Abstract
A container including a container body with a pivotally mounted top lid utilizing a single generally planar elastomeric member forming a seal section releasably mounted to the undersurface of the lid and engageable with the rim of the container body peripherally thereabout, and a spring section integral with the seal section and extending from the lid into a receiving chamber on the container body adjacent the pivotal mounting of the lid, the spring section being resiliently compressed during the positioning thereof to provide a constant opening biasing force on the lid relative to the container body. An alternately positionable handle is removably mounted, at the option of the user, to either the front wall or the rear wall of the container body.
