         14 . A method according to  claim 13 , wherein at least one neck portion of the spray bottle is blow molded as a portion of the wall of the spray bottle, and including a step of opening an end of said at least one neck portion after blowing molding the spray bottle.  
     
     
         15 . A method according to  claim 14 , wherein said step of opening is provided by one selected from the group consisting of a tool located external to blow mold, a tool located internal to blow mold, air jet located external to blow mold and air jet located internal to blow mold.  
     
     
         16 . A method according to  claim 1 , wherein at least two blow pins are utilized for molding the multi-neck spray bottle.  
     
     
         17 . A method according to  claim 16 , wherein each neck portion of the multiple neck spray bottle is formed with one separate blow pin.  
     
     
         18 . A method according to  claim 16 , wherein separate parisans are provided for each neck portion of the multiple neck spray bottle.  
     
     
         19 . A method according to  claim 1 , wherein said at least two parisans are extruded from hot plastic melt with one parisan being extruded about each blow pin.  
     
     
         20 . A method according to  claim 19 , wherein said two parisans are approximately equal length.
