RELATED APPLICATIONS 
     This application is a continuation-in-part application of application Ser. No. 08/564,387, filed Nov. 29, 1995, now abandoned, the entire substance of which is hereby incorporated by reference herein as if fully set forth in its entirety. 
    
    
     FIELD OF THE INVENTION 
     This invention relates generally to burial caskets, and more particularly to a method of shipment of a burial casket in a knocked-down configuration and subsequent assembly of the casket at its point of destination as well as a casket shipped and assembled by the method. 
     BACKGROUND OF THE INVENTION 
     A casket comprises a large shell to which is pivoted a cap or lid. Caskets are generally expensive to ship due to the large volume of wasted space which is the interior of the casket. 
     So-called ready-to-assemble caskets have been proposed in order to provide more economical shipping of caskets. A ready-to-assemble (&#34;RA&#34;) casket is generally shipped in a knocked-down kit configuration, that is, is shipped as a kit of disassembled casket components, for example a pair of shell side walls, a pair of shell end walls, a shell bottom wall, and a cap. The disassembled casket components may be shipped in a shipping container which is substantially smaller than a container for containing an assembled casket. Thus, for a given volume, a greater number of caskets may be shipped in RA form than in preassembled form thereby producing a substantial shipping cost savings. 
     One criticism in the shipping of RA caskets, and many other products for that matter, is the amount of waste generated at the shipping destination point of the caskets. The RA casket is removed from its shipping container, is assembled and readied for sale. The shipping containers, normally fabricated of corrugated board otherwise known as cardboard, must either be disposed of or transported to a recycling station for recycling. The cost of this discarded and, prior to the present invention, unusable, shipping container traditionally is reflected in the cost of the end product--the casket--thus increasing the casket&#39;s cost. 
     In addition to being utilized in the construction of shipping cartons cardboard has also been employed in the construction of combustible caskets used in the cremation industry or so-called crematable caskets. Cardboard has the advantage of being much less expensive than wood but suffers however from the drawbacks that it is not as aesthetically pleasing visually as are caskets fabricated from wood or other materials such as hardboard and also cardboard is not as structurally stiff as some of these other materials used for fabricating crematable caskets and thus has a lesser load carrying or bearing capacity. Cardboard can though be successfully employed in crematable caskets for components which do not carry great loads and which also are not ordinarily visible to an observer of the casket due to their being covered by the decorative fabric interior of the casket or otherwise to their placement within the casket. 
     It is therefore one objective of the present invention to reduce shipping container waste at the point of destination of RA caskets. 
     It is another objective of the present invention to reduce the need to transport discarded shipping containers in which RA caskets have been shipped to a recycling station for recycling. 
     It is yet another objective of the present invention to reduce the shipping costs associated with shipping caskets in general and RA caskets in particular. 
     It is still another objective of the present invention to utilize cardboard as a material with which to fabricate at least some components of a crematable casket, which components are not required to carry great loads and are not readily visible to an observer.

The end walls 50, 50 are first folded upwardly about score lines 48, 48 and then carton bottom side walls 42, 42 are folded upwardly about score lines 40, 40. End flaps 54, 54 are folded about a respective score line 48 inwardly about each of the end walls 50, 50, and the locking tab 58 of each end flap 54 is folded about score line 59 upwardly and inserted first through a respective slot 60 and then into a respective slot 62 in a respective end wall 50 thereby locking the side walls 42, 42 and end walls 50, 50 in their upright, erected positions. 
     Referring now to FIG. 3, the cardboard blank 31 from which can be constructed both the shipping carton top 14 and a casket floor which will be subsequently described is illustrated. The blank 31 includes a pair of opposed lateral edges 92, 92 and a pair of opposed edges 94, 94 defining a carton top ceiling 96 and a casket floor portion 98. A first longitudinal pair of score lines 100, 100 defines a pair of carton top side walls 102, 102. A second longitudinal pair of score lines 104, 104 defines the lateral edges of the floor portion 98 and longitudinal reinforcing structure for each lateral edge of the floor portion 98. A transverse score line 106 inboard of each end edge 94 defines a carton top end wall 108. A pair of longitudinal cut lines 110, 110 in each end edge 94 further defines each end wall 94 and also defines a pair of end flaps 112, 112. One cut line of the pair of cut lines 110, 110 extends inwardly from a respective end edge 94 to a respective transverse score line 106 and to a respective end of a respective longitudinal score line 100 of the first longitudinal pair of score lines 100, 100. A transverse cut line 114 extends partially laterally outwardly from each longitudinal cut line 110 and defines a locking tab 116 of each end flap 112 foldable about a score line 117. A pair of notches 118, 118 in each end wall 108 accept the locking tabs 116, 116 of the end flaps 112, 112. A second pair of notches 120, 120 in the carton top ceiling 96 adjacent each transverse score line 114 are also for accepting the locking tabs 116, 116 of the end flaps 112, 112. A pair of transverse score lines 122, 122 intermediate the end edges 94, 94 define torso reinforcing structure formed by folding the cardboard sheet in a lapped configuration, which will be subsequently described in more detail. 
