Abstract

The utility model relates to a sealing cap, which is composed of a main cap, an outer cap and a casing. The cap surface of the main cap is an open, a relative small model block is arranged in the center of the cap open so that a gap is arranged between the cap open and the model block, the model block is connected with the cap open by a reinforcing rod, and a dimension sized through hole which is slight smaller than the model block is arranged on the center of the cap surface of the outer cap. When the outer cap is covered and tightly pressed on the main cap, the model block is pressed into the through hole to form a seal, and when the outer cap is opened, the through hole is separated from the model block only by pulling the outer cap upwardly, and the whole process need not to take the cap out from the bottle neck. The utility model has reasonable structure, good sealing performance, convenient and sanitary carrying and use and wide application range.

Description

A kind of stretching-compression type seal bottle cap

The utility model relates to a kind of accessory of liquid holding bottle, and particularly a kind of unlatching is seal bottle cap easily.

The bottle of holding liquid commonly used can rough segmentation be two kinds of edible liquid of splendid attire and non-edible liquid etc. on purposes, the beverage bottle of edible liquid Packaging Bottle such as mineral water and so on, its bottle cap that adopts mostly is screw cap, and this bottle cap is once turning on, with after cover lid again, just destroyed its leak tightness, bottle is once toppling over, and liquid tends to ooze and releases, and drink always bottle cap to be outwarded winding at every turn and take out, so both unhygienic also inconvenient, and the lid of taking out drops sometimes and loses, and causes trouble.The Packaging Bottle of non-edible liquid Packaging Bottle such as washer solvent and so on, mostly its Bottle cap structure that adopts is to have the boss of a perforate on the capping of threaded cap, the upper end of lid is provided with a top cover, top cover is the middle affixed stopper of one side down, its shape and position are corresponding to the hole of capping, and the size of stopper is bigger slightly than aperture, unstops during use, dumpablely go out liquid, with after again stopper is filled in the aperture, top cover promptly covers, and is more convenient when the bottle cap of this non-edible liquid holding bottle uses, but when the event pouring liquid of boss being arranged owing to capping, often there is raffinate to flow out and stagnates on capping through boss, not enough health, in addition, this lid is comparatively suitable as the bottle cap of non-edible liquid Packaging Bottle, as be developed as the bottle cap of beverage bottle, then can because of top cover and boss so, hinder and drink, structure is reasonable inadequately, thereby field of application is restricted.

The utility model provides the main lid of a kind of employing to match with enclosing cover at the problem that above-mentioned Bottle cap structure exists, and need not take out from bottleneck when uncapping, and good seal performance during capping can be combined as the bottle cap that eats liquid bottle and non-edible liquid bottle again.

The purpose of this utility model is achieved in that

The stretching-compression type seal bottle cap, by going up little main lid down greatly, enclosing cover and the outer cover that enclosing cover covers in therebetween formed, main lid is flexible connection with bottleneck, outer cover is flush fit with main lid, it is characterized in that: the capping of main lid is uncovered, the capping edge has a flange to make the usefulness of limited step, there is a type piece in lid mouthful central authorities, and this type piece is connected it with the reinforced rib form above the lid edge with a lid mouthful inwall, the shape of type piece is corresponding with the lid mouth, size makes between type piece and the lid mouth and forms certain clearance then than being little, and enclosing cover capping central authorities open a through hole, the shape of this through hole and position correspond to the main type piece that covers, and its size is slightly littler than type piece.

The shape of main lid lid mouth of the present utility model can be circle, ellipse or polygon etc.

The main inwall that covers narrow neck part outer wall and enclosing cover is respectively equipped with limited step on the relevant position.

Below in conjunction with accompanying drawing 1-2 most preferred embodiment of the utility model is made more detailed description.

Fig. 1 is the structure cutaway view of a preferred plan of the utility model.

Fig. 2 is a structure upward view of the present utility model.

From Fig. 1-2, as can be seen the utility model by down big little mainly cover 1, the enclosing cover 2 and outer cover 3 that enclosing cover 2 covers in therebetween formed, enclosing cover 2 is to be placed on the main narrow neck part that covers 1 top, and outer cover 3 utilizes limited step 5 to snap in main 1 limited step 6 location of covering, and realizes flush fit between the two.Main 1 the base inner wall of covering is provided with on the bottleneck that outside thread is tightened in liquid bottle band standard female.

Main 1 the lid mouth 12 employing opened rounds of cover are uncovered, lid mouthful 12 central authorities have a circular type piece 4 to make stopper usefulness, the external diameter of this type piece 4 is littler than the internal diameter of lid mouth 12, and above main 1 the lid of covering along 11, make between type piece 4 and the lid mouth 12 and form certain clearance, with reinforced rib 13 they are coupled together between the inwall of type piece 4 and lid mouthfuls 12, main 1 the lid of covering is made a flange 7 along 11, cover 1 top narrow neck part outer wall the master and be provided with limited step 10, the capping central authorities of enclosing cover 2 drive a manhole 14, the internal diameter of this through hole 14 is slightly littler than the main external diameter that covers 1 type piece 4, during capping, enclosing cover 2 is covered the master cover 1 narrow neck part, and compress downwards, the material that lid adopts is a thermoplastic material, have certain elasticity, the at this moment main type piece 4 that covers on 1 utilizes elasticity to be pressed in the through hole 14 of enclosing cover 2, clogs through hole 14, main 1 the limited step 10 of cover withstands the limited step 9 of enclosing cover 2 and enclosing cover 2 is located, and lid is in the capping state and forms sealing; When opening lid, main 1 the base of covering need not be turned on from bottleneck and taken out, as long as pinch the flange 8 that enclosing cover 2 covers along 11 with hand, be pulled upwardly enclosing cover 2, the through hole 14 of enclosing cover 2 leaves main 1 the type piece 4 that covers, at this moment the limited step 9 of enclosing cover 2 inwalls cover 1 and covers along 11 flange 7 and withstand the location by main, also form certain clearance between type piece 4 and the through hole 14, bottle cap is in opening, inclination liquid bottle, liquid will be from bottle through main 1 lid mouth 12 and the gap between the type piece 4 cover, the outflow of the gap between the through hole 14 of type piece 4 and enclosing cover 2 again is for drinking or using.

Earlier the master being covered 1 base when the utility model uses is tightened on the bottleneck, then as long as finish the action of drawing or pressing down on the enclosing cover 2, bottle cap corresponding presenting uncapped or the state of capping, whole process need not be taken out bottle cap from bottleneck, and applicable to the bottle cap of making edible liquid bottle and non-edible liquid bottle, this bottle cap applied range, simple and reasonable for structure, good seal performance carries, uses convenient and sanitary, has also improved the grade and the class of packaging simultaneously.
