Child-proof package system

Abstract

A sealed package system includes multiple sealed units separably interconnected to each other by tear lines, said units including opposed, substantially planar, tear-resistant flexible plastic sheets sealed to each other, preferably by heat sealing, about peripheral seal zones of the units to provide each unit with a central compartment adapted to retain and protect a material therein, seal zones between adjacent compartments including the tear lines for permitting separation of discrete sealed units from each other without disrupting the sealed integrity of the compartments thereof, each tear line including a substantially linear, continuous slit uninterrupted by bridge areas and being linearly aligned with the compartments in adjacent units interconnected by said tear line, the linear dimension of each of said continuous slits being greater than the greatest linear dimension of the linearly aligned compartments, as measured substantially parallel to said continuous slit.
