Containers for Fluids with Composite Agile Walls

Abstract

The disclosure is directed to sampling bags having flexible walls. The sampling bags may have agile walls that include a shape memory component. The shape memory component tends to return the sampling bag to its initial shape. Such sampling bags may be used in a variety of sampling methods.

1 . A fluid container, comprising:
 agile walls comprising a memory shape member.   
     
     
         2 . The fluid container of  claim 1 , wherein the memory shape member comprises a material capable of being deformed from an initial shape by the application of a force and returns substantially to its original shape after removal of the force. 
     
     
         3 . The fluid container of  claim 1 , wherein the memory shape member comprises a metal or plastic material. 
     
     
         4 . The fluid container of  claim 2 , wherein the initial shape of memory shape member comprises either a U-shaped, V-shaped, circular, arcuate, or parabolic cross section. 
     
     
         5 . The fluid container of  claim 4 , wherein the shape memory component has a rectangular, square, triangular, circular, “pillow” shaped with two parallel side walls, oval or other shape. 
     
     
         6 . The fluid container of  claim 1 , wherein the agile walls have a composite construction. 
     
     
         7 . The fluid container of  claim 6 , wherein the agile walls comprise at least three layers. 
     
     
         8 . The fluid container of  claim 7 , wherein the agile walls comprise an inner layer, the layer comprising the memory shape member, and an outer layer. 
     
     
         9 . The fluid container of  claim 1 , wherein the memory shape member is capable of biasing the sampling bag in an inflated configuration. 
     
     
         10 . The fluid container of  claim 9 , wherein the fluid container is a fluid sampling bag. 
     
     
         11 . The fluid container of  claim 1 , wherein the memory shape member is capable of biasing the sampling bag in a deflated configuration. 
     
     
         12 . The fluid container of  claim 11 , wherein the fluid container is a fluid delivery bag.
