Definitions
- the bodies preferably include a solid cleaning and/or sanitizing material which will dissolve in part with each flow of drain or flush water thereby to provide automatic and metered cleaning, disinfecting, deodorizing, and the like, of the urinal.
- the solidcleaning and -sanitizing material most useful for urinals is most advantageously in bar or premolded form and comprises, as its essential active ingredients, an intimate admixture of (a) one or more synthetic detergents which are solid at room temperatures, and (b) an acidic agent in the form of one or more acids or acid-forming salts or both, the ratio of the synthetic detergent to the acidic agent in the solid, sanitizing material ranging preferably from about 1 to 100 of the former to about 1 of the latter.
- the bodies include a holder, which can be placed in a urinal drain or the like, designed to be made economically and to support the cleaning and sanitizing material in a position where drain or flush water will come into direct and extensive contact therewith.
- Urinals and the like require constant care to prevent the buildup of unsightly deposits, both organic and inorganic in origin, to reduce odors and to keep bacteria growth at minimally safe levels.
- products such, for example, as paradichlorobenzene, usually in cake form, have been widely used.
- Paradichlorobenzene cakes functionprimarily as odor maskants, and, while in certain instances, other ingredients such as disinfectants are incorporated in the cakes, they provide no cleansing or descaling action and afford no protection against buildup of undesirable deposits, stains, and encrustations common to sanitary units of the type here under consideration.
- the only effective method of overcoming the problems encountered with such sanitary units is daily, manual swabbing with, for example, standard powder or granular sanitizing agents.
- cleaning and sanitizing units including water dissolvable cleaning and sanitizing material preferably in the form of solid bars held in' a holder mountable in relation to'a urinal, drain or the like to enable drain or flush water to come directly into contact with a sufficient portion of cleaning and sanitizing material to dissolve a small but sufficient amount thereof effectively to carry on the cleaning and sanitizing functions required.
- the bars of cleaning and sanitizing material most advantageously contain, as essential active ingredients, an intimate admixture of (a) one or more synthetic detergents of the nonionic, cationic or amphoteric type, or mixtures thereof, which, preferably, are solid at room temperature, and (b) an acidic or hydrogen ion furnishing agent in the form of one or more acids or acid-forming salts or both.
- an intimate admixture of (a) one or more synthetic detergents of the nonionic, cationic or amphoteric type, or mixtures thereof, which, preferably, are solid at room temperature, and (b) an acidic or hydrogen ion furnishing agent in the form of one or more acids or acid-forming salts or both.
- the term "acidic agent” is intended to encompass both acids and acid-forming salts, and compatible mixtures thereof, having utility in the practice of the present invention.
- acid-forming salt as used herein is intended to include salts which in the presence of water are acid reacting or are capable of forming an
- the solid-cleaning and sanitizing material upon contact with drain or flush water, is dissolved in part thereby automatically metering into the water with each use of the sanitary unit a quantity of active ingredients capable of effectively cleansing, deodorizing, destaining, degerming, and removing inorganic and organic deposits and encrustations not only in the urinal unit itself but in the drain conduits associated with the unit.
- the present invention provided means for overcoming all of the daily sanitation problems encountered with urinals, drains and the like, without the need of frequent attention by maintenance personnel.
- the active ingredients of the cleaning and sanitizing material preferably used in this invention while capable in themselves of providing the cleansing and other action mentioned, can, as will be described hereafter in detail, incorporate other agents which serve to enhance, augment and complement the action of the active ingredients thereof.
- the cleaning and/or sanitizing unit of the invention used for urinals most advantageously includes a holder for a bar of cleaning and sanitizing material which holder comprises a basketlike assembly which fits over the urinal drain and has a cover portion and a base portion for holding a bar of the solidcleaning and sanitizing material.
- the base portion of the assembly extends outwardly beyond the cover portion and has a flexible annular outer lip which conforms to the walls of the urinal thereby preventing solid foreign matter and refuse from getting beneath the assembly blocking the drain.
- the base and cover portion of the holder are apertured so that splashing of urine is minimized and flush water gains ready access to the cleaning and sanitizing material whereby with each flushing a portion of the solidsanitizing material will be dissolved and released into the urinal.
- Thev nonionic, cationic, and amphoteric synthetic detergents having the greatest utility with the present invention form a wide group.
- the detergents used advantageously are solid at room temperatures and should be soluble, or at least partly soluble, in cold water.
- Exemplary of nonionic synthetic detergents useful in the formation of the solid sanitizing materials of the invention are ethylene oxide adducts of straight chain fatty acids, long chain fatty acid alkanolamides, ethylene oxide adducts of long chain fatty acid alkanolamides, fatty acid dialkyl amine oxides, and the like.
- amphoteric synthetic detergents having utility in the practice of this invention are the sodium salts of higher fatty acid amine propionates suchas disodium N-lauryl betaiminodipropionate, the disodium salt of N-tallow beta-amino dipropionate, the sodium salt of N-coco beta-amino propionate, and the like,.
