Abstract

The utility model relates to an automatic type bottle cap. The automatic type bottle cap is characterized by consisting of a bottle cap body and a steel ball. The steel ball in use is respectively located at the lower side and the upper side of a central groove of the bottle cap body by utilizing gravity per se when the bottle body stands or inclines so as to correspondingly close and open a channel. Therefore, an automatic closing and opening function of the bottle cap on the bottle body is realized.

Description

Self acting bottle cap

Technical field

The utility model relates to a kind of bottle cap, the bottle cap that especially can automatically open and seal.

Background technology

Bottle cap is in the market taking rotary open type and sealing band lifting type as main., there is the problem such as inconvenience, the easy loss of bottle cap that uses in wherein comparatively tradition of rotary open type.Sealing band lifting type occuping market gradually, but also sealing band effort and inconvenient is opened in existence, when use, the shortcomings such as the easy closure automatically of bottle cap upper cover.In view of this, be necessary existing bottle cap to be improved, to address the above problem.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and can automatically open and sealing and the bottle cap grown service life.

For realizing above-mentioned utility model object, the utility model provides a kind of bottle cap, and it comprises bottle cap body and steel ball.Described steel ball can move up and down under self gravitation effect in the central channel of bottle cap body inside.Described bottle cap body is containing central channel, passage, tap hole and centre hole, wherein central channel slightly larger in diameter in diameter of the steel ball so that steel ball can move therein, passage and tap hole flow out used for liquid, the effect of centre hole is to maintain the upper and lower air pressure balance of steel ball, can make again the liquid that infiltrates central channel flow out bottle cap.In addition, tap hole and centre hole are all positioned at the top of bottle cap body.

The beneficial effects of the utility model are: bottle cap of the present utility model is in the time that bottle vertically leaves standstill, and steel ball seals passage below central channel, i.e. self-closed bottle.And in the time of the oblique lower pouring liquid of bottle, steel ball moves along central channel toward centre hole direction under self gravitation effect, passage is opened automatically, and liquid runs down passage flows out through tap hole, has realized the automatic unlatching of bottle cap.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

As shown in Figure 1, bottle cap of the present utility model is enclosed within bottle top.As Fig. 2, bottle is in vertical static condition, and steel ball 1 relies on self gravitation below the central channel 4 of bottle cap body 2, automatically to seal the passage 3 of bottle cap body 2, and bottle cap is to bottle self-closed.

As shown in Figure 3, oblique the having a down dip of bottle that the utility model overlaps, now, steel ball 1 central channel 4 along bottle cap body 2 under self gravitation effect moves to the uppermost centre hole 5 of bottle cap body, passage 3 is opened automatically, now liquid can flow out through tap hole 6 along passage 3, has realized the automatic open function of bottle cap.

In an embodiment, the effect of the uppermost centre hole 5 of bottle cap body is to maintain the upper and lower air pressure balance of steel ball 1 to ensure its movement in central channel 4, and the liquid that can also make to infiltrate in central channel 4 flows out bottle cap simultaneously.

Claims

1. a self acting bottle cap, comprises bottle cap body and steel ball, it is characterized in that: described bottle cap body is containing central channel, passage, tap hole and centre hole; Described steel ball moves up and down in the central channel of bottle cap body.

2. self acting bottle cap according to claim 1, is characterized in that: steel ball can utilize self gravitation, in the time that bottle leaves standstill, seals passage, i.e. self-closed bottle below being positioned at central channel.

3. self acting bottle cap according to claim 1, it is characterized in that: steel ball can utilize self gravitation, bottle is oblique while having a down dip, automatically move to the uppermost centre hole direction of bottle cap body along central channel, open channel, can flow out through passage and tap hole liquid.
