The new invention, Edged non-horizontal burial containers (US patent 8,046,883 November 1, 2011) makes further progress towards time-and-space-saving vertical interment methods.
The device will not only cut the costs of those faced with the expenses of a burial, but will also be of interest to owners of graveyards – for, as the inventor points out :
“The future business of a cemetery is based not only on maintenance of filled graves, but on the number of empty grave sites remaining within the cemetery.”
