    EXTRACT
    The invention relates to a device for administering an amount of liquid coolant, comprising: - a container for containing the liquid coolant; - a normally closed valve connected to the container; operating means for temporarily opening the valve, comprising positioning means for positioning at least a part of the administration element so that the coolant emerging from the valve can reach the administration element.
    By means of this measure, the majority of the refrigerant exiting the valve enters that part of the administering element which comes into contact with the wart for effective use.
    According to a first preferred embodiment, the positioning means comprise a chamber connected to the valve, into which, when the valve is actuated, the coolant is introduced, which chamber is arranged for placing at least a part of the administering element.
    DEVICE FOR DELIVERING A QUANTITY OF LIQUID REFRIGERANT AND A DELIVERY ELEMENT
    The present invention relates to a device for administering an amount of liquid coolant, comprising: - a container for containing the liquid coolant; - a normally closed valve connected to the container; and - operating means for temporarily opening the valve.
    Such a device is known from patent publication EP-B-0 608 954.
    This known device uses a thin pipe which is connected to the valve and which is provided with a foamed, porous body at its free end. The pipe opens into the interior of the foamed body.
    Such a device is used, for example, for removing warts. Hereby an amount of coolant, which has been applied to the administration element, is pressed onto the wart, after which it cools and disappears. This method is generally known per se; it is performed by general practitioners using liquid nitrogen.
    When using this known device, the valve is pressed in and coolant enters through the valve and the nozzle into the interior of the foamed body. The coolant must then flow outward inside the foamed body in liquid or gaseous form. This leads to a decrease in effectiveness; after all, the coolant must spread within the foamed body, so that only part of the coolant reaches the place where the foamed body comes into contact with the wart.
    The object of the present invention is to provide such a device in which the above drawbacks are avoided.
    This object is achieved by positioning means for positioning at least part of the administering element so that the coolant exiting the valve can reach the administering element.
    By means of this measure, the majority of the refrigerant exiting the valve enters that part of the administering element which comes into contact with the wart for effective use.
    According to a first preferred embodiment, the positioning means comprise a chamber connected to the valve, into which, when the valve is actuated, the coolant is introduced, which chamber is arranged for placing at least a part of the administering element.
    It will be clear that a particularly effective administration is obtained by this embodiment; after all, the coolant is given the opportunity to spread within the room, and it can only escape with difficulty.
    An even more attractive embodiment is obtained when the actuating means are only coupled to the valve when the administering element is placed in the cavity. This measure has the result that the actuating means are only effective when an administering element is placed in the cavity. This means that the valve cannot be operated without an administering element, so that it is prevented, for example, that children spray the coolant with the associated dangers. Another advantage is that this administration element can only be wetted with the coolant if the administration element is correctly positioned. This also improves effectiveness.
    Other attractive preferred embodiments are evident from the other sub-claims.
    The present invention will be elucidated hereinbelow with reference to the annexed drawings, in which: figure 1 shows a side view of a device according to the present invention, wherein a part of the device is shown as a cross-section, in the situation of the insertion of the administering element; figure 2 is a view corresponding with figure 1 in which the administering element is placed in the chamber; and figure 3: a view corresponding with figures 1 and 2 during operation of the valve.
    Figure 1 shows an aerosol container 1, which is closed at its top in the usual manner with a lid 2, which is seamed in the form of a beaded edge 3 around the top edge of the aerosol container 1. A valve 4 is provided in the lid, which, when pressed on its top, connects the interior of the aerosol container with the environment with a small opening in its top.
    Such an aerosol container is generally known. At the top of the aerosol container 1, a cap marked 5 in its entirety is placed. This cap engages underneath the beaded edge 3 by means of an internal ring 6 arranged for this purpose. The cap is substantially cylindrical, and is provided with a spout 10 on one side. The top of the cap 5 is provided with a conical rounding 6, and a pressure surface 8 is arranged in the center of the top of the cap 5. The pressure surface 8 is connected to the other part of the cap 5 by means of an annular, thinned section ν '-shaped, as a result of the thin part 9, it is possible to press the cap 8 downwards. The thinned part 9 acts as a kind of hinge.
