Description

[0001] The present invention relates to a toilet basket for receiving a solid water soluble active-ingredient preparation in the form of a water soluble block and comprising a clean water tank for sweeping the flow of active water.

[0002] Several solutions exist for cleaning and/or disinfecting and/or deodorizing sanitary elements, especially toilets. A first solution consists in self-adhesive detergent compositions which can be applied directly to the wall of a sanitary element in a block placed in cage. A second solution consist of a dispenser device hanged on the toilet bowl.

[0003] Such a dispenser be formed of a body adapted to be suspended in a toilet bowl and comprising a holding means for holding a reservoir for an active-ingredient preparation. The active-ingredient preparation may for example be incorporated into a water soluble block, forming the active ingredient reservoir. Such a water soluble block are able to be used in one of the simplest embodiments of the dispenser devices, in which the holding means are formed by hook, stem, pin or tab. These embodiments are notably simple in terms of manufacturing. The body of the dispenser being usually formed of injected plastic, the body of these simple embodiments may be formed in one piece. These simple dispensers are known under the name of cage less toilet bowl dispenser and are notably described in EP 2 191 077, US 3 947 901 or WO 2011/141720.

[0004] However these simple embodiments of toilet bowl dispenser device provides poor control on the amount of active ingredient released in the toilet bowl with each flow of a flushing water. After a number of use, the block may be sufficiently dissolved to not be held anymore by the hook, stem, pin or tab. The remaining block then partly or totally falls in the toilet bowl. The block partly falling in pieces disturb the control of the amount of active ingredient released in the toilet bowl

[0005] More complex geometries of dispenser may solve partially this issue with a form of basket placed at the inner sidewall of a toilet bowl, as notably described in FR 1 602 063. The basket or cage is holding the block in place for a greater number of uses than the above-mentioned cage less device. However this basket or cage devices are a little more complex considering their manufacturing process. The cage may be formed in one piece, with notably molded hinges are present so as to close the cage on the inside-held block. The presence of these hinges imposes a more complex manufacturing process.

[0006] Besides for both embodiment types, with or without the cage, after each flush, when the flow of flushing water had stopped, there is an "after-dripping" of the block, i.e., drops of flushing water continue for a prolonged period of time, depending on the erodibility of the block to flow down the sidewall of the toilet bowl. The concentration of colorant in these drops increases with time, thus producing on the sidewall a stripe of color, e.g. of blue, which extends from the block container downwardly causing an unclean, unesthetic aspect of the bowl. This stripe is the more difficult to remove, the longer the "after-dripping" has lasted.

[0007] In view of this "after-dripping" effect, siphons have been introduced in the cage embodiment. US 2016/0032576 for examples discloses the use of such siphon. However, because of the tortuosity of the siphon, cages incorporating siphon are difficult to manufacture.

[0008] Accordingly there is still a need to provide a dispensing mechanism in the toilet bowl having a control on the amount of active-ingredient released without suffering from the above-described drawbacks of complex manufacturing process and of staining the internal sidewall of the toilet bowl with colored active ingredient.

[0009] According to the present invention, there is provided a toilet basket for receiving a solid water soluble active-ingredient preparation in the form of a water soluble block, the water soluble block dissolving with flushing water of the toilet into active water, the basket comprising :

[0014] Figure 1 shows a proposed embodiment for a toilet basket. Notably, as shown, the proposed toilet basket 20 comprises at least a first container 22. In the particular embodiment of Figure 1, the proposed toilet basket 20, also comprise two additional containers 24 and 26. Each of these two additional containers 24 and 26 is positioned at side of the first container 22. The first container 22 is consequently the container in the middle. These additional container 24 and 26 are optional and will only be described later on this document. Figure 1 also shows that the proposed toilet basket 20 may also comprise a hanging hole 28 for engaging a retainer (not shown) to the edge of a toilet bowl. This engaging retainer may be clipped when engaging the hanging hole 28. Alternatively, the hanging hole 28 may be replaced by an integral retainer (not shown) for fastening to the edge of the toilet. Accordingly, the retainer may be made in one piece with the first container 22. Optionally the retainer may be hinged to the basket 20, notably to the first container 22.

