Definitions

  • the invention refers to an automatic dispenser device for liquids or gels in toilet bowls.
  • toilet bowls are cleaned and deodorized by using products in solid, gel or liquid form. Such products are placed in appropriate containers arranged in the flushing cistern in a way to be hung from the rim of the bowl. Also these containers are arranged in order to be exposed to the flow of the flushing water.
  • liquid or gel containers are arranged with the output mouth facing downward and the dispensation of the product occurs by simple drop.
  • Such containers are not provided with a closure device for the output mouth which assures the control of the outflow of the product in a way independent of the duration of the water flow.
  • a dispenser device comprising at least one cartridge containing at least one liquid or gel and a support body for said cartridge which is provided with a bottom mouth for the outflow of liquid or gel, at least one first valve urged to close a first section of said mouth from the outside and control means responsive to each water flow to open said first valve, characterized by comprising at least one second valve for closing a second section of said mouth during each water flow, said at least one second valve being spaced from said at least one first valve so as define between said first and second sections of the mouth a quantity of said liquid or gel which is delivered by the dispenser device upon each water flow, there being provided valve connecting means for causing said at least one second valve to open said second section of the mouth when said at least one first valve is closed and to close said second section of the mouth when at least one first valve is open.
  • the present invention is possible to provide a dispenser device for liquids or gels of the automatic type because its operation occurs by means of a water flow used for cleaning the toilet bowl. Also the quantity of the liquid or gel to deliver is determined by the volume intercepted in the mouth between the two valves.
  • the device can be made so as to allow the single or simultaneous delivery of several products; in such case the dispenser device comprises several cartridges and double valves units in measure equal to the cartridges being used.
  • a dispenser device comprises a cartridge 4 (Figure 1) containing a product, liquid or gel, to deliver inside a toilet bowl.
  • the cartridge can comprise a hole 12 in the upper part ( Figure 2) for putting into communication an air bubble 13 ( Figure 7) formed inside the cartridge 4 with the outside in order to assure the atmospheric pressure inside the cartridge 4.
  • the cartridge 4 is provided in the bottom with a plug 5.
  • the hole 12 is closed by suitable means, for example by an adhesive label or by a removable plug.
  • the dispenser device comprises a support body 1 ( Figures 3 and 4) on which the cartridge 4 should be inserted.
  • the body 1 is provided with an additional hook 2 adapted for the fastening to a rim of the toilet bowl and with an element 101 for spacing it from the wall of the toilet bowl.
  • the dispenser device comprises a unit 3 ( Figure 5) according to a first embodiment of the invention which should be inserted in the body 1.
  • the unit 3 is coupled with the body 1 by rotatably coupling of ends 21 of the unit 3 in suitable housings 22 in the body 1.
  • the unit 3 comprises leaf springs 14 operating by means of projections 15 on the striker plates 16 of the body 1, an upper valve 25 adapted to be inserted in the mouth 9 of the body 1 and a lower valve 17 adapted for closing the output section 18 of the mouth 9; the valves 17 and 25 are spaced form each other and are united whit each other by means of a tang 26.
  • the dispenser device unit 3 comprises also a hole 27 placed on a spoon shape plate 20 next the valve 17.
  • the operation of inserting of the cartridge 4 in the body 1 provides the cutting of a closing diaphragm 555 of the plug 5 by means of teeth 6 belonging to a mouth 9 of the body 1 which is provided with an input section 29 and the output section 18; in this way, while the diaphragm 555 floats in the product 8, the product 8 contained in the cartridge 4 can go out from the cartridge 4 through the mouth 9 to deliver it into the toilet bowl.
  • the dispenser device so obtained can be fastened to the rim 100 of the toilet bowl 200 by means of the hook 2, as shown in Figure 7.
  • the arrival on the dispenser device of the water flow determines the working phase of the dispenser device.
  • the water flow 19 generates a thrust on the spoon-shape plate 20 of the unit 3; the thrust causes a rotation of the dispenser device unit 3 around the ends 21 placed in the housing 22 of the body 1.
  • the stop of the rotation is defined by the contact of the ends 23 (opposite to the ends 21) with the projections 24 of the element 101 belonging to the body 1.
  • the leaf springs 14 are additionally loaded.
