[0016] The technical aspects of the embodiments of the present invention will be clearly and completely described below in relation to the embodiments of the present invention. Obviously, the embodiments described in the present invention are only some embodiments of the present invention, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present invention.

[0017] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the drawings below are intended to distinguish between similar objects without necessarily being used to describe a particular order or priority. It should be understood that the objects so used may be interchanged where appropriate, such that the embodiments of the present invention described herein may, for example, be practiced in an order other than that shown or described herein. Furthermore, the terms "comprise" and "have" and all variations thereof are intended to cover a non-exclusive inclusion.

The device may be positioned in other different ways (rotated 90 degrees or at other orientations) and appropriately accounted for in the spatially relative descriptions used herein.

[0019] Example 1: As shown in Figures 1-2, the application assembly includes an applicator 110 and a mounting fixture 120. A first end of the applicator 110 is fixedly connected to the mounting fixture 120, and a second end of the applicator 110 is provided with a concave surface 111, which is recessed toward the first end of the applicator 110, and a flocked layer 112 is provided on the concave surface 111. A discharge hole 113 is provided in the applicator 110, and a discharge passage 121 is provided in the mounting fixture 120, and the discharge passage 121, the discharge hole 113, and the flocked layer 112 are in communication with each other. That is, the application material 500 permeates into the flocked layer 112 through the discharge passage 121 and the discharge hole 113.

[0020] In one possible embodiment, the component in the application assembly for directly contacting the keratinous layer of the user is a hair implant layer 112. The keratinous layer of the user may be skin or hair. Here, the skin of the user includes, but is not limited to, the surface skin of the face, neck, hands, feet, torso and extremities. The hair of the user may be hair or eyelashes. In a scene in which the application assembly is used, the hair implant layer 112 is used to apply the application material 500, which may be a cosmetic material or a skin care material. The application assembly is attached to a material dispenser having a material storage chamber.

[0021] In one possible embodiment, the application material dispenser may be a makeup brush or a makeup brush. The application material 500 in the material storage chamber flows into the flocked layer 112 through the discharge passage 121 and the discharge hole 113, and the user applies the application material 500 using the flocked layer 112. The application material 500 includes, but is not limited to, lip oil, lip gloss, lip balm, etc. The second end of the applicator 110 in this application is a free end, and the second end of the applicator 110 is provided with a concave surface 111, and the flocked layer 112 is planted on the surface of the concave surface 111, so that when applying makeup using the flocked layer 112, the concave arched flocked layer 112 can better fit the makeup area such as the lips, and the application effect of the material can be improved. When the material is a makeup material, this design can improve the fit of the makeup material and improve the makeup effect. When the material is a skin care product, this design can make the skin care product evenly cover the keratin layer of the user, thereby improving the care effect. The application material 500 penetrates directly into the flock layer 112 through the outlet holes 113, improving the efficiency of the makeup application.

[0022] As shown in Fig. 1, both ends of the discharge hole 113 are connected to the flocked layer 112 and the discharge passage 121, respectively. That is, as shown in Fig. 2, the discharge hole 113 penetrates the concave surface 111, making it easy for the application material 500 to flow directly into the flocked layer 112 through the discharge hole 113, further improving the efficiency of makeup application.

[0023] Optionally, the applicator 110 and the attachment 120 are one-piece two-color injection molded parts, where the applicator 110 is made of a first material and the attachment 120 is made of a second material, where the first material is different from the second material. Optionally, the hardness of the first material is less than the hardness of the second material. The applicator assembly 100 is one-piece two-color injection molded parts, where the two colors include a first material and a second material. The first material includes a thermoplastic material, an elastomeric material, a thermoplastic elastomer, a thermoplastic polyester elastomer, such as nitrile rubber, silicone rubber, ternary ethylene propylene rubber, styrene-ethylene-butene-styrene (SEBS), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), polyethylene (PE), polyethylene terephthalate, polypropylene (PP), thermoplastic elastomer (TPE), thermoplastic polyester elastomer (TPEE), and the like. The second material includes, but is not limited to, polypropylene, polycarbonate, polyethylene terephthalate-1,4-cyclohexanedimethanol, high density polyethylene, and the like.

