Description

Technical Field

[0001] This utility model relates to solid applicators, and more specifically to refillable solid cosmetic applicators that can be refilled with solids. Background Technology

[0002] Various cosmetics are used according to their type or material, such as solid, liquid, gel, powder, etc., and various types of cosmetic applicators, including cosmetic blocks, are widely used. Among them, long cylindrical applicators or pencil-shaped applicators are manufactured for lipsticks, lip glosses, and eyeliner gels.

[0003] Pencil applicators are typically constructed with a rod-shaped solid cosmetic block attached to a liftable component, and are configured to allow the cosmetic block to move up and down within the applicator by rotating a portion of the applicator.

[0004] However, pencil-type cosmetic applicators currently on the market typically have a diameter of 1 cm or larger, and therefore, solid cosmetic blocks usually have a larger diameter. Rod-shaped solid cosmetic blocks with small diameters or elongated shapes may have the problem of being prone to breakage during use, and additionally, with small-diameter cosmetic applicators, it is not easy to design a lifting mechanism or assemble the applicator.

[0031] Figure 1 a is a perspective view illustrating a refillable solid applicator according to an embodiment of the present disclosure. Figure 1 b is a perspective view illustrating a refillable solid applicator according to an embodiment of the present disclosure. Figure 2 The illustration shows a cross-sectional view of a refillable solid applicator, and Figure 3 This is an exploded 3D view of a refillable solid applicator. Figure 4 This is a perspective view illustrating the body 10 and guide ring 50 of the applicator according to an embodiment. Figure 5 The diagram illustrates a view of the sliding member 40 and the adjusting portion 30 according to an embodiment, and Figure 6 View a illustrates the sliding member 40 and the adjusting part 30, and Figure 6 b is a view illustrating the sliding member 40 and the adjusting part 30.

[0032] Reference Figure 1 a and Figure 1 b. A refillable solid applicator (hereinafter referred to as "applicator") according to an embodiment may include a body 10 and a cap 20 separable from the body 10, and the applicator may have an adjustment portion 30 rotatably connected to the lower end of the body 10.

[0033] The cap-shaped member 20 is removably attached to the upper portion of the main body 10. Unless otherwise specified, the terms "upper portion," "upper end," or "front portion" used in the specification to explain the positional relationship between the components refer to the direction in which the cap-shaped member 20 is attached relative to the main body 10, while the terms "lower portion," "lower end," or "rear portion" refer to the direction in which the adjusting portion 30 is attached. Furthermore, the "rising" or "forward" movement of the cylindrical member 60 means that the cylindrical member 60 moves forward relative to the main body 10, while the "falling" or "retracting" movement means that the cylindrical member 60 moves backward relative to the main body 10.

[0034] A cylindrical member 60, including a solid block 61, is inserted into the main body 10. To use the solid block 61, the user can detach the cap-shaped member 20 from the main body 10 and then twist the solid block 61 out of the main body 10 in an upward direction by rotating the adjusting part 30, and then use the solid block 61. For example, the solid block 61 can be a solid cosmetic (e.g., lipstick, eyeliner, etc.) or a writing instrument (e.g., crayon, highlighter), but is not limited to these, and can be any type of solid block.

[0035] Reference Figure 2 and Figure 3 According to the embodiments, the refillable solid applicator may include a cylindrical body 10, a cap-shaped member 20 removably attached to the upper portion of the body 10, an adjustment portion 30 rotatably connected to the lower portion of the body 10, and a sliding member 40 and a cylindrical member 60 disposed in the body 10.

[0036] The body 10 is a cylindrical member having a perforation formed from its upper end to its lower end. In an embodiment, the body 10 can be made of a plastic material and can be manufactured by injection molding. Preferably, the body 10 can be produced using materials of different colors by a double injection molding method. For example, as... Figure 2 As shown, the body 10 may include an inner component 11 and an outer component 12 of different colors, and in this case, the body 10 may be manufactured by: producing the inner component 11 by injection in a first cavity of a molding apparatus, and then transferring the inner component to a second cavity, and producing the outer component 12 by injection over the inner component 11.

