What are “outer burial containers” and their purpose?

Outer burial containers, also known as grave liners or burial vaults, serve a vital role in the process of interment. Their primary purpose is to help preserve the grave site and protect the casket from the elements as well as from the weight of the earth above. These containers are designed to prevent the ground from settling around the casket, thereby maintaining the integrity of the grave. By doing so, they also contribute to the overall aesthetics of the burial site, ensuring that it remains undisturbed over time.

The construction of outer burial containers often involves durable materials that provide a barrier against water, soil, and other external factors. This added protection can be particularly important in areas where the soil may erode or shift significantly. Additionally, many cemeteries require the use of outer burial containers to maintain uniformity in the landscape and to uphold cemetery regulations.

Thus, answer B accurately captures the essential function of outer burial containers in the context of funeral service and burial practices.
