Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic container having an umbrella prevention function,

The present invention relates to a cosmetic container provided with a cosmetic stick having a brush on a cap which is a lid for opening and closing an opening of the container body. In detail, the cosmetic container can not only open and close the cap easily, The present invention is directed to a cosmetic container which is capable of preventing a phenomenon in which the hair of the cosmetic container is tangled or widened.

In general, the cosmetic container comprises a container body having a cylindrical neck, a cap detachably mounted on the end of the neck by the coupling means, and a stick protruding from the interior of the cap and having a brush at its end. The container body is provided with an inlet at the end of its neck, while a liquid cosmetic is stored therein through the container inlet. The engaging means is constituted by a male screw provided on the outer periphery of the neck portion and a female screw provided on the inner periphery of the cap so that the container body and the cap are screwed together.

Thus, when capping the neck, the container inlet is closed and the stick is inserted into the container body. When you want to make up, insert a stick into the body of the container, put the cosmetics on the brush, remove it, and apply the cosmetic on the brush to the desired area. The cosmetics stored in such a cosmetic container may be, for example, lip-gloss, manicure, and the like.

However, such a cosmetic container has the following problems.

Since the engaging means is composed of a female screw and a male screw, there is a difficulty in operating the cap several times in order to engage or disengage the cap body from the cap. In addition, in the process of rotating the cap several times, the bristles to be arranged are tangled or spread apart due to friction with cosmetics (generally having viscosity) or viscosity of cosmetics (Referred to collectively as an umbrella phenomenon) (see FIG. 1) was generated and the cosmetic could not be applied exactly to a desired site.

On the other hand, when looking at the production process, cosmetics are injected into the container body, then the cap is capped by the mechanical device, and since the cap is put on by momentarily applying strong force, It is also a problem that occurs frequently in the production process.

The object of the present invention is to provide a cosmetic container capable of ensuring a further improved convenience in opening and closing operation of a cap and preventing a phenomenon of the brush being wiggled or widened in the process of opening or closing the cap .

According to an embodiment of the present invention, there is provided a container comprising: a container body having a cylindrical neck portion forming a container inlet; A cap covering the neck portion of the container body; And a cosmetic stick which protrudes from the inside of the cap and is inserted into the container body when the cap is put on the neck portion and has a brush at the end thereof, and a plurality of sliding grooves are formed on an outer circumference of the neck portion, And the sliding protrusions are formed on the inner circumference of the cap so that the sliding protrusions can be respectively inserted into the sliding recesses. One end of each of the sliding recesses is in communication with the end of the neck portion, Shaped curved portion which is curved at a predetermined angle in the outer circumferential direction of the neck portion so as to be curved in a direction opposite to the groove entrance so that the other end of the groove is directed in a direction opposite to the groove entrance side; A locking part provided on the other of both ends of the curved part so as to be engaged with a sliding protrusion entering along the curved part; And a connecting portion that connects the curved portion and the engaging portion in a curved manner to guide the movement of the sliding protrusion between the curved portion and the engaging portion. The sliding protrusion is inserted into the sliding groove in the cap, There is provided a cosmetic container having a packing ring which is pressed while being in contact with an end of a part and which retains the engagement between the sliding protrusion and the engaging part by a restoring force.

The grooved inlet may be formed to have a wider width. In this case, the width of the groove inlet may be in a central angle range of 40 to 80 degrees with the center point of the container inlet as a vertex.

The sliding groove may be formed such that the rotation angle of the cap, which is required to engage the sliding protrusion with the engaging portion, is in a range of 30 to 70 degrees.

The slide protrusion may be formed in a circular shape so as to be in point contact with the wall surface of the slide groove.

According to the present invention, a sliding groove is formed on the outer periphery of a neck portion, the sliding groove being formed by a curved portion, a locking portion, a curved portion, and a connecting portion for connecting the curved portion and the locking portion in a curved manner. The inner periphery of the cap is inserted into the sliding groove, A cap is placed on the neck portion so that the sliding protrusion is engaged with the sliding groove, and when the cap is put on the neck portion, the sliding protrusion is engaged with the locking portion to close the cap. When the cap is closed, The cap is opened so that the cap can be conveniently opened and closed without having to rotate the cap multiple times.

In addition, in the present invention, when the cap is opened and closed, only a certain angle (preferably 30 to 70 degrees) can be rotated without rotating the cap several times. Therefore, in the process of opening and closing the cap, It is possible to maintain a state in which they do not become entangled or frayed due to the viscosity of the liquid.

Further, the present invention can provide an improved operation feeling because the curved connecting portion ensures a smooth and smooth movement of the sliding protrusion between the curved portion and the engaging portion.

In the present invention, the packing ring, which maintains the engaged state when the sliding protrusion is engaged with the latching part, is partially released (restored), and is restored to the original shape in the process of opening the cap. The restoring force (the movement of the sliding protrusion is guided smoothly from the latching portion to the curved portion side) is added, and the cap can be opened more easily.

