Container assemblies with releasable locking feature

摘要

A container assembly comprises first and second containers. The first container includes a first body portion and a first rim. The first rim has a first plurality of ribs projecting generally upwardly therefrom such that first spaces are formed between adjacent ribs. The first rim has a generally convex shape. The second container includes a second body portion and a second rim. The second rim has a second plurality of ribs projecting generally downwardly therefrom such that second spaces are formed between adjacent ribs. The second rim has a generally concave shape. The second container is shaped substantially the same as the first container. The first and second rims have shapes that correspond with each other when locked. The first and second containers are adapted to be releasably lockable by fitting the first plurality of ribs into respective second spaces and fitting the second plurality of ribs into respective first spaces.
