Description

La présente invention a pour objet un dispositif pour la distribution d'un produit dans un réservoir d'une chasse-d'eau de WC. Les toilettes sont des installations pour lesquelles il est souhaitable de disposer de moyens de nettoyage évitant au maximum les interventions manuelles.The present invention relates to a device for dispensing a product in a tank of a toilet flush. The toilets are installations for which it is desirable to have means of cleaning avoiding to the maximum the manual interventions.

Parmi les procédés automatiques envisageables, celui qui présente le plus d'avantages consiste à placer dans le réservoir de la chasse- d'eau des produits désinfectants, détergents, désodorisants, colorants, etc...Among the automatic processes that can be envisaged, the one which has the most advantages consists in placing disinfectants, detergents, deodorants, dyes, etc. in the flush tank.

Pour réduire les interventions manuelles, il convient que la distribution des produits se fasse d'une manière automatique, que les remplacements des charges soient le plus espacés possible, et également rapides et faciles. Pour cela, il est souhaitable de disposer d'une charge contenue dans un récipient jetable, facile à fabriquer et réalisé en un matériau bon marché.To reduce manual intervention, the distribution of products should be done automatically, the replacement of loads should be as far apart as possible, and also quick and easy. For this, it is desirable to have a load contained in a disposable container, easy to manufacture and made of an inexpensive material.

Une première solution consiste à réaliser la dissolution d'un produit solide dans la totalité du volume du réservoir de la chasse d'eau. Un tel agencement n'est cependant pas très satisfaisant, du fait que le produit se dissout relativement facilement et que sa concentration dans le volume d'eau résiduel de la cuvette des WC est insuffisante. Il est donc intéressant de disposer d'un dispositif assurant le déversement du produit de nettoyage uniquement dans les derniers litres d'eau évacués du réservoir de la chasse, c'est-à-dire dans le volume d'eau demeurant dans la cuvette.A first solution consists in dissolving a solid product in the entire volume of the flush tank. However, such an arrangement is not very satisfactory, because the product dissolves relatively easily and its concentration in the residual volume of water from the toilet bowl is insufficient. It is therefore advantageous to have a device ensuring the discharge of the cleaning product only in the last liters of water discharged from the flush tank, that is to say in the volume of water remaining in the bowl.

Pour obtenir un tel résultat, il est connu (voir US-A 4307474) de mettre en oeuvre un dispositif de siphonage dont la réalisation matérielle se traduit par un orifice ou un conduit de sortie de la solution situé à la base du récipient.To obtain such a result, it is known (see US-A 4307474) to use a siphoning device whose material embodiment results in an orifice or an outlet pipe for the solution located at the base of the container.

Cet orifice ou conduit ne doit, bien entendu, pas être bouché, si bien qu'il n'est pas possible avec de tels dispositifs d'effectuer le remplissage de la charge en y coulant directement un produit à l'état liquide ou pâteux. La charge doit donc être introduite sous la forme d'une pastille, d'une charge unitaire emballée, ou de toute autre forme solide.This orifice or conduit must, of course, not be blocked, so that it is not possible with such devices to perform the filling of the load by directly pouring into it a product in the liquid or pasty state. The filler must therefore be introduced in the form of a pellet, a packaged unit filler, or any other solid form.

Or, les charges nettoyantes, colorantes et parfumantes, n'existent pas toutes prêtes et doivent être réalisées par le fabricant du dispositif de nettoyage, au moyen d'une opération préalable de formage appropriée comme le coulage dans un moule, le boudinage, l'extrusion, etc....However, the cleaning, coloring and perfuming fillers do not exist all ready and must be produced by the manufacturer of the cleaning device, by means of a suitable prior forming operation such as pouring into a mold, roving, extrusion, etc ...

