Stackable plastic container has detachable hook-shaped tongues on out-turned edge to hold each container to one below

摘要

A stackable plastic container (2) such as a plant trough or pot has two or more detachable tongues (13) on its out-turned edge (3), each tongue ending in a hook (17) to grip the edge of the container below. The tongues can be solid and offset relative to the container's axes of symmetry so that the tongues on one container and not aligned with those on the adjacent one, or each tongue can have an aperture (20) which allows the tongue on one container to be inserted through the tongue of the next.
