Toilet seat with a dispensing device

Description

[0001] The present invention relates to a device for dispensing a liquid containing at least one active ingredient into a toilet bowl that can be covered with a lid, according to claim 1.

[0002] For many people, unpleasant odors after using the toilet are a significant problem. Consequently, there is no shortage of suggestions and products that have been or are being developed to solve this problem.

[0003] These systems often extract unpleasant odors at the source. For example, German patent DE 20 2010 012 612 U1 describes a direct air extraction system via holes in the wall of a toilet bowl. German patent DE 20 2010 015 219 U1 describes odor extraction directly at the toilet seat.

[0004] A more advantageous approach than the technically complex air extraction system would be to absorb the unpleasant odor molecules, which can only exist as gases in the air, directly at their source using a sprayed liquid containing appropriate active ingredients. This liquid would act like a net, trapping the odor molecules. The effectiveness of the neutralizing liquid is certainly highest when it is released into a nearly enclosed space. However, this is only optimally achieved if the liquid is dispensed into the toilet bowl shortly before use, ideally while the user is already seated on the toilet seat. This significantly reduces the risk of the sprayed liquid and its odor-neutralizing effect escaping into the surrounding air.

[0005] Such a neutralization chamber is implemented with a metering device disclosed in EP 596 952 A1. This device comprises a liquid container suspended on the outside edge of a toilet bowl, from which a liquid line resting on the bowl rim leads into the toilet bowl, with a spray nozzle arranged at the outlet of the liquid line. The section of the liquid line resting on the bowl rim acts as a peristaltic pump, which, when pressure is applied to the toilet seat, delivers a defined spray into the interior of the toilet bowl via the nozzle structure.

[0006] German patent DE 1 609 234 PS and US patent 2,760,209 describe devices that also offer these advantages. The container, which holds the liquid containing at least one active ingredient, is made of an elastic material and is U-shaped. Its central section rests on the rim of the toilet bowl. Legs extend downwards from this central section on both sides, securing the container to the inside and outside of the bowl rim. A nozzle is located at the end of the leg that extends into the toilet bowl. When pressure is applied to the toilet seat, the container is compressed, releasing a specific quantity of liquid through the nozzles.

[0007] The devices described above are relatively complex. Using spray bottles would be less complicated. However, with this solution, the desired, nearly enclosed neutralization space is always only achieved after a significant time delay, because the sequence requires first removing the cap from the spray bottle, then spraying the contents into the open-topped toilet bowl, replacing the cap and setting the spray bottle down, then opening one's clothing, and only then more or less completely sealing the toilet bowl by sitting down.

[0008] These disadvantages are eliminated by a toilet air purifier described in DE 28 51 139 A1. It features a holder designed to accommodate an aerosol can. The holder is glued to the underside of the toilet seat. It supports an axially guided plunger, one end of which is in operative contact with the valve of the aerosol can, while its other end, facing the toilet seat, terminates in a conical head. When the toilet seat is closed, the conical surface of the head rests against the edge of the toilet seat. As the seat is opened and closed, the plunger, due to the conical shape of the head, is pressed against the valve of the aerosol can, causing it to open and release a spray into the toilet bowl.

[0009] In this device, the liquid containing at least one active ingredient is sprayed into an enclosed space to achieve optimal effectiveness through a close temporal sequence between application of the liquid and use of the toilet. The device itself is simple in design.

[0010] WO 2019 / 028 520 A1 discloses a toilet seat cleaning device. In one embodiment, this device has the following features according to the Figure 1 and 2 A docking device is located on the outside of the toilet seat, into which a replaceable container filled with cleaning fluid can be inserted. Several channels run radially outwards from the docking device within the toilet seat, ending in spray nozzles directed at the toilet bowl.

[0011] By inserting the container into the docking device, a liquid-side connection between the container and the channels is established.

[0012] The docking device has a push button; when pressed, the liquid is forced from the container into the channels by increasing or releasing the pressure and is then sprayed onto the toilet seat through the nozzles. The toilet seat can then be cleaned, for example with toilet paper, with the lid raised.

