Claim 1
Independent Claim
200 words
A sterile carton comprising a plurality of side panels connected together to form a tube, one of said side panels comprising overlapping panel portions, an end closure attached to said panels to close and seal each end of said tube, a continuous substantially cut through line formed in said side panels terminating adjacent an edge of each of said overlapping panel portions to divide said tube into separable sections, a removable tape adhesively secured over said continuous cut line, a tab secured to an underside of said tape, removably attached adjacent to one edge of said overlapping panel portions and extending beyond the edge thereof in overlying and unattached relationship with respect to the other one of said overlapping panel portions to facilitate manual removal of said tape, and additional cut lines formed on opposite edges of said tape extending partially through said side panels adjacent to said continuous cuT line whereby sterile edge portions will be formed completely around said tube on at least one of said sections upon removal of said tape and underlying surface portions of said side panels for preventing the contamination of a sterilized item when it is removed from said tube upon separation thereof.
