PROBLEM TO BE SOLVED: To prevent shrink of multiple packaging moldings charged with liquid by extending a parison to a cavity surface by vacuum evacuating by vacuum evacuating the parison, then diffusing the air to bring the parison into contact with cavities of both sides, charging liquid and then releasing the air in a resin container from a gap. SOLUTION: An end of a liquid charging nozzle 25 becomes a double tube nozzle 9, which has a charging nozzle 9a and a clean air diffusing nozzle 9b. That is, charging liquid is supplied by the nozzle 9a into the parison 23, and clean air can be diffused from between the nozzle 9a and the nozzle 9b. Semicircular cutouts 14 are provided at a predetermined interval corresponding to the nozzle 9 on clamping surfaces of both clampers 14. In the case of press bonding the parison 23 to the nozzle 9, a small gap is generated. Thus, when the liquid it charged, the air in the container is released from the gap so that pressure does not extremely increase. |
