Abstract
Abstract A container for boiling milk has a vertical cylindrical wall and a base divided into upper and lower flat walls staggered with respect to one another. An intermediate upright wall interconnects the upper and lower flat walls. A metal bottom disc is provided below, and in surface contact with, the lower flat wall, closing the bottom of the container and thereby defining a cooling space below the upper flat wall of the base. Several cooling plates, parallel to one another and to the base walls, are provided in this cooling space. They prevent boiling over of milk, brought to boiling temperature on the lower flat wall.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
Apparatus for boiling milk, comprising; a container having a generally vertical, generally cylindrical wall; a lower flat base wall disposed in a lower part of the container; an upper flat base wall parallel to the lower one and in a position staggered with respect to the same; an intermediate upright wall interconnecting the lower and upper flat walls and cooperating with them to close a lower part of the container; a metal bottom disc below and in surface contact with the lower flat wall and defining with the upper flat wall a cooling space in the lower part of the container; and a plurality of cooling plates mounted in said cooling space; whereby milk can be heated for boiling through said disc and said lower flat wall while being relatively cooled by said upper flat wall and said cooling plates in said cooling space to avoid boiling over of the milk.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
35 words
Apparatus according to claim 1 wherein the cooling plates are horizontal, semicircular, vertically spaced from and parallel to one another and secured to the upper flat wall and the bottom disc in parallel relation thereto.
Claim 4
Dependent Claim
54 words
Apparatus according to claim 2 including elongate bolts each securing the several cooling plates to the bottom disc and the upper flat wall, and sleeve means surrounding said bolts near and between said cooling plates to keep said cooling plates apart from one anotheR and from the upper flat wall and the bottom disc.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 1 wherein said bottom disc has a generally cylindrical flange secured to said generally cylindrical wall of the container.
Claim 6
Dependent Claim
16 words
Apparatus according to claim 4 wherein said flange has apertures providing ventilation for said cooling space.
