Abstract: Cooking apparatus includes apparatus to support food to be cooked. A housing surrounds a portion of the support apparatus and defines a portal through which food may be passed into the housing. A fireplace is disposed in the housing to support a fire that produces heated gas for cooking food. The fireplace may include a solid fuel burning grate to support solid fuel used as a flavor enhancing substance to the food being cooked with the grate having a body with apertures through which hot coal is discharged. A hot coal supporting device is disposed beneath the grate to receive the hot coals discharged from the solid fuel burning grate and has a body with apertures through which ash is discharged. An ash bin is disposed beneath the hot coal supporting device to receive the discharged ash. A heated gas passageway is provided in the housing to place the heated gas in fluid communication with an environment outside of a building in which the housing is disposed.

Abstract: A blade holder and nozzle assembly connectable to a flexible container closure element such that when the blade holder and nozzle assembly is connected to the flexible closure a circular opening is formed in the flexible closure and surfaces on the blade holder and nozzle assembly and on the flexible closure are urged into sealing relation. The assembly comprises a hollow, tubular body having a shoulder extending around the interior thereof dividing the interior of the body into a threaded bore in the lower end of the body and a nozzle in the upper end of the body. A single cutting blade having a pointed end and a single cutting edge is secured to the shoulder and extends into the threaded bore such that as the body is threadedly secured to a flexible closure element, the cutting blade pierces the upper surface of the closure element and as the body is rotated the blade cuts a circular opening in the upper end of the closure element.
