Abstract

The invention discloses a bottle cap capable of being opened and closed automatically, which comprises a cap body screwed on a bottle neck, wherein an integrally molded spherical bulge is arranged at the top of the cap body; the connection part between the edge of the spherical bulge and the cap body is indented downward to form an annular connection side; an elastic sealing strip fitted with the shape of the inner side face of the spherical bulge is adhered to the inner side face of the spherical bulge; the edge of the elastic sealing strip is pressed against a bottle mouth by the cap body; and one or more cuts are formed on the edge of the elastic sealing strip at intervals. The indented side of the spherical bulge, integratedly connected with the cap body, is very thin and can be broken when the spherical bulge is pressed downward, and the elastic sealing strip is pressed downward further to press the elastic sealing strip to deform; the cuts on the elastic sealing strip are opened, so that liquid in a bottle can be sucked; and when the spherical bulge is released, the cuts on the elastic sealing strip can be automatically closed under the elastic action so as to prevent the liquid from leakage.

Description

But the 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; It is characterized in that: integrated hemisphere jut is arranged at the top of said lid; The edge of hemisphere jut and the junction of lid are recessed downwards, constitute the connection side of an annular, are bonded with the elastic sealing strip that matches with its medial surface shape at the medial surface of said hemisphere jut; The edge of elastic sealing strip is pressed against on the bottleneck by 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, hemisphere jut and lid one bonded assembly indented edge are very thin, can break; Hemisphere jut can separate with lid, if press hemisphere jut downwards, then can press elastic sealing strip and produce distortion; Designated port on the elastic sealing strip is opened, and can suck the liquid in the bottle, when unclamping hemisphere jut; Designated port on the elastic sealing strip closes under elastomeric effect 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

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, integrated hemisphere jut 101 is arranged at the top of lid 1; The junction of the edge of hemisphere jut 101 and lid 1 is recessed downwards; Constitute the connection side 102 of an annular, connection side 102 is processed very thin structure, is bonded with the elastic sealing strip 2 that matches with its medial surface shape at the medial surface of said hemisphere jut 101; The edge of elastic sealing strip 2 is pressed against on the bottleneck by lid 1, has at interval together or multiple tracks designated port 201 on the edge of said elastic sealing strip 2.Designated port 201 is under the effect of external force, can open automatically, but after external force disappears the water outlet or the gas supplementing opening of SELF CL.

When pressing hemisphere jut 101 downwards, the edge of hemisphere jut 101 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 101, 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: integrated hemisphere jut is arranged at the top of said lid, and the edge of hemisphere jut and the junction of lid are recessed downwards; Constitute the connection side of an annular; Be bonded with the elastic sealing strip that matches with its medial surface shape at the medial surface of said hemisphere jut, the edge of elastic sealing strip is pressed against on the bottleneck by lid, has at interval together or the multiple tracks designated port on the edge of said elastic sealing strip.

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