Definitions

  • the present invention deals with a container of the type defined in the preamble of attached claim 1.
  • the present invention is a container for the transportation of bulk liquid materials. More particularly, the present invention is a 208,2 l (55 gallon) drum having an inner, disposable liner which is heat sealed at an aperture in its upper end to a bung which in turn may be secured to a fill opening in the top wall of the drum.
  • the liner conforms in shape to the shape of the inner surfaces of the tank and, upon being emptied, the liner collapses and is easily removed from the drum through the fill opening.
  • U.S. Patent No. 4,044,912 discloses a container including a rigid outer tank having a collapsible bag liner for retaining viscous substances such as grease.
  • a vane shaped spacer is disposed within the bag to provide a skeletal structure about which the bag can collapse as the viscous substances are removed. The skeletal structure thereby ensures a more complete evacuation of the viscous material contained in the tank.
  • GB-B-648 863 discloses a container with the features of the preamble of attached claim 1, wherein the cylindrical extension of the top wall of the outer drum has an inner thread being engaged by an outer thread of a first bung.
  • This first bung has a central opening with an inner thread which is engaged by an outer thread of a second bung.
  • the edge portion of the liner defining its aperture has a semi-circular cross-section and is bonded to a lower recessed portion of the outer circumferential surface of the first bung.
  • the present invention provides for a drum which may be used to transport a bulk liquid material without having to be cleaned prior to such use, and has a disposable liner for the transportation of bulk liquid materials. It also provides a drum which allows for easy removal of the liner through an opening formed in the top wall of the drum.
  • the present invention provides for a 208,2 l (55 gallon) drum which may be formed of a plastic or metal and has two openings formed in its top wall.
  • a plastic liner is disposed within the drum and has formed therein two apertures which are substantially aligned with the openings. At one aperture, a portion of the liner extending therearound is heat sealed to an outer bung which is then threaded into the appropriate opening.
  • the body of the outer bung extends through the opening and has a threaded central opening which provides access to the interior of the liner.
  • An inner bung is then positioned in the threaded opening of the outer bung to seal the drum.
  • the liner collapses and is readily removed from the drum through one of the openings formed in the top wall.
  • the present invention facilitates the removal of the transported materials, the disposal of residue after discharge and the elimination of cleaning prior to reuse.
  • the liner may be disposed of through burial, incineration or recycling, no large quantities of water are needed for cleaning purposes.
  • Figure 1 is a plan view of a bulk liquid material transportation container incorporating the principles of the present invention.
  • Figure 2 is a sectional view taken substantially along line 2-2 in Figure 1 illustrating the position of the liner within the drum when filled with a bulk liquid material.
  • Figure 3 is an enlarged sectional view of a portion of Figure 2 detailing one of the openings of the container.
  • Figure 4 is an enlarged sectional view of a portion of Figure 2 illustrating the embodiment of the liner and bung construction of the present invention applied to the other opening of the container.
  • FIG. 1 illustrates a plan view of a container 10 embodying the principles of the present invention.
  • An outer drum 12 in the shape of a standard 208,2 l (55 gallon) drum, is formed of metal, plastic or other material and includes a base 14, upright side walls 16 and a top wall 18 which combine to define a central cavity 19. Formed in the top wall 18 and rising thereabove are two ports or openings 20 and 22.
  • the top wall is further provided with a rim 24 designed to prevent damage to the openings 20 and 22.
  • the liner 26 Disposed within the central cavity 19 of the drum 12 is a liner 26.
  • the liner 26 is constructed of a thin plastic material having a thickness approximately three times that of a common household garbage bag.
  • Two apertures 28 and 30 are formed in the top of the liner 26 and are substantially aligned with the openings 20 and 22 of the drum 12.
  • the container 10 is illustrated as having two openings 20 and 22, the present invention could also be constructed with a single opening.
  • a 208,2 l (55 gallon) drum provided with two openings is standard within the industry and permits all of the normal operations required of the drum 12.
  • the larger 20 of the two openings 20 and 22 is generally used for filling and emptying the container 10 while the smaller of the openings 22 is typically used as a vent opening.
  • the liner 26 of the present invention When the liner 26 of the present invention is to be incorporated into a drum 12 having two openings 20 and 22, a portion 27 of the liner 26 defining one of the two apertures 28 and 30 is fixably secured to an outer bung 32.
  • the outer bung 32 may be formed of rigid plastic or similar material. In that the outer bung 32 is also formed of plastic, this securement can be achieved by heat sealing or welding the liner 26 to the outer bung 32.