La présente invention vise à remédier à ces inconvénients. A cet effet, dans le dispositif qu'elle concerne, comprenant un boîtier de forme générale parallélépipèdique destiné à être placé verticalement dans le réservoir de la chasse-d'eau, et dont la longueur est disposée dans le sens de la hauteur de celui-ci, et constitué par un fond en creux et un couvercle, le fond en creux comprend au moins deux alvéoles dont la première s'étend sur toute la longueur du boîtier et communique avec l'extérieur par des ouvertures débouchant à ou près de ses deux extrémités haute et basse, et dont la seconde s'étendant sur une partie de la longueur du boîtier à partir de l'extrémité haute de celui-ci comprend un cloison interne présentant un passage à au moins une de ses extrémités et délimitant une partie plus profonde destinée à contenir le produit actif qui peut être introduit par simple coulage à une température supérieure à son point de durcissement, et une partie moins profonde qui communique, à proximité de son extrémité inférieure, avec la première alvéole, les ouvertures de mise en communication des deux alvéoles entre elles étant constituées par des évidements débouchant dans les parois délimitant les alvéoles considérées, et les ouvertures de mise en communication de la première alvéole avec l'extérieur étant constituées par des évidements débouchant dans les parois délimitant les alvéoles considérées ou par des orifices prévus dans le couvercle.The present invention aims to remedy these drawbacks. To this end, in the device which it relates to, comprising a generally rectangular box intended to be placed vertically in the tank of the toilet, and the length of which is arranged in the direction of the height thereof. ci, and constituted by a recessed bottom and a cover, the recessed bottom comprises at least two cells, the first of which extends over the entire length of the housing and communicates with the outside via openings opening at or near its two upper and lower ends, the second of which extends over a part of the length of the housing from the high end thereof comprises an internal partition having a passage at at least one of its ends and delimiting a more deep intended to contain the active product which can be introduced by simple pouring at a temperature higher than its point of hardening, and a less deep part which communicates, near its lower end, with the first a cell, the openings in communication between the two cells between them being formed by recesses opening into the walls delimiting the cells in question, and the openings in communication between the first cell and the outside being formed by recesses opening into the walls delimiting the cells considered or by orifices provided in the cover.

La cloison séparant en deux parties l'alvéole contenant le produit actif, et la différence de profondeur entre ces deux parties, permet de couler un produit liquide dans la partie la plus profonde, sans que celui-ci puisse venir obturer les ouvertures de communication entre la partie la moins profonde et la première alvéole. En outre, la cloison assure, lors du remplissage et du vidage de l'alvéole contenant le produit actif, une bonne circulation d'eau améliorant la dissolution du produit.The partition separating the cell containing the active product into two parts, and the difference in depth between these two parts, makes it possible to pour a liquid product into the deepest part, without the latter being able to block the communication openings between the shallowest part and the first alveolus. In addition, the partition ensures, during filling and emptying of the cell containing the active product, good circulation of water improving the dissolution of the product.

Ce dispositif est de conception simple puisque le fond alvéolé peut être facilement obtenu par thermoformage, et que l'alvéole destinée à contenir le produit désinfectant, détergent ou désodorisant, peut être remplie par coulage de produit liquide ou pâteux, qui durcit in-situ, sans nécessiter le passage par un pastillage ou la réalisation d'un pain solide. Après durcissement de la matière active, le boîtier est fermé par mise en place du couvercle qui est fixé par exemple par collage ou soudure (thermique, haute fréquence, ultra-sons, etc...). Cela n'exclut pas l'utilisation d'un produit préformé qu'il suffit alors de mettre en place lors du remplissage.This device is of simple design since the honeycomb bottom can be easily obtained by thermoforming, and that the cell intended to contain the disinfectant, detergent or deodorant product, can be filled by pouring liquid or pasty product, which hardens in situ, without requiring the passage by a pastillage or the realization of a solid bread. After the active material has hardened, the housing is closed by fitting the cover, which is fixed for example by gluing or welding (thermal, high frequency, ultrasound, etc.). This does not exclude the use of a preformed product which then suffices to put in place during filling.

D'un point de vue pratique, lors du remplissage du réservoir de chasse-d'eau, la première alvéole se remplit complètement d'eau, l'air qu'elle contient initialement pouvant s'échapper par le ou les orifices débouchant dans sa partie supérieure.From a practical point of view, when filling the flush tank, the first cell fills completely with water, the air which it initially contains can escape through the opening (s) opening into its the top part.

La seconde alvéole contenant le produit actif ne se remplit que partiellement du fait de l'absence de possibilité d'échappement d'air à sa partie supérieure. Lorsque le réservoir est rempli, il se produit une dissolution lente de la matière active, produisant une solution concentrée dans la seconde alvéole.The second cell containing the active product is only partially filled due to the lack of possibility of air escape at its upper part. When the reservoir is filled, a slow dissolution of the active ingredient occurs, producing a concentrated solution in the second cell.

