To provide a novel rotation mechanism having a smaller number of components or parts. A double-sided tape applicator in which a rotation mechanism is incorporated includes a case and a closure 200 rotated relative to the case. A spiral sloped surface 212 is formed on a side of the closure 200. The case has an abutted member 131 provided at an end of a push member 130. When a user pushes the push member 130 to abut or compress the abutted member 131 against the sloped surface 212, the closure 200 is rotated.

Disclosed herein is a dispenser for adhesive fabrics or tapes, such as bandages or other adhesive medical fabrics or correction tapes. The dispenser has a case in which a supply reel and a take-up reel are mounted. A belt having adhesive fabrics or tapes thereon extends from the supply reel through one or more openings to the exterior of the case, and thence to a take-up reel. The supply reel and the take-up reel are coupled so that the belt is wrapped around the take-up reel as it is unwound from the supply reel and advances to move an adhesive fabric or tape to the exterior of the case for dispensing. The dispenser may optionally have an activation device that allows a user to extend a portion of an adhesive fabric outside the dispenser and dispense and apply the adhesive fabric to a human skin with one hand.

A tape applicator having an edge folding structure includes a main body and an edge folding block. The edge folding block is provided with a transverse press board, a longitudinal reverse folding block, a longitudinal reverse folding reinforcement block, and a longitudinal flattening board. A distance is defined between the flattening board and the reverse folding reinforcement block. An outer side of the reverse folding block is pivotally connected with a folding post. The tape applicator has a simple structure and can be assembled easily with the folding post to be pivoted to the outer side of the reverse folding block. The tape applicator enables the tape to form a nonstick side edge exactly for the user to tear off the tape from a packing.
