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.
Claims25
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,
- wherein the cap members are present in a cap-cut sheet, with each cap member having a discrete set of cap-cuts therearound, with each cap-cut in each set defining a portion of an edge of a discrete cap member, with each cap member being integral with the cap-cut sheet, with a plurality of cap members extending outwardly from a portion of the cap-cut sheet between the cap members, with the size and arrangement of the cap members substantially corresponding with the size and arrangement of discrete sets of flap-cuts in the flap-cut sheet, with the outwardly extending cap members being affixed by directly bonding to the outwardly extending flap members of the flap-cut sheet,
- wherein the composite domes have a continuous spheroid shape.
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 that is 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 plurality of composite domes 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,
- wherein the cap members are present in a cap-cut sheet, with each cap member having a discrete set of cap-cuts therearound, with each cap-cut in each set defining a portion of an edge of a discrete cap member, with each cap member being integral with the cap-cut sheet, with a plurality of cap members extending outwardly from a portion of the cap-cut sheet between the cap members, with the size and arrangement of the cap members substantially corresponding with the size and arrangement of discrete sets of flap-cuts in the flap-cut sheet, with the outwardly extending cap members being affixed by directly bonding to the outwardly extending flap members of the flap-cut sheet,
- wherein the composite domes have a continuous spheroid shape.
