Abstract
A dispensing device comprising a body defining first and second compartments, separated by a flexible impermeable membrane. The second compartment is closed off by a semi-permeable membrane adjacent which a water container is disposed. An apertured delivery tube leads from the first compartment. The device may be used to dispense a cleaning, disinfectant and/or fragrancing gel into a toilet bowl. On flushing, water enters the container and migrates through the semi-permeable membrane, increasing the pressure in an osmotic agent or swellable hydrogel contained in the second compartment. This imposes a pressure on the flexible impermeable membrane to displace a gel from the first compartment into the toilet bowl through apertures in the tube.
