Definitions

  • the present invention relates to liquid dispensers; particularly to wall-mounted dispensers that use liquid container systems having a vessel containing the liquid, an upper fitment, a collapsible, resilient, pump tube and a pump tip with a nozzle through which the liquid is dispensed.
  • Liquids and semi-liquids such as food materials, medicines, and cleaning materials are commonly dispensed from countless numbers of existing such dispensers in use around the world. New dispensers are being added to existing markets and new markets constantly.
  • Wall-mounted liquid soap dispensers which dispense small portions of detergent upon application of pressure to a dispensing lever or member are commonly found in business, industry and institutional restrooms, and constitute a significant specialty industry.
  • the installed base of soap dispensers in the United States alone is estimated at several million.
  • Rigid containers such as form-fitting blow-molded polyethylene jugs are known to be used with pump tubes in some dispensers, particularly in Europe. A hole is made in the top of the jug, after it is iis installed in the dispenser, to enable air to replace the liquid as it is consumed.
  • the liquid container is supplied without a pump.
  • the existing pump is removed from the exhausted container and attached to the new container, and reinstalled with the new container.
  • bag-in-box containers hold the liquid soap or other desired material in a collapsible, flexible, transparent bag within a cardboard or paperboard box which is closed for shipping and storage.
  • a pump tube is attached by an upper fitment to the bottom of the bag.
  • the upper fitment may be a two-component rotatable fitment; a flanged upper component that is attached to the bag, and a tube coupling attached to the pump tube.
  • At the lower end of the pump tube is a pump tip with a nozzle from which the liquid is actually expelled.
  • the box is installed on a shelf in the dispenser, opened for use by tearing out a perforated section in the front and bottom of the box which leaves a slot through which the pump tube is extracted and positioned against a pressure support wall, held by respective upper and lower fitment recesses.
  • the pump tube is typically made of extruded or molded latex or similar material, and is typically about two and one half inches long, depending on the pump tips and dispensers it is intended to fit.
  • the system is sized so that one or two strokes of the pump lever should dispense a sufficient volume of soap for the average user's immediate use.
  • the check valve may be incorporated into the lower end of the pump tube, rather than actually in the pump tip. Also, some designs include a second check valve on the upper end of the pump tube to prevent back flow of fluid into the bag during the pressure stroke on the pump tube.
  • the volume requirement necessitates a larger diameter pump tube than the dispenser's lower recess provides for.
  • Some manufacturers use a molded-in, necked-down tube design to provide the desired working volume and still properly fit the tube recess. This necked-down feature creates a complex pump design that is inevitably more expensive to manufacture than using simple, extruded pump hose that could be cut to length.
  • the lower tube/tip locator recess of early dispensers was fundamentally a slot in a lower block sized to accept the lateral insertion of the outer diameter of the lower end of the pump tube.
  • Recent pump tip designs by this inventor illustrated by FIG. 6D, incorporate an upwardly-extending shank between the keyed elements and the tube coupling nipple, thus displacing the lower end of the tube up out of the recess.
  • This development permitted the use of a shorter pump tube, and offered the potential for a hard interface between the pump tip and the wall of the recess.
  • FIGS. 6A, 6B, 6C and 6E illustrate examples of the related art of pump tip designs and designate with dimension L the region that installs into the upper section of a typical lower fitment recess.
  • dispensers are in many ways constrained by the configurations of the existing installed base of dispensers. This creates a situation where even small improvements to dispenser and container components which remain compatible with existing designs, while bringing improvements or opportunities for improvements in the maintenance and performance of dispenser/container combinations, are important in the evolution of this art.
  • the invention is basically an improved liquid dispenser for dispensing liquid from a container that includes a pump assembly with an upper fitment connected to a pump tube and hence to a pump tip.
  • the dispenser has upper and lower fitment recesses, means for closing the lower recess, a vertical pressure support wall, and a pump lever that collectively constrain the pump tube to a precise operating envelope for improved pump performance and dispenser reliability.
  • the lower fitment recess provides means to grip or hold in the pump tip and prevent lateral and longitudinal movement of the pump tip.
  • the lower recess may have a hard interface with the extended shank of such pump tips, rather than a soft contact with the pump tube.
  • the dispenser has a hard, smooth, seamless exterior cover to resist build-up of scum and facilitate cleaning, closely- fitting mating edges between the cover and the back plate to resist infiltration of water.
