Description

MAINTENANCE PRODUCT DISTRIBUTOR FOR TOILET BOWLS

The present invention relates to a dispenser for cleaning products for toilet bowls, and more specifically to a dispenser for cleaning and / or perfuming for toilets. Various solutions have been proposed to distribute in the toilet bowls cleaning and / or perfuming products. Thus, are sold blocks intended to be arranged in flushing water. The blocks melt slowly and diffuse a cleaning product. Such a product can satisfy in terms of cleaning, but it does not allow to diffuse a perfume. It is also known to hang on the edge of the toilet a cage, containing a block of product that is washed by the water flowing from the flush when it is actuated. Such a block of product, which is in the open air, can have no scenting effect throughout its life. In both cases, the problem stems from the fact that perfuming products are volatile, and lose their perfuming effect when exposed to the air and that the quantity of product they release at each hunt decreases at as the block decreases in volume. US-A-3 946 448 (El Sioufy) describes a device for disinfection and chemical purification for toilet bowls. The device is fixed on the inner rim of the bowl; it comprises a tank filled with disinfection and purification product. The tank is closed in its lower part by a plug, biased upwards by a spring located in the tank. This device essentially has the disadvantage of being made up of a large number of articulated parts, which makes it cost prohibitive.

EP-A-0 538 957 (Sara Lee) discloses a cleaning and purification device which, like the previous one, hangs on the rim of the toilet bowl. The device comprises a reservoir, filled with a cleaning and purification liquid, which is in constant communication with a porous mass in the flow path of the water from the flush. To ensure constant communication, this document proposes to use a foam introduced into the neck of the tank. When flushing the water, the water flows and causes some of the product that soaks the porous mass. The chemical purification effect is obtained by the evaporation of the product impregnating the porous mass, between the flushing of water. This device has the disadvantage that the tank is empty sometimes, even when the toilet is not used. More precisely, the flow is not systematically continuous; the flow stops when the plate is saturated, depending on the viscosity, temperature, and frequency of the flushes. The R: 131900A31982 NICI31982--100914-d of patent filed td.doc 1/16 15/09/2010 4:15 operation of the device is irregular, and the service life can vary from single to double. In addition, it is provided in this document to be able to recharge the reservoir with cleaning liquid. To do this, the tank must be detached from a foam support and then returned to access the opening of the tank. This charging process is unhygienic, so that in practice it is never implemented. On the contrary, the device is generally replaced in its entirety. This implies a significant consumption of plastic and recycling problems that result.

EP-A-0 785 315 (Sara Lee) proposes another device of the same kind. This device proposes to provide in the neck of the reservoir a liquid passage, opening against the porous mass; the liquid passage is provided with an air inlet opening. The viscosity of the product and the size of the passages and openings are determined such that the pressure of the liquid on the porous mass is constant and is independent of the level of liquid in the reservoir. This device provides a complex solution to the problem of the variation of the product flow depending on the level in the tank, but still has the same drawbacks, namely that the tank empties, even when the toilet is not used, and that the operation of the device is irregular.

Another similar device marketed by La Johnson Française proposes to use, in place of a porous mass, a grooved plate. In this case, as in the case of the porous mass, there is the problem of the upwellings in the tank by osmosis because of the direct contact between the water of the flush absorbed by the porous mass or captured by the grooved plate and the liquid contained in the tank.

The problem of product flow between two hunts also arises. It is also known from WO 96/38 637 (Henkel KG) a device for dispensing cleaning liquid into the toilet bowl. This device comprises a reservoir adapted to be disposed under the rim of the toilet bowl to be rinsed by the flushing liquid. The tank has at least one inlet and one outlet for the flushing liquid. The device also includes a catch hook of the tank at the edge of the toilet bowl. The reservoir is partially filled with a gel, so that the flushing liquid entering the reservoir takes up a quantity of gel before being discharged into the toilet bowl.

EP-A-1,287,211 of the Applicant proposes a product dispensing device for toilet bowl clinging to the rim of the bowl. The cleaning product is contained in a tank in communication with a tube. The tube has the R: 131900A31982 NICI31982--100914-dde patent tq filed.doc 2/16 15/09/2010 4:15 minus an opening of a size preventing the flow of liquid in the absence of hunting of 'water. During a flush, the flow of water in the vicinity of the tube or along it causes a depression by hydrodynamic effect, and ensures the suction of the liquid out of the dispenser.

