The positioning device positions at least a part of an administering element so that the cooling agent leaving the valve can reach the administering element. The cooling agent leaving the valve reaches that part of the administering element which comes into contact with a wart to be frozen, so that it is used effectively. According to a first preferred embodiment the positioning device has a chamber which is connects to the valve and into which the cooling agent is carried when the valve is operated. The chamber is adapted to receive of at least a part of the administering element. ## Claims ### Claim 1 A device for administering a quantity of liquid cooling agent, comprising: an aerosol container for holding the liquid cooling agent; a normally closed Valve connected to the container; operating means for temporarily opening the valve; and an administering element, comprising an absorption element and a carrier, the administering element being separable from the rest of the device, characterized in that the device comprises positioning means for positioning at least a part of the absorption element in a position wherein cooling age,it leaving the valve can directly reach the absorption element. ### Claim 2 (depends on 1) A device as claimed in claim 1, characterized in that the positioning means comprise a chamber which is connected to the valve and into which the cooling agent is carried when the valve is operated, which chamber is adapted for placing of at least a part of the absorption element. ### Claim 3 (depends on 2) A device as claimed in claim 2, characterized in that the operating means are adapted to be coupled to the valve only when the absorption element is placed in the chamber. ### Claim 4 (depends on 3) A device as claimed in claim 3, characterized in that the operating means comprise a movable element, a displaceable coupling piece is movable between a first position, in which the coupling piece couples the operating means to the valve, and a second position in which this is not the case, that the coupling piece is normally situated in the second position and the coupling piece is only caused to move to the first position by placing the absorption element in the positioning means. ### Claim 5 (depends on 4) A device as claimed in claim 4, characterized in that the coupling piece is connected by a resilient element to the container and that the resilient element is adapted to urge the coupling piece to the second position. ### Claim 6 (depends on 5) A device as claimed in claim 5, characterized in that the resilient element, the coupling piece and the positioning means are formed integrally. ### Claim 7 (depends on 6) A device as claimed in claim 6, characterized in that the resilient element, the coupling piece and the positioning means are placed clampingly in an otherwise integrally manufactured cap unit with the operating means integrated therein which is fixable on the container by means of a snap connection. ### Claim 8 (depends on 5) A device as claimed in claim 5, characterized in that the resilient element is adapted to at least partially transfer the force of the absorption element to the coupling piece. ### Claim 9 (depends on 4) A device as claimed in claim 4, characterized in that the coupling piece is always coupled to the operating means. ### Claim 10 (depends on 9) A device as claimed in claim 9, characterized in that the coupling piece is provided on its side directed toward the operating means with a hemispherical part. ### Claim 11 (depends on 4) A device as claimed in claim 4, characterized in that the coupling piece is provided with a channel for guiding the liquid cooling agent from the valve to the absorption element positioned by the positioning means. ### Claim 12 (depends on 11) A device as claimed in claim 11, characterized in that the channel is connected to the outlet opening of the valve only in the first position of the coupling piece. ### Claim 13 (depends on 3) A device as claimed in claim 3, characterized in that the coupling between the operating means and the valve is broken when the absorption element arranged in the container is frozen. ### Claim 14 (depends on 2) A device as claimed in claim 2, characterized in that the operating means are integrated into the chamber and that the operating means are activated when the absorption element is placed in the chamber. ### Claim 15 (depends on 14) A device as claimed in claim 14, characterized in that the chamber is placed with its axis directly inline with the valve and the direction of movement of the absorption element to be moved into the chamber corresponds with the operating direction of the valve. ### Claim 16 (depends on 15) A device as claimed in claim 15, characterized in that the charter is cylindrical and is provided on its inside with a shoulder. ### Claim 17 (depends on 16) A device as claimed in claim 16, characterized in that the chaser is connected by a yielding element to a cap placed on the container. ### Claim 18 (depends on 14) A device as claimed claim 14, characterized in that the device is provided with a childproof safety device. ### Claim 19 (depends on 18) A device as claimed in claim 18, characterized in that the childproof safety device comprises a cover fixable onto the cap by means of a childproof lock. ### Claim 20 (depends on 18) A device as claimed in claim 18, characterized in that the childproof safety device comprises an element normally preventing depressing of the valve and enabling depressing of the valve from outside counter to spring pressure. ### Claim 21 (depends on 14) A device as claimed in claim 14, characterized in that at least a part of the absorption element fits into the chamber. ### Claim 22 (depends on 21) A device as claimed in claim 21, characterized in that the absorption element is fixable in the chamber by means of a snap connection. ### Claim 23 (depends on 1) A device as claimed in claim 1 wherein at least a part of the administering element can be positioned by the positioning means. ### Claim 24 (depends on 1) A device as claimed in claim 1 wherein the administering element is adapted for at least partial positioning by tile positioning means and comprises: a carrier; a handle connected to the carrier; the absorption element being connected to the carrier, wherein at least a part of the absorption element is adapted to be positioned by the positioning means, characterized in that the absorption element is releasably connected to the carrier. ### Claim 25 (depends on 24) A device element as claimed in claim 24, characterized in that the carrier comprises a mandrel which is adapted to be pressed into the absorption element. ### Claim 26 (depends on 24) A device as claimed in claim 24, characterized in that the carrier comprises a plate which is adapted to close a gap between the carrier and the absorption element. ### Claim 27 (depends on 24) A device as claimed in claim 24, characterized in that the absorption element is manufactured from foam plastic with a semi-open structure. ### Claim
