To provide security of attachment, between one container and another similar container adapted to be stacked on the top of the first container, each container has a keeper slot in one or more of its side walls adjacent the container floor and a spring leaf at the top of the container which may be bowed into either one of two stable positions. In one of these positions the leaf of one container registers with and locks within the keeper slot of a second similar container poised above the first container, and when the leaf is in the other of its stable positions it is disengaged from the keeper slot.

A stackable container furnished with interlocking means, comprising a floor and sidewall means upstanding therefrom to define an upwardly facing top aperture, a spring leaf mounted by its ends in an elongated opening extending generally parallel to said floor and adjacent the top edge portion of said sidewall means, said spring having a greater length than the opening in which it is mounted and depressible into either one of two stable positions, such that when the leaf is in its first position it over-lies the top aperture of the container, and in the second of said positions it is disposed clear of that aperture; and, a keeper hole adjacent the floor of said container; the arrangement being such that when the leaf is in its second position, the bottom of a second similar container is placeable within the top aperture of the first container, said leaf then being movable into its second position thereby to engage lockingly within the keeper hole of the second container.
