Definitions

  • a bacteriostatic agent is a substance that retards the life processes of the bacteria and although it does not kill them instantly through continuous inhibition, it will eventually result in death for the bacteria.
  • cosmetic toiletries have been made with water insoluble plastic or plastic derivative containers which when placed in the water tank of the toilet release a liquid or water soluble substance containing one or more of the aforementioned agents.
  • the substance is generally colored employing one of the many commercially available dyes and upon exhaustion of the agents in the container, indicated by absence of color in the fluid, the water insoluble plastic or plastic derivative container is re moved from the toilet tank and discarded.
  • This invention has for an object the production of a toilet element which does not contain any water insoluble part or component thereof, is not suspended in the water tank by any hanging part and usually is not visible.
  • a related object is to provide a completely water soluble entity containing the active ingredients dispersed, embedded, suspended or emulsed in the water sensitive, water soluble or water swellable binding agent.
  • a further object of the invention is to provide an inexpensive and long lasting toilet article for the consumer.
  • the novel object of the invention is that it is totally independent of water pressure in the tank or the water level (the amount of the water) in the tank.
  • the central object of the invention is to provide a water soluble toilet element containing therein bacteriostatic and/or deodorizing and/or coloring agents and is active only when contacted with water and is adapted to be placed in such a position in the toilet that such contact occurs only during the flushing of water whereby the norinal mechanical and structural components of the toilet open to allow such contact with water and at the completion of the flushing cycle the mechanical and structural components mechanically close to disallow further contact of the element with water.
  • a toilet element or article containing (1) a water sensitive, water soluble or water swellable binding agent, (2) a bacteriostatic and/or deodorizing and/or coloring ingredients dispersed, embedded, suspended, or emulsed within the water sensitive, water soluble or water swellable binding agent and (3) dispersants, antioxidants, plasticizers, stabilizers, hardeners, soaps and/or detergents, fillers, water and/or organic solvents and other processing and supportive agents; which toilet element when placed in such a location in the toilet unit is exposed to water only when the toilet is flushed and is automatically isolated or partially isolated from the water when the unit is not operational. Further the unit is not dependent on water pressure or amount of water in the tank.
  • the toilet element is placed in the upper portion of the drain aperture in the tank which receives the inflow of water from the float valve through a rubber or plastic tube and drains directly into the main drain below the tank proper, circumventing the water in the tank when the toilet is flushed and is isolated or semi-isolated from the water when the float valve is closed at the end of the flushing cycle.
  • This process allows enough of the element to be dissolved and carried directly into the toilet bowl (as opposed to being dissolved in the tank) where the action of the active ingredients are mostly needed.
  • the element of this invention is effective until completely dissolved as indicated by the absence of color in the toilet bowl water and a fresh element inserted in the aforesaid location to repeat the process.
  • FIG. 1 is an elevational view with portions in section of a toilet employing the device of the present invention. Description of the Preferred Embodiment Other features and advantages of the present invention will be made more apparent as this description proceeds.
  • the element indicated generally by reference numeral 10(a) and 10(b) is preferably placed in the aperture of the upright portion of the drain tube 11 located near the center of the bottom of the toilet tank 12 and connected to the main drain tube 13 via a small opening 14 below the plastic or rubber closure cup 15.
  • the element is activated by a series of related actions initiated by depressing the handle 16, lifting horizontal bar 17 which is connected by vertical chain 18 to the partially rotating unit 19 attached to rubber or plastic cup 15, elevating the cup 15 from its sealant position over an aperture of main drain tube 13 allowing water from tank 12 to flow into the bowl 20 through small openings 21 located around the circumference of the bowl rim 22 and to thereby remove the contents of the bowl through the sewage drain 23.
  • float valve 24 opens to allow a flow of water through the small rubber or plastic tube 25 into the upright drain tube 11 and into the main drain 13.
  • This action of the float valve is initiated by lowering the water level in the tank which in turn lowers the floating ball 26 connected to the floating valve 24 via the float rod 27 until the process is reversed when the cycle is completed and the float ball 26 is raised by the increase of volume of water in the tank until the water level reaches a desired measure in the tank, shutting off the inflow of water through the float valve 24 into the upright drain tube 11 wherein the toilet element 10a is positioned.
  • the element 10 of this invention may be positioned in the upright tube 11 as shown at 10a, preferably, or it may be located in the main drain 13 as shown at 10b which in either case is not directly connected to the water in the tank proper. It functions completely apart from the water in the tank.
  • a small plastic or wire mesh filtering basket 44 of proper diameter may be placed either in the upright tube 11 or in the main drain tube 13 and left in position after the initial placement.
  • the basket 44 may have small apertures in its entire circumference, or part of, to facilitate the escape of water into the toilet bowl. The rate of dissolution of the toilet element 10 in the water is dependent on certain factors of which some are:
  • the toilet element 10 may be made to last from about 10 flushing cycles and up to, but not limited to, about 1,000 cycles by simply altering one or more of the above factors.
