What term describes a container designed for placement in the grave around the casket?

The term that describes a container designed for placement in the grave around the casket is "Outer Burial Container." This term encompasses various types of containers, including burial vaults and grave liners, that serve the primary purpose of providing structural support and protecting the casket from the weight of the earth above and from the elements.

An outer burial container is essential in ensuring that the casket does not collapse and that the grave retains its shape over time. By offering this protection, it also contributes to the overall integrity of the burial site. While both burial vaults and grave liners fall under this category, the broader term "Outer Burial Container" accurately describes any container used for this purpose in burial practices.

The other options represent specific types of outer burial containers. For example, a burial vault typically refers to a heavy-duty container often made of concrete or metal that provides the highest level of protection, while a grave liner offers less protection and often only serves as a basic covering. The term "grave box" is less commonly used and does not specifically refer to the practice of protecting caskets, thus making "Outer Burial Container" the most comprehensive and accurate choice.
