ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to an adhesive tape dispenser, and more particularly to a quiet tape dispenser.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a tape dispenser
10
of the prior art comprises a handle
11
, a base
12
located over one side of the handle
11
, a cutting device
13
mounted on the front side of the base
12
, and a tape mount
14
disposed in the rear side of the base
12
. In operation, a tape roll
15
is mounted on the tape mount
14
such that one end of the tape roll
15
is pulled out to put through a roller
131
which is located under the cutting device
13
. The cutting device
13
has a cutting tool
132
for severing the tape. The prior art tape dispenser
10
described above is rather noisy while in operation. Such noise is often a source of annoyance in a workplace.
Now referring to
FIG. 2
, another prior art tape dispenser is basically similar in construction to the tape dispenser
10
shown in FIG.
1
and is patented (U.S. Pat. No. 5,549,255) by this inventor of the present invention. The second prior art tape dispenser is provided with a silencer
20
, which has a rotary shaft
23
capable of pressing the surface of the tape so as to enable the tape to be dispensed quietly. However, this second prior art tape dispenser is not good enough according to the opinion of this inventor of the present invention.
SUMMARY OF THE INVENTION
It is therefore the primary objective of the present invention to provide a tape dispenser which is quiet while in operation.
It is another objective of the present invention to provide a tape dispenser which is simple in construction.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by a tape dispenser, which comprises a handle, a base fastened with one side of an upper end of the handle, a cutting device fastened with the front end of the base, a shaft disposed in the proximity of the top end of an arcuate hole of the base, a sleeve fitted rotatably over the shaft, and a rotary rod disposed in the arcuate hole such that the rotary rod is capable of the arcuate displacement in the arcuate hole so as to cause the tape roll to be held between the shaft and the rotary rod. In operation, the tape is dispensed quietly in such a manner that the tape is gradually unrolled from the taper roll along the rotary rod.
The foregoing objectives, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
