Carton blank for direct injection molded closures

A carton blank for use in a form, fill and seal packaging machine for forming, filling and sealing a carton, the machine configured to mold a closure directly onto the carton, the machine including a tool set having first and second tool elements, the first tool element having an aligning member extending therefrom in a direction transverse to a direction of loading the carton between the first and second tool elements, the aligning member having a predetermined shape having diverging surfaces, the carton blank comprising:

• a rear wall panel, a first side wall panel, a front wall panel and a second side wall panel, each panel separated from its adjacent panels by a vertical score line;
• a closure panel adjacent the front wall panel, the closure panel partitioned from the front wall panel by a first horizontal score line, the closure panel having a closure panel fin panel extending from a side opposite the front wall panel, the closure panel fin panel having a height measured to an edge of the fin panel, the closure panel configured for having a closure molded thereon;
• and
• a first upper side panel adjacent the first side wall panel, the upper side panel being adjacent the closure panel, the first upper side panel having a first upper side panel fin panel having a height, means, located on the closure fin panel, for laterally aligning the carton with the first tool.

A carton blank for use in a form, fill and seal packaging machine for forming, filling and sealing a carton, the machine configured to mold a closure directly onto the carton, the machine including a tool set having first and second tool elements, the first tool element having a stop surface extending therefrom for preventing over-insertion of the carton in a direction of loading the carton between the first and second tool elements and including an aligning member formed in the stop surface, the aligning member having a predetermined shape, the carton blank comprising:

• a rear wall panel, a first side wall panel, a front wall panel and a second side wall panel, each panel separated from its adjacent panels by a vertical score line;
• a closure panel adjacent the front wall panel, the closure panel partitioned from the front wall panel by a first horizontal score line, the closure panel having a closure panel fin panel extending from a side opposite the front wall panel, the closure panel fin panel having a height measured to an edge of the fin panel, the closure panel configured for having a closure molded thereon;
• and
• a first upper side panel adjacent the first side wall panel, the upper side panel being adjacent the closure panel, the first upper side panel having a first upper side panel fin panel having a height,
• the closure panel fin panel having a formation therein for mating with the first tool element aligning member to laterally align the carton with the first tool element as the carton contacts the stop surface and is longitudinally positioned relative to the first tool element by engagement with the stop surface carton.
