Description

Technical Field

[0001] The utility model relates to the technical field of wine bottle caps, and more specifically to an anti-pulling wine bottle cap. Background Art

[0002] In the prior art, the internal components of the anti-counterfeit bottle cap are all made of plastic injection molding. The anti-counterfeit bottle cap and the bottle mouth are fixed by a connection structure that is difficult to disassemble. Forcibly pulling out the bottle cap will cause the bottle cap to be damaged. Although it has the function of anti-counterfeiting when the cap is opened, it cannot prevent the counterfeiting of replacing the wine after the bottle cap is pulled out as a whole. Due to the characteristics of plastic, unscrupulous vendors can heat the bottle cap to put it in a high temperature environment, and use equipment to evenly pull the bottle cap away from the bottle mouth as a whole. Specifically, the teeth of the inner sleeve soften in a high temperature environment so that it can be separated from the bottle mouth, resulting in failure of the connection between the bottle cap and the bottle mouth, and then the wine is replaced and counterfeited before the bottle cap is installed. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 As shown, this embodiment discloses an anti-pulling wine bottle cap, including an inner sleeve 1, a metal ring 2, an inner plug 3, an inner cover 4, an outer shell 5, and an outer cover 6. The metal ring 2 is fixedly installed on the inner sleeve 1, the inner plug 3 is installed inside the inner sleeve 1, and the inner cover 4 is fixedly installed on the upper end of the inner sleeve 1. The structure of the inner cover 4 is the prior art and is not repeated here. The outer shell 5 is fixedly installed on the outer wall of the inner sleeve 1. The outer shell 5 closes the slot 11, which plays a role in beautifying and protecting the structure of the inner sleeve 1. If the inner sleeve 1 is to be separated from the bottle 7, the outer shell 5 can only be destroyed. The outer cover 6 is installed on the outer shell 5. The outer cover 6 covers the inner cover 4 and part of the inner sleeve 1 to protect the inner cover 4 and the inner sleeve 1.

[0025] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, at least one slot 11 is provided on the side wall of the inner sleeve 1. In this embodiment, there are four slots 11, which are evenly distributed along the circumferential direction of the inner sleeve 1. The slots 11 penetrate the inner wall and the outer wall of the inner sleeve 1. The inner edges of the side walls of the slots 11 are inclined toward the center position so that the horizontal width of the slots 11 gradually decreases inwardly. The horizontal width of the inner end of the slots 11 is smaller than the horizontal width of the outer end. The inner sleeve 1 includes at least one card plate 12. The number of the card plates 12 corresponds to the number of the slots 11, which is four. There is a card plate 12 corresponding to each slot hole 11. The card plate 12 is located at the lower edge of the slot hole 11, extends upward, and the upper end of the card plate 12 is inclined toward the central axis direction of the inner sleeve 1. The card plate 12 has elastic deformation ability. The bottle lip 71 of the bottle 7 is installed into the inner sleeve 1 from the lower end of the inner sleeve 1. The bottle lip 71 presses the card plate 12 to deform so that the bottle lip 71 passes over the card plate 12, and then the card plate 12 is deformed and restored. The upper end surface of the card plate 12 presses against the lower end surface of the bottle lip 71, so as to limit the inner sleeve 1 and the bottle 7 in the up and down directions.

[0026] More preferably, the width of the card plate 12 gradually decreases from bottom to top, so that the lower end of the card plate 12 is more firmly connected, and the upper end of the card plate 12 is more easily pressed by the bottle lip 71 to be elastically deformed.

[0027] like Figure 2 , Figure 5As shown, the inner wall of the inner sleeve 1 is provided with a limiting strip 13, and the limiting strip 13 is arranged along the height direction of the inner sleeve 1. A limiting groove 131 is formed between two adjacent limiting strips 13, and the outer wall of the bottle 7 is provided with a limiting block 72 corresponding to the limiting groove 131, so that the rotation direction between the inner sleeve 1 and the bottle 7 is limited, so that the inner sleeve 1 and the bottle 7 are fixedly connected.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the metal ring 2 and the inner sleeve 1 are integrally formed by injection molding, and part of the metal ring 2 is located inside the side wall of the inner sleeve 1. The metal ring 2 is provided with at least one card flap 21, and one card flap 21 corresponds to one card plate 12. The card flap 21 is located inside the card plate 12. The metal ring 2 is injection molded inside the side wall of the inner sleeve 1, and the card flap 21 is injection molded inside the card plate 12. When the inner sleeve 1 is injection molded, the card plate 12 covers the card flap 21 inside. Since the degree of thermal deformation of the metal is small, the deformation strength of the card plate 12 can be enhanced to prevent the card plate 12 from being easily deformed and pulled out after being softened by heat in a high temperature environment.

[0029] More preferably, the card plate 12 is provided with a through hole 121, which passes through the inner and outer sides of the card plate 12, and is located in the middle of the card plate 12. The through hole 121 provides space for the card plate 12 and the card flap 21 to elastically deform outward, thereby preventing the bottle lip 71 from pressing against the card plate 12 and causing it to break.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, a portion of the upper end of the inner plug 3 is interference fit with the inner wall of the inner sleeve 1, and a shoulder 31 is provided on the side wall of the inner plug 3. The upper end surface of the shoulder 31 abuts against the inner wall of the inner sleeve 1, and the shoulder 31 provides a limit for the installation depth of the inner plug 3 in the inner sleeve 1. The inner plug 3 includes a skirt 32, and the skirt 32 is located at the lower end surface of the shoulder 31. The clamping plate 12 is located below the skirt 32. The inner plug 3 is installed into the inner sleeve 1 from the lower end of the inner sleeve 1, and the skirt 32 presses the clamping plate 12 to elastically deform each other so that the inner plug 3 is installed in the inner sleeve 1, and the upper end surface of the clamping plate 12 forms a limit for the downward direction of the skirt 32.

[0031] More preferably, the skirt 32 extends downward, and is in the shape of a trumpet with a diameter gradually increasing from top to bottom. The skirt 32 has an interference fit with the inner wall of the inner sleeve 1, and the skirt 32 and the inner wall of the inner sleeve 1 form a guide, so that the inner plug 3 can move along the inner wall of the inner sleeve 1 to provide a guide for the installation of the inner plug 3.

[0032] like Figure 1 , Figure 2 , Figure 5As shown, the outer wall of the inner plug 3 is provided with at least one ring plate 33, the ring plate 33 is located below the shoulder 31, the ring plates 33 are arranged along the length direction of the inner plug 3, the lower end of the inner plug 3 is inserted into the bottle 7, and the ring plate 33 and the inner wall of the bottle mouth of the bottle 7 are interference fit to make the outer wall of the inner plug 3 and the inner wall of the bottle mouth of the bottle 7 sealed.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
