Folder with lock wings

A file folder comprising:

• front and back covers both formed from a flat sheet of cover material, both covers having top and bottom edges and an outboard edge, and said front and back covers are delineated from each other at a linear spine formed by a fold in said flat sheet of material,
• pockets formed on both said front and back covers, said pockets both having closures at said outboard edges of the respective covers upon which they are formed and both pockets having mouth openings facing said spine and said pockets extend between and are secured to said top and bottom edges of the respective covers on which they are formed, and
• a pair of lock wings attached to said front and back covers at said spine and said lock wings are both formed of a stiff patch of material and have free portions each directed toward a different one of said pockets and said free portions are resiliently deflectable away from the respective cover to which each lock wing is attached to vary the distance of separation between said free portions of said lock wings and the respective cover to which each of said lock wings is attached.

A file folder formed of a sheet of cover material that is folded to define a linear spine that divides said sheet of cover material into opposing front and back covers both having outboard edges located remote from and parallel to said spine, and both covers have top and bottom edges perpendicular to and extending between said outboard edges and said spine,

• at least one of said covers has a pocket formed thereon with closures at said outboard edge and at said top and bottom edges of said cover on which said pocket is formed, said pocket having an open mouth facing said spine, and further comprising
• at least one lock wing formed of a stiff material and secured to said at least one of said covers and having a free portion directed towards said open mouth of said pocket, and said free portion of said at least one lock wing is resiliently deflectable outwardly from said cover to which said at least one lock wing is secured.
