  • Publication number: 20100126608
    Abstract: An apparatus and method of use are disclosed for introducing botanical treatment liquid into water that is flowing from a hose bib into a hose. The apparatus includes a hose bib adaptor that can be connected to the hose bib with a flex hose and a treatment liquid input port that extends at an at least partly upward angle from the hose bib adaptor. In preferred embodiments, the hose bib adaptor includes a flexible segment to facilitate its adaptability to various configurations of hose bib.

  • Publication number: 20090121040
    Abstract: An apparatus and method are disclosed for introducing fertilizer, weed killer, pesticides, and other botanical treatment liquids into an irrigation system using an inexpensive, easily installed apparatus with exchangeable treatment containers. A water pipe adaptor connects in series with an irrigation pipe and supports a treatment container in an inverted, at least partly vertical orientation. Treatment liquid is drawn into the irrigation system by gravity and by Venturi effect suction. Embodiments include a replacement cap for sealing the adaptor, a barrier with a hole that controls the treatment dispensing rate, a constriction for increased suction, and/or a protrusion that breaks a membrane seal on a pre-filled container. In various embodiments, the container collapses or air and/or water displace the treatment liquid through venting holes. Embodiments with large containers include structural reinforcements or separate supporting stands.

  • Publication number: 20090119985
    Abstract: An apparatus and method are disclosed for applying fertilizer, weed killer, pesticides, and other botanical treatment liquids through an in-ground irrigation system using an inexpensive, easily installed apparatus with exchangeable treatment containers. An adaptor connects in series with an irrigation pipe and supports an inverted treatment container. Treatment liquid enters the irrigation system due to gravity, Venturi effect suction, a pressure differential caused by a constriction in the adaptor, and/or a diverter that diverts water into the container. Embodiments include a cap for sealing the adaptor, a barrier with a hole that controls treatment dispensing rate, a constriction for increased Venturi suction, and/or a protrusion that penetrates a membrane seal on a pre-filled container. Treatment liquid can be dispensed from a collapsible bag inside the treatment container. Embodiments with large containers include structural reinforcements or separate supporting stands.
