Abstract:
A child-resistant blister pack that enables separating a plurality of dosage units in a particular order, said pack comprising:(i) a blister film sheet with depressions therein; (ii) dosage forms within the depressions; (iii) a lidding sheet which overlies the depressions and which is secured to the film sheet so as to seal the dosage forms within the depressions; and (iv) a network of lines of weakness in the pack defining the plurality of dosage units, each dosage unit including (a) one of said dosage forms sealed in one of the depressions covered by the lidding sheet and (b) a peel region where part of the lidding sheet is not secured to the blister film sheet, each peel region being disposed adjacent a respective one of the lines of weakness in the network; wherein said lines of weakness include:(1) a first line of weakness extending from a first access point so that, when the first access point is exposed, the blister film sheet and the lidding sheet can be torn along the first line of weakness to expose a second access point wherein the second access point enables access to only a second line of weakness and also to enable access to the peel region of a first dosage unit; (2) wherein the second line of weakness extending from the second access point so that, when the second access point is exposed, the blister film sheet and the lidding sheet can be torn along the second line of weakness to expose a third access point wherein the third access point enables access to only a third line of weakness and also to enable access to the peel region of a second dosage unit; and (3) wherein the third line of weakness which is spaced from the first line of weakness and which extends from the third access point so that, when the third access point is exposed, the blister film sheet and the lidding sheet can be torn along the third line of weakness to enable access to the peel region of a third dosage unit.
