- a container;
- a container cap including a membrane seal;
- and
- a liquid dispenser adapted to be connected to the container cap, wherein the liquid dispenser comprises a spout having a liquid channel within said dispenser, said spout being pivotably movable between two positions to position the dispenser in either an unopened or open configuration, wherein
- the container cap is attached to the container to allow the membrane seal to cover an outlet of the container;
- an end of the liquid channel is movably advanced into the outlet of the container in the open configuration and is withdrawn outside the outlet in the unopened configuration;