[0013] In another embodiment, which is described in the Figures 3 and 4As shown in WO 2019 / 028 520 A1, the docking device consists of a recess that projects downwards from the toilet seat and opens upwards. The recess accommodates two liquid-filled containers and can be closed by a lid that, when closed, is flush with the top of the toilet seat. A motion sensor is provided to trigger the spraying process.

[0014] US patent 2014 / 0 096 314 A1 also discloses a cleaning device for a toilet seat. This solution is very similar to that in patent WO 2019 / 028 520 A1. Here, the container for the cleaning fluid is located inside the lid and is an integral part of the lid. From the container, a multitude of channels extend radially outward within the lid, terminating in outlets directed toward the toilet seat.

[0015] The container is connected to an actuator, which is accessible from the top of the lid. Pressing the actuator compresses the air inside, which then flows into the container and forces the liquid through the channels to the outlets, spraying the toilet seat with cleaning fluid. A filling opening, accessible from the top of the lid, is provided for refilling the container with cleaning fluid.

[0016] KR 20 0 438 841 Y1 describes a cleaning device for the airspace above a toilet bowl that also wets the toilet seat, with the toilet lid serving as a holder for a spray bottle. The spray bottle is operated by a push button protruding from the front of the toilet lid.

[0017] The object of the present invention is to provide a further device for dispensing a liquid containing at least one active ingredient into a toilet bowl that can be covered with a lid.

[0018] This problem is solved according to the invention with a device having the features of claim 1.

[0019] This device is positioned in one of the most hygienic locations in a toilet, where it neither disturbs the user nor hinders cleaning. Furthermore, this location has the advantage that the device does not need to be adapted to different toilet geometries, such as varying rim widths or different distances between the bowl rim and the underside of the toilet seat.

[0020] In this device, the toilet lid has a through-opening in which the container is attached in such a way that, relative to its installation position, its top is accessible from the outside for manual pressure to trigger the release of liquid.

[0021] In the simplest case, namely when the dispensing device is integral with the container, the device consists of only one part and is therefore simple in design.

[0022] The container is easily replaceable, since in a version not belonging to the invention it simply needs to be inserted, snapped or screwed into the toilet lid, or, in the case of the use of an adapter sleeve according to the invention, it also needs to be inserted or snapped into this and, if necessary, locked in this.

[0023] In an alternative not belonging to the invention, the container is an integral part of the toilet lid and can be reversibly closed with a lid that is accessible from the outside by manual pressure to trigger the release of liquid.

[0024] The reservoir is easily refillable by simply unscrewing or removing the reservoir lid. Over the lifespan of a toilet seat, both the reservoir lid and the pump and spray mechanism (if not integrated into the toilet seat) can be replaced as separate components or as part of the dispensing head, if necessary.

[0025] The arrangement in the toilet lid allows a spray to occur even when the lid is closed, enabling the liquid to develop its optimal effectiveness in the toilet bowl, since there is usually only a short time between opening the toilet lid and a user sitting on the toilet seat, which effectively closes the toilet bowl again.

[0026] Further advantageous embodiments of the invention are set out in the dependent claims.

[0027] The invention is explained in more detail below with reference to exemplary embodiments.

[0028] One in the Figures 1 to 8 The illustrated device according to a first embodiment of the invention has an adapter sleeve 1 with a circular cross-section. The adapter sleeve 1 is open at the top and provided with a flange 2 at its upper edge. In its lower region, the adapter sleeve 1 is closed by a base 3, which has a square through-hole 4 in the center. The adapter sleeve 1 also has an external thread 5 onto which a clamping ring 6 with a corresponding internal thread 6.2 can be screwed.

[0029] For installation in a toilet seat 7, the adapter sleeve 1 is inserted from above through a circular through-opening 8 of the toilet seat 7, approximately in the middle of it ( Fig. 4 ), through until the flange 2 rests on the top of the toilet seat 7. The clamping ring 6 is then screwed onto the external thread 5 of the adapter sleeve 1 until its end face 6.1 rests against the underside of the toilet seat 7. The adapter sleeve 1 is thus secured to the toilet seat 7.

