Description

  The present invention relates to a nasal spray ejector.

  There has been proposed a nasal spray ejector comprising an attachment cap on which a pump is mounted and a nozzle member attached to the pump stem. (For example, see Patent Document 1)

The conventional nasal spray ejector is configured such that the nasal spray in the container body is ejected from the nozzle ejection hole by the pump mechanism by depressing the stem by depressing the nozzle member. At that time, since the nozzle stands on the center line of the container body that stores the nasal drops, the stem is pushed down by pressing the upper surface of the flange-like substrate protruding from the lower peripheral portion of the nozzle member.
