  • Publication number: 20090196897
    Abstract: The invention is a solid chemical concentrate system of at least two cooperative shapes. The first shape is an inwardly curved bar having an inner opening. The second shape is an insert which is capable of interlocking with the bar by insertion into the bar inner opening. The solid chemical concentrate provides chemical systems having active constituents which may be the same, different but compatible or functionally and chemically incompatible combined within one matrix to provide at least one substantially continuous surface. The system may also comprise an aqueous soluble or dispersible polymeric film cover.

  • Patent number: 5597019
    Abstract: An apparatus for diluting liquid concentrate materials to liquid use solutions. Liquid concentrates comprise common household cleaning and sanitizing materials such as window cleaners, hard surface cleaners, floor cleaners, sink cleaners, tile cleaners, drain cleaners and openers, glass cleaners, food preparation units, sanitizers, disinfectants, floor finishes and other similar institutional or industrial aqueous or aqueous-alcoholic cleaning solutions. The aspirator system is adapted to receive a container of liquid concentrate in a reservoir. The reservoir contains device to open the liquid concentrate. Additionally the reservoir contains device to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a receiver for the empty container. The receiver has filling device for the container that can deliver dilute use solution to the container.
