Which of the following best defines an outer burial container?

An outer burial container is defined as a container that is placed in the grave around the casket. This container serves several important functions, including providing support to the earth above the casket and helping to maintain the grave's structure after burial. Outer burial containers, which can include burial vaults or grave liners, are designed to protect the casket from the weight of soil and prevent the ground from settling over time.

Understanding this definition is crucial for those working in the funeral service industry, as it relates not only to the logistics of burial but also to compliance with state regulations around funerals and burials. The other choices refer to different elements related to funeral services but do not accurately define an outer burial container. For example, a decorative casket is used during services, an urn is specifically for cremated remains, and a temporary receptacle implies a short-term use before final disposition, which does not align with the purpose of an outer burial container.
