Description

Stick-type cosmetic container

[0001] The present invention relates to a stick-type cosmetic container, and more specifically, to a stick-type cosmetic container in which the stick-type cosmetic is raised and lowered to a certain length by rotational operation.

[0002] Generally, women use various cosmetics to enhance their appearance, and among the aforementioned cosmetics, color cosmetics are used for the purpose of making the skin beautiful by changing the appearance beautifully.

[0003] The above-mentioned color cosmetics are used to even out skin tone and cover imperfections, and are classified into base makeup and point makeup, which enhances the three-dimensional effect on specific areas such as lips, eyes, and nails. The above-mentioned base makeup consists of makeup base, foundation, powder, etc., and the point makeup consists of lipstick, eyeliner, mascara, etc.

[0004] The above foundation is a cosmetic product used to naturally conceal blemishes or freckles on skin exposed to the outside, such as the face, or to express clean, radiant skin or clear, matte skin. When applying makeup using the above foundation, it is spread evenly on the skin without clumping using a makeup puff.

[0005] These foundations are generally stored in a wide and flat compact container, and a puff is built inside the compact container.

[0006] However, in order to use the foundation contained in the compact container, the user had to open the container lid, hold the puff contained in the upper part of the container lid, open the container lid, and then pick up the foundation cosmetic with the puff and apply it to the skin, which was inconvenient to use, and in this process, there was a problem where the foundation cosmetic remaining on the puff got on the user's hands and became messy.

[0007] Accordingly, a stick-type cosmetic container has been developed to provide convenience of use and portability, wherein a stick-type cosmetic is mounted on one side of the container and the stick-type cosmetic mounted inside the container is raised and lowered according to the rotation of the container.

[0008] A conventional stick-type cosmetic container having such a structure is disclosed in Korean Registered Utility Model No. 20-0393382. The aforementioned prior art comprises a housing, a lower cap coupled to the lower part of the housing and having a screw-shaped lifting guide hole formed therein, an operating member that moves up and down according to the rotation of the lower cap, a storage member that moves up and down together with the operating member and has a stick-shaped cosmetic attached thereto, a protective tube that supports the up and down of the storage member and stores the stick-shaped cosmetic, and an upper cap that seals the protective tube. The structure is such that when the housing is rotated while the protective tube is held, the stick-shaped cosmetic is inserted or removed from the protective tube.

[0009] However, the aforementioned conventional technology had the inconvenience that the lifting and lowering length of the stick cosmetic resulting from the rotation of the housing was irregular each time, and that the housing had to be rotated finely to extend and retract the stick cosmetic to a consistent length. In addition, there was a problem of reduced convenience of use, as the stick cosmetic would extend from or be inserted into the protective tube due to the housing rotating as a result of user carelessness while applying makeup.

[0010] To solve the above-mentioned problems, a cosmetic tool was disclosed in Korean Registered Patent No. 10-1594253. The prior art described above has a structure in which a protrusion inlet is formed on a snap ring of a main body and a snap protrusion is formed on the outer circumference of a rotating part, so that the snap protrusion of the rotating part is forcibly passed through the inner surface of the snap ring and inserted into the protrusion inlet of the snap ring, thereby restricting the rotation of the rotating part.

[0011] However, the aforementioned conventional technology had a problem in that the rotating part had to be rotated strongly to force the snap projection of the rotating part to pass the inner surface of the snap ring, and as a result, women with relatively weak strength could not easily rotate the rotating part, making it inconvenient to use.

[0012] In addition, the aforementioned prior art had a problem in that, upon prolonged use, the snap protrusion of the rotating part would wear out due to friction with the inner surface of the snap ring, and as a result, the rotation limiting function of the rotating part through the snap ring could not be performed.

[0016] (Patent Document 002) Republic of Korea Registered Patent No. 10-1594253 (Published Feb. 17, 2016)

[0017] To solve the above-mentioned problems, the present invention aims to provide a stick-type cosmetic container that forms a lifting and lowering operation structure for a stick-type cosmetic by rotating a main body or a protective tube, and elastically controls the rotation between the main body and the protective tube at regular angles so that the rotation angle between the main body and the protective tube is constantly adjusted, thereby ensuring that the lifting and lowering length of the stick-type cosmetic is always maintained uniformly.

