ABSTRACT:
The invention is a child resistant and easy to use blister package for containing a solid medicament that utilizes a push through and peel mechanism as an opening feature. The multi-section blister card package has an opening mechanism featuring a cut-out in the blister container sheet which is adjacent to the cavity containing the product and a corresponding weakened area such as a perforation or score in the closure sheet positioned slightly inside and adjacent to the edge of the cut-out in the container sheet. The blister is opened by pushing through the closure sheet at the perforation to form a pull-tab which can be used to peel the closure sheet from the container sheet towards the product cavity thereby exposing the product cavity to remove the product.
