Container

A container can only contain something if the container is "appropriate" for the task. Eggs in a basket is containment, but that same basket wouldn't serve as a container for water or gas pressure.
There are exceptions to the rule, for example, a balloon can hold gas pressure in containment; However over time the balloon might deflate because the gas might slowly escape, thus not being a good container. Another example is a bucket may hold water, but heat may make the water convert to gas and evaporate. The bucket is excellent at holding water but not suitable for holding gas.
