Fluid dispensing device

Abstract

A dispensing device may be used to dispense fluids for a variety of uses. A dispensing device may include a flexible tube body with a nozzle coupled to a first end of the flexible tube body. A closure location may be coupled to a second end of the flexible tube body. At least one seal may be coupled to the flexible tube body at a location between the nozzle and the closure location. The at least one seal separates the flexible tube body into a plurality of chambers when the at least one seal is sealed. Additionally, a plunger may be placed in the flexible tube body and may fit in the chambers.

1 . A dispensing device comprising:
 a body having a substantially hollow interior;   an exit opening coupled to said body;   at least one seal coupled to said body; and   wherein said at least one seal is closeable.   
     
     
         2 . The dispensing device of  claim 1 , further comprising at least two seals, wherein said at least two seals are spaced along the body. 
     
     
         3 . The dispensing device of  claim 1 , wherein said body contains a fluid. 
     
     
         4 . The dispensing device of  claim 3 , wherein closing said at least one seal maintains internal pressure in said body after a portion of said fluid has been dispensed. 
     
     
         5 . The dispensing device of  claim 4 , wherein said at least one seal remains closed when external pressure is applied to a portion of said body containing said fluid. 
     
     
         6 . The dispensing device of  claim 3 , wherein a first seal of said at least one seal is closed after a first portion of said fluid has been dispensed from said dispensing device; and a second seal of said at least one seal is closed after a second portion of said fluid has been dispensed from said dispensing device. 
     
     
         7 . The dispensing device of  claim 1 , further comprising a plunger within said body. 
     
     
         8 . A dispensing device comprising:
 a flexible tube body;   a nozzle coupled to a first end of said flexible tube body;   a closure location coupled to a second end of said flexible tube body;   at least one seal coupled to said flexible tube body at a location between said nozzle and said closure location; and   wherein said at least one seal separates said flexible tube body into a plurality of chambers when said at least one seal is closed.   
     
     
         9 . The dispensing device of  claim 8 , wherein said at least one seal is coupled to said tube body at a location wherein said plurality of chambers each contain a predetermined amount of a fluid. 
     
     
         10 . The dispensing device of  claim 8 , further comprising a plunger in said flexible tube body. 
     
     
         11 . The dispensing device of  claim 8 , wherein said at least one seal may be opened by pulling said at least one seal apart from a side of said at least one seal adjacent to said second end of said tube body. 
     
     
         12 . The dispensing device of  claim 8 , wherein said at least one seal is closed by applying external pressure to said at least one seal. 
     
     
         13 . The dispensing device of  claim 8 , wherein said at least one seal is transverse to said flexible tube body. 
     
     
         14 . The dispensing device of  claim 8 , wherein said at least one seal is a resealable seal and is parallel to said flexible tube body. 
     
     
         15 . The dispensing device of  claim 14 , wherein said flexible tube body contains at least two substances and wherein at least one seal separates the at least two fluids. 
     
     
         16 . The dispensing device of  claim 15 , wherein said at least one seal is opened and said at least two substances are mixed prior to dispensing. 
     
     
         17 . A dispensing device comprising:
 a flexible hollow body having a proximal end and a distal end;   an exit opening coupled to said proximal end of said flexible hollow body;   a closure location coupled to said distal end of said flexible hollow body;   at least one seal coupled to said flexible hollow body at a location between said proximal end and said distal end; and   a plunger in said flexible hollow body.   
     
     
         18 . The dispensing device of  claim 17 , wherein said at least one seal is a resealable seal. 
     
     
         19 . The dispensing device of  claim 17 , further comprising a plurality of seals with spaces between each seal and wherein said plunger fits in said spaces. 
     
     
         20 . The dispensing device of  claim 17 , further comprising a closure coupled to said flexible hollow body at said closure location.