  • the upper valve 25 by placing itself inside the mouth 9 and because of the viscosity of the product 8, interrupts the output of the product 8 from the cartridge 4. Therefore only a certain quantity or a dose of the product 8 can outflow from the cartridge 4.
  • the dispenser device unit 3 also provides a dose of the product 8 contained in the cartridge 4 at each water flow; this dose does not depend on the time period wherein the water flow 19 is present inside the toilet bowl 200 but it depends on the distance between the input 18 and output 29 section of said mouth 9 and also on the size of the mouth 9, that is on the quantity of the product 8 intercepted in the mouth 9 between the valves 17 and 25.
  • the hole 27 of the spoon-shape plate 20 allows that the water accumulated during the working phase outflows through.
  • a dispenser device according a second embodiment of the present invention is shown in Figures 12 and 13.
  • the dispenser device of the second embodiment differs from the dispenser device of the first embodiment for the introduction of at least one contrast spring 32 in the place of the leaf springs 14.
  • This at least one contrast spring 32 is arranged in a suitable cavity 34 formed in the element 101 of the body 1 and it is engaged with pins 35 of the element 101 and with pins 330 of the end part 33 of the spoon-shape plate 20 of the unit 3.
  • the spring 32 operates for closing the valve 17 on the output section of the mouth 9 after each water flow.
  • the spring 32 therefore is further loaded when the water flow acts on the unit 3 and the valve 17 is opened for the outflow of the product 8 ( Figure 13) while the spring 32 acts on the valve 17 for closing it in absence of the water flow ( Figure 12).
  • a dispenser device according a third embodiment of the present invention is shown in Figures 14 and 15.
  • the dispenser device of the third embodiment differs from the dispenser device of the first embodiment for the introduction of a traction spring 36 in the place of the leaf springs 14 and of a support 37 integral with the body 1 and arranged inside the cartridge 4.
  • the support 37 is provided with openings 38 for the passage of the product 8 through them.
  • the spring 36 is hinged with the upper part of the support 37 and with the valve 25 of the dispenser device unit 3.
  • the spring 36 operates for closing the valve 17 on the output section of the mouth 9 after each water flow.
  • the spring 36 therefore extends when the water flow acts on the unit 3 and the valve 17 is opened for the outflow of the product 8 ( Figure 15) while it acts on the valve 17 for closing it by retraction in absence of the water flow ( Figure 14).
  • a dispenser device according a fourth embodiment of the present invention is shown in Figures 16 and 17.
  • the dispenser device of the fourth embodiment differs from the dispenser device of the first embodiment for a new type of dispenser device unit 39; the last is not hinged rotatably with the body 1, as the unit 3 of the preceding embodiments, but is hinged with at least two springs 40 arranged in lower projections 42 of the body 1 and engaged with pins 420 thereof and with pins 410 of the unit 39. These projections 42 are formed respectively in the element 104 and in the end 41 of the lower part of the body 1 which is opposite to the element 104.
  • the dispenser device unit 39 is provided with a the spoon-shape plate 43.
  • the springs 40 operate for closing the valve 170 on the output section of the mouth 9 after each water flow.
  • the springs 40 therefore are loaded when the water flow 19 acts on the unit 39 and a lower valve 170 (which is similar to the valve 17 and has the same function) is opened for the outflow of a certain quantity of the product 8 (Figure 17) while an upper valve 250 (which is similar to the valve 25 and has the same function) closes the mouth 9.
  • the springs 40 which are loaded by the water flow 19, act on the lower valve 170 for closing it in absence of the water flow ( Figure 16).
  • a dispenser device according a fifth embodiment of the present invention is shown in Figures 18 and 19.
  • the dispenser device of the fifth embodiment differs from the dispenser device of the first embodiment for the introduction of an upper valve 46 in the place of the valve 25.
  • This valve 46 is connected with the valve 17 in a non-rigid way, in fact the valves 46 and 17 are connected with each other by means of a flexible cord 47.
  • the upper valve 46 is made up of a half cap shape element having a specific weight lower than the product 8 to deliver; in this way the upper valve 46 floats in the product 8 inside the cartridge 4 ( Figure 18). Therefore when the lower valve 17 is opened for the outflow of the product 8 ( Figure 19) the upper valve 46 covers an optimal vertical movement for the transfer operation of the product 8 from the cartridge 4 to the mouth 9.
