DETAILED DESCRIPTION OF THE INVENTION

(11) Hereinbelow, an exemplary embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

(12) A refill case for a cosmetic compact 100 (hereinafter, referred to briefly as a refill case) according to an embodiment of the present invention is configured, as shown in FIG. 1, to be mounted in a lower case 12 of a cosmetic compact 10 with an upper case 11 hinged to the lower case, and when cosmetic stored therein is used up, the refill case is separated and discarded and replaced with a new refill case 100. The refill case 100 is detachably accommodated in an accommodation space 12a of the lower case 12.

(13) As shown in FIGS. 1 to 3, the refill case 100 includes: a main body 110 with an upper portion thereof being open; and a case cover 120 rotatably coupled to the main body 110 to seal or uncover the same.

(14) An accommodation space S in the main body 110 accommodates a cosmetic, and as an inner cover for covering the accommodation space, a mesh fabric cover 130, a sponge 140, and an auxiliary mesh fabric cover 150 are separately provided. Thereby, the cosmetic in the accommodation space S can be supplied through the auxiliary mesh fabric cover 150, the sponge 140, and the mesh fabric cover 130. In other words, in the state of FIG. 2, when the mesh fabric cover 130 is pressed with a puff (reference numeral 13 in FIG. 1), the cosmetic in the accommodation space S seeps through the auxiliary mesh fabric cover 150, the sponge 140, and the mesh fabric cover 130 to wet the puff 13.

(15) To be specific to a sealing structure of the refill case 100, as shown in FIG. 4, an accommodation groove 111a is formed along an upper surface of an outer wall 111 of the main body 110, and a sealing protrusion 121 accommodated in the accommodation groove 111a is formed on a lower surface of the case cover 120 to correspond to the accommodation groove. Here, a silicone 112 is applied to the accommodation groove 111a, and an elastomer 122 is integrally formed with the sealing protrusion 121, such that when the case cover 120 is closed and the sealing protrusion 121 is accommodated in the accommodation groove 111a, the elastomer 122 is pressed against a surface of the silicone 112 and is brought into close contact therewith, thereby achieving a perfect sealing of the accommodation space S. Application of the elastomer 122 may be achieved by methods such as insert injection and the like.

(16) The main body 110 is provided with an inner wall 113 with a predetermined gap A between the inner wall and the outer wall 111. The accommodation space S is provided inside the inner wall 113. Further, as shown in FIGS. 5 and 6, a cylindrical vertical extension portion 131 of the mesh fabric cover 130 is engaged with the gap A between the inner wall 113 and the outer wall 111.

(17) A rim portion 132 is formed by extending from an upper end of the vertical extension portion 131 by a predetermined width in an inward direction, and a mesh fabric 133 is interposed between an upper surface of the vertical extension portion 131 and a lower surface of the rim portion 132, such that upper and lower surfaces of the mesh fabric are integrally formed by being interposed between the upper end of the vertical extension portion 131 and an outer edge the rim portion 132 along an edge of the mesh fabric. Thereby, the mesh fabric 133 covers an upper portion of the accommodation space S.

(18) Accordingly, a liquid cosmetic accommodated in accommodation space S is discharged outside only through the mesh fabric 133 because the vertical extension portion 131 is tightly engaged with the gap A between the inner wall 113 and the outer wall 111. Thus, it is possible to prevent leakage of cosmetics with a considerable viscosity by using a single mesh fabric cover 130.

(19) Meanwhile, considering liquid cosmetics with a low viscosity, as shown in FIGS. 3 and 6, under the mesh fabric cover 130, the sponge 140 and the auxiliary mesh fabric cover 150 may be further provided. The sponge 140 has a predetermined vertical thickness, is accommodated such that an outer side surface thereof is brought into contact with an inner side surface of the vertical extension portion 131 of the mesh fabric cover 130 along an edge thereof, and in this state, as shown in FIG. 5, covers the accommodation space S from under the mesh fabric 133.

