ENVELOPE

摘要

An envelope in which an insert is nested comprises a sheet of material having given horizontal and vertical dimensions, the sheet having a first fold line parallel to and between the horizontal end edges thereby providing first and second parts of the sheet and a second fold line perpendicular to the first fold line. A window is provided in one of the parts of the sheet, and lines of adhesive are provided on the sheet along portions of the edges thereof. The arrangement is such that the first part of the sheet may be folded along the first fold line to overlie the second part of the sheet and then the overlaid parts of the sheet folded again along the second fold line to provide a compartment of the envelope in which the insert is be nested whereby the insert is prevented by the second fold from moving to the window and obscuring the view of an address through the window.
