Description
FIELD OF THE INVENTION
[0001] This invention relates to dispensing means for a liquid, in
particular to dispensing means for delivering a dose of a liquid
product into a lavatory bowl.
BACKGROUND TO THE INVENTION
[0002] Toilet bowls require care to prevent the buildup of
unsightly deposits, to reduce malodour and prevent the growth of
bacteria. There are in existence many forms of toilet bowl cleaning
products. One type of product comprises a solid block of cleansing
and freshening agents that is suspended from the rim of a toilet
bowl in a container placed in the path of the flushing water. U.S.
Pat. No. 3,529,309 shows an example of this type of toilet bowl
cleaning product. Unfortunately, solid cleaning blocks have a short
lifetime and the release of cleansing and freshening agents varies
as the block deteriorates.
[0003] Toilet cleaning systems that use liquid cleaning agents have
also been developed. For example, European Patent Application
EP-0538957 discloses a cleansing and/or freshening unit capable of
being suspended from the rim of a toilet bowl for the purpose of
introducing liquid active substances from a bottle into flushing
water. Unfortunately, one problem with liquid dispensing devices
such as disclosed in EP-0538957 is that as the liquid level in the
dispensing bottle falls, the rate at which liquid is dispensed also
falls.
[0004] European Patent Application EP-0785315 describes a dispenser
that attempts to overcome the problem associated with devices such
as described in EP-0538957. This dispenser includes a dispensing
bottle that allows liquid to flow from it while permitting air from
outside the bottle to flow into it. Unfortunately, the device
described in EP-0785315 requires the use of a porous,
liquid-absorbing mass that is in continuous contact with the
cleaning liquid contained in the dispensing bottle. Apart from
being expensive to manufacture, this dispensing device is unable to
provide precise control over the volume of liquids dispensed in the
flushing water.
[0005] In addition to problems associated with rate of delivery of
liquid active substances, they also have problems associated with
the difficulty of incorporating certain actives, such as bleaches
and various hypochlorites, as these materials may affect properties
of the components of the liquid active substance. For example,
bleaches and hypochlorites will typically fade the color of a dye
and destroy a fragrance upon extended contact. Also, certain
incompatible cleaning actives may not be stable when mixed and
through the resulting chemical interaction, the efficacy of the
individual cleaning actives may be decreased. In particular, the
inability to incorporate bleaches and hypochlorites into a liquid
active substance is especially detrimental as bleaches and
hypochlorites are particularly effective in destroying bacteria and
preventing biofilm formation.
[0006] These limitations in liquid dispensing cleaning systems have
prevented their optimization.
[0007] There is a need for an improved device that can dispense
precisely controlled quantities of cleaning and freshening liquids
from under the rim of a toilet bowl, and that can deliver a greater
variety of cleaning actives to a toilet bowl, including
incompatible liquid active compositions.
SUMMARY OF THE INVENTION
[0008] According to a first aspect of the invention there is
provided dispensing means for delivering a dose of a first liquid
into a second liquid, the dispensing means comprising an enclosure
for accommodating the first liquid, and dispersion means, the
dispersion means being adapted to receive a dose of the first
liquid from the enclosure, and to deliver a dose of the first
liquid into the second liquid when subjected to a flow of the
second liquid, wherein the dispersion means comprises a structure
along which the first liquid is transportable and, in use,
substantially all of the surface area of the dispersion means is
exposed to the atmosphere.
[0009] The invention therefore provides dispensing means that, for
a given volume of the dispensing means, has a greater surface area
from which evaporation of the first liquid can take place than
known dispensing means.
[0010] Preferably the dispensing means is adapted to dispense a
plurality of individual doses of a first liquid product in
succession, one dose being delivered each time the dispersion means
is subjected to a flow of the second liquid.
[0011] In a preferred embodiment of the invention the dispensing
means is for suspension below a rim of a lavatory bowl, the first
liquid product then being a suitable additive to the water (forming
the second liquid) being flushed into the lavatory bowl. Suitable
additives include fragrances, surfactants, bleaches, dyes,
disinfectants, insecticides, deodorants and cleaning agents.
