Abstract

A nozzle includes a mounting opening that is to be connected to an opening portion of a container, an outlet that jets liquid stored in the container, a side face that connects the mounting opening to the outlet, and a liquid storage portion that stores a part of the liquid stored in the container in the nozzle without jetting a part of the liquid from the outlet in a case where the liquid is to be jetted from the dispensing container, that is, in a case where the outlet faces downward in the direction of gravity.

First claim

What is claimed is:

1. A nozzle that comprises a mounting opening to be connected to an opening portion of a container, an outlet jetting liquid stored in the container, and a side face connecting the mounting opening to the outlet, the nozzle comprising:
a liquid storage portion that is provided in an interior space of the nozzle and stores the liquid in a case where the liquid is to be jetted,
a tubular portion of which an inside communicates with the outlet and which extends toward the mounting opening from the side face,
wherein the liquid storage portion is a space that is formed between an outer surface of the tubular portion and an inner surface of the side face and tapered toward the outlet, and

a guide structure portion that is provided on at least a part of an inner portion of the liquid storage portion and guides the liquid in the liquid storage portion toward the outlet from the mounting opening,
the guide structure portion being arranged circumferentially on the inner surface of the outlet and along an axial direction of the tubular portion.

2. The nozzle according to claim 1 ,
wherein the guide structure portion is a rib that is formed on at least a part of the inner portion of the liquid storage portion.

3. The nozzle according to claim 1 ,
wherein the guide structure portion is a groove that is formed on at least a part of the inner portion of the liquid storage portion.

4. The nozzle according to claim 1 ,
wherein the guide structure portion is a protrusion that is formed on at least a part of the inner portion of the liquid storage portion.

5. The nozzle according to claim 1 ,
wherein the guide structure portion is formed in a range from a position closer to the mounting opening than an end portion of the liquid storage portion facing the mounting opening to a position close to the outlet, in a direction toward the mounting opening from the outlet.

6. The nozzle according to claim 1 ,
wherein an entirety of the nozzle is made of a hydrophilic material.

7. The nozzle according to claim 1 ,
wherein at least a part of a portion where the liquid storage portion is formed is made of a hydrophilic material.

8. The nozzle according to claim 1 ,
wherein hydrophilization is performed on at least a part of a portion where the liquid storage portion is formed.

9. The nozzle according to claim 1 ,
wherein the nozzle is mounted on the container that stores a liquid sample for immunochromatographic measurement as the liquid.

10. A dispensing container comprising:
a container; and
the nozzle according to claim 1 .
