High density foam burial vault

DETAILED DESCRIPTION In a disclosed embodiment, a foam burial vault is formed entirely of high density closed-cell foam.
The foam is sufficiently rigid to protect the casket within the vault.
Further, the high density closed-cell foam is leakage resistant, such that water does not leak into the vault.
The foam preferably has a density of 8-30 pounds per cubic feet.
In another feature of the present invention, the burial vault is formed of substantially identical top and bottom halves that nest within each other.
Thus, a number of burial vaults can be stacked in a relatively small space.
Since the burial vaults are of relatively light weight due to their foam construction, they may be stored in relatively high stacks.
These and other features of the present invention can be best understood from the following specification and drawings, of which the following is a brief description.
