  • Patent number: 5908138
    Abstract: An improved dispensing lid for a container is disclosed. The dispensing lid having a generally planar top surface and a side wall depending therefrom and forming a cavity for operatively receiving a mouth of a container. The top surface having a recess and a reservoir of a predetermined depth extending downwardly from the recess and having an opening in the reservoir floor for access to the contents of the container.

  • Patent number: 5489415
    Abstract: The present invention relates to an improved urinal block composition comprised of fluid-soluble chemical components, and an improved dispenser to be used with that urinal block. Specifically, the present invention is directed to a unique combination of chemicals that when blended together to form a urinal block composition yields a stable product that is effective at deodorizing and cleaning urinals and toilets. The improvement of using an acid stable protease enzyme with the other fluid-soluble chemical components of the urinal block composition provides the advantage of dissolving and otherwise neutralizing odors associated with urinals and toilets. The urinal block is retained in and dispensable from a disposable dispenser assembly 10 for use in urinals and toilets.

  • Patent number: 5429764
    Abstract: The present invention relates to a composition and method for opening clogged drains. Specifically, the liquid drain opener composition of the present invention comprises about 70%-93% by weight sulfuric acid; about 1%-23% by weight water; about 0.01%-5% by weight of at least one corrosion inhibiting agent; and, about 0.01%-28.99% by weight of at least one surfactant. The drain opener composition may also contain mineral oil and inert filler materials, such as salt. The present invention is also directed to a method of opening clogged drains comprising the steps of contacting a clogged drain with the liquid drain opener composition of the present invention; the composition applying a protective coating to metal surfaces of the drain to substantially prevent corrosion of the metal; the composition applying a protective coating to concrete surfaces of the drain to substantially prevent erosion of the concrete; and, flushing the dissolved clog with water.

  • Patent number: 5324490
    Abstract: The present invention relates to a perfumed stable gel and to a deodorant container which retains a deodorant in the form of that perfumed stable gel, and which is adapted for use with various deodorant dispensers. The present invention also relates to a method of manufacture for the perfumed stable gel and the deodorant container in a unitary form. Specifically, the invention relates to a disposable deodorant container which retains a perfumed stable gel comprised of a unique combination of chemical components. The stable gel can be maintained at temperatures of up to 140.degree. F. and has a perfume content of up to 75%.

  • Patent number: 4096871
    Abstract: Discovery of a critical solution temperature vs acid strength profile leads to an aqueous acid-type drain opener composition consisting essentially of a solution of between about 80.8% and 84.5% by weight sulfuric acid. The composition may also contain about 0.1-0.5% by weight corrosion inhibitors, and about 15.0-19.1% by weight of inert materials, including 10-19% water. The resulting drain opener composition is not only effective to dissolve typical drain-clogging materials, but very much safer to use than the conventional highly concentrated (about 93% by weight) sulfuric acid drain openers in terms of providing time-based safety factor against severe acid burns.

  • Patent number: 4096593
    Abstract: Improved dispenser assembly for controlled release of bactericidal, detergent and aromatic agents upon flushing, which dispenser clips onto the upper edge of a toilet bowl. The assembly is specially adapted to bring a solid type deodorant/disinfectant cake into position along the side wall of the bowl but below the rim so that upon flushing, the flush water is directed to the cake in a turbulent action that releases limited amount of the cake. The dispenser disposes the cake above the bowl water line, and shields it from urine or splash so that it does not dissolve too rapidly.
