Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, a cosmetic refill case 100 according to the present invention includes a compact outer container, more specifically, a lower body 12, a body 14 and an upper body 16 And is mounted inside the outer container 10 constituted. More preferably, in a refill type inside the inner body 14 of the outer container 10.

The cosmetics 20 contained in the cosmetics refill case 100 are pressed against the elastomeric support outlet panel 50 using the makeup tools 30 such as puffs, So that it can be used.

Next, the cosmetic refill case 100 according to the present invention will be described with reference to Figs. 2 and 3. Fig.

According to the present invention, the cosmetic refill case 100 includes an internal body 112 formed so that the cosmetic receiving space 111 in which the cosmetic 20 is contained is opened to one side, A main body 110 including an outer support 114 and a hinge 130 provided on one side and the other side of the outer support and a cover 120 opened and closed unilaterally through the configuration of the lock 132, Wherein the inner body 112 and the outer support 114 are connected and supported by a stretchable and contractible portion 116 having an elastic contact portion 117 and the lid 120 is provided with an airtight seal And the ribs 122 are provided so that the expansion and contraction portion 116 is forced to be expanded and contracted by the airtight rib 122 when the lid is opened and closed.

The elastic contact portion 117 of the elastic portion 116 is formed in an upwardly curved shape and the airtight groove 123 is formed in the airtight rib 122 so as to correspond to the contact portion.

The upwardly bending elastic contact portion 117 acts in such a state that the airtight rib 122 of the lid 120 is opened to the outside at the time of forced contact so that the airtight groove 123 of the airtight rib They are in close contact with each other.

When the lid 120 is closed, the first and the second supporting walls 118 and 118 are formed on the upper and lower surfaces of the elastic member 122, As shown in Fig.

The upper end inner peripheral surface of the first support wall 118 is formed as a tapered surface 118a so that the airtight rib 122 can be easily inserted when the lid 120 is closed.

2, when the lid 120 is closed, the airtight rib 122 is elastically deformed by the stretchable and contractible portion 116. As a result, when the lid 120 is closed as shown in FIG. 2 in the state where the elastic contact portion 117 of the stretchable and contractible portion 116 is bent upward, And the airtight grooves 123 formed in the airtight ribs are formed at the same positions as the unspecified portions of the elastic contact portions 117 and the airtight grooves 123 formed in the airtight ribs. The airtight rib 122 of the lid 120 separates from the stretchable portion 116 when the lid 120 is separated from the stretchable portion 116 as shown in FIG.

At this time, the expansion and contraction of the stretchable and contractible portion 116 will exert a side effect that the outer support 114 is more closely attached to the middle body 14 (see FIG. 1).

When the lid 120 is opened, the airtight rib 122 is detached from the elastic contact portion 117, so that the pressing force against the elastic contact portion is canceled, so that the elastic contact portion in the extended state is restored to its original state by its own elastic force.

Therefore, according to the present invention, since the expansion and contraction of the expansion and contraction portion 116 as described above causes the internal gas 112 to be more tightly sealed in the closed state of the lid 120, There is no problem such as deterioration of the cosmetics, drying and leakage due to the inflow of air, and it is possible to use the cosmetics hygienically while maintaining the quality of the cosmetics for a long time.

In the meantime, according to the present invention, the elastic contact portion 117 of the stretchable and contractible portion 116 may be formed in the shape of "∨" bent downward as shown in FIG. 4 and FIG.

As described above, the upwardly bending elastic contact portion 117 of the shape of 'V' acts in such a state that the airtight rib 122 of the lid 120 is held inward during forced contact, so that at least one of the airtight ribs Can be brought into close contact with each other.

The airtight rib 122 of the cover which is hermetically contacted with the downwardly bent " V " elastic contact portion 117 is further formed with a cutout groove 124 opened to the lower end so as to be elastically coupled. desirable.

A second support wall 119 is formed at an upper portion of the expansion and contraction portion 116 so as to be in close contact with the inner and outer surfaces of the airtight rib 122 when the lid 120 is closed, .

At this time, the inner circumferential surface of each upper end of the second support wall 119 may be formed as a flared surface 119a so that the airtight rib 122 of the lid 120 contacting the upper surface is more easily fitted.

The lid 120 as shown in Fig. 4 is closed so that the airtight rib 122 is elastically deformed by the elasticity of the stretchable and contractible portion 116. As a result, When the contact portion 117 is forcibly press-contacted, at least one or more of the lower surface and the outer surface of the airtight rib are finally brought into forced contact with each other through the action of the open end being forced inwardly to stably airtight. The elastic contact portion 117 is returned to its original position while being widened to the outside.

According to the present invention, the airtight grooves 118b and the airtight protrusions 122b for mutual airtight coupling are further formed in the airtight ribs 122 of the stretchable and contractible portion 116 and the lid 120 coupled thereto Load is preferable. These airtight grooves and airtight protrusions may be formed by mutually changing positions.

Through the airtight groove 118b and the airtight protrusion 122b structure, the lid 120 to be closed to the main body 110 provides a stronger coupling force with the lock portion 132, and at the same time, Thereby providing a high air tightness. Since the expansion and contraction of the stretchable and contractible portion 116 is performed at the same time when the airtight groove and the airtight projection are combined, these engagement and disengagement operations can be performed smoothly and quickly.

Accordingly, the present invention is constructed such that when the cover 120 is opened and closed, the stretchable portion 116 having the elastic contact portion 117 capable of elastic action is connected between the inner body 112 and the outer support 114, The airtight action against the internal gas can be more effectively achieved through the expansion and contraction action of the portion.
