Definitions

  • This invention relates to a dispenser for liquid active substances (deodorants/cleansers/refreshers/disinfectants and the like) for a W.C. bowl.
  • EP 538957 describes a dispenser for a W.C. bowl comprising a bed of sponge material which is suspended below the bowl rim in a horizontal position, to be lapped by the flushing water flow, On this sponge bed a bottle containing liquid active substance is positioned inverted, with its mouth in contact with the sponge.
  • An object of this invention is to provide a device of the type to be housed within a W.C. bowl, comprising a closed bottle the interior of which contains active substance in the liquid state, and a support means for supporting said bottle, which is different from known devices and is able to overcome the drawbacks arising in the operation of known devices, and in particular is able to effect a sized, sufficiently regular and controlled delivery of the active substance from the bottle.
  • Another object is to provide a dispenser which is of simple low-cost manufacture.
  • Figure 1A is an enlarged detail of Figure 1.
  • Figure 2 is a schematic section through a second embodiment of the dispenser.
  • Figure 3 is a schematic section through a third embodiment of the dispenser.
  • the dispenser of the invention is of the type comprising a closed bottle 11 containing in its interior an active substance R in the liquid state, and a support means 50 to support said bottle 11 in the interior of the W.C. bowl.
  • the invention comprises, supported by the support means 50, a collection tray 15 for collecting water from the flushing flow in such a manner as to increase the water level in its interior, and a half-siphon 20 comprising an ascending leg 21 with an inlet 23 which draws water from the collection tray 15, and a longer descending leg 22 having an outlet 24 positioned at a lower level than the inlet 23, to discharge water to the outside of the collection tray 15.
  • a half-siphon 20 comprising an ascending leg 21 with an inlet 23 which draws water from the collection tray 15, and a longer descending leg 22 having an outlet 24 positioned at a lower level than the inlet 23, to discharge water to the outside of the collection tray 15.
  • the tray 15 which is positioned to encounter the water flow, collects water Q, the level of which hence increases in its interior.
  • this level reaches the level A the action of the half-siphon 20 is triggered, to draw water through the ascending leg 21 and discharge it to the outside of the tray along the descending leg 22; this action lasts until, the tray in the meantime having ceased to collect water (the flushing flow having terminated), the level in the tray 15 falls to the level B, corresponding to the inlet mouth 23, at which point the siphon action is deactivated.
  • the action of the half-siphon 20 is determined mainly by the geometrical characteristics of the dispenser, it remains quite constant for different types of W.C.s and for different flushing flow characteristics; in addition the suction action on the active substance R is much greater than the forces which under static conditions prevent the active substance from leaving the bottle, hence its extraction is influenced only slightly by these; the result is that the behaviour of the dispenser, in particular the exit of the active substance from the bottle, is very constant both with continuing use, and as the conditions under which it is used vary (arrangement of the dispenser on the basis of the geometry of the W.C. bowl, flow intensity), and with varying physical characteristics of the active substance R.
  • a member 41 for closing the bottle mouth 12 is advantageously provided which connects the mouth 12 to the half-siphon 20 via said sized conduit 26.
  • Said member 41 comprises a tube of vertical axis, the diameter of which is such that its outer lateral surface sealedly encircles the inner surface of the exit mouth 12, its bottom being closed by an end 42 communicating with the conduit 26.
  • Preferably its upper end is cut along an inclined plane to define a pointed element.
  • the bottle 11 is coupled to the tube 41 by making this penetrate its mouth 12, hence also breaking a diaphragm closing the mouth 12 before the bottle 11 engages the support means.
  • the ascending leg 21 of the half-siphon 20 is spaced from the descending leg and is connected to it by a curved upper portion 25 connected to the bottle 11.
  • This is disposed with its closed mouth 12 facing downwards and connected to the curved portion 24 by the conduit 26, the passageway through the conduit 26 and/or the aperture in the bottom 42 by which the conduit communicates with the mouth 12 defining said sized passage.
  • the bottle is disposed with its mouth 12 facing downwards and closed by the end 42, through which there is a sized passage 28 connecting the mouth of the bottle 11 to the suction region of the half-siphon 20.
  • the leg 22 is joined to the leg 21 by vertical fins 29.
  • the collection tray 15 possesses one or more drainage apertures 16 to discharge the water which collects in it, however at a decidedly lesser rate than that with which the water collects in its interior during the flushing flow, so that an increase in water level is still obtained for the aforesaid reasons.
  • the third embodiment, shown in Figure 3 differs from the preceding by comprising a cap 30 with its concavity facing downwards and enclosing the upper end portion of the half-siphon 20, which can be either of the type shown in Figure 1 or of the type shown in Figure 2.
  • the edge 31 of the lower mouth extends downwards within the collection chamber for a short distance below the level B of the inlet 23 of the half-siphon, the top of the interior of the cap 30 being connected, via a sized passage 32 provided in the end 42, to the bottom of the interior of the bottle 11.
  • the level in the tray 15 and in the cap 30 increases, and when this level reaches the level A the action of the half-siphon 20 is triggered, so that it draws water through the ascending leg 21 and discharges it to the outside of the tray; this action lasts until, the tray in the meantime having ceased to collect water, the level in the tray 15 falls to the level B, corresponding to the inlet mouth 23, at which point the siphon action is deactivated.
  • Another ventilation action also occurs when the level in the tray increases under the flushing flow, as the air which remains trapped in the cap is urged under slight pressure towards the bottle interior.
