Description

The invention relates to a dispensing device for dispensing a particular cleaning, disinfecting and / or deodorizing agent fluid in the Rinsing fluid in a toilet bowl with the features of the preamble of Claim 1.

The term drug fluid means flowable, that is liquid to viscous, optionally also gelatinous or even pasty active substance preparations (in particular described in the non-prepublished DE 199 30 362 A1 and EP 0 775 741 A1 and EP 0 960 984 A2).

Dispensers of the type in question are under the keyword "toilet bowl" known in different versions.

First, a dispensing device is known, in which the active substance fluid via a so that it can be soaked, with the rinsing liquid constantly or intermittently Actuatable actuating element (eg made of an open-cell foam) is added (EP 0 785 315 A1). Here is the outlet of the Reservoir after pushing out a closure member of the reservoir from on the holder fixedly arranged sealing element largely closed, so that only a flow path with a small cross-section for leakage of the Drug fluids is available. The device works under use the capillary action of the open-celled foam. The capillary paths that the Substance fluid must cover, but are relatively long, so that they constipation tend. Moreover, it is occasionally perceived as not optimal that the Outlet opening in principle is permanently open.

Also known are dispensing devices of the type in question, which are based on a Art siphon effect based (DE 198 23 338 A1).

The dispenser of the type in question, from which the invention proceeds (DE 299 02 066 U1), realized on the reservoir a valve-like working Sealing element, which normally has a positively closed closed position occupies, in which the outlet opening is closed. This happens under Effect of a biasing force, there the weight of a sealing element acting valve ball. This sealing element can oppose the Biasing force in the outlet opening a little releasing release position be adjusted. Serves as a tiltable rocker trained, on a Swivel axis on the holder pivotally mounted actuator. At a Side of the axis, the actuator has a trough-like recording for rinsing fluid having loading area on the Rinse liquid impinges in a rinse. The one on the other side of the Axis lying arm of the actuator is from below as Valve ball executed sealing element. Meets the rinse liquid on the Influencing area, so is the actuator as the valve ball executed sealing element lifted from the valve seat at the outlet opening and releases the outlet a little bit. The drug fluid may be on Sealing element over from the outlet in the passing stream the rinsing liquid seep in or is entrained by the rinsing liquid.

The recording in the loading region of the actuating element has at least one small drain opening. This empties this recording after the end of the rinsing process slowly, so that the flow cross-section of Outlet opening is continuously reduced and the outlet finally is completely closed when the sealing element reaches the closed position Has.

The previously described function of the actuating element can be replaced by an additional, the sealing element in the direction of the closed position biasing Be supported spring. By a stop the movement of the Actuator limited in the direction of the release position.

In the previously described, known dispensing device of which the invention goes out, the sealing element is in the direction of the interior of the reservoir moved to release the outlet opening. The sealing element is accordingly mandatory part of the reservoir. This is true even if that Sealing element, as proposed there, in a variant on the corresponding Arm of the actuating element is articulated. That makes it necessary for the Permanently connect reservoir to the holder and in turn then by means of make a flap refillable (as provided in this prior art) or with replaceable attachable reservoir, the sealing element in to integrate the reservoir. Thus, the sealing element must be part of the Reservoir always be replaced with a replacement, what causes unnecessary costs.

From the above-mentioned, not previously published DE 199 30 362 A1 is a dispenser of the type in question is known in which the Actuator not stored as a rocker, but as a one-armed, one end executed on the holder hinged lever. There is the Sealing element on the actuating element between the hinged to the holder End of the actuator and the loading area, the Rinsing process is applied by rinsing liquid. To the To form the loading area is the relevant end of the actuating element arched pulled up next to the reservoir, is located So considerably above the sealing element. In this not in is prior art described dispensing device already realized in an appropriate manner that the reservoir without Another interchangeable, because the sealing element can remain on the holder, when the reservoir is replaced.

In replaceable storage containers, the outlet opening forms in the reservoir a valve seat for the sealing element on the actuating element. As a result, the force acts directly on the onset of the reservoir Actuator. This is especially important if the Outlet opening of the interchangeable reservoir is initially closed and by placing the reservoir a closure member over the Connection opening must be opened. You have to do that in any case Hold the actuator by hand when replacing the interchangeable Install reservoir on holder.

The teaching is thus based on the problem, which explained above, from Prior art known dispensing device with a Valve-like sealing element taking into account the Necessities of a replaceable reservoir to optimize.

