发明名称 Cup Rim Unroller
摘要 A tool for unfurling a rolled rim of a paperboard cup is disclosed. The tool comprises a rigid elongated member having a front side, a back side, and, preferably, four peripheral edges. One portion of the elongated member is rolled into a semi-spiral hook which is generally spiraled about a hook axis which is orthogonal to-but preferably does not intersect-a longitudinal axis of the elongated member. The hook axis is slightly curved to match a curvature of the rolled rim of the paperboard cup. An aperture is included through the elongated member at a lower end thereof. In use, the tool is grasped by a hand of a user, and the hook is inserted under the rolled rim of the paperboard cup. The tool is then pulled upward away from the cup to unfurl the rolled rim. The tool facilitates the unrolling of the rolled rim of the paperboard cup to reveal any writing or markings previously hidden within the rolled rim.
