Collapsible tray and methods therefor

A method of collapsing a meal kit tray assembled from a single tray blank comprising a bottom panel, wherein:

• the bottom panel is configured to support a bag containing refrigerated items and a cold pack, the bottom panel defining an upper surface, a first end, a second end, a third end, and a fourth end;
• the single tray blank further comprises:
• a side panel extending outwardly from at least a portion of the second end of the bottom panel, the side panel joined to the bottom panel along a first fold line defining a joint between the bottom panel and the side panel, the side panel defining a first end, a second end, a third end, and a fourth end;
• a wing extending outwardly from the third end of the side panel, the wing joined to the side panel along a second fold line defining a joint between the side panel and the wing, the wing defining a front end, a rear end, a proximal end, and a free end;
• and
• an end panel extending from the first end of the bottom panel, the end panel joined to the bottom panel along a third fold line defining a joint between the bottom panel and the end panel, the end panel defining a first end, a second end, a third end, and a fourth end;
• wherein the end panel defines a corner located at an intersection of the first end of the end panel with the fourth end of the end panel;
• wherein a transverse fold line extends from the corner to the second end of the end panel, the transverse fold line subdividing the end panel into a primary section and a secondary section;
• wherein a reinforcement panel extending from the fourth end of the end panel, the reinforcement panel joined to the end panel along a fourth fold line defining a joint between the reinforcement panel and the end panel, the reinforcement panel defining a proximal end, a distal end, a top end, and a separable end joined to at least a portion of the first end of the side panel along a perforation line segment;
• wherein the side panel defines a side panel outer surface, wherein the reinforcement panel defines a reinforcement panel outer surface, and the single tray blank further comprises an adhesive region on the side panel outer surface proximate the first end of the side panel;
• and
• wherein the reinforcement panel is joined to the side panel due to contact between the reinforcement panel outer surface and the adhesive region;
• and
• the method comprises a step of causing the secondary section to be folded atop the primary section comprising a step of rotating the side panel inwardly toward the upper surface of the bottom panel to cause the reinforcement panel to push the end panel outwardly until the secondary section is folded inwardly about the transverse fold line onto the primary section.
