What is the name of a gasket-sealed container for use inside a casket or as a shipping case?

A gasket-sealed container designed for use inside a casket or as a shipping case is known as a Ziegler case. This type of case is specifically engineered to provide a hermetically sealed environment for the remains, preserving them during transport and ensuring they are protected from external elements. The design features a gasket that creates an airtight seal, which is crucial for maintaining the integrity of the body during the transit process.

In funeral practices, Ziegler cases are often utilized when bodies are being shipped over long distances or to different locations, ensuring compliance with regulations regarding body transport. This kind of container is thus integral to the mortuary profession, addressing both health and legal requirements associated with the handling of deceased individuals.

Other options do not serve the same specific purpose. An air tray, for instance, is typically a shipping container used for caskets but lacks the gasket sealing that provides the same level of protection. An air pack is not a recognized container in the context of mortuary practices, and a metal vault refers to a different type of burial or storage method rather than a shipping or internal casket container. Therefore, the Ziegler case stands out as the correct answer due to its unique design and application in mortuary procedures.
