Abstract
Air cell dunnage is disclosed which collapses for shipment and is constructed to be subsequently inflated for use. The air cell dunnage is a bubble sheet containing a multiplicity of gas cells and a base layer fused to the bubble layer. The bubble layer further includes conduits interconnecting selected groups of the selected cells and a common channel extending longitudinally on the sheet in fluid communication with each of the selected groups. The conduits provide access to selected groups of gas cells for collapsing and inflating the cells for shipment and use, respectively.
Claims12
A method of manufacturing collapsed air cell dunnage which can thereafter be inflated for use, comprising:
- producing a bubble sheet including a bubble layer having a multiplicity of bubbles protruding from its surface and a base layer connected thereto;
- flattening the bubble sheet to expel gas from the bubbles of the bubble sheet;
- and
- packaging the flattened bubble sheet for shipment.
A method of manufacturing collapsed air cell dunnage which can thereafter be inflated for use, comprising:
- producing a bubble sheet including a bubble layer with a base layer connected thereof, wherein the bubble sheet includes conduits interconnecting selected groups of bubbles and a common channel extending longitudinally on the sheet and in fluid communication with each of the groups through the conduits;
- and
- flattening the bubble sheet to expel gas from the bubbles of the bubble sheet.
A method of manufacturing air cell dunnage, comprising:
- producing a bubble sheet comprising a bubble layer having a multiplicity of bubbles protruding from its surface and a base layer connected thereto,
- flattening the bubble sheet to expel air from the bubbles,
- transporting the flattened bubble sheets, and
- thereafter expanding the bubbles in the bubble sheet.
A method of deflating air cell dunnage including a bubble sheet having a bubble layer and a base layer connected thereto and gas contained in the bubble layer as a result of forming the air cell dunnage, the bubble layer further including conduits interconnecting selected groups of bubbles in the bubble sheet, comprising:
- rotating rollers during movement of the bubble sheet, the rollers being oriented transverse to the conduits along the selected groups of bubbles and at an angle relative to the movement of the bubble sheet, thereby causing the gas to be expelled from the bubbles in each of the selected groups consecutively such that gas trapped in any of the bubbles during deflation is minimized.
