ABSTRACT:
A cutting device angularly and removably attached to a heat-sealed edge of a food-contained polybag. The cutting device includes two integrally molded first and second parts. The first part is so formed that it has a tongue portion with two fixing pins raised from two outer comers of the tongue portion. A razor having a slant edge is clamped in locating grooves formed on top of the two fixing pins. The second part is formed with pin holes and a razor receiving groove corresponding to the fixing pins and the clamped razor. In use the cutting device is first positioned on the heat-sealed edge by folding the first part to the second part. Depressing the tongue portion of the first part will cause the razor to cut into the razor receiving groove on the second part and the polybag. Moving the cutting device sidewardly causes the razor to cut open the heat-sealed edge of the polybag.
