- FIG. 4A the flap slide 101 is in the low position so that the air intake opening 100 is cleared.
- the volume of composition C1 distributed is replaced by a corresponding volume of air so that the equilibrium pressures are maintained.
- the distributed composition C1 is of concentration fixed.
- the level of product gradually decreases in the container 11, and remains unchanged in container 12.
- the sliding shutter 101 is moved so as to occupy the high position. This position is shown in Figure 4B. In this position, the air intake orifice 100 is closed.
- each volume of composition C1 distributed by the pump 5 from the first container 11 is replaced by a corresponding volume of composition C2. It is then produces, as a function of the relative concentrations of compositions C1 and C2, a dilution or concentration effect of the composition distributed by the pump 5. Indeed, in this phase, the volume of composition C1 in the first container remains constant. This dilution or concentration effect is gradually in response to each pumping by means of pump 5.
- the entire composition booster C2 has been transferred to the first container 11, so that the liquid composition C1 contained in the first container 11 is of concentration at most equal to the concentration of the make-up composition C2 in the second container.
- the ratio of the volumes of the first and second containers is a factor determinant for the value of the final concentration of composition C1 in the first container. From this moment, at each pumping, the volume contained in the first container 11 decreases by an amount equal to the volume of the dose dispensed, until the first container 11 is completely emptied. last phase, the concentration of composition C1 is constant. The length of this last phase is inversely proportional to the length of the phase during which pumping from the first container 11 is carried out with air intake.
- the particular distribution process which has just been illustrated comprises three main phases: a first phase, in the lower position of the sliding shutter 101 and in which only composition C1 is distributed at a fixed concentration; a second phase, in the upper position of the flap 101, and in which is distributed a mixture of compositions C1 and C2, according to an increasing concentration or gradually decreasing; and a third phase in which the composition distributed is at constant concentration, which concentration is at most equal at the concentration of the make-up composition C2 initially present in the second container.
- any other succession of sequences is possible, depending in particular on the type of application or the circumstances. So, it is possible to distribute the entire content of the device with the shutter sliding 101 in the high position, that is to say in the closed position of the orifice air intake 100. In this case, the concentration curve of the composition distributed will present a short stage with fixed concentration (corresponding to the priming phase of the siphon), a portion with progressive concentration or decreasing, and a final level with fixed concentration. Alternatively, in response to a change in the circumstances surrounding the application of the composition, it is possible to move the sliding shutter from the high position to the low position during the variable concentration distribution phase, so as to create a to compensate for concentration between two phases with variable concentration, etc.
- each phase and in particular, the slope of the curve in the phase (s) with variable concentration, is adjusted as desired by appropriately choosing the main parameters of the device, that are in particular, the respective volumes of each container, the concentrations initials of each of compositions C1 and C2, the volume of the pumped dose, and the configuration of the siphon.
