Additionally, where multiple beads 26 are used, the beads 26 can be spaced apart from one another and spaced from the flange 22 and coupler end 28 ( FIG. 2 ) in any suitable arrangement.
  • the main body 12 defines a cavity 30 which is partially bounded by the coupler 24. Further, in some embodiments, the main body 12 comprises a seal 32 that extends into the cavity 30. In some embodiments, the main body 12 comprises a guide 34 through which a portion of the valve member 18 extends.
  • the valve member 18 comprises a base portion 36, a stem 38 extending from the base portion 36, an inner tubular portion 40, an inner facing wall 42, and intermediate tubular portion 44, an outer facing wall 46, and an outer tubular portion 48.
  • the length of the intermediate tubular portion 44 varies around the periphery of the valve member 18.

  • the valve member 18 further comprises a keeper 52 at the distal end portion of the stem 38.
  • the keeper 52 interfaces with a retainer 54 of the dome member 16.
  • the keeper 52 couples the valve member 18 to the dome member 16 such that the valve member 18 and dome member 16 move in tandem.
  • the dome member 16 is shown therein in greater detail.
  • the dome member 16 is shown in cross-section.
  • the dome member 16 has a base 56.
  • the base 56 is circular.
  • the base 56 can also be square, rectangular, hexagonal, octagonal, or in the shape of any other suitable polygon.
  • the cross-section of material is thicker at the base 56 of the dome member 16 than nearer the peak of the dome member 16.
  • At least some examples of the base 56 have a seat 58, which is configured to be received by the recess 60 ( FIGs. 5 and 7 ).
  • the dome member 16 comprises an elastomeric material.
  • the dome member 16 is elastically deformable from a first configuration 100 ( FIG. 2 ), wherein the fluid dispenser 10 is in a sealed configuration 50, to a second configuration 102 ( FIG. 13 ), in which fluid is permitted to flow out of the fluid dispenser 10.
  • the dome member 16 is predisposed to remain in the first configuration 100 unless a force is applied to it to depress the dome member 16.
  • the dome member 16 pulls the valve member 18 closed, via keeper 52, as long the dome member 16 is not depressed.
  • the guide 34 defines an opening 62 through which the stem 38 extends ( FIG. 2 ).
  • the opening 62 is triangular in cross-section.
  • the stem 38 has a triangular cross-section to correspond with the triangular cross-section of the guide 34.
  • the guide 34 can have any other suitable cross-sectional shape, for example circular, square, pentagonal, notched.
  • the main body 12 comprises one or more stand-off members 64. As illustrated in FIG. 5 , for example, a plurality of stand-off members 64 are employed. In some embodiments, the one or more stand-off members 64 are arranged to locate the dome member 16 within the recess 60. In some embodiments, the one or more stand-off members 64 ( FIG. 5 ) abut the seat 58 ( FIG. 4 ) of the dome member 16. Some examples of the main body 12 have at least three stand-off members 64. Some examples of the main body 12 have between three and fifteen stand-off members 64 and some embodiments have seven stand-off members 64, though any suitable number can be employed. Further, in at least some embodiments, the at least one stand-off member 64 is configured as a single stand-off member 64 having an annular shape; a semi-annular shape, for example with a segment cut out of it, can also be used.
  • the main body 12 has a dividing wall 66, separating the cavity 30 from the chamber 68.
  • the dividing wall 66 is oriented at a non-zero angle relative to a plane 120 ( FIG. 5 ) defined by the flange 22.
  • the main body 12 comprises an outer flow surface 106 and an inner flow surface 108, for example as shown in FIGs. 6 and 13 .
  • the dispensing port 20 forms an opening in the outer flow surface 106.
  • the main body 12 comprises one or more finger holds 70, for example two finger holds 70, which can be oriented in any suitable orientation.
