Envelope seal strip

摘要

A sealing strip on a release layer is disclosed. The release layer can include an envelope with walls cooperatively enclosing a pocket with an opening. The envelope can include a closure flap pivotable to close the envelope. A first location of the envelope can include a sealing strip releasably adhered to the envelope (or a release layer on the envelope). This sealing strip can be removable from the first location and placeable in a second location overlapping the closure flap in the closed position and an adjacent portion of an envelope wall. The sealing strip can include an adhesive capable of adhering to the closure flap and adjacent portion of the second wall for securing the closure flap in the closed position. The sealing strip can include a removable grasping tab connected by a weakened area. The sealing strip can be provided on a release layer independent of an envelope.

1. An envelope comprising:
first and second walls cooperatively enclosing a pocket space and defining therebetween an envelope opening to the pocket space; a closure flap having a free edge with a first adhesive layer adjacent thereto, the closure flap being associated with the first wall and pivotable with respect thereto to a closed position, the free edge is to define a border line between the closure flap and an adjacent portion of the second wall in the closed position; and a sealing strip having a detachable grasping portion, a first side, and a second side with a second adhesive layer, wherein, in an unsealed position, the sealing strip is releasably adhered to the envelope in a first location, and wherein, in the closed position, the first adhesive layer is to adhere to the second wall to form a first seal between the closure flap and the second wall to close the envelope opening and secure the closure flap, and the sealing strip is placed at a second location of the envelope overlapping the closure flap and an adjacent portion of the second wall to form a second seal between the closure flap and the second wall to secure the closure flap, at least a portion of the second seal is to overlap at least a portion of the first seal, wherein the sealing strip includes a weakened region dividing the sealing strip into a sealing portion and the grasping portion, the weakened region includes a line of perforations to enable the sealing portion to disconnect from the grasping portion, the sealing portion includes the second adhesive layer, the line of perforations enables the weakened region to hold the sealing and grasping portions together when the sealing strip is removed from the first adhesive layer, the line of perforations enables the weakened region to disconnect the sealing portion from the grasping portion when the sealing portion is adhered to the second wall and the outer surface of the flap.
