In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the vertical position of the discharge hole is located below the front end opening of the outer cylinder when discharging the contents, but it is sufficient that the contents can be discharged to the outside of the discharge container through the front end opening. Sometimes it may be at the same position as the opening of the outer tube. Further, the vertical position of the ejection hole may be located at the same position as or below the front end opening of the outer cylinder before the ejection head is pushed down.
Furthermore, the vertical position of the discharge hole may be positioned above the front end opening of the outer cylinder in any case before or after the discharge of the contents.
The discharge head has a pair of operation parts, but it is sufficient that the discharge head has at least one operation part that protrudes radially outward from the outer cylinder. In addition, the ejection head has an operation unit, and the slit portion is formed in the outer cylinder. However, as long as the ejection head can be moved downward with respect to the outer cylinder, an operation unit having another configuration may be used. .
The discharge container discharges the contents toward the affected part of the nasal cavity as an adherent part, but other parts may be used as the adherent part.