  • the dispenser has a sloping upper exterior surface on the push bar to shed water, an ergonomic depression in the push bar to accept the heel of the user's hand for pumping action, and a bottom edge, the back side of which tapers to a small radius to minimize the accumulation of scum deposits resulting from contact with the user's wet palm and fingers.
  • the main purpose of the invention is to combine novel features and other improvements with the present design of liquid dispensers, in ways which will improve the maintenance and performance of the dispenser and introduce opportunities for further improvement in both dispensers and containers. Other and various objectives follow.
  • One object of the improved dispenser is to physically constrain the pump tube to a precise operating envelope in order to improve the immediate performance and reliability of the dispenser and to provide greater opportunity to make other adjustments and refinements to the components and operation of both the dispenser and the pump.
  • An additional object is to prevent the inadvertent displacement or dislodging of the pump tip from the lower fitment recess during operation of the dispenser.
  • Other objects are to eliminate the exposed vertical crack or seam of prior art dispensers, between the cover and the back plate, and to conceal and protect the interior of the dispenser from spray and falling water.
  • Still other objects of the invention are to have a lower fitment recess grip or hold the pump tip, with a vertical wall section conforming to the shape of the corresponding section of the pump tip and having keyed means to allow the use of pump tips intended to be compatible with the dispenser and to inhibit the use of potentially incompatible container systems; and further, to retain or prevent longitudinal movement or movement of the pump tip during operation while permitting the nozzle of the pump tip to protrude downward and function as intended.
  • Yet another object of the invention is that it work in combination with a pump tip design which includes an extended shank or upper section between any keyed elements and it' s upper end tube coupling whereby the attached pump tube does not extend down into the lower fitment recess, thus providing a hard interface between the shank and the recess.
  • Still yet other objects of the invention are to make the pressure point or contact surface profile of the pump lever more natural or comfortable to push, to reduce the degree to which liquids, scum and bacteria may accumulate on any exterior surfaces or on the back side lower edge of the pump lever where it may often touch the wet palm and fingers of the user, and to make these surfaces easier to clean and keep clean.
  • Yet still other objects are to provide the dispenser with the convenience and security of automatic latching capability upon closing the cover onto the back plate, and with a simple, unobvious means for unlatching the cover for servicing.
  • a further object of the invention is to provide a cover that sheds liquids, resists the buildup of scum and is easy to clean, and to provide simple means for assessing when it is necessary to replenish the liquid supply in the dispenser.
  • FIG. 1 is a perspective view of an improved dispenser.
  • FIG. 2 is a perspective view of an improved dispenser with the cover open, and loaded with a container of liquid soap.
  • FIG. 3 is a close-up partial perspective view of the pump retention components of the dispenser.
  • FIG. 3A is a partial front view of a lower fitment recess configured for and shown with an extended shank pump tip.
  • FIG. 3B is a partial front view of a lower fitment recess configured for and shown with a common pump tip.
  • FIG. 3C is a partial top view of a lower fitment recess.
  • FIG. 4 is a cross-sectional view of an improved dispenser, loaded with a container of liquid, closed, and ready to dispense.
  • FIG. 5 is a bottom view of an improved dispenser.
  • FIG. 5A is a close-up partial view of FIG. 5 bottom view.
  • FIG. 6A-6E are cross-sectional views of representative pump tubes and tips known and used in the industry.
  • an improved dispenser that uses a liquid container system having at least a container and pump, the pump comprised of an upper fitment, pump tube and pump tip, where the improved dispenser has a cover, a pump lever, and a back plate that is attachable to a flat vertical surface.
  • the back plate has a shelf for supporting the container, a closely-fitting upper fitment recess into which the upper fitment can be laterally inserted, a vertical pressure support wall against which the pump tube is positionable, and a closely- fitting lower fitment recess into which the pump tip can be laterally inserted.
  • the upper fitment recess is configured to prevent upward movement of the upper fitment and pump tube.
  • the lower fitment recess has a lower section structure to prevent downward movement of the pump tip when the dispenser is being operated.
  • the dispenser has a means for closing the lower fitment recess so that the pump tip is restrained from being laterally displaced out of the recess during operation.
