Definitions

  • the present invention is concerned with a dispenser of the kind for delivering aliquots of a liquid product from a reservoir by means of a pump which is manually operable.
  • a dispenser of the kind for delivering aliquots of a liquid product from a reservoir by means of a pump which is manually operable.
  • Such dispensers are often used in washrooms etc. for dispensing small amounts of a liquid soap product for hand washing purposes.
  • the US-patent 4,256,242 discloses a liquis soap dispenser comprising a housing, a collapsible bag for holding the liquid soap product and an operating lever or handle for actuating controlled amounts of soap from the bag.
  • the collapsible bag is connected to an outlet by means of a flexible conduit which comprises a pump.
  • These known types of dispensers offer hygiene and ease of handling for the user.
  • one problem with this kind of dispensers resides in the fact that only a small amount of liquid soap may be dispensed at the time due to the limited capacity of the peristaltic type of pump applied. The amount is usually not more than 0.5 to l ml.
  • Another problem which has been encountered with this type of pump is related to the way the pump operates: after the pump has been actuated the pump tubing recovers to its original shape and thereby sucks in liquid product for the next shot.
  • This sucking action of the tubing is directly related to the memory properties thereof which could decline depending on the material of the tubing and the operating time of the pump. As a consequence, the dosage of the pump per shot could decline.
  • the dispenser disclosed by this document comprises a disposable refill which comprises a reservoir and the bellow pump.
  • the disclosed dispenser is a rather specific one in that it can only be activated by electromagnetic means.
  • the present invention provides a dispenser for delivering aliquots of a liquid product comprising a housing (1) and a disposable refill package which is positioned inside the housing and comprises a collapsible reservoir (2) for the liquid product fitted with a bellow pump (3) , whereby the bellow pump comprises a product inlet valve and a product outlet valve and is manually operable via indirect ac- tuating means (10,11), and whereby the housing is provided with a narrow opening (9) into which a correspondingly shaped portion of the bellow pump located near the outlet valve thereof, can be securely fitted.
  • the present invention also provides a disposable refill package suitable for use in a dispenser according to the invention, comprising a collapsible reservoir (2) filled with a liquid product and attached thereto a bellow pump (3) provided with a narrow potion (9) which can be securely fitted into a correspondingly shaped opening located in the housing (1) of the dispenser.
  • the disposable refill package applied in the dispensing system of the present invention comprises a reservoir which is made of plastic material such as polyethylene, polypropylene and PVC.
  • plastic material such as polyethylene, polypropylene and PVC.
  • the refill is made of one piece.
  • the bellow pump comprises a liquid inlet valve and a liquid outlet valve which are respectively closed and opened by manually operable actuating means during each dose.
  • the liquid outlet valve is closed, the liquid inlet valve is opened by the suction action of the bellow when it recovers to its original position.
  • full liquid communication with the reservoir is achieved and the internal volume of the bellow pump is refilled by liquid sucked in from out of the reser ⁇ voir.
  • this action of the liquid inlet and outlet valves present in the bellow pump during and im ⁇ mediately after each dose no air can enter the internal volume of bellow pump and reservoir and the risk of con ⁇ tamination of the liquid to be dispensed is minimized.
  • the material of the bellow pump is preferably such that the suction action of the bellow pump is kept more or less constant, also after many dosages have been done.
  • the bellow pump is preferably equipped with an external spring. This spring ensures that constant dosage volumes are obtained during the operating life of the dispenser even with highly viscous liquids because it forces the bellow pump back into its original shape after each dose.
  • the housing is provided with a narrow opening into which a correspondingly shaped portion of the bellow pump located near the outlet valve thereof can be fitted. Furthermore, this narrow opening ensures that only refill packs con ⁇ taining the desired type of liquid product will be mounted in the dispenser, because other packs containing different products simply will not fit.
  • This narrow opening is desirably in the form of a slit having a width of less than 5 mm, preferably less than 2 mm.
  • the bellow pump is desirably provided with a discharge tube comprising a flow channel having a narrow internal opening with a diameter of less than 3 mm, preferably less than 2 mm.
  • a discharge tube comprising a flow channel having a narrow internal opening with a diameter of less than 3 mm, preferably less than 2 mm.
  • the dispenser of the present invention is equipped with manually operable in ⁇ direct actuating means. These may practically comprise a push rod which is coupled to the bellow pump via a tilting table.
  • the internal volume of the reservoir gradually decreases when liquid product is taken out and dispensed.
  • underpressure is created and, as a consequence, the bellow of the pump will be kept in a collapsed position.
  • the resulting reduction in length of the bellow pump can be used as an empty pack indicator.
  • Dispensers comprising a bellow pump with a dosing capacity of from about 0.1 to 10 ml are very suitable for use in washrooms. This type of dispensers having a dosing capacity in the mentioned range can be made much more compact than dispensers with peristaltic or plunger pumps with the same dosing capacity.
  • Figure 1 shows cross-sectional views of a dispenser accor ⁇ ding to the invention including a housing, a collapsible reservoir and a bellow pump, whereby the bellow pump is not activated (a) respectively activated (b) ;
  • Figure 2 shows a cross-sectional view of the bellow pump, including an inlet and outlet valve, and a discharge tube.
  • a housing (1) comprising a refill package which comprises a reservoir (2) and a bellow pump
  • the dispenser can be manually operated with indirect actuating means comprising a push rod (10) which is coupled to a tilting table (11) which in turn is connected to the bellow pump (3) .
  • a narrow portion (9) is connected to the bellow pump (3) which portion is used for securely positioning the refill package in the housing of the dispenser. Furthermore, the bellow pump is provided with a discharge tube (8) which comprises a flow channel having a narrow internal opening.
  • an external spring (12) is present between tilting table (11) and the housing. This spring ensures that constant volumes are dosed even when applying high viscosity liquids.
  • Figure 2 shows a bellow pump provided with an inlet valve (4) , an outlet valve (5) and a bellow section (6) . Because the internal volume of the bellow pump contains the liquid to be dispensed during the next dose, the bellow pump functions as a type of dosing section.
