Description

Technical Field

[0001] One aspect of the present disclosure relates to a sliding-type stick-shaped cosmetic container, and more specifically, to a sliding-type stick-shaped cosmetic container, wherein a stopper locking protrusion is formed inside a shell, and a first sliding stopper and a second sliding stopper are formed on a sliding member that slides inside the shell, so that a movement limiting structure for the sliding member can be formed inside the shell, thereby improving aesthetics, and wherein, due to the locking action between the stopper locking protrusion and the first sliding stopper and the second sliding stopper, the assembly work of the cosmetic stick holder and the operation of the sliding member can be easily achieved. Background Art

[0002] Generally, people use cosmetics to improve their appearance. The cosmetics can be divided into base makeup cosmetics for correcting the skin tone and spot makeup cosmetics for emphasizing specific parts of the body.

[0003] The base makeup cosmetics may include foundation, powder, BB cream, etc., and the point makeup cosmetics may include lipstick, lip gloss, eyeliner, etc.

[0004] According to its formula, the spot makeup cosmetics can be divided into liquid or gel cosmetics, stick cosmetics, etc. The stick cosmetics may be formed of solid cosmetics such as lipstick or foundation, and the tip portion of the stick cosmetics is applied to the use site.

[0005] The stick cosmetic is stored in a stick cosmetic container, and since the stick cosmetic is generally applied to the outside, the stick cosmetic container is manufactured to be easy to use externally.

[0006] A conventional stick-shaped cosmetic container includes: a shell body; a conduit coupled to the shell body and formed with a guide groove; a stick-shaped cosmetic holder coupled to the inside of the conduit and formed with a guide protrusion; a rotating tube coupled to the outside of the conduit and having an inner wall formed with a spiral groove; and a cover coupled to the upper portion of the shell body.

[0007] When applying makeup using a conventional stick-shaped cosmetic container, the user holds the rotating tube with one hand and the housing body with the other hand, and then rotates the rotating tube and the housing body in opposite directions to guide the guide protrusion of the stick-shaped cosmetic holder in an upward direction along the spiral groove of the rotating tube and the guide groove of the guide tube. In this case, the stick-shaped cosmetic inserted into the stick-shaped cosmetic holder can also move upward, so that the user can apply makeup.

[0008] However, since the conventional stick-shaped cosmetic container has a structure that converts rotational motion into linear motion, the number of components may increase and the structure may be complicated, which leads to an increase in product cost, and a long assembly time may be required during production, which leads to a decrease in productivity.

[0009] In addition, in order to use conventional stick cosmetics when going out, the user needs to use both hands, because the user holds the housing body with one hand and holds the rotating tube with the other hand to rotate the rotating tube, so there is a problem of discomfort when the user looks at the hand mirror to put on makeup.

[0010] In order to solve the above problem, a lipstick is disclosed in Korean Utility Model Registration No. 20-0220242. According to the above related art, a through hole is formed at the upper part of the shell body, a bed-shaped elastic plate is formed at one side wall of the inner cylinder accommodated in the shell body, the elastic plate is fastened by a guide claw formed at the inner peripheral wall of the shell body and is guided while being inserted into a guide groove, an operating part is attached to the middle part of the elastic plate, the operating part is guided while being inserted into a guide extension hole formed in one side peripheral wall of the shell body, and the outer end of the elastic plate serves as a plug, the front end of the plug is fitted in a fitting groove formed at one side of the through hole and locked with the fitting groove.

[0011] The above-mentioned related technology is an automatic lipstick, wherein the operating part formed at a side wall of the shell body moves along the guide extension hole to open the plug of the through hole, and at the same time, the inner cylinder is coupled to the lipstick to move upward to extend out of the shell body.

[0012] However, since the lipstick may be pushed down when using the lipstick, the above related art is inconvenient to use. In addition, during storage, the lipstick is easily exposed in the bag due to contact with other items, so that the inside of the bag may become dirty or the lipstick may break.

[0013] In order to solve the above problems, the applicant disclosed a sliding type lipstick container in utility model registration number 20-0478730, wherein a button and a button guide slit equipped with the button are formed on the outer peripheral surface of the shell, a sliding member for moving the cosmetic stick up and down is connected to the boss of the button and the lower end of the cosmetic stick holder, control protrusions are provided at the upper and lower parts of the button guide slit, and a friction protrusion is formed on the boss of the button, the friction protrusion interferes with the vertical movement of the button due to friction with the button guide slit, thereby preventing the cosmetic stick from being pressed down when operating the lipstick container and maintaining soft sensitivity when operating the lipstick container.

