         6 . The container of  claim 2 , wherein said sealing liner is attached to the closure outer skirt portion inner wall and the connecting bead. 
     
     
         7 . The container of  claim 2 , wherein said sealing liner is attached to the closure inner skirt portion outer wall and the connecting bead. 
     
     
         8 . A container, comprising:
 a container member having a bottom, an upper annular rim and a substantially continuous side wall extending from the bottom and terminating at the rim, the bottom and the side wall defining a first member cavity, the rim having a threaded closure means, and   a closure member having a peripheral sealing member with a circumference, said sealing member including an inner skirt portion having a substantially vertical outer wall, a connecting bead, and an outer skirt portion having a substantially vertical inner wall and connecting to the inner skirt portion at the connecting bead, and a sealing liner of different material than the inner skirt portion and the outer skirt portion wherein the sealing liner is situated between the inner skirt portion outer wall and the outer skirt portion inner wall, the outer skirt portion inner wall having a threaded closure means,   wherein sealable engagement of the container member and the closure member is effectuated when the sealing liner is in contact with the rim over a substantial length thereof.   
     
     
         9 . The container of  claim 8 , wherein the sealing liner is of lower durometer hardness that the closure member. 
     
     
         10 . The container of  claim 8 , wherein the sealing liner is of lower density that the closure member. 
     
     
         11 . The container of  claim 8 , wherein the sealing liner is attached to the closure member by a method from the group consisting of insertion, welding, and overmolding. 
     
     
         12 . The container of  claim 8 , wherein the sealing liner is in a form from the group consisting of a hollow form, a foamed form, and a solid form. 
     
     
         13 . A container, comprising:
 a container member having a bottom, an upper annular rim and a substantially continuous side wall extending from the bottom and terminating at the rim, the bottom and the side wall defining a first member cavity, the rim having a plurality of first threads and a sealing liner of different material than the rim, wherein the plurality of first threads are discontinuous around the container member, the plurality of first threads comprises at least two threads and the plurality of first threads has substantially equidistant engagement points, and   a closure member having a peripheral sealing member with a circumference, said sealing member including an inner skirt portion having a substantially vertical outer wall, a connecting bead, and an outer skirt portion having a substantially vertical inner wall and connecting to the inner skirt portion at the connecting bead, the outer skirt portion inner wall having a plurality of second threads adapted and positioned to cooperate with the first threads, wherein the plurality of second threads are discontinuous around the closure member and the plurality of second threads comprises at least two threads,   wherein sealable engagement of the container member and the closure member is effectuated when the sealing liner is in contact with the rim over a substantial length thereof.   
     
     
         14 . The container of  claim 13 , wherein said sealing liner is attached around the entire circumference of the rim. 
     
     
         15 . The container of  claim 13 , wherein the sealing liner is of lower durometer hardness that the rim. 
     
     
         16 . The container of  claim 13 , wherein the sealing liner is of lower density that the rim. 
     
     
         17 . The container of  claim 13 , wherein the sealing liner is attached to the rim by a method from the group consisting of insertion, welding, and overmolding.
