Definitions

  • the present invention relates to methods and apparatus for packaging, and more particularly to packaging for products used to clean, remove limescale, disinfect, deodorize, add color and/or add fragrance and add/or impart foam to toilet bowls.
  • Both commercial and residential toilets often use treated water for several purposes.
  • the water is treated to provide disinfectant, anti-bacterial, anti-odor and other useful properties that make the toilet “self-cleaning" to the extent that situations such as the proliferation of mold, slime, calcium or lime deposits and iron oxide stains are diminished, and so that the bowl is as clean as possible after each use from the turbulent action of the flush cycle alone.
  • the water is often treated to add color and fragrance, both of which improve the aesthetics of the toilet and the room.
  • a fragrance is any molecule that diffuses via vaporization into the atmosphere (under local conditions of temperature and pressure) and subsequently activates a specific receptor in the nasal cavity. The fragrance may either mask any unpleasant odor or may simply be an environmental improvement or a combination of these.
  • Toilet water treatment systems fall into two broad categories, i.e., those that treat the water in the tank, and those that treat the water in the bowl.
  • Systems operating within the tank range from solid "drop in” tablets to more elaborate systems such as that shown in U.S. Patent No. 6,192,524, Black, which discloses a system that is affixed to the overflow drain tube found in toilet tanks.
  • commercial toilets and many newer residential toilets are either tankless or have a significantly reduced tank volume or non/ difficult accessible tanks. Therefore, a system that is attached to the toilet bowl itself is ultimately of wider applicability.
  • an apparatus for introducing material into a toilet bowl that has a rim holder positioned within the toilet bowl and a material container filled with a material along with a material dispenser connecting the rim holder and a vessel section of the material container, such that the vessel section comprises walls and a lower aperture open to the toilet bowl.
  • this apparatus fills the vessel section to a predetermined level causing the material to be dispensed into the vessel section.
  • the rim holder and vessel section are integral, and in certain embodiments, the rim holder further comprises a hanger.
  • the apparatus is preferably molded from a plastic material and the material preferably comprises at least one active component.
  • the material is at least one material selected from the group comprising a fragrance, a disinfectant, a coloring agent, and a cleaner.
  • the present invention also discloses methods of adding a material to a toilet bowl by positioning a rim holder within the toilet bowl, positioning a material container in fluid communication with the rim holder, and then diverting a portion of flush water entering the toilet bowl into a vessel section.
  • Material is mixed with the water in the vessel section and a mixture including the material flows into the toilet bowl via a lower aperture in the vessel section after an initial volume of flush water has exited the toilet bowl.
  • the mixing takes place when a predetermined level within the vessel section is reached, and the flow through the lower aperture is metered so that substantially all the liquid within the vessel section is dispensed into the bowl after a flush cycle is substantially competed.
  • the material added is at least one material selected from the group comprising a fragrance, a disinfectant, a coloring agent, and a cleaner.
  • the present invention therefore discloses, in preferred embodiments, apparatus for dispensing a material into a toilet bowl that has a rim holder with a hanger portion that engages the toilet bowl, a vessel section that holds a volume of flush water, a lower aperture that drains the vessel section; and a material container received by the vessel section, whereby material is admitted to the vessel section after a predetermined level of flush water fills the vessel section.
  • the rim holder and the material container are molded from plastic and the material is at least one material selected from the group comprising a fragrance, a disinfectant, a coloring agent, and a cleaner.
  • FIG. 1 there is shown a perspective view of a preferred embodiment 100 of the present invention in which a material container 110 is inserted into a rim holder 120. Further details of this embodiment can be seen with reference to FIG. 2, which is an exploded perspective view of the assembly illustrated in FIG. 1.
  • the entire assembly 100 will be sold as a disposable assembly, while in other embodiments, the material container 110 will be sold independently for replacement in an existing rim holder 120.
  • the rim holder 120 may be made of any of a number of materials, primarily molded polymers, however, alternative materials include metals, fiber composite materials and ceramics.
  • the material container 110 may be formed from a molded polymer, glass or ceramic or other material.
  • the choice will take into consideration the nature of the liquid being held inside and chosen so as to minimize degradation of the nature of the liquid, e.g., the preservation of fragrance strength, cleansing and disinfectant power, and color stability.
  • the material container can be divided into a plurality of chambers if desired so that multiple materials can be provided. This is desirable if the materials to be dispensed are not compatible, which not uncommon when a bleach material is used.
  • the material container 110 provides a housing for at least one material "M” that is to be admitted to the water that is to remain in a toilet bowl.
  • the material may include a cleaner, a disinfectant, a fragrance or a colorant, or any combination of such materials, all of which are well known, either alone or in various combinations. Additionally, the material may be provided in solid, gel, particle, liquid or any combination of forms so long as the material in the material housing 110 is water-soluble. It should be noted that although the discussions herein relate to toilets that use water, it should be understood that the concepts of the present invention have equal applicability to "chemical" toilets that use a medium other than water. When flushed, such embodiments will provide the same mechanism of action as described below, except that the toilet bowl is not filled with water, and the material "M" will be soluble in whatever chemical flushing agent the toilet uses.
  • FIG. 3 An elevation cross-sectional view of an apparatus made in accordance with the present invention affixed to a toilet bowl is shown in FIG. 3.
  • a hanger portion 122 of the rim holder 120 extends over and engages the rim of the toilet bowl 50 in a manner known in the art.
