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

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. The abutments are discontinuous so that gaps for a levering tool are retained.

A container and lid combination in which the container has a base, a side wall or walls and an open end opposite to the base defined by a peripheral flange extending inwardly with respect to the side wall or walls and downwardly towards the base, and the lid has a closure part which is a sealing fit

A container and lid combination in which the container has a base, a side wall or walls and an open end opposite to the base defined by a peripheral flange extending inwardly with respect to the side wall or walls and downwardly towards the base, and the lid has a closure part which is a sealing fit within the peripheral flange wherein the container comprises two components each integrally moulded from plastics material and secured together, the said components being a top component including said peripheral flange and having lid-retaining means adjacent to its periphery and independent of the peripheral flange for engaging complementary means on the lid when the closure part of the lid is fitted within the peripheral flange, and a bottom component including the base of the container, at least one of the said components having an integral wall part which comprises the side wall or walls of the container or part of the side wall or walls.
