ABSTRACT:
A sachet [(10, 22, 110, 210, 510)] for the packaging and dispensing of an item or a flowable substance [(125)], such as a liquid, powder or paste, has a semi-rigid member [(112)] with a weakened region [(120)] formed thereon so that upon bending across the weakened region [(120)] the semi-rigid member [(112)] will fracture along the weakened region [(120)]. The sachet [(110)] also has a reservoir [(114)] formed by overlaid first and second flexible film layers [(116,118)] which are adapted to contain the flowable substance [(125)]. In one form, an annular region [(128)] of the second flexible film layer [(118)] immediately surrounding the aperture region [(126)] is sealed to the adjacent region of the semi-rigid member [(112)] so as to prevent leakage of the flowable substance [(125)] from within the reservoir [(114)]. In use, fracturing along the weakened region [(120)] will expose the aperture [(126)] so as to allow the flowable substance [(125)] to be dispensed.
