Assembly and method for introducing a dose of a mixing substance into a container
First Claim
1. An assembly for introducing a dose of a mixing substance into a container, said assembly comprising a dosing part and a supply part, which dosing part is arranged for receiving the dose and which supply part comprises a chamber wall and an outlet for introducing the dose into the container,wherein the dosing part and the supply part are configured to cooperate with one another, such that a pressure chamber having a changeable volume is formed adjacent to the outlet when the supply part and the dosing part are joined together, and wherein the dosing part is adapted to move toward and away from the supply part to decrease and increase the volume of the pressure chamber for enabling a pumping action for pumping the dose into and out of the pressure chamber;
- wherein said chamber wall of said supply part blends into said outlet and the chamber wall and the outlet comprise smooth inner sides and rounded corners for reducing a risk of residue of said dose remaining in said supply part,wherein the dosing part comprises a sealing element corresponding to the outlet and in detachable engagement with an inner wall of the outlet, the sealing element is configured to seal the outlet, and the detachable engagement of the sealing element and the inner wall of the outlet enables said pumping action for pumping the dose into and out of the pressure chamber, andwherein the sealing element in the dosing part is disposed outside a dose container portion of the dosing part.
