ABSTRACT:
A protective envelope package is formed by folding an essentially flat blank along a midpoint and hinge area to form an essentially flat first panel and flat second panel. Upstanding from and along the top and bottom peripheral edges of the flat first panel are a plurality of annular receptacles. Upstanding from and along the top and bottom peripheral edges of the flat second panel are a like number of upstanding locking members, said upstanding locking members being adapted to engage said annular receptacles to maintain the envelope in a folded condition. A plurality of ribs disposed in a longitudinal and parallel conformation on the panels prevent compression of the flat first panel and flat second panel. The envelope package my be opened by exerting force downward on its peripheral edges so that the object retained therein is expelled without the user actually handling the object.
