Definitions

  • the present invention relates to a dispenser for cleaning liquids for toilet bowls, and more specifically to a multi-compartment liquid dispenser for toilets.
  • the dispenser of the invention can be used in toilet bowls and provides a distribution of maintenance fluids.
  • EP-A-1,287,211 discloses a toilet bowl care liquid dispenser. This distributor clings into the bowl by means of attachment and has a reservoir of maintenance liquid. For the distribution of the liquid, the tank has in its lower part a free opening of a size which prevents the flow of the maintenance liquid out of the tank in the absence of flush.
  • the tank is also provided with a tube, at one end of which opens the opening; the other end of the tube is open. The flow of water from the flush at the end of the tube or around the end of the tube causes the distribution of the liquid contained in the tank, by hydrodynamic effect.
  • WO-A-02 40791 and WO-A-02 40792 describe devices for dispensing cleaning liquids for toilet bowls. These devices have two separate compartments. The use of two separate compartments avoids the problems that can be generated by two-component mixtures in a single tank. These documents mention in particular a component against scale and a component such as bleach. The distributors proposed in these documents have two separate compartments or separate tanks, as well as two separate dispensing systems, for the distribution in the toilet bowl of the products contained in the two compartments. The devices described in these documents pose a first problem of complexity of the distribution device. There is also a second problem of adjusting the relative quantities of distributed products.
  • the distributor provides only one of the two functions.
  • the distribution of the different products contained in the tanks depends on the difference in viscosity between the liquids contained in the tanks.
  • the invention in its various embodiments, proposes a solution to one or the other of these problems, or both problems. It proposes a distribution system activated by flushing and where the distribution of the quantity of the different liquids is synchronized despite a difference in viscosity between the liquids of the tanks.
  • the invention proposes, in a device with multiple compartments, to use for the distribution of the liquid the solution described in the application EP-A-1,287,211
  • the dispenser therefore has a reservoir of cleaning liquids, with several compartments.
  • Each compartment is connected, via its lower part, to a free opening of a size that prevents the flow of maintenance liquid out of the tank in the absence of flushing.
  • the device further has a tube. At one end of the tube opens the openings of the compartments. The other end of the tube is open. In other words, the tube is common to the different compartments.
  • the distribution of the different liquids is carried out according to the hydrodynamic principle described below, when the water of the flush flows around the tube and, if necessary, goes up in the tube.
  • the overpressure created by the flow of water is identical for each of the compartments. This ensures the distribution of an identical amount of liquid from each of the compartments of the device, regardless of the position of the dispenser in the bowl and the way the water flows around the dispenser.
  • each of the compartments of the tank is provided in its lower part with an opening, which has a dimension such that it prevents the flow of liquid from the compartment in the absence of external stress.
  • the term "lower part” the part of the compartment in which the liquid is located when the dispenser is in position in the toilet bowl. This opening is free, in that it is not blocked by a plug, unlike that proposed in US-A-3,946,448 or by a device permeable to the liquid, such as a porous mass.
  • a common tube Below the openings of the compartments, in the direction of use of the dispenser, is provided a common tube.
  • the lower end of the tube is open or free, unlike the solution proposed in WO-A-01 02653 ; this avoids the difficulty of adjustment encountered in the device of this document.
  • the lower end of the tube is arranged so as to be in the path of the water flowing during a flush, taking into account where appropriate a guiding device.
  • the flow of water from the flush near the end of the tube causes the hydrodynamic effect of the suction of a given amount of the maintenance liquids out of the tank.
  • the different compartments are subjected to the same overpressure, because of the common tube, it is possible to adjust with great precision the distribution of the different liquids. Indeed, it is perfectly possible to adjust the amount of liquid dispensed by flushing by adapting the size of the openings. In addition, it is also possible to adjust the relative distribution speed of the liquids by adapting the size of each of the openings according to the rheological characteristics of the liquid contained in the corresponding compartment. In summary we can play on the size of the opening, the viscosity of the liquid or both to settle the quantity of liquid distributed by flush.
  • liquids dispensed are simply referred to as “maintenance liquids”; the terms “first liquid” or “second liquid” are used for the sole purpose of distinguishing between the different liquids.
  • first liquid or “second liquid” are used for the sole purpose of distinguishing between the different liquids.
  • FIGS. 1 to 3 show a first embodiment of a dispenser according to the invention with schematic views in frontal section and in side section and with a view from below.