[0030] The device according to the invention further comprises a container 9, which receives the liquid containing at least one active ingredient. The container 9 is integrally formed with a top 10 and a bottom 11. A handle 10.1 is formed on the top 10, and an outlet nozzle 12 projects centrally from its bottom 11. This nozzle has an oval cross-section and a snap-on edge 13 at its free end. A control disc 14 is snapped onto the outlet nozzle 12. It has an oval inner cross-section and a snap-on edge 15, corresponding to the outlet nozzle 12. An outlet head 16 is snapped onto the control disc 14, which is fixed to the outlet nozzle 12. This outlet head has a circular opening 17 with a snap-on edge, corresponding to the outer circular cross-section of the control disc 14, and a 90° recess 18 for receiving the rotation limiter 18.1.The outer cross-section of the outlet head 16 is adapted to the cross-section of the through-hole 4 in the base 3 of the adapter sleeve 1. The outlet head 16 is equipped with a spray nozzle 19.

[0031] The control disc 14 has a through-opening 20. When the container 9 is not yet in use, the spray nozzle 19 of the outlet head 16 and the through-opening 20 of the control disc 14 are not overlapping, so that no liquid can leak out. To prevent unintentional rotation between the control disc 14 and the outlet head 16, a predetermined breaking point can be provided between the control disc 14 and the outlet head 16, which is destroyed during the first intended use of the container 9.

[0032] For intended use, the container 9 with its locking control disc 14 and locking outlet head 16 is inserted into the adapter sleeve 1. For this purpose, two diametrically opposed guide cams 21 are provided on the inner wall of the adapter sleeve 1 at its upper edge. Complementing these, guide grooves 22 are arranged on the outer wall of the container 9. To insert the container 9 into the adapter sleeve 1 in the correct alignment, the guide cams 21 are brought into contact with the entrances of the guide grooves 22. The container 9 can then be pressed into the adapter sleeve 1, whereby the guide cams 21 slide in the guide grooves 22 and finally reach an upper stop.

[0033] The guide grooves 22 transition at this point into a section 23 arranged at a right angle to them. The container 9 can now be rotated clockwise, whereby the guide cams 21 slide into the sections 23 until they reach an end stop. Since the control disc 14, which is fixedly mounted on the outlet nozzle 12, is moved along with the container 9 during this rotation, while the outlet head 16, which engages positively in the through-hole 4 of the adapter sleeve 1, does not rotate, a relative movement occurs between the control disc 14 and the outlet head 16, thereby destroying any predetermined breaking point. When the guide cams 21 bear against the end stops of the sections 23, an overlap between the through-hole 20 and the spray nozzle 19 is simultaneously achieved.

[0034] The top 10 of the container 9 is reversibly pressed in, so that by applying pressure to the top 10 in conjunction with the right-angled sections 23 of the guide grooves 22 or the bottom 3 of the adapter sleeve 1, liquid is displaced from the container 9 and sprayed into a toilet bowl through the spray nozzle 19 located in overlap with the through-opening 20.

[0035] To replace the container 9, it is turned counterclockwise in the adapter sleeve 1, which reseals it to be liquid-tight and allows it to be removed only when the spray nozzle 19 is closed. The grip strip 10.1 facilitates turning the container 9 when locking and unlocking it.

[0036] The Figure 9 and 10Figure 1 shows a further embodiment of the present invention. This device operates on the principle of a pump atomizer. The reference symbols from the previous embodiment are subsequently adopted for identical components.

[0037] In this embodiment, an adapter sleeve 1 is also used, which is provided with a flange 2 at its upper edge. In the installed state, this flange 2 rests on the top of a toilet seat 7. The adapter sleeve 1 is secured to the toilet seat 7 by screwing a clamping ring 6 onto the external thread 5 of the adapter sleeve 1. When fully screwed on, the end face 6.1 of the clamping ring 6 rests against the underside of the toilet seat 7.

