Containers and container assemblies with releasable locking feature

A container assembly, comprising:

• a first container including a first continuous body portion and a first rim, the first rim encompassing and projecting laterally outwardly from the first body portion, the rim having a first plurality of ribs projecting generally upwardly therefrom such that first spaces are formed between adjacent ribs, the first plurality of upwardly-projecting ribs creating a first pattern that is generally normal to the direction of the first rim;
• and
