[0020] The technical aspects of the embodiments of the present application will be described clearly and completely below in relation to the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by a person skilled in the art without performing creative labors belong to the protection scope of the present application.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the drawings below are intended to distinguish between similar objects without necessarily being used to describe a particular order or sequence. It should be understood that the data used in this manner can be interchanged where appropriate, such that the embodiments of this application described herein can be practiced, for example, 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. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units explicitly listed, but may include steps or units not explicitly listed or other steps or units inherent to the process, method, product, or apparatus.

[0022] As shown in Figs. 1 to 14, the patch for a cosmetic container includes a patch base 10 made of a plastic material that is integrally injection molded. The patch base 10 includes a first surface 20 and a second surface 30 that are provided opposite to each other. The first surface 20 includes alternatingly arranged protuberances 21 and recesses 22. The recesses 22 are projected onto the second surface 30 as a coupling portion. The coupling portion is used to couple the patch to the cosmetic container. The first surface 20 of the patch base 10 is an outer surface, the second surface 30 is an inner surface, and the coupling portion is a part of the second surface 30. Optionally, the coupling portion is a flat surface. The coupling portion is directly attached to the outer surface of the cosmetic container through an adhesive or adhesive tape, and the first surface 20 realizes the role of protecting and decorating the container. The first surface 20 is a decorative outer surface. The shape of the patch base 10 can be adjusted according to the structure of the cosmetic container, for example, a rectangle, a square, an oval, a circle, etc. The patch may include components other than the patch base 10. For example, a protective film for protecting the patch substrate 10 may be attached to the first surface 20 of the patch substrate 10, and an adhesive layer for attaching the patch substrate to the surface of the cosmetic container may be attached to the second surface 30. The patch has an appearance and feel similar to leather and is attached to the outer surface of the cosmetic container, not only protecting the container but also giving people the visual feeling of leather, improving the grade of the product. The patch is made of plastic material and is more wear-resistant and elastic than leather. Compared with the conventional product in which the surface of the artificial leather is bonded to the silica gel substrate by pressing, the patch has higher hardness, stronger toughness, and more durability.

[0023] As shown in Figs. 1-2, adjacent ridges 21 and recesses 22 are connected, and the innermost part of the recesses 22 is a connecting bar 23. In a possible embodiment, the first surface 20 is provided with ridges 21 and recesses 22, and the ridges 21 and recesses 22 are arranged in a continuous alternating pattern, and the innermost part of the recesses 22, i.e., the lowest point of the recesses shown in Fig. 4, is provided with a connecting bar 23. The connecting bar 23 separates the first surface 20 into a plurality of parallel ridges 21. Although four ridges 21 are shown in Fig. 1, they can be installed arbitrarily as required. Alternatively, three to eight ridges 21 are provided, and the lengths of each ridge may be the same or different, and similarly the widths may be the same or different. Alternatively, the upper surface of the raised portion 21 is an arcuate surface protruding away from the second surface, and the upper surface of the recessed portion 22 is an arcuate surface recessed toward the second surface, and the recessed portion 22 is used to connect the two raised portions 21 to make a gradual transition between the raised portions and form a smooth surface. At the innermost portion of the recessed portion 22, a connecting bar 23 is formed to imitate the effect of the leather being divided in the middle by a stitching.

[0024] Optionally, the combination of the ridges 21 and the recesses 22 has a linear structure, a V-shaped structure, a W-shaped structure, a zigzag structure or a wave-shaped structure. In practical applications, the shape of the ridges 21 and the recesses 22 can be determined according to the specific shape of the patch. For example, referring to FIG. 1, if the structure of the patch is square, the ridges 21 and the recesses 22 can be designed as linear, wave-shaped, etc. structures. If the structure of the patch is circular, the ridges 21 and the recesses 22 can be designed as V-shaped, W-shaped, etc. structures. Of course, to ensure the coordination of the patch, the connecting bar structure of the recesses 22 is also adjusted accordingly. Optionally, the ridges 21, the recesses 22 and the connecting bar 23 have the same shape. The ridges 21 and the recesses 22 can be arranged along the longitudinal direction, the transverse direction or the diagonal direction of the patch base. The raised portion 21 and the recessed portion 22 shown in FIG. 1 are arranged straight along the longitudinal direction of the patch base 10, but the raised portion 21 and the recessed portion 22 can also be rotated 45° clockwise or counterclockwise and arranged along the diagonal direction of the patch base 10, and of course they can be rotated at any angle between 0 and 90°, or the raised portion 21 and the recessed portion 22 can be rotated 90° and arranged along the width direction of the patch base 10.

