The present invention relates to a cageless lavatory dispensing device comprising a hanger (10) and a compressed solid block (50). The hanger (10) has a hook end (20) for suspending the dispensing device to a sanitary-appliance, and the compressed solid block (50) comprises at least one chemical agent. A process for delivering a treatment composition to a sanitary appliance is also disclosed. Said process comprises the steps of: providing and suspending a cageless lavatory dispensing device within the sanitary appliance; periodically flushing water about the exterior of the compressed block to elute at least one chemical constituent to form a treatment composition with said water, which treatment composition provides cleaning and/or sanitizing and/or disinfecting benefit to the sanitary appliance.
A cageless lavatory dispensing device comprising a single hanger having a hook end adapted to be suspended from a rim of a toilet bowl which toilet bowl includes an interior, a stalk depending from the hook end, and a generally planar plate depending from the stalk, said plate encased in a compressed and densified solid block formed from a perform having been compressed upon the plate, the block comprising at least one surfactant adapted to be suspended within the interior of the toilet bowl, and wherein when installed within the toilet bowl, the stalk and the plate are angled with respect to one another and that a gap is formed between the block and the interior of the toilet bowl such that when the block is immersed, rinsed or washed with flush water in the toilet bowl, said surfactant is eluted or dissolved into said water and forms a treatment composition which provides a cleaning and/or sanitizing and/or disinfecting benefit to the toilet bowl being treated with the treatment composition.
A cageless lavatory dispensing device comprising a single hanger having a hook end suitable for being suspended from the rim of a toilet bowl, a stalk depending from the hook end, and a generally planar plate depending from the end of the stalk, said plate being encased in a compressed solid block comprising at least one water soluble or water dispersible chemical agent, the block being adapted to be suspended, when installed, within the interior of the toilet bowl, the cageless lavatory dispensing device being characterized in that the stalk and the plate are angled with respect to one another at an angle between 100° and 170°, ensuring, when installed, that the compressed solid block remains in the flow path of the flush water, minimizing the likelihood of physical contact of the compressed solid block and the interior sidewall of a toilet bowl.
