Description
The invention relates to a dispensing device for dispensing active
substance fluids into the flushing liquid in a toilet bowl, with
the features of the introductory part of claim 1.
[0001] The term active substance fluid means flowable, thus liquid
to viscous, in a given case gel-like or even pasty or granular or
otherwise pourable, active substance preparations with cleansing,
disinfecting, deodorising, bleaching or similar action
(particularly described in DE 199 30 362 A1, which is not prior
published, as well as in EP 0 775 741 A1 and EP 0 960 984 A2).
[0002] Dispensing devices of the usual kind are known in various
forms under the catchword "WC baskets". In the first instance,
dispensing devices are known for a single active substance fluid.
The active substance fluid is there disposed in a storage
container, which is fixedly arranged or exchangeably inserted in a
holder, with an outlet opening arranged at the base side when the
storage container is mounted at the holder.
[0003] In a first known dispensing device for a single active
substance fluid the active substance fluid is delivered by way of
an actuating element (for example, from an open-pore foam material)
saturated therewith and loadable by the flushing liquid (EP 785 315
A1). Here the outlet opening of the storage container is for the
most part closed after the pushing out of a closure part of the
storage container by a sealing element arranged at the holder in
stationary position, so that a flow path with only a small
cross-section is available for the seeping out of the active
substance fluid. The device functions with utilisation of the
capillary effect of the open-pore foam material. A similar
construction with a rib plate serving for the distribution is also
known.
[0004] In the case of both variants it has on occasions felt not to
be optimal that the outlet opening is in principle permanently
open, so that active substance fluid can continue to seep out over
longer term non-use of the toilet bowl.
[0005] Another dispensing device for a single active substance
fluid (DE 299 02 066 U1) has at the storage container a sealing
element which operates in valve-like manner and which normally
adopts a positive, closed closure setting in which the outlet
opening is closed. This happens under the action of the
gravitational force of a valve ball acting as a sealing element.
This sealing element can be displaced against the biasing force
into a release setting slightly freeing the outlet opening. An
actuating element constructed as a rocker and pivotably mounted on
a pivot axis at the holder serves for this purpose. The actuating
element has at one side of the axis a loading region having a
pan-shaped receptacle for flushing liquid. The arm of the actuating
element lying on the other side of the axis bears from below
against the sealing element. If the flushing liquid impinges on the
influencing region, then the actuating element is lifted off the
valve seat at the outlet opening by way of the actuating element
and slightly frees the outlet opening. The active substance fluid
can seep past the sealing element out of the outlet opening into
the current of flushing liquid flowing by or is entrained by the
flushing liquid. A dispensing device similar to the previously
explained dispensing device is known from DE 199 30 362 A1 already
mentioned further above but not prior published, the device having,
however, as actuating element a single-arm lever which is pivotably
connected at one end with the holder and at which the sealing
element is arranged between the end pivotably connected with the
holder and the loading region. This construction corresponds, in
particular, with a storage container exchangeably arranged at the
holder.
[0006] In the case of use of the previously explained dispensing
devices of the usual kind all components entering the flushing
liquid of the toilet bowl have to be included in common in the
active substance fluid. However, many active substance components
cannot be realised in a form stable in conjunctive storage.
Accordingly, a multi-chamber dispensing device has already been
proposed (EP 0 960 984 A2). This known dispensing device serves for
dispensing at least two different or equally solid, gel-like, pasty
or liquid media in liquid or aqueous form into a toilet bowl. A
container, which has at least two independent chambers arranged
adjacent to one another for storage of the media, is disposed at a
holder able to be suspended at the edge of the toilet bowl. Each
chamber has a dispensing device with a dispensing tubelet which
exits into the environment by one free end thereof via the base of
the container and is surrounded at the other free end thereof in
fluid-guiding manner by a cover. The two chambers of the container
can be filled via slot-like passages of a cover part by flushing
water flowing over, which then issues into the toilet bowl in the
manner of a siphon or overflow by way of the dispensing tubelet
with entrainment of the respective active substance. The separation
of the chambers in the container has the advantage that different
media can be used which would otherwise adversely influence one
another in their desired effect in the case of common storage in
only one chamber. In addition, the consistency of the media can be
different in the different chambers.
