A paperboard sling extends between the first and second chocks comprising first and second ends joined to the first and second chocks, respectively.
Claims28
A releasable paperboard chock formed from a blank comprising a first section, a second section connected to the first section and a third section connected to the second section, the first section including a bottom panel and first and second outer side panels, the second section comprising a back panel and the third section comprising first and second inner side panels, the releasable paperboard chock comprising:
- a base defined by the bottom panel;
- a back wall defined by the back panel;
- and
- first and second side walls adjacent to the base and defined by the first and second outer side panels and the first and second inner side panels, wherein each of the first and second inner and outer side panels comprises an upper edge surface having at least a portion that is generally curved so as to conform to a curved surface of a roll to be secured.
A paperboard blank for use in forming a releasable paperboard chock comprising:
- a first section comprising a bottom panel and first and second outer side panels connected respectively to the bottom panel via score lines, wherein an outer edge surface of each of the first and second outer side panels comprises a generally curved portion;
- a second section comprising a back panel connected to the bottom panel by a score line;
- and
- a third section connected to the second section comprising first and second inner side panels, wherein an outer edge surface of each of the first and second inner side panels comprises a generally curved portion.
A releasable paperboard chock assembly comprising:
- a first paperboard chock comprising a first base, a first back wall, and first and second side walls adjacent to the base, wherein each of the first and second side walls comprises an upper edge surface, wherein the first back wall comprises a lower edge located near a support surface and an upper edge opposed to the lower edge;
- a second paperboard chock comprising a second base, a second back wall, and third and fourth side walls adjacent to the base, wherein each of the third and fourth side walls comprises an upper edge surface, wherein the first and second chocks are positioned such that the upper edge surfaces of the first and second side walls of the first chock are facing towards the upper edge surfaces of the third and fourth side walls of the second chock;
- and
- a paperboard sling extending between the first and second chocks comprising first and second outer ends joined to the first and second chocks, respectively, wherein the sling first end is joined to the first chock only at the first back wall of the first chock, wherein a roll may be positioned on the chock assembly such that the roll is located on the sling with the first and second chocks at least partially located under the sling and the roll to secure the roll in position and wherein the first chock can be removed to release the roll after separating a section of the sling from the first chock.
