The pencil body (1) is provided with a tip (3), the cap (2) is provided with a clamping base (4), a movable piston (5) is arranged in the clamping base (4), and an elastic piece (6) is arranged between the clamping base (4) and the piston (5); a cavity (21) used for placing a material is formed between the end of the clamping base (4) close to the cap (2) and the inner wall of the cap (2), and compared with the pen body (1) for placing the material, the cap (2) has fewer limitations for placing the material; moreover, a through hole (51) is formed in the end of the piston (5) close to the cap (2), and the through hole (51) is communicated with the cavity (21); a placement slot (52) is formed in the piston (5) corresponding to the tip (3), and the placement slot (52) is communicated with the through hole (51); and the tip portion of the tip (3) is located in the through hole (51), and thus when the pencil body (1) is removed from the cap (2), the piston (5) moves outwards under the action of the elastic piece (6), so that two ends of the through hole (51) are blocked by the inner wall of the clamping base (4) and are not communicated with the cavity (21). Therefore, the material is not prone to plashing, and due to the certain size of the through hole (51), i.e., the space of a material taking bin, quantitative material taking can be achieved.

Description

A press-and-dip cosmetic pen Technical Field

[0001] The invention relates to the technical field of cosmetic pens, in particular to a press-and-dip cosmetic pen. Background Art

[0002] A cosmetic brush is a makeup tool used for applying makeup. Some types of brushes use liquid as the material. There are two main types of such brushes. One type has a liquid material filled into the pen body, and the material is drawn from the liquid sac through the pen tip. However, this type of container has certain limitations in terms of material filling. Since the sac is elongated, it is generally used with pearlescent materials of smaller particle size. The other type of brush has a filling bottle designed on the lid end, and a brush with a bristle or velvet tip on the pen body. The brush is inserted into the bottle to remove the material. However, this method of dipping the material can easily cause excessive dipping. This is because the amount of material is not fixed and is determined by feel. In addition, the brush head is usually placed to seal the filling bottle, so when the brush head is used, the material in the bottle is easily spilled due to external force.

[0003] Summary of the Invention

[0004] The object of the present invention is to provide a push-to-dip cosmetic pen. By placing the material body in the lid, certain limitations can be reduced. The arrangement of the piston and the elastic member can solve the problem of spillage. Moreover, since the size of the through hole, i.e., the material collection bin space, is fixed, quantitative material collection can be achieved.

[0005] The object of the present invention is achieved like this:

[0006] A press-and-dip cosmetic pen comprises a pen holder and a cover, wherein a pen tip is provided at one end of the pen holder close to the cover, a holder is provided at the opening of the cover, a movable piston is built into the holder, and an elastic member is provided between the holder and the piston;

[0019] Optionally, a vent hole connected to the outside world is provided at one end of the pen cap away from the pen shaft, and a second piston is also provided in the chamber, which divides the chamber into an upper chamber and a lower chamber. The lower chamber is connected to the outside world through the vent hole, and the upper chamber and the lower chamber are separated by the piston so that air cannot flow between the upper chamber and the lower chamber.

[0020] Optionally, steel balls for stirring the material evenly are provided in the upper chamber.

[0021] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0022] By placing the material in the cap, the present invention has fewer limitations than placing the material in the pen holder, allowing for the use of larger pearlescent particle sizes. Furthermore, by providing a piston and elastic member, when the cap is removed from the pen holder, the piston moves outward under the action of the elastic member, thereby blocking both ends of the through hole with the inner wall of the holder and preventing communication with the chamber. This means that the material is not easily spilled by external forces. Furthermore, since the size of the through hole, i.e., the space in the material collection bin, is fixed, quantitative material removal can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0035] As shown in Figures 1 to 6, a push-to-dip cosmetic pen includes a pen holder 1 and a cover 2. The pen holder 1 is provided with a pen tip 3 at one end near the cover 2. A holder 4 is provided at the opening of the cover 2. The holder 4 has a movable piston 5 built in, and an elastic member 6 is provided between the holder 4 and the piston 5.

[0036] Moreover, a chamber 21 for placing the material is formed between the end of the base 4 close to the cover 2 and the inner wall of the cover 2, and a through hole 51 is formed at the end of the piston 5 close to the cover 2, and the through hole 51 is connected to the chamber 21. At the same time, a placement groove 52 is formed on the piston 5 corresponding to the pen tip 3, and the placement groove 52 is connected to the through hole 51.

