Abstract

The utility model discloses a bottle cover capable of being opened and closed automatically. The bottle cover comprises a cover body which can be screwed on a bottle neck, wherein an annular ring at the top of the cover body is concave inwards, the middle part of the annular ring constitutes a spherical bulge positioned in the cover body, a very thin connecting edge is arranged at the joint of the edge of the spherical bulge and the cover body, an elastic sealing piece which is in close fit with the inner side surface of the spherical bulge and pressed on a bottle mouth by the cover body is adhered on the inner side surface of the spherical bulge, and one or more slits are formed on the edge of the elastic sealing piece, which corresponds to the joint at intervals. The integrated connection part of the spherical bulge and the cover body is very thin, the part can be disconnected, then the elastic sealing piece is further pressed for producing deformation, the slits on the elastic sealing piece can be opened, and liquid in a bottle can be sucked; and when the spherical bulge is released, the slits on the elastic sealing piece can be closed automatically for preventing the leakage of the liquid.

Description

A kind of bottle cap of automatic shutter

Technical field

The utility model relates to beverage bottle, is specifically related to the bottle cap for the automatic shutter on the beverage bottle.

Background technology

In existing technology, after beverage bottle cap is opened, if do not finish off, then lid must be covered, do not cover, its opening that opens wide also can cause for the second time and pollute, in addition, drinking bottle mouth is rough, too large, suck also inconvenience, and the bottle that does not close the lid, if overturned, the liquid in the bottle can flow out.

Summary of the invention

The purpose of this utility model is, for the defects of prior art, provides a kind of bottle cap of automatic shutter, but this bottle cap autoshutdown when not drinking.

The technical scheme that the utility model provides is as follows: a kind of bottle cap of automatic shutter, comprise the lid that can be spun on the bottleneck, one annular ring at the top of described lid inwardly concaves, position in the middle of the annular ring consists of a hemisphere jut that is positioned at lid, the edge of hemisphere jut is very thin connection side with the junction of lid body, the medial surface of hemisphere jut is stained with one and matches with its medial surface, and be pressed against elastic sealing strip on the bottleneck by lid, described elastic sealing strip has one or multi-channel designated port corresponding to interval on the edge of described junction.

In the bottle cap of above-mentioned automatic shutter, described designated port is the mouth of a river or the gas supplementing opening that can automatically open and close.

Advantage of the present utility model is as follows: when pressing hemisphere jut downwards, because the position that hemisphere jut is connected with the lid one is very thin, this position can disconnect, continue to press elastic sealing strip, it can produce distortion again, and the designated port on it is opened, can suck the liquid in the bottle, when unclamping hemisphere jut, but on the designated port automatic pressing on the elastic sealing strip, can prevent that liquid from spilling.

Fig. 3 is the schematic diagram of elastic sealing strip designated port shown in Figure 2 when opening.

The specific embodiment

With reference to Fig. 1, Fig. 2, shown in Figure 3, design a kind of bottle cap of automatic shutter, comprise the lid 1 that can be spun on the bottleneck, one annular ring at the top of described lid 1 inwardly concaves, position in the middle of the annular ring 102 consists of a hemisphere jut 101 that is positioned at lid, the edge of hemisphere jut 101 is very thin connection side 102 with the junction of lid 1 body, can in the 0.1-0.8 millimeter, select, the medial surface of hemisphere jut 101 is stained with one and matches with its medial surface shape, and be pressed against elastic sealing strip 2 on the bottleneck by lid 1, described elastic sealing strip 2 has one or multi-channel designated port 201 corresponding to interval on the edge of described junction.

In the bottle cap of above-mentioned automatic shutter, described designated port 201 is water outlet or the gas supplementing openings that can automatically open and close.When pressing hemisphere jut 101 downwards, the edge of hemisphere jut 101 and the position that lid 1 one is connected very thin (0.1-0.8 millimeter), this position can disconnect, continue to press again, can press elastic sealing strip 2 and produce distortion, designated port 201 is opened, can suck the liquid in the bottle, when unclamping hemisphere jut 3, but on designated port 201 automatic pressings on the elastic sealing strip 2, thereby prevent that liquid from spilling.

Claims

1. the bottle cap of an automatic shutter, comprise the lid that can be spun on the bottleneck, it is characterized in that: an annular ring at the top of described lid inwardly concaves, position in the middle of the annular ring consists of a hemisphere jut that is positioned at lid, the edge of hemisphere jut is very thin connection side with the junction of lid body, the medial surface of hemisphere jut is stained with one and matches with its medial surface, and be pressed against elastic sealing strip on the bottleneck by lid, described elastic sealing strip has one or multi-channel designated port corresponding to interval on the edge of described junction.

2. the bottle cap of automatic shutter according to claim 1, it is characterized in that: described designated port is water outlet or the gas supplementing opening that can automatically open and close.
