Lovely coffins are expensive and their fine wood and brass fittings are seen only briefly before interment. Funeral homes are notorious for gouging berieved families to the tune of several thousand dollars for their loved ones' final resting vessels. So it is a notable acheivement when a blow is struck for the consumers, who after all stand to inherit the difference. The reusable coffin is a stripped-down model, just an ornamental shell without internal padding. It features spring-loaded pins inside supporting a plastic capsule that actually holds the corpse.
Pall bearers carry the coffin to the grave.
Then the pins are retracted, dumping the capsule in the actual grave. The coffin shell is removed for future re-use. The capsule has the additional advantage of being the only waterproof casket on the market. It doesn't look like a Tylenol. The dead would certainly salute Barker and co-inventor Roy Minton.
