There is disclosed a closure, more particularly but not exclusively used for blood sampling tubes. The closure comprises a core section of elastomeric material constructed and arranged to be received at least partially within the tube, i.e., the container, and an annular outer section of substantially non-elastomeric material disposed radially of the core section. The annular section is spaced from the core section over a part of its length to provide an annular recess for receipt of the container neck.
