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. This layer provides improved retention of flavor while still allowing the sachet to be readily torn once a tear has been initiated.

An improved package, suitable for holding a treatment fluid comprising a volatile solvent and kits comprising the package containing the treatment fluid and an applicator are disclosed. The package comprises a reservoir for the liquid which is sealed by a ruturable seal. A cap, coupled to one end of the reservoir, is in the form of a sleeve which is axially translatable along the reservoir from first to second positions. A cutting tool integrated with the cap ruptures the rupturable seal as the cap is moved from first to second positions so that the liquid can thereby be made accessible through an opening in an end wall of the cap. The package provides excellent protection for volatile liquids, yet can be easily opened by a simple press-action, instantly providing access to the liquid so that it can subsequently accessed by a liquid applicator.
