Abstract: A container with a lid has a base, a side wall and an open top which the lid closes. It is made by separately moulding in plastics the base and the ring defining the open top, with the side wall being moulded integrally with one or both of these parts, and then joining the parts together by bonding or welding. The top ring is moulded with a flange which extends inwardly and downwardly and receives a mating closure flange on the lid to give a resilient sealing fit.The lid may be a snap-on fit having a skirt with an inward bead or groove for engaging a complementary groove or bead on the container. The skirt may be accommodated in a rebate at the top of the container and may be levered away from the lower shoulder of the rebate to remove the lid. Damage to the seals between the lid and the container due to excess force exerted in machine fitting of the lids is avoided by abutments located in the rebate for preventing excess movement of the skirt of the lid.

Abstract: A facing or lining material of a thermoplastic such as polypropylene is provided with a key fabric bonded to its reverse face so that a reinforcing material such as fibre-reinforced resin or hydraulic cement can be bonded to it. The key fabric is a pile fabric made for example by tufting, and the pile fibres can be embedded in the reinforcement material to provide a strong bond. Glass fibres are suitable for the pile and are made of alkali-resistant glass for use with cement reinforcement. The composite material can be used for lining vessels, tanks, ducts and pipes in chemical plant and as an external or internal facing material for buildings.
