FIELD OF THE INVENTION
The present invention generally relates to a modular casket or coffin.
BACKGROUND OF THE INVENTION
Caskets or coffins are typically purchased during a stressful time shortly after the unfortunate need arises due to the death of a loved one. Although caskets have been traditionally purchased through a funeral home, caskets could be more available from alternative point of sale locations such as directly from a funeral supply stores, the internet, and retail locations. The available selection of caskets, however, is mostly limited to steel or wood caskets that are expensive. The bulky steel or wood caskets are also difficult to ship and prone to damage during shipment which increases the difficulty of using alternative point of sale locations. Caskets also occupy considerable space when stored and require climate controlled storage. Consequently, a need exists for a less expensive casket. A need also exists for a modular casket that can be easily shipped and assembled and can be stored in a non-climate controlled facility.

DETAILED DESCRIPTION
FIG. 1 is a top perspective view of the casket in accordance with one embodiment of the present invention. As used herein, the term “casket” is synonymous with and meant to include the term “coffin.” FIG. 2 is a bottom perspective view of the casket in accordance with one embodiment of the present invention. FIG. 3 is an overall exploded perspective view of the casket in accordance with one embodiment of the present invention. Referring to FIG. 3, the casket comprises a pair of opposed sidewalls 110. The same reference numbers are used to identify the same corresponding elements throughout all drawings unless otherwise noted. The sidewalls 110 comprise one or more side panels 120. In one embodiment, each sidewall 110 comprises a pair of side panels 120 slidably connected together by a wedge member 130. Each side panel 120 comprises a vertical side 122 designed to be slidably attached to a vertical end panel side 141 142. It should be pointed out that the “vertical” end panel sides 141 142 do not need to be vertical and such sides can be rounded. The term “vertical” is simply used to denote the side 141 142 of the end panel 140 that is attached to the side panel 120. Similarly, the vertical side 122 of the side panel 120 can be rounded or any other shape and is simply called “vertical” to denote the side 122 of the side panel 120 that is attached to the end panel 140. The base section can comprise one or more pieces. In one embodiment, the base section comprises two base ends 210 and a middle base portion 220. The base section can be attached to the opposed side panels 120 and/or said opposed end panels 140.
The lid can comprise one or more sections. In one embodiment, a first lid section 310 and a second lid section 320 can be attached to the sidewall 110. In one embodiment, the first lid section 310 is attached to a first side panel 120 and the second lid section 320 is attached to an adjacent second side panel 120.
The base section, side walls, end panels, and lid can comprise a plastic composition. Although the base section, side walls, end panels, and lid components and the hinge assembly can be formed from a variety of different materials using different manufacturing techniques, in the subject embodiment, they are injection molded from a suitable plastic containing fibers for reinforcement. Plastics that can be used include, but are not limited to ABS, polycarbonate, fiberglass, metals, and mixtures thereof. Any injection molded composition can be used. As used herein, an “injection molded composition” is defined as any material, resin or composite that can be injection molded. It should be further noted that different additives can be used for different injection molded parts. Strengthening ribs and other complex structures can be provided to make the components more rigid.
As shown in FIG. 3, each side panel 120 comprises one rounded edge near the end panel 140. Such illustration is just one example of how a rounded corner can be provided. In one embodiment (not shown), the end panel comprises one or more rounded corners. In one embodiment (not shown), a side panel comprises a rounded corner. Some consumers deem rounded corners to be desirable in caskets and caskets having rounded corners are more expensive to manufacture and are consequently more expensive in the marketplace. For example, the expenses of making a metal or steel casket with a rounded edge are significant because of the forming/stamping/pressing operation that is required to form the metal or steel material. Such forming equipment is expensive. Consequently, steel and metal caskets are typically cut to length and welded together to form square corners. However, caskets made of sheet metal are still labor intensive because of the welding and grinding that is required in putting the caskets together. Wood caskets more typically have rounded corners, but wood is relatively heavy, bulky, and expensive to ship. Both metal and wood caskets, if not assembled prior to shipment, are difficult to assemble at a point of distribution or use, unlike the present invention, which is easy to assemble for reasons discussed in more detail below.
