The specific embodiment

In this manual, identical or corresponding part has identical or the corresponding reference numbering.Shown exemplary should not be interpreted into by any way to be restrictive but only to play the example illustration.

Forward accompanying drawing to, Figure 1A shows the reservoir shape of rectangle; Figure 1B shows to have the cylindrical reservoir shape of the cylinder axis of horizontal direction with respect to gravity direction.Accompanying drawing 1C show by the applicant also be designated as " Bala shape " according to reservoir shape of the present invention.

The denominator of these shapes is reservoirs 1, has comprised fluid 2 in this reservoir 1, and viscosity is higher than the viscous fluid of 2Pa.s usually.Because the cause (finding on gravity direction) of the geometry of the fluid delivery components 3 of in reservoir 1, arranging than the lower curtate branch at reservoir, corresponding with the fluid 2 in being included in reservoir 1, reservoir empties by lentamente fluid 2 being distributed outside the fluid delivery components 3.The size that can determine an embodiment makes the amount of 35mL be cleared in about 28 days predetermined period.

To hinder the insufficient pressure that fluid 2 flows out for preventing from reservoir, to produce, blow vent 4 can be provided more than liquid surface.In this embodiment, in the sidewall 5 that reservoir 1 and fluid delivery components 3 have, provide.Provide blow vent 4 on fluid 2, directly to be communicated with the top air cavity 6 of reservoir.

As the positive view of sidewall 5 among Fig. 2 A and the 2B and sectional view respectively shown in, in one embodiment, fluid delivery components 3 comprises that the fluid that is preliminary dimension and/or shape sends a plurality of through holes of passage 20 arranged in form on the sidewall 5 of fluid reservoir 1, they can be the suitable reservoir 1 of any kind of in principle or for example one of among Figure 1A-C shown in reservoir 1.Be not subjected to the restriction of any definition, in the context of the present specification, " predetermined " can mean that passage 20 has at least one wall that limits described opening or passage 20, described at least one wall of preliminary design and make with low relatively tolerance wherein, described tolerance according to the size of described preliminary design can be for example by the molding of the plastic products that have about same size with related passage 20 and/or boring preferably injection-molded in tolerance commonly used determine.Preferably, described at least one wall has at least one roughly straight substantial portion.

As if be not bound by any theory, the passage that is provided in the typical filter device is not that each all has predetermined size or structure, this is opposite with the present invention.This type of strainer can for example comprise sintered plastics, and its split shed is that the size and the structure of passage is almost irregular, and the size and dimension of opening or passage alters a great deal each other.

Show that with the present invention's test together compare with using known filter, a plurality of openings of preliminary dimension can cause the control preferably and the predictability of discharge.As if be not bound by any theory, the reservation shape of the wall of opening can cause the predictability preferably of discharge.Equally, test shows when an opening or several openings are plugged, to also have one or more openings to stay open, and causes the use of long term and does not have the shortcoming of allocation units.

As if be not bound by any theory, for example long relatively fiber of chip promptly is stuck in its passage at strainer, and these fibers can cover and stop up a plurality of openings.Equally, because the size of strainer passage has almost irregular shape, thereby for each strainer, the discharge of fluid can change.Owing to these reasons and also owing to other reason, to compare with a plurality of openings according to preliminary dimension of the present invention, strainer has the measurable discharge of relative mistake.

In a particular of pressing ozzle 21 layouts (referring to Fig. 2 A, B), fluid delivery components 3 can for example comprise the passage 20A-F of almost parallel.Ozzle 21 can be arranged in the sidewall 5 of reservoir 1.Fluid delivery components 3 does not need to be disposed in sidewall 5 places of reservoir 1, but for example can be disposed in any suitable place near reservoir 1 bottom.

Ozzle 21 can for example comprise moulding article.Ozzle 21 can for example have the cut-out in its side, and it forms passage 20A-F in use.In use, in the hole 22 on the ozzle 21 reeve walls 5, make the cut-out/wing passage 20A-F of ozzle 21 be covered by wall 5.As shown in the figure, ozzle 21 can be cylinder form, more particularly can comprise connector, and/or in sectional drawing, ozzle 21 can have T shape, makes that when in the opening 22 that it is injected fully sidewall 5, it adjoins the edge 22A (referring to Fig. 2 B) of described sidewall 5.

Other embodiment that has shown fluid delivery components 3 in elevation in Fig. 3 A and B and the sectional view respectively.Fig. 3 A and B show fluid delivery components 3, and wherein said a plurality of openings are included in the passage 20 that is shaped to the hole on the sidewall 5.These holes are pre-molding or can be for example excise by boring, cutting or with pin in manufacture process for example.The technician will recognize a plurality of selective replacement schemes.Randomly, sidewall can have and extends to reservoir 1 from sidewall 5 surfaces and make passage 20 (shown in Fig. 2 A, B and Fig. 3 A, B) can have the length l greater than sidewall 5 thickness with interior edge 23.This edge 23 also for example the situation among Fig. 2 A, the B equally help support plug type ozzle 21.

