The lid 4 is mounted on the lower end of the tank 2 by known methods of clipping, the lid 4 being provided in the present example with a circular cavity c, which has a diameter equivalent to the outer diameter at the base of the tank 2.

The utility function of the tank stopper, according to the invention, is given by the following successive steps, some of which can be modified in order:

- closing the lid 4 by clipping the lower body of the tank 2;

- Filling the tank 2 with the substance 6 to be mixed;

- Placing in a vertical position the tank 2 inside the neck of the container 3 up to the level of the collar of the elastic of the tank 2;

- Threaded mounting of plug 1 until the collar a is clipped inside the recess d provided inside the plug 1;

- Opening the stopper 1 with the extraction of the tank 2, at which point the opening / closing lever 8 opens forcibly when it touches the narrow side of the container 3;

- The gravitational evacuation of the substance 6 to be mixed takes place in the liquid 7 from the container 3, the step that can be followed, if necessary, to shake the container in order to homogenize the mixture.

For example, we can fill the tank 2 with soluble granular coffee with sweetener, and the liquid in the container 3 can be water.

There is the possibility of using substances 6 of mixture that by combining with the liquid 7 to generate various dynamic aesthetic effects in the dissolution process.
