  • the dosing disk is connected to the cap via a central shaft and has two holes on either side of the shaft such that the arc described by one hole does not at any point coincide with the arc described by the other hole.
  • the dimensions of each hole are such that the amount of medicament taken up and dispensed during the operation of the dispensing mechanism corresponds to a unit dose of that medicament.
  • Operation of the dispensing mechanism involves rotation of the cap which causes rotation of the dosing disk. During the operation holes in the upper and lower plates and the dosing disk are aligned with respect to each other thereby 2 dispensing unit doses of the medicament.
  • Patent US4346823-A discloses a container closure for divided material such as powders which has a measured dispensing portion whereby a fixed volume of material may be dispensed.
  • the device may be positioned so that non-measured quantities may also be dispensed.
  • the device consists of a first cap with an end wall, a measuring unit attached to one side of the end wall and a second cap attached to the other side of the end wall.
  • the first cap may be attached to a container so that the end wall closes the opening in the container.
  • the second cap is rotatably mounted on the first cap and can be selectively placed in a closed position, a measured dispensing position and a non-measured dispensing position.
  • Patent GB1582628-A discloses a container with rotatable cap for dispensing granular material.
  • the cap is snap fitted and has an offset aperture which aligns with a scalloped mouth of a container body.