  • the finger holds 70 are configured such that the user's index finger is placed between one of the finger holds 70, for example70a, and the flange 22 and the user's middle finger is placed between the other of the finger holds, for example 70b, and the flange 22. In this way, the user's thumb is used to depress the dome member 16 ( FIG. 13 ) to dispense fluid.
  • the main body 12 has one or more detents 72 ( FIGs. 1 , 5 , 7 ).
  • the detents 72 retain the cap 14 ( FIG. 12 ) until the cap 14 is removed, as discussed below.
  • Some embodiments of the main body 12 have two opposing detents 72, which can take on any suitable configuration.
  • the detents 72 are openings extending through a portion of the respective finger hold 70a, 70b.
  • FIG. 10 is a cross-sectional view of the valve member 18.
  • the stem 38 has a generally triangular cross-section, corresponding to the cross-section of the opening 62 of the main body 12 ( FIG. 7 ).
  • the keeper 52 is located at a distal end of the stem 38. Just proximal of the keeper 52 is a narrowed portion 74 of the stem 38. The narrowed portion 74 fits into the catch 76 of the dome member 16 ( FIG. 4 ), thereby coupling the dome member 16 and the valve member 18 so that they move in tandem.
  • the valve member 18 has a sealing surface 78 ( FIG. 10 ) which contacts the seal 32 ( FIG. 2 ) when the fluid dispenser 10 is in the sealed configuration 50. Due to the relatively large area of contact between the sealing surface 78 and the seal 32, the oxygen transmission rate into the fluid can be minimized. This is particularly important in certain industries, for example the wine industry.
  • the valve member 18 has a face 80.
  • the face 80 is angled relative to the longitudinal axis 81 of the stem 38. Further, the face 80 is configured to abut, or nearly abut, the dividing wall 66 ( FIG. 2 ) of the main body 12.
  • the face 80 is angled relative to the longitudinal axis 81 of the stem 38 by an angle ⁇ , which is less than 90 degrees and, in some examples, is between 45 and 70 degrees. Angle ⁇ is measured between the longitudinal axis 81 and the face 80 from a location on the face 80 where the intermediate tubular portion 44 is at its longest (as measured parallel to the longitudinal axis 81 of the stem 38).
  • the face 80 is angled relative to the valve seal plane 122 ( FIG. 10 ) by a non-zero angle ⁇ .
  • the valve seal plane 122 is defined by a plane extending through the center of the sealing surface 78 along the periphery of the valve member 18. As illustrated in FIG. 10 , the valve seal plane 122 extends into and out of the page. In some embodiments, the angle ⁇ is between 20 and 45 degrees. In at least some embodiments, the longitudinal axis 81 is orthogonal to the valve seal plane 122.
  • FIGs. 11 and 12 show an example of the cap 14.
  • Some embodiments of the fluid dispenser 10 have the cap 14 affixed thereto until the fluid dispenser 10 is used to dispense fluid, at which time the cap 14, or at least a portion thereof, is removed to provide access to the dome member 16.
  • the cap 14 is configured to show evidence of tampering and, in at least some examples, once it is removed from the main body 12, it cannot be easily reattached.
  • the cap 14 has a tab 82, a body portion 84, and a bond strip 86. Extending from the body portion 84, the cap 14 comprises at least one ear 88. As illustrated in FIG. 12 , for example, the cap 14 has two ears 88. The ears 88 snap-fit into the detents 72 ( FIGs. 5 and 7 ) of the main body 12. Further, in some embodiments, the bond strip 86 is attached to a lip 92 ( FIG. 5 ) of the main body 12. The bond strip 86 can be attached to the lip 92 in any desirable way, for example with adhesive or via ultrasonic welding. In some embodiments, the bond strip 86 has a plurality of teeth 94 ( FIG. 12 ) which provide contact points to contact the lip 92. The teeth 94 are flattened during ultrasonic welding, for example, to yield a high strength bond between the bond strip 86 and the lip 92.
