A ORNEY SPLIT LID CASKET A primary object of this invention is to provide a novel split lid casket in which a hermetic seal is achieved by a dual seal arrangement consisting of a groove adapted to receive sealing compound outboard of gasket means on an uppermost periphery of the casket, and the lid sections including sealing surfaces for the gasket means and depending tongues for receipt in the grooves of the peripheral edge.

A further object of this invention is to provide a novel casket of the type aforesaid wherein adjacent transverse edge portions of the lid sections likewise include interengageable tongues and grooves and gasket means for seating engagement against a sealing surface.

Still another object of this invention is to provide a novel sealing system of the type heretofore described wherein the adjacent transverse edge portions of the lid sections are of a stepped configuration, and distal ends of the tongue of one of the lid sections being received in the groove of the casket peripheral edge.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claimed subject matter, and the several views illustrated in the accompanying drawings.

IN THE DRAWINGS FIG. 1 is a perspective view of a split lid casket constructed in accordance with this invention, and illustrates one lid section in its raised or open position having a depending tongue and a sealing surface for respective receipt into and sealing engagement with a groove and gasket means of a periphery of the casket.

FIG. 2 is an enlarged fragmentary view of the encircled portion of FIG. 1, and illustrates the manner in which a bridge or stepped portion of the split lid section isprovided with a groove and gasket means, and the relationship thereof in the closed position with the groove and gasket means of the casket peripheral edge.

FIG. 3 is an enlarged fragmentary sectional view taken generally along line 3-3 of FIG. 1 and illustrates a bridge or stepped portion of the head lid section and :1 depending tongue and sealing surface thereof.

FIG. 4 is a sectional view taken generally along line 4--4 of FIG. I and illustrates the sealing relationship of the gasket means and sealing surface and the tongue and groove of the casket periphery and the foot lid section.

FIG. 5 is a sectional view taken generally along line S--5 of FIG. 1, and illustrates a depending tongue and a sealingsurface of the head lid section.

FIG. 6 is an enlarged sectional view taken generally along line 6--6 of FIG. 1 and illustrates the alignment of gasket means and a groove of the foot lid section with the respective sealing surface and tongue of the head lid section of FIG. 5.

The present invention is directed to a novel casket, generally designated by the reference numeral 10 in FIG. I, which includes a body 11 defined by a pair of

side walls

12, 13, an end wall 14, and an opposite end wall (not shown). The end and side walls terminate at an uppermost peripheral edge 15 formed as a flange 16 (FIG. 2) which includes a pair of

grooves

17, 18. The

grooves

17, 18 are in concentric relationship to each other, and are ofa generally squared oval configurationas viewed in top plan, as is most readily apparent from the left-hand portion of the peripheral edge 15 illustrated in FIG. 1. Gasket means 19 in the form ofa sealing strip of rubber or similar sealing material is seated within the groove 18 while an organic thixotropic sealing material 20 is disposed in the groove 17.

The casket 10 includes a split lid generally designated by the reference numeral 25 which includes a head lid section 26 and a foot lid section 27. Both

sections

26, 27 are secured to the upper periphery of the side wall 12 by

conventional hinges

28, 28.

The head lid section 26, as is best illustrated in FIGS. 1, 3 and 5, includes

side walls

30, 31 and an end wall 32 defining a peripheral edge 33 which overlies and mates with the peripheral edge 15 of the body 11 when the head lid section is in its closed position. At the end of the head lid section 26 opposite the wall 32 is a recessed face 34 ofa generally shallow inverted U-shaped configuration. From the face 34 projects a like contoured depending tongue 35 inboard of which is a sealing surface 36. The tongue 35 extends not only along the face 34 but along the peripheral edge 33 of the head lid section 26, as is best illustrated in FIG. 1. Likewise, the surface 34 extends along the peripheral edge 33 to form a sealing surface for the underlying portion of the gasket 19 when the head lid section 26 is in its closed position.

The foot lid section 27 likewise includes

side walls

40, 41 and an end wall (not shown) which form a peripheral edge 42 identical to the peripheral edge 33 of the head lid section 26. A tongue 43 depends from the peripheral edge 42 along both

side walls

40, 41 and the end wall (not shown) and thus the tongue 43 matches in shape and positioning that portion of the tongue 35 on the peripheral edge 33 of the head lid section 26. Thus, the combined portions of the tongues along the

peripheries

33, 42 of the head and

foot sections

26, 27, respectively, define essentially a continuous tongue which is received in the groove 17 atop the sealing compound 20 disposed therein. Thus a double seal effect is achieved between the lid 25 in its closed position relative to the entire peripheral edge 15 of the casket body 11.

A transverse double seal is also effected with the lid in its closed position by providing the foot lid section 27 with a bridge or stepped transverse edge portion 44 having an inverted shallow generally U-shaped surface or step 45 (FIG. 6) and an inboard shoulder or step 46 of a similar configuration which is provided with a like shaped groove 47 receiving thixotropic sealing material 20. By viewing FIGS. 5 and 6 simultaneously, it will be noted that the sealing face 36 is in alignment with gasket means 48 seated upon the surface 45 while the portion of the tongue 35 depending from the face 34 is in alignment with the groove 47. Moreover, as is best illustrated in FIG. 2, respective

opposite ends

50, 51 of the steps 45, 46 terminate contiguous the

respective grooves

18, 17, while the gasket 48 is folded under the continues along the ends 50, as shown best in FIG. 4. Thus, upon the closing of the lid 26 there is not only achieved sealing between the tongue 35 and the groove 47, along with its associated sealing material 20, and between the sealing surface 36 and the gasket 48, but additionally the underlying portion of the gasket 48 at the

ends

50, 50 effects'the seal with the gasket 19 and the distal ends or corners (unnumbered) of the tongue 35 also enter the groove 17 at the points at which the

grooves

17, 47 intersect (FIG. 2). Thus, in the closed position of the lid 25 there is not only a double seal about the entire peripheral edge of the casket 10, but a like double seal curves along the transverse inner section of the

lid sections

26, 27.

From the foregoing the dual sealing affords the user the advantage that if one sealing system should result in an unforeseen failure, there is the assurance that the second sealing system will offer the protection that is desired. Moreover, the dual seal results in a permanent closure of the casket 10 in a short time after the lid has been closed because of the quick-setting characteristics of the sealing material 20. Moreover, by providing two sealing systems either individually to the exclusion of the other is available.

While preferred forms and arrangements of parts have been shown in illustrating the invention, it is to be clearly understood that various changes in details and arrangements of parts may be made without departing from the spirit and scope of the disclosure.
