Disposable insulated container with microflute structure

A method of making a disposable, insulated container comprising,

• aligning an inner container structure in a position to receive an outer insulating wrap,
• said inner container structure having an upper end portion providing an open top, a lower end portion providing a closed bottom, and a generally conically extending side wall portion providing a closed side wall between the open top and the closed bottom
• forming an outer insulating wrap with dimensions and a configuration to enable the outer insulating wrap to be assembled onto said side wall portion of the inner container structure with the wrap extending both around and up and down the outer side wall of said side wall portion for enabling the container to be held comfortably in the hand of a user when the container is filled with a liquid having temperatures up to or near the boiling point of water,
• said outer insulating wrap comprising a microflute laminated structure having:
• (a) a first corrugated laminate of microflute corrugations which are aligned so that the parallel extending ridges and depressions of the microflute corrugations are disposed substantially circumferentially around the side wall portion of the inner container structure, and
• (b) a second, outer sheet laminate of thin flexible paper extending on the outer side of the outer insulating wrap means and presenting a substantially smooth outer surface for engagement by the hand of a user of the container, and
• predisposing the outer insulating wrap to around said side wall portion prior to assembly of the outer insulating wrap on the inner container structure by forming the outer insulating wrap with an inwardly curved configuration prior to assembling the outer insulating wrap with the inner container structure
• applying an adhesive to certain spots on the inside surface of the outer insulating wrap,
• wrapping the outer insulating wrap into continuous, substantially uniform engagement with said side wall portion,
• adhering the outer insulating wrap to said side wall portion of the inner container structure, and
• wherein the size of the microflute corrugations, the generally circumferentially extending orientation of the microflute corrugations, and the thin thickness of the outer paper sheet laminate and the predisposing of the outer insulating wrap to wrap about said side wall portion enable the outer insulating wrap to be wrapped and maintained in continuous, substantially uniform engagement with said side wall portion without breaking or collapsing of the corrugations.
