Abstract
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.

A machine for forming and filling successive containers from preforms in successive molds with liquid, the machine comprising at least a first closed loop, and a plurality of holders, each holder being configured to hold a neck of a preform or of a formed and filled container, the holders being distributed along the first closed loop, the machine further comprising a conveyor configured to convey the holders along the first closed loop in a conveying direction, the first closed loop including a forming area along which each holder circulating in the forming area is integrated in a forming station, the forming station including a mold receiving a preform held by the holder, and an injector configured to inject a liquid inside the preform held by the holder such that the preform held by the holder is shaped into a container, the first closed loop including a first straight portion extending rectilinearly and a first circular portion upstream of the first straight portion, the forming area including the first circular portion.
A method for forming and filling containers, the method comprising the following steps:
- providing a machine for forming and filling containers having at least a first closed loop and a plurality of holders, each holder being configured to hold a neck of a preform or of a formed and filled container, the holders being distributed along the first closed loop, the machine further including a conveyor configured to convey the holders along the first closed loop in a conveying direction, the first closed loop including a forming area along which each holder circulating in the forming area is integrated in a forming station, the forming station including a mold receiving a preform held by the holder and an injector configured to inject a liquid inside the preform held by the holder such that the preform held by the holder is shaped into a container, the first closed loop including at least one straight portion extending rectilinearly and a first circular portion upstream of the first straight portion, the forming area including the first circular portion;
- feeding successive preforms to successive ones of the holders, such that each holder holds a preform by its neck;
- circulating the successive holders holding the preforms in the forming area of the machine, the preforms being placed in successive molds and the molds being coupled to the injectors for injecting a liquid inside the preforms placed in the molds to shape the preforms into containers in the forming area such that formed and filled containers are obtained at the end of the forming area,
- retrieving formed and filled containers at an exit area of the machine,
- wherein the formed and filled containers are circulated on the first straight portion of the first closed loop defined by the machine before being retrieved from the machine at the exit area.
