Metal coated with a polymer film having a thickness between 10 and 500 .mu.m. The film is a terpolymer comprising 88 to 98.7 mole % of units derived from ethylene, from 1 to 10 mol % of units derived from an alkyl (meth)-acrylate, and from 0.3 to 3 mol % of units derived from maleic anhydride, and optionally may contain up to 5 mol % of units derived from a fourth monomer selected from .alpha.-olefins having from 3 to 8 carbon atoms, monoalkyl maleates and dialkyl maleates in which the alkyl groups have from 1 to 6 carbon atoms, vinyl acetate, and carbon monoxide. The terpolymer film has a melt index of between 2 and 10 dg/minute. The metal substrate is coated with the terpolymer film at a temperature between 140.degree. C. and 300.degree. C., the speed of travel of the metal substrate being between 40 to 400 meters per minute.

A storage/transport container has a rigid and floor-forming pallet having a generally rectangular outer edge having four sides, an annular and erect outer wall in the form of a gridwork of metal rods defining a plurality of generally flat side panels extending upward from the sides of the edges, meeting at corners, and each formed of a set of horizontal metal rods and a set of vertical metal rods, and an inner vessel composed of flexible plastic material enclosed by the outer wall and supported on the pallet. The gridworks are attached to the pallet generally at the respective sides thereof. The rods of one of the sets of each side panel are each formed with at least two straight outer portions lying generally in a respective vertical plane extending upwardly from the respective side and joining the respective corners and at least two straight angled portions extending at an acute angle to the respective vertical plane and each having an outer end connected at the respective plane to one of the respective outer portions and an inner end connected inward of the respective plane to one of the inner ends of one of the angled portions of the respective rod. Thus the straight and angled portions together form at least one inset on each side panel.

摘要:
Modified copolymers which have viscosities which vary very markedly with changes in temperature are obtained by malaxating a statistical copolymer of ethylene and maleic anhydride containing between 0.5 and 20% by weight of units derived from maleic anhydride and having a melt index of between 0.1 and 500 dg/min, in the molten state with at least one chemical reagent containing at least two reactive groups which are amine or alcoholic --OH groups but at most primary or secondary amine group and at least one alcoholic --OH group.
摘要:
A transport and storage container has an annular and erect outer wall constituted as a grid of welded-together vertical and horizontal bars and having a lower edge provided with a lower-edge bar and an upper edge provided with an upper-edge bar, a normally horizontal and generally rectangular sheet-metal floor plate having an inwardly open C-section outer rim engaged over the lower-edge bar, and a flexible inner vessel enclosed by the outer wall and resting on the floor plate. The floor plate has four sides including two opposite sides formed with the C-section outer rim. In addition another of the sides is also formed with the C-section rim and a fourth side is free of the C-section rim and the fourth side of the floor plate is formed with outwardly projecting tabs that engage over the lower-edge bar. This makes assembling the container a simple matter of sliding the plate parallel to its opposite sides underneath the outer wall with the rims engaging over corresponding sections of the lower-edge bar until the tabs engage over and past at least one further section of the lower-edge bar. The tabs can be bend down over the fourth side to lock the assembly permanently together.
摘要:
A transport and storage container for flowable materials has an annular and erect outer wall in the form of a gridwork of bars having a lower edge and provided at the edge with an annular stiffening bar and a pallet-like floor downwardly closing the wall, forming therewith an outer vessel, and provided with a plurality of wooden foot beams each having a ground-engaging lower surface, an upper surface, and a pair of ends. Respective steel plates on the upper surfaces of the foot beams each have bent-down ends overlying the respective beam ends. Fasteners such as screws or nails are engaged through the steel-plate ends into the respective beam ends. Integral connections are provided between each of the plates and the annular stiffening bar at the lower edge of the wall. An inner vessel composed of flexible plastic material is enclosed by the outer wall and supported on the floor.
