Abstract
The present invention relates to improved toilet dispensing devices for use in conjunction with a sanitary appliance particularly a toilet.
Claims21
A cageless lavatory dispensing device comprising:
- a hanger, having a hook end, which is adapted to be suspended from at least part of a rim of a toilet bowl, and depending from the hook end a stalk, a standoff element, and a support structure depending from said stalk, wherein the standoff element is positioned or located with respect to the total length of the hanger as measured from the end of the hook end to the distal end of the hanger, that the standoff element is within the lower half of this total length, and,
- a plurality of compressed solid blocks formed from an extrudate, wherein said compressed solid blocks comprises at least one chemical agent, which encase or enrobe part of said support structure or stalk and are adapted to be suspended within the interior of the toilet bowl, wherein the standoff element impedes physical contact between the compressed solid blocks and a sidewall of the toilet bowl adjacent to the compressed solid blocks so that a gap is formed between the sidewall and the compressed solid blocks;
- and,
- wherein the density of the compressed solid blocks is at least 1% greater than the density of the extrudate;
- and,
- wherein the at least one chemical agent is eluted or dissolved into water flushed over the compressed solid blocks 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 hanger having a hook end, a stalk depending from said hook end, a first support structure depending from said stalk and a second support structure also depending from said stalk, said hanger is adapted to be suspended from at least a part of the rim of a toilet bowl, and,
- a plurality of compressed solid blocks formed from an extrudate, with at least one of said compressed solid blocks encasing or enrobing a part of said first support structure, and at least one further of said compressed blocks encasing or enrobing a part of said second support structure, wherein each of said compressed solid blocks comprises at least one chemical agent, and wherein each of said compressed blocks are adapted to be suspended within the interior of the toilet bowl wherein a portion of said support structure or stalk is a stand off element which impedes physical contact between the compressed solid blocks and a sidewall of the toilet bowl adjacent to the compressed solid blocks so that a gap is formed between the sidewall and the compressed solid blocks;
- and,
- wherein the density of the compressed solid blocks is at least 1% greater than the density of the extrudate;
- and,
- wherein the at least one chemical agent is eluted or dissolved into water flushed over the compressed solid blocks 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.
