The present invention provides a cutting strip which includes a flat, strip member adapted to be attached to the edge of a carton. The bleed valve is preferably designed to be a thermal valve. At least one organism selected from lactic acid bacteria, Enterococcuses, yeasts, and Baillus can be used along with the antibodies. The approach is flexibly applicable to software and systems development processes and the set of instantiation operations is extendable. The pockets are connected to each other between the bat handle ends and the bat head ends.