  • the dispenser has a cover that can be attached in a closed position on the back plate, the cover and the back plate each having matching edge contours so that when the cover is in the closed position, the back plate and the interior of the dispenser are substantially concealed and protected from spraying and falling water.
  • the dispenser has a pump lever or actuator that bears on the pump tube at rest, effectively retaining the upper fitment within its respective recess, and which will collapse the pump tube against the vertical pressure support wall in a progressively downward manner when actuated by a user, causing a squirt or unit portion of liquid to be expelled into the user's palm.
  • the upper fitment recess, vertical pressure support wall, lower fitment recess, means for closing the lower fitment recess, and pump lever collectively constrain the pump, particularly the pump tube, to a precise, repeatable, operating envelope where the resulting performance characteristics become very stabilized. This results in improved performance and reliability, as well as creating the opportunity for further adjustments and improvements to the components and operation of both the dispenser and the container pump.
  • the lower fitment recess of the improved dispenser may have three sections.
  • An upper section has a vertically-extending wall and means therein to resist the forward movement of an installed pump tip, such as the opening being slightly smaller than it's interior width so that the corresponding section of a pump tip must be forced laterally into the recess.
  • the vertically-extending wall may have molded- in buttons, ribs, or other known means to hold or otherwise resist forward movement of the pump tip out of the recess.
  • a middle section may have keyed elements corresponding to mating keyed elements on compatible pump tips.
  • a lower section has a slot from front to center so that the nozzle of the pump tip may be laterally fitted into it in a downward-pointing attitude, the nozzle and the slot being smaller in diameter than the pump tip so that the lower section prevents any downward movement of the pump tip during operation of the dispenser, and retards lateral movement to help keep the nozzle pointing properly downwards.
  • the improved dispenser may be used with a type of pump tip having an extended upper section or shank terminated by a pump tube coupling where the wall of the attached pump tube does not extend into the recess when the pump tip is installed.
  • the recess/tip shank combination may be specifically designed to provide a hard interface between the shank and the recess.
  • the dispenser cover may be attached to the back plate and hinged so that it can be rotated between opened and closed positions. It may have an aperture that closes over the protruding nozzle of the pump tip when the cover is closed, the leading edge of which closes and secures the pump tip in the lower fitment recess.
  • the pump lever may have a concave exterior surface profile and the contact or push point approximately conforming to the heel of a user's palm, the exterior upper surface of the pump lever may be sloped so that liquids will run off those surfaces, and the cross-section of the bottom edge at the center of the lever may taper to a small radius so that it does not readily accumulate scum build-up caused by the user's wet palm and fingers being drawn back across the bottom of the lever.
  • the cover and back plate may be equipped with corresponding components of a self-latching mechanism that will secure the cover to the back plate when the cover is placed in the closed position, and the mechanism may be unlatched by depressing one or two inconspicuous buttons on the lower end of the dispenser.
  • the dispenser cover may have a relatively hard, smooth, substantially seamless exterior surface which sheds water, resists build-up of dirt and scum, and is easily cleaned. It may have a flush-mounted window through which the contents of the bag may be viewed when the cover is closed.
  • the improved dispenser may be used to dispense soap, body lotion, beverages, medicine, and other liquid and semi-liquid materials.
  • improved soap dispenser 10 consists of major components back plate 20, cover 30 and pressure member 40.
  • cover 30 is pivotally connected by a hinge mechanism to back plate 20 so that cover 30 swings forward and down to an open position which makes the interior portion of back plate visible and accessible for servicing; then upward and back over back plate 20 to a closed position which substantially conceals the front, sides and top of back plate 20 and the interior of the dispenser.
  • Back side of back plate 20 may be readily attached by any known means to a vertical surface or wall as in a bathroom or shower.
  • surface of cover 30 has a hard, smooth finish without vertical seams, joints or cracks, which sheds water readily and is easily cleaned with soap and water.
  • exterior surface of pressure member 40 has a similar hard, smooth finish, and is configured with a sloping upper surface 42 to likewise readily shed water.
  • pressure member 40 is pivotally connected to the interior of cover 30 to provide a fore and aft arc of movement. Face 41 of pressure member 40 is visible and accessible at lower end of cover 30 and has a slightly dished or concave surface that comfortably accepts the heel of user' s hand or palm for applying the pumping stroke.
  • a push on pump lever 40 of loaded dispenser 10 causes a small amount of soap to be dispensed from the bottom of dispenser 10 into the cupped palm and fingers of the user's hand, as further described herein.
