OPENING WITH TEAR-OFF FLAP CAPABLE OF BEING WIDENED AND CLOSED AGAIN

摘要

An opening with a tear-off flap is formed by the superposition of the gluing edges (1a, 2a, 3a, 4a) of a package made of a single cut-out piece and can be widened and closed again. The strips (6; 7, 10, 13) that may be folded back after the flap (1f, 9) is torn let free a widened opening (F) and have stops for maintaining them in a closed position secured by the tear-off flap (1f, 9) provided with lateral stops (11).
