Disclosed is a method for producing at least one molded, filled and sealed container product (10) comprising at least the method steps listed below: extruding a hose (32) by means of an extrusion device (12) using supporting gas in vertical extrusion direction in a preforming position; sealing the hose (32) at its lower end and cutting it at its upper open end; transporting of the parison (22) thus cut to length by means of a gripper device (20) in linear transport direction transverse to the extrusion direction from the preforming position into an opened molding tool (18); transferring the parison (22) into the opened molding tool (18) by means of the gripper device (20) in a main forming position; sealing the molding tool (18) for further forming of the parison (22) by a pressure gradient; filling and sealing the parison (22); and returning the gripper device (20) to the preforming position for a repeated sequence of the above method steps

There is provided a cooling mold for cooling a resin preform that has a gate portion protruding outward from a center of a bottom portion, in which an accommodating space that accommodates the preform is formed in the cooling mold, a bottom region facing the bottom portion of the preform in the accommodating space has a shape following the bottom portion of the preform, and an air sucking hole for sucking air is formed in the bottom region at a position shifted from the center of the bottom portion of the preform.

Provided is a thermal conditioning method of preforms. The method includes heating each preform by transport along a heating path exposed to heating radiation with a determined production rate; transporting the preforms (in line along a diffusion path; transforming the preforms in forming units at the determined production rate. The diffusion path includes a final buffer section along which the preforms travel for an adjustable duration.

A resin container manufacturing device includes: an injection molding part configured to injection-mold a first number of bottomed resin preforms by using an injection molding mold including an injection core mold and an injection cavity mold; a temperature adjustment part including a housing member configured to receive and perform temperature adjustment on the preforms demolded from the injection core mold in a high-temperature state; and a blow molding part configured to receive the preforms from the temperature adjustment part and blow-mold the preforms into resin containers. The injection core mold is configured to reciprocate between an injection molding position and a demolding position of the preforms. The temperature adjustment part is configured to perform the temperature adjustment by dividing the preforms housed in the housing member into a third number of groups each including a second number of preforms smaller than the first number.

A plant for producing and treating containers includes a heating device having a plurality of heating elements for heating a preform transported through the heating device, a blow-molding machine downstream of the heating device for forming the preform into a container, and a container treatment machine downstream of the blow-molding machine for treating a container. The heating device, the blow-molding machine, and the container treatment machine are operable synchronously at different production speeds. The plant also includes a control unit which is configured to adjust a power of at least one of the heating elements depending upon a change in the production speed of the blow-molding machine or the container treatment machine such that a total heat quantity, supplied to a preform, in the heating device does not exceed a specified limit value.

A method for producing at least one molded, filled and sealed container product (10) includes at least the method steps of: extruding a hose (32) by an extrusion device (12) using supporting gas in vertical extrusion direction in a preforming position; sealing the hose (32) at its lower end and cutting it at its upper open end; cutting the parison (22) to length; transporting the cut parison by a gripper device (20) in linear transport direction transverse to the extrusion direction from the preforming position into an opened molding tool (18); transferring the parison (22) into the opened molding tool (18) by the gripper device (20) in a main forming position; sealing the molding tool (18) for further forming of the parison (22) by a pressure gradient; filling and sealing the parison (22); and returning the gripper device (20) to the preforming position for a repeated sequence of the above method steps.
