Abstract
A transdermal reservoir and method for loading a material into a reservoir includes providing a bibulous reservoir blocking a backing with an interior surface having a patient contact surface with a shape disposed on the interior surface of the backing. A closure is sized and shaped to engage the backing for forming a releasable seal to isolate the bibulous reservoir from the ambient environment. The closure has an inside surface with a section of an absorbent material disposed thereon. When the closure is disposed on the backing, the absorbent material is positioned in intimate physical contact with the reservoir. The method includes applying an aliquot of a material to the absorbent material,. placing the closure on the backing so that the absorbent material is in intimate physical contact with the contact surface of the bibulous reservoir and the closure forms the releasable seal with the backing. The reservoir is allowed to stand for a sufficient time to allow the aliquot to be absorbed into the bibulous material thereby loading the reservoir.
