Abstract

Disclosed is a cosmetic case in which a body and a cover thereof are integrally formed by a single process with a single mold, respectively, so that the manufacturing cost of the molds and the assembling cost can be reduced, thereby improving the economical efficiency. The cover can be softly and freely opened and closed by one touch. Further, the cosmetic case can be safely and firmly sealed so that the cosmetic in the case can be prevented from being volatilized, thereby maintaining the original function of the cosmetic.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Korean Patent Application No. 10-2006-0012456, filed on Feb. 9, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

Field of the Invention

The present invention relates to a cosmetic case which can reduce the manufacturing cost by integrally forming a body and a cover thereof by a single process with a single mold, respectively, which can easily open and close the cover by one touch, and which can safely maintain and keep the contents.
Conventionally, since a body and a cover of a cosmetic case have been manufactured by using a plurality of parts which are formed by complex processes which need a plurality of molds, the manufacturing cost of the molds and the assembling cost of the parts have been high.
Further, although some conventional cosmetic cases can be automatically opened, a sealing structure of a packing portion making contact with the peripheral portion of the upper end of the body in which a cosmetic is contained is so vulnerable that the alcohol component in the cosmetic may be volatilized, thereby deteriorating the original function of the cosmetic.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a cosmetic case which can reduce the manufacturing cost by integrally forming a body and a cover thereof by a single process with a single mold, respectively, and which can safely and firmly seal the cosmetic case by using the sealing structure of a plate-like annular packing interposed in the cover making contact with the peripheral portion of the upper end of the body so that a cosmetic therein is prevented from being volatilized and the original function of the cosmetic can be maintained.

BRIEF DESCRIPTION OF THE DRAWINGS

The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a perspective view for showing a cosmetic case according to the present invention, with a cover opened;

FIG. 2 is a cross-sectional view of FIG. 1;

FIG. 3 is a rear view for showing shaft support portions of a body and a cover of a cosmetic case according to the present invention;

FIG. 4 is a cross-sectional view for showing a cosmetic case according to the present invention, with a case closed; and

FIG. 5 is a cross-sectional view for describing the operation for opening a cover of a cosmetic case according to the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Hereinafter, a preferred embodiment of a leftover food-treating device according to the present invention will be described with reference to the accompanying drawings.
A body 1 and a cover 2 are formed by a single process with one mold (not shown), respectively. An upper end protruding wall 3 protrudes from a peripheral portion of the upper end of the peripheral wall 1 a forming the body. A space portion 4 is formed on the front side of the outer peripheral wall of the body. A pressure applying piece 6, from which an outward locking boss 5 protrudes, is integrally formed with the body 1.
Shaft support holes 7 and 7 a are formed on the rear side of the outer peripheral wall of the body 1. Further, a shaft receiving recess 8 is formed on the rear side of the outer peripheral wall of the body 1.
An inner race protrusion 9 protrudes from an inner lower end portion of the peripheral wall 2 a forming the cover 2 so as to define an inner race groove 10. A resilient plate-like annular packing 11 is interposed in the inner race groove 10. A downward support member 12 integrally formed with the peripheral wall 2 a of the cover 2 is formed on the rear side of the cover 2. A shaft receiving portion 12 a is formed at an lower end portion of the downward support member 12, by forming a shaft pin hole 13 a into which a shaft pin 13 is inserted. A locking piece 15, from which an inward locking boss 14 protrudes, is integrally formed with the peripheral wall 2 a of the case 2 on the front side of the cover 2.
A shaft receiving portion 12 a formed at a lower end portion of the downward support member 12 of the cover 2, which is formed by a single mold, is interposed in a shaft receiving recess 8 formed on the rear side of the outer peripheral wall of the body 2. The shaft pin hole 13 a of the shaft receiving portion 12 a is arranged so as to be side by side with the shaft support holes 7 and 7 a formed to both sides of the shaft receiving recess 8, and a shaft pin 13 is inserted into one of the shaft support holes 7 and 7 a and then the shaft pin hole 13 a and the other of the shaft support holes 7 and 7 a. Thereafter, by rotating the cover 2 to the upper side of the body 1, the locking piece 15 formed on the front side of the cover 2 is moved toward the upper end of the pressure applying piece 6 formed on the front side of the outer peripheral wall of the body 1 and thus the inward locking boss 14 inwardly protruding from the locking piece 15 of the cover 2 inwardly applies a pressure to the outward locking boss 5 protruding from the pressure applying piece 6 of the body 2 so that the inward and outward locking bosses 14 and 5 are engaged with each other and the plate-like annular packing 11 interposed in the inner race groove 10 of the cover 2 applies a pressure to the upper end protruding wall 3 formed at the peripheral portion of the upper end of the body. Therefore, the cover 2 can safely and firmly cover the upper end of the body 1.
On the other hand, if a pressure is inwardly applied to the pressure applying piece 6 of the body 1 to open the cover 2, the pressure applying piece 6 is urged to the inner side of the space portion 4 and the inward locking boss 14 of the cover 2, which is engaged with the outward locking boss 5, is released so that the cover 2 can be opened softly and freely.
The cover 2 can be softly and freely opened and closed by one touch, with a cosmetic received in the body 1. Further, since the upper end protruding wall of the body 1 is safely and firmly closed by the resilient plate-like annular packing of wide sealing area, an alcohol component of the cosmetic can be perfectly prevented from being volatilized, with the original function of the cosmetic being safely maintained.
According to the present invention, since the body and the cover are manufactured by a single process with one mold so as to have a single body, respectively, the manufacturing cost of the molds can be remarkably reduced. Further, since the shaft receiving portion, which is formed of a same material so as to have a single structure, is interposed in the shaft receiving recess of the body by inserting only one shaft pin into the shaft receiving portion in order to assemble the cover with the body, the manufacturing cost of the cosmetic case can be remarkably reduced, thereby improving the economical efficiency. Furthermore, since the cover is opened and closed by one touch, the cosmetic case can be simply and easily used and treated. Furthermore, since the cosmetic is efficiently sealed in the cosmetic case, the cosmetic can be prevented from being volatilized, thereby maintaining the original function of the cosmetic so that the cosmetic can be used in a fresh state.
Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
