An opening marking device is made of flexible materials and is a ring form formed by a waistband ring wall, an arc-shaped connecting ring and a wing panel shape hook type ring. The wing panel shape hook type ring is connected with the waistband ring wall through the arc-shaped connecting ring, and is in a state of bending upwards opposite to the waistband ring wall along the arc-shaped connecting ring. The end portion of the wing panel shape hook type extends to form a step type auxiliary position small wing. The opening marking device is connected with a top sealing part through a plurality of bridge connecting points. A plurality of discharging holes are distributed at the arc-shaped connecting ring and the wing panel shape hook type ring. The device marks containers which have been opened through destructive fractures of bridge connecting points, marking function is simple and reliable, and production is simplified due to application of one-step molding technology. The opening marking device is one part of a container closing device, and is molded into one with the container closing device. The device has the advantages of simplifying production process, reducing investment of relative devices, lowering process loss directly, and improving first-time qualified rate of products.
Description
technical field [0001] The invention relates to an anti-theft device for marking that the container has been opened after the container with a mouth diameter of 25-30 mm is closed. Background technique [0002] The invention is suitable for marking that the seal of the plastic container has been broken, and prompting that the product has been opened. [0003] Currently commonly used container opening and marking devices include plastic film, pull ring, etc. The container closing device and the opening and marking device need to be produced separately using two different production processes and production equipment. In the production process of the closed container, it is necessary to close the container first and then install the opening identification device in two production processes to complete. The process is complicated and the cost is higher. Contents of the invention [0004] The present invention is realized through the following technical solutions. [0005] ...