[0014] However, the above-mentioned related art has a structure in which the cosmetic stick is stopped by the friction protrusion of the button and the control protrusion formed on the button guide slit of the housing, and thus the control protrusion is exposed to the outside of the housing, thereby reducing aesthetics.

[0015] In addition, the above-mentioned related art needs to form a friction protrusion and an elastic space in a narrow space of the button boss, so that the structure of the button may become complicated, thereby reducing productivity.

[0044] In the following, reference will be made to Figures 1 to 3 DETAILED DESCRIPTION A stick-type stick cosmetic container according to one aspect of the present disclosure is described.

[0045] Figure 1 is a perspective view of a stick-shaped cosmetic container according to one aspect of the present disclosure, Figure 2 is an exploded perspective view of a stick-shaped cosmetic container according to one aspect of the present disclosure, and Figure 3 is a cross-sectional view of a stick-shaped cosmetic container according to one aspect of the present disclosure.

[0046] As shown in the figures, the present disclosure may include a housing 10 , a sliding member 20 , a button 30 , a cosmetic stick holder 40 , a conduit 50 , and a cover 60 .

[0047] The housing 10 serves as a handle for a user to grip, and the sliding member 20 and the cosmetic stick holder 40 are accommodated inside the housing 10 .

[0048] like Figure 2As shown, the housing 10 may include an inner shell 12 and an outer shell 14 surrounding the outside of the inner shell 12 .

[0049] The inner shell 12 is divided into a first inner shell 12a and a second inner shell 12b, which are divided into two in the longitudinal direction and coupled to each other. In the drawings showing a stick-shaped cosmetic container according to one aspect of the present disclosure, the first inner shell 12a and the second inner shell 12b are coupled to each other by a protrusion-groove coupling manner, but the present disclosure is not limited thereto and may be changed to adopt various coupling schemes.

[0050] The guide part 13 may be formed inside the first inner case 12 a and the second inner case 12 b , and the guide part 13 guides the sliding member 20 so that the sliding member 20 may stably slide without shaking.

[0051] The guide portion 13 may include a first guide portion 13a and a second guide portion 13b. The first guide portion 13a and the second guide portion 13b may be spaced apart from each other by a predetermined distance and may be arranged side by side in the longitudinal direction within the first inner shell 12a and the second inner shell 12b. As shown in the figure, the guide portion 13 may be formed at both the first inner shell 12a and the second inner shell 12b, or may be formed at only one of the first inner shell 12a and the second inner shell 12b.

[0052] The first guide portion 13a may include: a first straight portion 13a-1, which constitutes an outer wall of the inner shell 12; a curved portion 13a-2, which is connected to one end of the first straight portion 13a-1 in a curved shape; and a second straight portion 13a-3, which is linearly connected to one end of the curved portion 13a-2 while facing the second guide portion 13b. In addition, the second guide portion 13b may be formed in a shape corresponding to the second straight portion 13a-3 of the first guide portion 13a. The sliding member 20 may be inserted between the second straight portion 13a-3 of the first guide portion 13a and the second guide portion 13b, and the sliding member 20 may be installed on the first straight portion 13a-1 and the curved portion 13a-2 of the first guide portion 13a.

[0053] In addition, the sliding member insertion groove 16 may be formed on one surface of the inner case 12 , that is, the outer surface of the first guide portion 13 a formed on the first and second inner cases 12 a and 12 b and the sliding member 20 may be inserted into the sliding member insertion groove 16 .

[0054] In addition, the stopper locking protrusion 15 may protrude from one surface of the first guide portion 13a or the second guide portion 13b. The stopper locking protrusion 15 may be locked with the first sliding stopper 22 and the second sliding stopper 24 of the sliding member 20 to be described below to limit the movement of the sliding member 20. In the accompanying drawings showing a stick-shaped cosmetic container according to one aspect of the present disclosure, the stopper locking protrusion 15 is disposed between the curved portion 13a-2 and the second straight portion 13a-3 of the first guide portion 13a, and protrudes toward the second guide portion 13b. However, the position of the stopper locking protrusion 15 may not be limited to the above-mentioned position, and the stopper locking protrusion 15 may be located at various positions as long as the stopper locking protrusion 15 can be locked with the first sliding stopper 22 and the second sliding stopper 24 of the sliding member 20.

