Abstract
Abstract A tube-dispensable combination expanding pan-liner and hotpad for pans and the like, comprising a metal foil disc having the periphery folded inward, the disc folded inward over the inwardly folded periphery about a diameter of the disc to semi-disc configuration, and the semi-disc rolled into a coiled funnel configuration approximating the overall shape of a conical drinking cup, and dispensable in the same manner as a conical drinking cup from a tubular dispenser having an internal constriction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
The combination of a tube dispenser and a tube-dispensable expanding pan-liner comprising: an unfoldable metal foil disc having a diametral fold incorporated in a coiled-funnel configuration having both ends open, with said diametral fold portion forming the edge at the small end of the coiled-funnel configuration and the edges of the metal disc other than the diametral fold portion forming the edge at the large end of the coiled-funnel configuration; said coiled-funnel configuration large end engaging a constriction within said tube dispenser and being held therein by the springlike resiliency of the coil to deter passage of the pan-liner through said tube dispenser, and the interior of said coiled-funnel configuration being open to permit nesting storage of a plurality of said pan-liners above it within said tube dispenser.
Claim 2
Dependent Claim
128 words
The combination of a tube dispenser and a tube-dispensable expanding pan-liner comprising: an unfoldable metal foil disc having a diametral fold incorporated in a coiled-funnel configuration having both ends open, with said diametral fold portion forming the edge at the small end of the coiled-funnel configuration and the edges of the metal disc other than the diametral fold portion forming the edge at the large end of the coiled-funnel configuration; said coiled-funnel configuration large end engaging a constriction within said tube dispenser and being held therein by the springlike resiliency of the coil to deter passage of the pan-liner through said tube dispenser, and the interior of said coiled-funnel configuration being open to permit nesting storage of a plurality of said pan-liners above it within said tube dispenser.
Claim 3
Dependent Claim