  • the cap 14 has at least one tear strip 90. As shown in FIG. 1 , for example, the cap 14 has two tear strips 90. In some examples, the tear strip(s) 90 extend entirely through the material of the body portion 84 along portion of length of the tear strip(s) 90. A shown in FIG. 11 , for example, the tear strips 90 extend through the material near where the tab 82 adjoins the body portion 84. With regard to FIG. 12 , as the tear strips 90 extend inwardly into the body portion 84 from the periphery of the cap 14, the tear strips 90 are thicker than nearer the periphery. Stated differently, the material thickness of the tear strips 90 increases along the length of the tear strip 90.
  • the material thickness of the tear strips 90 is thinnest nearer the outer periphery of the cap 14. The thickness increases from the periphery until the tear strips 90 end at 96, where the material thickness of the tear strip(s) 90 is the same as the material thickness of the adjacent portion of the cap 14. Therefore, along a portion of the length of the tear strips 90, the tear strips 90 are reductions in the material thickness of the body portion 84.
  • Removal of the cap 14, for example by a user wishing to dispense fluid from the fluid dispenser 10, is carried out by pulling on the tab 82.
  • the tab 82 As the tab 82 is pulled, the tear strips 90 begin to tear along their length and cracks propagate until the tear strips 90 end at 96. At this point, the ears 88 snap out of the detents 72 and the dome member 16 is partially exposed to the user.
  • the user continues to pull on the tab 82, at which point the cap 14 fractures at the attachment columns 98 ( FIG. 12 ). In this way, the bond strip 86 remains attached to the main body 12, and the body portion 84 and tab 82 of the cap 14 are removed from the bond strip 86 and are discarded.
  • the user can dispense fluid by depressing the dome member 16, as shown in FIG. 13 , wherein the fluid dispenser 10 is in a flow configuration 104.
  • the dome member 16 elastically deforms to take on the second configuration 102 when it is depressed.
  • the dome member 16 consequently moves the valve member 18 inwardly and sealing contact between the seal 32 and the sealing surface 78 of the valve member 18 is broken.
  • fluid is permitted to flow between the valve member 18 and the dividing wall 66 and out through the dispensing port 20.
  • the fluid is further permitted to flow interiorly within the outer flow surface 106 and exteriorly to the inner flow surface 108 before exiting the fluid dispenser 10 via the dispensing port 20.
  • a flow passage 124 ( FIG.
  • the flow passage 124 is a slanted passage, relative to the longitudinal axis 81 ( FIG. 10 ), and at least a portion of the flow passage 124 extends 360 degrees around the stem 38.
  • fluid is also permitted to flow past the guide 34, between the stem 38 and the guide 34, and into the chamber 68. Nonetheless, because the dome member 16 is sealed against the main body along recess 60, fluid is not permitted to exit the fluid dispenser 10 by any way other than through the dispensing port 20.
  • the fluid dispenser 10 In order for the fluid to flow out of the fluid dispenser 10, it has to flow around the valve member 18. Due to the shape of the valve member 18, along with the guide 34 extending into the cavity 30, fluid must navigate a circuitous path. And, upon release of the dome member 16, the dome member 16 returns to its first configuration 100 ( FIG. 2 ), the sealing surface 78 again comes into contact with the seal 32, and flow of fluid out of the dispensing port 20 ceases. Further, upon release of the dome member 16 and closure of the valve member 18, the fluid dispenser 10 can eliminate dripping.
  • flow of fluid out of the dispensing port 20 is reduced, however, upon release of the dome member 16 but prior to the sealing surface 78 sealing against seal 32. This is due in-part to the guide 34 extending a relatively long distance into the cavity 30. Further, because the inner tubular portion 40 overlaps a greater portion of the guide 34 at the bottom of the valve member 18 than at the top of the valve member 18, the flow of fluid around the valve member 18 is slowed prior to contact between the sealing surface 78 and the seal 32. And, in some embodiments, the face 80 is disposed at a non-zero angle, ⁇ , relative to a sealing plane 110 ( FIGs. 6 , 14 ) such that fluid flow is reduced prior to contact between the sealing surface 78 and the seal 32.