[0024] During assembly, the applicator assembly 100 is fixedly attached to the base 210 via the attachment 120. The applicator 110 is made of a relatively soft material to ensure the makeup experience and makeup effect, and the attachment 120 is made of a relatively hard material to ensure the attachment strength between the attachment 120 and the base 210, preventing the applicator assembly 100 from falling off the base 210. In the prior art, the applicator assembly is usually injection molded from the same plastic, and if a relatively soft material is used for the applicator assembly, the connection between the applicator assembly and the base is not firm, and the applicator assembly is likely to fall off the base during use. If a hard material is used for the applicator assembly, the applicator assembly is hard, so the feel when it comes into contact with the application site is poor, and it is easy to rub the skin, causing damage to the user's skin. The applicator assembly 100 in the present application is made of a two-color injection molded product, which ensures a comfortable feel and makeup effect when the user applies makeup, and increases the attachment strength of the applicator assembly.

[0025] In one possible embodiment, the first material includes a thermoplastic elastomer and the second material includes polypropylene, i.e., the applicator 110 is made of a thermoplastic elastomer (TPE) and the attachment 120 is made of polypropylene (PP), or the applicator 110 is made of a soft polypropylene and the attachment 120 is made of a hard polypropylene, thereby satisfying the application assembly 100 having both flexibility and hardness at the same time.

[0026] 1, the outer wall of the fitting 120 extends radially outward to form a retaining ring 122 such that the retaining ring 122 abuts the pen body 410 when the application assembly is attached to the pen body 410.

[0027] 3, a coupling part 123 is fixedly provided in attachment 120, and coupling part 123 is fitted into applicator 110. There is a gap between attachment 120 and coupling part 123, and a first end of applicator 110 is fitted into this gap, and coupling part 123 is inserted into the inside of the first end of applicator 110, thereby increasing the bonding area between applicator 110 and attachment 120 and increasing the bonding strength therebetween.

[0028] Example 3: As shown in Figures 4 to 6, the pen head assembly includes an application assembly 100, a base 210, and a check valve 220. The attachment 120 is fixedly attached in the base 210, and the check valve 220 is attached in the base 210. The base 210 is provided with a first supply hole 211, and the check valve 220 controls the inflow of the application material 500 from the outside of the base 210 to the inside of the base 210 through the first supply hole 211. That is, the check valve 220 controls the flow of the application material 500 so that the application material 500 flows only from the outside of the base 210 to the inside of the base 210, and further permeates the bristles layer 112 through the discharge hole 113 of the application assembly 100. During use, the pen head assembly 200 is attached to the pen body 410, and the coating material 500 is placed in the pen body 410. The coating material 500 in the pen body 410 can enter the inside of the base 210 through the check valve 220 under the action of an external force, but the coating material 500 in the base 210 cannot return to the inside of the pen body 410 through the check valve 220, thereby protecting the coating material 500 in the pen body from contamination and extending the shelf life of the coating material 500.

[0029] As shown in FIG. 4 and FIG. 5, the check valve 220 is attached between the mounting fixture 120 and the base 210, and the seal portion 221 is fixed to the check valve 220, and the seal portion 221 can seal the first supply hole 211. In a natural state, the seal portion 221 blocks the first supply hole 211 and separates the inside and outside of the base 210. During use, the coating material in the pen body 410 is pushed open by an external force to cause the seal portion 221 to separate from the first supply hole 211, so that the coating material 500 enters the inside of the application assembly 100 through the first supply hole 211. The discharge passage 121 and the discharge hole 113 in FIG. 5 are filled with the coating material 500. The application assembly 100 in this embodiment uses the application assembly in the first embodiment. Optionally, the check valve 220 is made of a flexible material. It ensures that the sealing portion 220 can seal the first supply hole 211 while ensuring that the sealing portion 220 can deform away from the first supply hole 211 under the action of the coating material 500 .

