Abstract
A container system includes a bag having of one or more sheets of flexible polymeric material, the bag having an interior surface at least partially bounding a chamber, the chamber being adapted to hold a fluid. A flexible sparging sheet is secured to the interior surface of the bag so that a compartment is formed between the interior surface of the bag and the sparging sheet, at least a portion of the sparging sheet allowing gas to pass therethrough. A tubular port or tube is secured with the bag or the sparging sheet so that a passage bounded by the tubular port or tube communicates with the compartment.
Claims21
A container system comprising:
- a bag comprised of one or more sheets of flexible polymeric material, the bag having an interior surface at least partially bounding a chamber, the chamber being adapted to hold a fluid;
- a flexible sparging sheet secured to the interior surface of the bag so that a compartment is formed between the interior surface of the bag and the sparging sheet, at least a portion of the sparging sheet allowing gas to pass therethrough;
- and
- a tubular port or tube secured with the bag or the sparging sheet so that a passage bounded by the tubular port or tube communicates with the compartment.
A method for sparging a fluid with a gas, the method comprising:
- dispensing a fluid into a chamber of a bag, a flexible sparging sheet being secured to an interior surface of the bag so that a compartment is formed between the interior surface of the bag and the sparging sheet, at least a portion of the sparging sheet allowing gas to pass therethrough;
- and
- delivering a gas to the compartment so that the gas passes through the at least a portion of the sparging sheet and into contact with the fluid in the chamber.