[0007] In the dispensing device explained above the principle of
functioning of known "WC baskets" is utilised, according to which
the flushing water flowing over from above flows into the chambers
containing the active substance fluid, detaches parts of the active
substance material and, with entrainment thereof, flows back out of
the chambers. In that case the problem exists that a substantial
liquid level is left behind in the chambers by the siphon action
effected here. The action of the flushing liquid on the active
substance fluid in the respective chambers thus continues even when
the flushing process has long been concluded. The consumption of
active substance fluid cannot, in practice, be controlled in
optimum manner.
[0008] There is also known a double-chamber dispensing device for
like or different gel-like active substance fluids (WO 92/20876
A1), in which the outlet openings are executed as perforations in
the storage containers at the base and are permanently open. Due to
the viscosity and surface tension of the gel, this normally cannot
exit by itself under gravitational force. Partial quantities of the
active substance fluids can be discharged only by flushing liquid
which runs over and which enters from below into the outlet
openings and etches to some degree the gel near the outlet
openings. In this double-chamber system it is thus similarly the
case that the outlet openings are basically permanently open, so
that also with longer-term non-use of the toilet bowl the active
substance fluids can either seep out or solidify under the
influence of the ambient atmosphere and thereafter are no longer
activatable.
[0009] The teaching is based on the problem of optimising the known
dispensing device explained in the foregoing, for dispensing active
substance fluids from at least two mutually separate storage
containers, with respect to possibility of control of the
dispensing of the active substance fluids.
[0010] The set problem demonstrated in the foregoing is solved, in
the case of a dispensing device with the features of the
introductory part of claim 1, by the features of the characterising
part of claim 1. According to the invention the storage containers
are protected against the entry of flushing liquid into the
interior thereof and only active substance fluid issues from the
outlet openings of the storage containers. This is realised in the
manner that with each flushing process the dispensing of a partial
quantity of the active substance fluid into the flushing water
takes place from each storage container.
[0011] In the sense of solution of the set problem defined in the
foregoing an embodiment of the dispensing device, which is in
accordance with the invention, according to claim 16 is
particularly advantageous. A positive closure of the outlet
openings is advantageous in this concept particularly for the
purpose of defined dimensioning of the partial quantities and for
the purpose of protection of the active substance fluids in the
storage containers in the case of non-use in the longer term.
[0012] The technical principles of dispensing devices for a single
active substance fluid, which are known in the state of the art and
which have already been comprehensively explained further above,
are available for realisation of the construction according to the
invention. In particular, reference must be made for this purpose
to the state of the art discussed further above.
[0013] Preferred embodiments and developments of the teaching are
the subject of the subclaims.
[0014] Moreover, a preferred embodiment of the invention is
explained in more detail by reference to the drawing, in which:
[0015] FIG. 1 shows a preferred embodiment of a dispensing device
according to the invention, in a plan view,
[0016] FIG. 2 shows a section through the device of FIG. 1 along
the line II-II and
[0017] FIG. 3 shows a section through the device of FIG. 2 along
the line III-III.
[0018] The dispensing device illustrated in the drawings serves for
dispensing of at least two active substance fluids into the
flushing liquid which is flushed into a toilet bowl. With regard to
what is to be understood in the sense of the teaching as active
substance fluid, this has already been defined in the general part
of the description and reference may be made thereto.
[0019] Such a dispensing device comprises, in the first instance, a
holder 1 which can be suspended at the edge of the toilet bowl and
at least two mutually separate storage containers 2, 3, which are
provided in the holder 1, each for a respective active substance
fluid. The active substance fluids can be corresponding, different,
mutually compatible or mutually incompatible active substance
fluids. Two storage containers for two active substance fluids or
more storage containers for more active substance fluids can be
given.
