ADHESIVE TAPE DISPENSER
FIELD OF THE INVENTION
The present invention relates generally to an adhesive tape, and
more particularly to a device for dispensing the adhesive tape.
BACKGROUND OF THE INVENTION
The conventional adhesive tape dispenser is provided with a rotary
wheel, which is capable of accommodating only the adhesive tape roll of
a specific size. In other words, the conventional adhesive tape dispenser
does not fit the tape rolls of various sizes. This implies that a variety of
tape dispensers must be purchased for the adhesive tape rolls of various
sizes.
SUMMARY OF THE INVENTION
The primary objective of the present invention is therefore to
21 93~a
provide an adhesive tape dispenser with an adjustable means enabling
the adhesive tape dispenser to hold and dispense the adhesive tape rolls
of various sizes.
In keeping with the principle of the present invention, the
foregoing objective of the present invention is attained by an adhesive
tape dispenser, which comprises a main body, a shaft jacket, and a rotary
wheel. The main body has a handle, a cutter, and a fixed shaft. The shaft
jacket is fitted over the fixed shaft and is provided on the outer wall
thereof with a plurality of parallel rails to facilitate the mounting of the
tape rolls of smaller sizes. The rotary wheel is provided with an axial
hole having in the inner wall thereof a plurality of parallel sliding slots
engageable with the parallel rails of the shaft jacket.
The foregoing objective, features and advantages of the present
invention will be more readily understood upon a thoughtful deliberation
of the following detailed description of an embodiment of the present
invention in conjunction with the accompanying drawings.

DETATl,~l) DESCRIPTION OF THE INVENTION
The adhesive tape dispenser of the present invention comprises a
main body 10, a shaft jacket 20, and a rotary wheel 30, as shown in FIGS.
1 -3.
The main body 10 is composed o~ a handle 11, and a frame plate
12 which is provided with a cutter 13 and a fixed shaft 14 having a
threaded hole 141. The cutter 13 has a stopping piece 131, a cutting edge
132 and a roller 133.
The shaft jacket 20 is tubular in shape and is provided with an
axial hole 21 dimensioned to fit over the fixed shaft 14. The shaft jacket
20 is filrther provided with a receiving recess 22 in which a cushion ring
23, an inner press ring 24, a spring 25, and an outer press ring 26 are
located. The shaft jacket 20 is secured to the fixed shaft 14 by a
fastening bolt 27 engageable with the threaded hole 141 of the fixed
shaft 14. The shaft jacket 20 in motion is forced to bring about a
damping effect by the inner press ring 24 which is exerted on by a
2193188
rotational motion of the outer press ring 26. The shaft jacket 20 is
provided on the outer wall thereof with three protruded rails 28 parallel
to one another and extending along the direction of the longitudinal axis
of the shaft jacket 20. The rails 28 are intended for use in mounting the
adhesive tape rolls of small sizes. The shaft jacket 20 is further provided
with a plurality of cuts 29, which are located respectively at one end of
the shaft jacket 20 and between two rails 28.
The rotary wheel 30 has three projected portions 31 located in the
periphery thereof for accommodating the adhesive tape rolls of greater
sizes. The rotary wheel 30 is provided with a center hole 32 having in
the inner wall thereof three parallel slide slots 33 engageable with the
protruded rails 28 of the shaft jacket 20. The center hole 32 is
dimensioned to fit over the shaft jacket 20 such that the slide slots 33 are
engaged with the protruded rails 28. Located between two slide slots 33
is a suspended elastic arm 34 capable of deformation and having a
retaining portion 341 engageable with the cut 29 of the shaft jacket 20,
as illustrated in FIG. 3. The rotary wheel can be disengaged with the
shaft jacket 20 by forcing the ret~ining portion 341 of the deformable
elastic arm 34 to disengage the cut 29.
As shown in FIG. 4, the rotary wheel 30 of the present invention is
intended for use in mounting a large-size adhesive tape roll. On the other
hand, the shaft jacket 20 is intended for use in mounting a small-size
adhesive tape roll, as shown in FIG.5. The protruded rails 28 of the shaft
jacket 20 serve to locate the small-size adhesive tape roll which is
mounted on the shaft jacket 20.
The embodiment of the present invention described above is to be
- 21 931 88
regarded in all respects as being merely illustrative and not restrictive.
Accordingly, the present invention may be embodied in other specific
forms without deviating from the spirit thereof. The present invention is
therefore to be limited only by the scopes of the following appended
claims.
