As shown in Figures 2, 3 and 4, the cosmetic container according to the present invention is the end of the neck portion 14 by the container body 10, the coupling means 30 is provided with a neck portion 14 at the top (top) The cap 20 is detachably covered with a), and a cosmetic stick 42 protruding from the inside of the cap 20 to the outside and having a brush 44 at the end thereof.

The container body 10 has a neck portion 14 forming the container inlet 12 in a cylindrical shape in the vertical direction, while the liquid cosmetics such as lip gloss or nail polish are introduced through the container inlet 12. Stored. When the cap 20 is closed by closing the neck portion 14, the stick 42 is inserted into the container body 10 together with the brush 44.

Coupling means 30 is configured to naturally couple the cap 20 to the neck portion 14 in the process of covering the cap 20 to the neck portion 14, the neck on the outer circumference of the neck portion 14 A plurality of sliding grooves 32 provided at equal intervals so as to be spaced apart from each other along the outer circumferential direction of the portion 14, the sliding projections 34 provided in the interior of the cap 20 to be fitted into the plurality of sliding grooves 32, respectively. ).

5 is a front view showing the neck portion 14, showing the configuration of the sliding groove (32). As shown in FIG. 5, each sliding groove 32 has a curved portion 32A into which the sliding protrusion 34 is fitted, and a sliding protrusion fitted into the curved portion 32A and entering along the curved portion 32A. A locking portion 32C to which the 34 is engaged, and a connecting portion 32D for connecting the locking portion 32C and the curved portion 32A to be connected to each other.

The curved portion 32A is wound at a constant angle in the circumferential direction of the neck portion 14 such that both ends thereof face the upper side and the lower side of the neck portion 14, respectively, and are curved toward the lower side of the neck portion 14. It is formed into an inclined arc (curve) shape. The upper end (the side facing the end of the neck portion 14) of both ends of the curved portion 32A communicates with the end of the neck portion 14, so that the curved portion 32A slides the open upper portion as it communicates. It is set as the groove inlet 32B where the projection 34 starts to fit.

The engaging portion 32C may be engaged with the sliding protrusion 34 entering along the curved portion 32A on the lower side of the curved portion 32A (the end side facing away from the end of the neck portion 14). It is provided to have a shape that can be.

The connecting portion 32D guides the movement of the sliding protrusion 34 so that the sliding protrusion 34 can smoothly and naturally move between the curved portion 32A and the locking portion 32C, and the curved portion 32A and the locking portion The curved portion 32A and the locking portion 32C are connected between the 32C, but the sliding portion 32A is moved from the curved portion 32A to the locking portion 32C or the locking portion 32C to the curved portion 32A. It is formed in a curved shape so as to continue the flow (moving force) of the projection (34).

Here, when the lower end side of the curved portion 32A is the first position, the locking portion 32C is the second position, and the connecting portion 32D is the third position, the sliding that fits into such a sliding groove 32 is entered. The projection 34 passes through the first position (see FIG. 8A), which is the lower end side of the curved portion 32A, and the second position (see FIG. 8B), which is inside the connecting portion 32D, in turn. It is located in the third position (see FIG. 8C) that is engaged with the locking portion (32C). In addition, the sliding groove 32 is formed such that the first position is positioned above the second end of the neck portion 14 rather than the second position, and the third position is located between the first position and the second position.

The groove inlet 32B is formed to have a structure in which the width thereof is expanded so that the sliding protrusion 34 can be easily fitted.

The sliding protrusion 34 is formed in a circular shape to make point contact with the wall surface of the curved portion 32A, the locking portion 32C, and the connecting portion 32D constituting the slide groove 32.

Coupling means 30 further includes a packing ring (36) for maintaining the state in which the sliding projection 34 is engaged with the locking portion (32C) of the sliding groove (32). The packing ring 36 is compressed while being in contact with the end of the neck portion 14 by moving and entering the sliding protrusion 34 fitted into the curved portion 32A toward the connecting portion 32D, and then sliding the sliding protrusion 34. When entering further, when engaging the locking portion 32C, the third position (sliding protrusion 34) is caught between the first position (lower side of the curved portion 32A) and the second position (inside the connecting portion 32D). The position engaged with the portion 32C) is mounted inside the cap 20 so as to be partially restored.

In order for the packing ring 36 to act in this way, the sliding groove 32 starts to contact the packing ring 36 with the end of the neck portion 14 when the sliding protrusion 34 is located in the first position, When the sliding protrusion 34 is positioned at the second position, the packing ring 36 is compressed, and when the sliding protrusion 34 is positioned at the third position, the compressed packing ring 36 is partially restored.

