Stackable re-useable container
Abstract
A reusable container, made of a thermoplastic material, with at
least one filler and drain opening (18) in the top panel (20) and
with a circumferential upper and lower stacking ring (12, 16). To
permit reuse, direct stackability, good residual drainability as
well as good manipulability of the container, this invention
provides for the upper stacking ring (12) to have a slightly larger
diameter than the lower stacking ring (16) and to feature on the
inside of its upper rim a recess matching the diameter of the lower
stacking ring (16) and on the outside a vertically protruding
circular flange, so that, when stacked one container atop the
other, the lower stacking ring of the upper container fits into the
recess in the upper stacking ring of the barrel underneath and is
snugly centered therein by the vertically protruding circular
flange. This allows for the direct, multiple, secure stacking of
the containers that are the object of this invention.

Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. application Ser.
No. 09/555,011, filed Sep. 13, 2000, now U.S. Pat. No. _______,
which is the U.S. National Stage designation of PCT/EP98/07554,
filed Nov. 23, 1998.
BACKGROUND OF THE INVENTION
[0002] This invention relates to a reusable container made of a
thermoplastic material, with at least one filler and drain opening
in the top panel or container lid, and with an upper and a lower
circumferential stacking ring. A similar thermoplastic container
has been described for instance in DE-A 26 29 630. That earlier
container, featuring thin extruded side walls, offers relatively
poor stackability, its residual drainability is inadequate and it
is not suitable for reuse.
SUMMARY OF THE INVENTION
[0003] It is the objective of this invention to eliminate such
shortcomings by introducing a reusable container which is sturdy in
design, permits direct multi-tiered stacking, offers good residual
drainability and, in particular, allows for multiple use and
facilitated manipulation.
[0004] According to the invention, this is accomplished by means of
the characteristic features specified in patent claim 1. By giving
the upper stacking ring a slightly larger diameter than the lower
stacking ring, providing a recess inside the top rim of the upper
stacking ring which recess matches the diameter of the lower
stacking ring, and incorporating on the outside a vertically
protruding circular flange whereby, when stacked one container atop
the other, the lower stacking ring of the upper container fits into
the recess in the upper stacking ring of the container underneath
and is snugly centered by the vertically protruding circular
flange, it is possible for containers per this invention to be
securely stacked in multiple tiers without requiring intermediate
stacking pallets. Moreover, the larger diameter of the upper
stacking ring facilitates the handling and manipulation of filled
containers of this type. Various enhanced, advantageous design
variations of this invention are specified in the subclaims.
[0005] The structural design of the container and the advantages it
offers also make the container per this invention quite suitable
for relatively hazardous liquids such as herbicides or pesticides,
allowing multiple reuse. This novel reusable container may
incorporate any of the following features and enhancements:
[0006] The upper rim at the top end of the collar of the upper
stacking ring has a solid square cross section from the outside of
which the circular flange protrudes vertically in the axial
direction;
[0007] The collar of the upper stacking ring is slightly flared
toward the outside;
[0008] The center section of the container body is fully
cylindrical over a certain axial length while its upper and lower
sections respectively connecting to the upper and lower stacking
ring are slightly rounded and tapered;
[0009] The height (=axial length) of the rounded, tapered wall
sections respectively connecting to the upper and lower stacking
ring, i.e. to the respective collar to where the fully cylindrical
section of the container wall begins, is approximately 110 mm
(4.33");
[0010] The maximum diameter of a manually manipulable i.e. portable
container with a limited capacity of not more than 70 liters (18.5
gallons) is approximately 380 mm (15") in the area of the fully
cylindrical container wall or the outer edge of the upper stacking
ring;
[0011] The top panel is essentially flat or slightly convex and is
