A resealable cap for a container is disclosed, the cap having a seal piercing element, the liquid in the container being initially separated from the piercing element by a seal. The cap includes a collar, a neck portion and a top portion. The top portion includes the seal piercing element. There is a liquid passageway through the cap, after the top portion has been moved from an initial position to a closed position (thus piercing the seal) and thence to an open position. Thereafter the cap can be resealed and opened repeatedly, by movement of the top portion from the open position to the closed position and vice versa. Numerous embodiments of the invention are disclosed. |