(20) The auxiliary mesh fabric cover 150 provided under the sponge 140 is accommodated such that an outer side surface of an auxiliary rim portion 151 formed along the auxiliary mesh fabric cover is brought into contact with the inner side surface of the vertical extension portion 131 of the mesh fabric cover 130, and an edge of an auxiliary mesh fabric 152 is integrally formed on the lower surface of the auxiliary rim portion 151. Thereby, the auxiliary mesh fabric 152 covers the accommodation space S from under the sponge 140.

(21) In the state of FIG. 6 where the sponge 140 and the auxiliary mesh fabric cover 150 are accommodated in the mesh fabric cover 130 and arranged on top of each other, as shown in FIG. 5, when the vertical extension portion 131 is tightly engaged with the gap (A in FIG. 4) between the inner wall 113 and the outer wall 111, the edge of the sponge 140 and an outer edge of the auxiliary rim portion 151 of the auxiliary mesh fabric cover 150 are locked by being vertically pressed by the upper end of the inner wall 113 and the lower surface of the rim portion 132 of the mesh fabric cover 130.

(22) Accordingly, even if a cosmetic accommodated in the accommodation space S has a low viscosity, it is possible to prevent leakage of the cosmetic by further providing the sponge 140 and the auxiliary mesh fabric cover 150 in addition to the mesh fabric cover 130.

(23) Here, as shown in FIG. 5, the auxiliary mesh fabric 152 and the sponge 140 thereabove directly facing the accommodation space S are spaced apart from each other by a predetermined vertical gap B of the auxiliary rim portion 151, wherein in a space defined by the gap B, the cosmetic in the accommodation space S seeps and is contained, and when the mesh fabric 133 is pressed by a user with the puff (reference numeral 13 in FIG. 1), the cosmetic contained in the gap B serves as priming and thus is easily discharged outside. Accordingly, even in a multilayer structure constituted by the mesh fabric 133, the sponge 140, and the auxiliary mesh fabric 152, it is possible to use cosmetics without inconvenience.

(24) Meanwhile, as shown in FIGS. 5 and 6, the rim portion 132 of mesh fabric cover 130 is configured such that an inner edge thereof is formed to be inclined downward in the inward direction, whereby when the puff (reference numeral 13 in FIG. 1) is pressed, it is possible to realize a soft touch feeling without being caught on a sharp edge.

(25) Further, in FIG. 6, the vertical extension portion 131 of the mesh fabric cover 130 is provided on an inner surface thereof with protruding portions 131a and 131b protruding while being spaced apart from each other by a predetermined vertical gap, and as shown in FIG. 4, the inner wall 113 of the main body 110 is provided with groove portions 113a and 113b spaced apart from each other by a predetermined vertical gap in the radial direction to correspond to the protruding portions.

(26) Accordingly, when the vertical extension portion 131 is engaged with the gap A between the inner wall 113 and the outer wall 111 of the main body 110, the protruding portions 131a and 131b are engaged with the groove portions 113a and 113b respectively, whereby it is possible to improve the coupling strength of the mesh fabric cover 130 to the main body 110.

(27) Here, of the two protruding portions 131a and 131b, the upper protruding portion 131a supports the outer edge of the auxiliary rim portion 151 of the auxiliary mesh fabric cover 150 when the sponge 140 and the auxiliary mesh fabric cover 150 are inserted under the mesh fabric cover 130 as shown in FIG. 6, such that the sponge 140 and the auxiliary mesh fabric cover 150 accommodated in the vertical extension portion 131 are prevented from being separated from the vertical extension portion (see FIG. 5). Thereby, there is an advantage that the assembling process is simplified.

(28) Further, referring to FIGS. 4 and 6, the rim portion 132 of the mesh fabric cover 130 is provided with an extension protruding portion 132a protruding in the radial direction outside the vertical extension portion 131, and the outer wall 111 of the main body 110 is provided with an extension groove portion 111b recessed in the radial direction to correspond to the extension protruding portion, such that when the vertical extension portion 131 is inserted in the gap A between the inner wall 113 and the outer wall 111, the extension protruding portion 132a is correspondingly engaged with the extension groove portion 111b. Thereby, a more rigid coupling of the mesh fabric cover 130 to the main body 110 can be achieved.

