Background technology

Lid is the parts that nearly all container all has, and the effect that it plays mainly is to prevent that liquid in container from flowing out, and the packing technique of this respect is quite ripe at present.Development along with technology, people have had higher requirement to lid again, good sealing property should be arranged, can inject liquid easily again, also will have the runner of independence, health that liquid is flowed out simultaneously, for satisfying these requirements, common way is to adopt dual lid, promptly small lid of otherwise designed on big lid communicates with container.Big lid and small lid all adopt seal means, make the unlikely outflow of liquid in container, then open big lid when needing to inject liquid, then open small lid when needing trickle.In the prior art, small lid generally is screwed in big lid with screw thread, because it uses frequently, it is convenient inadequately that this connection mode just seems, the small lid that also has is to produce runner to push, to push away the mode of pulling out, finger direct contact runner, not enough health; On the other hand, when small lid is finished using, when covering enclosing cover, whether the user may forget small lid and seal, and so in actual use, is easy to occur the situation of seepage, makes troubles to the user.

Summary of the invention

To be solved in the utility model is that lid uses convenient and reliable inadequately problem, and a kind of lid of trickle quickly is provided.

For this reason, the technical solution adopted in the utility model is such: lid comprises lid and enclosing cover, enclosing cover and lid are free-running fit, it is characterized in that: be articulated with a spanner on the end face of lid, the lower surface of spanner possesses two highly different table tops, seamlessly transits between two table tops; Also be provided with plunger and spring in the lid, plunger top is the bulb shape, and is inconsistent with the lower surface of spanner, and the plunger stage casing is a joint pin, and bottom shape is consistent with the lid cross section, and matches with seal ring on the lid; Joint pin is with a spring outward, and spring lower end and lid relative fixed are fixed with a plunger button on the joint pin, and the upper end of spring this plunger of conflicting is buckled; When the high table top of the bulb of plunger and spanner lower end is conflicted, the seal ring driving fit mutually of plunger base and lid; When the low table of the bulb of plunger and spanner lower end is conflicted, leave the space between the seal ring of plunger base and lid.

Further, the part that spanner exposes the lid end face is that class is fan-shaped, and its pivoting point departs from mutually with the center of circle of lid, and in the stroke that pivoting point rotates, when the bulb conflict of the low table of spanner lower end and plunger, the fan-shaped afterbody of class stretches out the lid outer rim at spanner.

Further, the plunger button can be the cap shape, and the spring upper end is wherein ccontaining; The spanner end face is provided with depression; The low table of spanner lower surface is provided with depression, matches with plunger ball.

The utility model has two control positioies at spanner, correspond respectively to the high table top and the low table of lower end, when the needs uncover, rotating spanner, make the bulb of the low table of its lower end and plunger inconsistent, thereby plunger to pressing down, is made between the seal ring of plunger base and lid and leaves the space, and liquid can flow out via this space; When the needs close cap, the backward rotation spanner, then spring is with on the plunger top, and the high table top of plunger ball and spanner lower end is inconsistent, and plunger base and seal ring driving fit, the elastic force of spring is enough to both are compressed, and makes liquid to flow out.When lid during in open mode, on the low table of spanner lower surface depression is arranged, plunger ball snaps in wherein, makes that switch is unlikely to close voluntarily.The conversion of two states is fully by spanner control, and spanner only needs a finger manipulation, and rotational angle is also very little, and is therefore very convenient; And finger contact site no liquid flows through, and has more improved wholesomeness.

Spanner is set to off-centre, make pivoting point become fulcrum on the one hand, thereby may command is positioned at the plunger ball in the center of circle, makes on the other hand in automated procedure, and a position must be arranged, and its afterbody stretches out the lid outer rim.If the user has forgotten spanner is resetted after pouring out liquid in the container, then the spanner afterbody is given prominence to outside lid, and enclosing cover just can not close, and causes seepage with regard to having avoided because of user's carelessness like this, has improved reliability greatly.

The user can be placed on finger on the depression of spanner end face, thereby operates the utility model more easily.
