ABSTRACT:
A portable container comprising primarily a single folded blank. Integral folded parts of the blank form a bottom, front and rear walls, gable-shaped end walls, and overlappable gable-shaped covers respectively integrally and hingedly connected to the upper edges of the front and rear walls and closable to form a gable roof. Gable-shaped rafters integral with and extending along the upper edges of the end walls reinforce the end walls and cooperate with a ceiling on one of the covers to brace the end walls. One cover is provided at its apex with a hand grip accessible through openings in that cover and a registering opening in the other. The container includes channels for an insert to be located behind a window opening in the front wall, such channels being formed by flaps forming part of the blank. A triple-layer floor and double thickness end walls provide strength, certain of the layers of the floor and the gable-shaped rafters being formed by flaps integral with inner and outer end wall panels.