FIG. 4 is a partial cutaway detailed view depicting the connection between a side panel 120, an end panel 140, and a base section 210 in accordance with one embodiment of the present invention. In the embodiment shown, the end panel 140 is sized to be slidably connected into the side panel 120 receiving cavity 128. As used herein the term “slidably connected” and the term “slidably attached” is defined by the attachment or connection of two pieces such that the pieces are pressure-fit together. “Pressure-fit,” is a term known to those skilled in the art. The term can refer to a bond caused by mutual pressure acting on the contact surfaces between two parts in contact, wherein the two parts require no weld, screw, or nail connection. Thus, in one embodiment, the side panel 120 and receiving cavity 128 are sized to maximize the contact between the side panel 120 outer periphery and receiving cavity 128 inner periphery. In addition, a male member 136 on the end panel 140 is located so as to snap-fit into a female member 138 located on the side panel 120. Such members 136 138 help to further lock the two pieces together and secure the two pieces in place. Such members not only help hold the two pieces together, but they also further signal the assembler that the connection is complete. It should be pointed out that this specific connection is provided for purposes of illustration and not limitation. There can be any number of male and female pairs in any configuration. For example, in an embodiment not shown, similar male and female members are provided on the base section 210 and end panel 140 to further lock the end panel 140 and base section 210 together and/or signal the assembler that the connection is complete. In one embodiment not shown, similar male and female members are provided on the base section and side panel for similar reasons.
It should also be pointed out that the panels can be designed such that a side panel is sized to be slidably connected to an end panel receiving cavity (not shown). Such embodiment can occur if the end panel 140 is rounded and the side panel 120 is flat at the corner connection.
As shown in FIG. 4, in one embodiment, the base end 210 comprises L-shaped female side panel interlocking members 229 that can slidably connect to an L-shaped male side panel locking member 129. Similarly, the base end 210 comprises an L-shaped female end panel interlocking member 249 that can slidably connect to an L-shaped male end panel locking member 149. It should be pointed out that while the embodiment depicted and discussed with reference to FIG. 4 is directed towards L-shaped slots, any shape (tapered or untapered, L-shaped, T-shaped, etc.), number, and combination (male member on base and female on panel or female on panel and male on base) of interlocking-shaped members that can be used to slidably connect the base section 210 to the side panel 120 and/or end panel 140 does not depart from the spirit and scope of the present invention.
FIG. 5a is an exploded perspective side view depicting the connection of two side panels 120 by a wedge member 130 in accordance with one embodiment of the present invention. Although the wedge member 130 shown depicts three pair of T-shaped female slots 132, the wedge member 130 can comprise any combination (number, shape, placement of male/female) of interlocking members. In one aspect, an interlocking member is a male member or a female member. Providing interlocking members as an integral part of the side panels, end panels, and base section allows the interlocking in as many places as is required without the need for a separate weld, nail, screw, nut, bolt, or adhesive. In one embodiment, the wedge member 130 comprises one or more female T-shaped slots. Further, the wedge member 130 can comprise one or more pairs of T-shaped male protrusions and/or one or more pairs of T-shaped female slots. Similarly, the side panels 120 can comprise one or more pairs of T-shaped male protrusions or female slots. In one embodiment the T-shaped female slots 132 and T-shaped male protrusions 134 disposed on the side panels 120 are tapered. Thus, in one embodiment, the male T-shaped protrusions 134 comprise a first distance D1 at the inner portion of the side panel 120 and a second, larger distance D2 at the outer portion of the side panel 120. Similarly, in one embodiment, the female T-shaped slots 132 comprise a first distance D1 at the inner portion of the female slot 132 and a second, larger distance D2 at the outer portion of the female slot 132. Of course, the tapering can be reversed resulting in a second, smaller distance D2. The male protrusions 134 and female T-shaped slots 132 slidably connect to adjoin the two side panels 120 in a sturdy fashion. In one embodiment, the wedge 130 and side panel are sized to maximize contact between the outer wedge periphery 131 and a portion of the inner side panel periphery 121. Male 136 and female 138 locking members can be provided to lock the wedge member 130 into place between the two side panels 120.