  • the sealing plane 110 is defined by a plane extending through the center of the contact surface 126 of the seal 32 such that at each location around the periphery of the seal 32, the center of the contact surface 126 lies on the sealing plane 110.
  • the contact surface 126 is the surface of the seal 32 that mates with the sealing surface 78 when the fluid dispenser 10 is in the sealed configuration 50 ( FIG. 14 ).
  • the non-zero angle ⁇ is between 20 and 45 degrees.
  • the fluid dispenser 10 when the fluid dispenser 10 is in the sealed configuration 50, there is no head pressure from the fluid within the container pushing outwardly on the dome member 16 because the sealing surface 78 and seal 32 are disposed between the dome member 16 and the fluid in the container. Additionally, head pressure from the fluid tends to aid in closing the fluid dispenser 10 by pushing the valve member 18 into the seal 32 of the main body 12.
  • FIG. 14 a detailed cross-sectional view of a portion of the valve member 18 is shown with a portion of the main body 12. As shown, the fluid dispenser 10 is in the sealed configuration 50.
  • the outer tubular portion 48 has a lobe 112 ( FIGs. 10 and 14 ) that contacts the seal 32.
  • the lobe 112 moves toward the seal 32, ultimately sliding along incline 114 of the seal 32. Subsequently, the lobe 112 moves past the incline 114 until the valve member 18 comes to rest against the main body 12 such that the sealing surface 78 contacts the contact surface 126.
  • the outer tubular portion 48 pushes the seal 32 inwardly toward the intermediate tubular portion 44.
  • the intermediate tubular portion 44 comprises a wedge 116.
  • the wedge 116 comes into contact with the distal most end of the seal 32.
  • the wedge 116 contacts on opposite side of the seal 32 than the lobe 112. This arrangement prevents creep and deformation of the seal 32 over time in order to ensure proper sealing of the fluid dispenser 10, even after a period of shelf time or use.
  • the seal 32 is prevented from undergoing too much deformation because it is situated between the wedge 116 and lobe 112.
  • the lobe 112 and shape of the seal 32 and valve member 18 provide a relatively large area of contact between the seal 32 and valve member 18, thereby reducing the oxygen transmission rate of the fluid dispenser 10.
  • a capillary gap 118 is disposed between the valve member 18 and the guide 34. The presence of the capillary gap 118 eliminates post-closure dripping.
  • the main body 12 is made of HDPE (high density polyethylene), although other materials are also suitable.
  • the valve member 18 is made of HDPE, though other materials are also suitable.
  • the cap 14 is made of HDPE, though other materials are also suitable.

  • the dome member 16 is made of a TPE (thermoplastic elastomer), although other materials can also be used.
  • TPE thermoplastic elastomer
  • the various components can be injection molded and assembled.
  • At least some examples of the fluid dispenser 10 are assembled by inserting the valve member 18 into the main body 12 such that stem 38 extends through the guide 34 ( FIG. 2 ).

  • the dome member 16 is added to the main body 12 by inserting the keeper 52 ( FIG. 10 ) into the retainer 54 ( FIG. 4 ).
  • the dome member 16 is seated against the recess 60 ( FIG. 7 ).
  • the cap 14 is added by placing the ears 88 ( FIG. 11 ) within the detents 72 ( FIG. 5 ); the bond strip 86 ( FIG. 12 ) is pressed against the lip 92 ( FIG. 5 ) and the two are ultrasonically welded together.
  • the dome member 16 even when the dome member 16 is in the first configuration 100 ( FIG. 2 ), it continues to exert an outward (closing) force against the valve member 18. This helps to ensure sealing between the valve member 18 and the main body 12 as well as between the dome member 16 and the main body 12.
  • the coupler 24 can have any desired length or configuration.
  • the coupler 24 can be configured to attach to a bag-in-box container, bag container, box container, or any other container with standardized or non-standardized shape.
