Definitions

  • the invention relates to a lidded container for storing and transporting in particular hazardous liquid fill goods, having an outer container body, an upper container lid and an inserted thin-walled inliner.
  • the container lid has at least one filling and emptying opening that can be closed in a gas and fluid tight manner and that, for example, can be secured by means of a U-shaped tension ring closure or without tension ring as a snap cover by means of snap closure or a screw cap by means of screw closure on the upper container opening of the container body on a correspondingly designed flange edge.
  • Liquids in particular hazardous liquid fill goods such as chemicals or the like, are typically filled in steel or plastic bunged drums.
  • These steel or plastic bunged drums have a special UN approval in order to allow transport and storage of hazardous liquids therein.
  • UN approval In order to receive a UN approval for drums, these drums have to pass certain tests (e.g. diagonal drop test, low-temperature drop test, internal pressure test, compression test, etc.) and meet particularly high performance standards.
  • lidded drums with UN approvals are already in existence which can be used, however, only for less hazardous liquids because a lidded drum (open top drum) is understandably not capable to have and meet the high drop strength and internal pressure resistance like a bunged drum (closed head drum).
  • the invention is based on the recognition that typically filled lidded containers—even with inserted inliners—can be used for hazardous liquids only to a limited extent, because of their exposure to high stress in the connection region from outer container body and upper container lid in the event of a drop of the container—in particular at a critical diagonal drop, causing frequently leakage—in particular when lidded plastic drums with tension ring closure of steel are involved, so that the range of applications of lidded drums is limited to non-hazardous particulate or pasty fill goods.
  • this object is attained by providing the container lid with at least one smaller lid opening, which can be closed by means of a lid closure in a gas and liquid tight manner, for filling and withdrawal of the fill goods, and by securing or fixing the thin-walled inliner on the bottom side of the container lid in the outer peripheral region in a gas and liquid tight manner, with container lid and inliner forming a gas and liquid tight hollow body unit.
  • a fully closed container for receiving the liquid fill goods and is comprised with respect to a liquid tightness of the two essential components, inliner and container lid, which are non-detachably connected to one another in a gas and liquid tight manner.
  • Filling and emptying takes place exclusively via one or two small bung openings (e.g. 2 inch opening) in the container lid which in turn are closeable by respective screw caps or bung plugs in a gas and liquid tight manner.
  • the lower container body does no longer directly participate in the sealing of the liquid fill goods and has essentially only a support function. As the container body no longer comes into contact with the liquid fill goods, it is eminently suitable for multiple use.
  • the container body may be made of thermoplastic material (e.g. HD-PE) and manufactured by injection molding process, blow-molding process, or according to the rotational molding process.
  • the container body may, however, also be made of metal (e.g. steel sheet) or wound kraft paper (cardboard drum, fiber drum).
  • the lidded container according to the invention is now able to resist also—just like a bunged drum—significantly higher internal pressures in comparison to conventional lidded drums because the liquid-tight seal toward the container interior is realized no longer via a sealing ring placed on the outer circumference in relation to the container opening of great diameter but only on the significantly smaller bung closure (2 inch) or screw lid (e.g. 150 mm diameter) within the container lid.
  • a sealing ring placed on the outer circumference in relation to the container opening of great diameter but only on the significantly smaller bung closure (2 inch) or screw lid (e.g. 150 mm diameter) within the container lid.
  • higher-level UN approvals also for hazardous liquid fill goods—can be acquired.
  • bunged drums of thermoplastic material have the drawback that the closed drums are subject to an internal pressure below atmospheric (vacuum formation), as the fill goods subsequently cool down, causing oftentimes lateral denting of the drum wall. This is especially critical when stacked bunged drums are involved with respect to drum drops as a result of toppling stacks.
  • the container lid is made of thermoplastic material and manufactured by injection molding process or blow molding process, and the inliner is non-detachably welded or glued in the outer peripheral region of the container lid in a gas and liquid tight manner.
  • the inliner and container lid are made of plastic, the mutual welding or welding-on of the inliner onto the edge of the container lid is preferred.
  • drum body, drum lid, and welded-on inliner are equally made of plastic material (HD-PE), wherein the drum lid with bung opening arranged laterally in the lid disk is attached by means of a tension ring of steel to the drum body.
  • This preferred design variation is—with respective UN approval—provided as replacement for normal plastic bunged drums which typically are used for the storage and transport of hazardous liquid fill goods.
  • such a packaging unit is more cost-efficient than a comparable bunged drum.
  • the container lid is made of metal and the inliner is glued in the outer peripheral region of the container lid in a gas and liquid tight manner.
  • the surface gluing with high-grade industrial adhesives constitutes hereby the optimum mode of a non-detachable connection of drum lid and inliner.
