Zusammenfassung: | A thermoplastic cap having an annular skirt with external left-handed screw threads thereon and a lateral external frangible brim at a lower end of this cap. The cap fits over a dispensing outlet of a thermoplastic bottle and the brim is precision fused to the bottle to form a hermetically sealed container for sterile medical liquids. An annular jacking ring with internal left-handed threads screws onto the cap skirt to open the container by fracturing the cap at its laterally extending frangible brim. |
