         2 . The closure system of  claim 1 , wherein the second member is movable relative to the mouthpiece such that a terminal end of the second member is movable from a first position to a second position relative to the mouthpiece, the second position being further from the mouthpiece than the first position. 
     
     
         3 . The closure system of  claim 1 , wherein the second member has a first end, and the first member includes a second member engaging portion that defines a substantially cylindrical inner wall that engages the first end of the second member. 
     
     
         4 . The closure system of  claim 1 , wherein the straw assembly is affixed to the mouthpiece. 
     
     
         5 . The closure system of  claim 1 , wherein the engaging member includes a container engaging portion configured to removably fix the engaging member to the container. 
     
     
         6 . The closure system of  claim 5 , further comprising:
 an adapter member having a first engagement portion to engage the container engaging portion and a second engagement portion to engage the container.   
     
     
         7 . The closure system of  claim 1 , wherein the engaging member includes a container engaging portion having a first engagement portion that engages a first container engagement feature and a second engagement portion that engages a second container engagement feature, and the first container engagement feature is distinct from second container engagement feature. 
     
     
         8 . The closure system of  claim 1 , wherein the second member is one of telescoping, flexible, breakable, or interchangeable relative to the first member. 
     
     
         9 . The closure system of  claim 1 , wherein the second member has a terminal end of a surface engaging portion that is configured to engage an internal surface of the container, the surface engaging portion defines a bore, and the terminal end is configured to contact the internal surface of the container while the bore allows passage of a fluid through the second member. 
     
     
         10 . A closure system for a container, comprising:
 an engaging member having a container engaging portion;   a mouthpiece extending from the engaging member, the mouthpiece being configured to be contacted by a mouth of a user;   a straw assembly extending from the mouthpiece, the straw assembly including:
 a first member having a first end fixed relative to the mouthpiece and a second end opposite to the first end; 
 a second member having a third end and a fourth end opposite to the third end, the second member having an outer surface, wherein the third end is receivable within the second end of the first member such that the second member slides relative to the first member from a first position to a second position, the fourth end of the second member being further from the second end of the first member when the second member is in its second position than when the second member is in its first position; and 
 a sealing member positioned proximate to the second end of the first member, the sealing member frictionally engaging the outer surface of the second member to form and maintain a fluid tight seal between the first member and the second member as the second member moves in the first member; and 
   a filter member that filters a material drawn through the straw assembly.   
     
     
         11 . The closure system of  claim 10 , wherein the second end of the first member includes an internal cylindrical wall that is configured to engage an outer wall of the second member at the third end of the second member. 
     
     
         12 . The closure system of  claim 10 , wherein the fourth end of the second member defines a bore and is configured to engage an internal surface of the container, and the bore allows passage of a fluid through the second member. 
     
     
         13 . The closure system of  claim 10 , further comprising:
 an adapter member having a first engagement portion that engages the container engaging portion and a second engagement portion that engages the container.   
     
     
         14 . The closure system of  claim 10 , wherein the container engaging portion has a first engagement portion to engage a first container engagement feature and a second engagement portion to engage a second container engagement feature, and the first container engagement feature is distinct from second container engagement feature. 
     
     
         15 . A closure system for a container, comprising:
 an engaging member;   a mouthpiece extending from the engaging member;   a straw assembly extending from the mouthpiece, the straw assembly including:
 a first member; 
 a second member being movably coupled to the first member, the second member having an outer surface; and 
 a sealing member located between the first member and the second member, the sealing member frictionally engaging the outer surface of the second member to form and maintain a fluid tight seal between the first member and the second member as the second member slides in the first member; and 
   a filter member that filters a material drawn through the straw assembly.   
     
     
         16 . The closure system of  claim 15 , wherein the second member is movable relative to the mouthpiece such that a terminal end of the second member is movable from a first position to a second position relative to the mouthpiece, and the second position is further than the first position from the mouthpiece. 
     
     
         17 . The closure system of  claim 15 , wherein the first member includes a second member engaging portion that defines a substantially cylindrical inner wall to engage a first end of the second member, and a holding portion spaced a distance from the second member engaging portion, the filter member being located in the holding portion. 
     
     
         18 . The closure system of  claim 15 , wherein the first member has a first inner diameter, the sealing member is circular and has a second inner diameter, the second inner diameter being less than the first inner diameter. 
     
     
         19 . The closure system of  claim 18 , wherein the first member includes a notch formed therein, and the sealing member is located in the notch. 
     
     
         20 . The closure system of  claim 19 , wherein the first member includes a holding member coupled thereto, and the holding member retains the sealing member in the notch.