[0012] Where the first liquid product includes a fragrance, the
invention provides a dispensing means, which, when suspended below
a rim of a lavatory bowl, enables the fragrance to be released from
the dispensing means between flushes of the lavatory more
effectively than by known dispensing means.
[0013] The invention therefore further provides a dispensing means
that can deliver cleaning and/or freshening lavatory bowl treatment
preparations from under the rim of a toilet bowl before, during and
after flushing of the lavatory.
[0014] The structure along which the first liquid is transportable
may advantageously be provided with at least one internal channel,
which, in use, is exposed to the atmosphere so as to increase the
surface area of the structure available for evaporation of the
first liquid.
[0015] The structure may be provided in a range of shapes, e.g. a
cube, plate, ring, oval, sphere, rod, or any decorative shape or
mixture of shapes.
[0016] In the preferred embodiment of the invention, however, the
structure is a tube and, in use, an internal surface of the tube is
exposed to the atmosphere.
[0017] The structure may advantageously be formed with at least one
capillary channel for transporting the first liquid along the
structure by capillary action.
[0018] Alternatively, or in addition, the structure may
advantageously be formed from a porous material, preferably a
porous non-water-soluble plastics material, capable of transporting
the first liquid along the structure by capillary action. Suitable
non-water-soluble plastics materials include polypropylene and
polyethylene.
[0019] In use at least 65% of the surface area of the dispersion
means may advantageously be exposed to the atmosphere, and
preferably at least 75% of the surface area. In preferred
embodiments of the invention, in use, at least 85% of the surface
area of the dispersion means is exposed to the atmosphere.
[0020] According to a second aspect of the invention there is
provided dispensing means for delivering a dose of a liquid product
into a liquid, the dispensing means comprising an enclosure for
accommodating the liquid product, and dispersion means adapted to
receive a dose of the liquid product from the enclosure, and to
deliver a dose of the liquid product into the liquid when subjected
to a flow of the liquid, wherein a surface of the dispersion means
is curved such that the flow of the liquid, when incident upon the
surface, is drawn over at least a portion of the surface.
[0021] The term "liquid product" is intended to encompass
solutions, suspensions and gels.
[0022] The invention therefore further provides dispensing means
that can dispense a larger dose of a given liquid product into a
given flow of liquid than known dispensing means, because the flow
of liquid not only comes into contact with that part of the
dispersion means on which it is incident, but also comes into
contact with at least a portion of the dispersion means over which
it is drawn.
[0023] The dispersion means is preferably elongate and may, for
example, be oval in cross-section, or be shaped like an aerofoil.
Preferably, however, the dispersion means is cylindrical.
[0024] The preferred embodiment of the invention is a liquid rim
dispenser adapted to be suspended below a rim of a lavatory bowl,
the dispersion means being subjected to a flow of water upon
flushing the lavatory.
[0025] Where the dispersion means is elongate, the dispersion means
is preferably arranged such that when the dispensing means is
suspended below a rim of a lavatory bowl, the dispersion means is
substantially vertical, i.e. substantially perpendicular to the
flow of water.
[0026] Preferably the enclosure is divided into two separate
enclosures, each with a respective dispersion means, and the
surface of at least one of the dispersion means is curved such that
when the dispersion means is subjected to the flow of water, the
water incident on the surface is drawn over at least a portion of
the surface and directed onto a surface of the other dispersion
means.
[0027] The arrangement whereby the enclosure is divided into two
separate enclosures allows the dispensing means to deliver a
greater variety of liquid products into the lavatory bowl than
known dispensing means. In particular, this arrangement allows the
dispensing means to deliver two different liquid products into the
lavatory bowl and is useful where it is undesirable for the two
liquid products to be mixed before they are delivered into the
lavatory bowl, for example where one liquid product is a bleach
solution and the other is a fragrance, since the fragrance would be
broken down by the bleach solution, and the bleach solution would
be neutralised in breaking down the fragrance.
