Therefore, the contents of the tank 2 can mix with the contents of the container by passing through neck 13. If the substance in tank 2 is a product self-gasifying in contact with water, the pressure produced by this release of gas produces the separation of the part 8 of the cover, leaving free the opening of the neck 13. In any case, the diameter of this cover being greater- at the inside diameter of the neck 13, there is no risk that it falls inside this neck.
• connection of the reservoir 2 with the container, of which the neck 13 can be seen takes place automatically by breaking the cover, simply by adapting the reservoir cap 1 on the neck 13 of this container.

You can reuse the same container (a bottle for example) as often as you want, by simply filling it with water and screwing a new cap.
• the device described makes it possible to reduce in a very large proportion, practically by at least 90%, the weight and the volumes that the user must currently transport from the place of purchase to his home for the same quantity of lemonade desired, and be delivered in the same proportions for the elimination of waste from the packaging of the products used.
• the device described is not limited to the production of lemonade or other drinks, but that it can be used in the food or pharmaceutical fields to mix, in water or in a preparation, liquid or solid extracts which must be stored away from air to avoid oxidizing.
• This device can also be used for the preparation, by mixing, of paints or household cleaning products requiring that the mixing be done just before use.
• the closure of the reservoir 2 by a cover such as 7 ensures not only the sealed closure of this tank, but also its inviolability without destruction of the cover, thus avoiding any possibility of introducing a foreign product into the tank 2 by malice. without this being immediately visible due to damage to the cover.

• Projections 26 are integral with the face of the groove 24 facing towards the inside of this groove. These projections are arranged to cooperate with the ramps 20 and the notches 21, when these two elements 1 and 18 are assembled. By rotating these elements 1 and 18 relative to one another, when the projections 26 are in contact with the ramps 20, these projections are forced to move along the helical ramp, until they arrive opposite the recesses or notches 21, where they fall and thus prevent the separation of the elements 1 and 18 , while ensuring the compression of the seal 25.
