Abstract
The utility model discloses an opening and closing device for a container which is safe and convenient, comprising a thread mouth which is arranged at the outer surface of the bottle mouth and winded in a screwed type and a bottle cap which is matched with the thread mouth. The inner surface of the top end of the bottle is designed with a mastoid which is tightly fitted with a narrow tip end passage of the bottle mouth. Adopting the above structural design, the opening and closing device for the container makes the degree of the tight fit good, effectively solving the defect that the sealed passage of the original technical bottle mouth being cut away through the scissors is not sanitary and convenient.
Description
Technical field
The utility model relates to a kind of closing device of container, especially a kind of structural development of container closing device of interior storage liquid.
Background technology
The container of existing medical interior storage liquid, as the eyedrops plastic bottle, its bottleneck adopts hermetically-sealed construction, and when people used, needing to cut off the bottleneck sealed end with scissors could use, and so both unhygienic, complicated operation seems again; People also idea seal with the form of bottle cap inner face cushioning seal ring, but because the eyedrops one-shot usage needs one, and dosage is very little, and this bottleneck is relatively large, the use that uncomfortable easily patient's eyedrops instils.
Summary of the invention
At the technical matters of above existence, the utility model proposes a kind of safe and convenient container closing device.
The technical solution of the utility model is achieved in that a kind of container closing device, comprise and place bottleneck outside face spiral to twine the line mouth, reach the bottle cap that matches with its line mouth, described bottle cap top inner face designs a mastoid process, with narrow and small bottleneck tip channel driving fit mutually.
During use, open bottle cap, the extruding body, the bottle content oozes out by the bottleneck tip channel, and not the time spent, the bottle cap that closes is tightened by the line mouth of bottleneck outside face, makes the mastoid process of bottle cap top inner face insert the bottleneck tip channel, and driving fit with it.
Because the utility model has adopted above technical pattern feature,, solved original technology bottleneck effectively and opened unhygienic, inconvenient defective so closed intensity is very good.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is that front view cuts open in the office of an embodiment of the utility model.
Among the figure: 1, bottleneck 11, line mouth 12, passage 2, bottle cap 21, mastoid process
The specific embodiment
As shown in drawings, a kind of container closing device, material therefor is plastics, comprises placing bottleneck 1 outside face spiral to twine line mouth 11, reaches the bottle cap 1 that matches with its line mouth 11, bottleneck 1 tip is provided with passage 12, bottle cap 2 top inner faces design a mastoid process 21, and when closing bottle cap 2, bottle cap 2 is tightened by the line mouth 11 of bottleneck 1 outside face, make the mastoid process 21 of bottle cap 2 top inner faces insert bottleneck 1 tip channel 12, and driving fit with it.
Claims (2)
