Claim:
A sheet construction comprising: a printable sheet having weakened separation lines forming at least a substantial portion of a perimeter of a separable envelope assembly; the separable envelope assembly including: (a) a central body portion; (b) a first side panel along a first side edge of the central body portion and separated therefrom by a first weakened fold line on the printable sheet, the first side panel including a first locking tab; (c) a second side panel along an opposing second side edge of the central body portion and separated therefrom by a second weakened fold line on the printable sheet, the second side panel including a second locking tab; (d) a bottom flap along a bottom edge of the central body portion and separated therefrom by a third weakened fold line on the printable sheet, the bottom flap including a first locking tab slot and a second locking tab slot; and (e) a top flap along a top edge of the central body portion and separated therefrom by a fourth weakened fold line on the printable sheet, the top flap including a folding tab; the weakened separation lines allowing the separable envelope assembly to be separated by a user from the rest of the printable sheet after the printable sheet has been passed through a printer or copier and desired indicia printed on the separable envelope assembly to form a separate envelope assembly; and the separate envelope assembly being configured and adapted such that: (1) the bottom flap can be folded up on the third weakened fold line towards the central body portion and to a folded-up position; (2) with the bottom flap in the folded-up position, the first and second side panels can be folded on the first and second weakened fold lines, respectively, towards the bottom flap and the first and second locking tabs can be inserted into the first and second slots, respectively, such that the central body portion, the bottom flap and the first and second side panels together define a pocket having an open top; and (3) the top flap can be folded on the fourth weakened fold line and the folding tab tucked into the pocket behind a top edge of the bottom flap into a pocket-closed position to thereby close the top of the open pocket and secure an article positioned therein and to allow the top flap to be later moved to an open position to allow the article to be removed from the pocket.