provided in the area of its flat perimeter with two mutually
opposite, protruding bungs with gas-tight sealable bungholes;
[0012] The essentially flat or slightly convex (domed) top panel
connects via a flared or rounded circular section at the junction
of the upper stacking ring to the tapered section of the lower
container wall;
[0013] The bottom panel is slightly sloped toward one side in such
fashion that a depression (=trough) constituting a sump is formed
underneath a drain bung;
[0014] In the area of the sump, the bottom panel is provided with
at least three protrusions, slightly pointing inwards, serving to
center the bottom end of a pump tube (e.g. a Micromatic filler and
drain suction tube);
[0015] The center of the bottom panel is slightly convex or domed
to facilitate residual drainage;
[0016] The center of the top panel is slightly concave to
facilitate residual draining of an inverted container;
[0017] The container wall is a multilayered structure consisting of
at least two or more different types of thermoplastic material
(co-extrusion);
[0018] The container has a limited capacity of about 70 liters
(18.5 gallons) and is provided with at least two handles in the
upper stacking ring, so that the container is still manually
manipulable i.e. portable;
[0019] A single, interchangeable-cavity blow mold according to this
invention is capable, by inserting circular sections of different
heights in the fully cylindrical part of the container wall, of
producing containers of varying heights (same diameter, top and
bottom panels) with a capacity for instance of 25 L, 30 L, 50 L, 60
L or 70 L (6.6, 7.9, 13.2, 15.9 or 18.5 gallons);
[0020] The collar of the lower stabilizing ring above the angled
circular foot is provided with perforations (e.g. drilled holes)
allowing the circular foot of a stacked container to be fastened to
the upper stacking ring of a container underneath it, in that
suitable fastening aids (such as wire clips or plastic cable ties)
can be inserted through a perforation and a handle opening;
[0021] For fastening at least two side-by-side containers to one
another, they are so positioned that their handle openings line up,
permitting a length of a fastening aid (such as a clamping strap, a
wooden lath or board) to be inserted through the handle openings
for locking the containers together;
[0022] For more secure stacking during storage or transport,
several containers stacked on a pallet can be fastened to one
another or to the pallet itself by means of fastening aids inserted
through the handle openings in the upper stacking ring and/or
through the perforations in the circular foot;
[0023] As a particularly salient feature of the new blow mold for
producing a reusable container per this invention, the two
blow-mold parts are each provided with an attachment serving to
punch out the handle openings in the upper stacking ring. The blow
mold is designed as an interchangeable-cavity mold in which the
mold parts for the fully cylindrical center section of the
container are separated along a horizontal mold-parting plane
permitting the production of different container sizes, having the
same diameter but varying heights, by the simple process of
exchanging and inserting the desired circular section. By inserting
the desired circular center section it is thus possible to produce
in one single blow mold different container sizes with capacities
from 25 to 70 liters.

DETAILED DESCRIPTION OF THE INVENTION
[0043] FIG. 1 shows a preferred design example of a reusable
thermoplastic container 10 according to this invention, in this
case with a capacity of 50 liters (13.2 gallons) and with a
height/diameter ratio H/D of 1.60. The upper rim of the drum
incorporates as an integral part a circumferential stacking ring 12
(handling and transport ring) with two diametrically opposite
handle openings 14. The bottom rim of the container body is
equipped with a corresponding support ring 16. Built into the top
panel 20 are two mutually opposite, internally threaded 2-inch bung
fittings sealed with bungs 18.
[0044] FIG. 2 is a partly sectional side view showing an inserted
pump tube 62 (Micromatic tube) which extends all the way to the
sump 66 on the bottom panel 64 underneath the bung. As can be seen
in the illustration of the bottom panel 64 in FIG. 3, the sump area
66 is provided with four inward-protruding centering lugs 68 which
center the lower end of the pump tube 62, holding it positioned in
the sump.
