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. |
