Abstract

A novel technique for the fabrication of a casket dome lid from, for example, Smooth-One-Side (“S1S”) hardboard is disclosed. The invention is also directed to the fabrication of a casket lid which has a domed configuration both in the lateral and longitudinal directions of the lid. The method comprises the steps of providing a lid blank having a first end, second end, and a central region; providing a pair of diagonal voids oriented at corners of the first end of said blank and extending inward toward the central region; placing the lid blank in a vacuum fixture; and flexing the lid blank into a domed configuration via the vacuum fixture, such that the blank is domed in both a longitudinal and a transverse direction.

First claim

What is claimed is:

1. A casket lid comprising:
a domed lid blank comprising a plurality of trim edges around a periphery of the blank and having a first end, a second end, and a central region, the blank being domed in both a longitudinal direction and a transverse direction;
a plurality of frame members attached to the plurality of trim edges;
a support laminate comprising a plurality of tabs, the support laminate being fixed to the blank, wherein the plurality of tabs are secured to the plurality of frame members; and
a support bridge attached to the domed lid blank, wherein the support bridge comprises a plurality of notches that extend under the plurality of frame members, wherein a fastener protrudes from each notch on the support bridge into a longitudinal frame member of the plurality of frame members.

2. The casket lid according to claim 1 , further comprising a header bridge attached to the central region of the domed lid blank.

3. The casket lid according to claim 2 , wherein the support bridge is attached to the lid blank between the first end of the lid blank and the header bridge.

4. The casket lid according to claim 1 , wherein the domed lid blank comprises a first domed lid blank half comprising a header bridge attached to the second end of the first domed lid blank half, and further comprising:
a second domed lid blank half comprising a second plurality trim edges around a periphery of the second lid blank half and having a first end, a second end, and a central region, the second domed lid blank half being domed in both a longitudinal direction and a transverse direction;
a second plurality of frame members attached to the second plurality of trim edges;
a second support laminate comprising a second plurality of tabs, the second support laminate being fixed to the second domed lid blank half, wherein the second plurality of tabs are secured to the second plurality of frame members; and
a second header bridge attached to the second end of the second domed lid blank half;
wherein the first domed lid blank half and the second domed lid blank half are adapted to be attached to a casket shell with the second end of the first domed lid blank half facing the second end of the second domed lid blank half.

5. The casket lid according to claim 4 , further comprising a second support bridge attached to the second domed lid blank half between the first end of the second domed lid blank half and the second header bridge.

6. The casket lid according to claim 5 , wherein the second support bridge comprises a second plurality of notches that extend under the second plurality of frame members, wherein a fastener protrudes from each notch on the second support bridge into a longitudinal frame member of the second plurality of frame members.

7. The casket lid according to claim 4 , wherein the plurality of frame members comprises at least two first longitudinal frame members and a first transverse frame member and the second plurality of frame members comprises at least two second longitudinal frame members and a second transverse frame member.

8. The casket lid according to claim 7 , wherein the header bridge is attached to the at least two first longitudinal frame members and the second header bridge is attached to the at least two second longitudinal frame members.

9. The casket lid according to claim 1 , further comprising rim members attached to the periphery of the lid blank.

10. The casket according to claim 1 , further comprising a plurality of rim members attached to the periphery of the domed lid blank, wherein the plurality of rim members are attached along an edge of the first end and along sides of the central region of the domed lid blank.

11. A casket lid comprising:
a domed lid blank comprising a first domed lid blank half and a second domed lid blank half, the domed lid blank being domed in both a longitudinal direction and a transverse direction;
wherein the first domed lid blank half comprises:
a first plurality of trim edges around a periphery of the first domed lid blank half and having a first end, a second end, and a central region;
a first plurality of frame members attached to the first trim edges of the first domed lid blank half; and
a first support laminate comprising a first plurality of tabs, the support laminate being fixed to the domed lid blank, wherein the first plurality of tabs are secured to the first plurality of frame members;
a first header bridge attached to the second end of the first domed lid blank half; and
a first support bridge attached to the first domed lid blank half between the first end and the first header bridge, wherein the first support bridge comprises a first plurality of notches that extend under the first plurality of frame members, wherein a fastener protrudes from each notch on the first support bridge into a longitudinal frame member of the first plurality of frame members.

12. The casket lid of claim 11 , wherein the second domed lid blank half comprises:
a second plurality of trim edges around a periphery of the second domed lid blank half and having a first end, a second end, and a central region;
a second plurality of frame members attached to the second plurality of trim edges of the second domed lid blank half;
a second support laminate comprising a second plurality of tabs, the second support laminate being fixed to the second domed lid blank half, wherein the second plurality of tabs are secured to the second plurality of frame members; and
a second header bridge attached to the second end of the second domed lid blank half; and
a second support bridge attached to the second domed lid blank half between the first end and the second header bridge, wherein the second support bridge comprises a second plurality of notches that extend under the second plurality of frame members, wherein a fastener protrudes from each notch on the support bridge into a longitudinal frame member of the second plurality of frame members,
wherein the first domed lid blank half and the second domed lid blank half are adapted to be attached to a casket shell with the second end of the first domed lid blank half facing the second end of the second domed lid blank half.

13. The casket lid according to claim 11 , wherein the first plurality of frame members comprises at least two longitudinal frame members and a transverse frame member.

14. The casket lid according to claim 12 , wherein the first header bridge is attached to the at least two longitudinal frame members.

15. A casket lid comprising:
a domed lid blank comprising a first domed lid blank half and a second domed lid blank half, the domed lid blank being domed in both a longitudinal direction and a transverse direction;
