Abstract

The utility model relates to a bottle cap, which comprises an upper cap body and a lower cap body. The utility model is characterized in that the lower cap body is provided with a spherical surface bearing concave, the middle part of which is provided with an eyelet, and the inner part of the bearing concave is provided with a valve ball with a through hole; the valve ball is inversely buckled with the upper cap body with a spherical surface recess, and the upper cap body is provided with a flat notch which is communicated with the spherical surface recess; the upper end of a suction tube inserted into the through hole of the valve ball passes through the flat notch of the upper cap body, and the cap body is provided with internal threads used for that the cap body can be screwed with a bottle jack. When the utility model is used, the suction tube is pushed to the middle part by a finger, so that the through hole of the valve ball is aligned with the eyelet of the lower cap body; when the suction tube is pushed again, the utility model can be closed. The utility model has the advantages of simple structure and convenient and sanitary use.

Description

A kind of bottle cap

The utility model belongs to the small stores field, particularly a kind of bottle cap.

As everyone knows, the function of bottle cap is exactly the sealed against leakage effect.But for easy to use or other demand, bottle cap has developed into of all kinds, as mineral water bottle cap, monomer is arranged, also compound lid arranged.Compound lid comprises the lid and the protruding core body of disjunctor band side leakage eyelet with it, outside protruding core body, be arranged with top slip lid with holes, slip lid comes downwards to the bottom and promptly closes protruding core body side leakage eyelet, water can not flow out, and when slip lid is pulled to a high position, water can flow out in slip lid and from apical pore along the side leakage orifice flow, and slip lid also is equipped with a dustproof tegillum outward.This bottle cap need firmly pull up or depress slip lid when using, and slip lid water outlet just also is a suction nozzle, rises or depresses with hand-lifting and can bring suction nozzle to pollute, and is more unhygienic, must bimanualness during use, and drinking to special operating personnel makes troubles.

The purpose of this utility model is the bottle cap that a kind of one hand of design can be operated keying.

Task of the present utility model is achieved in that a kind of bottle cap, comprise upper cover body and lower cover, sphere holds recessed to it is characterized in that being provided with up by lower cover, hold recessed middle part and offer eyelet, hold the recessed built-in valve ball that is provided with a band through hole, the upper cover body of back-off one dribbling face recess on the valve ball, upper cover body offers a flat notch, notch connects through the upper cover body middle part and with the sphere recess, and the flat notch of upper cover body is passed in the suction pipe upper end that is plugged in the valve ball through hole, and lid is provided with the negative thread that spins with bottleneck.Lid is tightened on the bottle, during use, only needs singlehanded with pointing the pushing tow suction pipe to the middle part, suction pipe drive valve ball makes the eyelet on the through-hole alignment lower cover, and water can flow out through suction pipe by eyelet, when closing, also only need touch suction pipe, make valve ball turn over certain angle through hole and eyelet and stagger and get final product.

The utlity model has reasonable in design, easy to use, one hand can be operated, and sealing is reliable; Sheathed slide block outside suction pipe drives the valve ball keying by promoting slide block, avoids hand directly to touch suction pipe during operation, uses much cleaner.

Below in conjunction with concrete legend the utility model is described further:

Fig. 2 is Figure 1A-A generalized section

Fig. 3 is Bottle cap structure two generalized sections

Fig. 4 is Bottle cap structure three generalized sections

Embodiment one

With reference to Fig. 1 and Fig. 2, a kind of bottle cap, comprise upper cover body 1 and lower cover 2, wherein lower cover 2 is provided with up that sphere holds recessed 21, hold recessed 21 middle parts and offer eyelet 22, hold the recessed 2 built-in valve balls 3 that are provided with a band through hole 31, the upper cover body 1 of back-off one dribbling face recess 11 on the valve ball 3, upper cover body 1 offers a flat notch 12, notch 12 connects through upper cover body 1 middle part and with sphere recess 11, upper cover body 1 flat notch 12 is passed in suction pipe 32 upper ends that are plugged in the valve ball through hole 31, and lid is provided with the negative thread that spins with bottleneck.The negative thread of lid is meant the negative thread that is located on the lower cover 2, and upper cover body 1 fastens or is screwed in lower cover 2, and this legend is to adopt screw thread to be screwed in together, screws so also and can pin valve ball 3, and it can not be rotated, and slightly one loosens and gets final product.The flat notch 12 of upper cover body is along being provided with chute 13 one, and the slide block 33 that is set in suction pipe 32 upper ends is set on the chute 13 just, promotes slide block 33 and can drive suction pipe 32 rotations along chute 13, avoids finger to touch suction pipe 32, keeps the health of 32 mouthfuls in suction pipe.Suction pipe 32 is built-in with a band angle telescopic pipe 34, and suction pipe 32 ends are exposed in telescopic pipe 34 upper ends, can extract telescopic pipe 34 with mouth during use, play the lengthening effect, also conveniently suck.

In addition, use on the bottleneck of this structure bottle cap and can add the soft lid of sealing film, during use, suction pipe turns to lower cover eyelet place, presses down telescopic pipe, and the angle of telescopic pipe can puncture the soft lid of film.Embodiment two

With reference to Fig. 3, basic structure and embodiment are together, wherein the negative thread of lid is meant the negative thread that is located on the

upper cover body

1,2 one-tenth plugs of lower cover shape, outer convex edge 23 is folded between upper cover body 1 and the bottleneck locatees, and this structure lid is more compact, can be designed to upper cover body 1 equally when screwing, valve ball 3 can not rotate, and whole structure and example are together.

With reference to Fig. 4, the lower cover sphere holds the left and right sides on recessed 21 inherent valve ball through hole 31 path of motions and is provided with and incises 24, and the angle of telescopic pipe 34 can insert to be incised in 24, can further take in telescopic pipe 34 like this, the upper end flushes substantially with upper cover body 2 outside faces, offers convenience to packing.This structure is equally applicable to example one, is not describing in detail here.
