CA 2251787

The disclosure relates to an opening arrangement for packaging containers of the type which is manufactured from a flexible packaging laminate and includes a prefabricated outlet opening which is covered by a tear-off strip or so-called pull-tab. To facilitate pouring of the contents and permit reclosure of the packaging container, the container also displays a prefabricated pouring device (3) surrounding the outlet opening, the pouring device being applied on the outside of the packaging container and comprising a reclosable lid (8). In order to ensure satisfactory function and facilitate application of the pouring device onto the packaging container, the pull-tab (12) extends, according to the present invention, in beneath the pouring edge of the pouring device (3) and is fixedly sealed between the pouring device and the upper side of the packaging container (1). The fixedly sealed pan of the pull- tab (12) is disposed to be separated from the remainder of the pull-tab by means of a tear device (14) located in the pouring device (3), the tear device optionally including teeth (14') for tearing off the pull-tab in connection with the opening of the packaging container.

L'invention concerne un agencement d'ouverture destiné à des contenants d'emballage du type de ceux que l'on fabrique à partir d'un stratifié d'emballage flexible et qui comprennent une ouverture préfabriquée d'orifice de sortie, laquelle est recouverte d'une bande d'arrachage ou d'une languette de tirage. Afin de faciliter le versement du contenu et permettre la fermeture à nouveau du contenant, celui-ci est pourvu d'un dispositif verseur (3), lequel entoure ladite ouverture, est appliqué sur l'extérieur du contenant et comprend un couvercle (8) servant à fermer à nouveau le contenant. Afin d'offrir un fonctionnement satisfaisant et de faciliter l'application du dispositif verseur sur le contenant, la languette de tirage (12) s'étend, selon l'invention, sous le bord de versement du dispositif verseur (3) et elle est scellée fixement entre le dispositif verseur et le côté supérieur du contenant (1). Cette partie scellée de la languette (12) est disposée de manière à ce que l'on puisse séparer d'elle le reste de la languette, au moyen d'un élément d'arrachage (14) placé dans le dispositif verseur (3), cet élément d'arrachage comportant éventuellement des dents (14') servant à l'arrachage de la languette lors de l'ouverture du contenant.
