WIPO Patent Application WO/2017/006924

A1

The purpose of the present invention is to provide a configuration, in a discharge part to be used in a discharge container, wherein sealing properties that make it possible to prevent contamination of a contained fluid being accommodated are realized, and a reduction in manufacturing costs can be effectively achieved. A discharge part (17) to be used in an eyedrop container (10) is provided with: a valve (30) configured from an elastic material and having a vertically elongated shape, the valve (30) having formed in the interior thereof a space (31) through which a contained liquid (100) passes, and having formed on the distal end thereof a slit (32) that reaches the space (31) from the exterior; and an orifice (20) inserted from the proximal-end side of the space (31), the orifice (20) having a portion formed such that the outer diameter thereof is greater than the inner diameter of the space (31). The proximal-end side of the valve (30) expands from the space (31) side due to the orifice (20), whereby a force is applied to the distal-end side of the valve along the direction in which the slit (32) is closed.
