The contents are discharged from the discharge port, the nozzle cylinder includes a flange portion protruding radially outward, and the overcap has a flange portion protruding radially outward. In addition, the flange portion of the overcap is placed on the upper surface of the flange portion of the nozzle tube, and is recessed in a step shape on the lower surface of the inner peripheral portion of the flange portion of the overcap. A stepped portion spaced from the upper surface of the stepped portion is formed, and the vent is opened toward the inside of the stepped portion .

  With such a feature, since the outside air flows into the overcap through the vent, the air permeability inside the overcap is improved. In addition, since the above vent is formed between the nozzle cylinder and / or between the nozzle cylinder and the overcap, dust or the like is difficult to enter the overcap through the vent, and in the vent. Dust and dirt are less likely to clog.

  Further, in the discharge container according to the present invention, the discharge port is disposed on an upper end surface of the nozzle cylinder, and a seal convex portion that closes the discharge port protrudes on a lower surface of the top wall portion of the overcap. It is preferable to be provided.

  Thereby, since the discharge port is closed by the seal convex portion, the contents are prevented from leaking from the discharge port, and the discharge port is difficult to dry.

  Further, in the discharge container according to the present invention, the overcap is made of an elastically deformable soft material, and the top wall portion is pressed by the nozzle cylinder via the seal convex portion and elastically deformed in the axial direction. It is preferable.

  Thereby, the seal convex part is pressed against the discharge port by the elastic force of the top wall part made of a soft material.

According to the discharge container of the present invention, the outside air flows into the overcap through the vent and the air permeability inside the overcap is improved, so that the surface of the nozzle cylinder is easily dried. As a result, it is difficult for germs to propagate on the surface of the nozzle cylinder, and the nozzle cylinder can be maintained in good sanitary condition.

Each is formed perpendicular to the axis O. On the other hand, the top wall portion 160 in the state where the overcap 106 is attached to the nozzle cylinder 5 bulges upward as the upper end surface of the nozzle cylinder 5 presses the seal convex portion 165 upward. It is elastically deformed in a circular arc shape.

  The fitting tube portion 163 is a cylindrical tube portion extending along the axial direction with the axis O as the center axis. The flange portion 52 of the nozzle tube 5 is disposed inside the fitting tube portion 163, and the fitting tube portion 163 is undercut fitted to the longitudinal portion of the flange portion 52 of the nozzle tube 5. Has been. On the other hand, as shown in FIGS. 4 and 5, a gap is formed between the outer edge in the short direction of the flange portion 52 of the nozzle cylinder 5 and the inner peripheral surface of the fitting cylinder portion 163.

Further, a vent hole 155 is formed between the flange portion 52 of the nozzle cylinder 5 and the flange portion 162 of the overcap 106 to communicate the outside of the overcap 106 with the inside of the overcap 106.