EP-A-1,878,168 of the Applicant discloses a product dispensing device for a toilet bowl comprising at least two compartments. Each compartment is, via its lower part, connected with a free opening of a size which prevents the flow of the maintenance liquid out of said compartment in the absence of flushing. The openings of the compartments open at one end of a tube, the other end of the tube being open. The dispensers described above have product reservoirs and more or less complex devices for distributing the product in the flushing water. The presence of one or more tanks imposes a relatively large size of the dispenser, the tank or tanks can not be retracted under the rim of the bowl. In addition, the flow of the cleaning product in the flushing water is not always regular because dependent on the air inlet into the tank. Finally, the refilling of active liquid tanks is not usually expected which implies that the distributor must be completely renewed, once the tank emptied. When, however, it is expected to be able to recharge the tank, the charging process is complex and unhygienic. There is therefore a need for a dispensing device for cleaning and / or perfuming product in toilet bowls that is simplified and of reduced size. In addition, there is a need for a toilet cleaning dispenser device that is easily and hygienically refillable.

For this purpose, the invention proposes to ensure a regular distribution of product in the flush water by means of an absorbent mass impregnated with product by a dispensing tube. The dispensing tube allows to soak the absorbent mass initially or when it has been washed with any cleaning product. No tank is to change, the amount of packaging used is greatly reduced. The absence of tank also allows a more compact and almost retractable arrangement under the rim of the bowl. The aesthetic is thus improved. The use of a simplified and more aesthetic system also allows for a cage longer and more ergonomic compared to the edge of the bowl partly hidden by the rim and the underside of the water inlet during actuation hunting. In addition, because of the use of the dispensing tube, it is easy to recharge the absorbent mass with the maintenance liquid. This refill is performed without having to touch the dispensing device. The refill is therefore more hygienic than the refilling of the dispensing devices of the prior art. The invention more particularly proposes a dispenser for cleaning products for toilet bowls, comprising: a support provided with means for hooking to the bowl; - At least one absorbent mass disposed in the water path of the flush when the dispenser is hooked on the bowl; - At least one product distribution tube having: - a filling opening; at least one dispensing opening adapted to deliver the product to the absorbent mass, said dispensing opening being distinct from the filling opening. According to preferred embodiments, the dispenser according to the invention comprises one or more of the following characteristics, taken alone or in combination: the absorbent mass has an absorption capacity of between one and eight times its dry weight; the absorbent mass has dimensions such that it has an absorption capacity of 30 to 60 ml of maintenance product; - The dispensing tube is secured to the support; - The dispensing tube extends longitudinally above the absorbent mass when the dispenser is hooked on a bowl; - The dispensing tube has a plurality of dispensing openings opening on the absorbent mass; - The dispensing tube has a distribution slot opening on the absorbent mass; - The dispenser further comprises a feed tube extending in a direction substantially parallel to the attachment means of the support and having an upper opening and a lower opening opening on the filling opening of the dispensing tube; the upper opening of the feed tube is free; the filling opening of the dispensing tube is free; - The supply tube is coupled to the distribution tube; and - the feed tube has a section in the form of a semicircle whose base is supported on the attachment means of the support. The invention also relates to a method of dispensing cleaning product in a toilet bowl, comprising the steps of: R: 131900A31982 NICI31982--100914-dde patent filed td.doc 4/16 15/09 / 2010 4:15 - Attach to the toilet bowl a maintenance product dispenser as described above in all its combinations; - filling the dispensing tube with product; - Spread the maintenance product from the dispensing tube in the absorbent mass; - on each flush, dilute some of the maintenance product contained in the absorbent mass in the flushing water. According to preferred embodiments, the method according to the invention comprises one or more of the following characteristics taken alone or in combination: the method further comprises a step of reloading the dispensing tube with cleaning product without dropping out of toilet product dispenser for the toilet bowl; and the recharging step is carried out after 50 to 150 hunts. Other characteristics and advantages of the invention will appear on reading the following description of a preferred embodiment of the invention, given by way of example and with reference to the appended drawings in which: FIG. 1 shows in section a diagram of a maintenance product dispenser according to a first example; - Figure 2 shows a front view of the components of the dispenser of Figure 1; FIG. 3 represents an exemplary support that can be implemented in the distributor of FIG. 1; FIG. 4 is a perspective view of a second example of a maintenance product dispenser according to a first example; and FIG. 5 is a sectional view of a third example of a maintenance product dispenser. As shown in Figure 1, a distributor 10 of toilet bowl care product, comprises a support 12 secured to means 14 for attachment to the bowl. The attachment means to the bowl are here made in the form of a rod (or tab) 15 terminated by a hook 16 adapted to be hooked on the rim of the toilet bowl. The dispenser 10 is advantageously used to dispense a product which is a liquid. The product may include surfactants, fragrance essences, emulsifiers, limescale removers or sequestering agents, disinfectants or dyes. The active components of the liquid may have, separately or jointly, properties: - cleaning, R: 131900A31982 NICI31982--100914-dde patent filed tq.doc 5/16 15/09/2010 4:15 - disinfectants, - descalers, - deodorants, - perfumes, etc.

