Abstract: A plastic lid for a pail. The lid has a substantially planar central section and a peripheral channel. The channel fits over the pail to effect closure thereof. The central section is spaced from the channel by a groove and a ridge, each of which extend around the lid juxtaposed to the channel, with the groove being adjacent to the channel. The pail is intended for transportation of goods.

Abstract: A pail lid having a retractable pouring spout. The pail lid has a neck integrally formed as part of the lid and extending from the face of the lid opposed to a peripheral groove. The neck has external threads adapted to receive a screw cap. A retractable pouring spout located within the opening is movable from a pouring position to a retracted position while being retained within the neck. The spout mates with the neck at the pouring position and the retracted position. An injection molding process for manufacture of the lid is also disclosed.

Abstract: A helmet for the protection of sportsmen and/or workers in potentially hazardous occupations is disclosed. In one embodiment the helmet comprises a protective head shell and means to position the helmet on a users head in which the head shell has an outer section slidably connected to an inner section. The outer section is adapted to move relative to the inner section on impact with an object. In another embodiment the helmet further comprises a plurality of cushioning projections located between the two shells, each projection being integrally connected to one of the shells.

Abstract: An ethylene polymer having a density in the range of about 0.940-0.960, a melt index in the range 100-200 and a ratio of weight-average molecular weight to number-average molecular weight of less than 5 is disclosed. The polymer is a copolymer of ethylene and at least one .alpha.-olefin having 4-10 carbon atoms, e.g., butene-1, hexene-1 or octene-1. The preferred polymer is a copolymer of ethylene and butene-1. The polymers may be used in the injection moulding of thin-wall containers, e.g., containers having a wall thickness of less than 0.7 mm, especially a thickness of less than 0.5 mm and in particular a thickness of less than 0.4 mm.
