Abstract
A blank is provided for making an insert that satisfies the USPS requirement that a flat-sized mail piece be uniformly thick so that any bumps, protrusions or other irregularities do not cause more than ¼″ variance in thickness. In one embodiment, when folded, the blank forms an insert with spacers about a quadrant that receives a good to be mailed. In other embodiments, when folded, the blank forms an insert with sleeves into which goods may be slid, or an insert with sleeves with closed ends and into which goods may be inserted into cutouts in the sleeves.

A blank for a flexible insert for a flat-sized flexible envelope, said blank comprising
- a main section having a pair of substantially rectangular components and a fold line separating said rectangular components;
- a first extension extending from one of said rectangular components, said extension having three sections, a first fold line between and separating an outermost section thereof from a middle section thereof, a first pair of parallel spaced apart fold lines between and separating said middle section from an innermost section thereof and a second pair of parallel spaced apart fold lines between and separating said innermost section from said one of said rectangular components;
- a second extension extending from one side of the other of said rectangular components, said second extension having three sections, a first fold line between and separating an outermost section thereof from a middle section thereof, a first pair of parallel spaced apart fold lines between and separating said middle section from an innermost section thereof and a second pair of parallel spaced apart fold lines between and separating said innermost section from said other of said rectangular components;
- and
- a third extension extending from an opposite side of said other of said rectangular components from said second extension, said third extension having three sections, a first fold line between and separating an outermost section thereof from a middle section thereof, a first pair of parallel spaced apart fold lines between and separating said middle section from an innermost section thereof and a second pair of parallel spaced apart fold lines between and separating said innermost section from said one of said rectangular components.
