Abstract: 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.

Abstract: Provided are a measuring mechanism for measuring a predetermined fixed amount or an arbitrary amount of a liquid composition and discharging it, and a quantitative dispensing container and a quantitative applicator including such a mechanism. A measuring mechanism is provided that includes a base and a head defining a measurement space between the base and itself, the base and the head 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.
