Multiple compartment pouch and beverage container with frangible seal

A flexible multiple-compartment pouch comprising:

• (a) a first sheet of polymeric film;
• (b) a second sheet of polymeric film superimposed on said first sheet of polymeric film wherein said first and second sheets of polymeric film are sealed to each other directly or indirectly through a third intervening polymeric film thus defining a sealed perimeter having a bottom end, an end opposing the bottom, and two opposed sides, forming a closed pouch;
• (c) at least one curved frangible seal extending from the end opposing the bottom end to one of said opposed sides and internal to the perimeter and said at least one curved frangible seal divides said closed pouch into separated compartments comprising a first compartment and a second compartment;
• and
• (d) a fluid confined to the fast compartment wherein the seal strength of said sealed perimeter is sufficient to withstand manual compression of the fluid and the seal strength of said at least one curved frangible seal is insufficient to withstand manual compression of the fluid thus allowing said fluid to commingle with the contents of the second compartment.