[0037] Therefore, during actual use, since the placement groove 52 is connected to the through hole 51, the material can be dipped. When the pen body 1 is removed from the cap 2, the piston 5 moves outward under the action of the elastic member 6, thereby blocking the ends of the through hole 51 by the inner wall of the holder 4 and preventing it from communicating with the chamber 21. Therefore, when the pen tip 3 is used to apply makeup, the material in the cap 2 will not be easily spilled due to external forces. Optionally, the tip of the pen tip 3 can be located in the through hole 51.

[0038] Therefore, the present invention places the material in the lid 2, which is less restrictive than placing the material in the pen holder, and can accommodate larger pearlescent particle sizes. This is because the pen tip 3 directly contacts the material, eliminating the need for material drainage through other media. Furthermore, through the arrangement of the piston 5 and the elastic member 6, when the pen holder 1 is removed from the lid 2, the piston 5 moves outward under the action of the elastic member 6, thereby blocking the ends of the through hole 51 with the inner wall of the holder 4 and preventing communication with the chamber 21. This means that the material is not easily spilled by external forces. Furthermore, since the size of the through hole 51, i.e., the material hopper space, is fixed, quantitative material removal can be achieved.

[0039] The shape and material of the pen tip are not fixed. It can be a foam pen tip, an injection-molded pen tip, or a pen tip of other adsorbable materials. At the same time, the shape can be round, square, polygonal, etc.

[0040] Moreover, the elastic member 6 can be a spring or an item made of other elastic materials. When a spring is selected, the specific structure is: first, the piston 5 is provided with a baffle 54 at one end close to the pen body 1, and the elastic member 6 is a spring, and the elastic member 6 is sleeved on the outside of the piston 5 and located between the base 4 and the baffle 54.

[0041] As shown in Figures 1 to 6, in one embodiment, a steel ball 7 is provided in the chamber 21 for stirring the material evenly. Therefore, when the material with pearlescent material is placed therein for a long time, the pearlescent material will settle and accumulate. At this time, the material can be stirred evenly by shaking the steel ball 7.

[0042] As shown in FIG3 , in one embodiment, when the pen body 1 is taken out, the tip of the pen head 3 will cause the material to splash out, so the placement groove 52 is sequentially provided with a plurality of ridges 53 along the direction toward the pen body 1, and the ridges 53 are used to prevent the material from splashing out when the pen body 1 is taken out.

[0043] It should be understood by those skilled in the art that, in addition to the ridges 53, other structures can be provided, such as a leak-proof design with multiple leaves, or by adding a sponge inside the piston 5. In addition, for use with relatively viscous materials, a pen tip can be designed to fit the inner wall without the need for leak-proof designs such as ridges, leaves, or sponges.

[0044] As shown in Figures 2, 3 and 5, in one embodiment, the connection between the cover 2 and the base 4 is that the cover 2 is firstly provided with a snap ring 8, and the snap ring 8 includes a connecting portion 1 81 and a connecting portion 2 82, wherein the connecting portion 1 81 is used to connect to the inner wall of the cover 2, and the connecting portion 2 82 is located above the connecting portion 1 81 and is used to connect to the inner wall of the base 4.

[0045] At the same time, a boss 22 is provided on the inner wall of the cover 2 , and the holder 4 abuts against the boss 22 .

[0046] Therefore, in actual use, the holder 4 is first abutted against the boss 22 to limit the initial position of the holder 4 , and the retaining ring 8 is provided to prevent the holder 4 from falling off the cover 2 .

[0047] Moreover, a groove 821 is formed on the outer side of the second connecting portion 82 , and a convex ring 41 matching the groove 821 is provided on the inner wall of the holder 4 . Secondly, a convex ring 811 is formed on the outer side of the first connecting portion 81 and is interference fit with the inner wall of the cover 2 .

[0048] As shown in FIG2 , FIG3 and FIG5 , in one embodiment, in order to achieve a better sealing effect, the piston 5 is provided with sealing rings 9 on both sides of the through hole 51 and at one end close to the pen body 1 to prevent the material from leaking from other places.

[0049] The installation structure of the sealing ring 9 is as follows: first, the piston 5 is provided with a groove 55 , and the sealing ring 9 is located in the groove 55 , or the sealing ring 9 is an insert and is injection molded together with the piston 5 .

[0050] As shown in Figures 2, 4 and 6, in one embodiment, the pen body 1 is provided with a mounting seat 10 at one end close to the cover 2, and the pen head 3 is provided on the mounting seat 10, and the inner wall of the cover 2 is connected to the outer side of the mounting seat 10.

