[0048] As shown in the drawings, the stick container having a sealing structure for preventing a residue according to the embodiment of the present invention may include a main body 10, a sealing tube 20, a guide tube 30, a first holder 40, a second holder 50, and a main body cover 60.

[0049] Each component of the stick container having a sealing structure for preventing a residue according to the embodiment of the present invention will be described as follows.

[0050] The main body 10 has a cylindrical shape with one side open, so that a stick cosmetic S is ejected to the outside or inserted to the inside of the guide tube 30. In the drawing of the stick container according to one embodiment of the present invention, the main body 10 is shown as having a rigid cylindrical shape elongated along the ejected or inserted direction of the stick cosmetic S. However, the present invention is not limited thereto, and may also be formed in various shapes and formed of various materials.

[0051] As shown in FIG. 2, a rotating operation tube 12 is spaced apart from an outer wall inside the main body 10 at a predetermined interval. The rotating operation tube 12 has a shape of a tube (that collectively refers to an object having a body with a round circumference and a hollow inside) extending in a longitudinal direction of the main body 10, in which at least a portion of the second holder 50 may be inserted therein, and an elevation protrusion 12a may protrude from an inner circumference thereon so as to be screw-fastened to an elevation thread 52 of the second holder 50. The elevation protrusion 12a may be formed in a protrusion shape extending by a predetermined section along the inner circumference of the rotating operation tube 12, or may be formed in a thread shape screw-fastened to the elevation thread 52.

[0052] In addition, a filling hole 14 for filling the stick cosmetic S therethrough may be formed on one side of the main body 10, that is, on the other side of the open portion, and a lower cap 70 may be further provided to be coupled to the filling hole 14. The filling hole 14 is provided to fill the main body 10 with the stick cosmetic S in a lower filling manner.

[0053] As shown in FIG. 3, the lower cap 70 may be formed thereon with an inner extension protrusion wheel 72 vertically extending from one surface of a bottom plate and an outer extension protrusion wheel 74 outwardly spaced apart from the inner extension protrusion wheel 72 at a predetermined interval. An inner sealing protrusion 72a and an outer sealing protrusion 74a may be formed on outer circumferences of the inner extension protrusion wheel 72 and the outer extension protrusion wheel 77, respectively, so as to dually seal the inside of the main body 10 while coming into tight contact with a lower inner wall of the main body 10.

[0054] The sealing tube 20 is inserted into the open portion of the main body 10 so as to be fixedly coupled to the inside of the main body 10. As shown in FIG. 2, the sealing tube 20 is formed in a cylindrical shape with open upper and lower portion, and disposed between the main body 10 and the guide tube 30 to simultaneously seal spaces between the main body 10 and the sealing tube 20 and between the sealing tube 20 and the guide tube 30.

[0055] A seating protrusion wheel 22 seated on an upper end of the main body 10 protrudes on an outer circumference of the sealing tube 20, in which a sealing part 24 inserted into the main body 10 to seal the space between the body 10 and the guide tube 30 may be formed at one side of the seating protrusion wheel 22, and a detachable part 26 exposed to the outside of the main body 10 and detachably coupled to the main body cover 60 may be formed at the other side of the seating protrusion wheel 22.

[0056] As shown in FIG. 4, a first sealing part 24a may be formed at an end of the sealing part 24 of the sealing tube 20. The first sealing part 24a may be formed to be opened outward toward the end of the sealing part 24 to come into close contact with the inner circumference of the main body 10, thereby stably maintaining airtightness inside the main body 10 while blocking the gap between the main body 10 and the sealing tube 20. The main body 10 may have an inner diameter at a portion in contact with the sealing part 24 so as to be smaller than other portions. This is configured such that the sealing part 24 is easily inserted into the main body 10 and the first sealing part 24a simultaneously comes into strongly close contact with a portion of the inner circumference of the main body 10.

