Description:
REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to U.S. Provisional Application Number 61/749,792, which was filed on Jan. 7, 2013, the contents of each of which are incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    This field of this invention relates generally to funeral products for the interment of cremated remains receptacles and, more particularly, to a single and multiply cinerary urns containing the cremated remains/ashes of one person and a burial container as a repository system for single or multiple cinerary urns. The burial system contains the individual cremated human or pet remains. 
       BACKGROUND OF THE INVENTION 
       [0003]    Many different frame constructions, depositories, memorial holders and columbarium storage systems have been devised for the interment of human cremated remains for memorialization purposes. Memorial urns have been designed for storing the cremated remains in a repository structure, such as a columbarium or within an individual&#39;s residence. Alternatively, ashes are placed in a garden at a crematoria, cemetery, or spread at sea or on land at a particular location. In such an instance, a burial urn is not necessary. Placing ashes in a garden at a crematorium or cemetery does not allow the ashes to be contained in any type of receptacle. This method does not provide a way to preserve the integrity of the ashes. 
         [0004]    However, there has always been a demand for unique or different ways of memorializing a deceased person. To my knowledge, none of these moralizing structures have involved the ability to arrange cinerary urns of individuals, couples or family members in a multi-urn burial container. A burial container is a container that houses the cinerary urns. The burial container maybe eliminated if a burial vault structure is required, which intern will house the cinerary urns. 
         [0005]    In the funeral industry cremation has become an accepted option for the interment of human remains. Currently, it is the custom that human remains may be stored in an urn, placed in a columbarium, scattered at a designated location or buried under customary policies or applicable statutes. 
         [0006]    In recent years many religions, including various Christian faiths have changed their position on cremation from historically discouragement to acceptance due to the growing reality of cost and space considerations for traditional cemetery burials. 
         [0007]    While the church has modified its position and has allowed Christians to select cremation as an option, many still choose the burial of cremated remains as a means of complying with traditional Christian preferences. 
         [0008]    Currently, some of the challenges incurred with the burial of cremated human remains are: First, it is very expensive since a burial plot must be purchased. Secondly, one does not generally have total control of the deceased&#39;s remains or the preferred burial site location or arrangement. Thirdly, one cannot with certainty, provide interment with a spouse, partner, children, parent or other loved one (cherished person). Finally, one cannot generally relocate the deceased&#39;s remains, at a future date, if so desired. 
       SUMMARY OF THE INVENTION 
       [0009]    An embodiment of the invention relates to a grave marker, with single or multiple apertures, cremated remains urns and container(s) for cremated remains urns. It may also incorporate a burial vault structure where desired or required by local laws, or cemetery rules and/or regulations. The invention enables the cremated remains to be interred conveniently and efficiently. 
         [0010]    Another embodiment of the invention is directed to a cremated remains remembrance and burial system that includes an urn, an urn lid, an urn enclosure and a headstone. 
         [0011]    The urn includes an enclosure with an opening, a first sealing mechanism and second sealing mechanism. The urn lid is capable of engaging the first sealing mechanism to substantially seal the enclosure. 
         [0012]    The urn enclosure has a recess formed therein that is adapted to receive the urn. The urn enclosure is adapted to engage the second sealing mechanism to retain the urn in engagement with the urn enclosure. 
         [0013]    The headstone has an opening formed therein that is adapted to receive at least a portion of the urn. The headstone is adapted to engage the second sealing mechanism to retain the urn in engagement with the headstone. 
         [0014]    Another embodiment is directed to a cremated remains remembrance and burial method. Cremated remains are placed in an urn having an enclosure that includes an opening, a first sealing mechanism and a second sealing mechanism. 
         [0015]    An urn lid is attached to the urn. The urn lid engages the first sealing mechanism to substantially seal the enclosure. The urn is placed in an urn enclosure. The urn enclosure has a recess formed therein that is adapted to receive the urn. The urn is retained in engagement with the urn enclosure by engaging the urn enclosure with the second sealing mechanism. A memorial service is conducted where persons view the urn enclosure. The urn is separated from the urn enclosure after the memorial service is completed. 
         [0016]    The urn is placed in an opening formed in a headstone. The opening is adapted to receive at least a portion of the urn. The urn is retained in engagement with the headstone by engaging the headstone with the second sealing mechanism.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0030]    An embodiment of the invention is directed to a cremated remains remembrance and burial system. This invention has been created to address these impediments by providing a burial system for the interment of the cremated human remains that allows for couples, families, relatives, or significant others to have their cinerary urns or ash capsule to be placed adjacent to each other in a burial container. 
