Envelope with integral seal strip
View Patent ↗An envelope having an envelope wall member including first and second envelope walls that cooperatively enclose a pocket space and define therebetween a pocket opening to the pocket space, the envelope wall including a surface that defines a recess and a sealing strip that includes an adhesive releasably adhering the strip to the envelope wall member within the recess. The adhesive is capable of adhering the strip to the envelope wall to seal the envelope closed.
1. An envelope, comprising:
an envelope wall member including first and second envelope walls connected at an envelope hinge, the first and second envelope walls cooperatively enclose a pocket space and define therebetween a pocket opening to the pocket space, the second envelope wall including
a first layer and a second layer connected at a second wall hinge, wherein the first layer includes an adhesive portion and a release portion and the second layer includes a surface that defines a recess which aligns with the release portion in response to the first layer being folded against the second layer by bending at the second wall hinge; and
a sealing strip that includes an adhesive releasably adhering the strip to the release portion located within the recess, the adhesive being capable of adhering the strip to the envelope wall member in a different location than the recess to seal the pocket opening closed.
2. The envelope of claim 1 , wherein the recess is defined on an outer surface of the envelope wall member and the first envelope wall is connected to the second layer at the envelope hinge.
3. The envelope of claim 1 , wherein the second layer of the envelope wall member includes the sealing strip.
4. The envelope of claim 3 , wherein the second layer of the envelope wall member includes a weakened region outlining the sealing strip to enable the sealing strip to be separated from a remainder of the envelope wall member by breaking the weakened region, the weakened region defining the recess.
5. The envelope of claim 4 , wherein the weakened region includes a line of perforations.
6. The envelope of claim 3 , wherein the second layer of the envelope wall includes a layer of material defining a cut line extending around the strip, separating the strip from the wall member and defining the recess.
7. The envelope of claim 1 , wherein the sealing strip is substantially coplanar with the envelope.
8. The envelope of claim 1 , wherein the strip and recess are substantially the same size and shape.
9. The envelope of claim 1 , wherein the release layer extends over substantially the entire recess.
10. The envelope of claim 1 , wherein:
the recess includes an opening extending completely through the second layer, such that the sealing strip is releasably adhered to the first layer.
11. The envelope of claim 10 , wherein the release layer extends over substantially the entire opening in the outer layer.
12. The envelope of claim 10 , wherein the first and second layers are adhered adjacent to and around the perimeter of the recess.
13. The envelope of claim 10 , wherein the envelope wall member is made of a single sheet of material that is folded and adhered to provide the first and second walls, including the first and second layers of the second wall.
14. The envelope of claim 1 , wherein the envelope wall member includes a closure flap pivotally attached to the first or second wall, wherein the flap has a closed position in which the flap closes the pocket opening and is sealable to the other of the first or second walls with the sealing strip.
15. The envelope of claim 14 , wherein the flap extends from the first wall adjacent the pocket opening.
16. An envelope, comprising:
a first envelope wall; and
second envelope wall that cooperates with the first envelope wall to enclose a pocket space and define a pocket opening to the pocket space, the second envelope wall comprising inner and outer layers affixed to each other, wherein the outer layer defines a wall opening over a portion of the inner wall layer, the inner and outer layers connected at a second wall hinge, with the inner wall having an adhesive portion and a release portion, wherein the wall opening aligns with the release portion in response to the inner layer being folded against the outer layer by bending at the second wall hinge; and
a sealing strip disposed within the wall opening and including an adhesive that releasably adheres the strip to the release portion when the outer layer is folded against the inner layer, the adhesive being capable of adhering the strip to at least one of the envelope walls in a different location than the wall opening to seal the pocket opening closed.
17. The envelope of claim 16 , wherein the sealing strip is formed from the outer layer, the outer layer including a separation line delineating the sealing strip to enable separation thereof from the remainder of the outer layer.
18. The envelope of claim 17 , wherein the separation line includes cut.
19. The envelope of claim 16 , wherein:
the envelope wall member includes a closure flap pivotally attached to the first or second wall, the flap having a closed position in which the flap closes the pocket opening; and
the sealing strip being adhereable over the flap and the other of the first or second walls with the sealing strip to retain the flap in the closed position.
20. The envelope of claim 19 , wherein the flap extends and is pivoted from the first wall adjacent the pocket opening.
21. The envelope of claim 16 , wherein the envelope is made from a single sheet of material folded and adhered to provide the first wall and the second wall inner and outer layers.
22. A method for making an envelope with first and second envelope walls, comprising:
folding a first sheet layer to a second sheet layer with the first and second sheet layers connected at a common hinge to form the second envelope wall, the first sheet layer including an adhesive, and the second sheet layer including a release material and an adhesive portion, each of which are in contact with the first sheet layer, the release material being in contact and releasably adhered to the adhesive and the adhesive portion being fixed to the first sheet layer;
affixing the first and second envelope walls together by folding the first and second envelope walls together at a common hinge to cooperatively enclose a pocket space and define therebetween a pocket opening to the pocket space; and
cutting the first sheet layer to provide a sealing strip separable therefrom and that includes the adhesive, the sealing strip releasably adhered to the release material, with the sealing strip and the release material being aligned by folding the first and second envelope walls together at the common hinge, the adhesive being capable of adhering the strip to at least one of the envelope walls in a different location than the release material in the recess to seal the pocket opening closed.
23. The method of claim 22 , further comprising forming the envelope from a sheet blank which provides the first wall, the first sheet and second sheet layers of the second wall, and a flap pivotable for closing the opening, wherein the adhesive is capable of adhering the strip to the flap and one of the envelope walls to retain the flap closed.
