At least two-layer label for opening and closing packages and the use thereof
First Claim
1. An at least two-layer label (1) for opening and reclosing a flexible pack which has a precut opening, closed with a lid, having a base label (3) having a top side and an underside, and whose underside is furnished with a first adhesive layer, which optionally prior to the bonding of the label (1) is lined with a release paper or release film,In which base label (3) there is provided a section (31) whose connection to the rest of the base label (3) is weakened or severed, and which is adapted to be disposed above the lid of said pack, the top side of base label (3), other than section (31) being abhesively furnished, and optionally a segment at the edge of base label (3) being abhesively furnished, and having an outer label (2) having a top side and an underside whose underside is furnished with a second adhesive layer, by means of which the outer label (2) covers said weakened or severed section (31), and is bonded on the base label (3), the bond strength of the base label (3) on the base on which the label (1) is bonded being higher than the bond strength of the outer label (2) on the base label (3), and the bond strength between section (31) and outer label (2) being higher than the force needed to separate the lid in the pack, by means of the section (31) bonded thereon, from the pack,and also optionally having further, protective labels provided on the outer label (2).
