Abstract
The utility model relates to a bottle cap, particularly a novel bottle cap capable of being conveniently twisted off. The utility model comprises a cap body, and is characterized in that the cap body is provided with a base provided with a through hole, the upper end of the through hole is provided with a sealing cap and the lower end of the through hole is provided with a layer of film. The utility model can balance the internal pressure and the external pressure of a bottle, and can easily twist off the bottle cap. When the internal pressure of the bottle is too high, the pressure is automatically relieved and the bottle is prevented from exploding. The utility model has the advantages of simple structure, easy machining and low cost.
Description
Technical field
The utility model relates to a kind of bottle cap, the specifically a kind of novel bottle cap that can conveniently turn on.
Background technology
Bottle is a kind of packing container that is used for splendid attire food, beverage and other article.According to the article difference of institute's splendid attire, bottle interior pressure is not normal pressure generally, and what have is lower than barometric pressure (as vacuum packaging), and what have is higher than barometric pressure (as the pressure packing).No matter be vacuum packaging or pressure packing, as long as pressure of the inside of a bottle is different with the outer barometric pressure of bottle, all can cause bottle cap to turn on difficulty in various degree, bottle external and internal pressure difference is big more, the desired power of twist-off closure is also big more, also can cause bottle cap locked can not turning on fully sometimes; If bottle interior hypertonia even can cause bottle blast to be hurted sb.'s feelings becomes the danger factor that threaten personal safety in addition.Existing bottle cap kind is a lot, generally is divided into individual layer and multiple-structure, and its effect major advantage is that sealing is tight, but all there is the defective of turning on difficulty in they.
The utility model content
Technical problem to be solved in the utility model is: the defective at existing product exists provides a kind of novel bottle cap that can conveniently turn on, to remedy the deficiency of existing product.
The technical solution of the utility model is achieved in that it comprises lid, is characterized in that: a pedestal is housed on the lid, has through hole on the pedestal, the through hole upper end is provided with seal cover cap, and the lower end of through hole is provided with thin film.The lower end of described seal cover cap is provided with a boss, and boss is inserted in the through hole; Also be provided with ear shape handle on the seal cover cap; The side of described pedestal is provided with draw-in groove, has the hole in the middle of the lid, and draw-in groove is stuck in the hole that has in the middle of the lid.
The utlity model has following advantage:
1, balance bottle external and internal pressure, easily twist-off closure;
2, when the bottle interior hypertonia, releasing pressure automatically prevents the bottle blast;
3, simple in structure, handling ease, with low cost, convenient enforcement.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of seal cover cap of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprises lid 1, and a pedestal 2 is housed on the lid 1, has through hole 3 on the pedestal 2, and through hole 3 upper ends are provided with seal cover cap 4, and the lower end of through hole 3 is provided with thin film 5.The lower end of described seal cover cap 4 is provided with a boss 6, and boss 6 is inserted in through hole interior 3; Also be provided with ear shape handle 8 on the seal cover cap; The side of described pedestal 2 is provided with annular slot 7, has the hole in the middle of the lid 1, and annular slot 7 is stuck in the hole that has in the middle of the lid 1.
The principle of work of pressure balance type explosion protection is:
1, against vacuum Packing Condition, because bottle interior pressure is lower than external pressure, under barometric pressure and seal cover cap self elastic reaction, the seal boss on the seal cover cap tightly is pressed on the pedestal centre hole, to keep apart inside and outside the bottle, keep the vacuum state of bottle interior.Twist-off closure is at first mentioned seal cover cap 4 by the ear shape handle 8 of seal cover cap if desired, breaks film 5, and extraneous air enters bottle interior by the pedestal centre hole, and bottle interior is recovered atmospheric pressure state, makes the unlatching of bottle cap become very light.
2, for the pressure Packing Condition: because bottle interior pressure is higher than external pressure, under barometric pressure and film 5 self elastic reaction, film 5 tightly is pressed on the pedestal centre hole, will keep apart inside and outside the bottle, keeps the pressure state of bottle interior.Twist-off closure if desired, at first mention seal cover cap 4 by the ear shape handle 7 of seal cover cap 4, use a thin rod shape thing (as toothpick etc.) to push film 5 downwards open then and discharge the bottle interior pressure, bottle interior is recovered atmospheric pressure state, makes the unlatching of bottle cap become very light.
3, explosion-proof: equally to the pressure Packing Condition; if because of accidental cause bottle interior hypertonia; film 5 can at first break under the effect of bottle interior high pressure before the bottle blast; seal cover cap 4 is pushed open by bottle interior air pressure subsequently; thereby discharge bottle interior pressure; prevent the bottle blast, play a kind of protective effect.
