Suspended dissoluble disinfectant container

Claim 2

In a system for dispensing chemicals in the water tank of a water closet, said water tank being filled and drained periodically to and from a full level; a closed container constructed of water impervious material with thin flexible thermoplastic side walls and having a pair of apertures spaced one below the other aperture through one of said side walls; means for suspending said container in said tank with said aperture at a level which is at least partially below said full level; a quantity of said chemicals partially filling said container; a thin, flexible water soluble strip adhesively secured to and flexibly conforming with said one side wall and closing the upper of said aperture, and water soluble means covering the lower of said apertures, both said water soluble strip and water soluble means sealing interior portions of the container until said strip is submerged in the water in said tank, said water dissolving said strip to open said aperture and admit said water into said container to dissolve a portion of said chemicals and cause said dissolved chemicals to flow into said water in said tank and be dispensed by said tank when said tank is periodically drained.

Claim 3

Apparatus for storing and dispensing water soluble chemicals in a periodically drained water tank, comprising: a watertight envelope containing a quantity of soluble chemicals constructed of flexible plastic sheet material and having a pair of opposing sidewalls having peripheral edges, said edges of one of said sidewalls being sealed to said edges of the other of said side walls to form a peripheral fringe portion along the entire periphery of said envelope which resides in an effectively single plane and has a thickness twice that of either of said sidewalls whereby said fringe portion is effectively twice as rigid as said flexible sidewalls, each of said sidewalls having a surface area greater than the planar area peripherally surrounded by said peripheral fringe portion whereby said sidewalls bulge outwaRdly to define an interior chamber for containing such chemicals; a pair of apertures through one of said side walls said apertures being vertically spaced relative to each other and communicating between said chamber and the interior of said envelope with a vertical slit in said one sidewall extending between said apertures for tending to prevent development of an air lock in said chamber, a flexible thin water soluble strip covering said apertures and slit to seal said chemicals in said chamber until said envelope is immersed in water in said tank; and means provided in said fringe portion at said one end for suspending said envelope in said tank with said pair of apertures positioned below the level of the water within said tank when said tank is filled.

Claim 4

Apparatus for storing and dispensing water soluble chemicals in a periodically drained water tank, comprising: a watertight envelope containing a quantity of soluble chemicals constructed of flexible plastic sheet material and having a pair of opposing sidewalls having peripheral edges, said edges of one of said sidewalls being sealed to said edges of the other of said side walls to form a peripheral fringe portion along the entire periphery of said envelope which resides in an effectively single plane and has a thickness twice that of either of said sidewalls whereby said fringe portion is effectively twice as rigid as said flexible sidewalls, each of said sidewalls having a surface area greater than the planar area peripherally surrounded by said peripheral fringe portion whereby said sidewalls bulge outwaRdly to define an interior chamber for containing such chemicals; a pair of apertures through one of said side walls said apertures being vertically spaced relative to each other and communicating between said chamber and the interior of said envelope with a vertical slit in said one sidewall extending between said apertures for tending to prevent development of an air lock in said chamber, a flexible thin water soluble strip covering said apertures and slit to seal said chemicals in said chamber until said envelope is immersed in water in said tank; and means provided in said fringe portion at said one end for suspending said envelope in said tank with said pair of apertures positioned below the level of the water within said tank when said tank is filled.

Claim 5

Apparatus according to claim 2, wherein said this flexible water soluble strip is adhesively secured to and flexibly conforming with said one sidewall to close said apertures and said vertical slit.