[0018] To achieve the above objectives, the present invention provides a stick-type cosmetic container comprising: a main body; a protective tube rotatably coupled to the main body, having an inlet portion and a first curved portion formed thereon; an operating member fixedly coupled to the main body and having an elastic portion formed on one side; a rotation angle adjusting member reciprocally coupled to the main body, elastically supported by the elastic portion, and having a second curved portion formed thereon; and a lifting member screw-coupled to the operating member and having a plate portion to which a stick-type cosmetic is attached, wherein a first guide portion having a first diagonal surface is formed on the elastic portion and a second guide portion having a second diagonal surface is formed on the rotation angle adjusting member, so as to interlock with each other to guide the reciprocating movement of the rotation angle adjusting member relative to the elastic portion.

[0019] In addition, the operating member may include a base plate seated on the bottom surface of the main body, an operating part extending from the center of the base plate and screw-coupled with a lifting member, and an elastic part extending from the bottom plate on the outside of the operating part and providing elasticity to a rotation angle adjustment member.

[0020] In addition, the first elastic part of the elastic part is formed to be inclined at a certain angle from the bottom of the operating member toward its center and contacts the outer circumference of the rotation angle adjustment member, and the second elastic part is formed to extend from the first elastic part to the inner wall of the main body so that its end contacts the inner wall.

[0021] In addition, the elastic part is composed of a first elastic part that acts elastically with respect to the bottom of the operating member and a second elastic part that acts elastically with respect to the inner wall of the main body, so that it can be elastically deformed or restored in a double manner.

[0022] Additionally, an auxiliary tension member is formed in the elastic member to assist in the elastic deformation of the second elastic member, wherein the auxiliary tension member may be formed by bending at least a portion of the second elastic member so as to face each other to form a groove between them, or by perforating at least a portion of the second elastic member to form a hole.

[0023] According to an embodiment of the present invention, the rotation angle between the main body and the protective tube is adjusted to a constant level, thereby maintaining the lifting length of the stick-type cosmetic at all times, which provides the effect of convenient use.

[0024] According to an embodiment of the present invention, as a rotation angle adjustment member formed inside the main body reciprocates elastically to control the rotation angle of the protective tube relative to the main body, the rotation angle between the main body and the protective tube can be easily adjusted with a small amount of force.

[0025] According to an embodiment of the present invention, as the elastic part formed inside the main body undergoes double elastic deformation to provide elasticity to the rotation angle adjustment member, the rotation angle adjustment function is smoothly performed even after prolonged use.

[0037] In the present invention, when a part is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0038] Hereinafter, a stick-type cosmetic container according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0039] FIG. 1 is a perspective view of a stick-type cosmetic container according to one embodiment of the present invention, FIG. 2 is an exploded perspective view from above of a stick-type cosmetic container according to one embodiment of the present invention, FIG. 3 is an exploded perspective view from below of a stick-type cosmetic container according to one embodiment of the present invention, and FIG. 4 is a cross-sectional view of a stick-type cosmetic container according to one embodiment of the present invention.

[0040] As described above, a stick-type cosmetic container according to one embodiment of the present invention comprises a main body (10), a protective tube (20), an operating member (30), a rotation angle adjustment member (40), and a lifting member (50), and by rotating the protective tube (20) relative to the main body (10), the operating member (30) and the lifting member (50) are screw-fastened to each other, thereby allowing the stick-type cosmetic to be drawn out to the outside or drawn in to the inside.

[0041]

[0042] A stick-type cosmetic container according to one embodiment of the present invention is described by dividing it according to each component as follows.

[0043]

[0044] The above-described main body (10) is a part that the user holds when applying makeup, and is formed in a three-dimensional shape having a certain space inside. In the drawing of a stick-type cosmetic container according to one embodiment of the present invention, the main body (10) is depicted as an ellipse consisting of a pair of planes parallel to each other and a curved surface connecting the ends of the pair of planes, but it is not limited thereto and may be formed in various shapes or materials considering usability or design elements.

[0045] As shown in FIG. 2, a through hole (12) is formed on one side of the main body (10). The through hole (12) is formed in the center of the surface in contact with the protective tube (20), and at least a portion of the protective tube (20) and the operating member (30) can pass through the through hole (12). The protective tube (20) is inserted from the outside into the inner space of the main body (10) and comes into contact with the rotation angle adjustment member (40), and the operating member (30) is inserted from the main body (10) into the inner space of the protective tube (20) and screw-coupled with the lifting member (50).

