Detailed Description
The first embodiment is as follows: referring to fig. 1-5, a double-layer sealed aseptic beverage cap includes a cap body 13 covering a bottle body 11; a second sealing plate 17 is fixedly arranged in the bottle mouth cavity 12 of the bottle body 11; a telescopic straw 18 is arranged in the bottle mouth 12, and the telescopic straw 18 penetrates through the second sealing plate 17; a first sealing plate 15 is fixedly arranged on the lower wall of the cover body cavity 14 of the cover body 13, the first sealing plate 15 is in sliding connection with the inner wall of the bottle mouth cavity 12, and a sealing cavity 19 is formed at the bottom end of the first sealing plate 15;
the fixed sealed piece 20 that is equipped with of 19 upper walls in sealed chamber, be equipped with slip chamber 24 in the sealed piece 20, link up about the slip chamber 24, 24 lower walls in slip chamber communicate and are equipped with piston chamber 28, sealed piece 20 bottom mounting is equipped with gasbag 26, it is equipped with push pedal 22 to slide from top to bottom in the slip chamber 24, push pedal 22 bottom mounting is equipped with piston block 23, piston block 23 and 28 piston chamber piston connections, 28 bottom mounting in piston chamber is equipped with seal membrane 25, the fixed stay cord 27 that is equipped with between seal membrane 25 top and the piston block 23 bottom.
The sealing block 20 is connected with the inner wall of the telescopic straw 18 in a sliding mode, after the upper end of the telescopic straw 18 is attached to the lower end of the push plate 22, the sealing block 20 can seal the telescopic straw 18, and when the sealing block extends into the telescopic straw 18, the sealing block is in interference fit with the inner wall of the telescopic straw 18.
The sealing film 25 is in a free state in a closed state to separate the piston chamber 28 from the air bag 26, and the sealing film 25 is ruptured only after being pulled upward by the pulling rope 27 to communicate the air bag 26 with the piston chamber 28.
A thrust spring 21 is fixedly arranged between the top end of the push plate 22 and the upper wall of the sliding cavity 24, when the sealing film 25 is in a closed state, a certain air pressure is arranged in the piston cavity 28, and at the moment, the thrust spring 21 cannot push the push plate 22 to move.
When the sealing film 25 is in a communicated state and the telescopic suction pipe 18 does not push the push plate 22, the thrust spring 21 can push the piston block 23 to slide downwards in the piston cavity 28, so that the gas in the piston cavity 28 is squeezed into the air bag 26.
In the initial state, the air bag 26 is in an uninflated state and can be inserted into the telescopic straw 18. The part of the telescopic straw 18, which is positioned on the upper side of the second sealing plate 17, is of a flexible structure, and the part of the telescopic straw 18, which is positioned on the upper side of the second sealing plate 17, can be stretched up and down; the air bag 26 can be attached to and in interference connection with the telescopic straw 18 after being expanded, and the beverage is positioned at the lower side of the second sealing plate 17.
The outer circular surface of the bottle body 11 is in threaded connection with the cover body 13, and when the cover body 13 and the bottle body 11 are in threaded connection with the top end of the bottle body 11 and tightly attached to the upper wall of the cover body cavity 14, the cover body 13 can seal the top end of the bottle mouth cavity 12.
By the fixing of the piston block 23, the remaining space of the sealed cavity 19 is an annular cavity corresponding to the telescopic suction pipe 18.
Stretch into body 11 to lid chamber 14 in, thereby rotate lid 13 and connect both sides screw thread 16, thereby be connected lid 13 and body 11, simultaneously first closing plate 15 stretches into to bottleneck chamber 12 in, flexible straw 18 is in same vertical direction with sealed chamber 19 this moment, the downstream movement through lid 13 makes flexible straw 18 top stretch into to sealed chamber 19 in, the disc is laminated with the interior round wall of sealed chamber 19 outside flexible straw 18 this moment, sealed piece 20 stretches into in the flexible straw 18 and then seals flexible straw 18, stretch into sealed chamber 19 through flexible straw 18, flexible straw 18 promotes push pedal 22 and overcomes thrust spring 21's thrust and rebound, thereby it drives piston block 23 rebound to move up to the rebound through the rebound of push pedal 22, thereby pulling stay cord 27 rebound, and then draw seal membrane 25 to breaking, and then communicate piston chamber 28 with gasbag 26.
When the drink in the bottle oral cavity 12 needs to be drunk, thereby manually rotate the lid 13 and make the separation of both sides screw thread 16, thereby make lid 13 and body 11 separate, move to the 19 outside of sealed chamber and can't be with push pedal 22 bearing this moment through flexible straw 18, thereby push pedal 22 downstream is promoted to thrust through thrust spring 21, and then drive piston block 23 downstream and extrude the air in the piston chamber 28 downwards, and then promote the air and pass seal membrane 25 and extrude into in the gasbag 26, thereby it hugs closely with flexible straw 18 inner wall to drive the inflation of gasbag 26 through the inflation of gasbag 26, thereby the frictional force between rebound and gasbag 26 and flexible straw 18 through lid 13 this moment, and then stretch out and draw back straw 18, thereby the person of facilitating the use can drink the drink in the bottle oral cavity 12 through the flexible straw 18 of extension.