         [0031]    This invention is time flexible in that the cremated remains in a cinerary urn or ash capsule can be inserted at any time and additional family member&#39;s cremated remain in a cinerary urn or ash capsules can be included at a future date. A cinerary urn will incorporate the ash capsule from this point on. 
         [0032]    In addition, the invention is cost efficient in that there are no significant expenses associated with the burial after the initial purchase and interment of the original cremated remains in the burial container. This arrangement assures a defined future site location for a spouse or additional family members or significant others. 
         [0033]    The cemetery burial plot location can be significantly smaller without the requirement to accommodate traditional casket and vault arrangement. Alternatively, a cemetery burial plot that is sized for use in conjunction with a conventional casket can instead be used with burying a large number of cremated remains using the concepts of the invention. In such situations, multiple headstones may be used to identify each of the cremated remains buried therein. 
         [0034]    As an alternative to using the cremated remains burial system for burying cremated remains in a conventional cemetery, it is possible to use the concepts for burying the cremated remains in other locations where such alternative burial locations is not prohibited by law or regulation. An example of one such alternative burial location is on private property or public lands. Such alternative burial locations may be used in conjunction with memorializing an aspect of the deceased person&#39;s life. 
         [0035]    Additionally, this invention provides a burial system for the interment of cremated human remains that is completely portable to permit convenient relocation of the cinerary urn or ash capsule and the burial container, if desired or required, at some future date. 
         [0036]    This burial system can provide a cinerary urn receptacle to contain the ashes of pets or other animals whose remains are desired to be preserved for sentimental reasons. To our knowledge, at present, no eminently suitable system exists. 
         [0037]      FIG. 1  depicts a cinerary urn  10  having a top lid  12  housed in the burial container  14 , or as an option contained in a burial vault  54 , if required. The cinerary urn  10  is depicted as a cylindrical (bottle shaped) container; however the size, shape and form of both the cinerary urn, the burial container, and if required burial vault, are variable. 
         [0038]    The burial container  14  resides inside the aperture  16  in the headstone  26  and, if required, the foundation pad and burial vault cover  56 . The burial container  14  is adhesively or mechanically fastened  18  to permanently bond to the headstone  26 . The top closure cover  24  is bonded with adhesive  18  to the headstone  26  to permanently seal off the aperture. 
         [0039]    The headstone  26  is leveled and attached to the vault cover  56  with an industrial grade commercially available water-tight leveling compound  28 . The burial vault cover  56  is attached to the burial vault  54  with leveling compound  28 . Surround grade  34  (ground) is envisioned to be at or near the top surface of the headstone  26 . 
         [0040]      FIGS. 2 and 3  illustrate an alternate burial container top closure cover. This section drawing depicts a cinerary urn  10  having a top lid  12  housed in the burial container  14 . The cinerary urn  10  is depicted as a cylindrical (bottle shape) container; however the size, shape, and form of the cinerary urn, burial container, and burial vault are variable. 
         [0041]    The burial container  14  resides inside and below the aperture  16  in the headstone  26  and the foundation pad or burial vault cover  56 . The burial container  14  is adhesively fastened with a water-proof adhesive  18  to bond to the headstone  26 . 
         [0042]    The cinerary urn  10  and the top lid  12  may be fabricated from a variety of materials using the concepts of the invention. The materials used to fabricate the cinerary urn  10  and the top lid  12  should resist corrosion, degradation and be substantially gas impermeable for an extended period of time. 
         [0043]    As used herein, extended period of time means not experiencing corrosion, degradation or becoming gas permeable for more than one year. In other embodiments, the cinerary urn  10  and the top lid  12  resist corrosion, degradation and becoming gas permeable for more than about  10  years. 
         [0044]    Examples of materials that exhibit these characteristics include concrete, metals, engineered plastics, fiberglass, carbon fiber, ceramics, stone, manufactured stone, or any other material from which buried containers are being constructed (or maybe developed and constructed). In certain situations, it is also possible to use relatively brittle materials such as glass and ceramic to fabricate the cinerary urn  10  and/or the top lid  12 . 
         [0045]    Text and/or images may be placed on at least one surface of the cinerary urn  10 . Such text and/or images may be used to identify the person whose cremated remains are placed in the cinerary urn. Alternatively or additionally, the text and/or image may be used to identify aspects of the person&#39;s life such as the date on which the person was born, the date on which the person died, relatives of the deceased person, the profession of the deceased person and hobbies of the deceased person. 
