Abstract: Described herein is a device for opening hermetic flexible containers, comprising a flexible strip heat-sealed to the internal surface of a wall of the container and incorporating a tape-like thread having a tear tab to cause tearing of the strip, and the consequent tearing of the wall of the container, via a gripping tab of said wall. The gripping tab and tear tab are staggered with respect to one another and hermetically isolated by a heat seal between the strip and the wall of the container.

Abstract: An opening and reclosing device for flexible containers, comprising a label having an adhesive face intended to be applied to a wall of the container in correspondence of a die-cut area thereof. The adhesive face is formed with two side-by-side sections the first of which is intended to detachably overlay the wall of the container along the die-cut area, and the second of which is constituted by a bi-adhesive strip which is detachable from the label and intended to permanently adhere to the wall of the container (1) in proximity of the die-cut area.

Abstract: An opening device for sealed flexible containers (1), comprising a label (5) having an adhesive face (6) intended to be adhesively applied to the inner face of a wall (3) of the container (1) and incorporating a substantially central longitudinal strip (7) having an initial portion (10) constituted by a gripper tongue (10). The wall (3) of the container (1) is formed with an aperture, either a hole (4) or a partial cut (24) delimiting on the container wall (3) a tearing wing (25), so as to allow the gripper tongue (10) of the label (5) to be pulled outwardly thus performing tear breakage of the label (5) and the consequent tearing of the wall (3) of the container (1).

Abstract: A sealed packet containing food products in pieces, particularly sweets and the like, has an adhesive strip applied in a partially detachable and reattachable manner to a wall of the packet in correspondence with a shaped cut therein, so as to achieve controlled tearing of the wall during the first detachment of the adhesive strip, in order to define an opening through which the products in the packet can be removed. The adhesive strip is transparent and an indicator is associated therewith to provide an indication of any fraudulent opening of the packet.
