Abstract
A device for storing and dispensing a substance includes a storage chamber for the substance. The container includes a passageway in fluid communication with the storage chamber. The container includes a pierceable wall located on an opposite side of the passageway relative to the storage chamber. The device includes a one-way valve assembly including a piercing portion. At least one of the piercing portion and the pierceable wall is movable relative to the other between a first position wherein the pierceable portion is not piercing the pierceable wall, and a second position wherein the pierceable portion is piercing the pierceable wall allowing the flow of substance from the storage chamber. A removable member is disposed intermediate the valve and the container that prevents movement of at least one of the piercing portion and pierceable wall to the second position until the removable member is removed.