[0057] As shown in FIG. 5, a second sealing part 24b may be formed on the inner circumference of the sealing part 24 of the sealing tube 20. The second sealing part 24b may protrude along the inner circumference of the sealing part 24 to come into close contact while surrounding the outer circumference of the guide tube 30, thereby stably maintaining the airtightness inside the guide tube 30 while blocking the gap between the guide tube 30 and the sealing tube 20. An elastic groove 24c may be formed on an opposite side of the second sealing part 24b so that the sealing part 24 may have a partially thinned thickness. This is configured such that the second sealing part 24b is outwardly opened more elastically upon coming into contact with the outer circumference of the guide tube 30.

[0058] In addition, as shown in FIG. 3, a first locking protrusion 24d may protrude from the inner circumference of the sealing part 24 of the sealing tube 20.

[0059] The guide tube 30 may be rotatably coupled to the inner space of the main body 10, so as to guide linear movements of the first holder 40 and the second holder 50 formed therein.

[0060] As shown in FIG. 2, an inlet part 32 through which the stick cosmetic S is drawn out or drawn in may be formed on one side of the guide tube 30, in which at least a portion thereof may be inserted into the sealing tube 20 and rotatably fastened to the sealing tube 20, and the remaining portion may be exposed to the outside of the main body 10.

[0061] A partition plate 34 may be formed inside the guide tube 30, in which the partition plate 34 may divide the inner space of the guide tube 30 into a space in which the cosmetic stick S is moved and a space in which the first and second holders 40 and 50 are lifted and lowered. the partition plate 34 may be formed therein with a first through-hole 34a through which the first holder 40 passes to guide the linear movement of the first holder 40, and a second-through hole 34b, through which the second holder 50 passes to guide the linear movement of the second holder 50, may be formed at an inner side of the first through-hole 34a. It may be preferable that the second through-hole 34b is formed in an oval shape or a circular shape in which at least a portion is a straight side such that the guide tube 30 and the second holder 50 are rotatable together.

[0062] In addition, a second locking protrusion 36 may protrude from the outer circumference of the guide tube 30 so as to be locked and coupled to the first locking protrusion 24d of the sealing tube 20, so that the guide tube 30 may be prevented from being separated from the main body 10.

[0063] The first holder 40 is movably coupled into the guide tube 30 in a straight line along the longitudinal direction of the guide tube 30.

[0064] The first holder 40 is mounted therein with the stick cosmetic S to draw out or draw in the stick cosmetic S while moving the stick cosmetic S along the guide tube 30, and may include an accommodation part 42 for accommodating the cosmetic stick S and a lower extension part 44 extending downward from the accommodation part 42.

[0065] The accommodation part 42 may be formed in a bottom portion thereof with a holder through-hole 42a through which the second holder 50 passes, and have an inner circumference and a bottom surface from which at least one contact plate 42b extends toward a center thereof, thereby increasing the adhesion between the accommodation part 42 and the stick cosmetic S. In other words, a plurality of contact plates 42b having relatively wide both sides penetrate into the stick cosmetic S to increase the contact area between the contact plate 42b and the cosmetic stick S, thereby preventing the cosmetic stick S from being easily separated from the accommodation part 42. The height of an outer wall of the accommodation part 42 or the number, size or shape of the contact plate 42b may be variously changed for the adhesion between the stick cosmetic S and the accommodation part 42 and the stable fixation of the stick cosmetic S.

[0066] As shown in FIG. 3, the lower extension part 44 is coupled to the inside of the guide tube 30 while passing through the first through-hole 34a of the guide tube 30, in which a first separation prevention protrusion 44a may protrude from the outer circumference of the lower extension part 44 to limit the linear movement section of the first holder 40. In other words, when the first holder 40 ascends for a predetermined section and the first separation prevention protrusion 44a is caught on the partition plate 34 of the guide tube 30, the ascending of the first holder 40 is stopped and only the second holder 50 coupled to the inside of the first holder 40 ascends, so that the second holder 50 pushes the stick cosmetic S remaining in the accommodation part 42 of the first holder 40 to the outside, and accordingly, the residue of the stick cosmetic S may be entirely used. It may be preferable that at least one pair of the lower extension part 44 of the first holder 40 is formed on one side of the accommodation part 42 for the stable linear movement of the first holder 40.