[0055] The outer shell 14 is coupled to the inner shell 12 while surrounding the outside of the inner shell 12. The outer shell 14 may have a cylindrical shape or a polygonal column shape having one end opened.

[0056] In addition, a button guide slit 14a may be formed on one side surface of the housing 14. The button guide slit 14a may extend along the longitudinal direction of the housing 14, and the button 30 may be coupled to the button guide slit 14a so that the button 30 can slide vertically, that is, linearly move in the longitudinal direction of the housing 14.

[0057] The sliding member 20 may have a plate shape having a narrow width and a long length, and may be installed inside the housing 10 to move the cosmetic stick holder 40 up and down while sliding by the operation of the button 30. In addition, the sliding member 20 may have predetermined elasticity so that the sliding member 20 may be coupled inside the housing 10 in a bent state.

[0058] In detail, the sliding member 20 is coupled to the guide portion 13 of the inner shell 12 in such a manner that a portion of the sliding member 20 is inserted between the first guide portion 13a and the second guide portion 13b and the remaining portion of the sliding member 20 is in close contact with the outer peripheral surfaces of the first straight portion 13a-1 and the curved portion 13a-2 of the first guide portion 13a.

[0059] The button coupling hole 21 may be formed in one end of the sliding member 20, and the button 30 may be coupled to the button coupling hole 21. The holder coupling portion 23 may be formed on the other end of the sliding member 20, and the cosmetic stick holder 40 may be coupled to the holder coupling portion 23. The button coupling hole 21 may be located in the sliding member insertion groove 16 of the inner case 12 and may be exposed to the outside through the button guide slit 14a of the outer case 14, and the coupling protrusion 23a may be formed on the outer peripheral surface of the holder coupling portion 23.

[0060] The sliding member 20 may be provided with a first sliding stopper 22 and a second sliding stopper 24 spaced apart from each other by a predetermined distance. The first sliding stopper 22 and the second sliding stopper 24 may protrude in the width direction of the sliding member 20, and may be locked with the stopper locking protrusion 15 of the housing 10 to restrict the movement of the sliding member 20. That is, when the cosmetic stick holder 40 is located at the highest position, the first sliding stopper 22 may move the button 30 downward to fix the sliding member 20, and when the cosmetic stick holder 40 is located at the lowest position, the second sliding stopper 24 may move the button 30 upward to fix the sliding member 20.

[0061] In other words, the stopper locking protrusion 15 may be formed on the guide portion 13 of the housing 10, and the first sliding stopper 22 and the second sliding stopper 24 facing the stopper locking protrusion 15 may be formed on one surface of the sliding member 20. Therefore, when the sliding member 20 slides in the housing 10, the first sliding stopper 22 and the second sliding stopper 24 of the sliding member 20 move over the stopper locking protrusion 15 or lock with the stopper locking protrusion 15, so that the movement of the sliding member 20 can be limited to a predetermined position. Therefore, the movement limiting structure of the sliding member 20 may not be exposed to the outside, thereby improving the aesthetics and simplifying the structure so that the productivity can be improved.

[0062] Meanwhile, during the assembly process of the stick-shaped cosmetic container, as Figure 6 As shown, the button 30 is completely lowered, and the slide member 20 is slid upward, and then the cosmetic stick holder 40 is coupled to the holder coupling portion 23 of the slide member 20. In this case, the slide member 20 is pressed by the cosmetic stick holder 40 so as to push the slide member 20 downward into the housing 10. In this regard, according to one aspect of the present disclosure, when the button 30 is located at the lowest position, the first slide stopper 22 formed on the slide member 20 moves over the stopper locking protrusion 15 formed on the housing 10 to fix the slide member 20 so as to prevent the slide member 20 from being pushed downward into the housing 10 by the cosmetic stick holder 40 when the cosmetic stick holder 40 is coupled to the slide member 20, thereby making it easy to assemble the cosmetic stick holder 40 to the slide member 20.