[0045] FIG. 4 shows a desirable design variant of the reusable
container in the form of a small screw-lid-type barrel 22 with a
capacity of 50 liters (H/D=1.60), in which case the top panel 20 is
provided with only one large, central filler and drain opening
which is closed with a threaded cap 24. The threaded protruding
fitting may be a 2-inch or 3-inch bung fitting with an internal
thread and a matching bung with a corresponding external thread, or
the fitting has a male thread and is closed with an internal-thread
screw-on cap. The diameter may be about 80 mm (3.15") (for a K 80
screw cap) up to 400 mm (15.75") for large screw lids. Particular
preference is given to the popular sizes with a diameter of 150 mm
(5.9"), 220 mm (8.65") or 250 mm (9.85").
[0046] FIG. 5 illustrates a 60 liter screw-lid-type container
(approx. diameter 380 mm (15"), approx. height 685 mm (27"), H/D
ratio 1.75) with an interpositioned circular adapter section 70.
The reusable container may be produced from a transparent
thermoplastic material (without the addition of any coloring) or,
if opaque, with a transparent viewing strip 72, ideally with a
fill-level scale molded into the outer container wall. Where
necessary, two outward-protruding, circumferential rolling profiles
may be provided in the transitional part between the cylindrical
wall and the rounded, tapered wall sections.
[0047] FIG. 6 depicts a small 25 liter reusable container with an
H/D ratio of 0.97.
[0048] FIG. 7 is a top view of a screw-lid barrel 22 with one
central filler and drain opening for the large screw lid 24, while
the upper stacking ring 12 is perforated in the area of the
right-hand handle opening, as shown in the partial sectional
illustration.
[0049] FIG. 8 is a similar top view of a special design variant of
the reusable container per this invention in the form of a canister
26 with an L-shaped upper stacking ring 12. The basic shape of this
canister version 26 (L-ring jerrican) is essentially rectangular
and the handle openings 14 are located opposite each other in the
upper stacking ring 12 on the two long side walls while the filler
and drain opening, closed off with the screw cap 28, is positioned
at the outer perimeter of the top panel 20 next to one of the two
short side walls in between. In this case, in contrast to the lower
stacking ring, the upper stacking ring 12 is not completely
continuous but is interrupted by a cutout 30 in front of the filler
and drain opening to permit unimpeded pouring of the liquid
content. Where a large filler and drain opening is located in the
center, the upper stacking ring as well will be circumferentially
continuous.
[0050] FIG. 9 is a partial, sectional view of the corner areas of
two containers one stacked atop the other. In this case, the upper
container, with the horizontal contact surface 50 of the support
ring 16 of the circular foot 48, facing downward, rests on the
horizontal, upward-pointing contact surface 36 of the angled rim 32
of the upper stacking ring of the lower container. The circular
flange 38 (centering ring) protruding vertically from the outside
of the angled rim 32 centers the circular foot 48 of the stacked
barrel, preventing any lateral slippage of the barrels or drums for
instance due to vibration during transport. When the containers are
stacked directly one atop the other, there is no axial load on the
vertically protruding flange 38 (no leverage).
[0051] Below the junction 42 of the collar 44 of the upper stacking
ring, and again above the junction of the collar 46 of the lower
support ring 16, the container wall 40 recedes at a slightly
oblique angle or is rounded over a height from about 100 mm (4") to
the cylindrical section of the drum body. The largest angle of
inclination in this case is about 15 to 20. At the same time, the
collar 44 of the upper stacking ring 12 (angle of inclination about
5 to 8) and the collar 46 of the lower stabilizing ring 16 are
slightly sloped toward the outside. For increased radial rigidity,
the upper edge, i.e. the angled rim 32 of the upper stacking ring
is relatively thick and solid. The bottom surface of the angled rim
32 of the upper stacking ring 12 constitutes a wide, essentially
horizontal or perhaps slightly sloped contact surface 34 for the
lower claw of a barrel loader. The upper claw of the barrel loader
engages on the inside of the angled rim 32 which, being an
extension of the collar 44, serves as a counter-support.
