摘要
In a discharge nozzle which is to be provided at a discharge opening of a flexible container to be deformed by external pressure to discharge contents, a liquid channel in the nozzle is penetrated at all times from an inlet on the side of a container body to a discharge opening and is partially composed of a gap channel defined by a plurality of faces, and the gap channel is of such dimensions that a contents liquid stagnates under normal pressure due to its viscosity or surface tension and does not easily flow therethrough, whereby the discharge nozzle is provided with a function for preventing a backflow of contents wherein the contents can be discharged by pressing the container body at the time of discharge, while the contents in the liquid channel of the discharge nozzle and the outer air are prevented from flowing back into the container body when the pressing force is released.
