PRIORITY CLAIM 
     This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 62/818,899, filed Mar. 15, 2019, and U.S. Provisional Application Ser. No. 62/812,512, filed Mar. 1, 2019, both of which are expressly incorporated by reference herein. 
    
    
     BACKGROUND 
     The present disclosure relates to dosing dispensers for mounting on the top of bottles, or other containers, and in particular, to a dosing dispenser including a body portion coupled to a container and a flip-top cap coupled to the body portion. More particularly, the present disclosure relates to a dosing dispenser with a syringe receiver. 
     SUMMARY 
     According to the present disclosure, a closure includes a lid and a flip-top cap mounted to the lid. The lid includes a top wall formed to include an opening and a side wall that extends downwardly from the top wall and extends circumferentially about a central axis. The flip-top cap is mounted to the lid for pivotable movement about a cap pivot axis relative to the lid between a closed position and an opened position. 
     In illustrative embodiments, the closure further includes a child-resistant closure-release mechanism including a lock tab coupled to the flip-top cap to move therewith and first and second retainer rails coupled to the outer side wall of the lid in a fixed position relative to the flip-top cap. The lock tab is deformable relative to the lid from a locked position to an unlocked position. In the locked position, the lock tab engages the first and second retainer rails to block the flip-top cap from pivoting about the cap pivot axis to the opened position. In the unlocked position, at least a portion of the lock tab is deformed inwardly toward the inner side wall of the lid to disengage the lock tab from the first and second retainer rails. 
     In illustrative embodiments, the closure further includes a valve including a central port, an upper disk, and a lower disk. The central port is sized and arranged to extend through the central aperture formed in the top wall. The upper disk is coupled to the central port and arranged against an inner surface of the top wall. The lower disk is coupled to a lower surface of the upper disk. The central port and the upper disk are formed to include a first passageway that extends along the central axis. The lower disk is formed to include a second passageway that extends along a second axis that is transverse to the central axis. 
     In illustrative embodiments, the closure further includes an anti-suction feature coupled to the top wall of the lid and configured to maintain spacing between an upper surface of the top wall and a mouth of a person placed on the lid around the opening. The anti-suction feature minimizes formation of a complete seal between the mouth and the lid so that the person cannot establish sufficient suction to remove fluid through the opening. 
     Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.

     DETAILED DESCRIPTION 
     A package  10  in accordance with the present disclosure includes a container  12 , a dosing dispenser  14  (also referred to as a closure) coupled to a filler neck  16  of the container  12 , and a child-resistant closure-release mechanism  18  as shown, for example, in  FIG. 1 . The dosing dispenser  14  includes a lid  20  adapted to be coupled to the container  12  and includes a flip-top cap  22  that is pivotably coupled to lid  20  to conceal a syringe receiver  24 . The syringe receiver  24  is configured to accept a fluid-transfer tip of a syringe (not shown) to permit the dosing of liquid from the container  12 , as suggested in  FIG. 1 . The syringe receiver  24  may be configured as a one-way valve so as to block flow of fluid through the syringe receiver  24  absent insertion of a fluid-transfer tip of a syringe. The syringe receiver  24  may also include a valve assembly  200 ,  300 , as will be discussed in detail below. 
     The dosing dispenser  14  is configured to change from an opened position, as shown in  FIG. 1 , where the flip-top cap  22  is pivoted about a cap pivot axis  30  away from the lid  20 , and a closed position, where the flip-top cap  22  is pivoted about the cap pivot axis  30  into engagement with the lid  20  to block access to the syringe receiver  24 . The child-resistant closure-release mechanism  18  is configured to retain the flip-top cap  22  in the closed position to provide means for blocking unauthorized use of the package  10  while the flip-top cap  22  is in the closed position. The flip-top cap  22  may include a plug  33  that is inserted into the syringe receiver  24  in the closed position, as shown in  FIG. 7 . 
     The child resistant lock  18  includes a lock tab  32  coupled to the flip-top cap  22  and a tab retainer  34  coupled to the lid  20  as shown in  FIGS. 2 and 3 . The lock tab  32  includes a plate  36 , a first protuberance  38 , and a second protuberance  40 . The first and second protuberances  38 ,  40  extend outwardly away from the plate  36  in opposite directions. The tab retainer  34  includes a first rail  42  and a second rail  44  that are configured to engage selectively with the first and second protuberances  38 ,  40 , respectively, to restrict movement of the dosing dispenser  14  from the closed position to the opened position. The first and second protuberances  38 ,  40  extend outwardly slightly less than a distance which two ends  64 ,  66  of the second end wall  50  of the lid  20  extends, which will be described in detail below. 