[0037] The internal space of the main body 10, that is, the internal space extending from the upper end to the lower end of the main body 10, can be divided into at least two internal spaces with different diameters. For example... Figure 2 , Figure 3 and Figure 4 As shown, a first internal space with a predetermined first diameter is formed from the upper end of the main body 10 to approximately the middle portion, and a second internal space with a second diameter larger than the first diameter is formed from the middle portion to the lower end. A stepped portion 15 is formed in the region where the first internal space and the second internal space are connected to each other due to the difference in diameter.

[0038] A guide ring 50 can be disposed on the stepped portion 15. That is, the outer diameter of the guide ring 50 is equal to the second diameter, and therefore, the guide ring 50 can be inserted from the lower end of the body 10 and can sit on the stepped portion 15. The guide ring 50 is an annular member having a perforation formed in its center, and the outer diameter of the guide ring 50 is equal to the second diameter, and the cross-sectional shape of the perforation formed in the center is the same as the cross-sectional shape of the threaded portion 41 of the sliding member 40, which will be described below.

[0039] Reference Figure 4 An anti-rotation protrusion 15b may be formed on the step portion 15. That is, the region 15a of the step portion 15 where the anti-rotation protrusion 15b is not formed may have a second diameter, and the diameter of the region where the anti-rotation protrusion 15b is formed may be smaller than the second diameter and may be equal to or greater than the first diameter.

[0040] The outer periphery of the guide ring 50 may have a shape that engages with the shape of the anti-rotation protrusion 15b. For example... Figure 4 As shown, the outer periphery of the guide ring 50, having a relatively large diameter region 50a, has a second diameter and sits on the area of ​​the stepped portion 15 of the body 10 where the anti-rotation protrusion 15b is not formed. The region of the guide ring 50, having a relatively small diameter, is configured to contact the anti-rotation protrusion 15b. Therefore, when the guide ring 50 sits on the stepped portion 15 of the body 10, the guide ring 50 does not rotate and is fixed.

[0041] Return to reference Figure 2 and Figure 3 The cap-shaped member 20 is a component removably attached to the upper end of the body 10. In one embodiment, the cap-shaped member 20 may be made of a plastic material and may be manufactured by a double injection molding method. For example, the cap-shaped member 20 may be formed from an inner member 21 and an outer member 22 of different colors and may be manufactured simultaneously by a double injection molding method. An inner cap-shaped member 25 may be additionally attached to the interior of the cap-shaped member to seal the interior space of the body 10 relative to the exterior.

[0042] The adjusting portion 30 is a component for adjusting the upward and downward movements of the sliding member 40, and the adjusting portion 30 is rotatably connected to the lower end of the main body 10. In an embodiment, the adjusting portion 30 may include a receiving tube 31 and a handle 32, the receiving tube 31 having a relatively small diameter and receiving a portion of the sliding member 40, and the handle 32 having a relatively large diameter and protruding downward from the lower end of the main body 10.

[0043] The receiving tube 31 is a cylindrical member having an open upper end to partially receive the sliding member 40, and having an outer diameter equal to the second diameter of the body 10. The receiving tube 31 and the handle 32 can be integrally formed with each other, or they can be manufactured separately and then joined together. A recessed portion 37 may be formed along the outer periphery near the lower end of the receiving tube 31, and a protrusion 17 may be formed on the inner diameter side of the body 10. Figure 4 The adjustment portion 30 is inserted into the body 10 from the lower portion of the body 10, and the protrusion 17 is inserted into the recess 37, so that the adjustment portion 30 is rotatably connected to the body 10 without being released from the body 10.

[0044] The sliding member 40 is a component disposed within the internal space of the main body 10 and is screwed onto the adjusting portion 30 to rise and fall by rotation of the adjusting portion 30. In one embodiment, the sliding member 40 may include a threaded portion 41 and a fastening portion 42. The threaded portion 41 may be formed in a rod shape and may have threads formed on its outer periphery, and the fastening portion 42 may extend from the upper end of the threaded portion 41 and may have a receiving recess to allow one end of the cylindrical member 60 to be removably engaged to the receiving recess. The threaded portion 41 can be inserted into the receiving tube 31 of the adjusting portion 30 by a screw-on engagement method, such that the sliding member 40 is fastened to the adjusting portion 30.

