  • Patent number: 6345422
    Abstract: A combination vault and casket assembly constructed of a vacuum formed polystyrene material and incorporating ballast stabilization during underground interment. A body includes a bottom, first and second upwardly extending side walls and first and second interconnecting end walls within which are defined inwardly vacuum formed depressions and which define in combination an upwardly facing perimeter. An arcuately shaped lid includes a downwardly facing perimeter edge capable of being matingly engaged with the upwardly facing perimeter edge to secure the lid to the body. A substantially planar shaped platform base has an upper face and a lower face, the upper face being configured about an outer raised and perimeter edge to receive the bottom of the body in slidably resistive fashion. An interior canyon of the platform base further includes a plurality of individual raised surfaces defining upper projections and reverse faces of the projections define corresponding recessed surfaces within the lower face.

  • Patent number: 6250025
    Abstract: An assembleable repository tower for holding individual quantities of burial remains including a platform base and a first plurality of four upwardly extending and elongate members. Each of the first members further includes a webbed configuration defining an axially extending and substantially hollowed interior. A second plurality of elongate members are second to selected faces of first and second of the first plurality of members. Each of the second members are assembled with the first members so that the tower is of a specified height and establishes four upwardly extending sides. A plurality of niche members are engageable with each of the upwardly extending sides, each of the niche members including a plurality of receptacle portions recessed inwardly from the associated side and which are suitable for holding a quantity of burial remains.

  • Patent number: 5960524
    Abstract: A burial container assembly with a lid constructed of a top and a plurality of sides extending from the top and which defines a first shell having a hollowed interior and a downwardly facing perimeter edge. A base is likewise provided with a bottom and both side walls and end walls which extend from the bottom to establish an open interior and an upwardly facing perimeter edge and which in combination define a second shell with a likewise hollowed interior. The base is preferably provided as a rectangular shaped body with an outwardly extending ledge projecting around a perimeter of the body and around which are assembled a plurality of individual side/end pieces and corner pieces to establish the hollowed shell of the base.

  • Patent number: 4531266
    Abstract: A burial vault includes a lid and a box portion. Depending rests are attached to the exterior bottom face of the box portion, so as to permit easy transportation of the vault. In another preferred embodiment the vault lid has recesses on its exterior face, which correspond to and are engageable with these rests. In still another preferred embodiment, these rests are self-burying in the ground in order to firmly seat the vault during use.

  • Patent number: 4314390
    Abstract: A composite burial vault is provided having a hollow liner constructed of a synthetic plastic material which is filled with concrete. In constructing the burial vault, a liquid bonding agent is applied against the liner. The bonding agent can be either an adhesive or a solvent which acts upon the plastic material or a combination of the adhesive and the solvent. Before the bonding agent dries, aggregate is applied to the surface of the liner preferably by a flocking gun. Alternatively, the bonding agent and aggregate can be simultaneously sprayed against the liner. As the bonding agent dries, the aggregate is bonded to the liner either by the adhesive and/or by a portion of the aggregate partially embedding in the liner. Concrete is then poured between a mold and the treated surface of the liner where it forms a mechanical bond to the coarse aggregate coating on the liner. Reinforcement strips are provided to strengthen the corner edges of the liner.

  • Patent number: 4261083
    Abstract: A composite burial vault is provided having a hollow liner constructed of a synthetic plastic resinous material which is filled with concrete. In constructing the burial vault, the liner is constructed from thermosetting resinous material in any conventional method. While the liner is still wet, aggregate is applied to the surface of the liner by a flocking gun or the like. Concrete is then poured between a mold and the treated surface of the liner where it forms a mechanical bond to the coarse aggregate coating on the liner.
