Title:
QUANTITATIVE CONTAINER CONVENIENT FOR BACKFLOW
Document Type and Number:
WIPO Patent Application WO/2021/139802
Kind Code:
A1
Abstract:
A quantitative container convenient for backflow. By operating an upper cover (3) to move with respect to a base (2)/container body (1), opening or closing of a liquid inlet control structure (7) and a liquid outlet control structure (5) can be controlled, so that an inner cavity of the container body is communicated with or separated from a quantitative cavity (4); moreover, the quantitative cavity is communicated with or separated from the outside. In use, a user operates the upper cover to move with respect to the base, and a movable piston (41) moves with respect to the quantitative cavity, so that the liquid outlet control structure separates the quantitative cavity from the outside and the liquid inlet control structure enables the inner cavity of the container body to be communicated with the quantitative cavity; when a needed amount is reached, the user continues to operate the upper cover to move with respect to the base, the liquid outlet control structure enables the quantitative cavity to be communicated with the outside and the liquid inlet control structure separates the inner cavity of the container body from the quantitative cavity, so that liquid in the quantitative cavity can be poured out. The container is reasonable in design, concise in structure, and convenient in use, can implement quantitative pouring, and has low production costs.
