The device further comprises an abutment () and a knife arrangement (), wherein the at least one carrier member, in said pick-up position, is arranged for relative movement towards the abutment for engagement with a web () of interconnected opening devices arranged therebetween and for pick-up of one opening device; and wherein the knife arrangement is arranged to cooperate with the carrier member and the abutment or cutting out the opening device during the engagement of the carrier member with the web.

Device and method for attachment of an opening device on a flexible package

A resealable opening device for a flexible package () of collapsible type having a compartment defined by flexible walls (), comprising a thin-walled body () having a back surface () attachable on one of the flexible walls () of the package () in a dispensing portion () of the package, a first hinge joint () extending in a first direction (P) and connecting a first section () of the body () with a second section () of the body (), the thin-wall body () being intended to be arranged such that the first hinge joint () is arranged transversely to a dispensing direction (P) of the package, and a second hinge joint () extending in a second direction (P) crossing the first hinge joint (), wherein a locking member () is arranged for locking the first section () to the second section () when the first and second sections () are folded towards each other about the first hinge joint (). The thin-walled body () is further provided with a third hinge joint () extending in a third direction (P) crossing the first hinge joint () and arranged at a distance from the second hinge joint (). The thin-walled body is adaptable to an outwardly bulging shape change of the flexible wall () on which the device is intended to be attached.