  • the material chosen for the hanger portion will provide sufficient strength, flexibility and resilience to accommodate this function.
  • the geometry of the hanger 122 is chosen so that the assembly 100 is disposed below the top of the rim 52, and partially underneath the lower edge of the rim 54, as illustrated.
  • FIG. 3 Also shown in FIG. 3 is an approximation of the water flow in a flushed toilet, shown by the arrows. Upon flushing, water flows from the lower edge of the rim 54, and due to the construction of the rim holder 120, a portion of this flow is captured in the vessel section 124 of the rim holder 120.
  • FIG. 4 there is illustrated a view similar to that of FIG. 3, the primary difference being that the water flow from the flushing action of the toilet has substantially filled the vessel section 124.
  • the view of FIG. 4 is at a later time in the flushing cycle than the view shown in FIG. 3.
  • the water level "L” has risen so that material "M” held in the material container 110 is now mixed with the water in the vessel section 124, and this mixture is released into the toilet bowl from a lower aperture 126, as shown by the arrow in FIG. 4.
  • the size and structure of the vessel section will be designed to create a mixture of material and fresh water that is sufficient for the intended purpose, whether cleansing, fragrance, deodorizing, disinfecting, color, or any combination of these functions.
  • the material dispenser 128, which causes the material "M” to be mixed with the water in the vessel section 124.
  • the material dispenser 128 can be a simple wick or tube, a section of permeable material, such as a sponge or foam, in such embodiments, when the water captured in the vessel section 124 rises to a predetermined level, the material "M” is in contact with the water and fills the vessel section with a solution of water and the material.
  • the material dispenser 128 is a somewhat more complex mechanism, e.g., a valve with a float actuation such that the valve opens when the level within the vessel section 124 rises to a sufficient level.
  • the material dispenser 128 may be part of the material container 110, part of the rim holder 120, or a separate component that cooperates with of the main components.
  • the function required is that the material "M” is admitted into and mixed with the water only upon a sufficient level "L" in the vessel section 124, that in turn correlates to a predetermined time into the flush cycle.
  • the aperture 126 is designed to permit liquid to escape at a slower rate than it is admitted, the filled vessel section 124 will continue to be drained after the flush cycle is complete, and as a result, the solution of water and material "M” will be introduced into the bowl at a higher concentration with substantially less waste and greater effectiveness than found in prior art designs.
  • the device 100 described above enables a material, for one example a fragrance liquid, to be dispensed into a toilet bowl 50 both during and after the flushing cycle.
  • a material for one example a fragrance liquid
  • the present invention provides a significant improvement over the prior art in that previously treated liquid was flushed away since it was created either before or during the flush cycle, in some instances resulting in the majority of the liquid being flushed out of the bowl.
  • a device made in accordance with the present invention will provide a system wherein the material, whether a cleaner, disinfectant, colorant, fragrance, etc. remains substantially in the water remaining in the toilet bowl after the flush cycle has ended.
  • surfactant materials can be used in the present invention.
  • Representative surfactants include alkylaryl sulfonates, amine oxides, betaines, block copolymers, ethoxylated alcohols such as Neoldol 23 available from Shell Chemical Company, alkylphenol ethoxylates, ethoxylated fatty acids, fluorosurfactants, imididazolines and derivatives, quaternary amines, linear alkyl sulfonates, sulfosuccinates and alkyl polyglycosides as set forth in U.S. Patents, 3,970,596, 4,861,511 and 5,256,328.
  • Disinfectant materials used in the invention include alkyl dimethyl ammonium chloride, and orthophenylphenol.
  • a bacteriostatic such as 5-chloro-2-(2,4-dichlorophenoxy)phenol as described in U.S. Patent 3,897,357 is appropriate for use in toilet bowl cleanser applications.
  • Suitable thickening agents used in this field include fumed silica, methyl cellulose derivatives, clays, polyacrylic acid, xantham gums, polysaccharides and magnesium silicate.
  • Chelating agents suitable for use in the invention include tetrasodium EDTA.
  • Fragrance materials used in the invention include any material which is compatible with the other components in the composition and which imparts a pleasing asethically appealing fragrance to the composition.
  • fragrance materials When fragrance materials are used they are used in amounts up to about 15 weight percent, preferably from about 0.5 to 10 and most preferably from about 1 to about 5 weight percent based on the total weight of the composition.
  • Suitable fragrances include but are not limited to fruits such as almond, apple, cherry, grape, pear, pineapple, orange, strawberry, raspberry; musk, flower scents such as lavender-like, rose-like, iris-like, and carnation-like.
  • Other pleasant scents include herbal and woodland scents derived from pine, spruce and other forest smells.
  • Fragrances may also be derived from various oils, such as essential oils, or from plant materials such as peppermint, spearmint and the like.
  • fragrances A list of suitable fragrances is provided in U.S. Patent No. 4,534,891. Another source of suitable fragrances is found in Perfumes, Cosmetics and Soaps , Second Edition, edited by W. A. Poucher, 1959.
  • the fragrances provided in this treatise are acacia, cassie, chypre, cyclamen, fern, gardenia, hawthorn, heliotrope, honeysuckle, hyacinth, jasmine, lilac, lily, magnolia, mimosa, narcissus, freshly-cut hay, orange blossom, orchid, reseda, sweet pea, trefle, tuberose, vanilla, violet, wallflower, and the like.
