Title
(EN) A METHOD AND A PACKAGING APPARATUS FOR FORMING SEALED PARTIALLY-FILLED PACKAGES
(FR) PROCÉDÉ ET APPAREIL D'EMBALLAGE PERMETTANT DE FORMER DES EMBALLAGES SCELLÉS PARTIELLEMENT REMPLIS
Abstract
(EN)
There is described a method for forming sealed partially-filled packages (2) filled with a pourable product comprising at least the steps of forming a tube (3) from a web (4) of packaging material, filling the pourable product into the tube (3) for forming a product column (8) within the tube (3), directing a sterile gas into the product column (8) for forming and/or maintaining a gas cushion (10) within the product column (8), and forming and transversally sealing the tube (3), for obtaining the packages (2) containing the pourable product and a gas space (11) formed from a defined volume of the sterile gas originating from the gas cushion (10).
(FR)
La présente invention concerne un procédé de formation d'emballages scellés partiellement remplis (2) remplis d'un produit versable comprenant au moins les étapes consistant à former un tube (3) à partir d'une bande (4) de matériau d'emballage, remplir le tube (3) avec le produit versable pour former une colonne de produit (8) à l'intérieur du tube (3), diriger un gaz stérile dans la colonne de produit (8) pour former et/ou maintenir un coussin de gaz (10) à l'intérieur de la colonne de produit (8), et former et sceller transversalement le tube (3), pour obtenir les emballages (2) contenant le produit versable et un espace de gaz (11) formé à partir d'un volume défini du gaz stérile provenant du coussin de gaz (10).
