A container system includes an elongate, open-ended tubular container member defining an axis and a releasable stop device for at least one open end thereof. The releasable stop device comprises a one-piece integrally formed member having first and second legs joined along a common edge to define an acute angle. The two legs are resiliently compressible about the joined edge, and a further abutment surface extends integrally from the first leg. The second leg is formed for attachment in a generally flat, surface-to-surface condition with an outer sidewall surface of the tubular container member at an open end portion thereof, such that the first leg and the abutment surface extend retractably into the tubular container member. The invention also extends to the stop device itself.