[0028] In this way most (or all) of the undesirable chemical
interaction between the two liquid products is preempted and a user
of the dispensing means will benefit from the superior properties
of each of the incompatible liquid products through a single
delivery of each of the liquid products.
[0029] Moreover, the arrangement whereby flush water incident upon
one of the dispersion means is directed onto the other dispersion
means results in relatively even delivery of the liquid product
from the two enclosures, rather than greater delivery of the liquid
product from the enclosure the dispersion means of which is
upstream in the flow of flush water, provided that the dispensing
means is suspended in the lavatory bowl with the correct dispersion
means upstream in the flow of flush water.
[0030] In the preferred embodiment the surfaces of both the
dispersion means are curved such that when either dispersion means
is subjected to the flow of water, the water incident on the
surface of the dispersion means is drawn over at least a portion of
the surface and directed onto a surface of the other dispersion
means.
[0031] With this arrangement it is immaterial which dispersion
means is upstream in the flow of the flush water, making the
dispensing means simple to install in the lavatory bowl.
[0032] Preferably the liquid product comprises at least one
fragrance ingredient having a ClogP of 3 or more and a boiling
point of 250.degree. C. or lower. This has been found to be
particularly effective at providing an odour counteracting and
freshening effect when used with the liquid rim dispenser of this
invention.
[0033] By way of explanation, the logP of many fragrance
ingredients have been reported. For example, the Pomona92 database
(available from Daylight Chemical Information Systems, Inc.
(Daylight CIS), Irvine, Calif.) contains many logP values, along
with citations to the original literature. However, the logP values
are most conveniently calculated by the "CLOGP" program, also
available from Daylight CIS. This program lists experimental logP
values when they are available in the Pomona92 database. The
"calculated logP" (ClogP) is determined by the fragment approach of
Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry,
Vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden,
Eds., p. 295, Pergamon Press, 1990, incorporated herein by
reference). The fragment approach is based on the chemical
structure of each fragrance ingredient, and takes into account the
numbers and types of atoms, the atom connectivity, and chemical
bonding. The ClogP values, which are the most reliable and widely
used estimates for this physicochemical property, are used instead
of the experimental logP values in the selection of fragrance
ingredients which are useful in the present invention.
[0034] In the fragrance composition art, some materials having no
odour or very faint odour are used in addition to fragrance
ingredients proper (those fragrance ingredients that give the
fragrance composition its fragrance) as diluents or extenders to
form a fragrance composition. Non-limiting examples of these
materials are dipropylene glycol, diethyl phthalate, triethyl
citrate, isopropyl myristate, and benzyl benzoate. These materials
are used, for example, for diluting and stabilising the fragrance
ingredients in fragrance compositions. For the purposes of this
specification, these materials are not counted in the weight
percentages of fragrance ingredients in fragrance compositions.
[0035] Where the liquid product includes a fragrance composition,
the fragrance composition preferably comprises at least 30% by
weight of at least one fragrance ingredient having a ClogP of 3 or
more and a boiling point of 250.degree. C. or lower; even more
preferably at least 40% by weight; and more preferably still at
least 50% by weight.
[0036] According to a third aspect of the invention there is
provided a liquid rim dispenser intended for suspension from a rim
of a toilet bowl adjacent a wall thereof, in the path of flushing
water during a flushing operation, said liquid rim dispenser
comprising a container for holding at least one liquid active
composition, a base for holding the container, at least one hollow
porous substrate supported by the base and means for suspending the
base from the rim of a toilet bowl, and wherein the internal
surface of the hollow porous substrate is open to the surrounding
atmosphere.

DETAILED DESCRIPTION OF AN EMBODIMENT
[0045] The enclosure of FIG. 1 is in the form of a container 2 that
has two compartments 3 and 4 divided by a partition 5 separating
liquid active compositions 12 and 13. Two outlets 6 and 7 are
fitted with sealing components 8 and 9. Each sealing component 8
and 9 has a respective outlet tube 10 and 11.
