BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic material feeding mechanism capable of reliably putting in and out a stick-shaped cosmetic material such as lipstick and shadow without damaging it.

[0002]

2. Description of the Related Art There are the following two types of conventional cosmetic material feeding mechanisms. One of them is a dish member that supports the decorative material, a body that houses the dish member, and a dish guide that is rotatably fitted to the upper portion of the body. Then, a spiral groove is formed in the main body, the lower part of the dish member is engaged with the spiral groove, and the rotation stop formed on the dish member is engaged with the vertical groove of the dish guide to relatively rotate the dish guide and the main body. It is a type that moves and draws out cosmetic materials.

On the other hand, the mechanism part is entirely housed in the main body. The dish guide is extended downward to form a protrusion at the bottom of the dish member. The protrusion is engaged with the vertical slit of the dish guide, and the protrusion is further engaged with the spiral groove arranged in the main body. By relatively rotating the dish guide and the main body, It was a type that delivered cosmetic materials.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a dish guide or a dish member provided with a rotation stopper, since the projection or the groove engaging with the projection is in contact with the decorative material, the decorative material itself is damaged,
It has a bad feeling. Further, in the case where all the above-mentioned mechanism parts are housed in the main body, the dish member is divided into an upper part and a lower part and they are fitted and integrated in the assembly process, so that the number of parts is large and the assembly is difficult. It was expensive.

[0005]

In order to solve the above problems, the present invention has a cylindrical shape in which a holding portion for holding a cosmetic material is provided at the upper end to form a spiral groove on the inner circumference and a protrusion is provided on the lower outer circumference. A spiral groove and a vertical groove into which the projection of the cylindrical spiral member fits are formed on the lower inner circumference, and a flange portion is formed on the outer circumference.
The dish guide, an operating rod having a protrusion on the upper end and engaged with the spiral groove of the cylindrical spiral body, and a flat plate of the dish guide on the lower inner circumference.
The inner circumference of the lower end is up
A spiral of a cylindrical spiral body consisting of a main body that engages with the operating rod in a rotationally restrained state, the dish guide from the bottom opening of the main body, the cylindrical spiral body which is not rotatable and slidable in the dish guide, and the upper projection. It is characterized in that it is inserted in the state of being engaged with the groove, and the main body and the operating rod are engaged with each other in a rotationally restrained state, and the flange portion of the dish guide and the large diameter portion of the main body are rotatably fitted .

[0006]

[Operation] When the main body and the dish guide are relatively rotated, the bat rotates and moves with respect to the spiral body. That is, when the cosmetic material is delivered, the bat tries to move toward the lower side of the spiral body, but the lower end of the operating rod is fixed to the main body and cannot move, and the spiral body moves upward. On the contrary, when the cosmetic material is stored, it moves above the spiral body.
The decorative material fixed to the upper part of the spiral body is delivered or stored from the dish guide without rotating.

Embodiments of the present invention will be described with reference to the drawings. 1 is a vertical sectional front view of the present embodiment, FIG. 2 is a vertical sectional front view of the same after feeding out a decorative material, and FIG. 3 is a front view of the same spiral body. In the embodiment of the present invention, as shown in FIG. 1, a spiral body 2 for fixing a decorative material L, an operating rod 20 engaged with the spiral body 2 to rotate, and a dish guide 3 for mounting the spiral body 2 therein.
0 and a main body 50 that rotatably mounts the dish guide 30
And so on.

By the way, the spiral body used for the feeding mechanism is
Created by a split mold, the split surface is 3/100
A parting line, that is, a parting line of about 5 to 100 mm is formed. Further, since the spiral groove is almost formed by the die-molding by resin molding, so much attention has not been paid to the tray bat engaging with the spiral groove.

Therefore, in the spiral body 2 of this embodiment, a resin material 3 is spirally wound to form a cylindrical body having a gap 5 and a hollow portion 2a. As shown in FIGS. 3 to 5, the columns 4 and 4 are fixed, and the dish material 6 and the annular bottom plate 7 are fixed to the upper and lower ends of the columns 4 and 4, respectively.

A holding portion 9 for the decorative material L is provided on the upper center of the dish material 6, and projections 8 are formed on the outer periphery of the bottom plate 7. The spiral body 2 of this embodiment is formed by a split mold. Operating rod 2
As shown in FIGS. 7 to 9, 0 has a structure in which a column 23 is erected on a bottom plate 21 so that it can be inserted into and removed from the bottom plate 7 of the spiral body 2. Further, a ridge 22 is formed on the outer circumference of the bottom plate 21 and a band-shaped fitting portion 21a is provided, and bats 24, 24 are formed on both sides of the upper end of the column 23.

