Abstract
A dual chamber-child-resistant blister package is provided. The blisters of the package include a storage chamber and a discharge chamber. In addition, the blister includes restraint means for preventing the medicament from moving from the storage chamber to the discharge chamber until a predetermined force is applied to the blister package. The medicament may not be dispensed directly from the storage chamber, since a nonrupturable layer is located adjacent the storage chamber of the blister. The nonrupturable layer includes an opening, or a mechanism such as a score line for forming and opening) through which the medicament can pass adjacent the discharge chamber. A rupturable layer is also provided to seal the medicament within the blister. Typically, the rupturable layer is located adjacent the nonrupturable layer to seal the opening in the nonrupturable layer. The blister package may also include indicia associated with the blisters to help insure compliance with complex therapeutic regimens. The blister package may also include fold lines to help reduce the overall size of the blister package; thereby making it easier to transport.
