Patent ID: 8191763

Claim:
A reusable envelope, the reusable envelope comprising: a reusable envelope body and a reusable sealing flap, the reusable sealing flap comprising: a first flap portion proximal to the reusable envelope body and extending along the reusable envelope body for a length, the first flap portion comprising a first adhesive region and at least partially defined by a fold line connecting the reusable sealing flap to the reusable envelope body and a first line of weakness spaced apart from the fold line; a second flap portion extending from the first flap portion and distal from the reusable envelope body and extending along at least a portion of the length of the first flap portion, the second flap portion at least partially defined by the first line of weakness and a second line of weakness spaced apart from the first line of weakness wherein the second line of weakness extends partially across the reusable sealing flap; a third flap portion extending from the second flap portion and distal from the reusable envelope body and having a length extending along a length of the second flap portion that is less than the length of the second flap portion, the third flap portion comprising a second adhesive region extending substantially across the length of the third flap portion, the second adhesive region comprising a first end adjacent a first side edge of the reusable sealing flap and a second end adjacent second side edge of the reusable sealing flap the third flap portion at least partially defined by the second line of weakness and a distal edge of the reusable sealing flap; a tear strip within said second flap portion defined at least partially by said first and second lines of weakness; said first side edge comprising an arcuate contour, the arcuate contour comprising a first edge portion at least partially corresponding with said second flap portion and intersecting a second edge portion at least partially corresponding with said third flap portion at a vertex defining an angular turning point between said arcuate contour and said second edge portion and thereby defining an angular indentation along said first side edge; at least one bridge portion partially connecting the second and third flap portions of the reusable sealing flap and extending between said second line of weakness and said distal edge of the reusable sealing flap so said bridge portion is structurally capable of at least partially maintaining the connection between said second and third flap portions of said reusable sealing flap after said tear strip is at least partially removed from the reusable sealing flap while also providing a narrowed region that facilitates severing of said third flap portion from said second flap portion through said narrowed region.
