Abstract
A wood cleated corrugated container having a load bearing, protective insert of corrugated board with a pair of rigid support members supported by a plurality of coplanar support points along a plane defining a boundary of, or dividing, the container. The corrugated container includes a wood pallet base having sockets which receive the lower ends of the vertical cleats to resist dislodgement of the cleats from the pallet during handling, shipment and storage.
Claims8
A wood reinforced corrugated container, comprising:
- a pallet for supporting an article to be packed;
- a corrugated paperboard body which attaches at a bottom end to the pallet, comprising a blank of corrugated paperboard scored for folding to provide a two opposing side walls and two opposing end walls, a plurality of vertically disposed spaced apart cleats attached to the two side walls, and a plurality of top flaps each joined along a respective second score line to a separate one of the walls and foldable normal to the wall to close the container;
- a first rigid member disposed normal between the side walls and supported at its longitudinal ends by one of the cleats on each of the side walls;
- a second rigid member disposed normal between the side walls and supported at its longitudinal ends by one of the other cleats on each of the side walls;
- and
- a sheet of semi-rigid material attached to an upper surface of each of the first and second rigid members;
- a third rigid member attached to the top flap of one of the end walls and disposed parallel to the respective second score line,
- wherein the longitudinal ends of the third rigid member contacts one of the other cleats on each of the side walls for support when the top flap is folded to partially close the container.
A protective member, sized for inserting into an open end of a wood reinforced corrugated paperboard container comprising a blank of corrugated paperboard scored for folding to provide a pair of side walls and a pair of end walls, at least one pair of vertically disposed end cleats with one end cleat attached to each of the side walls and both adjacent the same end wall, and a pair of vertically disposed middle cleats with one middle cleat attached to each of the side walls between the end walls, comprising:
- a planar sheet having four sides;
- a pair of side flanges, one side flange extending outwardly from each of two opposing sides of the sheet;
- an end flange extending outwardly from a third side of the sheet;
- each of the side flanges and the end flange foldable along a respective score line to a position normal to the sheet, with no flange on a fourth side of the sheet;
- a first support member attached to a lower surface of the sheet parallel to and near the score line for the end flange and extending between the two opposing sides for supporting by an upper end of each of the end cleats;
- and
- a second support member attached to the lower surface of the sheet parallel to and spaced apart from the first support member and extending between the two opposing sides for supporting by an upper end of each of the middle cleats,
- wherein the article in the container is protected by inserting the sheet, with the side flanges and the end flanges folded normal to the sheet, into the open end of the container to bring the first and the second support members into contact with the respective end and middle cleats thereby partially closing the container.
A wood reinforced corrugated paperboard container, comprising:
- a pallet for supporting an article in the container;
- a paperboard body which attaches at a bottom end to the pallet, comprising a blank of corrugated paperboard scored for folding to provide a pair of side walls and a pair of end walls, two vertically disposed end cleats, one end cleat attached to each of the side walls adjacent the same end wall, and a vertically disposed middle cleat attached to each of the side walls between the end walls;
- a planar sheet sized for inserting into an open end of the corrugated paperboard body and including:
- a side flange extending outwardly from each of two opposing sides of the sheet;
- an end flange extending outwardly from a third side of the sheet;
- each of the side flanges and the end flange foldable along a respective score line to a position normal to the sheet for disposing firmly against a respective wall of the paperboard body with no flange on a fourth side of the sheet;
- a first support member attached to a lower surface of the sheet parallel to and near the score line for the end flange and extending between the two opposing edges of the sheet for supporting by an upper end of each of the end cleats adjacent one of the end walls;
- and
- a second support member attached to the lower surface of the sheet parallel to and spaced apart from the first support member and extending between the two opposing edges of the sheet for supporting by an upper end of each of the middle cleats,
- whereby the article in the container is protected by inserting the sheet, with the side flanges and the end flanges folded normal to the sheet, into the open end of the container to bring the support members into contact with the respective end and middle cleats.
