Abstract

Abstract of the Disclosure A container for liquids includes an inner plastic container member and an outer sheet metal jacket tightly abutting the container member. The jacket has a welded-on cover and bottom and lugs for attaching the jacket to a palette. A palette supports the container member and jacket. The plastic member has sealable inlet and outlet openings. Preferably the cover and bottom are roller-welded and the metal edges and recesses of the jacket have flanged or roller beads. The lugs overlap a rolled bead at the bottom of the jacket.

Description

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.

Claims

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. A pallet-mounted container for liquids, comprising a pallet, a metal casing secured to 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 therethrough 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 container and the casing, the supporting ring being discontinuous adjacent the discharge aperture and the ends of the ring adjacent the discharge aperture being spaced a substantial distance from the discharge aperture and from the closure.

2. A container as claimed in claim 1, in which said closure is spaced inwardly from the margins of said casing aperture in a direction along the axis of the discharge aperture.

3. A container as claimed in claim 1, in which the inner surface of said support ring in contact with said container is continuously concave in cross section.

4. A container as claimed in claim 1, in which said supporting ring is foamed plastic.
