Abstract

The utility model relates to a bottle cap which has no such phenomenon that when every time the liquid in the bottle is poured, small amount of liquid which is attached to a bottle mouth flows downwards along the outer side of the bottle mouth happens. The utility model is composed of a cap body and a cap cover. A double-lip structure is arranged on the upper part of the cap body, and the bottom part of the U-shaped body groove of the cap body has a flow returning hole which is communicated with the inner cavity of the inner lip of the cap body. A baffle plate and a sealing film are respectively arranged in the inner cavity of the inner lip of the cap body, and the cap cover is provided with a double-lip structure which is matched with the double-lip structure on the cap body. When used, small amount of liquid attached to the inner lip flows downwards to the bottom part of the U-shaped groove on the cap body, and the liquid flows back to the bottom through a flow returning hole.

Description

Bottle cap

The utility model relates to a kind of bottle cap, particularly relate to a kind of can be whenever not falling liquid in the single-trip container, just have a small amount of dirty along the bottleneck lateral attached to the liquid of bottleneck, thereby keep the bottle cap of bottle cleaning.

Since flask occurring, no matter be that bottleneck directly is produced on the body, still the bottle cap by pipeline is arranged is as bottleneck, in use all there is a common problem, promptly whenever pour out the liquid in the single-trip container, just have a small amount of dirty along the bottleneck lateral attached to the liquid of bottleneck, polluted bottleneck, the place of body and placement bottle and user's hand, for edible liquid, also can be infected breeding by harmful bacteria owing to bottleneck is exposed to exterior liquid, pollute the liquid in the bottle, make the rotten rapidly corruption of liquid in the bottle, produce waste, be detrimental to health, even cause food poisoning.Therefore, existing flask bottle mouth position liquid is along the defluent defective in the bottleneck outside, the worry of having brought for people's work and life to use and clean and to the harm of health.

The purpose of this utility model just provides a kind of bottle cap, it can not only play the effect of existing bottle cap, and it is dirty along the bottleneck lateral in use not have liquid, thereby the clean health that keeps bottle, eliminated often clean, to the pollution of environment, and, improve quality of life and health level to the worry that the infection of liquid in the bottle brings.

The purpose of this utility model be achieved in that bottle cap by lid and the block two parts form, screw or bayonet socket and the hermetically-sealed construction that connects with bottleneck arranged at the bottom of lid, the lips mouth structure that is made of lid outer lip and lid inner lip is arranged on the top of lid, the return port that communicates with the inner chamber of inner lip is arranged at the bottom of the U-lag between the lips mouth, baffle plate and sealing film are arranged in the inner chamber of lid inner lip, the lips mouth structure that cooperates with the lips mouth structure of lid is arranged on the block, whenever finish the action of once pouring out liquid in the bottle, on a small quantity attached to the liquid at lid inner lip top along flowing to U-lag under its lateral, along the U-lag bottom, the return port that communicates with the inner lip inner chamber of flowing through enters in the bottle, and liquid is not accumulated in U-lag.Because the liquid lid outer lip of not flowing through, it is dirty and pollute along the bottle lateral not have liquid naturally.The lid inner lip cooperates with the block inner lip.In the use, the lid inner lip has the inboard that micro liquid is stained with the block inner lip, and the inboard of edge block inner lip splashes in the U-lag of lid.The block outer lip cooperates with the lid outer lip, the auxiliary section both but screw thread, also but bayonet socket, play the effect of seal isolation bottle internal and external environment.Like this, bottle cap is just in the time spent of doing of playing general bottle cap, behind pouring liquid, do not have liquid along bottleneck, bottle cap, body to dirty.

The height that the lid U-lag has return port one side bottom is less than or equal to the height of bottom of the U-lag of a relative side, and the liquid that helps flowing into the U-lag bottom so all flows in the bottle by return port rapidly.As the height that makes the lid U-lag have the return port side bottom is lower than the bottom of a relative side U-lag, even it is out-of-level to place the position of bottle, the liquid in the U-lag flowed in the bottle.

Baffle plate is in the return port side, is lower than or contour with the return port bottom, and sealing film is lower than or is contour with the return port bottom, and draw ring is arranged on it.During pouring liquid, should make return port up, avoid liquid to flow on the lid outer lip from return port.Baffle plate makes and produce throttling action when toppling over rapidly, and liquid is flowed out from return port.The sealing film of inner lip inner chamber is kept apart liquid in the bottle and external environment, is used for manufacturer's sealed inside liquid when factory state, during use, spurs the draw ring on the sealing film, sealing film is pulled off get final product.

Owing to adopt such scheme, can make that in use not have liquid dirty along the lateral of bottle, eliminated back to dirty attached to the liquid of bottleneck in the past in each use, pollute the use that bottle, the place of putting bottle, user's hand etc. brings, the worry of cleaning, and the bacterial contamination waste that bottle interior liquid gone bad bring and to the harm of health.Its structure is very simple, and productive costs is low.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a cutaway view of the present utility model.

Among Fig. 1, the long and two-short dash line situation on lid of representing to block a shot.During use, screw thread or bayonet socket and the hermetically-sealed construction (1) of bottle cap by lid (2) bottom is connected as one with bottle, have by lid outer lip (3) on lid (2) top, lid U-lag (4) structure that lid inner lip (5) constitutes, with the bottom of the lid U-lag (4) of connector (10) homonymy of bottle cap the return port (9) that communicates with the inner chamber of lid inner lip (5) is being arranged, in return port (9) side, be lower than or a baffle plate (8) arranged with the end equal-height position of return port (9), be lower than or the sealing film (6) of seal isolation lid inner lip (5) inner chamber arranged with return port (9) end equal-height position, draw ring (7) is arranged on the sealing film (6), when using for the first time, pulling draw ring (7) pulls off sealing film (6) and just makes bottle cap form the passage of flow of liquid.Connector (10) couples together lid (2) and block (13), conveniently uses, avoids losing.Block outer lip (11) cooperates with lid outer lip (3) and plays sealing, isolate the effect of bottle internal and external environment, the block inner lip (12) internal diameter greater than the external diameter of lid inner lip (5) less than the internal diameter of lid outer lip (3), block outer lip (11) can not touch lid inner lip (5), block outer lip (5) forms block U-lag (14) with block inner lip (6), block inner lip (12) drops onto downwards in the lid U-lag (4) along its inboard with the liquid that lid inner lip (5) adheres to after touching, and block (13) is gone up to be had a projection (15) to make with connector (10) opposite side to be convenient to open block a shot (13).
