Abstract: The present invention relates to an improved child resistant sachet construction, suitable for holding a medicinal product, especially a flavored product. The sachet is a three seal sachet, or stick pack, made from a laminate sheet, the sachet having a fin seal along a longitudinal axis and transverse fin seals at each end. The laminate sheet is tough enough to resist tearing unless a notch is provided with which to initiate a tear. A fold line extends across a corner of the sachet and through the fin seal, a notch extending through the sachet in a transverse seal area and perpendicular to the fold line such that when the sachet is folded a cut is revealed that allows the user to initiate a tear across the pack opening up a pouring spout for dispensing the medicinal product. In an alternative aspect of the invention the laminate sheet is provided with an acrylonitrile methyl acrylate copolymer resin on the sheet face which forms the inside of the sachet.
