Claims21
A tray of paperboard material made from an integral, one-piece blank, comprising:
- a floor having a midportion formed of at least two layers folded against one another to form an upstanding divider wall, integrally formed with the floor and dividing the floor into two portions;
- front and rear walls upwardly extending from opposite ends of the floor;
- opposed sidewall panels between the front and rear walls, upwardly extending from the floor, above the front and rear walls;
- vertical beam members formed of at least two layers integrally formed with the sidewall panels and folded against one another with a fold line extending upwardly from the floor so as to outwardly extend from the sidewall panels toward one another and cooperating with the sidewall panels to form sidewalls of generally T-shaped cross section, the folded portions extending upwardly from the floor along the sidewall panels;
- and
- the vertical beam members located at opposing ends of the divider wall.
A container assembly comprising:
- a tray of paperboard material made from an integral, one-piece blank, including a floor having a midportion formed of at least two layers folded against one another to form an upstanding divider wall, integrally formed with the floor and dividing the floor into two portions, front and rear walls upwardly extending from opposite ends of the floor, opposed sidewall panels between the front and rear walls which extend upwardly from the floor above the front and rear walls, vertical beam members integrally formed of at least two layers integrally formed with the sidewall panels and folded against one another with a fold line extending upwardly from the floor so as to outwardly extend from the sidewall panels toward one another and cooperating with the sidewall panels to form sidewalls of generally T-shaped cross section, the folded portions extending upwardly from the floor along the sidewall panels, and the vertical beam members located at opposing ends of the divider wall;
- the sidewall panels and vertical beams having respective upper ends;
- and
- a cover of paperboard material made from an integral, one-piece blank, including a first wall adjacent the front wall of the tray and a second wall adjacent the rear wall of the tray, and a top wall adjacent the upper ends of the sidewall panels and vertical beams.
A blank made from an integral, single piece of paperboard material which is folded to form a tray including a floor, front and rear walls upwardly extending from opposite ends of the floor, opposed sidewall panels between the front and rear walls which extend upwardly from the floor above the front and rear walls, and vertical beam members extending from the sidewall panels toward one another and cooperating with the sidewall panels to form sidewalls of generally T-shaped cross section, the blank comprising:
- two outer columns comprising mirror images of one another;
- a central column between the two outer columns;
- the central column comprising a serial succession of at least one front panel, a first floor panel, a first center divider panel, a second divider panel, a second floor panel and at least one rear panel;
- the outer columns each comprising a serial succession of a forwardly facing panel, a first sidewall panel, a first vertical beam panel, a second vertical beam panel, a second sidewall panel and a rearwardly facing panel;
- the first and the second divider panels joined together by a first fold line, and the first and the vertical beam panels joined together by a second and a third fold line, respectively, lying on opposite ends of the first fold line in generally colinear relationship therewith;
- and
- the two outer columns joined to the central column by respective fold lines so that the first and second sidewall panels are connected to the first and second floor panels by the fold lines.
A tray of paperboard material made from an integral, one-piece blank, comprising:
- a floor;
- front and rear walls upwardly extending from opposite ends of the floor;
- opposed sidewall panels between the front and rear walls, upwardly extending from the floor, above the front and rear walls;
- vertical beam members extending from the sidewall panels toward one another and cooperating with the sidewall panels to form sidewalls of generally T-shaped cross section;
- the vertical beam members comprising outwardly folded portions of paperboard material forming the sidewall panels;
- and
- the floor having a midportion folded to form an upstanding divider wall, dividing the floor into two portions, with the midportion comprising overlapping panels adhesively bonded to one another.
A container assembly comprising:
- a tray of paperboard material made from an integral, one-piece blank, including a floor, front and rear walls upwardly extending from opposite ends of the floor, opposed sidewall panels between the front and rear walls which extend upwardly from the floor above the front and rear walls, and vertical beam members extending from the sidewall panels toward one another and cooperating with the sidewall panels to form sidewalls of generally T-shaped cross section;
- the sidewall panels and vertical beams having respective upper ends;
- a cover of paperboard material made from an integral, one-piece blank, including a first wall adjacent the front wall of the tray and a second wall adjacent the rear wall of the tray, and a top wall adjacent the upper ends of the sidewall panels and vertical beams;
- the vertical beam members comprising outwardly folded portions of paperboard material forming the sidewall panels;
- and
- the floor having a midportion folded to form an upstanding divider wall, dividing the floor into two portions, with the midportion comprising overlapping panels adhesively bonded to one another.
