Abstract

A tray blank includes a bottom panel defining a first end, a second end, a third end, and a fourth end; a side panel extending outwardly from the third end of the bottom panel, the side panel joined to the bottom panel along a first fold line, the side panel defining a first end, a second end, a third end, and a fourth end; a wing extending outwardly from the side panel, the wing joined to the side panel along a second fold line; and an end panel extending from the bottom panel, the end panel joined to the bottom panel along a third fold line; wherein at least one transverse fold line extends across the end panel and subdivides the end panel into a primary section and at least one secondary section.

First claim

That which is claimed is:

1. A tray blank, comprising:
a bottom panel defining a first end, a second end, a third end, and a fourth end, the bottom panel configured to support a bottom of a bag comprising a portion of a meal kit;
a side panel extending outwardly from at least a portion of the third 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 at least one transverse fold line extends across the end panel, the at least one transverse fold line subdividing the end panel into a primary section and at least one secondary section, the at least one transverse fold line configured to permit a folding of the at least one secondary section atop the primary section when a meal kit tray formed from the tray blank is changed from an assembled state to a collapsed state, and
wherein the first fold line is interrupted by at least one perforation line segment defining a standoff extending laterally from the first fold line and terminating in a standoff edge, each standoff configured to separate from the side panel as the side panel is rotated upwardly about the first fold line during assembly of the tray blank into the meal kit tray.

2. The tray blank of claim 1 , wherein the at least one transverse fold line extends to the second end of the end panel from an intersection of two adjacent ends of the end panel.

3. The tray blank of claim 2 , wherein:
the end panel defines a first corner located at an intersection of the first end of the end panel with the third end of the end panel;
the end panel defines a second corner located at an intersection of the first end of the end panel with the fourth end of the end panel; and
the at least one transverse fold line comprises a first transverse fold line and a second transverse fold line, the first transverse fold line extending from the first corner to the second end of the end panel, and the second transverse fold line extending from the second corner to the second end of the end panel.

4. The tray blank of claim 1 , wherein the side panel is a first side panel and the wing is a first wing, and wherein the tray blank further comprises:
a second side panel extending outwardly from at least a portion of the fourth end of the bottom panel, the second side panel joined to the bottom panel along a fourth fold line defining a joint between the bottom panel and the second side panel, the second side panel defining a first end, a second end, a third end, and a fourth end; and
a second wing extending outwardly from the fourth end of the second side panel, the second wing joined to the second side panel along a fifth fold line defining a joint between the second side panel and the second wing, the second wing defining a front end, a rear end, a proximal end, and a free end.

5. The tray blank of claim 4 , wherein at least one portion of the free end of the first wing and at least one portion of the free end of the second wing both define a chamfered portion, each chamfered portion configured to facilitate insertion of the meal kit tray into an outer box.

6. The tray blank of claim 1 , wherein the tray blank further comprises 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.

7. The tray blank of claim 6 , wherein at least a portion of the perforation line segment outlines a front tab extending forward from the first end of the side panel, the perforation line segment configured to facilitate separation of the reinforcement panel from the side panel when the tray blank is assembled into the meal kit tray, so as to form the front tab when the reinforcement panel is separated from the side panel, the front tab defining a leading edge formed from panel separation along the perforation line segment, the leading edge configured to engage a front inside wall of a front end of an outer box when the meal kit tray is inserted into the outer box.

8. The tray blank of claim 7 , wherein the end panel is a front end panel, the reinforcement panel is a first reinforcement panel, the perforation line segment is a first perforation line segment, and the leading edge is a front leading edge, and further comprising:
a rear end panel extending from the second end of the bottom panel, the rear end panel joined to the bottom panel along a fifth fold line defining a joint between the bottom panel and the rear end panel, the rear end panel defining a first end, a second end, a third end, and a fourth end; and
a second reinforcement panel extending from the third end of the rear end panel, the second reinforcement panel joined to the end panel along a sixth fold line defining a joint between the second reinforcement panel and the rear end panel, the second reinforcement panel defining a proximal end, a distal end, a top end, and a separable end joined to at least a portion of the second end of the side panel along a second perforation line segment;
wherein at least a portion of the second perforation line segment outlines a rear tab extending rearwardly from the second end of the side panel, the second perforation line segment configured to facilitate separating the second reinforcement panel from the side panel when the tray blank is assembled into the meal kit tray, so as to form the rear tab when the second reinforcement panel is separated from the side panel, the rear tab defining a rear leading edge along the second perforation line segment, the rear leading edge configured to engage a rear inside wall of a rear end of the outer box when the meal kit tray is inserted into the outer box.

9. The tray blank of claim 7 , wherein the side panel defines a side panel outer surface, wherein the reinforcement panel defines a reinforcement panel outer surface, and further comprising an adhesive region on the side panel outer surface proximate the first end of the side panel.

10. A tray blank, comprising:
a bottom panel defining a first end, a second end, a third end, and a fourth end, the bottom panel configured to support a bottom of a bag comprising a portion of a meal kit;
a side panel extending outwardly from at least a portion of the third 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;
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 be
