Problems solved by technology

[0003] However, judging from the top view of the currently manufactured bottle mouth (the bottle is placed in a normal state, and the bottle mouth is facing directly above), the beginning of the thread thread covers the end of the adjacent thread thread, that is to say, the two are overlapped and staggered together. , then the convex tooth screw inlet is narrow, and due to the limitation of the current processing accuracy of the bottle cap and the bottle mouth, sometimes it is difficult for the convex tooth to enter the convex tooth screw inlet, or it is too tight; it can be seen that the current market The threaded construction on the top of the bottle does not fit well with the tinplate cap

Embodiment

[0016] Embodiment: a kind of bottleneck that is convenient to bottle cap screwing in, as Figure 1-2 As shown, it includes a bottle mouth 1 and four inclined thread teeth 2 evenly arranged on the outer ring of the bottle mouth 1, each thread thread 2 includes a start 3 and an end 4, and the start 3 of any thread 2 is connected to the adjacent thread The ends 4 of the teeth 2 are staggered to leave a space 5 left and right.

[0017] Specifically, in the horizontal direction, the central angle of the arc corresponding to the left and right intervals is 17°. If this ratio is set, the guiding function of the inclined thread 2 is played, and the convex teeth can be more stably buckled on the thread. 2 below; the angle formed by the inclined threaded teeth 2 relative to the horizontal plane is 10°; the number of said threaded teeth 2 is 4, and each threaded tooth 2 is matched with a protruding tooth respectively, between the bottle cap and the bottle mouth 1 Very stable.

Abstract

The invention relates to an opening convenient to screw in a cap. The opening convenient to screw in the cap comprises an opening body, and a plurality of inclined threads that are uniformly formed in an outer cycle of the opening body; each thread comprises a starting end and a tail end; the starting end of any thread is staggered with the tail end of the adjacent thread in order to reserve left and right intervals. Compared with the prior art, the starting end of the thread is staggered with the tail end of the adjacent thread to form the left and right intervals, thus an screw-in opening of a convex tooth is expanded during screwing in, and as a result, the convex teeth can be conveniently screwed in, the cap can be matched well with the opening, both time and force are saved, and the convenience is brought.

Description

technical field [0001] The invention relates to the technical field of bottle mouth manufacturing, in particular to a bottle mouth which is convenient for screwing in a bottle cap. Background technique [0002] The tinplate cap currently on the market is generally matched with the glass bottle mouth. The commonly used tinplate cap will evenly set four convex teeth facing the center of the lid on the edge of the opening. Thread fit, each thread includes the beginning and the end, because the beginning is higher than the end, the thread is inclined, the thread is set to be inclined to guide the path of the convex tooth, the beginning here is the screwing of the convex tooth and the unscrewed part; specifically, the upper and lower gaps between the beginning of a thread and the end of the adjacent thread form a convex tooth screw inlet, and the convex teeth are screwed in from the convex tooth screw inlet so that the convex teeth buckle the thread teeth, The tinplate lid cover...