[0015] Back to Figure 2, the opened container 22 has a chamber 48 corresponding to an interior volume of the container 22. The chamber 48 is housing water soluble block 40 held inside the container 22. This water soluble block 40 is a solid water soluble active-ingredient preparation in the form of a block. Accordingly the proposed toilet basket 20 is said for receiving a solid water soluble active-ingredient preparation in the form of a water soluble block. The water soluble block 40 is designed to dissolve with flushing water of the toilet. The flushing water is the water provided in the toilet bowl so to flush this toilet bowl. While dissolving, the water soluble block material is forming active water. In other words, the active water is composed of the flushing water incorporating the active ingredient released by the dissolving water soluble block 40.

[0016] To allow the dissolution of the water soluble block 40 into active water, the container 22 has a flushing water opening 46. Notably in the embodiment shown in Figure 2 and 3, two flushing water openings 46 are provided. Once the water soluble block 40 has been, partly, dissolved into active water, the active water is flowing below the water soluble block 40.

[0017] To allow the emptying of the formed active water therein, the container 22 has an active water outlet 44. Notably in the embodiment shown in Figure 2, two active water outlets 44 are provided. Accordingly once, the water soluble block 40 has been, partly, dissolved into active water, the active water is flowing below the water soluble block 40 and is forming an active water outlet flow out of the container. The active water outlet 44 is emptying at least partially the container 22 from the active water. Indeed, as it will only be described latter in this document, the active water outlet 44, or the assembly of all active water outlet, may not be designed for emptying completely all the active water formed inside the container 22. Accordingly, and notably as shown in Figure 2, the active water outlet 44 may be positioned above the lower inside level of the container 22. Further in reference to Figure 3, it should be noted that the active water outlets 44 differ from the overflow openings 50. These overflow openings 50 are also shown in Figure 1. These overflow openings allow the outflow of the overflow of flushing water inside the container 22. However this overflow is essentially made of flushing water and, even if it may contain part of the dissolved water soluble block, it differs from the active water flow. Indeed the active water flow is collected below the water soluble block 40 before it is emptied by the active water outlets 44. By being collected below the water soluble block 40, the active water provides the accurate composition of active ingredient. On the contrary the overflow is an outflow at the level of water soluble block and thereby the outflow only partially, at best, dissolved the appropriate composition of active ingredient.

[0018] In order to avoid, the water soluble block 40 to dip into stagnant active water inside the container 22, the container 22 may further comprise a support for holding the water soluble block 40 in the chamber 48 above the active water outlet 44. Such a support is e.g. shown in the embodiment of Figure 2, thereby referenced 42 and positioned above the active water outlets 44.

[0019] Figures 3 and 4 shows that the proposed toilet basket comprises a clean water tank 32. This clean water tank 32 is collecting flushing water from the toilet when the toilet bowl is flushed. This collection of water by the tank 32 is made directly during flushing, or is made at least before an active ingredient has been added to the flushing water. Consequently, the water collected in the tank 32 is said to be clean, justifying the expression "clean water tank" 32. As shown in Figure 3, the clean water tank has a tank volume 34 storing the clean water from the collected flushing water. In other words, at least part of the collected flushing water is forming the clean water stored in the tank volume 34. Some other part of the collected flushing water may flow eventually outside of the volume tank because of a possible overflow of the flushing water or because of the turbulences in the flow of flushing water.

[0020] To allow the emptying of the stored clean water active water therein, the clean water tank 32 has also a cleaning outlet 36 as shown in Figures 3 and 4.

[0021] In the proposed toilet basket, the container 22, the cleaning outlet 36 and/or the tank volume 34 are designed to release the clean water into the toilet bowl for sweeping the outlet flow of active water.

[0022] The cleaning outlet 36 and/or the tank volume 34 may notably be designed to maintain a flow of clean water after the toilet flush had stopped. More particularly, the cleaning outlet 36 and/or the tank volume 34 may notably be designed to maintain a flow of clean water after the active water flow had stopped.

[0023] Because clean water is flowing at least partly after the flow the active flow had stopped, the clean water flow is sweeping or cleaning the sidewall of the toilet bowl from any remaining strip of active water, usually coloured. The staining of the internal sidewall of the toilet bowl is thereby avoided.

[0024] Further, the design of the clean water tank 32, notably as shown in Figures 3 and 4, is less tortuous than the design of a siphon. In particular, the active water outlet may be designed not to be a siphon, as for example to be a straight hole. Indeed in a particular embodiment where the container 22 and the clean water tank 32 are integral, it is preferred and possible to realize the container 22 and the clean water tank 32 in one piece. The clean water tank 32 may also be made in one piece with the part of the container that is closed by the closing plate 30, any other equivalent means that close the container(s). The manufacturing process used for making them in one piece may for example be injection moulding.

