Definitions

  • the invention relates to a device for discharging apportioned quantities, for example, of a WC cleaning/disinfecting liquid and/or of a fragrance, having a supply container in which liquid product is accommodated, the liquid product, associated with a closed-off space, forming a first free liquid level.
  • a device for discharging apportioned quantities is known from DE-A 197 20 353.
  • a dropper bottle which is to be connected to a carrier.
  • the dropper bottle is upside down and, alongside a discharge opening located in the lower region of the device, has an air-admission opening. Spaced apart upstream of this region is a plate-like intermediate carrier in the manner of a half-shell, so that fragrance is supplied even in the absence of the flushing operation. Reproducible apportioned quantities cannot be achieved.
  • Such a configuration achieves, on a hydromechanical basis, a device for discharging precisely reproducible apportioned quantities. It operates in accordance with the birdbath principle, although, rather than being lifted out, the apportioned quantity passes an overflow on account of a difference in pressure initiated during the flushing operation. The positive pressure produced acts on the second free liquid level. This leads to the change in height with the result of a quantity of liquid product spilling out of the second collecting reservoir.
  • a product-protecting measure is constituted by the product opening having an openable closure. The liquid product is thus safeguarded before the use phase.
  • the second free liquid level is acted upon by a discharging air column located in another closed-off space.
  • This discharging air column forms a kind of “pushing member” which acts on the second free liquid level.
  • the corresponding movement is supplied by the medium which is present anyway.
  • the device is thus further characterized by the feature where the other closed-off space is produced by a change in closure level of a medium moved towards the first collecting reservoir.
  • the medium is water.
  • the medium is water flowing during toilet flushing, be this by descending access or a rising water level.
  • the apportioned quantity of liquid product discharged is correspondingly equalized in the closed-off space above the free liquid level, in the vacuum acting there.
  • the medium closes the space which is initially open to the atmosphere and, at the same time, forms a first equalizing channel. Equalization is completed before the closure.
  • the space-closing change in level results in the apportioned quantity being discharged.
  • a second equalizing channel in addition to the first equalizing channel, for a second equalizing channel to be provided, one equalizing channel constantly being open to the atmosphere.
  • the additional equalizing channel can open closer to the liquid-product side.
  • a further feature of the invention then consists in that the second equalizing channel opens out into a medium container which allows a level of medium which clearly exceeds the mouth opening of the closed-off space.
  • the second equalizing channel passes through a first medium container, and that the first equalizing channel opens out into the first medium container.
  • the first equalizing channel opens out into the first medium container.
  • a joint upstream medium container with a collecting shell on the base.
  • the collecting shell is configured in adaptation to the necessary measures in respect of disposing the device in a WC flushing cistern or in a WC bowl.
  • the invention provides that the outlet channels have different outlet cross-sections, in respect of an abrupt discharge of a liquid product or of a delayed discharge of a liquid product. The latter method of operation is favoured by the measure of one of the outlet channels allowing the liquid product to run onto the collecting shell.
  • the collecting shell here has the smaller outlet cross-section.
  • an exchangeable refill container In respect of exchanging used-up supply containers or of exchanging for those with a different type of active substance, it is proposed that the liquid product is accommodated in an exchangeable refill container.
  • This may be a continuous double container which has a partition wall and forms the two or more closed-off spaces.
  • the refill container has a product opening with an openable closure. It is only during first use that the liquid product is transferred to the discharging system, this, in turn, having the advantage of the liquid product being held in readiness in a protected state until the first use.
  • the means here are structurally straightforward and reliable in that the closure is formed as a piercing membrane.
  • the invention further makes a proposal of even independent importance, which ensures that only specifically envisaged media can be attached, which, in terms of the functioning in the case of a specific viscosity, etc.
  • this is embodied in that formed on the refill container, furthermore, is a part of a labyrinth which forms the first and/or second collecting reservoir and/or of the overflow.
  • this part of the labyrinth forms a kind of plug for the refill container.
  • the first and/or second collecting reservoir is formed with a base opening.
  • the collecting reservoirs are functional. Accordingly, the rest of the construction of the device is such that the refill container can be secured on a medium container which has an opening means for the product opening, the base part, which is necessary for the closure of the base opening in the refill container, being associated with this opening means, as a supplementary part of the labyrinth.
  • the labyrinth is complete and is activated, by way of medium, via the opening means.
