Abstract
A material for forming a carton for containing a plurality of articles. The material can comprise a plurality of layers comprising a first layer comprising a base and a second layer comprising an insulator. The first layer can be an exterior layer, and the second layer can be a interior layer. The layers of the plurality of layers can be respectively overlapped and attached to one another.
Claims33
A material for forming a carton for containing a plurality of articles, the material comprising:
- a plurality of layers comprising a first layer comprising a base comprised of paperboard or fiberboard, a second layer comprising an insulator, a third layer, and at least one layer of adhesive attaching the third layer to the second layer, the first layer being an exterior layer and the second layer being an interior layer disposed between the first layer and the third layer;
- the layers of the plurality of layers being respectively overlapped and attached to one another;
- and
- the insulator of the second layer is a spray adhesive, wherein the spray adhesive is in direct contact with the paperboard or fiberboard of the first layer, and the spray adhesive is in direct contact with the at least one layer of adhesive.
A material for forming a carton for containing a plurality of articles, the material comprising:
- a plurality of layers comprising at least a first layer, a second layer, and a third layer, the first layer, the second layer, and the third layer being respectively overlapped and attached to one another, the third layer attached to the second layer with at least one layer of adhesive;
- the first layer is an outer layer and comprises a substantially rigid base comprised of paperboard or fiberboard;
- the second layer is a middle layer and comprises an insulator, the insulator consisting of a spray adhesive, the spray adhesive being in direct contact with the paperboard or fiberboard of the first layer, and the spray adhesive being in direct contact with the at least one layer of adhesive;
- and
- the third layer is an inner layer and comprises a generally smooth interior surface for contacting at least one article of the plurality of articles in the carton formed from the material.
A method of forming a material for forming a carton for containing a plurality of articles, the method comprising:
- obtaining a base comprised of paperboard or fiberboard;
- forming an insulator comprising spraying a spray adhesive onto the base so that the insulator is the spray adhesive and the spray adhesive is in direct contact with the paperboard or fiberboard of the base, wherein the insulator and the base form respective layers that are overlapped and attached to one another, and the base is an exterior layer;
- and
- attaching an interior layer to the insulator with at least one layer of adhesive so that the insulator is disposed between the base and the interior layer and the spray adhesive is in direct contact with the at least one layer of adhesive.