Although not necessary, in one embodiment, the first side panel 120 comprises a plurality of tapered or non-tapered integral alignment protrusions 182 that can be aligned with a plurality of corresponding tapered or non-tapered alignment slots 184 integral to a second side panel 120. A locking frame 135 on the wedge member 130 can be used to lock the alignment protrusions 182 and alignment slots 184 in place and help absorb any shock loads on the sidewall assembly.
The above-described configuration is beneficial for several reasons. First, the wedge member 130 permits side panels 120 to be fastened together with virtually no tools. At most, a rubber mallet may be required to force the wedge member 130 into place between the two side panels 120. Second, the configuration of the T-shaped protrusions and slots distributes any forces or tension placed on the wall joint over a larger area. Third, because the T-shaped protrusions and slots are oriented parallel to any normal forces exerted on the panels, e.g. forces that are perpendicular to the plane of the side panels, a sturdy connection can be made at the joint between the two side panels 120. Thus, the T-shaped protrusions and slots provide a resistance to forces normal to the side panel connection. Fourth, because the connection is intuitive to the user, the design facilitates assembly. Fifth, because no screws or nails are required, the connection can be made relatively quickly leading to more efficient casket assembly. Further, such connection is superior to nuts, bolts, screws, or nails because the fastening force is distributed over a larger surface area. Sixth, the connection can also be disassembled with few or no tools.
While several embodiments discussed above are directed towards T-shaped protrusions and slots, any type and number of tapered or non-tapered interlocking-shaped members can be used to slidably connect two side panels 120 together with a wedge member 130 without departing from the spirit and scope of the present invention. For example, FIG. 5b is an exploded perspective side view depicting the connection of two side panels 120 by a wedge member 130 in accordance with an alternative embodiment of the present invention. Referring to FIG. 5b, the I-shaped wedge member 130 comprises a hollow cylinder comprising a slot 132 in the center of the hollow cylinder. The side panel 120 comprises a smaller cylindrical protrusion 134 sized such that it can be snugly placed into the slot 132. In one embodiment, the wedge 130 and an integral portion of the inner side panel periphery 121 are sized to maximize contact between the outer wedge periphery 131 and a portion of the inner side panel periphery 121. The protrusion 134 and corresponding slot 132 can be tapered or non-tapered and may have male or female members (not shown) similar to those identified as numerals 136 and 138 in FIG. 4 to help the wedge member snap into place. Further, in one embodiment, another fastening means including but not limited to a wingnut with or without a washer (not shown), cotter pin or other device can be inserted through the protrusion 134 and slot 132.
Further, other ways of fastening the side panels with minimal use of tools can also be provided without departing from the spirit and scope of the present invention. In one embodiment, casket components such as two or more side panels are pressure fit together. In one embodiment, two or more side panels are pressure fit together by a twist lock fastener. For example, FIG. 5c is an exploded perspective side view depicting the connection of two side panels 180 by a twist lock fastener in accordance with one embodiment of the present invention. As shown in FIG. 5c, each side panel 180 can be molded to include a plurality of cam receiving housings 280. An aperture 186 can be provided adjacent the housing 280 to permit placement of a dowel 284. A first side panel 180 can comprise a plurality of tapered or non-tapered alignment protrusions 182 that can be aligned with a plurality of corresponding tapered or non-tapered alignment slots 184 integral to a second side panel 180. The alignment slots 184 and alignment protrusions 182 can help to align the two side panels 180 during assembly. The first and second side panels 180 can then be pressure-fit and secured together by a twist lock fastener. In the embodiment shown, the twist lock fastener comprises two cams 282 and a dowel 284. The dowel 284 is placed into a housing 280 and through the aperture 186 such that the dowel 284 resides partially in a housing 280 of each side panel 180. A cam 282 can then be placed into each housing 280 over the dowel 284 and each cam 282 can then be turned in the direction of the arrow 286 to secure the side panels 180 together. Although the cam 282 can be configured such that it can be turned with a screwdriver as is depicted in FIG. 5c, the cam 282, in an embodiment not shown, can also be configured to have an extension similar to a wing nut that can be hand-tightened to help reduce the number of or eliminate all tools required for assembly. In one embodiment, a single cam can be used with a dowel designed for single cam fastening.
