  • Container with supplemental opening for extracting contents
    Patent number: 4762241
    Abstract: A container especially for use with viscous substances has both a primary opening and a supplemental opening. The primary opening is at an upper point in the container, whereby contents are extracted due to gravity, when tilting the container. A supplemental opening with removable closure is provided at a lowermost point in the container, for also extracting contents under gravity feed. The supplemental opening is preferably located at the end of a slope, causing material in the container to accumulate over the supplemental opening. Particular removable closures include plugs, tethered plugs and frangible panels.