[0020] According to the invention suitable active substance fluids
are, for example, aromatic phases, particularly perfumed aromatic
phases. Such aromatic phases usually contain at least one aromatic,
preferably perfume oil, at least one surfactant or emulsifier and
water as well as, in a given case, further ingredients such as
preservatives, thickeners, sequestering agents, colorants, further
surfactants or emulsifiers, stabilisers, descalers, etc.
[0021] According to the invention equally suitable as active
substance fluids are bleaching phases, particularly bleaching
phases containing chlorine, for example bleaching phases based on
hypochlorite, wherein the bleaching phases can usually contain,
apart from the actual bleaching agent and water, optionally further
ingredients such as thickeners, surfactants or emulsifiers,
neutralisers, colorants, aromatics, etc.
[0022] Further suitable active substance ingredients according to
the invention are descaling active substance phases, preferably
acidic descaling active substance phases. Such descaling active
substance phases can contain, apart from the actual descaler--this
is preferably an organic or anorganic acid--and water, optionally
further ingredients such as surfactants or emulsifiers, thickeners,
aromatics, preservatives, etc.
[0023] It is equally possible to use, as active substance fluids,
highly concentrated surfactant phases, so-termed "foam boosters".
Such highly concentrated surfactant phases can contain, apart from
the surfactants, also further usual ingredients.
[0024] According to the invention active substance fluids with an
antibacterial and/or fungicidal and/or antiviral active substance
phase are equally suitable, wherein the active substance phase can
contain, apart from the active substance acting antibacterially
and/or fungicidally and/or antivirally and water, optionally
further ingredients such as, for example, surfactants or
emulsifiers, thickeners, aromatics, preservatives, etc.
[0025] In addition, it is possible for the active substance fluids
to be active substance phases with an enzyme content. Such active
substance phases with enzyme content can contain, apart from the
enzyme or enzymes and water, optionally further ingredients such as
surfactants or emulsifiers, thickeners, aromatics, preservatives,
etc.
[0026] Equally, it is possible for the active substance fluids used
in accordance with the invention to be absorbent, particularly
odour-absorbent, active substance phases. These can contain, apart
from the absorption agent, particularly an odour-absorption agent,
and water, optionally further ingredients such as surfactants or
emulsifiers, thickeners, aromatics, preservatives, etc.
[0027] The dispensing device according to the invention offers, in
accordance with a special embodiment, the possibility of using
combinations of different active substance fluids in the storage
containers 2, 3, wherein according to a preferred embodiment one of
the storage containers 2, 3 contains an aromatic phase,
particularly as previously defined.
[0028] Examples of active substance fluid combinations to be used
are perfumed aromatic phase combined with chlorine bleach (not
stable in storage together with one another), perfumed aromatic
phase with highly concentrated surfactant phase (foam booster),
aromatic phase with descaling acidic active substance phase,
aromatic phase with antibacterial active substance phase, different
acid systems, aromatic phase combined with active substance phase
having an enzyme content, perfumed acid phase combined with
watercolouring phase, aromatic phase with odour-absorbent phase,
perfumed acid phase with available oxygen, perfumed acid phase with
active substance phase, thickened with polyacrylate, etc. Of
particular interest in that case are viscous to gel-like active
substance fluids with viscosities in the region of a few thousand
mPas, particularly 2000 to 5000 mPas, preferably 2500 to 3500 mPas
(measured by Rotovisko LVT, hydrometer 2, 6 rpm, 200.degree.
C.).
[0029] In the case of the illustrated dispensing device each
storage container 2, 3 has an own outlet opening 4 by way of which
the respective active substance fluid can be dispensed into the
flushing liquid. By contrast to the state of the art forming the
starting point for the teaching, it is now the case here that the
storage containers 2, 3 are protected against entry of flushing
liquid into the interior thereof. The outlet openings 4 of the
storage containers 2, 3 are then so arranged that only active
substance fluid issues. The dispensing of a partial quantity of the
active substance fluid from each of the storage containers 2, 3
into the flushing liquid takes place in each flushing process. In
the illustrated embodiment this is realised by the fact that the
outlet opening 4 of the respective storage container 2, 3 in use
setting, thus as illustrated in FIG. 2, is arranged at the base.
