Abstract
Flexible filtering filling material consisting of pieces that are 100% open cell reticulated polyurethane foam. The pieces filter out the damp warm condition within the filling, haltering the proliferation of microorganisms, giving the product a more sanitary and longer life.
Claims9
A filler material of discrete randomly placed open celled reticulated polyurethane foam pieces for use in pillows adapted to support a person who applies pressure to the filler material, the filler material comprising a plurality of reticulated 100% open cell structured foam pieces having a reticulated structure and an elongated flattened shape having an outer surface defining open regions and the pieces are of a size from approximately 1/16 to ¼ inches thick by ⅛ to ¾ inch wide by 1 to 2 inches long, the cross sectional area having sufficient flex to allow the foam piece to flexibly bend under pressure applied by a portion of the person, the foam pieces having a yield strength sufficient to enable the foam pieces to repeatedly reposition back to their original shape after removal of pressure applied by a portion of the person, wherein the filler material is adapted to let air freely pass therethrough with no obstruction between the reticulated structure members from the center region of the filler material to the exterior portion of the filler material.
A pillow having a thin breathable lining between 0.005″ and 0.030″, filler material of discrete randomly placed open cell reticulated polyurethane foam pieces for use in pillows adapted to support a person who applies pressure to the filler material, the filler material comprising a plurality of reticulated 100% open cell structured foam pieces having a reticulated structure and an elongated flattened shape each having an outer surface defining open regions at a size from approximately 1/16 to ¼ inches thick by ⅛ to ¾ inch wide by 1 to 2 inches long, the cross sectional area having sufficient flex to allow the foam piece to flexibly bend under pressure applied by a portion of the person, the foam pieces having a yield strength sufficient to enable the foam pieces to repeatedly reposition back to their original shape after removal of pressure applied by a portion of the person, whereas the filler material is adapted to let air freely pass therethrough with no obstruction between the reticulated structure members from the center region of the filler material to the exterior portion of the filler material and the pillow is adapted to have a uniform engagement of the filler material to the lining when pressure from the person is placed thereon.
