Fully enclosed wrap-around carton
View Patent ↗A fully enclosed pack is provided with a gusset that is capable of being formed from a blank without the use of tucker fingers. Nicks are provided between the side end panel and tuck-in panels of the carton. As the side end panels are folded, the nicks help pull the tuck-in panels inwardly to allow the gusset of the carton to take form without the use of tucker fingers in a folding/gluing operation.

webs respectively connected to the top end panels by fold lines, wherein each web includes a tuck-in panel, a gusset panel, and a nick,
the tuck-in panels are respectively adjacent the side end panels,
for each web, the nick of the web is formed between the tuck-in panel of the web and the side end panel that is adjacent to the web, and for each web, the nick of the web comprises a space between the tuck-in panel of the web and the side end panel that is adjacent the web, the space includes carton material that is substantially free from fold lines or other lines of weakening,
the nicks are operative for respectively pulling the tuck-in panels inwardly during formation of the carton, and
each nick is proximate both a respective lateral fold line of the lateral fold lines and a respective longitudinal fold line of the longitudinal fold lines.
4. The carton according to claim 3 wherein the respective lateral fold line and the respective longitudinal fold line intersect and a portion of the respective lateral fold line extends laterally beyond the intersection to a lateral end thereof, the space of each nick being between the lateral end of the respective lateral fold line and the outer periphery of the carton.
5. The carton according to claim 3 further comprising an opening between a respective upper side panel and the respective web to facilitate folding.
6. The carton according to claim 3 wherein the at least one bottom panel comprises two bottom panels folded into a closed position, each of the two bottom panels being respectively connected to one of the lower side panels.
7. The carton according to claim 3 further comprising a plurality of bottles disposed within the carton.
8. The carton according to claim 3 wherein each top end panel includes a foldably connected top end panel flap.
9. A blank for forming a carton, comprising:
a top panel;
upper side panels connected to the top panel;
lower side panels respectively connected to the upper side panels at respective lateral fold lines;
at least one bottom panel connected to at least one of the lower side panels;
top end panels respectively connected to sides of the top panel;
side end panels respectively connected to sides of the lower side panels at respective longitudinal fold lines, the side end panels extending to respective lateral edges positioned further from the center of the blank than respective lateral edges of the top end panels; and
webs respectively connected to the top end panels by fold lines, wherein each web includes a tuck-in panel, a gusset panel, and a nick,
the tuck-in panels are respectively adjacent the side end panels,
for each web, the nick of the web is formed between the tuck-in panel of the web and the side end panel that is adjacent to the web, and for each web, the nick of the web comprises a space between the tuck-in panel of the web and the side end panel that is adjacent the web, the space includes carton material that is substantially free from fold lines or other lines of weakening,
the nicks are operative for respectively pulling the tuck-in panels inwardly during formation of the blank into the carton, and
each nick is proximate both a respective lateral fold line of the lateral fold lines and a respective longitudinal fold line of the longitudinal fold lines.
10. The blank according to claim 9 wherein the respective lateral fold line and the respective longitudinal fold line intersect and a portion of the respective lateral fold line extends laterally beyond the intersection to a lateral end thereof; the space of each nick being between the lateral end of a respective lateral fold line and the outer periphery of the carton.
11. The blank according to claim 9 further comprising an opening between the respective upper side panel and a respective web to facilitate folding.
12. The blank according to claim 9 wherein the at least one bottom panel comprises two bottom panels folded into a closed position, each of the two bottom panels being respectively connected to one of the lower side panels.
13. The blank according to claim 9 wherein each top end panel includes a foldably connected top end panel flap.
14. A method of forming a carton from a blank, comprising:
providing a blank comprising: a top panel; upper side panels connected to the top panel; lower side panels connected to the upper side panels at respective lateral fold lines; at least one bottom panel connected to at least one of the lower side panels; side end panels respectively connected to the lower side panels at respective longitudinal fold lines; top end panels respectively connected to sides of the top panel, and webs respectively connected to the top end panels by fold lines, wherein each web includes a tuck-in panel, a gusset panel, and a nick, the tuck-in panels are respectively adjacent the side end panels, for each web, the nick of the web is formed between the tuck-in panel of the web and the side end panel that is adjacent to the web, the nicks are operative for respectively pulling the tuck-in panels inwardly during formation of the blank into the carton, and each nick is proximate both a respective lateral fold line of the lateral fold lines and a respective longitudinal fold line of the longitudinal fold lines;
