Definitions

  • the invention relates to a pump for dispensing a fluid product, comprising: a liquid chamber, for containing a liquid product; a liquid inlet valve, for admitting a body of liquid product into the liquid chamber; a liquid outlet valve, for regulating passage of liquid product from the liquid chamber to a dispensing head; and compression means, for applying a compressional force to the body of liquid product, thus forcing liquid product from the liquid chamber through the liquid outlet valve, additionally comprising: an air chamber, for containing air; an air inlet valve, for admitting air into the air chamber; an air outlet device, for conducting air from the air chamber to the dispensing head; and pressurizing means for reducing the volume of the air chamber, thus forcing air from the air chamber through the air outlet device, wherein the liquid inlet valve is elastically biased in a closed position.
  • such a pump In use, such a pump is conventionally connected to a reservoir, for containing a supply of the liquid product, which is admitted to the pump through the liquid inlet valve.
  • the pump will be located above the reservoir, with the liquid outlet valve above the liquid inlet valve (hereinafter referred to as a "standing configuration”); in other applications, however, the pump will be located below the reservoir, with the liquid outlet valve below the liquid inlet valve (hereinafter referred to as a "hanging configuration”) .
  • Other configurations are, of course, also possible, e.g. with the pump located at a side of the reservoir.
  • fluid should be interpreted as encompassing a liquid, a suspension of a granulated solid in a liquid, a gel, a foam, and a spray, for example.
  • product should be interpreted as encompassing soap (including shower gel) , shampoo, disinfectant (including alcohols), detergent, moisturizer, hair conditioner, and exfoliating scrub, for example, including mixtures of these substances .
  • compression means should be interpreted as encompassing a piston, bellows, balloon, and/or membrane, for example. The same applies to the term “pressurizing means”.
  • the "liquid product” may be dispensed directly through the pump, or may first be mixed with another substance, such as air or another gas, another liquid, or a granulated solid, for example.
  • reservoir refers to any suitable type of container, whether rigid or flexible, such as a bottle, flask, or bag, for example.
  • a pump as described in the opening paragraph when combined with a liquid reservoir as referred to in the second paragraph, forms a fluid product dispenser.
  • WO 03/089152 describes dispensers which combine a liquid pump and an air pump mounted at, or adapted to be mounted at, the neck of a container which contains foamable liquid.
  • the liquid pump has a liquid pump chamber defined between a liquid cylinder and a liquid piston
  • the air pump has an air pump chamber defined between an air cylinder and an air piston.
  • Appropriate flow valves are provided to assure the operation of the respective pumps.
  • the liquid chamber usually has a liquid inlet valve. Either or both of an air outlet valve and a liquid outlet valve may be provided for the air discharge passage and the liquid discharge passage, respectively.
  • the inlet valve is resiliently urged to a closed position, so that in the rest condition of the pump it prevents liquid from flowing from the container into the liquid chamber.
  • dispensers are, for example, employed in washrooms, toilets, kitchens, hospitals, surgeries, hair/beauty salons, workshops and factories. In many cases, such dispensers are fitted in a holder that is mounted to a wall, often in the vicinity of a basin, bath, shower or toilet bowl; alternatively, such dispensers may be free-standing, and may be placed on a shelf, worktop or wash hand basin, or a trolley. In use, the pump is typically operated by hand, arm or elbow so as to dispense a quantity of fluid product.
