ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to an adhesive tape dispenser, and more particularly to a safety cover of the cutter of the adhesive tape dispenser.
BACKGROUND OF THE INVENTION
The U.S. Pat. No. 5,456,790 discloses a protective cover of the cutter of an adhesive tape dispenser, which comprises a clapper formed of a vertical plate and a horizontal plate, and a cover. The horizontal plate is provided with two pivoting lugs. The cover is provided with two retaining lugs, which are pivoted with the pivoting lugs. The cover is further provided with a locating block which presses against the horizontal plate at the time when the cover is lifted. The locating block presses against the vertical plate at the time when the cover is located at the covering position to shield the cutter.
Such a prior art cutter shield as described above is defective in design in that it is not cost-effective in light of an additional cost of a new molding tool for making the lugged plates. In addition, the prior art cutter shield is not compatible with the adhesive tape dispensers devoid of a clapper formed of the vertical plate and the horizontal plate.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an adhesive tape dispenser with a cutter shield which is simple in construction and compatible with a variety of adhesive tape dispensers.
The cutter shield of the present invention comprises a carrying seat and a cover pivoted with the carrying seat which is mounted over the cutter of an adhesive tape dispenser or stand. The cover can be swiveled between a covering position and an uncovering position.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
