This invention relates to plastic palette-supported containers for
liquids which are provided with a sealable inflow and outflow opening each.
Known palette-supported containers of this kind are conventionally
enclosed in wooden planking which fails to meet all requirements and does not
permit stacking.
It is an object of the present invention to provide a sturdy
palette-supported container which may be used as a one-way, or discardable
container and which can be stacked up to three containers in height.
Accordingly the pallet-mounted container for ]iquids of the
invention comprises a pallet, a metal casing secured on the pallet, a thin-
walled plastic container supported by the pallet and housed within the casing
with the wall of the container lying adjacent to the casing, a discharge
aperture located adjacent the bottom of the container, a removable closure
closing said discharge aperture, the metal casing having an aperture there-
through of a diameter substantially greater than that of the closure and
surrounding the closure with substantial clearance, and a supporting ring
disposed in and extending around the bottom corner of the inside of the
casing between the contai~er and the casing, the supporting ring being dis-
continuous adjacent the discharge aperture and the ends of the ring ad~acent
the discharge aperture being spaced a su~stantial distance from the discharge
aperture and from the closure.
The casing or jacket is advisably made ~rom galvaniæed sheet steel
and includes a cover and bottom which are roller welded.
Moreover, there may be a ring of polystyrol foam provided between ~-
the plastic container and the sheet metal jacket.
Further preferred features are to be seen in that an inlet opening
is disposed ln the centre of an indentation extending across the width of the
upper wall of the plastic container and in that in the longitudinal centre of
the upper wall, or of the indentation therein, suspending loops are formed on
at both edges of that indentatlon.
A pre~erred embodiment of the present invention is described in
detail with the aid of the accompanying drawinge wherein:
Figure 1 is a lateral elevation of a palette-supported container
according to the present invention;
Figure 2 is a plan view;
Pigure 3 is a view according to Figure 1~ taken from the left;
Figure 4 is an enlargement of section IV indicated in Figure 3.
A plastic container 1 of rectangular cross-section, made froDI poly-
~thylene and ha~in~ rounded-off edges, is enclosed in a tight-fitting fashion
by a sheet metal jacke~ 2 made rom galvanized sheet s~eel which permits not
only Q ~riple stacking, bu~ simultaneously forms a suppsrting structure for
tbe plastic con$ainer 1. Thc sheet mekal jacket is provided with a cover 3
and a bottom 4 which are affixed by means of roller welding.
The plastic container 1 is provided in the centre of its upper wall
with an inlet opening 5 which is adapted *o be sealed by msans of a threaded
lid 6, as illustrated, or by means of a plastic cam lid. The plastic container
1 is provided Wit}l an outlet opening 7 which is likewise adapted to be sealed
by means of a threaded lid 8 and additionally by means of a plastic coated ~oil
(not illustrated). In ~he areas of the inlet and outlet openings 5, 7 the
cover 3 and the sheet metal jacket 2 are provided with corresponding indenta-
tions or openings 9, lO, where the metal edges are flanged, in order to pre-
vent any sharp edges.
The uni~ formed by means of plas~ic container 1 and sheet metal
jacket 2 is adap~ed ~o be attached to a palette 13 by means of nails or screws
14 driven in~o fou~ lugs 12 which overlap a flanged bead 15 in the bottom 4 of
the sheet metal jack~ 2 at the four rounded-off corners. The cover 3 is like-
wise provided wi~h a flanged bead 15.
Figures 1 to 3 illustrate that the upper wall of the plastic container
1 is pro~ided with an inden~a~ion 16 across the surface of the wall. In the
centre of this indentation, the inlet opening 5 is provided. In ~wo transition
areas 17 of the indenta~ion 16 there are suspending loops 18 fo~med on the con-
tainer and extending in a long1tudinal plane, perpendicular to the plastic con-
tainer l. The plastic container 1 is supported hy means of a supporting ring

19 made from polystyrol foam and dispos~d in tight-itting fashion be~ween the
lower rounded-off edges of the plastic container 1 and the sheet metal jacket,
Eyelets 20 are provided for securing the sealing of the upper and
the lower threaded lids 6, 8.
In view of ~he supporting structure formed around the container by
means of sheet metal jacket 2, the inner plastic container 1 may be produced
by a blowing method as a rather thin-walled receptacle. This results in a
reduction in price so ~ha~ the complete palette supported container, in parti-
cular on long distancesJ such as overseas, can be used as a discardable con-
tainer. For sllorter distances, the pale~te-supported container may be included
in an initial shipment, set up at the place of use and later be refilled by
tank truck, provided the same liquidsJ such as paints, for example, are used.
~ he present invention thus provides a palette-supported container
which is practical, as it can be used as a discard as well as a multiple -use
container. It can be manufactured in three sizes, in a 600, an 800 and a 1000
liter capacity. The cross-sectional dimensions ~dimensions of the palette~
remain the same in every case and the containers are distinguished from one
another merely by their height.
