Abstract

The utility model relates to a plastic bottle top which is a replacing product for soy sauce and vinegar bottles. The plastic bottle top has the advantages that a bottle can be taken up to pour after the plastic bottle top is unscrewed; the unscrewing direction does not need to be seen, the plastic bottle top does not need to cut, and liquid can not rush out; liquid speed is uniform and stable; a bottle jack can not leave residue; after the plastic bottle top is screwed, seal is reliable; the plastic bottle top is convenient and sanitary.

Description

Bottle cap

The utility model is a kind of plastic bottle closure, is made up of bottle stopper and spiral cover, is mainly used in soy sauce, vinegar or adorns on other fluid bottle.

Soy sauce in the market, the plastic closure on the vinegar bottle have two kinds, and a kind of is single lid, uncapping, raffinate are being arranged on when the falling liquid bottleneck, can make that hand, bottle are outer, be polluted on the table.Another kind is made up of bottle stopper and spiral cover, there are the plastics of two projectioies on its bottle stopper top, expose small sircle hole and semicircle hole that fluid is used that an air inlet is used after cutting with cutter, this bottle cap can not make hand stain raffinate, but open when covering for the first time, need look for a cutter to cut and seal plastics, to see direction earlier in when falling liquid, aperture upwards, semicircle orifice is downward, can make a dash out careless just spattering on the table hurry up once as action, after pouring out some liquid, just can not trickle automatically, hand ceaselessly must be shaken or toppled over just repeatedly can continue to flow out.Can stay raffinate on the top of bottle stopper and the screw thread, seem black unhygienic.

The purpose of this utility model provides a kind of can the sealing, and the lid of outwarding winding must not watched the bottleneck direction with regard to liquid in the pourable bottle, flow rate of liquid is steadily even, does not leave raffinate, the plastic bottle closure that sanitation and hygiene are easy to use on the bottle stopper mouth.

In order to solve above-mentioned task, scheme of the present utility model is: the liquid outlet of doing a trumpet type on the bottle stopper top, the centre of liquid outlet is provided with an air inlet pipe, a little induction opening is opened in the bottom of air inlet pipe, a bumper ring is set before the liquid outlet passage, form a buffer zone between bumper ring and the liquid outlet, the seal ring of a back taper is set in the spiral cover, seal ring is pressed on the inner conical surface of liquid outlet and forms sealing surface after lid screws.

Above-mentioned bottle cap is owing to be provided with the seal ring of a back taper in spiral cover, after lid screwed, seal ring was pressed on the tubaeform inner conical surface of bottle stopper liquid outlet, so liquid that can not leaks.When uncover can fall liquid partial application again.Because buffer zone has been arranged, topple over action hurry up in the bottle liquid that can not make a dash out.Admission port need not watch the direction of admission port just dumpable in central authorities so at will pick up bottle.The internal diameter of air inlet pipe is thicker, and the bottom inflow hole is done lessly, liquid outlet and induction opening meeting while fluid when liquid has just begun, because of induction opening less, amount in the liquid inflow air inlet pipe seldom, liquid stops in thicker air inlet pipe incessantly, therefore air inlet pipe remains empty state, between induction opening and the liquid outlet certain distance is arranged, liquid body gravity effect when toppling over has difference of pressure between 2, the fluid pressure that continuously outflows air inlet position along with liquid in the bottle reduces gradually, when less than barometric pressure, air just enters in the bottle from induction opening, because difference of pressure is that the speed that certain therefore liquid flows out is stable.The liquid outlet of bottle stopper is done flue, just can not flow backwards along appearance when the end of falling liquid and drop down, and does not retain so bottle stopper does not have raffinate outward, and it is neat and tidy to seem just to seem.

The external form of the utility model bottle cap is consistent with existing bottle cap external form on the market basically, has just changed inner structure, therefore can increase about some quantity of plastics 1 grams, and job operation does not become, so the cost increase seldom.But used very convenient, not only domestic will the use in a large number, and annual export volume also is very huge.

Be described further below in conjunction with drawings and Examples.

Fig. 1 is half view and half longitudinal diagram of the utility model embodiment.

Bottle stopper 1 shown in Figure 1 is tightly to be enclosed within soy cruet, vinegar bottle or to adorn on the bottleneck of other liquid, with the bottleneck contact position leakproof circle is being arranged, be threaded on the bottle stopper 1, spiral cover 2 is arranged on it, back taper seal ring 3 is arranged in the spiral cover 2, after spiral cover 2 was tightened on bottle stopper 1, conical seal ring 3 just was pressed on the tubaeform inner conical surface of bottle stopper liquid outlet 4, formed sealing surface and prevented a bottle interior leak of liquid.There is air inlet pipe 5 in central authorities at liquid outlet 4, and air inlet pipe 5 relies on 4 muscle to fix, and in its bottom one less induction opening 6 are arranged, because induction opening is in central authorities, just can fall liquid so any direction is picked up bottle, must not see that induction opening is whether above liquid outlet.Liquid outlet 4 and 6 meeting while of induction opening trickle when liquid has just begun, because induction opening 6 is very little more much smaller than air inlet pipe 5, the liquid that induction opening 6 flows out seldom, in air inlet pipe, stop incessantly, basically keeping empty state in the air inlet pipe, along with liquid in the bottle constantly flows out, the fluid pressure at induction opening 6 places reduces gradually, when less than barometric pressure, air will enter in the bottle from induction opening 6, between induction opening 6 and the liquid outlet 4 certain distance is arranged, it is poor to produce certain pressure under the liquid gravity influence, so the speed that liquid flows out is stable.One bumper ring 7 is set before the passage of liquid outlet 4, just forms buffer zone between buffering Fig. 7 and the liquid outlet 4, if the action of pouring liquid more like this, the liquid in the bottle can not make a dash out yet.Liquid outlet 4 places are provided with flaring pour spout, and like this when the end of falling liquid, liquid just can be along the trickling of the bell-mouthed back side, so just neat and tidy on the bottle stopper, does not have raffinate to retain, look with regard to clean hygiene many.

Claims (1)

1, a kind of bottle cap of forming by bottle stopper and spiral cover of plastics, it is characterized in that: the liquid outlet of bottle stopper is done flue, there is air inlet pipe in central authorities at liquid outlet, in the bottom of air inlet pipe less induction opening is arranged, bumper ring is set one before the passage of liquid outlet, make to form buffer zone between liquid outlet and the bumper ring have one seal ring can be pressed on the liquid outlet of bottle stopper in the spiral cover.