Flushing water flowing over always impinges laterally on the
storage containers 2, 3.
[0030] Many different possibilities exist for the arrangement and
mounting of the storage containers 2, 3 at the holder 1. In the
embodiment which to that extent is preferred and is illustrated in
the drawing it is provided that the storage containers 2, 3 are
mounted or mountable in the container 1 to be individually
exchangeable. An alternative consists in coupling the storage
containers 2, 3 together by means of an adapter or the like and
mounting them, thus coupled, in the holder 1. A further alternative
consists in directly coupling the storage containers 2, 3 together
and mounting them, thus directly coupled, in the holder 1. Finally,
it is also conceivable to construct the storage containers 2, 3 in
a common unitary housing, for example as separate chambers in a
cohesive housing, and then mount them in that form at the holder 1.
One or other variant can be selected according to preferences in
practice and the active substance fluids to be used.
[0031] The storage containers 2, 3 can be designed, as described in
the state of the art (DE 299 02 066 U1, DE 199 15 322 A1), to each
be individually refillable by way of a refilling opening optionally
equipped with a valve. In particular, in this case the storage
containers 2, 3 can also be fixedly mounted or constructed in the
container 1, thus a unitary arrangement closed in itself can be
selected.
[0032] The illustrated embodiment, however, shows the storage
containers 2, 3 as exchangeable single-use containers which will be
very widespread in practice. The illustrated and preferred
embodiment shows the storage containers 2, 3 arranged adjacent to
one another at the holder 1. The same applies to an arrangement of
the storage containers 2, 3 one behind the other. Alternatively, it
could also be provided to arrange the storage containers 2, 3 one
above the other for the purpose of product delivery in cascade
manner.
[0033] The illustrated and preferred embodiment further shows that
the storage containers 2, 3, which here are, in fact, individually
exchangeable, can be mounted in the container 1 by plugging in from
above (into use setting). Diverse other possibilities of fastening
come into question as alternatives. For example, it could be
conceivable to push the storage containers 2, 3 into the holder 1
from the side. It could also be conceivable to place the storage
containers 2, 3 laterally at the holder 1 and then pivot into the
use setting about a pivot axis. One or other variant can be
selected according to the respective construction of the outlet
openings 4 and the method of closure thereof.
[0034] In principle, it is possible to use as active substance
fluid, for example, gels with very high viscosity or pastes which
are not independently capable of flowing. In this case it can be
recommended for the storage container 2, 3 to have a flexible wall
portion or a flexible wall overall and an expulsion of the active
substance fluid disposed therein takes place by pressure loading of
the storage container 2, 3. This pressure loading can be exerted by
way of, for example, an appropriate mechanism via the flushing
liquid which flows over.
[0035] It has already been mentioned above that in the case of the
multi-chamber dispensing device according to the invention
dispensing mechanisms can, in principle, be used which are known
from the state of the art for dispensing devices for a single
active substance fluid. To that extent a constructional
possibility, which generally speaking goes back to EP 0 538 957 B1,
applicable in the present case is that a plate-shaped distribution
element is provided at the holder 1 and has a loading region flowed
over by flushing liquid during the flushing process, wherein the
interior of the storage container 2, 3 is disposed in permanent
connection with the distribution element by way of the outlet
opening 4, optionally with interposition of an arrangement
preventing free flowing of the active substance fluid. According to
a particularly preferred embodiment the plate-shaped distribution
element is associated in common with all storage containers 2,
3.
[0036] The illustrated and preferred embodiment depicts a solution
operating with an actively closing sealing element. Here the outlet
opening 4, which is arranged at the base, of the storage container
2, 3 is closed by means of, in particular, a sealing element 5. The
sealing element 5 is biased into the closed setting closing the
outlet opening 4 and is displaceable against the biasing force into
a release setting slightly freeing the outlet opening 4.
[0037] For displacing the sealing element 5 there is provided an
actuating element 6 which cooperates with the sealing element 5 and
which is transiently loaded by a force via the flushing liquid in
each flushing process to such an extent that the sealing element 5
temporarily adopts the release setting against the biasing force.
