The invention herein relates to a method and apparatus for forming (or cold-forming) an embossed blister from a laminated film wherein an indicia is formed on the base of the blister. In particular, the invention involves a single pass process of combining the formation of a blister and the formation of an indicia (embossing) on the blister, wherein the blister-forming pin contains a face with an indicia and is adapted to controllably stretch the laminated film during blister formation to minimize stretching of the film at the base of the blister. The invention is particularly useful in manufacturing processes which involve the formation of blisters having laminated films which contain a metal foil and polymer layer, wherein improved control in the stretching of the laminate during blister formation is desirable.

Apparatus for making embossed blister pack

Method and apparatus for making a blister pack with indicia

A blister pack which confines the movement a dosage form in order to resist damage thereto during handling and transportation while permitting removal of the intact dosage form, and apparatus and methods for the same. In particular, the invention provides a blister pack wherein the blister includes a protruding region between the opening and the base, thereby producing a constricted area or &ldquo;neck&rdquo; in the blister. In a preferred embodiment, the protruding region comprises an inwardly directed annulus formed in the blister wall. Accordingly, vertical movement of the dosage form is confined as a result of the protruding region, thereby reducing the likelihood of damage to the dosage form caused by agitation of the blister pack. The invention is particularly useful in packaging frangible pharmaceutical dosage forms formed in situ within the blister, such as freeze dried dosage forms and rapidly dissolving oral dosage forms.
