A blow molding machine is subjected to a sterilizing treatment in a simple manner. A liquid sterilizer is filled into preforms of at least the same number as the number of spindles. In a heating unit that heats the preforms to a molding temperature, some of the liquid sterilizer is caused to diffuse, and blow air is blasted into preforms in which the liquid sterilizer remains to cause the liquid sterilizer to diffuse in a molding unit, and molded bottles are discharged.

In a method for manufacturing a resin container, in the adjusting the temperature of the preform, the preform is accommodated in a cavity mold, a refrigerant introduction member is inserted into the preform, the refrigerant introduction member including a first flow path and a second flow path which are different in introduction or discharge position of a refrigerant, the preform is cooled by bringing the preform into close contact with an inner wall of the cavity mold at a pressure of the refrigerant introduced from the refrigerant introduction member. When the preform is cooled, cooling is performed by switching between a first cooling blow for introducing the refrigerant from the first flow path and discharging the refrigerant from the second flow path and a second cooling blow for introducing the refrigerant from the second flow path and discharging the refrigerant from the first flow path.

Ways to produce a plurality of preform (5) temperature profiles are provided that employ systems having a first heating means, a second heating means, and a first transfer means. The a first heating means has a first preform (5) path, imparts a first temperature profile to a preform (5) passing through the first preform (5) path, and has a first dispensing means configured to selectively dispense the preform (5) passing through at least a portion of the first preform (5) path. The second heating means has a second preform (5) path, imparts a second temperature profile to a preform (5) passing through the second preform (5) path, and has a second dispensing means configured to selectively dispense the preform (5) passing through at least a portion of the second preform (5) path. The first transfer means selectively transfers a preform (5) between the first preform (5) path and the second preform (5) path.

The invention relates to a device for gripping a container preform having a base, a spindle which is mounted on the base, and an ejector at least partially surrounding the spindle. The spinner includes a spindle mounted such that it pivots in a sliding manner in relation to the base and a spinner tip removably fixed to the spindle. The ejector partially surrounds the spinner and is able to occupy a working position in which it is secured to the base. The spinner tip and the ejector are respectively provided with an imprint and a complementary counter-imprint. The ejector can be removed from the base and can occupy a tooling position in which the counterpart thereof cooperates with the cavity of the spinner tip so that they rotate together.

A plastic molding system comprises: dispensing, pre-shaping and shaping cells and a transport subsystem. The dispensing cell has a station for dispensing a dose of plastic feedstock. The pre-shaping and shaping cells each comprise a plurality of stations for shaping the workpiece into a preform shape and into a final shape, respectively. The transport subsystem advances a workpiece along a selected one of a plurality of process paths to form a molded article. Each of the plurality of process paths is defined by a combination of stations of the dispensing cell, the pre-shaping cell and the shaping cell.

A hollow article is molded in a state where an inner surface of a neck portion including an inner screw portion is held by an inner neck mold, and then, the hollow article is demolded from the inner neck mold by inserting an ejection rod into the hollow article to be engaged with an inner surface of the hollow article and rotating the hollow article together with the ejection rod.

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.

Provided is a method for heating plastic preforms, wherein the plastic parison are transported along a predetermined transport path and are heated during this transport, wherein at least one first heating section with at least one first heating element as well as at least one second heating section with at least one second heating element is arranged along the transport path, by a first temperature measuring device an actual temperature of the plastic preforms is measured in or before a start region of the transport path, and as a function of this actual temperature of the plastic preforms the at least one first heating element is controlled in such a way that the plastic preforms reach a predetermined target temperature after heating by this at least one first heating element.

A molding device suitable for performing at least one of injection molding of preforms and blow molding of the preforms includes a pitch changing device including: N holding units capable of holding the preforms and arranged at a predetermined pitch in a predetermined direction, N being inter equal to or larger than 2; a coupling unit coupling the holding units adjacent to each other such that the pitch is changeable; a drive unit configured to generate a predetermined drive force; and a drive force transmission unit configured to transmit the drive force to each of one end-side and the other end-side, in the predetermined direction, of the coupled N holding units. The one end-side and the other end-side are configured to be moved in the predetermined direction by the drive force to change the pitch.

Disclosed is a container treatment apparatus for transporting plastic containers and in particular plastic preforms along a predetermined transport path, wherein the container treatment apparatus has at least one transport device having a plurality of holding elements, wherein the transport device is a pitch distribution starwheel having a movement device configured to allow movement of the holding elements in at least two planes.
