Estimating the term…
A method and means for transporting a quantity of comestibles (preferably at lowered temperatures) where at least continual monitoring of at least the oxygen level of the atmosphere to which the comestible is subjected is carried out. Preferably the carbon dioxide level is also monitored. Automatic adjustment of the oxygen content and carbon dioxide content in response to the monitoring is carried out using a positive infusion of ambient air and the scrubbing of the gas atmosphere to which the comestibles are subjected respectively. Ideally the comestibles are of a respiring nature such as would be the case with plants (whether cut or uncut), fruit and vegetables and they are carried in a container suitable for shipping where a seal of the container sufficient to ensure that less oxygen from the ambient air can diffuse into the container than is required for respiration by said quantity and sufficient to ensure a product of carbon dioxide by said quantity as a result of respiration than can diffuse from the container.
A shipping container adapted for having a quantity of respiring comestibles selected from plants, fruit and vegetables disposed and sealed therein sufficient to insure that less oxygen from the ambient air can diffuse into the container than is required for respiration by said quantity and sufficient to insure a production of carbon dioxide by said quantity than can diffuse from the container,
A shipping container adapted to be substantially sealed against a substantial infusion of ambient air and including a monitoring system for monitoring the oxygen content of its substantially sealed atmosphere and means automatically responsive to said monitoring system for providing a positive infusion of air into the container to raise the oxygen content therein when said oxygen content falls below a predetermined value.
A shipping container adapted to be substantially sealed against a substantial infusion of ambient air and including:
