  • Patent number: 7077185
    Abstract: A hand held tape dispenser for applying adhesive tape to a surface. The dispenser includes a housing for holding and dispensing a roll of tape and has a tape dispensing opening therein. A plurality of rollers are within the housing, the outer surfaces of which coact with each other and the tape to retain, guide and feed the tape through the opening. The outer surface of at least one of the rollers protrudes through the opening on one side thereof enabling frictional contact of the roller with the surface to be taped. When the tape dispenser passes over the surface in one direction the outer surface of the roller engages the surface and the tape causing it to roll and to coact and drive the other rollers. This causes the rollers to grip the surfaces of the tape and feed the tape through the opening enabling the tape to adhesively contact the surface and adhere thereto. The tape is cut off at the opening.

  • Patent number: 6874554
    Abstract: A tape dispenser having a frame, a cutter blade and at least one pair of projections disposed on the opposed interior surfaces of the side walls is disclosed. The distance between the projections is less than the distance between the interior surfaces of the side walls and is also less than the width of the tape held in the dispenser. The tape dispenser may also include a pair of tabs either associated with the projections or positioned between the projections and the tape mount. The dispenser is adapted to hold a roll of adhesive tape therein and because of the decreased distance between the projections, the tape assumes a convex shape when viewed from the front end of the dispenser. The shape of the tape and position of the tabs and projections causes the tape to be biased into contact with the interior of the front end of the dispenser. This helps to keep the free end of the tape out of contact with the roll in the dispenser.

The bags are wound around a core which can be retained on the axle so that the roll can rotate with respect to the axle when the axle is fixed within the dispensing device. A slot is provided in each separation line between adjacent bags, the slot adapted to engage a complementary tongue in the dispensing device for separating the individual bags. The width of the roll is such relative to the tongue that when an individual bag has been separated from the roll, portions of the next bag on the roll extend forwardly of the tongue where they are in a position to be grasped by a user and subsequently severed from the roll. The roller may include a feature for retarding rotation of the roll of bags relative to the axle.