The problem identified above is in a dispenser with the Features of the preamble of claim 1 by the features of characterizing part of claim 1. According to the invention Sealing action for the sealing element laid on a valve seat, in turn on the holder, not formed on the reservoir. This will be a possible exercise of force when replacing a reservoir relative to Holder, which is held anyway, not or practically not relative to Actuator. So you can optimize the respective areas specific, without negatively affecting the other area.

Of particular importance is the previously explained inventive Construction then, if the reservoir when putting on the holder or insertion into the holder is opened simultaneously, so a Aufstechspitze provided for an inwardly herausstoßbares closure part of the reservoir should be. This piercing tip can namely according to the invention the nozzle be assigned, the sealing element and the actuator remain of it unaffected.

Moreover, the dispenser according to the invention have all the advantages inherent in the own a dispenser with positively closing sealing element are. In particular, an application of the active substance fluid takes place only if actually a rinse takes place.

Preferred embodiments and further developments of the teaching are the subject of Dependent claims.

Of particular importance is the embodiment of the invention Dispensing device such that the sealing element on the actuating element is integrally formed. In particular, we recommend a Training of plastic, in particular of thermoplastic material.

Further, it is recommended that the actuator on the holder also in one piece to mold. As a result, an additional biasing spring is saved, because the Biasing force can be generated by the inherent elasticity of the actuating element Can, especially if you have a suitably elastic plastic used. Here in the prior art plastics can be determined, which are also in A limited, relevant for the spring force area a sufficient Stability have, even with a considerable period of use so not or hardly tire.

Further preferred embodiments and further developments of the teaching are Subject of the other dependent claims.

The dispensing device shown in Figs. 1 and 2 of the drawing is used for Delivery of a particular cleaning, disinfecting and / or deodorizing Active fluids in the rinsing fluid, with those in a toilet bowl 1 rinsed off. The dispenser first shows one at the edge of the Toilet bowl 1 hanging holder 2 with a usual, in plastic integrally formed headband 3, over the edge of the toilet bowl. 1 is curious.

In the holder 2, here interchangeable, mounted a reservoir 4 for the Active fluid 5, which is indicated therein. The active substance fluid 5 may be to be a common drug composition. This is already one above Cited quotation, whose disclosure content by this reference in the The disclosure of the present patent application is taken over.

The reservoir 4 has an outlet opening 6 which is attached to the holder 2 Reservoir 4 is arranged on the bottom side. This outlet opening 6th can be closed by means of a sealing element 7. It is in Fig. 1 closed. The sealing element 7 is in the outlet opening. 6 Closing closed position biased and against the biasing force in a release opening 6 a little releasing release position adjustable. The Release position shows Fig. 2.

For adjusting the sealing element 7 is a with the sealing element. 7 cooperating actuator 8 is provided, which at each Rinsing process by the rinsing liquid temporarily in the form of a force can be acted upon, that the sealing element 7 against the biasing force temporarily takes the release position. This is located on Actuator 8 acted upon by a rinsing process of rinsing liquid Beaufschlagungsbereich 9, so the rinse liquid during the rinse process incident. The actuator 8 is a one-armed, one end on the holder. 2 hinged lever executed. The sealing element 7 is on the actuating element 8 arranged at a certain distance from the loading area 9.

Due to the one-armed design of the actuating element 8 forming lever is the direction of action of the force exerted by the rinsing fluid force rectified with the opening direction of the sealing element 7. This can the sealing member 7 down from the outlet port 6 of the reservoir 4 take off. As a result, it is readily possible, the reservoir 4 without special design features interchangeable attach.

In the illustrated embodiment, it is provided that the sealing element. 7 between the hinged to the holder 2 end of the actuating element 8 and the Beaufschlagungsbereich 9 is arranged. This embodiment shows the Drawing. As a result, the Beaufschlagungsbereich 9 has the longer lever arm and the sealing member 7, the shorter lever arm of the executed as a lever Actuating element 8. The opening path of the sealing element 7 is thus comparatively low, the opening is as desired only with a whole small gap. Moreover, this gap with appropriate design of the Sealing element 7 asymmetrically open, namely more open in the direction the loading area 9, so that active substance fluid 5 in this direction preferably exits. This is the direction to the rinsing liquid with which the Active fluid 5 then mixed accordingly. The active substance fluid 5 can therefore be up the top of the actuating element 8 in the direction of Boundary area 9 run and already mixed on this route with the overflowing rinsing liquid. For this reason, that runs Actuator 8 from the sealing element 7 to the loading area 9 out straight or, as shown in FIG. 2, sloping. The statement applies in the rest for the Normal position of the dispensing device that they are intended in one Toilet bowl attached occupies.

