This device for applying a deodorant comprises a chamber (1) which is a transparent bottle, which contains a saturated alum solution (2) and alum crystals (3). The device is equipped with a conventional hand pump (4) provided with a push-button (5) to allow the solution to be extracted and sprayed onto the body. The bottom of the pump has an inlet (6) via which the solution is drawn up when the pump is operated. A cylindrical second chamber (8) is fixed around the bottom of the pump via its upper end (9). The lower end (12) of the second chamber extends down to the bottom (10) of the bottle, but leaving a gap to allow the solution drawn up by the pump to pass through the passage (11) left open. The interior volume (13) of the second chamber (8) is at least three times greater than the volume of the solution that the pump can extract in a single press of the push-button. Each time the push-button is pressed, the pump therefore extracts only the top portion contained in the second chamber, which means that the small crystals, which are not carried up as high as this, do not block the pump. The volume of solution contained in the second chamber allows several applications in the inverted position.

1. Device for applying an alum solution comprising at least a first chamber (1) containing a saturated alum solution (2) and alum crystals (3); a pump (4) capable of being operated by at least one push-button (5) and enabling the emission of a portion of the solution towards a part of a body, the pump (4) having at least one inlet (6) linking the pump (4) to the first chamber (1); at least one second chamber (8) into which the upper part (9) of said inlet (6) opens directly or through at least one conduit (7) having at least one suction point (16), said second chamber extending towards the bottom (10) of said first chamber; at least one passage (11) being arranged in the lower part (12) of said second chamber such as to make the interior volume (13) of said second chamber communicate with said first chamber, such that the saturated alum solution and the alum crystals at least partially fill said second chamber; said upper part (9) being fixed, so as to be sealed, directly or indirectly at the top of the first chamber or to the pump, such as to prevent any transfer of said alum solution between said chambers by any other way than said passage (11), wherein the interior volume (13) of the second chamber (8) between the inlet (6) and the highest point of the passage (11) represents at least three times the volume of the alum solution that the pump (4) can extract during a single stroke of the push-button. 2. Device according to claim 1, wherein the second chamber is in the form of a hollow cylinder, said passage being formed by a lower aperture of said cylinder. 3. Device according to claim 1, including a filter (14) fixed in front of the suction point (16). 4. Device according to claim 2, wherein the distance between the bottom of the second chamber and the bottom (10) of the first chamber is less than the internal diameter of said cylinder. 5. Device according to claim 1, wherein the second chamber is transparent. 6. Device according to claim 3, wherein the filter (14) is disposed in the upper part (9) of the second chamber. 7. Device according to claim 1, wherein the distance between the bottom of the second chamber and the bottom (10) of the first chamber is less than the internal diameter of said cylinder.
