Abstract
A folding carton is described that includes a hang tab that is slidable between a first position in which the hang tab is tucked behind a first carton panel, and a second position in which the hang tab extends out of the carton for hanging the carton on a display. The carton further includes a hang tab restraint for preventing the hang tab from being pulled entirely out of the carton. The hang tab is initially held in its first position by breakaway nicks that attach the hang tab to the carton. According to further aspects of the invention, the hang tab restraint comprises a yoke flap folded over the hang tab or, alternatively, a tongue member that fits into a central slot of the hang tab.
Claims32
A carton, comprising:
- a hang tab slidable between a first, retracted position in which the hang tab is tucked behind a first carton panel, and a second, extended position in which the hang tab extends out from behind the first carton panel for hanging the carton on a display,
- the carton including a hang tab restraint for preventing the hang tab from extending beyond its second position,
- the hang tab being initially held in its first position by a breakaway attachment that attaches the hang tab to the carton.
A carton blank, comprising:
- a first carton panel;
- a yoke flap extending upward from an upper edge of the first carton panel, the first carton panel and the yoke flap defining between them a yoke opening;
- a glue flap panel extending from a side edge of the first carton panel;
- a hang tab support panel extending from a side edge of the glue flap, opposite the first carton panel;
- a hang tab support and extending upward from the hang tab support panel;
- and
- a hang tab attached by breakaway nicks to the glue flap panel and the hang tab support arm,
- the hang tab being positioned with respect to the yoke opening and glue flap panel such that when the glue flap panel is folded into position for gluing, the hang tab is aligned underneath the yoke opening, with an upper portion of the hang tab protruding through the yoke opening when the yoke flap is folded down over the hang tab.

- a hang tab support panel extending from a side edge of the glue flap, opposite the first carton panel;
- and
- a hang tab attached by breakaway nicks to the hang tab support panel,
- the hang tab being positioned with respect to the yoke opening and glue flap panel such that when the glue flap panel is folded into position for gluing, the hang tab is aligned underneath the yoke opening, with an upper portion of the hang tab protruding through the yoke opening when the yoke flap is folded down over the hang tab.

A carton blank, comprising:
- a first carton panel;
- a yoke flap extending upward from an upper edge of the first carton panel, the first carton panel and the yoke flap defining between them a yoke opening;
- a hang tab extending upward from the yoke flap, attached to the yoke flap by breakaway nicks;
- the hang tab being positioned with respect to the yoke opening and glue flap such that when the hang tab is folded down over the yoke flap and the hang tab and yoke flap are folded down over the first carton panel, the hang tab is aligned underneath the yoke opening, with an upper portion of the hang tab protruding through the yoke opening.
1 more element
A carton blank, comprising:
- a first carton panel;
- an inverted hang tab extending upward from the first carton panel, the hang tab including a central slot;
- a tongue member extending from the first carton panel, the tongue member positioned relative to the hang tab such that when the hang tab is folded downward over the tongue member, the tongue member is aligned with the hang tab central slot so that the tongue member engages the hang tab central slot to limit the vertical movement of the hang tab.
A carton blank, comprising:
- a first carton panel;
- an inverted hang tab extending upward from the first carton panel, the hang tab including a central slot;
- a tongue member extending from a supporting frame extending from a second carton panel, the tongue member positioned relative to the hang tab such that when the hang tab and supporting frame are folded into position, the tongue member is aligned with the hang tab central slot so that the tongue member engages the hang tab central slot to limit the vertical movement of the hang tab.
A method for manufacturing a carton, comprising the following steps:
- (a) attaching a hang tab to a carton blank by breakaway nicks, the hang tab having a pair of shoulders and a narrower head section;
- (b) positioning the hang tab underneath a yoke flap extending from a first carton panel, the yoke flap having an opening therein dimensioned to allow the hang tab head section to pass therethrough, the yoke flap opening having side sections that prevent the hang tab from passing all the way through the opening by engaging the hang tab shoulders;
- and
- (c) folding the yoke flap over the hang tab, such that an upper portion of the hang tab protrudes from the opening.
