Abstract
A removal element is superposed on and joined to the periphery of an aperture which is preformed or precut on one face of a bag constituting part of a Bag-in-Box package. A supporting framework is superposed on the removable element, certain edges of which framework, preferably two, approximately coincide with the edges of the removable part, while the other edges of the latter are covered by the body of the framework. A margined corner of the removable part is left free to be grasped by the user in order to initiate the detachment and the tearing of the removable part. In order to facilitate the tearing, notches are provided, which are formed on one edge of the removable part. The tearing proceeds along the edges of the framework which cover the removable part so as to uncover, partially or entirely, the preformed or precut aperture which is present on one face of the bag.