The support 12 is adapted to receive an absorbent mass 18 so that the absorbent mass 18 is disposed in the path of the flush water when the dispenser 10 is suspended in the toilet bowl. In this case, the support 12 forms a recessed housing into which the absorbent mass 18 is inserted.

This housing is closed on the face intended to be oriented towards the top of the toilet bowl by a grid 20. This grid 20: - prevents direct access to the absorbent mass 18 and the product it contains, including a infant, - leaves the absorbent mass 18 in contact with the ambient air, so that a greater amount of maintenance product contained in this absorbent mass can evaporate and ensure a deodorizing and / or fragrant effect - allows the flushing liquid to rinse the absorbent mass 18 with each flush, so that the flushing water is loaded with cleaning product before being discharged into the toilet bowl, and - retains the absorbent mass in the receiving housing provided for this purpose in the support, during hunting, especially when the flushing liquid passes through the support 12. Other means of maintaining the absorbent mass in place during the flush can be provided in an additional manner or alternative to the grid. For example, the housing may have a lower bowl-shaped surface such that the absorbent mass is received in the depression of the bowl. In addition, according to a preferred variant, the grid is arranged above the dispensing tube, this to prevent any access to the product by a young child Furthermore, the support 12 has a plurality of discharge openings 22, intended to allow the passage of the flushing liquid after it has passed through the absorbent mass 18 and is thus loaded with maintenance product. These discharge openings 22 are formed in FIG. 1 on the lower face of the support 12, that is to say its face intended to be oriented towards the bottom of the toilet bowl when the dispensing device 10 is suspended in the toilet bowl. As shown in Figure 1, the support 12 is made integrally with the attachment means 14. However, as shown in Figure 3, R: 131900A31982 NICI31982--100914-dde patent tq filed. doc 6/16 15/09/2010 4:15 the support 12 may be made separately from the attachment means. In this case, the support 12 may have a sleeve 36 forming a housing 38 for receiving the attachment means 14, in particular for receiving the rod 15. The rod 15 may be force-fitted into the housing 38. Advantageously, the rod 15 has ribs for adjusting the attachment height of the support 12 in the toilet bowl. The absorbent mass 18 preferably has a water absorption capacity of between 1 and 8 times its dry weight. The absorbent mass 18 also preferably has dimensions such that it has an absorption capacity of 30 to 60 ml of maintenance product, this amount of maintenance product corresponding to 4 weeks of normal use of the products. bathroom. The absorbent mass may be composed of one or more layers of different density and absorption. The absorbent mass may in particular be bleached cellulose, cellulose, melamine resin foam or polyvinyl acetate (PVA). The absorbent mass can be chemically treated to further enhance its absorption capabilities. The dispensing device 10 further comprises a tube 24 for dispensing the cleaning product. The dispensing tube may be made integrally with the attachment means or separately. In the latter case, the dispensing tube may be attached to the attachment means, in particular the rod 15, by clipping, gluing or any other method known to those skilled in the art. This distribution tube 24 has a filling opening 26 and at least one dispensing opening 28, distinct from the filling opening 26.

