In general, in the compact of cosmetics, the contents provided in the form of solid powder are stored inside the lower case, and the upper case is opened and closed in the lower case, but the cosmetics are applied to the face using a separate puff (puff). To use.

The contents of such cosmetics are manufactured in various ways, and in particular, the contents contained in the compact are made of a solid powder containing moisture or volatile substances.

If the sealing power of the cosmetic case is poor, external air flows into the case, causing the moisture or volatile substances contained in the contents to evaporate, causing the contents to harden and lose its original function. Therefore, since the case for storing the contents requires sealing force to prevent the contents from being deteriorated by blocking the inflow of external air, various types of sealed cases are being released.

In addition, not only the function of blocking the inflow of external air in the closed state, but also the function of discharging the internal air as much as possible when closing the case is required because air remains inside and the contents change after a certain period of time when the case is closed after using cosmetics. have.

Recently, as the sales volume of expensive cosmetics increases, the importance of a sealed case that can safely store the contents for a long period without alteration is increasing. Factors that cause deterioration and contamination of cosmetic contents include air and external environments (temperature, humidity, bacteria, dust, etc.). In addition, product releases of functional contents with a high moisture content and complex functions are rapidly increasing in recent years.

Accordingly, the demand for a cosmetic container having an air-tight function that prevents deterioration of the cosmetic contents, that is, an airtight case for blocking air inflow and minimizing residual air during sealing, continues to increase.

8 is a cross-sectional view (Fig. 3 (a) A-A) and a partial enlarged view of the front view showing a state in which the upper cover of the case having a sealing function according to an embodiment of the present invention is closed.

A process of sealing the inner space 140 by a case having a sealing function according to an embodiment of the present invention will be described with reference to FIG. 8 as follows.

In order to seal the case after opening the upper cover 200 to use the contents, the user rotates the upper cover 200 along a hinge axis to be coupled to the lower container 100. The first rib 220 of the upper cover 200 comes into contact with the protrusion 120 of the lower container 100 first, and when the upper cover 200 is pressed, the first rib 220 As it is inserted between the outer wall and the protrusion 120, the protrusion 120 is pressed in the direction of the inner space 140. In this process, the internal air remaining in the internal space 140 may be continuously discharged to the outside.

When the upper cover 200 is continuously pressed, the second rib 230 comes into contact with the protrusion 120, and the second rib 230 is gently forced into the groove between the protrusion 120 and the inner wall 130 of the lower container. While being able to combine.

While the first rib 220 and the second rib 230 are unevenly coupled with the protrusion 120, the inlet of the case is not completely sealed, so the air remaining in the inner space 140 will continue to flow out to the outside. I can.

The upper end of the protrusion 120 may be formed as an inclined surface 121 inclined toward the outer wall 110 of the lower container. When the upper cover 200 is closed, the first rib 220 can be prevented from being caught on the protrusion 120 by the inclined surface 121 to smooth the contact.

The sealing structure of the present invention minimizes the compression of the air remaining in the inner space 140 when the upper cover 200 is closed, so that the upper cover 200 cannot be easily closed due to the compression of the air. Even after completely sealing 200), a problem in which the upper cover 200 is opened again due to the compressed air therein may be solved.

In addition, by minimizing the compression of air in the inner space 140, when the upper cover 200 is closed, the upper cover 200 opens rapidly and the contents are prevented from splashing out even if the user applies a small force to the upper cover 200. can do.

In addition, in order to discharge the air in the inner space 140 as much as possible, the general case must be slowly closed while discharging the inner air when rotating the upper cover 200 around the hinge axis. The space where air can be discharged is sealed last in the sealing process, and the internal air is discharged as much as possible. Therefore, only a minimum amount of air is left in the inner space 140, so that drying and decay of the contents due to the air located in the inner space 140 can be prevented.

When the upper cover 200 is continuously pressed, the first and second ribs 230 are completely unevenly coupled with the protrusion 120, and finally, the fitting member 211 of the upper cover 200 dents the lower container 100. It is inserted into the part 112. When the locking member 212 is formed on the inner circumferential surface of the fitting member 211, the locking member 212 is bound to the locking part 111 of the lower container 100 so that it can be more firmly connected.

In addition, the first rib 220 may be formed along the inner circumferential surface of the upper cover 200 and may have a curved shape 240 in which a portion of the first rib 220 protrudes further downward. The curved shape 240 may be provided on both sides of the upper cover 200.

Since the first rib 220 of the upper cover 200 has a curved shape 240 and is inserted deeper into the lower container 100, it is possible to prevent external air from flowing into the inner space 140 even if a gap occurs. have.

In addition, even if the lower container 100 is deformed, since the curved shape 240 of the first rib is deeply inserted into the lower container 100 to serve as a guide, there is an effect of maintaining the sealing.

9 is an exploded perspective view of a case having a sealing function according to an embodiment of the present invention.

If a liquid in which the contents accommodated in the inner space 140 may flow, a sponge for absorbing cosmetics may be provided in the inner space 140. The diameter of the sponge is formed slightly smaller than the inner diameter of the inner space 140 so that the sponge and the inner space 140 may be spaced apart.

In addition, between the inner circumferential surface of the inner space 140 and the sponge, a retaining ring 300 may be provided having a height higher than the thickness of the sponge and having an upper inner diameter smaller than the diameter of the sponge to prevent separation of the sponge. The fixing ring 300 may be detachably provided in the inner space 140.

Accordingly, the sponge is supported by the upper portion of the fixing ring 300 to prevent separation of the sponge.

The fixing ring 300 may be detachably provided in the inner space 140.

Among conventional products, when the retaining ring 300 is integrally formed with the lower container 100 or the retaining ring 300 is completely fixed to the inner space 140 and inserts a sponge absorbing the contents, the contents are placed around the case. There is a disadvantage that it is not easy to bury or insert a sponge.

However, in this embodiment, since the fixing ring 300 is detachably provided in the inner space 140, the sponge in which the contents are absorbed is first inserted into the inner space 140, and then between the sponge and the inner circumferential surface of the inner space 140 By inserting the fixing ring 300 in the case, the sponge can be easily inserted without burying the contents.

A receiving portion 270 capable of accommodating a cosmetic puff may be formed on an upper surface of the upper cover 200. In addition, a handle 260 may be formed to easily open and close the upper cover 200.
