Description

Technical Field

[0001] The present invention relates to an automatic opening and closing makeup brush, and more particularly, to an automatic opening and closing makeup brush, in which an opening and closing top end of an opening and closing body that is raised and lowered according to the operation of an operating body can not only automatically open and close the entrance of a first shell where a main brush emerges, but also has simple components and easy assembly, so it has high productivity, thereby ensuring stable lifting and lowering of the opening and closing body, and can realize the production of various designed products according to the selection of an outer packaging shell. At the same time, in addition to the upper main brush, a lower auxiliary brush can also be used to form a hybrid automatic opening and closing makeup brush. Background Art

[0002] Various cosmetic tools with opening and closing inlets have been disclosed in the past. For example, a portable cosmetic brush in Utility Model Registration No. 20-0072709 (June 2, 1993) describes a brush that can be easily adjusted in length and opened and closed by a guide tube having multi-stage locking grooves.

[0003] The gazette of the registered utility model records as follows: the brush cover is opened to expose the brush, and when the cover is closed, the sliding tube combined with the lower shell body can be raised, and after the brush is folded, the cover is closed. Specifically, a locking rod is protruded from the lower part of the inner circumferential surface of the sliding tube, and the guide tube arranged at the end of the brush forms a guide channel with a multi-stage locking groove for use by the locking rod. A coil spring is inserted into the outer circumferential surface of the guide tube. When the spring elastically supports the locking rod, the sliding tube is rotated so that the sliding tube rises with the aid of the elasticity of the spring, thereby the exposure degree of the brush can be adjusted according to the position where the locking rod is stuck on the multi-stage locking groove.

[0004] However, the registered utility model is implemented in a form that allows the brush to be exposed at multiple levels, with the purpose of adjusting the degree of exposure of the brush according to needs. However, in actual makeup methods, the thickness and shape (flat or cylindrical, etc.) of the brush used are different depending on the makeup area. Considering the actual situation, the practicality will be reduced. In comparison, it is a removal structure suitable for lipstick rather than makeup brushes.

[0005] In addition, a brush is proposed in the cosmetic brush assembly of Utility Model Registration No. 20-0319261 (2003.06.27), which has the following shape: similar to the method commonly used in ordinary writing tools (specifically ballpoint pens), the brush is exposed when the pressing head is pressed once, and the brush is retracted when it is pressed again.

[0006] However, this registered utility model does not solve the problem of foreign matter flowing into the exposed hole while the brush is being carried, causing the brush to be contaminated. If a cover is used separately, when the pressing head is accidentally pressed, the collision between the brush and the cover may cause the makeup brush to break or be damaged.

[0007] A brush is proposed in the makeup brush mechanism of Patent Registration No. 10-0456267 (2004.10.29). In the brush containing powdered cosmetics, when a protective cap is pulled out from the exposed portion of an intermediate shell partially embedded in an external shell, a compression protrusion formed in the center of the protective cap can cause a brush support body that is telescopically folded in multiple stages inside the intermediate shell to unfold and expose the brush at the same time.

[0008] However, the registered patent cannot solve the problem that when closing the protective cap, special attention needs to be paid to ensure that the pressing protrusion is accurately engaged with the locking part located between the cosmetic brush.

[0009] At the same time, in the multi-purpose shell of patent registration No. 10-0393302 (2003.07.21), there is no need to cover the cover, so that the opening and closing body moves forward in the brush body and covers the brush; the multi-purpose shell of the registered patent also includes an upper shell, a middle shell, a lower shell, a core, a core rod, a moving rod, a clip, a cap, and an opening and closing component; observing the combination structure of the opening and closing component, a pair of opening and closing components are inserted between the middle shell and the fixed liner (packing), and the protrusion formed at the lower end of the opening and closing component is fixed to the cap rod (cap The cover body is a semicircular cover body in the opening and closing component, and is made of an elastic material so that when the cap and the lower shell are pushed downward to take out the cosmetics, they are separated according to the thickness of the core body. On the contrary, when the cap and the lower shell are pushed upward to retract the writing tool, the opening and closing component approaches the upper shell and makes the cover bodies contact each other, thereby preventing the problems of the prior art, that is, preventing foreign matter from flowing in and unintentional damage, and realizing automatic opening and closing without a cover.