     The container  12  is generally cylindrically shaped and includes a transition portion  15  that tapers from an outer circumferential surface of the container to the filler neck  16  as shown in  FIG. 1 . The filler neck  16  is also generally cylindrically shaped and includes an outer rib  17  that surrounds an outer circumferential surface of the filler neck  16 . The outer rib  17  is arranged such that a top surface of the rib  17  is annularly aligned with a bottom rim  21  of the lid  20  of the dosing dispenser  14  when the lid  20  is coupled to the filler neck  16 . In other embodiments, the container  12  and filler neck  16  may be shaped differently, so long as the lid  20  is capable of being coupled to the top portion of the filler neck  16 . 
     The lid  20  is coupled to the filler neck  16  of the container  12  via a threaded arrangement. In particular, the filler neck  16  includes at least one first thread  27  that extends around the circumference of the filler neck  16 , and the lid  20  includes at least one second thread  29  that corresponds to the at least one first thread  27  such that the lid  20  may be screwed onto the filler neck  16 . The lid  20  may be screwed onto the filler neck  16  until the bottom rim  21  of the lid  20  touches, or nearly touches, the outer rib  17  of the filler neck  16 . In other embodiments, the lid  20  may be coupled to the filler neck  16  using other methods, such as press fitting or adhesives, for example. 
     The flip-top cap  22  is generally annular and hollow and includes a top surface  23  and an annular wall  25  that extends axially away from the top surface  23  as shown in  FIGS. 1, 2, and 6 . The annular wall  25  extends around the circumference of the top surface  23 . The annular wall  25  may include a gap located near the pivot point  35  where the flip-top cap  22  and the lid  20  meet so as to allow the flip-top cap  22  to pivot about the cap pivot axis  30  and assume the closed position. 
     The lock tab  32  extends axially away from a portion of the annular wall  25  that is opposite the pivot point  35  where the flip-top cap  22  and the lid  20  meet. The lock tab  32  may be formed integrally with the annular rim  25 , or may be formed as a separate component that is subsequently joined to the annular rim  25 . Likewise, the first protuberance  38  and the second protuberance  40 , which extend outwardly in the circumferential direction from the plate  36 , may be integrally formed with the plate  36 , or may be separate components that are subsequently joined. The lock tab  32  may include instruction text, such as the text “PUSH IN AND UP TO OPEN”, as shown in  FIG. 2 , to inform a user how to open the flip-top cap  22 . The lock tab  32  may also include a gripable surface to allow the user to effectively grip the lock tab  32 , such as with his or her thumb, to push in and lift the lock tab  32  in order to move the lock tab  32  to the open position. The lock tab  32  may instead include ridges, ribs, or any other feature to provide a gripable surface. 
     The lid  20  of the dosing dispenser  14  is also generally annular and hollow, so as to fit over the filler neck  16 , and includes a top wall  46  having an upper surface  47 , a first side wall  48 , and a second side wall  50  as shown in  FIGS. 2-7 . The top wall  46  is formed to include an aperture  54  and has a central axis  56  that extends generally through the center of the top wall  46  through the aperture  54 , as shown in  FIG. 4 . The first side wall  48  is generally cylindrical and extends annularly around the central axis  56 . The first side wall  48  is concentric with the top wall  46  such that the top wall  46  encloses the first side wall  48 . 
     The second side wall  50  extends annularly around the first side wall  48  and is concentric with the top wall  46  and the first side wall  48 . The second side wall  50  is arranged or formed on the outer circumferential surface of the first side wall  48  as shown in  FIG. 4 . In some embodiments, the top wall  46 , first side wall  48 , and second side wall  50  may be integrally formed as a single monolithic piece. The top wall  46  and first and second side walls  48 ,  50  may also be formed as separate components that are subsequently joined together by known methods. 
