One end of the lanyard is fixed on the guillotine plug, and the other end of the lanyard is detachably fastened on the outer surface of the lower side wall of the cup body, and the lanyard is utilized. The one side of the silicone plug is positioned and hung on the inner lower side wall. The lanyard is designed to prevent the silicone plug from falling directly into the bottle after being pushed open.

The accommodating tube 2 has a tubular structure with open upper and lower ends. The tubular structure is sleeved in the inner lower side wall of the cap body, and the tubular structure has an interference fit with the inner and lower side walls, thereby increasing the accommodation. The friction between the outer surface of the tube and the inner surface of the lower side wall of the cap body avoids erroneous operation or slippage due to gravity; on the other hand, the sealing performance between the containing tube and the inner lower side wall can be increased. The housing tube 2 is not displaced relative to the inner lower side wall of the cap body 1 in the circumferential direction, but the housing tube 2 is moved up and down in the axial direction (ie, the vertical direction). The displacement distance of the upper and lower movements of the accommodating tube 2 is limited by the structure of the limiting element, and the structure of the limiting element is as follows: the inner surface of the inner side of the inner surface of the lid body 1 is formed with a circle extending radially inwardly. a positional boss 16; a circumferentially inwardly recessed surface of the receiving tube 2 is formed with a ring-shaped limiting groove 22 extending in the axial direction, the limiting groove extending a certain distance in the axial direction, the limit The positioning boss 16 is disposed in the limiting groove 22, and the distance of the limiting groove in the axial direction is the displacement distance of the receiving tube 2 to move up and down, and the displacement distance can be located in the receiving tube 2 The top opening portion of the bottom portion opens the barrier member, and the receiving tube cannot be detached from the upper end or the lower end of the lid body. The structure also enables the housing tube 2 to be positioned and coupled with the inner lower side wall of the lid body 1. At the same time, in order to ensure the sealing performance between the accommodating tube and the inner lower side wall, the upper and lower ends of the outer surface of the accommodating tube 2 and the inner surface of the inner lower side wall are respectively provided with a first sealing rubber ring 9 and The second sealing rubber ring 10 is preferably disposed at the upper and lower ends of the limiting groove 22 .

Further, a bottom portion 21 is formed at the bottom of the housing tube 2. The lower end surface of the housing tube 2 is entirely an inclined surface having one end high and one end low, and the inclined surface forms the top opening portion 21 together with the circumferential side wall of the lower end of the housing tube. The reason why the top opening portion is designed to be one end high and one end is low inclination is mainly that one end of the barrier member can be first opened when the barrier member is opened, and this design is especially used for the first time on the first barrier member (seal film). It is extremely useful to prevent the barrier (sealing film) from being completely detached and falling into the bottle body. At the same time, when the second barrier member (the silicone plug) is opened, the silicone plug which is not connected to the end of the lanyard can be opened first. (When designing the lanyard position, set the lanyard position to the side of the inclined surface and open the barrier.) In addition, except that the lower end surface of the housing tube 2 has an inclined surface as a whole, the bottom surface of the circumferential side wall of the lower end of the housing tube 2 also has an inner high and a low slope, and the outer edge of the inclined surface abuts against the inner side wall of the lid body. On the inner surface, the design is to prevent the vacuum effect in the tube, so that the top opening can be opened without a large effort.

The top cover 3 has a lid-like structure with an upper end closed and a lower end open. The top cover 3 can be arranged in a plurality of different colors according to different kinds of solute in the receiving chamber: for example, the solute is a medical white cover; the solute is medicinal Available in red or blue top cover; solute is a usable yellow top cover for household use; solute is a green top cover available for other general purpose uses; specific colors can be designed according to the application. The method for marking the solute at the same time is not limited to the above-mentioned labeling with different color top covers, and the labeling on the top cover may also be adopted, which will not be described in detail in the present application. The top cover 3 is disposed at the upper end opening of the receiving tube. The specific structure is: an external thread is formed on the outer peripheral side wall at the opening of the upper end of the receiving tube 2, and the inner peripheral wall of the top cover 3 is provided with an internal thread. When the external thread is screwed together, the top cover 3 is covered on the accommodating tube 2. The return spring 4 is sleeved on the outer surface of the housing tube 2, and the return spring is interposed between the upper surface of the connecting plate 14 of the cap body and the lower surface of the top cover 3.

The lower surface of the top cover 3, the inner surface of the receiving tube 2, the inner surface of the lower side surface of the cap body 1, and the upper surface of the barrier member 16 are collectively formed to form a receiving chamber 7, and the receiving chamber is provided with a solute. The top cover 3 can abut against the upper end surface of the receiving tube under the action of an external force to cause the top opening portion to open the blocking member, and the repositioning spring 4 can cause the top cover to drive the receiving tube to return to the original position under the elastic force.

The accommodating tube 2 included in the base structure of the press-removable adjustable volume storage bottle cap includes not only the accommodating tube which has been installed on the finished bottle cap as described above, but also includes a plurality of additional ones for replacement. Replacement of different lengths to accommodate the tube. During the use of the user, the storage tubes of different lengths can be replaced according to the difference in the mass of the solution placed in the accommodating chamber. If a large-capacity solute such as milk powder is required in the bottle cap, the user can replace the long-length accommodating tube; if a small-capacity solute such as a tablet needs to be placed in the cap, the user can replace the accommodating tube with a shorter length, here In combination with the use of the aforementioned second barrier member (silicone plug), the cap can be reused and the volume can be adjusted.

According to this design concept, if more large-sized solute needs to be placed in the bottle cap, the base structure of the repetitive adjustable volume storage cap can be scaled according to the horizontal scale enlargement to make the bottle cap size larger in diameter. The accommodating bin volume or the base structure of the press-fit adjustable volume storage cap is equally enlarged to the overall size to make the cap for a larger bin volume.

Its top opening function is achieved by the following process:

When it is used for the first time, an external force is applied to the top cover 3, and since the top cover 3 is fixedly connected with the accommodating tube 2, the top cover 3 drives the accommodating tube 2 to move downward, thereby driving the ejector portion located at the lower portion of the accommodating tube 2. When the 21 moves downward, the return spring 4 is deformed by extrusion, and the top opening portion opens the first barrier member (seal film), and the solute located in the accommodating chamber drops into the bottle body; after the top opening operation is completed, the return spring is completed. 4 accumulated elastic force is recovered upwards, and is topped to the lower surface of the top cover 3, so that the top cover 3 drives the accommodating tube 2 to return to the original position, thus completing the initial use of the cap; for subsequent repeated use, The solute is first placed in the accommodating cavity, and then the added second barrier member (the silicone plug) is inserted into the lower end opening of the inner lower side wall of the lid body, and the lanyard 62b is fastened to the lower side wall of the lid body. On the outer surface, the process of using the top opening and the process of returning to the original position are the same as described above.
