An open, round container with a handle is a bucket. You might take a bucket and shovel to the beach for making sand castles.
Buckets are usually made of metal or plastic, and are typically used to carry liquids. A dairy farmer might catch milk in a metal bucket, announcing at the end of the morning, "I got six buckets of milk!" The expression "to kick the bucket" means to die — this particular meaning might stem from the French buquet, "balance," a beam that was used for hanging slaughtered animals.
