Abstract
There is described a package and method of packaging that provide, in inexpensive form, means for adding accurate amounts of one material to another. The package, which can come as a kit to be added to a lyophilizing bottle and stopper, features a portion that is added to the bottle outlet to confine the material that is to be stored separate from the contents of the bottle. That portion includes a plunger preferably constructed to provide a dual function: that of sealing the stopper against the bottle outlet, and of permanently attaching to the stopper to remove it from the bottle when the plunger is moved within the upper portion. Because of its hollow configuration, the plunger can be used to pour off the resulting mixture.
