One-piece corrugated container
First Claim
1. A container formed of a unitary blank of foldable paperboard comprising:
- (a) a central bottom panel substantially rectangular in outline and integrally connected to opposed end walls and opposed side walls to provide an upwardly facing opening,(b) corner gussets between each end wall and the side walls adjacent thereto with each said corner gusset being folded inwardly of the container along the inner surface of the end wall adjacent thereto,(c) upstanding projections carried by the free extremities of each of said corner gussets with said upstanding projections carried by the corner gussets adjacent each end wall overlapping each other,(d) an end flap member on each end wall folded inwardly of the container and along the inner surface of the corner gussets adjacent thereto,(e) there being an elongated slot along the fold line of each said end flap member disposed to receive said upstanding projections carried by the corner gussets adjacent thereto,(f) opposed tabs on the free extremity of each said end flap member extending laterally away from each other with each tab being folded under the corner gusset adjacent thereto to lock the tab between said corner gusset adjacent thereto and the inner surface of the end wall adjacent thereto,(g) side flap members on said side walls folded inwardly toward each other to define a top for the container and having upwardly folded flaps on the free extremities thereof extending alongside each other,(h) handle means carried by said upwardly folded flaps,(i) upwardly projecting tabs carried by the ends of each said upwardly folded flap, and(j) there being aligned slots in said upstanding overlapping projections carried by said corner gussets receiving said upwardly projecting tabs carried by said upwardly folded flaps.

Abstract
A container formed of a unitary blank of foldable paperboard has a bottom panel generally rectangular in outline which is integrally connected to opposed end walls and side walls to provide an upwardly facing opening. Corner gussets between each end wall and the adjacent side wall are folded inwardly alongside the adjacent side wall with the free extremeties of the gussets adjacent each end wall carrying upstanding projections which overlap each other. An end flap on each end wall is folded inwardly along the inner surface of the adjacent gussets and has a slot along its fold line for receiving the adjacent upstanding projections. Opposed tabs on each end flap extend away from each other and lock between the adjacent gusset and the inner surface of the adjacent end wall. Inwardly folded side flaps on the side walls define a top for the container and have upwardly folded flaps on the free extremities thereof which carry upwardly projecting end tabs which project through aligned slots in the upstanding projections carried by the corner gussets.
