摘要:
A connection assembly (5) for a grid structure suitable for use in a pallet container comprises first and second elongate elements (2, 3) connected to one another at an intersection (4). The first element (2) comprises a tube defining at least one receiving opening (6) through which the second element (3) is passed wherein the portion of the first element (2) defining the periphery of the receiving opening (6) protrudes inwards to define a collar (7) surrounding the second element (3). Typically, the inner dimension of the collar (7) is dimensioned with respect to an outer dimension of the second element (3) so as to provide a frictional fit of the two elements (2, 3). The provision of the collar (7) strengthens the intersections of the first and second element (2, 3) and enables a grid structure made from such connection assemblies (5) to withstand impacts and vibrations during use.
摘要:
A bulk liquid container including a pallet defining an annular outer peripheral portion defining an upwardly facing annular seat and a central platform portion within the outer peripheral portion; an annular cage including an annular sidewall structure and an annular lower edge positioned on the annular seat; and a bulk liquid bottle positioned in the sleeve with its sidewall structure juxtaposed to the sleeve sidewall structure and its bottom positioned on the platform portion. The pallet defines an upstanding rim extending around the annular seat and a plurality of circumferentially spaced channels opening inwardly of the annular seat and above the seat. A plurality of straps extend through openings in the rim and through an opening in the lower annular portion of the cage for passage into a respective channel. The inner end of each strap is anchored to the platform of the pallet by the downward force of the liquid in the bottle and by an interlocking structure engaging the inner end of the strap, and the outer end of the strap includes an enlarged head positioned against the outer surface of the rim. Outward force exerted by the liquid in the bottle against the sidewall of the sleeve is transferred to an outward force on the rim of the pallet, and the outward force on the rim of the pallet is in turn converted by the straps into outward pulling forces on the platform portion of the pallet so that the straps, in combination, tension the platform portion in the manner of a drum.
摘要:
A modified copolymer of ethylene and of at least one .alpha.-olefin having from 3 to 12 carbon atoms, comprising from 0.5 to 10 mole percent of units derived from the .alpha.-olefin, wherein the measured limiting viscosity of the copolymer is between 1.5 and 10 times the limiting viscosity of the copolymer calculated from the molecular weight distribution of the copolymer. Process for producing these copolymers employing at least one free-radical initiator.
