It is well known from the specification. The device acts to dispense the product in an aerosol form and comprises a combination of a high volume dispensing device and a low volume dispensing device, the two dispensing devices being in communication with each other. Can be made A first dispenser having a high volume contains a gas permeable pouch containing the product to be dispensed and a first propelling liquid, but has a small volume and is formed by the space between the pouch and the device container. The second dispenser dispenses the second propellant liquid under a lower pressure than the propellant liquid contained in the pouch. In this known device, the product to be dispensed and a portion of the first propellant to be mixed pass through the wall of the pouch and mix with the second propellant liquid. This means that the pressure in the pouch containing the product to be dispensed will decrease and the pressure in the space surrounding the pouch will increase until it equilibrates. The disadvantage of this device is that the concentration of the propelling liquid in the product to be dispensed decreases during the dispense.

Is in a liquid flow equilibrium capable of maintaining sufficient pressure (about 3 bar) corresponding to the vapor pressure and temperature of the liquid used. The propellant means 14 can be introduced into the part 10 by means of a needle A inserted in the stopper 8. Even if the needle A is pulled out, the sealed state is surely continued by the stopper 8.

The flexible pouch 9 is a membrane that is sufficiently permeable to allow the gaseous propellant means to pass through the membrane so as to balance the pressure of the propellant means between the inner and outer portions 10 of the pouch 9. It is formed by. The membrane of the pouch 9 is, of course, impermeable to the active product 2 which remains trapped inside the pouch 9.

The introduction of the active product into the pouch 9 depends on the distribution valve 1

FIG. 7 and the following figures are diagrams showing the results obtained with the pressure dispenser according to the invention during the tests carried out on foamed products. With some of these diagrams, the results according to the invention can be compared with the results obtained with conventional devices.

FIG. 7 shows the change with time in the flow rate g / sec plotted on the Y-axis of the device of the present invention having a body mousse plotted on the X-axis. The X-axis scale is not a uniform scale.

In the test carried out by the device of the present invention in which the pouch 9 was filled with the body mousse, the valve rod 13 of the distributor valve 11
Was pressed every 5 seconds with a time interval as shown on the X-axis, that is, after the time from point 0 to 1/2 hour, 1 hour, 11 hours, 2 hours, 3 hours, etc.

The product dispensed by the device of the invention is collected and weighed. The flow rate g / sec is obtained by dividing the collected mass by the discharge time.

This flow rate was maintained at about 1.7 g / s even after 78 hours.
It is clear from this diagram that ec is kept at a nearly constant value.

The diagram of FIG. 8 shows the pressure fluctuation bar plotted on the X-axis inside the pouch 9 of the device according to the invention in which the test illustrated by the diagram of FIG. 7 has been carried out.

It is clear that the pressure remains relatively constant. This pressure is about 3.4 bar and is still about 3 bar after 78 hours.

The diagram of FIG. 9 shows that the pouch 9 having a certain degree of transmittance is made of PVC (polyvinyl chloride) according to the present invention (measurement results are plotted in white squares) and the pouch is flexible. Figure 3 shows the results of a comparative test performed with a conventional device made of a permeable material (aluminum foil) and an active product located inside a pouch, respectively. Each measurement point of the conventional device is shown by a black square in FIG.

The flow rate g / sec is plotted on the Y axis. Each measurement point corresponds to spraying for 5 seconds. Sequential spraying operations are spaced at 30 min intervals. The number of spraying or dispensing operations is plotted on the X-axis.

Clearly, the device of the present invention has much less variation than the flow rate of conventional devices.

The flow rate curve of the device according to the invention lies below the conventional curve for the first 5 spraying operations and then above the other curves from the 6th spraying operation. Reduction of flow rate according to the present invention (about 1.
Approximately 1.5 from 8 g / sec to the 10th spraying operation
(up to g / sec), even if the number of spraying operations is increased, in the conventional case (from about 1.9 g / sec for the first spraying operation to about 0.8 g / sec for the tenth spraying operation) Even much less noticeable.

FIG. 10 compares the device of the present invention used in the test of FIG. 9 with the conventional device and plots the expansion of the pressure bar plotted on the Y-axis in the volume containing the active product with respect to the number of dispensing operations. It is a comparison diagram shown.

In this case too, the diagram of the device according to the invention, corresponding to each point represented by the white square, is represented by the black rectangle of the conventional device (between about 4.6 bar and about 3 bar). It is clear that it is closer to constant (variation limited between 4 bar and about 3.4 bar) rather than (variation).

The diagram of FIG. 11 shows a comparative test of another method carried out on the device of the present invention (measurement points are represented by white squares) and the conventional device (black squares).

In these tests the volume containing the active product (which gives rise to foaming) is not filled with propellant means at the time of manufacture. That is, in the case of the device according to the invention in which the active product is placed in the pouch 9, the propellant means is not injected into the pouch 9. Prior art devices that place the active product inside a flexible pouch do not inject propellant means into the pouch.

The measurement whose results are shown in FIG. 11 was carried out for one week after the manufacture of this device. That is, the device was stored unused for one week in question.

The concentration measurement was carried out twice in each test, ie once at the beginning of the dispensing and once again after the foam was expanded, ie 5 minutes after the foam had been delivered.

After one week of storage, the concentration of product dispensed by conventional equipment remains constant according to the emptying rate of the equipment. Furthermore, this concentration corresponds to the concentration of the active product which is relatively high and does not swell.

According to the invention, foamed foams are obtained without introducing propellant means into the volume containing the active product.
In addition, the concentration remains almost constant during the empty period.

The device of the present invention has a capacity of 10 after storage for one week.
The propellant gas of is sufficiently diffused toward the pouch 9 containing the active product.

On the other hand, in conventional devices, the flexible pouch is impermeable so that the propellant means contained within the pouch cannot diffuse into the active product.
