[0027] Example: Figure 1-2 As shown, a gold-stamping exterior decoration for a cosmetic container includes an exterior decoration base 10 and a gold-stamping foil layer 20. Figure 3-4 As shown, the exterior trim base 10 includes a front side 11 and a back side 12 that are arranged opposite to each other. The back side 12 is used to fit on a cosmetic container. Figure 2As shown, the gold foil layer 20 is fixedly attached to the gold foil surface of the exterior trim substrate 10, and the gold foil surface includes the front side 11 or the back side 12. The gold foil layer 20 is provided with a recessed area 21, and the recessed area 21 is embedded in the gold foil surface. In order to achieve a good visual effect, cosmetic containers usually attach exterior trims to the outer shell of the container or perform gold foil stamping directly on the outer shell, so that a gold foil layer is formed on the outer shell. When the gold foil stamping is performed directly on the outer shell, the exterior trim substrate 10 is a part of the shell, wherein the shell includes an outer cover, a bottle body, a can body, a box body, etc. Optionally, the exterior trim substrate is a sheet structure, and the exterior trim substrate 10 includes a front side 11 and a back side 12, and the back side 12 is attached to the cosmetic container. The exterior trim substrate 10 can be made of either a transparent material or an opaque material. Optionally, the exterior trim substrate 10 is made of colorless transparent plastic, colored transparent plastic or colored opaque plastic, and the colored plastic can be made by adding masterbatch to plastic particles. Optionally, the exterior trim substrate 10 is an exterior trim substrate made of TPU, PP, PVC, PET, PETG or PCR, wherein TPU (ThermoPlasticpolyUrethane) is thermoplastic polyurethane elastomer rubber, PET (PolyEthylene Terephthalate) is polyethylene terephthalate, PP (PolyPropylene) is polypropylene, PVC (PolyVinyl Chloride) is polyvinyl chloride, PETG (Poly(ethyleneterephthalateco-1,4-cylclohexylenedimethyleneterephthalate)) is polyethylene terephthalate-1,4-cyclohexane dimethanol ester, and PCR (Post-ConsumerRecycled material) is recycled plastic. In the present application, the hot stamping foil layer 20 is hot stamped on the surface of the exterior trim substrate 10 by hot stamping technology. In one possible hot stamping method, hot stamping the hot stamping foil layer 20 on the back of the exterior trim substrate 10 is called back hot stamping; in another possible hot stamping method, hot stamping the hot stamping foil layer 20 on the front of the exterior trim substrate 10 is called front hot stamping. In the present application, a recessed area 21 is provided on the hot stamping foil layer 20, and the recessed area is embedded in the front 11 or back 12 of the exterior trim substrate 10, so as to produce a three-dimensional visual effect, thereby improving the visibility and product grade of the product.
[0028] The thickness of the gold foil layer 20 can be selected as required. Optionally, the thickness of the gold foil layer 20 is 0.01 mm to 0.05 mm. Optionally, the thickness of the gold foil layer 20 is 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm or 0.05 mm. Optionally, the thickness of the gold foil layer 20 is 0.01 mm to 0.02 mm. The depth of the recessed area 21 can be adjusted according to the use requirements. Optionally, as Figure 2 As shown, the depth H of the recessed area 21 is 0.01mm to 1mm. Optionally, the depth H of the recessed area 21 is 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm. Optionally, the depth H of the recessed area 21 is 0.01mm to 0.08mm. Optionally, the depth H of the recessed area 21 is 0.08mm to 0.2mm. Optionally, the depth H of the recessed area 21 is 0.2mm to 0.5mm. Optionally, the depth H of the recessed area 21 is 0.5mm to 1mm. The gold foil layer 20 needs to be subjected to high temperature resistance treatment before being pressed together with the exterior component substrate 10 . The deeper the recessed area, the higher the requirement for the high temperature resistance of the gold foil layer 20 .
[0029] Optionally, the shape of the exterior trim base 10 includes a convex lens shape. The convex lens shape is conducive to the display of the three-dimensional hot stamping effect, and the convex lens shape includes a double convex lens shape, a plano-convex lens shape, or a concave-convex lens shape. Optionally, the shape of the exterior trim base 10 is a plano-convex lens shape, that is, the front surface 11 is a convex surface, and the back surface 12 is a flat surface, so that the back surface of the exterior trim is easily firmly combined with the cosmetic container.
[0030] Optionally, the gilded surface includes a flat surface and / or a curved surface. Since the housing of the container includes an outer cover, a bottle body, a can body, a box body, etc., the gilded exterior decoration can be attached to the surface of the outer cover, and can also be attached to the peripheral side walls of the bottle body, the can body, the box body, etc. The surface of the outer cover includes a slightly convex curved surface and a flat surface, and the structures of the bottle body, etc. include polyhedrons, cylinders, frustums of cones, etc., so the peripheral side walls of the bottle body, etc. include a curved surface with a large radian and a flat surface. In order to fit the gilded exterior decoration onto the housing of the container, correspondingly, the gilded surface of the exterior decoration substrate 10 is also designed to be a flat surface and / or a curved surface. In one possible implementation, the front surface 11 and the back surface 12 of the exterior decoration substrate 10 are both flat surfaces, and the exterior decoration substrate 10 is a flat sheet-like structure with a uniform thickness; in another possible implementation, one of the front surface 11 and the back surface 12 is a flat surface and the other is a curved surface, that is, the exterior decoration substrate 10 has a convex structure with a thick middle and a thin periphery; in yet another possible implementation, the front surface 11 and the back surface 12 are both convex curved surfaces, and the exterior decoration substrate 10 is a convex structure with a uniform thickness. Among them, the so-called uniform thickness of the exterior decoration substrate 10 means that any two points are taken on the exterior decoration substrate 10, and the difference in the thickness of the exterior decoration substrate 10 at the corresponding positions of the two points is less than the tolerance.
