Package for draining an infusion bag

Abstract

A package for an infusion bag is disclosed comprising a cavity defined by front and rear opposing surfaces and top and bottom lids. The top lid outwardly biases top edges of the front and rear opposing surfaces for preventing the top edges from brushing against a string during retraction of the infusion bag. A lid is located on the bottom of the cavity, opposing the top lid, where the bottom lid has one free edge, and wherein inwardly biasing side edges of the surfaces outwardly biases the free edge of the bottom lid from the adjacent surface.

1 . A package for an infusion bag comprising a cavity defined by front and rear opposing surfaces and a top lid, where the top lid outwardly biases top edges of the front and rear opposing surfaces for preventing the top edges from brushing against a string during retraction of the infusion bag.  
   
   
       2 . The package of  claim 1 , where the opposing surfaces are joined at respective side edges, and the lid has at least one opening through which the string can retract the infusion bag into the package.  
   
   
       3 . The package of  claim 1 , having a lid on the bottom of the cavity, opposing the top lid, where the bottom lid has one free edge, and wherein inwardly biasing side edges of the surfaces outwardly biases the free edge of the bottom lid from the adjacent surface.  
   
   
       4 . The package of  claim 3 , wherein the bottom and top lids forming semicircular shapes around a centerline so that the front and rear surfaces forming semi-cylindrical shapes about the centerline.  
   
   
       5 . The package of  claim 3 , wherein the bottom of the rear surface has an extension with a shape that mirrors at least a portion of the bottom lid.  
   
   
       6 . The package of  claim 3 , wherein the lids each have a medial fold separating each lid into front and rear halves, where each half folds planar with the respective front and rear surface.  
   
   
       7 . The package of  claim 3 , wherein the width of the package is larger than the width of the infusion bag when the side edges are inwardly biased so that the infusion bag may be located entirely within the package.  
   
   
       8 . A method of forming a package for an infusion bag comprising the step of forming a cavity defined by front and rear opposing surfaces and a top lid, where the top lid outwardly biases top edges of the front and rear opposing surfaces for preventing the top edges from brushing against a string during retraction of the infusion bag.  
   
   
       9 . The method of  claim 8 , where the opposing surfaces are joined at respective side edges, wherein the method further comprises the step of forming at least one opening in the lid through which the string can retract the infusion bag into the package.  
   
   
       10 . The method of  claim 8 , further comprising forming a lid on the bottom of the cavity, opposing the top lid, where the bottom lid has one free edge, and wherein inwardly biasing side edges of the surfaces outwardly biases the free edge of the bottom lid from the adjacent surface.  
   
   
       11 . The method of  claim 10 , wherein the bottom and top lids form semicircular shapes around a centerline so that the front and rear surfaces forming semi-cylindrical shapes about the centerline.  
   
   
       12 . The method of  claim 10 , further comprising forming an extension on the bottom of the rear surface, where the extension has a shape that mirrors at least a portion of the bottom lid.  
   
   
       13 . The method of  claim 10 , wherein the lids each have a medial fold separating each lid into front and rear halves, where each half folds planar with the respective front and rear surface.  
   
   
       14 . The method of  claim 10 , wherein the width of the package is larger than the width of the infusion bag when the side edges are inwardly biased so that the infusion bag may be located entirely within the package.
