Abstract:
A discharge nozzle being located at the discharge opening of a flexible container being deformed by external pressure to discharge the content. Liquid channel in the nozzle is open at all times from the inlet on the container body side to the discharge opening and a part thereof is constituted of a gap passage defined by a plurality of faces. The gap passage has such dimensions that the content liquid stagnates under normal pressure due to its viscosity or surface tension and does not flow through the gas passage easily and the content can be discharged by pressing the container body. The discharge nozzle is provided with a function for preventing the content in the fluid channel thereof and the outer air from flowing back into the container body when the pressing force is released.
