Abstract

A container is described having a series of bottom panels and a center divider. The center divider divides the container into compartments. Extended outer end panels are provided at the end edges of one compartment, and unextended outer end panels are provided at the end edges of an adjacent compartment. The unextended end panels have inner end panels attached to their outermost edges. Each of the extended outer end panels includes an extension portion. As assembled, these extension portions are sandwiched between their respective unextended outer end panel and its inner end panel. Various embodiments are presented, including one in which minor end flaps are used at the end edges of a center divider panel and inner end panels are attached to the outer edges of the extended end panels. As assembled, the minor end panels are sandwiched between their respective extended outer end panel and its inner end panel.

Dependent claims

A container blank comprising:

(a) a first bottom panel, a first center panel, a second center panel, and a second bottom panel;
these panels being hingedly connected to one another in series and each panel including opposed end edges;
(b) a first extended outer end panel hingedly connected to an end edge of the first bottom panel;
a second extended outer end panel hingedly connected to the other end edge of the first bottom panel;
the first extended outer end panel, the first bottom panel, and the second extended outer end panel thus being hingedly connected in series;
the first and second extended outer end panels each having a portion adjacent the bottom panel and an extension portion adjacent, though not connected to, the edge of the first center panel;
(c) a first unextended outer end panel hingedly connected to an end edge of the second bottom panel;
a third inner end panel hingedly connected to an outer edge of the first unextended outer end panel;
a second unextended outer end panel hingedly connected to the other end edge of the second bottom panel;
a fourth inner end panel hingedly connected to an outer edge of the second unextended outer end panel;
the third inner end panel, the first unextended outer end panel, the second bottom panel, the second unextended outer end panel, and the fourth inner end panel thus being hingedly connected in series;
wherein, as assembled, the first and second center panels are folded upward onto one another to form a center divide, thus causing the first and second extension portions to move adjacent and inward of the first and second unextended outer end panels, respectively;
the third and fourth inner end panels being folded inward and held therein;
the first extension portion being sandwiched between the first unextended outer end panel and the third inner end panel;
the second extension portion being sandwiched between the second unextended outer end panel and the fourth inner end panel.
