the front cylinder can be known by sight, touch, and hearing, and a constant amount of makeup can always be delivered to achieve the optimum delivery amount.

In addition, in the present invention, the uneven parts of the shaft tube and the hollow tube fit into each other at appropriate positions of relative rotation between the shaft tube and the hollow tube and provide resistance when rotating, thereby stabilizing the position of the cosmetic. It is possible to securely prevent the cosmetic from protruding or receding inadvertently.
