DESCRIPTION:
BRIEF SUMMARY
THIS INVENTION relates to a device adapted to expel into a room or to supply to a surface exposed within a room, a product, such as an air freshener or deodorant, insecticide or the like, in the form of a gas, vapour, vaporisable liquid or a spray.
Devices of this character are already known, but suffer from the disadvantage that they operate continuously or at intervals independent of the extent to which the room is used so that if a room is little used the amount of product supplied to the room is greatly in excess of what is required, whilst if the device is adapted to dispense the product at a rate appropriate to a room in average use, the amount of product dispensed in a given time may be inadequate for a room which is much used and into and from which people are continually passing. It is an object of the invention to provide a device of the kind specified which overcomes this disadvantage.
According to the invention there is provided a device adapted to be secured to a door to a room, or to a wall, floor or ceiling of a room adjacent a door, and arranged to expel into the room or to apply to a surface exposed within said room, a product in the form of a gas, vapour, vaporisable liquid or a spray, such as an air freshener or deodorant, insecticide, or the like, when the door is opened or closed.
Where the device is adapted to be secured to a door, the device preferably incorporates a roller arranged, when the device is appropriately secured to such door and the door is opened or closed, to run along a floor, ceiling, door frame or wall surface, the expulsion of said product being caused or permitted by such rotation.
In one embodiment, the device includes a bracket adapted to be clipped to a door edge, or otherwise to be secured to a door, adjacent the floor, an arm pivotally connected with the bracket carrying said roller at a free end thereof, with the arm being spring biassed relative to the bracket so that when the bracket is appropriately secured to a door, the arm is pulled into a position in which the roller bears upon the floor surface whereby when the door is open and closed, the roller is caused to run over the floor surface and is thereby caused to rotate.
In one embodiment, the roller may be of sponge rubber or plastics or other absorbent medium, and the product to be dispensed may be in the form of a gel or a wax-like medium impregnating the roller so that when the roller is rolled over the adjacent (e.g. floor) surface a controlled amount of the product will be delivered by the roller onto said surface.
In another arrangement, the arm may, for example, carry a reservoir of liquid to be dispensed, closed at its lower end by a permeable pad bearing upon the roller surface on the upper side of the roller, so that when the roller rolls over the floor, the roller is coated with the liquid and in turn applies such liquid to the floor surface to evaporate from the latter.
Alternatively, the product may comprise a block or stick of a wax or soap-like material incorporating the material to be dispensed in a similar manner. In this case, the roller may have a rough or absorbent surface, for example provided by foam plastics or the like whereby the roller, in the region of its surface, will be impregnated with the product to be dispensed when the roller is rolled over the floor surface and the product or the active ingredient of the product can subsequently, over a brief period following the opening and closing of the door, allow the product to evaporate therefrom over a short period of time.
It will be appreciated that other arrangements are possible. For example, rotation of the roller along the floor surface may serve to cock a spring mechanism operating a pump to dispense the product into the atmosphere or to actuate briefly an aerosol mounted on the device.
If desired, the device may incorporate a catch which can be operated manually or by foot, to inhibit rotation of the roller and to cause the device to act as a door stop.
In further variants, the device may be adapted to be secured to a wa