  • this fluid product will be dispensed into the operator's hand, or onto a carrier such as a tissue or cloth, after which the fluid product is rubbed onto the skin or hair, or is applied from said carrier onto a surface to be sanitized, such as a toilet seat.
  • a carrier such as a tissue or cloth
  • a pump according to the invention has several advantages. For example, if the pump is employed in a hanging configuration, below a reservoir, and the liquid outlet valve should fail for some reason (e.g. break, jam or wear), only the liquid product contained in the liquid chamber can leak out of the pump - since the reservoir is sealed off from the liquid chamber by the fact that the liquid inlet valve is elastically biased closed. Because the liquid chamber generally has a drastically smaller volume than that of the reservoir (e.g. 0.4 ml vs.
  • Another advantage of the pump according to the invention is that, since the liquid inlet valve is elastically biased closed, contaminated product residue present in the dispensing head cannot make its way into a reservoir at the other side of the liquid inlet valve, and therefore cannot taint the contents of the reservoir.
  • a duckbill valve assumes the form of a tapering sleeve, with a relatively wide entry orifice and a relatively narrow exit constriction.
  • the sleeve is manufactured from resilient material, such as rubber, which, due to its intrinsic elasticity, causes the sleeve to close in upon itself at the narrow end, thus closing the constriction. Only when sufficient force Fi is applied, will the biasing elastic forces concerned be overcome, causing the sleeve walls to separate at the narrow end, thus opening the constriction and allowing flow through the sleeve. As soon as the opening force falls below Fi again, the sleeve will close once more. In this manner, the duckbill valve is thus pre-loaded shut.
  • the duckbill valve is positioned so that the sleeve tapers inward in the direction of intended flow.
  • the tip of the sleeve (the exit constriction) would point into the liquid chamber, whereas the base of the sleeve (the entry orifice) would face toward the liquid reservoir dock.
  • the valve can then be opened by creating an appropriate pressure differential across the valve, e.g. a negative pressure in the liquid chamber (or a positive pressure in the reservoir) ; the required negative pressure can be created during the pump's relaxation stroke (after its compression stroke) , whereby liquid product is sucked from the reservoir into the liquid chamber as the compression means relax (e.g. as a piston withdraws outward, or as a bellows or balloon expands) .
  • a further effect of the use of a liquid inlet valve that is elastically biased in a closed position is that the ratio of the quantity of displaced air to the quantity of displaced fluid is determined more precisely.
  • the volume of the body of liquid forced out with each stroke is more consistently the same .
  • the pump according to the invention can be any type of pump suitable under the circumstances.
  • the fluid product is foam.
  • An embodiment of such a pump additionally comprises: a mixing element, located in the dispensing head, for mixing liquid product and air emanating from the respective liquid and air chambers.
  • the mixing element may, for example, be a mixing chamber and/or a porous member, such as a gauze, sieve or mesh, for example.
  • the air outlet device may be a valve, a narrow duct, a swan neck, or a labyrinth passage, for example.
  • the term "air” should be broadly interpreted as encompassing other gases, such as N 2 , for example.
  • a foam pump of this type is described, for example, in US 5,271,530 (Daiwa Can Company) and US 2004/0149777 (Taplast) .

