Abstract
A single-use, multi-chamber package for housing and common administration of at least two flowable substances. The package includes at least first and second product storage cavities; and at least first and second product application channels. At least one separation line selectively reduces the strength of a predetermined area of the package and generally defines a tab. Steps of use include: 1) applying a force to tab creation areas to separate a portion of a tab; 2) removing the tab from the blister package by tearing across the product application channels to form wings, exposing the interior of the product application channels; 3) rotating the wings to pivot the channel openings toward one another, and 4) applying a force to the storage cavities to dispense the products. The package may contain more than two substances by employing multiple storage cavities and application channels.
