- the windows are approximately the same size as the apertures 44 in the sidewall of section 34 of the fitment and are spaced apart by approximately the same spacing as those apertures.
- the free edge of the sidewall 80 is in the form of an inwardly extending annual ridge 90 .
- the ridge 90 is arranged to be received within an annular recess 92 extending about the outer periphery of the connector 58 of the probe to form a detent mechanism for connecting the fitment and the probe together when they are in the operative position (as well be described later).
- An annular recess 94 extends about the outer periphery of the sidewall 80 of the valve 50 .
- the recess 94 is arranged to receive the stop 48 of the fitment.
- valve 50 Operation of the valve 50 will now be described with reference to FIG. 5-7 .
- the slidable valve 50 is in the closed position like shown in FIGS. 4 and 5 .
- the valve is held in that closed position by a detent arrangement.
- the arrangement comprises the frictional engagement between the stop ridge 48 of the fitment and the annular recess 94 of the valve, i.e., the stop ridge is located within the annular recess of the valve.
- a solid portion of the sidewall 80 of the valve blocks the apertures 44 in the fitment 24 . Accordingly, the flowable contents of the bag or pouch are precluded from entering through those apertures into the fitment.
- the probe 26 When access to the flowable material is desired, the probe 26 is juxtaposed with respect to the fitment 24 , like shown in FIG. 5 , and the fitment and probe are moved relative to each other along the longitudinal axis 40 . This action causes the ball 72 of the valve 54 to be engaged by the free end 86 of the post of the valve 50 . Continued inward movement of the probe with respect to the fitment coupled with the bias provided by the spring 74 on ball 72 overcomes the frictional engagement between the ridged stop 48 and the annular recess 94 , whereupon the valve 50 is carried rearwardly until its top surface 82 engages the ridged stop 46 of the fitment.
- the probe is in the operative position with respect to the fitment and the windows 88 will be juxtaposed opposite the apertures 44 , thereby opening those apertures.
- the flowable material within the bag or pouch can flow into the fitment 24 as shown by the broken lines in FIG. 6 .
- the annular ridge 90 in the valve 50 will snap-fit into the annular recess 92 in the probe, thereby effectively connecting the probe to the slidable valve 50 .
- the length of the post 84 of the valve 50 is selected so that when the top wall of the valve 50 engages the ridged stop 46 of the fitment, as shown in FIG. 6 , the spring 74 of the valve 54 will be compressed, thereby moving the ball 72 off of the valve seat 70 . Accordingly the flowable materials entering into the fitment can now flow past the now-opened valve 54 and then through the central passageway in the probe and out through the passageway 68 in the connector 66 . From there, the flowable materials can flow into the dispensing conduit (not shown) following the path represented by the broken lines in FIG. 6 .
- the probe and fitment are pulled apart. Since the ridge 90 of the valve 50 is frictionally held within the annular recess 92 extending about the outer periphery of the connector 58 of the probe, the relative movement of the probe away from the fitment carries the slidable valve 50 down the fitment from the open position shown in FIG. 6 to the point where the ridged stop 48 of the fitment receives the annular recess 94 of the valve 50 . This action precludes the valve from any further sliding movement and holds the valve in the closed position shown in FIG. 7 , whereupon the portions of the sidewall 80 of the valve again block the apertures 44 of the fitment and the ball 72 of the valve 54 again is in sealing engagement with the valve seat 70 .
- the fitment 24 optionally includes anti-blocking features to ensure that the entire flowable contents of the package can be pumped out of the package, notwithstanding the collapse of the walls of the package as the contents are pumped out.
- FIGS. 8-10 One exemplary embodiment of such a fitment is shown in FIGS. 8-10 .
- four elongated fingers 100 project rearwardly from the inner or rear end of the tubular section of the fitment so that they are is located within the cavity 30 in the bag or pouch holding the product to be dispensed.
- Each finger 100 is an elongated member of any suitable, e.g., cruciform, shape in cross-section as shown in FIG. 10 .
- respective elongated linear ridges 102 project upward from the outer surface of section 34 contiguous with each of apertures 44 in the fitment.
- Each ridge 102 extends parallel to the longitudinal axis 40 .
- the walls 28 A and 28 B will collapse towards each other.
- the extending fingers 100 and the extending ridges 102 will prevent any portions of those walls of the bag from collapsing adjacent the fitment to the point where the collapsed walls block or otherwise impede the free flow of the flowable material into the apertures of the fitment when the valves 50 and 54 are in their open condition.
