Abstract
The base section of a burial casket supports an internal latch mechanism which is effective to engage keepers projecting downwardly from a pivotally supported cover section and to draw the cover section firmly against a resilient gasket member disposed between the base and cover sections. The gasket member is molded as a one-piece rectangular frame and includes parallel spaced peripherally extending sealing portions, the inner portion having an inverted U-shaped wall configuration and the outer portion having generally a V-shaped wall configuration. The latch mechanism includes a rotary actuator having an externally threaded coupling portion projecting to a circular opening within the front wall of the base section. A resilient sealing ring or grommet is mounted within the opening, and a cap-like closure member includes a tubular coupling portion which projects through the opening and threadably engages the coupling portion of the rotary actuator. When the closure member is tightened, the grommet is compressed between the base section and an annular surface on the closure member. When the closure member is released, air is permitted to flow through the opening to equalize the press…
