  • Such an installation also ensures that water, when flushed from the toilet, is in the path of flushing water and thereby enters the first chamber 105 through the water inlet opening 150 wherein it contacts the treatment agent 120 before passing out from the first chamber through an outlet opening and into a second chamber, which has at least one device outlet opening 170 as illustrated on Figure 1 .
  • Figure 2 illustrates a frontal, planar view of the ITB device of Figure 1 , albeit with the omission of the hanger 160.
  • the treatment agent 120 occupies a significant amount of the first chamber volume.

  • a device outlet opening 170 which however is depicted in dotted line format as it is not normally visible through the roof 140 of the second chamber.
  • water entering the first chamber of the device necessarily must contact the treatment agent and thus form a treatment composition, before exiting the first chamber via the outlet opening 185, and then into the second chamber before ultimately exiting the device via the device outlet opening.
  • the amount or residence time is a key to ensuring that effective concentrations of a treatment agent are combined with the flush water passing through the device and forming the treatment composition.
  • a disinfecting agent such as a bleach or a quaternary ammonium compound is to be eluted and provided to the toilet bowl.
  • Increasing the residence time in the device typically also increases the ultimate concentration of a treatment agent in the treatment composition provided to the toilet bowl.
  • first and second chambers and particularly their respective volumes Careful selection of the relative dimensions of the first and second chambers and particularly their respective volumes, as well as for the size and number of outlet opening(s) between the first and second chambers, as well as the size and number of device outlet opening(s) will permit for the production of an ITB device 100 which has a long residence time of the flush water contacting the treatment agent, as well as a longer or delayed delivery period of the delivery of the treatment composition to the toilet bowl following the flush of the toilet bowl.
  • the various dimensions of the first and second chambers can be varied to adjust the residence time of the flush water in the first chamber and/or to adjust the rate of delivery of the treatment composition. Additionally or alternately the residence time of the flush water in the first chamber can be increased by reducing the cross-sectional area or diameter of the outlet opening 185.
  • the rate of delivery of the treatment composition can be slowed or delayed by reducing the cross-sectional area or diameter of the device outlet opening 170.
  • increasing and/or decreasing the volumes of the first fill chamber, and of the second fill chamber may also be used to vary the flowrate of the treatment composition exiting the device. For example wherein a long delay may be desired after the flush of water in the toilet, but prior to release of treatment composition into the toilet bowl, the respective volumes of the of the first chamber, and the second chamber is about may be reduced, such as to about 20-5:1.
  • the larger volume of the second chamber permits for a longer residence time of the treatment composition in the second chamber particularly in the instance wherein the device outlet opening is relocated to a position other than at the bottom or lowest portion of the second chamber. This effect can be increased also by reducing the cross-sectional area or diameter of the outlet opening 185 which would delay the rate of filling of the second chamber by the treatment composition entering from the first chamber.

  • the raised rib(s) extend into the interior of the first chamber containing the treatment agent.
  • the incorporation of one or more raised ribs 235 adds to the stiffness of the cover 230, and when used in an device wherein the outlet opening between the first and second chambers is adjacent to the cover, the presence of the one or more raised ribs 235 minimizes the likelihood that the treatment agent, particularly when in solid or "block” form does not obscure the outlet opening between the first and second chambers and deny passage of the treatment composition from the first chamber and into the second chamber of the device.
  • cover 230 depicted on Figure 6 may be used with any embodiment of the invention.
