ABSTRACT:
An erectable container apparatus constructed from a substantially square blank of material for use in releasably storing various articles therewithin. The apparatus includes a plurality of side panels each having an inner edge attached to a base portion, an outer edge attached to a corresponding top flap member, and a left and right edge. The left and right edges are operably positioned at acute angles relative to the respective inner edges to which they intersect so as to provide substantially upright and inwardly sloping side panels upon articulation of the erectable container apparatus toward and into its fully articulated orientation. Locking elements are operably associated with at least two of the top flap members for releasably locking the erectable container apparatus in a fully erected orientation, as well as to releasably maintain the top flap members and the inwardly sloping side panels in a base and article covering orientation.
