ABSTRACT:
An improved straw hole design for a drink package which allows venting to occur in air gaps around the straw while the straw is inserted in the straw hole. This invention prevents the common problem of squirting or spill-over out of the top of the straw when a drink box is squeezed or otherwise compressed. Several embodiments are disclosed in which a "C" shaped pre-cut, a "U" shaped pre-cut and "V" shaped pre-cut are incorporated into the package for later insertion of the straw.
