[0037] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of this 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 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 variations thereof 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 clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0039] As shown in Figures 1-14, a patch for a cosmetic container includes a patch base 10 made of an integrally injection-molded plastic material. Patch base 10 includes a first surface 20 and a second surface 30 disposed opposite each other. First surface 20 includes a raised portion 21 and a recessed portion 22 spaced apart from each other. The projection of recessed portion 22 on second surface 30 forms a joint, which is used to connect the patch to the cosmetic container. First surface 20 of patch base 10 is the exterior surface, while second surface 30 is the interior surface. The joint is a portion of second surface 30. Optionally, the joint is a flat surface that is directly attached to the exterior surface of the cosmetic container using glue or tape, thereby protecting and decorating the container through first surface 20. First surface 20 is a decorative exterior surface. The shape of the patch base 10 can be adjusted to the structure of the cosmetic container, for example, it can be rectangular, square, oval, circular, etc. In addition to the patch base 10, the patch can also include other components. For example, the first surface 20 of the patch base 10 can be affixed with a protective film to protect the patch base, and the second surface 30 can be affixed with an adhesive layer to adhere the patch base to the surface of the cosmetic container. This patch has a leather-like appearance and feel. When attached to the outer surface of the cosmetic container, it not only protects the container but also gives the appearance of leather, enhancing the product's quality. This patch is made of plastic, which is more wear-resistant and elastic than leather. Compared to traditional stamped silicone substrates with imitation leather surfaces, this patch has high hardness, strong toughness, and is more durable.

[0040] As shown in Figures 1-2, adjacent raised portions 21 are connected to recessed portions 22, and the deepest portion of the recessed portion 22 is a connecting strip 23. In one possible embodiment, raised portions 21 and recessed portions 22 are provided on the first surface 20. The raised portions 21 and recessed portions 22 are arranged continuously, spaced apart, and repeatedly. A connecting strip 23 is provided at the deepest point of the recessed portion 22, i.e., the lowest point of the recessed portion as shown in Figure 4. The connecting strip 23 divides the first surface 20 into a plurality of parallel raised portions 21. Figure 1 shows four raised portions 21, but the number can be arbitrarily set as needed. Optionally, 3-8 raised portions 21 can be provided, and the lengths and widths of the raised portions can be the same or different. Optionally, the upper surface of the raised portion 21 is a curved surface that is convex toward the second surface, and the upper surface of the recessed portion 22 is a curved surface that is concave toward the second surface. The recessed portion 22 is used to connect the two raised portions 21 so that the raised portions transition smoothly, thereby forming a smooth surface. A connecting strip 23 is formed at the deepest part of the recessed portion 22 to simulate the effect of leather being divided in the middle by sewing.

[0041] Optionally, the combination of the raised portion 21 and the recessed portion 22 has a linear structure, a V-shaped structure, a W-shaped structure, a zigzag structure, or a wavy structure. In practical applications, the shapes of the raised portion 21 and the recessed portion 22 can be determined in combination with the specific shape of the patch. For example, referring to FIG1 , when the patch is square, the raised portion 21 and the recessed portion 22 can be designed as a linear, wavy, or other structure; when the patch is circular, the raised portion 21 and the recessed portion 22 can be designed as a V-shaped, W-shaped, or other structure. Of course, in order to ensure the coordination of the patch, the connecting strip structure of the recessed portion 22 is also adjusted accordingly. Optionally, the shapes of the raised portion 21, the recessed portion 22, and the connecting strip 23 remain consistent. The raised portion 21 and the recessed portion 22 can be arranged along the length direction, width direction or diagonal direction of the patch substrate. The raised portion 21 and the recessed portion 22 shown in Figure 1 are arranged straight along the length direction of the patch substrate 10. The raised portion 21 and the recessed portion 22 can also be rotated 45° clockwise or counterclockwise to arrange them along the diagonal direction of the patch substrate 10. Of course, they can also be rotated at any angle between 0-90°, or the raised portion 21 and the recessed portion 22 can be rotated 90° to arrange them along the width direction of the patch substrate 10.

[0042] The raised portion 21 and the recessed portion 22 are both arranged along the length direction of the patch substrate 10 , and both the raised portion 21 and the recessed portion 22 run through the entire or partial length direction of the patch substrate 10 . For the convenience of description, the X-axis direction in Figure 1 is defined as the length 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 Figure 1, the raised portion 21 and the depressed portion 22 are both arranged along the length direction of the patch substrate 10, and are arranged in the entire length direction, that is, along the width direction of the patch substrate 10, the raised portion 21 and the depressed portion 22 are arranged in sequence and repeatedly, and the lengths of the two are the same. Figure 4 shows a left view of the patch. It can be seen from the figure that the first surface 20 is similar to a wavy structure, the upwardly convex part is the raised portion 21, and the downwardly collapsed part is the depressed portion 22; of course, the raised portion 21 and the depressed portion 22 can also be arranged in part of the length direction of the patch substrate. Optionally, the length of the raised portion 21 (or the depressed portion 22) accounts for more than half of the total length of the patch substrate.

[0043] As shown in Figures 1-2, a circle of connecting strips 23 are provided around the edges of the first surface 20. Providing connecting strips 23 around the first surface can improve the durability of the product. The connecting strips around the edges are consistent with the connecting strips in the recessed portion, making it more beautiful and closer to the appearance of leather products.

