Abstract
Abstract A CASKET SEALED TO PREVENT MOISTURE FROM ENTERING ITS INTERIOR, AND THE METHOD OF ACCOMPLISHING THE SEALING. AT GRAVESIDE, THE CASKET IS PLACED IN AN ELONGATED BAG OF IMPERMEABLE, SHRINKABLE PLASTIC MATERIAL AND THE OPEN END OF THE BAG IS CLOSED. THE CASKET IS THEN LOWERED INTO A VAULT PREVIOUSLY POSITIONED IN THE EXCAVATION, AND A SUBSTANTIALLY AIRTIGHT COVER IS PLACED ON THE VALUE. THE COVER INCLUDES MEANS TO ENABLE THE AIR WITHIN THE VAULT TO BE HEATED IN A CONTROLLED MANNER AND THIS CAUSES THE PLASTIC MATERIAL IN WHICH THE CASKET IS ENCASED TO SHRINK INTO TIGHT SEALING ENGAGEMENT WITH THE CASKET.
