Description

Technical Field

[0001] The present application relates to cosmetic application technology, and in particular to an applicator. Background Art

[0002] In the art, lip gloss and other cosmetics for lip application are usually applied by cotton tips. The cotton tips are made by firstly obtaining a plastic body by injection molding, then applying glue on the body, and finally using electrostatic flocking to allow the body after the glue is applied to absorb the fluff, thereby obtaining a cotton tip with a plastic body but a fluff layer on the surface.

[0003] However, the current cotton tips have the following disadvantages due to the use of glue: the glue is easy to debond, resulting in the risk of fluff falling off; there is a risk that the glue will dissolve in the cosmetic material. Once compatibility occurs, it will affect the quality of the cosmetics and the health of the user. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present application provides an applicator in which the mounting part, the application part and the fluff are integrally injection molded, omitting the traditional flocking process, so there is no risk of the fluff degumming and the glue dissolving in the cosmetic material.

[0005] The technical solution adopted by this application to solve its technical problems is:

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the embodiments of the present application. Obviously, the embodiments described in the present application are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the following drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0032] like Figure 1-9 As shown, an applicator is used to apply cosmetics, skin care products and / or medicines on hairless skin. The applicator includes a mounting portion 10 and an application portion 20 fixedly connected to the mounting portion 10. The application portion 20 is provided with at least two hairs 30. The mounting portion 10, the application portion 20 and the hairs 30 are an integral injection molding made of a thermoplastic material. The Shore hardness of the thermoplastic material is greater than 65A.

[0033] The applicator in the present application is an integral injection molded part made of thermoplastic material, that is, the mounting portion 10, the application portion 20 and the bristles 30 are integrally formed. Compared with the traditional brush head process, the present applicator omits the flocking process, thereby simplifying the production process of the applicator, improving production efficiency and reducing manufacturing costs; and the applicator does not need to be coated with glue, so there is no risk of the bristles degumming and the glue dissolving in the cosmetic material. The hardness of the thermoplastic material in the present application is controlled to be above 65 Shore A. Compared with traditional bristles, the hardness of the bristles in the present application is improved, so the ability to protect the gaps between the bristles is correspondingly improved, thereby improving the applicator's ability to carry materials at a time. The present application can be used for the application of skin care or makeup materials such as lip oil, lip gloss and lipstick.

[0034] Optionally, the Shore hardness of the thermoplastic material is 70A to 95A. Too much hardness of the fluff 30 affects the makeup effect, so the Shore hardness of the thermoplastic material in the present application is controlled between 70A and 95A, which not only greatly improves the ability of the applicator to carry material at a time, but also meets the makeup requirements of the fluff and improves the comfort of the user when applying makeup.

That is, the hair density in each area of ​​the application portion 20 is the same. The distance between two adjacent hairs 30 refers to the distance between the center points of the orthographic projections of the two adjacent hairs 30 on the surface of the application portion 20.

SKYPEL is a trade name registered by SK Chemicals for its engineering thermoplastic elastomers. It is an ester system thermoplastic elastomer (TPEE), which is similar to rubber in softness and elastic recovery, but is superior to rubber in mechanical strength, heat resistance and weather resistance. Without going through the vulcanization process, like ordinary thermoplastic resins, the copolymer amount of the soft segment is properly adjusted according to the usual polyester synthesis method with a resin that is easy to mold and process, thereby forming a soft and mechanical material suitable for various uses. TPEE is made by copolymerizing 1,4-butylene terephthalate and polybutanol. The increase in the proportion of hard segments can enhance physical rigidity and chemical stability, and the increase in the proportion of soft segments can improve flexibility and low-temperature performance.

[0058] G130D and G140D have similar flexibility, elasticity and mechanical strength to rubber, but its heat resistance and weather resistance are better than rubber. All grades of SKYPEL are block copolymers, consisting of hard (crystalline) segments of polybutylene-terephthalate and soft (non-crystalline) segments based on long-chain polyether glycol. Its properties are determined by the ratio of hard segments to soft segments.
