Definitions

  • the present invention generally relates to a device for dispensing an active ingredient preparation into a toilet bowl, comprising a receiving container which is to be disposed in the toilet bowl beneath the rim thereof and across which water flows during flushing.
  • a device of the type in question is known from U.S. Pat. No. 4,168,551.
  • the device shown there comprises a chamber including a toilet block and, downstream, a further chamber.
  • the chamber including the toilet block is separated from the further chamber by a separating wall having at least one opening.
  • Disadvantages of this known device are the multi-piece design and the use of a grating-like wall for retaining the separating wall, which thus result in a cost-intensive design.
  • FIG. 1 shows a perspective view of the device, the device being shown in the open state and without a toilet block;
  • FIG. 2 shows a sectional view through a device according to the invention along cutting plane A-A from FIG. 1 ;
  • FIG. 3 shows a sectional view through a device according to the invention, comprising a toilet block, along cutting plane B-B from FIG. 1 .
  • the device according to the invention for dispensing a water-soluble active ingredient preparation from a toilet block into a toilet bowl comprises a receiving container, which is to be arranged in the toilet bowl, for the toilet block across which flushing water can flow, wherein the receiving container: can be fastened to the rim of the toilet bowl by way of a holder, forms a pan having a pan bottom in the region of the container that is at the bottom in the usage position, has at least one inlet and one outlet for the flushing water, and is fluidically connected to the toilet bowl via the outlet, wherein a siphon is arranged upstream from the outlet, wherein the siphon defines a triggering threshold level and a terminating threshold level for flushing water in the receiving container, by way of which a discharge of flushing water through the siphon can begin and stop, and the receiving container comprises a bearing plate having a bearing surface, wherein the bearing plate holds the toilet block above the terminating threshold level, and wherein the bearing plate is fastened to the siphon.
  • the receiving container is held by the holder on the toilet bowl so that, in the usage position, the pan is located beneath the holder. In the usage position, the toilet block is held above the terminating threshold level by way of the bearing plate.
  • the holder is preferably a bracket-shaped suspension holder, for example.
  • the device according to the invention has the advantages that continued dripping of partially dissolved active ingredient substance into the toilet bowl is reduced or even entirely prevented.
  • the flushing water can flow across the toilet block and flow freely to the pan bottom and, with time delay, through the outlet into the toilet bowl. Once the flow through the siphon has begun, the pan is essentially emptied. The flushing water thus flows out of the receiving container after flushing, without any noteworthy water residue remaining.
  • the bearing plate is preferably designed so that the toilet block is held on the side of the bearing surface.
  • the bearing surface is the surface area of the upper side of the bearing plate in the usage position.
  • the bearing plate is designed so that flushing water can simultaneously run across the toilet block and drain out of the same, so that the amount of water left behind on the toilet block is minimized
  • the toilet block is kept substantially dry between two consecutive flushes. This is achieved by minimizing the contact area between the bearing plate and the toilet block.
  • the bearing plate can have a minimum extension between the side walls of the receiving container, which is described in more detail below.
  • the siphon comprises a siphon cover, which has a one-piece design. It is further preferred for the bearing plate and the siphon cover to have a one-piece design. This results in a particularly cost-effective configuration, which additionally is easy to mount in the overall arrangement thereof.
  • the siphon comprises an outlet pipe and a siphon cover.
  • the siphon cover comprises an outer pipe, which has a larger diameter than the outlet pipe.
  • the outer pipe is closed at one end by the bearing plate.
  • the siphon cover is arranged at least partially around the outlet pipe, so that an annular gap-shaped flow duct section is formed in the region between the outlet pipe and the outer pipe. Further downstream, the outlet pipe itself forms the flow duct.
  • the flow duct is also delimited by the side of the bearing plate which is located opposite the bearing surface.
  • the toilet block is supported longer during use. This ensures that the dispensing of active ingredient preparation into the toilet bowl takes place constantly over an extended period of time.
  • the siphon cover, and thus the bearing plate at the same time, is placed onto the device using a simple production step.
  • a pipe within the meaning of the invention is a segment of an elongated hollow body and can have a circular or another cross-section, such as rectangular or oval.
  • a cross-section (cross-sectional surface) shall be understood to mean a vertical cross-section (vertical cross-sectional surface).
  • the receiving container comprises support means, which together with the bearing plate are designed to hold the toilet block in position, which is to say above the terminating threshold level.
  • the support means is preferably designed as one piece with the receiving container.
  • the support means preferably has a surface area (the support surface) of less than 5 mm 2 , preferably less than or equal to 3 mm 2 . Due to the small surface area, contact with the toilet block is minimized, and consequently also the volume of residual water that remains adhering to the toilet block.
  • the number of support means is preferably no more than 10, further preferably no more than 6, still more preferably no more than 4. Due to the low number of support points, contact with the toilet block is likewise minimized, and consequently so is the volume of residual water that remains adhering to the toilet block.
  • the bearing surface is larger than the outside cross-sectional surface of the outer pipe of the siphon cover, preferably 1.5 times larger, further preferably 2 times larger.
  • the bearing surface is larger than pi*(d 2 )/4, wherein d is the outside diameter of the outer pipe of the siphon cover.
  • the bearing surface is preferably smaller than half, especially smaller than 1 ⁇ 4 of the maximum surface area in this plane.
  • the maximum surface area is the inner cross-sectional surface of the receiving container. It is furthermore necessary to keep the bearing surface sufficiently small, so that the water flow dynamics within the receiving container are maintained.
