Definitions
- This invention relates generally to "bag-in-the-box" containers for flowable materials such as liquids, powders and the like and more particularly, concerns the provision of an improved closure plug and a connector fitting adapted to be coupled thereto, said closure plug having internal dislodgeable means blocking access to the contents of the container, but offering access when dislodged by means applied from the exterior of the container.
- Packaging of flowable materials such as liquids, powders and the like for direct dispensing thereof offers many difficulties, particularly if the materials are valuable, odiferous, corrosive or possessed of other noxious or disagreeable characteristics. Further, it often is desired that the container for such materials not only must be sealed but must be capable of being completely emptied of its contents, i.e., dispensed to the last drop. In many applications, throwaway packages are preferred to reduce waste and to obviate disposal problems in storing and disposal of containers of the rigid or semi-rigid category.
- bag-in-the-box packaging concepts involve the packaging of the flowable materials in flexible bags which themselves are disposed within corrugated paperboard containers for dispensing of the contents. These filled bags generally take the shape of the paperboard container within which they are disposed and are supported therein by the interior walls.
- bag-in-a-box containers have found wide acceptance in the packaging of flowable powders, corrosive liquids, printing inks, dyes, milk, etc., but require security against leakage during transit and handling. Coupling to the dispensing system must assure that the flowable material does not escape from the package and/or the connection to the system. Improved provision for security should be afforded but without significant increase in cost.
- the invention provides a sealed closure for a flexible container for flowable material such as liquids and powders, the container having a filling spout sealed to a wall thereof, said closure including a unitary generally cylindrical tubular body having opposite ends, said body having an annular flange at one end and a transverse wall across the interior of said body at the opposite end, said transverse wall having a through passage and an elongate tube disposed within the body unitary with said transverse wall and about said passage, said tube extending generally parallel to the axis of said body, said tube having an entrance opening to said one end thereof and an outlet opening to the opposite end, characterized in that a dislodgeable plug is sealingly seated within said tube closing off the entrance, and a removable cap seated over said tube closing off the outlet, said plug being dislodgeable as a result of manipulation there against from the exterior of said closure.
- the invention further provides a connect or fitting adapted sealingly to receive said tube and having a plunger receivable through said tube for dislodging said plug.
- the invention to be described herein comprises a closure plug and a connector fitting for use on a flexible dispensing container, i.e., a flexible bag seated within a box normally formed of corrugated paperboard, the bag holding packaging flowable materials such as liquids (ink, dyes, corrosive material) and powders.
- the closure plug is snap-fitted or otherwise tightly coupled to the flanged filling spout which is sealed to a wall of the flexible bag and is commonly passed through a wall of the box.
- the connector fitting is adapted to be coupled to the closure plug and is provided with means for gaining access to the interior of the bag via the closure plug.
- the fitting also is provided with means for coupling a conduit thereto for directing the flow of the material to a predetermined destination.
- the closure plug includes a flanged cylindrical hollow body having a transverse wall interior thereof adjacent one end of the body. An opening is formed in said transverse wall and an interior, tapered discharge tube is integral with said wall and surrounds said openings, extending generally parallel to the axis of the body toward the opposite end of the body. A plastic flanged cup-like sealing plug is seated in the inner end of the discharge tube and a cap is secured over the narrower outer end thereof.
- the discharge tube need not be tapered but the sealing plug must be of a configuration enabling the fluid pressure interior of the bag to force the sealing plug tightly therein.
- the connector fitting is provided with means for sealingly accommodating the tapered discharge tube of the closure cap. Exterior means also are provided for gaining access to the interior of the flexible container by selective dislodgement of the cup-like plug from the inner end of the tapered discharge tube by manipulation originating from the exterior of the closure plug.
- a conduit can be coupled to the fitting to direct the flowing material to a destination, say a dispensing system or the like.
- a typical bag-in-a-box container 10 is illustrated as comprising a flexible bag 12 formed by hermetically sealing the edges of a pair of superposed sheets of metallized plastic and liner.
- One wall 14 of bag 12 has an access opening 16 and carries a flanged spout 18 sealed thereto surrounding the opening 16.
