Abstract:
1. A spraying system comprising a device with a refill of fluid therein, wherein the refill comprises a body forming a reservoir for the fluid and a spray head located at an uppermost part of the refill in fluid communication with the reservoir, and wherein the device comprises a housing adapted to receive the refill therein and having an aperture suitable for permitting the spraying of the fluid from an exit orifice of the spray head therethrough, the device further comprising actuation means configured for periodic actuation of the refill, wherein the device is provided with detection means that distinguish between at least one area of lower reflectance and at least one area of relatively higher reflectance on the spray head of said refill, and wherein the detection means only operates to distinguish between said areas of differing reflectance during the upward movement of the spray head, said upward movement being provided by the inherent resilience or internal pressure of the refill and without electrical power being applied to the actuation means.
