A shock-resistant anti-theft bottle cap

Abstract

An anti-impact theftproof bottle cap comprises a bottle cap body (1) provided with internal threads, a safety ring belt (2), and an annular theftproof surrounding (4) that are subjected to integral injection molding. A ring kerf (3) is disposed between the bottle cap body (1) and the safety ring belt (2). The ring kerf (3) is provided with a plurality of connecting bridges (31) at equal intervals. The annular theftproof surrounding (4) is reversibly connected to the edge of the safety ring belt (2). The annular theftproof surrounding (4) forms a flange in the inner side of the safety ring belt (2), and the annular theftproof surrounding (4) is connected to the safety ring belt (2) in an obtuse angle manner. An inner ring of the annular theftproof surrounding (4) is close to the center line of the bottle cap, and an outer ring of the annular theftproof surrounding (4) is connected to the safety ring belt (2). Wedge-shaped lugs (41) that are distributed in a spaced manner are formed in the surface of the annular theftproof surrounding (4) away from the inner cavity of the bottle cap. A thin-wall portion (42) is formed between the two adjacent wedge-shaped lugs (41). The wedge-shaped lugs (41) are of a wedge-shaped protrusion structure. The high end of the wedge-shaped lug structure is close to the inner ring, and the low end of the wedge-shaped lug structure is close to the outer ring. The bottle cap can bear the upward stamping force from the interior of a bottle and prevent the bottle cap from being loosened, and has good anti-stamping performance and theftproof performance.

Description

technical field [0001] The invention relates to a bottle cap, in particular to an impact-resistant and anti-theft bottle cap. Background technique [0002] The safety rings of the bottle caps of existing large-capacity bottles (such as 4L motor oil bottles, 4L mineral water bottles, etc.) are generally designed as sawtooth blade-type or buckle-type anti-theft structures, and the force of the safety rings of the bottle caps is in each separate bearing. On the force side, it is easy to cause uneven force. When the inside of the bottle produces a large upward punching force on the bottle cap, it is easy to deform and loosen the safety ring on the bottle cap, and even the safety ring is detached from the positioning ring of the bottle. Especially during the transportation process, the liquid contained in the large-capacity bottle is likely to have a strong impact on the bottle cap, and each bottle collides with each other to generate greater pressure on the bottle cap, which is ...

Loose or loose, making the bottle cap loose and causing the liquid in the bottle to leak, and more seriously, the bottle cap will be squeezed and burst
