Description

[Detailed description of the invention] The present invention relates to an extruded container for bar-shaped cosmetics such as lipstick, and when metal is used as a part of the exterior of the synthetic resin body to give it an excellent appearance. The object is to easily and reliably assemble the main body and the metal piece.

Extruded containers for bar-shaped cosmetics and the like are usually made of synthetic resin because of their ease of molding, but since the appearance of these types of containers is extremely important, metal parts are fitted in some parts to improve the appearance. Efforts are being made to make it even more beautiful.

As a means of integrating this synthetic resin member and metal member, if the synthetic resin part is insert-molded using a pre-formed metal part as part of a mold, the assembly of the two will be extremely secure. There were drawbacks such as difficulty in positioning the part when it was made into a part of the mold, making molding difficult and increasing manufacturing costs.

For example, it is possible to assemble a cylindrical metal member to a cylindrical synthetic resin part, but the molding accuracy of synthetic resin is not comparable to the molding accuracy of metal as long as it is fitted so that there is a perfect surface contact. Because of the poor quality, there was a risk of looseness or failure to fit.

The present invention was devised in order to eliminate such inconveniences, and it makes the assembly of the synthetic resin container body and the metal decorative body secure and agile, thereby improving the appearance of the cosmetic container. This is intended to improve the appearance, and one embodiment thereof will be described below with reference to the drawings.

The extruded container made of synthetic resin shown here has an outer cylinder 20 rotatably but unremovably fitted into an inner cylinder 10, and a tray 30 for storing bar-shaped cosmetics A is slid. It is assembled into the inner cylindrical body 10 so that it can move up and down, and the outer cylindrical body 2
A cap 40 is attached to cover the 0.

That is, first, the inner cylindrical body 10 has a rotary grip portion 1 at the lower end of the peripheral wall 11.
2 are continuously molded, and a linear guide hole 13 is formed in the peripheral wall 11 along the axial direction.

The outer circumferential surface of the continuous portion between the peripheral wall 11 and the rotating gripping part 12 is a stepped part 14 in such a manner that the gripping part 12 protrudes. An outer flange 16 is provided at each of the upper end outer flange 15 and the outer cylindrical body 20 is fitted tightly onto the peripheral wall 12 between the upper outer flange 15 and the step 14.

Further, in this embodiment, the outer cylinder 20 has two inner circumferential line grooves 21 extending from the upper part to the lower part, and as described above, the inner peripheral surface line groove 21 is provided on the peripheral wall 11 of the inner cylinder 10 so as to be rotatable but not removable. It will be packaged in

Next, a saucer 30 for storing stick-shaped cosmetics such as lipstick is fitted into the inner cylindrical body 10, and its peripheral wall 3
1, a protruding shaft 32 is provided on the outer surface, and this protruding shaft 32
penetrates through the guide hole 13 of the inner cylinder 10 to the outer cylinder 2.
0's facial expression 21 and incorporates it.

Therefore, the tray 30 on which the bar-shaped cosmetic product A is placed is the inner cylindrical body 10.
By mutually rotating the and outer cylinder body 20, the protruding shaft 3
2 is guided by the guide hole 13 and the marking 21 to form the inner cylinder 10.
The bar-shaped cosmetic product A can protrude from the upper end of the inner cylindrical body 10 by sliding and moving up and down while maintaining the horizontal state.

Furthermore, a cylindrical metal gripping body 50 is externally fitted onto the rotating gripping portion 12 at the lower part of the inner cylinder 10 described above.

This gripping body 50 is intended to improve the appearance by covering the inner cylinder body 10 made of synthetic resin exposed at the lower part, and its lower end is above the outer flange part 16 at the lower end of the rotating gripping part 12. It is mounted firmly and immovably on the gripping part 12 by appropriate means.

The upper end of the gripping body 50 is located above the lower part of the outer cylindrical body 20, and an outer flange 51 is bent into a band shape at the upper part. It is designed to fit into the upper part of the grip body 50.

