Or one final screwing before you go completely.  A new U.S. patent was granted yesterday for the above “Easy Inter Burial Container.”  According to the patent application for the EIBC, the reasons for such a vessel are three-fold: space, time, and cash are all at a premium.

This invention relates to conserving land area and easy to install burial containers which can be pressed, agitated, screwed, self bored or by other means set into earth or other receiving materials and do not require a large amount of land area or a large pre-dug rectangular hole with subsequent refilling after the placement of the burial container.
