Abstract

The utility model discloses a non-return ring of a bottle neck, which is composed of a bottle mouth, a bottle cover, and a non-return ring. The non-return ring is in a wolf teeth shape, the father teeth are arranged at the bottom part of screw threads at the bottle mouth, and the mother teeth are arranged at the lower edge of the bottom cover. Because the utility model adopts the wolf teeth shape or a round hole bevel shape, when the bottle cover is screwed at the bottle mouth, the non-return ring can be directly screwed and have a self-locking, and thus, once pouring and bottle sealing is completed; the technology link is decreased, and a secondary pollution is avoided.

Description

The bottleneck Non-return ring

The utility model belongs to a kind of bottleneck Non-return ring.

The bottle of neck part band Non-return ring is very common, but these Non-return rings all are rectangular teeth mostly, can not be with the direct precession self-locking of bottle cap, and this just makes also needs thermoplastic once to increase process procedure after filling bottle again, and liquid in the possible pollution bottle.

The purpose of this utility model is: provide a kind of bottleneck Non-return ring that can directly screw in, to overcome the problems referred to above.

The utility model is to constitute like this: it is by bottleneck (1), bottle cap (2), and Non-return ring (3) is formed, and Non-return ring (3) is a ratchet-shaped, and its public tooth is located at the bottom of thread of bottleneck (1), and female tooth is located at the lower edge of bottle cap (2).

Non-return ring (3) also can be the circular hole beveled, and its female tooth is located at the bottom of thread of bottleneck (1), and public tooth is located at the lower edge of bottle cap (2).

The utility model compared with prior art owing to adopted ratchet-shaped or circular hole beveled, makes bottle cap Non-return ring when screwing in bottleneck can directly screw in self-locking, thereby once finishes can envelope bottle, reduces process procedure, avoids secondary pollution.

Accompanying drawing 1 is the scheme drawing of the utility model ratchet-shaped Non-return ring;

Accompanying drawing 2 is ratchet-shaped Non-return ring profile of tooth figure;

Accompanying drawing 3 is the scheme drawing of the utility model circular hole beveled Non-return ring;

Accompanying drawing 4 is circular hole beveled Non-return ring profile of tooth figure.

Embodiment of the present utility model: the public tooth of the ratchet-shaped of Non-return ring (3) (or the female tooth of circular hole beveled) is directly injection-moulded in the bottom of thread of bottleneck (1), its female tooth (or the public tooth of circular hole beveled) is injection-moulded in the lower edge of bottle cap (2).

Claims

1, a kind of bottleneck Non-return ring, it is by bottleneck (1), bottle cap (2), Non-return ring (3) is formed, and it is characterized in that: Non-return ring (3) is ratchet-shaped, and its public tooth is located at the bottom of thread of bottleneck (1), and female tooth is located at the lower edge of bottle cap (2).

2, according to the described bottleneck Non-return ring of claim 1, it is characterized in that: Non-return ring (3) also can be the circular hole beveled, and its female tooth is located at the bottom of thread of bottleneck (1), and public tooth is located at the lower edge of bottle cap (2).