For that purpose a loading region 7 which is acted on by flushing
liquid during the flushing process and on which the flushing liquid
thus impinges during the flushing process is disposed at the
actuating element 6. The actuating element 6 is constructed as a
single-arm lever pivotably connected at one end with the holder 1.
The sealing element 5 is arranged at the actuating element 6 at a
specific spacing from the loading region 7. Due to the single-arm
construction of the lever forming the actuating element 6 (FIG. 3)
the effective direction of the force exerted by the flushing liquid
is aligned with the direction of opening of the sealing element 5.
The sealing element 5 can thereby be lifted from below from the
outlet opening 4 of the storage container 2, 3. It is thus possible
without further measures to exchangeably mount the storage
container 2, 3 without special constructional features.
[0038] In the illustrated embodiment the sealing element 5 is
arranged between the end, which is pivotably connected with the
holder 1, of the actuating element 6 and the loading region 7. The
opening path of the sealing element 5 is thus comparatively small
and opening takes place, as desired, with only a quite small gap.
Moreover, this gap is, with appropriate design of the sealing
element 5, opened asymmetrically, namely opening more strongly in
the direction of the loading region 7 so that the effective
substance fluid preferentially issues in this direction. That is
the direction for the flushing liquid, with which the effective
substance fluid then appropriately mixes. The effective substance
fluid can thus run on the upper side of the actuating element 6 in
the direction of the loading region 7 and already mixes on this
path with the flushing liquid which flows over.
[0039] It is possible to provide for the sealing element 5 to be
integrally formed at the actuating element 6. This is recommended
particularly in the case of design of the actuating element 6 from
a plastic material, particularly from plastic material capable of
injection moulding. In addition, the holder 1 can, in particularly
preferred manner, consist of plastic material, especially a plastic
material capable of injection moulding, preferably thermoplastic
synthetic material. Overall, it can be provided that the actuating
element 6 is integrally formed at the holder 1 and the biasing
force is produced by the inherent resilience of the actuating
element 6.
[0040] The illustrated and preferred embodiment is now
distinguished in particular manner by the fact that the actuating
element 6 is associated in common with the sealing elements 5 for
at least two storage containers 2, 3, preferably for all storage
containers 2, 3. There can be recognised in FIG. 1 in plan view the
wide actuating element 6, which is of plate-shaped construction,
with the equally wide, pan-shaped loading region 7 and the small
outflow openings 8 recognisable therein, all in the frame-shaped
base plate 9 of the holder 1. The arrangement of the outlet
openings 4 at the storage containers 2, 3 is matched thereto. In
particular, these containers are, with respect to the centre of the
overall dispensing device, constructed asymmetrically with outlet
openings 4 offset relative to the centre of the dispensing device
overall (FIG. 2). There is thereby obtained a concentration of the
active substance exit at a relatively narrowly defined region
regardless of the fact that two storage containers 2, 3 are
provided.
[0041] Finally, a dispensing, which is controlled in specific
manner, of active substance fluid from the different storage
containers 2, 3 can be realised in the manner that the flow
cross-sections at the outlet openings 4 and/or at the sealing
elements 5 are able to be determined and/or set to be
different.
[0042] Finally, there are a number of design possibilities of the
illustrated dispensing device in constructional respects,
particularly with regard to the arrangement and formation of the
outlet openings and sealing elements. In this connection, there is
a contemporaneously filed parallel patent application of the
applicant, to the disclosure content of which reference may be made
(DE . . . ). In particular, a simultaneous metering or a metering
delayed in time can be realised with the same or different
concentration from the different storage containers.
[0043] The present invention is further explained by reference to
the following examples, which do not, however, restrict the
invention in any manner. Different active substance fluid
combinations for the storage containers 2, 3 of the dispensing
device according to the invention are described in the

Production
[0113] Provide water. Spread in thickener at medium to high
rotational speed (about 800 rpm) (test by glass-plate test for
freedom from pinholing); if polymer particles are still present,
further agitation needed. Neutralise solution by NaOH. Stir in
perfume oil at reduced rotational speed.
