  • cover portion 240 is shown in the open position in Figs. 10 and 11, and the cover portion 240 is shown in the closed position in ghost outline in each of Figs. 10 and 11, to simplify illustration thereof.
  • the cover portion 240 is pivoted upwardly to close the aperture 228.
  • the cover portion 240 preferably is latched to, or otherwise suitably releasably attached to, the body portion 240 at a top end 227 thereof.
  • the cover portion 240 preferably is latched to the body portion at the top end 227, to close the aperture so that objects (not shown) in the chamber 226 may be heated, if desired.
