[0037] It should be noted that the terms "first," "second," etc., in the description, claims, and figures below of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that these objects can be interchanged under appropriate circumstances, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein. Furthermore, the terms "include" and "have," and all their variants, are intended to cover non-exclusive inclusion.For example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to the clearly listed steps or units, but may include other steps or units that are not clearly listed or that are inherent in such processes, methods, products or devices.

[0038] As illustrated in Figures 1-14, a patch for cosmetic containers comprises a one-piece injection-molded plastic patch base 10. The patch base 10 comprises a first surface 20 and a second surface 30 arranged oppositely. The first surface 20 comprises alternately raised portions 21 and concave portions 22. The projection of the concave portions 22 onto the second surface 30 forms a bonding portion. This bonding portion serves to attach the patch to the cosmetic container. The first surface 20 of the patch base 10 is the outer surface, the second Surface 30 is the inner surface. The connecting part is a portion of the second surface 30. Optionally, the connecting part is a flat surface. This connecting part is directly glued to the outer surface of the cosmetic container using glue or adhesive tape, thus fulfilling the protective and decorative function of the container via the first surface 20. 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, it can be rectangular, square, oval, round, etc. In addition to the patch base 10, the patch may also include other components. For example, a protective film can be applied to the first surface 20 of the patch base 10 to protect the patch base, and an adhesive layer can be applied to the second surface 30 to adhere the patch base to the surface of the cosmetic container.This patch has a similar look and feel to leather; it is applied to the outer surface of the cosmetic container, not only to protect the container but also to give it a leather-like visual appearance, thus enhancing the product's quality. This patch is made of plastic, which is more abrasion-resistant and elastic than leather. Compared to traditional products combining an embossed silicone lining and a leather-like surface, this patch has high hardness, strong toughness, and is more durable.

[0039] As illustrated in Figures 1-2, the raised portions 21 and the adjacent concave portions 22 are connected, the deepest part of the concave portions 22 forming a connecting strip 23. In one possible configuration, the first surface 20 comprises raised portions 21 and concave portions 22, the raised portions 21 and concave portions 22 being arranged continuously, spaced, and repeated, the deepest part of the concave portions 22, i.e., the lowest point of the concave portions as illustrated in [Fig. 4], being provided with a connecting strip 23, the connecting strip 23 dividing the first surface 20 into several parallel raised portions 21, [Fig. 1] showing four raised portions 21, which can be arranged as required; optionally, there can be 3-8 raised portions 21, the length of each raised part can be identical or different, as can the width.Optionally, the upper surface of the raised parts 21 is a convex curved surface extending away from the second surface, and the upper surface of the concave parts 22 is a concave curved surface extending towards the second surface. The concave parts 22 serve to connect two raised parts 21 to form a smooth transition, thus creating a smooth surface. A connecting strip 23 is formed in the deepest part of the concave parts 22, mimicking the stitching effect of leather.

[0040] Optionally, the combination of the raised parts 21 and the concave parts 22 forms a linear, V-shaped, W-shaped, or tooth-shaped structure saw-shaped or wave-shaped. In practice, the shape of the raised parts 21 and the concave parts 22 can be determined according to the specific shape of the patch, for example, as illustrated in [Fig. 1], when the structure of the patch is square, the raised parts 21 and the concave parts 22 can be designed as linear, wavy, etc. structures; when the structure of the patch is round, the raised parts 21 and the concave parts 22 can be designed in a V, W, etc. shape. Of course, to ensure the harmony of the patch, the structure of the connecting strip of the concave parts 22 is also adjusted accordingly; optionally, the shape of the raised parts 21, the concave parts 22 and the connecting strip 23 remains consistent. The raised parts 21 and the concave parts 22 can be arranged along the direction of the length, width or diagonal of the base of the patch, [Fig. 1].[l] shows the raised parts 21 and the concave parts 22 arranged in a straight line along the direction of the length of the base of the patch 10; they can also be rotated 45° clockwise or counterclockwise to be arranged along the diagonal of the base of the patch 10; of course, they can also be rotated at any angle between 0 and 90°, or the raised parts 21 and the concave parts 22 can be rotated 90° to be arranged along the direction of the width of the base of the patch 10.

[0041] The raised portions 21 and the concave portions 22 are all arranged along the length of the patch base 10, and the raised portions 21 and the concave portions 22 cross all or part of the length of the patch base 10. For ease of description, the direction of the X-axis in [Fig. 1] is defined as the length of the patch base 10, and the direction of the Y-axis is defined as the width of the patch base 10. As illustrated in [Fig. 1], the raised portions 21 and the concave portions 22 are all arranged along the length of the patch base 10, and are arranged along its entire length; that is, along the width of the patch base 10, the raised portions 21 and the concave portions 22 are arranged alternately and in a manner repeated, with identical lengths. The [Fig.[4] shows a left view of the patch, we can see that the first surface 20 has a wave-like structure, the parts that protrude upwards are the raised parts 21, and the parts that sink downwards are the concave parts 22; of course, the raised parts 21 and the concave parts 22 can also be arranged on a part of the direction of the length of the patch base, optionally, the length of the raised parts 21 (or the concave parts 22) represents more than half of the total length of the patch base.

[0042] As illustrated in Figures 1-2, the four peripheral edges of the first surface 20 are provided with a connecting band circle 23. The presence of bands The 23 connection strips on the four sides of the first surface can improve the durability of the product; the peripheral connection strips and the connection strips of the concave parts are continuous, which is more aesthetic and closer to the appearance of leather products.