[0031] When the product is formed, the size, distribution and shape of the recessed area 21 can be set according to actual needs. The recessed area 21 can be several independent small areas distributed on the surface of the exterior decoration substrate 10, or can be arranged in a strip shape along the length, width or any other direction of the exterior decoration substrate 10. Optionally, the shape of the recessed area 21 includes at least one of a V shape, a U shape, a C shape and an arc shape. The so-called shape of the recessed area 21 is the shape presented by the recessed area 21 in the longitudinal section of the exterior decoration, such as Figure 2 as shown in, the recessed area 21 is V-shaped, and the longitudinal section of the gilded foil layer 20 is serrated. Of course, the recessed area 21 can also be in the shape of a U shape, a C shape, an arc shape, etc. The shapes of all the recessed areas 21 can be the same or different.
[0032] The gilded foil layer 20 is hot-pressed onto the gilded surface through a hot stamping plate 30. During the hot-pressing process, the gilded surface is in a molten state. Before hot-pressing, the gilded foil layer 20 is in a flat state. After hot-pressing, the gilded foil layer 20 forms a recessed area 21, and the recessed area 21 is embedded in the gilded surface. Before hot-pressing, the gilded foil layer 20 is a flat thin paper-like shape, and the gilded surface is a smooth surface. During the hot-pressing process, the gilded surface is heated by the hot stamping plate 30 at a high temperature to make the gilded surface in a molten state, and a part of the gilded foil layer 20 is embedded into the gilded surface by using the uneven surface of the hot stamping plate. After the hot-pressing is completed, the gilded surface cools and solidifies, and the area where the gilded foil layer 20 is embedded in the gilded surface forms a recessed area 21 embedded in the gilded surface, that is, the surfaces of both the gilded foil layer 20 and the gilded surface are uneven structures.
[0033] When the hot stamping foil layer 20 is attached to the front side 11, the exterior decoration base 10 is a transparent exterior decoration base or an opaque exterior decoration base. The method of attaching the hot stamping foil layer 20 to the front side 11 of the exterior decoration base 10 is the same as that of attaching it to the back side 12. At this time, since the hot stamping foil layer 20 is on the outside of the product, the material of the exterior decoration base 10 can be transparent or opaque, which will not affect the effect of forming a three-dimensional metal decorative surface of the product; the back side of the exterior decoration base 10 is fixed to the cosmetic container by means of clamping, bonding, fusion bonding, etc.
[0034] A transparent protective layer is sprayed on the outer surface of the hot stamping foil layer 20. After the exterior trim substrate 10 is hot stamped, the inner surface of the hot stamping foil layer 20 is bonded to the front surface of the exterior trim substrate 10, and a transparent protective layer is sprayed on the outer surface of the hot stamping foil layer 20. In this way, the three-dimensional hot stamping effect can be displayed, and the hot stamping foil layer 20 can be prevented from being scratched or abraded during use. Optionally, the protective layer includes a polymer transparent protective paint layer.
[0035] like Figure 1-2 As shown, when the hot stamping foil layer 20 is attached to the back surface 12, the exterior decoration base 10 is a transparent exterior decoration base. Since the hot stamping foil layer 20 is attached to the back surface of the exterior decoration base 10, the hot stamping foil layer with a three-dimensional hot stamping effect can only be seen through the exterior decoration body 10, so the exterior decoration base 10 is made of a transparent material.
[0036] The outer surface of the gold foil layer 20 is printed or sprayed with an ink layer. The ink layer can cover the small holes that are not formed during the gold foil stamping. Therefore, the color of the ink layer can be the same or similar to the color of the gold foil layer. Optionally, the gold foil layer on the back of the exterior trim substrate 10 is fixed to the cosmetic container by bonding. Since the ink layer is highly hydrophobic, the bonding strength between the gold foil layer and the adhesive or glue is improved.
[0037] A hot stamping plate for making hot stamping exterior parts, the hot stamping plate 30 comprises a silicone layer 31 and an aluminum layer 32 fixedly combined, the silicone layer 31 comprises an outer surface and an inner surface arranged opposite to each other, the inner surface is attached to the aluminum layer 32, and a protrusion 33 is arranged on the outer surface. When making the hot stamping plate 30, the silicone layer 31 and the aluminum layer 32 are placed together under the hot stamping plate mold and pressed by a machine, such as Figure 6As shown, a protrusion 33 is provided on the outer surface of the silicone layer 31 for making a recessed area 21 on the exterior trim. The process of making the exterior trim is explained by taking the hot stamping foil layer 20 attached to the back side 12 of the exterior trim substrate 10 as an example: when making the exterior trim, the hot stamping foil layer 20 is attached to the back side 12 of the exterior trim substrate 10, and then the silicone layer 31 of the high-temperature hot stamping plate 30 is pressed onto the hot stamping foil layer 20. The high-temperature hot stamping plate 30 melts the back side 12 of the exterior trim substrate 10, and the hot stamping foil layer is bonded to the molten exterior trim substrate 10. The hot stamping foil layer is embedded in the back side 12 of the exterior trim substrate 10 through the protrusion 33 on the silicone layer 31 to form a recessed area 21. The recessed area 21 has the same shape as the protrusion 33. Optionally, as Figure 5 As shown, the thickness D1 of the silicone layer 31 is 5±0.5 mm, and the thickness D2 of the aluminum layer 32 is 1±0.2 mm.
[0038] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these modifications and improvements are all within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the attached claims.
