Abstract

PURPOSE:To provide a discharge valve which has check valve function and a very thin section and minimizes size, by a method wherein a valve body formed with an umbrella-shaped inner valve part and a coverform outer valve part is contained in a valve box to form a discharge valve. CONSTITUTION:A valve body 2 is formed with an umbrella-shaped inner valve part 21 to form an inner air inflow space 4 and a coverform outer valve part 22 to support the top part of the inner valve part 21, and the valve body 2 is contained in a valve body containing recessed part 1b of a valve box 1 to form a discharge valve. This constitution provides a discharge valve which holds a doubly closed state, has check valve function and a thin section, and minimizes size.
