Multi-Compartment Package

Abstract

A package comprising a body comprising a first compartment containing a first substance and a second compartment containing a second substance. The package includes a first state in which the first compartment is isolated from the second compartment such that the first substance is separated from the second substance, and a second state in which the first compartment communicates with the second compartment such that the first substance and the second substance combine.
