Definitions

  • the instant invention relates generally to indust ⁇ rial drums for holding materials therein and more particularly to a drum liner to be removably retained within the industrial drum.
  • drums are not easily disposed of and present environmental problems when emptied of their contents.
  • a primary object of the present invention is to provide a drum liner that will overcome the shortcomings of the prior art devices. Another object is to provide a drum liner which when inserted within the industrial drum and filled with material will protect the drum from the material.
  • An additional object is to provide a drum liner in which the containment bag has a low volume when the materials are removed therefrom so that the drum liner can be removed from ⁇ t e drum and economically disposed of, thereby making the drum itself reusable or disposable.
  • a further object is to provide a drum liner that is simple and easy to use.
  • a still further object is to provide a drum liner that is economical in cost to manufacture.
  • the present invention is directed to a drum liner comprised of a containment bag connected to a neck portion. A leak proof seal is formed between the neck portion and the containment bag.
  • the drum liner of one embodiment is preferably used in conjunction with a standard 55 gallon industrial drum having a threaded bunghole and an air vent.
  • the containment bag of the drum liner is rolled-up and inserted through the bunghole.
  • the drum liner is secured to the drum by mating external threads of the neck portion with the threaded bunghole.
  • the liner is then preexpanded with air to allow it to unroll and then filled with material.
  • An externally threaded bung cover is then mated with internal threads in the neck portion of the drum liner to seal the material in the drum liner.
  • a standard transfer pump may be used.
  • Thin elongated stiffeners .spaced slightly apart along the walls of the containment bag may be employed to prevent the containment bag from collapsing in on itself and impeding the flow of material out of the drum liner.
  • the neck portion of the drum liner snap-fits into the bunghole of the drum.
  • the ' drum may be of the standard type mentioned previously, or of the type having a removable cover: Removable cover industrial drums are preferred in this embodiment since they are generally made of fiberboard. The ability to practice the invention with fiberboard drums is advantageous because these drums weigh considerably less than conventional steel drums and are readily disposed of without undue cost and adverse environmental impact. An additional advantage of using removable cover drums is that the containment bag can be placed in the drum without being rolled-up. However, preexpansion with air prior to filling is still preferable.
  • FIGURES 1A through 1C are elevational views showing various steps of a preferred embodiment of the drum liner being inserted into and removed from an industrial drum.
  • FIGURE 2 is a cross sectional view of the drum liner taken along line 2-2 in Figure IB.

  • FIGS. 1 through 4 illustrate one preferred embodiment of drum liner 10 for an industrial drum 18 of the type that has an internally threaded bunghole 22, an externally threaded bung cover 34 and an air vent 20.
  • the liner 10 consists of a neck 12 and a containment bag 14.
  • the neck 12 has internal threads 28 and external threads 30 of the same general diameter.
  • the external threads 30 engage with the internally threaded bunghole 22 in the industrial drum 18 while the internal threads 28 engage with the externally threaded bung cover 34.
  • the containment bag 14 is for holding material 38 therein and away from the internal walls of the drum 18.
  • the bag 14 has a mouth 15 that connects with the neck 12 to form a leak proof seal 32 therebetween.
  • a plurality of thin elongated stiffeners 36 may be added to keep the containment bag in a generally vertical extended position when collapsed and to prevent the containment bag 14, when full of material 38, from compressing onto itself when the industrial drum 18 is tipped over on ground line 40. If employed, the stiffeners 36 are spaced apart and vertically placed within wall 17 of the containment bag 14.
  • a set screw 16 may be threaded transversely through the neck 12 to hold a pipe 24 of a transfer pump 26 stationary and elevated (at distance "A" in Ficrure IB) from the bottom 19 of the containment bag 14. This permits the transfer pump 26 to remove all of material 38 therefrom so that the liner 10 can be removed from the industrial drum 18 and properly disposed of.
  • the neck 12 may be fabricated out of rigid or semi-rigid inert materials, such as polyethylene.
