As shown in FIG. 4, the female screw portion 21 of the second case 20 having the “multi-threaded screw structure” includes a first screw thread 211 and a second screw thread 212.

In the embodiment of FIG. 4, the two-row screw structure is described in detail, but three- or four-row screw structures are also possible. However, since there is no substantial effect, the multi-threaded screw structure is described as a two-row screw structure for simplicity.

A key feature of the present invention in relation to the 'multi-threaded structure' is that each thread (first screw thread 211, first thread of the male thread portion 11 of the first case 10 or the female thread portion 21 of the second case 20) The

starting points

211a and 212a of the two screw threads 212 are shifted from each other.

The above features will be described in more detail below. (For convenience of description or to avoid the hassle of overlapping description, the description of specifying that the female screw portion 21 of the second case 20 is made of multi-threaded screws will be described above. have.)

Looking at the female screw portion 21 of the second case 20 with reference to Figure 4, the female screw portion 21 is a two-threaded screw consisting of the first screw thread 211 and the second screw thread 212, in particular the first screw thread ( It can be confirmed that the starting point 211a of 211 and the starting point 212a of the second screw thread 212 are shifted.

In addition, it is more preferable that the starting point 211a of the first screw thread 211 and the starting point 212a of the second screw thread 212 form 180 ° with each other.

The female threaded portion 21 of the second case 20, which is composed of two rows of first and

second screw threads

211 and 212 having

misaligned starting points

211a and 212a, is a starting point for coupling the male threaded portion 11 ( The first case 10 and the

second screw thread

211, 212a may be selected as either the starting point (211a) (212a) of the first and the second screw thread (211) (212a) because the first case 10 and the first The combination of two cases 20 is made.

In addition, in the process of coupling or releasing the first case 10 and the second case 20 of the present cosmetic container (C) by rotating only 90 ˚ that the coupling or decoupling, as described above 'multiline screw Structure ', which allows the user to be simultaneously provided with two effects on the mutual benefits of' tightness of coupling 'and' ease of coupling '.

Next, according to another feature of the present invention, the first or second loosening prevention portion 23 made of protrusions is characterized in that it is formed on the overlapping portion 30 raised from the thread forming surface.

1 and 3, the head portion 30 is formed in the overlapping portion 15 of the first case 10, and the first release preventing portion 13 is formed on the head portion 30. Although shown, this is only a kind of embodiment, it is also possible to form the head portion 30 on the inner surface of the second case 20, the first loosening prevention portion 13 and the second loosening prevention portion 23 Is preferably formed on at least the thick portion (30).

Because the first and second

anti-loosening portions

13 and 23 are mutually coupled to each other by protrusions or annular grooves, the coupling portions of the first and second

anti-loosening portions

13 and 23 are at least inward of the outer boundary of the first and

second cases

10 and 20. It is because it is preferable to form.

Due to the stub portion 30, the cosmetic container (C) in the coupling between the first and the

second case

10, 20, the more airtightness is increased and the waterproofness against the penetration of external dust, moisture, etc. Have

Next, in Figures 1 to 3 it can be seen that the idle prevention projection 50 is formed around the end of the opening of the second case 20.

The injection molding method of supplying the raw material to the extrusion molding machine and extruding it from the mold may be used by injection molding the cosmetic container (C). At this time, in order to form a screw thread inwardly as in the second case 20, a core is inserted and the core is turned to form a screw thread. In addition, at this time, the idle prevention projection 50 allows the core to form a thread accurately without turning.

However, the idle prevention projection 50 has another effect, the gripping portion 16 of the first case 10 is larger than the overlapping portion 15 is a natural considering the structure of the coupling, this wave The stepped part 17 is formed in the boundary part of the branch part 16 and the overlap part 15.

The periphery of the opening end of the second case 20 provided with the anti-rotation protrusion 50 is in close contact with the stepped portion 17. The frictional force generated at the contact portion is a feeling of detachment of the product (first and second cases ( 10) the sensitivity of the user when engaging and disengaging (20) may be lowered.

Therefore, the idle prevention projection 50 acts as a friction damping slit to reduce the friction between the periphery of the opening end of the second case 20 and the stepped portion 17, thereby improving the user's detachment.

In the above description of the present invention with reference to the accompanying drawings, the cosmetic container (C) having a specific shape and structure was described mainly, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, such modifications, changes and Substitutions should be construed as falling within the protection scope of the present invention.