[0010] In addition, a male threaded portion is formed on the outer surface so as to be fastened with the female threaded portion of the upper shell, a circular fixing groove is formed laterally along the inner circumference on the inner side thereof, and a longitudinal plug-in groove is formed on the fixing liner so as to allow the opening and closing component to be inserted, and the fixing liner is formed with a longitudinal guide groove in a long form. In addition, a longitudinal sliding groove is formed, a male threaded portion is formed on the outer side of the lower end portion thereof, and a plug-in groove is formed on the inner side portion thereof so as to allow the opening and closing component to be fixed to the cap rod formed with the spiral groove.

[0011] In this registered patent case, the backward linear motion of the lower shell is followed by the linear motion of the cover rod, thereby causing the idle motion of the moving rod, followed by the forward linear motion of the core rod, and finally returning to the forward linear motion of the core body.

[0012] However, in the registered patent, due to the spiral rotation movement part of the moving rod combined with the cap rod and the up-and-down movement spiral part of the core rod combined with the spiral groove of the moving rod, the shell is extended further according to the length of the male thread forming part, so the shell cannot be shortened, thereby reducing the convenience of carrying. Therefore, the existing automatic opening and closing makeup brush has a lot of room for improvement in terms of assembly, operation performance and durability. Summary of the invention

[0013] [Technical issues to be solved]

[0014] Therefore, the purpose of the present invention is to provide an automatic opening and closing type makeup brush, in which the opening and closing top end of the opening and closing body that is raised and lowered according to the operation of the operating body can not only automatically open and close the entrance of the first shell where the main brush emerges, but also has simple components and easy assembly, so it has high productivity, thereby ensuring the stable lifting and lowering of the opening and closing body.

[0015] In addition, the purpose of the present invention is to provide an automatic opening and closing type makeup brush, so that the second guide part of the opening and closing body is placed on the first guide part on both sides of the guide body, so as to move stably, and the guide body accommodates a lifting body including a main brush, and in order to correspond to the upper large opening and closing top and the middle small connecting rod of the opening and closing body, the first guide part is composed of an upper wide-width 1-1 guide member and a lower narrow-width 1-2 guide member, thereby realizing stable lifting of the lifting body and opening and closing of the first shell entrance of the opening and closing body.

[0016] Furthermore, the object of the present invention is to provide an automatic opening and closing makeup brush, so that the connecting rod of the opening and closing body is fixed by a belt combined with the annular groove of the guide body, thereby improving the assembly performance and ensuring the lifting and lowering stability of the opening and closing body.

[0017] Furthermore, an object of the present invention is to provide an automatic opening and closing type makeup brush, wherein a stop portion that is stuck in a stop sill when the opening and closing body descends is formed on the connecting rod, thereby ensuring stable opening and closing body lifting and lowering operation and opening and closing accuracy, and the stop sill is between the upper and lower 1-1 and 1-2 guide members of the first guide portion of the guide body.

[0018] Furthermore, an object of the present invention is to provide an automatic opening and closing type makeup brush, in which the second locking piece or the stopper of the opening and closing body combined with the first locking piece of the operating body, or both of them, have an outwardly protruding spacer, so that when the opening and closing body is raised or lowered, the tolerance between the upper first shell or the lower second shell and the opening and closing body is minimized, and stable and gentle lifting of the opening and closing body is ensured, and other parts other than the spacer can save materials and enhance unit price competitiveness by maximizing slimming.

[0062] When describing the automatic opening and closing type makeup brush A according to the present invention, for convenience, refer to FIGS. 1 and 2. Figure 2 , based on the loose general direction,

[0063] The main brush B1 side of the lifting body 10 is defined as the upper part, the opposite side thereof is defined as the lower part, and the first guide parts 25 facing the two sides of the guide body are defined as the left and right. Unless otherwise specified, the detailed description and claims of the invention related to other drawings are also directed and described according to this standard.

[0064] Below, as a representative embodiment, with Figure 1 and Figure 2 The makeup brush A will be described below.

[0065] The automatic opening and closing cosmetic brush A according to the present invention comprises a lifting body 10, a guide body 20, an operating body 30, an opening and closing body 40, a first shell C1 and a second shell C2.