Lors de la vidange de la chasse-d'eau, ce n'est que lorsque le niveau atteint celui de l'orifice de communication entre les première et deuxième alvéoles que la solution concentrée en produit actif passe dans la première alvéole, où est réalisée une certaine homogénéisation de celle-ci et d'où elle est évacuée en fin de vidange du réservoir de la chasse d'eau.When emptying the flush, it is only when the level reaches that of the communication orifice between the first and second cells that the solution concentrated in active product passes into the first cell, where is carried out a certain homogenization of the latter and from where it is evacuated at the end of emptying of the flush tank.

La position du boîtier dans l'eau du réservoir est indifférente et il peut donc être placé à une hauteur quelconque sans que l'utilisateur ait aucunement besoin de repérer sa position. Le système d'attache ou de fixation de ce boîtier peut être quelconque; avantageusement, ce système peut être constitué par une languette solidaire du couvercle du boîtier.The position of the housing in the water of the tank is indifferent and it can therefore be placed at any height without the user having any need to locate its position. The attachment or fixing system for this box can be any; advantageously, this system can be constituted by a tongue integral with the cover of the housing.

La masse active ne se dissout que dans sa partie immergée, et descend lentement vers le fond de l'alvéole considérée, au fur et à mesure de son érosion, par dissolution.The active mass dissolves only in its submerged part, and descends slowly towards the bottom of the cell considered, as and when it is eroded, by dissolution.

Afin d'éviter que la masse active descende jusqu'au fond de cette alvéole, il est possible d'équiper celle-ci de plots ou d'une marche servant de support au produit à dissoudre.In order to prevent the active mass from descending to the bottom of this cell, it is possible to equip it with studs or a step serving to support the product to be dissolved.

Il a été découvert que, pour que ce boîtier fonctionne dans de bonnes conditions, il était avantageux de respecter des paramètres très précis.It has been discovered that, for this housing to function in good conditions, it is advantageous to respect very precise parameters.

C'est ainsi que la distance entre le fond de l'alvéole contenant la masse active, et l'orifice le plus bas de mise en communication de celle-ci avec la première alvéole, est de préférence inférieure à la moitié de la hauteur de cette dernière alvéole.Thus, the distance between the bottom of the cell containing the active mass, and the lowest orifice for placing the latter in communication with the first cell, is preferably less than half the height of this last cell.

Les positions et les sections respectives des orifices de mise en communication de l'alvéole contenant la masse active et de l'autre alvéole, sont de préférence telles que le volume liquide dans lequel est concentrée la masse active qui se déversera à chaque utilisation est compris entre 5 et 40 ml.The positions and the respective sections of the orifices for placing in communication the cell containing the active mass and the other cell, are preferably such that the liquid volume in which the active mass is concentrated which will spill with each use is understood between 5 and 40 ml.

En outre, la différence de hauteur entre les parois inférieures des deux alvéoles est avantageusement comprise entre 0,2 et 0,8 fois la hauteur de l'alvéole ne contenant pas le produit actif. La partie libre laissée par cette différence de hauteurs peut avantageusement être utilisée et conformée pour constituer une troisième alvéole destinée à distribuer un produit complémentaire du précédent (détergent, désinfectant, désodorisant, colorant, etc... ).In addition, the difference in height between the lower walls of the two cells is advantageously between 0.2 and 0.8 times the height of the cell not containing the active product. The free part left by this difference in heights can advantageously be used and shaped to constitute a third cell intended for dispensing a product complementary to the previous one (detergent, disinfectant, deodorant, dye, etc.).

La bulle d'air se formant à l'intérieur de l'alvéole contenant la masse active lors du remplissage du réservoir de chasse d'eau permet de régler la hauteur du liquide à l'intérieur de celle-ci. Le volume de cette bulle d'air est compris en pratique entre 0,3 et 0,95 fois le volume de l'alvéole.The air bubble forming inside the cell containing the active mass when filling the flush tank makes it possible to adjust the height of the liquid inside it. The volume of this air bubble is in practice between 0.3 and 0.95 times the volume of the cell.

