Abstract
An adhesive tape dispenser comprises a dispensing body and a blade. The dispensing body is of one-piece injection molded plastic construction and has a front portion for the mounting of the blade, two roll transport portions for rotatably fitting a roll of adhesive tape thereon, and at least one tensile anti-reverse member extended outward from the exterior surfaces of the roll transport portions and following the rotational direction of the adhesive tape roll during tape application. As such, the adhesive tape roll can be rotated forward to apply tape, but the adhesive tape roll cannot be easily rotated backward due to the braking action occurring at the rear extremity of the tensile anti-reverse member.
Claims4
A tape dispenser comprising:
- a dispensing body being of one-piece injection molded plastic construction, said dispensing body having a front portion, two side portions respectively extending back from the left and right ends of the front portion, two roll transport portions respectively protruding inward from the interior lateral surfaces of said side portions and adapted for the roll of adhesive tape having an inner circumferential surface rotatably fitting a roll of adhesive tape thereon, and at least one check portion disposed at the front ends of the interior lateral surfaces of said side portions;
- a blade mounted on the front portion of the dispensing body;
- at least one anti-reverse member stationarily fixed on the peripheral surfaces of the roll transport portions of the dispensing body, said tensile anti-reverse member having a curved portion extending outward from the outer periphery of the roll transport portions and oriented to follow the rotational direction of the roll of adhesive tape that is rotated forward in application, and a retarding portion rising slightly upward from the rear end of said curved portion engaged to the inner circumferential surface;
- wherein the tensile anti-reverse member permits the roll of adhesive tape to be rotated forward and resists rotation of the roll of adhesive tape backward.
