  • Patent number: 8221696
    Abstract: A detergent dispensing device for an automatic washing machine has a cartridge, a selecting mechanism, an operating mechanism, and a thermal element. The cartridge includes a plurality of chambers to accommodate a detergent composition. The selecting mechanism selectively exposes each chamber to wash liquor allowing the detergent, in use, to be washed out of the chamber. The operating mechanism is movable from a first position to a second position for loading mechanical energy into the device which provides a restoring force for the operating mechanism. The thermal element retains the operating means in the second position and is arranged to move when subjected to an elevated temperature prevailing in an interior of the washing machine during a wash cycle, thereby the thermal element moves or releases the operating mechanism. The operating mechanism is arranged to advance the selecting mechanism to an adjacent chamber as the cartridge remains stationary.

  • Patent number: 5788123
    Abstract: A dispenser for paste compositions is formed of a housing having an inside wall formed about a longitudinal axis for containing said compositions and being open at one end. A piston is arranged to move axially within the housing to urge the compositions towards the open end. A locking mechanism supports the piston within the housing against the inside wall and prevents the piston from moving in a direction opposite to a dispensing direction. A head part is arranged at the open end of the housing for displacement of a portion of the composition to be dispensed. A push button is arranged laterally next to the head part for pressing against and deflecting at least a part of the head part The head part has a centrally arranged closing valve formed with a valve body, the valve being opened and closed upon the activation of the push button. A connecting rod passes axially through the housing and is held by a holder positioned in a guide cylinder of the valve body with very little axial free play.
