Patent ID: 11365998

Abstract:
The dosing device is intended for a neck for pouring defined amounts from a container or hose. It consists of a spout attachment that can be screwed or pushed onto the neck, and that optionally can be closed by a separate lid and has a dosing control chamber (14) with variable volume. As a characterizing feature, this chamber fills up from empty when pouring. Said chamber is formed by the space between a control chamber limiter and the interior of a dosing piston (10) and is filled with liquid when pouring a dose, while liquid at (D1) flows down past the dosing piston (10) to the spout (3). Finally, the downwardly displaced dosing piston (10) closes the spout (3) when the control chamber (14) is full. The dose quantities to be poured are adjustable in that the path of the dosing piston (10) can be limited on its side facing the container or hose. The control chamber limiter is variably displaceable axially with respect to the dosing device into the equipped neck and can be held fixedly in any position.
