Abstract: A container for carrying atmospherically sensitive items or perishables is provided that keeps the damage to the items at a minimum and also allows for extended duration containment of the items while minimizing quality degradation thereof, such as for shipping, display and/or storage. The container has a strong, robust container body such as formed of rigid walls that cooperate to form an internal space in which the items are received in a protected manner. To allow for a controlled exchange of gasses between the container interior space and the ambient exterior environment in accordance with the needs of the atmospherically sensitive items contained in the container for maintaining the product quality for long duration containment thereof, at least one of the container walls includes a window or port opening at which a semi-permeable membrane is mounted.