[0045] The threaded portion 41 of the sliding member 40 has a cylindrical shape and has threads formed on its outer periphery. In a preferred embodiment, the threaded portion 41 may have a flat portion 43 formed on its outer periphery along the longitudinal direction and without threads. Figure 5 and Figure 6 As shown in Figure a, a pair of planar portions 43 facing each other can be formed along the longitudinal direction on opposite outer peripheries of the threaded portion 41, and can have flat, unthreaded surfaces. Figure 4 As shown, the inner circumference of the guide ring 50 may have the same cross-sectional shape as the threaded portion 41. That is, it will be understood that the inner circumference of the guide ring 50 includes a region 51a that contacts the threaded portion 41 and a region 51b that contacts the planar portion 43.

[0046] The cylindrical member 60 may include a solid block 61 and a retainer 62. The solid block 61 may be a solid cosmetic such as lipstick and may have a lower end that is inserted into and supported in the retainer 62. A receiving recess may be formed on the upper portion of the retainer 62 for receiving the lower end of the solid block 61, and a protrusion may be formed on the lower portion of the retainer 62 for removably inserting into the fastening portion 42 of the sliding member 40.

[0047] The following will refer to Figure 5 and Figure 6 a and Figure 6 b describes in detail the construction of the adjusting part 30 and the sliding member 40.

[0048] In the embodiment, grooves 35 and 45 may be formed in the receiving tube 31 of the adjusting portion 30 and the threaded portion 41 of the sliding member 40, respectively. Figure 5 As shown, groove 35 can be formed at a predetermined depth d1 on the upper end of the receiving tube 31 of the adjusting portion 30, and groove 45 can be formed at a predetermined depth d2 on the lower end of the threaded portion 41 of the sliding member 40. The depths of grooves 35 and 45 can vary depending on the specific embodiment, and can be, for example, between a few millimeters and 1 centimeter.

[0049] The threaded portion 41 inserted into the receiving tube 31 is screwed onto the inner surface of the receiving tube 31, and to achieve this, a thread 33 can be formed in the receiving tube 31 at a predetermined length. In a preferred embodiment, the thread 33 formed in the receiving tube 31 can be formed from the front end of the receiving tube 31 at the length d1 of the groove 35, or it can be formed at a length shorter than d1. Therefore, during the assembly process of the applicator, when the operator pushes the threaded portion 41 toward the receiving tube 31, the diameter of each end of the receiving tube 31 and the threaded portion 41 may change slightly due to the presence of the grooves 35, 45, until the lower end of the threaded portion 41 is inserted into the receiving tube 31 to a predetermined depth d1. Thus, the threaded portion 41 is easily inserted into the receiving tube 31 simply by pushing, and thereafter, by rotating the adjusting portion 30 relative to the sliding member 30, the threaded portion 40 is further inserted into the receiving tube 31, and thus, the sliding member 40 and the adjusting portion 30 can be easily and quickly assembled when assembling the applicator.

[0050] In a preferred embodiment, the sliding member 40 may include a protrusion 46 extending radially to a predetermined height from the lower end of the threaded portion 41 to prevent the sliding member 40 from being released from the adjusting portion 30. The diameter of the front end of the threaded portion 41 with the protrusion 46 may be greater than the maximum diameter of the thread of the threaded portion 41, and may be equal to or less than the inner diameter of the region of the receiving tube 31 where the thread 33 is not formed. Alternatively, considering that the diameter of the end of the threaded portion 41 is slightly reduced due to the presence of the groove 45, the diameter of the end of the threaded portion 41 with the protrusion 46 may be slightly greater than the inner diameter of the region of the receiving tube 31 where the thread 33 is not formed.

[0051] When the applicator is assembled or used and the tubular part is replaced, the applicator according to this disclosure can have the following advantages.

[0052] First, during the assembly of the applicator, the sliding member 40 is inserted into the interior space of the body 10 from the front portion, and then the sliding member 40 is pushed from the front portion to the rear portion, so that the end of the threaded portion 41 (e.g., the end with the groove 45) protrudes to the outside of the rear end portion of the body 10.