  • the back side bottom edge 43 of pressure member 40 does not have any sort of shelf or ribbed surface, but tapers to a small radius. This minimizes the build-up of scum on the back edge of the pump lever resulting from repeated contact with the user's wet palm and fingers, and makes this area easier to clean.
  • mating edge 31 of cover 30 closes over a closely-fitting corresponding mating edge 21 on back plate 20, thereby resulting in a closed dispenser with no visible scum-prone seams between back plate 20 and cover 30, and provides excellent protection against infiltration of dust, soap, falling water and shower spray.
  • improved dispenser 10 is designed to be loaded with disposable container 60 of liquid hand soap.
  • Container 60 is of the conventional "bag-in-box" design and includes a flexible, substantially transparent, collapsible bag 61 containing liquid hand soap, to which is attached pump 62.
  • Pump 62 consists of upper fitment 63, to which is attached collapsible, resilient pump tube 64 made of extruded or molded latex, and pump tip 65 which is attached to the lower end of pump tube 64.
  • Bag 61 may or may not be contained in a box, from which combination the name derives.
  • Upper fitment 63 has a flange at it's upper end and a tube coupling at it's lower end.
  • Pump tip 65 has an upper section or shank 65a which terminates in a tube coupling, a middle section 65b which has keying elements to enable it's use in compatibly keyed dispensers, and a lower section 65c which is the nozzle from which the liquid is actually expelled when the pump is actuated.
  • tube 64 with attached tip 65 may be folded and stored within container 60 during shipping and storage.
  • container 60 is placed on shelf 50. Tear strip 60a is removed. Fitment 63, tube 64 and tip 65 are extracted and extended downwards, and properly positioned in the open dispenser as further described below. Cover 30 is then swing up and closed, and the improved dispenser is ready to use.
  • cover 30 includes window 32 for observing the level of the contents of bag 61.
  • upper fitment recess 53 is configured to accept the lateral insertion of upper fitment 63 in a closely- fitting relationship whereby the fitment is constrained from longitudinal movement when the dispenser is closed and operable.
  • upper fitment recess 53 is configured to restrain installed upper fitment 63 from any longitudinal movement.
  • lower fitment recess 55 has three sections.
  • Upper section 55a is comprised of vertically- extending side and back walls, the back wall being of a semi ⁇ circular cross section closely matching the cross section dimensions of the corresponding length L of compatible tube/tip combinations as typified by those pump tips of FIGS. 6A-6E.
  • Middle section 55b is comprised of keyed elements such as slots and stepped surfaces corresponding to the section 65b keyed mating elements such as the tabs of compatible tube/tip combinations.
  • Lower section 55c is a hemispherical retention structure or appendage which effectively closes the bottom of recess 55 except for slot 55d which is sized to accept lateral insertion of downward-pointing tip nozzle 65c while supporting and restraining pump tip 65 from any downward movement.
  • the lower edge of vertical pressure support wall 54 is located about one tube width higher than the top of recess 55, and slightly forward of the back wall of recess 55.
  • Pump tube 64 is thereby slightly deformed when tip 65 is fully inserted into recess 55.
  • Cam surface 44 of pump lever 40 bears on and partially deforms tube 64 against wall 54 when in at rest or in a relaxed position. Cam surface 44 then collapses tube 64 in a progressively downward manner against wall 54 when pump lever 40 is actuated.
  • upper section 55a is slightly narrower at it's opening, dimension A, than at its widest point, dimension B, thereby providing a snap-in fit installation with a hard interface for a pump tip with an extended shank 65a, such as illustrated by the tip of FIG. 6D, or alternately, a snug, push-in or compression fit for tips with the wall of pump tube 63 extending into length L portion of the tip, as illustrated by the tips of FIGS. 6A-C and E.
  • Back plate 20 and cover 30 are equipped with corresponding components of self-latching mechanism 22, which latches automatically when cover 30 is pushed into a closed position on back plate 20.
  • Latch mechanism 22 may be unlatched by pressing one or both of buttons 24 on the lower end or underside of dispenser 10.
  • cover 30 is configured with aperture 33, leading edge 33a of which closes slot 55d when cover 30 is closed, thereby restraining tip 65 from forward movement or displacement during operation of the dispenser.
