BEST MODE

(7) Hereinafter, an embodiment of a sealed lipstick case according to the present disclosure will be described in detail with reference to the accompanying drawings.

(8) As illustrated in FIGS. 2 to 6, the sealed lipstick case according to the present disclosure used by allowing a lipstick R to be moved up and down due to rotation of the lipstick R includes: a lipstick lift part 10 enabling the lipstick R to be moved up and down during the rotation of the lipstick R; a lower main body 20 having a coupling part 21 formed therein by extending upward from an inner lower surface of the lower main body 20 such that a lower inner circumferential surface of the lipstick lift part 10 is fitted over and coupled to the coupling part 21; and an upper cap 30 having a lower inner circumferential surface coupled to an upper outer circumferential surface Of the lower main body 20, wherein the upper cap 30 has a sealing part 35 provided therein, the sealing part 35 comprising: a fitting support end 31a forcibly fitted to an upper inner surface of the upper cap 30; an inner hook 31 having a pair of holding parts 31b extending downward from a lower surface of the fitting support end 31a; an inner cap 32 having a hook holding end 32a provided thereon such that the holding parts 31b are coupled to an inner circumferential surface of the hook holding end 32a by being inserted thereto; and a spring S sitting on an outer circumferential surface of the hook holding end 32a such that the inner hook 31 and the inner cap 32 are spaced apart from each other by facing each other.

(9) Here, the upper end of the spring S is supported by the lower surface of the fitting support end 31a, and the lower end of the spring S is supported by the upper surface of the inner cap 32 located under the hook holding end 32a, whereby the inner hook 31 and the inner cap 32 push each other to face each other by using the elastic force. That is, during the coupling of the lower main body 20 to the upper cap 30, the elastic force of the spring S brings the lower part of the inner cap 32 into close contact with the upper part of the lower main body 20. Additionally, during the decoupling of the lower main body 20 from the upper cap 30, the removal of the inner cap 32 to the outside is prevented by the operation of the holding part 31b and the hook holding end 32a.

(10) In addition, a holding jaw 31b′ is formed at a lower end part of each of the holding parts 31b by protruding outward therefrom, and a pair of insertion holes 32a′ are formed through the hook holding end 32a such that the holding jaw 31b′ is held in each of the insertion holes, so the holding jaw 31b′ prevents the inner cap 32 from being removed to a part located under the upper cap 30.

(11) Furthermore, a main body coupling part 22 is formed at an upper part of the lower main body 20 by being recessed inward therefrom such that the main body coupling part 22 is coupled to an inner circumferential surface of the upper cap 30, and a close contact end 32b is provided at a lower part of the inner cap 32 such that the close contact end 32b is coupled to an upper outer circumferential surface of the main body coupling part 22 by being in close contact therewith. Here, as illustrated in FIG. 3, the inner circumferential surface of the close contact end 32b is formed by being recessed toward the inside of the inner cap 32 more than the upper part of the inner cap 32.

(12) Multiple flexible fastening ends 32b′ are formed at a lower end part of the close contact end 32b by being spaced apart from each other by predetermined distances along a circumference thereof such that each of the flexible fastening ends 32b′ is easily flexible inward and outward when the lower end part of the close contact end 32b is coupled to the upper outer circumferential surface of the main body coupling part 22, and a curved support end 32b″ is formed on an upper inner circumferential surface of the close contact end 32b by being recessed therefrom to be curved inward such that the curved support end 32b″ is in close contact with an upper end of the main body coupling part 22.

(13) A repressed fastening end groove 22a is formed in an outer circumferential surface of the main body coupling part 22 by being repressed inward therefrom such that an inner surface of the flexible fastening end 32b′ sits in the repressed fastening end groove 22a; a ring-shaped coupling jaw 22b is formed at a part located under the repressed fastening end groove 22a by protruding outward therefrom such that the coupling jaw 22b is coupled to the lower inner circumferential surface of the upper cap 30; and a ring-shaped lower cap-coupling jaw 30a is formed on the lower inner circumferential surface of the upper cap 30 by protruding therefrom such that the lower cap-coupling jaw 30a is held by a lower end part of the coupling jaw 22b when the lower cap-coupling jaw 30a sits on the main body coupling part 22 by being fastened thereto, so the coupling of the main body coupling part 22 and the upper cap 30 is improved.

(14) Meanwhile, the flexible fastening end 32b′ and the curved support end 32b″ of the close contact end 32b sit in and are in close contact with the repressed fastening end groove 22a and the upper end of the main body coupling part 22, respectively.

(15) Additionally, the coupling jaw 22b and the lower cap-coupling jaw 30a include a pair of coupling jaws 22b and a pair of lower cap-coupling jaws 30a, respectively, provided by being spaced apart from each other by a predetermined distance such that a fastening force of the coupling jaw 22b to the lower cap-coupling jaw 30a is increased, so the fastening force of the coupling jaw 22b to the lower cap-coupling jaw 30a is improved compared to when a coupling jaw 22b and a lower cap-coupling jaw 30a are provided.

(16) A support end holding jaw 30b is provided on the upper inner circumferential surface of the upper cap 30 by protruding inward therefrom such that the lower end part of the fitting support end 31a is supported by the support end holding jaw 30b when the fitting support end 31a is forcibly fitted to the upper inner circumferential surface of the upper cap 30, so the inner hook 31 is securely coupled to and held by the upper inner circumferential surface of the upper cap 30.