FIG. 6a is a perspective view showing how the base section can be further secured to a side panel in accordance with one embodiment of the present invention. As depicted in FIG. 4, the base section 210 slidably connects to the side panel 120 and the clip 240, as depicted in FIG. 6a, can be used merely add support and help secure the connection under heavier loads. One or more clips 240 can be used to further secure each side of a base end 210 and/or a middle base portion 220 to the side panel 120 and/or the end panel 140. In one embodiment, one or more clips 240 are used at or near joints between the base end 210 and the middle base portion 220. Such configuration is beneficial for several reasons.
First, the clips 240 permit the side panels 120 to be securely fastened to the base end 210 or middle base portion 220 with no tools. Second, because the connection is intuitive to the user, the design facilitates assembly. Third, because no screws or nails are required, the connection can be made relatively quickly leading to more efficient casket assembly.
In one embodiment, the clip 240 mouth is designed to be slightly smaller than the ribs inside a side panel 120 or end panel 140 (not shown) or the base end 210 and/or base portion 220. This enables the clip 240 to pressure-fit onto and retain the ribs of the side panel 120 and portion of the base end 210 and/or base portion 220 to better secure the connection between the side panel 120 and any base section 210 220. Also depicted in FIG. 6a is a side panel handrail receiving member 124 which is discussed in more detail below.
FIG. 6b is a perspective view depicting a base section in accordance with an alternative embodiment of the present invention. A portion 612 of the base section 610 is disposed on the side panel ledge 232. A stiffening bar 630, made of metal or plastic, can be placed into a housing 632 disposed near the side panel ledge 232. In one embodiment, the housing 632 is integral with the side panel 180. A joint protrusion 640 can be provided to help hold the base section 610 in the proper position during and after assembly.
FIG. 7 is a perspective view of a partially constructed casket in accordance with one embodiment of the present invention. In one embodiment, one or more side panel handrail receiving members 124 are formed integrally with each side panel 120. In an alternative embodiment (not shown), one or more handrail receiving members are formed integrally with a base section. Thus, in one embodiment, at least one side panel or base section further comprises one or more handrail receiving members 124 wherein the handrail receiving member is integral to the side panel or base section. One advantage of an integral handrail receiving member 124 is that forces imparted through the hole to the handrail receiving member 124 by a handrail are spread more evenly over a larger area than would occur if the handrail receiving member 124 were attached by some type of fastener. Consequently, an integral handrail receiving member 124 has greater strength and can withstand a heavier load that a non-integral, fastened handrail receiving member. Another advantage is that the hole in the handrail receiving member can be formed at the same time as the side panel or base section resulting in less assembly to the end-user.
FIG. 8 is a perspective view depicting the pallbearer handrail 160 in accordance with one embodiment of the present invention. Referring to FIG. 7 and FIG. 8, the side panel handrail receiving members 124 each comprise a hole for insertion of the handrail 160. In one embodiment, the handrail 160 comprises four separate rails; two long handrails disposed through the handrail receiving members 124 and two shorter handrails adjacent the end panels 140. Once the casket in FIG. 7 has been constructed, decorative handrail covers 126 can be snap-fit over the side panel 120 handrail receiving members 124. The decorative handrail covers 126 146 156 can comprise any decorative design feature including a cross or other emblem. The long handrails can then be inserted through the holes in the receiving members 124. The shorter handrails can then be inserted through the decorative end panel covers 146 and through the four corner handrail covers 156. One advantage of such a configuration is that it permits attachment of a handrail without the use of tools. A coupling or corner union (not shown) inside the corner handrail covers 156 connects the shorter handrails to the longer handrails. Any of the decorative handrail covers 126 146 156 can be attached by any number of ways including a snap-fit connection, a fastener connection including a nut or bolt or screw, an adhesive such as double-sided tape, and/or can be held into place by the handrail 160 itself. In one embodiment, the handrail 160 comprises two separate rails adjacent the side panels 120.
