This resin-made container is provided with: a neck portion having a content inlet-outlet portion; a lateral surface portion connected to the neck portion; and a bottom portion that is disposed on the side opposite to the neck portion and that is connected to the lateral surface portion. The resin-made container is produced by a stretch blow molding process. The bottom portion has formed therein a bulge section that protrudes downward in the vertical direction. The bulge section is disposed in an eccentric region, of the bottom portion, positioned outside a region demarcated by perpendicularly projecting an opening plane of the inlet-outlet portion of the neck portion.

A blow molded synthetic resin bottle has a body and an elongated neck with the body providing a shoulder extending about the base of the neck. The neck has a first collar extending thereabout spaced adjacent the shoulder and at least one additional collar extending thereabout adjacent the upper end of the neck. The resin in the neck is substantially unoriented. To produce the bottle, a synthetic resin preform is injection molded with a generally tubular body and the elongated neck. This preform is placed in a blow mold cavity having a body receiving portion and a neck receiving portion that has a recess extending thereabout seating the first collar therein. The additional collar is disposed outwardly of the mold cavity and is disposed on the upper surface of the mold.

To sterilize a container during blow molding thereof.

After a preform (1) is put in a molding die (6), the molding die (6) is clamped, and a mist or gas of a sterilizer or a mixture thereof is blasted into the preform (1), a blow molding air is blasted into the preform (1) to expand the preform (1) into a container (2) as a finished product, and the used blow molding air is discharged from the container (2) to remove the sterilizer in the container (2).

A blow mold unit in which, when clamping first and second blow cavity split molds which are fixed to first and second fixing plates and bottom molds which are fixed to a bottom mold fixing plate, pressure receiving members fixed to the first and second fixing plates are brought into engagement with the bottom plate fixing plate. Guide plates are fixed to the bottom mold fixing plate, and guided members capable of being brought into abutment with the guide plates are supported by first and second pressure receiving plates. The bottom mold fixing plate includes a first connecting portion to be connected to a bottom mold opening/closing unit and a second connecting portion to be connected to a moving and biasing member.

A preform is heated, the heated preform is sealed in a sealing apparatus including a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the heated preform sealed in the molds is blow-molded into a bottle. Any molded bottle is removed if the mold surface temperature of the neck portion mold, the trunk portion mold and the bottom portion mold are outside of the predetermined temperature range. A sterilizer is blasted to any molded bottle not removed when the mold surface temperature of all of the molds is in the predetermined temperature range.

The system (1) comprises a male part (2), a female part (4), a driving piece (24) having a spool portion (26) provided with a radial bore (28), a driving member (30) moving radially inside the radial bore (28), a cavity (34) and a radial projection (40). The driving piece (24) moves in translation between a disconnected position of the male and female parts and a connected position of the male and female parts. The driving piece (24) comprises a piston (48) sliding in an activation chamber (14) under the effect of a pressing force. The piston (48) is attached to the spool portion (26) in such a way as to move the drive piece (24) to one of the positions from the connection position and disconnection position under the effect of the pressing force. The system (1) further comprises means of control for triggering the application of the pressing force on the piston (48).

The device used to hold workpieces is designed in a manner of tongs and is provided with two tong arms (45, 46). The tong arms are held by a tong base (47) and can be arranged at least in an open position and in a closed position. The tong base is held by a base element (48). The tong base is arranged on a transfer wheel, an opening movement of the tong arms being carried out by means of a movement component transverse to a radial direction of the transfer wheel. The first tong arm (45) extends on both sides of a central line of the tong base at least in some regions, said central line being oriented in a radial direction of the transfer wheel. A workpiece holding recess, which is spanned by the tong arms at least in some regions, is delimited by the second tong arm (46) only in a holding recess (68) region arranged on the outside in a radial direction of the transfer wheel relative to a holding recess transverse central line that runs transverse to the central line of the tong base.

A container obtained by blow-moulding a rolled tube. The container includes a body extending, according to a longitudinal axis, between a bottom and a neck made integrally in one-piece with the body. The body has, along a height according to the longitudinal axis, a wall having a thickness between 0.05 mm and 0.4 mm. The neck has, along the height according to the longitudinal axis, a wall having a thickness between 0.4 mm and 0.8 mm.
