Abstract: A pallet container includes a bottle, an enclosure for the bottle as well as a plastic pallet. The enclosure is a grid connected to a plastic pallet by having a lower horizontal circumferential rod received in a laterally opening circumferential groove in the plastic pallet. The rod can be locked through the use of a side plate.

Abstract: A negative pressure dispense system comprises a dispense assembly to be fitted to a drum or other fluid container, and a coupling head to mate with the dispense assembly. The dispense assembly has an air valve to control the ingress of air to the fluid container and a fluid valve to control the egress of fluid from the fluid container. The coupling head seals solely with and opens the fluid valve. The dispense assembly and coupling head have complementary mating features that inter-engage upon relative mating movement between the dispense assembly and the coupling head. The dispense assembly fluid valve has a rotatable valve member, the coupling head has a part shaped to engage the rotatable valve member, and the dispense assembly and coupling head mating features inter-engage upon relative rotation whereby, in use, as the coupling head is rotated in the dispense assembly the mating features engage and the coupling head part engages and rotates the rotatable valve member to open the fluid valve.

Abstract: Disclosed herein is a method of and apparatus for negative pressure dispensing of fluids wherein a dispense valve assembly (12) seals a container (18) and has valves (26) for ingress of ambient air and (38) for egress of dispensed fluid respectively, and a coupling head (58) mates with the dispense valve assembly and has a mechanism (62, 74, 84) operative to open the air and fluid valves and form a sealed connection (52, 84) solely with the fluid valve, such that fluid can be pumped out of the container via the fluid valve and the coupling head, whilst ambient air flows into the container via the air valve.

Abstract: A method of securing a two piece plastic nozzle and overlying screw cap closure assembly to a plastic pail cover wherein the nozzle has a cylindrical body portion which is inserted into a cover opening to form a friction fit therewith. The overlying screw cap is then rigidly supported as a sonic welding horn is brought into axial engagement with the protruding nozzle body portion. Energization of the sonic welding horn causes the nozzle body portion to soften and deform radially outwardly into a circumferentially enlarged rivet connection. Continued axial displacement of the sonic welding horn creates a plastic bond about the periphery of the rivet connection so as to close off any leakage path therearound. At the same time any radial dispersion of plastic material resulting from the bonding process is locally contained about the rivet connection periphery.
