Description

[Detailed Description of the Invention] The present invention is intended to be used as an extrusion container for bar-shaped cosmetics such as lipstick, and is intended to be easily assembled using a small number of parts.

Various configurations have been used as extruded containers for bar-shaped cosmetics such as lipsticks, but recently, extruded containers have been used to minimize the effort required to mold the bar-shaped cosmetics themselves and store them in extruded containers. A method has been adopted in which the container itself is used as part of the mold for forming bar-shaped cosmetics.

When a bar-shaped cosmetic is formed by the above method and stored in an extruded container, the extruded container has the original function of storing the bar-shaped cosmetic and can be used for extrusion, and the extruded container can also be used as a molding frame for the bar-shaped cosmetic. Because the device must also have the following functions, the structure becomes complicated and assembly work becomes troublesome.

The present invention has been devised to solve the above-mentioned disadvantages of the conventional example, and one embodiment of the present invention will be described below with reference to the drawings.

The extrusion container according to the present invention is composed of an outer cylinder 1, an intermediate cylinder 10 forming a storage section for a bar-shaped cosmetic, an inner cylinder 16 forming a tray portion for placing and holding the bar-shaped cosmetic, and a cap 22. There is.

The outer cylinder 1 is constructed by erecting a fitting cylinder piece 4 having a larger inner diameter than the cylinder body 2 at the upper end of a slightly thick cylinder body 2 with a screw groove 3 carved on the inner circumferential surface. , a first step 5 is formed on the inner peripheral surface of the boundary between the cylindrical body 2 and the fitting cylinder piece 4, and a leg cylinder having an inner diameter larger than that of the cylindrical body 2 is formed at the lower end of the cylindrical body 2. By hanging the piece 6, a second step 7 is formed on the inner peripheral surface of the boundary between the cylindrical body 2 and the leg tube piece 6.

The intermediate cylinder 10 has the second second cylinder part 12 at the lower end of the assembled cylinder part 12, which has a longitudinal hole 15 which acts as a guide hole over almost the entire length of the cylindrical body fitted into the cylinder body 2 of the outer cylinder 1. A locking protrusion 14 is provided on the stepped portion 7 of the step 7 from below, and a locking protrusion 14 is provided on the upper end of the assembled cylindrical portion 12 in order to lock the first stepped portion 5 from above. Through the folding stage 13,
A straight cylindrical storage cylinder part 11 having an outer diameter smaller than the inner diameter of the fitting cylinder piece 4 and a larger inner diameter than the assembled cylinder 12 and directly storing a bar-shaped cosmetic product is arranged in series. The intermediate cylinder 10 is integrally formed from a thin metal plate.

The inner cylinder 16 passes through the longitudinal hole 15 and is inserted into the lower end of the outer circumferential surface of a cylindrical leg part 18 having a height substantially equal to that of the assembling cylinder part 12 and is fitted into the assembling cylinder part 12. A threaded piece 19 that threads into the threaded groove 3 is provided protrudingly, and this leg cylinder portion 18
At the upper end, a holding cylinder piece 17 is integrally installed, the outer peripheral surface of which is in close contact with the inner peripheral surface of the storage cylinder part 11, and which is located inside the storage cylinder part 11 and holds the cosmetic bar. be done.

The cap 22 has a capped cylindrical shape, and is assembled to the outer cylinder 1 by fitting its lower end opening into the fitting cylinder piece 4, and forms a storage cylinder part that projects upward from the fitting cylinder piece 4. 11 is coated.

In the case of the illustrated embodiment, the outer diameter of the fitting cylinder piece 4 is set smaller than the outer diameter of the cylinder body 2 by the wall thickness of the opening of the cap 22, so that the fitting cylinder piece 4 is assembled into the fitting cylinder piece 4. The appearance of the container is improved by preventing a difference in level between the outer peripheral surface of the cap 22 and the outer peripheral surface of the cylindrical body 2.

A plurality of protrusions 9 protruding from the outer circumferential surface of the fitting tube piece 4 are provided to make the fitting and assembly of the cap 22 to the fitting tube piece 4 strong.

