1. A cartridge for retaining a mass, comprising: a fluid impermeable cup having an interior space, said cup including a bottom portion with a closed bottom and an open top defined by a top edge, and an annular wall terminating at an annular edge defining an open mouth for said cup, said annular wall including a bottom edge connected to said top edge of said bottom portion by an intermediate annular flange portion which extends away from an interior of said bottom portion;a foil joined with the cup to close said open mouth; anda fluid permeable filter that retains a mass and is joined to a cage, wherein said filter and said cage are received entirely in said interior space to reside below said foil and above and spaced from said closed bottom, and said cage rests against an interior surface of said cup to support said filter inside said interior space, said cage including a ring portion, a partially open base section defined by crossing members, and a plurality of spaced connectors connecting said base section to said ring portion,wherein said filter is received interiorly of said ring portion, is connected to and supported by said ring portion and continuously extends from said ring portion toward and over said partially open base section, and wherein said ring portion includes a top surface, a bottom surface, the top surface and the bottom surface of said ring portion each has an outer diameter that enables said ring portion to make an intimate, surface to surface contact with an interior surface of said annular wall of said cup along a surface of said ring portion that extends between said top surface and said bottom surface. 2. The cartridge of claim 1, wherein said base section is cross-shaped. 3. The cartridge of claim 2, wherein each said connector includes one end connected to said base section and another end connected to said ring portion. 4. The cartridge of claim 3, wherein each connector is connected to a bottom surface of said ring portion that faces said base section at an interior annular surface of said ring section. 5. The cartridge of claim 3, wherein each connector is connected to an interior annular surface of said ring portion. 6. The cartridge of claim 1, wherein said cup includes a flange portion radially extending away from said annular edge, and said foil is joined with said flange. 7. The cartridge of claim 1, wherein said filter and said cage are discrete bodies, and said filter is joined to said top surface of said ring portion. 8. The cartridge of claim 7, wherein said filter is a mesh. 9. The cartridge of claim 7, wherein said filter is a pouch, and said base section retards sagging of said filter. 10. A retainer for retaining a mass inside of a cup, comprising: a cage; anda fluid permeable filter joined to said cage, wherein said cage is configured to be received inside said cup and configured to be supported inside said cup, wherein said cage consists of a ring portion, a partially open base section defined by a cross-shaped web having four terminal ends, and four spaced connectors connecting said base section to said ring portion, each connector having an end connected to said ring portion and an opposite end connected to a respective terminal end of said cross-shaped web, and wherein said fluid permeable filter is received interiorly of said ring, includes a top portion that is joined to an upper, annular surface of said ring portion, and extends continuously from said upper annular surface of said ring toward and over said partially open base section of said cage, andwherein said ring portion is sized to make intimate, surface to surface contact with an interior annular wall of said cup. 11. The retainer of claim 10, wherein said ring portion has an outer diameter sized so that said ring portion makes intimate contact with an interior surface of an annular wall of said cup. 12. The retainer of claim 10, wherein said cage is comprised of plastic. 13. The retainer of claim 10, wherein each connector is connected to a bottom surface of said ring portion that faces said base section at an interior annular surface of said ring section. 14. The retainer of claim 10, wherein each connector is connected to an interior annular surface of said ring portion.
