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