  • the lidded container according to the invention may, of course, also be used for solid, particulate, or slow-flowing, pasty fill goods, so long these goods, like liquids, can be filled with a fill pipe through the filling and emptying opening in the container lid and sucked out by means of a suction pipe out of the lidded container.
  • the container lid has a downwardly open U-shaped edge with a vertical outer and a vertical inner lid flange, and the inliner is welded on or glued on the outside onto the inner lid flange.
  • the inliner is hereby secured in a vertical fastening zone upon the drum lid.
  • the inner lid flange is hereby extended to afford a wider welding zone.
  • the inliner has on its upper end an outwardly formed edge resembling a radial flange and is welded or glued into the U-shaped lid edge in opposition to the face end of the container mouth.
  • the fastening region is hereby aligned more in horizontal direction, wherein the inliner edge reaches into the contact surface of the drum lid and is effectively clamped there additionally.
  • the inliner is normally configured as cylindrical film bag and made of thermoplastic material.
  • the liquid-tight inliner may hereby be equipped with a fabric inset for reinforcement.
  • the inliner can be thickened at its upper edge in its fastening region and can have a wall thickness of at least 1 mm.
  • the inliner can be provided with a plurality of reinforcement ribs in vertical direction.
  • FIG. 1 a perspective illustration of a lidded container according to the invention
  • FIG. 2 a cross section through the lidded container with inliner according to FIG. 1 ;
  • FIG. 3 a cross section through the container body without inliner
  • FIG. 4 a top view of the container lid
  • FIG. 5 a cutaway view, on an enlarged scale, of a cross section of the lidded container.
  • Reference numeral 10 designates in FIG. 1 a lidded container according to the invention in preferred embodiment in the shape of a solid cylindrical 220 liter lidded drum, which has a container body 12 with attached container lid 14 and tension ring closure 16 .
  • the container lid 14 has a central flat lid disk 18 formed therein with diametrically opposing bung openings and a U-shaped downwardly open lid edge 20 with an outer ring piece 22 and an inner ring piece 24 ( FIG. 5 ).
  • the central lid disk 18 is slightly elevated in relation to an outer flat, circumferential ring disk 32 .
  • Two diametrically opposing bung openings which are each closeable by a bung plug 38 in a gas and liquid tight manner, are arranged in the transition zone from outer ring disk 32 to the central lid disk 18 in bung troughs in such a recessed way that the surface of the screwed-in bung plug 38 extends in the closed state in vertical alignment with the surface of the attached tension ring 16 and the central lid disk 18 .
  • a solidly formed wrap-around bottom roll ring or foot ring 40 is arranged at the lower edge of the container body 12 for improving stability as well as attaining higher standing capability and rolling capability of the filled drum, when tilted to an inclined position.
  • the tension ring 16 spans with its upper leg the U-shaped lid edge 20 and with its lower leg a surface flange 34 , which projects substantially radially outwards and is arranged on the outer wall of the container body 12 at the top at the container opening 36 , with the tension ring pressing the container lid 14 onto the container opening 36 .
  • FIG. 2 shows a top view of the drum lid 14 .
  • Two opposing bung openings are closed in a gas and liquid tight manner with 2 inch bung plugs 38 .
  • Several stacking blocks 28 in the form of annular web pieces are provided on the outside in the flat ring disk 32 and on the inside directly behind the U-shaped lid edge. These stacking blocks 28 engage formfittingly in the engagement groove 30 arranged on the inside behind the bottom roll ring 40 (foot ring), when stacking like drums, and prevent a shift to the side of drums stacked on top of one another, e.g. when being shaken during transport.
  • FIG. 3 shows a cross sectional view of the container body or a drum body 12 with upper filling opening 36 , with upper surface flange 34 as tension ring counter support, and with bottom-side foot ring 40 . Formed directly behind the foot ring 40 is the engagement groove 30 in the flat drum bottom plate.
  • FIG. 4 shows the solid cylindrical lidded drum 10 as preferred embodiment of the invention with drum body 12 , attached drum lid 14 , and plastic inliner 26 welded onto the drum lid 14 .
  • the lidded drum has a capacity size of about 200 liters or 55 US gallons. With a height of 890 mm and an outer diameter of 585 mm, the lidded drum has almost the same dimensions as a corresponding steel drum and can be handled with the same drum gripper tools used for a steel drum.
  • the drum lid 14 is made of new plastic material (HD-PE virgin material) through an injection molding process.
  • the inliner 26 is also made of new plastic material (HD-PE) and may be manufactured by an injection molding process, deep drawing process, or from joined film material.
