Description

Technical Field

[0001] This application relates to the technology of cosmetic packaging materials, specifically to artificial leather decorative members, their manufacturing methods, and cosmetic containers.

Background Art

[0002] Cosmetics are already widely used as daily consumables. With the development of society and the ever-improving aesthetic awareness of humanity, the pursuit of fashionability and novelty has become an eternal topic for people. The requirements for people's cosmetic containers have also changed from the conventional economic practicality to high-class fashionability. Therefore, in order to meet this need of consumers, usually, a patch of artificial leather is joined to the cosmetic container. However, the current artificial leather patch is pressed from multilayer materials, so it not only has a high cost but is also disadvantageous for mass production. Moreover, it is easy to cause peeling between the multilayer materials, which affects the visual effect.

It should be understood that objects used in this manner are interchangeable where appropriate, so that the embodiments of this application described herein may be carried out, for example, in an order other than those illustrated or described herein. Moreover, the terms "includes" and "has," and all their variations, are intended to conceal non-exclusive inclusion. For example, a process, method, system, product, or apparatus including a series of steps or units may include steps or units not explicitly listed, or other steps or units specific to those processes, methods, products, or apparatus.

It should be understood that spatial relative terms are intended to allow for different orientations in use or operation other than the orientation described in the diagram. For example, if the device in the drawing is upside down, a device described as "above another device or structure" or "above another device or structure" may later be positioned as "below another device or structure" or "below another device or structure." Therefore, the exemplary term "above" may include two orientations: "above" and "below." The device may also be positioned in other different ways (90-degree rotation or other orientations), and the spatial relative descriptions used here should be appropriately explained.

[0038] An artificial leather decorative component, wherein the artificial leather decorative component is provided on the surface of a cosmetic container, and the raw material components of the artificial leather decorative component include a thermoplastic polyurethane elastomer.

[0039] The artificial leather decorative component may be selected to contain, as a raw material, 84 to 99.5 parts by weight of thermoplastic polyurethane elastomer, 0.05 to 0.5 parts by weight of antioxidant, and 0.05 to 0.5 parts by weight of lubricant.

Hindered phenols include antioxidants 1010, 1024, 1076, 1135, 1098, and 245; phosphite esters include antioxidants 168, P-EPQ, PEP-36, 626, 9228, and DPDP; thioethers include antioxidants DSTP, DLTP, and DMTP; and triazines include antioxidants STA-1, 565, and 3114.

[0044] The Shore hardness of the thermoplastic polyurethane elastomer is 63-69A. Selectively, the Shore hardness of the thermoplastic polyurethane elastomer is 65-69A. Selectively, the Shore hardness of the thermoplastic polyurethane elastomer is 68A. The thermoplastic polyurethane elastomer has a 100% modulus of elasticity of 2 MPa or higher and a 300% modulus of elasticity of 4 MPa or higher. The elongation at break of the thermoplastic polyurethane elastomer is 400% or higher. The tensile strength of the thermoplastic polyurethane elastomer is 10 MPa or higher. The density of the thermoplastic polyurethane elastomer is 1.0-1.4 g / cm³. 3 The tear strength of thermoplastic polyurethane elastomer is 40 kN / m or more.

[0045] The glass transition temperature of thermoplastic polyurethane elastomers is -45°C to -40°C. The glass transition temperature (Tg) is measured using differential scanning calorimetry under conditions of 10°C / min. Selectively, the properties of thermoplastic polyurethane elastomers are as follows: 100% modulus of elasticity is 2-5 MPa, 300% modulus of elasticity is 4-8 MPa, elongation at break is 600-800%, and density is 1.1-1.25 g / cm³. 3 It has a tensile strength of 10-20 MPa and a tear strength of 60-70 kN / m.

[0046] The raw material components further include 0.3 to 10 parts by weight of a color masterbatch. The raw materials for the color masterbatch include polyurethane elastomer, polyolefin, pigment, filler, dispersant, etc. The pigment includes inorganic pigments or organic pigments.

A color masterbatch obtained using titanium white powder as a pigment is a white color masterbatch, and a color masterbatch obtained using carbon black as a pigment is a black color masterbatch. By adding a color masterbatch, it is possible not only to obtain decorative components of different colors, but also to improve the toughness of the decorative components.

[0047] The raw material components further include 1 to 15 parts by weight of polyolefin. Polyolefin is added to the raw material as a toughness reinforcing agent, and because the decorative material containing polyolefin has good toughness, the resulting decorative material has a pleasant feel and is not sticky.

Here, polypropylene is PP, polyethylene is PE, polyolefin elastomer is POE, ethylene-ethylene acetate copolymer is EVA, and methyl methacrylate is MMA.

