发明名称 Divisible tape tab for opening a container
摘要 A tab formed on a length of pressure-sensitive adhesive tape and having a cut in the tab permits tearing of the tab and tape lengthwise to open a hole in a flexible packaging material to expose the contents. The tape is placed over an opening formed in the material and the tearing of the tape tab by separating the two portions on either side of the cut will cause a tearing of the tape longitudinally causing a single tear at the opening to propagate in opposite directions from the opening.