     Referring now to FIG. 4, it will be seen that the carton top 14 is assembled from its blank 31 in much the same manner as the carton bottom 12 is formed from its blank 30. The end walls 108, 108 are first folded upwardly about score lines 106, 106, and then the side walls 102, 102 are folded upwardly about score lines 100, 100. The locking tab 116 in each end flap 112 is folded upwardly about score line 117, and the end flaps 112, 112 are folded at respective score lines 106 about the end walls 108, 108. Locking tabs 116 are inserted through notches 118 and 120 thus forming the erected carton top 14. 
     The carton 10 is thus erected and is ready for accepting the kit 16 of casket components therein for shipment to a destination point. 
     Once the container 10 including casket kit 16 arrives at the destination point, the kit 16 is removed from the container 10 and is assembled into the casket, for example the casket designated generally by the numeral 26 in FIG. 1. The bottom 12 and top 14 of the shipping carton 10 may then be disassembled back into their blank 30, 31 forms and then may be re-erected into interior components of the casket 26. The carton bottom 12 is erectable into a body support structure 130 (FIGS. 6-9), and the carton top 14 is erectable into a casket floor 132 (FIG. 10). 
     Referring now to FIGS. 6-9, erection of the body support structure 130 from the blank 30, previously erected into carton bottom 12 for shipping the kit 16 of the casket components, will be described. End portions 132 of the blank 30 defined at each opposed end by transverse lines of perforations 80 are first detached from the balance of the blank 30 to shorten the body support structure 130 such as will fit within the length of the casket 26. Next the longitudinal supporting structure 134 for each lateral edge of the body support structure 130 is formed by folding a lateral edge portion of the cardboard sheet blank 30 beneath the body supporting portion 38 by folding along the score lines 44, 44 and along the score lines 40, 40 to form a first panel portion 46 and a second panel portion 42 of each longitudinal supporting structure 130. The first panel portions 46 are folded to be generally perpendicular to the body supporting portion 38 and the second panel portions 42 are folded so as to underlie the body supporting portion 38. 
     Next, the first tab portions 66 are folded beneath the body support portion 38. Each first tab portion 66 includes a first panel portion 140 foldably connected to the body supporting portion 38, a second panel portion 142 foldably connected to the first panel portion 140 along adjacent edges at score line 143, and a third panel portion 144 connected to the second panel portion 142 along adjacent edges at score line 145. 
     The third panel portion 144 includes the prior described notches 78. The second and third tab portions 70 and 72 are likewise folded beneath the body supporting portion 38, and the first, second and third panel portions 140, 142 and 144 of each first tab portion 66 are folded so that notches 78 engage the notches 74 and 76 in the second and third tab portions 70 and 72. The first panel portion 140 of each first tab portion 66 is generally perpendicular the body supporting portion 38 when the first tab portion notches 78 are engaged with the second and third tab portion notches 74 and 76. Further, the second and third tab portions 70, 72 respectively are folded along respective score lines 150, 152 which are generally perpendicular a score line 154 about which the first panel portion 140 of the first tab portion 66 is folded with respect to the body supporting portion 38. 
     As is seen in FIGS. 6-8, each of the panel portions 46, 42 of each longitudinal supporting structure includes a portion of a notch 85 of a series of notches along and spanning the score line 40. Each of these notches 85, formed by folding a respective notch forming tab 84 about its score line 87, can accept a respective upstanding rib amongst a plurality of upstanding ribs in the bottom of a plastic liquid retaining tray 136 (FIG. 12), for example the plastic liquid retaining tray shown in U.S. Pat. No. Re. 34,846, assigned to the assignee of the present invention and hereby incorporated by reference herein as if fully set forth in its entirety. 
     As best seen in FIG. 9, the third panel portion 144 of the first tab portion 66 has a pair of lateral edges 151, 151. The free edge 32 of each of the second panel portions 42 is retained by one edge of the third tab portion pair of lateral edges 151, 151 thus retaining the longitudinal supporting structures folded. 
