Description

Anti-shock anti-theft cap

Technical field

The invention relates to a bottle cap, in particular to an anti-shock anti-theft bottle cap.

Background technique

The safety ring of the bottle cap of the existing large-capacity bottles (such as 4L oil bottle, 4L mineral water bottle, etc.) is generally designed as a sawtooth blade type or a buckle-type anti-theft structure, and the safety ring of the bottle cap is subjected to force in each separate On the force surface, it is easy to cause uneven force. When the bottle has a large upward pressure on the bottle cap, it is easy to loosen the safety band on the bottle cap, and even the safety band is detached from the positioning ring of the bottle. Especially in the transportation process, the liquid contained in the large-capacity bottle tends to have a strong impact on the cap, and the collision between the bottles causes a large pressure on the cap, which easily leads to deformation of the safety belt on the cap. Loose or loose, so that the bottle cap loosening causes the liquid in the bottle to leak, and the bottle cap is exploded more seriously.

Summary of the invention

In view of the above problems in the prior art, the technical problem to be solved by the present invention is to provide an anti-shock anti-theft bottle cap, which is easy to assemble quickly and labor-savingly, can withstand the upward pressure from the inside of the bottle, and avoid loosening of the cap. Or the phenomenon that the cap is squeezed out, has good anti-punching performance and anti-theft performance.

The technical solution of the present invention is as follows: an anti-shock anti-theft bottle cap, comprising a cap body with an internal thread, and a safety loop integrally molded with the cap body, between the cap body and the safety loop band The utility model is provided with a ring-cutting slit, wherein the ring-shaped slit is provided with a plurality of connecting bridges connecting the cap body and the safety ring, and an annular anti-theft skirt integrally formed with the cap body and the safety ring. The annular anti-theft skirt is reversibly connected to the edge of the safety loop, the annular anti-theft skirt forming a ring flange on the inner side of the safety loop and the two are connected at an obtuse angle, and the inner ring of the annular anti-theft skirt The ring is adjacent to the center line of the cap, and the outer ring of the annular anti-theft skirt is connected with the safety loop, and a wedge-shaped lug is formed on the surface of the annular anti-theft skirt facing away from the inner cavity of the cap. Between the adjacent wedge-shaped bumps is a thin-walled portion, the wedge-shaped convex block has a wedge-shaped convex structure, the high-end of the wedge-shaped convex structure is close to the inner ring, and the lower end of the wedge-shaped convex structure is close to the outer ring .

The thickness of the annular anti-theft skirt is not uniform. When the annular anti-theft skirt is turned over, the thin-walled part is easy to expand and contract, so that the circular anti-theft skirt has small contraction tension, easy to be flanged and assembled smoothly; when the cap is tightened, the ring anti-theft The skirt can play a better guiding and guiding effect, so that the cap can be easily screwed onto the bottle; when the cap is screwed into place and installed on the bottle, when the cap is subjected to the upward pressure of the liquid inside the bottle, the annular anti-theft skirt Abutting against the positioning ring of the bottle, the annular anti-theft skirt and the safety loop form a triangular area, and the annular anti-theft skirt is clipped under the positioning ring by a triangular conical shape, the triangular structure is stable, the cap body is not easily deformed or loosened; and the wedge-shaped lug The two corners of the high-end wedge-shaped projection abut against the mouth of the bottle, and the inner corner of the safety loop belt abuts against the positioning ring, and the outer corner of the safety belt is away from the outer wall of the bottle mouth below the positioning ring, Forming a triangular structure; when the anti-theft skirt is subjected to the pressure of the positioning ring and is intended to be turned downward, that is, the angle between the anti-theft skirt and the safety loop has a tendency to become larger, due to the high-end outer corner of the wedge-shaped projection It is placed on the outer wall of the bottle mouth, so that the anti-theft skirt can not be deformed and reversed, and the annular anti-theft skirt and the safety ring are evenly stressed, which can effectively avoid the phenomenon that the bottle cap is loosened and the bottle liquid is leaked or the cap is squeezed. Good resistance to stamping and anti-theft.

Further, the thickness of the lower end of the wedge-shaped protrusion of the wedge-shaped bump is the same as the thickness of the thin-walled portion, and the thickness of the high-end of the wedge-shaped protrusion of the wedge-shaped protrusion is 2-3 times of the thickness of the thin-walled portion.

Further, the safety loop belt has a taper shape, and the thickness of the bottom of the safety loop belt is 1.2-1.5 times of the thickness of the top portion, so that the safety loop belt can withstand a large impact force, is not easily deformed or damaged, and enhances the stamping resistance of the bottle cap. Performance and anti-theft performance.

Further, the outer side wall of the cap body is provided with a plurality of axially parallel and uniformly spaced raised anti-slip ribs, and the distance between the roots of the adjacent anti-slip ribs is smaller than the width of the root of the single anti-slip rib, and the anti-slip is provided. The ribs increase the grip of the cap, making it easy to assemble the cap.

Further, the internal thread of the cap body is double-threaded, which can reduce the stroke of the knob and facilitate quick assembly of the cap.

Further, when the opening of the cap body is facing downward, the angle between the upper surface of the thread of the internal thread and the horizontal plane is 37-43 degrees, and the angle between the lower surface of the thread and the horizontal plane is 12-18 degrees. Moreover, the thread top of the internal thread and the root of the thread are all rounded transitions, the inclination angle of the inclined surfaces on both sides of the thread is large, the cap body is easy to demould when the mold is being pulled, and the friction is stronger when the cap is tightened. Small, when the cap is subjected to a large impact force, it can avoid the stress concentration and cause the sliding teeth to deform or the teeth to collapse, which helps to improve the stamping resistance of the cap.

The invention has the beneficial effects that the invention is easy to assemble quickly and labor-savingly, and after the cap is tightened, the annular anti-theft skirt and the safety loop form a stable triangular zone, and the annular anti-theft skirt is clamped in the positioning ring by a triangular cone-shaped bottle. When the cover is subjected to the upward pressure from the inside of the bottle, the annular anti-theft skirt and the safety ring are evenly stressed, and the cap body is not easily deformed or loosened, which can effectively avoid the phenomenon that the cap is loose or the cap is squeezed, and has good performance. Anti-punching performance and anti-theft performance.