  • the containment bag 14 may be made from any inert, non-corrosive flexible material (e.g. polyethylene or alu inized polyethylene) . If stiffeners are desired they may also be made from a rigid or semi-rigid inert material (e.g. polyethylene) .
  • the drum liner 10 of this preferred embodiment is used as follows:
  • Step 1 Figure 1 shows the liner 10 before it is installed within the drum 18.
  • Step 2 Figure 1A shows the liner 10 installed within the drum 18 with containment bag 14 rolled-up and the neck 12 threaded into the bunghole 22 with bung cover 34 threaded into neck 17.
  • Step 3 Figure IB shows the containment bag 14 full of material 38 ready to be removed therefrom by the transfer pump 26.
  • Step 4 Figure 1C shows the liner 10 removed from the industrial drum 18 after material 38 has been completely emptied therefrom.
  • FIGS 5 through 7 illustrate another preferred embodiment of drum liner 110 for a drum of the type having a removable cover 102.
  • the removable cover 102 has a bun ⁇ access hole 122 and an air vent 120.
  • the removable cover 102 preferably is held in place by a rim clamp 104.
  • the drum liner 110 of the embodiment of Figs. 5-7 consists of a neck 112 and a containment bag 114.
  • the neck 112 has internal threads 128 that mate with an externally threaded bung cover 134.
  • the neck 112 snap-fits securely into the bung access hole 132 thus supporting containment bag 114.
  • the material 138 is held away from contact with the internal walls of drum 118 by containment bag 114.
  • the containment bag 114 is connected to the neck 112 (preferably by heat sealing) to form a leak proof seal therebetween.
  • stiffeners may be employed with this embodiment. However, if a . sufficiently thick containment bag 114 is used, stiffeners are not generally required.
  • the containment bag 114 and neck 112 may be made of the same materials detailed above for the previous embodiment (Figs. 1-4) . However, this configuration permits the use of a fiberboard drum with a weight approximately one-half that of a standard metal industrial drum. Additionally, these drums are more easily disposed of and provide for greater handling ease.
  • a conventional transfer pump will fit through the neck 112 and may be employed to remove the material 138.
  • the entire drum 118 may simply be tipped on its side and the material 138 allowed to flow out by gravitational force. Once the material 138 has been removed., the liner 110 may be easil y discarded. The drum 118 may be re-used or discarded without adverse environmental impact.
  • the drum liner 110 of this preferred embodiment is used by:
  • FIGS 8 through 12 illustrate a third .preferred embodiment of drum liner 210 for an industrial. drum 212 of the type having an off-center bunghole 214, a bung cover 216 having internal threads 218, and an air vent 220.
  • a collar 222 is provided with external threads 224 on its top portion and an internal annular lip 226 on its bottom portion. The collar 222 is inserted into 'the bunghole 214 of the industrial drum 212 such that the top portion extends out from the bunghole.
  • the bung cover 216 can be threaded onto the collar 222 to secure the flange 230 of the neck 228 between the bung cover 216 and the lip 226.
  • An overside containment bag 232 for holding material therein and away from the industrial drum 212 has a mouth 234 that connects, off-center, with the bottom of the neck 228 to form a leak-proof seal therebetween.
  • a structure 236 for properly positioning the containment bag 232 within the industrial drum 212 before filling is also provided.
  • the aligning structure 236 includes a key 238 formed within the collar 222 that mates with a keyway 240 formed in the flange 230.
  • the containment bag 232 is in the proper position to compensate for the bunghole 214 being off-center. This permits the containment bag 232 to fill evenly within the industrial drum 212.
  • the liner 210 may further contain a plurality of thin elongated stiffeners 242 spaced apart and vertically places within wall of the containment bag 232.
  • the stiffeners are designed to keep the containment bag in a generally vertically extended position when collapsed and to prevent the containment bag 32, when full of the material, from compressing onto itself when the industrial drum 212 is tipped over.
