CN2687043Y - Threaded bottleneck cap - Google Patents

Abstract

The utility model relates to a bottleneck press-cap with screw threads, comprising a bottleneck and a press-cap. The bottleneck press-cap with screw threads is characterized in that: the bottleneck is straight column shaped; the exterior of the top end of the bottleneck is provided with outer screw threads which are dextral screw threads or sinistrorse screw threads and are divided into three discontinuous sections, and the outer screw threads form an interlocking opening on the inner side of the press-cap; screw threads are formed on the interlocking opening, are inner screw threads, and are dextral screw threads, corresponding to the outer screw threads of the bottleneck, being divided into three discontinuous sections; after the press-cap and the bottleneck are in a press fit, as the screw threads are combined together in an interlocking mode, a sealing state is achieved; when the press-cap is rotated in the left direction, the bottle cap and the bottleneck are separated. The bottleneck press-cap with screw threads has the advantages that the structure is simple, the manufacturing is easy, the use is convenient, and the bottleneck can be opened by screwing the press-cap by hand in a rotary mode.

Description

A kind of threaded bottleneck gland

Technical field

The utility model relates to a kind of bottleneck bottle cap sealing improvement technology, is adapted at implementing on beer, the beverage bottle to use.

Background technology

At present, the beer of selling on the market and the glass bottle of some beverages all adopt the gland form, and bottleneck adopts no screw thread flat-top outer bottleneck, loam cake adopts the gland form, this kind bottleneck hermetically-sealed construction is simple, and it is also comparatively convenient produce to use, but its weak point is must use special tool when opening, Bottle opener, give daily edible making troubles, particularly travel on official business or, very inconvenience when having dinner in operation in the open air, adopt other method to open, often cause the damage of bottleneck or cause that accident takes place.

Summary of the invention

Open the inconvenience of using special tool for solving above bottleneck, the purpose of this utility model provides a kind of threaded bottleneck gland, utilizes the draw bail of the screw thread of bottleneck and loam cake, just can realize bottleneck uncap easy to use, without the purpose of special tool.

The structure design of the utility model is achieved in that

Threaded its structure of bottleneck gland of the utility model includes bottleneck and gland two parts are formed, it is characterized in that bottleneck adopts straight shape cylinder bottleneck, tip exterior at bottleneck is provided with outside thread, be right-hand screw thread, divide three periods discontinuous (as shown in Figure 1), at the inboard articulation port that forms of gland, on articulation port, form screw thread equally, be negative thread, corresponding with external thread of bottleneck, three sections of branches are discontinuous, are right-hand screw thread (as shown in Figure 2), after gland and the bottleneck pressing, because threaded engagement combines, reach sealing state, left-handed gland, bottle cap separates with bottleneck.

The utility model has following advantage compared with the prior art: simple in structure, make easy, very easy to use, turn gland with hand-screw and can open bottleneck.

Description of drawings

Fig. 1 is the bottle neck hitch composition of threaded bottleneck gland;

Fig. 2 is the gland structure figure of threaded bottleneck gland;

The specific embodiment

Its structure is as shown in drawings: 1 bottle, 2 bottlenecks, 3 outside threads, 4 glands, 5 articulation ports, 6 negative threads, with bottle cap after pressing on the bottleneck, bottle cap is connected with bottleneck,, form sealing state because threaded engagement is sealed, when needs are opened, with the hand-screw lid of screwing on, bottle cap just can screw out along hand of spiral, reach purpose of opening.

Claims (1)

1. threaded bottleneck gland, include bottleneck (2) and gland (4) two parts and form, it is characterized in that bottleneck (2) adopts straight shape cylinder bottleneck (2), be provided with outside thread (3) in the tip exterior of bottleneck (2), be right-hand screw thread or minus thread, divide three sections discontinuous; At the inboard articulation port (5) that forms of gland (4), go up at articulation port (5) equally and form screw thread, be negative thread (6), corresponding with bottleneck (2) outside thread (3), divide three sections discontinuous, be right-hand screw thread or minus thread; After gland (4) and bottleneck (2) pressing,, reach sealing state because threaded engagement combines.
