Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, specifically a heavy-duty cosmetic bottle cap with an iron block coated with rubber. Background Technology

[0002] In the cosmetics industry, besides the efficacy of the cosmetics themselves, packaging design is also a crucial factor in attracting consumers. Increasing the weight of cosmetic bottle caps to give them a more "metallic feel" is a common design practice in the industry. Currently, the mainstream method for increasing the weight of bottle caps is to embed zinc alloy weights inside the caps. However, over time, zinc alloy weights have revealed a series of problems, such as high material and processing costs, complex and long processing cycles, and heavy metal pollution issues during the zinc alloy electroplating process. Given this situation, how to provide a new type of bottle cap that can balance increased weight, reduced costs, and simplified processes has become an increasingly urgent problem for relevant technical personnel to solve. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a heavy-duty cosmetic bottle cap with an iron block coated with rubber.

[0004] A heavy-duty cosmetic bottle cap with an iron block coated with rubber includes an outer cap and an inner cap, characterized in that: the inner cap is located inside the outer cap, an iron block is disposed above the inner cap, an iron block is disposed outside the iron block, and the iron block, the iron block, the iron block, and the outer cap are an integral structure.

[0005] Furthermore, a lower snap-fit ​​part is provided on the lower part of the outer wall of the inner cover, and a snap-fit ​​groove is provided on the lower part of the inner wall of the outer cover, and the lower snap-fit ​​part snaps into the snap-fit ​​groove.

[0006] Furthermore, the outer wall of the inner cover is bonded to the inner wall of the outer cover.

[0007] Furthermore, the inner wall of the inner cover has an upper snap-fit ​​portion arranged in a ring array in the middle, and the upper snap-fit ​​portion protrudes inward with a horizontal and curved design.

[0008] Furthermore, patches are symmetrically fixedly arranged on the upper part of the outer cover.

[0009] The beneficial effects of this utility model of a heavy-duty cosmetic bottle cap with a rubber-coated iron block are as follows: 1. The combination of iron block and rubber-coated block achieves the expected effect of increasing the weight of bottle cap without the need for complex processes such as polishing and electroplating as zinc alloy weighting parts. The process is simplified and there is no longer the problem of heavy metal pollution caused by electroplating. In terms of material cost, iron is significantly lower than zinc alloy. Therefore, the bottle cap of this application well meets the processing requirements of "balancing increased weight, reduced cost and simplified process". 2. The integrated design of the iron block, rubber-coated block, and outer cap, the snap-fit ​​of the lower locking part with the slot, and the bonding of the outer wall of the inner cap with the inner wall of the outer cap effectively ensure the stability of the bottle cap as a whole.

[0013] To make the explanation clearer, the present invention provides a further description of a heavy-duty cosmetic bottle cap with an iron block coated with rubber, in conjunction with the accompanying drawings.

[0014] A heavy-duty cosmetic bottle cap with an iron block coated with rubber includes an outer cap 5 and an inner cap 6. The inner cap 6 is located inside the outer cap 5, an iron block 7 is disposed above the inner cap 6, and a rubber-coated block 8 is disposed outside the iron block 7. The iron block 7, the rubber-coated block 8, and the outer cap 5 are an integral structure.

[0015] Furthermore, a lower snap-fit ​​part 10 is provided on the lower part of the outer wall of the inner cover 6, and a snap-fit ​​groove is provided on the lower part of the inner wall of the outer cover 5, and the lower snap-fit ​​part 10 snaps into the snap-fit ​​groove.

[0016] Furthermore, the outer wall of the inner cover 6 is bonded to the inner wall of the outer cover 5.

[0017] Furthermore, the inner wall of the inner cover 6 has an upper snap-fit ​​portion 11 arranged in a ring array in the middle, and the upper snap-fit ​​portion 11 is horizontal and curved and protrudes inward.

[0018] Furthermore, patches 4 are symmetrically fixedly arranged on the upper part of the outer cover 5.

[0019] The working principle of this utility model of a heavy-duty cosmetic bottle cap with a rubber-coated iron block is as follows: In the application scenario corresponding to this application, a bottle shoulder 2 is fixedly provided on the upper part of the bottle body 1 of the cosmetic packaging bottle. An outwardly protruding part 9 is provided on the upper part of the bottle shoulder 2. When the bottle cap 3 is connected to the bottle body 1, the upper snap-fit ​​part 11 snaps into the outwardly protruding part 9. When cosmetics are needed, the bottle cap 3 is simply removed; after use, the bottle cap 3 is simply put back on. The horizontal state and curved surface design of the upper snap-fit ​​part 11 ensure both stability of the snap-fit ​​with the outwardly protruding part 9 and... To ensure smooth removal and fastening, the combination of the iron block 7 and the rubber-coated block 8 increases the overall weight of the bottle cap 3, allowing the bottle cap 3 to achieve the expected "metallic texture". In actual processing, the bottle cap 3 needs to go through the following process: the iron block 7 is stamped and formed; the iron block 7 is placed into the mold of the rubber-coated block 8 and then injection molded to form the rubber-coated block 8; the rubber-coated block 8 is placed into the mold of the outer cap 5 and then injection molded to achieve an integrated design with the outer cap 5; the lower snap-fit ​​part 10 snaps into the slot; the inner cap 6 and the outer cap 5 are glued together to finally form the bottle cap 3.

[0020] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