[0046] As shown in FIG. 3, a guide plate (14) is formed on the inner side of the main body (10). The guide plate (14) is formed extending downward from the inner upper surface of the main body (10), and a guide insertion groove (14a) may be formed in the guide plate (14). The guide insertion groove (14a) is configured to guide the reciprocating movement of the rotation angle adjustment member (40) relative to the main body (10). The guide insertion groove (14a) is formed extending in the longitudinal direction of the main body (10), and its end is open, and the rotation angle adjustment member (50) is inserted into the open part. At this time, it is preferable that the guide plate (14) be formed in at least one pair in the inner space of the main body (10) to assist in the stable reciprocating movement of the rotation angle adjustment member (40).

[0047] Additionally, the side opposite the through hole (12) of the main body (10) is open, and a finishing cap (16) can be attached to the open part. The finishing cap (16) blocks the open part of the main body (10) and becomes the bottom surface of the main body (10). It is formed in a shape corresponding to the open part of the main body (10), and an outer wall is extended to a certain height at the edge so that it is fitted into the open part of the main body (10) and fixed and attached.

[0048] Meanwhile, an overcap (60) may be detachably coupled to one side of the main body (10). The overcap (60) is coupled to or separated from the main body (10) to expose the protective tube (20) and the stick-type cosmetic contained therein to the outside or to protect it. In the drawing of the stick-type cosmetic container according to one embodiment of the present invention, the main body (10) and the overcap (60) are each shown having protrusions formed thereon to form an undercut connection with each other; however, this is not limited thereto, and various types of connection structures may be provided within the range where the overcap (60) can be easily attached to and detached from the main body (10), such as connection by protrusions and grooves, forced fitting connection, and screw connection.

[0049]

[0050] The protective tube (20) is rotatably coupled to the main body (10) and protects the lifting member (50) and the stick-type cosmetic attached to the lifting member (50) by wrapping around it. For design continuity, it is preferable that the protective tube (20) have the same diameter and surface shape as the end of the main body (10).

[0051] As shown in FIG. 4, the protective tube (20) has an opening (22) formed on one side, and a stick-type cosmetic can be drawn out to the outside or drawn into the protective tube (20) through the opening (22).

[0052] An insertion protrusion (24) may be extended and formed on the opposite side of the entrance portion (22) of the protective tube (20). The insertion protrusion (24) penetrates the through hole (12) of the main body (10), and at least a portion of it is inserted into the inner space of the rotation angle adjustment member (40). A protective tube catch projection (24a) is formed protruding from the outer circumference of the insertion protrusion (24). The protective tube catch projection (24a) is engaged with the outer wall of the through hole (12) of the main body (10) to prevent the protective tube (20) from detaching from the main body (10).

[0053] Meanwhile, a first curved portion (24b) for adjusting the rotation angle between the main body (10) and the protective tube (20) may be formed at the end of the insertion protrusion (24). The first curved portion (24b) is inserted into the inside of the rotation angle adjustment member (40) and comes into contact with the second curved portion (44) formed in the rotation angle adjustment member (40). The first curved portion (24b) extends along the circumference of the end of the insertion protrusion (24) in a smooth curved shape, and is formed in a curved manner by alternately connecting protruding parts and recessed parts having the same height or depth. At this time, it is preferable that the first curved portion (24b) is formed such that the protruding part and the recessed part each consist of a pair facing each other.

[0054]

[0055] The above operating member (30) is fixedly coupled to the inside of the main body (10) and is linked with the lifting member (50) to operate the lifting member (50) up and down.

[0056] As shown in FIGS. 2 and 3, the operating member (30) may include a base plate (32) that is seated on the bottom surface of the main body (10), an operating part (34) that is formed extending from the center of the base plate (32) and screw-coupled to the lifting member (50), and an elastic part (36) that is formed extending from the base plate (32) on the outside of the operating part (34) and provides elasticity to the rotation angle adjustment member (40). The base plate (32) is formed as a flat plate having a certain area and is inserted into the inner outer wall of the finishing plate (16) coupled to the main body (10), thereby restricting the rotation of the operating member (30) relative to the main body (10). Meanwhile, the elastic member (36) may be formed integrally with the operating member (30) as described above to elastically support the rotation angle adjustment member (40), or it may be separately injection molded and coupled to one side of the main body (10) or the operating member (30) to elastically support the rotation angle adjustment member (40).

