Patent ID: 8602280

Claim:
An adhesive tape dispenser, including: a housing, the housing having a first wall, an opposite second wall, and a cavity between the first and the second walls, the second wall having a sliding axle protruding toward the cavity and a pressing portion which is able to protrude toward the cavity, the housing having an opening located between the first wall and the second wall, the housing also having a pivot axle disposed at the opening, a longitudinal direction of the pivot axle being perpendicular to the first and the second walls, the pivot axle partitioning the opening into a first opening and a second opening; a tape holder, being received in the cavity and having a first face and a opposite second face, the first face facing the first wall, the second face facing the second wall, the first face having a tape axle, a longitudinal direction of the tape axle being perpendicular to the first face, the second face having a first limiting piece and a second limiting piece, a sliding slot being defined between the first and the second limiting pieces to enable the sliding axle to slide inside, the first limiting piece having a fixed first end and a free second end, the second limiting piece having a free third end and a fixed fourth end, the first end corresponding to the third end positioninally, the second end corresponding to the fourth end positionally, the tape holder having a lateral face between the first and the second faces, the lateral face having a pivot hole to receive the pivot axle to enable the tape holder to pivot relative to the housing, the lateral face having a pressing end and an opposite cutting end, the pressing end being able to pivot toward inside of the first opening, the cutting end being able to pivot away from the second opening, a cutter being disposed at an end of the cutting end; wherein the tape holder is able to pivot between a closed position and an open position due to limitation of the sliding slot to the sliding axle; wherein when the tape holder is at the closed position, the lateral face covers the opening, the tape holder is located in the cavity completely; wherein when the tape holder is at the open position, the sliding axle abuts against a blocking portion of the third end of the second limiting piece, the pressing end enters the first opening, the cutting end leaves the second opening; wherein when the tape holder is at the open position and the pressing portion protrudes toward the cavity, the third end of the second limiting piece is pressed by the pressing portion to move toward the first wall of the housing, the sliding axle is thereby not blocked by the blocking portion and is able to leave the sliding slot to enable the cutting end to pivot away from the second opening further.