By the way, in the present invention, the cylindrical metal decorative body 6 is also provided on the outer cylindrical body 20 which is exposed to the outside when the cap 40 is removed.
0 is externally fitted.

The upper end of this decorative body 60 is slightly tapered inward, and completely covers the outer cylinder 20 to the extent that it reaches the upper end of the rotary grip part 12 at the bottom of the inner cylinder 10. body 2
0 and the decorative body 60 must be firmly assembled.

Otherwise, the outer cylindrical body 20 and the inner cylindrical body 10 will not be able to rotate relative to each other, and will spin idly, making it impossible to take the cosmetic product A in and out.

Accordingly, in the present invention, the mutual assembly of the outer cylindrical body 20 and the decorative body 60 is reliably achieved by the following configuration.

That is, the above-mentioned outer cylinder 20 has a circumferential groove 22 on its lower outer circumferential surface.
The bottom surface of the circumferential groove 22 is provided with engaging convex portions 23 at predetermined intervals along the circumferential direction, while the lower inner circumferential surface of the decorative body 60 is provided with engaging convex portions 23 at predetermined intervals along the circumferential direction. A large number of retaining protrusions 61 are provided along the circumferential direction at regular intervals by press working, corresponding to the circumferential groove 22 of the outer cylinder 20.

Therefore, when the decorative body 60 is fitted into the outer cylinder body 20 from above, the engagement protrusion 61 is assembled into the circumferential groove 22 of the outer cylinder body 20, and mutual assembly in the vertical direction is achieved.
Moreover, the engagement protrusion 61 engages in the circumferential direction with the engagement protrusion 23 provided on the bottom surface of the circumferential groove 22, thereby preventing mutual rotation in the circumferential direction.

Since the extruded container according to the present invention has the configuration as described above, the outer cylinder body 20 made of synthetic resin and the decorative body 60 made of metal are arranged in the circumferential groove 22, the engagement protrusion 23, and the engagement protrusion. The assembly and engagement with 61 reliably prevents mutual removal and rotation in the circumferential direction, and the assembly becomes a solid body.

In this case, it is obvious that the more the circumferential groove 22 of the outer cylinder 20 and the engagement protrusion 61 of the decoration body 60 are arranged in multiple stages vertically, the more firmly the mutual assembly will be made. Since the decorative body 61 is formed by press working, a recess is formed on the outer surface of the decorative body 60, resulting in an unsightly appearance.

Therefore, in this embodiment, the engaging protrusion 61 is provided at the lower part of the decorative body 60 so that the upper end of the gripping body 50 fixed to the inner cylinder body 10 covers the recess formed at the lower part of the decorative body 60.

When using the container according to the present invention, the cap 40 is pulled out from above the grip body 50, and the decorative body 6 is removed.
0 and rotate the grip body 50 in a predetermined direction, the inner cylinder body 10 integrated with the grip body 50 and the outer cylinder body 20 integrated with the decoration body 60 mutually rotate, The tray 30 inside the inner cylinder 10 rises, and the bar-shaped cosmetic A protrudes from the upper end of the inner cylinder 10.

In this manner, the present invention synthesizes a metal decorative body 60 by engaging the engagement protrusion 61 protruding from the decorative body 60 with the circumferential groove 22 and the engagement protrusion 23 of the outer cylinder body 20. Since the outer cylinder body 20 made of resin is assembled and held in a manner that cannot be rotated or removed, a large error occurs between the molding dimensions of the outer cylinder body 20 and the decorative body 60, and this outer cylinder body Even if a gap occurs between the decorative body 20 and the decorative body 60, the decorative body 60 will be attached to the outer cylindrical body 20 due to the engagement of the engaging protrusion 61 with the circumferential groove 22 and the engaging protrusion 23. It will be firmly and immovably assembled and held.

As is clear from the above description, the extruded container according to the present invention has a luxurious exterior texture because the metal decorative body can be firmly, reliably, and easily fitted into the synthetic resin cylindrical body. The product is extremely beautiful, and since the structural irregularities for this assembly are covered, it has an even better appearance, making it an excellent and useful container for high-end cosmetics.
