Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a stick-shaped cosmetic product dispensing container for dispensing stick-shaped cosmetic products such as lipsticks.

"Prior Art" This type of dispensing container is very well known. An example will be described with reference to FIG. 3. A base cylinder 2a, which serves as a knob cylinder, is integrally fitted to a lower outer surface of a long middle cylinder 1 to form a main cylinder 3, which is rotated on the outer surface of the upper half of the middle cylinder 1. A cylinder 4 is fitted and a lifter 5 is fitted in the middle cylinder 1 so that the lifter 5 can be moved up and down, and a cylindrical middle plate 7 for filling and holding a cosmetic product 6 is inserted into the lifter 5 with a reduced diameter portion 7a in the lower half. It is internally fitted and fixed through the pair of symmetrical spiral grooves 10 on the inner surface of the rotary cylinder 4 through the vertically elongated guide holes 9 and 9 formed on both sides of the middle cylinder 1 by the engaging protrusions 8 and 8. , 10 are engaged with each other, and the cosmetic 6 is drawn out and put in by rotating the main cylinder 3 and the rotary cylinder 4 in opposite directions. 11 indicates a cap.

[Problems to be solved by the invention] In this type of dispensing container, in the structure in which the elevator 5 also serves as a middle plate for filling and holding the cosmetics 6, the cosmetics 6 are filled in the elevator 5 in a retracted state. Therefore, the filling operation of the cosmetics 6 was troublesome. However, in the above-mentioned delivery container, the inner tray 7 for holding the cosmetics 6 is a member different from the elevator 5, and therefore, after each part including the elevator 5 is delivered,
Since the elevator 5 can be extended to the upper limit position and the inner tray 7 can be pushed into and integrally fixed to the inner tray 7, the cosmetic 6 can be filled in the single inner tray 7 without being restricted by other parts of the container.
Has the advantage of facilitating the filling work.

On the other hand, however, by separately mounting the inner tray 7 on the elevator 5, the reduced diameter portion 7a of the inner tray 7 causes the cosmetic 6 to become thin, which causes the cosmetic 6 to be consumed more and more. When the elevator 5 is extended to the upper limit position as described above, or when the cosmetic filling middle plate 7 is attached, if this shaft detail upper end a is located near the container opening, it is directly attached to this shaft detail upper end a. Since an external force acts, there is a problem that it is easily broken.

An object of the present invention is to obtain a stick-shaped cosmetic product dispensing container having a structure in which the axial details of the cosmetic product are not located in the vicinity of the container opening even when the elevator is dispensed to the upper limit position, thereby eliminating the risk of breakage of the cosmetic product.

[Means for Solving the Problems] The present invention is fitted into the middle cylinder 1 and has engaging protrusions 8, 8 on both outer surfaces.
Is engaged with a pair of spiral grooves 10, 10 on the inner surface of the rotary cylinder 4 fitted onto the middle cylinder 1 through the guide holes 9, 9 on both sides of the middle cylinder 1, and is moved up and down in the middle cylinder 1 by a feeding and feeding operation. In the rod-shaped cosmetic feeding container in which the inner tray 7 for holding the cosmetics 6 is fitted and fixed to the elevator 5 via the reduced diameter portion 7a of the lower half, the elevator 5 is
From the outer surfaces on both sides of the short cylinder 5a fitted in the middle cylinder 1, the guide hole is formed.
Arms 12 and 12 that stand up inside 9 and 9 are erected, and the engaging protrusions 8 and 8 are projected from the outer surface of the upper part of the arms 12 and 12.
The reduced diameter portion 7a of the inner plate 7 which is fitted in the elevator 5 is engaged with the protrusion.
The structure is characterized in that it is located approximately 12,12 minutes below the arms 8,8.

