Embodiment Construction
[0016] Such as Figure 1~Figure 2 A bottle cap shown includes a cover body 1. The cover body 1 is made of a medical material that can directly contact the liquid medicine. The middle part of the outer end surface of the cover body 1 is provided with a sealing gasket 4. The sealing gasket 4 has good molding processability and does not need vulcanization or refining. Glue, can be directly used for injection molding production, with better sealing performance and less puncture debris.
[0017] A thin puncture surface 6 is provided on the end surface of the sealing gasket 4 facing the inside of the cover, and the puncture surface 6 plays the role of the inner cover and directly contacts the liquid medicine. The end face of the sealing gasket 4 facing the outside of the cover is provided with puncture positioning holes 5, and there are two or three puncture positioning holes 5 for positioning the puncture positions. The bottle cap also includes a tearable film 2 covering the outer...

The invention discloses a bottle cover which comprises a cover body and a tearable membrane, wherein a sealing pad is arranged in the middle of the outer end surface of the cover body; a puncture surface is arranged on the end surface of the sealing pad, facing to the inner side of the cover; a puncture positioning hole is formed in the end surface of the sealing pad, facing to the outer side of the cover; the tearable membrane is used for covering the outer end surface of the cover body. The bottle cover adopting the structure has the following advantages: 1, the bottle cover is of an integral structure, the cover body can be used as both an inner cover and an outer cover, and the inner cover is not arranged, so that the cost is saved; 2, the bottle cover is simple in structure, simplified in production process, high in production efficiency and increased in production automation level; 3, the easily-tearable membrane structure is used, so that the problems of pull force and breakage of a pull ring are solved; 4, the sealing pad and the cover body are of the integral structure, so that the bottle cover is excellent in sealing property, better in needle holding effect and low in chip falling rate; 5, the bottle cover adopts a new production process and is formed in one step without semi-finished bottle cover storage, so that the pollution is alleviated and the convenience is provided for production management.
Description
technical field [0001] The invention relates to the field of transfusion medicine packaging, in particular to a bottle cap. Background technique [0002] With the development of our economy and the continuous improvement of people's medical level, higher requirements are put forward for the quality and technology of packaging materials. The technology of new large infusion packaging materials in my country is still in the research stage, and there are many technical bottlenecks that need to be further improved. Continuous improvement of product technology is the industry The needs of development are the needs of customers and the market, and it is the key to enhance the core competitiveness of enterprises. [0003] At present, during the use of traditional combined lid products, the problem of large tensile force often occurs, and the different direction of the tensile force of the guide groove of the circular pull ring has a great influence on the magnitude of the pull force...