  • the figure 1 shows a front sectional view of the dispenser of the figure 1 , the tank not being assembled to the dispenser.
  • the compartments 6 and 8 of the tank are separate from each other, which allows to change one or other of the compartments of the tank.
  • the compartments 6 and 8 can be twinned by means of a connecting piece fitting on the necks of the compartments.
  • the necks 26 and 28 of the compartments are closed by separate collars 40 and 42, each with a cover 44 and 46.
  • the figure 2 shows the body 2 of the dispenser, and one of the compartments of the tank 4. In the figure is shown only the body 2 of the dispenser, without the attachment means on the edge of the bowl. These can adapt in an adjustable or non-adjustable manner in an opening 10 formed on the body 2.
  • the body of the dispenser has a tube 12, with in its lower part a cutout 14, extending over a part of the perimeter of the tube. This cutting makes it possible to promote the rise of water in the tube 12, or vice versa, as a function of the position of the cut with respect to the direction of the flow of water coming from the flush.
  • the lower part of the tube is free, that is to say that it is not blocked by a porous device or other. The water of the hunt can go up in the tube.
  • the dispenser further has a guiding device 16, which in an exemplary embodiment has the form of a plate with curved edges.
  • the figure 8 shows a possible embodiment of such a guide device in perspective.
  • This guiding device makes it possible to guide the water from the flush to the tube, so as to promote the hydrodynamic effect leading to the distribution of maintenance liquids.
  • the curved edges improve the water guidance and the performance as the regularity of the distribution.
  • the guiding device 16 comprises water baffles 17, for example vertical walls arranged in the corners of the guide device 16. These walls 17 are provided in the vertical continuity of the guide tube 12 and thus allow channeling the flushing water to the tube 12.
  • the tube has an elongated shape and has in its upper part beveled areas 18 and 19, adapted to perforate a protective cover openings in the compartments of the reservoir.
  • the upper part of the tube is closed and has two openings 20 and 22 visible on the figure 1 .
  • these two openings are in contact with the liquids contained in the compartments of the tank.
  • Each of the openings has a size adapted to prevent the flow of the corresponding maintenance liquid out of the compartment in the absence of flushing.
  • Each of the openings 20 and 22 is disposed in a cylindrical portion 48 and 50 adapted to the shape of the neck of one of the compartments. Between the two cylindrical portions 48 and 50, the tube has a central portion 52. In this way, as shown in FIG. figure 1 in operation, the opening 20 (respectively 22) is in contact with the liquid contained in the compartment 6 (respectively 8).
  • the figure 3 shows a partial bottom view of the dispenser tank of figures 1 and 2 ; the two compartments 6 and 8 and the limits of the necks 26 and 28 are recognized. The locations of the openings 20 and 22 are also shown and the dashed line in the figure shows a possible shape of the tube 12.
  • the figure 4 is a front view of a second embodiment of the dispenser of the invention, the tank being assembled to the dispenser. This embodiment is similar to that of the figure 1 with the central portion 52 which is at the level of the plane of the openings 20 and 22. In this case the two cylindrical portions 48 and 50 are completely integrated in the assembly of the compression tube 12.
  • the reservoir is formed of two compartments 6 and 8 which are assembled, at their respective necks 26 and 28, with a collar 30.
  • This collar allows both to ensure the mechanical cohesion between the two compartments forming the reservoir.
  • the collar 30 has a seal 32 sealed on the respective openings of the compartments; the seal thus ensures the closure of the compartments before the reservoir is introduced into the dispenser.
  • the tank is removable, so as to allow the replacement of the tank; one could also provide a monoblock tank with the body of the dispenser.
  • the figure 7 illustrates an alternative embodiment, which may be applicable to different embodiments of the dispenser according to the invention.
  • the openings 20 and 22 are not centered on the necks of the compartments 26, 28, but are close to each other. This ensures a better equality of pressures at the openings and therefore a similar distribution of liquids.
  • the dashed line in the figure shows a possible shape of the tube 12 and the double line shows the edges of the collar 30.
  • the tube is in the central position relative to the necks of the bottles. This results in a tube of a smaller size, which facilitates the rise of the water flush in the tube and increases the pressure during flushing.
  • the tube 12 may have vertical walls, as illustrated in FIG. figure 3 , with openings 20 and 22 off-center necks and moved closer to each other.
  • the guiding device is formed of two plates 16 'and 16 "which are gathered in the vicinity of the free end of the tube 12.
