In an arrangement of a container ( 10 ) and a closure ( 11 ); the container ( 10 ) has a base ( 13 ), a peripheral wall ( 15 ), a rim ( 16 ) forming an upper margin of the wall and surrounding an opening of the container, and a flange ( 19 ) formed integrally with and extending out from the wall below the rim; the closure has a central portion ( 14 ) that is arranged to overfit the opening of the container ( 10 ), and a skirt ( 26, 29, 31 ) formed integrally with the central portion and arranged to surround the rim ( 16 ) when the closure is fitted to the container. The skirt is positionable adjacent to the flange when the closure is fitted to the container. A plurality of discrete projections ( 70 ), each extending from the skirt, and each being insertable into a respective opening in the flange are arranged such that, once a given projection has been inserted into a respective opening ( 72 ) in the flange, a portion ( 74, 94 ) of that projection is caused to assume an orientation by a corresponding formation ( 85, 100, 101 ) of the flange, or a portion ( 81 ) of the flange is caused to assume an orientation by a corresponding formation ( 73 ) of the projection, such that removal of that projection from the opening is resisted.
