Abstract

Abstract The present box is designed to be formed into an erect container without the need for staples or tape to hold the container together. The container corners are formed by gusset panels. These gusset panels have locking tabs which are held in place by locking panels attached to the side panels. The locking panels are held in place by locking indentations or apertures on the front and rear panels which mate with second locking tabs in the locking panels. A container cover is also formed without the need of tape or staples to hold the cover elements together. The side cover panels have front interior panels which extend along the front edge of the container. The cover front wall wraps around the front interior panels and locking tabs on the interior panel of the front cover insert into apertures. The apertures are in a locking tab hinged to the upper edge of said interior front flap.
