摘要

The sachet (10) has a sealing system comprising complementary male (12) and female (22) profiles. It is sealed by moving a slide (100) with a U-shaped cross-section along its top so that the walls (120, 130) of the slide squeeze the profiles together. The slide is held on by e.g. simple friction or grooves on the inside of its walls which fit on to ribs on the sachet. An Independent claim is included for the guide.
