Abstract

A watertight pump having a plunger used to causing air to be expelled from a nozzle of the pump. The plunger forms an interior compartment accessible by removal of a cap of the pump.

Claims

exact text as granted — not AI-modified
1 . A pump comprising:
 an outer enclosure operably engaged with an inner plunger, operation of the plunger causing air to be expelled from a nozzle of the pump;   a handle selectively securable to and removable from an outer terminus of the handle; wherein   the plunger forms an interior compartment accessible when the lid of the plunger is removed.   
     
     
         2 . The pump of  claim 1  where the pump is watertight when the lid is engaged with the handle. 
     
     
         3 . The pump of  claim 1  where the handle and lid are capable of lockable engagement with each other. 
     
     
         4 . The pump of  claim 1  including a gasket that surrounds a protrusion of the lid. 
     
     
         5 . The pump of  claim 4  where rotation of the protrusion of the lid within the compartment compresses the gasket. 
     
     
         6 . The pump of  claim 1  that floats in water. 
     
     
         7 . The pump of  claim 1  made of PVC.
