2results about How to "Improve anti-counterfeiting function" patented technology

The utility model discloses a multilayer film structure based on bright surface paper, including the transparent layer, bright surface paper, adhesive layer and double glue base paper of up and down distribution, the transparent layer includes the first transparent adhesive film and second transparent adhesive film that different anti -fake marks are printed, and the first transparent adhesive film and second transparent adhesive film all are glued on the bright surface layer, and the anti -fake mark of both is not blocked each other, and the adjacent place of first transparent adhesive film and second transparent adhesive film exists the overlapping area, and both fixed connection. The utility model discloses through gluing the first transparent adhesive film and second transparent adhesive film on the bright surface layer of bright surface paper, does not influence the original luster and aesthetic feeling of bright surface paper, and through the anti -fake mark of first transparent adhesive film and second transparent adhesive film, increases the anti -fake function, in addition, because first transparent adhesive film and second transparent adhesive film fixed connection, improve the bonding strength of first transparent adhesive film and second transparent adhesive film and bright surface paper, and the combination of different anti -fake marks can improve the difficulty of counterfeiting, and easily consumer identification.

The utility model relates to an inner cap, in particular to a novel anti-pulling-off double-material injection molding type white spirit anti-fake bottle cap inner cap, and solves the design problem of preventing the inner cap from being pulled out by mistake. The inner cover comprises an inner buckle body and an outer cover body which are integrally formed through double-material injection molding, connected clamping portions are arranged between the inner buckle body and the outer cover body, the clamping portions are in a step-shaped distribution path, the number of the clamping portions is at least two in the circumferential direction, a through sealing cavity is formed in the middle of the outer cover body, and the sealing cavity is communicated with the inner buckle body and the outer cover body. The inner buckle body is provided with a protruding part extending into the sealing cavity of the outer cover body, and a gap is formed between the protruding part and the cavity wall of the sealing cavity. The pulling force of the bottle cap is greatly improved, so that the problem that the inner cap is pulled off from other components (on the inner sleeve and the upper cap) of the bottle cap under the physical force of the bottle cap is solved; the anti-counterfeiting function of the bottle cap product is greatly improved; compared with other split type anti-counterfeiting inner covers, the production cost is reduced, the production procedures are reduced, and the production efficiency is improved.
