ABSTRACT:
A box includes a base portion and a lid portion. The base portion has at least two lateral panels which are joined together at an angled corner, and a recess is provided between the lateral panels at the corner. The lid portion includes a closure panel from which a locking tab extends, the locking tab being adapted to engage the recess when the lid portion is closed against the base portion. The closure panel is capable of curvilinear deformation by finger pressure, so that the locking tab can be withdrawn from engagement in the recess, thus permitting the box to be opened.
