Abstract
Abstract A quick opening envelope is provided wherein the bottom flap of the envelope is longer than the top flap and has an upper edge parallel to the lower edge of the upper flap. The lower flap is attached to the side flaps by means of spaced adhesive spots so that the lower flap can be torn from the side flaps by inserting a finger between the top of the lower flap and the side flaps just below the top flap and tearing the bottom flap away from the side flaps at the glued spots so that substantially the entire contents of the envelope are visible. The opening of the envelope is accomplished without tearing it so that it can be reused for storage of the contents.

A quick opening envelope which can be opened easily so that all of the contents thereof are visible, said envelope comprising: a front panel having upper, lower and side edges and a center line intermediate of and parallel to said side edges; a pair of side flaps folded inwardly, respectively, front each of said side edges, each of said side flaps having an upper edge adjacent said upper edge of said front panel and a lower edge extending angularly from adjacent said lower edge of said front panel to a point along the center line of said front panel and spaced from the lower edge thereof, the lower edge of said respective side flaps forming a configuration to permit viewing of the contents of the envelope; an upper sealing flap folded down along the upper edge of said front panel and overlying a portion of said side flaps and having adhesive means at least extending across said center line for permanently sealing said upper flap to said side flaps; a bottom flap folded upwardly along said lower edge of said front panel and having edges which overlie said lower edges of said side flaps and having a top edge lying in the same plane as the remainder of said bottom flap which is spaced from said upper flap, said top edge being unattached to said side flaps; and adhesive spots spaced along said lower edges of said flaps attaching said edges of said bottom flap to said lower edges of said side flaps, said top edge of said bottom flap being free from said side flaps so that said envelope can be opened quickly by inserting a finger between said upper edge of said bottom flap and said side flaps to grasp said bottom flap and tearing said bottom flap away from said side flaps at said adhesive spots to expose the contents of said envelope for removal thereof.