         [0046]    In certain embodiments, a threaded insert  22  is fastened with an adhesive  20  to the inside of burial container  14 . The threaded insert  22  may have a generally cylindrical configuration. The threaded insert may be fabricated from a variety of materials. One suitable type of material that may be used is non-ferrous material that resists degradation such as by oxidation or rusting. 
         [0047]    The burial container  14  with the threaded insert  22  may be closed off with a flexible gasket or water-proof sealing compound  32 , with threaded top closure cover  24 . The threaded top closure cover  24  would be secured to the threaded insert  22  to provide a weather tight and security/tamperproof top closure cover to the burial container  14 . 
         [0048]      FIG. 4  is an isometric view of the headstone  26  illustrating the top closure cover  24  that is screwed into the threaded insert  22  that is adhesively fixed into the burial container  14  all within the aperture opening  16  in the headstone  26 . The headstone rests on top of the burial vault cover  56  and the burial vault  54 . 
         [0049]    The top of the headstone is approximately at the elevation of the surround ground  34 . For clarity, cinerary urn  10  is not shown in this drawing.  FIGS. 2 and 3  headstones would be similar to  FIG. 4  with various sizes of burial containers or burial vaults located below the headstone  26  or the burial vault cover  56 . 
         [0050]    The burial container  14  may be modified to include only the top closure portion if the burial vault  54  and the vault cover  56  are installed and this arrangement is acceptable to the cemetery or burial site possessor. 
         [0051]      FIG. 5  illustrates a multiple cinerary urn burial container with a removable top closure cover  24  to facilitate the interment of cinerary urns at various times. This section drawing depicts a cinerary urn  10  having a top lid  12  housed in the burial container  14  or burial vault  54 . 
         [0052]    Cinerary urn  10  is depicted as a cylindrical (bottle shape) container. However, the size, shape, and form of the cinerary urn, burial container, and burial vault are variable. The burial container  14  resides inside the aperture  16  in the headstone  26  and the vault cover  54  and the burial vault  56 . The headstone  26  is leveled and attached to the vault cover  54  with an industrial grade commercially available water-tight leveling compound  28  which is attached to the burial vault  56  with the leveling compound  28 . 
         [0053]    The burial container  14  is adhesively or mechanically fastened  18  to bond to the headstone  26 . The threaded insert  22  is fastened with an adhesive  20  to the inside of burial container  14 . The burial container  14  with the threaded insert  22  is closed off with threaded top closure cover  24 . The threaded top closure cover  24  would be secured to the threaded insert  22  to provide a weather tight and security/tamperproof top closure cover to the burial container  14 . 
         [0054]      FIGS. 6 and 7  are section drawings illustrating a burial vault construction containing multiple cinerary urns. This section drawing depicts a cinerary urn  50  having a top lid  52  housed in the burial vault  54 . The cinerary urn  50  is depicted as a cylindrical vase shaped container. However the size, shape, and form of the cinerary urn, burial container, and burial vault are variable. The burial vault structure  54  with the vault cover  56  resides below the headstone  26 . 
         [0055]    An aperture  16  in the headstone  26  and the burial vault cover  56  provides for access to the burial vault through the headstone opening  16 . The threaded insert  22  is fastened such as with an adhesive  20  to the inside of headstone  26 . The headstone  26  with threaded insert  22  is closed off with threaded top closure cover  24 . 
         [0056]    The threaded top closure cover  24  would be secured to the threaded insert  22  to provide a weather tight and security/tamperproof top closure cover  24  to the headstone  26  and the burial vault  54 . 
         [0057]    The headstone  26  is leveled and attached to the burial vault cover  56  with such as with an industrial grade commercially available water tight leveling compound  28 . The threaded top closure cover  24  is sealed with a flexible gasket or weatherproof sealing compound material  32  to the headstone  26 . This configuration provides a weather tight security closure for the burial vault and cinerary urns while allowing for the additional interment of cinerary urns at future dates. 
         [0058]    The size of the burial capsule is sufficiently large to receive the predetermined number of urns which are generally cylindrical in shape and sized to contain approximately 50-300 cubic inches of ash. The urn would have a tight closing top lid to protect and contain the ash contents of the urn. Ideally, the urn-like containers should be water tight and air tight to preserve the remains in a dignified, memorialized environment. 
         [0059]    The cinerary urn would be placed in a vertical manner and remain generally upright. It is also possible to adapt the concepts of the invention to bury the cinerary urn in other orientations such as horizontal. 
