Abstract
A clamshell container includes a bottom portion and a top portion. The bottom portion includes a bottom wall and a side wall attached to the bottom wall. The bottom wall and the side wall form a bottom recessed area. The top portion is connected with the bottom portion along a fold line. The top portion is configured to fold over at least part of the bottom portion at the fold line to form a storage area between the top portion and the bottom recessed area. The top portion and the bottom portion are constructed of a first layer and a second layer attached to the first layer by an insulating material. The insulating material includes micro-encapsulated particles to expand and provide thermal insulation.
Claims22
A clamshell container comprising:
- a bottom portion including a bottom wall and a side wall attached to the bottom wall, the bottom wall and the side wall forming a bottom recessed area;
- a top portion connected with the bottom portion along a fold line, the top portion configured to fold over at least part of the bottom portion at the fold line to form a storage area between the top portion and the bottom recessed area, the top portion and the bottom portion being constructed of a first layer and a second layer attached to the first layer to form an airgap therebetween;
- and
- expanded insulation that engages both the first layer and the second layer to adhere the first layer to the second layer, the expanded insulation disposed in a pattern within the air gap to define air channels, and the expanded insulation being formed from an insulating material including expandable microspheres having an activation temperature not exceeding 190° F., the expanded insulation including expanded, non-ruptured microspheres.
A clamshell container, comprising:
- a bottom portion comprising a plurality of walls forming a bottom recessed area;
- a top portion comprising a plurality of walls forming a top recessed area, the top portion connected to the bottom portion along a fold line, the top portion and the bottom portion comprised of a first layer and a second layer attached to the first layer to form an airgap therebetween;
- and
- expanded insulation that engages both the first layer and the second layer to adhere the first layer to the second layer and to create air gaps between the first layer and the second layer, the expanded insulation being formed from an insulating material including expandable microspheres having an activation temperature not exceeding 190° F., the expanded insulation including expanded, non-ruptured microspheres.
A clamshell container, comprising:
- a bottom portion comprising a plurality of walls forming a bottom recessed area;
- a top portion comprising a plurality of walls forming a top recessed area, the top portion connected to the bottom portion along a fold line, the top portion and the bottom portion comprised of a first layer and a second layer attached to the first layer to form an airgap therebetween;
- expanded insulation engaging both the first layer and the second layer to adhere the first layer to the second layer and to create air gaps between the first layer and the second layer, the expanded insulation being formed from an insulating material including expandable microspheres having an activation temperature not exceeding 190° F.;
- wherein the expanded insulation comprises expanded, non-ruptured microspheres when the second layer is permanently attached to the first layer.
