Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
268 words
A side-seam envelope comprising: a front panel having upper and bottom edges and opposed side edges; a pair of opposed side seams, each side seam being integrally connected to the front panel along one of said side edges and being folded back to lie adjacent the front panel; a back panel having upper and bottom edges, the bottom edge of the back panel being integrally secured to the bottom edge of the front panel, the back panel being folded up to lie adjacent the front panel and being secured to each side seam along at least a portion of the side seam; a flap integrally secured to the front panel along the upper edge of the front panel, the flap having an adhesive strip adjacent its free bottom edge, the flap adapted to be folded back and secured to the back panel by said adhesive strip; a tab defined by the area between a tab die cut extending through the back panel and having two upwardly turned, free ends, the lowermost point on the tab die cut being spaced a short distance from the bottom edge of the back panel; and means defining a tear line cut through the back panel and extending upwardly from each free end of the die cut to at least the free bottom edge of the flap in its secured position, the tear line when fully torn dividing the back panel into a torn portion and a remaining portion, the adhesive portion of the flap in its secured position on the back panel terminating short of the remaining portion of the back panel.
Claim 2
Dependent Claim
268 words
A side-seam envelope comprising: a front panel having upper and bottom edges and opposed side edges; a pair of opposed side seams, each side seam being integrally connected to the front panel along one of said side edges and being folded back to lie adjacent the front panel; a back panel having upper and bottom edges, the bottom edge of the back panel being integrally secured to the bottom edge of the front panel, the back panel being folded up to lie adjacent the front panel and being secured to each side seam along at least a portion of the side seam; a flap integrally secured to the front panel along the upper edge of the front panel, the flap having an adhesive strip adjacent its free bottom edge, the flap adapted to be folded back and secured to the back panel by said adhesive strip; a tab defined by the area between a tab die cut extending through the back panel and having two upwardly turned, free ends, the lowermost point on the tab die cut being spaced a short distance from the bottom edge of the back panel; and means defining a tear line cut through the back panel and extending upwardly from each free end of the die cut to at least the free bottom edge of the flap in its secured position, the tear line when fully torn dividing the back panel into a torn portion and a remaining portion, the adhesive portion of the flap in its secured position on the back panel terminating short of the remaining portion of the back panel.
