Dispensing device with flow regulator

Abstract

A dispensing device has a tamper resistant enclosure with a primary space containing a first chemical and a flow regulator with a migration pathway in flow communication with the enclosure. The flow regulator is configured to generate a pressure differential between the migration pathway and the primary space to evacuate the enclosure at least partially through an exit pathway. A secondary space may contain a second chemical to be mixed or combined with the first chemical. A primary frangible seal is disposed between the primary space and the flow regulator, and a second frangible seal is disposed between the primary space and the secondary space. The flow regulator may include a priming chamber or a bypass pathway with a one-way valve to create a pressure differential upon breaking the primary frangible seal.