[0046] The container 2 may be made from any suitable material, such
as a plastics material (for instance polyethylene). Preferably the
container 2 is made from a transparent material to allow the level
of liquid active compositions to be viewed. The container 2 may be
manufactured by any suitable method, and may be a complete moulding
or separate units that may be joined together by any suitable means
such as by adhesive.
[0047] The liquid active compositions 12 and 13 may be the same or
different compositions. Additionally, they may be the same colour
or they may be differently coloured to differentiate them from each
other.
[0048] The dispersion means of FIG. 2 is in the form of a holder
14, to which two hollow porous cylindrical substrates 15 and 16 are
attached as shown. The holder 14 provides a receptacle for
receiving and supporting the container 2, and may be manufactured
by any suitable method, such as by injection moulding. The holder
14 has a strap 23 for suspending the holder 14 from a rim of a
toilet bowl.
[0049] The holder 14 allows for the two cylindrical substrates 15
and 16 to be alongside one another in a symmetrical arrangement.
The bottom surface 19 of the holder 14 has two annular receptacles
26A and 26B formed by two outer cylindrical walls 17 and two inner
cylindrical walls 18 arranged concentrically. The annular
receptacles 26A and 26B receive the hollow porous cylindrical
substrates 15 and 16.
[0050] Upstanding from the bottom surface 19 of the holder 14 are
two piercing elements 20. A vertical cylindrical wall 21 surrounds
each piercing element 20. The inside wall of each vertical
cylindrical wall 21 has a series of vertical grooves 22 that
function as air ducts.
[0051] Turning to FIG. 3, this shows container 2 fitted into the
holder 14 to make dispensing means in the form of a liquid rim
dispenser intended for suspension from a rim of a lavatory bowl
adjacent a wall thereof, in the path of flushing water during a
flushing operation.
[0052] The piercing element 20 of the holder 14 has entered and
broken the interior of sealing component 8 to allow a portion of
liquid active composition 12 to flow out of outlet tube 10. The
portion of the liquid active composition 12 is contained within the
vertical cylindrical wall 21. The height of the bottom of the
outlet tube 10 relative to bottom surface 19 limits the portion of
liquid active composition 12 contained within vertical cylindrical
wall 21 to a shallow depth of a few millimetres and this level is
maintained automatically in a manner not unlike that of a "chicken
feeder". The air ducts provided by the vertical grooves 22 maintain
atmospheric pressure above the liquid within the vertical
cylindrical wall 21.
[0053] Turning to FIG. 4, a series of slots 24 are spaced
equidistantly and adjacent to the inside surface of the vertical
cylindrical wall 21. Radial channels 25 formed into the upper
surface of bottom surface 19 radiate outwards from piercing element
20. The radial channels 25 provide a conduit to slots 24 and allow
liquid active compositions 12 and 13 to pass through bottom surface
19. The slots 24 are aligned to communicate the liquid active
compositions 12 and 13 between the two concentrically arranged
cylindrical walls 17 and 18 of the two annular receptacles 26A and
26B that support the hollow porous cylindrical substrates 15 and
16. It is essential that there are no gaps between the hollow
porous cylindrical substrates 15 and 16 and the two annular
receptacles 26A and 26B supporting them as this could lead to
liquid active compositions 12 and 13 becoming liberated on the
outer and/or inner surface of the hollow porous cylindrical
substrates 15 and 16 resulting in uncontrolled release of the
liquid active compositions 12 and 13. If required, the hollow
porous cylindrical substrates 15 and 16 may be fixed to annular
receptacles 26A and 26B through the use of any suitable adhesive,
but care must be taken not to block the pores of the hollow porous
cylindrical substrates 15 and 16.
[0054] FIG. 5 simply corresponds to FIG. 2 without the cut away
portion.
