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 fitting 60 comprises a body 62 having an interior conical chamber 64 conforming generally to the configuration of the tapered discharge tube 40 and extending toward the opposite end 66 of the body 62.
  • a threaded passage 68 is formed in body 62 opening to the opposite end 66 of the body 62 and carries suitable threading for reception therethrough of plunger 70 having an enlarged threaded inner end 72 having an enlarged head 74.
  • Resilient sealing ring 76 is seated in groove 78 formed adjacent the entrance to chamber 64.
  • a radial passage 80 is formed in body 62 to communicate with the interior of the internal passageway 68 and opens to threaded socket 82 capable of receiving a threaded male coupling 84.
  • the plunger 70 comprises a cylindrical rod 86 which is disposed coaxially within the chamber 64 and passageway 68 and extends outward of the entrance to conical chamber 64.
  • 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.
  • the outer diameter of the body 62 coextensive with the chamber 64 is selected to be slightly less than the inner diameter of the body 32 and closure 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 the wall 96 defined between the tube 40 and the inner wall of body 32 of the closure 30.
  • FIG. 6 illustrates another modified connector fitting, here represented by fitting 60".
  • Fitting 60" differs from fittings 60 and 60' in that the body 62" of fitting 60" has an outer tapered portion, with the plunger 70" being unitary with the narrow end of the body 62".
  • Axial openings 102 are formed in the body 62" adjacent the junction of plunger 70" therewith, said one or more openings 102 extend as internal coaxial passageways 94'.
  • the passageways 94' terminate in rearwardly opening threaded socket 104.
  • a plug 105 having symmetrically arranged ribs or flutes 106.
  • Axial passageways 94' are defined between the resultant ribs or flutes 106 and are eccentric relative to the center of the fitting 60".
  • FIG. 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 the closure plug 30.
  • An annular groove or grooves 88 is provided in the portion of the body 62 which is exterior of the closure plug 30 when the fitting is fully engaged therein.
  • the groove or grooves 88 cooperate with groove 90 formed in exterior of the spout 18 to enable U-shaped safety clip 92 to be seated in one of said outer selected grooves 90 and the annular groove 88 formed in the fitting 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 or grooves 88 or their equivalent.
  • the rings formed in the spout members serve to engage the wall 14 about a circular opening formed in the wall of said outer container 16 through which the flanged spout member 18 is pulled when seating same.
  • 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, a groove 80 in the fitting 60 and one of the grooves 90 on the flanged spout 18 which may be available.
  • 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 a suitable 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 that container 12 can be substantially fully emptied of its content.