The sliding protrusion 34 is coupled to the sliding groove 32 as follows.

The cap 20 is fitted to the neck portion 14 so that the sliding protrusion 34 is fitted into the sliding groove 32. Then, the sliding protrusion 34 fitted in the sliding groove 32 is positioned in the first position, entering the curved trajectory along the curved portion 32A, and the packing ring 36 is located at the neck portion 14. ) Is in contact with the end (see FIG. 8A).

Next, the cap 20 is rotated in the direction in which the sliding protrusion 34 has entered along the curved portion 32A. Then, the sliding protrusion 34 is smoothly and naturally moves toward the locking portion 32C side according to the guide action of the curved connecting portion 32D (see FIG. 8B) and is engaged with the locking portion 32C. In this process, the packing ring 36 is compressed while passing through the second position as the sliding protrusion 34 passes through the connecting portion 32D, as shown in FIG. As shown in FIG. 8C, when the sliding protrusion 34 is positioned at the third position as the sliding protrusion 34 is engaged with the locking portion 32C, the sliding protrusion 34 is partially restored by its own elastic force. At this time, the packing ring 36 functions as a packing for preventing leakage of cosmetics stored in the container body 10 between the end of the neck portion 14 and the cap 20, and at the same time, the cap 20 with its own restoring force. ) To keep the engagement state of the sliding projection 34 by keeping the sliding projection 34 in close contact with the engaging portion 32C by separating the neck 14.

Here, the user makes a point contact with the acceleration force of the sliding projection 34, the curved connecting portion 32D, the sliding groove 32, and entering the arc trajectory along the curved arc-shaped curved portion 32A. The sliding protrusion 34 may be smoothly and naturally moved to the engaging portion 32C by the circular sliding protrusion 34 to engage the engaging portion 32C.

When releasing the engagement between the locking portion 32C and the sliding protrusion 34, the cap 20 is rotated at an angle so that the sliding protrusion 34 engaged with the locking portion 32C is moved toward the connection portion 32D. do. At this time, the sliding protrusion 34 moves smoothly and naturally toward the curved portion 32A along the curved connecting portion 32D. In this process, the compressed packing ring 36 is restored to its original shape by a large force. It moves more naturally to the curved portion 32A side without requiring force.

As described above, the present invention does not rotate the cap 20 several times, the rotation of a certain angle, so that the cap 20 is opened or closed, so the degree of friction between the brush hair and cosmetics generated in the process of opening and closing the cap 20 Can be significantly reduced.

As shown in FIG. 6, the width of the groove inlet 32B is formed to be in the center angle α1 of 40 to 80 degrees with the center point of the container inlet 12 as a vertex. As shown in FIG. 7, the sliding groove 32 has a rotation angle α2 of the cap 20 required to engage the sliding protrusion 34 to engage with the locking portion 32C in a range of 30 to 70 degrees. So that it is formed.

For example, when two sliding grooves 32 are provided at equal intervals along the outer circumferential direction of the neck portion 14, and the center angle α1 is 40 degrees (or 80 degrees), the end of the neck portion 14 When the cap 20 is rotated up to 70 degrees (or up to 50 degrees) to the left or the right while covering the cap 20, the sliding protrusions 34 may be fitted into the sliding grooves 32, respectively. When the center angle α1 is less than 40 degrees, the maximum rotation angle of the cap 20 to be rotated in order to fit the sliding protrusion 34 into the sliding groove 32 is large, which is inconvenient. On the contrary, when the center angle α1 exceeds 80 degrees, processing is difficult, and a large space for securing the expansion structure of the groove inlet 32B is required.

The smaller the rotation angle α2 is, the faster the opening and closing of the cap 20 is possible. However, since the moment requires a large force (operation force) for the moment, the minimum rotation angle α2 is preferably 30 degrees. On the other hand, when the rotation angle α2 exceeds 70 degrees, a relatively large amount of time is spent in opening and closing the cap 20, and thus it may not be good in terms of operability. That is, when the rotation angle α2 exceeds 70 degrees, there is no significant difference in terms of operating force (torque) compared with the case where the rotation angle α2 is 70 degrees, but a difference occurs in terms of time.

The following table shows the results of the survey conducted on the present invention. The questionnaire was conducted to confirm the satisfaction with the operability (operation feeling, operation torque) of the cap 20. After opening and closing the cap 20 to 20 women in their 20s and 40s, the main subjects using cosmetics, The satisfaction level of operability was surveyed.

Satisfaction was scored from 5 to 1 point, 5 points are very satisfied, 4 points are satisfied, 3 points are normal, 2 points are dissatisfied, 1 point is dissatisfied.
