Foaming device adaptable for the preparation of coffee and milk or cappuccinos or similar drinks and that can be assembled at home

A foaming device for the preparation of coffee and milk, cappuccinos or similar drinks, the device comprising:

• a cover for closing an opening of one of a plurality of substantially cylindrical containers, each container containing a liquid, said cover defining a rod receiving space;
• a rod extending axially through said rod receiving space in said cover such that a portion of said rod extends to a spaced location from said cover;
• a disk connected to said rod such that said disk is movable in an axial direction when said cover is attached to one of said containers, said disk extending in a direction perpendicular to said rod, said cover defining at least a first substantially concentric annular groove for contacting an upper edge of one of the containers having a first diameter greater than a diameter of said disk and a second substantially concentric annular groove for contacting an upper edge of another one of the containers having a second diameter less than said diameter of said disk, said disk having at least one mesh portion for forming an emulsion of air in said liquid contained in one of said containers, said disk having a flexible circumferential portion extending in a radial direction from an edge of said disk, said circumferential portion partially covering an opening defined between said edge of said disk and an internal wall of one of the containers having said first diameter, said circumferential portion bending when said disk is located within one of said containers having said second diameter.

A foaming device for the preparation of coffee and milk, cappuccinos or similar drinks, the device comprising:

• a cover for closing an opening of one of a plurality of substantially cylindrical containers having varying diameters, each container containing a liquid, said cover defining a rod receiving space;
• a rod extending axially through said rod receiving space in said cover such that a portion of said rod extends to a position located above said cover;
• a disk connected to said rod such that said disk is movable in an axial direction when said cover is attached to one of said containers, said disk extending in a direction perpendicular to said rod, said cover defining at least a first substantially concentric annular groove for contacting an upper edge of one of said containers and a second substantially concentric annular groove for contacting an upper edge of another one of said containers, said disk having at least one mesh portion for forming an emulsion of air in said liquid contained in one of the containers, said disk having a circumferential portion connected thereto, said circumferential portion being flexible such that said circumferential portion moves from a radial extending state to a bent state, said circumferential portion extending in a radial direction from an edge of said disk such that said circumferential portion partially covers an opening defined by said edge of said disk and an inner wall of one of the containers when said circumferential portion is in said radial extending state, said circumferential portion being in said bent state when said disk is located within one of said containers having a diameter that is less than a diameter of said disk with said circumferential portion.