     The second side wall  50  is sized to have a diameter substantially similar to a diameter of the annular wall  25  of the flip-top cap  22 . The second side wall  50  is also substantially aligned with the outer rim  31  of the flip-top cap  22 , and may extend radially the same distance as the outer rim  31 . The second side wall  50  does not extend fully to the upper surface  47  of the top wall  46 , but instead allows for a small portion of the first side wall  48  to be exposed above the second side wall  50 . Accordingly, when the flip-top cap  22  is in the closed position, the outer rim  31  will align with the top surface of the second side wall  50  and seal the flip-top cap  22 . However, in other embodiments, the diameter of the second side wall  50  may be smaller than the diameter of the annular wall  25  of the flip-top cap  22  such that, when the flip-top cap  22  is in the closed position, the annular wall  25  extends axially over at least a portion of the second side wall  50 . 
     The first side wall  48  includes a recessed portion  49  that is spaced apart from the central axis  56  a first distance  58  as shown in  FIG. 5 . The second side wall  50  is spaced apart from the central axis  56  a second distance  60  that is greater than the first distance  58 . The second side wall  50  includes a first end  64  and a second end  66  spaced apart from the first end  64  circumferentially around the central axis  56  to provide a space  68  between a first end  64  of the second end  66 . The first and second ends  64 ,  66  extend beyond respective ends  63 ,  65  of the recessed portion  49  in the circumferential direction, as shown in  FIG. 4 . Accordingly, a gap  62  is formed radially between the recessed portion  49  of the first side wall  48  and the first and second ends  64 ,  66  of the second side wall  50 . 
     The space  68  between the first and second ends  64 ,  66  of the second side wall  50  generally corresponds to the lock tab  32  in both width and location when the dosing dispenser  14  is in the closed position. The first and second rails  42 ,  44  are coupled to respective ends  64 ,  66  of the second side wall  50  and extend inwardly toward one another into the space  68 . 
     Each rail  42 ,  44  has a generally triangular shape when viewed in the circumferential direction and includes an angled outer surface  70 , an inner surface  72  and a bottom surface  74 , as shown in  FIGS. 5 and 6 . The angled outer surface  70  and inner surface  72  converge at a point  76  near the top of the second side wall  50 . The bottom surface  74  is spaced apart vertically from the point  76  and is generally perpendicular to the inner surface  72 . The angled outer surface  70  moves further from the central axis  56  as the angled outer surface  70  extends from the point  76  to the bottom surface  74 . 
     When a user desires to move the dosing dispenser  14  from the opened position to the closed position, the flip-top cap  22  may be moved about the cap pivot axis  30  toward lid  20 . As the flip-top cap  22  moves toward the lid  20 , the lock tab  32  moves into engagement with the angled outer surfaces  70  of the first and second rails  42 ,  44  at or near points  76 . As the flip-top cap  22  is moved closer to the lid  20 , the first and second protuberances  38 ,  40  slide along respective angled outer surfaces  70  and the lock tab  32  flexes outwardly away from the first side wall  48  due to the slope of the outer surfaces  70 . Once the first and second protuberances  38 ,  40  pass the bottom surfaces  74  of the first and second rails  42 ,  44 , the lock tab  32  returns to its unflexed position so that the first and second protuberances  38 ,  40  rest beneath the first and second rails  42 ,  44  and against the bottom surfaces  74  to establish the closed position. 
     The lock tab  32  may be made from polymeric materials, such as plastics, or any other flexible materials so as to allow the lock tab  32  to flex inwardly and outwardly relative to the flip-top cap  22 , as suggested in  FIG. 6 . However, the material must be resilient enough such that when the first and second protuberances  38 ,  40  pass the bottom surfaces  74  of the first and second rails  42 ,  44 , the lock tab  32  returns to its unflexed, original position. 
     When a user desires to move the flip-top cap  22  from the closed position to the opened position, the user may apply an inward force  100  on the lock tab  32  so that the lock tab  32  flexes inwardly toward the first side wall  48 . Once the first and second protuberances  38 ,  40  pass a plane defined by the inner surfaces  72  of the first and second rails  42 ,  44  and are located within the gap  62 , the user applies an upward force  102  to cause the first and second protuberances  38 ,  40  to slide upwardly through the gap  62 . From there, the flip-top cap  22  may be moved unobstructed all the way to the opened position for access to the syringe receiver  24 . 
     In other embodiments, each rail  42 ,  44  may be formed as a different shape, so long as the first and second protuberances  38 ,  40  of the lock tab  32  are capable of sliding outwardly and then locking in place under the first and second rails  42 ,  44 . For example, the outer surfaces  70  of the first and second rails  42 ,  44  may have an arc shape such that the surfaces  70  are curved from the point  76  to the bottom surface  74 . As such, the first and second protuberances  38 ,  40  may slide down along the curved outer surfaces  70  until they pass over and lock underneath the bottom surfaces  74 . 