Further, since the packing ring functioning as an elastic body functions as a packing when the cap is closed, the present invention can provide a sealing effect for preventing leakage of cosmetics.

Since the present invention has a structure in which the groove entrance of the sliding groove is extended, the operation for fitting the sliding protrusion into the sliding groove can be carried out easily and quickly without trial and error several times.

2, 3 and 4, the cosmetic container according to the present invention comprises a container body 10 provided with a neck part 14 on its upper part, And a cosmetic stick 42 protruding outward from the inside of the cap 20 and provided with a brush 44 at an end thereof.

The neck portion 14 forming the container inlet 12 of the container body 10 is formed into a cylindrical shape in the vertical direction and a liquid cosmetic such as lip gloss or manicure is inserted through the container inlet 12 . When the neck portion 14 is covered with the cap 20, the stick 42 is inserted into the container body 10 together with the brush 44.

The coupling means 30 is adapted to naturally engage the cap 20 with the neck 14 in the process of covering the neck 20 with the cap 20, A plurality of sliding grooves 32 provided at equal intervals so as to be spaced from each other along the outer circumferential direction of the portion 14 and sliding protrusions 34 provided inside the cap 20 so as to be fitted in the plurality of sliding grooves 32 ).

5 is a front view showing the neck portion 14, and shows the structure of the sliding groove 32. As shown in Fig. 5, each of the sliding grooves 32 includes a curved portion 32A into which the sliding protrusion 34 is fitted, a sliding protrusion 34 which is fitted in the curved portion 32A and enters along the curved portion 32A, And a connecting portion 32D for connecting the engaging portion 32C and the curved portion 32A so that the engaging portion 32C and the curved portion 32A are connected to each other.

The curved portion 32A is wound at a certain angle in the circumferential direction of the neck portion 14 so that both ends of the curved portion 32A face the upper end side and the lower end side of the neck portion 14, (Curved) shape. The upper end of the curved portion 32A at the end of the neck portion 14 communicates with the end of the neck portion 14 so that the curved portion 32A is slidably opened And a groove inlet 32B at which protrusion 34 starts to be fitted.

The engaging portion 32C is engaged with a sliding protrusion 34 which enters the curved portion 32A along the curved portion 32A at the lower end side (toward the end opposite to the end of the neck portion 14) So as to have a shape that can be seen.

The connecting portion 32D guides the movement of the sliding protrusion 34 so that the sliding protrusion 34 smoothly and smoothly moves between the curved portion 32A and the locking portion 32C. The sliding portion 32A and the locking portion 32C are connected between the locking portion 32C and the locking portion 32C at the curved portion 32A or the sliding portion 32A is moved from the locking portion 32C to the curved portion 32A, And is formed into a curved shape so as to extend the flow (moving force) of the projection 34.

Here, when the lower end side of the curved portion 32A is referred to as a first position, the engaging portion 32C is referred to as a second position, and the connecting portion 32D is referred to as a third position, The protrusion 34 passes through the first position (see FIG. 8A), which is the lower end side of the curved portion 32A, and the second position, which is inside the connection portion 32D (see FIG. 8B) (See (C) in Fig. 8) in which it is engaged with the engaging portion 32C. And the sliding groove 32 is formed so that the first position is located on the upper side of the neck portion 14 than the second position and the third position is located between the first position and the second position.

The groove inlet 32B is formed so as to have an expanded width so as to easily insert the sliding protrusion 34. [

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

The engaging means 30 further includes a packing ring 36 for holding the sliding protrusion 34 in the engaged state with the engaging portion 32C of the sliding groove 32. [ The packing ring 36 is pressed while being in contact with the end of the neck portion 14 as the sliding protrusion 34 fitted in the curved portion 32A moves toward the connecting portion 32D and enters the connecting portion 32D to move the sliding protrusion 34 (The sliding projection 34 is engaged) between the first position (the lower end side of the curved portion 32A) and the second position (the inside of the connecting portion 32D) when the engaging portion 32C is further engaged, (The position where the cap 32C is engaged with the cap 32C).

The sliding groove 32 starts to contact the end of the neck portion 14 when the sliding ring 34 is in the first position and the packing ring 36 is in contact with the end of the neck portion 14, When the sliding protrusion 34 is located at the second position, the packing ring 36 is compressed. When the sliding protrusion 34 is located at the third position, the compressed packing ring 36 is partially recovered.

The sliding protrusion 34 is engaged with the sliding groove 32 as follows.

The neck portion 14 is covered with the cap 20 so that the sliding protrusion 34 is inserted into the sliding groove 32. [ Then, the sliding protrusion 34 fitted in the sliding groove 32 enters the first position while drawing a curved trajectory curving along the curved portion 32A, and the packing ring 36 contacts the neck portion 14 (See Fig. 8 (A)).