[0038] A container 9, which holds a liquid containing at least one active ingredient, can be inserted into the adapter sleeve 1, which has an opening in its base 3. The container 9 is made in two parts, consisting of a lid 24 and a body 25. The top of the body 25 is open and is closed by the lid 24, which has a circumferential rim 26 that rests against the inner wall of the body 25 when in place.

[0039] The underside 11 is formed integrally with the body 25. A hollow cylinder 27 projects centrally from it; this cylinder is formed integrally with the underside 11 but can also be represented as a separate part. A piston chamber 28 is formed at the upper end of the hollow cylinder 27, into which a piston 29 formed on the cover 24 engages when assembled.

[0040] In its lower region, the hollow cylinder 27 opens into a chamber 30 formed in the underside 11. This chamber 30 is connected to the liquid-receiving interior of the container 9 via a through-opening 31 arranged in the underside 11.

[0041] The chamber 30 is closed on its underside by an outlet head 16. This is achieved by sliding the outlet head 16 onto a snap-on edge 32 formed on the underside 11. The outlet head 16 is provided with a corresponding snap-on edge 18 for this purpose. When the outlet head 16 is slid onto the chamber, the two snap-on edges 18 and 32 lock together.

[0042] A suction line 33 and a pressure line 34 are arranged in the hollow cylinder 27. The suction line 33 opens into the piston chamber 28 at its upper end and into the chamber 30 at its lower end. The upper end of the pressure line 34 also opens into the piston chamber 28, while its lower end opens into a spray nozzle 19 of the outlet head 16. A check valve 35 is installed between the spray nozzle 19 and the pressure line 34 to open and close it.

[0043] A section of the bottom of the piston chamber 28 is formed by a sealing disc 36, which ensures that the liquid can only leave the piston chamber 28 via the pressure line 34.

[0044] To actuate the device, the cover 24 is pressed inwards, causing the piston 29, in conjunction with the base 3 of the adapter sleeve 1, to move into the piston chamber 28. The cover 24 is then released, allowing the piston 29 to move back out of the piston chamber 28. The flexible material of the cover 24 ensures a corresponding restoring force.

[0045] When the piston 29 moves out of the piston chamber 28, a vacuum is created in the chamber, causing liquid to rise from chamber 30 into the piston chamber 28 via the suction line 33. When the lid 24 is pressed again, liquid is expelled from the piston chamber 28 and fed via the pressure line 34 to the spray nozzle 19 in the outlet head 16, causing the check valve 35 to open due to the pressure. The chamber 30 is refilled by supplying liquid through the opening 31 in the bottom 11 of the container 9.

[0046] The retention of the container 9 in the adapter sleeve 1 is achieved here by a clamping fit, locking mechanism or snap connection between the underside of the container 9 and the opening in the base 3 of the adapter sleeve 1, or via a clamping fit, locking mechanism or snap connection between the inside of the adapter sleeve 1 and the outside of the container 9.

[0047] The Figure 11 and 12 Figure 1 shows a third embodiment of the present invention, in which the device also operates on the principle of a pump atomizer. The reference numerals of the preceding embodiments are adopted for identical components.

[0048] In this embodiment, an adapter sleeve 1 is also used, which is provided with a flange 2 at its upper edge. In the installed state, this flange 2 rests on the top of a toilet seat 7. The adapter sleeve 1 is secured to the toilet seat 7 by screwing a clamping ring 6 onto the external thread 5 of the adapter sleeve 1. When fully screwed on, the end face 6.1 of the clamping ring 6 rests against the underside of the toilet seat 7.

[0049] A container 9, which holds a liquid containing at least one active ingredient, can be inserted into the adapter sleeve 1. The container 9 is a single piece and has a body 25, a top 10, and a bottom 11, from which an outlet nozzle 12 projects centrally, having an external thread 12.1. A ring cap 37 is screwed onto the external thread 12.1, from the base of which a hollow pin 38 projects, in which a piston chamber 28 is formed. When installed, the hollow pin 38 sits with minimal play in the outlet nozzle 12 of the container 9. Through-holes 39, passing through the base of the hollow pin 38, lead from the piston chamber 28 into the container 9. The outlets of the through-holes 39 on the piston chamber side are covered by a sealing ring 40.

