Abstract

A sleeve-style beverage carton for use on a carton filling machine having traveling flight bars is disclosed. The carton may be formed in various models for use in packaging either cans or bottles and contains a novel first cut-out formed in the dust flaps of the carton. The first cut-out is sized a predetermined length to provide a cut-out area so that the dust flaps can be revolved during the filling operation to clear the traveling flight bar used in the carton filling machine. A second pair of cut-outs may be formed in the dust flaps for similar purposes. A third and fourth pair of cut-outs may be formed in the dust flaps to minimize drag in combination with the first and second pair of cut-outs on one version of the carton. A fifth and sixth pair of cut-outs may be used with one of the models shown to aid in proper alignment of the carton end panels.

Claims2

Dependent claims

A paperboard sleeve-style beverage carton for use on a carton filling machine having traveling flight bars, comprising:

(a) a bottom panel;
(b) a pair of side panels, hingedly connected to opposite sides of the bottom panel;
(c) a first top panel and a second top panel hingedly connected to opposite sides of the side panels, the top panels being overlapped and adhesively secured together, and the top panels having handle means for lifting the carton;
(d) a pair of end panels hingedly connected to opposite ends of each of the side panels, each end panel having an upper and a lower cutout whereby the heights of the end panels are less than the heights of the side panels and the upper and lower edges of each end panel are spaced from the top and bottom panels respectively;
(e) a pair of bottom panel dust flaps hingedly connected to opposite ends of the bottom panel, each bottom panel dust flap having a first bottom panel dust flap cutout on one side and a second bottom panel dust flap cutout on the other side with the first bottom panel dust flap cutouts being larger than the second bottom panel dust flap cutouts whereby the widths of the bottom panel dust flaps are less than the width of the bottom panel, the side edges of the bottom panel dust flaps are spaced from the side panels and the dust flaps can be revolved to extend outwardly from the bottom panel during the filling operation;
(f) a pair of first top panel dust flaps hingedly connected to opposite ends of the first top panel, each first top panel dust flap having a cutout on a side adjacent the side panel, the cutouts being substantially the same size as the first bottom panel dust flap cutouts whereby the widths of the first top panel dust flaps are less than the width of the first top panel, the side edges of the first top panel dust flaps are spaced from the side panels and the first top panel dust flaps can be revolved to extend outwardly from the first top panel during the filling operation;
(g) a pair of second top panel dust flaps hingedly connected to opposite ends of the second top panel, each second top panel dust flap having a cutout on a side adjacent the side panel, the cutouts being substantially the same size as the second bottom panel dust flap cutouts whereby the widths of the second top panel dust flaps are less than the width of the second top panel and the side edges of the second top panel dust flaps are spaced from the side panels;
and
(h) relief means on the hinged connections between at least one of the first and second top panel dust flaps and the respective top panel to aid in the folding of the first and second top panel dust flaps.
