HOLDING APPARATUS WITH FOLDABLE TRIFOLD STRUCTURE

An apparatus having a flat foldable trifold structure is disclosed for holding printed materials, including mailable literature. In some implementations, the apparatus includes a foldable body having a first and second portion. The first portion is folded along a lateral axis of the foldable body. The first portion has a rectangular region defined by four points and four boundaries, where three of the boundaries define incisions in the first portion such that the remaining boundary is permitted to be folded relative to a remaining area of the first portion to define a second fold extending along the lateral axis. The second portion includes a base region and a protruding region which is folded relative to the base region to define a third fold extending along the lateral axis. When the first boundary is folded relative to the remaining area of the first portion, the third fold receives an end defined by the remaining boundary.