    The spout 10 is annular and has a groove 11 on its inner side. The part of the cap described so far is manufactured in one piece from a suitable plastic by means of, for example, injection molding or another shaping technique.
    In the interior of the spout 10, an accessory indicated in its entirety by 12 is placed. The fitting 12 is initially formed by a cylindrical part 13, which fits snugly within the spout 10, and which is provided with an edge 14, which fits into the groove 11. This provides fixation of the cylinder 13, and thus of the entire attachment 12.
    However, it is also possible that the fitting, together with the cap as a single injection molded part. is manufactured.
    The accessory 12 further comprises a coupling piece 15, which is connected to the cylinder 13 by means of an elastic strip 16. The coupling piece 15 is formed by a cylindrical part 17, which is provided at its top with a chamfer surface 18, and in which a channel 19 is arranged. Furthermore, a conical spout 20 is arranged at the bottom. At its top side, the coupling piece 15 comprises a hemispherical part 21, which fits into a correspondingly shaped engaging part 22, which is formed on the underside of the pressure surface 8.
    The length and thickness of the connecting strip 16 are such that in the normal state the coupling piece 15 occupies the position shown in figure 1. On the other hand, when an administering element is pushed into the cylinder 13, the strip 16 is stretched, because the administering element presses against the underside of the cylindrical part 17. Then the situation shown in Figure 2 is obtained.
    The administering element, shown in its entirety at 25, because essentially a rod-shaped support 26 made of plastic, to which a handle 27 is attached. Hooks 27 are mounted on the free end of the rod-shaped support 26, onto which an absorption element 28 made of a plastic foam is pushed against a wall 30.
    Although the present invention is particularly dimensioned for the use of a plastic foam, it is of course possible to use other materials, such as, for example, rolled-up cotton wool, other cellulose products, sponge-like structures, etc.
    Instead of a plastic carrier 26, which is provided with a handle, it is of course also possible to use other carriers, such as, for example, wooden sticks, etc.
    Next, the operation of the present invention will be explained. In the situation shown in figure 1, the administering element 25 is not yet. placed in the space formed for that purpose. The coupling element 15 is therefore in the position shown in figure 1, so that it cannot become a coupling between the pressure surface 8 and the valve 4. When the pressure surface 8 is pressed in the drawn condition, the valve 4 is therefore not actuated, so that the coolant is not wasted or dangerous situations are created.
    When subsequently the administering element 25 is pushed into the cylinder 13, and is pushed further, until the foam 29 presses the cylinder 17 and pushes it so far that the cylinder 17 extends in line with the valve 4, the situation is obtained shown in figure 2.
    It is otherwise possible to temporarily fix the administering element in the cylinder by means of a snap connection.
    The foam 29 is then located in the positioning chamber formed by the cylinder 13. When the pressure surface 8 is pressed in the situation shown, a coupling is created between the pressure surface 8 and the valve 4, so that the cooling liquid from the valve 4 can flow, and the situation shown in Figure 3 is obtained.
    The coolant then flows through the channel 19 and enters the application space, where the foam 29 will enter and distribute over the foam. Hereby an almost complete absorption of the coolant takes place in the foam 29, so that the foam 29 is, as it were, soaked with coolant.
    When the delivery element is subsequently moved out of the chamber 13, and the foam 29 is released into the free space, the coolant will evaporate, causing cooling, and when the foam then falls on a wart, it will freeze, after which it will cool down. time disappears.
    It would be possible to press the operating element for a long time, as a result of which the administration element would become supersaturated with coolant and could drip when removed.
    This is prevented because the cap construction also freezes when the operating element is pressed for too long and the coupling between operating element and valve is broken.
    It will be clear that the present preferred embodiment can be deviated from in various ways without departing from the invention.