     As shown in FIG. 10, the carton top 14 may be unfolded back into its blank 32 form as shown in FIG. 3, and then refolded or erected into a floor structure 138 for placement in the bottom of the casket 26. The floor structure 138 is constructed by folding a lateral edge portion of the blank 32 defined by the score lines 104, 104 over beneath the planar floor portion 98 thereby providing longitudinal reinforcing structure 160 along each lateral edge of the floor portion 98 and narrowing the width of the floor structure 138 so as to fit within the assembled casket 26. Next, the structure 138 is folded about the transverse score lines 122, 122 in a lapped configuration to thereby shorten the floor structure 138 so as to fit within the casket 26 and also to provide torso reinforcing structure 162 to be generally located beneath the torso of a deceased supported atop the floor 138 thereby providing additional support beneath this region of concentration of weight of the body. 
     As shown in FIG. 11, the floor structure 138 is first placed in the bottom of the casket 26. In the casket of application Ser. No. 08/459,736, the floor structure 138 is placed atop a framework of horizontal slats 164 in lieu of the hardboard panel disclosed therein. Then the upright body support structure 130 is placed atop the floor structure 138. If desired, and as previously described, a plastic liquid retaining tray 136 may be disposed between the floor 138 and body support structure 130. 
     Referring now to FIG. 13, the carton top 14 is shown unfolded and refolded into an alternative form of casket floor structure 180. In this embodiment the floor structure 180 is constructed by folding the blank 32 along a longitudinal center score line 182, narrowing the width of the floor structure 180 so as to fit within casket 26 and providing a double-thickness floor. Next, the structure 180 is folded along each overlapped pair of score lines 183, 183 which are located longitudinally inboard of the score lines 106, 106, so as to fit within casket 26 and also to provide head and foot end reinforcing structure 184 to be generally located beneath the head and feet of a deceased supported atop the floor 180. 
     Referring now to FIGS. 14-19, there is shown a version of the carton top 200 which converts into a liquid retaining tray for installation into the casket at the destination point. Referring to FIG. 14, a cardboard blank 210 is coated with a suitable liquid impervious substance, such as Michelman liquid impervious coating. Blank 210 includes a pair of opposed lateral edges 212, 212 and a pair of opposed end edges 214, 214 defining a carton top ceiling 216 and a casket tray floor 218, respectively. Blank 210 further includes a first longitudinal pair of score lines 220, 220 defining a pair of carton top side walls 222, 222. The blank further includes a second longitudinal pair of score lines 224, 224 inboard of the first longitudinal pair of score lines 220, 220 defining a pair of liquid retaining tray side walls 226, 226. A first transverse pair of score lines 228, 228 define a pair of carton top end walls 230, 230, and a second transverse pair of score lines 232, 232 define a pair of liquid retaining tray end walls 234, 234. A score line 240 extends diagonally from each intersection 242 of the ends of the second longitudinal pair of score lines 224, 224 and the second transverse pair of score lines 232, 232 to each respective intersection 244 of the first longitudinal pair of score lines 220, 220 and the first transverse pair of score lines 228, 228. A longitudinal cut line 250 extends from each intersection 244 of the ends of the first longitudinal pair of score lines 220, 220 and the first transverse pair of score lines 228, 228 to a respective end edge 214 of the blank 210. A transverse cut line 260 extends from each longitudinal cut line 250 laterally partially outwardly defining a locking tab 270. A notch 280 in each end of the carton top end wall 228 is for accepting the locking tab 270, as will be subsequently described. An additional notch 290 is for additionally locking the tab 270 in the locked position, as will be subsequently described. 
     As shown in FIG. 16, the lid 200 is illustrated in its erected shape. To erect the carton lid as shown in FIG. 16, the corners are formed as shown in FIG. 15. The carton lid end walls 230 are first folded upwardly, then the carton lid side walls 222 are folded upwardly. The end portions 223 of the side walls 222 are folded inwardly about the score lines 228, and the locking tab 270 is first passed through slot 280 and is then tucked into slot 290. 
     To utilize the carton top 200 as a liquid retaining tray 300, shown erected in FIG. 19, the lid 200 is first unfolded and returned to its blank form as shown in FIG. 14. Then the tray side and end walls 226, 234 respectively are folded upwardly about respective score lines 224 and 232 respectively. The corners are formed by folding a portion of each end of each side and end wall 226, 234 respectively about the diagonal fold lines 240. Tab portions 302, 304 and 306 are folded along the respective score lines 232, 228 and 310 respectively. Tab 270 is inserted first through notch 280 and then into notch 290 to lock the tab 270 in place.