[0057] The above operating part (34) is a cylinder with a hollow interior, and at least a portion of it is inserted into the internal space of the protective tube (20) while penetrating the through hole (12) of the main body (10), and a lifting member (50) is inserted into the interior and screw-coupled therein. An operating part locking projection (34a) is formed protruding from the outer circumference of the operating part (34) to be rotatably locked and coupled with the protective tube (20), and a lifting projection (34b) is formed on the inner circumference to be screw-coupled with the lifting screw thread (52a) formed on the lifting member (50). At this time, it is preferable that the operating part locking projection (34a) is formed extending along the outer circumference of the operating part (34), and that the lifting projection (34b) is formed protruding as a pair on the interior of the operating part (34).

[0058] The above elastic part (36) is formed on one side of the operating member (30) and is configured to elastically support the rotation angle adjustment member (40). It is composed of a first elastic part (36a) that operates elastically against the bottom of the operating member (30) and a second elastic part (36b) that operates elastically against the inner wall of the main body (10), thereby undergoing double elastic deformation. That is, when the rotation angle adjustment member (40) moves back and forth, the first elastic part (36a) and the second elastic part (36b) of the elastic part (36) are simultaneously elastically deformed or restored. This causes the force transmitted from the rotation angle adjustment member (40) or the self-restoring force of the elastic part (36) to be distributed to the first elastic part (36a) and the second elastic part (36b), thereby causing the elastic part (36) to elastically deform or be restored as a whole. Therefore, by preventing force from being concentrated on a part of the elastic part (36), the risk of damage can be reduced, and the rotation angle between the main body and the protective tube can be easily adjusted with little force, and the rotation angle adjustment function can be performed smoothly even after long-term use.

[0059] The first elastic member (36a) is positioned symmetrically on both sides of the operating member (34) and is formed to be inclined at a certain angle from the bottom of the operating member (30) toward its center, with at least a portion coming into contact with the outer circumference of the rotation angle adjustment member (40). The second elastic member (36b) is positioned symmetrically with respect to the operating member (34) and is formed to extend horizontally from the first elastic member (36a) toward the inner wall of the main body (10), with its end coming into contact with the inner wall. At this time, it is preferable that the end of the second elastic member (36b) be formed to protrude as a curved surface corresponding to the inner wall of the main body (10).

[0060] Meanwhile, the elastic part (36) may have a first guide part (36c) having a first diagonal surface (36c-1) formed therein and may be combined with a rotation angle adjustment member (40). The first guide part (36c) is configured to guide the reciprocating movement of the rotation angle adjustment member (40) relative to the elastic part (36). It is formed as a groove extending along the direction of reciprocating movement of the rotation angle adjustment member (40) between the first elastic part (36a) and the second elastic part (36b). The second guide part (46) formed on the rotation angle adjustment member (40) is fitted into the first guide part (36c), and a first diagonal surface (36c-1) is formed on the inner surface of the first guide part (36c), inclined at a certain angle from the upper surface of the second elastic part (36b) to the inner surface of the first elastic part (36a). At this time, the first diagonal surface (36c-1) may be formed entirely or partially on the inner surface of the first guide part (36c).

[0061] Additionally, at least one auxiliary tension member (36d) may be formed in the elastic member (36). The auxiliary tension member (36d) is configured to assist in the elastic deformation of the second elastic member (36b), is formed on the outer side adjacent to the first guide member (36c), and allows the second elastic member (36b) to be elastically deformed more easily when the rotation angle adjustment member (40) moves downward. The auxiliary tension member (36d) may be formed by bending at least a portion of the second elastic member (36b) so that they face each other and form a groove between them, or by perforating at least a portion of the second elastic member (36b) to form a hole.

[0062]

[0063] The above-mentioned rotation angle adjustment member (40) can be coupled to be reciprocally movable inside the main body (10). As shown in FIG. 4, the rotation angle adjustment member (40) is elastically supported by the elastic part (36) of the operating member (30) and moves up and down by the protective tube (20) to constantly adjust the rotation angle between the main body (10) and the protective tube (20).

[0064] The above-mentioned rotation angle adjustment member (40) has at least a portion coupled to the inside of the main body (10) so that rotation relative to the main body (10) is restricted, and a fitting hole (42) is formed in the center so that it is fitted while wrapping around the outside of the operating part (34) of the operating member (30), and the upper part can come into contact with the insertion protrusion (24) of the protective tube (20).