[0053] The raw material components further include 5 parts by weight of polyolefin elastomer and 5 parts by weight of polyethylene.

[0054] As shown in Figure 4, the cosmetic container includes an artificial leather decorative member, the artificial leather decorative member being joined to a mounting surface of the cosmetic container 200, the mounting surface including a flat or curved surface. The mounting surface includes the top surface and / or the surrounding side surfaces. That is, the decorative member is joined to the top surface of the cosmetic container, or to the surrounding side surfaces of the cosmetic container, or to both the top surface and the surrounding side surfaces of the cosmetic container. Here, the top surface of the cosmetic container is a flat or curved surface, and the surrounding side walls of the cosmetic container are curved surfaces. In other words, the decorative member is joined to a mounting surface such as a flat or curved surface of the cosmetic container 200.

[0055] The decorative component is attached to the mounting surface of the cosmetic container 200 by adhesive, engagement, or heat pressure. This decorative component has an appearance and feel similar to leather and, because it is attached to the surface of the cosmetic container, not only protects the container but also provides a leathery visual appearance, enhancing the product's quality.

[0056] As shown in Figures 1-3, the decorative member includes a decorative member body 100, the decorative member body 100 includes a decorative portion 113, the decorative portion 113 includes at least one of a projection, a groove, and a suture. The decorative portion 113 and the decorative member body 100 are integrally molded by injection molding. The artificial leather decorative member includes a decorative member body 100. The decorative member body 100 includes a first surface 110 and a second surface 120 that are positioned opposite each other. The first surface 110 includes a raised portion 111 and a recessed portion 112 that are spaced apart from each other. The recessed portion 112 is a projection on the second surface 120 which is a joint. The joint is used to join the decorative member body 100 to the cosmetic container 200. Here, the first surface 110 of the decorative member body 100 is the outer surface, the second surface 120 is the inner surface, and the joint is a part of the second surface 120. Optionally, a planar joint is directly attached to the outer surface of the cosmetic container via adhesive or tape, and the first surface 110 serves to protect and decorate the container, with the first surface 110 being the decorative outer surface. The shape of the decorative member body 100 can be adjusted according to the structure of the cosmetic container, for example, it can be rectangular, square, oval, circular, etc. In addition to the decorative member body, the decorative member may further include other components. For example, a protective film may be attached to the first surface 110 of the decorative member body 100 to protect the batch substrate, and an adhesive layer may be attached to the second surface 120 to attach the batch substrate to the surface of the cosmetic container. This decorative member has an appearance and feel similar to leather and, because it is attached to the surface of the cosmetic container, it not only serves to protect the container but also gives a leathery visual appearance and improves the grade of the product. This decorative member is made of plastic material and is more wear-resistant and elastic than leather. Compared to conventional products where artificial leather is bonded to a silicon substrate obtained by pressing, this decorative component has higher hardness, greater toughness, and greater durability.

[0057] A decorative portion 113 is provided on the first surface 110, and the decorative portion 113 is either recessed toward the second surface 120 side or protrudes onto a raised portion 111. The decorative portion 113 shown in Figure 4 is A. In practical applications, the letter A can be created from any image. The decorative portion 113 may be any uppercase or lowercase letter of the alphabet, a number, a Chinese character, or other special symbol. The symbol can be formed directly during the molding process of the decorative member, making it easy and convenient to create. The decorative portion of the decorative member can be selected by the consumer as their favorite decorative part, or a character with a specific meaning, thus meeting the diverse needs of consumers. In another possible embodiment, a corresponding insert can be inserted or attached to the groove formed by the decorative portion 113. In another embodiment, the decorative portion 113 can also be designed as a projection. The decorative portion 113 protrudes onto the raised portion 111, i.e., the decorative portion is higher than the first surface 110. Consumers can touch the symbol, and the overall structure of the decorative member is more three-dimensional and more novel.

[0058] There is a cavity between the decorative member body 100 and the mounting surface of the cosmetic container 200. The presence of this cavity allows the portion of the decorative member containing the cavity to deform when pressed, improving the tactile feel. While conventional leather materials can deform under pressure due to the inherent tension of the material itself, the artificial leather decorative member of this invention, through the action of the cavity, can achieve the same pressure deformation effect and tactile feel as genuine leather. Without the cavity, the material would be hard under pressure, resulting in a low degree of deformation and poor tactile feel, thus placing high demands on the material of the decorative member.

[0059] The cavity does not need to be filled with any material. Optionally, the cavity may contain a flexible filler. The filler may include flexible materials such as sponge, foamed cotton, cotton, or silica gel.

