Hand operated fluid delivery device

Abstract

Embodiments of the invention provide a quick and easy way to dispense fluids, even in situations where space is tight or the fluid must be pumped against the force of gravity. No separate funnels, measuring devices, or pumps are needed. Thus, embodiments of the invention may be useful in any situation that requires the delivery of fluids from one container to another, and are recognized for being particularly useful in dispensing oil to automatic transmissions, or for dispensing oil to the rear ends of manual transmissions.

1 . A fluid delivery device comprising: 
 a collapsible enclosure that has a maximum volume when fully expanded and a minimum volume when fully collapsed;    a flexible tube attached to a first end of the collapsible enclosure; and    a volume adjustment device structured to vary the volume of the enclosure between the maximum volume and the minimum volume.    
   
   
       2 . The device of  claim 1 , the volume adjustment device comprising a roller attached to a second end of the collapsible enclosure, the second end opposite the first end.  
   
   
       3 . The device of  claim 1 , the volume adjustment device comprising an adjustable clamp that is configured to force the walls of the collapsible enclosure together.  
   
   
       4 . The device of  claim 2 , the collapsible enclosure tapered from the second end to the first end.  
   
   
       5 . The device of  claim 4 , the roller having a width that is greater than a width of the second end of the collapsible enclosure.  
   
   
       6 . The device of  claim 1 , the collapsible enclosure having measure marks configured to indicate the amount of fluid remaining in or expelled from the collapsible enclosure.  
   
   
       7 . The device of  claim 1 , further comprising a flow controller configured to adjust the flow of a fluid through the flexible tube.  
   
   
       8 . The device of  claim 1 , the flexible tube comprising a rigid neck attachment configured to be screwed into a matching rigid neck attachment located on the first end of the collapsible enclosure.  
   
   
       9 . The device of  claim 1 , further comprising a rigid port connected to the collapsible enclosure, the rigid port having interior threads and exterior threads, the rigid port configured to seal the collapsible enclosure when a matching plug is threaded inside the interior threads or when a matching cap is threaded over the exterior threads.  
   
   
       10 . The device of  claim 1 , further comprising a flange attached to a second end of the collapsible enclosure.  
   
   
       11 . An oil delivery device comprising: 
 a flexible enclosure structured to hold a maximum volume of oil;    a flexible tube attached to a first end of the flexible enclosure; and    a volume adjustment device structured to decrease the volume of the flexible enclosure from the maximum volume to a minimum volume by collapsing the walls of the flexible enclosure.    
   
   
       12 . The device of  claim 11 , further comprising a flow controller configured to adjust the flow of oil through the flexible tube.  
   
   
       13 . The device of  claim 12 , wherein the flow controller comprises a clamp.  
   
   
       14 . The device of  claim 11 , further comprising a circular rigid port attached to the flexible enclosure, the circular rigid port having a threaded inner surface.  
   
   
       15 . The device of  claim 14 , the threaded inner surface of the circular rigid port structured to securely hold a plastic oil bottle.  
   
   
       16 . The device of  claim 14 , the threaded inner surface of the circular rigid port structured to accept a threaded plug that seals the flexible enclosure.  
   
   
       17 . The device of  claim 14 , the circular rigid port comprising a threaded outer surface, the threaded outer surface configured to accept a threaded cap that seals the flexible enclosure.  
   
   
       18 . The device of  claim 11 , the volume adjustment device comprising a roller attached to a second end of the flexible enclosure, the second end opposite the first end.  
   
   
       19 . The device of  claim 18 , the flexible enclosure tapered from the second end to the first end.
