Description

The false proof pressure purger of bottle cap

The utility model relates to the false proof pressure purger of a kind of bottle cap.

Existing bottle cap manyly needs Bottle opener or just bottle cap can be opened with very big power, and is very inconvenient when the customer is used, especially at the whilst on tour of going out; And most bottle caps do not have false proof and decompression simultaneously.

The purpose of this utility model is to provide a kind of bottle cap false proof pressure purger, and this device can make bottle cap have false proof and decompression simultaneously, and sealing simple in structure, that can be widely used in canned food, and safety, laborsaving is easy to use during unpacking.

The purpose of this utility model is achieved in that in the middle part of bottle cap 1 porose, and bottle cap 1 inboard is embedded with cylinder ring 5 all around in the hole, and the hole surface at bottle cap 1 middle part above cylinder ring 5 is coated with anti false film 7.There is the axle 3 that is with spring 2 inboard of cylinder ring 5, and axle 3 top is that button 6, its underpart are connected with stopper 4 and place outside the return-air hole at middle part, cylinder ring 5 belows,

Another embodiment of the false proof pressure purger of bottle cap of the present utility model is that the top of described axle 3 is that the stopper 4 of draw ring 8, its underpart places cylinder ring 5 inboard return-air hole tops.

The utility model is owing to be in the middle part of bottle cap false proof pressure purger to be set, the pressure that the principle equilibration flask of this device root a tree name atmospheric pressure is inside and outside, thereby make when opening bottle cap convenient and laborsaving, its structure just has axle and the stopper that is overlapping spring in bottle cap middle part embedding one cylinder ring, cylinder ring inboard, the elasticity of spring can make axle reset, when the top of axle is button, thereby the stopper of axle bottom places the return-air hole below of cylinder ring below and stops up return-air hole and makes and form a vacuum in the bottle, presses the button can reduce pressure and easily open bottle cap; The top of axle is when being draw ring, and the stopper of axle bottom places on the return-air hole of cylinder ring below power and stops up return-air hole, and the pull-up draw ring can reduce pressure and easy-to-open bottle cover; Simultaneously in the motion of the anti false film Sang Keyin button of bottle cap surface coverage or draw ring and impaired, bottle cap is identified when secondary uses easily, and then reaches false proof purpose.Because it is simple to operate, open easily, convenient, can both at will open so connect general women, old man even children.

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the cutaway view of the false proof pressure purger of the utility model bottle cap.

Fig. 2 is the cutaway view of the another kind of embodiment of the false proof pressure purger of the utility model bottle cap.

Among Fig. 1, the middle part of bottle cap 1 is porose, and bottle cap 1 inboard is embedded with cylinder ring 5 around the hole, and the surface coverage of bottle cap 1 anti false film 7; The middle part, below of cylinder ring 5 is return-air holes, there is the axle 3 that is with spring cylinder ring 5 inboards, the top of axle 3 is that button 6, its underpart of being placed in the middle hole, cylinder ring 5 tops are that stopper 4, stopper 4 are placed on the return-air hole below, press the button 6, anti false film 7 is destroyed, spring 2 is squeezed, and axle 3 moves down, and can easily bottle cap 1 be opened thereby stopper 4 is left in return-air hole, the air admission bottle.Among Fig. 2, another kind of embodiment of the present utility model is: the top of axle 3 is connected with draw ring 8, the stopper 4 of axle 3 bottoms places top, cylinder ring 5 inner return-air holes, pull-up draw ring 8, anti false film 7 is destroyed, and spring 2 shrinks, and stopper 4 leaves return-air hole, in the air admission bottle, thereby bottle cap 1 easily is unlocked.Device of the present utility model can reset after use because of the elastic force of spring.
