For purposes of convenience and clarity only, directional (up/down, etc.) or position (top/bottom/side) or motional (forward/back, etc.) terms may be used with respect to the drawings. These and similar directional terms should not be construed to limit the scope in any manner. It will also be understood that other embodiments may be utilized without departing from the scope of the present invention, and that the detailed description is not to be taken in a limiting sense, and that elements may be differently positioned, or otherwise noted as in the appended claims without requirements of the written description being required thereto.

[0028] A single capacity burial vault 100 is described herein with reference to FIGS. 1-4, as well as a flat pack kit form as shown in FIG. 3 allowing ready storage, transportation, and assembly for use.

[0029] The single capacity burial vault 100 may be in any convenient form but is shown having a generally rectangular shape and may include six segments or sides, including long lateral sides 102, 104 and shorter lateral sides 106 and 108, a cover or lid 110, and a base 112, that may be assembled by securing the segments to one another to define the rectangular shape.

[0030] When assembled, as shown in FIGS. 1, 2, and 4, the burial vault 100 may have a length L and a height H1 sufficient to accommodate a casket (FIG. 2) during a use within an interior space defined by and bounded by the burial vault 100. At opposing lateral sides of the length of the burial vault 100, the burial vault 100 includes a first long lateral side 102 and a second long lateral side 104. Each of the first lateral side 102 and the second lateral side 104 have length L and height H1. At the foot of the burial vault 100 and coupling the first lateral side 102 to the second lateral side 104 is a lateral side 106. At the head of the burial vault 100 and coupling the first long lateral side 102 to the second long lateral side 104 is a short lateral side 108.

[0031] The base 112 couples the four respective lateral sides, namely sides 102, 104, 106, and 108, and has a length L and a width W. The base 112 may optionally include grooves 112s spanning substantially its whole length L such that straps that are used to lower a casket C into the interior space of the vault 100 may be received upon the supports 112s when the casket C is fully placed upon the base 112 and spaced from a surface of base 112 such that when so placed, support straps (not shown, but supporting a casket C) will not be compressed in place but can be retrieved without disturbing the placement of the casket C within the vault 100 after its placement on the upper surface of the base 112. It will be recognized that supports 112s are shown in a convenient faun for manufacture, but may be in any form suitable for removal of casket-lifting-straps.

[0032] The cover 110 has roughly the same dimensions as the base 112 and may have one or more decorative indicia thereon (shown with three impressed panels), and also couples the four lateral sides 102, 104, 106, and 108 and may include a sealing gasket within an upper groove (not shown). The sides 102, 104, 106, 108, 110, 112 may include mating flange parts such that the sides may be coupled to one another, using fasteners F as will be discussed. It will be understood that the mating flange parts (to be discussed) are shown in one embodiment, but will be understood by those of skill in this art having studied the disclosure as being capable of existing in other forms and shapes adapted for the needs and aspects of the present invention. Herein, the use of captive bolts and slide-in-grooves (to be discussed) provides a convenient manner for hand-assembly without undue post-delivery manufacture or effort.

[0033] When all of the sides 102, 104, 106, 108, 110, and 112 are assembled, no fasteners F are shown, the burial vault 100 may be substantially or completely sealed, with or without a gasket within one or more receiving gasket grooves, or otherwise sealed, and thereby impervious to the penetration of air or liquid into the interior space defined within the burial vault 100 in which the casket C is to be placed. The cover 110 may be releasable or removable from the burial vault 100 such that the interior space may be accessed.

[0034] As noted in FIG. 4, one or more one-way valves may be provided to accommodate decomposition events, moisture seepage, or gas generation. An exemplary one-way moisture valve 300A is shown on base or bottom wall 112 (FIG. 4) and an exemplary one-way gas valve 300B is shown on one of the lateral walls (106 shown) in FIG. 4. In this manner the present invention can accommodate the results of pre-positioning-before-use the burial vault, and then accessing the same years later for actual use by a coffin C, whereby the burial vault is maintained in a dry condition and at a neutral gas-pressure over long periods of time.