  • the interface between the medium and container, forming the supplementary part of the labyrinth, and the channel-forming part of the labyrinth can be felt in an extremely favourable manner for attachment purposes.
  • the invention proposes, in respect of a refill container as supply container for a device for discharging apportioned quantities, for example, of a WC cleaning/disinfecting liquid and/or of a fragrance, that, in in a lower positioning region, the refill container has a product opening with an openable closure.
  • the device can be fitted out conveniently, in a stop-defined manner and with sufficient sealing by the refill container being configured such that it can be plugged onto an attachment cone.
  • a measure which provides further product protection is achieved in that the refill container has a connection adapter ring which is fitted onto a container neck and has a predetermined tearing closure membrane. The material of the ring can thus be selected optimally as far as the desired sealing is concerned.
  • a sufficiently load-bearing arrangement is achieved here if the inner attachment surface of the connection adapter ring has a height of 1 ⁇ 2 to 1 ⁇ 5 of the inside diameter of the same.
  • Such a plug-in connection is fully capable of coping with the customary flow conditions, for example, in the WC bowl.
  • the refill container has a fairly flat cross-section based on a rectangle. It is also favourable if the refill container has a cross-section based on a semicircle.
  • the cross-section of the refill container tapers, starting from its attachment base.
  • the attachment base is the cover of the refill container which, when the latter is disposed upside down, is directed downwards.
  • the tapering in relation to the rectangular cross-section of the refill container, has a dimension which is less than twice the inside diameter of the adapter ring.
  • a solution which is favourable in respect of the variability of the agents or active substance, and even of independent importance, consists in that two (or even more) refill containers are provided as individual containers which, together, supplement one another to form a cross-section based on a rectangle.
  • the refill container has two separate chambers.
  • the arrangement is further such that the two refill containers have neighbouring surfaces facing one another in the vertical.
  • the neighbouring surfaces allow the containers to be disposed such that each container is prevented from rotating.
  • the rotation-preventing proximity accommodates the attempts to provide as compact a construction as possible.
  • a refill container as supply container it is proposed, as a development, that the refill container has a product opening with an openable closure.
  • the closure is formed as a piercing membrane.
  • the invention additionally proposes that formed on the refill container, furthermore, is a part of a labyrinth which forms the first and/or second collecting reservoir and/or of the overflow.
  • the procedure, in relation to this part of the labyrinth is such that the first and/or second collection reservoir is formed with a base opening. This forms the accommodating part of a plug-in part.
  • the procedure in this respect is such that the refill container can be secured on a medium container of the device, which medium container has an opening means for the product opening, the base part, which is necessary for the closure of the base opening in the refill container, being associated with this opening device, as a supplementary part of the labyrinth.
  • the space-separating configuration in contrast, is such that the neighbouring surfaces are formed by a common partition wall. It is further provided that the neighbouring surfaces or the partition wall, in a horizontal cross-section, run in a manner in which they are based on a straight line. Contact abutment of the neighbouring surfaces may be present, so that even slight rotations of the individual containers in relation to one another are ruled out.
  • each individual container is further advantageous for the container-neck opening of each individual container to be offset in the direction of the neighbouring surface in relation to a vertical centre plane of the individual container. This can advantageously be utilized even in cases where it is possible for the attachment locations to be located in close proximity to one another, which makes it possible to produce a space-saving device. It is, moreover, possible for a different offset to be present, which has the advantage of it being possible, without departing from the outline of the refill container or of the device, for the individual containers to have different volumes.
  • the invention then relates to a refill container, if appropriate comprising two or more individual containers, characterized by the capability for being associated with a device according to the features of the preceding claims.

It is preferred, however, to have a two-part construction, that is to say by a combined refill container B comprising individual containers 2 ′, 2 ′′ which each contain a liquid product 1 and, together, supplement one another to form a cross-section which has an outline based on a rectangle 34 . You are referred, for example, to FIGS. 14 and 18. The rectangle 34 is indicated in FIG. 18 by supplementary chain-dotted lines.
  • a flat construction is sought for the device V. The ratio of width to length is around 1:6, preferably 1:4.
  • each product opening 6 of the refill container B or of the individual containers 2 ′, 2 ′′ has a first and a second collecting reservoir 10 , 11 disposed downstream of it, so that a discharging air column 14 is achieved in both infeeds. Accordingly, it is also the case here that the second free liquid level Sp 2 is acted upon by the discharging air column 14 which, at least in part, is the same for both second free liquid levels Sp 2 .