In addition, the holding cylinder piece 17 has a structure in which the leg cylinder part 18 is simply bent and extended upward, but if you want to hold the bar-shaped cosmetic more firmly, the inner circumferential surface of the holding cylinder piece 17 has a well-known holding protrusion. It is better to have one protruding bottom plate piece.

Further, a groove 20 is vertically formed in the lower end of the inner cylinder 16, and this groove 20 allows the inner cylinder 16 to be fitted and assembled into the intermediate cylinder 10 smoothly. It is something.

Since the extruded container according to the present invention has the above-mentioned structure, the intermediate cylinder 10 is removed by the engagement between the locking protrusion 14 and the second step 7 and the bending step 13 and the first step 5. Although it cannot be removed from the cylinder 1, it is rotatably assembled, and by the engagement of the threaded piece 19 with the vertically elongated hole 15,
The inner cylinder 16 is assembled to the intermediate cylinder 10 so that it can be moved up and down, although it is not rotatable.
On the other hand, by screwing the screwing piece 19 into the screw groove 3, the screwing assembly is completed.

Therefore, when a relative rotational displacement is applied between the outer cylinder 1 and the intermediate cylinder 10, the inner cylinder 16, which is threadedly coupled to the outer cylinder 1 and assembled to the intermediate cylinder 10 in a rotationally undisplaceable manner, , according to the direction of relative rotational displacement between the outer cylinder 1 and the intermediate cylinder 10,
It will be displaced up and down within the intermediate cylinder 10, and thereby the bar-shaped cosmetics placed and held will be taken in and out of the storage cylinder part 11.

As is clear from the above-described structure, the extruded container according to the present invention having the structure and operation as described above has a structure in which the assembled cylinder part 12 of the intermediate cylinder 10 is forcibly fitted into the outer cylinder 1 from above, and the locking protrusion is inserted into the outer cylinder 1 from above. 14 is locked to the second step 7 from below, and the inner cylinder 16 is attached to the outer cylinder 1 before and after the intermediate cylinder 10 is assembled to the outer cylinder 1.
is inserted and screwed into the combination of the outer cylinder 1 and the intermediate cylinder 10.

Now, since the extrusion container according to the present invention has the above-described configuration, the inner cylinder 16 is positioned at the lower limit with respect to the intermediate cylinder 10 as shown in the figure, and the upper end opening of the storage cylinder part 11 is provided with a molding frame. The piece 23 is assembled, the upper end opening of the storage cylinder 11 is sealed, and the extrusion container is turned upside down.

From this state, the material for the bar-shaped cosmetic that is heated and liquefied is injected into the extrusion container from the lower end of the extrusion container that is opened, and the injected and filled material is allowed to cool and solidify, thereby forming the bar-shaped cosmetic. At the same time, storage in an extrusion container is a distant relative.

After the molding and storage of the bar-shaped cosmetic product is completed, the mold frame piece 23 is removed and the cap 22 is attached to complete the product.

By the way, the storage cylinder part 11 which becomes a part of the mold for bar-shaped cosmetics
Since it is made of metal, its inner surface can be made sufficiently smooth, making it possible to form the cosmetic bar beautifully and without damaging the cosmetic bar.
This bar-shaped cosmetic product can be put in and taken out for use.

Furthermore, since this storage cylinder part 11 is made of a thin metal plate, when molding the bar-shaped cosmetic, the cooling force that acts from outside the extrusion container efficiently acts on the material of the bar-shaped cosmetic, thereby making the bar-shaped cosmetic good and efficient. Molding can be a distant relative.

Note that after the injection-filling molding of bar-shaped cosmetics is completed, the opening at the bottom of the extrusion container does not need to be open, so it is better to close the opening at the bottom when commercializing the product. Therefore, as shown in the illustration, a flange-like plate with an opening 10 formed in the center is provided at the lower end of the inner peripheral surface of the leg cylinder piece 6, and this flange-like plate is used to open the hole. It is preferable to configure the closing plate 21 that closes the opening 10 to be fixed.

As is clear from the above description, although the extruded container according to the present invention is used as a mold for molding bar-shaped cosmetics, the number of parts is small, and the assembly between the parts is achieved by simple fitting. Furthermore, it has many excellent effects, such as the ability to mold bar-shaped cosmetics extremely well and efficiently.