- the use of the package to dispense its contents is as follows the package 20 is placed within a drawer (not shown) of the dispensing apparatus, with the collar portion of the fitment 24 being received within a recess in the drawer to hold the package in place. The drawer with the package 20 therein is then moved to bring a probe 24 of the dispensing apparatus into the interior of the fitment, whereupon the valves 50 and 54 open as described above. The pump mechanism of the dispensing apparatus can then be operated to meter out a desired amount of the flowable material.
Abstract
A package for enabling the dispensing (metering of) a flowable material by use of dispensing apparatus is disclosed. The package is a flexible bag or pouch having an internal cavity in which the flowable material is disposed and a fitment through which the flowable material is metered. The fitment is arranged to receive a probe of the dispensing apparatus and includes a first valve to prevent the flowable material from exiting through the fitment until the fitment is connected to the probe. The probe includes a second valve which opens when the probe is connected to the fitment and which closes when the probe is disconnected from the fitment. The disconnection of the probe from the fitment causes the first valve to close. The fitment also includes an anti-blocking member which prevents the walls of the package from collapsing to block the fitment when the flowable material is metered out.
Description
- This utility application claims the benefit under 35 U.S.C. §119(e) of Provisional Application Ser. No. 61/477,824 filed on Apr. 21, 2011 entitled Fitment and Pouch for Connection to a Probe and Pump-Out Metering System. The entire disclosure of this provisional application is incorporated by reference herein.
- This invention relates to flexible packages and more particularly to flexible package systems for use with dispensing apparatus, e.g., beverage making machines, for dispensing flowable materials.
- Various soft-drink making/dispensing apparatus today make use of what is referred to as “bag-in-box” packages for holding the drink-making ingredient, e.g., syrup. In particular, the bag-in-box package includes an outer protective container (the “box”) and an inner flexible material container (the “bag”). The outlet of the package is typically in the form of a fitment which mounted on a portion of the wall of the flexible package and is in fluid communication with its interior. The fitment is arranged to be pierced by a probe forming a portion of the beverage making apparatus. The probe is connected to a flexible pipe or conduit (hereinafter referred to as the “dispensing conduit”) which forms the input to the pumping mechanism of the dispensing apparatus. When the probe has pierced the fitment and the pumping mechanism operated, the contents of the package can be pumped or metered out (dispensed). This action causes the walls of the bag to collapse as the bag's contents are pumped out. In order to ensure that the collapsing walls of the bag don't block the fitment, it is a common practice to make use of some anti-blocking device as part of the fitment or as an adjunct to the fitment.
- When all of the available contents of the package have been dispensed, the probe is disconnected from the fitment, so that a new package can then be introduced into the dispensing apparatus and its fitment connected to the probe and its associated dispensing conduit. Once that has been accomplished, the contents of the new package can be dispensed by the operation of the dispensing apparatus.
- As will be appreciated by those skilled in the art after the probe has been disconnected from the package, any contents of the package that may still be resident in the package could seep or otherwise drip out of the package through the fitment. Moreover, some residual contents may still be resident in the dispensing conduit and, if so, could leak out the disconnected end (i.e., the end at which the probe is located). Obviously, such occurrences are problematic since they make keeping the dispensing apparatus sanitary more difficult (e.g., residual syrup on portions of the dispensing apparatus could serve as a source of bacterial contamination, if the apparatus is not thoroughly cleaned).
- The subject invention is directed to addressing those problems, while also ensuring that the contents of the package cannot gain egress through the fitment until the probe of the dispensing conduit is connected to the fitment and ensuring that the contents of the package can not gain egress through the fitment when the probe is disconnected from the fitment.
- In accordance with one aspect of this invention there is provided a package for use with a probe and associated dispensing conduit arranged for connection to a dispensing apparatus, a soft-drink making machine, to dispense a flowable material, e.g., syrup, from the package. The package is in the form of a flexible bag or pouch having plural wall portions defining an internal cavity in which the flowable material is located and a fitment secured to at least one of the wall portions. The fitment is arranged to receive the probe and comprises a valve. The valve is arranged to preclude the flowable material in the bag or pouch from flowing into the fitment until the probe is operatively coupled to the fitment. The probe is arranged for connection to the fitment in an operative position, whereupon a portion of the probe cooperates with the valve of the fitment to open that valve and enable the flowable material in the bag or pouch to be metered out through the fitment. The probe includes a portion, e.g., a detent surface, arranged to be coupled to the valve of the fitment to close that valve when the probe is disconnected from the fitment, whereupon any flowable material within the bag or pouch is precluded from gaining egress through the fitment.
