Abstract
Abstract A method of improving industrial production comprising the steps of arranging a plurality of full containers in a transporter, the container being arranged in a predetermined number of stacks of containers, each stack containing a predetermined number of containers, transporting the containers in said configuration to a destination, unloading the containers from the transporter and thereafter introducing the same, or substantially the same, number of containers into the transporter as were transported thereby to said destination but said containers being arranged in a plurality of columns of nested containers, the number of columns being less than said predetermined number of stacks and the space not occupied by the columns of steel containers being utilized to transport other articles to a further destination. Each container comprises a load receiving body, adapted to nest in the body of a similar container, and retractable leg means movable between an operative position, in which the weight of the body is supportable on the legs and a similar container can be stacked above the said container with the weight of said similar container being transmitted to the legs of said one container, and an inoperative position in which the bodies are permitted to nest.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
231 words
A container comprising a load receiving body having a length of at least 3 meters and comprising an open topped box having a base wall and downwardly and inwardly inclined sidewalls whereby the body of a similar container can be nested therein, the body having retractable leg means comprising a plurality of fixed leg parts provided externally of the body at the upper end of the body, a movable leg pivotally connected at the upper end thereof to each fixed leg part adjacent the upper end of the body for movement between an operative position, in which the movable legs extend downwardly and the lower ends thereof project below the base wall of the body and are adapted to support the weight of the body and to engage said fixed leg parts of a similar container there below upon which said one container is thereby stacked, to transmit said weight thereto, and an inoperative position in which said movable legs extend generally parallel to the top of the container and in which the bodies can be nested, leg locking means being provided rigidly to hold each movable leg in said operative position, first locking means to permit the container to be locked to a similar container when in nested relationship therewith and second locking means to permit the container to be locked to a similar container when in stacked relation therewith.
Claim 2
Dependent Claim
231 words
A container comprising a load receiving body having a length of at least 3 meters and comprising an open topped box having a base wall and downwardly and inwardly inclined sidewalls whereby the body of a similar container can be nested therein, the body having retractable leg means comprising a plurality of fixed leg parts provided externally of the body at the upper end of the body, a movable leg pivotally connected at the upper end thereof to each fixed leg part adjacent the upper end of the body for movement between an operative position, in which the movable legs extend downwardly and the lower ends thereof project below the base wall of the body and are adapted to support the weight of the body and to engage said fixed leg parts of a similar container there below upon which said one container is thereby stacked, to transmit said weight thereto, and an inoperative position in which said movable legs extend generally parallel to the top of the container and in which the bodies can be nested, leg locking means being provided rigidly to hold each movable leg in said operative position, first locking means to permit the container to be locked to a similar container when in nested relationship therewith and second locking means to permit the container to be locked to a similar container when in stacked relation therewith.
Claim 3
Dependent Claim
21 words
The invention claimed in claim 1 wherein each leg is pivotally connected to the body for movement about a horizontal axis.
Claim 4
Dependent Claim
33 words
The invention claimed in claim 2 wherein the body is rectangular in plan view and each leg lies parallel to a longer side of the body when it is in its inoperative position.
Claim 5
Dependent Claim
54 words
The invention claimed in claim 1 wherein the locking means comprises an arm pivotally mounted on the body for movement about a vertical axis between an operative position wherein an end of the arm is in locking engagement with the leg and an inoperative position wherein the arm permits pivotal movement of the leg.
Claim 6
Dependent Claim
83 words
The invention claimed in claim 1 wherein the locking means comprises a locking member mounted on the body for pivotal and sliding movement about a horizontal axis parallel to a side wall of the body, said locking member and leg having spigot and socket means which can be engaged to lock the leg in its operative position by sliding the locking member axially towards the leg from an inoperative position and then pivoting the locking member to engage the spigot and socket connection.
Claim 7
Dependent Claim
26 words
The invention claimed in claim 5 wherein securing means are provided for securing the locking member in at least one of its operative and inoperative positions.
Claim 8
Dependent Claim
19 words
The invention claimed in claim 1 wherein retaining means are provided to hold each leg in its inoperative position.
Claim 9
Dependent Claim
38 words
The invention claimed in claim 7 wherein the retaining means comprises a shoot bolted connection between a lower part of a leg and a part of the body adjacent thereto when the leg is in its inoperative position.
Claim 10
Dependent Claim
17 words
A container as claimed in claim 1 wherein said first and second locking means comprise twist locks.
Claim 11
Dependent Claim
33 words
The invention claimed in claim 1 wherein at least one side wall is hinged about a horizontal axis to permit access to be gained to the interior of the container from said side.
Claim 12
Dependent Claim
53 words
The invention claimed in claim 1 wherein at least one side wall of the container is of ribbed configuration and the ribs being tapered longitudinally and transversely whereby the corresponding ribs of another container can be arranged in nested relationship with said ribs when said other container is nested within said one container.
