The quantitative self-priming bottle cap assembly for the essence packaging bottle is in threaded fit with a bottle body, and the self-priming function is realized by the following steps: at initial state, top cap 1 and end cover 3 are the contact state, and when unscrewing the bottle lid subassembly, the screw thread of tooth lid 7 and bottleneck breaks away from, and spring 5 limit state cancels, and spring 5 upwards pops open end cover 3, and end cover 3 drives top cap 1 and moves up, and top cap 1 drives the cover and moves up at the piston 4 of cylinder 12 in the top cap, and the interior air of piston 4 top is outwards discharged, and the passageway through straw 9 is inhaled the material body inside the straw simultaneously. When the cap 1 is pressed again, the cap 1 pushes the piston 4 to move downwards, and the air is extruded to push the material body in the straw 9 out for the consumer to use.

Referring to fig. 2 and 11, the function of precisely controlling the suction amount is implemented as follows: when the end cover 3 is pressed and rotated downward, the end cover bosses 34 may be clamped in the first arc-shaped recess 231, the middle portion 232, or the second arc-shaped recess 233 of the groove bottom of the corresponding capping groove 23, defining that the two end cover bosses 34 are located in the first arc-shaped recesses 231 of the groove bottoms of the two capping grooves 23 in a one-to-one correspondence as the position a, and the two end cover bosses 34 are located in the second arc-shaped recesses 233 of the groove bottoms of the two capping grooves 23 in a one-to-one correspondence as the position B. At the position A, the state is an initial state, at the time, the end cover 3 is not pre-pressed downwards, the piston 4 is not moved downwards, the motion stroke of the piston 4 is a designed amount, and therefore the amount of the automatic suction material body is 100% of the designed suction amount; when the top cover 1 is pressed and rotated downwards, the end cover 3 is pressed and rotated downwards at the same time, and when the top cover is rotated to the position B, the piston 4 moves downwards to a proper position due to the limit of the second arc-shaped concave part 233, the motion stroke of the piston is shortened, the volume of the suction material body is reduced, and the amount of the automatic suction material body is reduced. Therefore, in the process of moving from the position A to the position B, the suction amount of the essence can be accurately controlled, for example, when the two end cover bosses 34 are located in the middle part 232 of the bottoms of the two embedding cover grooves 23 in a one-to-one correspondence manner, the moving stroke of the piston is another numerical value, the amount of the suction material in the suction pipe 9 is different from that in the position B, the amount of the suction material can be controlled by a consumer, and waste and pollution to the content in the bottle are reduced.

In conclusion, the quantitative self-sucking bottle cap assembly for the essence packaging bottle can automatically suck materials, accurately control the sucking amount, reduce the use process of needing to be pressed additionally, enable consumers to control the amount of the sucked materials, and reduce waste and pollution to the contents in the bottle.
