Abstract:
Provided is a blister sheet, etc. that is provided with a child resistance function and with which prevention of various kinds of cost increases, etc. can be more reliably achieved. The blister sheet 1 comprises a container film 3 provided with pocket sections 2, and a cover film 4 attached to the container film 3 so as to seal the pocket sections 2. The two films 3, 4 are made of synthetic resins and the cover film 4 is thinner than the container film 3. In the blister sheet 1, at least one pair of incisions 8, which penetrate the two films 3, 4 and extend almost to the pocket sections 2, is formed for each pocket section 2. By applying a torsional stress from a pair of incisions 8 toward a pocket section 2, the two films 3, 4 are ruptured from the incisions 8 toward the pocket section 2 and at least the cover film 4 is ruptured at a position corresponding to the pocket section 2, making it possible to remove a tablet 5 from the ruptured portion of the cover film 4.
