Method for dispensing fluent material

Abstract

A method for dispensing a fluent material to articles which receive the fluent material. The method comprises the steps of selectively dispensing fluent material to the articles through open ends of nipples of a first flexible bag positioned for dispensing fluent material to the articles by deforming the nipples to eject fluent material therefrom. The open ends of the nipples of the first flexible bag are sealed. A second flexible bag having nipples is positioned for dispensing fluent material from the nipples to the articles, and fluent material is selectively dispensed to the articles through open ends of the nipples of second flexible bag by deforming the nipples to eject fluent material therefrom.

What is claimed is:  
     
         1 . A method of dispensing a fluent material to articles which receive the fluent material comprising the steps of: 
 selectively dispensing fluent material to the articles through open ends of nipples of a first flexible bag positioned for dispensing fluent material to the articles by deforming the nipples to eject fluent material therefrom;    sealing the open ends of the nipples of the first flexible bag;    positioning a second flexible bag having nipples for dispensing fluent material from the nipples to the articles;    selectively dispensing fluent material to the articles through open ends of the nipples of second flexible bag by deforming the nipples to eject fluent material therefrom.    
     
     
         2 . A method of dispensing a fluent material as set forth in  claim 1  further comprising the steps of: 
 sealing the open ends of the nipples of the second flexible bag;  
 positioning the first flexible bag for dispensing fluent material from the nipples to the articles;  
 unsealing the open ends of the nipples of the first flexible bag;  
 selectively dispensing additional fluent material to the articles through open ends of the nipples of the first flexible bag.  
 
     
     
         3 . A method of dispensing fluent material as set forth in  claim 1  wherein said step of sealing the open ends of the nipples of the first flexible bag comprises inserting removable plugs into the open ends of the nipples.  
     
     
         4 . A method as set forth in  claim 3  further comprising the steps of: 
 forming the flexible bag;  
 filling the flexible bag with the fluent material;  
 sealing the flexible bag by inserting the removable plugs.  
 
     
     
         5 . A method as set forth in  claim 4  wherein the step of filling the flexible bag is carried out in an aseptic environment.  
     
     
         6 . A method as set forth in  claim 4  further comprising sterilizing the flexible bag and fluent material after said filling step.  
     
     
         7 . A method as set forth in  claim 4  wherein subsequent to the sealing step and prior to the step of selectively dispensing fluent material, the method further comprises transporting the sealed flexible bag to a different location.
