Definitions

  • the present invention generally relates to container valves and, more particularly, the valve of the present invention may be used in so-called 'bag in a box' fluid dispensing applications where it is at of advantage to have a high flow valve or tap assembly.
  • Flow control valves and tap assemblies have been developed for use to dispense a wide variety of fluids from various types of containers.
  • One known application for disposable taps or valves is the so-called 'bag in a box' products in which a bladder is provided within a cardboard box or other semi-rigid container, and a low cost, disposable tap or valve is provided to dispense the fluid from the bladder.
  • Con ⁇ structions of this type have been used to dispense water and other beverages such as wine or juice, and other liquids such as various chemicals, lubricants, cooking liquids and the like.
  • the valve or tap component desirably is formed inexpensively, from low cost materials, since the entire package assembly including the valve is intended to be discarded once the content of the bladder has been fully dispensed.
  • the valve is intended only for a single use, although it may be operated many times during that use.
  • the valve must operate effectively to tightly close and prevent spills or leakage, even after long periods of use with frequent or infrequent opening and closing cycles
  • Known valves for this purpose have included an outer sleeve with a substantially circular outlet opening and an inner core having an inner volume in flow com ⁇ munication with the container and a transfer outlet that can be aligned with the sleeve outlet to enable flow therethrough:
  • Known transfer outlets in the core have been circular as well.
  • the hole in the core and the hole in the sleeve can be arranged one in front of the other or side-by-side and pulled or rotated to align all or a portion of the holes for controlled flow from the container to the outside.
  • the front of the outlet stream nearest to the person dispensing the fluid is often one of the more disrupted portions of the outlet stream, potentially splashing onto the person operating the valve.
  • splashing and spillage can occur.
  • the present invention provides a valve having an inner core with a transfer opening shaped to provide a straight, leading edge for exposing the outer sleeve outlet to flow from the container.
  • the present invention provides a flow control valve with an outer sleeve having an outlet and a core movable in the sleeve.
  • the core has an inner volume, an inlet opening and a transfer port.
  • the transfer port is positioned for pro ⁇ gressively exposing and covering the outlet to the inner volume upon movement of the core relative to the sleeve.
  • the transfer port includes a substantially straight segment defining the transition across the outlet during relative movement of the core in the sleeve.
  • the present invention provides a flow control valve with a sleeve defining an outlet and a core moveably disposed in the sleeve.
  • the core has a transfer port moveable over the outlet to open and close the outlet.
  • the transfer port has a substantially straight edge spanning said outlet during movement of said core.
  • the present invention provides a valve with an outer sleeve having an outlet opening and a hollow core rotatable and axially moveable in the sleeve.
  • the core defines an inner volume.
  • a transfer port through the core is configured for exposing the outlet opening to the inner volume.
  • the transfer port has a shape providing a straight transition between exposed and unexposed portions of the outlet, for any position of the core relative to the sleeve in which a portion of the outlet is covered by the core.
  • An advantage of the present invention is providing a fluid dispensing valve that creates a well-defined outlet stream of fluid from the container at all flow rates.
  • Another advantage of the present invention is providing a fluid dispensing valve that operates easily.
  • Still another advantage of the present invention is providing a fluid dispensing valve that can be manufactured inexpensively.
  • FIG. 1 is a perspective view of a valve in accordance with the present invention, with the valve shown connected to a fragment of a container;
  • FIG. 2 is a perspective view of the valve core for the valve in Fig. 1 ;
  • FIG. 3 is a cross-sectional view of the valve sleeve shown in Fig. 1;
  • FIG. 4 is an elevational view of the valve core shown in Fig. 2;
  • FIG. 5 is an enlarged fragmentary view of a portion of the valve sleeve shown in
  • FIG. 6 is an elevational view of the valve core shown in Fig. 4, but illustrating a different portion of the valve core;
  • Fig. 7 is a plan view of the bottom of the valve shown in Fig. 1 , illustrating the valve in a closed position;
  • Fig. 8 is a plan view similar to that of Fig. 7, but illustrating the valve in a partially opened position
  • Fig. 9 is a plan view similar to Figs. 7 and 8, but illustrating the valve in a half open position.
  • Fig. 10 is a plan view similar to Figs. 7, 8 and 9, but illustrating the valve in a fully opened position.