         [0060]    The burial container would have a top aperture or opening to receive the urn(s) and would be fastened to a support plate which is a flat headstone, gravestone, or memorial plaque recessed into the earth to generally be at the level of the surrounding earth to accommodate cemetery lawn or ground maintenance. Alternately, the burial container could be placed above the surrounding earth, if so desired. 
         [0061]    The headstone/support plate would be fabricated from materials such as stone, manufactured stone, concrete, metal, engineering grade plastics, or a combination of materials capable of resisting deterioration over an appreciable period of time for the intended use. The headstone/support plate would be capable of bearing an inscription identifying the deceased individual, pet or animal at the discretion of the owner or survivor. 
         [0062]    The headstone/support plate functions primarily to locate the burial system on the ground surface and to provide adequate support for the burial container assembly that is fastened and suspended directly underneath it in a buried condition or alternatively housed in the burial vault. The headstone/support plate may be constructed in any geometric shape such as rectangular, circular, oval or other free form shape with sufficient surface area to support the weight of the burial container system. 
         [0063]    The burial container would be mechanically or adhesively attached to the headstone flat support plate. The aperture or opening in the headstone flat support plate would contain a threaded insert adhesively attached to the flat support plate. This insert would receive a threaded connector that provides a weather tight and security/tamperproof top closure cover to the burial container. 
         [0064]    Alternately, flanges attached to the sides of the burial container, twisted in either direction against the underside of the headstone, would provide weather resistances and secure tamperproof top closure cover to the burial container, as illustrated in  FIG. 9 . 
         [0065]    This connector forms the top surface and provides a secured closure and maybe accessed via a special security tool that provides for authorized access for locking and unlocking the burial container chamber. As used herein, special security tool means a tool that is not generally available to persons. Without use of the special security tool, persons are not able to open the cinerary urn. 
         [0066]    The top closure cover connector would be a flat circular, octagonal, or other shaped lid that may be constructed such that it can be engraved with information or ornamentation, if desired. 
         [0067]    Additionally, the top closure cover connector could be constructed in a variety of shapes, figures, or ornamental structures including domes, crosses, sun dials, statues, or other objects (not shown). These ornamental structures would be constructed of any weather resistant material and mechanically or adhesively attached to the underlying top closure cover. Since the ornamental structures are separate implements and proprietary or well known to those skilled in the art, further detailed discussion is not deemed necessary. 
         [0068]    The cinerary urn that would be placed in the burial container that is comprised of an elongated, cylindrical canister or vase shaped canister with an interior compartment of sufficient capacity to contain the cremated remains of the deceased. The cinerary urn canister is provided in different sizes to accommodate different volumes of cremated remains from humans, pets, or animals. The cinerary urn would be a two piece container constructed of non-ferrous metal, engineered plastic, glass fiber, carbon fiber or other similar appropriate material. 
         [0069]    The cinerary urn canister would be closed with a threaded closure cover or a permanent closure cover. In the preferred construction, the cylindrical cinerary urn canister is constructed in a predetermined diameter and a variable or fixed length based upon the required capacity. Deceased&#39;s cremated remains are deposited in the cinerary urn canister at the crematorium or funeral home and sealed by the installation of the top lid. A votive offering and/or grave goods may also be included in the urn before the installation of the top lid. 
         [0070]    An optional installation method is to have a burial vault container with the envisioned aperture to receive the cinerary urn(s) with or without an opening in the headstone. If the flat headstone would not contain an opening, the headstone then would be required to be removable to provide access to the burial vault. 
         [0071]    Under certain circumstances, it may be desirable to dispense with the individual cinerary urn canisters and incorporate the cremated ashes of multiple deceased human individuals directly into the burial container. This situation may involve homeless or itinerant persons, unclaimed bodies, or arise from multiple deaths due to accidents, natural disasters, or events under similar circumstances. 
         [0072]      FIG. 8  illustrates a single, double, or multiple cinerary urns with a removable top closure cover  62  to facilitate the interment of cinerary urns at various times. This section drawing depicts a cinerary urn  60  housed in the burial vault  54 . The top closure cover  62  is depicted as a circular disk in shape. However, the size, shape and thickness are variable, including geometric volumes and free form. 
         [0073]    The cinerary urn  60  resides inside the aperture  16  in the headstone  26  and the burial vault  54  with vault cover  56 . The headstone  26  is leveled and attached to the burial vault cover  56  such as with an industrial grade commercially available water-tight leveling compound  28 . 
