Bellows-like fluid dispenser

Abstract

A readily collapsible viscous fluid dispenser is constructed in the general shape of a bellows to maximize the amount of fluid that can be stored while being kept small enough for one hand applied pressure dispensing. Rigid members are positioned on opposite sides of the readily collapsible bellows shaped viscous fluid enclosure. The rigid members are pivotably secured on either side of the discharge or the discharge end of the dispenser that can store and dispense different fluids by providing independent containers side by side with independent closures for each.

1 . A viscous fluid dispenser comprising: 
 a bellows-shaped collapsible container for the viscous fluid;    relatively rigid side members on opposing sides of said bellows-shaped collapsible container;    a dispenser head for said bellows-shaped collapsible container at its narrow inner end;    said relatively rigid side members being pivotally secured to said dispenser head;    a passage through said dispenser head, for discharging the viscous fluid, located between said relatively rigid side members in said dispenser head;    a closure means for blocking and unblocking said passage through said dispenser head.    
     
     
         2 . A viscous fluid dispenser as in  claim 1  wherein: 
 said closure has a passage that can be alined with said passage through said dispenser head for discharging the viscous fluid;  
 
     
     
         3 . A viscous fluid dispenser as in  claim 2  wherein: 
 said closure includes an arcuate surface that can be rotated to aline said dispenser head passage with said closure passage and to block said dispenser head passage.  
 
     
     
         4 . A viscous fluid dispenser as in  claim 1  wherein: 
 said bellows-shaped collapsible container is separated into independent first and second compartments for storage of different fluids.  
 
     
     
         5 . A viscous fluid dispenser as in  claim 4  wherein: 
 said dispenser head is provided with first and second independent closure means for said independent compartments.  
 
     
     
         6 . A viscous fluid dispenser as in  claim 5  wherein: 
 said dispenser head is provided with a first passage and a second passage;  
 said first closure means has a passage and said second closure means has a passage for independent alinement with said dispenser head first passage and said dispenser head second passage respectively.  
 
     
     
         7 . A viscous fluid dispenser as in  claim 5  wherein: 
 said first closure means and said second closure means both have an arcuate surface that can be rotated to block said dispenser first passage and said dispenser second passage respectively and that can be rotated to aline said first closure means passage with said dispenser first passage and said second closure means passage with said dispenser second passage respectively.  
 
     
     
         8 . A viscous fluid dispenser as in  claim 6  wherein: 
 said first closure means blocking said first dispenser head passage and said second closure means passage alined with said second head passage permits dispensing of the second fluid from said second storage compartment but precludes dispensing the first fluid from said first storage compartment.  
 
     
     
         9 . A viscous fluid dispenser as in  claim 6  wherein: 
 said second closure means blocking said second dispenser head passage and said first closure means passage alined with said first head passage permits dispensing of the first fluid from said first storage compartment but precludes dispensing of the second fluid from said second storage compartment.  
 
     
     
         10 . A viscous fluid dispenser as in  claim 6  wherein: 
 said first closure means alined with said dispenser first passage and said second closure means alined with said dispenser second passage permits dispensing from said first storage compartment and said second storage compartment simultaneously.  
 
     
     
         11 . A viscous fluid dispenser as in  claim 1  wherein: 
 said closure means is of the push-pull type with a horizontally pivoted spout for discharge.  
 
     
     
         12 . A viscous fluid dispenser as in  claim 1  wherein: 
 said closure means is of the threaded cap type.  
 
     
     
         13 . A viscous fluid dispenser as in  claim 1  wherein: 
 said closure means is of the vertically pivoted cap type.
