A container for containment of bituminous products formed by inner and outer flexible casings in intimate contact. The inner casing is of a material which has a softening temperature which is above that of the bituminous product when loaded into the container but below that of the bituminous product when it is applied in use, usually by spraying. This inner casing material has a viscosity at the application temperature which enables the material when melted with the bituminous product to be applied therewith. The outer casing is made from a material which has strength characteristics which enable it to contain the inner casing and bituminous product during the filling of the container as well as during transportation and storage thereof. The outer casing is impervious to movement therethrough of the contained bituminous product, components or additives thereof and preferably has a softening temperature such that melting does not occur at the application temperature.