[0025] The protuberances 21 and the recesses 22 are both arranged along the longitudinal direction of the patch substrate 10, and both the protuberances 21 and the recesses 22 penetrate the entire or part of the longitudinal direction of the patch substrate 10. For convenience of explanation, the X-axis direction in FIG. 1 is defined as the longitudinal direction of the patch substrate 10, and the Y-axis direction is defined as the width direction of the patch substrate 10. As shown in FIG. 1, the protuberances 21 and the recesses 22 are both arranged along the longitudinal direction of the patch substrate 10, and are arranged over the entire longitudinal direction. That is, the protuberances 21 and the recesses 22 are arranged in sequence and repeatedly along the width direction of the patch substrate 10, and both have the same length. FIG. 4 shows a left side view of the patch. As can be seen from the figure, the first surface 20 resembles a wave-like structure, with the upwardly protruding portions being the protuberances 21 and the downwardly recessed portions being the recesses 22. Of course, the protuberances 21 and the recesses 22 may be arranged in a part of the longitudinal direction of the patch substrate. Optionally, the length of the raised portion 21 (or the recessed portion 22) occupies more than half the total length of the patch body.

[0026] As shown in Figures 1-2, a connecting bar 23 is provided around the peripheral edge of the first surface 20. The connecting bar 23 is provided around the periphery of the first surface, which can improve the durability of the product. The peripheral connecting bar is consistent with the recessed connecting bar, which is more beautiful and closer to the appearance of the leather product.

[0027] Example 1: As shown in Figures 1-4, the upper surface of the tie bar 23 is a smooth and flat plane, and the upper surfaces of the tie bar 23 in the recess 22 and the tie bar 23 around the first surface are all smooth and flat. The patch mold for producing this structure is simpler and has a low processing cost. Or, the upper surface of the tie bar 23 includes a plurality of spaced apart protrusions. The tie bar 23 is a micro-protrusion array. Example 3: As shown in Figures 9-12, the tie bar 23 in the recess and the tie bar 23 around the first surface both include spaced apart protrusions to imitate the sewing thread structure in leather. The protrusions penetrate the entire surface of the tie bar 23. The patch using this structure has a better leather imitation effect. The first surface 20 in Example 3 is also provided with the alphabet A, and this feature will be described in detail below.

[0028] Alternatively, the second surface 30 is entirely flat, or the joint is flat, and the other areas of the second surface 30 except the joint are concave. In a possible embodiment, the entire second surface is flat. Therefore, the entire second surface is adhered to the cosmetic container, and the adhesion strength between the patch and the cosmetic container is high, and the patch is not likely to fall off. In another possible embodiment, only the joint is flat, and the other areas of the second surface are concave, that is, the thickness of each part of the raised portion 21 is uniform and consistent. A patch having such a structure is easy to be injection molded and easy to be industrially produced.