[0066] They are partially or entirely made of synthetic resin, and as required, part of the housing and other parts may be made of aluminum or its alloys, or other alloys. The main brush B1 and the auxiliary brush B2 may be made of synthetic resin or natural materials.

[0067] In Figure 1 and Figure 2 The first embodiment shown, and Figures 3 to 5 In the drawings and accompanying photographs of the second to fourth embodiments shown, the process of assembling the components from left to right and downward in stages is shown.

[0068] The direction of the visible surface of each component can be changed and displayed as needed to better describe the characteristics.

[0069] The lifting body 10 includes: a lower male thread portion, specifically a first male thread portion b1 , a first non-circular portion 13 in the middle and outer portion, and an upper main brush B1 .

[0070] Specifically, the first male threaded portion b1 at the lower end constitutes a convex male threaded portion and corresponds to a portion of the lifting stroke, and the corresponding female threaded portion of the operating body 30, specifically the first female threaded portion n1, has a section length corresponding to the lifting stroke of the lifting body;

[0071] The upper portion of the connection platform 111 having the male screw portion b1 at the lower end is provided with a base 13a, and the main brush B1 is connected to the base.

[0072] Preferably, the main brush B1 or the brush described below Figure 5 The hair collecting body of the auxiliary brush B2 shown is made of metal, specifically, an aluminum tube Al, in order to ensure productivity and hair collecting stability.

[0073] Preferably, the first non-circular portion 13 of the lifting body for linear lifting is ensured by the linkage between the male threaded portion of the lifting body 10 and the female threaded portion of the operating body 30, through the convex non-circular portion at the lower end of the base, the elliptical non-circular base 13a or the elliptical non-circular aluminum tube Al, or all of them.

[0074] In the accompanying drawings, the convex non-circular portion at the lower end of the base mainly serves as the first non-circular portion.

[0075] Next, the guide body 20 includes: a receiving portion 21 in which the lifting body 10 is built; a second non-circular portion 23 for internal guidance, which corresponds to the first non-circular portion 13; and two groove-shaped first guide portions 25, which are arranged opposite to each other on both sides of the outside.

[0076] The first non-circular portion 13 and the second non-circular portion 23 can be realized in various ways such as the usual D-shaped cutting, U-shaped cutting, key and keyway forms, and the drawings show that the second non-circular portion 23 is a guide rail type on both sides combined with the raised first non-circular portion 13 on both sides.

[0077] Each first guide part 25 includes: a 1-1 guide member 25a with a wide upper width, a 1-2 guide member 25b with a narrow lower width, and a stopper 25c located between the two guide members; the opening and closing top 41 of the opening and closing body 40 corresponds to the 1-1 guide member 25a, and the connecting rod 41l corresponds to the 1-2 guide member 25b.

[0078] In the accompanying drawings, the 1-1 guide member 25a is planar, and the 1-2 guide member 25b is a slit or a notch groove (or can be a simple groove-like structure). As needed, part or all of the 1-1 guide member and the 1-2 guide member can have a groove-like structure, a slit or a notch groove structure; the groove-shaped first guide portion 25 is a general term for them.

[0079] The second guide portion placed in the groove-shaped first guide portion 25 refers to: a flat plate portion on the inside or inner surface corresponding to the opening and closing top end 41, the connecting rod 41l, and the stopper st of the opening and closing body 40.

[0080] Therefore, the first guide parts 25 on both sides of the guide body 20 are respectively placed with the second guide parts of the opening and closing body 40 and move stably. In order to correspond to the upper large opening and closing top 41 and the middle small connecting rod 41l of the opening and closing body 40, the first guide part is composed of the upper wide 1-1 guide member 25a and the lower narrow 1-2 guide member 25b, so that the stable lifting and lowering of the lifting body 10 and the opening and closing of the first shell C1 entrance C1a of the opening and closing body 40 can be realized. The guide body 20 accommodates the lifting body 10 including the main brush B1.

[0081] In addition, the guide body 20 has an annular groove 25d overlapping with the 1st-2nd guide member 25b. When the connecting rod 41l is installed on the 1st-2nd guide member, the annular groove 25d is combined with a belt b, thereby preventing the connecting rod 41l of the opening and closing body 40 from detaching.

