A blister-type packaging unit having a front wall (2) and a rear wall (1) defining an article-receiving space (6) between them. The front wall (2) and the rear wall (1) have a circumferential joint (4). Inwardly of said circumferential joint (4) a weakened region (7) is present in at least one of the front and rear walls (1,2), which weakened region (7) is tearable by a user to separate the front and rear walls (1,2). Said weakened region (7) has two end portions which are located inwardly of said peripheral region, so that the weakened region (7) can be torn after the user has made a cut in the walls (1,2). |

1. A blister-type packaging unit, comprising:
a single layer front wall, and a single layer rear wall defining an article-receiving space between them, whereby both the front and rear walls are made of plastic and the front wall is transparent, the front wall comprised of a single section defining a front face of the blister-type packaging unit and the rear wall comprised of a single section defining a rear face of the blister-type packaging unit, a horizontal slot-like opening located in the front wall having a corresponding opening in the rear wall extending in a downward direction, wherein the front wall and the rear wall have a circumferential joint along at least a main portion of a peripheral region of the front and rear walls, wherein inwardly of said circumferential joint one or both of said walls includes weakened regions consisting of a first weakened region and a second weakened region located in opposite parts of the peripheral region being separated there-between by a non-weakened region, wherein said first and second weakened regions each respectively have end portions which are located inwardly of said circumferential joint, wherein a cutting line near a further part of the peripheral region between said opposite parts crosses both of said first and second weakened regions in said opposite parts of the peripheral region, wherein the horizontal slot-like opening centrally bifurcates said cutting line thereby providing an opening to allow a user to insert a finger through said corresponding opening in the rear wall, wherein said first and second weakened regions are tearable by said user to separate the front and rear walls in order to access said article-receiving space, and wherein the first and second weakened regions can be separately torn by the user after the user has made a cut along the cutting line in the front and rear walls starting from said peripheral region through said two end portions of said first and second weakened regions. |
