Abstract
A cushioning article comprises a flap-cut sheet with a plurality of discrete sets of flaps, with each discrete set of flaps having a plurality of flaps extending outward from the sheet. A plurality of the outwardly extending flaps of each discrete set of flaps are affixed to a discrete cap member, resulting in a composite dome sheet having a plurality of composite domes extending from the flap-cut sheet. A cushioning and thermal protection packaging article for packaging a thermally-sensitive product utilizes a plurality of the layers of the composite dome sheet with each layer separated by a separating sheet. Both the composite dome sheet and the separating sheet can be made of paper.

A cushioning article comprising a composite dome sheet which comprises a flap-cut sheet having a plurality of discrete sets of intersecting flap-cuts therein, with each set of intersecting flap-cuts providing a discrete set of flap members integral with the flap-cut sheet, with a plurality of individual flaps of each set extending outwardly from a portion of the flap-cut sheet that is between the sets of flap-cuts, with at least two of the outwardly extending flaps of each discrete set being affixed to a discrete cap member to provide a plurality of composite domes extending from the flap-cut sheet.
A cushioning and thermal protection packaging article for packaging a thermally-sensitive product, the packaging article comprising:
- (A) a plurality of composite dome sheets comprising a plurality of layers of at least one flap-cut sheet, the at least one flap-cut sheet having a plurality of discrete sets of intersecting flap-cuts therein, with each set of intersecting flap-cuts providing a discrete set of flap members integral with the flap-cut sheet, with a plurality of individual flaps of each set extending outwardly from a portion of the flap-cut sheet between the sets of flap-cuts, with the plurality of the outwardly extending flaps of each discrete set of flaps being affixed to a discrete cap member to provide a composite dome extending from the portion of the flap-cut sheet between the flaps;
- and
- (B) a separating sheet between each of the layers of the at least one flap-cut sheet comprising the composite domes.
