Abstract
An oxygen-absorbing composition containing particulate annealed electrolytically reduced iron of between about 100 mesh and 325 mesh in an amount of about up to 63% by weight, a salt such as sodium chloride in an amount by weight of about up to 3.5%, and a water-supplying component comprising activated carbon with liquid water therein of a mesh size of between about 20 mesh and 50 mesh in an amount by weight of up to about 85% in an envelope which will resist the passage of liquid water out of the envelope but will permit flow of oxygen into the envelope at a satisfactory rate.
Claims35
An oxygen-absorbing composition comprising in relatively sufficient proportions particulate annealed electrolytically reduced iron, salt for combining with water to produce an electrolyte which combines with said iron to cause it to absorb oxygen, and a water-supplying component comprising activated carbon with liquid water therein for supplying said water to said salt to produce said electrolyte.
A packet of an oxygen-absorbing composition comprising in relatively sufficient proportions particulate annealed electrolytically reduced iron, salt for combining with water to produce an electrolyte which combines with said iron to cause it to absorb oxygen, a water-supplying component comprising activated carbon with liquid water therein for supplying said water to said salt to produce said electrolyte, and an envelope for said composition comprising a laminate of ethylene vinyl acetate, water and grease resistant paper, and microperforated polyester film.
