A container (1) of the kind formed with an open void (3) separate from the main containment volume thereof characterised in that selectively removal means (6) are provided to substantially close said void (3) thereby defining a second containment volume (8). Any desired material, such as printed promotional material (9), coupons, operating instructions, spare parts, or even a second active ingredient may be packaged with the container (1). The selectively removal means may take the form of a membrane and may be adhered directly to the rim (3) or at an edge (5) located between the rim (4) and the depression (3). The membrane may be located at the top of a ring pull can in which case the second containment volume (8) covers the ring pull so as to provide a can top and ring pull free from contamination.