Afin de fonctionner dans de bonnes conditions, le boîtier est dimensionné de telle sorte que le volume de la première alvéole est supérieur à la moitié de la différence entre le volume de la deuxième alvéole et le volume de la bulle d'air qui se forme dans celle-ci lorsque la chasse-d'eau est pleine. Pour pouvoir obtenir des rapports de volume satisfaisants, il est possible de réaliser des alvéoles dont les profondeurs respectives sont différentes.In order to operate in good conditions, the housing is dimensioned so that the volume of the first cell is greater than half the difference between the volume of the second cell and the volume of the air bubble which forms in this when the flush is full. In order to be able to obtain satisfactory volume ratios, it is possible to produce cells whose respective depths are different.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce dispositif:

  • Fig.1 est une vue en perspective d'une cuvette de WC et de sa chasse-d'eau;
  • Fig. 2 est une vue en perspective éclatée du boîtier;
  • Fig. 3 et 4 en sont deux vues, respectivement, en coupe longitudinale et en coupe transversale passant par l'alvéole contenant la masse active;
  • Fig. 5 à 7 sont trois vues en coupe longitudinale par un plan parallèle au fond de ce boîtier disposé à l'intérieur du réservoir d'une chasse-d'eau, respectivement la chasse-d'eau étant remplie, la chasse-d'eau étant en cours de vidange et la chasse-d'eau étant en fin de vidange.
In any case, the invention will be clearly understood with the aid of the description which follows with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, an embodiment of this device:
  • Fig.1 is a perspective view of a toilet bowl and its flush;
  • Fig. 2 is an exploded perspective view of the housing;
  • Fig. 3 and 4 are two views thereof, respectively, in longitudinal section and in cross section passing through the cell containing the active mass;
  • Fig. 5 to 7 are three views in longitudinal section through a plane parallel to the bottom of this housing arranged inside the tank of a flushing device, respectively the flushing device being filled, the flushing device being drained and the toilet flushing being finished draining.

Le dispositif selon l'invention comprend un boîtier (2) qui, contenant un produit, tel que désinfectant, détergent, désodorisant et/ou colorant, est destiné à être placé dans le réservoir de chasse-d'eau (3) associé à la cuvette d'un WC.The device according to the invention comprises a housing (2) which, containing a product, such as disinfectant, detergent, deodorant and / or dye, is intended to be placed in the flush tank (3) associated with the toilet bowl.

Le boîtier (2), représenté plus en détail à la figure 2, comprend un fond (5) qui, obtenu de préférence par thermoformage, délimite trois alvéoles. Ce fond, de forme parallélépipèdique, est destiné à être placé verticalement dans la chasse-d'eau, dans le sens de sa longueur. La première alvéole (6) s'étend sur toute la longueur du fond, et communique avec l'extérieur par deux ouvertures constituées par des évidements ménagés dans la paroi inférieure pour celui (7) et dans la paroi supérieure pour celui (8). Une deuxième alvéole (9) s'étend à partir de la paroi supérieure du boîtier sur une partie de la hauteur de celui-ci.The housing (2), shown in more detail in FIG. 2, comprises a bottom (5) which, preferably obtained by thermoforming, delimits three cells. This bottom, of rectangular shape, is intended to be placed vertically in the flush, in the direction of its length. The first cell (6) extends over the entire length of the bottom, and communicates with the outside through two openings formed by recesses in the lower wall for the one (7) and in the upper wall for the one (8). A second cell (9) extends from the upper wall of the housing over a part of the height thereof.

Cette alvéole est constituée d'une partie (9a) de profondeur importante et d'une partie (9b) moins profonde, séparées par une cloison (11) présentant des ouvertures (11 a) et (11b) à ses extrémités. La partie (9b) de l'alvéole (9) communique avec l'alvéole (6) par l'intermédiaire de deux ouvertures délimitées par deux évidements (10) débouchant dans la paroi séparant l'alvéole (6) de la partie (9b) de l'alvéole (9). La partie (9a) de l'alvéole (9) est destinée à contenir la masse active d'un produit devant être distribué en fin de vidange du réservoir, cette masse pouvant y être coulée à l'état fluide, le boîtier étant disposé à plat sous l'orifice de remplissage, sans qu'on ait à craindre l'obstruction des orifices (10) du fait de la profondeur supérieure de cette partie (9a).This cell consists of a portion (9a) of significant depth and a portion (9b) shallower, separated by a partition (11) having openings (11a) and (11b) at its ends. The part (9b) of the cell (9) communicates with the cell (6) by means of two openings delimited by two recesses (10) opening into the wall separating the cell (6) from the part (9b ) of the socket (9). The part (9a) of the cell (9) is intended to contain the active mass of a product to be dispensed at the end of the emptying of the reservoir, this mass being able to be poured therein in the fluid state, the housing being arranged at flat under the filling orifice, without having to fear the obstruction of the orifices (10) due to the upper depth of this part (9a).

