ABSTRACT:
A film-like closure opener opens a film-like closure such as a cap or lid which closes an open end of a bottomed tubular container such as a blood collecting tube. The film-like closure opener includes a cutter having a circular cutting edge for cutting off at least a substantial portion of the film-like closure along the open end of the tubular container. The opener may have a needle for piercing an elastic member on the film-like closure, so that the cut-off closure can be removed with the needle. The opener also has a gripper which is manually held and pushed to force the cutter into the tubular container while cutting off the film-like closure.