  • the zone formed by the medium container 17 functions as a collecting shell 35 .
  • the latter forms the lower termination of the medium container 17 and, on the side directed away from the attachment locations 33 , is connected to a shaft (passage) 36 which is open at the top.
  • the latter runs vertically and, in the upper region O of the device V, merges into water-feeding introduction slopes 37 . Parts of the flushing flow which come into contact there are fed, as a descending flow, by the introduction slope to the shaft 36 , forming the regulating medium 16 .
  • the shaft 36 and the introduction slopes 37 which project in the manner of wings and form collecting channels, lie within the flat construction of the device V and are curved at the rear, following the curvature of the wall of the WC bowl 31 .
  • the vertically oriented shaft 36 has a window-like bottom region.
  • the corresponding window is designated 38 . It is closed at the front of the device V and, as a flow bridge, forms the operative connection both with the space 13 , in which the discharging air column 14 of the two labyrinths is produced, and with the region of the equalizing channel II, which functions as an additional equalizing channel to the equalizing channel which exists on account of the space 13 and is marked I.
  • the batch being released in the labyrinth plane according to FIG. 21 is preferably incorporated rapidly into the flushing operation of the WC flushing cistern.
  • the attachment locations 33 are based on a console 41 which projects horizontally from the vertically oriented centre zone of the housing of the device V. From the console, in each case one attachment cone 42 , in the form of a tubular connector, extends in the direction of the upper region O of the device V. The tubular connector circumscribes a through-passage opening 43 in the console 41 .
  • the refill container B is plugged onto the free conical end of the attachment connector 42 in a substantially clamped and sealing manner.
  • the connection takes place in relation to a container neck 44 , which is formed indirectly as a correspondingly mating conical funnel.
  • the indirect connection is realized by the interposition of a connection adapter ring 45 . This is represented on an enlarged scale in FIG. 20 a.
  • connection adapter ring 45 .and projecting container neck 44 are latch-connected.
  • a U-shaped cross-section is selected as far as the ring 45 is concerned.
  • the U-web engages over the end border of the container neck 44 .
  • the latching comprises a latching bead 44 ′ of the container neck 44 and a corresponding latching groove 45 ′ of the connection adapter ring 45 .
  • connection adapter ring 45 forms a closure membrane 46 .
  • This is in sealed connection in relation to the free end of the inner leg of the U-shaped adapter ring 45 . It ( 46 ) is connected via a bridge section of reduced material thickness.
  • the bridge section is capable of predetermined tearing, leaving a hinge behind.
  • use is made of the free end section 42 ′ of the attachment cone 42 it being possible for this free end section to be introduced to an adequate depth. Apart from a remaining amount, this is reduced in height in the hinge-forming region (not illustrated, since it is easily conceivable).
  • the plug-in connection also has sufficient tilting stability since the inner attachment surface of the connection adapter ring 45 has an axial height of approximately 1 ⁇ 2 to 1 ⁇ 5 of the inside diameter D of the same. In concrete terms, the axial height is approximately a third of the said diameter.
  • connection adapter ring 45 The material of the connection adapter ring 45 is selected both in respect of good sealing and in respect of the predetermined tearing action.
  • a flow connection 47 Located beneath the through-passage opening 43 of the attachment cone 42 is a flow connection 47 , which is oriented as a transverse channel.
  • the flow connection slopes down in relation to the body of the device V, that is to say the fastening section of the console 41 . It opens out in the product opening 6 in each case in the second equalizing channel II, which forms the direct location of connection to the atmosphere.
  • the air-flow path in this respect is illustrated in the form of a chain-dotted line and is designated 48 .
  • the wall material of the flow connection 47 acts, at the same time, in the manner of a supporting strut in respect of the console 42 .
  • the cross-section of the refill container starting from the attachment base of the latter, the so-called termination wall 7 , tapers in the direction of the upper region O.
  • the tapering is present in both planes. You are thus referred to FIGS. 19, 20 and 21 , 22 . In both cases, the tapering merges into narrow convex curvature.
  • the design formula used here is one according to which the tapering, in relation to the rectangular cross-section of the refill container B, in the plane or the planes of the container neck 44 , has a dimension which is less than twice the inside diameter D of the connection adapter ring 45 .
