Patent Application
20250120494
This application is based upon and claims priority to Chinese Patent Application No. 202311337964.0, filed on Oct. 16, 2023, the entire contents of which are incorporated herein by reference.
The present application relates to makeup tool technology, and in particular to a cosmetic applicator head.
For existing cosmetic brushes such as an eyelash brush, an eyebrow brush, and a lip gloss pen, a surface of a brush head is usually flocked to form a cotton head. The cotton head is used to dip a cosmetic material for makeup. However, the existing cotton head has non-uniform application to affect a makeup effect.
The present application provides a cosmetic applicator head to overcome the above defect. The applicator head is made of a thermoplastic elastomer, and the application portion is a columnar structure. Therefore, the applicator head applies a material more uniformly and exquisitely to achieve a better makeup effect.
To solve the technical problems, the present application employs the following technical solutions:
A cosmetic applicator head includes a mounting portion and an application portion that are fixedly connected, where the application portion is a columnar structure; a flocked layer is provided on a surface of the application portion; a flock in the flocked layer has a fineness of 2.4 D to 3.6 D, and a length of 1.2 mm to 1.8 mm; and the applicator head is an integrally injection-molded piece made of a thermoplastic elastomer.
Optionally, the flock has the fineness of 2.7 D to 3.3 D.
Optionally, the flock has the fineness of 3.0 D.
Optionally, the flock has the length of 1.35 mm to 1.65 mm.
Optionally, the flock has the length of 1.5 mm.
Optionally, the thermoplastic elastomer includes at least one of a thermoplastic polyurethane elastomer (TPU), a styrenic thermoplastic elastomer (TPES) and a thermoplastic polyester elastomer (TPEE).
Optionally, the applicator head is the integrally injection-molded piece made of a TPEE.
Optionally, the TPEE has a density of 0.95 g/cm3 to 1.45 g/cm3, and a Shore hardness of 45 D to 68 D.
Optionally, the application portion includes a first end fixedly connected to the mounting portion, and a second end being a free end; and the second end of the application portion is provided with a groove.
Optionally, the second end of the application portion forms a tip.
Optionally, the application portion includes a main body portion and a top portion; the main body portion includes a first end fixedly connected to the mounting portion, and a second end fixedly connected to the top portion; the main body portion includes a cylindrical structure; and the top portion includes at least one of a truncated cone-shaped structure, a conical structure and a spherical structure.
The present application has the following beneficial effects:
In the figures: 10—mounting portion, 20—application portion, 21—flocked layer, 22—groove, and 23—machined oblique plane.
The following describes the technical solutions in the embodiments of the present application clearly and completely with reference to the embodiments of the present application. Apparently, the embodiments described are merely some rather than all of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
It should be noted that the terms “first”, “second” and so on in the description and claims of the present application and in the above accompanying drawings are intended to distinguish similar objects but do not necessarily indicate a specific order or sequence. It should be understood that the objects used in such a way may be exchanged under proper conditions to make it possible to implement the described implementations of the present application in sequences except those illustrated or described herein. Moreover, the terms “include”, “have” and their variants mean to cover a non-exclusive inclusion. For example, a process, method, system, product or device that includes a list of steps or units is not necessarily limited to those steps or units which are clearly listed. Instead, they may include other steps or units which are not expressly listed or inherent to such a process, method, product, or device.
For ease of description, spatially relative terms, such as “above”, “on the upper side of”, “on the upper surface of” and “on”, can be used to describe the spatial positional relationship between components or features shown in the figure. It should be understood that the spatially relative terms are intended to encompass different orientations of the components in use or operation in addition to those shown in the figure. For example, if a component in the figure is inverted, it is described as a component “above other component or structure” or “on other component or structure”. Therefore, the component will be positioned as “below other component or structure” or “under other component or structure”. Therefore, the exemplary term “above” may include both orientations “above” and “below”. The component may also be positioned in other different ways (rotated by 90 degrees or in other orientations), but the relative description of the space should be explained accordingly.
Embodiment: As shown in
For the expression that the flock has the fineness of 2.4 D to 3.6 D, D is the abbreviation of Denier. The Denier is a fixed-length measurement unit for a density of fine silks, artificial fibers and nylon textile fibers, and refers to a mass in grams of a 9,000-meter-long fiber at a given moisture regain. The Denier is a unit of measure for the fineness of the fiber. If the 9,000-m-long fiber has a weight of 600 g, the fiber is called a 600-D fiber. If the 9,000-m-long yarn has a weight of 600 g, the yarn is called a 600-D yarn. The bigger the number, the thicker the yarn or the fiber.
In the present application, the applicator head is made of the thermoplastic elastomer, and the application portion is the columnar structure. The flock has the fineness of 2.4 D to 3.6 D, and the length of 1.2 mm to 1.8 mm. Therefore, in makeup, the applicator head applies the material more uniformly and exquisitely to achieve a better makeup effect.
The flock has the fineness of 2.7 D to 3.3 D. Optionally, the flock has the fineness of 2.4 D, 2.6 D, 2.8 D, 3 D or 3.2 D. Optionally, the flock has the fineness of 3.0 D. The flock has the length of 1.35 mm to 1.65 mm. Optionally, the flock has the length of 1.3 mm, 1.5 mm, 1.6 mm or 1.7 mm. Optionally, the flock has the length of 1.5 mm. In an embodiment, the flock has the fineness of 3.0 D, and the length of 1.5 mm. In this way, the application portion has the most uniform material application, the best makeup effect, and the strong carrying capacity.
The thermoplastic elastomer includes at least one of a TPU, a TPES and a TPEE. Optionally, an applicator is made of the TPEE, the TPU or the TPES.
The applicator head is the integrally injection-molded piece made of a TPEE. The TPEE, also known as polyester rubber, is a type of linear block copolymer containing a polybutylene terephthalate (PBT) polyester hard segment and an aliphatic polyester or polyether soft segment. It exhibits good elasticity, excellent ductility, wear resistance, a wide temperature range, and desirable resistance to chemical media, oil, solvent and atmospheric aging, etc.
The TPEE has a density of 0.95 g/cm3 to 1.45 g/cm3, and a Shore hardness of 45 D to 68 D. Optionally, the TPEE has the density of 1.2 g/cm3, and the Shore hardness of 56 D. Optionally, the TPEE has a specification of Hytrel 5553FG of the DuPont.
