  • a handling attachment can be provided at the [56] References Cited top of the drum to accept the top hook of a hand UNITED STATES PATENTS truck or a similar transporting device.
  • the present invention relates generally to containers 5 and, more particularly, to a blow-molded drum of the stackable type, made of atherm'oplastic material.
  • One such conventional blow-molded drum comprises, for example, a substantially cylindrical main body and a head and bottom portion which are considerably tapered inwardly, relative to the longitudinal axis of the drum, to provide the required structural strength for the container.
  • the head and bottom portions of this conventional drum terminate in generally planar end walls with depressions formed at diametrically opposite sides of the top end wall.

  • Each of the tubular projections communicates with the interior of the drum.
  • the upper bpen edges of the projections terminate in a plane corresponding to the general plane of the top wall surface.
  • reinforcing webs are provided in the respective depressions and are integrally formed with the pro era] surfaces which include a threaded portion adapted to intermesh with the threaded portion of a bung or closure cap which, normally, seals the tubular projections, isolating the interior from the environment.
  • this type of plastic drum is provided with an eyelet positioned in the central portion of the top end wall intermediate the depressions therein.
  • eyelet may be disposed in a recess beneath the general plane of the'end wall.
  • This centrally positioned eyelet accepts the hook of a crane or similar lifting device for vertical lifting or positioning of the drum during loading or unloading thereof.
  • the keg-shape of conventional plastic drums' prevents normal manual handling thereof as compared with the common steel drum which is substantially cylindrical with relatively flat top and bottom surfaces and can be easily rolled and positioned onto the platshaped configuration, which enables a standard fork truck to lift the drum.
  • Plastic drums of the type under discussion do not have such well defined edge portions due to the degree ofcurvature at the top and bottom portions, and hence, these drums are unsuitable for use with a fork-lift truck.
  • a drum of substantially cylindrical configuration has slightly curved top and bottom sections, terminating in generally planar end walls.
  • the drum is made of a high density thermoplastic material; such as polyethylene, and is blow-molded in the conventional manner.
  • a pair of indentations or recesses positioned diametrically opposite each other. Each recess provides a generally flat surface which extends substantially normal to thelon'gitudinal axis of the drum, parallel to the planar top end walls thereof.
  • the purpose of providing the circumferential wall with such flat recessed indentations is to provide bearing surfaces forthe straight and flat forks of a conventional fork-lift truck.
  • the indentations are configured to support the entire weight of a fully filled drum and do not affect the structural strength of the drum. Also, as a result of the cylindrical circumference and flat bot tom surface of the drum, the latter, when positioned on the forks or bottom plate of a hand truck, is easily balanced against the upwardly directed supports of the hand truck, a feature'which, hitherto, was impossible due to the rounded configuration of the circumferential surface of the conventional plastic drums.
  • edge portions are formed between the circumferential wall and the top and bottom surfaces. 'Such an edge portion at the bottom region of the drum enables the latter to be easily manually rolled and, in additiomenables the drum to be adequately engaged by and positioned onto the forks or plate of a standard hand lift truck.
  • the degree of curvature at the bottom of the drum is such as to enable the rather short forks to be easily disposed beneath the drum bottom surface,a feature which, as hereinbefore discussed, was practically impossible, again as a result of the rather large curvature at the bottom portions of conventional plastic drums.
  • the handling attachment which further facilitates handling and lifting of the drum by a hand truck.
  • the handling attachment is positioned at the drum top and enables the top to be con nected to the conventional top hook with which the hand truck is usually equipped to connect the upper end of the drum to the truck.
  • the handling attachment may, of course, also be used to accept the hook or connecting member ofa similar lifting device which utilizes the hook or connecting member for stabilizing the drum on the device.
  • the handling attachment in one embodiment thereof, is in the form of a flexible loop attached laterally to the bung projection at the top wall of the drum.
  • the loop is arranged to accept the top hook of the hand truck.
  • the handling attachment is formed by a wall receptacle which extends slightly angularly inwardly from the planar Surface at the top wall of the drum, adjacent the peripheral edge thereof, and defines a cutout portion between the drum side and bung projection. With the drum positioned on the forks of the hand truck, the cutout portion accepts the top hook of the hand truck.

  • FIGS. 8a and 8b are fragmentary views showing profiles of other embodiments oflifting portions of a drum.