[0063] In addition, when it is necessary to pull out the cosmetic stick holder 40 by moving the button 30 located at the highest position downward to use the stick-shaped cosmetic container, the cosmetic stick holder 40 may slide backward. The backward sliding refers to a phenomenon that when the consumer slidably moves the slide member 20 and the cosmetic stick holder 40 coupled to the slide member 20 in an upward direction by pushing the button 30 downward, the cosmetic stick holder 40 tends to move downward again due to the restoring property of the slide member 20 bent in the housing 10. In this regard, according to one aspect of the present disclosure, as Figure 7 As shown, when the button 30 located at the highest position moves downward, the second slide stopper 24 formed on the slide member 20 moves over the stopper locking protrusion 15 formed on the housing 10. Therefore, the slide member 20 deformed in the bent state may move backward due to the restoring force, thereby preventing the cosmetic stick holder 40 from moving downward again.

[0064] In addition, if Figure 2 As shown, in the moving direction of the sliding member 20, that is, in the longitudinal direction of the sliding member 20, a tension groove 26 may be formed on the sliding member 20. Due to the tension groove 26, when the sliding member 20 moves up and down in a bent state, soft tension may be induced. In other words, since the sliding member 20 is installed in a bent state and slidably moves through the guide portion 13 formed in the housing 10, when the elongated coring groove is formed in one surface of the sliding member 20, the sliding member 20 may slidably move while being naturally and smoothly bent.

[0065] In addition, the sliding member 20 may be formed of a synthetic resin including at least one selected from the group consisting of PP (polypropylene), TPE (thermoplastic elastomer), LDPE (low-density polyethylene), and HDPE (high-density polyethylene).

[0066] Advantageously, the sliding member 20 may be formed of a mixture containing LDPE (low-density polyethylene) and HDPE (high-density polyethylene), wherein the content of LDPE (low-density polyethylene) is 55% by weight to 65% by weight and the content of HDPE (high-density polyethylene) is 35% by weight to 45% by weight. Most advantageously, the content of LDPE (low-density polyethylene) is 60% by weight and the content of HDPE (high-density polyethylene) is 40% by weight.

[0067] In the case of a mixture containing PP (polypropylene) and TPE (thermoplastic elastomer), the injection molding performance is excellent, but there may be a problem that tearing of the weld line (a defect in the form of a line generated at a point where molten resin flows meet) may occur. Therefore, there is a disadvantage that the thickness of the tension groove 26 of the sliding member 20 may increase.

[0068] In addition, if the content of LDPE is less than 55% by weight, fluidity may be reduced during injection molding, thus requiring over-packing injection molding. In this case, there is a problem in that burrs (thin fin-shaped redundant parts) are seriously generated when the slider is opened due to over-packing injection molding. In addition, when the content of LDPE exceeds 65% by weight, the flexibility is too high, and thus it is not suitable for the sliding member 20 according to one aspect of the present disclosure.

[0069] In addition, if the content of HDPE is less than 35% by weight, the flexibility is too high and thus it is not suitable for the sliding member according to one aspect of the present disclosure, and if the content of HDPE exceeds 45% by weight, the injection molding performance is reduced and thus mass production is impossible. In addition, when the content of HDPE exceeds 45% by weight, the flexibility is too low and thus it is not suitable for the sliding member according to one aspect of the present disclosure.

[0070] Examples 1 to 9. Preparation of a sliding member formed of a mixture containing LDPE and HDPE

[0071] In order to find a suitable composition ratio of low density polyethylene (LDPE) and high density polyethylene (HDPE), the sliding member 20 formed of a mixture including low density polyethylene (LDPE) and high density polyethylene (HDPE) was prepared while changing the contents of low density polyethylene (LDPE) and high density polyethylene (HDPE).

[0072] The sliding member is prepared by injection molding mixtures containing 30% by weight LDPE and 70% by weight HDPE, 35% by weight LDPE and 65% by weight HDPE, 40% by weight LDPE and 60% by weight HDPE, 45% by weight LDPE and 55% by weight HDPE, 50% by weight LDPE and 50% by weight HDPE, 55% by weight LDPE and 45% by weight HDPE, 60% by weight LDPE and 40% by weight HDPE, 65% by weight LDPE and 35% by weight HDPE, and 70% by weight LDPE and 30% by weight HDPE, respectively.

