Even when the filling rate is high, the surface temperature of molded bottles is kept at a certain temperature or higher, and the bottles can be adequately sterilized with a sterilizer.

A preform is heated, the heated preform is sealed in a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the preform sealed in the molds is blow-molded into a bottle. Any bottle is removed which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of any of which is outside the predetermined temperature range, and a sterilizer is blasted to any bottle for sterilization which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of all of which is in the predetermined temperature range.

A system (1) for producing thermoplastic material bottles (5), the system (1) comprising in sequence: an extruder (10); a molding apparatus (20) for producing preforms; a thermal conditioning apparatus (30) for thermally conditioning the preforms; a blowing apparatus (40) for producing bottles (5) from the preforms; a pulsed light irradiation apparatus (50, 55, 60, 70); an aseptic filling and capping apparatus (80).

A laser welding system is directed to simultaneously joining respective layers of a first bag and a second bag. The system includes a first film layer adjacent to a second film layer for forming the first bag, and a third film layer adjacent to a fourth film layer for forming the second bag, each layer of the plurality of film layers being made of a thermoplastic material that absorbs laser radiation having a wavelength of about 2 microns. A non-absorbing carrier film layer is positioned between the second film layer and the third film layer, the non-absorbing carrier film layer being made of a material that transmits substantially all energy of the laser radiation. A laser source applies the laser radiation toward portions of the plurality of film layers to be joined, forming the first bag generally simultaneously with the second bag.

A plunger pump, including: a tubular cylinder that has an internal space communicating with inlet and outlet flow paths; and a piston that is movable along an axis of the cylinder, wherein a head of the piston includes, on an outer peripheral surface thereof, a sealing portion that is slidable against an inner peripheral surface of the cylinder, which includes a body tubular portion wherein the head is arranged during normal use, and a cleaning tubular portion wherein the head is arranged during cleaning, an inner peripheral surface of the cleaning tubular portion has an inner diameter equal to that of an inner peripheral surface of the body tubular portion, the cleaning tubular portion includes, on the inner peripheral surface thereof, at least one cleaning liquid circulation groove that is configured by a through hole or recess, and the cleaning liquid circulation groove extends obliquely with respect to the axis.

A method of controlling a preform for stretch blow-moulding a container with an integrally formed handle; the preform comprising a body portion and the integrally formed handle; the preform transferred from a perform supply source to a blow moulding die for blowing the container; the method including the steps of passing the preform through a preform handle orientating apparatus, transferring the preform to a preform transportation system, maintaining orientation of the preform handle imposed by the perform handle orientating apparatus during transfer to the perform transportation system and transfer to the blow moulding die, rotating the preforms during transport along the transportation system past an array of preform heating elements while shielding the integrally formed handle from excessive exposure to the heating elements, transferring the preform from the transportation system to the blow moulding die, and wherein the handle comprises a loop of orientable material extending between an upper connection region and a lower connection region on the body portion of the preform; characterised in that the handle has a generally uniform cross section from proximate the lower connection region to a gradually widening cross section approaching the upper connection region; the cross section reaching and maintaining a maximum width proximate the upper connection region.

Even when the filling speed increases, the surface temperature of a molded bottle falls within a constant range, and a sterilizer adequately sterilizes the bottle.

A preform is heated, the heated preform is sealed in a mold, the preform sealed in the mold is blow-molded into a bottle, the surface temperatures of a neck portion, a body portion, and a bottom portion of the molded bottle are measured, and the mold temperatures of a neck portion, a body portion, and a bottom portion of the mold is so adjusted that the measured surface temperature of the bottle falls within a specified temperature range.
