Dispensing Devices and Compositions Therefor

Abstract

The present invention relates to improved toilet dispensing devices for use in conjunction with a sanitary appliance, particularly a toilet.

1 . A cageless lavatory dispensing device comprising a hanger having a hook end adapted to be suspended from a part of a sanitary appliance, preferably the rim of a toilet bowl, and a compressed solid block comprising titanium dioxide and at least one chemical agent adapted to be suspended within the interior of the sanitary appliance. 
   
   
       2 . A device according to  claim 1  which comprises a hanger having a hook end, a stalk depending therefrom and a plate depending from the stalk. 
   
   
       3 . A device according to  claim 1  which comprises a hanger having a hook end, a stalk depending therefrom which includes a standoff section and a plate depending from the stalk. 
   
   
       4 . A device according to  claim 2  wherein the compressed solid block composition enrobes or encases part of the hanger. 
   
   
       5 . A device according to  claim 4  wherein the compressed solid block composition enrobes or encases the plate. 
   
   
       6 . A device according to  claim 1  wherein the device further includes an air treatment dispenser. 
   
   
       7 . A device according to  claim 1  wherein the compressed solid block composition comprises titanium dioxide and further comprises one or more chemical constituents such that when the block is immersed, rinsed or washed with water, said chemical constituents are 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 or other sanitary appliance being treated with the treatment composition. 
   
   
       8 . The device according to  claim 7  wherein the compressed solid block comprises at least one surfactant. 
   
   
       9 . A process for delivering a treatment composition to a sanitary appliance, preferably, to the interior of a toilet bowl, which process comprises:
 providing a cageless lavatory dispensing device according to  claim 1 ,   suspending the compressed solid block within the sanitary appliance, and,   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 a cleaning and/or sanitizing and/or disinfecting benefit to the sanitary appliance.
