Patent ID: 8360642

Claim:
A ventilated bulk bag, comprising: a ventilated bag body having a bottom panel and side walls to define a cavity for receiving bulk articles; a top panel that attaches to the bag body, the top panel formed of a fabric of first yarns in a first direction and second yarns in a second direction traverse to the first direction, the first yarns having a first cross-sectional shape and the second yarns having a second cross-sectional shape different from that of the first yarns, the first yarns and the second yarns interwoven whereby the fabric defines gaps adjacent respective crossings of the interwoven first yarns and second yarns, which gaps are apparent when viewed from a 45 degree angle relative to a plan view of the fabric, for keeping dust landing thereon from going though the gaps but allowing the top panel to ventilate air through the gaps from the cavity; a discharge spout attached to the bottom panel; and a top spout attached to the top panel, whereby air, being ventilated into the cavity through the ventilated bag body, ventilates from the cavity through the gaps in the fabric of the top panel while the fabric keeps dust that lands on the top panel from going through into the cavity.
