Trigger-type liquid sprayer

A trigger-type liquid sprayer comprising:

• a sprayer body mounted on a mouth part of a container body, in which a liquid is accommodated, via a mounting cap;
• and
• a nozzle part mounted on the sprayer body and having a spray hole configured to spray a liquid,
• wherein the sprayer body includes:
• a longitudinal supply cylinder part configured to suction up the liquid in the container body;
• a trigger mechanism having a trigger part disposed to be movable rearward in a forward biased state, and configured to cause the liquid to flow from an inside of the longitudinal supply cylinder part toward the spray hole according to rearward movement of the trigger part;
• an invertible adapter disposed inside the mounting cap, disposed below the longitudinal supply cylinder part along an axis of the longitudinal supply cylinder part, and connected to the longitudinal supply cylinder part;
• a storage cylinder disposed inside the mounting cap, disposed below the invertible adapter along the axis, connected to the invertible adapter, and extending in an upward/downward direction;
• and
• a storage plunger provided in the storage cylinder to be movable downward in an upward biased state,
• the longitudinal supply cylinder part includes:
• a first flow path through which a liquid flows toward the spray hole according to rearward movement of the trigger part;
• and
• a second flow path through which part of the liquid flowing through the first flow path flows toward the storage cylinder, and
• the invertible adapter includes:
• an adapter main body configured to define a first space and a second space, the first space configured to bring an inside of the container body in communication with an inside of the first flow path through an upright introduction port, and the second space configured to bring an inside of the container body in communication with the first space through an inverted introduction port;
• a switching valve configured to, in a state in which the sprayer body is mounted on the container body, block communication between the first space and the second space when the container body is upright and bring the first space and the second space in communication with each other when the container body is inverted;
• and
• a relay flow path configured to bring the second flow path and an inside of the storage cylinder in contact with each other.