- In accordance with another aspect of this invention the said probe comprises a second valve arranged to be opened when the probe is connected to the fitment in the operative position, whereupon the flowable material can be metered out of the bag or pouch through the open first and second valves. The second valve is arranged to automatically close to prevent any flowable material in the probe or its associated dispensing conduit from egress through the probe when the probe is disconnected from the fitment.
- In accordance with another aspect of this invention the fitment may include at least one anti-blocking member preventing wall portions of the bag or pouch from collapsing to block the fitment when the flowable material in the bag or pouch is metered out.

FIG. 7 is a longitudinal sectional view, similar toFIG. 5 and, but showing the fitment and probe as the probe is being withdrawn (disconnected) from the fitment to prevent any further flowable material from entering into the fitment; -
FIG. 8 is an end view of an alternative embodiment of a fitment constructed in accordance with this invention, that fitment includes anti-flow blocking features; -
FIG. 9 is a top plan view of the fitment shown inFIG. 8 ; and -
FIG. 10 is an enlarged cross-sectional view taken along line 10-10 ofFIG. 9 . - Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown at 20 in
FIG. 2 an exemplary embodiment of apackage 20 having afitment 24 constructed in accordance with one aspect of this invention. Thepackage 20 is arranged for use with a dispensing apparatus (not shown), e.g., a soft-drink dispensing machine, to dispense a flowable material, e.g., syrup, therefrom. To that end, a dispensing conduit (not shown) is provided. The dispensing conduit includes aprobe 26 constructed in accordance with another aspect of this invention. Theprobe 26 is arranged to be connected to thefitment 24 so that the flowable material, e.g., a beverage making syrup, within thepackage 20 can be metered out of the package by the dispensing apparatus. Thus, the opposite end of the dispensing conduit from the end bearing theprobe 26 is arranged to be coupled to a pump or other metering device of the dispensing (metering) apparatus (not shown). - As best seen in
FIGS. 2 and 3 , thepackage 20 basically comprises a bag orpouch 22 formed of a sheet of any suitable flexible material, e.g., a plastic film of one or more plies or layers. Thepouch 22 can be of any suitable construction. One particularly suitable exemplary construction is like that shown and claimed in my U.S. Pat. No. 7,246,721, which is assigned to the same assignee as this invention and whose disclosure is incorporated by reference herein. To that end, a sheet of flexible material is folded over itself to form a pair of confronting panels orwalls side seal lines 28C and atop seal line 28D. This arrangement forms a hollow interior cavity 30 (FIG. 3 ) in which the flowable material, e.g., beverage making syrup, is located. - The
fitment 24 is fixedly secured, e.g., welded, between the top edges of the twowalls top seal line 28D to serve as the access point or port through which the contents of the package can be metered (dispensed). That action is accomplished by the introduction of theprobe 26 into the fitment, as will be described later. - The
fitment 24 is best seen inFIGS. 1 and 4 and basically comprises a generally boat-shaped base section 32, an innertubular section 34 and anouter collar section 36. Those sections are made of any suitable material, e.g., a plastic, and are preferably formed as an integral unit by any suitable method, e.g., injection molding. The boat-shaped base basically comprises a pair of diametrically opposed outwardly projectingplanar flanges 32A and a plurality of generally triangular, shaped-apartfins 32B projecting upward from theflanges 32. The top edges of the flanges serve as the points along which the walls of the pouch at theseal line 28A are affixed, e.g., welded. The inner tubular section includes acentral passageway 38 having alongitudinal axis 40 extending the length of thesection 32, the length of the boat shapedsection 34 and the length of theouter collar section 36. Theouter collar section 36 includes a pair of spaced apartcircular flanges section 34 includes plural spaced apartapertures 44 and a slightly inwardly projecting annular ridge orledge 46 at the free end of that section, as best seen inFIG. 4 . Another slightly inwardly projecting annular ridge orledge 48 is located within thepassageway 38 at the interface of thesections apertures 44. Theannular ridges valve 50 that also constitutes a portion of thefitment 24. - The details of the
valve 50 will be described later. Suffice it for now to state that the valve 50 (also to be identified as the “first valve”) is a slidable member which is located within thepassageway 38 and is slidable along thelongitudinal axis 40 between an open position shown inFIG. 6 , and a closed position shown inFIGS. 4 , 5 and 7, and vice versa. When thevalve 50 is in the closed position it is held in that position by thestop ridge 48, with a portion of the valve disposed over theapertures 44 in the fitment to block or close those apertures. This precludes the contents of the package from flowing into the fitment. When the valve is in the open position, open portions of thevalve 50 in the form of windows (to be described later) are disposed opposite to theapertures 44, thereby opening those apertures. This enables the contents of the package to flow into the fitment's central passageway. The moving of thevalve 50 from the closed to the opened position is accomplished by the introduction of theprobe 26 into thefitment 24 until the probe is at an operative position with respect to the fitment. - The
