DETAILED DESCRIPTION OF THE DRAWINGS:

In considering various of the figures of the draw-ings, it should be noted that the corrugations of the cor-rugated fiberboard pieces employed in the fabrication of the variou~ forms of casket lid disclosed are not illus-trated in various o~ the sectional views, such as Figures 3, 4, 10, 11, 13 and 14. ~owever, as to each form, enlarged fragmentary sectional views, such as Figures 5, 6, 7, 9, 12 and 15, are included in order to illustrate the construc~
tion of the fiberboard piPces employed and the vri ntation of the corrugations of each piece employed.

~2~

As above indicated~ the present invention is con-cerned with the construction of the lid of the casket, and the various forms of lid disclosed may be employed with a shell ox base of caskets of a variety of forms, it being contemplated that the corrugated fiberboard lids of the present invention will normally be employed in association with a shell or base also formed of corrugated fiberboard.
Such a shell or base is shown in the fi~ures illustrating the first embodiment. Thus, in Figures 1, 2, 3, 4 and 10, the casket shell is shown as having inclined side walls 17 and inclined end walls 18. In a ty~ical embodiment of the shell, framing elements may be provided as indi~ated at 19 on the lower edges of the shell and may also be pro-vided as indicated at 20 around the upper edges of the shell. The side and end walls 17 and 18 are desirably formed of corrugated fiberboard in a manner which need not be considered herein, and the framing elements 19 and 20 may be ~ormed of wood.

The shell of the casket is also desirably provided with handgrip rails such as indicated at 21 secured to the walls of tbe shell by appropriate brackets 2~ in a manner which need not be considexed herein.

Turnlng now to the embodiment of the lid as shown in Figures 1 to 10, it will be seen that the lid disclosed in those figures includes a sheet or compcnent extended subs~antially throughout the area o the lid, this sheet having a central upwardly domed portion 23 and being formed of corrugated fiberboard, for instance, of the type illus-trated in FigurPs 6 and 7, having upper and lower sheets with an intervening corrugated layer. Such a sheet is com~
monly referred to as single-wall fiberboard. As will be seen from Figures 6 and 7, this sheet or layer 23 is posi tioned so that the corrugations thereof extend transversely of the lid.

The sheet 23, in addition to being domed in the central region, also has bevel edg~ portions indicated in various of the figures at 23a, which are arranged not only along the side edses o the lid but also at the ends thereof.

In each of the four corners of this top sheet 23 of the lid, cuts are made as indicated at 24 in Figure

2~ and tapered portions of the klank form of which the lid is fabricated are cut out at the corners so that when the side and end portions of the lid are flexed to the curvature and angular configuration indicated in Figures 3 and 4, the tapered cut-out regions will ~e closed.

The specific configuration of the lid in the end regions, and particularly in the regions where the end sur-faces join the side surfaces, may vary somewhat, but it is contemplated according to the present invention that at least the major port.ion of khe lid be formed by a prin-cipal lid component extended throughollt the width of the lid and throughout at least most of the length of the lid and having the corrugations thereof extended in a direction transversely of the lid throughout not only the central domed region but also throughout the bevelled side edge portions thereof.

A5 seen particularly in Figures 3 and 4, the marginal edge portions of this principal lid component lQ identified by the numeral 23 are folded to engage marginal edge framing elements 25 desirably formed of wood~ the corrugated sheet material beîng secured to the edge framing 25 as by staples such as indicated at 26 in Figures 3 and 4.

The lid further includes another panel or layer connected with the layer 23 at least in the central region thereof. In the first embodiment (see particularly Figures

3, 4, 6 and 7), this additional layer is indicated at 27.
This component preferably comprises what is known in the art as single face corrugated fiberboard, being formed oE
only a ~ingle plain layer and a single corrugated piece adhesively boarded to each other. The corrugated layer of this piece is desirably adhesively bonded to one of the sur~ace layers of the single wall sheet 23 described above.

:~2~

This re]ationship is shown in Figures 6 and 7; and from Figures 6 and 7, it will Eurther be noted that the corru-gations of the single face piece 27 and the corrugations of the single wall piece 23 extend in different directions.
Preferably, as shown, the corrugations of the single wall 23 extend transversely of the lid, and the corruyations of the single face 27 extend longitudinally of the lid.
This relationship is of importance in contributing rigidity and strength to the lid structure. The inner single face reinforcement layer desirably is of width approximating the width of the central or domed portion of the layer 23, but the reinforcing layer is not needed at the bevel edge regions 23a. In addition, such reinforcement need not be applied at the terminal end porkions of the lid.

As seen particularly in Figures 2, 3, 4, 8 and 9, the lid of the first embodiment also incorporates braces in the form of transversely extended bridges, which are also formed o~ corrugated fiberboard. These bridges are identified in the drawings by the numeral 28, and as best seen in Figure 8, there is a transverse bridge 28 located ~ear each end of the lid; and in the central region of the lid, a plurality o such transverse bridges are arranged in juxtaposed position.

g4~
From Figures 5 and 9~ it will be seen that the bridges are also formed of corrugated fiberboard components.
In the embodiment of Figures 1 to 10, inclusive, the com~
ponents employed for the bridges comprise triple-wall corru-gated fiberboard elements. Thus, in Figure 5, it will be seen that the component there shown comprises four plain sheets separated by but adhesively bonded to three indi vidual corrugated layers.

