Definitions

  • This invention relates to devices for dissolving and dispensing a solid and for controlling the rate of flow of the solid in solution in a dispersed manner into a toilet tank or bowl.
  • U.S. Patent No. 3,781,926 to Levey discloses just such a device.
  • the Levey patent discloses a cap which is usable with a container with the container filled with a water soluble compound.
  • the cap includes an inner and outer shell having orifices at certain locations and the shells are positioned, with respect to each, so as to allow a specified quantity of dissolved solid to flow from the container for every flushing of the tank.
  • the device of Levey however, is not shaped so as to take advantage of the various turbulent flows generated in a tank during flushing and thus, dispersion of the solution into the tank is not as rapid, controlled and efficient as might be desired. Further, the Levey device has a complicated construction and is therefore expensive to manufacture
  • a dispersing dispensing cap for use in a toilet tank in combination with a container which contains soluble solid material, said cap comprising a cylindrical body having a hollow interior and an open bottom a generally conical portion integral with said cylindrical body at the top of said body, said conical portion extending into said hollow interior with the vertex thereof extending downwardly into said interior, and engaging means for supporting and holding said cylindrical body on the container, said conical portion having openings which are laterally spaced from each other along the wall of said conical portion and a hole at the vertex of said conical portion, for guiding fluid into and out of the container.
  • a dispersing dispenser for use in a toilet tank, said dispenser comprising a container for containing soluble solid material, and a cap for fitting to said container, said cap comprising a cylindrical body having a hollow interior and an open bottom, a conical portion integral with said cylindrical body at the top of said body, said conical portion extending into said hollow interior with the vertex thereof extending downwardly into said interior, and engaging means for supporting and holding said cap on said container, said conical portion having openings which are laterally spaced from each other along the wall of said conical portion and a hole at the vertex of said conical portion, for guiding fluid into said container.
  • the present invention may be used to provide a solution dispenser for a toilet which is simple in construction and costs little to manufacture, yet effectively dispenses and disperses specified quantities of a solution into a toilet tank.
  • the invention may also be used to provide a solution dispenser which can be employed with a variety of soluble solid containing containers.
  • the dispensing dispersion control cap shown in Fig. 1 is generally assignated 1 and includes an inwardly and downwardly extending conical portion 3 which has a plurality of openings 5 or 5' in the wall thereof.
  • the cap 1 also includes a circular hole 7 at the lowermost portion or vertex 9 of the conical portion 3.
  • the entire cap is molded as a one piece unit from flexible plastic, and is therefore simple and inexpensive to make and virtually unbreakable.
  • flexible plastic allows for the cap 1 to be fitted securely on a variety of soluble solid containing containers. Further, the fact that it is made of a flexible plastic allows for a tight seal to be maintained at the region where the cap 1 and the container meet.
  • the cap 1 has an inwardly extending protuberance 21 which is received in a groove 19 on the top of the container for securely fastening the cap 1 to the container.
  • the conical portion 3 of the cap 1 has a vertex 9 as shown in Fig. 3 and Fig. 7.
  • the vertex tapers into an almost straight vertical drop at the lowermost portion so as to define a substantially vertically extending tube.
  • the openings 5 are rectangular in shape and are longer in the length-wise direction, or in the direction extending from the top of the cap 1 to the vertex 9.
  • the openings 5' may have an oval shape.
  • the oval openings 5' are used when mold manufacturing, techniques are used to produce the device.
  • the openings can be of any shape, size or number desired, and all of these factors are determined by the rate at which it is desired to dispense water soluble material from the container.
  • rib-like projections 13 extending inwardly from the inner side wall 15 of the cap 1. These projections 13 serve to support the cap 1 in a stable manner on the container 11 as can be seen from Fig. 3 and Fig 7. These serve to keep the cap from slipping too far over the container. Further, any conventional engaging means can also be used to perform this function and to hold the cap on the container.
  • the cap 1 also includes an upwardly extending ridge 17 at the top of the conical portion 3 which serves to engage a childproof cap as shown in Fig. 5 and disclosed in U.S. Patent No. 4,000,839.
  • a cap 1 which is constructed as described above, is disposed on the floor of a toilet tank.
  • Fig. 3 and Fig. 7 show the various flows occurring in the device of the present invention.
  • the water in region A serves to dissolve the soluble chemical solid thereinto. While this is occurring, there results different concentrations of the solution and thus, a gravity induced flow or circulation will be created. More particularly, the lesser concentrated quantities of solution will flow out through the openings 5 or 5' which can be, but are not required to be equally laterally spaced from each other and, because of the conical design of the cap 1, will rest or be held in region B as defined by the conical portion 3.
  • the solution which is resting within the conical portion 3 is of a desired concentration which is determined according to the size of the cap and slots used.
  • the solution contained in the conical portion 3 is easily drawn off during the change in outside fluid level and is dispersed throughout the tank. Further, the turbulence also serves to mix the next dose which is then trapped, as described previously, in the conical portion 3.
  • the openings 5 or 5' regulate the quantity of soluble solid which enters solution and is dispensed from the container for subsequent dispersion from the region B.
  • the hole 7 at the lower part of the conical portion 3 serves to direct the water flow from region C into region A for mixing.
  • the newly prepared solution having the appropriate concentration then flows, in large part, although not totally, through openings 5 or 5', into conical portion 3 and readies itself for dispersion while preventing massive, or highly concentrated, doses from being dispensed during either chemical or mechanical activity.