[0030] 6, the fitting 120 is provided with a first protrusion 124 and the base 210 is provided with a second protrusion 212, with the first protrusion 124 being an interference fit with the second protrusion 212. The outer wall of the fitting 120 extends radially outward to form the first protrusion 124, and the inner wall of the base 210 extends radially inward to form the second protrusion 212. When the fitting 120 is placed on the base 210, the first protrusion 124 is an interference fit with the second protrusion 212, enhancing the bonding strength between the fitting 120 and the base 210.

[0031] 7, the pen head assembly 200 includes an application assembly 100, a base 210, and a check valve 220, and the application assembly 100 includes an applicator 110 and a mounting fixture 120. This embodiment differs from the embodiment 3 in that the application assembly of the embodiment 2 is used in this embodiment.

[0032] Example 5: As shown in FIG. 8, the coating material dispenser includes a pen head assembly 200, a pen cap assembly 300, and a pen body assembly 400, in which the pen head assembly 200 is fixedly mounted in the pen body assembly 400, and the pen cap assembly 300 is capped by the pen body assembly 400. This example adopts the pen head assembly 200 of Example 4, and the material discharge method of the pen body assembly 400 is not limited. Optionally, the material discharge method of the pen body assembly 400 includes manual or electric. Optionally, the material discharge method of the pen body assembly 400 includes tail button discharge, side button discharge, rotation discharge, or push discharge. The tail button discharge method means that a button is attached to the tail of the pen body, and the material in the pen body is pushed to the coating assembly by pressing the button on the tail. The side button discharge method means that a button is attached to the side of the pen body, and the material in the pen body is pushed to the coating assembly by pressing the button on the side. In the rotation ejection type, a rotating button is attached to the tail of the pen body, and the material in the pen body is pressed against the application assembly by rotating the rotating button. In the pressure ejection type, the pen body is made of a soft material, and the material in the pen body is pressed against the application assembly by directly pressing the pen body.

[0033] In one specific embodiment, the material discharge method of the pen body assembly 400 is a tail button discharge type. As shown in FIG. 8, the pen body assembly 400 includes a pen body 410, a piston 420, a nut 430, a screw 440, a spring 450, a ratchet tooth 460, a ratchet wheel 470, a ratchet seat 480, and a button 490. The pen body 400 accommodates an application material 500 inside. The pen head assembly 200 is fixedly mounted in the pen body 410, the nut 430 is mounted in the pen body 410, the screw 440 is mounted in the nut 430, and the screw 440 is screwed into the nut 430. The piston 420 is fixedly mounted on a first end of the screw 440, and the piston 420 is hermetically attached to the inner wall of the pen body 410. A second end of the screw 440 is fitted into the button 490, the ratchet teeth 460 are mounted within the ratchet seat 480, the ratchet wheel 470 and the ratchet teeth 460 are both fitted into the screw 440, the button 490 is fixedly fitted into the ratchet teeth 460, and the spring 450 is mounted between the ratchet wheel 470 and the nut 430.

[0034] Initially, the spring 450 is in a natural expanded state. When the user presses the button 490, the button 490 moves the ratchet teeth 460, which act on the ratchet wheel 470 to move the screw 440 and the piston 420. The piston 420 presses the coating material 500 in the pen body 410 toward the pen head assembly 200. The pressing force of the coating material 500 pushes open the sealing portion 221, i.e., moves the sealing portion 221 away from the first supply hole 211. The coating material 500 enters the discharge hole 113 through the first supply hole 211 and the discharge passage 121, and permeates the flocking layer 112 through the discharge hole 113, and is available for use by the user. At this time, the spring 450 is compressed. When the force applied to the button 490 is removed, the button 490 is reset by the restoring force of the spring 450.

[0035] It should be noted that those skilled in the art may make some modifications and improvements without departing from the concept of the invention, which are within the scope of protection of the invention, and therefore the scope of protection of the invention should be in accordance with the appended utility model claims.
