Abstract
The present invention provides a movable load bearing structure with a surface that includes antimicrobial agents capable of eliminating, preventing, retarding or minimizing the growth of microbes and also minimizing cross-contamination when the load bearing structure is being reused for cargoes that differ from a previously transported cargo, for example, different food types, such as poultry, fresh vegetables, and fresh fruit. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo.
Claims20
A loading bearing structure comprising:
- an expanded polymer core having a top side, a bottom side and a width having a thickness therebetween joining the top side and the bottom side;
- and
- at least one polymer sheet having a first side with outer edge portions, said first side of said polymeric sheet including the outer edge portions are combined with said bottom side, the width and at least a portion of said top side of said expanded polymeric core;
- wherein said outer edge portions of said first side of the polymeric sheet is sealed to portions of the expanded polymeric core by at least one sealing feature, said sealing feature is present at the peripheral of the outer edges of the polymeric sheet.
A loading bearing structure, comprising:
- an expanded polymer core with a top side, a bottom side and a width having a thickness therebetween joining the top side and the bottom side;
- a first polymer sheet having a first side and a second side, with outer edges, said first side and its outer edges are combined with said bottom side and at least part of said thickness of said width of said expanded polymer core;
- and
- a second polymer sheet having a first side and a second side, with outer edges, said second side and its outer edges are combined with said expanded polymer core on said top side and at least part of the thickness of the width of said expanded polymer core, forming an overlap between said outer edges of said first sheet and said outer edges of said second sheet about the width, said overlap having an outer edge;
- wherein only the peripheral of said overlapped outer edges between the first and second the polymeric sheets are sealed by at least one sealing feature for minimizing imperfections in the combining of the polymeric sheet with the core at the outer edges of the overlapped area.
A loading bearing structure comprising:
- an expanded polymer core having a top side, a bottom side and a width having a thickness therebetween joining the top side and the bottom side;
- and
- at least one polymer sheet having a first side with outer edge portions, said first side of said polymeric sheet including the outer edge portions are combined with said bottom side, the width and at least a portion of said top side of said expanded core, creating an interface between said polymer sheet and said expanded polymer core;
- wherein the interface at the outer edges of said first side of the polymeric sheet and said expanded polymer core includes at least one sealing feature, said sealing feature is present at the peripheral of the outer edges of the polymeric sheet only for a small portion of said outer edges.