En dessous de l'alvéole (9) est avantageusement prévue une alvéole (12) qui communiquant avec l'extérieur par des ouvertures constituées par des évidements (13) débouchant dans la paroi limitant l'alvéole avec l'extérieur, ou dans la partie du couvercle qui ferme celle-ci, contient un autre produit, tel qu'un colorant, un désodorisant ou un désinfectant destiné à se dissoudre dans la totalité de la masse d'eau contenue dans le réservoir.Below the cell (9) is advantageously provided a cell (12) which communicates with the outside by openings constituted by recesses (13) opening into the wall limiting the cell with the outside, or in the part of the cover which closes the latter, contains another product, such as a dye, a deodorant or a disinfectant intended to dissolve in the entire body of water contained in the tank.

D'un point de vue pratique, le fond (5) du boîtier (2) étant placé à l'horizontale, il est procédé au remplissage des alvéoles (9) et (12) par simple coulée des produits à l'état liquide ou à l'état pâteux dans celles-ci sans qu'il soit nécessaire de procéder à un pastillage. Après durcissement des produits dans les alvéoles (9) et (12), un couvercle (14) est fixé sur le fond (5) par tout procédé approprié.From a practical point of view, the bottom (5) of the housing (2) being placed horizontally, the cells (9) and (12) are filled by simple pouring of the products in the liquid state or in the pasty state in them without the need for pelletizing. After the products have hardened in the cells (9) and (12), a cover (14) is fixed to the bottom (5) by any suitable method.

La disposition du boîtier ainsi décrite ne fait pas obstacle à l'utilisation d'une masse active introduite sous forme solide plutôt que fluide, ce qui pourrait par exemple permettre d'utiliser un stock existant de produit solide préformé.The arrangement of the housing thus described does not preclude the use of an active mass introduced in solid rather than fluid form, which could for example allow the use of an existing stock of preformed solid product.

Comme montré notamment aux figures 5 à 7, la hauteur (h) égale à la différence entre les hauteurs, respectivement (ha) de l'alvéole (6) et (hb) de l'alvéole (9), doit satisfaire à la condition

Figure imgb0001
As shown in particular in FIGS. 5 to 7, the height (h) equal to the difference between the heights, respectively (ha) of the cell (6) and (hb) of the cell (9), must satisfy the condition
Figure imgb0001

Comme montré à la figure 5, lorsque la chasse-d'eau est en position remplie, une bulle d'air (15) est ménagée dans la partie supérieure de l'alvéole (9). Le volume de la bulle d'air est compris entre 0,3 et 0,95 fois le volume de l'alvéole (9).As shown in Figure 5, when the flush is in the filled position, an air bubble (15) is formed in the upper part of the cell (9). The volume of the air bubble is between 0.3 and 0.95 times the volume of the cell (9).

Selon une autre caractéristique, le volume de la chambre (6) est supérieur à la moitié de la différence entre le volume de la seconde alvéole (9) et celui de la bulle (15).According to another characteristic, the volume of the chamber (6) is greater than half the difference between the volume of the second cell (9) and that of the bubble (15).

Les figures 5 à 7 montrent ce dispositif lors de trois phases d'utilisation. Dans la forme d'exécution représentée, le produit actif logé dans l'alvéole (9) se présente sous forme d'une masse solidifiée (16) qui repose, si on le souhaite, sur des plots (17) ménagés à la partie inférieure de l'alvéole. De par l'érosion due à la dissolution d'une certaine quantité de produit, la masse (16) a déjà subi un certain glissement vers le bas.Figures 5 to 7 show this device during three phases of use. In the embodiment shown, the active product housed in the cell (9) is in the form of a solidified mass (16) which rests, if desired, on pads (17) formed at the bottom of the socket. Due to the erosion due to the dissolution of a certain quantity of product, the mass (16) has already undergone a certain sliding downwards.

