Description

Side-opening welding cover with anti-theft function Technical Field The utility model relates to the technical field of bottle caps, in particular to a side-opening welding cap with an anti-theft function. Background In the field of food packaging, the safety, ease of use and structural stability of the closure are important design considerations. Although the existing bottle cap has a basic anti-theft function, the following technical problems generally exist: (1) The traditional anti-theft ring structure cannot clearly display whether the package is opened or not, and the risk of tampering or misuse of the content exists. (2) The structural design defect causes inconvenience in use, for example, the matching area of the handle and the anti-theft ring is easy to be blocked or loosened due to wiring, so that the operation smoothness of a user is influenced, the package is possibly scratched or the hand is possibly scratched by the corner of the hinge part in use, and the folding resistance of the bending part is insufficient, so that the opening stability is poor. (3) The functional design is lacking, the flow of the content is not easy to control due to the lack of a guiding structure during pouring, the edges are sharp, scratches are easily caused, and the contact area of the hands is insufficient, so that the opening experience is affected. In view of the above-mentioned problems, there is a need for an improved bottle cap, which can enhance the anti-false touch and anti-tamper functions and optimize the structural design to improve the safety, stability and operation convenience. Disclosure of utility model The utility model aims to provide a side-opening welding cover with an antitheft function, which is used for solving at least one technical problem existing in the background technology. The technical aim of the utility model is realized by the following technical scheme: The anti-theft side-opening welding cover comprises a cover body and a base, wherein the cover body is matched with the base, the base is used for being connected with a packaging bag, a hinge structure is arranged between the cover body and the base, the hinge structure is fixedly connected with the cover body and the base, a tearing anti-theft ring is arranged on the base, the lower edge of the tearing anti-theft ring is connected to the base through a tearing structure, a clamping block matched with the tearing structure is arranged at the lower edge of the cover body, and the clamping block is clamped on the tearing structure of the tearing anti-theft ring. Optionally, the upper edge of the cover is outwardly convex to form a cornice for increasing the contact area of the hand to facilitate opening the cover. Optionally, handles are arranged at two ends of the tearing anti-theft ring, and the outer wall of the cover body is inwards sunken to form an anti-theft ring groove for accommodating the tearing anti-theft ring and the handles. Optionally, the tear-off anti-theft ring and handle are wrapped under the cornice. Optionally, the hinge structure comprises a circular arc-shaped main hinge and two bendable side hinges respectively positioned at two sides of the main hinge, wherein the upper edges of the main hinge and the side hinges are fixedly connected with the cover body, and the lower edges of the main hinge and the side hinges are fixedly connected with the base. Optionally, the discharge hole of the base is provided with a guiding edge part which is beneficial to the flow of the content and further adjusts the dumping amount of the content. Optionally, the guiding edge part is opposite to the hinge structure to facilitate pouring the content, and the connecting line between the guiding edge part and the hinge structure is in the same direction as the length direction of the base. Optionally, a sealing plug ring for movably sealing the discharge hole of the base is arranged in the cover body. In summary, the utility model has the advantages that when the tearing anti-theft ring is not torn, the cover body can be prevented from being opened by mistake, whether the package is opened or not can be fully identified through structural damage, safety and state identification degree are improved, secondly, the design that the tearing anti-theft ring is completely wrapped at the cornice part of the cover can avoid the clamping and loosening of the handle during wiring, operation smoothness is optimized, furthermore, the design of the edge of the main hinge is in a large radian, the utilization angle is reduced to avoid the wiring to scratch the bag, meanwhile, the side hinge bending position modeling enhances the stability and folding resistance of the opening of the cover body, the guiding edge part design can guide the content to flow and control the dumping amount when the side is reversed, scratch problem caused by sharp edge is avoided to a certain extent, and the design of the arc of the cornice part of the cover increases th
