A lithographic projection apparatus includes a substrate table that holds a substrate, a projection system that projects a patterned beam of radiation onto the substrate, and a liquid confinement structure that confines a liquid in a space between the projection system and the substrate, the substrate, the substrate table, or both, to form a part of a boundary of the space. There has been an increasing demand for a cooking-and-preservative food preparing apparatus. Contents of the bottle are gravity-dispensed so as to eliminate repeated squeezing of bottle to discharge contents. Further, the electrodes for the electric discharge, which are formed at the upper and lower electrodes, utilize flat plate electrodes.
