Abstract

An insulated bag includes a pair of opposing main panels; a pair of opposing side panels, each side panel attached to each main panel, the main panels and the side panels defining a bag cavity within the insulated bag; and a handle assembly, the handle assembly comprising a handle portion attached to a base portion; the main panels and the side panels defined in an insulated blank, the insulated blank comprising an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated between the first sheet and the second sheet, the first sheet attached in facing engagement with the second sheet to form a border, the border extending around a perimeter of the insulation batt, the base portion of the handle laminated within the border.

Claims

1. An insulated bag comprising:

a handle assembly, the handle assembly comprising a handle portion attached to a base portion, the base portion comprising a base strip, the base strip comprising a first strip and a second strip attached together in facing engagement, a bottom portion of the handle portion being laminated between the first strip and the second strip;

the main panels and the side panels defined in an insulated blank, the insulated blank comprising an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated between the first sheet and the second sheet, the first sheet attached in facing engagement with the second sheet to form a border, the border extending around a perimeter of the insulation batt, the base portion of the handle assembly being laminated within the border between the first sheet and the second sheet, the border defining at least one slit extending from the top end to the base strip, the at least one slit defined by the first sheet of the border, the handle portion extending outward from the border through the first sheet.

2. The insulated bag of claim 1, further comprising a bottom panel, wherein:

the bottom panel is disposed at the bottom end; and

a side seam extends from the bottom panel to the top end of the insulated bag.

3. The insulated bag of claim 2, wherein a one of the side panels comprises a pair of side subpanels joined together by the side seam.

4. The insulated bag of claim 2, wherein:

the insulated blank defines a centerline;

the centerline defines a first half and a second half of the insulated blank;

a first side border portion of the border is defined by the first half;

a second side border portion of the border is defined by the second half; and

the first side border portion is attached in facing engagement with the second side border portion to form the side seam.

5. The insulated bag of claim 4, wherein the first half is symmetrical to the second half across the centerline.

6. The insulated bag of claim 4, wherein the border is two-ply, and wherein the side seam is four-ply.

7. The insulated bag of claim 1, wherein:

an extended neck portion of the border extends around the bag opening; and

the extended neck portion is attached to both main panels.

8. The insulated bag of claim 1, wherein the insulated bag further comprises a corner ear and a bottom panel, wherein the corner ear is positioned between the bottom panel and a one of the pair of opposing side panels, and wherein the corner ear is folded downwards and attached to the bottom panel.

9. An insulated bag assembly comprising:

an insulated bag, the insulated bag comprising;

a pair of opposing main panels, the pair of opposing main panels defining a bag cavity within the insulated bag, the insulated bag defining a top end and a bottom end, and a bag opening to the bag cavity defined at the top end; and

a handle assembly, the handle assembly comprising a handle portion attached to a base portion, the base portion comprising a base strip, the base strip comprising a first strip and a second strip attached together in facing engagement, a bottom portion of the handle portion being laminated between the first strip and the second strip;

the pair of opposing main panels defined in an insulated blank, the insulated blank comprising an insulation batt, a first sheet, and a second sheet, the insulation batt encapsulated between the first sheet and the second sheet, the first sheet attached in facing engagement with the second sheet to form a border, the border extending around a perimeter of the insulation batt, the base portion of the handle assembly being laminated within the border between the first sheet and the second sheet, the border defining at least one slit extending from the top end to the base strip, the at least one slit defined by the first sheet of the border, and the handle portion extending outward from the border through the first sheet; and

an insulated panel, the insulated panel positioned within the bag cavity, the insulated panel comprising an insulation panel batt, a first panel sheet, and a second panel sheet, the insulation panel batt encapsulated between the first panel sheet and the second panel sheet, the first panel sheet attached in facing engagement with the second panel sheet to form a panel border, the panel border extending around a panel perimeter of the insulation panel batt, the panel border of the insulated panel forming a seal with the insulated bag.

10. The insulated bag assembly of claim 9, wherein the insulated panel partitions the bag cavity into a first compartment and a second compartment.

11. The insulated bag assembly of claim 9, wherein:

a first side subpanel is attached to a first main panel of the pair of main panels;

a second side subpanel is attached to a second main panel of the pair of main panels; and

the first side subpanel is attached to the second side subpanel by a side seam to form a side panel.

12. The insulated bag assembly of claim 11, wherein a first side portion of the border is attached in facing engagement with a second side portion of the border to form the side seam.

13. The insulated bag assembly of claim 9, wherein:

a portion of the border extending around the bag opening defines an extended neck; and

the bag opening is sealed by rolling opposing portions of the extended neck together to form a roll top seal.

14. The insulated bag assembly of claim 9, wherein:

the first sheet defines a first corner ear portion;

the second sheet defines a second corner ear portion;

the insulation batt defines a first cutout positioned to align with the first corner ear portion and the second corner ear portion;

the first corner ear portion is attached in facing engagement with the second corner ear portion to form a corner ear; and

the corner ear is uninsulated.

15. The insulated bag assembly of claim 14, wherein:

the insulated bag comprises a bottom panel attached to both of the opposing main panels; and

the corner ear is folded downwards and attached to the bottom panel.

16. A method for forming an insulated bag, the method comprising:

positioning an insulation batt between a first sheet and a second sheet;

attaching the first sheet and the second sheet in facing engagement to form a border, the border extending around a perimeter of the insulation batt, the border encapsulating the insulation batt and forming an insulated blank;

laminating a base portion of a handle assembly within the border, the base portion comprising a base strip, the base strip comprising a first strip and a second strip attached together in facing engagement, a bottom portion of a handle portion of the handle assembly being laminated between the first strip and the second strip;
