Abstract
A moisture pod comprised of a flexible, porous water reservoir is enveloped in a water-impervious, flexible sheath. Registrating apertures in each of the reservoir and sheath allow water vapor to emanate from the pod to provide a stagnant, humid environment for a perishable comestible product when the moisture pod is packaged therewith, the apertures formed to preclude direct liquid water contact with the product.
Claims5
A moisture pod for use in a package of a perishable comestible product, consisting of:
- a. a water-containing, flexible, porous reservoir element of a water-absorbing material having an aperture formed therein and extending entirely therethrough;
- and
- b. a sheath of flexible, moisture-impervious film contiguous about and in closely enveloping relationship with said reservoir element, said sheath having an opening in at least one face thereof, said opening being smaller in diameter than said aperture and registering therewith, thereby permitting evolution or evaporation of water vapor from said reservoir element to the exterior of said sheath.
A moisture pod for use in cooperation with a package of a pre-packaged comestible product consisting of:
- a. a water-containing, flexible, porous reservoir element of a water-absorbing material;
- b. a sheath of flexible, moisture-impervious film contiguous about and in closely enveloping relationship with said reservoir element, said sheath having an opening in one face thereof;
- and,
- c. a tubular conduit attached to said sheath in registration with said opening, said conduit having a cutting edge formed on the distal end thereof.