[0025] Accordingly the manufacturing process of the proposed toilet basket is simpler while proposing a solution to avoid the staining of the internal sidewall of the toilet bowl.

[0026] Either the tank volume 34 or the cleaning outlet 36 or both the tank volume 34 and the cleaning outlet 36 are designed to assure the sweeping of the active water flow.

[0027] The design of the tank volume 34 is for example to be sufficiently big with respect to the volume of active water per flush to assure that clean water is still flowing out of the clean water tank 32 after all the active water has been released in the toilet bowl. For example, the tank volume is of at least 3ml, preferably at least 5ml, more preferably at least 10 ml. Regarding the volume of active water per flush, this volume may correspondingly be less than 1ml, preferably less than 3ml, more preferably less than 5 ml. Alternatively the volume of active water per flush may be less than or equal to 3ml, e.g. of 2 ml.

[0028] The design of the cleaning outlet 36 is for example to be sufficiently small with respect to the cross-section of the active water outlet 44, or of the assembly of all active water outlet, to assure that clean water is still flowing out of the clean water tank 32 after all the active water has been released in the toilet bowl. Consistently this cleaning outlet 36 is shown in Figures 3 and 4 as a small hole. For example, the cleaning outlet 36 has a cross section less than 3 mm², preferably less than 2 mm², more preferably less than 1 mm². Regarding the cross section of the active water outlet 44, or of the assembly of all active water outlet, this cross section may correspondingly be at least of 5 mm², preferably at least of 3 mm², more preferably at least of 2 mm².

[0029] The design of the cleaning outlet 36 and the design of the tank volume 34 may also be correspondingly chosen in order to achieve a controlled gravity flow rate of the clean water flow out of the clean water tank 32. The maximum gravity flow rate notably depends on the cross section of the cleaning outlet 36 and of the height of the tank volume 34. Accordingly to achieve a controlled gravity flow rate for the clean water flow, the cleaning outlet 36 and the volume height of the tank volume 34 are designed correspondingly. For example, this design may result in maximum gravity flow rate out of the clean water tank 32 being two times less than the maximum gravity flow rate of the active water flow. More preferably, this may result in maximum gravity flow rate out of the clean water tank 32 being three or five times less than the maximum gravity flow rate of the active water flow. These differentiated gravity flow rate of the clean water flow and of the active water flow, allows the end of the active flow before the end of the clean water flow. Thereby, the clean water flow may clean or sweep any stripe let by the active water flow.

[0030] Further in the latter-described embodiment where the container 22 is designed to maintain an active water flow after the toilet flush had stopped, the container 22 is also designed respectively to the cleaning outlet 36 and/or the tank volume 34 so that the active water flow stops before the clean water flow stops. Accordingly, the container 22 may also be designed together with the cleaning outlet 36 and/or the tank volume 34.

[0031] As discussed previously in reference to Figures 1 and 2, it is proposed, according to a particular embodiment, that the toilet basket has two additional containers 24 and 26. Similarly, Figures 5 and 6 show another proposed toilet basket 120. This toilet basket 120 present similarities with the toilet basket 20 of Figures 1 to 4. Accordingly, the corresponding features of each of these proposed toilet basket 20 and 120 will be referenced with the same reference signs with the features of the toilet basket 120 having a further "1" before the two other digits of the reference sign. Accordingly, in the proposed embodiment of Figures 5 and 6, two additional containers 124 and 126 are also provided in addition to the first container 122. According to an alternative embodiment (not shown), the proposed toilet basket may comprise only the first container 22, 122 or may comprise only one additional container, 24 or 124.

[0032] As in the embodiment of Figures 5 and 6, the additional container 124, and possibly the further additional container 126, may be positioned at an upper level with respect to the first container. This position at an upper level allows the additional container(s) at the side of the first container 122 to remain clean from the active water flow. Indeed this upper position of the side additional container 124, 126, avoid the side block to get dirty or contaminated by the active water flow.

[0033] This position at an upper level of the additional container(s) 124, 126 is the main difference between the proposed embodiment of Figures 5 and 6 relative to the embodiment of Figures 1 to 4. Indeed, as in the embodiment for Figures 1 to 4, the proposed toilet basket of Figures 5 and 6 also comprise a clean water tank 132, shown in the back perspective view of Figure 7. Figure 8, as top view of the same embodiment, shows more clearly this clean water tank 132 with its tank volume 134 and the cleaning outlet 136.

