Cleaning device
A device for cleaning a surface comprises a pressurized container containing a cleaning composition; a nozzle through which the composition is arranged to be dispensed, in use, upon an actuation of a valve; a shroud attached to the container and surrounding the nozzle. The shroud has a hollow generally cylindrical portion adjacent to the nozzle for guiding the dispensed product in the direction in which it leaves the nozzle, and a flared portion at the end of the cylindrical portion furthest from the nozzle forming a spreading plate for guiding the dispensed product laterally when in contact, in use, with a surface to be cleaned. The nozzle is arranged to be actuated by movement of the container towards the shroud. The device comprises a reservoir. The nozzle and shroud are configured so that, in use, the cleaning composition is directed across the surface to be cleaned and into the reservoir. The device comprises a latch movable into a blocking position upon actuation of the device in which position it blocks a further actuation of the device. The latch is releasable to a position in which the device can be further actuated. The latch is arranged to be moved to an emptying position in which the reservoir can be emptied before it can be moved to the actuating position.
1. A device for cleaning a surface comprising:
a pressurised container containing a cleaning composition;
a nozzle through which the composition is arranged to be dispensed, in use, upon an actuation of a valve; and
a shroud attached to the container and surrounding the nozzle;
the shroud having a hollow generally cylindrical portion adjacent to the nozzle for guiding the dispensed product in the direction in which it leaves the nozzle, and a flared portion at the end of the cylindrical portion furthest from the nozzle forming a spreading plate for guiding the dispensed product laterally when in contact, in use, with a surface to be cleaned;
wherein the nozzle is arranged to be actuated by movement of the container towards the shroud;
a reservoir, wherein the nozzle and shroud are configured so that, in use, the cleaning composition is directed across the surface to be cleaned and into the reservoir; and
a latch movable into a blocking position upon actuation of the device in which position it blocks a further actuation of the device, the latch being releasable to a position in which the device can be further actuated, the latch being arranged to be moved to an emptying position in which the reservoir can be emptied before it can be moved to the actuating position.
2. A device according to claim 1 , wherein the shroud is relatively movable with respect to the reservoir and is biased to a closed position in which it closes the reservoir.
3. A device according to claim 1 , wherein the latch is provided with at least one tooth or groove which engages with a respect groove or tooth in the surrounding housing to lock the latch in position with the reservoir open.
4. A device according to claim 1 , wherein the spreading plate is annular and centered on the cylindrical portion.
5. A device according to claim 1 , further comprising a spacer to maintain a predetermined distance between the spreading plate and the surface to be cleaned.
6. A device according to claim 1 , wherein a containment ring surrounds the spreading plate to confine the cleaning composition.
7. A device according to claim 5 , wherein the containment ring is the same component as the spacer.
8. A device according to claim 1 , wherein the reservoir is an annular chamber which is positioned above the spreading plate and around the hollow cylindrical portion.
