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.

A rotary tape dispenser, comprising:
- a container including a base, said base having an inlet, an outlet, and a pin projected inwardly from about a center of said base, said container further having a cover releasably secured to the base;
- a circular rotary plate having a portion exposed at the inlet and including, at a side facing the cover, a plurality of cylinders disposed around a central hole thereof, and a plurality of pairs of adjacent guide posts along a periphery thereof, wherein a number of the pairs of adjacent guide posts is equal to a number of the cylinders;
- a plurality of rolls of adhesive tapes, each roll being wound on a respective cylinders, each of the rolls of adhesive tapes having an open end pulled through a gap between each pair of guide posts;
- and
- a blade adjacent the outlet;
- wherein in operation, the exposed portion of the rotary plate is rotated to turn the rolls of adhesive tapes until one of the rolls of adhesive tapes has turned to a position at the outlet, and the one roll of adhesive tape is pulled out of the outlet prior to being cut by the blade;
- and
- wherein the container further comprises an axial pawl on the pin, and the rotary plate further comprises a central sleeve projected inwardly from a periphery of the central hole, the central sleeve being put on the pin and an axial ratchet member inside the central sleeve being engaged with the axial pawl so that the rotation of the rotary plate is permitted only in a predetermined direction.
