Easy Pour Container For Dangerous Liquids

Most 20-liter drums used in Australia are from “one-time-use” disposable steel for most common solvent applications, are generic in shape and dimensions and only permit 16 drums per layer on a standard-sized (45.6 x 45.6 in. Australian pallet). This new redesigned barrier structured 20-litres jug for Chlorpyrifos 500 insecticide from A & C Packers Pty Ltd. of Australia, with built-in handles on two sides and a tamper-evident, mechanical closure is 30-percent more efficient for transport and storage. Usually full containers are shipped two-layers-high on a pallet which represents 640 litres of product for the steel drums, in contrast to the new jug shape which allows twenty jugs per layer, two high, adding up to 800 litres in the same space.

The new jug also is reusable with a 5-year life cycle and recyclable as the resin from the recycled containers can be used to make drainage pipes.

Plastic drums or jugs used in Australia generally are made of HDPE. The material accommodates water-based products well, but may not be compatible with agricultural products such as fungicides and pesticides that are solvent-based. In these circumstances, containers might have to be fluorinated with the only Australian fluorinator located in Sydney. Fluorination is a chemical reaction that introduces fluorine into a compound. It prevents container panelling and distortion and reduces chemical permeation, weight loss, odour emission and flavour or fragrance loss. (for more details see my Packaging Dictionary). The extra fluorination process is very expensive.

To bypass the additional fluorination step, A&C Packers developed a proprietary six-layer extrusion/blow-moulded HDPE container with the necessary barrier made of DuPont’s Selar polyamide, an amorphous nylon resin that needs no fluorination.

Besides the special barrier construction, the container also offers a new 63-mm, Easy Pour “glug-free”, tamper-evident, wedge-seal neck design from Dorony Pty Ltd. An elegant solution to the glugging problem relying on the container design along with the position of the neck and which helps to avoid spills or splashing when pouring. By changing the pouring direction, a bubble cannot be trapped inside the container. When used correctly, the design allows a controlled pour from start to finish, without glugging, in around a third less time to empty the container than a conventional drum, according to the manufacturer.

It also allows the container to be drained to the very last drop by turning the drum back around and draining it in the conventional pouring direction.

The container has received UN certification for dangerous goods
