Abstract
A leak resistant tray and a method of forming the tray from a blank. The blank comprises a bottom panel, first and second side panels, and first and second end portions connected to peripheral edges of the bottom panel. Each end portion includes inner end panel structure having a lower end panel and an upper end panel. Each end portion further includes first and second intermediate panels connected to the first and second side panels, first and second outer end panels connected to respective first and second intermediate panels, and first and second triangular gusset panels, each gusset panel connected between one of the intermediate panels and the lower end panel. First and second gusset trough panels are connected to a respective one of the gusset panels and to a lower edge of one of the outer end panels.

A blank for making a leak resistant tray comprising:
- a bottom panel having a plurality of peripheral edges;
- first and second side panels connected to the bottom panel at opposing lateral peripheral edges and defining lower edges of the tray;
- first and second end portions located at opposing longitudinal ends of the blank, each end portion including:
- inner end panel structure connected to a longitudinal peripheral edge of the bottom panel, the inner end panel structure including a lower end panel and an upper end panel;
- first and second intermediate panels, each intermediate panel connected to a respective one of the first and second side panels and having an edge defining a lower edge of the tray;
- first and second outer end panels, each outer end panel connected to a respective one of the first and second intermediate panels and having an edge defining a lower edge of the tray;
- first and second triangular gusset panels, each gusset panel connected between one of the intermediate panels and the lower end panel;
- and
- first and second gusset trough panels, each gusset trough panel connected to one of the gusset panels and to the lower edge of one of the outer end panels.
A tray formed from a blank including a bottom panel having a plurality of peripheral edges, first and second side panels connected to the bottom panel at opposing lateral peripheral edges and folded upward relative to the bottom panel, first and second end portions located at opposing longitudinal ends of the blank, each end portion including:
- inner end panel structure connected to a longitudinal peripheral edge of the bottom panel, the inner end panel structure including a lower end panel;
- first and second intermediate panels, each intermediate panel connected to a respective one of the first and second side panels and extending upward from the bottom panel;
- first and second outer end panels, each outer end panel connected to a respective one of the first and second intermediate panels and extending generally perpendicular to the side panels;
- first and second triangular gusset panels, each gusset panel connected between one of the intermediate panels and the lower end panel and extending downward from the lower end panel;
- and
- first and second gusset trough panels, each gusset trough panel connected to one of the gusset panels and to the lower edge of one of the outer end panels and folded upward to overlapping relationship with a respective outer end panel.
A method of forming a tray from a blank comprising a bottom panel having a plurality of peripheral edges, first and second side panels connected to the bottom panel at opposing lateral peripheral edges, first and second end portions located at opposing longitudinal ends of the blank, each end portion including inner end panel structure connected to a longitudinal peripheral edge of the bottom panel, the inner end panel structure including a lower end panel, first and second intermediate panels connected to respective ones of the first and second side panels, first and second outer end panels connected to respective ones of the first and second intermediate panels, first and second triangular gusset panels between respective ones of the intermediate panels and the lower end panel, and first and second gusset trough panels, each gusset trough panel connected to one of the gusset panels and to the lower edge of one of the outer end panels, the method including forming an end portion of the tray comprising:
- folding the first gusset panel downward from the lower end panel while folding the first side panel upward relative to the bottom panel;
- folding the first intermediate panel upward at a connection with the first gusset panel while folding the first outer end panel upward at a connection with the first gusset trough panel;
- and
- folding the first outer end panel and the first gusset trough panel relative to the first intermediate panel about a generally vertical axis to position the first outer end panel and the first gusset trough panel generally perpendicular to the first side panel.