  • the individual containers 2 ′, 2 ′′ in the case of the refill container B being constructed in two parts, are directed towards one another, this forming neighbouring surfaces 49 .
  • the latter are located so closely, and of identical surface areas, in front of one another that they prevent rotation.
  • the individual containers 2 ′, 2 ′′ which are thus configured substantially in the manner of direction indicators, cannot be rotated about the geometrical vertical axes of the attachment locations 33 , this being the case in spite of the rotationally symmetrical construction of these attachment locations.
  • These are located in the manner of a plate in a fixed fork formation in a securely positioned manner in the region of action of the WC flushing.
  • the neighbouring surfaces 49 run in a manner in which they are based on a straight line.
  • the corresponding plane, a plane of symmetry, is designated E-E (see FIG. 15).
  • each individual container 2 ′, 2 ′′ is offset in the direction of the respective neighbouring surface 49 in relation to a vertical centre line z-z.
  • the corresponding offset may be utilized such that individual containers 2 ′, 2 ′′ of different volumes may be fitted, this with the wall region of one neighbouring surface 49 projecting to a correspondingly great extent and with the wall region of the other neighbouring surface 49 being correspondingly set back.
  • the different offsets of the neighbouring surfaces 49 are not illustrated in the drawing.
  • FIG. 23 the intention is to explain a seventh exemplary embodiment, which, in terms of its basic technical concept, is closer to the exemplary embodiment according to FIG. 10.
  • the solution which embodies the seventh exemplary embodiment, however, is designed for feeding from two or more sources, as has basically been described in FIG. 12 ff . It is possible to make use of the arrangement variant for the channels, while maintaining an annular distribution of the channels with a now divided-off central channel (see basic diagram from FIG. 9). In this case, the basic principle described in detail above is maintained, and the labyrinth-like structure is merely realized in circle sectors.
  • the refill container B used in the manner of a supply container associated in an exchangeable manner with the device V, contains the liquid product 1 .
  • the refill container B is divided into chambers.
  • the chambers are designated 51 .
  • the chambers 51 In the lower region U of the refill container B, the chambers 51 each have a filling opening 52 . This is located in the base 53 of the refill container B.
  • a plug-like closure member 54 is used for this purpose. This has an elastic sealing collar 55 . The latter interacts with the inner surface of the filling opening 52 .
  • a widened stop flange 56 Located at the foot of the closure member 54 , which is plugged in from the outside, is a widened stop flange 56 . This can be connected firmly, for example by thermal means, to the underside of the base 53 .
  • the closure member 54 controls, via its product opening 6 , the quantity of WC cleaning liquid, disinfecting liquid and/or of fragrance which is to be discharged in an apportioned manner.
  • the abovedescribed labyrinth-like channel system which is incorporated in the closure member 54 , takes effect, this channel system being realized in the section which projects upwards in a tower-like manner and is accommodated partially in the interior of the respective chamber 51 .
  • the product opening 6 is itself closed. It has a closure 57 which can be opened when the device is used for the first time.
  • the openable closure 57 is formed by a piercing membrane, realized as the thin location of a sectoral cover 58 of the closure member 54 .
  • the base part 60 is a substantially cylindrical formation of the shell base 61 of the medium container 17 (you are referred to FIG. 26). It is a cylindrical hollow stub which is closed at the top. The hollow stub is fitted in a sealing manner in a correspondingly contoured, central plug-in cavity 62 of the labyrinth L in the region of the supplementary part T 2 .
  • a peripheral, sectoral annular step 60 ′ which is located to the side of the plug-like base part 60 and is at a lower level; forms a defined support for the part T 1 on the part T 2 , via an annular wall 54 ′ on the base of the labyrinth L and/or closure member 54 .
  • the lower end border of the same is upright.
  • the spike-like opening means 59 which projects upwards beyond the base part 60 such that it exposes the latter, is a cross-sectionally arcuate lance which is aligned with the lateral wall of the stub-like base part 60 .
  • the lance tapers to a point laterally and is sharpened, this resulting in the thin location of the cover 58 and labyrinth body being pierced without any difficulty.
  • the sector-like cross-section of the cover 58 continues into a vertical column 63 , via which the cut-open product opening 6 opens the flow connection of the liquid product 1 into the labyrinth L.
  • the cover 58 is located at the lowermost location of the chamber 51 . This allows discharging to take place in a residue-free manner.
  • the closure placed correspondingly in the positioning region is thus located in an extremely favourable position.
