Abstract

An interment cylinder includes a tube for cremation urns and a lid with attachment hardware. The tube has a weighted structure or base and a flanged collar. The collar mouth accesses an interior of the tube. The lid conforms to the mouth and aligns with the flange. The attachment hardware is threaded through the flange and the lid to re-openably seal the tube. An interment apparatus includes an encasement body with a first face and one or more interment cylinders. The first face has lifting grips and the mouth of the tube is accessible from the first face. A method for interring cremains in a gravesite includes embedding the interment apparatus within a gravesite, using the lifting grips to manipulate the interment apparatus; loading the cremains into the tube; and installing the lid and attachment hardware to seal the tube. The cremains may be cremated, aquamated, resomated, and/or bio-cremains.

Claims (22)

1 . An interment apparatus comprising:

an interment cylinder, comprising:

a tube configured to accommodate a plurality of cremation urns, the tube having a base, a sidewall rising from the base, and a collar joined to the sidewall distal from the base, the collar having a flange extending radially therefrom, the collar forming a mouth for access to an interior of the tube;

a lid configured to conform to the mouth, wherein the lid is operative to re-openably seal the tube; and

attachment hardware operative to secure the lid to the tube; and

an encasement body having a first face, wherein the tube is embedded in the encasement body such that the mouth of the tube is accessible from the first face.

2 . The interment apparatus of claim 1 , wherein the base is a weighted base.

3 . The interment apparatus of claim 1 , wherein the interior of the tube is configured to accommodate a circular shape of the plurality of cremation urns.

4 . The interment apparatus of claim 1 , wherein the interior of the tube is configured to accommodate a non-circular shape of the plurality of cremation urns.

5 . The interment apparatus of claim 1 , wherein the encasement body is made from a material selected from the group consisting of: metal, concrete, hempcrete, self-healing concrete, ashcrete, fiber cement, ferrock, bamboo concrete, and any combination thereof.

6 . The interment apparatus of claim 1 , further comprising lifting grips disposed on the first face.

7 . A method of interring in a gravesite at least two cremains selected from the group consisting of cremated, aquamated, resomated, bio-cremains, and any combination thereof, the method comprising:

providing the interment apparatus of claim 1 ;

embedding the interment apparatus within the gravesite;

loading the at least two cremains into the tube; and

installing the lid and the attachment hardware to seal the tube.

8 . The method of claim 7 , wherein the steps of loading and installing occur before the step of embedding.

9 . The interment apparatus of claim 1 , further comprising a gasket positioned between the lid and the flange, wherein the attachment hardware compresses the gasket to form a watertight seal.

10 . The interment apparatus of claim 1 , wherein the tube is made from stainless steel.

11 . The interment apparatus of claim 1 , wherein the tube and collar are manufactured as a single piece by rotational molding.

12 . The interment apparatus of claim 2 , wherein the weighted base, the tube, and the collar are manufactured as a single piece by rotational molding.

13 . The interment apparatus of claim 1 , wherein the attachment hardware comprises bolts threaded through the flange and the lid.