[0067] The second holder 50 is movably coupled to the inside of the first holder 40 in a straight line along the longitudinal direction of the first holder 40.

[0068] The second holder 50 is screw-coupled to the main body 10, moved in a straight line by the rotation of the main body 10 and lifted and lowered alone or together with the first holder 40, and may include a holder plate 52 disposed inside the first holder 40 to push out the stick cosmetic S accommodated in the first holder 40, and an elevation part 54 extending from one side of the holder plate 52.

[0069] As shown in FIG. 2, at least one slit 52a is formed in an edge portion of the holder plate 52, in which the contact plate 42b of the first holder 40 is inserted into the slit 52a, and accordingly, the second holder 50 is stably linearly moved without being idle from the first holder 40.

[0070] The elevation part 54 is coupled to the inside of the guide tube 30 while passing through the second through-hole 34b of the guide tube 30, in which an elevation thread 54a is formed on an outer circumference of the elevation part 54 so as to be screw-coupled to the elevation protrusion 12a of the main body 10, and lifted and lowered by rotating the main body 10. In addition, a second separation prevention protrusion 54b may protrude from the lower outer circumference of the elevation part 54 to limit the linear movement section of the second holder 50. In other words, when the second holder 50 solely ascends inside the first holder 40 and the second separation prevention protrusion 54a is caught on the partition plate 34 of the guide tube 30, the ascending of the second holder 50 is stopped.

[0071] In addition, as shown in FIG. 3, a first locking protrusion wheel 42c may protrude from the inner circumference of the accommodation part 42 of the first holder 40, and a second locking protrusion wheel 54c may protrude from the outer circumference of the elevation part 54 of the second holder 50, so as to be locked and coupled to each other, so that the first holder 40 and the second holder 50 may be lifted and lowered together in a predetermined section. In other words, the first holder 40 is moved upward together with the second holder 50 by rotation of the main body 10 in a state in which the first locking protrusion wheel 42c of the first holder 40 and the second locking protrusion wheel 54c of the second holder 50 are locked and coupled to each other. Immediately when the first separation prevention protrusion 44a of the first holder 40 is caught on the partition plate 34 of the guide tube 30, the second locking protrusion wheel 54c of the second holder 50 passes over the first locking protrusion wheel 42c of the first holder 40, and thus only the second holder 50 is moved upward.

[0072] The main body cover 60 opens or closes at least a portion of the guide tube 30 while being fastened to the detachable part 26 of the sealing tube 20. In the drawings of the stick container according to the embodiment of the present invention, the main body 10 and the main body cover 60 are shown as being fastened by the protrusion and the groove. However, the present invention is not limited thereto, and may have various types of fastening structures, such as undercut coupling, forced fitting coupling, and magnetic coupling, within a range for allowing the body cover 60 to be easily detachably fastened to the main body 10.

[0073] In addition, a sealing cap 80 may be provided inside the main body cover 60 to seal the inlet part 32 of the guide tube 30. As shown in FIG. 6, the sealing cap 80 stably seals the inlet part 32 of the guide tube 30 while outwardly enclosing the end of the guide tube 30. An oblique surface 82 may be formed on an inner circumference of the sealing cap 80 to come into close contact with an upper edge of the guide tube, and the lower inner circumference of the sealing cap 80 may simultaneously come into close contact with the upper outer circumference of the guide tube 30.

[0074] As described above, the present invention relates to a stick container in which the first holder 40 and the second holder 50 are sequentially lifted and lowered by the rotation operation of the main body 10, so as to entirely use the stick cosmetic S attached to the first and second holders 40 and 50 without wasting, in which the sealing tube 20 is provided between the main body 10 and the guide tube 30 to simultaneously seal the gaps between the main body 10 and the sealing tube 20 and between the sealing tube 20 and the guide tube 30, and the sealing cap 80 is provided on the inside of the body cover 60 to seal the inlet part 32 of the guide tube 30, so that the stick cosmetic S accommodated in the guide tube 32 can be prevented from being contaminated and deteriorated when being carried or stored. In other words, the stick cosmetic S is accommodated inside the guide tube 30, and portions of the guide tube 30 with the possibility of inflow of external air are effectively sealed through the sealing tube 20 and the sealing cap 80, so that the airtightness inside the guide tube 30 can be more stably maintained.

