DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE PRESENT INVENTION
(14) The present invention is directed to provide body containment constructions, materials, and methods of use for bio-cremation processes. Preferably, the containment constructions of the present invention provide the functionality of liquid containment and also the functionality of body presentment for viewing purposes, if desired. In a basic construction, liquid containment is provided in a body containment construction that is sufficiently liquid impervious, allows for body transport by sufficient structural support, and is decomposable within the time period for a bio-cremation process. More preferably, the containment construction will dissolve or decompose within a normal procedural time period without leaving any component remaining from the containment construction.
(15) With reference to
(16) In
(17) For the supporting structural layer 14, a fabric layer is preferable, such as a woven or non-woven fabric that is made of organic, and more particularly, protein-based or starch-based fibers that will effectively decompose in an alkaline solution under bio-cremation conditions. Examples of protein-based fibers include wool, or silk that can be tightly woven in order to comply with the above structural and decomposable parameters as well as leathers, which also comply with structural and decomposable needs. The thickness or weight of the fabric is chosen based upon a balancing of the need for structural strength with the ability to decompose within the time constraints of a bio-cremation process. According to the present invention, a preferable thickness range for the structural fabric layer is based upon the strength requirements for the supporting layer primarily. With the use of decomposable structural layers, an alkaline hydrolysis process can easily decompose even very thick layers within the requisite time, so thickness is not an issue. Any structural material that is presently known or developed that will hydrolyze within the temperature, pressure and pH conditions of a bio-cremation process (discussed above) by way of alkaline hydrolysis is contemplated to be useful in accordance with the present invention. A preferred fabric comprises a wool gabardine weave that is tightly woven with a diagonal weave and of 100% pure virgin worsted wool. Such fabric is sufficiently durable for structure and retains a soft drape. Garbardine fabric is also naturally water repellant.
(18) It is also understood that the structural layer 14 may comprise any number of layers, so long as the above-noted requirements are met with respect to strength needs and decomposition needs. Such layers can be laminated with one another by any well-known technique or otherwise attached by stitching them together, or the layers can be simply overlayed one-to-another. Dark colors are preferred for the fabric to avoid visible staining, and non-toxic dyes are also preferred that do not bleed or stain when in contact with hot water. The structural layer 14 functions to provide the requisite support and strength requirements, as noted above, and preferably also provides durability, body cover appropriately, stain repellency, liquid absorption and an ability to be handled for transport, such as including handles or the like as also discussed herein. Other preferred constructions are discussed below.
(19) As to the liquid impermeable layer 12, water or liquid impermeability is important; however, breathability of the material layer is not an important factor. Resin films (whether of polymeric or oligomeric) of one mil in thickness or less are suitable for this purpose; however, compostable resin films of such thickness can be utilized in accordance with the present invention. For purposes of this invention, compostable means that such a resin layer is decomposable within an alkaline hydrolysis bio-cremation process as described within the Background section above. Suitable compostable plastic films include those that are starch-based, such as the Cardia Compostable BF films as are commercially available from Cardia Bioplastics of Blaine, Wash., U.S.A. A preferred film is a blown film resin identified as Cardia Compostable B-F film, which is a biodegradable and compostable resin material that is based on a blend of thermoplastic starch (TPS), biodegradable polyesters and natural plasticizers. This grade of resin is compatibilised to offer a high level of mechanical strength, elongation properties and toughness. The resin is derived from renewable resources including non-GMO corn starch which is an annually renewable resource. However, any liquid (water) impermeable resin or polymeric material that is presently known or developed that will hydrolyze within the temperature, pressure and pH conditions of a bio-cremation process (discussed above) by way of alkaline hydrolysis is contemplated to be useful in accordance with the present invention.
(20) Specifically, the liquid impermeable layer 12, such as a compostable resin material, whether provided as a film or a coating, should decompose along with a structural layer 14, such as comprising a wool or silk fabric, when subject to a mixture of water and an alkaline material such as potassium hydroxide, the mixture being at a pH of between 11 and 12 and at between 160 and 180 degrees celcius. The decomposition based upon alkaline hydrolysis of the body bag 10 along with all body tissues is expected within two to three hours under normal processing conditions. For purposes of the present invention, it has been found that by keeping the thickness of the liquid impermeable layer 12 below one mil, complete decomposition is easily accomplished under normal operating controlled conditions without any remaining residue present within a disposition chamber. The liquid impermeable layer preferably functions to not only provide for effective and adequate liquid containment, as discussed above, but also for biohazard containment, and as an odor barrier.
(21) The constructions according to the present invention may include multiple layers, as above with layers 12 and 14, which act together to provide desired functionality of a body bag 10 for bio-cremation. Any number of layers are contemplated, which layers can be overlaid without connection to one another, or may be partially connected together such as by stitches or the like, or may be fully laminated with one another. With a resin layer for liquid impermeability, as discussed above, that is also thermoplastic, a lamination process can be easily facilitated. Rolling a support fabric like wool or silk under heat and pressure with a thermoplastic and compostable resin layer will effectively produce a suitable laminated material. For example, a resin layer can be laminated to one side of a structural support layer by the application of sufficient heat and pressure. Or, a resin layer could be similarly laminated between structural support layers. Such a construction could allow for usage of multiple thinner structural support layers. Any number of layers are contemplated with the preference that all the layers will be effectively hydrolyzed within a bio-cremation process under conditions discussed above.
(22) Another aspect of the present invention is the provision of one or more closures to be effective to close the body containment bag 10 and thus contain any liquids and allow for human body transport. In the embodiment of
(23) In accordance with the present invention, it is preferred that all materials of the body containment bag 10 completely decompose within the parameters of an alkaline hydrolysis bio-cremation process. It is, however, contemplated that other components could be provided that would be recovered after the bio-cremation process, much in the same manner as medical implants are recovered. For example, a closure could comprise one or more metal components or the like that can be recovered and potentially reused. With respect to effectively decomposable other components, such as could be used in making closures like a zipper, starch-based resins are also contemplated. Again, any material and component design that can effectively hydrolyze within the constraints of the bio-cremation process could be utilized. For a component, such as a zipper closure or otherwise, the components would need to be designed thin enough to decompose within the time period for bio-cremation. Resin made snaps, buttons, and other resealable zip-type closures, as well as others of similar nature are contemplated provided that they can be made thin enough or of a material that decomposes sufficiently rapidly to be useful in accordance with the present invention.

