connection to any other part of the carton, the first and second corner edges extending from the first and second sides of the top panel respectively, wherein the carton comprises a first severance line extending from the first corner and a second severance line extending from the second corner edge and the top panel comprises a third severance line extending between the first and second severance lines. ### Claim 2 (depends on 1) A carton according to claim 1, wherein the first severance line extends into the first side panel from the first corner edge to the first side of the top panel, the second side panel comprises a second severance line extending into the second side panel from the second corner edge to the second side of the top panel. ### Claim 3 (depends on 1) A carton according to claim 1, wherein the first severance line extends from the first corner edge along a hinged connection between the first side panel and the first side of the top panel, the second side panel comprises a second severance line extending from the second corner edge along a hinged connection between the second side panel and the second side of the top panel. ### Claim 4 (depends on 1) A carton according to claim 1, wherein the top panel comprises a free end edge extending between the first and second corner edges, the free end edge being free of hinged connection to any other part of the carton. ### Claim 5 (depends on 1) A carton according to claim 1, wherein the first and second end closure panels are hingedly connected to end edges of the first and second side panels respectively, and wherein the end edges of the first and second side panels extend from the first and second corner edges respectively. ### Claim 6 (depends on 4) A carton according to claim 4, wherein the free end edge of the top panel is inset from an end edge of either one of the first and second side panels, the end edges of the first and second side panels extending from the first and second corner edges respectively. ### Claim 7 (depends on 5) A carton according to claim 5, wherein the top panel comprises a first tab integrally formed therewith, the first tab extending between the top panel and the first and second end closure panels. ### Claim 8 (depends on 7) A carton according to claim 7, wherein the first tab comprises first and second free side edges, the first and second free side edges being free of hinged connection to any other part of the carton. ### Claim 9 (depends on 7) A carton according to claim 7, wherein the first tab forms a part of a detachable portion for forming a dispenser for facilitating access to the carton contents. ### Claim 10 (depends on 8) A carton according to claim 8, wherein the top panel comprises first and second hinged connections to the first and second side panels respectively, and wherein the first and second free side edges are inset from the first and second hinged connections respectively. ### Claim 11 (depends on 1) A carton according to claim 1, wherein the top panel comprises a first hinged connection to the first side panel, the first hinged connection being shorter in length than the length of the first side