(29) Meanwhile, considering cosmetics with a lower viscosity, as shown in FIGS. 7 and 8, under the mesh fabric cover 130, in addition to the sponge 140 and the auxiliary mesh fabric cover 150, a second sponge 160 and a second auxiliary mesh fabric cover 170 may be further provided. In the embodiment, the individual structures of the second sponge 160 and the second auxiliary mesh fabric cover 170 are the same as those of the sponge 140 and the auxiliary mesh fabric cover 150 described above.

(30) Accordingly, even if the cosmetic accommodated in the accommodation space S has a considerably low viscosity, it is possible to solve the leakage problem of low viscosity cosmetics when the sponge 140, the auxiliary mesh fabric cover 150, the second sponge 160, and the second auxiliary mesh fabric cover 170 are further provided based on the mesh fabric cover 130.

(31) Here, the edge of the second sponge 160 and an outer edge of the second auxiliary rim portion 171 of the second auxiliary mesh fabric cover 170 are locked by being pressed along with the edge of the sponge 150 and the outer edge of the auxiliary rim portion 151 of the auxiliary mesh fabric cover 150 by the upper end of the inner wall 113 of the main body and the lower surface of the rim portion 132, by the vertical extension portion 131 inserted in the gap between the inner wall 113 and the outer wall 111.

(32) Also in this case, referring to FIG. 7, both the sponge 140 and the auxiliary mesh fabric 152 cover the accommodation space S while being spaced apart from each other by a predetermined vertical gap C by the auxiliary rim portion 151, and both the second sponge 160 and the second auxiliary mesh fabric 172 cover the accommodation space S while being spaced apart from each other by a predetermined vertical gap D due to the vertical thickness of the second auxiliary rim portion 171. Further, in spaces defined by the gaps C and D, the cosmetic in the accommodation space S seeps and is contained, and when the mesh fabric 133 is pressed by a user with the puff (reference numeral 13 in FIG. 1), the cosmetic contained in the gaps C and D serves as priming and thus is easily discharged outside. Accordingly, even in a multilayer structure constituted by the mesh fabric 133, the sponge 140, the auxiliary mesh fabric 152, the second sponge 160, and the second auxiliary mesh fabric 172, it is possible to use cosmetics without inconvenience.

(33) Further, also in FIG. 8, the vertical extension portion 131 of the mesh fabric cover 130 is provided on an inner surface thereof with protruding portions 131a and 131b vertically spaced apart from each other, and as shown in FIG. 7, the inner wall 113 of the main body 110 is provided with groove portions 113a and 113b vertically spaced apart from each other in the radial direction to correspond to the protruding portions.

(34) Accordingly, when the vertical extension portion 131 is engaged with the gap A between the inner wall 113 and the outer wall 111 of the main body 110, the protruding portions 131a and 131b are engaged with the groove portions 113a and 113b respectively, whereby it is possible to improve the coupling strength of the mesh fabric cover 130 to the main body 110.

(35) Here, of the two protruding portions 131a and 131b, the upper protruding portion 131a supports the outer edge of the second auxiliary rim portion 171 of the second auxiliary mesh fabric cover 170 when the sponge 140, the auxiliary mesh fabric cover 150, the second sponge 160, and the second auxiliary mesh fabric cover 170 are inserted under the mesh fabric cover 130 as shown in FIG. 7, such that the sponge 140, the auxiliary mesh fabric cover 150, the second sponge 160, and the second auxiliary mesh fabric cover 170 accommodated in the vertical extension portion 131 are prevented from being separated from the vertical extension portion.

(36) Meanwhile, in FIG. 6, when the auxiliary mesh fabric cover 150 turned upside down is coupled to the sponge 140 and the mesh fabric cover 130 and then is coupled to the main body 110, a coupling structure is shown as shown in FIG. 9. Herein, depending on the thickness and type of a sponge 140, there may be provided a structure in a convex shape brought in contact with and supported by both the upper mesh fabric 133 and the lower auxiliary mesh fabric 152. Of course, in a similar manner, in the state of FIG. 9, under the auxiliary mesh fabric cover 150, the second sponge 160 and the second auxiliary mesh fabric cover 170 may be further provided to implement a five-layer structure of FIG. 10.

(37) 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.
