Container made from one-piece blank

Carton apparatus formed from a one-piece blank, comprising:

• a floor;
• a first panel;
• a plurality of wall members coupled end-to-end, at least one wall member comprising a wall panel having a generally planar portion with a side edge extending between a pair of said wall members and the wall panel hingedly connected to the first panel along a wall-panel-fold-line;
• a lid panel;
• a locking flap comprising a stem portion depending from the lid panel and at least one ear member spaced from the lid panel and laterally extending from the stem portion, the ear member including a locking-flap-locking-edge generally facing toward the lid panel;
• hinge means hingedly connecting the lid panel to one of the wall members so as to mount the lid panel for movement toward and away from the wall-panel-fold-line to thereby move the locking flap toward and away from the wall panel;
• a retention tab having a free corner, struck out from the wall panel with cut line so as to be hingedly joined thereto and so as to have a retention-tab-locking-edge adjacent the free corner, a portion of the retention tab which includes at least the free corner being biased by folding of the first panel about the wall-panel-fold-line, for movement away from the plane of the wall panel planar portion to bring the retention-tab-locking-edge away from the wall panel for engagement with the locking-flap-locking-edge;
• and
• the locking-flap-locking-edge moved into engagement with the retention-tab-locking-edge as the lid panel is moved toward the wall-panel-fold-line.
