Envelope seal strip
View Patent ↗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.
2. The envelope of claim 1 , wherein the grasping portion of the sealing strip is free of the adhesive layer of the sealing strip.
3. 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, 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,
wherein the weakened region, the sealing portion and the grasping portion are releasable together from the first adhesive layer as a single strip of tape by pulling on the grasping portion.
4. The envelope of claim 3 , wherein the first location is disposed on the envelope such that the sealing strip must be moved away from the first location for securing the closure flap to the second wall in the second position.
5. The envelope of claim 3 , wherein the second position crosses over the border line.
6. The envelope of claim 3 , wherein the second adhesive is configured for permanently adhering to the second location.
7. The envelope of claim 3 , further comprising a release layer on the first location configured for providing the releasable adhesion and allowing removal of the sealing strip.
8. The envelope of claim 3 , wherein the sealing strip comprises a tape with a layer of the second adhesive.
9. The envelope of claim 3 , wherein the weakened region is to facilitate manual separation of the sealing portion from the grasping portion.
10. The envelope of claim 3 , wherein the line of perforations extends across the sealing strip.
11. The envelope of claim 3 , wherein the grasping portion is smaller than the sealing portion.
12. The envelope of claim 3 , wherein the sealing strip is elongated in a longitudinal axis, and the weakened region extends laterally across the sealing strip.
13. The envelope of claim 3 , wherein the grasping portion includes instructions on how to disconnect the grasping portion from the sealing portion.
14. The envelope of claim 3 , wherein the sealing portion includes printed indicia on the side opposite the adhesive layer.
15. The envelope of claim 14 , wherein the printed indicia includes a postal address.
16. The envelope of claim 7 , wherein the release layer includes a wax layer.
17. The envelope of claim 7 , wherein the release layer is sprayed onto a base layer.
18. The envelope of claim 17 , wherein the base layer and the second wall form different parts of a common substrate.
19. The envelope of claim 3 , wherein the grasping portion extends from the sealing portion as an area of the sealing strip provided without the second adhesive layer associated with the sealing portion.
20. The envelope of claim 3 , wherein the sealing strip fully separates from the envelope between being placed in the first location and the second location.