FIG. 9a is a partial cutaway exploded view of the inside of one end of the casket in accordance with one embodiment of the present invention. FIG. 9b is an exploded perspective view depicting the hinge assembly in accordance with one embodiment of the present invention. Referring to FIGS. 9a and 9b, the hinge assembly 400 comprises a hinge base 410 slidably connected into a hinge slot 420, wherein the hinge slot 420 is located on the top portion of the side panel 120. Two pieces comprising a hinge pin 440 can be placed into a receiving hole in the hinge base 410 and press-fit together. In one embodiment, the entire hinge assembly 400 is made from an injection molded plastic. One or more hinge pin 440 receiving members 450 can be integral to the first lid section 310 and/or second lid section 320. In one embodiment, screws 435 can be used to attach a hinge bracket 430 to the lid 310 320. In one embodiment, only a screwdriver is needed to attach the hinge assembly 400 to the lid 310 320. Consequently, in one embodiment of the present invention, the casket can be assembled with minimal tools, the only tools potentially necessary being a screwdriver and a rubber mallet. It should also be pointed out that the screws 435 can be replaced with a screw having a configuration that can permit the hinge to be fastened to the lid 310 320 in a manner that requires no tools. For example, a pair of screws 435 having an extension similar to a wing nut that can be hand-tightened can be used. In one embodiment, such extension does not exceed the diameter of the head of the screw 435. In one embodiment, a cotter-pin type fastener is used. Thus, some embodiments of the present invention provide a modular casket that requires no tools for assembly.
FIG. 9c is a partial exploded perspective view depicting the lid assembly in accordance with one embodiment of the present invention. Referring to FIGS. 9a and 9c, a lid frame 330 can be placed about the inner periphery of the lid 310. The lid frame 330 can be injection molded such that a plurality of metal heart-shaped clips 314 can be snap-fit onto the lid frame 330, as best shown by FIG. 9a. The mouth end of the metal clip 314 can engage a corresponding rib on the lid 310 to hold the lid frame 330 in place. Because the metal clip 314 comprises a sharp mouth surface, the mouth surface can grip an adjoining rib. A lid frame can similarly be joined to any other lid sections including a second lid section 320.
FIG. 9d is a partial cutaway view depicting the end of the casket from the inside in accordance with one embodiment of the present invention. Referring to FIGS. 9a and 9d, in one embodiment, the casket comprises a casket frame 340 and gasket 350 disposed about the outer, upper perimeter of the side panels 120 and end panels 140. The casket frame 340 can provide aesthetic features such as a lip 342. The casket frame 340 can be attached to the side panels 120 and end panels 140 by a plurality of metal clips 344 in the same manner that the lid frame is attached to the lid 310 as discussed above.
In one embodiment, a fabric covers the inside of the side panels 120 and end panels 140. The fabric can be attached to the upper side panels 120 and end panels 140 by the metal clips 344. In one embodiment, a pan 230 is placed in the bottom of the casket. A fabric material may or may not also cover the pan 230. In one embodiment an inflatable air mattress is also placed into the casket to provide the desired elevation of the body in an open casket or other ceremony. The gasket 350 can be attached by an adhesive. A simple arm assembly 360 can be attached to the lid locking arm mount 362 and the end panel locking arm mount 364 to prevent the lid from opening too widely. Each of these arm mounts 362 364 can be integrally injection molded with their respective pieces. Also shown in FIG. 9d are the wingnuts 148 used to fasten the decorative end panel handrail cover to the outside of the end panel 140.
FIG. 10a is a partial cutaway view of the portion labeled FIG. 10A in FIG. 9a depicting the locking mechanism in accordance with one embodiment of the present invention. FIG. 10b is an alternative partial cutaway view depicting the locking mechanism depicted in FIG. 10a. Referring to FIGS. 10a and 10b, in one embodiment, a latch assembly comprises a clip 514, a male latch 510, and a female latch 530. In one embodiment, the clip 514 comprises a raised collar 516 that can be press fit around the cylindrical tip 518 integral to the latch 510. In one embodiment, the mouth of the clip 514 can then be press-fit onto a rib 312 integral to a lid section 310 320. A female latch 530 can be slidably attached to the top portion of the sidewall 120. A male latch ledge 512 mates with a female latch ledge 532 after insertion into the female latch 530. One advantage of such configuration is that no latches are visible on the outside of the casket. Thus, the latch is not fastened to an outer periphery of the side panel or lid.