- the flanged spout 18 includes an outwardly extending multiflanged tubular portion 20 which is adapted to be pulled through a suitable passage 20 formed in wall 24 of the box 26 which preferably is formed of corrugated paperboard material.
- the spout 18 is closed by force fitting, as by a snap-in connection, of the closure plug 30.
- the closure plug 30 has an externally ribbed cylindrical tubular body 32 with an annular flange 33 at one end and a transverse wall 34 at its opposite end 36.
- a unitary transverse wall 34 includes a central opening 38 and an elongate hollow discharge tube 40 is formed as an unitary part of said wall 34 surrounding the opening 38 and extending interior of the body 32 generally concentric with and parallel to the axis thereof.
- the tube 40 is tapered in a direction so that the narrow portion is located at the delivery or outer end 42 of the discharge tube 40.
- the chamber 44 interior of the tube 40 is likewise tapered to place the narrow opening 42' adjacent the opening of body 32.
- a flanged cup-like sealing plug 46 preferably tapered, is seated tightly in the entrance 48 of the chamber 44 while a cap 50 is force-fitted over the delivery end 42 of discharge tube 40.
- the sealing cap 50 is slightly tapered to conform to the configuration of the discharge tube 40 at its end 42 so that it sealably receives said tapered delivery end 42.
- An additional function of the cap 50 is to prevent dirt or other foreign material from entering the chamber 44 from the exterior of the plug 30.
- the cap 50 also serves to protect against the unauthorized use of a foreign object to gain access to the plug 46 for the purpose of dislodging same and tapping into the content of the bag 12.
- the tapered fit between the discharge tube 40 and the internal plug 46 achieves a tight effectively self-sealing engagement against increased pressure due to sudden surges resulting from handling and impact during manipulation of the package or from a pressure build-up interior of the flexible bag 12 occuring when the same is placed under adverse pressure and/or environmental conditions.
- the annular flange 47 on plug 46 servies as a stop limit to prevent its being forced through the interior 44 of tube 40 by excess pressure interior of the bag 12.
- the closure plug 30 assembled with the plug 46 and cap 50 is coupled to the flexible bag 12 by effecting a force-fit within the spout 18 after the bag 12 is filled with the flowable material and the flange 33 abuts tightly against the spout 18.
- the plug 30 can rest against the interior of wall 24 of exterior box 26.
- the package 10 now is suitable for shipping and storage.
- a punch-out wall portion (not shown) can be provided and the spout 18 pulled through same.
- tapping connector fitting 60 adapted to be coupled sealably to the closure plug 30 for gaining access to the contents of the bag 12 and directing such contents to a predetermined location, say removed from the package.

- the inner diameter of the sealing ring 76 is selected to be slightly less than the greater diameter of the tapered discharge tube 40 of the closure plug 30.
- the plunger 70 is received within the tube 40 and the end 86' of rod 86 forced against the plug 48 to dislodge same, thereby gaining access to the flowable material within the flexible bag 12 overcoming the pressure exerted by the fluid content of the bag.

Abstract
Description
- This invention relates generally to "bag-in-the-box" containers for flowable materials such as liquids, powders and the like and more particularly, concerns the provision of an improved closure plug and a connector fitting adapted to be coupled thereto, said closure plug having internal dislodgeable means blocking access to the contents of the container, but offering access when dislodged by means applied from the exterior of the container.
- Packaging of flowable materials such as liquids, powders and the like for direct dispensing thereof offers many difficulties, particularly if the materials are valuable, odiferous, corrosive or possessed of other noxious or disagreeable characteristics. Further, it often is desired that the container for such materials not only must be sealed but must be capable of being completely emptied of its contents, i.e., dispensed to the last drop. In many applications, throwaway packages are preferred to reduce waste and to obviate disposal problems in storing and disposal of containers of the rigid or semi-rigid category.
- The development of the so-called "bag-in-the-box" packaging concepts have met with considerable success in providing solutions to the above dispensing packaging difficulties. The "bag-in-the-box" concepts involve the packaging of the flowable materials in flexible bags which themselves are disposed within corrugated paperboard containers for dispensing of the contents. These filled bags generally take the shape of the paperboard container within which they are disposed and are supported therein by the interior walls.
