Claims (5)

A head portion having an introduction passage communicating with the nozzle hole is provided therein, and the head portion is pushed down in a state of being attached to the mouth portion of the container body, thereby allowing liquid in the container body to pass through the introduction passage. A discharger for discharging from a hole,
The introduction path extends along a direction intersecting the vertical direction, and an opening formed on one end side thereof is the nozzle hole,
A communication hole extending in the vertical direction and communicating with the introduction path is formed in the head portion, and an inner cylinder member that slides in the vertical direction is provided in the communication hole. A first elastic member that biases the head portion upward with respect to the inner cylinder member is provided between the inner cylinder member,
The upper end opening edge of the inner cylinder member straddles the upper end opening edge from the portion located on the other end side in the introduction path with the upper end opening of the inner cylinder member opened, and the introduction path A lid plate extending to one end of the inside is extended,
This lid plate closes the opening of the communication hole in the introduction path in a standby state before the head part is pushed down, and when the head part is pushed down with respect to the inner cylinder member, and when the depression is released Further, a discharger characterized in that it can be moved in the vertical direction in the introduction path. The dispenser according to claim 1 , wherein
A discharger, wherein a gap in an up-down direction between an upper end opening edge of the inner cylinder member and the lid plate is gradually increased from the other end side to the one end side of the introduction path. The dispenser according to claim 1 or 2 , wherein
A liquid piston linked to the head portion, and a liquid cylinder in which the liquid piston slides in the vertical direction.
The liquid is transferred to the introduction path and discharged from the nozzle hole by compressing the liquid in the liquid cylinder by pushing down the head part in a state of being attached to the mouth part of the container body. Dispenser characterized by. The dispenser according to claim 3 , wherein
In the liquid cylinder, a valve body that can be seated and separated is provided at a lower end opening of the cylinder, and a second piston that urges the liquid piston upward between the valve body and the liquid piston. An ejector comprising an elastic member, wherein the second elastic member has a higher upward biasing force than the first elastic member. The dispenser according to claim 3 or 4 , wherein
An air cylinder in which an air piston linked to the head portion slides in the vertical direction;
A gas-liquid mixing chamber in which the liquid from the liquid cylinder and the air from the air cylinder merge;
A foaming member installed between the introduction path and the gas-liquid mixing chamber,
The liquid in the liquid cylinder and the air in the air cylinder are compressed by pushing down the head part in a state of being attached to the mouth of the container body, thereby transferring these liquid and air to the gas-liquid mixing chamber. A discharger characterized in that after being merged and foamed through a foaming member, it passes through the introduction path and is discharged from the nozzle hole.
