Abstract: A convenient stopper for a bottle including a plug slidably retained in a cylinder by a connecting pin. The cylinder is sized to be received in an opening of the bottle. In a contracted mode of the stopper, the plug is disposed at the top of the connecting pin and away from the cylinder, whereby an outer wall of the cylinder contracts from the neck of the bottle, to allow easy removal from the bottle, without use of a corkscrew. In an expanded mode of the stopper, the plug is urged into the cylinder whereby the outer wall of the cylinder tightly seals the opening of the bottle. The stopper can be re-used to permit storage of remaining contents of the bottle to be consumed later.

The container can be squeezed, inverted or shaken to force an amount of material from the first compartment and into the second compartment through the gap. The second compartment may be friction fit or snap fit within the first end of the first compartment, while retaining the gap between the outer wall of the second compartment and the side wall portion of the first compartment.

Abstract: A combination closure is provided, particularly for evacuated collection tubes for body fluids such as blood, including an elastomer stopper and plastic cover combination with cooperating locking surfaces spaced around the circumference thereof. The stopper includes vertically spaced sealing rings for insertion into the open end of the tube. Also, the stopper includes a plurality of circumferentially spaced protrusions and the cover or shield cooperating circumferentially spaced indentations or ports to provide a locking force between the protrusions and indentations. As a result, the dimensions of the stopper and the plastic cover are reduced, which in turn reduces the penetration force required to insert a needle through the stopper. Moreover, the reduced dimension of the closure allows it to be locked to a bead on the tube whether plastic or glass, and the lesser overall diameter allows the closure on the tube to fit more tube holders or containers during and prior to use.