  • FIG. 2 to 4 Two bung structures are shown in Figures 2 to 4; however, only one of the openings 20 or 22 will incorporate an embodiment of the invention at a given time.
  • the present invention may be incorporated into either of the two openings 20 or 22, however, for the sake of clarity, in the drawings only opening 22 is shown as incorporating the present invention. Nevertheless, where appropriate, corresponding features of the bung structures of openings 20 and 22 have been given like designations in Figures 3 and 4.
  • the portion 27 of the liner 26 forming the larger aperture 28 is heat sealed to a lower portion 34 of the outer bung 32.
  • the outer bung 32 includes a cylindrical body 40 which extends downward through the opening 20 thereby constricting the opening 20.
  • outer bung 32 does not fully constrict the opening 20 in that a threaded portion 41 of the cylindrical body 40 defines an access opening 39 to the interior of the liner 26.
  • Integrally formed with the cylindrical body 40 is an outwardly extending flange 36 which engages an upper portion 38 of the opening 20. The resting engagement of the flange 36 with the upper surface 38 of the opening 20 thus supports and prevents the outer bung 32 and attached liner 26 from passing through the opening 20 and into the cavity 19 of the drum 12.
  • the liner 26 is installed in the drum 12 by inserting it through the opening 20. When the liner 26 is fully inserted, the flange 36 of the outer bung 32 will engage the upper surface 38 of the opening 20 and support the liner 26 hanging therebelow in the central cavity 19. To align the second aperture 30 with the remaining opening 22, the liner 26, along with the outer bung 32, is rotated.
  • the second aperture 30 may be secured to the drum 12 by various methods. One possible method is to draw the portion defining the aperture 30 up through the second opening 22 and securing it therearound by means of a threaded engagement with a cap or conventional bung.
  • the outer bung 32 of the opening 20 is secured to said opening formed in the top wall 18 by providing an interiorly threaded closure cap 42 which engages the exterior threads of the opening 20. Upon full engagement, the flange 36 of the outer bung 32 is securely retained between the upper surface 38 of the opening 20 and the cap 42.
  • the closure cap 42 is also provided with an central opening 44.
  • the opening 44 permits the contents of the container 10 to be accessed while the outer bung 32 is retained securely in position.
  • an inner bung 46 is provided which engages the threaded portion 41 of the cylindrical body 40.
  • the side walls 16 or top wall 18 of the drum 12 may be further provided with vent openings (not shown) to allow air contained between the drum 12 and the liner 26 to evacuate during filling and expansion of the liner 26.
  • the cap securing the second aperture 30 in position may be provided with a vent opening which permits the evacuation of air from the liner 26 itself.
  • the container 10 can be constructed without a second opening 22.
  • the liner 26 may be provided with a tab (not shown) designed to fit into a corresponding tab opening (not shown) and thereby secure the liner 26 during filling of the container 10.
  • both bung openings 20 and 22 of the container 10 may be completely sealed or provided with a vent opening 48.
  • One such vent opening 48 is illustrated on the inner bung 46 of Figure 3 and another is further described below in the description of the preferred embodiment, of the invention.
  • FIG. 4 illustrates a bung structure 50 where the cap, flange and cylindrical body are integrally formed to produce an outer bung or bulkhead 52.
  • the portion 27 of the liner 26 forming the aperture 28 is heat sealed to the outer surface of an inner cylindrical body 54 haying an access opening 55 with internal threads 56.
  • the cylindrical body 54 is integrally formed with an overhang structure 58 having internal threads 60.
  • the liner 26 Prior to the engagement of the threads 60 with those of the opening 20, the liner 26 must be oriented so that, upon full engagement of the overhang structure 58 and the opening 20, the second aperture 30 will be in alignment with the second opening 22.
  • the liner 26 may be provided with a tab (not shown) for securing the liner 26 during filling.
  • an inner bung 62 is provided which engages the inner cylindrical body 54 and restricts the access opening 55.
  • the inner bung 62 may be further provided with an interiorly threaded opening 64 capable of acceptance of a threaded vent means 66 to further restrict the opening 20.
  • the vent means 66 is opened by rotating a vent plug 68 some amount until the container 10 vents through the engagement of the threaded opening 64 and the vent plug 68.
  • the materials contained therein may be extracted by removing the inner bung 46 (or 62) and engaging a suction pump (not shown) with the outer bung 32 (or 52).
  • a suction pump not shown
  • the second aperture 30 may be released from the second opening 22 and the outer bung 32 (or 52) disengaged from the first opening 20.
  • the liner 26 may then be removed through the first opening 20 and disposed of properly. The insertion of a new liner 26 immediately enables the container 10 for reuse.