[0082] Preferably, the belt b is elastic for easy assembly and has a certain degree of lubricity in terms of material properties.

[0083] Thus, the opening and closing body connecting rod 411 is fixed by the belt connected to the annular groove 25d of the guide body 20, thereby improving the assembly performance and ensuring the lifting and lowering stability of the opening and closing body.

[0084] The operating body 30 includes: a female thread portion, specifically a first female thread portion n1, which is combined with the male thread portion of the lifting body 10, specifically the first male thread portion b1; the operating body 30 also includes a first locking member 33 disposed outside.

[0085] The female thread portion of the operating body 30 is linked with the external male thread portion of the lifting body 10; more specifically, the male thread portion of the lifting body 10 is the first male thread portion b1.

[0086] The operating body 30 is composed of a first tube 1p and a second tube 2p, and the first tube is inserted into the second tube.

[0087] A first female threaded portion n1 is formed inside the first pipe 1p and is coupled to the first male threaded portion b1.

[0088] A second male thread portion b2 is formed at the lower end of the first pipe 1p, and a second female thread portion n2 coupled to the second male thread portion b2 is formed inside the second pipe 2p.

[0089] Furthermore, a pair of opening and closing bodies 40 on which the two first guide parts 25 of the guide body 20 are placed are observed, which include: a large opening and closing top 41 at the top, a small connecting rod 41l in the middle, and a second locking piece 43 at the bottom, the second locking piece 43 is combined with the first locking piece 33 of the operating body 30, and the second guide part is placed at the first guide part 25 of the guide body 20.

[0090] The following describes the large, medium and small sizes of the interconnected opening and closing top 41, the second locking piece 43 and the connecting rod 41l, as well as the corresponding wide, medium and narrow sizes of the 1-1 guide piece 25a, the first locking piece 33 and the 1-2 guide piece 25b of the first guide portion 25 of the guide body 20; among them, it is both a comparison of relative sizes and a selection of size differences to achieve specific functions.

[0091] Specifically, in the opening and closing body 40, the large opening and closing top 41 and the small connecting rod 41l are selected to reduce weight, save materials, ensure lightness, and ensure smooth lifting and lowering.

[0092] The medium-sized second locking piece 43 located at the bottom is placed on the corresponding groove-shaped middle-width first locking piece 33, and the upper end of the groove-shaped first locking piece 33 constitutes a reducing portion 33a of the amplitude corresponding to the small connecting rod 41l, thereby preventing the second locking piece 43 combined with the first locking piece from detaching upward.

[0093] In addition, the connecting rod 411 of the opening and closing body 40 is provided with a medium-sized stopper st which is caught in the stopper 25c of the guide body 20 so as to limit the descending degree of the opening and closing body 40 when the entrance of the first shell C1 is locked.

[0094] Thus, a stopper st that is stuck in the stopper 25c when the opening and closing body descends is formed on the connecting rod, thereby ensuring stable lifting and lowering operation of the opening and closing body and opening and closing accuracy. The stopper 25c is between the 1-1 guide member and the 1-2 guide member of the first guide part of the guide body.

[0095] The first housing C1 accommodates a first assembly A1 composed of a lifting body 10, a guide body 20 and an opening and closing body 40, and has an inlet C1a which is opened and closed by an opening and closing top end 41 of the opening and closing body 40 to allow the main brush B1 of the lifting body 10 to enter and exit.

[0096] The two opening and closing top ends 41 are shaped like human lips. Figure 3 In the second embodiment shown, the shape of the part marked with number 41a on the lower right side of the assembled makeup brush A can enhance the aesthetic sense of the design; as needed, it can also be formed in various images or trademarks, and the image, etc. can be formed in three dimensions or planes, so as to get rid of the monotony or become a highlight that attracts the eye. When the inlet C1a of the first shell is closed, the end of the opening and closing top 41 is slightly protruding lip shape 41a, thereby enhancing the visibility.

[0097] As shown in Figure 1 and Figure 2 As shown, in order to ensure the ease of assemblage and productivity, the first shell C1 is composed of a 1-1 shell 1c and a 1-2 shell 2c which are plugged together in the upper and lower parts. In addition, for the same reason, the outer shell of the second tube 2p constituting the operating body 30, that is, the second shell C2 is also composed of a 2-2 shell c2 and a 2-1 shell c1 which are plugged together in the upper and lower parts.

