         3 . The closure system of  claim 1 , wherein the second member is moveable relative to the mouthpiece such that a terminal end of the second member is moveable from a first position to a second position relative to the mouthpiece, wherein the second position is further than the first position from the mouthpiece. 
     
     
         4 . The closure system of  claim 1 , wherein the straw assembly further includes a sealing portion between the first member and the second member to form a fluid tight seal between the first member and the second member. 
     
     
         5 . The closure system of  claim 1 , 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. 
     
     
         6 . The closure system of  claim 1 , wherein the first member further includes a filter holding portion spaced a distance from the second member engaging portion. 
     
     
         7 . The closure system of  claim 1 , further comprising:
 a filter member;   wherein the filter member is held within the first member to filter a material drawn through the straw assembly.   
     
     
         8 . The closure system of  claim 1 , wherein the straw assembly is affixed to the mouthpiece. 
     
     
         9 . 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. 
     
     
         10 . The closure system of  claim 9 , 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.   
     
     
         11 . The closure system of  claim 1 , wherein the engaging member includes a container engaging portion having a first engagement portion to engage a first container engagement feature and a second engagement portion to engage a second container engagement feature;
 wherein the first container engagement feature is distinct from second container engagement feature.   
     
     
         12 . The closure system of  claim 1 , wherein the second member is at least one of a telescoping member relative to the first member, flexible relative to the first member; breakable relative to the first member; interchangeable relative to the first member, or combinations thereof. 
     
     
         13 . The closure system of  claim 1 , wherein the second member comprises a terminal end of a surface engaging portion that is configured to engage an internal surface of the container;
 wherein the surface engaging portion defines a bore;   wherein 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.   
     
     
         14 . A closure system for a container, comprising:
 an engaging member having a mouthpiece engaging portion and a container engaging portion;   a mouthpiece extending from the engaging member and engaged by the mouthpiece engaging portion, wherein the mouthpiece is configured to be contacted by a mouth of a user;   a straw assembly extending from the mouthpiece, wherein the straw assembly includes:
 a first member extending from a first end to a second end, wherein the first end is fixed relative to the mouthpiece, and 
 a second member extending from a third end to a fourth end; 
 wherein the third end is at least partially receivable within the second end of the first member; 
 wherein the second member is configured to telescope relative to the first member from a first position to a second position; 
 wherein the fourth end of the second member is further from the second end of the first member in the second position than in the first position; and 
   a filter portion held within the first member.   
     
     
         15 . The closure system of  claim 13 , wherein the second end of the first member includes an internal cylindrical wall configured to engage an outer wall of the second member at the third end. 
     
     
         16 . The closure system of  claim 13 , further comprising:
 a sealing member positioned at the second end of the first member;   wherein the sealing member sealing engages the second member relative to the first member to limit a passage of fluid to within a flow passage through the second member and not around the second member into the first member.   
     
     
         17 . The closure system of  claim 13 , wherein the fourth end of the second member comprises a terminal end that is configured to engage an internal surface of the container;
 wherein fourth end of the second member defines a bore;   wherein 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.   
     
     
         18 . The closure system of  claim 13 , 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.   
     
     
         19 . The closure system of  claim 13 , 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;
 wherein the first container engagement feature is distinct from second container engagement feature.   
     
     
         20 . A method of selecting a length of a straw assembly within a container, comprising:
 extending a first member of the straw assembly to a first position relative to a second member of the straw assembly;   contacting a terminal end of the first member with a surface within a container;   pushing the first member into the surface with the second member to cause the first member to move to a second position relative to the second member;   maintaining an opening through a bore formed near the terminal end;   engaging an engaging member having a mouthpiece engaging portion and a container engaging portion to the container.
