Abstract

PURPOSE:To produce a plastic vessel sealed in sterile condition by a method in which a prison is covered with molds, and sterile air is supplied into the parison, thereby achieving blow molding, and then after the parison has been sealed in between a blow molded vessel part and a blow head, it is cut off. CONSTITUTION:Sterile air is discharged from an air nozzle 2 through a sterile filter, and resin is extruded from a blow head 1 in the state that molds 4A, 4B are opened, whereby a parison 3 is molded. Next, after the parison 3 has been molded into a prescribed length, the molds 4A, 4B are closed, and the parison 3 is received in a main cavity 5 and an auxiliary cavity 6, and then unnecessary part is cut off. Next, the air nozzle 2 is lowered, and sterile air is supplied into the parison 3 under high pressure from the air nozzle 2, whereby blow molding is achieved. Then the air nozzle 2 is lifted, and seal fitments 9, 9 pinch a narrow tabular part 3b and thus the tubular part is closely sealed. Simultaneously, the center of the sealed part is cut off.

えパリソン３に穴がおいていても。In addition, as shown in FIG. 1A, with the molds 4A and 4B open, the resin is extruded from the blow head l to form the parison 3.
form. At this time, the lower end of the parison 3 has been closed by the previous molding process, so outside air will not enter the inside of the parison 3 during molding of the parison 3, and the inside will not be contaminated with foreign particles. The amount of sterile air discharged from the air nozzle 2 is selected so that the inside of the parison 3 does not become under negative pressure. With this selection, even if there is a hole in parison 3.

外部の空気がパリソン３内に入ることがないので、好ま

As a result, sterile air that has passed through the sterile filter 19 is supplied at high pressure from the air nozzle 2 into the parison 3 in the molds 4A and 4B, and the blow molding is performed through zero or more operations to form the container as shown in FIG. 1B. A portion 3a and a thin tube portion 3b connected to the upper end thereof are formed.

The opening time of the valve SVt is set by a timer (not shown), and the valve Sv1 is closed when the inside of the container portion 3a becomes slightly positive pressure. Thereafter, the air nozzle 2 rises to the position shown in FIG. 1C, and then the collar seal fittings 9.9 on both sides of the thin tube portion 3b are advanced by the air cylinder 10.10 to sandwich and seal the thin tube portion 3b.

密封する。同時にそのシール部分の中央を切断する。Seal. At the same time, cut the center of the sealed part.

よい。In the above embodiment, the air nozzle 2 is configured to be movable up and down, but the air nozzle 2 is placed in the position shown in FIG. However, in that case, the flow of air may be obstructed by the unevenness of the thin tube portion 3b, and the time required for blow molding may become longer. If the air nozzle is configured to be movable up and down as in the embodiment shown in FIG. 2, this drawback can be avoided. Further, in the above embodiment, the seal fitting 9 is configured to perform cutting at the same time as sealing, but the cutting may be performed after removing from the mold.
