Definitions

  • the present invention relates generally to dispensing units and, in particular, to foam soap dispensing units.
  • Foam soap dispensing systems are common and popular, as foam soaps provide effective cleansing using less soap than liquid or solid soaps. Many foam soaps can be absorbed into the skin and do not require washing or rinsing, and thus save water.
  • Disinfectant foam soaps are popular, as cleansing can be provided through the foam without use of water in areas such as hospitals, public bathrooms or laboratories.
  • Foam soap dispensers generally require a user to press downwardly on a dispenser to operate a pump to draw liquid soap upwardly, and expel the liquid soap from the pump as foam.
  • a dispenser to operate a pump to draw liquid soap upwardly, and expel the liquid soap from the pump as foam.
  • Such are typically bench mounted or freestanding. Freestanding units may be prone to damage, as such unit can be removed from a surface on which they are placed. For reasons of hygiene, these foam dispensers are likely unpopular in areas such as hospitals, laboratories and public bathrooms. Such foam dispensing systems are also often costly to maintain and prone to leakage.
  • a dispensing unit comprising: a reservoir configured to contain a volume of liquid detergent exposed to atmosphere;
  • a pump positioned beneath a base of the reservoir, configured to dispense foam; a conduit ha ing a proximal end coupled to an input of the pump, the conduit extending upwardly from the base and curved such that a distal end of the conduit is positioned substantially adjacent to the base; and
  • an operational mechanism comprising an actuator and a motorised unit, wherein the actuator is configured to activate the motorised unit to operate the pump to transport a. portion of the liquid from the reservoir through the conduit to an outlet of the pump by which the portion is dispensed as foam.

  • the container 1 10 is a substantially box-like container.
  • the container 110 is preferably manufactured of a durable plastics substance, which is preferably substantially transparent, such that a user can see contents thereof, and user or maintainer can ascertain if the container 110 requires refilling.

  • the opening 214 is closed by the pump assembly 130 and the conduit 120, thereby preventing liquid from flowing out of the opening 214.
  • the slot 210 provides contact to external atmosphere to any reservoir of liquid contained inside the container 1 10. The liquid contained within the container 110 therefore absorbs an amount of atmospheric air by simple exposure. If a cap is used to close the slot 210, the cap should preferably not hermetically seal the slot 210.
  • the slot 210 also allows atmosphere to enter the container 110 to balance pressure within the container 100 following operation of the pump 130. Deformation of the container 1 10 due to atmospheric pressure following repetitive pump use is thus prevented.

  • Pumps such as those disclosed in WO/2009/038454 are normally operated in an upright position, above a reservoir of liquid soap, where a user presses down on an actuator of the pump so that liquid is drawn upwardly into the pump.
  • Such pumps normally contain an air inlet, such as a hole 308 in a surface of the body 302, as shown in Fig. 3A. The air inlet permits air to mix with the liquid detergent to cause foam to be discharged from the pump.
  • the hole 308 is sealed by the manufacturer of the unit 100.

  • Seal the hole 308 allows for decreased leakage of liquid from the unit 100 through the pump 300.
  • An input valve (not shown) is provided in an upper surface 312 of the pump 300, through which liquid detergent can be provided to the pump 300.
  • the pump 300 operates when the nozzle 304 is pushed or pressed towards and into the body 302. Operation of the pump creates a vacuum in an area surrounding the pump input, such that balancing of pressures thereafter sucks a volume of the liquid into the pump 300, similarly to operation described in WO/2009/038454.
  • the volume of liquid is dispensed as foam from the nozzle 304 through the mesh 306.

  • the gears 532 are connected to a disc 534, which is coupled to the lever 510 by a U- shaped connecting lever 536.
  • Action of the internal motor 530 causes rotation of the gears 532 and disc 534, and thus lowers or raises the connecting lever 536 and, in turn, the lever 510.
  • a mechanism other than gears may be used, such as a pulley mechanism. Connection of the lever 510 to the connecting lever 536, the disc 534 and the gears 532 allows the lever -510 to be positioned at a suitable distance from the motor 300 to protrude through the slot 522.
  • the motor 530 is connected to battery B, stored in the battery section 506, as illustrated in Fig. 5E.

  • the switch matrix 540 connects the battery B to the motor 530 with a given polarity to energise the motor 530 to rotate. Operation of the motor 530 causes the gears 532 to operate such that an outer gear 535, and thus the disc 534, moves though one full rotation of 360°. The lever 510 is thus raised from, and returned to, the resting position. The raised position is determined by positioning of the disc 534 on the gear 535. Upon completion of one full rotation of the disc 534 on the gear 535, the lever 510 is restored to the resting position.

  • the motor 530 raises the lever 512 and pushes the output 316 of the pump assembly 130 upwards.
  • the slot 522 has a height such that the lever 510 is raised to a sufficient degree to operate the pump 300 by depressing the nozzle 304 into the body 302 of the pump 300. Operation of the motor 530 subsequently lowers the lever 512 to allow the nozzle 304 to release.
  • the pump 300 may also be pushed upwardly to compress the spring 310, and the nozzle 316 depressed sufficiently to operate the pump 300. Decompression of the spring 310 allows the pump and lever to return to resting position with greater speed
  • Operation of the pump creates a vacuum in a valve of the pump, which causes a portion of liquid soap in the container 110 to be sucked from the distal end 418, through the proximal end 420 and the pipe 408 to the input of the pump 300.

  • Atmospheric air may be dissolved into the liquid detergent upon mixing to the desired ratio with water, and/or on pouring liquid detergent into the container 110.
  • the container 110 and the hose 402 also contain atmospheric air when empty prior to initial use. Dissolved air in a reservoir of liquid detergent is sufficient to create foam.