- Use of such containers enables reduction both in bulk and weight, as well as affords the convenience of maximum apace utilization for shipping.
- "Bag-in-the-box" packaging generally has become popular because it enables dispensing without retention of much material in the container.
- The aforementioned bag-in-a-box containers have found wide acceptance in the packaging of flowable powders, corrosive liquids, printing inks, dyes, milk, etc., but require security against leakage during transit and handling. Coupling to the dispensing system must assure that the flowable material does not escape from the package and/or the connection to the system. Improved provision for security should be afforded but without significant increase in cost.
- Accordingly the invention provides a sealed closure for a flexible container for flowable material such as liquids and powders, the container having a filling spout sealed to a wall thereof, said closure including a unitary generally cylindrical tubular body having opposite ends, said body having an annular flange at one end and a transverse wall across the interior of said body at the opposite end, said transverse wall having a through passage and an elongate tube disposed within the body unitary with said transverse wall and about said passage, said tube extending generally parallel to the axis of said body, said tube having an entrance opening to said one end thereof and an outlet opening to the opposite end, characterized in that a dislodgeable plug is sealingly seated within said tube closing off the entrance, and a removable cap seated over said tube closing off the outlet, said plug being dislodgeable as a result of manipulation there against from the exterior of said closure.
- The invention further provides a connect or fitting adapted sealingly to receive said tube and having a plunger receivable through said tube for dislodging said plug.
- The preferred embodiments of this invention now will be described, by way of example, with reference to the drawings accompanying this specification in which:
- Figure 1 is a partially exploded perspective view of a package comprising a flexible bag seated within a corrugated paperboard box with a flanged filling spout secured to the wall of the bag and passing through a wall of the box, the sealing plug of the invention being secured thereon and illustrated on one side for ease in viewing;
- Figure 2 is an enlarged sectional view of the flanged filling spout with the sealing plug according to the invention installed therein;
- Figure 3 is a longitudinal sectional view of a connector fitting for coupling the package to a dispensing system;
- Figure 4 is a view similar to Figure 3 but illustrating a modified connector fitting;
- Figure 5 is an end view of the fitting illustrated in Figure 4;
- Figure 6 is a fragmentary longitudinal section illustrating a further modification of the connector fitting;
- Figure 7 is an enlarged end view of the fitting illustrated in Figure 6; and
- Figure 8 is a diagrammatic sectional view of the installed filling spout closure plug and connector fitting illustrating a security spring lock installed thereon.
- The invention to be described herein comprises a closure plug and a connector fitting for use on a flexible dispensing container, i.e., a flexible bag seated within a box normally formed of corrugated paperboard, the bag holding packaging flowable materials such as liquids (ink, dyes, corrosive material) and powders. The closure plug is snap-fitted or otherwise tightly coupled to the flanged filling spout which is sealed to a wall of the flexible bag and is commonly passed through a wall of the box. The connector fitting is adapted to be coupled to the closure plug and is provided with means for gaining access to the interior of the bag via the closure plug. The fitting also is provided with means for coupling a conduit thereto for directing the flow of the material to a predetermined destination.
- The closure plug includes a flanged cylindrical hollow body having a transverse wall interior thereof adjacent one end of the body. An opening is formed in said transverse wall and an interior, tapered discharge tube is integral with said wall and surrounds said openings, extending generally parallel to the axis of the body toward the opposite end of the body. A plastic flanged cup-like sealing plug is seated in the inner end of the discharge tube and a cap is secured over the narrower outer end thereof. The discharge tube need not be tapered but the sealing plug must be of a configuration enabling the fluid pressure interior of the bag to force the sealing plug tightly therein.
- The connector fitting is provided with means for sealingly accommodating the tapered discharge tube of the closure cap. Exterior means also are provided for gaining access to the interior of the flexible container by selective dislodgement of the cup-like plug from the inner end of the tapered discharge tube by manipulation originating from the exterior of the closure plug. A conduit can be coupled to the fitting to direct the flowing material to a destination, say a dispensing system or the like.