The realized in the illustrated embodiment plate-like extension of the Actuator 8 to the loading area 9 gives the desired Flow area for the active substance fluid 5.

While in the starting point forming prior art, the drug fluid 5 runs directly from the outlet 6, is the embodiment provided that the actuating element 8 starting from the holder 2 obliquely sloping below the outlet opening 6 through to the loading area 9 extends. The active substance fluid 5 thus does not simply run down in an uncontrolled manner the toilet bowl 1, but runs on the actuator 8 in the direction the Beaufschlagungsbereiches 9 and is targeted in the mixing area steered with the rinsing liquid. This contributes to an optimization of Distribution of active ingredients in the toilet bowl 1 at.

It is further provided here that the sealing element 7 on the actuating element. 8 is integrally formed. This is especially recommended when designing the Actuating element 8 made of a plastic material, in particular from sprayable plastic.

The illustrated embodiment also shows that it is here at the reservoir 4 is a disposable part. The reservoir 4 is therefore replaceable and is thrown away after emptying. It is envisaged that the Sealing element 7 a Aufstechspitze 10 for an inwardly herausstoßbares Closing part 11 of the reservoir 4 has. In the illustrated Embodiment, the closure member 11 is a frictionally engaged in the outlet opening 6 of the reservoir 4 sitting plug. The closure member 11 can also integrally formed on a cap and a predetermined breaking point, in particular an annular predetermined breaking point with the edge in connection stand, wherein the predetermined breaking point by the insertion of the Aufsteckspitze 10th is broken (EP 0 785 315 A1).

Also, the holder 2 can in a particularly preferred manner of plastic, in particular made of injection-moldable plastic, preferably thermoplastic Plastic exist. Overall, it can be provided that the actuating element 8 on the holder 2 is integrally formed.

Fig. 3 shows a preferred embodiment of an integrally formed on the holder 2 Actuator 8. It can be seen that here the holder 2 a frame-like bottom plate 12, indicated by the reference numeral 12 (2), in which the actuating element 8 is formed. In this case, the bottom plate 12th executed here together with the actuator 8 as a plastic injection molded part.

It can now be provided that the biasing force for closing the sealing element 7 generated by the inherent elasticity of the actuating element 8 becomes. In the illustrated embodiment, this is further substantiated by that the connection area 8 'of the actuating element 8 on the holder 2 as Biasing spring designed and designed. The elastic spring action is so insofar initially produced by the connection area 8 '. The considerable Lever arm with which the on the loading area 9 of the actuating element 8 acting flushing liquid, thus leading to an elastic Depressing the actuating element 8 as indicated in Fig. 2. As a result, the active substance fluid 5 occurs in a small amount precisely metered from the released gap and runs on the actuator 8 in the direction of Boundary area 9. In this way, it already mixes with the Rinsing fluid and enters the toilet bowl 1 at the edge of the pool.

The embodiment shown in Fig. 1 and 2 shows that it is particularly is advantageous, the articulation of the actuating element 8 on the holder 2 between whose directed to the interior of the toilet bowl 1 outside and the Arrange outlet 6. As a result, the actuating element 8 extends further radially outwards in the direction of the outer edge of the toilet bowl 1 to under the gap, from the edge of the toilet bowl 1 when flushing the Rinsing liquid emerges. As a result, the active substance fluid 5 becomes the highest possible Position introduced into the toilet bowl 1 and unfolds its effect on the entire wall of the toilet bowl 1.

Not shown is initially a variant in which between the holder 2 and the actuating element 8 for realizing the biasing force an additional Biasing spring made of plastic or metal is provided. This one can too in turn, in addition to the connection area of the actuating element 8 am Holder 2 formed biasing spring be present.

The embodiment shown in Fig. 3, however, shows that here two additional, between the holder 2 and the actuator 8 acting Biasing springs 13, 14 are provided. The connection area 8 'of the actuating element 8 on the holder 2 acts here rather as a kind of hinge, though with a certain inherent spring elasticity, while the actual spring force effect is realized by the additional biasing springs 13, 14. In the it is shown as a one-piece plastic component, it is realized that the actuating element 8 with the holder 2 on the one hand in Connection area 8 ', on the other hand at two of the connection area 8' clearly spaced locations by means of an elongated, acting as a biasing spring Spring section 13 and 14 is connected. The two spring sections 13, 14, the form the two additional biasing springs are here laterally and symmetrically formed to the connection area 8 '. This is about S-shaped, partly on bending, partly stressed on torsion, in the plastic material in one piece shaped spring sections.

