What constitutes a proper outer burial container?

A proper outer burial container is specifically defined as any container used for enclosing a casket for burial. This definition highlights that the primary function of the outer burial container is to provide structural support and protection to the casket, ensuring that it remains intact in the burial process. Outer burial containers are typically designed to prevent the ground from settling over time and may also protect the casket from elements like water and soil.

The emphasis on enclosing a casket distinguishes this option clearly from other types of containers or boxes that do not serve this specific purpose. For example, containers meant for storing ashes or decorative boxes intended for display are not designed to fulfill the functional requirements necessary for burial. Similarly, not all types of caskets comply with local regulations or standards regarding burial, making that option insufficient to describe a proper outer burial container.