  • a rib 54 may be provided at the level of the gathering area of the plates 16 16 "and extends substantially along a median axis between the two openings 20, 22 of the compartments 6, 8. This rib 54 has a limited height of a few millimeters; it does not prevent the flushing water from being distributed in the tube 12 to each opening 20, 22 but it limits the mixing of the liquids of each compartment at the guiding device.
  • one compartment may contain a tartar liquid having a low pH and the other compartment may contain a disinfectant liquid having a high pH.
  • a mixture of such liquids must not only be avoided in the compartments but also during distribution because such a mixture at high concentration produces harmful chlorine gases to breathe. When these liquids mix in the water of the hunt, the concentration decreases and the harmful effects disappear. It is understood that this embodiment of the guiding device can be combined with any of the embodiments described above as to the arrangement of the tube and compartments.
  • the Figures 12 to 14 illustrate a fifth embodiment of the invention wherein the dispenser further comprises a third compartment 7.
  • This third compartment 7 is not connected with a free opening opening in the tube 12 as the compartments 6, 8 of the reservoir but present at least one zone covered by a semipermeable membrane.
  • the third compartment is made of plastic and has a portion consisting of a semi-permeable membrane for the continuous diffusion of active substances, for example perfumes.
  • This third compartment 7 can be fixed to the body 2 of the dispenser ( figure 12 ) or the attachment means 11 of the body on the edge of the bowl ( figure 13 ) and thus be located outside the toilet bowl, or be attached to one of the compartments 6, 8 of the liquid reservoir to be dispensed during flushing ( figure 14 ).
  • the third reservoir 7 contains a perfume in liquid form and can be housed in a cavity in one of the compartments 6, 8 of the reservoir as shown in FIG. figure 14 .
  • the operation of the dispenser is as follows.
  • the tank On delivery, the tank is separated from the dispenser, as shown in figure 1 and at the figure 5 .
  • the user pushes the reservoir into the dispenser, as shown in figure 4 .
  • the bevelled zone 18 tears the lid of the reservoir, at the collar 40 of the compartment 6 and the bevelled zone 19 tears the lid of the reservoir at the level of the collar 42 of the compartment 8.
  • the cylindrical portions 48 and 50 in which the openings 20 and 22 are formed are then respectively applied against the collars 40 and 42 of the compartments of the reservoir. In this way, the openings 20 and 22 are respectively in contact with the liquids contained in the compartments.
  • the central portion 52 extends lower in the tube 12 than the openings 20 and 22, to provide around the cylindrical portions 48 and 50 an area allowing the passage of the necks of the compartments 6 and 8.
  • the central portion 52 extends inside the tube 12 higher than the maximum level of the flush water; in particular, the central portion 52 is above the cutout 14 in the tube 12. In this way, during a flush, the overpressure at the opening 20 is always equal to the overpressure at the level of the opening 22.
  • the bevelled zone 18 tears the seal of the reservoir, at the neck 26 of the compartment 6; the bevelled zone 19 tears the seal of the reservoir at the neck 28 of the compartment 8.
  • the surface 34 in which the openings 20 and 22 are formed then comes to bear against the necks 26 and 28 of the compartments of the reservoir. In this way, the openings 20 and 22 are respectively in contact with the liquids contained in the compartments. Ribs 36 and 38 on the side of the tank-facing surface 34 prevent any mixing between the liquids.
  • the configuration of the dispenser thus makes it possible to provide a removable reservoir, while ensuring that the openings 20 and 22 are brought into contact with the liquids contained in the compartments of the reservoir, without mixing the liquids of the compartments. As indicated above, this advantageous solution is not the only one possible.
  • the bevelled zone 18 tears the seal of the reservoir at the collar 40 of the compartment 6 and the bevelled zone 19 tears the seal of the reservoir at the collar 42 of the compartment 8.
  • the openings 20 and 22 are respectively in contact with the liquids contained in the compartments.
  • the guiding device comprises two plates 16 ', 16 "which guide the flushing water in the single tube 12 but separate the flow of each liquid to the bowl. , the overpressure prevailing at the level of the opening 20 will always be equal to the overpressure prevailing at the level of the opening 22 for an equal quantity distribution of the liquids of each compartment but these liquids will be mixed only in the bowl to avoid chemical reactions harmful to the user.
  • the dispenser is mounted in the toilet bowl.
  • the free end of the tube is in the vicinity of the path of the water flush, or even in the path of water.