[0098] As shown in Figure 1 and Figure 2 As shown in the makeup brush A, the 1-1 shell 1c, the 1-2 shell 2c, the 2-1 shell c1 and the 2-2 shell c2 are all made of synthetic resin, or as needed, some shells, such as the 1-2 shell 2c or the 2-1 shell c1, or both, can be made of metal, specifically aluminum.

[0099] like Figure 3 In the makeup brush A of the second embodiment shown, the first shell C1 is a metal single tube made of a single aluminum or its alloy, and the second shell C2 is composed of the 2-1 shell c1 and the 2-2 shell c2, both of which are metal tubes made of aluminum or its alloy, and the 2-2 shell c2 is formed with a coupling hole h3 for coupling with the gem a.

[0100] like Figure 4In the makeup brush A of the third embodiment shown, the first shell C1 is composed of a 1-1 shell 1c and a 1-2 shell 2c, and are made of synthetic resin and metal respectively. The second shell C2 is a single tube made of synthetic resin, and a stop cap s3 is additionally combined with the end of the second tube 2p of the operating body 30, so that the inner end of the second shell C2 is just combined with the stop cap s3, thereby ensuring the firmness of the combined state.

[0101] like Figure 5 In the makeup brush A of the fourth embodiment shown, the first shell C1 is composed of a 1-1 shell 1c and a 1-2 shell 2c, and are made of synthetic resin and metal respectively. The second shell C2 is a single tube made of synthetic resin, or an auxiliary brush B2 is arranged at the end, specifically a hair collecting structure on the aluminum tube Al, and the auxiliary brush is protected by a brush cap.

[0102] As required, the auxiliary brush is shown in FIG. 1 and FIG. 2 of the registration bulletin of the utility model registration No. 200478988 of the applicant of the present invention on December 1, 2015 [Dual brush assembly]. Figure 2 In the embodiment, the auxiliary brush can be transformed into the following form: before the cover body 25 covers the hair collecting body 23, the protective cover 27 is covered to collect and protect the hair collecting body which is larger than the cover body.

[0103] In addition, in Figure 3 The single first shell C1 shown or Figure 2 , Figure 4 and Figure 5 In the binary 1-2 shell 2c shown, a male first fastening portion h1 is provided at the upper part of the annular groove 25d at the two lower narrow 1-2 guide members 25b in the first guide portion 25 of the guide body 20 and at a position 90 degrees offset therefrom in a cross-arranged structure. Correspondingly, a female second fastening portion h2 is formed on the first shell at a position opposite to the male first fastening portion h1. Therefore, when the first assembly A1 is assembled with the first shell C1, the male first fastening portion h1 of the guide body 20 and the female second fastening portion h2 of the first shell are combined without the use of adhesives, etc., so that a physically firm combination can be achieved.

[0104] Considering the situation of assembling the first shell C1 downward from the top to the bottom of the guide body 20, preferably, the male first fastening part h1 is a raised structure with a lower top and a higher bottom. Specifically, as shown in the figure, the male first fastening part h1 and the female second fastening part h2 are a circular protrusion and a circular hole, respectively.

[0105] Further, preferably, the second locking member 43 or the stopper st of the opening and closing body 40, or both, are formed with outwardly protruding spacers s1, s2.

[0106] By means of the spacers s1 and s2, when the opening and closing body 40 is raised or lowered, the tolerance between the upper first shell C1 or the lower second shell C2 and the opening and closing body 40 is minimized, and stable and gentle raising and lowering of the opening and closing body can be ensured. Other parts except the spacers can save materials and enhance unit price competitiveness by maximizing slimming.

[0107] In addition, as shown in Figure 1 and Figure 2 In the first embodiment shown, two friction protrusions P facing each other are formed on the 2-1 shell c1. The two friction protrusions protrude outward more than the outer peripheral surface of the 2-1 shell c1, and the elastic force is increased by the 11-shaped cut holes H located on both sides of the friction protrusions.

