Abstract
A nestable container of resilient plastics material comprises integral bottom and side walls, the side walls diverging generally from the bottom to the top. The container has means for holding the containers together in a stack, comprising projections which provide pairs of mutually opposed shoulders on the outside of the container and projections on the inside of the container. The space between the shoulders of each pair is slightly less than the width of each projection on the inside of the container so that when such identical containers are brought together the shoulders on one container are displaced circumferentially to allow the projections on the inside of the other container to pass between them and engage behind them holding the cups together.
