Abstract

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

First claim

The invention claimed is:

1. 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.

2. The device according to claim 1 wherein at least one surfactant is present as the at least one chemical agent.

3. The device according to claim 1 wherein the device further includes an air treatment dispenser.

4. The device according to claim 1 , wherein the density of the compressed solid blocks is at least 1.5% greater than the density of the extrudate.

5. The device according to claim 1 , wherein, in use, the standoff element has a dimension which is sufficient such that when the device is initially installed in a toilet bowl, the height of the standoff element is sufficient to impede physical contact between the blocks and the side wall adjacent to said blocks.

6. The device according to claim 1 , wherein the at least one surfactant is present in an amount of at least 25% wt. of at least one of the compressed solid blocks.

7. The device according to claim 6 , wherein the at least one surfactant is present in an amount of at least 49% wt. of the compressed solid blocks.

8. The device according to claim 1 , wherein at least one of the solid blocks comprises a sanitizing agent.

9. The device according to claim 8 , wherein the sanitizing agent is selected from: materials containing alkyl halohydantoins, alkali metal haloisocyanurates, bleach, essential oils, quaternary ammonium germicidal compounds and non-quaternary ammonium germicidal compounds.

10. The device according to claim 1 , wherein at least one of the compressed solid blocks comprises an anti-limescale agent.

11. The device according to claim 1 , wherein at least one of the compressed solid blocks comprises a hydrocarbon solvent constituent.

12. The device according to claim 11 , wherein the at least one of the compressed solid blocks comprises paraffin oil.

13. The device according to claim 1 , wherein at least one of the compressed solid blocks include a water-soluble film coating.

14. The device according to claim 1 , wherein the standoff element is positioned or located within the lower 40% of the total length of the hanger as measured from the end of the hook end, to the distal end of the hanger.

15. The device according to claim 14 , wherein the standoff element is positioned or located within the lower 33% of the total length of the hanger as measured from the end of the hook end, to the distal end of the hanger.

16. The device according to claim 1 , wherein the standoff element depends from the stalk of the hanger.

17. 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.

18. The device according to claim 17 wherein the hanger further includes a connector which is affixable to parts of each of the first support structure and the second support structure.

19. The device according to claim 17 wherein the first support structure and the second support structure are co-linear and perpendicular to an axis of the stalk.

20. The device according to claim 17 , wherein the chemical compositions of the compressed solid blocks encasing or enrobing a part of said first support structure, and the at least one further of said compressed blocks encasing or enrobing a part of said second support structure are different from one another.

21. The process for delivering a treatment composition to the interior of a toilet bowl, which process comprises:
providing a cageless lavatory dispensing device according to claim 1 ,
suspending the compressed solid blocks within the toilet bowl, and,
periodically flushing water about the exterior of the compressed solid blocks to elute the at least one surfactant to form a treatment composition with said water, which treatment composition provides a cleaning and/or sanitizing and/or disinfecting benefit to the toilet bowl.