[0073] LG LUTENE MB9205 was used as LDPE, and Lotte J220 was used as HDPE.

[0074] The composition ratios of LDPE and HDPE of Examples 1 to 9 are shown in Table 1 below.

[0075]

[0076]

[0077] Comparative Example 1. Preparation of a sliding member formed of a mixture including polypropylene (PP) and thermoplastic elastomer (TPE)

[0078] A sliding member 20 formed of a mixture containing polypropylene and a thermoplastic elastomer was prepared. The sliding member was prepared by injection molding a mixture containing 70% by weight of PP and 30% by weight of TPE. Lotte J560S was used as PP, and Keyflex 8402 was used as TPE.

[0079] Experimental Example 1. Evaluation of sliding member

[0080] The weld line tearing phenomenon, injection molding performance, fluidity, and elasticity were evaluated by the sliding members obtained from Examples 1 to 9 and Comparative Example 1, respectively.

[0081] The weld line tearing phenomenon was evaluated based on the frequency of defect occurrence, and the injection molding performance, flowability, and flexibility were evaluated by sensory evaluation. The comparison objects and evaluation items are shown in Table 2.

[0082]

[0083]

[0084]

[0085] As shown in Table 2, Examples 1 to 5 have problems in mass production due to poor injection molding performance and fluidity, and Example 9 has excellent injection molding performance and fluidity, but insufficient flexibility. In addition, Comparative Example 1 using PP and TPE exhibits sufficient injection molding performance, fluidity and flexibility, but frequent tearing of the weld line occurs. In addition, Example 6 using 55% by weight of LDPE and 45% by weight of HDPE, Example 7 using 60% by weight of LDPE and 40% by weight of HDPE, and Example 8 using 65% by weight of LDPE and 35% by weight of HDPE are found to be suitable for the sliding member according to one aspect of the present disclosure. In other words, in terms of injection molding performance, fluidity, flexibility and tearing of the weld line, when the sliding member according to one aspect of the present disclosure is formed by a mixture containing 55% by weight to 65% by weight of LDPE and 35% by weight to 45% by weight of HDPE, it is suitable.

[0086] The button 30 may be coupled to one side of the slide member 20, and the slide member 20 may slide by the operation of the button 30. That is, the button 30 may linearly move upward or downward along the button guide slit 14a of the housing 14 to slidably move the slide member 20.

[0087] The mounting portion 32 may be formed on the back side of the button 30, that is, on the opposite side of the portion directly touched by the user's finger. The mounting portion 32 is fixedly coupled to the button coupling hole 21 of the sliding member 20 located in the sliding member insertion groove 16 of the inner case 12 by passing through the button guide slit 14a of the outer case 14.

[0088] The cosmetic stick holder 40 may be coupled to the other side of the sliding member 20 , and may be pulled out to the outside or retracted from the outside while being moved up and down by the sliding member 20 .

[0089] The cosmetic stick S may be attached to the cosmetic stick holder 40, and the coupling portion 42 may protrude from opposite sides of the cosmetic stick S so that the coupling portion 42 may be fixedly coupled to the holder coupling portion 23 of the sliding member 20. A coupling groove 42a may be formed on an outer peripheral surface of the coupling portion 42, and the coupling protrusion 23a of the sliding member 20 may be fitted into the coupling groove 42a.

[0090] The guide tube 50 may have an open upper portion and a lower portion, and may be coupled to the housing 10 to guide the up / down movement of the cosmetic stick holder 40. More specifically, as Figure 3 As shown, the lower portion of the conduit 50 can be fixedly coupled while being inserted between the inner shell 12 and the outer shell 14 of the housing 10, and a mounting protrusion 52 can be formed on the outer peripheral surface of the conduit 50 and mounted on a mounting claw 14b formed at the upper end of the outer shell 14.

[0091] The cover 60 may be detachably mounted while wrapping around the conduit 50 to open and close the conduit 50. A mounting groove 66 may be formed on the lower inner circumferential surface of the cover 60, and a detachable protrusion 56 may be provided on the outer circumferential surface of the conduit 50 to be detachably coupled thereto.

