BACKGROUND OF THE INVENTION Propellant means are capable of maintaining liquid flow equilibrium within a suitable temperature range to obtain a desired pressure.

[0003] This type of apparatus is disclosed in FR 2,281,290.
It is well known from the specification. The device acts to dispense the product in aerosol form and comprises a combination of a high volume dispenser and a low volume dispenser, the two dispensers being in communication with each other. Can be done. A first dispensing device having a high volume contains a gas permeable pouch containing the product to be dispensed and a first propellant liquid, but has a small volume and is formed by the space between the pouch and the device container. The second dispenser charges the second propellant liquid at 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 pouch wall and mix with the second propellant liquid. This means that the pressure in the pouch containing the product to be dispensed decreases and the pressure in the space surrounding the pouch increases until equilibrium is reached. A disadvantage of this device is that the concentration of the propellant liquid in the product to be dispensed drops during dispensing.

FIG. 7 and the following figures are diagrams showing the results obtained with a pressure dispenser according to the invention during tests performed on foamed products. Some of these diagrams allow the performance according to the invention to be compared with the performance obtained with conventional devices.

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

In a test performed by the apparatus according to the present invention in which the bag 9 was filled with the body mousse, the valve rod 13 of the distribution valve 11 was used.
Was pressed every 5 seconds at time intervals as shown on the X-axis, that is, after 1/2 hour, 1 hour, 11/2 hours, 2 hours, 3 hours, etc. from point 0.

The products dispensed by the device according to the invention are collected and weighed. The flow rate g / sec is obtained by dividing the collected mass by the release time.

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

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, which was tested according to the diagram of FIG.

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 in FIG. 9 shows that the sachet 9 having a certain transmittance is made of PVC (polyvinyl chloride) (the measurement results are plotted as white squares), and the sachet 9 is flexible. The results of comparative tests performed with a conventional device made of a permeable material (aluminum foil) with the active product positioned inside the pouch, respectively. Each measurement point of the conventional device is indicated 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. The successive spraying operations are spaced at intervals of 30 min. The number of spraying or dispensing operations is plotted on the X-axis.

It is clear that the apparatus of the present invention has much less variation than the flow rates of conventional apparatuses.

The flow rate curve of the device of the present invention lies below the conventional curve for the first five spray operations and then above the other curves from the sixth spray operation. Reduction of flow rate according to the invention (about 1. 1.
8 g / sec to about 1.5 for the tenth spraying operation
g / sec), even if the number of spraying operations is increased, compared to 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). Nor much noticeable.

FIG. 10 shows that the apparatus of the present invention used in the test of FIG. 9 is compared with the conventional apparatus, and the Y-axis in the volume containing the active product shows the development of the pressure bar plotted against the number of dispensing operations. FIG.

Also in this case, the diagram of the device of the present invention corresponding to each point represented by a white square is a diagram of a conventional device represented by a black square (between about 4.6 bar and about 3 bar). It is evident that it is even closer to constantity (fluctuation limited to between 4 bar and about 3.4 bar).

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

In these tests, the volume containing the active product (causing foaming) does not fill the propellant means during manufacture. That is, in the case of the device of the present invention in which the active product is put in the sachet 9, the propellant means is not injected into the sachet 9. Conventional devices for placing the active product inside a flexible sachet do not inject propellant means into the sachet.

The measurement shown in FIG. 11 was performed for one week after the production of this device. That is, the device was stored unused for the week in question.

The measurement of the concentration was carried out twice in each test, once at the start of the dispensing and once again after the expansion of the foam, ie 5 min after delivery of the foam.

The concentration of the product dispensed by the conventional device after one week of storage remains constant according to the rate at which the device is emptied. Furthermore, this concentration corresponds to the concentration of the active product which does not swell relatively high.

According to the invention, a foamed foam is obtained without introducing propellant means into the volume containing the active product.
Furthermore, the concentration remains almost constant during the course of the process.

In the device of the present invention, after storing for one week,
Of the propellant gas diffuses sufficiently toward the pouch 9 containing the active product.

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