         [0074]    The cinerary urn top closure cover  62  is adhesively fastened  32  to bond to the headstone  26 . The top closure cover  62  would be secured to the headstone  26  to provide a weather tight and security for the top closure cover. As an option, the top closure cover  62  can be recessed into the headstone  26  with its vertical thickness to be flush with the top surface of the headstone  26 . 
         [0075]      FIG. 9  is a partial section drawing illustrating an optional top closure  64  with two extended flanges to provide additional pressure to secure the top closure cover  64  against the underside of the headstone  26  through aperture  16 . The top closure cover  64  is inserted in aperture  16  in headstone  26  with  2  or more slots ( 4  slots shown) to accommodate the top closure cover  64  flanges and twisted in either direction to secure the top closure cover  64 . The top closure cover  64  is also adhesively fastened  32  to bond to the headstone  26 . 
         [0076]      FIG. 10  is a plan drawing depicting aperture  16  with two slots in headstone  26  to accommodate the top closure  64  with flanges. A four slot option is also envisioned in the headstone to accommodate headstone  26  with four flanges as part of the urn container  60 . As an option, the top closure cover  64  can be recessed into the headstone  26  with its vertical thickness to be flush with the top surface of the headstone  26  or slightly raised above the headstone  26 . This is illustrated by the dashed lines representing the exterior edges of a circular or other shaped top closure cover. 
         [0077]      FIG. 11  represents an option to the urn container  60  to provide two additional flanges that protrude from the sides that are threaded. This flange arrangement provides for the urn canister top cover  64  in the up side down position to become a base for the urn vase  66  to enclose the urn canister  60 . The urn vase  66  has an open bottom with a threaded ring  68  adhesively fastened on the inside at the bottom of the urn vase  66  opening that mechanically attaches to the urn canister  60 . This arrangement provides for a ceremonial urn vase  66  to contain the urn canister  60  during a memorial or remembrance ceremony for the deceased. 
         [0078]      FIG. 12  indicates the urn canister  60  is removed from the urn vase  66 , after the ceremony, and is inserted through the slotted opening in the headstone  26 . The top cover  64  is installed in sealant  32  above the headstone  26  surface and twisted generally in clockwise direction providing a tight fit between the urn canister  60  flanges and the underside of the headstone  26 . In this arrangement the urn canister  60  is interred below the headstone  26  through the opening in the vault cover  56  and into the burial vault  54 . 
         [0079]    A receptacle or attachment mechanism may be provided on the headstone  26  and/or the top lid  12  to facilitate attaching a memorial enhancing object thereto. In certain embodiments, the memorial enhancing object is a figurine or a vase that is adapted to receive flowers. The receptacle or attachment mechanism may be manually operable to facilitate a person attaching or detaching the memorial enhancing object without the use of tools. 
         [0080]    At least one of the components of the burial system may include a genetic material receptacle, which is used to preserve at least one aspect of genetic material from the person whose remains are placed therein. 
         [0081]    In certain embodiments, the genetic material receptacle may have a recess formed therein that is sealed after the genetic material is placed therein. The genetic material receptacle may be attached to or integrated with at least one of the urn, the urn receptacle and the headstone. 
         [0082]    It is the intention of this invention to provide a simple effective burial system for human, pet, or animal cremation remains that respects the traditional practice of complete underground burial of the deceased. This burial system however could also be installed above grade if desired, or required due to geological or hydrological conditions. 
         [0083]    It is possible, as an option, to install the burial container and headstone without a foundation pad or burial vault and in this type of installation the headstone would also function as a support plate and the foundation. 
         [0084]    Although not specifically illustrated in the drawings, it should be understood that additional equipment and/or structural components may be provided as necessary or desired (due to geology, topography, soil conditions, etc.), and that all of the components described are organized and supported in an appropriate manner to form a complete and operative system. Additional cemetery rules or regulations may require additional ancillary accessories or construction for burial in a particular cemetery. 
         [0085]    It is also understood that variations may be made in the present invention without departing from the scope of this invention. For example, the system may employ urns, vases, or canisters of different size, shapes, capacities and/or configurations (not shown) for the interment of cremated remains in lieu of the canisters, urns, vases utilized or illustrated. This is especially true for pet or animal remains. It is contemplated that any one of variety of such modifications and interchangeable canisters may be used in conjunction with this system. 
         [0086]    In the preceding detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top,” “bottom,” “front,” “back,” “leading,” “trailing,” etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The preceding detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims. 
         [0087]    It is contemplated that features disclosed in this application, as well as those described in the above applications incorporated by reference, can be mixed and matched to suit particular circumstances. Various other modifications and changes will be apparent to those of ordinary skill.
