Title:
MEASURING MECHANISM, AND CONSTANT-AMOUNT DISPENSER AND CONSTANT-AMOUNT APPLICATOR INCLUDING MEASURING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2021/049448
Kind Code:
A1
Abstract:
Provided is a measuring mechanism for measuring out and discharging a predetermined constant amount or any volume of a liquid composition, and a constant-amount dispenser and a constant-amount applicator including the measuring mechanism. A measuring mechanism is provided that comprises a base and a head forming a measurement space between the base and the head. The base and the head are configured to allow the volume of the measurement space to vary through predetermined operations of the head including a measuring operation that increases the volume of the measurement space and a discharging operation that decreases the volume of the measurement space. The base has a first flow channel through which the composition flows from the outside into the measurement space and a first check valve provided in the first flow channel. The head has a second flow channel through which the composition is discharged from the measurement space to the outside and a second check valve provided in the second flow channel. The sealing force of the first check valve of the base increases when the inside of the measurement space has positive pressure. Furthermore, a constant-amount dispenser and a constant-amount applicator are provided that include the measuring mechanism as a device that enables a user to readily measure out a compound.