(27) It is noted that dimensions of the layers 12 and 14 themselves, as well as the dimensions of the various components such as pockets sizes and the like can be widely varied based upon applications. A standard disposition chamber or resonator provides an internal space that is about 80 inches long by about 29.5 inches wide. Any bag sizes that fit within such interior space and accommodate any body size are contemplated. With larger chamber space, bags could also increase if desired.

(35) It is also noted that with certain disposition chambers that are in commercial use, a head support is sometimes provided to more effectively dissolve internal organs of the head effectively and to prevent the head from bobbing within the container. The support is a cage that maintains the head in position for directing solution directly to the head. A bag design of the present invention, as described above, is further advantageous in that the body can go into the chamber within the body bag 10 having the head uncovered to facilitate this process.

(38) Bag closure straps 212 preferably extend along a back surface of the bottom panel 202 at plural longitudinally space locations to provide closure to the bag 200 and to secure the body in position at both a shoulder position and an upper leg position. The ends of the straps 212 extend from the edges of the bottom and cover panels 202 and 204 so as to be tie-able to one another for this purpose. Any number of such straps 212 are contemplated for securing a body and providing structural support as desired.
(39) Structural support is further strategically provided by a pair of edge strips 214 and preferably a further pair of criss-cross strips 216 as shown. Ends of these strips can be connected with one another, such as by stitching, adhesive, or thermal bonding for creating loop carry handles 218 at each corner. The result is a body containment bag 200 that is effective for support and transport along with liquid containment and that is usable with a bio-cremation process as discussed above. Controlling the thickness of the reinforcing structural material, especially at areas of multiple overlaps is needed to make sure there is fully decomposition of the bag 200 within the time constraints of an alkaline hydrolysis process.
(40)
(41) It is contemplated that many variations can be made to constructions of body containment bags in accordance with the present invention. Many different cover and flap arrangements are contemplated with any number of panels with the basic aspect of providing liquid containment as desired and to provide structural support for body transport. Arrangements for body presentation can be made based upon different cover panel shapes, sizes and designs as well.