[0035] Advantageously, the burial vault 100 may be stored in a flat-pack kit-form, as shown in FIG. 3, which may be easily shipped and easily stored. As shown in FIG. 3, the sides 102, 104, 106, 108, 110, and 112 may have complementary shapes such that they may be stacked in a relatively flat form with curvatures interfitting, and with a cover or top 110 and bottom or base 112 providing secure stacking surfaces. It will be understood that fasteners F (see FIG. 4A) and other elements such as lateral support cross bars 214 (see FIGS. 6 and 7). For example, the long lateral sides 102 and 104, when stacked one atop the other may define a space therebetween in which the short sides 106 and 108 may be positioned. The top 110 and the bottom 112 may sandwich the sides 102 and 104 therebetween such that all the sides 102, 104, 106, 108, 110, and 112 may be stored in a relatively flat form and easily sealed with heavy duty shrink wrap.

[0036] As shown FIGS. 4 and 4A, the lateral sides 102 and 104 may each define generally planar surfaces that include end surfaces 102a, 104a that curve inwardly, thereby generally forming a C-shape on either end. The sides 106 and 108 that form the head and the foot of the burial vault 100 may be generally planar and have projecting mating flanges (as shown). The end surfaces 102a, 104a of the lateral sides 102, 104 may each include an inner projection with a series of receiving grooves 102b, 104b that can receive threaded ends of fasteners F extending through respective captive holes 106b, 108b in extending mating part lips 106a, 108a, or 106p, 108p of the sides 106 and 108. For example, each of the sides 106 and 108 may include (as shown for interfitting) lips 106a, 108a, respectively, on opposing lateral sides running along the height H1. The lips 106a, 108a may each be received within the grooves 102b, 104b defined on opposing sides of the lateral sides 102, 104. The lateral side 104 may similarly include grooves on opposing sides thereof, along its length L, to receive lips 106a and 108a, respectively, of the sides 106 and 108 respectively. Each of the sides 102, 104, 106, 108 include protrusions 102p, 104p, 106p, 108p respectively, at opposing upper and bottom sides with respect to height H1 that are configured to be received within grooves 110c, 112c defined along the perimeter 110a, 112a of the lid 110 and base 112, respectively. Fasteners F are configured to pass through openings 106b, 108b defined within the sides 106, 108 and be captive therein so that their extended threaded shafts engage correspondingly positioned grooves within the base 112 and/or the cover 110, or respective long lateral sides 102, 104 such that once the sides of the burial vault 100 are secured to one another, they will remain so positioned with respect to one another unless the fasteners F are removed. Top or lid 110 is snug-fit and pressure sealed but may be removed after initial assembly for placement of a casket C, as shown in FIG. 2. Fastener F may include a bolt B and a washer S, with the washer S being threadably received onto the bolt, or in other fastener-configurations effective to achieve the needs of the present invention. It will be understood that a single user may easily assemble this burial vault by positioning base or bottom wall 12, and inserting respective fasteners along the bottom holes so that shafts extend. Then fasteners F are extended through holes 106b, 108b in respective end walls 106, 108. Then side walls 102, 104, 106, and 106 are interfit together so that the extending threaded shafts of fasteners F are received within corresponding flange grooves (e.g., 102b, 104b, 106p, and at the bottom of each side wall 102, 104, 106, and 108) and tightened.

[0037] A double capacity burial vault 200 is described with reference to FIGS. 5-9. The double capacity burial vault 200 is substantially similar to the single capacity burial vault 100 except that it is configured to accommodate a plurality of coffins C in a supportive arrangement, and is additionally strengthened to withstand being empty while placed in the ground awaiting future use. As shown in FIG. 6, the double capacity burial vault 200 may contain two coffins C, C one supported over the other. The respective sides 202, 204, 206, 208, and lid or top cover 210, and base or bottom wall 212 correspond to the sides 102, 104, 106, 108, 210, 212, respectively, of the vault 100 except in the ways noted herein. In particular, the height H2 of the vault 200 is greater than the height H1 of the vault 100 as shown in FIG. 5. However, a coffins C typically have standard dimensions, the length L and width W of the vault 200 may be the same as the length L and width W of the vault 100 with the height being different. The base 212 may include supports 212s that are substantially similar to the supports 112s discussed above with respect to the vault 100 to allow for the removal of support straps used to lower coffins C into position.

