The invention concerns a device for handling preforms for heating units. The device includes a mandrel that defines a rotation axis of the preforms; a tip mounted at an end of the mandrel and having a part penetrating into the neck of the preforms; a rubbing contact rigidly connected to the tip; and a heatsink rigidly connected to the mandrel and intended to come into contact with the tip. The tip also includes a cooling part axially in line with the penetrating part. The cooling part includes at least one thermal exchange raised portion in contact with the surrounding air. Furthermore, the tip is mounted such that it can be mobile on the mandrel.

A container manufacturing plant (10) includes an air circuit (78) employing a recycling method that includes at least the successive steps of: extracting filtered air from an oven (26), after the air has been used in the latter, for the purpose of cooling at least one part of the preforms; treating the sterilizing agent present in the extracted air resulting from the sterilization of the preforms; and recycling the extracted and treated air to the industrial area (16) where the plant (10) is installed. An air recycling method is also described.

Provided is an apparatus for heating plastic parisons, including a transport device or transporter, which transports the plastic parisons at least in sections along a predefined transport path, wherein the transport device or transporter has a plurality of holding devices or holders for holding the plastic parisons, with a heating device or heaters for heating the plastic parisons at least at times, while they are being transported by the transport device or transporters, wherein the apparatus has at least one heat shielding device or heat shield which is suitable and intended to counteract the heating of mouth regions of the plastic parisons.

Provided is an apparatus for heating plastic preforms with a transport device which is suitable and intended for transporting the plastic preforms along a predetermined transport path, with at least one stationary arrange heating device which heats the plastic preforms transported along the transport path, wherein the heating device has at least one heating element which emits radiation which heats the plastic preforms and at least one focusing device which focuses the radiation emitted by the heating element onto predetermined regions of the plastic preforms to be heated, wherein a position of this focusing device is changeable.

Provided is an apparatus for forming plastic preforms into plastic containers, having a blow mould which forms a cavity within which the plastic preforms can be expanded to form the plastic containers, and having an application device which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, wherein the application device is placed against a mouth area of the plastic preforms in order to act upon these with the flowable medium. The application device forms at least one first flow channel for the flowable medium, which guides and/or directs at least a portion of the flowable medium to an inner wall of the mouth area in order to temper and, in particular, cool this inner wall.

The invention relates to a heating device (H) comprising a heating section (24) for thermally conditioning preforms (1) consisting of thermoplastic material, comprising an upper orifice portion (21) having an opening, a collar-like support ring (54) arranged below the orifice portion (21), and a bottom portion (56) closed at the lower end, to a temperature profile suitable for blowmolding, wherein the heating device (H) has transportation means (33) for the transportation of the preforms (1) along a transportation path (55) of the heating device (H), and wherein the transportation means (33) each bear at least one handling means (41) for holding and handling the preforms (1), wherein a radiation screen (52), which follows the transportation path of the preforms (1), and which has a recess (53) at least on one end face to partially enclose a preform (1) held in the handling means (41) adjoining the recess (53), is provided in an intermediate space between two handling means (41) each provided for handling a preform (1), wherein the radiation screen (52) is arranged such that a surface region of the radiation screen (52), viewed in the longitudinal direction of the preform (1), at least temporarily overlaps on its side facing away with the orifice portion (21) with a surface region of the support ring (54) during the transportation of the preforms (1).

An injection nozzle for cooling and providing counter pressure to a neck of a preform during a forming of a container from the preform. The injection nozzle includes a manifold that defines a receiving space into which the neck of the preform is received. A cavity is also defined in a part by an inner wall and an outer wall of the manifold and a plurality of ports are provided through the inner wall to communicate the cavity with the receiving space. When a cooling medium is received into the cavity, the cooling medium is directed through at least some of the ports toward the neck of the preform located within the receiving space.

An oven (10) for the heat treatment of preforms and a method for operating an air-cooling device (42) fitted to such an oven includes controlling elements (58) to vary the cooling air flow rate onto the body (18) and bottom (20) of the preforms (12) along the heating path.
