A mechanism for measuring an amount of a liquid composition and discharging it, and a quantitative dispensing container and a quantitative applicator including such a mechanism including a base and a head defining a measurement space therebetween. The base and the head are configured to be capable of changing the volume of the measurement space in response to a predetermined operation of the head including a measurement operation for increasing the volume of the measurement space and a discharge operation for reducing the volume of the measurement space. The base includes a first passageway for allowing the composition to flow from the outside into the measurement space, and a first check valve located on the first passageway. The first check valve of the base increases its sealability if there is a positive pressure in the measurement space.

An airless container includes a cylindrical container body storing a contained material, which is a fluid, in an airtight state, and a pump attached to an upper edge portion of the container body and configured to externally discharge the contained material. The airless container further includes a bottom lid that closes a lower opening portion of a container bottom portion of the container body, and a piston in the container body between the pump and the bottom lid, which is slidable in the container body in an airtight state. The piston includes a flexible piece that is deformable in a portion that comes into contact with the bottom lid. The flexible piece is deformable against the sliding of the piston toward the bottom lid.
