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.

Device for gripping a container preform, comprising an ejector acting as a tool for removing a spinner tip

A method for producing a marked container (), includes the following steps: a first step (E) of heating, beyond a glass transition temperature, at least one shape-changing portion of the thermoplastic material wall () of a preform (); and a second step (E) of forming the container by injecting a pressurized fluid into the body () of the preform () such as to change the shape of the heated portion of the wall () by stretching it; and a step (E) for marking the preform (), during which a mark () is provided on the shape-changing portion of the wall () such that the mark () is stretched at the same time as the wall (), during step (E) after forming.

A device () for serial treatment of hollow bodies including: a transport member (); a treatment rod () mounted slidably relative to the transport member (); controlled elements for moving each treatment rod () between a retracted position and an extended position in which the treatment rod () is intended for being inserted axially into the transported hollow body; wherein the controlled elements consist of an electric actuator () controlled by an electronic control unit () for stopping the treatment rod () in the extended position thereof. A method for serial treatment of preforms using the treatment device is also described.

Disclosed is a method for controlling a conveyor for conveying hollow bodies through a hollow-body heating station including: &#x2014;a heating tunnel defining a heating path, &#x2014;a conveyor including at least one travel track and shuttles capable of moving along the track while picking up at least one hollow body, the movement of each shuttle being controlled individually, &#x2014;a travel-track loading portion on which two consecutive shuttles move at a first predetermined input separation, and a travel-track unloading portion. Two consecutive shuttles moving on this unloading portion are spaced apart by a predetermined output separation that is different from the first input separation.

A method of forming a container (), includes: a partial expansion first step (E) during which the container () is filled with a pressurized blowing gas (G); a second step (E) of filling the container () during which the container () is filled with a filling liquid (L) that expels the blowing gas (G) through an outlet orifice (); and a third step (E) during which the contents of the container () are put under a pressure (HP) so as to make the container () conform to its final state (D), characterized in that, during the filling second step (E), the ratio of the flow rate of the incoming filling liquid (L) to the flow rate of the outgoing blowing gas (G) is controlled so as to allow the container () to continue to expand during this second step (E).

Method of forming a container by blowing and filling

A device () for injecting at least two pressurized fluids into the axially oriented neck () of a container () in the preform state in order to form a final container by deforming the container () by successively injecting a first pressurized fluid and then a second pressurized fluid, the device () including: a first duct for supplying a first pressurized fluid; a second duct () for supplying a second pressurized fluid; and an axial nozzle () into which the second supply duct () opens, the nozzle being intended to be placed concentrically inside the neck () with a radial gap (j) so as to allow the first pressurized fluid to be injected into the container () through the radial gap (j), characterized in that the second pressurized fluid used for forming the container () consists of an incompressible filling liquid.
