What is claimed is: 1. A carton for holding a plurality of articles, comprising a collapsible tubular corner post having an essentially triangular cross-section, said corner post being formed from a series of hingedly interconnected panels including an end panel, a bracing panel and a securing panel, said end panel being hingedly connected to a side wall of the carton along a first fold line, said securing panel being secured to an inside surface of said side wall, wherein said end panel comprises a supplementary fold line disposed parallel to said first fold line to allow said corner post to be folded flat into a collapsed condition where said corner post extends outwardly of the carton, said first and supplementary fold lines extend along a tubular axis of said corner structure, said bracing panel is hingedly connected to said end panel along a second fold line parallel to said supplementary fold line, said securing panel is hingedly connected to said bracing panel along a third fold line, and said third fold line is curved convexly toward said second fold line to assist in flexing said bracing panel. 2. A carton as claimed in claim 1 wherein said end panel is secured in part to an end flap of the carton to close the carton. 3. A carton as claimed in claim 1 wherein the distance between said first and supplementary fold lines is greater than the distance between said supplementary and second fold lines. 4. A carton as claimed in claim 3 wherein the distance between said first and second fold lines is less than the distance between said second and third fold lines. 5. A blank for forming a carton for holding a plurality of articles, said blank comprising a side wall and a series of hingedly interconnected panels for forming a triangular tubular corner post upon erection of a carton, said interconnected panel including an end panel, a bracing panel and a securing panel, said end panel being hingedly connected to said side wall along a first fold line, said securing panel being adapted to be secured to said side wall upon erection of a carton, wherein said end panel comprises a supplementary fold line disposed parallel to said first fold line to allow said corner post to be folded flat into a collapsed condition, said bracing panel is hingedly connected to said end panel along a second fold line parallel to said supplementary fold line, said securing panel is hingedly connected to said bracing panel along a third fold line, and said third fold line is curved convexly toward said second fold line to assist in flexing said bracing panel upon erection of a carton. 6. A blank as claimed in claim 5 wherein the distance between said first and supplementary fold lines is greater than the distance between said supplementary and second fold lines. 7. A blank as claimed in claim 6 wherein the distance between said first and second fold lines is less than the distance between said second and third fold lines. 8. A carton for holding a plurality of articles, comprising a reclosable tear open flag defined at least in part in a first wall of the carton by a tear line, and a wall end-reinforcing member hinged to said first wall, wherein said reinforcing member is affixed at least in part to an inside surface of said first wall so that said reinforcing member underlies said first wall along at least a part of said tear line, wherein said reinforcing member is disposed astride said tear line so that a part of said reinforcing member underlies said tear open flap to provide upon breaking of the tear line an engaging element for retaining said tear open flap in a reclosed position. 9. A carton for holding a plurality of articles, comprising a reclosable tear open flap defined at least in part in a first wall of the carton by a tear line and an engaging panel affixed at least in part to an inside surface of said first wall wherein said engaging panel is disposed astride said tear line to provide upon breaking of said tear line an engaging element for retaining said tear open flap in a reclosed position, and wherein said engaging panel is provided by a corner structure disposed between said first wall and a second wall of the carton, said first and second walls being disposed adjacent to each other to define a corner of the carton therebetween, said corner structure being affixed to an inside surface of said second wall and extending to said first wall to be affixed to said first wall. 10. A carton as claimed in claim 9 wherein said corner structure comprises a first panel affixed to said first wall and a second panel affixed to said second wall, and said engaging panel is provided by said first panel. 11. A carton as claimed in claim 10 wherein said first and second panels underlie said first and second walls respectively to reinforce said corner. 12. A carton as claimed in claim 9 wherein said tear open flap comprises primary portion formed from said first wall and a secondary portion hingedly connected to said primary portion and formed from a third wall of the carton disposed adjacent to said first and second walls. 13. A carton as claimed in claim 9, wherein said first wall is provided with a retaining tab hingedly connected thereto, and a portion of said tear open flap is adapted to be placed intermediate said first wall and said retaining tab to be retained therewith.
