What term is used to describe the type of container that holds the casket for burial?

The term "Outer Burial Container" refers specifically to the type of container designed to hold a casket during burial. This container serves several important functions, such as providing support to the casket, protecting it from the elements, and preventing the grave from collapsing over time. Outer burial containers can come in various forms, including burial vaults and grave liners, and they are often required by cemetery regulations to ensure the integrity of the burial site.

Choosing this term highlights the specific role it plays in the burial process, distinguishing it from other types of containers related to funeral services. The other options do not accurately describe a container that is specifically designed for this purpose. For instance, an "Inner Burial Vault" would not be a commonly recognized term in the context of funeral services, and "Casket Case" and "Commemorative Box" refer to different concepts altogether rather than the external container used during burial. Therefore, understanding that the Outer Burial Container holds the casket and plays a critical role in the burial process marks it as the correct choice in this context.
