Title:
CONTAINER DISPENSING AT FIXED QUANTITY
Document Type and Number:
WIPO Patent Application WO/2021/115138
Kind Code:
A1
Abstract:
In a container dispensing at a fixed quantity, operations are performed on a valve sleeve (200) to control opening or closing of a liquid inlet control structure (3), such that a liquid storage cavity (2) communicates with or is isolated from a fixed-quantity cavity (1). When the liquid storage cavity (2) communicates with the fixed-quantity cavity (1), a liquid in the liquid storage cavity (2) flows into the fixed-quantity cavity (1). Once a required quantity is reached, an operation is performed on the valve sleeve (200) to control the liquid inlet control structure (3) to close, thereby isolating the liquid storage cavity (2) and the fixed-quantity cavity (1). The liquid in the fixed-quantity cavity (1) is discharged from a liquid dispensing opening (11). The liquid storage cavity (2) is provided inside the fixed-quantity cavity (1). Alternatively, the fixed-quantity cavity (1) is provided inside the liquid storage cavity (2). The container has reasonable design and a simple structure, occupies a small space, is convenient to use, and can dispense at a fixed quantity.
