BLISTER PACKS

摘要

A blister pack (10) comprises a blister sheet having at least one row of blisters (12) and a cover sheet (11) laid over and bonded to the area of the blister sheet which surrounds the blisters. The cover sheet is burstable by pressure applied through a blister to a product therein, so freeing the product. A label (13) is applied to the cover sheet (11), which label provides a security strip (14, 15, 24) extending over each blister (12), the strip having sufficient strength to resist bursting of the cover sheet unless at least one end of the strip is mostly freed from the surrounding areas of the cover sheet. That one end may be mostly freed by cutting away the strip at one end of the pack or by using a peel-tab (31) to lift up the strip (24) adjacent the end blister (17) of a row.
