ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a packing tool, and more particularly to a tape dispenser, which can prevent tape roll rotating backwards.
BACKGROUND OF THE INVENTION
FIG. 1
shows a conventional tape dispenser
90
mainly comprising a connecting board
91
, two side arms
92
at the opposite ends of the connecting board
91
, two annular roll mounts
93
at the interior sides of the side arms
92
respectively and a cutter
94
at front end of the connecting board
91
.
In use, a tape roll
50
is installed to the tape dispenser
90
between the side arms
92
with the roll mounts
93
inserted into the opposite ends of a central hole of the tape roll
50
for free rotation. The tape of the tape roll
50
is drawn out to the front side of the connecting board
91
to adhere to something and the cutter
94
can be used to cut the tape off.
Sometimes when the cutter
94
cuts the tape off, tension of the tape will make the tape roll
50
rotate backwards and cause the tail of the tape to run back on the tape roll
50
. The tape roll
50
may also rotate backwards because of its own weight or by an unexpected force. These events cause inconvenience to the user when the tape dispenser is next used.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a tape dispenser, which can prevent tape roll rotating backwards in unexpected situation to draw the tape back.
According to the object of the present invention, a tape dispenser comprises a main body having a connecting board, two side arms at opposite ends of the connecting board respectively and two roll mounts at interior sides of the side arms respectively for installing a tape roll between the side arms and inserting the roll mounts into a central hole of the tape roll. The roll mount is provided with at least a stop arm extended substantially parallel to the rotating axis of the tape roll, which has a free end to be pressed by the tape roll to provide a friction to the tape roll, and a cutting means for cutting a tape of the tape roll off.
