Abstract
Abstract A method of and apparatus for sealing containers for food products, comprising the steps of and means, respectively, simultaneously effecting the sealing of the peripheral zone of the cover on a corresponding flange of the neck of the container and effectively cooling the remainder of the surface of the closure cover, to obtain a pore-free hermetically tight closure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
An apparatus for sealing a circular closure cover onto a container having a flat annular flange, defining an open end of the container, comprising means for sealing a peripheral annular zone of a circular metallic closure cover onto an annular thermo-plastic flange of said container, means for simultaneously cooling the rest of the surface of said closure cover, thereby obtaining a pore-free tight closure, said sealing means comprises a hollow cylindrical sealing member including cylindrical walls having a flat annular bottom surface substantially of the same size as that of said annular flange of said container, and said hollow cylindrical sealing member adapted to be positioned with said bottom surface on said closure cover substantially directly above said annular flange of said container, heating means disposed in said cylindrical walls of said hollow cylindrical sealing member and extending to adjacent said bottom surface, a cylindrical cooling member disposed within said sealing member and having a lower closed circular surface flush with and along the same plane as said flat annular bottom surface of said sealing member, and cooling means in said cooling member for cooling said lower closed circular surface.
Claim 2
Independent Claim
190 words
An apparatus for sealing a circular closure cover onto a container having a flat annular flange, defining an open end of the container, comprising means for sealing a peripheral annular zone of a circular metallic closure cover onto an annular thermo-plastic flange of said container, means for simultaneously cooling the rest of the surface of said closure cover, thereby obtaining a pore-free tight closure, said sealing means comprises a hollow cylindrical sealing member including cylindrical walls having a flat annular bottom surface substantially of the same size as that of said annular flange of said container, and said hollow cylindrical sealing member adapted to be positioned with said bottom surface on said closure cover substantially directly above said annular flange of said container, heating means disposed in said cylindrical walls of said hollow cylindrical sealing member and extending to adjacent said bottom surface, a cylindrical cooling member disposed within said sealing member and having a lower closed circular surface flush with and along the same plane as said flat annular bottom surface of said sealing member, and cooling means in said cooling member for cooling said lower closed circular surface.
Claim 3
Independent Claim
284 words
An apparatus for sealing a circular closure onto a container having a flat annular flange, defining an open end of the container, comprising means for sealing a peripheral annular zone of said circular closure cover onto said annular flange of said container, means for simultaneously cooling the rest of the surface of said closure cover, thereby obtaining a porefree tight closeup, said sealing means comprises a hollow cylindrical sealing member including cylindrical walls having a flat annular bottom surface substantially of the same size as that of said annular flange of said container, and said hollow cylindrical sealing member adapted to be positioned with said bottom surface on said closure cover substantially directly above said annular flange of said container, heating means disposed in said cylindrical walls of saiD hollow cylindrical sealing member and extending to adjacent said bottom surface, a cylindrical cooling member disposed within said sealing member and having a lower closed circular surface flush with and along the same plane as said flat annular bottom surface of said sealing member, cooling means in said cooling member for cooling said lower closed circular surface, two supporting and clamping parts each having a semicircular recess facing one another and having a diameter complementary to the outer diameter of said container immediately below said flange, means for guiding and displacing said parts in a direction perpendicular to the axis of said container toward each other so as to abut each other complementarily surrounding and clamping said container immediately below said flange, and for separating said parts in order to remove said container after sealing of said closure cover, and said parts including upper surfaces upon which said flange is supported in said clamping position.
Claim 4
