Blister sheet and blister packaging machine

A blister packaging machine comprising:

• a pocket forming device that forms a plurality of pockets in a container film made of a synthetic resin;
• a filling device that fills a content comprising at least one of a tablet and a capsule in each of the pockets;
• a mounting device that mounts a cover film to the container film with the content filled in each of the pockets so as to close the pockets and produce a blister film, wherein the cover film is thinner than the container film and is made of a synthetic resin;
• a punching device that punches the blister film in a sheet unit;
• a cut forming device that forms at least one pair of cuts for each of the pockets in the blister film, wherein the at least one pair of cuts passes through the container film and the cover film and extends to each of the pockets such that each of the pockets is placed between the one pair of cuts;
• and
• a separation forming device that forms a cutting slit or a cutting perforation in at least the container film, wherein the cutting slit or the cutting perforation extends in a direction perpendicular to at least one of the cuts and allows the blister sheet to separate into sheet pieces, each having a predetermined number of the pockets,
• wherein the separation forming device forms the cutting slit or the cutting perforation such that the cutting slit or the cutting perforation comprises a penetrating part that:
• extends across a point at which the cutting slit or the cutting perforation intersects with at least one of the cuts, and
• penetrates through the container film and the cover film.