  • FIG. 1 there is shown a blow-molded drum 10 which is made of a thermoplastic material such as a heavy density polyethylene.
  • the drum is of substantially cylindrical configuration and, as shown, has a generally straight periphery 12 and slightly curved top and bottom portions 14, 16, respectively,
  • top portion 14 Provided in the circumferential wall of the top portion 14, adjacent the top end wall 18, are two recesses or indentations 22, 24 positioned diametrically opposite each other in the top portion 14.
  • the recesses 22, 24 initially define curved shoulder sections 26, 28, which deflect rather sharply from the generally straight line P of the projected periphery l2, inwardly relative to the longitudinal axis A of the drum 10.
  • the curved sections 26, 28 merge into substantially straight upright sections 30, 32, which extend upwards in general alignment with the longitudinal axis A of the drum l0 and extend lengthwise to form longitudinal channels in the side walls of the drum through which the forks ofa fork lift can be run in for the purpose of lifting the drum.
  • the sections 30, 32 terminate in overhanging brows or lips having planar surfaces 34, 36, which extend in a normal plane relative to the axis A of the drum 10.
  • the straight surfaces 34, 36 When the straight surfaces 34, 36 are engaged and lifted by the forks of, for example, a standard fork-lift truck, they provide bearing surfaces for the forks and effect equal and uniform weight distribution of a filled drum.
  • the fork insertion recesses 22 and 24 are provided on the top portion 14 of the drum. This location for the recesses gives greatest stability and avoidance of tipping in the lifting ofa fully loaded drum, because the center of gravity of the fully loaded drum then lies well below the supporting forks. It should be understood that, if desired, additional recesses may be provided in the top portion, to permit fork lift approach from different angles, and also that the recesses may be positioned in other drum portions. Thus, for example, the drum may be provided in its middle portion with diametrically opposed recesses similar to 22 and 24.
  • the drum be as readily liftable by a fork lift when the drum is upside down, and in such event the bottom portion of the drum may be provided with an oppositely disposed pair of recesses, having a configuration as shown in FIG. 8a, or a more central portion of the drum may be provided with pair of recesses having a configuration with both top and bottom lifting brows as shown in FIG. 8b.
  • planar surfaces of the recesses in the respective wall sections are dimensioned as later discussed so as to prevent their dislodgement from the forks.
  • top and bottom portions l4, 16 have a curvature with a deflection of only a few degrees relative to the straight sides 12 of the drum. This slight degree of curvature is sufficient to give great structural strength to the container at the top and bottom sections.
  • a drum thus configured is, for example, a substantial increase in dimension of the bot tom surface as compared with bottom portions of drums with a considerably high degree of curvature such as, for example, a kegor egg-shaped drum.
  • the bottom surface of the present drum permits positive engagement with and support by the forks or platform of a standard hand truck, which would not be feasible with a drum with a rather strongly curved bottom section. Since the forks or platform of the hand truck are relatively short in length, generally they would not extend far enough to reach and adequately support the bottom surface of such drums.
  • the slight degree of curvature at the bottom section 16 provides a larger bearing surface of the bottom wall per se and, consequently, provides a greater support surface; e.g., for the platform of a truck.
  • the top end wall 18 is provided with bung projections 38, 40 of conventional design.
  • the projections are positioned in depressions 42, 44, which are disposed diametrically opposite each other in the top end wall 18.
  • the projections 38, 40 define openings therein which communicate the interior of the drum with the atmosphere, the openings or bung holes being arranged to receive the usual bungs or stoppers.
  • the upper edges of the projections 38, 40, as shown, are located in the general plane of the top wall 18 while the upper edges of the bungs, not shown, are positioned in the plane of the upper limits of the projections.
  • This arrangement provides that the overall upper wall 18 is generally flat which, as will be appreciated, provides increased stability in the stacking of the drums on top of each other.
  • Reinforcing webs 46 are provided at the sides of the projections 38, 40, extending inwardly towards the center of the drum. Located below or extending through the web 46, as shown, is a cutout or eyelet 48.
  • the eyelet 48 forms an opening for the pas sage of a loop-shaped, flexible member 50 which loosely surrounds the bung projection 38.
  • the flexible member 50 e.g., a flexible wire cable, constitutes a handling attachment for the drum in that it is arranged to receive, for example, the upper connecting hook of a standard hand truck, or the hook ofa similar handling device.
