DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates a side for a container, particularly a container which is used for the transport of liquids.
BACKGROUND TO THE INVENTION
It is common to provide containers comprised of a base and four interconnectable sides adapted to be demountably secured to the base, and a lid. Such containers are provided with a liner bag to hold liquid and discharge is through a nozzle on the bag which projects through one container side adjacent the container base.
In use the sides are mounted on the base and interlocked to provide a bag enclosure and the liner bag is placed in the enclosure and the nozzle is inserted into and passed through the nozzle hole in the container side from the inside of the enclosure. An operator finds it difficult to reach down into the container to insert the bag nozzle in the nozzle hole because the container sides are in the order of 1.2M high.
PRIOR ART
In the past one means of overcoming the above problem was the have the "nozzle side" of the enclosure laterally split to provide a lower part and an upper part. The upper part was connected by hinges to the lower part to allow the upper part to pivot outwardly. A major drawback with this arrangement was the bulkiness of the hinging arrangements which were used. The hinged part of the enclosure wall was held in place in the unfolded condition by bolts connecting the folding part to the adjacent enclosure walls.
OBJECTS OF THE INVENTION
The present invention has for its principal object the elimination of the bulky external hinge means of the prior art containers. A further object is to provide load resisting means at the hinge line between the upper and lower side parts to substantially eliminate pressure loads on the hinge connecting the upper and lower parts as are exerted by the load within a container of which the proposed container side forms part.
STATEMENT OF THE INVENTION
The invention can be said to provide a container side having an upper part and a lower part hinged together so the upper part can pivot relative to the lower part from a substantially co-planar operational condition to an overlying loading condition in which a liner bag can be readily loaded into a container of which the said side is an element, each container side part includes a frame covered with a liner panel and the liner panels provide a substantially continuous planar surface for the container side when said side parts are in the operational condition, load resisting means to couple adjacent sides of the frames of the upper and lower side parts where said load resisting means is automatically engaged when said side parts approach the operational condition following hinging of said upper part from the loading condition and which automatically disengages as said upper part is hinged from the operational condition towards the loading condition.
BRIEF DESCRIPTION OF THE DRAWINGS
Presently preferred embodiments of the invention will now be described with reference to the accompanying drawings in which;
FIG. 1 is a perspective view of a first embodiment of a container nozzle side according to the invention,
FIG. 2 is a perspective view of a container incorporating the nozzle side of FIG. 1 in an inwardly hinged liner bag loading condition,
FIG. 3 is an enlarged sectional view on the section line 3--3 of FIG. 1,
FIG. 4 is an enlarged sectional view on the section line 3--3 of FIG. 1 as it would appear when hinged as shown in FIG. 2,
FIG. 5 is a view similar to FIG. 3 of a second embodiment of the invention,
FIG. 6 is a view of the FIG. 5 components with the side parts hinging to a liner bag loading condition,
FIG. 7 is view similar to FIG. 5 showing an alternate form of load resisting means, and
FIG. 8 is a view of the FIG. 7 components with the side parts hinging to a liner bag loading condition.
DETAILED DESCRIPTION OF THE DRAWINGS
A typical container which would include the nozzle side of the invention as illustrated in FIG. 2 would comprise four sides 1, 2, 3, 4 fixed permanently or demountably to the base 18
