         7 . The bottle as claimed in  claim 4 , wherein said shoulder of said bottle includes an annular ridge, said recessed engaging portion of said bottom of said bottle including an annular groove for securely receiving an annular ridge of said shoulder of said another similarly constructed bottle.  
     
     
         8 . A bottle comprising a bottom, a shoulder, and a mouth, said bottom including a first recessed engaging portion having a bottom wall, a second recessed engaging portion being defined in the bottom wall of said first recessed engaging portion, said first recessed engaging portion receiving a shoulder of another similarly constructed bottle, said second recessed engaging portion receiving a mouth of said another similarly constructed bottle, said first recessed engaging portion of said bottom of said bottle including means for releasably engaging with said shoulder of said another similarly constructed bottle such that said bottle and said another similarly constructed bottle are connected in series.  
     
     
         9 . The bottle as claimed in  claim 8 , wherein said shoulder of said bottle includes an outer threading, said first recessed engaging portion of said bottom of said bottle including an inner threading, for threadedly engaging with an outer threading of said shoulder of said another similarly constructed bottle.  
     
     
         10 . The bottle as claimed in  claim 9 , further comprising an O-ring mounted between said first recessed engaging portion of said bottom of said bottle and said shoulder of said another similarly constructed bottle.  
     
     
         11 . The bottle as claimed in  claim 8 , wherein said second recessed portion of said bottom of said bottle includes an inner threading for threadedly engaging with an outer threading of a mouth of said another similarly constructed bottle.  
     
     
         12 .