[0065] As shown in FIGS. 2 and 3, the rotation angle adjustment member (40) may have a second bend (44) formed therein to adjust the rotation angle between the main body (10) and the protective tube (20) together with the first bend (24b) of the protective tube (20). The second bend (44) protrudes from the inner wall of the rotation angle adjustment member (40) and comes into contact with the first bend (24b) inserted into the inside of the rotation angle adjustment member (40). The second bend (44) extends along the circumference of the inner wall of the rotation angle adjustment member (40) in a smooth curved shape, and is formed in a curved manner with alternating protruding parts and recessed parts having the same height or depth. At this time, it is preferable that the second bend (44) is formed such that the protruding part and the recessed part each form a pair and face each other.

[0066] Meanwhile, the rotation angle of the protective tube (20) relative to the main body (10) can be appropriately adjusted by changing the number of protruding and recessed portions formed in the first bend (24b) of the protective tube (20) and the second bend (44) of the rotation angle adjustment member (40). For example, if the protruding and recessed portions are formed as a pair facing each other, the rotation of the protective tube (20) relative to the main body (10) is restricted every 180 degrees, and if they are formed as two pairs facing each other, the rotation of the protective tube (20) relative to the main body (10) can be restricted every 90 degrees. Of course, if the rotation angle of the protective tube (20) relative to the main body (10) is changed as above, the lifting height of the stick-type cosmetic according to the rotation of the protective tube (20) can also be adjusted.

[0067] Additionally, the rotation angle adjustment member (40) may have a second guide part (46) having a second diagonal surface (46a) formed thereon and may be coupled with the elastic part (36) of the operating member (30). The second guide part (46) is configured to guide the reciprocating movement of the rotation angle adjustment member (40) relative to the elastic part (36). It is formed as a protrusion extending along the direction of reciprocating movement of the rotation angle adjustment member (40) on the outer wall of the rotation angle adjustment member (40). The second guide part (46) is fitted into the first guide part (36c) of the elastic part (36), and a second diagonal surface (46a) is formed on the outer surface of the second guide part (46) at a certain angle and contacts the first diagonal surface (36c-1) of the first guide part (36c). In addition, at least a portion of the second guide part (46) can be inserted into the guide insertion groove (14a) of the main body (10). At this time, the first diagonal surface (36c-1) and the second diagonal surface (46a) are formed to be inclined at a certain angle toward the center of the operating member (30) as the rotation angle adjustment member (40) is pressed, so that the elastic part (36) of the operating member (30) spreads outward and operates elastically.

[0068] The stick-type cosmetic container according to the present invention is exemplified by having the first guide part (36c) of the elastic part (36) formed as a groove and the second guide part (44) of the rotation angle adjustment member (40) formed as a protrusion so as to be fitted together, but is not limited thereto, and conversely, the first guide part (36c) may be formed as a protrusion and the second guide part (44) may be formed as a groove so as to be fitted together.

[0069]

[0070] The above lifting member (50) is linked with the operating member (30) with at least a portion located inside the protective tube (20), and when the protective tube (20) rotates relative to the main body (10), it moves up and down along the protective tube (20) to withdraw the stick-type cosmetic to the outside or insert it into the protective tube (20).

[0071] The above lifting member (50) may include a connecting part (52) that is screw-coupled to the operating member (30) and a plate part (54) to which a stick-type cosmetic is attached.

[0072] The above-mentioned coupling portion (52) is formed on one side of the lifting member (50) and can be inserted into the operating portion (34) of the operating member (30). A lifting screw thread (52a) is formed on the outer circumference of the coupling portion (52), and the lifting screw thread (52a) is screw-coupled with the lifting projection (34b) of the operating member (30) to guide the linear movement of the lifting member (50). That is, when the protective tube (20) rotates relative to the main body (10), the lifting member (50) located inside the protective tube (20) rotates together, and the lifting screw thread (52a) of the lifting member (50) moves along the lifting projection (34b) of the operating member (30), while the lifting member (50) moves up and down inside the protective tube (20).