[0092] In the drawings showing a stick-shaped cosmetic container according to one aspect of the present disclosure, the cap 60 is shown as being fastened to the conduit 50 by protrusions and grooves, but the present disclosure is not limited thereto. The cap 60 may be fastened by various coupling configurations such as undercut coupling, press-fit coupling, and screw coupling. In addition, the cap 60 may open and close the conduit 50 while being fastened to the housing 10 instead of the conduit 50.

[0093] Figures 4 to 71 is a view showing the assembly work and use of a stick-shaped cosmetic container according to one aspect of the present disclosure. Figures 4 to 7 The assembly work and the use method of the stick-shaped cosmetic container according to one aspect of the present disclosure are described.

[0094] Figure 4 is a cross-sectional view showing a state in which a cap of a stick-shaped cosmetic container according to one aspect of the present disclosure is separated, Figure 5 is a cross-sectional view showing an operation state of a button of a stick-shaped cosmetic container according to one aspect of the present disclosure, Figure 6 is a cross-sectional view showing a state in which a cosmetic stick holder according to one aspect of the present disclosure is coupled to a sliding member of a stick-shaped cosmetic container, and Figure 7 is a cross-sectional view showing a state in which a cosmetic stick holder of a stick-shaped cosmetic container according to one aspect of the present disclosure is lifted.

[0095] First, if Figure 2 As shown, while bending the sliding member 20, the sliding member 20 is inserted between the first guide portion 13a and the second guide portion 13b formed inside the first inner shell 12a or the second inner shell 12b, and then the first inner shell 12a and the second inner shell 12b are coupled to each other. In this case, the button coupling hole 21 of the sliding member 20 is exposed to the outside of the inner shell 12, and the retainer coupling portion 23 is located at the center of the inner shell 12.

[0096] Next, the sliding member 20 exposed to the outside of the inner case 12 is pressed downward so that the sliding member 20 is in close contact with the sliding member insertion groove 16 of the inner case 12, and the inner case 12 is inserted into the outer case 14 and coupled with the outer case 14. In this case, the button coupling hole 21 of the sliding member 20 is exposed to the outside through the button guide slit 14a of the outer case 14.

[0097] Then, the button 30 is mounted on the housing 14 , and the mounting portion 32 of the button 30 is coupled with the button coupling hole 21 of the slide member 20 by passing through the button guide slit 14 a of the housing 14 .

[0098] Thereafter, the conduit 50 is coupled to the upper portions of the inner and outer shells 12 and 14 while inserting the lower portion of the conduit 50 between the inner and outer shells 12 and 14. In this case, the mounting protrusion 52 of the conduit 50 is mounted on the mounting claw 14b of the outer shell 14.

[0099] Next, if Figure 6 As shown, after the button 30 is lowered to the lowermost end, the cosmetic stick holder 40 is inserted into the opened upper portion of the guide tube 50 , thereby fastening the coupling portion 42 of the cosmetic stick holder 40 to the holder coupling portion 23 of the slide member 20 .

[0100] In this state, the cosmetic stick S is attached to the cosmetic stick holder 40. Figure 6 As shown in the partially enlarged portion of , since the first sliding stopper 22 formed on the sliding member 20 moves over the stopper locking protrusion 15 formed on the shell 10 and is fixed to the stopper locking protrusion 15, the sliding member 20 can be prevented from being pushed downward into the shell 10 by the cosmetic stick holder 40.

[0101] Finally, the duct 50 is fastened by covering the duct 50 with the cap 60 , thereby completing the assembly work of the stick-shaped cosmetic container according to one aspect of the present disclosure.

[0102] When the stick-shaped cosmetic container according to one aspect of the present disclosure assembled as described above is used, Figure 4 As shown, the cover 60 is removed from the housing 10 to expose the conduit 50 to the outside.

[0103] Then, if Figure 5 As shown, when the button 30 is pressed downward, one side of the sliding member 20 connected to the button 30 slides downward, and the other side of the sliding member 20 moves upward, while pushing the cosmetic stick holder 40 upward to pull the cosmetic stick S out.

[0104] In this case, if Figure 7 As shown, when the button 30 is pressed downward, the second slide stopper 24 formed on the slide member 20 moves over the stopper locking protrusion 15 formed on the housing 10. Therefore, the slide member 20 deformed in a bent shape moves backward due to its restoring force, thereby preventing the cosmetic stick holder 40 from moving downward again.
