  • Patent number: 4347943
    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.