- Referring to Figure 1, a typical bag-in-a-box
container 10 is illustrated as comprising aflexible bag 12 formed by hermetically sealing the edges of a pair of superposed sheets of metallized plastic and liner. Onewall 14 ofbag 12 has an access opening 16 and carries a flanged spout 18 sealed thereto surrounding the opening 16. The flanged spout 18 includes an outwardly extending multiflanged tubular portion 20 which is adapted to be pulled through a suitable passage 20 formed inwall 24 of thebox 26 which preferably is formed of corrugated paperboard material. The spout 18 is closed by force fitting, as by a snap-in connection, of the closure plug 30. - The
closure plug 30 has an externally ribbed cylindricaltubular body 32 with anannular flange 33 at one end and atransverse wall 34 at itsopposite end 36. A unitarytransverse wall 34 includes acentral opening 38 and an elongatehollow discharge tube 40 is formed as an unitary part ofsaid wall 34 surrounding the opening 38 and extending interior of thebody 32 generally concentric with and parallel to the axis thereof. Thetube 40 is tapered in a direction so that the narrow portion is located at the delivery orouter end 42 of thedischarge tube 40. Thechamber 44 interior of thetube 40 is likewise tapered to place the narrow opening 42' adjacent the opening ofbody 32. A flanged cup-like sealing plug 46, preferably tapered, is seated tightly in theentrance 48 of thechamber 44 while acap 50 is force-fitted over thedelivery end 42 ofdischarge tube 40. The sealingcap 50 is slightly tapered to conform to the configuration of thedischarge tube 40 at itsend 42 so that it sealably receives saidtapered delivery end 42. An additional function of thecap 50 is to prevent dirt or other foreign material from entering thechamber 44 from the exterior of theplug 30. - The
cap 50 also serves to protect against the unauthorized use of a foreign object to gain access to theplug 46 for the purpose of dislodging same and tapping into the content of thebag 12. The tapered fit between thedischarge tube 40 and theinternal plug 46 achieves a tight effectively self-sealing engagement against increased pressure due to sudden surges resulting from handling and impact during manipulation of the package or from a pressure build-up interior of theflexible bag 12 occuring when the same is placed under adverse pressure and/or environmental conditions. Theannular flange 47 onplug 46 servies as a stop limit to prevent its being forced through theinterior 44 oftube 40 by excess pressure interior of thebag 12. - The closure plug 30 assembled with the
plug 46 andcap 50 is coupled to theflexible bag 12 by effecting a force-fit within the spout 18 after thebag 12 is filled with the flowable material and theflange 33 abuts tightly against the spout 18. Theplug 30 can rest against the interior ofwall 24 ofexterior box 26. Thepackage 10 now is suitable for shipping and storage. A punch-out wall portion (not shown) can be provided and the spout 18 pulled through same. - For use, a tapping connector or fitting is provided. Referring to Figure 3, there is illustrated tapping connector fitting 60 adapted to be coupled sealably to the
closure plug 30 for gaining access to the contents of thebag 12 and directing such contents to a predetermined location, say removed from the package. Thefitting 60 comprises abody 62 having an interiorconical chamber 64 conforming generally to the configuration of thetapered discharge tube 40 and extending toward theopposite end 66 of thebody 62. A threadedpassage 68 is formed inbody 62 opening to theopposite end 66 of thebody 62 and carries suitable threading for reception therethrough ofplunger 70 having an enlarged threadedinner end 72 having an enlargedhead 74.Resilient sealing ring 76 is seated ingroove 78 formed adjacent the entrance tochamber 64. Aradial passage 80 is formed inbody 62 to communicate with the interior of theinternal passageway 68 and opens to threadedsocket 82 capable of receiving a threadedmale coupling 84. Theplunger 70 comprises acylindrical rod 86 which is disposed coaxially within thechamber 64 andpassageway 68 and extends outward of the entrance toconical chamber 64. The inner diameter of thesealing ring 76 is selected to be slightly less than the greater diameter of thetapered discharge tube 40 of theclosure plug 30. When the connector fitting 60 andplug 30 are assembled by removing thecap 50 and force-fitting tube 40 into thetapered chamber 64, the O-ring 76 is