This burial container stands vertically, tapering from the top, where the head would be, down to the foot end, where cutting edges extend outward. This allows the container to bore its own hole as it's screwed into the ground.
As described in the patent, "The body is not affected by the motion as it is securely encapsulated within the container to stand proudly tall for all time."
The inventor claims his method will give a cemetery about three times more burial space. In addition, these containers "can be readily installed in ponds, corners and steeply sloped land."
The inventor is Donald E. Scruggs of Chino, California.
