Methods of implementation
[0032] As illustrated in Figures 1-8, a cosmetic application head comprises a mounting part 10 and an application part 20 fixed together, the application part 20 being a cylindrical structure, the surface of the application part 20 having a flocking layer 21, the fineness of the fibers of the flocking layer 21 being 2.4D to 3.6D, the length of the fibers being 1.2mm to 1.8mm, the application head being manufactured from thermoplastic elastomer materials by one-piece injection molding. In manufacturing, after forming the application head from thermoplastic elastomer materials by an injection mold, a flocking layer 21 is formed on the surface of the application part 20 by a flocking process.When in use, the application head is assembled on the brush handle by the mounting part 10, the application part 20 using the flocking layer 21 to dip into the makeup material and apply the makeup to the user's makeup area, completing the makeup operation.
[0033] Fiber fineness is from 2.4D to 3.6D, where D represents denier, a fixed-length density unit for silk, synthetic fibers, and nylon textile fibers, indicating the weight in grams of a 9000m-long fiber at a standard moisture content, the unit being denier. Denier is a unit of measurement for fiber fineness, a 9000m-long fiber weighing 600 grams is called a 600D fiber. A 9000m-long yarn weighing 600 grams is called a 600D yarn. The higher the number, the thicker the yarn or fiber.
[0034] In the present invention, the application head is made from thermoplastic elastomer materials, the application part is designed as a cylindrical structure, and the fineness of the fibers is 2.4D to 3.6D, the length of the fibers is 1.2mm to 1.8mm, so the application head obtained when applying makeup allows the material to be applied more uniformly and delicately, thereby improving the effect of makeup.
[0035] The fineness of the fibers is from 2.7D to 3.3D. Optionally, the fineness of the fibers may be 2.4D, 2.6D, 2.8D, 3D or 3.2D. Optionally, the fineness of the fibers may be 3.0D. The fiber length is 1.35mm to 1.65mm. Optionally, the fiber length can be 1.3mm, 1.5mm, 1.6mm or 1.7mm. Optionally, the fiber length can be 1.5mm. In an exemplary embodiment, the fiber fineness is 3.0D and the length is 1.5mm, which provides an application part that applies the material most evenly, providing the best makeup effect and strong loading capacity.
[0036] The thermoplastic elastomer materials include at least one of polyurethane, styrene, and polyester thermoplastic elastomer materials. Optionally, the applicator may be made from polyester (TPEE) thermoplastic elastomer materials, polyurethane (TPU) thermoplastic elastomer materials, or styrene (TPES) thermoplastic elastomer materials.
[0037] The application head is manufactured from polyester-type thermoplastic elastomer materials by one-piece injection molding. Polyester-type TPEE, also called polyester rubber, is a type of linear block copolymer containing hard segments of PBT (polybutylene terephthalate) and soft segments of polyol or polyether, offering good elasticity, excellent flexural strength, wear resistance and a wide operating temperature range, and having good resistance properties to chemicals, oil, solvents and atmospheric aging.
[0038] The density of the polyester type thermoplastic elastomer materials is from 0.95g / cm3 to 1.45g / cm3, the Shore hardness of the polyester type thermoplastic elastomer materials is from 45D to 68D. Optionally, the density of the polyester type thermoplastic elastomer materials may be from 1.2g / cm3, the Shore hardness may be from 56D. Optionally, the specifications of the polyester type thermoplastic elastomer materials may be those of DuPont Hytrel 5553FG.
[0039] As shown in Figures 2-8, the first end of the application part 20 is fixed to the mounting part 10, the second end of the application part 20 is free, and the second end of the application part 20 has a groove 22, using the groove to take an appropriate amount of material during a single dipping, improving the loading capacity of the application head, reducing the number of dippings. The second end of the application part 20 forms a tip, the tip can be used to draw fine lines, thereby improving the effect of makeup and expanding the functionality of the application head.
[0040] As illustrated in Figures 2-8, the application portion 20 comprises a main portion and a top, the first end of the main portion being attached to the mounting portion 10, the second end of the main portion being attached to the top, the main portion comprising a cylindrical structure, the top comprising at least one of a truncated cone-shaped structure, a conical structure, and a spherical structure. The spherical structure may be a full spherical structure or a partial spherical structure. In this exemplary embodiment, the application portion 20 is divided into two parts, one part being the main part and the other the apex, the main part having a cylindrical structure and being attached to the mounting portion 10. Optionally, the mounting portion 10 may also have a cylindrical structure, the mounting portion 10 being arranged coaxially with the application portion 20. Optionally, the apex is attached to the main part and the apex has a hemispherical structure. The use of an application portion combining cylindrical and spherical structures improves the uniformity of material application by the application head, and the loading capacity at each dipping is strong.
[0041] As illustrated in Figures 2-3, the application portion 20 has a beveled surface 23, the beveled surface 23 being located at the apex, or the beveled surface 23 extending from the apex to the main portion, the angle formed between the beveled surface and the central axis of the application portion 20 being an acute angle. That is, the application portion 20 is cut along the beveled surface 23 to remove a part of the structure, thereby forming a tip at the end of the application portion 20, the tip being usable for drawing fine lines, thereby improving the effect of makeup and expanding the functionality of the application head. Optionally, as illustrated in [Fig.l], the length of the projection of the center line of the beveled surface 23 onto the center axis of the application portion 20 is Ll, the length of the application portion 20 is L2, the ratio L1 / L2 being 32% to 48%.Optionally, L1 / L2 can be 38% to 42%.
[0042] As illustrated in Figures 2-3, the beveled surface 23 is oriented toward the inside of the application part 20 to form a groove 22, the surface of the groove 22 having a flocking layer 21. That is, the application part 20 has a spoon-like structure, the groove at the top being able to take an appropriate amount of material in a single dipping, improving the loading capacity of the application head, reducing the number of dippings, and thus improving the makeup efficiency.
