Description

Airtight ring structure of cosmetic container {AIRTIGH-RING STRUCTURE OF COSMETIC VESSEL}

The present invention relates to a cosmetic container for moisturizing and maintaining the maintenance according to the use of the foundation and color cosmetics, and in particular at the same time the closing operation by the elastic locking between the inner lid assembled in the outer lid and the inner container assembled in the container body Shrinkable airtight ring configured in the liver or the airtight ring between any one of the airtight ring and the inner lid or the inner container end is kept airtight and the airtightness of the outer lid and the elimination of the opening and closing means of safety and manufacturing cost It relates to the structure of the airtight ring of the cosmetic container to reduce and increase the airtightness.

Recently, various basic and color cosmetics have been disclosed, and these basic and color cosmetics have been filled and used in portable cosmetic containers for the purpose of portable storage as well as convenience of use.

As an example, the compact is configured to store and hold the foundation in a cosmetic container molded into a predetermined shape, and to apply the foundation to the face by using a medium such as a puff (puff) during use.

However, the foundation contains a harmless volatile solvent of the human body, and if such a volatile solvent is not properly maintained, there is a problem that the foundation hardens and cannot be used because the foundation is hardened.

In addition, there is a problem that the characteristics of the cosmetics can not be guaranteed for a long time by evaporation of the inherent aromas of the basic and color cosmetics.

For this reason, the base and the cosmetic container has an airtight structure in which the inside is blocked from the outside when the lid is closed to prevent deterioration of the filled cosmetics.

The cosmetic container having the airtight structure has a basic structure of a lower container body, an inner container filled in the container body and filled with cosmetics, a puff (puff) selectively received in an upper portion of the inner container, and an upper portion of the container body. The hinge is coupled to one side and the opposite side is composed of an outer lid that is opened and closed while maintaining and releasing the locked state by the lock portion.

In this case, the cosmetics accommodated in the inner container is installed to support the gasket of the elastic rubber material provided separately on the upper portion of the support frame provided to the outer side of the inner container in order to maintain the moisturizing, steering, the outer surface of the gasket when closed It is configured to maintain a mutual airtight so as to constitute a protrusion to press the ribs.

However, the conventional hermetic structure has a problem in that productivity and assembly workability are lowered and manufacturing costs are increased due to a work request such as separately forming and assembling the packing of the elastic rubber material to maintain the airtightness between the inner container and the outside. .

In order to solve this problem, a hermetic cosmetic container as shown in FIG. 1 is disclosed.

That is, as shown in Figure 1a, the injection groove (3a) is formed along the upper side of the support body (3) provided outside the inner container (5) of the container body (2), the liquid rubber into the injection groove (3a) By filling and hardening the airtight hardened rubber (4) to be closed by the push button (7) of the lock part when the outer lid (6) is closed, the closed state is maintained and integrally formed on the bottom of the outer lid (6). The ribs 6a were brought into close contact with the cured rubber 4 to maintain airtightness.

Such a technology has advantages of doubling airtightness by a simple structure by using liquid rubber and of filling and curing the hardened rubber, thereby improving productivity and assembly workability and reducing manufacturing cost.

This source technology, as shown in the enlarged view of Figure 1b, the cured rubber 4 is cured in a state that the central portion is concavely reduced by the surface tension at the time of curing the liquid rubber is first injected, the surface The rib 6a in contact is provided with a hard plastic protrusion having a higher strength than the hardened rubber 4 so that the hardened rubber 4 is kept tightly compressed in the closed state of the outer lid to be hermetically sealed.

However, the hardened rubber 4 in the state of being pressed by the ribs 6a is deformed (destructed) in fatigue strength (fatigue strength) in which the pressed state is not properly restored even when the pressed state is released by the opening of the outer lid. As shown in Figure 1c, the hardened rubber grooves (groove: 4a) is formed, the deformation is extended by the pressing contact of the repetitive ribs (6a) according to long-term use is not sure close contact with each other is not properly sealed. It is pointed out that the product reliability is poor.

In addition, the rib 6a integrally protruded and formed at the bottom of the outer lid 6 has a non-uniform contact end surface of the rib 6a due to torsional deformation caused by a temperature change after molding, thereby further reducing airtightness characteristics. It is pointed out as a factor.

Therefore, the applicant has filed a Korean patent application No. 10-2010-24340 (airtight ring structure of the cosmetic container).

This applicant's source technology is to combine the container body to accommodate the inner container filled with cosmetics, and to form a hardened rubber by filling and curing the liquid rubber in the injection groove formed on the upper side, one side hinged to the container body The hardened ribs, which are coupled to each other and provided with a lock portion capable of maintaining and releasing the locked state on the opposite side thereof, open or close the inner container and seal the storage space of the inner container in close contact with the hardened rubber on the bottom thereof. It consists of an outer lid molded from rubber and different elastomers.

The applicant's source technology is to form a rib in close contact with the hardened hardened rubber with a different type of elastic material for the purpose of airtightness, and the deformation is canceled even under coercive contact, thereby maximizing the airtightness by preventing the deformation of fatigue strength. There is an advantage to increase.

In addition, Korean Utility Model Registration No. 20-0388703 (cream-type storage container for cosmetics) is also disclosed.