The filling opening 26 allows in particular the filling of the distribution tube 24 with a cleaning product for the toilet bowl. The dispensing opening 28 makes it possible to distribute this maintenance product in the absorbent mass 18. To do this, the dispensing opening 28 may take the form of a distribution slot extending in a plane perpendicular to the plane This slot opens on the absorbent mass 18. The slot may for example extend over the entire length of the dispensing tube 24 or on a central portion, only, of the dispensing tube 24. The slot of FIG. distribution may have a width between 0.2 and 5 mm thick. Alternatively, and as shown in Figure 2, the dispensing tube 24 may include a plurality of dispensing openings distributed along the length of the dispensing tube 24 and opening on the absorbent mass. In this case, the distribution tube 24 has between 1 and 8 dispensing openings, the diameter of which is R: 131900A31982 NICI31982--100914-dde of patent filed tq.doc 7/16 15/09/2010 4:15 between 1 and 3 mm. Such a diameter prevents the maintenance product from drying in the openings and thus prevents the smooth flow of the care product to the absorbent mass. The openings are preferably equi-distributed along the length (i.e., on a dimension measured parallel to the plane of the upper surface of the absorbent mass) of the dispensing tube. The slot or the dispensing openings make it possible to ensure a homogeneous distribution of the maintenance liquid throughout the volume of the sponge and thus to increase the efficiency of the dispenser for given dimensions, since the absorbent mass is thus imbibed with a larger amount of maintenance fluid. The use of a distribution tube makes it possible to imbibe more homogeneously the absorbent mass, especially when it is of considerable length relative to its width. Indeed, the absorbent mass may especially have a length of between 12 and 20 cm, a width of between 2.5 and 5 cm and a thickness of between 1 and 3 cm, in order to increase the volume of flushing liquid the absorbent mass impregnated with maintenance product. It should be noted that the absorbent mass can be achieved by means of one, two or more separate unit absorbent masses. The absorbent mass, because of its great length and its small width, can be concealed, at least partially, under the rim of the toilet bowl to improve the aesthetic appearance of the dispenser of cleaning product, reducing , especially the size of the dispenser in the visible part of the toilet bowl compared to a conventional dispenser. The dispensing device 10 also comprises, as illustrated in Figure 1, a feed tube 30 extending in a direction substantially parallel to the means 14 of attachment of the support. The feed tube 30 has an upper opening 32 and a lower opening opening on the filling opening 26 of the dispensing tube 24. The upper opening of the feed tube 32 is free or closed by a grid or by a valve , to allow the introduction of maintenance product into this feed tube. The upper opening 32 has a diameter of between 6 and 10 mm. This makes it possible to introduce a conventional tip of a cleaning product bottle, intended to guide the cleaning product when it is poured. The feed tube 30 is coupled to the dispensing tube 24 so that all the maintenance fluid which is poured into the feed tube 30, via the upper opening 32, passes into the dispensing tube 24, at the same time. inside which it is distributed before being evacuated, at least partially, through the different distribution openings. The supply tube can be made integrally with the dispensing tube, or separately. The supply and distribution tubes can be fixed to one another by gluing, clipping or any other method known to those skilled in the art. As is more clearly seen in FIG. 2, the feed tube 30 preferably has a semicircular section whose base is supported on the hooking means of the support 14 to limit the bulk of the tube. In the present case, a groove 34 is hollowed out in the planar base of the feed tube 30, which groove is complementary to the rod 15. A connection of the dovetail type is thus produced between the tube of supply 30 and the rod 15 of the hooking means of the support 14. FIG. 4 shows a second example of a maintenance product dispenser 100. The dispenser 100 differs from the dispenser 10 according to the first example in that the support 12 receives two absorbent masses 181, 182. The two absorbent masses are each received in a separate housing, the two housings being separated by a wall 40. Removable grids, not shown, can each close one of two housings, on the upper face when the dispenser 100 is hooked to the toilet bowl. These grids: - prevent direct access to the absorbent masses, especially by a toddler, - leave the absorbent masses in contact with the ambient air, so that a greater amount of maintenance product contained in these masses absorbent evaporates and provides a deodorant and / or scenting effect, - allow the flushing liquid to rinse the absorbent masses with each flush, so that the flushing water is loaded with each of the cleaning products before be drained into the toilet bowl while keeping the absorbent masses in place during the hunt. Preferably these grids are located above the dispenser tube 24 to prevent direct access to the care product, especially by a toddler. Each housing here has a bowl shape such that the absorbent mass 181, 182 is at least partially received in the recessed volume of the bowl. Here, each of the absorbent masses is totally received in the recessed volume of the cuvette, that is to say that the upper surface of each absorbent mass, R: 131900A31982 NICI31982--100914-dde patent tq filed.doc 9 Opposite the surface resting on the bottom of the housing, is at the same level as the rim of the bowl formed by the housing. To allow the evacuation of the flushing liquid loaded with the maintenance product, the support 12 comprises evacuation openings 221, 222. Unlike the first dispenser example of FIG. 1, the evacuation openings 221, 222 are not not here performed on the bottom face of the support 12. On the contrary, the discharge openings 221, 222 are here made on a lateral surface of the support 12. More precisely, here, the discharge openings 221, 222 are performed at the rim of the bowl formed by the housing of the support 12, to allow the evacuation of liquid overflowing from this bowl. In other words, the bottom wall of the discharge openings 221, 222 is substantially at the same level as the rim of the bowl formed by the housing of the support 12. The dispenser 100 further comprises a distribution tube 24, of the type of that described in the first example, and a feed tube 30, similar to the feed tube 30 of the first embodiment. The operation of the dispenser 100 according to the second example is as follows. In case of hunting, the flushing liquid is guided towards the absorbent masses received in the hollow volumes of the bowls formed by the housing of the support 12. When the volume of flushing liquid exceeds the hollow volume of the bowl, the overflow flushing liquid, loaded with cleaning product thanks to the soaked absorbent mass, is discharged through the discharge orifices 221, 222. Such a mode of operation allows in particular to avoid run-off of maintenance product between two hunts . Figure 5 shows a third example of a dispenser 200 maintenance product. This dispenser 200 is particularly suitable for dispensing two incompatible cleaning products in the toilet bowl. Incompatible products are products which react with each other when they are brought into contact. The two incompatible products may have different actions, for example a deodorant or scenting product and a cleaner or descaler.

