Abstract
A thermally insulated container is disclosed. The container comprises an inner layer having a bottom portion with a bottom closure attached to the bottom portion. The container further comprises an outer layer wrapped around the inner layer. The container further comprises an insulating middle layer sandwiched between the inner layer and the outer layer. The middle layer has at least one aperture formed therein.
Claims (21)
1. ~A thermally insulated container comprising:
an inner layer having a bottom portion with a bottom closure attached to the bottom portion;
an outer layer wrapped around the inner layer; and an insulating middle layer sandwiched between the inner layer and the outer layer, the middle layer having at least one aperture formed therein.
an inner layer having a bottom portion with a bottom closure attached to the bottom portion;
an outer layer wrapped around the inner layer; and an insulating middle layer sandwiched between the inner layer and the outer layer, the middle layer having at least one aperture formed therein.
2. ~The container of claim 1, wherein the container is a cup.
3. ~The container of claim 1, wherein the at least one aperture is at least one slit.
4. ~The container of claim 1, wherein the at least one aperture is at least one hole extending completely through the sheet.
5. ~The container of claim 1, wherein the middle layer includes spaced grooves formed in a surface thereof, said spaced grooves running substantially from a top edge to a bottom edge of the middle layer.
6. ~The container of claim 1, further comprising a bottom blank attached to at least the inner layer to form a bottom of the container.
7. ~The container of claim 1, wherein the height of the middle layer is smaller than the height of the inner layer.
8. ~The container of claim 1, wherein the middle layer is formed from a sheet, the sheet being divided to form the middle layer and at least one other middle layer.
9. ~A method of making a thermally insulated container, the method comprising the acts of:
providing a bottom blank, an inner layer blank, and an outer layer blank;
providing a sheet adapted to be used as a middle layer blank;
dividing the sheet into at least a first middle layer blank and a second middle layer blank, at least one of the first middle layer blank and the second middle layer blank having an aperture formed thereon;
stacking the inner layer blank, the outer layer blank, and the first middle layer blank such that the first middle layer blank is sandwiched between the inner layer blank and the outer layer blank to form a layered arrangement;
wrapping the layered arrangement; and sealing opposing ends of the layered arrangement.
providing a bottom blank, an inner layer blank, and an outer layer blank;
providing a sheet adapted to be used as a middle layer blank;
dividing the sheet into at least a first middle layer blank and a second middle layer blank, at least one of the first middle layer blank and the second middle layer blank having an aperture formed thereon;
stacking the inner layer blank, the outer layer blank, and the first middle layer blank such that the first middle layer blank is sandwiched between the inner layer blank and the outer layer blank to form a layered arrangement;
wrapping the layered arrangement; and sealing opposing ends of the layered arrangement.
10. ~The method of claim 9 further comprising the acts of:
providing a second bottom blank, a second inner layer blank, and a second outer layer blank;
stacking the second inner layer blank, the second outer layer blank, and the second middle layer blank such that the second middle layer blank is sandwiched between the second inner layer blank and the second outer layer blank to form a second layered arrangement;
wrapping the second layered arrangement; and sealing opposing ends of the second layered arrangement.
providing a second bottom blank, a second inner layer blank, and a second outer layer blank;
stacking the second inner layer blank, the second outer layer blank, and the second middle layer blank such that the second middle layer blank is sandwiched between the second inner layer blank and the second outer layer blank to form a second layered arrangement;
wrapping the second layered arrangement; and sealing opposing ends of the second layered arrangement.
11. ~The method of claim 9, wherein the container is a cup.
12. ~The method of claim 11, further comprising the act of rolling a top portion of at least the inner layer radially outward to form a rim.
13. ~The method of claim 9, wherein the at least one aperture is at least one slit.
14. ~The method of claim 9, wherein the at least one aperture is at least one hole extending completely through the sheet.
15. ~The method of claim 9, wherein the sheet includes spaced grooves formed in a surface thereof, said spaced grooves running substantially from a top edge to a bottom edge of the sheet.
16. The method of claim 9, further comprising attaching a bottom blank to at least the inner layer to form a bottom of the container.
17. A method of making a thermally insulated container, the method comprising the acts of:
providing a sheet suitable for use as a middle layer, the sheet comprising an insulating sheet material;
dividing the sheet into at least a first middle layer and a second middle layer, wherein at least one of the first middle layer and the second middle layer includes an aperture being formed therein;
forming a first container, the first container including the first middle layer being sandwiched between a first inner layer and a first outer layer; and forming a second container, the second container including the second middle layer being sandwiched between a second inner layer and a second outer layer.
providing a sheet suitable for use as a middle layer, the sheet comprising an insulating sheet material;
dividing the sheet into at least a first middle layer and a second middle layer, wherein at least one of the first middle layer and the second middle layer includes an aperture being formed therein;
forming a first container, the first container including the first middle layer being sandwiched between a first inner layer and a first outer layer; and forming a second container, the second container including the second middle layer being sandwiched between a second inner layer and a second outer layer.
18. The method of claim 17, wherein the act of forming the first container further comprises:
stacking the first inner layer, the first outer layer, and the first middle layer such that the first middle layer is sandwiched between the first inner layer and the first outer layer to form a layered arrangement;
wrapping the layered arrangement; and sealing opposing ends of the layered arrangement.
stacking the first inner layer, the first outer layer, and the first middle layer such that the first middle layer is sandwiched between the first inner layer and the first outer layer to form a layered arrangement;
wrapping the layered arrangement; and sealing opposing ends of the layered arrangement.
19. The method of claim 17, wherein the act of forming the second container further comprises:
stacking the second inner layer, the second outer layer, and the second middle layer such that the second middle layer is sandwiched between the second inner layer and the second outer layer to form a layered arrangement;
wrapping the layered arrangement; and sealing opposing ends of the layered arrangement.
stacking the second inner layer, the second outer layer, and the second middle layer such that the second middle layer is sandwiched between the second inner layer and the second outer layer to form a layered arrangement;
wrapping the layered arrangement; and sealing opposing ends of the layered arrangement.
20. The method of claim 17, wherein the sheet is divided such that each of the first middle layer blank and the second layer blank includes more than one band.
21. The method of claim 17, wherein the sheet is generally rectangular.
