Abstract
The utility model relates to a reverse buckling preventing bottle cover. The interior of the reverse buckling preventing bottle cover is provided with a single thread, and is connected with a reverse buckling preventing ring by a connection point. The interior of the reverse buckling preventing ring is provided with double threads. The utility model has the advantages of simple structure, convenient installation and processing, low cost, and labor-saving and convenient use.
Description
The utility model belongs to a kind of bottle cap.
At present, a kind of employing metal stamping of common anti-back-off bottle cap drawing and forming; Another kind is the machinework moulding of plastic injection-moulded back, and its anti-back-off circle is connected with the lid point-like, and closes up after anti-back-off circle and the pressurization of whorl of bottleneck bottom, and this structure easily makes screw thread dropout bottle cap twist not get off, and it is complicated that mechanization is produced.
The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby provides a kind of being convenient to install, and can effectively prevent the bottle cap of back-off.
The purpose of this utility model realizes in the following way:
Have single screw thread (3) in this bottle cap (1), and connect anti-back-off circle (4), wherein: have two screw threads (5) in the anti-back-off circle (4) by point of connection (2).
During use, because connecting, point has compressibility, two screw threads can push successively and be inserted in the bottleneck single screw thread, thereafter be the bottle cap screw thread, after anti-back-off circle rotation was through the whorl of bottleneck section, bottle cap was tightened, when unscrewing bottle cap, the first head of two spiral shells is gone into bottleneck spiral shell button earlier and is moved up, the other end be obstructed can't on move, make that point of connection is broken.
The utility model compared with prior art, but the bottle cap one-shot forming is simple in structure, is convenient to install, tooling cost is low, uses laborsaving convenience.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model front view
Fig. 2 is the utility model birds-eye view
In Fig. 1: (1) bottle cap; (2) point of connection; (3) single screw thread; (4) anti-back-off circle; (5) two screw threads.
The bottle cap material can be plastics, single injection-molded, and two screw threads and whorl of bottleneck are interference fit, firmly effect is better fast when uncapping, and anti-back-off circle is come off rapidly.
