     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0015]     The present invention a water bottle shown generally as  100  in  FIGS. 1 through 5 .  
         [0016]     Water bottle  100  includes the following major components, namely body  102 , spout  104 , neck  106 , cap  108 , top reinforcing rib  110 , middle reinforcing rib  112 , bottom reinforcing rib  114 , bottom  116  having a bottom cavity  118 , and a spout height designated as H shown as  120 .  
         [0017]     This plastic water bottle  100  is preferably made out of P.E.T. Plastic, which is blow moulded with conventional methods known in the art. The top portion  122  of water bottle  100  includes an elongated neck  106 , having a spout  104  and prior to use is capped off with cap  108 . The bottom  116  of water bottle  100 , includes a bottom cavity  118  which is dimensioned to accept spout  104  therein, such that when one water bottle  100  is stacked upon another water bottle  100 , the bottom  116  of water bottle  100  rests upon shoulder  130  of water bottle  100  as shown in the figures.  
         [0018]     An alternate embodiment of the present invention is shown as water bottle  200  in  FIGS. 6 through 11 .  
         [0019]     Water bottle  200  includes the following major components, namely body  213  including a top  211  having a spout  204  projecting upwardly there from. Spout  204  includes a spout top surface  205 . Body  213  also includes a bottom  245  including a bottom surface  219  and a bottom cavity  218  for receiving a spout therein when the water bottle  200  is in a stacked position  203  with another water bottle  200  as shown in  FIG. 13 . Spout  204  includes a neck portion  206 . Body  213  includes top surfaces  247  shoulders  208 , top reinforcing rib  210 , middle reinforcing rid  212 , bottom reinforcing rib  214 , bottom cavity  218  and bottom reinforcing grooves  250 . Bottom cavity  218  includes a cavity top surface  221  and cavity side walls  223 . The bottom reinforcing grooves  250  extending at least partially radially outwardly toward the outside diameter  217  of water bottle  200  to reinforce the bottom  245  of water bottle  200 .  
         [0020]     In the stacked position as shown in  FIG. 11  the upper or stacked water bottle is supported when bottom surface  219  of the upper water bottle  200  makes contact with top surfaces  247  of the lower water bottle  200 . In the stacked position as shown in  FIG. 11  the upper or stacked water bottle is also supported when cavity top surface  221  of the upper water bottle  200  makes contact with spout top surface  205  of the lower water bottle  200 . In this manner the weight is distributed onto the top surfaces  247  of lower water bottle proximate outside diameter  217  and also onto spout  204 . In this manner multiple contacts between the upper and lower bottle are created.  
         [0021]     In one embodiment the bottom surface  219  of the upper water bottle  200  makes contact with shoulders  208  of the lower water bottle  200 .  
         [0022]      FIG. 11  shows two water bottles  200  stacked one on top of each other in a stacked position  203 . In addition, the top water bottle shows a mould pre-form  260  which are used to blow mould water bottle  200 . In order to be able to stack water bottles  200 , one on top of each other without crushing the bottle on the bottom, a number of reinforcing ribs circumferentially around the outside diameter  217  including top reinforcing rib  210 , middle reinforcing rib  212  and bottom reinforcing rib  214 . The number and frequency of the positioning of these ribs can be altered in order to change the strength performance of the water bottle. Note that neck  206  of spout  204  is nested inside of bottom cavity  218  of the bottle just above. This feature makes it possible to put two or more bottles into stacked position  203 . The bottom surface  245  includes bottom reinforcing grooves  250  to help distribute the load along bottom surface  245 . Shoulder  208  is incorporated in top surface  247  in order to ensure that the load is transmitted down the side walls  249  of water bottle  200 . By incorporating shoulders  208 , the water bottle  200  can bear a greater amount of stackable weight and thereby make it feasible to stack one water bottle on top of another without crushing the bottle below.  
         [0023]     It should be apparent to persons skilled in the arts that various modifications and adaptation of this structure described above are possible without departure from the spirit of the invention the scope of which defined in the appended claim.