In one embodiment, the length l of passage is less than or equal to about 30 millimeters, preferably is less than or equal to about 20 millimeters, more preferably is less than or equal to about 10 millimeters.In the embodiment of a reality, the length l of passage for example is about 5 millimeters, or at least less than 10 millimeters.Each passage 20 can have and is less than or equal to about 3 millimeters, preferably is less than or equal to about 1 millimeter, more preferably is less than or equal to about 0.5 millimeter diameter d.These sizes can allow the lower cost of passage 20 usefulness to make, and the result is good, and failure risk is low relatively.For example, adopt these sizes, mould and/or fluid delivery components 3 will can not become too crisp, can prevent that in manufacturing and/or assembly process assembly problem from appearring in product in mould simultaneously.Same for relatively little channel size, can there be the danger of blocking channel during manufacture.Adopt described preferred sizes can help channel size (that is) reproducibility, length l and diameter d, and therefore improve dosing.In an exemplary, the length l of passage 20 and diameter d are respectively 2 millimeters, 4 millimeters and 0.35 millimeter.

The size of each passage 20 can be for example size by mould parts and/or resecting tool pre-determine.At least compare with the passage in the known filter for example, can keep the deviation between the shape of the tolerance of shape of each passage 20 and each passage 20 relatively little, passage in the described known filter has intrinsic irregularly shaped,, has intrinsic difference each other on shape and size that is.

Preferably, at least two size in the passage 20 (that is, diameter separately and length) and/or shape are the same, so that for example on the meaning of pressure, skin friction etc., each passage 20 is given fluid with being equal to.Like this, the speed that can equate substantially at least at first between each passage 20 of the fluid in the reservoir is distributed.In this manual, " diameter " of passage 20 is understood to for example width of passage 20, and wherein passage 20 can for example have circle or the angle cross section is arranged.Above the passage that the fluid of being explained " wait and give " also can be by having approximately identical cross section (promptly have the same stream output but needn't have each identical shaped passage) is realized.

In one embodiment, fluid delivery components 3 has the passage 20 between two and 20.The number of passage 20 can be relevant with expection distribution speed and/or the viscosity of fluid, the desired use of allocation units etc.An embodiment of fluid delivery components 3 comprises for example two, three, four, five, six, seven, eight, nine or ten passages 20.This type of fluid delivery components 3 can for example help emptying the amount of the fluid 2 between 10 and 200 milliliters in about 10 to 200 days, more particularly help emptying about 35 milliliters amount in about 28 days.The favourable quantity of passage 20 (not shown in the test) is six.

Following table shows that the different basis weights feeding system with different fluid delivery components is the result of the test of allocation units.

Shown in test, first dosing system of being tested is equipped with strainer and single passage, and second dosing system comprises four passages 20, and the 3rd dosing system is equipped with eight passages 20.For each dosing system 500, test sample till reservoir empties, that is, and at 28 days or longer time durations.500 samples of four-way fluid delivery components 3 show to stop up at test period at all, and eight passage fluid delivery components 3 in all 500 test samples only blocked a day.The dosing system that can find four-way 20 dosing systems and eight passages, 20 dosing systems and have other a number passage 20 between four and eight is acceptable.As shown in the figure, adopt the dosing system of strainer to show above 10 obstructions of a week.

In addition, if passage 20 is arranged as closer to each other, then can be favourable.Like this, can for example arrange ozzle 21, perhaps for example on the close zonule of reservoir 1 bottom, arrange fluid dispensing components 3 at least.Therefore, can be each other arrange fluid dispensing components 3 described openings at a distance of closer distance D, described distance D is the distance between the edge of two adjacency channels 20.For example, the distance D between two adjacency channels 20 of fluid delivery components 3 is less than or equal to about three millimeters, preferably is less than or equal to about one millimeter, or at least between five and 0.20 millimeters.

Described other embodiment in the following description, it comes down to obtain from the unpub European Patent Application No. 06076793.6 of submission on September 27th, 2006, and its complete content can advantageously combine with allocation units according to the present invention.By will fluid delivery components according to the present invention being applied to improve controllability and predictability in the allocation units described in european patent application 06076793.6 in some scheduled time slot inner fluid discharge.