[0051] The structure between the pen tip 3 and the mounting base 10 is as follows: the mounting base 10 is provided with a connecting groove 104 for placing the pen tip 3.

[0052] Moreover, the mounting seat 10 and the pen body 1 can be separate or integrated. When the two are separated, first, a groove four 101 and a convex ring five 102 are provided on the outer side of the mounting seat 10, and a convex ring four 11 and a groove five 12 are provided on the inner wall of the pen body 1, wherein the groove four 101 is adapted to the convex ring four 11, and the convex ring five 102 is adapted to the groove five 12.

[0053] At the same time, the connection between the cover 2 and the mounting seat 10 is that first, a plurality of protrusions 23 are provided on the inner wall of the cover 2, and a convex ring 103 is provided on the outer side of the mounting seat 10, and the convex ring 103 is adapted to the protrusions 23.

[0054] Furthermore, the mounting base 10 and the second connecting portion 82 also have some structural coordination. Specifically, the mounting base 10 has a second groove 105 on the outside, and the second connecting portion 82 has a second protruding ring 822 on the inner wall. The second protruding ring 822 is located within the second groove 105. A flexible material, such as an elastic resin, can be provided within the groove 105. The elastic resin can be integrally injection molded, or a sealing ring or other structure can be provided within the groove. Alternatively, an interference fit between the mounting base 10 and the inner wall of the connecting portion can be formed to create an airtight seal.

[0055] Another embodiment of the present invention will now be described with reference to FIG7 . FIG7 is a schematic cross-sectional view of a push-and-dip cosmetic brush according to one embodiment of the present invention. As shown in FIG7 , the main difference between the push-and-dip cosmetic brush of this example and the embodiment shown in FIG1-6 is that the inner wall of the placement groove 52 of the piston 5 is no longer provided with ridges, and the pen tip 3 is provided with a soft brush hair structure. Optionally, a groove is no longer provided on the outer wall of the piston 5 to accommodate the sealing ring. Instead, an external piston rib 56 is provided on the outer wall of the piston 5 near the lid, and a sealing effect is achieved by an interference fit between the external piston rib 56 and the inner wall of the holder 4. In addition, the sealing effect can also be achieved by using a two-color injection molding method for the piston 5.

[0056] Figure 8 is a cross-sectional schematic diagram of a press-and-dip cosmetic brush according to another embodiment of the present invention. The difference between this embodiment and the embodiment shown in Figure 7 is that the mounting base 10 of this embodiment is provided with a mounting base through hole 13 in the vertical direction, the pen tip 3 is provided with a soft brush hair structure and is connected to a plug 31 at the rear end, and the plug 31 is connected to the pen tip 3 as a whole and is arranged in the mounting base through hole 13 of the mounting base 10.

[0057] FIG9 is a schematic cross-sectional view of a push-to-dip cosmetic brush according to another embodiment of the present invention. FIG9 differs from the aforementioned embodiment primarily in that the push-to-dip cosmetic brush of this embodiment no longer has a retaining ring. Instead, a retaining rib 42 is provided directly on the outer wall of retaining base 4. This retaining rib 42 forms an interference fit with the inner wall of lid 2, thereby sealing the chamber and allowing retaining base 4 to be fixedly mounted within lid 2. Furthermore, an internal piston rib 57 may be provided within piston 5, which forms an interference fit with the inner wall of the mounting base to seal the chamber.

[0058] Figure 10 is a schematic cross-sectional view of a push-to-dip cosmetic brush according to another embodiment of the present invention. The main difference between Figure 10 and the aforementioned embodiment lies in the improved pen cap of this embodiment. Specifically, as shown in Figure 10 , the end of the pen cap 2 (the bottom end of the pen cap shown in Figure 10 ) away from the pen shaft 1 is provided with a vent 24 that communicates with the outside world. A second piston 25 is also located within the chamber 21. The second piston 25 divides the chamber into an upper chamber 251 and a lower chamber 252. The lower chamber 252 communicates with the outside world through the vent 24. The upper and lower chambers 251 and 252 are separated by the second piston 25, preventing air from flowing between them. A steel ball 7 is located within the upper chamber 251. When the pen tip 3 is removed from the cap 2, the volume of the upper chamber 251 increases, the pressure decreases, and the second piston 25 moves upward under the influence of atmospheric pressure, thereby maintaining a constant pressure within the upper chamber 251.

[0059] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. At the same time, the present invention is not limited to the above embodiments. Therefore, the present invention is subject to various changes and improvements without departing from the principles and scope of the present invention. Such changes and improvements fall within the scope of the invention as claimed.
