Definitions

• the present invention relates to the field of devices intended to apply saturated solutions of alum, on the skin, essentially as deodorants, these solutions may of course contain other ingredients, such as alcohol, preservatives, or any other agent, for example antiperspirants.
• the solution being saturated it necessarily contains undissolved alum crystals.
• the ammonium alum crystals have a density of 1.65
• the potassium alum crystals have a density of 1.73, the difference is minimal, and the invention therefore applies to any type of saturated solution. 'alum.
• Devices composed of a vial, preferably transparent, containing a saturated solution of alum, in which are bathed undissolved alum crystals, and which are provided with a manual pusher pump for projecting spray jets from the solution to the part of the body that the user aims at.
• a manual pusher pump for projecting spray jets from the solution to the part of the body that the user aims at.
• said pump is removably attached to the top of the bottle, usually by a thread.
• the solvent of the solution is preferably water.
• Still other documents propose to include in the bottle a second sealed chamber and more or less flexible containing the solution to be dispensed, which deforms as the liquid it contains is pumped.
• This is the case for example US 3,089,624 Micallef, US 3,257,036 Micallef and US 4,322,020 Stone.
• the lack of these solutions lies in particular in the need to introduce and fix in the bottle a second chamber, which seems rather complex.
• the present invention aims to provide an apparatus that avoids the aforementioned drawbacks, that is to say an apparatus that allows to extract almost all the alum solution while minimizing the risk of blockage of the pump by crystals , as well as a use of the bottle in all positions, even completely reversed.
• the apparatus for applying an alum solution according to the invention comprising at least a first chamber capable of containing a saturated solution of alum and alum crystals.
• a pump that can be actuated by at least one pusher and making it possible to emit part of the solution to a part of the body, the pump having at least one inlet connecting the pump to the first chamber, is characterized in that it comprises at least one second chamber in the upper part of which said inlet opens directly or via at least one duct provided with at least one suction point, said second chamber extending towards the bottom of said first chamber, at least one passage being arranged in the lower portion of said second chamber so as to communicate the interior volume of said second chamber with said first chamber, said upper portion being attached directly or indirectly in a sealed manner to the top of the first chamber or to the pump, so as to to prevent any transfer of said alum solution between said chambers by a route other than said passage.
• the apparatus according to the invention is characterized in that the interior volume of the second chamber between the inlet and the highest point of the passage represents at least three times the volume of alum solution that the pump can extract during a single stroke of the pusher.
• the apparatus according to the invention is characterized in that the second chamber has the shape of a hollow cylinder, the passage being constituted by the lower opening of said cylinder.
• the apparatus according to the invention is characterized in that a filter is fixed before the suction point.
• the apparatus according to the invention is characterized in that the distance between the bottom of the second chamber and the bottom of the the first chamber is smaller than the inner diameter of said cylinder.
• the apparatus according to the invention is characterized in that the chambers contain a saturated solution of alum and crystals of 'alum.
• the apparatus according to the invention is characterized in that the second chamber is transparent.
• the apparatus according to the invention is characterized in that the filter is placed in the upper part of the second chamber.
• Figure 1 is a vertical section of an apparatus in a first embodiment of the invention, in a vertical position, the pump being at the top.
• Figure 2 is an enlarged view of the lower part of the pump shown in Figure 1, with the second chamber surrounding it according to the invention.
• FIG. 3 is a section like that of FIG. 1, but in which the apparatus is in an inclined position, the pump being at the bottom, and at the inlet of which a filter has been added, in order to avoid the intrusion of mini-crystals in the pump.
• the apparatus comprises at least a first chamber 1, whose walls are preferably transparent, that is to say practically made of plastic material or glass, and which is provided with a threaded neck on which is screwed a manual pump 4.
• This pump 4 shown schematically, and in particular without the springs, is of a current model. It is actuated by a pusher 5.
• the first chamber 1 is filled with a saturated solution of alum 2.
• the solvent is preferably water.
• alum crystals 3 which ensure a constant saturation of the solution, even after several additions of water in the chamber, until their complete dissolution.
• the filling of the bottle is done by the neck, after unscrewing the pump. This is manually operated by the pusher 5.
• the details of the pump are not shown here.
• the inlet of the pump 6, under the ball which operates as a valve, however, is visible in particular in Figure 2.
• the inlet 6 of the pump is extended by a conduit 7 which moves the suction point 16 at the end of this conduit.
• This conduit has a diameter corresponding substantially to that of the valve ball.
• a suction tube 15 is placed in the bore of the conduit 7, and extends to the bottom of the bottle, as is the case in document PCT / CH8900104 Verdan. As we have seen, when there are solids in the solution, these fine ducts forcefully suck the mini-crystals present in the solution. The conduit drives the mini-crystals into the pump, preventing it from operating properly.
• the apparatus comprises at least a second chamber 8, which here has the shape of a cylindrical pipe, but which could have other shapes.
• the second chamber surrounds by its upper end 9 the bottom of the pump 4. There is no gap between this upper end 9 and the bottom of the pump, so that the fixing between the bottom of the pump and the upper end 9 is sealed and prevents any passage of the alum solution from the top of the second chamber 8.
• the second chamber 8 extends to the bottom 10 of the first chamber 1.
• a passage 11 however opens to pass the solution through the lower end 12. In this case, the passage 11 is simply constituted by the lower opening of said second chamber.
• the solution can pass inside 13 of the second chamber 8 through this passage 11 because of the distance, preferably quite small, which is formed between the lower end 12 of the second chamber and the bottom 10 of the first chamber .
• the volume of the second chamber It is necessary and essential for the volume of the second chamber to be large enough and to size it so that the volume of alum solution 2 extracted during a single full thrust of the pusher 5 is no more than a relatively small fraction of the volume contained in the second chamber 8.
• a single push of the pusher carries all the contents of the tube, and even more. It follows a very fast current, which drives the small crystals towards the entrance of the pump and the valve, and tends to clog them.
• a thrust of the pusher causes only a portion of the solution which is located at the top of the the second bedroom. A current occurs of course, but it is almost zero and much less strong than the current produced in the known devices.
• the small crystals are almost not entrained in the second chamber 8 and they do not rise substantially towards the pump, which eliminates the risk of crystals being present around the suction point 16.
• the crystals remain at the bottom of the bottle and never come into contact with the suction point 16 of the pump.
• the liquid will remain in the second chamber up to the height of the suction point 16 even if the liquid level is lower than said suction point in the first chamber. This is because the second chamber 8 is sealed at its uppermost point, thereby preventing the liquid in the pump from escaping, the air not being able to enter to replace the liquid.
• the second chamber 8 will thus remain full until complete use of the liquid contained in the first chamber.
• the amount of alum solution 2 that is inside the second chamber is sufficient to provide multiple applications in the inverted position where the pump is down.
• the internal volume 13 of the second chamber 8 represents at least three times the volume of alum solution that the pump can extract during a single stroke of the pusher 5, that is to say during operation of pushing the pusher 5 from its highest point to its lowest point, without reverse movement, that is to say again without the user lifts the finger during the operation.
• This allows the user, for example, to easily use the apparatus for application on the feet which generally requires an inverted position of the bottle.
• the invention which can be easily produced with known means, can be used in the cosmetics industry and is used for the application of an alum solution as a deodorant.
