Stand-alone thermoformed blister with break-off opening mechanism
This package design developed by KLOCKE was patented in February 2009 in Europe, USA and Japan for yield-line safety and bracing pack. Yield-line safety
The yield-line / creasing is done partially in the removal area, i.e. no predetermined breaking point to the packing edge. Around the removal area there is a safety frame, which is strengthened by a deep drawn bead. Bracing pack
Before opening of the pack, the safety frame, which is of the same material as the rest of the pack, is bent back. Due to this, the predetermined breaking point is released and opening by breaking-off is possible. As the bent safety frame can be used as stable foot at the same time, the open pack can stand without any problem. So, partial removals are possible.
