Description

Technical Field

[0001] The utility model relates to the packaging of cosmetic packaging bottles, in particular to an oil-controlling three-dimensional aluminum foil. Background Art

[0002] Cosmetic packaging sealing is a mandatory quality standard in the cosmetics industry. Currently, the sealing methods for cosmetic bottle mouths are mainly divided into gasket sealing and mechanical sealing, among which gasket sealing is the most widely used.

[0003] Gasket sealing methods primarily include electromagnetic induction gasket packaging, pressure-sensitive adhesive gasket packaging, and foamed PE gasket packaging. Due to the varying cosmetic materials used in the packaging, some water-based cosmetics, being relatively thin, typically do not stick to the packaging when the gasket is removed. However, for cosmetics with specialized materials, such as oil-based foundation packaging, conventional gasket sealing can cause the oil stuck to the bottom of the gasket to easily flow out and overflow when unsealed, potentially spilling onto the user's hands and staining the bottle mouth and body, impacting the user's experience. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an oil-controlling three-dimensional aluminum foil which can effectively prevent the sticky materials in oily cosmetics from flowing out.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The invention discloses an oil-controlling three-dimensional aluminum foil, which is composed of a sealing film and a cotton sheet layer adhered to the bottom surface of the sealing film; the sealing film is composed of an aluminum foil layer and a polyester film and a polyethylene film respectively covered on the upper and lower surfaces of the aluminum foil layer.

[0007] Furthermore, the sealing film and the cotton sheet layer are both circular in structure, the cotton sheet layer is concentrically arranged with the sealing film, and the diameter of the cotton sheet layer is smaller than that of the sealing film, and the bottom surface of the cotton sheet layer located at the periphery of the cotton sheet layer constitutes a hot-melt portion of an annular structure.

[0008] Furthermore, the outer periphery of the sealing film is provided with folding ears which protrude outwards and are formed integrally therewith.

[0009] Furthermore, the cotton sheet layer and the sealing film are bonded together by a double-sided adhesive layer.

[0010] Furthermore, the thickness of the polyester film is 12 μm, the thickness of the aluminum foil layer is 50 μm, and the thickness of the polyethylene film is 40 μm.

[0011] Furthermore, the double-sided adhesive layer is composed of tissue paper and high-performance acrylic resin layers coated on the upper and lower surfaces of the tissue paper.

[0012] Furthermore, the thickness of the tissue paper is 30 μm, and the thickness of the high-performance acrylic resin layer is 28 μm.

[0013] Compared with the existing technology, the advantages of the present invention are: this oil-control three-dimensional aluminum foil is provided with a cotton sheet layer on the bottom surface of the sealing film, and the oily cosmetics adhered to the cotton sheet layer are not easy to flow out when unsealed due to the adsorption of the cotton sheet layer, thereby ensuring that such oily cosmetics will not be stained on the user's hands and the outside of the packaging bottle when unsealed, avoiding the phenomenon of dirt, having a better oil-control effect, and convenient packaging.

The bottom surface of the cotton sheet layer 2 is located at the outer periphery of the cotton sheet layer 2. The part of the hot-melt portion 100 of the annular structure, and the hot-melt portion 100 can be attached to the top circle outside the opening of the cosmetic packaging bottle and sealed together by a hot-melt machine; in order to facilitate the removal of the sealing film 1 from the bottle mouth of the cosmetic packaging bottle, the outer periphery of the sealing film 1 is provided with a folding ear 10 protruding outward and integrally formed therewith. The shape and size of the folding ear can be designed according to actual needs, so that the user can manually remove the sealing film 1.

[0028] In order to ensure that the sealing film 1 is effectively heat-sealed with the mouth of the cosmetic packaging bottle and is easy to remove, refer to the instructions for Figure 4 As shown, the sealing film 1 is composed of an aluminum foil layer 12 and a polyester film 11 and a polyethylene film 13 respectively laminated on the upper and lower surfaces of the aluminum foil layer 12. The thickness of the polyester film 11 is 12 μm, which is convenient for embossing or printing of graphic information on its surface. The thickness of the aluminum foil layer 12 is 50 μm, which has the effects of blocking light, water and oxygen. The thickness of the polyethylene film 13 is 40 μm, which is convenient for hot-melt packaging. The aluminum foil layer 12 is bonded to the polyester film 11 and the polyethylene film 13 by a polyurethane two-component hot-melt adhesive. The coating thickness of the adhesive is usually between 2 and 4 μm.

[0029] The manufacturing method of this oil-control three-dimensional aluminum foil is as follows:

[0030] 1. First, use a laminating machine to assemble and laminate the cotton sheet or oil-control cloth with the double-sided tape, and then roll it up;

[0031] 2. Then punch and cut the cotton sheet or oil-control cloth roll with double-sided tape after lamination into shapes of corresponding sizes;

[0032] 3. Then, attach the cut cotton sheet or oil-control cloth to the sealing film 1;

[0033] 4. After the cotton sheet or oil-control cloth is laminated to the sealing film 1, a die cutter is used to die-cut the laminated composite material to complete the processing and manufacturing of the oil-control three-dimensional aluminum foil.
