Abstract:
An adhesive tape dispenser comprising:a dispensing body having a front portion, a rear portion, a pivot adjacent to the rear portion for pivotally mounting a roll of tape thereon, and a stop portion adjacent to the front portion; a roller pivotally mounted in the front portion of the dispensing body with the axis thereof parallel to that of the roll of tape, said roller having a plurality of protrusions arranged around the axis thereof at one end; a pawl pivotally hinged in the front portion of the dispensing body and having a pressing member which has an edge against the periphery of the roller, and an engaging portion at one end thereof which is capable of engaging in between two said protrusions; said pawl being stopped at said stop portion of the dispensing body when the pawl is pivoted towards the rear portion of the dispensing body, thereby preventing the roller being rotated backwards; an elastic member mounted in the dispensing body and adapted to force said pawl to be pivoted towards the rear portion of the dispensing body; a guide wheel pivotally mounted in the front portion of the dispensing body and disposed in front of the roller with the axis thereof parallel to that of the roller; a blade mounted on the front end of the dispensing body; wherein the tape is inserted between the periphery of the roller and the pressing member of the pawl and then routed over the periphery of the guide wheel to the blade; wherein said roller is rotated forwards when the roll of tape is rotated forwards during application such that the engaging portion of said pawl is pushed forwards by the protrusions of the roller and then engages in between the next two said protrusions.
