This setting can save the usage quantity of the rubber stopper 215 and reduce the manufacturing cost of the bottle cap.
[0033] Referring to Figure 3 and Figure 4, a circular protrusion is formed at the bottom of the rubber stopper groove 214 to form a bottom groove handle 217, and a circular protrusion is formed at the top of the upper cavity 23 to form a top handle 24. The top handle 24 and the bottom groove handle 217 are arranged vertically aligned. The top handle 24 is integrally provided with the outer cover 2. Specifically, the top handle 24 is arranged around the needle opening 22. In this application, the two groove cylinder parts 211 are set to be the same. Therefore, for the convenience of processing and manufacturing, a bottom groove handle 217 is also opened at the bottom of the needle groove 218, and a top handle 24 is also opened at the top of the upper cavity 23 corresponding to the position of the needle groove 218. This does not represent the only limitation of this application. In actual operation, the bottom groove handle 217 may not be opened at the bottom of the needle groove 218, and the top handle 24 may not be opened at the top of the upper cavity 23 corresponding to the position of the needle groove 218 according to the actual situation.
[0034] Refer to Figure 3 and Figure 4 , annular grooves are formed at the top and bottom of the rubber stopper 215 to form fixing grooves 216. The fixing grooves 216 are opened near the outer edge of the rubber stopper 215. The top handle 24 and the bottom groove handle 217 are respectively inserted into the fixing grooves 216 to fix the rubber stopper 215, so that the middle part of the rubber stopper 215 is aligned towards the needle opening 22. The needle can pierce through the middle position of the rubber stopper 215 from the needle opening 22. The top handle 24 and the bottom groove handle 217 are inserted into the fixing grooves 216, which can surround the middle part of the rubber stopper 215, thus isolating and forming a closed space, which can play a sealing role and prevent the middle part of the rubber stopper 215 from being contaminated.
[0035] Refer to Figure 3, the connecting portion 212 includes a reinforcing plate 2121 and a connecting plate 2122. The connecting portion 212 and the drum portion 211 are integrally provided. The connecting plate 2122 is disposed between the two drum portions 211, and the connecting plate 2122 is integrally provided with the two drum portions 211 to fixedly connect the two drum portions 211. The reinforcing plate 2121 is disposed on two adjacent sides of the connecting plate 2122 along the length direction of the drum portion 211. Specifically, the connecting plate 2122 is integrally provided with the bottom of the drum portion 211 and the connecting plate 2122. The setting of the reinforcing plate 2121 can improve the connection strength of the two drum portions 211 and make the crimping member 21 not easily deformed. A welding rib 213 is further provided on the top of the crimping member 21. The welding rib 213 is fixedly disposed at the top positions of the drum portion 211 and the connecting plate 2122. The cross section of the welding rib 213 is triangular. The welding rib 213 is used to fix the crimping member 21. In the embodiment of the present application, the welding rib 213 is welded by ultrasonic waves and welded into the material of the outer cover 2, so as to fixedly dispose the crimping member 21 in the upper cavity 23. One end of the reinforcing plate 2121 away from the drum portion 211 can abut against the side wall of the upper cavity 23, thereby producing a sealing effect and isolating external pollution.
