Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 134 words
Heated dispensing apparatus comprising a base member having a substantially planar upper surface; a plurality of protrusions formed as an integral part of said surface and extending above the plane thereof, each of said protrusions defining a generally horizontal, unbroken, aplanar support surface having a circular periphery; means inbedded in said base member and disposed directly below said protrusions for exclusively heating the same over substantially the entire exposed surface area thereof; and at least one unitary, resilient, cylindrical container removably disposed directly atop said base member for heating fluid within said container, said container having a diameter substantially equal to the diameter of said at least one protrusion and having ar recessed bottom conforming to said aplanar support surface for direct heat transfer contact therewith over the entire bottom surface of said container.
Claim 2
Dependent Claim 134 words
Heated dispensing apparatus comprising a base member having a substantially planar upper surface; a plurality of protrusions formed as an integral part of said surface and extending above the plane thereof, each of said protrusions defining a generally horizontal, unbroken, aplanar support surface having a circular periphery; means inbedded in said base member and disposed directly below said protrusions for exclusively heating the same over substantially the entire exposed surface area thereof; and at least one unitary, resilient, cylindrical container removably disposed directly atop said base member for heating fluid within said container, said container having a diameter substantially equal to the diameter of said at least one protrusion and having ar recessed bottom conforming to said aplanar support surface for direct heat transfer contact therewith over the entire bottom surface of said container.
Claim 3
Dependent Claim 12 words
The invention as recited in claim 1 wherein said protrusions are conical.
Claim 4
Dependent Claim 12 words
The invention as recited in claim 1 wherein said protrusions are curvilinear.
Claim 5
Dependent Claim 20 words
The invention as recited in claim 1 wherein said resilient container has a dispensing nozzle at an upper end thereof.
Claim 6
Dependent Claim 24 words
The invention as recited in claim 1 whrein said heating means comprise a plurality of heating elements each associated with one of said protrusions.
Claim 7
Dependent Claim 23 words
The invention as recited in claim 5 further including thermostatic control means operatively connected with said heating elements for regulating the temperature thereof.
Claim 8
Dependent Claim 23 words
The invention as recited in claim 6 wherein said thermostatic control means is adjustable to vary the regulated temperature of said heating elements.
Claim 9
Dependent Claim 33 words
The invention as recited in claim 4 further including circuit means interconnecting said plurality of heating elements for selectively causing the actuation of preselected ones of said heating elements independently of the others.
Claim 10
Dependent Claim 33 words
The invention as recited in claim 1 further including a heat transfer member attached to the recessed bottom of said container in permanent heat transfer relationship therewith and constructed of a thermal conductor.
Claim 11
Dependent Claim 16 words
The invention as recited in claim 1, said container consisting essentially of thermoplastic synthetic resinous material.
Claim 12
Dependent Claim 111 words
Heated dispensing apparatus comprising a base member; a plurality of protrusions formed as an integral part of said base member, each of said protrusions defining a generally horizontal, unbroken, aplanar support surface having a circular periphery; means embedded in said base member directly under said protrusions for exclusively heating said protrusions over substantially the entire exposed surface area thereof; and at least one unitary, resilient container removably disposed directly atop said base member for heating fluid within said container, said container having a recessed bottom of the same diameter as and conforming to said aplanar support surface for direct heat transfer contact therewith over the entire bottom surface of said container.
Claim 13
Dependent Claim 111 words
Heated dispensing apparatus comprising a base member; a plurality of protrusions formed as an integral part of said base member, each of said protrusions defining a generally horizontal, unbroken, aplanar support surface having a circular periphery; means embedded in said base member directly under said protrusions for exclusively heating said protrusions over substantially the entire exposed surface area thereof; and at least one unitary, resilient container removably disposed directly atop said base member for heating fluid within said container, said container having a recessed bottom of the same diameter as and conforming to said aplanar support surface for direct heat transfer contact therewith over the entire bottom surface of said container.
Claim 14
Dependent Claim 13 words
The invention as recited in claim 11 wherein said container is substantially cylindrical.
Claim 15
Dependent Claim 15 words
The invention as recited in claim 11 wherein said protrusions are at least partially curvilinear.
Claim 16
Dependent Claim 23 words
The invention as recited in claim 11 wherein at least one of said protrusions extends above the upper surface of said base member.
