Abstract
A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged front a nozzle portion by performing a discharge operation that presses the lid body toward an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber when the discharge operation is released. A coil spring that urges the lid body to an outside of the pump chamber is included in the pump chamber, a diameter of the coil spring is larger than a radius of the lid body, and a deformation amount of the lid body is equal to or more than ⅓ of a diameter of the lid body.

A dispenser, comprising:
- a pump chamber formed by a body including a depression and a lid body covering an opening of the body, wherein a first liquid in the pump chamber is discharged from a nozzle portion by performance of a discharge operation that presses the lid body into an inside of the pump chamber to deform the lid body, and a second liquid is caused to flow into the pump chamber by release of the discharge operation;
- and
- a coil spring that is arranged in the pump chamber and urges the lid body to an outside of the pump chamber, wherein
- a diameter of the coil spring is larger than a radius of the lid body, and
- a deformation amount of the lid body is equal to or more than ⅓ of a diameter of the lid body.