  • the product opening 6 which is pierced in the lower positioning region of the labyrinth L, is produced in a functionally reliable manner even in cases where a corresponding lance may be given a cross-sectionally T-shaped configuration.
  • the T-web is located along the angle bisector and reliably forces the cut-out tab of the thin location to the side.
  • the chambers 51 in the refill container B according to the seventh exemplary embodiment are divided by a common partition wall 66 .
  • the partition wall 66 leaves behind equally sized chambers 51 on both sides.
  • the centre-symmetrical configuration here also has the advantage of the relatively thin-walled refill container B being stabilized centrally.
  • the refill container B now has a cross-section based more on a semicircle.
  • the dome-like body thus has a rear wall 67 which is flattened in circle-segment form and is directed towards the fold-out end section of the carrier 32 .
  • the partition wall 66 which helps to form the chambers is rooted in the centre of this rear wall.
  • the chamber-bounding neighbouring surfaces 49 are integral with the partition wall (see FIG. 26).
  • the abovedescribed vertical rear wall 67 is not located along the diameter line of the approximately semicircular cross-section. It clearly extends beyond the equator.
  • the foot region of the band-like, elastic carrier 32 has a seat-like step 68 , forming a bottom region under which it is possible to engage.
  • the cross-sectionally circular base region 69 of the refill container B consequently grips under this bottom region, and the latter is secured against vertical yielding and, for all practical purposes, is locked (see FIG. 25).
  • the angling of the refill container B which takes place until the latter engages under the step 68 , is slide-guided, to be precise by a hook-in connection between the upper end of the carrier 32 and the head portion of the refill container B.
  • the refill container B on its side which is directed towards the rear wall 67 , the refill container B has hook-in arms 70 which are directed towards one another. These are located in the open inlet of a longitudinal groove 71 .

  • Upright directing-wall sections 75 extend above the shell base 61 . These sections are positioned such that medium 16 which streams into the medium container 17 via the filling opening 18 is directed onto the lower inlet 15 ′ of the channel 15 , so that the discharging air column 14 is formed in an effective manner.
  • the directing-wall section 75 which runs in the transverse centre and is directed away from the carrier 32 , may simultaneously serve for supporting the angled-in, lowered refill container B. In this case, however, height coordination in relation to the base part 60 is necessary.
  • the base region 69 which basically is itself substantially circular, has, in the downward direction, an encircling plug-in border 76 . This passes into vertical slots 77 of the directing-wall sections 75 . These taper in the plug-in direction (see arrow in FIG. 36). This subjects the parts B and 17 to a centring action. In order to allow the abovementioned tilting position of the refill container B, the plug-in border 76 is cut away in the planar region of the rear wall 67 . A downwardly projecting nose on the base region 69 has a stop-defining function.
  • the predominantly circular base region 69 merges into a trapezoidal outline, to be precise from the plane of the rear wall 67 .

  • the deflecting wall may be attached via webs with a spacing function.
  • this version of the device V may also be associated with a second channel guide, which assumes the task of the equalizing channel II explained above. This second equalizing channel would be pierced on the refill container B in the manner described.
  • FIG. 39 shows a supply container in an illustration like that in FIG. 26, but with a plug-in and sealing variant being represented
  • FIG. 40 shows a view from beneath of the upper section of the refill container.
  • each chamber 51 has a dedicated sealing lip 79 .
  • This is in the form of a round plug-in mouth and, at the same time, carries a latching rib 80 .
  • the latter extends from the inside of an upwardly projecting annular wall 82 of the labyrinth L.
  • a likewise upwardly projecting inner annular wall 83 Located concentrically in relation to the annular wall 82 is a likewise upwardly projecting inner annular wall 83 .

Extending from the underside of the latter are fastening means (not illustrated specifically) for securing the refill container B on the base part of the device V. Latching may be used here, as is explained for the region of the reference numerals 80 , 81 .
  • each chamber 51 has a dedicated sealing lip 79 encircling it independently of the sealing lip 79 of the other chamber 51 , it is not possible for the different types of liquid product 1 to pass over from one chamber into the other.

These two channels terminate with a cover like that which is designated 58 , although in this case it is offset sectorally to the side in relation to the latter and is located approximately halfway up the tower-like labyrinth L. This results in an enlarged amount of space in the chambers 51 which can be used for the respective liquid product 1 .