[0044] Example 1: As shown in Figures 1-4, the top surface of the connecting strip 23 is a smooth, flat surface. The top surfaces of the connecting strip 23 in the recessed portion 22 and the connecting strips 23 around the first surface are all smooth surfaces. This structure simplifies the mold for producing a patch, reducing processing costs. Alternatively, the top surface of the connecting strip 23 includes a plurality of spaced-apart protrusions, forming an array of micro-protrusions. Example 3: As shown in Figures 9-12, the connecting strip 23 in the recessed portion and the connecting strips 23 around the first surface all include a plurality of spaced-apart protrusions that mimic the stitching structure of leather. The protrusions extend throughout the entire surface of the connecting strip 23. This structure creates a patch with a more enhanced leather-like effect. In Example 3, the first surface 20 is also provided with the letter A. This feature is described in detail below.

[0045] Optionally, the entire second surface 30 is planar, or the junction is planar, while the rest of the second surface 30, excluding the junction, is concave. In one possible embodiment, the entire second surface is planar, so that when adhered to the cosmetic container, the patch adheres strongly to the cosmetic container and is not easily removed. In another possible embodiment, only the junction is planar, while the rest of the second surface is concave. This means that the thickness of the raised portion 21 is uniform throughout. A patch with such a structure is easily injection molded and facilitates industrial production.

[0046] Example 2: As shown in Figures 5-8, a symbol 24 is provided on the first surface 20. The symbol 24 is recessed toward the second surface 30, or the symbol 24 protrudes from the raised portion 21. The symbol 24 is recessed toward the second surface 30, forming a continuous groove on the first surface 20. The continuous groove forms a symbol 24 with a certain meaning. The symbol can be any graphic. Optionally, the symbol 24 is a letter, number, Chinese character, or other special symbol. The symbol 24 is integrally injection molded with the patch substrate 10. Optionally, the symbol 24 can be a single symbol or a combination of multiple symbols. The symbol 24 shown in Figure 5 is A. In actual application, the letter A can be made into any image. The symbol 24 can be any uppercase or lowercase letter, number, Chinese character, or other special symbol. The symbol is directly formed during the molding process of the patch substrate 10, which is simple and convenient to manufacture. The patch symbol can be selected from patterns that consumers like or characters with specific meanings, thereby meeting the diverse needs of consumers. In another possible implementation, a corresponding insert can be embedded or glued into the groove formed by the symbol 24. In other implementations, the symbol 24 can also be designed to be raised, protruding from the raised portion 21, that is, the symbol is higher than the first surface 20, so that consumers can touch the symbol, making the overall structure of the patch more three-dimensional and more novel.

[0047] When the symbol 24 is recessed toward the second surface 30 , the deepest part of the recessed portion 22 is on the same level as the upper surface of the symbol 24 , forming a leather-like feel and improving the similarity to the imitation leather; the upper surface of the symbol 24 is a smooth and flat plane.

[0048] Example 4: As shown in Figures 13-14, the first surface 20 has a leather texture. Optionally, the entire first surface 20 is covered with fine leather texture. During the production process, the mold can be textured to obtain the leather texture on the first surface. Textured methods include laser texturing and chemical etching. Different texture patterns can be designed as needed to obtain the desired leather texture.

[0049] The patch substrate 10 is made of TPU, PP, PVC, or PET. 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.

[0050] Optionally, the patch substrate 10 is a TPU patch substrate, and the properties of the TPU material are as follows: density of 1.0-1.3g / cm3 Shore hardness is 60-75A, tensile strength is 10-20MPa, 100% modulus is 1.5-2.5MPa, 300% modulus is 4-6MPa, elongation at break is 600-800%, tear strength is 60-70KN / m, and abrasion resistance is 85-95mm 3 , the glass transition temperature is -45--40℃. The testing standards for various indicators of TPU material are as follows: density adopts ASTM D792 standard; Shore hardness adopts ASTM D2240 standard; tensile strength, 100% modulus, 300% modulus and tear strength adopt ASTM D412 standard; tear strength adopts ASTM D624 standard; wear resistance adopts DIN53516 standard; glass transition temperature Tg adopts differential scanning calorimetry, the condition is 10℃ / min; using TPU material with the above characteristics is the guarantee for manufacturing patches with leather feel. In one embodiment, the performance of TPU material is as follows: physical properties: density is 1.18g / cm 3 , Shore hardness is 66A; Mechanical properties: tensile strength is 17MPa, 100% modulus is 2MPa, 300% modulus is 5MPa, elongation at break is 750%, tear strength is 65KN / m, wear resistance is 90mm 3 ; Thermal properties: Glass transition temperature is -42℃.

[0051] A mold is provided for manufacturing the aforementioned patch for a cosmetic container. The patch is formed by a single injection molding process. Specifically, the patch base 10, along with the raised portion 21, recessed portion 22, connecting strip, and other features on the patch base, such as the protrusions, symbols, and leather grain, are all formed in a single injection molding process, simplifying the manufacturing process. The connecting strip, the protrusions, symbols, and leather grain features on the connecting strip can be arbitrarily combined in various embodiments, and are not limited to those described in the four aforementioned embodiments.

[0052] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
