Rohrer have been working on a unit dose blister pack with a twist. It is common to have unit dose blister packs with a variety of opening methods. (for example, the Swiss machinery company is just delivering a blister line with robotic loading of unit dose blister with a biologic unit pack.) There are even systems with two forms with different products which are opened together and applied or taken at the same time. But Rohrerâ€™s innovation is to design a blister which actively mixes the two ingredients as they are squeezed out of the blister. This is thought to be a unique system in disposable unit packs. Such a double blister with active mixing is thought to be applicable in such fields as combination drug therapies, drugs which cannot be mixed in transit, animal health applications and novel cosmetic disposable single use packs.
