Abstract
The utility model relates to a movable sealing part, in particular to a bottle cover. The bottle cover comprises a cover which is hinged on a cylinder body, the top of the cylinder body is connected with a damp block, a retaining ring is connected on the damp block. A sleeve is also arranged on the same medial axis in the cylinder body, an oblique convex part which is arranged on an inner wall of the cylinder body and an outer wall of the sleeve form an upper sealing square-cavity. The bottle cover has the beneficial effects: 1. the product no longer uses a metal cover to seal, thereby the cost is decreased, and the bottle cover no longer occurs the rust phenomenon. 2. the product no longer uses the bolt joint structure between the bottle cover and the bottle neck, but uses the fastening mode, thereby the product structure is simplified and the sealing performance is good.
Description
Technical field
The utility model relates to movable mouth piece, specifically belongs to a kind of 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, announce a denomination of invention as Patent Office of the People's Republic of China: improved bottle cap, application number is: 02110436.0, its structure is described to be: it has one to go up end closure, the uncovered cylindrical shell in lower end, also have cylindrical shell and both coaxial lines in the cylindrical shell, also there is weak point in described structure: do not back-out if bottle cap tightens on bottle or to the people, occur the seepage phenomenon easily, its sealing effectiveness is not good enough.
Also have some on the market in order to address the above problem, press seal is close on bottle earlier a tin-plate lid, is with plastic bottle closure more up, solves the seal leak phenomenon, but also has weak point: 1, the tin-plate lid is deposited a period of time and is got rusty easily; Need carry out extrusion process when 2, the tin-plate lid is installed, the bottle neck of crushing is easily installed inconvenience and the high shortcoming of productive costs.
The utility model content
The purpose of this utility model is to overcome the shortcoming that said structure exists, and the bottle cap that a kind of cost is low, easy for installation and leak tightness is strong is provided.
The utility model is realized with the following methods: comprise being articulated in cylinder top cover, cylinder top is connected with block, connect clasp on the block, on the same axis sleeve is set also in the cylindrical shell, oblique protuberance and sleeve outer wall are set on its described cylinder inboard wall constitute the back seal cavity volume.
Described back seal cavity volume communicates with cavity volume that cylindrical shell is set.
Also has spacing block set in the described sealed volume.
The beneficial effects of the utility model are: 1, this product no longer adopts crown cap to seal, thus cost-cutting, and make the bottle cap phenomenon of no longer getting rusty; 2, this product does not re-use the spiro connection structure between bottle cap and the bottle neck, and uses the snapping mode, simplifies product structure and good airproof performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.
As shown in the figure, comprise and be articulated in cylindrical shell 1 upper cover 2, cylindrical shell 1 top is connected with block 4, connect clasp 3 on the block 4, on the same axis sleeve 103 is set also in the cylindrical shell 1, oblique protuberance 105 is set on its described cylindrical shell 1 inwall constitutes back seal cavity volume 102 with sleeve 103 outer walls, oblique protuberance 105 is stuck in the bottleneck position, prevents that effectively bottle cap from getting loose.
Described back seal cavity volume 102 communicates with cylindrical shell 1 cavity volume of setting 101.
Also has spacing block set 104 in the described sealed volume 102.
The bottle neck of bottle is embedded in the sealed volume 102, and seals its bottle neck place, effectively prevents seepage.
