Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 211 words
A funnel, for use on a container, said container having a circular upper surface, a container flange upwardly directed from the periphery of the upper surface, and a container lip extending radially from the upper edge of the container flange, comprising: a. a first circular aperture, defining a plane, and having an axis and a circumference, b. a second aperture of smaller area than said first aperture, and having a periphery and a geometric center, said second aperture being spaced from the plane of the first aperture and located so that its center is spaced from the axis of the first aperture, c. a elastomer plastic web connecting every point on the periphery of the second aperture to every point on the circumference of the first aperture, d. a first flange, concentric with the first aperture and extending longitudinally from the plane, and positioned to engage the inner surface of the container flange, e. a second flange, of large diameter than and concentric to the first flange, and extend longitudinally from the plane, f. a peripheral, inwardly-directed lip extending radially from the second flange, and positioned to engage the lower portion of the container lip thereby cooperating with the first flange to form a seal with the periphery of the container.
