IPC: B65D81/26
Filed: 1997-12-09
Abstract: A disposable safety bag for storage and transporting fluid containers filled with potentially hazardous liquids comprises a separate compartment for holding any spilled or leaking fluid to avoid exposure to handlers.  The safety bag is characterized by fluid impermeable exterior walls forming an interior chamber with a fluid tight closure.  The interior chamber is subdivided by at least one ply of one-way porous film forming a primary compartment and at least one secondary compartment for entrapping and retaining leaking hazardous liquids.