[0053] Subsequently, the guide ring 50 is inserted into the threaded portion 41, and the threaded portion 41 is inserted into the receiving tube 31 of the adjusting portion 30. In this case, since the guide ring 50 is a component separate from the main body 10, the sliding member 40 is first inserted into the main body 10, and then the guide ring 50 is inserted into the threaded portion 41. Therefore, by matching the cross-sectional shapes of the guide ring 50 and the threaded portion 41, the guide ring 50 and the threaded portion 41 can be easily and quickly connected to each other.

[0054] In this case, the diameter of the end can be flexibly changed due to the grooves 35 and 45, so that the sliding member 40 can be easily inserted into the receiving tube 31, and once inserted, the sliding member 40 will not be released from the adjusting part 30 due to the presence of the protrusion 46.

[0055] As described above, the threaded portion 41 is partially inserted into the receiving tube 31 of the adjusting portion 30, and then the adjusting portion 30 is pushed toward the body 10 to engage with the body 10. That is, the protrusion 17 is inserted into the recess 37, such that the adjusting portion 30 is rotatably engaged with the body 10.

[0056] Subsequently, by rotating the adjusting part 30, the sliding member 40 moves forward until the fastening part 42 of the sliding member 40 protrudes to the upper part of the main body 10, and the cylindrical member 60 is connected to the fastening part 42. Then, by rotating the adjusting part in the opposite direction, the cylindrical member 60 retracts into the interior of the main body 10, and then the cap 20 is attached, thus completing the assembly.

[0057] Secondly Figure 7 a and Figure 7 b is a view illustrating the operation of a refillable solid applicator according to an embodiment, relating to the use of the applicator. Specifically, Figure 7 a is a cross-sectional view showing the cylindrical member 60 fully retracted into the body 10, and Figure 7 b is a cross-sectional view showing the state in which the cylindrical member 60 is advanced a predetermined length from the upper end of the main body 10 by rotating the adjusting part 30. When the adjusting part 30 is rotated, due to the relative movement of the threads 33 of the receiving tube 31 and the threads of the threaded portion 41 of the sliding member 40, the sliding member 40 moves toward the front portion of the main body 10, and the solid block 61 of the cylindrical member 60 protrudes from the main body 10.

[0058] In the configuration of the applicator disclosed herein, during the rotation of the adjusting portion 30, the planar portion 43 of the threaded portion 41 of the sliding member 40 engages with the region 51b of the inner surface of the guide ring 50, and thus the sliding member 40 only rises and falls without rotating, and thus the solid block 61 advances to the outside of the body 10 or retracts into the body 10 without rotating, making the solid block easy to use.

[0059] When the protrusion 46 is provided on the end of the threaded portion 41, even if the user further rotates the adjusting portion 30 after raising the sliding member 40 to its maximum value by rotating the adjusting portion 30, the protrusion 46 will be captured by the thread 33, and thus the sliding member 40 will no longer rise. That is, due to the presence of the grooves 35, 45, the diameter of the end of the threaded portion 41 can be reduced, while the diameter of the end of the receiving tube 31 can be increased within an allowable tolerance range. Therefore, the thread at the end of the threaded portion 41 and the thread 33 of the receiving tube 31 rotate around without wear, and at the same time, the protrusion 46 is captured by the thread 33 to prevent the sliding member 40 from rising and to prevent the sliding member 40 from being released from the adjusting portion 30.

[0060] Third, when replacing the cylindrical part 60, the cylindrical part 60 is moved forward by rotating the adjusting part 30 until the retainer 62 of the cylindrical part 60 is exposed outside the body 10. After this, the cylindrical part 60 is separated from the fastening part 42 by pulling the retainer 62, and the retainer 62 of the new cylindrical part 60 is inserted into the fastening part 42, so that the cylindrical part can be easily replaced.

[0061] Although this disclosure has been shown and described with reference to certain preferred embodiments thereof, those skilled in the art will understand that various variations in form and detail may be made in this disclosure without departing from the spirit and scope of the disclosure as defined by the appended claims. Therefore, the scope of this disclosure is not defined by the detailed description thereof but by the appended claims, and all differences within that scope shall be construed as included in this disclosure.
