Abstract
The present invention is directed to providing a sterile package (1, 1′) integrally housing a contents-pouring device (5, 5′) which has improved contents pourability and tamper evidence. According to the present invention, the sterile package (1, 1′) can be efficiently produced by adopting the following steps of: (1) disposing a parison (27) in a mold (32) for a plastic container main body, (2) blowing sterile air from a nozzle (24) inserted in the parison (27) to blow-mold the plastic container main body, (3) filling the plastic container main body (2) with contents through the nozzle (24) and retracting the nozzle (24), (4) inserting a contents-pouring device (5, 5′) in the parison located above the plastic container main body (2), (5) clamping a mold (31) for a protective case, and (6) forming a protective case (6) with the parison located above the container main body (2).