[0052] The partial view in FIG. 10 shows a handle opening 14 in the
stacking ring 12. According to the invention, the containers are
preferably produced in one piece by a single-operation blow-molding
process employing two header dies for shaping the two
circumferential stacking rings while at the same time, still in the
blow mold, two rotary punch dies punch out the handle openings in
the upper stacking ring.
[0053] FIG. 11 illustrates one possible way to secure the
containers per this invention for transport purposes. The collar of
the lower stabilizing ring, above the circular foot 48, is provided
with several evenly spaced perforations 52. These may be for
instance simple drill holes but may also be horizontal slots
already molded in when the circular foot 48 is formed by heading
during the blow-molding process. It is thus possible to run for
instance a retaining wire or, as shown here, cable ties 54 through
the perforations 52 and the handle opening 14, securely tying the
two vertically stacked containers together. The containers are
released by simply cutting the cable ties.
[0054] FIG. 12 shows another possible way to secure the containers
per this invention for transport purposes, whereby the handle
openings are lined up and a wooden lath 56 is inserted to lock the
containers together.
[0055] FIG. 13 is a top view illustrating this fastening method
applied to containers placed side by side on a base pallet 58.
[0056] FIG. 14 depicts triple-tier direct stacking (i.e. without
intermediate pallets) of 3.times.3.times.3=27 containers 10 stacked
on a base pallet 58, in which case the containers are secured
especially against vibration during transport for instance by
clamping straps 60 run vertically through the handle openings in
the upper stacking ring down to below the deck of the pallet and,
respectively, wrapped horizontally around the containers and
attached to the pallet 58 proper.
[0057] When loading 60 liter containers per this invention (approx.
diameter 380 mm [25"], approx. height 665 mm [26.18"]) into a
20-foot ISO container (DIN 668) accommodating 10 side-by-side ISO
pallets (1140.times.1140 mm [45".times.45"]), it is possible to
load 9 containers in one plane of each ISO pallet which equals 27
containers when triple-stacked or 270 containers on 10 pallets,
with a combined capacity of 16,200 liters (4,280 gallons).
[0058] Reusable containers according to this invention may have a
container body with circular stacking and support rings yet with an
essentially rectangular, square or hexagonal base.
[0059] FIG. 15 and FIG. 16 respectively show a square-base
container 74 and a hexagonal-base container 76. The rounded comers
may also have a larger radius or curvature.
[0060] An extra-high container 78 with a capacity of about 70
liters (18.5 gallons) is depicted in FIG. 17. On one side of its
top panel, this tall container 78 is provided with a filler and
drain bung fitting 80 (diameter 80 mm [3.15"]) with an external
thread for a K 80 screw cap. It is equally possible to position the
fitting 80 in the center of the top panel.
[0061] FIG. 18 shows a section of a special design version of a
lidded container 82 according to this invention. In this case the
detachable lid 84 is provided with a stacking ring 12 (and handle
opening 14) and at least one lateral bung fitting 86. Underneath
the stacking ring 12 the lid 84 has an inverted-U-shaped peripheral
lid flange 88 with an inlaid gasket or foamed-in circular seal 90.
The lid flange 88 rests on the lip of a wall flange 92 on the rim
of the upper perimeter of the drum body. When closed, the lid
flange 88 and the wall flange 92 are locked together in gas-tight
and impermeable fashion by a clamping ring 94. This lidded drum 82
is particularly suitable for multiple reuse for holding viscous or
granular substances.
[0062] For multiple reuse, appropriately sturdy containers can be
produced in larger sizes as required, for instance with a capacity
of 100, 120, 150, 200 or 220 liters (26.4, 31.7, 39.6, 52.8 or 58.1
gallons). However, when filled, these containers can no longer be
handled manually but must be manipulated preferably with the aid of
mobile elevating platforms or forklifts with the necessary
drum-loading equipment (`parrot beak`). The features described may
