What best defines an outer burial container in funeral services?

An outer burial container is best defined as a protective container placed in the grave. This definition addresses the primary purpose of the outer burial container, which is to provide structural support and protection to the casket and its contents as well as to help prevent the soil from settling over time. This function is critical in maintaining the integrity of the burial site.

The outer burial container may also serve to protect the casket from the elements, groundwater, and other external factors that may cause deterioration. Typically, it can take the form of a burial vault or grave liner, both of which support the earth above while ensuring that the grave remains stable.

In contrast, other options such as a decorative display for the casket or a liner for decorative purposes do not accurately represent the primary function or purpose of an outer burial container. Additionally, a container for cremated remains refers specifically to urns and does not align with the concept of an outer burial container as defined in the context of traditional burials.
