ABSTRACT:
A stackable container comprises grooved upper and lower sides. The sides of the grooves are undercut. In the grooves of the lower sides are four hooks each having base which fits a groove, a flexible leg and a nose at the end of the leg to engage the undercut side of the groove in the upper side of an identical container. A supporting boss may be provided extending to above the leg, so that the container will be supported on the bosses.