sealingly engaged against the outer wall of saiddischarge tube 40. Theplunger 70 is received within thetube 40 and the end 86' ofrod 86 forced against theplug 48 to dislodge same, thereby gaining access to the flowable material within theflexible bag 12 overcoming the pressure exerted by the fluid content of the bag. The outer diameter of thebody 62 coextensive with thechamber 64 is selected to be slightly less than the inner diameter of thebody 32 andclosure plug 30. - Figure 4 illustrates a modified fitting 60' wherein the plunger 70' is integral with the fitting body 62' and the threaded socket 68' is formed concentric with the chamber 64'. Fitting 62' has a relatively short,
axial passageway 94 therein eccentric relative to the central axis of the conical chamber 64' in fitting body 62' as an extension thereof communicating to the socket 68'. The plunger 70' is formed integral with the fitting body 62' and extends at its free end a predetermined distance outward of the entrance to chamber 64'. The body 62' is forced into thewall 96 defined between thetube 40 and the inner wall ofbody 32 of theclosure 30. When the body 62' is seated on saidtube 40, the plunger 70' has forced theplug 46 from the entrance tochamber 44 oftube 40. The discharge of the contents of thebag 12 is effected through the concentric opening 68'. The flow from thedischarge tube 40 is by way of the short,axial passageway 94. The internal O-ring 76 of fitting 60 is not required. The relationship of the passageways is illustrated in Figure 5. - Figure 6 illustrates another modified connector fitting, here represented by fitting 60". Fitting 60" differs from
fittings 60 and 60' in that thebody 62" of fitting 60" has an outer tapered portion, with theplunger 70" being unitary with the narrow end of thebody 62".Axial openings 102 are formed in thebody 62" adjacent the junction ofplunger 70" therewith, said one ormore openings 102 extend as internal coaxial passageways 94'. The passageways 94' terminate in rearwardly opening threadedsocket 104. There is inserted a plug 105 having symmetrically arranged ribs or flutes 106. Axial passageways 94' are defined between the resultant ribs orflutes 106 and are eccentric relative to the center of the fitting 60". - In Figure 9 there is illustrated the
safety locking clip 92 installed positively to resist vibrational and other axial forces tending to separate the respective fittings from their engagement with theclosure plug 30. An annular groove orgrooves 88 is provided in the portion of thebody 62 which is exterior of theclosure plug 30 when the fitting is fully engaged therein. The groove orgrooves 88 cooperate withgroove 90 formed in exterior of the spout 18 to enableU-shaped safety clip 92 to be seated in one of said outer selectedgrooves 90 and theannular groove 88 formed in thefitting body 60 for effecting a positive locking engagement.Clip 92 may be formed as a spring clip. Other retaining means can be applied to maintain the engagement of fitting 60 and closure plug 30 and spout 18. The circumferential surfaces of all the fitting bodies of the fittings which are illustrated herein are provided with the aforementioned outer rings orgrooves 88 or their equivalent. The rings formed in the spout members serve to engage thewall 14 about a circular opening formed in the wall of saidouter container 16 through which the flanged spout member 18 is pulled when seating same. - This engagement maintains the position of the filling flanged spout member and facilitates the use of the container. The safety lock is shown as a
U-shaped spring element 92 either formed as a metal stamping or a wire form that is radially engaged, agroove 80 in the fitting 60 and one of thegrooves 90 on the flanged spout 18 which may be available. When applied, relative motion between said spout and fitting 60 is materially resisted. When the safety lock element is formed of spring metal, the cantilever spring action provided exerts a positive clamping force therebetween. The wire form, for example, can even be made captive on one of the grooves of the fitting 60 with the free portion thereat capable of being secured onto the spout and anchored into asuitable groove 90 formed thereon. - The bag-in-
a-box 10 is illustrated oriented on one side but in use, preferably is disposed in a canted rack (not shown) with the spout 18 facing downward,wall 24 functioning as the bottom wall, so thatcontainer 12 can be substantially fully emptied of its content.
