EASY-OPENING ENVELOPES

摘要

An easy-opening envelope (2) comprises a front face, a rear face (4), a closure flap (6), and an opening strip; the front face having a plurality of edges at which the front face is connected to the rear face (4) or the closure flap (6); the opening strip extending along, and being attached to, a first one of said edges (12); and a further one of said edges adjacent to said first edge (12) being provided with a line of weakness (26) which extends inwardly from said further edge (20) but does not extend to any of the other of said edges, said line of weakness (26) being arranged so that a user can open the envelope by first grasping a portion of the envelope (2) between said line of weakness (26) and said first edge (12), and then pulling along the direction of said first edge (12) so that the envelope tears from said line of weakness (26) to said first edge (12) to form a tab (32) which separates from the rest of the envelope but remains attached to the opening strip, so that as the user pulls the tab (32), the opening strip tears open said first edge (12) of the envelope (2).
