Claims
- 1. A method for sequestering a fluid in a bag, comprising the steps of:
- receiving said fluid into an envelope through a one-way valve, said envelope containing a hydrophilic material, said fluid contacting said hydrophilic material;
- closing said one-way valve in response to contact between said one-way valve and said fluid in said envelope to prevent escape of said fluid from said envelope;
- gelling said fluid to form a gelled material in response to contact between said fluid and said hydrophilic material; and
- closing said one-way valve in response to contact between said one-way valve and said gelled material in said envelope to prevent escape of said gelled material from said envelope.
- 2. The method for sequestering a fluid in a bag a claimed in claim 1, wherein:
- said one-way valve comprises a flutter valve having a flattened pliable portion extending from said opening into said interior of said envelope;
- said step of closing said one-way valve in response to contact between said one-way valve and said fluid in said envelope comprises the step of contacting said fluid with said flattened pliable portion; and
- said step of closing said one-way valve in response to contact between said one-way valve and said gelled material in said envelope comprises the step of contacting said gelled material with said flattened pliable portion.
- 3. The method for sequestering a fluid in a bag as claimed in claim 2, wherein:
- said gellable hydrophilic material comprises a polymer; and
- said step of gelling said fluid to form a gelled material comprises the step of contacting said fluid with said polymer.