[0034] The content of this or these additional containers 24, 124, 26, 126 are preferably chosen among the group consisting a bleach block or a perfume bloc. In the preferred embodiments with two additional containers, 24, 124, 26, 126, one additional container is preferably containing a bleach block and the other additional container is preferably containing a perfume block. Relative to the bleach block and to the perfume block, the preferred content for the water soluble block 50 of the first container 22 and 122 discussed above correspond to a blue water block.

[0035] The proposed blue water block is preferably composed according to the following table

Ingredients	Ranges % by weight	Preferred ranges % by weight
Perfume	2 -6	4,0
Anionic surfactant	20 -36	33,3
Hydrotrope	0-10	9,0
Sodium sulfate	40-65	51,5
Antilime scale agent	0,5-1,5	0,5
Colorants	0,01-3	1,5
water	0,1-0,5	0,2

[0036] The proposed bleach block is preferably composed according to the following table

Ingredients	Ranges % by weight	Preferred ranges % by weight
Perfume	2 -6	4,0
Anionic surfactant	20 -36	32,798
Hydrotrope	0-10	9,0
Sodium sulfate	39-63	51,5
Antilime scale agent	0,5-1,5	0,5
Bleaching agent	1-5	2,00
Colorants	0,001-3	0,002
water	0,1-0,5	0,2

[0037] The proposed perfume block is preferably composed according to the following table :

Ingredients	Ranges % by weight	Preferred ranges % by weight
Perfume	2 -6	4,0
Anionic surfactant	20 -36	34,798
Hydrotrope	0-10	9,0
Sodium sulfate	39-63	51,5
Antilime scale agent	0,5-1,5	0,5
Colorants	0,001-3	0,002
water	0,1-0,5	0,2

[0038] Figures 9 and 10 show a variant of to the embodiment of Figure 5. This variant mainly differs from the embodiment of Figure 5 on the active water tank. Accordingly, the corresponding features of these proposed toilet baskets in Figure 5 and in Figures 9 and 10 will be referenced with the same reference signs with the features of the toilet basket of Figures 9 and 10 having a "2" before the two other digits of the reference sign instead of a "1". The active water tank 132 in Figures 7 and 8, is an active tank in one piece with the container 122, or at least with the part of the container closed by the closing plate 130 (shown in figure 6). Alternatively, the active water tank 232 in Figures 9 and 10 is integral with the container 222 but is not made in one piece. The active water tank 232 is a patch attached to the container 222 after the manufacturing, e.g. by injection moulding, of each of these parts. This attachment may notably be provided by clicking.

[0039] As discussed previously in reference to the active water outlet 44 of Figure 2, the active water outlet 44 may emptying only partially the container 22 from the active water. Similarly the active water outlet of the embodiments of Figures 5 to 10 may also emptying only partially the container 122 or 222 from the active water. Figure 11 illustrates the container 122 in an opened configuration thereby showing the active water outlets 144. Figure 11 for the toilet basket 120 corresponds to the previous Figure 2 for the previous toilet basket 20. Figure 11 notably shows the support 142 for holding the water soluble block (not shown) above the active water outlet 144. Here the support 142 is made of two plates separated by a hole allowing the active water flow to flow below the water soluble block. This geometry of a single hole toward the support 142, or a limited cross section of the hole or holes through the support 142, allows to hold the water soluble block along all its lifetime. The cross section of the hole or holes through the support 142 for the flow of active water, may for example be less than 10 mm² or preferable less than 5 mm². More preferably, the cross section of the hole is around 8 mm², or 8,1 mm² or even lower, around 4 mm², or 4,06 mm².

[0040] Both of these Figures 11 and 2 illustrate a preferred embodiments where the container 22 or 122 further has an active water tank. This active water tank is only referenced in Figure 11 under the reference 160. The active water tank 160 is collecting the active water coming from the dissolving water soluble block (not shown in Figure 11). The active water outlet 44, 144 and the active water tank 160 being designed to define a stagnant active water tank volume. In other words, the position of the active water outlet define the presence of a stagnant part of the active water tank 160. As notably shown in Figures 2 and 11, the active water outlet 44, 144 are positioned above the lower inside level of the container 22 or 122. This is how the presence of a stagnant part of the active water tank 160 is allowed and how the active water outlet 44, 144 only partially empty the active water flow. The stagnant part of the active water tank volume 160 is preferably of at least 1ml, more preferably between 2 and 3ml.