Expectation provides appropriateness and stable discharge, and described discharge in time and does not obviously change.Specifically, when reservoir almost will empty, it still was in acceptable level.In addition, the pure and fresh power of distributor (wherein only having described reservoir 1) will become very inhomogeneous, in fact this mean that described device is unpractical: the amount of pure and fresh liquid 2 too much will produce almost full reservoir 1, and it is last, for the reservoir that almost empties, the amount of pure and fresh liquid 2 can be not enough to the pure and fresh level that provides required.

Yet one of difficulty that will overcome is to distribute speed (representing with ml/ days), the relation that exists between the high H of post, the fluid density p of itself and fluid and the passage length L of liquid viscosity η and fluid delivery components 3 and the diameter r:

Formula 1

Therefore, can find out that when the post height diminishes, the discharge of fluid 2 will reduce when reservoir 1 empties, therefore reach lower dosing speed.

The digital value of indication dosing rate variation is the initial dosing speed that obtains under 100%, 10% filling rate of reservoir 1 respectively and the ratio of dosing speed, as in the top view of Figure 1A, B and C and the bottom view respectively shown in.The composition of supposing fluid 2 does not change (hereinafter will describe in further detail), and this value depends on reservoir 2 shapes and can be expressed as the aspect ratio of volume height.Determine the volume of 100%, 10% filling rate of reservoir 1 respectively.Ideally, wherein dosing speed keeps constant in time, and with highly irrelevant, this value should be 1.Therefore, at 10% packed space place, for box-like volume, packed height will also be 10%, and better characteristic is will still have for example 25% packed height at 10% packed space place.In fact, acceptable value will be between 1 and 4, preferably between 1 and 3.3.

Forward Figure 1A now to, for rectangular shape, the post height is linearly dependent on the Fluid Volume that is included in the container.Therefore, 10% fill level will cause 10% height, reach 10 dosing ratio.Therefore, rectangular shape has reached the significant difference on dosing ratio during the application apparatus.

Figure 1B shows applicable to the selective alternative form of distributing purpose, be applicable to the distribution purpose in the lavatory specifically, because this shape is clamped under the edge of flush toilet easily, and the size of diameter can be determined to be roughly the width (not shown) corresponding to the edge.A kind of like this diameter can be in the scope of 20-50mm, preferably about 35mm.The reservoir of Figure 1B has cylinder form, and this shape has the cylinder axis that points to respect to the gravity direction level.Here the dosing ratio is 5.8, because first height H 1 is 34mm, and represents that the height H 2 of 10% fill level is 5.9.Although this ratio almost than the rectangular shape of Figure 1A good half, still there were significant differences yet it is with the ideal value of calculating.

The last shape that shows according to an aspect of the present invention of Fig. 1 C, wherein dosing speed is in the scope of 1-4.Specifically, the reservoir shown in Fig. 1 C 1 is formed as the frustoconical shape with inclined floor.The volume of the major part that is provided in the top of reservoir generally is provided this shape, and the dosing speed less than 3.3 is provided usually, is 10.5 for 10% fill level height specifically, and the initial fill level height with respect to 33.5 is 3.2.Therefore, for shown in shape more constant dosing speed can be provided.Specifically, because the cause of inclined floor, most relatively volume is assigned with has high relatively post height, because compare with the remainder of volume, relatively little at the volume at place, reservoir bottom, it means constant relatively dosing speed.Only assignment period than the rear section in, when volume near zero the time, the post height obviously dwindles and dosing speed descends.

Fig. 4 shows another group embodiment, and they are modification (Fig. 4 A and Fig. 4 B) of the butt-coniform shape shown in Fig. 1 C.Figure A and B show three views respectively, are in 100% upper view of filling condition, are in 10% and fill the medial view of condition and show the lower view of the embodiment in the sectional drawing of reservoir main shaft.Specifically, in Fig. 4, what shown reservoir wherein is fit to have each embodiment of the direction more vertical than the direction on the top of reservoir than the lower part size.Therefore, in fact, compare, produced less lower volume 7 with the big volume 8 that the position is higher.Therefore, in fact give discharge of the fluid 2 of this big volume 8, provide constant relatively height along the lower volume 7 of vertical direction.In fact, for Fig. 4 A, this has produced step form 9, and wherein the fraction of volume is orientated so that be created in the still acceptable height post in required flow rate aspect downwards.

Similarly, with reference to Fig. 4 B, provide lower volume by the elongated passageway 10 that forms in the bottom of reservoir 1, for example by tongue type 11 is provided in the Lower Half of reservoir, its each wall provides path 10 together with the reservoir sidewall.The dosing ratio of these other embodiments or even more useful and to calculate stepped ramp type for Fig. 4 A be about 2.5 and be about 2.3 for the elongated passageway of Fig. 4 B.