(17) Meanwhile, the lipstick lift part 10 according to the embodiment of the present disclosure includes: a lipstick holder 11 having the lipstick R filled on the upper inner circumferential surface of the lipstick holder 11 and a pair of raising/lowering protrusions 11a formed on the outer circumferential surface of the lipstick holder 11 by protruding outward therefrom to face each other; a rotation guide tube 12 having threads N formed in an inner circumferential surface thereof to guide the raising/lowering of the lipstick holder 11, the threads N allowing the raising/lowering protrusions 11a to sit therein; a holder guide tube 13 having a pair of guide paths 13a formed vertically therethrough such that the upper outer circumferential surface of the holder guide tube 13 is fitted to the inner circumferential surface of the rotation guide tube 12 and the raising/lowering protrusions 11a of the lipstick holder 11 sit in the threads N of the rotation guide tube 12 by passing through the holder guide tube 13; and a guide protection tube 14 covering the upper end part of the holder guide tube 13 and being in close contact with the outer circumferential surface of the rotation guide tube 12.

(18) Various embodiments of the lipstick lift part 10 are disclosed in a conventional technology.

(19) The lipstick lift part 10 is not limited to the embodiment described above, but may be variously embodied. lipstick holder 11 is moved up and down during the rotation of the lower main body 20.

(20) In addition, the holder guide tube 13 is provided to be integrated with the coupling part 21 formed inside the lower main body 20 such that the lower part of the holder guide tube 13 is coupled to the coupling part 21, and with the guide protection tube 14 and the rotation guide tube 12 fixed, the lipstick holder 11 is moved up and down during the rotation of the lower main body 20.

(21) The operation of the sealed lipstick case having the above configuration according to the present disclosure will be described below.

(22) As illustrated in FIGS. 2 to 6, in the sealed lipstick case according to the present disclosure, the inner cap 32 moved to face the inner hook 31 is provided such that the lower end of the sealing part 35 provided inside the upper cap 30 is in close contact with the upper end of the lower main body 20, and the inner cap 32 is moved by the elastic force of the spring S.

(23) Here, in the inner hook 31, the fitting support end 31a is coupled to and held in the upper part of the support end holding jaw 30b formed on the upper inner circumferential surface of the upper cap 30 by forcible fitting.

(24) Meanwhile, the spring S is supported by the lower surface of the fitting support end 31a and the elastic force of the spring S is applied to the surface of the inner cap 32 located under the hook holding end 32a, so the inner cap 32 is moved to the upper part of the lower main body 20. Additionally, to prevent the removal of the inner cap 32 due to the elastic force of the spring S applied to the inner cap 32, the holding jaw 31b′ formed on the holding part 31b of the inner hook 31 is held in the insertion hole 32a′ of the hook holding end 32a, so in spite of the application of the elastic force of the spring S, the inner cap 32 is prevented from being removed to the outside.

(25) Furthermore, the multiple flexible fastening ends 32b′ are formed at the lower end part of the close contact end 32b provided at the lower part of the inner cap 32 by cutting the lower end part of the close contact end 32b such that the multiple flexible fastening ends 32b′ are spaced apart from each other by predetermined distances, so the multiple flexible fastening ends 32b′ are easily coupled to the main body coupling part 22 of the lower main body 20. That is, the flexibility of the flexible fastening ends 32b′ allows the close contact end 32b of the inner cap 32 to be easily fitted over and coupled to the outer circumferential surface of the main body coupling part 22.

(26) Accordingly, as for the close contact end 32, when the flexible fastening end 32b′ sits in the repressed fastening end groove 22a of the main body coupling part 22, the curved support end 32b″ of the upper inner surface of the close contact end 32b is in close contact with the upper end of the main body coupling part 22, so sealing force of the sealed lipstick case is improved.

(27) In addition, the pair of coupling jaws 22b is formed on the outer circumferential surface of the main body coupling part 22, and the upper part of the lower cap-coupling jaw 30a of the lower inner circumferential surface of the upper cap 30 is in contact with the lower part of each of the coupling jaws 22b so as to seal the sealed lipstick case. The lower cap-coupling jaw 30a and the coupling jaw 22b include a pair of lower cap-coupling jaws 30a and a pair of coupling jaws 22b, respectively, whereby the sealing force between the lower main body 20 and the upper cap 30 is improved, and the elastic force of the spring S acts to lift the upper cap 30, so the sealing force between the lower cap-coupling jaw 30a and the coupling jaw 22b is further improved.

(28) Accordingly, in the sealed lipstick case of the present disclosure, due to the sealing-type coupling of the upper cap 30 by which the lower main body 20 receiving the lipstick R and the sealing part 35 are coupled to the inside of the upper cap 30, the lipstick R is tightly sealed from outside air and can be prevented from being contaminated, deteriorated, and solidified.

(29) The present disclosure is not limited to the specific exemplary embodiment described above, and anyone with ordinary knowledge in a technical field to which the present disclosure pertains can implement various modifications without departing from the gist of the present disclosure claimed in the claims. Such modifications fall within the scope of the description of the claims.