[0108] Since the tolerance between the friction protrusion P and the second shell C2, specifically the 2-2 shell c2, is reduced, the elasticity and unique lubrication properties of the O-ring can be utilized to ensure easy assembly, stable assembly state, and smooth lifting and lowering operations of the opening and closing body 40 and the lifting body 10.

[0109] Based on this, Figure 5 In the operating body 30 of the fourth embodiment shown, the second tube 2p forms an O-shaped groove rg at the lower part of the first locking piece 33, and the O-ring ro is set in the O-shaped groove, thereby reducing the tolerance between the second tube 2p and the second shell C2, and utilizing the elasticity and unique lubrication properties of the O-ring to ensure easy assembly, stable assembly state, and smooth lifting and lowering operations of the opening and closing body 40 and the lifting body 10.

[0110] As needed, refer to Figure 5 The contact part of the shell C composed of the first shell C1 and the second shell C2 and the components built therein (the part not related to the spiral movement and lifting movement of the operating body 30, the opening and closing body 40 and the lifting body 10) can be fixed by an adhesive, or fixed internally using a tape or film with exactly minimized tolerance, or fixed by minimizing the tolerance of the contact part itself.

[0111] Figure 1 and Figure 2 As a reference, the operating state of the automatic opening and closing type makeup brush A is described.

[0112] When one hand holds the 2-2 shell c2 and the other hand holds the lower end of the 2-1 shell c1 and pulls it downward, due to the locking action between the first locking piece 33 and the second locking piece 43, while the operating body 30 descends, the opening and closing body 40 steadily descends under the action of the first guide part 25, the second guide part and the belt b; finally, the two opening and closing tops 41 located in the lower wide space inside the 1-1 shell unfold based on their own elasticity and contact with the 1-1 guide part 25a, thus opening the entrance C1a of the 1-1 shell 1c which is narrow at the top and wide at the bottom.

[0113] Specifically, the second tube 2p combined with the 2-2 shell c2 has a second female threaded portion n2 on its inner circumference, which rotates relative to the second male threaded portion b2 at the lower end of the first tube 1p; at this time, the first tube 1p with the first female threaded portion n1 in the operating body 30 rotates in place due to the upper annular protrusion r2 for combination, and the upper annular protrusion r2 for combination is engaged with the inner annular groove r1 on the inner circumference of the 1-2 guide 25b of the guide body 20; through the rotation of the first tube 1p, the first male threaded portion b1 and the first female threaded portion n1 are linked together, so that the lifting body 10 rises, and the main brush B1 is exposed to the outside from the open entrance C1a of the 1-1 shell 1c.

[0114] The lifting body 10 performs a linear lifting motion under the restraint of the first non-circular portion 13 and the second non-circular portion 23 of the operating body 30 .

[0115] If one hand holds the 2-2 shell c2 again, and the other hand holds the lower end of the 2-1 shell c1 and pushes upward, the operating body 30 rises and the opening and closing body 40 rises accordingly; finally, the inner sides of the ends of the two opening and closing top ends 41 located in the upper narrow space inside the 1-1 shell contact the two closed entrances to close the entrance C1a of the 1-1 shell 1c which is narrow at the top and wide at the bottom.

[0116] Specifically, the second tube 2p combined with the 2-2 shell c2 has a second female threaded portion n2 on its inner circumferential surface rotated relative to the second male threaded portion b2 at the lower end of the first tube 1p; at this time, the first tube 1p with the first female threaded portion n1 in the operating body 30 rotates in place due to the annular protrusion r2 engaged with the inner annular groove r1 of the guide body 20; through the rotation of the first tube 1p, the first male threaded portion b1 is linked with the first female threaded portion n1, so that the lifting body 10 descends, and the main brush B1 descends from the entrance C1a of the self-sealed 1-1 shell 1c and is in a built-in state.

[0117] In the above description, the description of the commonly known technologies related to the makeup brushes is omitted, but those skilled in the art can easily speculate, infer and reproduce it.

[0118] In addition, in the above description of the present invention, the makeup brush with a specific shape and structure is mainly described with reference to the accompanying drawings, but it should be interpreted that technicians in this field can make various modifications, changes and substitutions, and such modifications, changes and substitutions belong to the scope of protection of the present invention.
