Claims15
A trigger-type liquid ejector comprising:
- a nozzle member in which an ejection hole for ejecting a liquid is formed;
- an ejector main body in which the nozzle member is mounted;
- and
- a mounting cap which mounts the ejector main body in a mouth portion of a container body accommodating the liquid,
- wherein the ejector main body includes
- a vertical supply tube portion which suctions up a liquid inside the container body, and
- a trigger mechanism which has a trigger portion provided so as to be movable rearward in a forward biased state, and which causes a liquid to flow from an inside of the vertical supply tube portion toward the ejection hole side in response to rearward movement of the trigger portion, and
- the mounting cap includes a restriction portion which is close to or abuts on the ejector main body in a vertical direction and restricts relative displacement between the mounting cap and the ejector main body.

- an ejector main body which is mounted in a container body accommodating a liquid;
- and
- a nozzle member which is mounted in the ejector main body, and in which an ejection hole for ejecting a liquid is formed,
- wherein the ejector main body includes
- a vertical supply tube portion which suctions up a liquid inside the container body,
- a connection tube portion which extends from the vertical supply tube portion, and which has an opening portion opening to an outside of the ejector main body,
- a trigger mechanism which has a trigger portion provided so as to be movable rearward in a forward biased state, and which causes the liquid to flow from the vertical supply tube portion toward the ejection hole side through an inside of the connection tube portion in response to rearward movement of the trigger portion,
- a storage cylinder in which a supply hole communicating with the inside of the connection tube portion is formed, and into which the liquid that has passed through the inside of the vertical supply tube portion and the inside of the connection tube portion is supplied through the supply hole in response to rearward movement of the trigger portion, and
- a storage plunger which is provided inside the storage cylinder so as to be movable in an axial direction along a center axis of the storage cylinder, which moves toward one side in the axial direction along with supply of a liquid to the inside of the storage cylinder, and which is biased toward the other side,
- the connection tube portion is provided with a closing plug which is mounted so as to close the opening portion, and
- the closing plug includes
- a plug main body which is fitted to the inward side of the connection tube portion, and which closes the opening portion, and
- an outer tube which is formed to extend over a whole circumference of the connection tube portion in a manner of surrounding the connection tube portion from an outward side in a radial direction, and which is fitted to an outward side of the connection tube portion over the whole circumference.