- coconut oil fatty acid alkonolamides particularly coconut oil fatty acid or lauric or myristic acid amides of monoethanolamine and of diethanolamine are preferred.
- cationic synthetic detergents long chain fatty acid, especially C -C, fatty acid, quaternary imidazonlinates are preferable.
- amphoteric synthetic detergents the product sold under the trademark Deriphat 151" (General Mills, Inc.), a sodium salt of N-coco beta-amino propionate, is preferred.
- the synthetic detergents act not only as cleansing and lime soap dispersing agents, but especially in the case of the cationic detergents, also function as bactericidal and/or bacteriostatic agents when released by the flush water.
- the synthetic detergents in certain instances, provide an abrasive or scrubbing action in the flush water due to the fact that not all of the detergent dislodged in the flushing action goes into solution.
- the nondissolved crystals of the detergent thus serve as minute scrubbers or abraders as they are propelled around the sanitary unit by the flush water.
- the acidic agents utilized in the cleaning and sanitizing materials preferably used with this invention also may be selected from a wide group. Include in this group are mineral acids such as phosphoric acids, notably orthophosphoric acid, hydrochloric acid, boric acid, orthoboric acid, perchloric acid, sulfuric acid, and the like; organic acids exemplified by citric acid, acetic acid, cresotinic acid, and the like; and acidforming salts such as monosodium phosphate, sodium bisulfate, and the like; and compatible mixtures thereof.
- phosphoric acids notably orthophosphoric acid, hydrochloric acid, boric acid, orthoboric acid, perchloric acid, sulfuric acid, and the like
- organic acids exemplified by citric acid, acetic acid, cresotinic acid, and the like
- acidforming salts such as monosodium phosphate, sodium bisulfate
- orthophosphoric acid for example, readily removes hard water scale, adhering organic matter, and dissolves uric acid crystal deposits. in addition, it acts as a disinfectant and a deodorizer.
- Citric acid on the other hand, is an excellent sequestering and chelating agent, and acts to shipment.
- Citric acid Ethylenediaminc tetraacetic acid combine with iron, calcium, magnesium and other metal ions present in the flush water to form soluble salts thereby preventing buildup of mineral salt deposits in-the sanitary unit and the drain conduits associated with it.
- Various of the acids also exhibit bacteriacidal and/or bacteriostatic effects which are helpful in eliminating malodors in and around the sanitary unit.
- the proportions of synthetic detergent and acidic agent utilized in forming thesolid-sanitizing material are variable.
- the generally optimum objectives of the invention, however, are attained with ratios, basis weight, of the synthetic detergent to the acidic agent of the order of about I to about 100 of the synthetic detergent to about I of the acidic agent.
- the solid-cleaning sanitizing material used with the present invention may incorporate ingredients which serve to enhance, augment and complement the essential active ingredients thereof.
- germicidal and/or bacteriostatic agents such as benzyl dimethyl tetradecyl ammonium chloride and the tributyl tin chloride complex of an ethoxylated abietylamine condensate, chelating agents exemplified by ethylenediamine tetraacetic acid, perfumes and coloring agents may be added to the basic formulation.
- germicidal and/or bacteriostatic agents such as benzyl dimethyl tetradecyl ammonium chloride and the tributyl tin chloride complex of an ethoxylated abietylamine condensate, chelating agents exemplified by ethylenediamine tetraacetic acid, perfumes and coloring agents may be added to the basic formulation.
- such additives will usually comprise only a minor proportion, usually less than percent, by weight
- the synthetic detergents employed provide some scrubbing or abrasive action in the flush water
- this action can be substantially increased by replacing a portion of one or both of the essential ingredients of the solid-cleaning and sanitizing material with one or more solid inert substances exemplary of which are volcanic ash, diatomaceous earth, clays, asbestos, and the like.
- These substances serve also to bind the solid-sanitizing material into a solid, integrated body. In addition, they act as absorbing and/or adsorbing agents for foreign matter present in the sanitary unit.
- the quantity of inert substances used in the formulation of the solid sanitizing material is somewhat variable. Generally speaking, the quantity thereof used in lieu of one or both of the essential ingredients will be below about 50 percent, by weight, of the finished solid sanitizing body, more desirably from about percent to about percent, by weight, thereof.
- bars or molded bodies In forming bars or molded bodies from the synthetic detergents and acidic agents, they desirably are first placed in a suitable container and then heated until molten. The molten mass is stirred to form a substantially homogeneous mixture and then poured into molds of any desired shape or configuration. After cooling, the shaped bodies can be packaged for
- the following example is illustrative of various active ingredients which can be used as the cleaning and sanitizing material of the present invention but they are not to be construed in any way'as limitative of the full scope of the invention since various changes and modifications can be made in the light of the guiding principles and teachings disclosed herein.
