[0002] The medical liquid needs to be strictly sealed before use, because the liquid is applied to the human body, so in order to prevent the liquid from contacting the air and form pollution before use, and to ensure the tightness of the liquid, the usual The medicine bottle will be sealed with tin foil before the cap is sealed to protect the liquid medicine. However, once it is used, it will also be exposed to the air and cause pollution. Therefore, it is also necessary to seal the bottle mouth after use. The traditional sealing method cannot directly It acts on the mouth of the bottle, which will affect the sealing effect and increase the production cost

Embodiment Construction
[0017] As shown in the figure, a self-sealing combined bottle cap includes a cover body 1 and a sealing plug 2; Extending downwards, it has an annular shape; the sealing plug 2 is located on the periphery of the sealing body 3, and cooperates with the sealing body 3 to form a detachable fixed connection;
[0018] The sealing plug 2 includes a transverse sealing section 4, a longitudinal matching section 5 and a sealing chassis 6; the transverse sealing section 4 is located on the inner upper side of the cover body 1 and conflicts with the cover body 1; The longitudinal fitting section 5 is located on the periphery of the sealing body 3 and matches with the sealing body 3; the sealing chassis is located below the longitudinal fitting section 5 and is matching with the sealing body 3 Corresponding to the lower part, and fixedly connected with the longitudinal matching section 5.
[0019] Further, the sealing plug 2 is made of elastic rubber material, the greater the pressing fo...

The invention provides a self-sealing combined type bottle cap. The self-sealing combined type bottle cap comprises a cap body and a sealing plug; a sealing body is arranged in the cap body, extends downwards along the inner wall of the cap body and is in an annular shape; and the sealing plug is located at the periphery of the sealing body and matched with the sealing body to form detachable fixed connection. According to the self-sealing combined type bottle cap, the purpose that the sealing plug compresses the upper end of the cap body is achieved through cooperation with a matching boss according to the position relation between a sealing boss and a sealing groove, a bottleneck can be effectively compressed when the bottle cap is screwed, and sealing is achieved; and in addition, the assembling type sealing plug can be independently machined, therefore, the production efficiency is improved, and the application range is wide.
Description
technical field [0001] The invention relates to a self-sealing combined bottle cap, in particular to a bottle cap used in a medical liquid bottle. Background technique [0002] The medical liquid needs to be strictly sealed before use, because the liquid is applied to the human body, so in order to prevent the liquid from contacting the air and form pollution before use, and to ensure the tightness of the liquid, the usual The medicine bottle will be sealed with tin foil before the cap is sealed to protect the liquid medicine. However, once it is used, it will also be exposed to the air and cause pollution. Therefore, it is also necessary to seal the bottle mouth after use. The traditional sealing method cannot directly It acts on the mouth of the bottle, which will affect the sealing effect and increase the production cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-sealing combined bottle cap, whic...
