Claim:
A device for opening hermetic flexible containers, comprising: a flexible strip configured to be applied to an internal surface of a wall of a container, said strip comprising: a tape-like thread extending along a longitudinal area of tearing of the strip; a tear tab defined by a dinking of the strip configured to enable, in use, pulling of said tear tab by means of a gripping tab defined by a cut of said wall of the container, said tear tab configured to cause tearing of the strip and the consequent controlled tearing of said wall of the container; said strip and said wall of the container made of heat-sealable material and heat-sealed to one another, with the exclusion of said gripping tab; the dinking that defines the tear tab of the strip staggered with respect to the dinking that defines the gripping tab of the wall of the container, wherein the dinking that defines said tear tab of the strip is hermetically separated from the dinking that defines said gripping tab of the wall of the container via an area of heat sealing between said strip and said wall of the container; and wherein said area of heat sealing is defined by a thin, substantially annular, localized heat-sealed line.