  • FIG. 2 One such arrangement is illustrated in FIG. 2 with the hook shown in dashed lines.
  • FIGS. 4, 5 and 6 illustrate an alternative embodiment of the handling attachment of the invention.
  • the bandling attachment in this instance, is in the form of a fixed receptacle 52, open at its upper end.
  • a downwardly directed, elongated cavity 54 is arranged to receive the top hook ofa hand truck or the hook ofa similar handling device.
  • the receptacle 52 is positioned laterally in the region of the circumferential edge 56 of the top end wall 18 and is disposed so that the walls of the cavity 54 extend at a slightly outwardly inclined orientation relative to the longitudinal axis A of the drum 10.
  • the upper edges 58, 60, bounding the cavity 54, extend in a plane parallel with the general plane of the top wall 18.
  • the receptacle 52 in essence, is formed by a substantially wedge-shaped fold portion 62, including a bottom portion 64 and an outer wall portion 66.
  • the fold portion 62 is integrally formed with a substantially rectangular base portion 68, including a bung assembly 70.
  • the bung assembly 70 as shown in FIG. 6, includes an upper tubular portion 72 and the base portion 68 integrally formed therewith.

As shown, the outer side 76 of base portion 68 extends parallel with the outer wall portion 66 and angularly inwardly relative to the axis A of the drum.
  • the bung assembly 70 constructed as discussed hereinbefore is a prefabricated unit formed, e.g., by an injection molding process. To position the assembly 70 in the top end wall 18 of the drum, the assembly is initially appropriately placed in the matrix used for shaping the drum and the latter is subsequently formed around the assembly 70 by a blow-molding process. It should be noted that the assembly 70 is preferably of a plastic substance with a higher melting point than that used for manufacturing the drum in order to avoid deformation or melting of the prefabricated assembly 70, or parts thereof.
  • the drum is formed with an elongated, generally rectangular opening 82 provided in the top wall 18 and in which the bung assembly is appropriately located. Bounding the opening 82 is a generally rectangular wall 84, constituted by wall sections 86, 88, and a lateral wall section 92 which merges into the side wall 14 of the drum.
  • the outer circumferential surface of the base portion 68 and the fold portion 62 are provided with an integral circumferential rib portion 98, and as a result of blowmolding the drum around the assembly 70, the circumferential surface of the drum wall 84 is formed with a corresponding peripheral portion and these two portions, i.e., the rib portion 98 and the portion 100 of the drum wall 84, are in interlocking engagement with each other, as shown in FIG. 6. Also, following blowmolding the drum, the vertex 102 of fold portion 62 is in abutting engagement with an abutment surface 94 of an abutment portion 96 formed at the transistion region at the lower end of wall section 92 and the side wall 14 of the drum. Such abutment provides a reinforcing effect for the fold portion 62 and the wall section 92 in the region of the abutment portion 96.
  • a reinforcing web 106 Unitary with the drum top wall section 86 of the wall 84 and the central portion 104 of the drum top surface 18 is a reinforcing web 106 provided to add to the rigidity of the bung assembly 70 and to prevent deformation thereof.
  • the bung assembly 70 is provided with an inner annular circumferential wall 108 which at its lower end is provided with a threaded portion 110 which intermeshes with a correspondingly threaded portion 112 of a common bung 1 14, positioned in the assembly 70.
  • a threaded portion 110 Directly above the threaded portion 110 is an inwardly tapering portion 116 which tightly abuts a seal 118 provided on an inner tapering surface portion 120 of the bung.
  • This arrangement provides a positive seal of the interior of the drum.
  • a seal cap 122 is provided on the assembly 70 to prevent the bung 114 from being removed accidentally or surreptitiously.
  • the cavity 54 has a width which is substantially equal to the diameter of the tubular portion 72 of the bung assembly 70, the width being dimensioned such as to provide adequate access for the top hook of a standard hand truck.

  • the longitudinal width of the brow, corresponding to the length of chord C, subtends a central angle of approximately 62 at A.
  • the depth of the overhanging brow is at least /2 inch and preferably approximately /4 inch to 1 /2 inches to pro vide adequate support for the forks of a fork lift and allowance for the variations in fork spacing, so as to assure that the lifting brow will not fail and that the forks will not slip off.
