CN2934117Y - Suction thin plastic bottle cap - Google Patents

Abstract

The utility model is a plastic bottle cap which can control the water flow size freely. The utility model is divided into an outer cover and an inner cover. An ellipse suction mouth hole is arranged on the upper side of the inner cover. The lower end plastic hole (4) is communicated with the plastic hole (5). The upper end of the inner cover is contacted with the outer cover, and the lower end is contacted with the bottle body. When people drink, the water is drunk from the suction mouth hole, at the same time air enters from the plastic hole (4), and pushes away the plastic ball and goes into the bottle from the plastic hole (5), the water sucked is controlled as the same volume as the air enters, thus water flow size can be controlled freely.

Description

Inhale thin plastic bottle closure

Affiliated technical field

The utility model relates to a kind of bottle cap of the usefulness of drinking water, especially the plastic bottle closure of free control water size.

Background technology

At present, known plastic bottle closure has only enclosing cover, is that the enclosing cover body is screwed in together.When drinking water, water flows out along with the height of bottle, suddenly big or suddenly small water.But, when many people drink water, can not suitably control the size of water.General plastic bottle is not controlled the plastic device of water size, cause like this drink water uncomfortable.

Summary of the invention

Suddenly big or suddenly small when drinking water in order to overcome general plastic bottle, this utility model is a kind of plastic bottle closure, and this plastic bottle closure not only suction nozzle is oval, is fit to people's degree of lip-rounding, and the size of energy free control water.

It is that practical technical scheme is that the utility model solves its technical matters: in be stamped the suction nozzle hole, plastic eyelet (4), plastic eyelet (5) baton round, when the people is drinking water from suction nozzle the water absorbing while, air enters and opens baton round from plastic eyelet (4), enters in the bottle from plastic eyelet (5), and baton round returns original position when not absorbing water, SELF CL reaches the purpose of freely drinking water.

The utility model beneficial effect is: the oval degree of lip-rounding that is fit to the people of suction nozzle, and size that can free control water, only many inner caps are simple in structure.

Description of drawings

Below in conjunction with accompanying drawing utility model is further specified

Fig. 3 is side midship section figure

Fig. 4 is the center section-drawing

Controlling point (1) in the drawings. oval suction nozzle (2). inhale hole (3). plastic eyelet (4). plastic eyelet (5). baton round (6). sticking plaster (7). enclosing cover (8).

The specific embodiment

In Fig. 1, controlling point (1) is to prevent that inner cap from falling in the bottle.

In Fig. 2, in order to guarantee the size of free control water, suction hole (3) is 2 times of plastic eyelet (4), and plastic eyelet (4) is 2 times of plastic eyelet (5), and sticking plaster (7) makes baton round keep certain activity space.

Claims (1)

1, the thin plastic bottle closure of a kind of suction divides exterior and interior cover, enclosing cover is a dome, oval suction nozzle hole is arranged in inner cap, plastic eyelet (4), baton round, plastic eyelet (5), it is characterized in that: suction nozzle hole, inner cap upper end contacts with outer caping is interior, and the inner cap upper end is oval and has suction nozzle hole, lower end that baton round and plastic eyelet (5) are arranged, plastic eyelet (4) is communicated with, and the inner cap lower end is connected with body.
