Abstract

A method for assembling an insulated bag includes folding a first main panel of a pair of opposing main panels relative to a first side panel of a pair of opposing side panels about a main crease line, the main panels, the side panels, and the main crease line defined in an insulated blank, the insulated blank including an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated in a blank cavity defined between the first sheet and the second sheet, a blank border extending around a perimeter of the insulated blank, the insulated blank defining a first end and a second end; attaching the first end to the second end; and forming a bottom panel of the insulated bag by folding a portion of the bottom panel relative to the main panel about a bottom crease line.

First claim

That which is claimed is:

1. A method for assembling an insulated bag comprising:
folding a first main panel of a pair of opposing main panels relative to a first side panel of a pair of opposing side panels about a main crease line, the main panels, the side panels, and the main crease line defined in an insulated blank, the insulated blank comprising an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated in a blank cavity defined between the first sheet and the second sheet, a blank border extending around a perimeter of the insulated blank, the blank border defined by a perimeter portion of the first sheet being in facing engagement with a perimeter portion of the second sheet, the blank border encompassing the blank cavity and defining an insulated portion of the insulated blank, the insulated blank defining a first end and a second end, the first end disposed opposite from the second end;
attaching the first end to the second end;
forming a bottom panel of the insulated bag by folding a portion of the bottom panel relative to the main panel about a bottom crease line, the bottom panel and the bottom crease line further defined by the insulated blank;
folding a wing about a base wing crease line towards the first side panel, the base wing crease line defined at an intersection of the wing and the first side panel; and
attaching the wing to the first side panel.

2. The method of claim 1 , wherein attaching the first end to the second end forms a bag body, wherein the bag body is defined by the main panels and the side panels, and wherein the bag body defines a rectangular cross-section.

3. The method of claim 1 , wherein the bottom panel comprises a pair of bottom subpanels, wherein each bottom subpanel is attached to a different one of the main panels, and wherein forming the bottom panel further comprises attaching a first bottom subpanel of the pair of bottom subpanels to a second bottom subpanel of the pair of bottom subpanels.

4. The method of claim 1 , wherein attaching the first end to the second end further comprises forming a main seam between a one of the main panels and a one of the side panels.

5. The method of claim 1 , wherein:
the bottom panel comprises four bottom flaps;
each of a first pair of the four bottom flaps is attached to a different one of the side panels;
each of a second pair of the four bottom flaps is attached to a different one of the main panels; and
forming the bottom panel further comprises overlapping a first bottom flap of the first pair of bottom flaps with a first bottom flap of the second pair of bottom flaps.

6. The method of claim 1 , wherein forming the bottom panel of the insulated bag comprises forming a bottom seam by attaching a first portion of a bottom border to a second portion of the bottom border, the blank border comprising the bottom border.

7. The method of claim 6 , wherein forming the bottom seam comprises attaching a first bottom subpanel to a second bottom subpanel, the first bottom subpanel defining the first portion of the bottom border, the second bottom subpanel defining the second portion of the bottom border.

8. The method of claim 7 , wherein attaching the first bottom subpanel to the second bottom subpanel comprises folding the first bottom subpanel relative to the first main panel, the first bottom subpanel attached to the first main panel.

9. The method of claim 1 , further comprising sealing a bag opening of the insulated bag, the bag opening defined opposite from the bottom panel.

10. The method of claim 9 , wherein sealing the bag opening comprises inserting an insulated panel into the bag opening.

11. The method of claim 10 , further comprising positioning a panel beveled edge of the insulated panel against a bag beveled edge of the insulated bag.

12. The method of claim 10 , further comprising contacting a panel border of the insulated panel with an inner surface defined by the first sheet, the inner surface defining a bag cavity within the insulated bag, the bag cavity extending inwards into the insulated bag from the bag opening towards the bottom panel.

13. The method of claim 9 , wherein sealing the bag opening comprises rolling an uninsulated bag lip to form a seal, the uninsulated bag lip defined by the blank border, the blank border extending around the bag opening.

14. The method of claim 9 , wherein sealing the bag opening comprises attaching opposing portions of an uninsulated bag lip together with an adhesive strip to form a seal, the uninsulated bag lip defined by the blank border, the blank border extending around the bag opening.
