Abstract: A molded plastic pail has a pair of continuous annular flanges molded integrally on its outer wall extending radially outwardly and defining between them a free, continuous channel of constant cross-section extending around the entire circumference of the pail. The flanges facilitate the handling of the filled pails on automatic handling apparatus having grab fingers which can engage in the channel between the flanges without disturbing the lid of the pail. The inner surface of the downwardly-depending rim of the lid is formed with a series of axially-extending grooves which, when the lid is applied over the container, define venting spaces between the lid and the outer side of an outwardly-turned bead on the upper edge of the container, thus relieving the pressure of air trapped under the lid as it is applied over the mouth of the container.

Abstract: Platform elements each comprising a porous blanket material are deployed end-to-end to form a continuous traversable pathway through a pool of flammable fluid. The blanket material is heat-resistant and of thickness sufficient to prevent penetration of flame from its top surface to the fluid that is in contact with the bottom surface of the blanket.

Abstract: Spout for a container, e.g. a gasoline can, is formed as a one-piece plastics moulding with a flared skirt on the base formed with a circumferential groove that snap-couples tightly onto a bead on a raised metal neck on the can. A screw-threaded locking collar engages on a screw thread on the spout and can be tightened down to hold the skirt tightly engaged on the bead.