[0041] The active water tank volume 160 and its stagnant part help to release active water after flush. In a preferred embodiment the active water tank 160 is adapted or designed to stop, or preferably, release the outlet flow of active water in 4 minutes or less after the stop of the flushing water flow. More preferably the active water tank 160 is adapted stop, or preferably, release the outlet flow of active water within a range of 2 to 3 minutes after the stop the flushing water flow. Having an active water flow maintained after the end of the flushing water allow to have a remaining active water in the drain of toilet bowl. This notably helps the sanitary level of the toilet bowl between the flushes.

[0042] Alternatively the active water outlet 44 or 144, or the assembly of all active water outlet, may be designed for emptying totally the active water formed in the container 22 or 122.

[0043] In the so far illustrated proposed embodiments, the active water outlets 44, 144 or 244 (shown in Figure 9) have been disposed at the back of the container 22, 122, 222. Alternatively or complementary, the active water outlet may also be positioned on the bottom side of the container. Such a positioning is particularly advantageous for the use of drip chambers that will discussed in reference to Figures 12 to 16.

[0044] Figures 12 and 13 are dedicated to a variant of the proposed toilet basket of Figure 5. This variant mainly differs from the embodiment of Figure 5 on the presence of drip chambers. Accordingly, the corresponding features of these proposed toilet baskets in Figure 5 and in Figures 12 and 13 will be referenced with the same reference signs with the features of the toilet basket of Figures 12 and 13 having a "3" before the two other digits of the reference sign instead of a "1". The drip chambers are referenced 370, in Figures 12 and 13. Notably as shown, two drip chambers 370 are preferably provided. Alternatively only one drip chamber may be provided. The drip chamber(s) 370 are collecting the drips of outlet flow of active water, dripping from the active water outlet. These drip chambers thereby help reducing the "after-dripping" effect. These drip chambers 370 are collecting the drops of active water after the flush and keep them until the next flush as their outlet is high enough to not overflow. Notably as shown in Figures 12 and 13, the drip chambers 370 present an opened front face. This opened front face allow the active water flow to exit from these drip chambers 370 to the toilet bowl.

[0045] Figures 14, 15 and 16 are dedicated to a variant of the proposed toilet basket of Figure 5 or to a variant of the proposed toilet basket of Figures 12 and 13. This variant mainly differs from the embodiment of Figures 12 and 13 on the fact that drip chambers are closed. Accordingly, the corresponding features of these proposed toilet baskets in Figures 12 and 13 and in Figures 14, 15 and 16 will be referenced with the same reference signs with the features of the toilet basket of Figures 14, 15 and 16 having a "4" before the two other digits of the reference sign instead of a "3". The drip chambers are referenced 472, in Figures 14, 15 and 16. These drip chambers 472 mainly differ from the drip chamber 370 of Figure 12 and 13 in that these drip chambers 472 present each a closed front face 476. Because of this closed front face 476, a drip chamber outlet is provided. Notably as shown in Figure 16, the drip chamber outlet 474 may be provided the on bottom side of each drip chamber 472. As for the variant of Figures 12 and 13, two drip chambers 372 are preferably provided but alternatively only one drip chamber may be provided.

[0046] Although limited embodiments of toilet baskets and their components have been specifically described and illustrated herein, many modifications and variations will be apparent to those skilled in the art. For example, the clean water tank may adapted to follow the curve tot the toilet bowl. The clean water tank may also be adapted to be placed on each face of the container, e.g. in the back as above described, in the front, or on either one of the sides of the container. This multiple positioning of clean water tank notably allows the presence of multiples clean water tanks.

[0047] Additionally, the clean water tank has been illustrated with a fully opened upper face for maximizing the collected water. The inlet upper face may alternatively be only partially open.

[0048] Besides, the clean water tank has been illustrated as a hollow case, but alternatively this hollow case may be replaced by a full porous material, such as a sponge, that will absorb and later the clean water.

[0049] Further, the clean water tank has been described and illustrated with one clean water outlet. Alternatively two or more clean water outlets may be provided in the clean water tank. The above discussed cross section of the one clean water outlet is distributed, for example equally, on the two or more clean water outlets. Similarly the active water outlets have been illustrated in a number of two, but these two active water outlets may be replaced by a single active water outlet or more than two active water outlets. The above discussed cross section of the active water outlet applies equally to the assembly of all active water outlet irrespectively of their number.

[0050] More further the clean water outlet has been illustrated on the bottom side of the clean water tank but the clean water outlet or outlet may be positioned on either side of the clean water tank.