[Operation] In the above description, the elevator 5 has the arms 12, which rise upward in the guide holes 9, 9 on both sides of the middle cylinder 1 from the outer surfaces on both upper sides of the short cylinder 5a.
12 is provided, and the engaging protrusions 8 and 8 project from the outer surface of the upper part of the arms 12 and 12. Therefore, as shown in FIGS. 1 and 2, the elevator 5 is extended to the upper limit position. And the short cylinder 5a
Is located below the engaging protrusions 8,8 by the length of the arms 12,12. Therefore, the axial details of the cosmetic product 6 determined by the upper end of the diameter-reduced portion 7a of the inner tray 7 fixedly fitted to the elevator 5 Similarly, the upper end (a) is located below the engaging protrusions (8, 8) by approximately the length of the arms (12, 12), so that external force during application is not directly applied to this shaft detail and breakage etc. The fear of can be eliminated.

[Embodiment] An embodiment will be described below with reference to the drawings. In the present invention, even when the elevator 5 is extended to the upper limit position, the axial detail of the cosmetic product 6 is positioned below the container opening to make it difficult to break. It is characterized by points.

Therefore, as shown in FIG. 1 and FIG. 2, the elevator 5 is inserted into the middle cylinder 1 from both outer side upper surfaces of the short cylinder 5a through the guide holes.
Engagement protrusions that stand up arms 12 and 12 that rise up in 9 and 9 and are engaged with the spiral grooves 10 and 10 from the outer surfaces of the upper ends of the arms 12 and 12.
8 and 8 are projected, and the short cylinder 5a of the elevator 5
A cylindrical inner plate 7 for filling and holding the cosmetic 6 having a stepped shape of the lower half portion 7a is internally fitted and fixed through the reduced diameter portion 7a.

The lower end of the short tubular body 5a of the elevator 5 is slanted slightly inward and downward in the shape of a ridge, while the outer peripheral surface of the lower part of the reduced diameter portion 7a of the inner tray 7 is recessed in a strip shape to engage the outer surface of the lower end. When the inner plate 7 is fitted into the elevator 5 by forming the strips 13, the short tubular body 5a is tightly attached from the upper and lower surfaces by the step portion 14 at the intermediate portion and the engaging projections 13 and integrated with the elevator 5. It has been transformed.

With this structure, even if the elevator 5 is extended to the upper limit position, the short tubular body 5a is located below the arm 12,12 engaging protrusions 8,8, and therefore the shaft detail upper end a of the cosmetic 6 is provided. Also engaging studs 8,
Since the arm 12 is located substantially below the arm 12 for 12 minutes, and this position is considerably below the container opening, the external force applied to the cosmetic 6 does not directly act on the shaft details, so that breakage or the like is unlikely to occur.

It should be noted that each part other than the above is very well known and is the same as before, and since it has already been described, the description thereof will be omitted.

"Effect of the Invention" As described above, in the present invention, in the case where the cosmetic 6 is filled and held in the separate inner plate 7 which is internally fitted and fixed to the elevator 5.
The elevator 5 is provided with arms 12, 12 which rise upward from inside the guide holes 9, 9 on both sides of the middle cylinder 1 from both sides of the outer surface of the short tubular body 5a, and the engaging protrusions 8, 8 are provided on the upper ends of these arms 12, 12. Therefore, even if the elevator 5 is extended to the upper limit position, the short tubular body 5a, in other words, the axial detail of the cosmetic 6 is not located near the container opening, so that the risk of breakage of the cosmetic 6 is eliminated. This improves the reliability of the product. Also, from both outer surfaces of the short tubular body 5a,
Arms 12 and 12 that stand upward in the guide holes 9 and 9 of the middle cylinder 1 are erected, and engaging protrusions 8 and 8 projecting from the upper outer surface of the arms 12 and 12 are provided in the spiral groove 10 on the inner surface of the rotary cylinder 4. Since they are engaged with each other, the portion of the inner tray 7 above the reduced diameter portion 7a can be directly fitted into the inner cylinder 1, so that the diameter of the container can be reduced.
