Definitions

  • the present invention relates to a device for dispensing liquid substances inside toilet bowls.
  • a supporting element which is provided with means for engaging the toilet bowl rim and supports a container of the liquid substance to be dispensed; by means of appropriately provided passage ducts, said container allows the liquid substance to fall by gravity onto an element that is provided so as to retain a preset amount of the liquid substance and is exposed to the action of the toilet bowl cleaning water.
  • the element that retains the liquid substance is constituted by a porous mass; in other devices, it is constituted by a body with multiple channels or grooves, with a path that may optionally be labyrinth-like, so as to retain a preset amount of liquid substance, preventing it from dripping freely inside the toilet bowl.
  • the cleaning water is conveyed onto this element and entrains a preset amount of the liquid substance.
  • the aim of the present invention is to obviate the drawbacks cited above by providing a device for dispensing liquid substances inside toilet bowls that ensures, every time the flushing device of the toilet bowl is operated, a substantially constant release of the liquid substance into the cleaning water, regardless of the frequency of the activations of the toilet bowl flushing device.
  • an object of the invention is to provide a device that ensures a substantially constant release of the liquid substance into the toilet bowl cleaning water throughout its useful life.
  • Another object of the invention is to provide a device that can be manufactured at competitive costs.
  • a device for dispensing liquid substances inside toilet bowls comprising a supporting element that is provided with means for engaging the rim of a toilet bowl and forms at least one receptacle for at least one container of the liquid substance to be dispensed, said container being arranged so that its outlet is directed downwardly, characterized in that below or at the outlet of the container there is a perforated wall, which faces in an upward region an element for collecting the liquid substance dispensed from said container, said collecting element being affected by the passage of the toilet bowl cleaning water, the perforations of said perforated wall and the viscosity of the liquid substance dispensed from said container being adapted to form, on the lower face of said perforated wall, a suspended meniscus of liquid substance that contrasts the further outflow of liquid substance from said container and can be removed by the stream of toilet bowl cleaning water that flows over said collecting element.
  • the device according to the invention comprises a supporting element 2, which is provided with means for engaging a rim 3 of a toilet bowl 4 and forms at least one receptacle 5 for at least one container 6 for a liquid substance 20 to be dispensed, which is placed in the receptacle 5 so that its outlet 7 is directed downwardly.
  • the collecting element 9 is provided and arranged so that when the device is fastened to the rim 3 of the toilet bowl 4 it is struck by the flow of the water for cleaning the toilet bowl 4.
  • Perforations 10 of the perforated wall 8 and the viscosity of the liquid substance 20 dispensed from the container 6 are adapted to form, on the lower face of a perforated wall 8, a suspended meniscus of liquid 20a, which contrasts the further outflow of the liquid substance 20 from the container 6 and is reached and removed by the stream of water for cleaning the toilet bowl 4 that flows over the collecting element 9.
  • the perforated wall 8 is preferably provided as a grille and the perforations 10 are preferably shaped like funnels that taper downwardly.
  • the supporting element 2 is preferably made of a molded synthetic material, and the perforated wall 8 may be provided monolithically with the supporting element 2 on the bottom of the receptacle 5 that is designed to receive the container 6.
  • the container 6 is preferably made of a transparent or semitransparent molded synthetic material, so as to allow to view the level of the liquid substance 20 contained therein.
  • the outlet 7 of the container 6 may be closed until it is used by a cap 12 of the type with a pierceable diaphragm, and on the bottom of the receptacle 5, at the region where the outlet 7 of the container 6 is located, it is possible to provide a beveled element 13, which can be inserted in the outlet 7 in order to retain the container 6 and pierce the closure diaphragm provided on the outlet 7 of the container 6.
  • the perforated wall 8 may be provided directly on the outlet 7 of the container 6.
  • a closure cap or diaphragm it is possible to provide a closure cap or diaphragm to be removed before arranging the container 6 on the supporting element 2.
