CA 2343290

The present invention relates to packaging containers (10) for pourable food products, comprising a laminated, tubular packaging material with opposed end fin portions (11, 12) that have been produced by sealing and cutting a continuous packaging material web between consecutive packages. A line (14) of perforations extends across a corner of one of the end portions (11) to facilitate the opening of the container. The cut edge of the end fin portion (11) with the line (14) of perforations is provided with a bend (11d), so that a first segment (11b) of the cut edge extends more close to the product-filled part (13) of the container than a second segment (11c) of the cut edge. The second segment (11c) of the cut edge which is more distant from the product-filled part of the container than the first segment, forms a grip-tab (11a) for opening the perforated corner. The invention also relates to a knife apparatus and a method to produce the packaging container.

Cette invention a trait à des conditionnements (10) pour produits alimentaires liquides constitués d'un matériau d'empaquetage laminé tubulaire dont les extrémités opposées en forme d'ailette (11, 12) ont été formées par scellement et découpe d'une bande continue de matériau d'empaquetage entre ébauches successives de conditionnements. Une bande perforée (14) occupe un coin de l'une des extrémités (11) afin de faciliter l'ouverture du récipient. Le bord franc de cette extrémité (11) dans lequel a été ménagée la bande perforée (14) est ployé (11d), de sorte qu'un premier segment (11b) du bord franc se trouve plus rapproché de la partie du récipient remplie de produit (13) que ne l'est le second segment (11c) du même bord franc. Ce second segment (11c) plus éloigné de la partie du récipient remplie de produit que ne l'est le premier segment, constitue un onglet de saisie (11a) permettant l'ouverture du coin perforé. Cette invention concerne également un système de coupe et un procédé de production de ce type de conditionnement.
