Absorption bottle is usually equipped with rubber cap to ensure the sealing of bottle and prevent external pollution. However, the existing absorption bottle rubber cap design has some technical problems, which brings inconvenience and potential experimental error in practical application. The existing rubber cap is smooth from top to bottom, and the inner diameter is almost equal to the outer diameter of absorption tube, to strengthen the sealing. But this design leads to the outer wall of absorption tube and the inner wall of rubber cap contact area is huge when putting on or taking off rubber cap, and the friction force increases significantly, so that rubber cap is difficult to operate, and even may appear unable to take off, take off when damaging absorption bottle or stabbing the hand.

A flexible material resistant to high temperature and chemical corrosion, such as silicone or rubber, is selected as the main material of the cap body 110 and the cap top 120. The flexible material is molded into the cap body 110 and the cap top 120 by injection molding process. The inner wall of the cap body 110 is designed with a plurality of convex rings 111. The design of the convex rings 111 reduces the contact area between the rubber cap 100 and the absorption bottle tube 200, so that the friction is reduced when the rubber cap 100 is put on or taken off, the operation is more convenient, and the risk of damaging the absorption bottle or pricking the hand is reduced. The height of the convex ring 111 is 1mm, and the width is 2mm, so as to ensure that the cooperation with the absorption bottle tube 200 is tight and the friction is moderate. The design of the height and width of the convex ring 111 ensures that the rubber cap 100 can still maintain good shape and performance after repeated use, and enhances the structural stability. The size design of the convex ring 111 ensures that the rubber cap 100 and the absorption bottle tube 200 are tightly matched, and avoids excessive friction, achieving a good balance.

[0040] The cap top 120 is a hemispherical solid structure to enhance the stability and sealing performance of the rubber cap 100. The inner top surface 121 is designed as a plane to facilitate the adhesion with the mouth of the absorption bottle tube 200. Since the inner top surface 121 is a plane, it can be tightly adhered with the mouth of the absorption bottle tube 200, effectively preventing the absorption liquid from spilling, and significantly improving the sealing performance. The design of the planar inner top surface 121 effectively prevents the absorption liquid from being adsorbed in the space at the top of the rubber cap 100, ensuring the accuracy of the volume of the absorption liquid, which is crucial for the reliability of experimental data.

[0041] Embodiment 2 is described in Figures 1 to 3 On the basis of the technical improvement of embodiment 1, in this embodiment, the height of the convex ring 111 is 5mm, and the width is 2mm.

The ring body 113 is arranged in the groove 112. The height of the convex ring 111 is increased to 5mm, which is convenient for installing the ring body 113. The ring body 113 made of hard material (such as polypropylene (PP) or polyethylene (PE)) is embedded in the groove 112, and the inner diameter of the ring body 113 is 1mm larger than the inner diameter of the convex ring 111. The enhanced convex ring 111 design significantly improves the stability of the rubber cap 100, and makes the fixing of the rubber cap 100 on the absorption bottle pipe 200 more reliable.
