Abstract
The utility model discloses a plastic bottle provided with a sealing device and a circular groove. The plastic bottle comprises a bottle body, an outer cap and an inner cap, wherein the circular groove is formed in the outer side of the neck of the bottle body; the outer cap is in threaded connection with a bottle opening, the inner cap is located below the outer cap and nested at the bottle opening, a seal ring made of a flexible material is arranged between the inner cap and the bottle opening and pressed at the top of the bottle opening or the inner side wall of the bottle opening after clamped with the lower part of the inner cap; and a one-way vent valve is arranged on the inner cap. The plastic bottle has a good sealing effect, the inner air pressure and the outer air pressure of the plastic bottle provided with the circular groove can be balanced, and the bottle explosion problem due to increasing of the air pressure of the bottle body can be prevented.
Description
Technical field
The utility model relates to a kind of annular groove plastic bottle, is specifically provided with the annular groove plastic bottle of sealing arrangement.
Background technology
Annular groove plastic bottle is mainly a kind of food container, and the quality of its sealing property directly affects effective period of food quality.The annular groove of plastic bottle neck setting is used for holding water and is used for sealing bottleneck; but often can run into some users forgets and in annular groove, adds water; or due to other reason; water in annular groove does not reach a certain amount of and out of reach obturation effect; cause the food spoilage in plastic bottle, how further annular groove plastic bottle raising sealing property is the current technical issues that need to address.
Summary of the invention
The technical solution of the utility model is such, and a kind of annular groove plastic bottle with sealing arrangement, comprises bottle, enclosing cover, inner cap, described bottle neck outside is provided with annular groove, the enclosing cover bottleneck that is threaded, inner cap is socketed bottleneck below enclosing cover, between described inner cap and bottleneck, is provided with sealing member.
As optimal way of the present utility model, the seal ring that described sealing member is flexible material, it is pressed on bottleneck top and/or bottleneck madial wall after engaging with inner cap bottom.
As optimal way of the present utility model, cover in described and be provided with one-way exhaust valve.
As optimal way of the present utility model, the bottom of described inner cap outer rim is provided with one for the annular groove of sealing member is installed, and sealing member is fastened in the annular groove of inner cap, seals bottleneck sidewall during inner cap socket bottleneck.
As optimal way of the present utility model, described inner cap outward flange has a downward ring buckle limit, ring buckle limit locking bottleneck outside when inner cap and bottleneck socket.
As optimal way of the present utility model, described inner cap top inner side is provided with some horizontal flanges.
The utility model compared with prior art, arranges sealing member at bottleneck top and/or sidewall, leak tightness better effects if; Interior covering, one-way exhaust valve is set, energy balance annular groove plastic bottle inner and outer air pressure, when food fermentation causes gas expansion, one-way exhaust valve can outwards be got rid of gas in bottle, prevents from, because bottle internal gas pressure raises, the problem of fried bottle occurs; Interior covering, annular snap close is set, inner cap is combined more firm with bottleneck; Interior covering, lateral flange is set, conveniently takes off inner cap.
