The invention relates to a preform intended for forming containers by blow molding or stretch-blow molding, the preform being made of plastic material including at least one additive giving the plastic material the property of at least partially filtering the visible light spectrum, the preform comprising a wall forming a hollow body, said one or more additive(s) giving the plastic material the property of at least partially allowing the passage of light in the infrared spectrum.

Apparatus for producing containers, and in particular beverage containers, having a heating device configured to heat plastic parisons, having at least one first transport device, which transports the plastic parisons along a predetermined transport path, a sterilization device configured to sterilize the plastic parisons, and a forming device arranged downstream of the sterilization device, as seen in a transporting direction of the plastic parisons, and configured to form the plastic parisons into plastic containers by the application of a free-flowing medium, wherein said forming device has a transport chamber within which the plastic parisons are transported. The apparatus has an application device configured to apply a free-flowing sterilization medium, at least temporarily, to the transport chamber.

The apparatus for manufacturing a resin container includes a heating unit configured to heat a preform using heaters and, a blow molding unit configured to blow-mold the preform that has been heated, accumulators that are connected to the blow molding unit and for storing a pressurized gas to be used for blow molding, and a connection pipe that connects the heating unit and the accumulators via an electrically driven valve, in which the electrically driven valve is closed when electric power is supplied, and is opened when electric power is not supplied to cause the gas in the accumulators to flow to the heating unit.

In a blow-molding apparatus, a cooling device and a heating device are each driven by being supplied with electricity of a predetermined voltage from a supply power source. The blow-molding apparatus comprises: a monitoring device configured to constantly monitor fluctuation of the predetermined voltage; and an output automatic control mechanism configured to, in a case where the predetermined voltage monitored by the monitoring device fluctuates beyond a normal range, automatically fluctuate an output of at least one of the heating device and the cooling device to keep the output in a certain range, thereby adjusting at least one of the preform temperature and the ambient temperature to fall within a normal temperature range.

The invention relates to a device for treating container blanks for a container treatment installation. The device comprises a furnace for heating the container blanks. A planar drive system has a base element and a plurality of movement devices for transporting the container blanks. The plurality of movement devices are movable independently from one another relative to the base element. The container blanks can be moved through the furnace by means of the plurality of movement devices.

A heat treatment device for a PET bottle preform with an integral handle includes an air-cooling knife, a heating furnace, and a transport mechanism. The air-cooling knife is disposed on an outlet side of the heating furnace, the bottle preform is transported into the heating furnace through the transport mechanism, heated in the heating furnace, and transported to the air-cooling knife, and the air-cooling knife jets airflow to and cools a lower end of a handle of the bottle preform, appropriately reducing the temperature at junction of the lower end of the handle and a bottle body so that a gentle transition between the temperature of the bottle body and the temperature of the handle is achieved, and the handle is not easily deformed after the bottle preform is blown, thereby effectively improving the quality of the bottle preform after blown.

The present application includes an injection molding step and a stretch blow molding step. The stretch blow molding step is configured to include: a first step in which preliminary blow air is introduced into a preform to stretch the preform in a state in which a stretching rod does not contact the bottom of the preform; a second step which is executed after the first step, and in which the preliminary blow air is introduced into the preform and the stretching rod is moved at a set speed and pressed against the bottom of the preform to stretch the preform; and a third step which is executed after the second step, and in which final blow air is introduced into the preform to stretch the preform.

A temperature adjustment device (2) for thermally conditioning preforms (10) made of a thermoplastic material for subsequent molding including a transport device based on the rotary principle for transporting the preforms along a transport path that has at least one section with two adjacent transport lanes (32, 34) for transporting the preforms in two adjacent rows. Heating elements (36) are arranged between the transport lanes for heating the preforms. Each heating element acts on preforms in both transport lanes. At least one compensation device (22, 22′, 23, 24) for compensating for temperature differences between the preforms is assigned to the two transport lanes, which exclusively or more strongly acts on preforms in one of the two transport lanes for adjusting their temperature. Also, a container manufacturing machine (1) for manufacturing containers (12) from preforms that includes a temperature adjustment device.