  • valve 10 in accordance with the present invention is shown installed for dispensing fluid from a container 12. It should be understood that valve 10 can be used for dispensing a variety of different types of fluids including beverages, cooking fluids, industrial fluids such as chemicals and lubricants, or the like from different styles and shapes of containers.
  • Valve 10 includes a valve body 14 and a valve core 16 operable in body 14 for exposing and covering openings therein to allow the flow of fluid from container 12 to the outside through valve 10.
  • Valve body 14 includes a substantially cylindrical sleeve 20 open at each of an inner end 22 and an outer end 24 thereof.
  • a flange 26 is provided at inner end 22 for attachment of valve 10 to container 12.
  • Flange 26 can be configured for heat sealing type attachment, crimp attachment or other suitable adherence or connection to container 12 and a bladder (not shown) disposed therein.
  • Sleeve 20 defines an outlet 28 and is provided with an extension 30 at outlet 28 for directing fluid flow from valve 10.
  • Outlet extension 30 also can be used for connecting valve 10 to other flow handling systems or devices, conduits, hoses or the like.
  • FIG. 30 While shown to be configured as a substantially smooth sided extension 30, it should be understood that other con ⁇ figurations including internally threaded or externally threaded bodies can be used.
  • An internal surface 32 of valve body 14 defines a primary seal bead 34 on the upstream side of outlet 28 and a secondary seal bead 36 on the downstream side of outlet 28.
  • Primary and secondary seal beads 34, 36 operate in sealing arrangement with core 16 to provide a fluid tight relationship between body 14 and core 16, so that fluid does not leak from valve 10.
  • a follower in the nature of a protuberance 38 is provided on internal surface 32 to cooperate with core 16, as will be described hereinafter, during opening and closing of valve 10.
  • Outer end 24 defines a notch for securing the valve in a closed position, as will be described also hereinafter.
  • Core 16 includes a substantially hollow cylindrical stem 50 and an actuator 52 having a knob 54.
  • Stem 50 has an open end 56 and defines an internal volume 58.
  • a transfer port 60 is defined by stem 50.
  • transfer port 60 is configured for selective positioning relative to outlet 28 for exposing all or a portion of outlet 28 to internal volume 58, thereby allowing fluid from container 12 to flow through open end 56 into internal volume 58 and out through transfer port 60 to outlet 28 and extension 30.
  • a wall 62 is provided on the outlet side of transfer port 60 to block fluid flow and to serve as a transition between stem 50 and actuator 52.
  • a helical slot 64 is provided and defines a path along which protuberance 38 traverses when valve 10 is actuated.
  • An end segment of helical slot 64 defines a locking pitch 66 at a different angle than the major extent of slot 64. Locking pitch 66 receives protuberance 38 when valve 10 is in a fully closed position and is at such an angle as to provide a pre-load against primary seal deed 34 to ensure a sealed and closed arrangement.
  • an end stop 68 is provided to inhibit unintentional over rotation of core 16 during opening.
  • slots 64 are provided on a diametrically opposite side of stem 50 for receiving a second protuberance 38 (not shown) in body 14.
  • a second protuberance 38 (not shown) in body 14.
  • Transfer port 60 is configured to expose outlet 28 to inner volume 58 and fluid flow therefrom and therefore provides a transition between portions of outlet 28 that are exposed and another portion of outlet 28 that is not exposed to inner volume 58.
  • Transfer port 60 has a somewhat teardrop-like overall appearance.
  • Transfer port 60 is partially defined by a substantially straight downstream segment 70 on the downstream side thereof and an adjacent substantially straight wall segment 72 forming a sub ⁇ stantially right angle with downstream segment 70.
  • Downstream segment 70 is the segment of transfer port 60 that is exposed in outlet 28.
  • Downstream segment 70 traverses along and over outlet 28 as valve 10 is either opened or closed. Segment 72 is provided along the side of transfer port 60 first approaching and exposing outlet 28 from the closed position during operation of valve 10 by rotation of core 16, as will be described more fully hereinafter.
  • lead segment 72 traverses along and adjacent the edge of outlet 28.
  • transfer port 60 is defined by a bulbous outwardly curved trailing segment 74 extending from straight downstream segment 70 to an upstream segment 76.
  • a connecting segment 78 of curved con ⁇ figuration joins upstream segment 76 to straight lead segment 72.