  • the beveled element 13 is obviously unnecessary.
  • the means for engaging the supporting element 2 with the rim 3 of the toilet bowl 4 are preferably constituted by a hook-like element 14, which is also preferably made of molded synthetic material and is connected to the supporting element 2 laterally to the receptacle 5 that receives the container 6.
  • the collecting element 9 is preferably tray-like, and has a wing 9a that protrudes laterally with respect to the container 6 and can be arranged below the rim 3 of the toilet bowl 4, so as to receive the cleaning water that is dispensed generally between the rim 3 and the inside walls of the toilet bowl 4.
  • the collecting element 9 has, on its upper face, grooves 15, which are designed to retain the liquid substance 20 dispensed from the container 6, as will become better apparent hereinafter.
  • the collecting element 9 is open on its opposite side with respect to the wing 9a, in order to allow the cleaning water to flow freely over its upper face.
  • the collecting element 9 further has drainage holes 16 to prevent stagnation of the cleaning water of the toilet bowl 4 on its upper face.
  • the collecting element 9 has, in the region below the outlet 7, i.e., in the region that faces the perforated wall 8, protrusions 17 that protrude toward the perforated wall 8.
  • Such protrusions 17 are designed to retain a certain amount of the liquid substance 20 dispensed from the container 6 and to facilitate turbulence of the cleaning water below the perforated wall 8, as will become better apparent hereinafter.
  • the collecting element 9 is preferably made of molded synthetic material and is connected to the supporting element 2 below the receptacle 5 that accommodates the container 6.
  • the diameter of the holes 10 of the perforated wall 8 is substantially comprised between 0.3 and 3 mm, and the liquid substance 20 contained in the container 6 preferably has a viscosity substantially comprised between 100 and 4000 cps.
  • the diameter of the holes 10 of the perforated wall 8 is substantially comprised between 0.5 and 1 mm, and the liquid substance 20 contained in the container 6 preferably has a viscosity substantially comprised between 2000 and 3000 cps.
  • the device with the container 6 arranged upside down, i.e., so that its outlet 7 is directed downwardly inside the receptacle 5 of the supporting element 2, is engaged, by means of the hook-like element 15, on the rim 3 of the toilet bowl 4, so that the wing 9a of the collecting element 9 can receive the cleaning water of the toilet bowl 4 when the flushing device of said toilet bowl 4 is operated.
  • a few drops of the liquid substance 20 fall onto the collecting element 9 and are retained on said collecting element by the presence of the protrusions 17 and of the grooves 15.
  • the drops of liquid substance 20 that remain on the collecting element 9 may perform a fragrancing action if the liquid substance 20 has fragrances added thereto.
  • the cleaning water flows over the collecting element 9, between the upper face thereof and the perforated wall 8, also striking the perforated wall 8 and removing the liquid substance 20 that had deposited on the upper face of the collecting element and the meniscus 20a of liquid substance 20 that had formed on the lower face of the perforated wall 8.
  • the protrusions 17 facilitate turbulence of the cleaning water below the perforated wall 8, which ensures removal of the meniscus 20a of the liquid substance 20 that has formed on the lower face of the perforated wall 8.
  • the container 6 is transparent or semitransparent, the user can check visually the level of the liquid substance, and when the container is empty he can replace the container 6 with a full one or fill it.
  • the device according to the invention may carry, instead of a single container 6, two side-by-side containers of liquid substances, providing a perforated wall 8 as described at or below the outlet of each container. In this manner, it is possible to achieve simultaneous dispensing of two liquid substances in the cleaning water of the toilet bowl.
  • the device according to the invention fully achieves the intended aim, since it ensures the dispensing, at each actuation of the toilet bowl flushing device, of substantially constant amounts of liquid substance regardless of the degree of filling of the container of the liquid substance and of the frequency with which the flushing device is operated.
  • the materials used may be any according to requirements and to the state of the art.