[0038] To support the weight of the soil that may be applied to the opposing walls or sides 202, 204, along the length L, when the vault 200 is placed within the earth and also to support an upper placed coffin C placed at a shallower depth relative to a lower placed coffin C, the stiffening and rigidizing fool's and structures on the walls (e.g., stiffening geometries) are formed more robustly, as shown. Additionally, for both support of a top casket C, additionally adjustable lateral cross supports or crossbars 214 may span the width W in the interior space of the vault 200.

[0039] As seen best in FIG. 7, the longer lateral sides 202, 204 may additionally each include formed supporting channels 202g, 204g, respectively, that are spaced at predetermined intervals along the respective lengths L of each of the sides 202, 204. The channels 202g, 204g may extend roughly halfway downwardly along the height H2 such that one of the crossbars 214 may be inserted into each channel 202g, 204g, the crossbars 214 are supported by the sides 202, 204 in respective channel ends forming shelves 216 to remain at position roughly halfway along the height 112, thereby dividing the interior space of the vault 200 into roughly equal spaces that can each contain a coffin C.

[0040] The channels 202g, 204g may be at opposing positions relative to one another when the vault 200 is in the assembled state, as shown in FIG. 7, such that when the crossbars 214 are placed within the channels 202g, 204g, the crossbars 214 are generally parallel to one another. Respective shelves 216, formed at the end of each channel 204g, 202g are shaped to receive the end caps 214a of each cross bar 214. A shelf cover 216a may include supports 216s (similar to supports 212s) that are spaced at predetermined intervals such that the supports 216s are spaced to allow removal of flexible support straps after a coffin C is in position. Additionally, shelf cover 216a may include end tabs 216c, shaped to fit within the end of each end channel 202g, 204g on respective shelves 216 to provide a substantial mid-cover over a bottom coffin C (as in FIG. 6) and to accommodate a portion of the end cap 214a of each crossbar 214 therein. The shelf 216a may support one of the coffins C.

[0041] The crossbars 214 each include the end cap 214a at opposing sides with respect to the length of the crossbar 214. The end caps 214a are formed with a manner to be adjustably and threadably received (by threads 214b) onto the ends of each crossbar 214, such that the length of the crossbar 214 (including the endcaps 214a) may be adjusted such that when the crossbar 214 is placed within opposing grooves 202g, 204g of respective sides 202, 204, the endcaps 214a may be adjusted inwardly and outwardly to apply greater pressure upon the lateral sides 202, 204 and that during removal of the crossbar 214 (to position a lower coffin or casket C), the endcaps 214a may be rotated relative to crossbar 214 to shorten its overall length and to facilitate removal of the crossbar 214 from the grooves 202, 204g in which it was placed. It will be recognized that over time, external earth may apply a substantial compression pressure to the outer walls 202, 204 etc., making lifting-removal difficult, so that reducing the length of cross bars 214 while in position (before removal) is essential to aid in their easy removal. The length adjustment may be accomplished in any convenient manner sufficient to meet the needs of the invention and is not limited to the threads 214b as shown, but will be recognized as length adjustment mechanisms, including but not limited to wedge-arrangements, channel-groove arrangements, pin-hole arrangements, and others.

[0042] Just as with vault 100, as shown in FIG. 9, the components of the vault 200 may be stored in a flat-pack kit form to save space during storage. During use, the vault 200 may be assembled in a similar manner to the vault 100 using a plurality of respective captive fasteners F (not shown) received within a suitable arrangement of holes 206b, 208b on extensions 206a, 208a, and grooves 202b, 204b on respective flanges 202a, 204a into respective. A first coffin C may be placed within the vault 200 and placed upon the base 212. Crossbars 214 may then be inserted within the channels 202g, 204g, respectively, end caps 214a adjusted to secure length on respective shelves 216 in respective channels 202g, 204g, and then the shelf cover 216a may be placed thereupon. Thereafter, a second coffin C may be placed upon the shelf cover 216a. The cover 210 may then be secured to the sides 202, 204, 206, 208 to seal the vault 200.

[0043] The burial vaults 100, 200 as discussed herein may be made of any suitable material or mix of materials for the purpose noted herein, including plastic including for example ABS and PVC type plastics, fiberglass, carbon fiber, metal, polymer matrix compositions and otherwise. Similarly, the components such as the cross bars 214 (likely metal, but also reinforced fiberglass, plastics of any type, concrete, etc.), pressure relief valves 300A, 300B, gaskets and fasteners F, can all be made of any suitable material for the purposes as discussed herein.
