Definitions

  • This invention relates generally to dispensing devices and packages. More specifically, the present invention relates to metering devices that can controllably dispense fluid media from a source of fluid media while simultaneously providing a construction for assisting in the delivery and application of the fluid media to a surface for treating that surface. This invention further relates facilitating the preparation and use of dispensing devices and packages.
  • fluid material and media are employed for different purposes through commerce and industry.

  • this material When this material is sold in commerce, it must be contained and stored in some type of container. When that product is used, it must be dispensed from its storage container to a location for use.
  • a flexible container body with a nozzle tip is commonly provided for such a purpose.
  • An application of such use is for the dispensing of ketchup where the container body is squeezed by the user to urge the fluid material out from the nozzle tip and accurately to a desired location.
  • the amount of fluid delivered is determined by the how much the user squeezed the container body.
  • this yields erratic results where more or less fluid material is delivered on each successive squeeze of the container body.
  • the container must be held upright to avoid leakage because no valves are employed. Therefore, there is a need for a dispensing package that can deliver the media contained therein a controlled and metered fashion.
  • a flexible container holds a volume of fluid material to be delivered.
  • a single one-way check valve is provided as an exit port from the flexible container. When the flexible body is squeezed, the material is urged out under pressure through the valve.
  • a dual valve construction is employed to provide for controlled metered dispensing of media from a package.
  • these known devices require that the entire package be disposed of when the supply of media to be dispensed has been depleted.
  • the present invention preserves the advantages of prior art liquid dispenser and docking stations and supports therefor. In addition, it provides new advantages not found in currently available devices and overcomes many disadvantages of such currently available devices.
  • the invention is generally directed to a novel and unique dispenser for dispensing fluid materials. Many types of fluids may be dispensed using the present invention and liquid laundry detergent is merely one example and will be discussed in detail herein. This invention shall not be considered to be limited to the dispensing of laundry detergent in a washing machine environment.

It is envisioned that each press of the button on the nozzle at the free end of the hose dispenses a specific predetermined amount of fluid from the nozzle. Thus, a metered dose of laundry detergent can be delivered through the nozzle of the hose that could completely obviate the need for measuring and use of a measuring cup. For example, the dosing can be set to a known amount and the user can simply press the button multiple times to achieve the desired total amount.
