Quick opening envelope

摘要

A quick opening envelope which gives full access to its interior upon opening is disclosed. The envelope is formed from a blank constructed from a single sheet of flexible material having a plurality of fold lines defining a front panel, a back panel, two side flaps and a closure flap. The back panel is attached to marginal areas of the side flap by means of a releasable adhesive material and to a central tab portion of the closure flap by conventional adhesive material. The closure flap tab is defined by a V-shaped formation of die cut perforations, each of which includes a curved portion and a straight portion. The V-shaped formation of perforations enables neat and easy opening of the envelope by lifting to separate the tab from the closure panel and the back panel from the side panels.
