Definitions

  • the present invention relates to a rechargeable dispensing device for a liquid detergent product and more particularly to a dispensing device whereby controlled quantities of material can be accurately dispensed from a container containing the liquid detergent product.
  • the invention also relates to container filled with a liquid detergent product which is especially adapted to be used in the dispensing device of the invention.
  • the invention is particularly useful for accurately dosing concentrated liquid detergent products intended for cleaning, for instance in excess water.
  • EP-A-173 885 discloses a liquid soap dispenser comprising a chamber to which a refill container can be connected, and a piston pump provided with a stopping mechanism so as to adjust the piston stroke and thus the resulting soap volume to be dispensed.
  • this wall-mounted type of dispenser can only be used to dose small amounts of soap by manually operating the piston pump. The reason is that the dispenser does not contain a rack and pinion system coupled to the actuator for the piston pump.
  • US-4,662,195 and US-4,437,585 disclose similar types of wall-mounted dispensers.
  • US-A-3,758,005 discloses a rechargeable dispenser comprising a pistol-shaped grip and actuator as well as a housing containing a measuring chamber provided with an inlet and an outlet valve and coupled to a piston pump.
  • the stroke of said pump can be adjusted by turning a stop member so that the volume to be dosed can be varied.
  • this adjustment can only be carried out for a restricted number of dosing volumes to be dispensed.
  • this dispenser does not contain a rack and pinion system coupled to the actuator of the piston pump applied therein.
  • European patent application no. 92 201 795.9 relates to a dispensing device with which these objects can be achieved.
  • the dispensing device described by this not prior published document comprises a removable cartridge and a housing which is provided with a dosing chamber coupled to an adjustable pump, whereby the size and shape of the cartridge are such that a pouch containing the liquid detergent product can be fixed into it and that the cartridge with pouch can be tightly fixed into the housing so as to ensure an open but non-leaking connection between the detergent product in the pouch and the dosing chamber. It was found that the configuration of this dispenser device could be simplified by applying a rigid but collap- sible container instead of a cartridge in combination with a pouch and that the above-mentioned objects could also be achieved with said simplified dispenser device.
  • the invention provides a rechargeable dispenser device for a liquid detergent product, comprising a rigid but collap ⁇ sible container filled with said detergent product and further comprising a housing which is provided with a dosing chamber coupled to a pump which is manually movable by way of a rack and pinion system and the s ⁇ iroke of which can be adjusted, whereby the size and shape of the con- tainer are such that it can be tightly fixed in the housing so as to ensure an open but non-leaking connection between the detergent product in the container and the dosing chamber, by way of an output nozzle of the container.
  • the invention is also directed to the use of a container filled with a liquid detergent product in a dispenser device according to the present invention, said container having a size and shape such that it can be tightly fixed in the housing of said dispenser device so as to ensure an open but non-leaking connection between the detergent in the container and the dosing chamber, by way of an output nozzle of the container.
  • the dispenser device according to the invention is not only rechargeable, practical, manually operable with one hand, and accurately adjustable over a wide range of dosing volumes.
  • the device is also unique in that it is only suitable for use with certain special types of containers filled with the liquid product to be dispensed.
  • containers may be fixed into the housing of the dispenser by any means which ensures that an open and non- leaking connection between the detergent product in the container and the dosing chamber is established.
  • the container and housing contain elements so as to provide a quick and tight snapping fixation.
  • the above mentioned open non-leaking fixation could be best obtained by providing the housing with a hollow needle which is situated such that a membrane in an output nozzle of the container is pierced by the hollow needle when the container is fixed into the housing.
  • Containers which are suitable for use in the dispenser device of the invention, are rigid but collapsible. They preferably comprise one or more folds so as to make them collapsible. These folds are preferably located on at least two sides of the container and they are most preferably longitudinally directed.
  • the dispenser device could be made wall-mounted or por ⁇ table.
  • the device is preferably a portable device whereby the container is provided with a handle for carrying the device.
  • the pump is preferably a piston pump provided with a stop element which cooperates with a rod carrying the piston.
  • the stop element is infinitely adjus ⁇ table in the axis direction of the piston between predeter ⁇ mined limits so as to restrict the stroke of the piston.
  • the housing of the device preferably contains a display showing a value of the adjusted amount of deter ⁇ gent product to be dispensed from out of the dosing cham ⁇ ber.
  • a spring-loaded valve is preferably located inside the con ⁇ necting piece between the dosing chamber and the container. Said valve is installed such that it closes when the dispenser is operated and that it opens when the dosing chamber is filled with liquid detergent flowing out of the container .
  • the volume of the dosing chamber is preferably adjustable in between 5 and 100 ml, more preferably in between 5 and 50 ml.
  • the volume of the container filled with liquid detergent is preferably in the range of from 100 ml. to 10 litres, more preferably in the range of from 250 ml. to 5 litres.
  • the volume of the dosing chamber is preferably adjustable in gradations of 5 ml.
  • the dispensing device according to the invention contains a rack and pinion system which is connected to the piston pump on one side and to a manually operable handle on the other side, in order to be able to manually dose the above- mentioned preferred range of dosing volumes.
