Abstract: 1. A nurser liner for containment comprising an elongated liner body having an open end and a closed end located opposite said open end; resilient rim located at said open end, means positioned adjacent and below said rim for spacing said rim from a rim of an adjacent second liner that lies said nurser liner positioned therein wherein said rim has a bead extending upward from an upper portion of said rim to prevent the liquid from leaking from between said nurser liner and the nipple, as said nurser liner is secured in the nurser holder and to prevent rotation of the nurser liner. 2. The nurser liner of Claim 1, wherein said bead has an arcuate, triangular or polygonal shape. 3. The nurser liner of Claim 1, wherein said bead is formed approximately at or the center of the top surface of the rim 4. The nurser liner of Claim 1 wherein said rim is more resilient than said liner body. 5. The nurser liner of Claim 1 wherein said means for spacing makes a clearance from about 0.75 cm to about 1.27 cm 6. The nurser liner of Claim 1 wherein said bead has an arcuate shape, and is formed at the center of the top portion of the rim. 7. The nurser liner of Claim 1 wherein said means for spacing having a single step, said step having a first surface that is located virtually parallel to the central axis of said liner body and a second surface that is located basically radial to said liner body but located a predetermined distance from said open end, wherein said second surface of said step of said second liner abuts said radial portion of said rim of said first liner so that said first liner is separated from said second liner by a predetermined separation length. 8. A nurser liner of Claim 1 wherein said rim having a radial portion and an axial portion, said axial portion having an inner circumference: and said liner having a single step being located adjacent said rim, said step having a first surface virtually perpendicular to said radial portion of said rim, and having a second surface basically parallel to said radial portion of said rim but located a predetermined distance from said rim, said second surface having an outer circumference, wherein said outer circumference of said second surface of said step is greater than said inner circumference of said axial portion of said rim, and wherein said step precludes a second nurser liner which has been stacked therein from contacting said rim thereby facilitating removal of the second nurser liner from said liner body. 9. The nurser liner of Claim 8, wherein said predetermined distance is the same as the extent of said first surface. 10. The nurser liner of Claim 8, wherein said first surface, as extended from said rim to said second surface, angles away from said liner body. 11. The nurser liner of Claim 8, wherein said angle of said first surface is about 0 degrees to about 30 degrees. 12. The nurser liner of Claim 8, said step includes a third surface and a fourth surfaces. 13. The nurser liner of Claim 12, wherein said third surface is substantially parallel to said first surface and said fourth surface is substantially parallel to said second surface. 14. The nurser liner of Claim 8, wherein said second portion of said step has an inner step circumference 15. The nurser liner of Claim 14, wherein said liner body includes a closed end located opposite said open end of said liner body with said closed end having an outer periphery, wherein said inner step circumference of said step is greater than the circumference of said outer periphery of said closed end. 16. The nurser liner of Claim 14, wherein the distance from said outer circumference of said second surface to said inner step circumference of said second surface is from about 0.25 mm to about 2.54 mm. 17. The nurser liner of Claim 16, wherein the distance from said outer circumference of said second surface to said inner step circumference of said second surface is about 0.5mm. 18. The nurser liner of Claim 16, wherein said liner body tapers circumferentially inward from said rim to said closed end. 19. The nurser liner of Claim 18 wherein said liner body tapers from said rim to said closed end by an angle no greater than about 2.0 degrees. 20. The nurser liner of Claim 19, wherein said liner body tapers from said rim to said closed end by an angle of about 0.7 degrees. 21. The nurser liner of Claim 8, wherein said inner circumference of said rim is about 142 mm to about 167 mm. 22. The nurser liner of Claim 21, wherein said inner circumference of said rim is about 151 mm. 23. The nurser liner of Claim 1, further comprising a plurality of beads extending upward from a portion of said rim. 24. The nurser liner of Claim 1, wherein said rim comprises at least one material selected from the group consisting of: low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, polypropylene and ethylene vinyl acetate. 25. The nurser liner of Claim 1, wherein said nurser liner together with said second liner is a portion of a plurality of nurser liners, wherein said first nurser liner is located in said second nurser liner and said means for spacing to prevent from contacting said rim of said first nurser liner and said rim of said second nurser liner and both nurser liners are separated by predetermined separation length of about 0.07 cm. to about 1.27 cm. 26. The nurser liner of Claim 25, wherein said predetermined separation length is about 0.25cm. 27. The nurser liner of Claim 8, wherein said nurser liner together with said second liner is a portion of a plurality of nurser liners, wherein said first nurser liner is located in said second nurser liner and said means for spacing to prevent from contacting said rim of said first nurser liner and said rim of said second nurser liner and both nurser liners are separated by predetermined separation length the same as the extent of said first surface. 28. The nurser liner of Claim 27, wherein said second liner, as extended from said open end to said second surface, angles away from said liner body. 29. The nurser liner of Claim 27, wherein said angle of said first surface is about 0 degrees to about 30 degrees. 30. The nurser liner of any Claim 1 or 28, wherein said first surface and said second surfaces meet at an arcuate edge. 31. The nurser liner of Claim 7, said step of said second liner includes a third surface and a fourth surfaces. 32. The nurser liner of Claim 31, wherein said third surface is substantially parallel to said first surface and said fourth surface is substantially parallel to said second surface. 33. The nurser liner of Claim 1 or 25, wherein said nurser liner body tapers inward from said means for spacing to said closed end. 34. The nurser liner of Claim 28, wherein said nurser liner tapers inward from said step to said closed end.
