CLOSURE FOR RESEALABLE PACKAGE

摘要

A closure mechanism for use with bag or sachet-like packaging (5) which is substantially formed by opposing sheets (10, 15); wherein said closure mechanism includes first and second sets of opposing substantially parallel ridges (40, 45), said ridges defining complementary grooves (60) therebetween that are adapted to receive said opposing ridges in a form-locking engagement; wherein the surface of said ridges and grooves feature a plurality of ribs (65)extending traverse and from said surfaces such that, when said first form-locking engagement is made, the ribs extending from said ridges tend to interfere with the ribs extending from said grooves thereby to impede unintentional opening of said closure.