[0075] FIGS. 7 to 9 are views illustrating the operation processes of the stick container having a sealing structure for preventing a residue according to the embodiment of the present invention. The use process of the stick container having a sealing structure for preventing a residue according to the embodiment of the present invention will be described with reference to the above drawings.

[0076] FIG. 7 is a sectional view illustrating a state in which the first holder and the second holder are lifted together according to the embodiments of the present invention. FIG. 8 is a sectional view illustrating a state in which the lifting of the first holder is restricted according to the embodiments of the present invention. FIG. 9 is a sectional view illustrating a state in which the second holder is lifted according to the embodiments of the present invention.

[0077] In order to use the stick container having a sealing structure for preventing a residue according to the embodiments of the present invention, first, the main body cover 60 is separated from the main body 10 to expose the guide tube 30 to the outside.

[0078] Then, as shown in FIG. 7, when the guide tube 30 is held by one hand and the main body 10 is rotated by the other hand, the sealing tube 20 fitted inside the main body 10 is rotated together with the main body 10. The main body 10 and the sealing tube 20 are rotated, however, the guide tube 30 held by the user and the first and second holders 40 and 50 coupled to the inside of the guide tube 30 are restricted in rotation, and accordingly, the second holder 50 screw-coupled to the main body 10 and the first holder 40 locked and coupled to the second holder 50 are moved upward together along the guide tube 30, so that the cosmetic stick S attached to the first holder 40 is drawn outward through the inlet part 32 of the guide tube 30.

[0079] Thereafter, the cosmetic stick S drawn to the outside from the guide tube 30 is evenly applied to the skin during makeup.

[0080] In addition, as shown in FIG. 8, in order to use the residue of the stick cosmetic S remaining inside the first holder 40 when the stick cosmetic S attached to the first holder 40 is almost used, the main body 10 is rotated so that the second holder 50 screw-coupled to the main body 10 and the first holder 40 locked and coupled to the second holder 50 are moved upward together along the guide tube 30, and then the first separation prevention protrusion 44a of the first holder 40 is caught on the partition plate 34 of the guide tube 30, thereby stopping the ascending of the first holder 40.

[0081] Thereafter, as shown in FIG. 9, when the main body 10 is continuously rotated, the second locking protrusion wheel 54c of the second holder 50 passes over the first locking protrusion wheel 42c of the first holder 40, and only the second holder 50 is moved upward, so that the holder plate 52 of the second holder 50 pushes the cosmetic stick S remaining inside the accommodation part 42 of the first holder 40 to the outside.

[0082] After the makeup is completed, the main body 10 is rotated in the opposite direction to insert the cosmetic stick S into the guide tube 30, and then the main body cover 60 covers the guide tube 30 and is coupled to the sealing tube 20 again so as to be stored or carried. The first sealing part 24a of the sealing tube 20 comes into close contact with the inner circumference of the main body 10 to seal the space between the main body 10 and the sealing tube 20, and the second sealing part 24b simultaneously comes into close contact with the outer circumference of the guide tube 30 to seal the space between the sealing tube 20 and the guide tube 30, and the sealing cap 80 of the main body cover 60 covers and comes into close contact with the inlet part 32 of the guide tube 30, thereby sealing the inside of the guide tube.

[0083] Although the invention has been described with the particulars such as specific elements, the limited embodiments, and the drawings, the above description is provided only to help comprehensive understanding of the present invention, and the present invention is not limited to the above embodiments. It is obvious to those skilled in the art that various changes and modifications may are available. Therefore, the spirit of the present invention should not be limited to the aforementioned embodiments, and the following claims as well as all modifications or variations belonging to the equivalents of the claims will be within the scope of the invention.
