Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to methods for
maintaining toilet bowls clean, and in particular to apparatus and
methods for preventing adherence of exudates on toilet bowl
surfaces.
BACKGROUND OF THE INVENTION
[0002] One well-recognized source of germs in modern households is
the toilet. Consumers spend considerable time and money in cleaning
and sanitizing toilets. Not only is this difficult task unpleasant
for many people, it also does not protect against proliferation of
germs between cleanings.
[0003] One alternative to continual cleaning of the toilet is the
use of in-tank articles that dispense a sanitizing agent into the
toilet tank. These articles employ a chemical or combination of
chemicals that release a sanitizing agent when in contact with
water. These articles have the advantage of providing continuous
cleaning and sanitizing of the toilet, at least while the
sanitizing agent remains in the tank.
[0004] There are numerous compositions known in the art which can
be compressed or tableted, providing a tablet, block or similar
article which may be placed in the tank of a toilet and dispense
cleaning active over a period of time.
[0005] Despite the large amount of products available for cleaning
toilet bowls, a problem still exists in maintaining the surface of
the toilet bowl clean. Fecal matter and other exudates often adhere
or cling to the surface of the bowl after flushing, even with the
use of in-tank toilet cleaners.
SUMMARY OF THE INVENTION
[0006] The present invention seeks to provide novel apparatus and
methods for preventing adherence of exudates on toilet bowl
surfaces. In the present invention, an anti-adherent agent, such as
a lubricant or surfactant, may be dispensed on the surface of the
toilet bowl prior to, during or even after depositing exudates in
the toilet bowl. The anti-adherent agent generally prevents fecal
matter and other exudates from remaining on the bowl surface after
flushing. The exudates may be washed away from the bowl surface
with the flushing water, leaving substantially no residue. After
each flush, the anti-adhering agent may be dispensed once again on
the bowl surface.
[0007] There is thus provided in accordance with a preferred
embodiment of the present invention a method for preventing
adherence of an exudate on a toilet bowl surface, the method
including applying an anti-adherent agent on a surface of a toilet
bowl, the anti-adherent agent being adapted to generally prevent an
exudate from remaining on a toilet bowl surface. The anti-adherent
agent may be applied prior to, during or after depositing an
exudate in the bowl. The anti-adherent agent generally prevents the
exudate from remaining on the surface of the bowl after flushing.
The anti-adherent agent may be reapplied on the surface after the
flushing.
[0008] There is also provided in accordance with a preferred
embodiment of the present invention an article for preventing
adherence of an exudate on a toilet bowl surface including an
anti-adherent agent applied on a surface of a toilet bowl, the
anti-adherent agent adapted to generally prevent an exudate from
remaining on a toilet bowl surface.
[0009] In accordance with a preferred embodiment of the present
invention the anti-adherent agent includes at least one of a
hydrophobic substance, lubricant, a cleaning agent, a bleach, a
surfactant, and a disinfectant.
[0010] Further in accordance with a preferred embodiment of the
present invention the anti-adherent agent includes at least one of
a tablet and a block placeable in the bowl.
[0011] Still further in accordance with a preferred embodiment of
the present invention the anti-adherent agent includes a drop-in
product placeable in a flushing liquid in the bowl.
[0012] Additionally in accordance with a preferred embodiment of
the present invention a dispensing device is provided for
dispensing the anti-adherent agent on to the surface.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The present invention will be understood and appreciated
more fully from the following detailed description taken in
conjunction with the appended drawing in which:
[0014] FIG. 1 is a simplified pictorial illustration of an article
and method for preventing adherence of an exudate on a toilet bowl
surface, in accordance with a preferred embodiment of the present
invention.
DETAILED DESCRIPTION OF THE PRESENT INVENTION
[0015] Reference is now made to FIG. 1, which illustrates an
article for preventing adherence of an exudate on a toilet bowl
surface, in accordance with a preferred embodiment of the present
invention.
[0016] The article may comprise an anti-adherent agent 10 applied
on a surface 12 of a toilet bowl 14. (A toilet seat is not shown
for clarity.) The anti-adherent agent 10 may generally prevent an
exudate from remaining on the toilet bowl surface 12. The
anti-adherent agent 10 may comprise, without limitation, a
lubricant (e.g., a mineral oil, baby oil, vegetable or fruit oil,
for example), a cleaning agent, a bleach, hydrophobic substance, a
surfactant (e.g., a detergent, a soap or a dishwashing liquid, for
example), or a disinfectant, or any combination thereof.
[0017] The anti-adherent agent may comprise, without limitation, a
tablet or block 16 placeable in toilet bowl 14. Additionally or
alternatively, the anti-adherent agent may comprise, without
limitation, a drop-in product 18 placeable in a flushing liquid in
toilet bowl 14.
[0018] The anti-adherent agent may be applied prior to depositing
an exudate in the toilet bowl 14. In such a case, the anti-adherent
agent may pre-coat the surface 12 so as to prevent exudates from
adhering thereto. Alternatively, the anti-adherent agent may be
applied during or after depositing an exudate in the toilet bowl
14. In such a case, the anti-adherent agent may break down the
adherence of exudates on surface 12 so that the exudates may be
flushed away without leaving residual matter or marks.
[0019] A dispensing device 20 may be provided for dispensing the
anti-adherent agent 10 on to the surface 12 of toilet bowl 14. For
example, a ring-shaped dispensing device 20 may be placed around at
least a portion of the bowl 14, such as inside and beneath the lip
of bowl 14. Dispensing device 20 includes therein the anti-adherent
agent 10, and may dispense the anti-adherent agent 10 manually or
automatically. For example, the weight of a person (not shown)
sitting on bowl 14 may trigger dispensing of anti-adherent agent 10
from dispensing device 20. As another example, dispensing device 20
may meter a portion of anti-adherent agent 10 at predetermined
intervals. As yet another example, dispensing device 20 may
comprise any kind of spray 22 that sprays anti-adherent agent 10 on
surface 12.
[0020] It will be appreciated by persons skilled in the art that
the present invention is not limited by what has been particularly
shown and described hereinabove. Rather the scope of the present
invention includes both combinations and subcombinations of the
features described hereinabove as well as modifications and
variations thereof which would occur to a person of skill in the
art upon reading the foregoing description and which are not in the
prior art.
