ABSTRACT:
An easy opening device specifically adapted to packaging of flexible film (3) having a line of weakness in tearing (4), the device being characterized in that it comprises a patch (5) that is flexible and substantially inextensible such as a label, a membrane, or a piece of film, which patch is applied to the outside face of the film (3) astride the line of weakness (4), and includes, over said line (4), separation means (6) for separating the patch (5) into two parts (7a, 7b), which means are normally inactive when the packaging (3) is closed and are made active by the user exerting sufficient traction; means (8) for bonding the film (3) to the patch (5) on either side of the line of weakness (4) and in register with the two parts (7a, 7b); and means (9) for enabling at least one of the two parts (7a, 7b) to be grasped manually so as to make it possible, once the separation means (6) have been activated, to move the two parts (7a, 7b) apart from each other and open the packaging.