     In some embodiments, the first and second rails  42 ,  44  are sloped in the opposite direction, or in other words, sloped towards the first side wall  48 . In this embodiment, when the lock tab  32  slides over the outer surfaces  70  of the rails  42 ,  44 , the first and second protuberances  38 ,  40  slide along the outer surfaces  70  and the lock tab  32  flexes inwardly toward from the first side wall  48  due to the slope of the outer surfaces  70 . Once the first and second protuberances  38 ,  40  pass the bottom surfaces  74  of the first and second rails  42 ,  44 , the lock tab  32  returns to its unflexed position so that the first and second protuberances  38 ,  40  rest beneath the first and second rails  42 ,  44  and against the bottom surfaces  74  to establish the closed position. 
     When a user desires to move the flip-top cap  22  from the closed position to the opened position in this embodiment, the user may pull on the lock tab  32  in order to apply a force opposite of the inward force  100  shown in  FIG. 6 . In this case, the lock tab  32  flexes outwardly away from the first side wall  48 . Once the first and second protuberances  38 ,  40  pass a plane defined by the inner surfaces  72  of the first and second rails  42 ,  44 , the user applies an upward force  102  to cause the first and second protuberances  38 ,  40  to slide upwardly. From there, the flip-top cap  22  may be moved unobstructed all the way to the opened position for access to the syringe receiver  24 . 
     The package  10  may further include a valve assembly  200 ,  300  configured to retain product in an internal region  13  of the container  12  when a syringe is not drawing the product out of the internal region  13  as shown in  FIGS. 7-15 . While valve assembly  200 ,  300  is illustratively made from a thermoplastic elastomeric material (TPE), any other suitable elastomers or plastics materials may be used in accordance with the present disclosure. 
     A first embodiment of a valve assembly  200  is shown in  FIGS. 7-9 . The valve assembly  200  includes an inlet port  202  and an upper disk  204  formed as a valve ring. The inlet port  202  provides the syringe receiver  24  and is formed to include a vertical passageway  205  that defines a central axis  201  that is aligned with the central axis  56  of the aperture  54 . The inlet port  202  may include an upper ring  203  that extends annular around the top of the inlet port  202 . The vertical passageway  205  opens selectively toward the internal region  13  of the container  12 . The upper disk  204  is coupled to the top of the filler neck  16  in a manner known in the art. The lid  20  is placed over the upper disk  204  of the valve assembly  200  when the lid  20  is coupled to the filler neck  16 , as shown in  FIG. 7 . 
     The valve assembly  200  further includes a lower disk  208  that is arranged on the underside of the upper disk  204  and is substantially concentric with the upper disk  204 . As can be seen in  FIG. 7 , the lower disk  208  is located within the internal region  13 . The lower disk  208  is formed to include a laterally extending passageway  206  that is coupled in fluid communication with the vertical passageway  205  formed in the inlet port  202 . The laterally extending passageway  206  also includes two exit holes  209 ,  210  that are in fluid communication with the interior  13  of the container  12 . The exit holes  209 ,  210  are sized as a function of the viscosity of the fluid in the bottle so as to block flow through the exit holes  209 ,  210  absent a suction force, such as from a fluid-transfer tip of a syringe. The exit holes  209 ,  210  may be formed as semi-circles, as shown in  FIG. 9 . 
     The vertical passageway  205  runs substantially transverse to the laterally extending passageway  206  as shown in  FIG. 8 . In some embodiments, the vertical passageway  205  is perpendicular to the laterally extending passageway  206 . The passageways  205 ,  206  are sized to be substantially similar to the size of the exit holes  209 ,  210 . Accordingly, the lengthened path and/or multiple narrow flow channels of the passageways  205 ,  206 , along with the exit holes  209 ,  210 , limit access to fluid in the container  12 , as well as minimizing leakage when the package  10  is disturbed, such as being shaken or turned upside down. 
     A second embodiment of a valve assembly  300  is shown in  FIGS. 10 and 11 . The valve assembly  300  includes a body  302 , an annular outer rib  304 , and an annular inner rib  306 . The body  302  provides the syringe receiver  24  and is formed to include a passageway  303  that opens selectively into the internal region  13  of the container  12 . In particular, the passageway  303  may be formed as a one-way passageway  303  so as to block flow of fluid through the passageway  303  absent a fluid-transfer tip of a syringe. In some embodiments, the valve assembly  300  may be a duck-bill valve. 
