Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-theft cap technology, and more specifically, to an anti-theft bottle cap structure. Background Technology
[0002] Anti-theft bottle caps are a common form of packaging for bottles, widely used in daily life. Their sealing and anti-theft features ensure the safety of the food inside the bottle. Consumers can check the anti-theft structure of the cap from the outside to determine if it has been opened. Existing anti-theft caps often have anti-theft components on the inside of the cap to achieve the anti-theft effect. However, during the opening process, some components or debris may fall into the bottle, contaminating the contents. Therefore, we propose a new anti-theft bottle cap structure. Utility Model Content

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.
[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] like Figure 1As shown, this utility model provides an anti-theft bottle cap structure, including: an upper cap 1 and a lower cap 2; the upper cap 1 is foldable and covers the lower cap 2; characterized in that an anti-theft structure 3 is provided at the lower end of one side of the upper cap 1; the lower cap 2 is provided with a receiving cavity 4 for housing the anti-theft structure 3; the side wall of the receiving cavity 4 is provided with a snap fastener 5 for engaging with the anti-theft structure 3; the anti-theft structure 3 includes: a plurality of tearing teeth 31 and a fixing block 32; the plurality of tearing teeth are equidistantly arranged on the top of the fixing block 32. The upper ends of the several tearing teeth 31 are respectively connected to the upper cover 1; the fixing block 32 is provided with a latch 33 adapted to the buckle 5; the buckle 5 is fastened to the fixing block 32 through the latch 33; the fixing block 32 is suspended in the accommodating cavity 4 by the cooperation of the tearing teeth 31 with the upper cover 1; when the upper cover 1 and the lower cover 2 are open, the tearing teeth 31 tear the upper cover 2, and the fixing block 32 and the tearing teeth 31 fall to the bottom of the accommodating cavity 4 to play an anti-theft role.
[0022] In this embodiment, as Figure 1-3 As shown, the opening size of the latch 33 is larger than that of the inverted buckle 5 so that the inverted buckle 5 can be movably housed in the latch 33 of the fixing block 32. During assembly, the rear ends of the upper cover 1 and the lower cover 2 can be folded together, and the fixing block 32 of the anti-theft structure 3 is placed in the receiving cavity 4 and fastened together with the inverted buckle 5. Then, the bottom of the teeth on the fixing block 32 is bonded to the bottom of one side of the upper cover 1 using hot melt adhesive or glue, so that the fixing block 32 is suspended in the receiving cavity 4, realizing the assembly operation of the anti-theft cover. Since there is a certain gap between the top of the inverted buckle 5 and the top inner wall of the latch 33, when the upper cover 1 is opened, the fixing block 32 and the tearing teeth 31 on its upper end face fall into the receiving cavity 4 under the pull of the inverted buckle 5. Therefore, after the cover is opened and closed, the anti-theft ring sinks, which can clearly distinguish whether the cover is opened for the first time, thus achieving the purpose of anti-theft. It can also prevent the parts or waste of the anti-theft structure 3 from falling into the packaging bottle and contaminating the contents during the opening process.
[0023] In one embodiment, such as Figure 3-4 As shown, the lower cover 2 has a discharge nozzle 6 on its upper opening; the inner side of the upper cover 1 is provided with a sealing structure 7 for sealing the discharge nozzle 6; by setting the sealing structure 7, leakage of the contents of the packaging bottle can be avoided.
[0024] In one embodiment, such as Figure 1-3 As shown, the outer wall of the front end of the upper cover 1 is provided with a first arc surface structure 8; the outer wall of the front end of the lower cover 2 is provided with a second arc surface structure 9 that is symmetrical to the first arc surface structure 8; specifically, both the first arc surface structure 8 and the second arc surface structure 9 are concave arc surface structures for use in opening the cover.
[0025] In one embodiment, such as Figure 1-3 As shown, the rear end of the upper cover 1 is provided with a first outwardly protruding skirt 10; the rear end of the lower cover 2 is provided with a second outwardly protruding skirt 11; the first skirt 10 and the second skirt 11 are symmetrically arranged; both the first skirt 10 and the second skirt 11 are made of flexible material; the flexible skirt can prevent the upper cover 1 from folding at too large an angle during the folding process, thereby reducing its service life.
[0026] This utility model discloses an anti-theft bottle cap structure with a stable overall structure and convenient installation. The anti-theft structure is set on the outside and is fastened with an inverted buckle. When the cap is opened, the anti-theft structure can be stored in the cavity of the lower cap, which can effectively prevent contamination of the contents of the bottle. At the same time, it can prevent the anti-theft ring from falling off due to collisions and scratches during transportation.
[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
