Profiled interlocking closure strap with wedge-shaped parts.

摘要

A reclosable bag is formed of walls defining a closure with a mouth. The walls have interlocking profiles (32,34) on their internal surfaces adjacent to the mouth to enable the bag to be sealed. One of the two profiles has a spreader (30) which fits between and spreads the interlocking members on the other profile (34) to bring about a more effective sealing of the bag.
