Bulk Packaging Container

Abstract

A dual tank bulk packaging container comprises an inner receptacle comprising a peripheral wall between opposite top and bottom walls to define a primary containment space. The inner receptacle comprises an outlet proximate a bottom end thereof. An outer shell comprises a peripheral sidewall connected to a formed bottom to define a secondary containment space having an upper opening sized to receive the inner receptacle. The outer shell includes integral legs for resting on a support surface. The peripheral sidewall is configured to support the inner receptacle in the secondary containment space. The outer shell comprises an outlet proximate a bottom end thereof wherein the inner receptacle outlet is aligned with the outer shell outlet incident to the inner receptacle being received in the outer shell. A seal is provided between the inner receptacle and the outer shell proximate the outlets thereof.
