ABSTRACT:
A document pressing envelope is constructed by providing first and second substantially rectangular sheets of transparent material and a strip of opaque material, each of the sheets having corresponding first, second, third and fourth edges. A strip of first adhesive material is disposed on a first major surface of the first sheet, adjacent to the first edge thereof. The strip of opaque material is placed on the first major surface of the first sheet, to substantially cover the strip of first adhesive material. Strips of second adhesive material are disposed on a first major surface of the second sheet, adjacent to the first, second and third edges thereof. The respective first major surfaces of the first and second sheets are placed in facing contact, so that the respective second and third edges of the sheets are substantially in alignment to define respective closed ends of the envelope. The first edge of the second sheet is in overlapping relationship with a first portion of the opaque strip so that the first portion of the opaque strip is sandwiched between the first and second sheets. A second portion of the opaque strip extends below the first edge of the second sheet to expose the second portion thereof. A portion of the first sheet extends beyond the fourth edge of the second sheet, opposite from the first edge thereof, to define a flap member. A flexible band having a third adhesive material is placed on the flap member.