  • the inliner 26 may be composed as single-layered or multilayered cylindrical film bag and may have a wall thickness of 0.6 to 2 mm and a weight of about 1.2 to 3.4 kg.
  • a multilayered inliner is preferably provided with a barrier layer (permeation barrier) to prevent migration of hydrocarbons, carbon dioxide, or oxygen.
  • the gas and liquid tight inliner 26 may further be provided with a fabric inset for reinforcement and stiffening ribs extending in vertical direction to secure against twisting within the drum body, when a filled drum is slantingly rolled.
  • the drum body 12 may be manufactured by an injection molding process or blow molding process and may be made of new plastic material (HD-PE) or recycled plastic material.
  • the weight of the drum body may range from approx. 5.0 to 9.5 kg at a wall thickness of approx. 2.5 to 5 mm. Multiple use of the drum body advantageously permits a reduction in packaging costs, consumption of new material and thus material costs, and decreases the amount of waste material of used packaging containers.
  • the area “A” encircled in FIG. 4 at the top left-hand side is illustrated in FIG. 5 on an enlarged scale by way of a partial cross section. It can be seen that the inner ring piece 24 of the U-shaped lid edge 20 is prolonged such that a piece thereof extends into the container body opening 36 .
  • the smooth outer side of the annular web 24 has as fastening region 42 for welding or gluing the inliner a height of approx. 35 mm (measured on the inside from the ring disk 32 ), to which the inliner is welded or glued with the inner side of its upper rim area.
  • the inliner 26 is welded or glued with the outer side of its upper rim area to the inner side of the annular web 24 .
  • Welding or gluing is implemented along at least one circumferential continuous line.
  • two or more circumferential welding lines may be provided.
  • the lowermost and the uppermost welding lines are preferably configured linearly straight continuous, while the or one of the middle welding lines has a zigzag or wavy shape so that a wider region is used at the upper rim of the inliner for securement so that, i.a., dispersion of tensile forces is improved.
  • a broader circumferential, i.e. flat gluing zone can be realized.
  • Such a gluing zone may have a height of about 5 mm to 40 mm, preferably about 15 mm.
  • the welding zone may extend across a height of 10 mm to 50 mm, preferably about 20 mm, when at least two circumferential welding lines are welded.
  • a broader attachment zone of the inliner locally excessive tensile stress can be better dispersed across a greater surface area and absorbed so that the inliner is prevented from being overstretched and the welded connection between inliner and lid is prevented from cracking open.
  • FIG. 6 shows once more a detailed view of the container mouth and the container lid configuration.
  • the flat ring disk 32 arranged directly adjacent behind the U-shaped lid edge, is deeper by approx. 15 to 20 mm in relation to the upper end edge 32 of the U-shaped lid edge, a circumferential engagement groove is established for the use and handling of a filled lidded container by means of drum gripper tools (parrot's beak) as used also for conventional steel drums.
  • the inliner includes in the fastening zone 42 preferably a thickened edge for improving welding or gluing.
  • the wall thickness may be twice as thick there as the normal wall thickness of the inliner (about 0.5 to 2 mm).
  • the inliner may be designed in various ways.
  • the inliner 26 may be made of a metal foil or a liquid-tight plastic-coated fabric sheet through which metal threads are drawn. When used in the food industry, it may, e.g., also be provided to make the inliner 26 of a multilayered plastic film and a barrier layer against permeation (penetration) of hydrocarbons.
  • the welding or gluing in vertical direction can be combined with the inliner securement in horizontal direction in the U-shaped lid edge so that a broader fastening region and a clamping in the contact area of the U-shaped lid edge can be effected on the upper drum mouth edge in the tension zone of the tension ring closure.
  • the lidded drum according to the invention permits the complete elimination of a wrap-around sealing ring for placement in the U-shaped lid edge 20 because the container lid 14 does not have to be sealed in a gas and liquid tight manner on the upper mouth edge of the container opening, when the tension ring is closed, since the drum lid with the welded-on inliner forms already an absolutely liquid-tight unit. While conventional liquid-filled lidded drums normally become already leaky when encountering container drops from drop heights of 1.2 m, the lidded container according to the invention remains absolutely liquid-tight, even when dropped from greater heights so long as the tension ring does not completely pop off.
  • a liquid-tight lidded drum is thus created in a simple manner and has performance data almost on par with a closed single-piece bunged drum.
  • the tightness of the lidded drum according to the invention is significantly increased when subjected to container drops and internal pressure stress so that it is best suited for use of liquid fill goods and can even be approved for certain hazardous liquid fill goods.
  • the drum body which now fulfills solely a purely protective function and does not come into contact with the fill goods and thus is free from any adhering fill goods residues after discharge of the fill goods, can be used again many times in a manner that is gentle to the material and environment.