[0043] Example embodiment 1: As illustrated in Figures 1-4, the upper surface of the connecting strip 23 is a smooth and uniform flat surface, the upper surfaces of the connecting strips 23 in the concave parts 22 and of the connecting strips 23 around the first surface are all smooth flat surfaces, the mold for producing a patch with this structure is simpler, with a low manufacturing cost; or the upper surface of the connecting strip 23 comprises several protrusions arranged at intervals, the connecting strip 23 being a network of micro-protrusions.Example of embodiment 3: As illustrated in figures 9-12, the connecting strips 23 in the concave parts and the connecting strips 23 around the first surface all include several protrusions arranged at intervals to imitate the structure of the seams in leather, the protrusions crossing the entire surface of the connecting strip 23, the patch adopting this structure has a better imitation of leather effect, in example of embodiment 3, the letter A is also arranged on the first surface 20, this feature will be explained in detail below.

[0044] Optionally, the second surface 30 is generally flat, or the bonding portion is flat, and the other areas of the second surface 30, with the exception of the bonding portion, are concave. In one possible embodiment, the entire second surface is flat, so the entire second surface is bonded to the cosmetic container, the adhesion between the patch and the cosmetic container is high, and the patch does not detach easily; in another possible embodiment, only the bonding portion is flat, the other areas of the second surface are concave, i.e., the thickness of the raised portions 21 is uniform throughout, a patch with such a structure is easy to injection mold, facilitating industrial production.

[0045] Example of embodiment 2: As illustrated in Figures 5-8, symbols 24 are arranged on the first surface 20, said symbols 24 being concave towards the side of the second surface 30, or said symbols 24 projecting on the raised portions 21. The symbols 24 concave towards the side of the second surface 30 form continuous grooves on the first surface 20, these continuous grooves forming symbols 24 having a certain meaning, the symbols being able to be any shape. Optionally, the symbols 24 may be letters, numbers, Chinese characters, or other special symbols, the symbols 24 being injection-molded in one piece with the patch base 10. Optionally, the Symbol 24 can be a single symbol or a combination of several symbols. The symbol 24 shown in [Fig. 5] is an A. In practical application, the letter A can be made in any image, and symbol 24 can be any uppercase or lowercase letter, numeral, Chinese character, or other special symbol, formed directly during the molding process of the patch base 10, making it simple and convenient to manufacture. The patch symbols can be chosen according to consumers' preferred designs or characters with specific meanings, thus meeting diverse consumer needs. In another possible embodiment, corresponding inserts can be inlaid or glued into the grooves formed by the symbols 24.In other designs, the symbols 24 can also be designed in relief, with the symbols 24 protruding on the raised parts 21, i.e. the symbols are higher than the first surface 20, consumers can touch the symbols, giving the whole patch a more three-dimensional and innovative structure.

[0046] When the symbols 24 are concave towards the side of the second surface 30, the deepest part of the concave parts 22 and the upper surface of the symbols 24 are on the same horizontal plane, to create a leather feel and improve the similarity to imitation leather; the upper surface of the symbols 24 is a smooth and uniform flat surface.

[0047] Example embodiment 4: As illustrated in Figures 13-14, the first surface 20 has a leather texture. Optionally, the entire first surface 20 is covered with a fine, dense leather texture. During the manufacturing process, the leather texture on the first surface can be obtained by engraving the mold. Engraving methods include laser engraving and chemical etching; different engraving patterns can be designed as required to obtain the desired leather texture.

[0048] The patch base 10 is a patch base made of TPU material, a patch base made of PP material, a patch base made of PVC material, or a patch base made of PET material. Of these, TPU (Thermoplastic Polyurethane) is a thermoplastic polyurethane elastomer, PET (Polyethylene Terephthalate) is polyethylene terephthalate, PP (Polypropylene) is polypropylene, and PVC (Polyvinyl Chloride) is polyvinyl chloride.

[0049] Optionally, the patch base 10 is a patch base made of TPU material, and the properties of the TPU material are as follows: density of 1.0-1.3 g / cm³, Shore hardness of 60-75 A, tensile strength of 10-20 MPa, modulus at 100% of 1.5-2.5 MPa, modulus at 300% of 4-6 MPa, elongation at break of 600-800%, tear strength of 60-70 kN / m, abrasion resistance of 85-95 mm³, temperature of Glass transition temperature of -45 to -40°C. The test standards for the various indicators of the TPU material are as follows: density uses ASTM D792; Shore hardness uses ASTM D2240; tensile strength, modulus at 100%, modulus at 300%, and tear resistance use ASTM D412; tear resistance uses ASTM D624; abrasion resistance uses DIN53516; glass transition temperature (Tg) uses differential scanning calorimetry, with a condition of 10°C / min; the use of a TPU material with these characteristics guarantees the manufacture of a patch with a leather-like feel.In an example embodiment, the properties of the TPU material are as follows: physical properties: density of 1.18g / cm3, Shore hardness of 66A; mechanical properties: tensile strength of 17MPa, modulus at 100% of 2MPa, modulus at 300% of 5MPa, elongation at break of 750%, tear strength of 65KN / m, abrasion resistance of 90 mm3; thermal properties: glass transition temperature of -42°C.