  • a dispenser device according a sixth embodiment of the present invention is shown in Figures 20 and 21.
  • the dispenser device of the sixth embodiment differs from the dispenser device of the first embodiment for the introduction of an upper valve 55 in the place of the valve 25 and for the introduction of a mouth 56 different with respect to the mouth 9.
  • the input section 156 of the mouth 56 is shaped in a such way that the valve 55 can carry out a mechanical closure of the mouth 56 in the working phase.
  • the valve 55 is coupled with the valve 17 by means of a projection 54 of the dispenser device unit 3 in the central part of the lower valve 17.
  • a dispenser device according a seventh embodiment of the present invention is shown in Figures 22 and 23.
  • the dispenser device of the seventh embodiment differs from the dispenser device of the first embodiment for the introduction of an different type of a mouth 62 and of a dispenser device unit 60 always movable between the rest and working phases by means of the water flow 19.
  • the unit dispenser device 60 is provided with a vertical projection 61 (which is transversal to the spoon shape plate 59 of the unit 60) acting on a ball 65.
  • the mouth 62 is provided whit upper horizontal projections 63 on the input section 162 and lower horizontal projections 64 on the output section 262.
  • the projections 63 and 64 are transversal to the flow of the product 8 through the mouth 62 and are adapted for coupling whit the ball 65 on which the projection 61 acts; the ball 65 acts as a shutter for the input and output section of the mouth 62 . Therefore the coupling of the upper horizontal projections 63 with the ball 65 allows the ball 65 itself to act as a valve for the closure of the cartridge 4 at rest phase ( Figure 22) while the coupling of the lower horizontal projections 64 with the ball 65 allows the ball 65 itself to act as a valve for the closure of the cartridge 4 in the working phase ( Figure 23).
  • the quantity of the product 8 which outflows from the cartridge 4 is defined by the distance between the input and output sections of the mouth 62 and by the change of position of the ball 65 between the rest phase and the working phase.
  • a part of the product 8 is delivered by the cartridge 4 in the passage between the rest phase and the working phase for emptying the mouth 9 and said part of the product 8 can outflows from the mouth 62 at the successive rest phase when the projection 61 of the control means 60 acts (by means of elastic means as leaf spring which are not shown in Figures 22 and 23 but which are similar to the leaf spring 14 in Figure 5) on the ball 65 to open the section 262 and to close the section 162.
  • the ball 65 which has a weight higher than the product 8, goes down for gravity during the working phase in presence of the water flow 19.
  • the spoon shape plate 59 of the unit 60 is not provided with a hole because the quantity of the product 8 which is delivered at rest remains on the spoon shape plate 59 for carrying out a perfuming action between a water flow and one following.
  • a dispenser device according an eight embodiment of the present invention is shown in Figures 24-27.
  • the dispenser device of the eight embodiment differs from the dispenser device of the first embodiment for the possibility of delivering more products. Therefore the dispenser device of this eight embodiment comprises two cartridges 48 containing different products to deliver (Figure 24), or alternately a single cartridge 480 provided with two chambers 481 containing two different products to deliver (Figure 27).
  • Said dispenser device comprises a body similar to the body 1 and provided with two mouth 9 one for each cartridge 48 or for each chamber 481 and a dispenser unit similar to the dispenser unit 3 provided with two lower valves 17 and two upper valves 25 for the mouths 9 and with a single spoon shape plate 20.
  • the chambers 481 are provided with plugs 5 with closing member 482 which are pushed inside the chambers 481 by engaging with the mouths 9.
  • the meaning of the dispenser device of this eight embodiment is similar to the meaning of the dispenser device of the first embodiment unless, in this case, two quantity of different products contained inside the two cartridges 48 are delivered.
  • the feature of delivery more products by using two cartridges and a dispenser unit with two upper valves and two lower valves which belonging to this eight embodiment, which is substantially represented as a variant of the first embodiment, can be applied to all the preceding embodiments.
  • FIGS 28 and 29 a new type of body 110 for the dispenser device according to invention is shown.
  • the body 110 is different from the bodies of the aforementioned embodiments because it comprises a conveyor 111 for the water flow 19.
  • This conveyor 111 is advantageous above all in the case of the water flow inside the toilet bowl 200 occurs in tangential to its internal walls.