To open, a rigid, flat card (e.g. a credit-card like object) can be placed between the lid frame 330 and the side panel 120 and can be used to push the male latch 510 inward to permit the lid 310 to open. In one embodiment a resilient, rubber-like L-shaped gasket 350 is about the upper perimeter of the side panel 120 and the credit card-like object can press a portion of the gasket 350 into the male latch 510 to permit the lid 310 to open.
One skilled in the art would recognize that such feature could be reversed and in one embodiment the female latch portion 530 is attached to the lid 310 320 and the male portion 510 extends from the side panel 120. Similarly, one skilled in the art would recognize that both the female latch 530 and male latch 510 can be attached to the lid 310 320 or the side panel 120 by a clip or by a pressure-fit mount. The present invention should therefore be construed to include all embodiments wherein male 510 or female latch 530 is attached to a lid 310 320, and wherein further said male latch 510 or said female latch 530 removably fastens the lid 310 320 to the side panel 120, wherein said latch assembly is snap-fit together. Another advantage of such configuration is that no tools are required to attach the latch assembly to the side panel 120 or lid 310 320. In one embodiment, the male latch 510 is secured to the lid with one or more screws.
FIG. 11 is a top perspective view of the casket in accordance with one embodiment of the present invention. Like traditional caskets, the present casket provides an open casket viewing option.
FIG. 12 is a simplified perspective view of illustrating the packing configuration of the kit for making a modular casket in accordance with one embodiment of the present invention. As shown in FIG. 12, the various parts of the casket can be efficiently packaged as a kit in compact form for shipment or storage until partial or full assembly is desired. In one embodiment, the lid sections 310 can be adjacent one another and alternatively nested. The side panels 120 can be can be grouped together between the lid section 310 and a base pan 230. Nested within the base pan 230 can be one or more nested base sections (not shown). Adjacent end panels 140 can be oriented perpendicular to the side panels 120 or lid 310. In one embodiment (not shown), the kit comprises two end panels, two sidewalls and a base section. It should be pointed out that the exemplary packing configuration depicted in FIG. 12 is for purposes of illustration and not for purposes of limitation. Any compact or efficient shipping configuration can be used that minimizes the storage volume required by a disassembled casket. In one embodiment, the stored or packaged volume of the casket is approximately 50% less than the assembled volume or volume of the casket when fully assembled. The disassembled casket comprising the kit for making the modular casket can then be placed into a shipping container to protect the casket from damage during shipment.

As shown in FIG. 14a, prior to attaching the end panel 140 to a side panel 120, the side panel-to-end panel seal 740 can be placed on the vertical sides 141 142 of the end panel 140 at least about the outer-most outward facing perimeter of the end panel 140. In such embodiment, the side panel-to-end panel seal 740 preferably comprises a pressure sensitive adhesive on both a first side to facilitate bonding with an end panel 140 and on a second side to facilitate bonding with a side panel 120 upon slidable attachment of the end panel 140 and side panel 120.
FIG. 14b is a perspective view depicting a side panel-to-side panel seal 720 in accordance with various embodiments of the present invention. As shown in FIG. 14b, a side panel to side panel seal 720 can be attached to the outer facing perimeter of at least one of the two side panels to provide a seal between the side panels once they have been slidably connected and pressure fit together by, for example, a wedge member or in any other way contemplated by the present invention.
FIG. 15a is a partial exploded perspective view depicting a support member in accordance with various embodiments of the present invention. As shown in FIG. 15a, at least one support member 810 and preferably a U-shaped support member 810 is attached to each sidewall that is shown in FIG. 15a as opposing sidewalls and to each base section. Consequently, in one embodiment, a U-shaped support member 810 is attached in at least three places to the modular casket. In one embodiment, the support member 810 is substantially tubular in cross-section and can comprise a metal, a plastic or other suitable material. In one embodiment, the support is extruded as a round, square, or triangular hollow rod and then configured, through bending, into a U-shaped support adapted to attach within the cavity of the casket as shown in FIG. 15a. In one embodiment, each vertical side of the support member 810 is attached to a handrail receiving member 124 by a single screw that fastens both the handrail receiving member 124 and the support member 810 to the side panel 120. In one embodiment each vertical side of a U-shaped support member 810 is attached to a handrail receiving member 124. In one embodiment at least two support members 810 are attached to said modular casket and in one embodiment between about two and about four support members 810 are used. A screw or other fastening means well known in the art can be used.
