Abstract
Disclosed is an article of manufacture, comprising a hollow rod comprised of a longitudinally gathered tube of cellulose hydrate-based material, the hollow rod having a latent water content of between about 25% and 100% by weight based upon the total weight of the hollow rod and being free of chemical anti-bacteriocidal agent; a closed, substantially gas impermeable packaging sheath having a hollow interior chamber therein, with the hollow rod being positioned in the hollow interior chamber, whereby the hollow rod is completely enveloped by the packaging sheath, wherein the packaging sheath is comprised of a flexible film of material which is substantially impermeable to gases; and a protective gas essentially filling the remaining portion of the hollow interior chamber, with the gas protecting the hollow rod against the formation of aerobic microorganisms on the water-containing cellulose hydrate-based material.
