Abstract

The utility model relates to a bottle mouth structure provided with inner threads and mainly aims at providing a structure which is strong in sealing performance and simple in structure. The bottle mouth structure provided with the inner threads comprises a cylindrical bottle body in which a cavity is formed, and the upper end of the bottle body is provided with a bottle mouth which is connected with a bottleneck. The bottle mouth structure provided with the inner threads is characterized in that the inner wall of the bottle mouth is provided with the inner threads which are forward threads, and the outer circumferential face of the bottle mouth is provided with outer threads.

Description

A kind of bottleneck structure that is shaped with negative thread
Technical field
The utility model relates to a kind of bottleneck structure, the reeded bottleneck structure of specifically a kind of inwall system.
Background technology
Usually people come the store various types article with bottle, comprise liquid, gas shape and granular article; Usually adopt glass to make bottle, and adopt externally threaded connection structure at the outer circumference surface at bottle bottleneck position.But the outside thread connection structure making of the bottle cap that matches is with it had relatively high expectations, and sealing property also is difficult to further raising.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of improvement of bottleneck seal structure is provided, and this structure should have leak tightness characteristics strong and simple in structure.
The technical scheme that the utility model provides is:
A kind of bottleneck structure that is shaped with negative thread comprises that an inside is shaped with the cylindrical bottle of cavity, and the bottle upper end is the bottleneck that links to each other by bottleneck, it is characterized in that: be shaped with negative thread on the inwall of described bottleneck.
Described negative thread is the forward screw thread.
Also be shaped with outside thread on the outer circumference surface of described bottleneck.
The beneficial effects of the utility model are: owing to be shaped with negative thread on the bottleneck inwall in the utility model, therefore after using the bottle cap capping that is complementary with it, sealing effectiveness further improves than common bottle.If the outer circumference surface of bottleneck is mixed outside thread again, sealing property then is improved largely.
Description of drawings
Fig. 1 is the structural representation of one of the utility model embodiment.
Fig. 2 is two the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
Among the embodiment one shown in Figure 1, the inside of cylindrical bottle 1 is shaped with cavity, thereby can be used as container and hold article; The bottle upper end is the bottleneck 2 that links to each other by bottleneck, is shaped with negative thread 3 on the inwall of described bottleneck; Accordingly, should have a bottle cap to match with described bottleneck, this bottle cap be shaped with described bottleneck inwall on the outside thread that is complementary of negative thread.
Further, described negative thread preferentially adopts forward screw thread (being right-hand screw thread), to meet people's use habit.Special bottle also can consider to use reverse thread (being minus thread).
Among the embodiment two shown in Figure 2, except the inwall at bottleneck is shaped with the negative thread, also on the outer circumference surface of bottleneck, also be shaped with outside thread 5; Because having negative thread screws the dual structure that screws with outside thread, sealing property has obtained increasing exponentially.

Claims (3)

1. a bottleneck structure that is shaped with negative thread comprises that an inside is shaped with the cylindrical bottle (1) of cavity, and bottle upper end is the bottleneck (2) that links to each other by bottleneck, it is characterized in that being shaped with negative thread (3) on the inwall of described bottle body and bottleneck.
2. a kind of bottleneck structure that is shaped with negative thread according to claim 1 is characterized in that described negative thread is the forward screw thread.
3. a kind of bottleneck structure that is shaped with negative thread according to claim 2 is characterized in that also being shaped with outside thread (5) on the outer circumference surface of described bottleneck.