FIG. 15b is a partial exploded perspective view depicting a rod 820 in accordance with various embodiments of the present invention. In one embodiment, each sidewall comprises one or more rods 820 secured along at least a portion of the length of the sidewall to provide reinforcement along the longitudinal axis of the casket. In one embodiment, placement of one or more rods 820 is achieved after casket assembly by removing a removable portion 830 of the end panel 140 and by placing the rod 820 through a plurality of apertures 840 placed into the ribs of the inner sidewall. Such embodiment advantageously permits easy removal of a metal rod 820 and permits the casket, made of entirely of plastic materials in one embodiment, to be recycled in regions where caskets are buried for a limited time. Further, if cremation occurs, the rods can be removed prior to cremation without disassembling the casket. In an alternative embodiment, one or more rods can be secured to a sidewall by a plurality of screws or other fastening means well known in the art.
The rigidity of a modular plastic casket is greatly improved by the use of one or more rods 820 and one or more support members 810. One way to measure rigidity improvement is to compare how much the casket flexes or the height that can be achieved when lifting a corner of the casket while at the same time keeping the two corners on the far opposite side tightly attached to the floor. In one embodiment, a modular casket made of thermoplastic components flexes up to two inches (e.g., a lifting corner can be lifted up to two inches while the far opposite corners are held down) without any rods 820 or support members 810. The addition of two cylindrical 1-inch diameter support rods made from steel and placed into each sidewall and the addition of one U-shaped support member 810 attached to opposing sidewalls and a base section flexes only 1⁄4-inches. Consequently, in one embodiment, use of support members 810 and rods 820 improves rigidity by a factor of eight.
The present invention provides numerous advantages over the prior art. First, the plastic caskets of the present invention are less expensive to fabricate than the traditional wood or steel caskets. Second, the casket can be easily shipped as a more compact set of parts than a traditional wood or steel casket, or a non-modular casket fabricated from other materials. Further, because plastic is lighter than wood or metal, the casket of the present invention is not only less expensive to ship, but easier to handle, both in unassembled and assembled form. Further, the casket can be easily moved and stored.
Third, the casket of the present invention can be quickly and easily constructed and assembled by a funeral home or by an individual with little or no assembly experience. The only tools that may be required include a rubber mallet and a screwdriver. The assembly of the snap-fit and pressure-fit pieces is intuitive in the way in which the pieces are put together. Such advantages can be useful in areas of natural disasters. Such advantage also provides the ability to direct-market the casket to consumers through a phone number or web-site without the added expense of a middle man. Further, the casket can be marketed to consumers through stores by-passing the traditional funeral home and resultant mark-up.
Fourth, the casket is made of materials that is more durable than the prior art caskets. For example, unlike wood, plastic does not swell or deform. Unlike metal, plastic does not rust or dent. Further, when the casket of the present invention is packed, it can be shipped without worry of exposure to the elements. For example, the caskets and casket kits of the present invention can be stored outside with worry of exposure to the elements including, but not limited to temperature, humidity, moisture, blowing sand, etc. Such advantage can be useful in areas of natural disasters. Wood, on the other hand, must be stored in controlled climate conditions. Similarly, metal-type caskets, if subjected to high humidity or moisture conditions, are susceptible to rust, especially if any scratches were made through the painted metal during shipment. Thus, the present invention provides a casket that is more durable under both shipping and storage conditions.
Fifth, the casket can be made to emulate the caskets of wood design or steel designs. For example, a wood grain finish can be imparted into the injection molded plastic. Further, rounded corners used in wood caskets can be provided in plastic caskets of the present invention. Further, the color of the plastic can be easily changed to emulate steel-type colors. Moreover, the casket of the present invention has the same accessories as caskets of the prior art. Consequently, the present invention provides a casket having a similar look and design as prior art caskets with lower costs. Thus, there is little or no stigma attached to using a casket made from less expensive plastic materials of the present invention.
It will now be evident to those skilled in the art that there has been described herein a modular casket or coffin. The terms and expressions employed herein have been used as terms of description and not of limitation; and thus, there is no intent of excluding equivalents, but on the contrary it is intended to cover any and all equivalents that may be employed without departing from the spirit and scope of the invention.