  • a detector for detecting that a member onto which fluid is to be dispensed has been offered to a dispensing head of the pump, and; an electric actuator, for actuating the pump on the basis of a signal output from the detector.

  • the employed detector may, for example, be based on heat detection, movement detection, the interruption of a light beam, a change in scattered light intensity (albedo change) , etc. indicating that a member such as a hand, cloth or tissue is being offered to the dispensing head, i.e. appropriately positioned to receive fluid product dispensed from that head.

  • pressurizing means 116 for reducing the volume of the air chamber 110, thus forcing air from the air chamber 110 through the air outlet device 114
  • a mixing element 118 located in the dispensing head 107, for mixing liquid product and air emanating from the respective liquid chamber 102 and air chamber 110.
  • FIG. 1 Also depicted is a collar 119, by means of which the pump 100 can be attached to a reservoir 20 (not depicted in Figure 1) .
  • Figure 5 shows a pump 100 coupled to a reservoir 20 in a hanging configuration, for example.
  • the following design choices have been made:
  • the compression means 108 are embodied as a piston, with a piston shaft 111 and an attached piston head 113, which can be moved telescopically in and out of a piston tube 103.
  • the piston shaft 111 is hollow, and has a central passage that forms part of the liquid chamber 102. Moving the dispensing head 107 toward the collar 119 causes the piston 108 to start a compression stroke, applying pressure to a body of liquid product present in the liquid chamber 102, and thus forcing liquid product from the liquid chamber 102 through the liquid outlet valve 106. On the other hand, moving the dispensing head 107 away from the collar 119 causes the piston 108 to start a relaxation stroke, causing negative pressure to build up in the (empty) liquid chamber 102.
  • the pressurizing means 116 are embodied as a bellows, within which is located the air chamber 110. Moving the dispensing head 107 toward the collar 119 compresses the bellows 116, reducing the volume of the air chamber 110 and thus forcing air from the air chamber 110 through the air outlet device 114. On the other hand, moving the dispensing head 107 away from the collar 119 causes the bellows 110 to relax, whereby air will be sucked into the bellows 110 through the air inlet valve 112. If the bellows 110 is made of resilient material, such as flexible plastic or rubber, it will be self-relaxing.
  • the air outlet device is embodied as a labyrinth of narrow passages.
  • the liquid inlet valve 104 is not elastically biased, and is here embodied as a ball bearing 104w that is free to move between two flanges 104x and 104y.
  • the flange 104x When used in hanging configuration (so that the pump 100 is upside down as compared to its depiction in Figure 1) , the flange 104x will form a valve seat against which the ball 104w can be pressed in a sealing manner; on the other hand, the flange 104y will act as a retainer, serving to prevent the ball 104w from falling (under the influence of gravity) into the liquid chamber 102, but being shaped such that liquid can nevertheless flow in the space between the ball 104w and the flange 104y, even when the ball 104w rests against the flange 104y. In use, such a liquid inlet valve 104 will normally be open, i.e.
  • the ball 104w will rest against the flange 104y (under the influence of gravity) . Only when sufficient pressure is built up in the liquid within the liquid chamber 102 (by movement of the piston 108 toward the liquid inlet valve 104) will the ball 104w be pushed away from flange 104y and toward valve seat 104x, thus closing the liquid inlet valve 104.
  • liquid inlet valve 104 in the previous paragraph is default open in hanging configuration, it will allow a continuous leak of liquid from the reservoir 20 through the dispensing head 107 in the event of a failure of the liquid outlet valve 106.
  • FIG. 2 shows a cross-section of a pump 100 for dispensing a fluid product, according to an embodiment of the current invention.
  • the pump 100 in Figure 2 is identical to that in Figure 1, except as regards the liquid inlet valve 104.

  • the liquid inlet valve is embodied as a duckbill valve.
  • the duckbill valve 104 has a wall 104c of resilient material, in the form of a tapered sleeve.
  • This sleeve 104c has a narrow end 104a (the exit constriction) and a wide end 104b (the entry orifice), and is positioned such that, when viewed from a liquid inlet orifice 121 in flow communication with a supply of liquid product in a reservoir 20, the narrow end 104a is distal and the wide end 104b is proximal, i.e.
  • valve sleeve tapers inward away from the reservoir 20 (and the liquid inlet orifice 121) and toward the liquid chamber 102.
  • the valve 104 will be elastically biased closed, as depicted in Figure 2.
  • the valve 104 will remain closed.
  • a negative pressure will arise in the liquid chamber 102, causing liquid product to be sucked through the valve 104 from the liquid inlet orifice 121; once the relaxation stroke has ended and the negative pressure in the liquid chamber 102 disappears again, the valve 104 will close once more.
  • the duckbill valve 104 is elastically biased closed, contaminated liquid product in the liquid chamber 102 and/or dispensing head 107 cannot migrate back into the reservoir 20. This means that a supply of sterilized liquid product in the reservoir 20 will not be contaminated by backflow through the valve 104.
  • valve 104 is elastically biased closed will limit leakage of liquid product in the event of a failure of the liquid outlet valve 106. If liquid outlet valve 106 were to break, jam or wear, for example, only the liquid product contained in liquid chamber 102 would leak out through the valve 106; the much greater supply of liquid product in the reservoir 20 would be held back by the inventive liquid inlet valve 104, which is elastically biased closed by default.

However, during the relaxation stroke of the piston 108, a negative pressure will arise in the liquid chamber 102. If the inward force exerted on the ball bearing 104g as a result of this negative pressure exceeds the elastic biasing force F 0 , then liquid product will be sucked through the valve 104 from the liquid inlet orifice 121; once the relaxation stroke has ended and the negative pressure in the liquid chamber 102 disappears again, the valve 104 will close once more.