[0060] The decorative portion 113 divides the cavity into M sub-cavities, and the lower surface of the decorative portion 113 is joined to the mounting surface of the cosmetic container 200. Here, M ≥ 2 and M is an integer. That is, the lower surface of the decorative portion 113 protrudes toward the cosmetic container, and the lower surface of the decorative portion 113 is joined to the mounting surface of the cosmetic container 200, dividing the cavity into two, three, or three or more sub-cavities.

[0061] The decorative member body 100 in the area corresponding to the cavity has a protruding arc structure. If two arbitrary points are taken on the decorative member body 100 in the area corresponding to the cavity, and the thicknesses of the decorative member body 100 at these two points are D1 and D2, then the difference between D1 and D2 is smaller than the tolerance of the decorative member body. The decorative member body 100 in the area corresponding to the cavity has a convex arc structure of the same thickness.

[0062] A method for manufacturing artificial leather decorative components is provided, comprising the following steps. Manufacturing of thermoplastic polyurethane elastomer particles: After uniformly mixing raw materials containing polyol, isocyanate, and chain extender, the mixture is injected into a twin-screw extruder and granulated to obtain thermoplastic polyurethane elastomer particles. Injection molding of artificial leather decorative components: Thermoplastic polyurethane elastomer particles, antioxidants, and lubricants are injected into an injection molding machine, and the artificial leather decorative components are obtained by injection molding using the injection molding machine.

[0063] Here, the manufacturing process for thermoplastic polyurethane elastomer particles includes the following steps. Preparation of raw materials: Weigh out the raw materials containing polyols, isocyanates, and chain extenders according to the required amounts. Degassing: The raw materials are degassed in a vacuum environment. Mixing: The raw materials are placed in a high-speed mixer and uniformly stirred, and the resulting mixture is then dried. Granulation: The dried mixture is added through the main feed hopper of a twin-screw extruder, and thermoplastic polyurethane elastomer particles are obtained through plasticization, extrusion, tension, air drying, and granulation.

[0064] Here, the injection molding process for the artificial leather decorative component is characterized by including the following steps. Material composition: Weigh out materials containing thermoplastic polyurethane elastomer particles, antioxidants, and lubricants according to the required proportions. Injection into injection molding machine: The thermoplastic polyurethane elastomer particles are injected into an injection molding machine and heated and melted. Addition of auxiliary agents: After adding an antioxidant to the injection molding machine and mixing it uniformly, a lubricant is added to the injection molding machine and mixed uniformly to obtain a molten mixture. Molding: The molten mixture is injected into a mold of an injection molding machine and injection molded to obtain an artificial leather decorative component.

[0065] This invention first degasses raw materials such as polyols, isocyanates, and chain extenders, then mixes and dries them before granulating them in a twin-screw extruder to obtain thermoplastic polyurethane elastomer particles. The hardness, elasticity, and elongation of the plastic polyurethane elastomer obtained using a specific raw material blending ratio can meet the demand for artificial leather decorative components. Finally, the thermoplastic polyurethane elastomer particles obtained by injection molding, along with chemical additives such as antioxidants and lubricants, are injection molded in an injection molding machine to obtain an integrally molded artificial leather decorative component. As a result, the production cost of the decorative component is low, which is advantageous for large-scale industrial production, and it also has good wear resistance, making wear less noticeable and allowing the product's aesthetic appearance to be maintained for a long time.

[0066] Here, the material further comprises at least one of polyolefin, color masterbatch, and anti-tack agent. In the injection step into the injection molding machine, at least one of the polyolefin, color masterbatch, and anti-tack agent is placed in the injection molding machine and heat-melted together with the thermoplastic polyurethane elastomer particles. During injection molding, the color masterbatch and at least one of the polyolefin are added to the injection molding machine and injected together with the thermoplastic polyurethane elastomer particles to obtain a leather decorative member, thereby increasing the toughness of the leather decorative member. As a result, the leather decorative member has a more comfortable feel and is not sticky. During injection molding, to obtain leather decorative members of different colors, only polyolefin or color masterbatch may be added, or polyolefin and color masterbatch may be added simultaneously.

[0067] In the degassing step, the degassing time is 10-30 minutes, and in the mixing step, the drying conditions for the mixture are a temperature of 80-95°C and a time of 3-4 hours.

Degassing: The raw materials are degassed under vacuum conditions. The degassing time is 15 minutes. Mixing: The raw materials are placed in a high-speed mixer and uniformly stirred, and the resulting mixture is then dried. The drying conditions are: temperature 90°C, time 3.5 hours. Granulation: The dried mixture is added through the main feed hopper of a twin-screw extruder, and thermoplastic polyurethane elastomer particles are obtained through plasticization, extrusion, tension, air drying, and granulation.
