Abstract
An adhesive tape dispenser is provided that includes a lower housing () that includes a pivot post () substantially perpendicular to a back wall of the lower housing, a back plate () assembly that includes a push button () assembly, a tape unwind spool (), a lower pin (), an upper pin (), and a wedge () that is slideably engaged with the lower housing, and a blade assembly unit () that includes a cutter arm (). The cutter arm includes a cutting blade () and a semi-tubular opening () that slideably engages the pivot post () of the lower housing. The cutter arm also includes an outer edge that guides along the wedge and lifts the forward end of the cutter arm (that includes the cutting blade) when the back plate assembly is urged forward by pressing the push button assembly forward. When the push button assembly is urged rearward, a lever arm and a lever foot () engage the upper and lower pin () of the back plate assembly forcing the cutter arm to pivot so that the front of the cutter arm is forced downward allowing the cutting blade to cut the adhesive tape.
