Abstract
An envelope for two-way mailing having opposed front and rear panels secured together around three sides to provide an open edged pocket, a first flap to seal the pocket is foldably carried on the edge of the pocket by one panel. A resealing flap is carried on the edge of the pocket by the other panel. The resealing flap is inwardly folded upon its panel and disposed within the pocket during the first mailing. At least one spot of adhesive is employed to couple the resealing flap to an insert carried within the pocket. When the insert is pulled from the pocket, it automatically lifts the return flap from the pocket placing the envelope in its return mailing condition.
Claims27
An envelope for two-way mailing formed from a one piece blank having substantially rectangular front and rear panels interconnected along three edges to provide a pocket, and an insert for transmittal therein receivable within said pocket between the unconnected panel edges of the pocket comprising a first sealing flap carried by and integral with one of said unconnected edges, a second return sealing flap carried by and integral with the other unconnected edge, said second return sealing flap being folded inwardly along the unconnected panel edge of its supporting panel to extend within the pocket and overlie said supporting panel and means including at least one spot of adhesive to couple the return sealing flap to the insert whereby the inwardly folded return sealing flap is withdrawn from the pocket to its upright return sealing position when the insert is removed from the pocket.