[0073] Meanwhile, it is preferable that the lifting screw thread (52a) be formed at an appropriate angle along the outer circumference of the lifting member (50) to ensure smooth operation and travel distance of the lifting member (50). For example, if the angle of inclination of the lifting screw thread (52a) is relatively large, the travel distance of the lifting member (50) increases when the protective tube (20) rotates a certain angle relative to the main body (10), thereby increasing the lifting speed of the stick-type cosmetic; conversely, if the angle of inclination of the lifting screw thread (52a) is relatively small, the travel distance of the lifting member (50) decreases when the protective tube (20) rotates a certain angle relative to the main body (10), thereby decreasing the lifting speed of the stick-type cosmetic.

[0074] The above plate portion (54) is formed at one end of the coupling portion (52), and an outer wall of a certain height is formed along the edge portion, and a stick-type cosmetic can be inserted and filled inside.

[0075]

[0076] As described above, the stick-type cosmetic container according to the embodiment of the present invention controls the rotation angle of the protective tube (20) relative to the main body (10) by elastically reciprocating the rotation angle adjustment member (40) formed inside the main body (10), thereby making it convenient to use and allowing the rotation angle between the main body (10) and the protective tube (20) to be easily adjusted with little force. Furthermore, the elastic part (36) formed inside the main body (10) provides elasticity to the rotation angle adjustment member (50) by elastically deforming twice, so that the rotation angle adjustment function can be performed smoothly even after long-term use.

[0078] FIGS. 5 to 8 are drawings illustrating the use and operation process of a stick-type cosmetic container according to an embodiment of the present invention, and the use process of the stick-type cosmetic container according to an embodiment of the present invention will be explained with reference thereto.

[0079] FIG. 5 is a cross-sectional view illustrating the separation of an overcap from a main body according to an embodiment of the present invention, FIG. 6 is a perspective view illustrating the upward operation of a lifting member by rotating a protective tube relative to a main body according to an embodiment of the present invention, FIG. 7 is a cross-sectional view illustrating the elastic deformation of an operating member by a rotation angle adjustment member when the protective tube relative to a main body is rotated according to an embodiment of the present invention, FIG. 8 is a cross-sectional view illustrating the upward operation of a lifting member by rotating a protective tube relative to a main body according to an embodiment of the present invention.

[0080] In order to use a stick-type cosmetic container according to an embodiment of the present invention, as shown in FIG. 5, the overcap (60) is separated from the main body (10) to expose the protective tube (20) to the outside.

[0081] Subsequently, as shown in FIG. 6, when the protective tube (20) is rotated relative to the main body (10), the rotation angle adjustment member (40) installed inside the main body (10) is operated elastically by the elasticity of the elastic part (36), and the first bend (24b) of the protective tube (20) and the second bend (44) of the rotation angle adjustment member (40) become misaligned. That is, at the moment when the first bend (24b) of the protective tube (20) and the second bend (44) of the rotation angle adjustment member (40) become misaligned relative to the main body (10) while the protective tube (20) is rotated relative to the main body (10), the rotation angle adjustment member (40) is pushed downward by the protective tube (20), and the elastic part (36) elastically supporting the rotation angle adjustment member (40) undergoes elastic deformation. At this time, as shown in FIG. 7, the first elastic part (36a) of the elastic part (36) is elastically operated against the bottom of the main body (10), and at the same time, the second elastic part (36b) is elastically operated against the inner wall of the main body (10), thereby undergoing double elastic deformation.

[0082] When the protective tube (20) is continuously rotated further relative to the main body (10), the rotation angle adjustment member (40) installed inside the main body (10) returns to its original position by the self-restoring force of the elastic part (36), and the first bend (24b) of the protective tube (20) and the second bend (44) of the rotation angle adjustment member (40) engage. Accordingly, the protective tube (20) is rotated at a constant angle relative to the main body (10).

[0083] At the same time, the lifting member (50) located inside the protective tube (20) rotates together, and the lifting member (50) is lifted while screw-coupled to the operating member (30). That is, while the lifting member (50) is rotated by the protective tube (20), the operating member (30) is fixed within the main body (10), so that the lifting screw thread (52a) of the lifting member (50) moves along the lifting projection (34b) of the operating member (30), causing the lifting member (50) to move from the inside of the protective tube (20) upward.

[0084] Through the above process, as shown in FIG. 8, the stick-type cosmetic attached to the lifting member (50) is exposed to the outside through the inlet (22) of the protective tube (20), and the lifting length of the stick-type cosmetic is always maintained uniformly.
