Abstract
A corrugated fiberboard shipping container for fresh produce the container having a tubular body, a bottom closure which is formed by four bottom flaps, and a re-openable and re-closable top closure at the top of the container. The top closure is formed by four top flaps, each top flap being folded inwardly with respect to the body panel to which it is attached to extend transversely therefrom. Each of an opposed pair of top flaps has a pair of spaced apart elongate slots therein which extend, respectively from the juncture of each such top flap with its body panel partly to the free edge thereof. Each of the other opposed pair of top flaps has a pair of spaced apart cuts therein extending from the free edge partly to the juncture of such top flap with its body panel. The cuts form a spaced apart pair of locking tabs in the free edge of each of the other opposed pair of top flaps with an intermediate tab therebetween. The locking tabs, which are non-hingedly joined to the portions of the flaps which are inward thereof, are received in locking engagement in the elongate slots of the other pair of top flaps.
