The present application claims priority to Korean Patent Application No. 10-2021-0130637, filed on Oct. 1, 2021, the entire contents of which is incorporated herein for all purposes by this reference.
The present invention relates to a residual quantity prevention stick container having a sealed structure, and more particularly, to a residual quantity prevention stick container having a sealed structure to prevent contamination and deterioration of a stick cosmetic accommodated therein through a systematic coupling relationship and a stable sealing structure between adjacent components.
In today's modern society, both men and women of all ages use cosmetics upon needs in accordance with the rapid diversification trend of the times. In particular, women use cosmetic products and cosmetic tools with various types and various colors, and various high-quality cosmetic products and tools are being released into the market everyday through the research and development of cosmetics-related companies.
According to the purpose of use, the cosmetics are classified into, for example, facial cleansing cosmetics used for removing sebum, wastes and contaminants on a surface of a skin, base cosmetics used for properly supplying moisture and oil to the skin, color cosmetics used for expressing beautiful colors, hair cosmetics used for protecting hairs and supplying nutrition as well as removing foreign substances from hairs or scalp, and perfumes obtained by dissolving fragrant materials in alcohol or the like and used for giving a fragrance to others.
The color cosmetics are divided into a base makeup used for uniformizing the skin color and cover the defects, and a point makeup for partially enhancing the three-dimensional feeling such as lips, eyes, nails. The base makeup includes a makeup base, a foundation, a powder, and so on, and the point makeup includes a lipstick, an eye liner, and a mascara.
In addition, the foundation refers to cosmetics used to naturally hide blemishes or melasma on the skin, such as the face, exposed to the outside, or express the clean and bright skin or clear and soft skin. When used for makeup, the foundation is spread evenly on the skin without clumping by using a cosmetic puff.
The foundation is usually stored in a wide and flat compact container, and the puff is accommodated inside the compact container together.
However, in order to use the foundation accommodated in the compact container, a user is required to open a lid of the container, hold the puff accommodated on an upper lid of an inner container, open the lid of the inner container, and then apply the foundation cosmetics to the skin by using the puff. Thus, it is inconvenient to use, and a hand of the user gets dirty because the foundation cosmetics remaining on the puff are put thereon in the above process.
Accordingly, for the convenience in use and the convenience in portable storage, a stick-type cosmetic container has been developed in which a stick-type cosmetic is mounted on one side of a container, and the stick-type cosmetic mounted inside the container is used by raising and lowering the stick-type cosmetic according to rotation of the container.
For the conventional stick-type cosmetic container having the above structure, Korean Unexamined Patent No. 10-2017-0049149 (hereinafter referred to as ‘related art’) discloses a lipstick container in which a lipstick is drawn out or drawn in by screw rotation, and the related art will be described as follows.
the above related art includes: a lipstick case; a guide tube coupled to an upper inner side of the lipstick case and formed with a guide protrusion on an inner circumference; a rotating body coupled to a lower inner side of the lipstick case and the guide tube, and formed with a rotating body thread on an upper inner circumference; a lipstick plate coupled to an upper inner side of the guide tube, formed on a lower outer circumference thereof with a plate thread screwed with the rotating body thread, and formed on one side of the plate thread with a vertical guide groove into which the guide protrusion is inserted; a lipstick mounted on the lipstick plate; and a lipstick cover detachably coupled to the upper part of the lipstick case.
However, the conventional lipstick container wastes resources since all of the lipstick cosmetics remaining in the lipstick plate cannot be used. In addition, it is inconvenient to use a separate tool to constrainedly dig and use the stick-type cosmetics remaining in the lipstick plate.
In order to solve the above-described problems, Korean Unexamined Patent No. 10-2021-0097018 (hereinafter referred to as ‘related art’) discloses a stick-type cosmetic container. The above related art includes: a body; a rotating body rotatably coupled to a main body and having a rotating thread; an elevating member coupled to an inside of the main body to elevate, provided with a stick cosmetic, and formed thereon with an elevating thread; a residue withdrawal member coupled to the elevating member to push out the stick cosmetic and formed thereon with a screw protrusion; an elastic member formed between the elevating member and the residue withdrawal member; and a cover detachably coupled to the rotating body. Accordingly, when the stick-type cosmetic container is used, the stick-type cosmetics accommodated therein are entirely used without any residue.
However, since the above related art has no airtight structure between the main body and the rotating body rotated with respect to the main body and at an inlet of the main body, external air is introduced through gaps. Accordingly, when carried or stored, the stick cosmetics stored in the rotating body are hardened or contaminated and deteriorated. In addition, according to the above related art, since the elevating member to which the stick cosmetic is attached and the residue withdrawal member for pushing the stick cosmetics remaining in the elevating member to the outside are separately screwed with the main body and operated, the productivity may be decreased due to the complicated assembling, and the smooth withdrawal operation of the stick cosmetic may be hindered.
In order to solve the above problems, the present invention provides a stick container having a sealing structure for preventing a residue in which a sealing tube is formed between a main body and a guide tube to simultaneously seal spaces between the main body and the sealing tube and between the sealing tube and the guide tube, and a sealing cap is formed on an inside of a main body cover to seal an inlet of the guide tube, so that the stick cosmetic accommodated in the guide tube may be prevented from being contaminated and deteriorated when being carried or stored.

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.
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.
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.
As shown in
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.
As shown in
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
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.
As shown in
As shown in
In addition, as shown in
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.
As shown in
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.
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.
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.
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.
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.
As shown in
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.
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.
As shown in
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.
In addition, as shown in
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.
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
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.
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.
Then, as shown in
Thereafter, the cosmetic stick S drawn to the outside from the guide tube 30 is evenly applied to the skin during makeup.
In addition, as shown in
Thereafter, as shown in
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.
