A disposable portion package for liquids, pastes, creams, powders or the like includes a casing (1,2) made of a flexible film adapted to enclose the packaged substance and also a certain amount of air or other gas. The package has at least one conduit (5) arranged to open by means of pressure produced inside the package, for example by pressing the package between the fingers, in order to obtain the contents for use, preferably as a finely-divided spray. The casing comprises at least two wall parts (1, 2) sealed to each other with the conduit (5) being formed between adjacent layers in a seam (4) connecting the wall parts (1, 2) by weakening the seam in the conduit (5) area so that when the package is pressed the area of the conduit opens to make the substance available for use. The weakening can be formed by including a depression in the sealing tool used to seal the seam (4) so that the seal in the area of the conduit (5) is not as firm as elsewhere. Alternatively a layer of plastics material or a coloured substance to mark the position of the conduit can be applied prior to sealing so that the strength of the seal in the area of the conduit is weakened.