[0050] A cap 41 is attached to the ring cap 37. The cap 41 has a circumferential flange 41.1 on its outer circumference, which rests against the base 3 of the adapter sleeve 1 from the inside. A hollow cylinder projects from the base of the cap 41, which, when installed, forms a piston 29 that engages in the piston chamber 28. A check valve 35 is arranged in the piston 29, which, when the device is not actuated, closes a branch channel 42 leading into the piston chamber 28, so that no liquid can reach a spray nozzle 19 arranged on the cap 41.

[0051] A coil spring 43 is arranged between the ring cap 37 and the locking cap 41, bearing against their bases. The coil spring 43 presses the container 9 in the adapter sleeve 1 into a rest position, which is reached when the stops 37.1 and 41.2 provided on the ring cap 37 and the locking cap 41 are in contact, as shown in Figure 11is shown.

[0052] To actuate the device, pressure is exerted on the top 10 of the container 9 against the force of the coil spring 43 and in conjunction with the circumferential flange 41.1 and the base 3 of the adapter sleeve 1, causing the container 9 to immerse itself in the adapter sleeve 1. This causes the piston 29 to penetrate deeper into the piston chamber 28, building up pressure in the piston chamber 28. This pressure opens the check valve 35, allowing the fluid displaced from the piston chamber 28 to flow to the spray nozzle 19 and be atomized. During this process, the sealing ring 40 seals the piston chamber 28 against the container 9. When pressure is released on the top 10 of the container 9, the coil spring 43 pushes the container 9 back into its rest position, causing the piston 29 to retract in the piston chamber 28 and creating a vacuum there. Due to the negative pressure, the sealing ring 40 opens, allowing liquid from the container 9 to flow into piston chamber 28.When pressure is applied again to the top 10 of the container 9, the next spray occurs.

[0053] The container 9 is held in the adapter sleeve 1 by a clamping fit, locking mechanism or snap connection between the cap 41 and the opening in the base 3 of the adapter sleeve 1.

[0054] The Figure 13 and 14 Figure 1 shows a further embodiment of the present invention. Here, the device is constructed according to the principle of a spray can. The reference symbols of the previous embodiments are adopted for identical components.

[0055] In this embodiment, an adapter sleeve 1 is also used, which is provided with a flange 2 at its upper edge. In the installed state, this flange 2 rests on the top of a toilet seat 7. The adapter sleeve 1 is secured to the toilet seat 7 by screwing a clamping ring 6 onto the external thread 5 of the adapter sleeve 1. When fully screwed on, the end face 6.1 of the clamping ring 6 rests against the underside of the toilet seat 7.

[0056] A container 9, which holds a liquid containing at least one active ingredient and a propellant, can be inserted into the adapter sleeve 1. It consists of a body 25, an upper part 10, and a lower part 11. An outlet nozzle 12 projects centrally from the lower part 11, onto which a valve seat 44 is slid. The valve seat 44 has two diametrically opposed windows 44.1 in which the liquid in the container 9 is located. The windows 44.1 open towards the inside of the valve seat 44.

[0057] A circular opening is provided in the base 3 of the adapter sleeve 1, which receives a nozzle cap 45. The nozzle cap 45 has a circumferential flange 45.1 on its outer circumference, with which it rests on the base 3 of the adapter sleeve 1 from the inside. On its inner side, the nozzle cap 45 has a circumferential stop 45.2 for the valve seat 44. A coil spring 43 is tensioned between the valve seat 44 and the nozzle cap 45, which presses the valve seat 44 against the stop 45.2 of the nozzle cap 45.

[0058] The nozzle cap 45 is equipped with a plunger 46, which terminates at its free end in a sealing disc 47. The sealing disc 47 rests against a shoulder of the valve seat 44, forming a seal due to the pressure force of the coil spring 43. Thus, no fluid can escape from the reservoir 1 when the valve is not actuated.