  • the openings 20 and 22 prevent any flow of liquids out of the compartments 6 and 8.
  • the flow of water during the flush therefore causes an overpressure in the tube and the injection of water. air in the compartments through the openings 20 and 22.
  • the pressure in the tube decreases and the pressure created by the injection of air into the compartments causes the flow of liquids out of the compartments. This ensures the distribution of a certain amount of liquid at the end of each hunt.
  • the pressure in the tube is the same for both compartments. This ensures the same action of a hunt on both compartments, as explained above.
  • the shape of the tube 12 can be any; in the example, an elongate section has been chosen for the tube; this ensures that the tube has a maximum internal volume, for a given perimeter; this shape is also well adapted to circular openings in the necks or necklaces of the compartments.
  • the section of the openings 20 and 22 has a diameter of 1.5 mm in the embodiment of the Figures 1 to 3 , for a maintenance liquid having a viscosity of the order of 2000 mPa.s. More generally, the maintenance liquid may have a viscosity of between 10 and 4000 mPa.s, and the opening may have a diameter of between 0.2 and 15 mm.
  • the diameter or area of the opening can be determined experimentally for a given maintenance liquid. Even greater viscosities are possible, values between 2500 and 5000 mPa.s, and up to 6000 mPa.s are appropriate.
  • the diameter of the opening can then be chosen between 1.2 and 1.8 mm.
  • the invention avoids a constant flow of the maintenance liquid, and a loss of liquid in the absence of use of the toilet. It is also understood that the invention avoids the upwelling in the tank, and the dilution of the maintenance liquid. Furthermore, the device of the invention is immediately functional, unlike devices with a porous mass: from the first flush, or the second, a specific amount of maintenance liquid is distributed. The amount of maintenance fluid dispensed is independent of how often the dispenser is used.
  • the maintenance liquid may have a lower viscosity than in the distributors of the state of the art. This prevents blocking of the dispenser by thickeners, and improves its reliability.
  • the liquid of one compartment is dispensed faster than the liquid of the other compartment, by providing a larger opening or a larger number of openings.
  • the ratio between the quantities of liquids coming from the different compartments is always identical.
  • the Figures 15 to 18 show results of experiments on these multi-compartment distributors.
  • the abscissa has a number of hunts and ordinate the loss of liquid, ie the percentage of liquid dispensed by the distributor.
  • the figure 15 shows the experience results for a distributor with two compartments and two separate dispensing systems; each of the dispensing devices is of the kind described in the document EP-A-1,287,211 . Both liquids have viscosities of 3160 and 2650 cP. The distribution systems are identical. After about 500 hunts, the second compartment has emptied 80%, while the first compartment is emptied at 10%. The results of the test are explained by both the position of the dispenser and the difference in viscosity
  • the figure 16 shows the results of experiment for a distributor with two compartments identical to that used in the experiment of the figure 15 ; unlike the figure 15 both liquids have an identical viscosity of 5188 cP.
  • the first compartment is empty, while the second compartment is emptied at 25% after more than 600 hunts.
  • the results of the test are explained by the position of the dispenser, the distribution system of the first compartment being in the flow of the water of the hunt, while the distribution system of the second compartment is masked and receives only one flow weaker.
  • the figure 17 shows the results of experiment for a distributor with two compartments, of the kind represented in the figure 4 or 5 with water deflectors of the kind shown in figure 9 . Both liquids have an identical viscosity of 2700 cP. The figure shows that the two compartments empty simultaneously.
  • the figure 18 shows the results of experiment for a distributor with two compartments, of the kind represented in the figure 4 or 5 with water deflectors of the kind shown in figure 9 . Both liquids have viscosities of 2935 and 188 cP. The figure shows that both compartments empty simultaneously despite the difference in viscosity.
  • the dispensing tube could have another shape than that given in the exemplary embodiments.
  • the tube of the invention may have a section different from that which is proposed; for example, a square section may be used, the tube being simply formed of four walls which surround the opening provided in the lower part of the tank.
  • the length of the tube may vary from the embodiments, and it may well be smaller than the section.
  • the section of the tube can also cover the entire surface of the dispenser; one could in this case call the tube "skirt" or "compartment".
  • devices with two compartments have been described. More than two compartments can be provided. In this case, it is possible to use a tube common to all the compartments; this ensures the distribution of the same proportion of all products. Tubes common to only some of the compartments may also be used, since it is useful to control the relative distribution of only some of the liquids.
