[Classes 18, 66 and 94 (i)] A package comprises a carton having four flaps attached to the ends of the front, rear and side walls thereof and a bag or enclosure of film or film-like material having a portion extending outwardly of the carton through the space between the front wall thereof and the side edges of the flaps attached to the side walls when they are folded down to close the carton, the extending portions of the enclosure also extending over the flap attached to the front wall of the carton which flap also extends outwardly thereof so that the extending portions of the enclosure and the flap co-operate to serve. when opened as a spout for discharging the contents of the package. As shown the carton 10 has the two opposite sides scored along the lines 11, 12, the end flaps 4, 5 attached thereto being scored or cut along the lines 4a, 5a and the final closing flap 7 being scored along the line 13 so that whenjthe carton is closed the scoring or dividing lines 12, 13, 4a, 5a are all in one medial plane. The enclosure 2 is formed with ears 3, 3' at the bottom and in closing the bottom of the package, the flap 3<SP>1</SP> is folded over the flaps 4, 5, the flap 3 over the triangular outwardly extending flap 6 of the carton and the final closing flap 7 is adhesively secured to the flaps 4 and 5 and its triangular extension 8 to the flap 6, the package is now filled and the four end flaps at the other end of the package, of a shape corresponding to the flaps 4, 5, are folded down and secured with the folded ears of the bag between them When the contents are to be used the flaps 6, 8 and the point of the ear 3<SP>1</SP> are cut off along the line 9 and by applying pressure to the walls of the carton it may be partly collapsed along the lines 11, 12. 13, 4a, 5a and the contents extruded through the opening formed by cutting along the line 9, the extended portions of the flaps 6, 8 and the ear 3<SP>1</SP> forming a spout. In a modification the front and rear of the carton are also scored along lines connected by scores to the intersections of the lines 11, 12 so that when the scored side walls are pushed together the top and bottom edges of the front and rear respectively move inwards ; in this case the extending ear of the enclosure is disposed between an outer flap of the carton extending from the rear and an extension on a long flap extending from the front of the carton, the ear and the flaps being secured to the top or rear of the package which is opened by lifting the flaps with the ear and severing them. The carton may be formed from a pair of blanks secured together along their outer edges which when the carton is erected form the folding lines down the sides of the carton. When used for liquid the final closing flap of the carton is scored so that it can be squeezed up to form a spout when the carton is opened and the ear of the enclosure cut; openings or perforated parts may be provided in the carton so that the enclosure may be punctured to facilitate the flow of the liquid.
