Abstract
A thermal pack comprising one or more sacks, a body of thermal material enclosed in the sacks, and first and a second sack edge joined to form a seam line wherein the first edge and the second edge have intersecting directions with an angle that is less than 180 degrees whereby the one or more sacks conforms to a three-dimensional surface.
Claims20
A method of making a thermal pack, which comprises
- a. assessing a three-dimensional surface;
- b. flattening the assessed three-dimensional surface into a two-dimensional representation of the three-dimensional surface;
- c. forming a first pliable sheet and second pliable sheet into the form of the two-dimensional representation;
- d. forming one or more sacks by aligning and joining the first pliable sheet with and to the second pliable sheet;
- e. forming a plurality of elongated joint lines joining internal portions of the one or more sacks within the thermal pack, the plurality of elongated joint lines forming a tessellated plurality of hexagonal shaped thermal material cells;
- the hexagonal shaped thermal material cells having six faces wherein a first face joins a second face forming a first obtuse angle section, the second face joins a third face forming a second obtuse angled section, the third face joins a fourth face forming a third obtuse angled section, the fourth face joins a fifth face forming a fourth obtuse angled section, the fifth face joins the a sixth face forming a fifth obtuse angled section, the sixth face joins the first face forming a sixth obtuse angled section;
- the hexagonal shaped thermal material cells further having a first gap disposed in the first face, a second gap is disposed in the second face, a third gap is disposed in the fourth face, and a fourth gap is disposed in the fifth face;
- the hexagonal shaped thermal cells having an upper thermal material retaining portion comprising the first obtuse angled section, the second face, and the second obtuse angled section configured to deflect thermal material flow towards a thermal cell center;
- the hexagonal shaped thermal material cells further having a first lateral thermal material retaining portion comprising the sixth obtuse angled section and a second lateral thermal material retaining portion comprising the third obtuse angled section, the first and second lateral thermal material retaining portions configured to deflect thermal material flow towards the thermal cell center;
- and
- the hexagonal shaped thermal cells having an lower thermal material retaining portion comprising the fourth obtuse angled section, the fifth face, and the fifth obtuse angled section configured to retain thermal material flowing into the hexagonal shaped thermal cells and deflect excess thermal material flow towards the thermal cell center;
- f. filling the one or more sacks with the thermal material;
- and
- g. enclosing the thermal material within the one or more sacks.