probe 26 is best seen in FIGS. 1 and 5-7. As can be seen it is in the form of an assembly comprising atubular body 52, a spring-biased, ball valve 54 (also to be identified as the “second valve”), and aflanged connector 56. The tubular body is made of any suitable material, e.g., a plastic, and is preferably formed as an integral unit by any suitable method, e.g., injection molding. It has a first end in the form of aconnector 58 and a central bore orpassageway 60 extending through the entire length of the body. The portion of the central passageway extending through theconnector 58 is of smaller inner diameter than the remaining portion of that passageway. Theflanged connector 56 includes acylindrical portion 62 which is fixedly secured within the opposite end of thecentral passageway 60 of the tubular body from theconnector 58. A pair of generallyplanar flanges cylindrical portion 62. Ahollow connector 66 projects outward from the plane of theflange 64A. Theconnector 66 is arranged to be received within the open free end of a dispensing conduit of the dispensing apparatus and includes acentral passageway 68 extending from the free end of theconnector 66 through the entire length of thecylindrical portion 62. Theflanged connector 56 is also made of any suitable material, e.g., a plastic, and is preferably formed as an integral unit by any suitable method, e.g., injection molding. The inner diameter of thepassageway 68 in flanged connector is approximately the same size as the inner diameter of thepassageway 60 extending through theconnector 58. The interface of the portion of thepassageway 60 through thebody 52 and the portion of the passageway through theconnector 58 forms a valve seat 70 (FIG. 5 ) for thevalve 54. - The
valve 54 is a spring-biased assembly comprising aball 72 and acompression spring 74. The ball is located on theseat 70 and is held in place thereon by thecompression spring 74. To that end, thespring 74 is interposed between theball 72 and arecess 76 at the inner end of thecylindrical portion 62. When thevalve 54 is in the closed position, i.e., theball 72 on thevalve seat 70, thepassageway 60 through the probe is blocked off or closed. Accordingly, any flowable materials that may be located within theprobe 26 or the dispensing conduit to which the probe is connected will be precluded from egress through thepassageway 60 by theclosed valve 54. - The
second valve 54 is arranged to cooperate thefirst valve 50 to enable the contents of the package (e.g., the flowable material) to be pumped or otherwise metered out of the package through the fitment when theprobe 26 is operatively connected to thefitment 24. In order to best understand that action a more detailed description of thevalve 50 is in order. As can be seen in FIGS. 1 and 4-7, thevalve 50 is a cup-shaped member having an outercylindrical sidewall 80 and atop wall 82. Apost 84 projects downward from the inner surface of the top wall along the centrallongitudinal axis 40. Thefree end 86 of thepost 84 is somewhat concave to engage and accommodate a portion of the surface of theball 72 of thesecond valve 54. A plurality of spaced apart openings orwindows 88 extends about the periphery of thesidewall 80 adjacent the free edge of that wall. The windows are approximately the same size as theapertures 44 in the sidewall ofsection 34 of the fitment and are spaced apart by approximately the same spacing as those apertures. The free edge of thesidewall 80 is in the form of an inwardly extendingannual ridge 90. Theridge 90 is arranged to be received within anannular recess 92 extending about the outer periphery of theconnector 58 of the probe to form a detent mechanism for connecting the fitment and the probe together when they are in the operative position (as well be described later). Anannular recess 94 extends about the outer periphery of thesidewall 80 of thevalve 50. Therecess 94 is arranged to receive thestop 48 of the fitment. - Operation of the
valve 50 will now be described with reference toFIG. 5-7 . After the bag orpouch 22 is filled with the flowable contents theslidable valve 50 is in the closed position like shown inFIGS. 4 and 5 . The valve is held in that closed position by a detent arrangement. The arrangement comprises the frictional engagement between thestop ridge 48 of the fitment and theannular recess 94 of the valve, i.e., the stop ridge is located within the annular recess of the valve. When thevalve 50 is in this position a solid portion of thesidewall 80 of the valve blocks theapertures 44 in thefitment 24. Accordingly, the flowable contents of the bag or pouch are precluded from entering through those apertures into the fitment. - When access to the flowable material is desired, the