The embodiment shown in Fig. 4 also shows a frame-like Bottom plate 12 of the holder 2, in which the actuating element 8 is formed. Again, the connection portion 8 'of the actuating element 8 on the holder. 2 arranged in the middle. The also provided here, acting as biasing springs two laterally symmetrically arranged spring sections 13, 14 act here as elongated bending springs.

For the spring force, which should be realized appropriately for the bias, Preferably, the range is 0.01 N to 0.5 N, preferably about 0.05 N.

The illustrated embodiment also shows an embodiment thereof is characterized in that the movement of the actuating element 8 in the direction of Release position is limited by a stop 15. That way is ensures that the delivery amount of drug fluid 5 regardless of It is constant with which pressure the rinsing liquid on the Beaufschlagungsbereich 9 of the actuating element 8 impinges. For this stop 15 applies that this in the illustrated embodiment immediately below the Seal member 7 is arranged on the actuating element 8, so there the immediate limiting effect fulfilled. It is also possible to provide the stop 15 to make adjustable to different doses of To be able to realize active substance fluids 5.

In the embodiment shown in FIGS. 3 and 4 in a particularly preferred A version can be realized in which the stop 15 on the holder 2, and in particular on the frame-like base plate 12, in one piece is formed. If one sets in the injection tool lateral core pulls, so can for example, at the free edge of the actuating element 8 near the Implementation area 9. As an alternative, you can stop also attach as an additional part on the holder 2, in particular engage.

The illustrated embodiment also shows a particular embodiment of the actuating element 8, which has essential meaning. You could do that Actuator 8 in the loading area 9 simply as a smooth plate To run. In the prior art, a trough-like receptacle is realized here. The illustrated embodiment also shows in this area trough-like receptacle 16 for rinsing liquid. Indicated are the Rinsing fluid units as thick drops. Through this tub-like recording 16 will be at the end of a rinse the end of Actuator 8 is pressed down for a while, so that continue Active substance fluid 5, possibly to a lesser extent, from the outlet opening 6 exit. This applies until the restoring preload force is greater than is the force exerted by the supply of rinsing liquid, downward force. In that regard, it is further provided here that the actuating element 8 in Beaufschlagungsbereich 9, in particular in the receptacle 16, with at least one small drain opening 17 is provided. An appropriate solution is already available provided in the starting point forming state of the art.

In the embodiment of Figs. 3 and 4 are two drain openings 17th intended.

Number and cross section of the drain holes 17 determine the time that the "After-run" takes place after completion of a rinsing process. This is Suitably between 1 and 60 seconds, preferably between 5 and 10 seconds.

The illustrated embodiment does not show that the actuating element. 8 may have a plurality of small depressions in which small quantities the rinsing fluid are retained with drug fluid. In this case will after completion of the rinsing a remainder of mixture of rinsing liquid and Active fluid 5 held on the surface of the actuating element 8, so that also in the following period a room scenting takes place. There is also the Advantage that in the next flushing process directly drug fluid 5 of the Actuator 8 is available from, so not only the seepage the active substance fluid 5 from the reservoir 4 after opening the Seal element 7 must be waited.

You can also on the actuator 8 splash guard training provide that prevent flushing liquid from hemming to the reservoir 4 and optionally even in the stored in the reservoir 4 drug fluid. 5 entry.

Fig. 5 shows a specific example of a dispenser in Fig. 1 similar representation. The section shown here has more special features recognize this embodiment. It is provided that the holder 2 a Valve seat 18 for the sealing element 7 arranged on the actuating element 7 and a fluid passage 19 forming nozzle 20 has. The nozzle 20 is mounted on the end facing away from the valve seat 18 at the holder 2 attached Reservoir 4 connected to the outlet port 6. The sealing element 7 closes the outlet opening 6 of the reservoir 4 characterized in that it is on Valve seat 18 sealingly comes to rest. Through this construction, the Sealing effect of the sealing element 7 by means of the valve seat 18 to a point laid by the attachment of the reservoir 4, in particular the Attachment of the reservoir 4, not in terms of strength or practically not being affected. The sealing effect of the sealing element 7 is thus maintained without the need, the actuator 8 against injury.
