Abstract: An enclosure for preventing certain organisms from escaping from an item susceptible to infestation into the surrounded environment and for preventing certain organisms from entering the item susceptible to infestation from the surrounding environment. The enclosure is defined by a flexible sheet material defining an interior space. The enclosure comprises a slit-like opening formed in the flexible sheet material through which an item susceptible to infestation can be inserted into the interior space defined by the enclosure.

Abstract: An enclosure for preventing certain organisms from escaping from an item susceptible to infestation into the surrounded environment and for preventing certain organisms from entering the item susceptible to infestation from the surrounding environment. The enclosure is defined by a flexible sheet material defining an interior space. The enclosure comprises a slit-like opening formed in the flexible sheet material through which an item susceptible to infestation can be inserted into the interior space defined by the enclosure. The slit-like opening is defined by a pair of opposed free edges of the flexible sheet material, and the slit-like opening extends between a first end and a second end. A sliding type fastener including a slide, extends from the first end to the second end of the slit-like opening wherein, when the slide of the sliding-type fastener is positioned at the first end, the slit-like opening is open.
