[0023] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0024] Embodiment 1: As shown in Figure 1 , Figure 2 and Figure 3 , a push-type storage bottle cap of the present invention includes a first bottle cap 1. A concave cylinder 2 is provided in the middle of the first bottle cap 1. The concave cylinder 2 is provided with a hollow structure. A pneumatic storage tube 3 is arranged inside the concave cylinder 2. A liquid outlet tube 4 is provided in the middle of the bottom end of the pneumatic storage tube 3. A round hole 5 for the liquid outlet tube 4 to be inserted is provided at the center of the bottom of the concave cylinder 2. A matching positioning component is provided on the round hole 5 and the liquid outlet tube 4. A matching limit component 6 is provided at the connection between the outer wall of the pneumatic storage tube 3 and the inner wall of the concave cylinder 2. A sealing piece 7 for sealing the round hole 5 is provided at the bottom end of the concave cylinder 2; A ring of upward pipe connection flanges 8 is provided at the top opening of the first bottle cap 1. The top end of the pipe connection flange 8 is threadedly connected to a second bottle cap 9.

[0025] Among them, a first thread 10 is provided on the inner wall of the first bottle cap 1, and the first bottle cap 1 can be threadedly connected to the storage bottle through the first thread 10.

[0026] Among them, a first sealing ring 11 is provided on the inner wall of the first bottle cap 1, which can play a good sealing role in the connection between the first bottle cap 1 and the storage bottle.

[0027] Among them, the positioning component includes a positioning groove 12 opened at the top end of the round hole 5, and a positioning convex ring 13 is provided on the outer wall of the liquid outlet pipe 4 and is matched with the positioning groove 12. The inner diameter of the round hole 5 is larger than the outer diameter of the liquid outlet pipe 4, and the maximum outer diameter of the positioning convex ring 13 is larger than the inner diameter of the round hole 5, which can position and support the liquid outlet pipe 4 and facilitate continuous pressing of the pneumatic storage tube 3.

[0028] Among them, the limiting component 6 includes a first limiting thread 14 provided on the inner wall of the concave cylinder 2, and a second limiting thread is provided on the outer wall of the pneumatic storage tube 3 and is threadedly connected with the first limiting thread 14, which can limit the pneumatic storage tube 3 and prevent the pneumatic storage tube 3 from moving downward under its own gravity and piercing the sealing piece 7.

[0029] Among them, the inner diameter of the second bottle cap 9 is equal to the inner diameter of the first bottle cap 1, and a second thread 15 of the same specification as the first thread 10 is provided on the inner wall of the second bottle cap 9, so that after the first bottle cap 1 is unscrewed from the storage bottle, the second bottle cap 9 can be screwed onto the storage bottle.

[0030] Among them, the bottom end of the liquid outlet pipe 4 is set to any one of a serrated shape and a pointed shape to facilitate piercing the sealing film.

[0031] Among them, when the first limiting thread 14 and the second limiting thread are threadedly connected, the top end of the pneumatic storage tube 3 is higher than the top end of the first bottle cap 1, and the bottom end of the liquid outlet pipe 4 does not contact the sealing piece 7.

[0032] During operation, for this kind of pressing-type storage bottle cap, after a pressing-type storage bottle cap is assembled to the corresponding storage bottle, during use, first unscrew the second bottle cap 9, press down the pneumatic storage tube 3, so that the second limiting thread on the pneumatic storage tube 3 is disengaged from the first limiting thread 14 in the first bottle cap 1. At this time, the liquid outlet pipe 4 passes through the round hole 5 and pierces the sealing piece 7 until the positioning convex ring 13 is matched with the positioning groove 12. Then, continuously press, so that the positioning convex ring 13 and the positioning groove 12 of the round hole 5 are mutually extruded, forcing the liquid outlet pipe 4 to move into the pneumatic storage tube 3. When the liquid outlet pipe 4 enters the pneumatic storage tube 3, the liquid in the pneumatic storage tube 3 enters the liquid outlet pipe 4 under pressure and is injected into the storage bottle. After the injection is completed, unscrew and open the first bottle cap 1 (the first bottle cap 1 can be discarded), screw the second bottle cap 9 tightly onto the storage bottle, and then shake well. The two materials can be stored separately, avoiding the situation that the two materials are mixed and cause adverse reactions, shortening the shelf life, or even generating harmful substances. The mixing of raw materials can be achieved by pressing, which is convenient for consumers to use. It has the characteristics of simple structure and easy operation, without significantly modifying the bottle body and the filling process, reducing the manufacturing cost and the assembly cost.

[0033] Example 2, as Figure 4 、Figure 5 and Figure 6 As shown in Figure 6 , on the basis of Embodiment 1, a further improvement is made. A storage bin 17 with an open bottom is provided inside the second bottle cap 9. The top end of the storage bin 17 protrudes out of the second bottle cap 9, and the extended part of the storage bin 17 is set as either a circle or a frustum of a cone, increasing the storage space of the storage bin 17, avoiding the problem of too small storage space, and also facilitating the discharge of the materials inside the storage bin 17. A sealing film 18 is provided at the opening of the storage bin 17.

[0034] During operation, when a push - type storage bottle cap is assembled to the corresponding storage bottle, during use, first unscrew the second bottle cap 9, press down the pneumatic storage tube 3, so that the second limit thread on the pneumatic storage tube 3 disengages from the first limit thread 14 inside the first bottle cap 1. At this time, the liquid outlet tube 4 passes through the round hole 5 and pierces the sealing piece 7 until the positioning convex ring 13 matches the positioning groove 12. Then continue to press, so that the positioning convex ring 13 and the positioning groove 12 of the round hole 5 squeeze each other, forcing the liquid outlet tube 4 to move into the pneumatic storage tube 3. When the liquid outlet tube 4 enters the pneumatic storage tube 3, the liquid in the pneumatic storage tube 3 enters the liquid outlet tube 4 under the action of pressure and is injected into the storage bottle. After the injection is completed, unscrew and open the first bottle cap 1 (the first bottle cap 1 can be discarded), then tear off the sealing film 18, pour the materials inside the storage bin 17 into the storage bottle, tighten the second bottle cap 9 onto the storage bottle, and then shake well. The three materials can be stored separately, avoiding the situation that adverse reactions occur after the materials are mixed, resulting in a shortened shelf life or even the generation of harmful substances. The mixing of raw materials can be achieved through simple operations such as pressing, which is convenient for consumers to use. It has the characteristics of simple structure and easy operation, without the need for significant modification of the bottle body and filling process, reducing the manufacturing cost and assembly cost. At the same time, in Embodiment 1, an additional material is added, greatly increasing the product combination. For example, in the beverage field, consumers can adjust the beverage flavor according to their preferences, expanding the application scenarios.