  • Actuator 52 is of sufficient length to extend just outwardly of sleeve 20 when valve
  • actuator 52 defines a tab 84 which settles into notch 40 when valve 10 is closed.
  • Tab 84 in notch 40 provides a 'catch' or slight interference to accidental opening of valve 10.
  • An upstream end of actuator 52 defines a beveled surface 86 to engage primary seal bead 34, preventing leakage when valve 10 is in the closed position.
  • Figs. 7-10 illustrate valve 10 in various operational positions. As shown in Fig. 7, valve 10 is closed. Accordingly, outlet 28 is not exposed to inner volume 58 which is positioned instead inwardly or upstream from outlet 28 relative to container 12, and rotated away from true alignment with outlet 28. Outer surface 82 covers outlet 28. [38] In the closed position, protuberances 38 are positioned in locking pitches 66 of helical slots 64. The angular relationship of pitches 66 provides a loading force of beveled surface 86 against primary seal 34. Diametrical interference can be provided between portions of primary seal bead 34 and outer surface 82 and between secondary seal bead 36 and outer surface 82.
  • primary and secondary sealing beads 34 and 36 can be ribbed and/or reinforced as necessary to provide an adequate seal to prevent leakage.
  • Primary seal 34 is adequate under most circumstances to prevent leakage; however, if any small amount of leakage does occur, secondary seal 36 inhibits the passing of fluid externally of valve 10 and further prevents leakage.
  • valve 10 To actuate valve 10 and begin flow from container 12, knob 54 is rotated in a coun ⁇ terclockwise direction. As core 16 is rotated in sleeve 20, protuberances 38 are first moved out of locking pitches 66 and then follow along helical slots 64 causing core 60 to move axially outward from body 14 while rotating therein. Exposure of outlet 28 to inner volume 58 occurs as downstream segment 70 passes over outlet 28, thereby aligning portions of outlet 28 with portions of transfer port 60. Continued rotation of core 16 increases the axially outward movement of core 16 relative to body 14 and exposes an ever increasing area of outlet 28 to inner volume 58 through port 60.
  • Fig. 8 illustrates valve 10 in an approximately one-quarter open position
  • FIG. 9 illustrates a half open position and Fig. 10 illustrates a fully opened position.
  • the moving front of a stream flowing from outlet 28 remains- defined at all times by straight wall segment 70, behind which the stream thickens. ' Because of the shape of port 60, all exposed portions of outlet 28 remain exposed as valve 10 is opened more fully.
  • Lead segment 72 follows along the edge of outlet 28 as core 16 simultaneously rotates in sleeve 20 and moves axially outward.
  • the fluid stream is defined by the curved wall of outlet 28 in the exposed portion thereof and flat wall downstream segment 70 of transfer port 60, which is moved in ⁇ creasingly outward relative to outlet 28.
  • the outlet stream remains tightly defined as the flow therefrom increases. The outlet stream is well-formed, without diverging streamlets or rippled, disrupted flow.
  • valve 10 As valve 10 reaches a fully open condition, with outlet 28 fully exposed to inner volume 58 through transfer port 60, protuberances 38 encounter end stops 68 in helical slots 64, thereby preventing over-rotation of core 16 and potential disengagement of core 16 from body 14.
  • Fig. 6 is an enlarged view of one protuberance or follower 38, illustrating an ad ⁇ vantageous feature thereof.
  • Protuberance 38 is a semicircular in shape and has a flat sided 90 on the inlet side of the valve. The increased surface area provided by flat side 90 readily accepts an increased load if container 12 is under pressure. There is less chance for core 16 creep toward an opened position as the core is forced outwardly and locking pitch 66 is urged against flat side 90.
  • helical slots 64 can be provided with notches or configurations into which protuberances 38 can settle to provide defined points for various valve openings and flow volumes.
  • valve 10 can be provided with semi-fixed opened positions into which core 16 can be adjusted to provide prolonged flow at fixed outlet stream sizes.
  • lead-in or assembly slots can be provided from the end of stem 50 to helical slots 64, thereby bypassing end stops 68 during assembly.
  • Such assembly slots (not shown) are substantially axially oriented from the outer end of stem 50 to an intersection with helical slots 64.
  • protuberances 38 are positioned at the entrance slot and core 16 is pushed axially into sleeve 20.