In the central region where three bridges are included, as will be seen from Figure 9, there are three side-by-side triple-wall corrugated components.

In the case of all of the bridges 28, either at the end or in th~ central region of the lid, the corruga-tions of the components used extend in a direction perpen-dicular to the lid, and this is preferred in order to maxi-mize the bracing contributed by the bridges. It should also be noted that with the corrugations extended v~rtically in the bridges tand~ thus, generally perpendicularly to the li~d~, and with the corruga~ions of the layers 23 and 2a 27 extended respectively transversely of the lid and longi-tudinally of the lid, the combined effect of the three dif-ferent components interconnected with the corrugations extended in three different directions maximizes the strength and thereby provides for high strength with a minimum of material.

~2~

As has been pointed out above, the lid provided by the presen~ invention may, if desired, be cut in the mid-region in order to prov.ide two lid panels. As shown in Figure 10, this is desirably effected by cutting in the central region of the centxal one of the three transverse bridges 28 employed in the central region. Thus, as seen in Figure 10, each portion of the lid includes one of the bridges 28 and a portion of the central bridge 2.8a.

Whether the lid is mounted on the casket as one 1~ piece or as two pieces~ the lid is preferably mounted by means of hinges as diagrammatically indicated at 29 in Figure 10.

After construction of the completed casket and lidJ fabric covering may be appliedr a portion of such a covering being indica~ed at 30 in Figure 10.

The alternative embodiment shown in ~igu~es 11 and 12 includes a main single-wall layer 31 extended substan-tially throughout the length and width of the lid, but in this instance, the central portion of the lid is not domed 2Q but is flat. However, bevel edges 31a are desirably pro-vided not only on the longitudinal edges of the lid but also at the ends thereof. The inner panel 32, shown in Figure 11, extends throughout the central region of the :~2~
component 31. As in the embodiment of Figures 1 to 10~
it is contemplated that the corrugations of the single-wall layer 31 be extended transversely of the lid, and the corru-gations of the single-face layer 32 be extended longitud-inally of the lid.

The lid of the embodiment shown in Figures 11 and 12 also includes transverse bridges 33 and, as seen in Figure 12, these bridyes are formed of double-wall corru-gated fibPrboard comprising three planar sheets and two 1~ corrugated layers. As in the first embodiment, the bridges are adhesively bonded to the lid. The corrugations of this component in Figure 12 extend vertically, i.e., transversely to the general plane of the lid, thereby providing the inter-bracing effect above described in combination with the trans-verse and longitudinal corrugation extension provided in the components 31 and 32 of which the lid is formed~

Turning now to the third embodiment, as shown in Figures 13 to 16, it will be seen that the lid here shown includes as one component a single-wall layer 34 having bevel edge portions 34a along the side edges and also along the end edges thereof. This component is formed of single-wall corrugated fiberboard of the kind above described, with the corrugations extended transv~rsely of the lid t as in component 23 of the first embodiment and component 31 of the second embodiment.

In the embodiment of Figures 13 to 16, the addi-tional component incorporated in the lid with corrugations extending longitudinally of the lid comprises a layer 35 formed of double-wall corrugated fiberboard, as seen particu-larly in Figure 15. It will be noted that the corrugations of this component extend lengthwise of the lid, i.e., in a direction perpendicular to the corrugations of the com-ponent 34. The component 35, as seen in Figures 13 and 14, is domed transversely and also has domed end portions in the end regions of the lid. Preferably, the end regions are formed from a blank of tapered plan form so as to fit into recessed cutouts at the ends of the components 35 and 34a along lines indicated at 36 in Fiyure 16. The end por-tions, and the central part of the component 35, are also adhesively secured to each other~ At the edges of the component 35 along the lines of junction with the component 34, the inn2r layers of the double-wall fiberboard employed may be cut back and the outer planar layer folded under as indicated at 35a in Figure 15, in order to provide an appreciable surface area for adhesivc bonding between the edges of the component 35 and the edges of the component 34.

As in the first and second embodiments, transverse reinforcement bridge~ 36 are also provided in the embodiment in Figures 13 to 16, and these bridges are preferably applied and adhesively bonded in the end regions of the lid and also i.n the central regionL In the preferred construction, these bridges are desirably formed of triple-wall corrugated fiberboard in the manner indicated .in Figure 9. It is also contemplated that in the third embodiment, three triple-wall bridges will be employed in the central region in order to acilitate cutting of the lid into two halves wherever that is desired, while still retaining effective reinforce-ment for the two panels of the lid~

As in the first and second embodiments, in the embodiment of Figures 13 to 16, the corrugations of ~he bridges extend vertically and, thereby, in combination with the transverse and longitudinal extension of the corruga-tions in the layers 34 and 35, provide the desired three-way reinforcement achieved as a result of the tbree-way extension of corrugations in the three principal components of the lid. In all cases, all of these components are adhesively bonded to each other and the resultant structure has great strength when considered in relation to the quan-~ tity and weight of materials employed.