  • the siphon should begin to discharge the water, in particular when the toilet block also includes an active ingredient preparation having a cleaning function. It was established that a very large bearing surface, even if it is perforated or pierced in another manner, delays the flow within the receiving container for too long and results in continued dripping or in residual water in the pan.
  • the device is preferably elongated and conforms to the rim of the toilet bowl.
  • a front wall which is arranged in the direction of the toilet bowl interior
  • a rear wall which is arranged in the direction of the toilet bowl wall
  • Spacers are preferably present on the outside of the rear wall, so as to prevent flushing water from remaining between the rear wall and the toilet bowl wall as a result of capillary action. The spacers are important to prevent streaking and stains on the toilet bowl wall.
  • the bearing plate for the toilet block to extend at least 80%, further preferably at least 90%, between the front and rear walls. In this way, the toilet block is held on the bearing plate even after half of it has been consumed.
  • two- or multi-piece toilet blocks these may be two joined parts (such as glued together or coextruded), or two separate parts, which are packaged together in a water-soluble PVA film, for example, prior to use.
  • one part preferably includes a cleaning action and another part a coloring action. It is also possible, of course, to have more than two parts within a toilet block, and moreover additional active ingredient functions are possible as well, such as bleaching, lime scale prevention or hygiene functions.
  • the toilet block is two-piece and one part includes a coloring action
  • this part it is particularly preferred for this part to have a color that is the same color as the receiving container. This color is not colorless or white.
  • the further part, which does not include a coloring action has another color, preferably white. In this way, the consumer is able to identify the color to be dispensed into the toilet bowl and, at the same time, that different active ingredient preparations are present in the device.
  • One example in this regard is a blue receiving container, in which one toilet block part is blue and the other part is white.
  • the bearing plate is spaced in each case from the front wall and rear wall of the receiving container by a maximum distance of 3 mm. This applies in particular for toilet blocks that are higher than they are deep in the usage position. Due to the small distance between the front and rear walls, these are eroded less by the flushing water and can thus be kept longer in the usage position.
  • the bearing surface is a continuous surface. In this way, it is achieved that a minimum of residual water, or even no residual water, remains in the receiving container.
  • pan bottom prefferably has a low point and for the siphon to be arranged at the lowest point of the pan bottom.
  • the inlet opening of the siphon in which flushing water can flow from the receiving container into the siphon, to be located no more than 10 mm, further preferably no more than 5 mm, above the pan bottom.
  • the level of the inlet opening is defined by the distance between the siphon cover and the pan bottom, for example.
  • the siphon cover can have a tooth-like lower edge, for example. In this case, the distance between the upper tooth edge and the pan bottom can be taken into consideration.
  • the flushing water flows almost completely out of the pan due to capillary action. This is particularly favorable when the siphon is arranged at the lowest point of the pan bottom.
  • the toilet block is at least two-piece.
  • the parts of the toilet block can be joined to each other or be separate, preferably separate. In the usage position, the boundary between the two parts is located on the bearing plate. In this way, both parts are supported by the bearing plate.
  • both parts of the toilet block fulfill different functions, for example one cleaning part containing a cleaning composition and one water coloring part containing a dye composition.
  • FIG. 1 shows a perspective view of the device, the device being shown in the open state and without a toilet block;
  • FIG. 2 shows a sectional view through a device according to the invention along cutting plane A-A from FIG. 1 ;
  • FIG. 3 shows a sectional view through a device according to the invention, comprising a toilet block, along cutting plane B-B from FIG. 1 .
  • FIGS. 1 to 3 A device 1 according to the invention is shown in FIGS. 1 to 3 .
  • the device 1 comprises a receiving container 3 , which can be fastened to the rim of the toilet bowl by way of a bracket-shaped holder 10 , but the holder may also be designed differently.
  • the receiving container 3 comprises at least one inlet 6 and one outlet 7 for flushing water and is fluidically connected to the toilet bowl via the outlet 7 , wherein a siphon 8 is arranged upstream from the outlet 7 .
  • the siphon 8 defines a triggering threshold level 17 and a terminating threshold level 18 for flushing water in the interior of the receiving container 3 .
  • the triggering threshold level 17 determines the time at which flushing water starts to discharge through the siphon 8 from the interior of the receiving container 3
  • the terminating threshold level 18 determines the time at which flushing water stops from being discharged from the receiving container 3 .
  • the triggering threshold level 17 and the terminating threshold level 18 define a desired, regulated discharge of flushing water from the receiving container 3 .
  • the receiving container 3 forms a pan 4 having a pan bottom 5 , on which the siphon 8 is arranged.
  • the receiving container 3 accommodates the toilet block 2 comprising the active ingredient preparation 16 , see FIG. 3 . Flushing water, which can enter the receiving container via the inlet 6 , can flow across the toilet block 2 .
  • the toilet block 2 is held above the pan bottom 5 and moreover, according to the invention, above the terminating threshold level 18 . If the toilet block 2 is two-piece, it is preferred for the boundary 2 . 1 between the parts to be located on the bearing plate.
  • FIGS. 1 to 3 show that the bearing plate 9 forms part of the siphon 8 , and in the present case it is integrally formed on the siphon cover and thus delimits the flow duct 19 .
  • the bearing plate 9 has a bearing surface 9 . 1 larger than the cross-sectional surface of the outer pipe 8 . 1 of the siphon cover.
  • the toilet block is supported longer during use. This ensures that the dispensing of active ingredient preparation into the toilet bowl takes place constantly over an extended period of time.
  • the siphon cover, and thus the bearing plate at the same time, is placed onto the device using a simple production step.