probe 26 is juxtaposed with respect to thefitment 24, like shown inFIG. 5 , and the fitment and probe are moved relative to each other along thelongitudinal axis 40. This action causes theball 72 of thevalve 54 to be engaged by thefree end 86 of the post of thevalve 50. Continued inward movement of the probe with respect to the fitment coupled with the bias provided by thespring 74 onball 72 overcomes the frictional engagement between theridged stop 48 and theannular recess 94, whereupon thevalve 50 is carried rearwardly until itstop surface 82 engages the ridgedstop 46 of the fitment. At this point the probe is in the operative position with respect to the fitment and thewindows 88 will be juxtaposed opposite theapertures 44, thereby opening those apertures. Thus, the flowable material within the bag or pouch can flow into thefitment 24 as shown by the broken lines inFIG. 6 . In addition, theannular ridge 90 in thevalve 50 will snap-fit into theannular recess 92 in the probe, thereby effectively connecting the probe to theslidable valve 50. - The length of the
post 84 of thevalve 50 is selected so that when the top wall of thevalve 50 engages the ridgedstop 46 of the fitment, as shown inFIG. 6 , thespring 74 of thevalve 54 will be compressed, thereby moving theball 72 off of thevalve seat 70. Accordingly the flowable materials entering into the fitment can now flow past the now-openedvalve 54 and then through the central passageway in the probe and out through thepassageway 68 in theconnector 66. From there, the flowable materials can flow into the dispensing conduit (not shown) following the path represented by the broken lines inFIG. 6 . - When it is desired to disconnect the probe from the fitment, to reclose the fitment and thereby prevent any further egress of the flowable material from the bag or pouch, the probe and fitment are pulled apart. Since the
ridge 90 of thevalve 50 is frictionally held within theannular recess 92 extending about the outer periphery of theconnector 58 of the probe, the relative movement of the probe away from the fitment carries theslidable valve 50 down the fitment from the open position shown inFIG. 6 to the point where the ridgedstop 48 of the fitment receives theannular recess 94 of thevalve 50. This action precludes the valve from any further sliding movement and holds the valve in the closed position shown inFIG. 7 , whereupon the portions of thesidewall 80 of the valve again block theapertures 44 of the fitment and theball 72 of thevalve 54 again is in sealing engagement with thevalve seat 70. - Continued retraction of the
probe 26 with respect to thefitment 24 overcomes the frictional engagement of the detent formed between theridge 90 of thevalve 50 and theannular recess 92 of the probe, whereupon the probe becomes disconnected from the fitment, like shown inFIG. 5 , leaving thevalve 50 of the fitment in the closed position and leaving thevalve 54 of the probe in the closed position. Thus, any flowable material within the package is prevented from egress through the fitment. Moreover, any flowable material in probe or dispensing conduit is prevented from egress through the probe when the probe is disconnected from the fitment since theball 72 will be automatically moved back into sealing engagement with thevalve seat 70 by the bias of thespring 74. - As mentioned above, in accordance with one preferred exemplary embodiment of the invention, the
fitment 24 optionally includes anti-blocking features to ensure that the entire flowable contents of the package can be pumped out of the package, notwithstanding the collapse of the walls of the package as the contents are pumped out. One exemplary embodiment of such a fitment is shown inFIGS. 8-10 . To that end, as can be seen fourelongated fingers 100 project rearwardly from the inner or rear end of the tubular section of the fitment so that they are is located within thecavity 30 in the bag or pouch holding the product to be dispensed. Eachfinger 100 is an elongated member of any suitable, e.g., cruciform, shape in cross-section as shown inFIG. 10 . - As best seen in
FIGS. 1 and 9 respective elongatedlinear ridges 102 project upward from the outer surface ofsection 34 contiguous with each ofapertures 44 in the fitment. Eachridge 102 extends parallel to thelongitudinal axis 40. - As should be appreciated by those skilled in the art, as the flowable contents of the bag or
pouch 20 is metered out thewalls fingers 100 and the extendingridges 102 will prevent any portions of those walls of the bag from collapsing adjacent the fitment to the point where the collapsed walls block or otherwise impede the free flow of the flowable material into the apertures of the fitment when thevalves - The use of the package to dispense its contents is as follows the
package 20 is placed within a drawer (not shown) of the dispensing apparatus, with the collar portion of thefitment 24 being received within a recess in the drawer to hold the package in place. The drawer with thepackage 20 therein is then moved to bring aprobe 24 of the dispensing apparatus into the interior of the fitment, whereupon thevalves - Without further elaboration the foregoing will so fully illustrate my invention that others may, by applying current or future knowledge, adopt the same for use under various conditions of service.
