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.

Method for operating an apparatus for producing plastic preforms and plastic containers, comprising at least one injection moulding machine and one blow moulding machine, wherein the plastic preforms are injection moulded within the injection moulding machine and are formed into plastic containers within the blow moulding machine and are transported from the injection moulding machine to the blow moulding machine, wherein a heating device is arranged downstream of the injection moulding machine and the injection moulding machine and the blow moulding machine are coupled to one another. According to the invention, the plastic preforms produced in the injection moulding machine are transferred directly after production to a thermal preform storage, which holds the plastic preforms at a predetermined temperature and wherein a speed and/or at least one parameter of at least one subsequent treatment device can be changed.

First, a composite preform 70 including a preform 10a and a plastic member 40a in close contact with the outer surface of the preform 10a is made by preparing the preform 10a made of plastic material and arranging the plastic member 40a to surround the outer surface of the preform 10a. Subsequently, the composite preform 70 is heated and inserted in a blow molding die 50 and undergoes blow molding in the blow molding die 50, by which the preform 10a and the plastic member 40a of the composite preform 70 are inflated integrally and a composite container 10A is obtained.

A blow molding apparatus includes: a temperature adjusting unit configured to supply a preform with cooling air to perform a temperature adjustment of the preform, the preform having been inj ection-molded, having a bottomed shape and made of a resin; a blow molding unit configured to blow-mold the preform that has been subjected to a temperature adjustment with blow air, and configured to manufacture a container made of a resin; an air tank configured to supply the temperature adjusting unit with the cooling air; and a recovery unit configured to recover the blow air exhausted from the blow molding unit into the air tank.

A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.

A temperature adjusting unit of a blow molding apparatus includes: a first drive unit configured to drive a core mold, from which the cooling air is supplied, in a first direction; a second drive unit configured to drive a cavity mold that accommodates the preform in a second direction; a first lock portion configured to restrict a movement of the first drive unit in the second direction at a first position where the core mold is inserted into the preform; and a second lock portion configured to restrict a movement of the second drive unit in the first direction at a second position where the preform is accommodated in the cavity mold.

This method for manufacturing a resin container includes injection molding a plurality of preforms in an arrangement direction, a adjusting the temperature of the preforms, and molding containers from the preforms. The manufacturing method includes, between the injection molding and the temperature adjusting, changing the orientation of the preforms aligned in the arrangement direction to an orientation aligned in a conveying direction.