     As can be seen in  FIG. 10 , the outer rib  304  and the inner rib  306  are axially spaced apart substantially the same distance as the width of the top wall  46  of the lid  20 . Accordingly, the valve assembly  300  may be fitted into the aperture  54  in the top wall  46  so as to locate the body  302  in the aperture  54 . Similarly to the valve assembly  200  described above, the valve assembly  300  limits access to fluid in the container  12 , as well as preventing leakage even when the package  10  is disturbed, such as being shaken or turned upside down. 
     The package  10  further includes an anti-suction feature  80  arranged on the top wall  46  of the lid  20  as shown in  FIGS. 12-15 . The anti-suction feature  80  may be used with either valve assembly  200 , as suggested in  FIGS. 12 and 13 , valve assembly  300 , as suggested in  FIGS. 14 and 15 , or another suitable valve assembly. The dosing dispenser  14 , the valve  200 ,  300 , and the container  12  of the package  10  are arranged in the same manner as shown in  FIGS. 1-11 , as discussed above. The anti-suction feature  80  is configured to block a user, such as a child, from establishing a seal with the top wall  46  over the syringe receiver  24  and providing a sufficient suction force that would remove the fluid from the container  12  through the valve assemblies  200 ,  300 . 
     The anti-suction feature  80  includes a plurality of ribs  82  spaced circumferentially around the central axis  56  and extending radially away from the central axis  56  as shown in  FIGS. 13 and 15 . The plurality of ribs  82  may extend to the outer circumferential edge of the top wall  46 , or may terminate just before the outer edge, as shown in  FIGS. 13 and 15 . In the illustrative embodiment, six ribs  82  are included in the anti-suction feature  80 , however, in other embodiments, any suitable number of ribs may be used. The plurality of ribs  82  may be identically shaped, as shown in  FIGS. 13 and 15 , or may have differing shapes while still providing the gaps  84  discussed below. In the illustrative embodiment, each of the ribs  82  is spaced apart circumferentially from one another an equal distance, however, in other embodiments, any suitable spacing may be used. In yet another embodiment, the plurality of ribs  82  may be spaced circumferentially from one another by unequal distances. 
     Each of the ribs  82  includes an inner portion  86  that abuts the aperture  54  formed in the top wall  46  and a portion of the valve assemblies  200 ,  300 , and an outer portion  88  radially outward from the inner portion  86 , as shown in  FIGS. 13 and 15 . The inner portion  86  has a height from the top wall  46  that is greater than a height of the outer portion  88 . The outer portion  88  tapers downwardly toward the top wall  46  as the ribs  82  extend radially outward from the aperture  54 . In the illustrative embodiment, the outer portion  88  has a width that increases as the ribs  82  extend radially outward from the aperture  54 . Although the ribs  82  are generally triangularly shaped, the transition from the inner portion  86  to the outer portion  88  may be stepped, curved, or any other suitable shape that will allow for air to pass through the gaps  84 , as discussed in detail below. 
     The plurality of ribs  82  extend vertically away from the top wall  46  as shown in  FIGS. 13 and 15 . In the embodiment that includes the valve assembly  200 , as shown in  FIG. 13 , each inner portion  86  of the plurality of ribs  82  extends upwardly to an underside of the upper ring  203  of the valve assembly  200 . In the embodiment that includes the valve assembly  300 , as shown in  FIG. 15 , each inner portion  86  of the plurality of ribs  82  extend upwardly beyond a top surface of the outer rib  304  of the valve assembly  300 . 
     In the illustrative embodiment, the spacing between each of the ribs  82  provides gaps  84 . If a user attempts to place his or her mouth over the lid  20 , and subsequently attempts to provide a suction force to remove fluid from the container  12 , the gaps  84  allow air to flow therethrough because at least a portion of the user&#39;s mouth is spaced apart from the top wall  46  by the inner portions  86  of the plurality of ribs  82 . In this way, the plurality of ribs  82  minimize formation of a complete seal between the user&#39;s mouth and the top wall  46  of the lid  20  over the syringe receiver  24 . The plurality of ribs  82  thus provide additional safety features to the dosing dispenser  14  to minimize unwanted removal of fluid from the container  12 .
