Abstract

The invention discloses a bottle cap capable of being opened and closed automatically. The bottle cap comprises a cap body which can be screwed on a bottle neck, as well as an elastic sealing piece which is pressed on a bottle mouth by the top of the cap body, wherein a hole is formed at the top of the cap body, a spherical bulge extends out of the hole, the edge of the spherical bulge is pressed on the edge of the elastic sealing piece by an opening on the inner side of the cap body, and one or more cuts are formed on the edge of the elastic sealing piece at intervals; and when the spherical bulge is pressed down, the edge of the spherical bulge can press the elastic sealing piece to produce deformation, the cuts are opened, then liquid in a bottle can be sucked, and when the spherical bulge is released, the cuts on the sealing piece can be closed automatically and the leakage of the liquid can be prevented.

Description

But a kind of bottle cap of automatic shutter

Technical field

The present invention relates to beverage bottle, but be specifically related to be used for the bottle cap of the automatic shutter on the beverage bottle.

Background technology

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

Summary of the invention

The objective of the invention is to,, but a kind of bottle cap of automatic shutter is provided to the above-mentioned defective of prior art, but this bottle cap SELF CL when not drinking.

Technical scheme provided by the invention is following: but a kind of bottle cap of automatic shutter is provided; Comprise the lid that can be spun on the bottleneck; Comprise that also one is pressed against the elastic sealing strip on the bottleneck by said lid top, have a hole at the top of said lid, from the hole, be extended with a hemisphere jut; The edge of hemisphere jut is pressed against on the edge of said elastic sealing strip by the inboard opening of lid, has at interval together or the multiple tracks designated port on the edge of said elastic sealing strip.

But in the bottle cap of above-mentioned automatic shutter, said designated port is the water outlet or the gas supplementing opening that can open and close automatically.

Advantage of the present invention is following: when pressing hemisphere jut downwards, the edge of hemisphere jut can press elastic sealing strip and produce distortion, and designated port is opened; Can suck the liquid in the bottle; When unclamping hemisphere jut, the designated port on the seal strip closes automatically, can prevent that liquid from spilling.

Description of drawings

Fig. 1 is a structure cutaway view of the present invention;

Fig. 2 is an elastic sealing strip structural representation among the present invention;

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

The specific embodiment

Embodiment 1; With reference to Fig. 1, Fig. 2, shown in Figure 3; But a kind of bottle cap of automatic shutter is provided, comprises the lid 1 that can be spun on the bottleneck, comprise that also one is pressed against the elastic sealing strip 2 on the bottleneck by said lid 1 top; Have a hole 101 at the top of said lid 1; From hole 101, be extended with a hemisphere jut 3, the edge of hemisphere jut 3 is pressed against on the edge of said elastic sealing strip 3 by lid 1 inboard opening, has at interval together or multiple tracks designated port 301 on the edge of said elastic sealing strip 3.

But in the bottle cap of above-mentioned automatic shutter, said designated port 301 is to open automatically under external force, but after external force disappears the water outlet or the gas supplementing opening of SELF CL.

When pressing hemisphere jut 3 downwards, the edge of hemisphere jut 3 can press elastic sealing strip 2 and produce distortion, and designated port 201 is opened; Can suck the liquid in the bottle; When unclamping hemisphere jut 3, the designated port 201 on the elastic sealing strip 2 can close automatically, thereby prevents that liquid from spilling.

Claims

1. but the bottle cap of an automatic shutter; Comprise the lid that can be spun on the bottleneck; It is characterized in that: comprise that also one is pressed against the elastic sealing strip on the bottleneck by said lid top, have a hole at the top of said lid, from the hole, be extended with a hemisphere jut; The edge of hemisphere jut is pressed against on the edge of said elastic sealing strip by the inboard opening of lid, has at interval together or the multiple tracks designated port on the edge of said elastic sealing strip.

2. bottle cap according to claim 1 is characterized in that: said designated port is the water outlet or the gas supplementing opening that can open and close automatically.
