Some item containers can be carried in your backpack. Other item containers cannot. If you try to pick up a container that cannot be carried, you will see a message that says "you cannot take this item".

Fluid containers do not have an explicit capacity. They are either empty or they have a liquid in them.
Some liquid containers allow you to see the liquid that is inside them (Vial, Bucket, Trough, etc.), but some liquid containers do not change appearance when they have a liquid in them (Bottle, Brown Flask, Cup, etc).