[0029] Example 2: As shown in Figures 5 to 8, the first surface 20 is provided with a symbol 24. The symbol 24 is recessed toward the second surface 30 side, or the symbol 24 protrudes to the protuberance 21. The recession of the symbol 24 toward the second surface 30 side, that is, forms a continuous groove on the first surface 20. The continuous groove forms the symbol 24 having a certain meaning. The symbol may be any figure. Optionally, the symbol 24 is an alphabet, a number, a Chinese character, or other special symbol. The symbol 24 is integrally injection molded with the patch base 10. Optionally, the symbol 24 may be a single symbol, or a combination in which multiple symbols are configured together. The symbol 24 shown in Figure 5 is A. In practical application, the alphabet A can be created in any image. The symbol 24 is any uppercase or lowercase alphabet, a number, a Chinese character, or other special symbol. The symbol is directly formed during the molding process of the patch base 10, and can be created easily and conveniently. The symbols on the patch can be selected by consumers' favorite designs, and can also be selected with characters having specific meanings, so as to meet the diverse needs of consumers. In another possible embodiment, the grooves formed by the symbols 24 can be fitted with or pasted with corresponding fitting members. In other embodiments, the symbols 24 can be designed to be protruding. The symbols 24 protrude into the protuberances 21, that is, the symbols are higher than the first surface 20. The consumers can touch the symbols, and the structure of the whole patch is more three-dimensional and more novel.

[0030] When the symbol 24 is recessed toward the second surface 30, the deepest part of the recess 22 is in the same horizontal plane as the upper surface of the symbol 24, creating a texture and enhancing the similarity of the imitation of leather. The upper surface of the symbol 24 is a smooth, flat plane.

[0031] Example 4: As shown in Figs. 13-14, the first surface 20 has a leather pattern. Optionally, the entire first surface 20 is covered with a dense leather pattern. In the manufacturing process, the first surface can have a leather pattern by patterning the mold. Patterning methods include laser patterning and chemical etching patterning. Different patterning patterns can be designed as needed to obtain the required leather pattern.

[0032] The patch substrate 10 is a patch substrate made of a TPU material, a patch substrate made of a PP material, a patch substrate made of a PVC material, or a patch substrate made of a PET material, where TPU (ThermoPlastic polyUrethane) is thermoplastic polyurethane elastomer rubber, PET (PolyEthylene Terephthalate) is polyethylene terephthalate, PP (PolyPropylene) is polypropylene, and PVC (PolyVinyl Chloride) is polyvinyl chloride.

[0033] Alternatively, the patch base 10 is a patch base made of a TPU material, and the properties of the TPU material are density: 1.0 to 1.3 g / cm 3 , Shore hardness: 60~75A, Tensile strength: 10~20MPa, 100% modulus: 1.5~2.5MPa, 300% modulus: 4~6MPa, Breaking elongation: 600~800%, Tear strength: 60~70KN / m, Abrasion resistance: 85~95mm 3 , glass transition temperature: -45 to -40°C. The inspection standards for each index of the TPU material are as follows: density adopts the ASTM D792 standard; Shore hardness adopts the ASTM D2240 standard; tensile strength, 100% modulus, 300% modulus and tear strength adopt the ASTM D412 standard; tear strength adopts the ASTM D624 standard; abrasion resistance adopts the DIN53516 standard. The glass transition temperature Tg is measured by differential scanning calorimetry, with the condition being 10°C / min. Using the TPU material with the above characteristics is a guarantee for manufacturing a patch with a skin feel. In one embodiment, the performance of the TPU material is as follows. As physical properties, density: 1.18g / cm3 , Shore hardness: 66A. Mechanical properties: tensile strength: 17MPa, 100% modulus: 2MPa, 300% modulus: 5MPa, breaking elongation: 750%, tear strength: 65KN / m, abrasion resistance: 90mm 3 Thermal properties include glass transition temperature: -42°C.

[0034] The mold is used to manufacture the above-mentioned patch for cosmetic container. The patch is injection molded once. That is, the patch base 10 and the features such as the raised portion 21, the recessed portion 22, the connecting bar, the protrusions on the connecting bar, the symbols, the leather pattern, etc. on the patch base are injection molded once. Therefore, the manufacturing process is simple. Here, the features such as the connecting bar, the protrusions on the connecting bar, the symbols, the leather pattern, etc. are not limited to the above four embodiments, but can be arbitrarily combined in specific embodiments.

[0035] It should be pointed out to those skilled in the art that any modifications or improvements made without departing from the concept of the present application will fall within the scope of protection of the present application, and therefore the scope of protection of the present application should be in accordance with the scope of the attached utility model claims.
