Filed:

Jan 14, 1994

Appl. No.:

8/182307

Inventors:

Gordon E. Back - Wallingford PA

Assignee:

International Envelope Company, Inc. - Exton PA

International Classification:

B65D 8557

US Classification:

2063083

Abstract:

A mailer package is formed from a single sheet of foldable stock material and includes a pair of major planar parallel panels adjoining one another and joined together along a first fold of the material. A pair of panel tabs extending from opposing edges of one panel of the pair and are secured to opposing edge portions of the remaining panel of the pair. A closure flap extends from a fourth edge of the one panel and overlaps the remaining side of the package when closed, extending between the pair of panel tabs. The closure flap abuts the panel tab when the closure flap is closed with only pull tabs at the lateral sides of the closure flap extending above the panel tabs and the remainder of the closure flap. The closure flap extends more than halfway from the closure flap fold to the opposing first fold such that the pair of panel tabs and closure flap cover more than half of a major side of the closed mailer package.

Abstract:

A multiple-use, sealable flat envelope has a body of spunbonded olefin sheet. The body has one side edge with a mouth opening and a spunbonded olefin sheet closure flap extends continuously in one piece from the body on one side of the mouth opening. The flap has an inner surface facing and overlapping an edge portion of the body adjoining the mouth opening when the closure flap is folded back toward the body and fully extended over the mouth opening and against the body to close the mouth opening. Two adjoining but separate and spaced apart hot melt, pressure sensitive adhesive closures are provided on the spunbonded olefin sheet of the envelope proximal the mouth opening. One adhesive closure is located farther from the mouth opening than is the remaining adhesive closure. A line of openings through the closure flap extends entirely across the closure flap, the openings being spaced sufficiently closely to one another along the line that a tear force required to break bridges of the spunbonded olefin sheet of the closure flap between adjoining pairs of the openings of the line is less than a tear force required to separate either adhesive closure from the spunbonded olefin sheet supporting the adhesive closure. Where one release liner overlies each of the two adhesive closures, it is divided by a line of weakness extending across the release liner.
