A machine for producing a container from a preform having a body and a neck defining an inner cylindrical opening. The machine includes a container forming and filling station where the preform is placed in a mold having a molding cavity and a forming liquid is injected into the preform thereby forming and filling the container with a liquid. Prior to forming of the container, an extension device is attached to the neck of the preform thereby forming an assembly. The extension device includes a connection part for attaching to the preform and an extension part defining an inner opening extending in the continuity of the inner opening of the neck of the preform. The extension device remains attached to the neck of the preform at least during the forming and the filling of the container.

Extension device for the neck of a container formed in a machine for forming containers from preforms

A machine and method for forming containers from preforms. The machine includes a mold loading station for loading successive preforms into successive molds, each mold forming a mold cavity having the shape of the container to be produced. The machine also including a forming station for forming the containers by injecting a gaseous or liquid fluid into the preform contained in each mold in order to expand the preform such that each preform acquires the shape of the container defined by the mold cavity. In the machine, the mold loading station and the forming station are distinct from each other, and the machine further includes a transferring station arranged between the mold loading station and the forming station for transferring the successive molds containing the preforms from the mold loading station to the forming station.

Machine and method for forming containers from preforms carried by successive moulds

A machine for shaping from a preform and filling with liquid successive containers. The machine includes forming stations comprising a main station and an elementary station. The machine further includes a series of elementary stations moving along a first closed loop and a series of main stations moving along a second closed loop. The first closed loop and the second closed loop including at least one common part wherein the main stations are coupled with the elementary stations and a distinct part wherein the main stations are separated from the elementary stations.

Machine for forming and filling containers comprising a first closed loop and a second closed loop having a common part

A method for producing a container from a preform having a body and a neck defining an inner cylindrical opening. The method including the steps of placing the preform in a mold having a molding cavity, &#x2014;forming the container by injecting a forming fluid into the preform, and &#x2014;filling the container with a liquid. Prior to forming of the container, an extension device is attached to the neck of the preform. The extension device includes an extension part defining an inner opening extending in the continuity of the inner opening of the neck. The extension device remaining attached to the neck of the preform at least during the forming and the filling steps.

A rotary apparatus for hydraulic forming of shaped containers including a rotatable forming wheel having a central axis of rotation and a plane of rotation perpendicular to the axis of rotation. A plurality of forming stations is supported by the forming wheel. The forming stations are operable to expand a preform into a shaped container by forcing a liquid into the preform. The longitudinal axis of each forming station forms an angle with the plane of rotation of the forming wheel of less than 20&#xb0; while the preform is being expanded. The projection of the longitudinal axis of each forming stations onto the plane of rotation of the forming wheel forms an angle with the radial direction at the position of the forming station of less than 20&#xb0; while the preform is being expanded.

Rotary machine and method for hydraulic forming of shaped containers

A method for manufacturing plastic containers in which, for each container, a plastic preform containing air is supplied; the preform is heated at a preform temperature over the glass temperature of the preform material, the preform is inserted in a mold having a mold cavity; and the preform is expanded to a container having the shape of a mold cavity by a forming liquid. The method also includes, between steps (b) and (d), the injecting of a gaseous product into the preform containing air, wherein the gaseous product is absorbable by the forming liquid. The injection conditions of the gaseous product are selected such that the injected gaseous product expels the air out of the preform.

Method and machine for manufacturing plastic containers

A machine to shape from a preform and fill with liquid successive containers in successive molds. The machine defines a first closed loop and includes a plurality of holding devices adapted to hold a neck of a preform or of a container. The holding devices are distributed along the first closed loop and the machine further includes a conveyor adapted to convey the holding device along the first closed loop. The first closed loop including a forming area along which each holing device is integrated in a forming station. The first closed loop also including one straight portion extending substantially rectilinearly.

Machine for forming and filling containers comprising a stabilization area for stabilizing the liquid inside the containers

The invention relates to a mold for molding a hollow body from a preform, the mold defining a molding cavity having the shape of the a hollow body to be molded. The mold including a first part and a second part movable relative to each other between an opened configuration, wherein the preform can be loaded inside the molding cavity, and a closed configuration, wherein the molding cavity is formed. The mold further including a locking element arranged to maintain the mold in its closed configuration in a locked position of the mold. The locking element having at least a sleeve portion arranged around a portion of the first and second parts in the closed configuration such that the sleeve portion surrounds the portion of the first and second parts and prevents the mold from moving towards its open configuration in the locked position of the mold.

Mold for molding a hollow body from a preform and machine comprising such a mold

An injection device having an inlet, an outlet and a chamber extending between the inlet and the outlet. A piston divides the chamber into an upper chamber and a lower chamber. The piston is movable within the chamber and includes a body. The piston includes a shutter movable with respect to the body between a closed position, wherein the body and the shutter isolate the upper chamber from the lower chamber when the piston is moved in an injecting direction, and an open position, wherein the body and the shutter place the upper chamber in fluidic communication with the lower chamber when the piston is moved in a filling direction.

Injection device for injecting a product in a container or a preform

Centrifugal device () of the rotating bowl type for supplying preforms (), which are horizontally-laid and aligned, from preforms () received in bulk, comprising a rotating transport ring () delimited by a lateral guide () and a central rotary disc () in the same direction as the ring and with an axis () inclined relative to that of the ring; a mobile member () mounted on the lateral guide occupies, as a result of the actuating means (), an operational position in which the preforms () are forced to leave the ring; detection means () upstream of the mobile member detect an undesirable preform () on the ring and control actuating means for bringing the mobile member into its operational position for the ejection of the undesirable preform.