L'alvéole (12) contient, pour sa part, une certaine masse solide (18) d'un produit désodorisant, colorant ou désinfectant l'eau, qui se dissout directement dans la masse d'eau du réservoir.The alveolus (12) contains, for its part, a certain solid mass (18) of a deodorizing, coloring or disinfecting water product, which dissolves directly in the mass of water in the tank.

La figure 5 représente le boîtier lorsque le réservoir de chasse-d'eau est plein. Comme montré au dessin, l'alvéole (9) contient une certaine quantité d'eau dans laquelle va se dissoudre la masse active (16), surmontée d'un certain volume d'air (15). Lors de la vidange du réservoir de chasse-d'eau, le volume de solution concentrée contenu dans l'alvéole (9) demeurera dans celle-ci tant que le niveau d'eau n'atteindra pas son niveau dans l'alvéole (6), comme montré à la figure 6. Lors de la poursuite de la vidange du réservoir, l'eau va s'évacuer de l'alvéole (6), et entraîner avec elle le volume de solution concentrée que contient l'alvéole (9).Figure 5 shows the housing when the flush tank is full. As shown in the drawing, the cell (9) contains a certain amount of water in which the active mass (16) will dissolve, surmounted by a certain volume of air (15). When emptying the flush tank, the volume of concentrated solution contained in the cell (9) will remain in the latter until the water level reaches its level in the cell (6 ), as shown in Figure 6. When the tank continues to be emptied, the water will drain from the cell (6), and carry with it the volume of concentrated solution contained in the cell (9 ).

Il ressort de cet agencement que la solution concentrée en produit actif ne se diluera que dans les derniers litres d'eau du réservoir, c'est-à-dire ceux formant le volume résiduel demeurant dans le fond de la cuvette des WC.It appears from this arrangement that the solution concentrated in active product will only be diluted in the last liters of water from the tank, that is to say those forming the residual volume remaining in the bottom of the toilet bowl.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un boîtier destiné à contenir des produits désinfectants, détergents, désodorisants, colorants, etc... pour nettoyage de cuvettes de WC, d'un fonctionnement très efficace et d'une conception très simple puisque les différents produits mis en jeu peuvent être coulés directement dans le boîtier sous forme fluide, sans nécessiter un pastillage préalable, comme tel est le cas habituellement, et dont la position du boîtier dans le réservoir n'a pas à être repérée avec précision. Ce dispositif est également très performant puisqu'il agit tout aussi efficacement après un arrêt prolongé de la chasse-d'eau, que lors d'une vidange de celle-ci suivant immédiatement son remplissage.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a box intended to contain disinfectants, detergents, deodorants, dyes, etc. for cleaning toilet bowls, a very efficient operation and very simple design since the various products involved can be poured directly into the housing in fluid form, without requiring prior tabletting, as is usually the case, and the position of the housing in the tank does not have to be pinpointed. This device is also very efficient since it acts just as effectively after a prolonged stop of the flush, as during an emptying thereof immediately following its filling.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif, décrite ci-dessus à titre d'exemple; elle en embrasse, au contraire, toutes les variantes de réalisation.It goes without saying that the invention is not limited to the sole embodiment of this device, described above by way of example; on the contrary, it embraces all of its variant embodiments.

C'est ainsi notamment que ce boîtier pourrait ne pas posséder d'alvéole (12) contenant un second produit actif, que l'alvéole (12) pourrait contenir un ou des éléments formant lest et assurant un parfait positionnement du boîtier à la verticale, ou que les profondeurs respectives des différentes alvéoles pourraient être différentes les unes des autres, sans que l'on sorte pour autant du cadre de l'invention.Thus, in particular, this box could not have a cell (12) containing a second active product, and the cell (12) could contain one or more ballast-forming elements and ensuring perfect positioning of the box vertically, or that the respective depths of the different cells could be different from each other, without departing from the scope of the invention.

En outre, il serait possible de fabriquer un boîtier constitué de l'assemblage de deux dispositifs selon la présente invention, de capacités identiques ou différentes, l'avantage d'un tel système étant de pouvoir libérer, au même moment ou à des moments différents de la vidange du réservoir de la chasse-d'eau, plusieurs solutions concentrées de produits actifs, différents en quantités égales ou différentes.In addition, it would be possible to manufacture a housing consisting of the assembly of two devices according to the present invention, of identical or different capacities, the advantage of such a system being being able to release, at the same time or at different times emptying the flush tank, several concentrated solutions of active products, different in equal or different quantities.
