Abstract
The utility model relates to a movable sealing piece, in particular to an improved bottle stopper, which has two coaxial canister bodies(1),(2). The canister body(2) is positioned in the canister body(1); the upper end of the canister body(1) is closed and the lower end is opened. After adopting the structure, the bottle stopper has two coaxial canister bodies(1),(2) and the canister body(2) is positioned in the canister body(1), so the canister body(2) with smaller radial size in the bottle stopper is air tightly matched with the inner wall or the outer wall of the bottle neck so that the bottle neck can be restricted by the canister body(1) with bigger radial size in the bottle stopper; in such way, when the radial size of the canister body(1) in the bottle stopper is bigger, the radial size of the bottle neck does not need to be enlarged at the same time, but just needs to be jointed with the canister body(2) with smaller radial size in the bottle stopper so as to reduce the production cost of the whole bottle and improve the economic benefit of the manufacturer on a certain extent.
Description
Technical field
The utility model relates to movable mouth piece, particularly relates to a kind of improved bottle cap.
Background technology
Existing bottle cap is generally end closure, the lower end is uncovered and interior threaded cylindrical tube.During use, the outer wall of this bottle cap and container neck is sealed and matched.Because this bottle cap engages with the neck of container, so that container neck certainly will be subjected to the restriction of bottle cap, when the radial dimension of this bottle cap greatly the time, the radial dimension of container neck just need be enlarged synchronously like this, make the manufacturing cost of entire container increase, had a strong impact on the economic benefit of manufacturer.
The utility model content
The purpose of this utility model is to provide a kind of improved bottle cap that can effectively reduce the container manufacturing cost.
For achieving the above object, this improved bottle cap has cylindrical shell (1), (2) of two coaxial lines, and cylindrical shell (2) is positioned at cylindrical shell (1), and last end closure, the lower end of cylindrical shell (1) are uncovered.
Cylindrical shell (1) is a cylindrical tube, and there is boss (1b) at the middle part of this cylindrical shell upper end outside face (1a).
Cylindrical shell (2) is a cylindrical tube, is shaped on screw thread and the cylindrical shell height height less than cylindrical shell (1) in this cylindrical shell.
After adopting such structure, because this bottle cap has the cylindrical shell (1) of two coaxial lines, (2), cylindrical shell (2) is positioned at cylindrical shell (1), during use, the less cylindrical shell (2) of radial dimension is sealed and matched with the inwall or the outer wall of container neck in this bottle cap, so that container neck can not be subjected to the restriction of the cylindrical shell that radial dimension is bigger in this bottle cap (1), like this when the radial dimension of this bottle cap middle cylinder body (1) is big, the radial dimension of container neck also need not to be enlarged synchronously, only need to engage and get final product with the less cylindrical shell (2) of radial dimension in this bottle cap, thereby effectively reduce the manufacturing cost of entire container, improved the economic benefit of manufacturer to a certain extent.
Description of drawings
Accompanying drawing is the semisectional view of the utility model most preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and most preferred embodiment the utility model is described in further detail:
Referring to accompanying drawing, this bottle cap has cylindrical tube (1), (2) of two coaxial lines, cylindrical shell (2) is positioned at cylindrical shell (1), last end closure, the lower end of cylindrical shell (1) are uncovered, there is cylindrical boss (1b) at the middle part of cylindrical shell (1) upper end outside face (1a), is shaped on the screw thread that can match with the container neck outer wall and the cylindrical shell height height less than cylindrical shell (1) in the cylindrical shell (2).
This bottle cap can adopt Shooting Technique Integratively formed.The storing material or the transfer cask of equipped this bottle cap can be widely used in the industries such as agricultural, food, medicine, chemical industry.
Certainly, cylindrical boss (1b) also can be with in the middle part of cylindrical shell (1) upper end outside face (1a), also can be made into the spiral shell rib of interruption in the cylindrical shell (2), and the height of cylindrical shell (2) can be equal to or greater than the height of cylindrical shell (1); In addition, also can not establish screw thread (at this moment, cylindrical shell (2) cooperates with the inner wall sealing of container neck) in the cylindrical shell (2).Equally, the section form of cylindrical shell (1), (2) also can be ellipse, square, rhombus or other suitable shapes; The section form of cylindrical shell (1), (2) also can be different, and promptly both section forms can combination in any.Above conversion all drops within the protection domain of the present utility model.
Claims (3)
1, improved bottle cap, it has one to go up end closure, the uncovered cylindrical shell (1) in lower end, it is characterized in that: also have cylindrical shell (2) and both coaxial lines in the cylindrical shell (1).
2, improved bottle cap according to claim 1 is characterized in that: cylindrical shell (1) is a cylindrical tube, and there is boss (1b) at the middle part of this cylindrical shell upper end outside face (1a).
3, improved bottle cap according to claim 1 and 2 is characterized in that: cylindrical shell (2) is a cylindrical tube, is shaped on screw thread and the cylindrical shell height height less than cylindrical shell (1) in this cylindrical shell.
