Continuous envelope

Claim 1

A continuous form envelope blank system comprising a continuous web of flexible material, a plurality of longitudinally spaced transversely extending perforation lines defining a plurality of successive blanks, a longitudinally extending fold line in said web dividing each of said sections into a first panel and a second panel, said first panel having a score line delineating a front portion and a flap, said flap being further defined by angularly extending edges and by a perforation line, said second panel forming a back portion having an edge spaced from the adjacent transverse perforation line and defining an access opening, said web being adapted to be folded about said longitudinally extending fold line, adhesive zones on said panels adapted to cooperate each with the other to secure said first panel to said second panel to form a complete envelope, perforation lines disposed in limited spaced relation to said fold line to form marginal portions, and a plurality of longitudinally spaced pin feed holes in said marginal portions, marginal portions defined by perforation lines disposed at the outer side edges of said web, said outer marginal portions having pin feed holes to cooperate with said first-named pin feed holes to advance the web as required, at least one of said second named marginal portions being enlarged for reception of indicia.

Claim 8

A system of continuous envelopes comprising a continuous web of flexible material, a longitudinally extending fold line, a plurality of longitudinally spaced transversely extending perforation lines defining a series of adjacent blanks connected by said perforation lines, each of said blanks including a first panel and a second panel joined to said first panel by said fold line, said first panel having die-cut openings defined in part by edges extending angularly oppositely with respect to said fold line, a score line extending between said edges and cooperating with the adjacent transversely extending perforation line to delineate a flap, an adhesive zone on said flap, said score line further cooperating with the opposite transverse perforation line to delineate in part a front portion, adhesive zones at the side marginal edges of said first panel, said second panel embodying a back portion defined by an edge coincident with said adjacent transversely extending perforation line and by an edge defining a die-cut access opening, adhesive zones at the side marginal edges of said back portion and an adhesive zone at said edge coincident with said adjacent perforation line, the adhesive zones of said back portion being adapted to register with the adhesive zones of said front portion, each of said panels being provided with a perforation line delineating a marginal zone adjacent to said fold line, at least one of said last-named perforation lines defining an outer marginal strip.

Claim 9

A system of continuous envelopes comprising a continuous web of flexible material, a longitudinally extending fold line, a plurality of longitudinally spaced transversely extending perforation lines defining a series of adjacent blanks connected by said perforation lines, each of said blanks including a first panel and a second panel joined to said first panel by said fold line, said first panel having die-cut openings defined in part by edges extending angularly oppositely with respect to said fold line, a score line extending between said edges and cooperating with the adjacent transversely extending perforation line to delineate a flap, an adhesive zone on said flap, said score line further cooperating with the opposite transverse perforation line to delineate in part a front portion, adhesive zones at the side marginal edges of said first panel, said second panel embodying a back portion defined by an edge coincident with said adjacent transversely extending perforation line and by an edge defining a die-cut access opening, adhesive zones at the side marginal edges of said back portion and an adhesive zone at said edge coincident with said adjacent perforation line, the adhesive zones of said back portion being adapted to register with the adhesive zones of said front portion, each of said panels being provided with a perforation line delineating a marginal zone adjacent to said fold line, at least one of said last-named perforation lines defining an outer marginal strip.

Claim 10

A system of continuous envelopes comprising a continuous web of flexible material, a longitudinally extending fold line, a plurality of longitudinally spaced transversely extending perforation lines defining a series of adjacent blanks connected by said perforation lines, each of said blanks including a first panel and a second panel joined to said first panel by said fold line, said first panel having die-cut openings defined in part by edges extending angularly oppositely with respect to said fold line, a score line extending between said edges and cooperating with the adjacent transversely extending perforation line to delineate a flap, an adhesive zone on said flap, said score line further cooperating with the opposite transverse perforation line to delineate in part a front portion, adhesive zones at the side marginal edges of said first panel, said second panel embodying a back portion defined by an edge coincident with said adjacent transversely extending perforation line and by an edge defining a die-cut access opening, adhesive zones at the side marginal edges of said back portion and an adhesive zone at said edge coincident with said back portion being adapted to register with the adhesive zones of said front portion, an outwardly extending tab being formed at the outer side edge of said first panel, said tab being adapted to be folded onto said first panel and being adapted to receive an adhesive zone for cooperation with a corresponding adhesive zone at the marginal side edge of said second panel.

Claim 11

A system of continuous envelopes comprising a continuous web of flexible material, a longitudinally extending fold line, a plurality of longitudinally spaced transversely extending perforation lines defining a series of adjacent blanks connected by said perforation lines, each of said blanks including a first panel and a second panel joined to said first panel by said fold line, said first panel having die-cut openings defined in part by edges extending angularly oppositely with respect to said fold line, a score line extending between said edges and cooperating with the adjacent transversely extending perforation line to delineate a flap, an adhesive zone on said flap, said score line further cooperating with the opposite transverse perforation line to delineate in part a front portion, adhesive zones at the side marginal edges of said first panel, said second panel embodying a back portion defined by an edge coincident with said adjacent transversely extending perforation line and by an edge defining a die-cut access opening, adhesive zones at the side marginal edges of said back portion and an adhesive zone at said edge coincident with said back portion being adapted to register with the adhesive zones of said front portion, an outwardly extending tab being formed at the outer side edge of said first panel, said tab being adapted to be folded onto said first panel and being adapted to receive an adhesive zone for cooperation with a corresponding adhesive zone at the marginal side edge of said second panel.
