Controlled drop dispensing tip

Abstract

A controlled drop dispensing tip includes a body suitable for attachment to a dispensing bottle and a nozzle having a lumen therethrough for flow of liquid formulation. An orifice is provided in the nozzle which is in fluid communication with the lumen therethrough for formulation of droplets. The nozzle is formed from a material enabling uniform droplet dispensment of the liquid formulation independent of downward angular orientation of the tip.

       2 . The tip according to  claim 1  wherein said material is a polymer.  
   
   
       3 . The tip according to  claim 2  wherein said polymer comprises a nanocomposite.  
   
   
       4 . The tip according to  claim 3  wherein said polymer comprises low-density polyethylene.  
   
   
       5 . The tip according to  claim 4  wherein said nanocomposite includes a nanofiller present in an amount of between about 9 and about 11% by weight.  
   
   
       6 . The tip according to  claim 4  wherein said nanocomposite includes a nanofiller present in an amount of about 10% by weight.  
   
   
       7 . A controlled drop dispensing system comprising: 
 a bottle;    a liquid formulation disposed in said bottle;    a tip having a body suitable for attachment to said bottle and a nozzle formed from a material enabling uniform droplet dispensement of said liquid formulation independent of downward angular orientation of said tip.    
   
   
       8 . The system according to  claim 7  wherein said material is a polymer.  
   
   
       9 . The system according to  claim 8  wherein said polymer comprises a nanocomposite.  
   
   
       10 . The system according to  claim 9  wherein said polymer comprises low-density polyethylene.  
   
   
       11 . The system according to  claim 10  wherein said nanocomposite includes a nanofiller present in an about of between about 9 and about 11% by weight.  
   
   
       12 . The system according to  claim 10  wherein said nanocomposite is present in an amount of about 10% by weight.  
   
   
       13 . The system according to  claim 12  wherein said liquid formulation comprises Alphagan®.  
   
   
       14 . The system according to  claim 12  wherein said liquid formulation comprises Refresh Liquigel®.  
   
   
       15 . A controlled drop dispensing tip comprising: 
 a body suitable for attachment to a dispensing bottle; and    a nozzle having a lumen therethrough for flow of a liquid formulation and an orifice in fluid communication with said lumen for the formation of droplets, said nozzle being formed from a material enabling uniform droplet size dispensement of said liquid formulation independent of downward angular orientation of said tip.    
   
   
       16 . The tip according to  claim 15  wherein said material is a polymer.  
   
   
       17 . The tip according to  claim 16  wherein said polymer comprises a nanocomposite.  
   
   
       18 . The tip according to  claim 17  wherein said polymer comprises low-density polyethylene.  
   
   
       19 . The tip according to  claim 18  wherein said nanocomposite includes a nanofiller present in an amount of between about 9 and about 11% by weight.  
   
   
       20 . The tip according to  claim 18  wherein said nanocomposite includes a nanofiller present in an amount of about 10% by weight.  
   
   
       21 . A method for controlling dispensed droplet size, said method comprising: 
 providing a squeezable bottle;    disposing a liquid formulation in the bottle;    attaching a dispensing tip to the bottle, the tip being formed from a material enabling uniform droplet dispensement of said liquid formulation independent of downward angular orientation of the tip; and    squeezing the bottle with the tip oriented in a downward direction to produce the uniform droplets of said liquid formulation.
