发明名称 Blade protector for tape dispenser
摘要 A tape dispenser that reduces accidental injury from contact with a sharp blade used to cut and separate tape from the dispenser when affixing the tape to a surface. The cutting blade, fixed at an angle some distance above an opening, or above the edge of a flexible plate, is not exposed unless enough pressure is applied to bend plate far enough to expose blade through and beyond the flexible plate. This invention provides a simpler, safer, more cost effective method of dispensing, affixing and cutting any material in tape form.