Fig. 5 shows that they all deviate from cone shape more as some some other other reservoir shapes of further modification.Specifically, the passage 12 that the embodiment described in Fig. 5 A and Fig. 5 B has the perpendicular of particular design, it limits the post height of substantial constant for the major part of fluid 2, and fluid 2 mainly is included in the big volume 8 that is arranged on these passages 12.Therefore the dosing ratio of these embodiments even approach ideal value 1 provides almost constant dosing speed.For the embodiment described in Fig. 5 A (second height H 2 with 25.25mm of first height H 1 of 52mm and 10% fill level), the dosing ratio is equivalent to 2.For second highly the embodiment of Fig. 5 B of first height with 50mm and 41mm, the dosing ratio is equivalent to 1.2.

Fig. 6 is presented at dosing speed figure decrescence in any of different shape shown in Fig. 1.Specifically, for 28 days life-span, the conical butt of Fig. 1 C " Bala " shape is relatively best near constant ideal form, because approach 1 with respect to the cylinder form dosing speed of the rectangular shape of Figure 1A and Figure 1B most at All Time basically.

Fig. 7 shows the schematic side section figure of an example of distributor 13, wherein can accurately determine dosing speed by suitably adjusting fluid 2 about the viscosity of fluid delivery components 3.By the cover cap 14 shown in for example adopting or a certain other protector protective ventilation hole 4 suitably, flushing water can not contact the fluid 2 within the reservoir 1.The two all provides gravity vent 4 and fluid delivery components 3 on same sidewall 5, thereby provides a kind of opening to flow out and the compact way of gravity vent, for example seals 15 by what use was drawn out cover cap 14 to tearing of under shed 16.Fluid delivery components 3 has the moisture structure that is groove 17 forms, size be fit to provide across or near the water film of opening in case fluid stopping body 2 become dry.

Therefore, in use, by flushing, water reach sidewall 5 than lower part, and make fluid delivery components 3 wetting specifically.By absorption water is remained in the groove 17, when fluid is sent passage 20 dryings, keep the fluid humidity like this.This mechanism provides a kind of method of protecting fluid 3 not become dry, becomes dry then to cause harmful obstruction of passage 20.Although in general this be regarded as worthless, yet (finally) stops to discharge and by using flushing water to dredge release channel 18 from passage 18 release fluids when this obstruction also can be used to not use in the lavatory.Although in this embodiment, groove is shown as moisture structure, and for example the rib shape is given prominence to structure to other embodiment or capillary pipe structure also is possible.

Although in Fig. 7, only shown the lateral view of cover cap 14, yet preferably cover cap 14 is preferably generally deferred to the profile of reservoir 1 and is covered the major part of sidewall 5, stay for a short time, be used to enter some flushing waters and come wetting fluid to send parts 3 passage 20 open-ended specifically under shed.Container preferably has visual appearance, and it comprises colored cleaning fluid.Yet, found that blue cleaning fluid causes stain easily on toilet, this is not attractive in appearance in appearance.Therefore, on the one hand, expectation provides the container that comprises colorful substance; On the other hand, the stain that do not caused by described colorful substance of expectation is bothered.For overcoming this problem, preferably, reservoir comprise transparent colored wall and wherein fluid have achromatic transparent nature.Therefore, the visual appearance of distributor 13 is that it comprises colored fluid, yet in use, because the neutral transparent nature of fluid, thereby it can not provide stain.

Though specific embodiments of the present invention described above, should be appreciated that can with described different enforcement the present invention.Specifically, to be intended to be illustrative rather than restrictive to above-mentioned manual.Therefore, it will be apparent to those skilled in the art that and to make amendment for aforesaid the present invention and do not deviate from the scope of described claim.

Specifically, an embodiment can arranging allocation units provides the volume of major part so that the moulding reservoir makes in the top of reservoir, so that dosing ratio (be defined as and limit the height ratio that 100%, 10% of reservoir is filled the volume height of ratio respectively) scope is between 1 and 4.0.Can other embodiment of following layout.Reservoir can be molded into frusto-conical shape with inclined floor; Can determine reservoir than the size of lower part to have the more vertical direction of direction than the top of reservoir; Can determine reservoir than the size of lower part so that the passage between the top of fluid delivery components and volume to be provided; Fluid delivery components can have size be fit to provide across or near the moisture structure of the water film of opening in case the fluid stopping body become dry; Moisture structure can be provided as the groove in the sidewall that fluid delivery components is provided therein; Blow vent can with cover cap protect and with the common reservoir sidewall of fluid delivery components on provide, blow vent provides the direct ventilation of the top air cavity of reservoir, and cover cap has under shed so that allow flushing water near fluid delivery components and be used to protect blow vent and avoid falling flushing water; Reservoir can comprise that transparent colored wall and wherein said fluid have achromatic transparent nature.
