         5 . The personal filtering liquid bottle of  claim 1  wherein:
 the housing is formed in its interior with an index indent; and 
 the cup is formed in its exterior with first and second radially spaced apart rib elements constructed to selectively register with the indent when the housing is in respective open and closed positions. 
 
     
     
         6 . The personal filtering liquid bottle of  claim 1  wherein:
 the cup is constructed to project above the top edge of the housing. 
 
     
     
         7 . The personal filtering liquid bottle of  claim 1  wherein:
 the housing includes a cap for covering the top thereof and a flexible tab connecting the cap to the housing. 
 
     
     
         8 . The personal filtering liquid bottle apparatus of  claim 1  wherein:
 the filter housing is formed in its upper portion with interior threads; 
 the cup is formed with a pair of oppositely disposed upwardly opening notches and the apparatus includes; 
 a plate for covering a cup, the plate including oppositely projecting lugs for engaging the respective notches and to project laterally outwardly from the notches to engage the threads and constructed to, upon rotation of the cover, rotate the cup and to engage the threads and be drawn into closing relationship with the cup. 
 
     
     
         9 . The personal filtering liquid bottle apparatus of  claim 8  wherein the apparatus includes:
 a spout cap for selectively covering the spout; and 
 a tether connecting the spout cap to the lid and constructed and so arranged as to, when the cup is rotated to move the outlet and inlet out of registration with one another, position the spout cap for closure on the spout. 
 
     
     
         10 . A personal fluid, self filtering fluid bottle lid device for fitting to the neck of a bottle having an upwardly facing opening and comprising:
 a lid formed with a peripheral skirt for fitting to the neck and configured on one side with a pour spout and further formed with a housing defining a well spaced laterally from the spout, the well including a bottom wall formed with at least one inlet;   a filter cup nested rotatably in the well, rotatable between open and closed positions and configured with a filter bottom wall including an inlet configured to be, when the housing is in the open position, registered with the outlet.   
     
     
         11 . The personal, self filtering fluid bottle cover of  claim 10  wherein:
 the cup is formed at its upper end with a latch element and the device includes; 
 a cap fitted rotatably on the well and including a catch element engageable with the latch element for rotation of the well with rotation of the filter cap. 
 
     
     
         12 . The personal, self filtering fluid bottle cover of  claim 11  that includes:
 a spout cap connectable with the spout and including a flexible tab is connected to the filter cap. 
 
     
     
         13 . The personal, self filtering fluid bottle cover of  claim 11  wherein:
 the filter plate is formed with at least one upwardly opening notch defining the latch element; and 
 the filter lid is formed with a dog engageable with the latch element. 
 
     
     
         14 . The personal, self filtering fluid bottle cover of  claim 10  that includes:
 a filter received in the housing. 
 
     
     
         15 . The personal, self filtering fluid bottle cover of  claim 10  that includes:
 a latch for releasably holding the cup in the well. 
 
     
     
         16 . The personal, self filtering fluid bottle cover of  claim 11  that includes:
 index means for indexing the rotational position of the cap relative to the well. 
 
     
     
         17 . The personal, self filtering fluid bottle cover of  claim 10  that includes:
 registration means for registering the position of the housing when in its closed position. 
 
     
     
         18 . The personal, self filtering fluid bottle cover of  claim 10  wherein:
 the well bottom wall is formed with a predetermined number of outlets; and