The identical elements or function identical to the elements of the first and second examples of Figures 1 and 4 bear, in Figure 5, the same reference number. These identical elements or identical function are not described in more detail here for the sake of brevity of the present description. The dispenser 200 differs from the dispenser 10 according to the first example in that the support 12 receives two absorbent masses 181, 182. The two absorbent masses are preferably each received in a separate housing, the two housings being separated by a wall 40. Removable grids 201, 202 close R: 131900A31982 NICI31982--100914-d of patent filed tq.doc 10/16 15/09/2010 4:15 each one of two housings, preferably on the upper face when the distributor 200 is hanging on the toilet bowl. These grids: - prevent direct access to the absorbent masses, especially by a toddler, - leave the absorbent masses in contact with the ambient air, so that a greater amount of maintenance product contained in these masses absorbent evaporates and provides a deodorant and / or scenting effect, - allow the flushing liquid to rinse the absorbent masses with each flush, so that the flushing water is loaded with each of the cleaning products before be drained into the toilet bowl while keeping the absorbent masses in place during the hunt. The grids are preferably located above the dispensing tube to prevent access to the cleaning product, especially by a toddler. Other means of maintaining the absorbent masses in place during the flush may be provided additionally or alternatively to the grid. In particular, the housings can be of the form described in the case of the second example of the dispenser of FIG. 4. The operating mode of the dispenser 200 is then identical to the operating mode of the dispenser 100. To allow the evacuation of the loaded flushing liquid in maintenance product, the support 12 comprises discharge openings 221, 222. The distributor 200 further comprises two distribution tubes 241, 242. Each of these two distribution tubes 241, 242 is of the type described in FIG. frame of the first embodiment. Each distribution tube 241, 242 is associated with a clean absorbent mass, to avoid any risk of mixing incompatible products. To each delivery tube 241, 242 may be associated a feed tube 301, 302. Each feed tube may be similar to the feed tube 30 of the first embodiment. The dispensers as described above allow to implement a method of dispensing cleaning product in a toilet bowl, comprising the steps of: - hooking to the toilet bowl the dispenser maintenance product; - filling the product or distribution tubes with product; - Spread the maintenance product from the distribution tube or tubes in the absorbent masses or masses; A: 131900A31982 NICI31982--100914 -d of patent tq filed.doc 11/16 15/09/2010 4:15 - on each flush, dilute some of the cleaning product contained in the absorbent mass (s) in the water of hunting. In addition, this method may comprise a step of reloading the distribution tube (s) with cleaning product without disconnecting the device from the toilet bowl. The recharging step can in particular be carried out after 50 to 150 hunts. Alternatively, the dispensing device may be devoid of dispensing tube. In this case, the absorbing mass or masses are recharged directly in the absence of a distribution tube.

In addition, according to another variant, the support and the attachment means may be shaped to allow the positioning of the support 12, as well as the dispenser tube under the rim of the toilet bowl. This embodiment is particularly aesthetic since only the rod 15 of the attachment means remains directly visible in the toilet bowl.

Of course, the present invention is not limited to the examples and to the embodiment described and shown, but it is capable of numerous variants accessible to those skilled in the art. A: 131900A31982 NICI31982--100914-d of patent filed td.doc 12/16 15/09/2010 4:15
