US 5,244,281 A · Static controlled collapsible receptacle

Abstract

The present invention comprises a flexible, collapsible receptacle for handling flowable materials fabricated from an improved conductive woven metalized, anti-static fabric to more efficiently and effectively dissipate static electric build-up generated during the handling of flowable materials. In a first embodiment of the invention, a laminated metalized, anti-static fabric is utilized for fabricating all, or selected parts of the receptacle. In a second embodiment of the invention, all or part of the receptacle is formed from a sandwiched metalized and anti-static fabric. Parts of the receptacle not formed from either the laminated metalized, anti-static fabric or sandwiched metalized and anti-static fabric are fabricated from an anti-static fabric. Conductive anti-static lift straps are then added to the receptacle for support and to assist in static discharge. A conductive plastic liner is also inserted into the receptacle to further assist in the discharge of static build-up.