[0059] The plunger 46 has a spur channel 49 which terminates at one end in a spray nozzle 19 and at the other end in a transverse channel 48, which is designed as a through-bore through the plunger 46.

[0060] When the device is actuated by applying pressure to the top 10 of the container 9, the valve seat 44, in conjunction with the circumferential flange 45.1 and the base 3 of the adapter sleeve 1, is pressed into the nozzle cap 45 against the force of the coil spring 43. This causes the windows 44.1 to align with the outlets of the transverse channel 48, allowing liquid to flow via the transverse channel 48 and the branch channel 49 to the spray nozzle 19, where it is sprayed as a fine mist into the toilet bowl.

[0061] The container 9 is held in the adapter sleeve 1 by a clamping fit, locking mechanism or snap connection between the nozzle cap 45 and the opening in the base 3 of the adapter sleeve 1.

[0062] The Figure 15 and 16Figure 1 shows a further embodiment of the invention. Here, two adapter sleeves 1.1 and 1.2 are embedded in the toilet seat 7. As in the previous embodiments, adapter sleeve 1.1 holds a container with a liquid for odor neutralization. The other adapter sleeve 1.2, however, holds a container with a disinfectant. The containers are not visible in the illustration. They correspond to the containers 9 of the preceding embodiments. Outlets lead from the container 9 arranged in adapter sleeve 1.2 into branch lines 50, which terminate in the spray nozzle 19 located in the area above the toilet seat and which may optionally be components of the rubber stoppers between the toilet seat 7 and the toilet seat.When the container 9 is pressurized, the disinfectant flows to the spray nozzles 19 and is atomized there, which, with the toilet lid 7 closed, distributes it evenly on the toilet seat, which can then be cleaned with a cloth or a piece of paper.

[0063] In all of the above embodiments of the invention, the adapter sleeve 1 can also be glued, screwed, or snapped into place, or be formed integrally with the toilet seat 7. The clamping ring 6 can then be omitted, and the flange 2 is no longer strictly necessary.

[0064] Furthermore, for space reasons, the pressure-increasing systems can also be located inside the container, and the tops of the containers can also be flush with the toilet lid or recessed into the toilet lid.

[0065] A device 1 not belonging to the invention according to Figure 19The device has a container 51 that receives the liquid containing at least one active ingredient. The container 51 is an integral part of a toilet seat 7, i.e., it is formed in one piece with it. It has a circumferential side wall 52, which at its lower end transitions into a base 53 in which an outlet nozzle 12 for the liquid is provided. An outlet head 16 with a spray nozzle 19 is snapped onto this base. A through-opening 20 runs through the outlet nozzle 12 and opens into the spray nozzle 19.

[0066] In this embodiment, the container 51 is open at its upper end and can be reversibly closed by screwing on a lid 54 to allow refilling of the container 51. Other liquid-tight connections between the container 51 and the lid 54 are also possible. For this purpose, the side wall 52 is provided with an internal thread 55 at its upper end. The lid 54 has a corresponding external thread 56. To rotate the lid 54, it can be screwed on, as shown in the Fig. 17 and 18 It can be seen that it may also be equipped with an internal hexagon 57 or a handle strip 10.1.

[0067] The lid 54 is reversibly pressed in, so that by pressing on its top surface liquid is displaced from the container 51 and sprayed into the toilet bowl via the spray nozzle 19.

[0068] The Figures 20 and 21The figures show another embodiment not belonging to the invention. Here too, the container 51 is an integral part of a toilet seat 7. It has a circumferential side wall 52 which transitions at its lower end into a base 53, the latter being Figure 21 inwards, it is formed in one piece into a part of a piston pump with suction channel 33 and pressure channel 34.

[0069] The container 51 is open at its upper end and can be reversibly closed by screwing on a lid 54 to allow refilling. For this purpose, the side wall 52 is provided with an internal thread 55 at its upper end. The lid 54 has a corresponding external thread 56. This device corresponds in its design to the one described in Figure 9 depicted.
