Abstract: Provided is a tape cutter comprising a housing comprising a rear spring, a forward opening, and a forward tape press roller; a tape dispensing unit urged by the spring and comprising a tape mount with an adhesive tape roll rotatably put thereon, and a push member projected from the opening; and a cutter unit pivotably mounted in the housing and comprising a front cutting blade and a top ridge. Placing the cutter on a surface to be sealed with the tape slightly projected from the opening and adhered on the surface and sliding the cutter will press the tape against the surface by the tape press roller for adhering thereto. After dispensing a desired length of the tape, pushing the push member will cause it to press down and pass over the ridge and press the blade to cut the tape off its roll with the spring being compressed.

Abstract: A rotary tape dispenser comprises a container including an inlet, an outlet, and a pin; a circular rotary plate having a portion exposed at the inlet and including a center hole, a plurality of cylinders around the center, a plurality of pairs of adjacent guide posts along the periphery wherein the number of the pairs of adjacent guide posts is equal to that of the cylinders, and a central sleeve put on and rotatable about the pin; a plurality of rolls of adhesive tapes wound on the cylinders, each roll having an open end pulled through the gap between the pair of guide posts; and a blade adjacent the outlet. The exposed portion of the rotary plate is counterclockwise rotatable to turn the rolls until one desired roll has turned to a position at the outlet. In response the roll can be pull and cut by the blade.