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 smoothly and smoothly moves toward the latching portion 32C side by the guiding action of the curved connecting portion 32D, and is engaged with the latching portion 32C (refer to FIG. 8B) 8 (C)). In this process, the packing ring 36 is squeezed via the second position as the sliding protrusion 34 passes through the connecting portion 32D as shown in Fig. 8 (B) , When the sliding protrusion 34 is engaged with the locking portion 32C as shown in FIG. 8C, when it is positioned at the third position, it is partially restored by the self-elastic force. At this time, the packing ring 36 functions as a packing for preventing leakage of the cosmetics stored in the container body 10 between the end of the neck portion 14 and the cap 20, and at the same time, And the sliding protrusion 34 is brought into close contact with the engaging portion 32C so as to maintain the engaged state of the sliding protrusion 34. [

Here, the user is allowed to make point contact with the sliding contact 32D, the curved connecting portion 32D of the sliding protrusion 34 entering the sliding groove 32 while drawing the arc trace along the curved arc-shaped curved portion 32A The sliding protrusion 34 can smoothly and smoothly move to the locking part 32C side by the circular sliding protrusion 34 which engages with the locking part 32C.

When the engaging portion 32C and the sliding protrusion 34 are to be disengaged from each other, the cap 20 is rotated by a predetermined angle so that the sliding protrusion 34 engaged with the engaging portion 32C is moved toward the connecting portion 32D do. At this time, the sliding protrusion 34 smoothly and smoothly moves toward the curved portion 32A along the curved connecting portion 32D. In this process, the packing ring 36, It moves more smoothly toward the curved portion 32A side without requiring a force.

As described above, since the cap 20 is opened or closed when the cap 20 is rotated at a predetermined angle without rotating the cap 20 several times, the degree of friction between the brush of the brush 20 and the 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 range of the central angle? 1 of 40 to 80 degrees with the center point of the container inlet 12 as the vertex. As shown in Fig. 7, the sliding groove 32 has a rotation angle [alpha] 2 of the cap 20 necessary for engaging the sliding protrusion 34 with the locking portion 32C in the range of 30 to 70 degrees .

For example, when the two sliding grooves 32 are equally spaced along the circumferential direction of the neck portion 14 and the central angle? 1 is 40 degrees (or 80 degrees) The cap 20 can be rotated 70 degrees (or 50 degrees maximum) to the left or right so that the sliding protrusion 34 can be inserted into the sliding groove 32, respectively. When the central angle? 1 is less than 40 degrees, the maximum rotation angle of the cap 20, which must be rotated in order to fit the sliding protrusion 34 into the sliding groove 32, is large. On the other hand, when the central angle? 1 is more than 80 degrees, it is difficult to process and it is required to secure a wide space for forming the extended structure of the groove entrance 32B.

The smaller the rotation angle? 2, the faster the cap 20 can be opened and closed. However, since a large force (operation force) is required instantaneously for the operation, the minimum rotation angle? 2 is preferably 30 degrees. On the other hand, when the rotation angle? 2 exceeds 70 degrees, the cap 20 is wasted relatively long in opening and closing the cap 20, which is not preferable from the viewpoint of operability. That is, when the rotation angle? 2 exceeds 70 degrees, there is no significant difference in the operation force (torque) as compared with the case where the rotation angle? 2 is 70 degrees, but a difference occurs in terms of time.

The following table shows the results of the survey conducted on this design. The questionnaire survey was conducted to confirm satisfaction with the operability (operation feeling, operation torque) of the cap 20, and the cap 20 was closed to 20 persons in 20 to 40 women, , And satisfaction with operability.

Satisfaction was evaluated from 5 points to 1 point, 5 points were very satisfied, 4 points were satisfied, 3 points were normal, 2 points were dissatisfied, and 1 point was highly unsatisfactory.

In the embodiment and the comparative example, the central angle? 1 and the rotation angle? 2 are different from each other, except that the two sliding grooves 32 are equally spaced along the circumferential direction of the neck portion 14, same.

1) Example 1: central angle? 1 = 60 degrees, rotation angle? 2 = 60 degrees

2) Embodiment 2: central angle? 1 = 45 degrees, rotation angle? 2 = 35 degrees

3) Example 3: central angle? 1 = 45 degrees, rotation angle? 2 = 65 degrees

4) Example 4: central angle? 1 = 75 degrees, rotation angle? 2 = 65 degrees

5) Comparative Example 1: central angle? 1 = 30 degrees, rotation angle? 2 = 60 degrees

As a result of the survey, when the width of the groove entrance 32B is out of the range of the central angle? 1 and the rotation angle of the cap 20 is out of the range of? 2, the operability of the cap 20 is bad. In particular, in Comparative Example 4, the operability was worse than in Comparative Examples 1 to 3. This is because the comparative example 4 has a curved arcuate curved portion 32A, a grooved inlet 32B whose width is widened, The connection portion 32D and the like are not provided.

Although the present invention has been described in detail, it is to be understood that the present invention is not limited to the disclosed embodiments and accompanying drawings, and various modifications may be made by those skilled in the art without departing from the technical idea of the present invention.