[0055] The hollow porous cylindrical substrates 15 and 16 become
loaded with liquid active compositions 12 and 13 from the top
downwards because liquid active compositions 12 and 13 pass down
through slots 24 and into the top of the hollow porous cylindrical
substrates 15 and 16. Capillary action plus gravity act to exert a
downward pull on the liquid active compositions 12 and 13 so that
the hollow porous cylindrical substrates 15 and 16 become charged
quickly with liquid active compositions 12 and 13. Once the hollow
porous cylindrical substrates 15 and 16 are loaded with liquid
active compositions 12 and 13 they retain them against the force of
gravity.
[0056] The liquid rim dispenser is intended to operate when mounted
on the rim of a toilet bowl and flush water is washed over the
hollow porous substrates 15 and 16. The liquid rim dispenser
dispenses amounts of the liquid active compositions 12 and 13 onto
the hollow porous substrates 15 and 16. The large surface area of
the hollow porous substrates, in comparison with prior art
dispensing devices, allows for increased evaporation of fragrance
and thus improved continuous air freshening as both the external
and internal surfaces of the substrates are exposed to the
atmosphere. When the toilet is flushed, water is directed over the
hollow porous substrate or substrates to mix liquid active
compositions with flush water and deliver them to the toilet bowl.
The mixing of flush water to any surfactant emanating from the
substrate is extremely efficient in generating large amounts of
foam.
[0057] After each flush, gravity pulls downwards any water
deposited onto the hollow porous cylindrical substrates 15 and 16
while at the same time pulling liquid active compositions 12 and 13
through the hollow porous cylindrical substrates 15 and 16 to
reload them.
[0058] It is believed that the liquid rim dispenser of the
invention is better able than known liquid rim dispensers to
prevent flush water from entering the dispenser to dilute the
liquid active compositions in the container compartments 3 and
4.
[0059] The liquid rim dispenser therefore can convey the liquid
active compositions from the container to the cylindrical
substrates in a controlled and consistent manner, resulting in a
controlled, consistent amount of the liquid active compositions
being delivered into the lavatory bowl with each flush.
[0060] The ability of the curved surfaces of the hollow porous
cylindrical substrates 15 and 16 to pull the tangential supply of
flush water around these surfaces is due to the Coanda effect and
allows whichever of the hollow porous cylindrical substrates 15 and
16 that is situated "upstream" to the flow of flush water to
deflect it onto whichever of the hollow porous cylindrical
substrates 15 and 16 that is situated downstream. This results in
liquid active compositions 12 and 13 being liberated at
approximately the same rate due to the flush water being
distributed fairly evenly across both substrates. FIG. 6 shows the
base of holder 14, with flush water F superimposed upon it. This
illustrates how flush water F is deflected from whichever of the
hollow porous cylindrical substrates 15 and 16 that is upstream to
the flow of flush water F onto whichever of the hollow porous
cylindrical substrates 15 and 16 that is downstream to the flow of
flush water F.
[0061] FIG. 7 shows the decrease in mass of a dispensing means in
the form of a liquid rim dispenser with a single compartment and a
single porous cylinder when repeatedly subjected to flush water in
a lavatory bowl. The straight-line characteristic of the graph
illustrates the controlled and consistent manner of delivery of a
liquid active composition by the liquid rim dispenser.
[0062] It will be appreciated by those skilled in the art that the
liquid rim dispenser of the present invention can be readily
adapted for use with a wide variety of liquid active compositions
to meet different criteria in terms of colour, foam forming, odour
release, cleaning, disinfection, desired number of flushing
operations per dispenser, and other considerations.
[0063] The rheological behaviour of the active compositions 12 and
13 are selected with regard to the pore size of the porous
substrates 15 and 16, to ensure there is no leakage and that the
active compositions are drawn through the porous substrates to
provide a sufficient dose of the active compositions. Optimum
flow-rate of the active compositions through the porous substrates
may be established by one skilled in the art through the use of,
for example, d'Arcy's Law: The flow rate is reliant on the size and
number of pores and fluid viscosity. To ensure that the liquid
active compositions 12 and 13 are dispensed at the same rate the
viscosities of the liquid active compositions should be similar,
and should lie within the range of 50 to 4,000 centipoises at
25.degree. C.