The bat 24 is provided so as to be orthogonal to the longitudinal direction of the column 23. The shape is a horizontally long substantially parallelogram shape as shown in the figure. The upper side and the lower side form parallel horizontal portions 24b and 24b, and the both sides form curved surface portions 24a and 24a. One ends of the curved surface portion 24a and the horizontal portion 24b are connected by a curved surface, while the other end portions are connected in an acute angle to form a pointed portion 24c. And
One point of this curved surface portion 24 a contacts the gap 5 of the resin material 3.

According to this butt (projection) 24, when the bat (projection) 24 having a substantially parallelogram shape formed on the operating rod passes through the parting line formed in the spiral groove during split mold casting of the spiral body 2. Since the sense of resistance such as the feeling of being caught by the curved surface portions 24a formed on both sides of the substantially parallelogram-shaped projection can be eliminated, smooth operation can be obtained.

The bat 2 is provided at the uppermost end of the support column 23.
A notch 25 for fitting 4 into the space 5 is formed. The dish guide 30 has a cylindrical shape capable of accommodating the spiral body 2 and the operating rod 20 therein. Vertical groove 31 on the inner surface below
The vertical grooves 31, 31 are slidably fitted to the projections 8, 8 of the spiral body 2. Further, the flange portion 33 is formed on the lower outer periphery. The flange portion 33 is the main body 50.
Is rotatably engaged with the large diameter portion 53 of the lower inner circumference of the.

The main body 50 is formed with a large-diameter portion 53 which is rotatably fitted to the flange portion 33 at the lower portion of the dish guide 30, and the fitting portion 21a of the above-mentioned operating rod can be freely inserted and removed on the inner periphery of the lower end. A fixing portion 52 that engages with is provided. Further, the protrusions 22 keep the rotation restrained. In the figure, C is a cap.

The operation of the present embodiment will be described based on the above-mentioned structure. The main body 50 and the dish guide 30 are relatively rotated. Then, the operating rod 20 rotates together with the main body 50, and with this rotation, the butt 24 of the operating rod 20 moves along the gap 5 of the spiral body 2. However, since the operating rod 20 is fixed to the main body 50, the operating rod 20 cannot move downward. Therefore, the projection 8 of the spiral body 2 moves upward along the vertical groove 31 of the dish guide 30, and the decorative material L moves to the dish guide. It is fed from the upper end of 30 (see FIG. 2).

As described above, when the bat 24 crosses the parting line 2a of the spiral body 2 in the process of feeding the cosmetic material L, the curved surface portion 24a moves smoothly by contacting the step as shown in FIG. Therefore, there is no sense of discomfort caught in the parting line 2a.

To store the decorative material L, the spiral body 2 may be moved downward by rotating it in the opposite direction. As described above, in this embodiment, since the projection 8 slides upward along the vertical groove 31, the decorative material L can be delivered without rotating with respect to the dish guide 30.

Further, in this embodiment, since it is not necessary to provide the rotation stopper on the decorative material support portion, the groove engaging with the rotation stopper is not formed on the inner surface of the dish guide of the decorative material L, and thus it is fed out as in the conventional case.・ Does not damage the decorative material L when stored. Furthermore, this embodiment has a small number of parts and is easy to assemble. Moreover, by changing the surface material, it becomes a different type of container. In addition, by changing the decorative material support portion, it can be used both for directly filling the decorative material and for the replacement type.

FIG. 6 shows another example of the holding portion for the decorative material L.
The holding portion 10 has a cylindrical shape, and is used when the decorative material L is filled with a die. As shown in the figure, the spiral body 12 has a spiral groove 14 threaded inside a cylindrical body 13 to form protrusions 8 and 8 at the lower end of the outer circumference. The action and effect of this spiral body 12 are the same as those of the spiral body 2, and therefore their explanations are omitted. Therefore, it is possible to configure the holding portion 10 instead of the holding portion 9 of the spiral body 2 or to configure the holding portion 9 instead of the holding portion 10 of the spiral body 12.

[0020]

As described above, according to the present invention, direct filling
However , since the cosmetic material is not scratched, it does not spoil the beauty of the cosmetic product. And since it is composed only of the main body, dish guide, spiral body and operating rod, the number of parts is small and the manufacturing cost is low, and the assembly is done with one touch from the bottom.
Productivity is good because it is pressed in . In addition, since the operating rod is detachably fitted to the bottom of the main body, the feeding mechanism can be easily replaced even if a part is damaged , and especially when the outer cylinder is made of metal such as metal.
It can also be reused by using inexpensive members . In addition, the cosmetic material is delivered from the plate guide without rotating, which makes it easy to use.
