Description
[0001] The present invention relates to tape dispensers and more
particularly to dual tape dispenser for dispensing
reversed-conjoined tapes by having two rolls of tapes partially
offset with one of the tapes is reversed so that an adhesive edge
on the first tape is conjoined to a reversed adhesive edge on the
second tape when both tape ends are being dispensed together on the
same path.
BACKGROUND OF THE INVENTION
[0002] 1. Technical Field
[0003] Tape dispensing devices have been in use for many years.
There are tape dispensers made for dispensing a single tape,
multiple tapes for selections of different colors and sizes in all
of which are independent from one another. There are tape
dispensers conventionally used for dispensing masking tapes, duct
tapes, medical tapes, office tapes and other general purpose tapes.
Certain tape dispensers are used to dispense tape together with a
roll of paper or a folded plastic sheet in a roll as used for
sprayed painting, staining or texturing. These tape dispensers are
necessary tools for use in remodeling profession; however, there is
no prior art related to a dual tape dispenser which dispenses
reversed-conjoined tapes so that the remained adhesive portion of
the first tape is taped onto a substrate surface and the adjacent
reversed adhesive portion of the second tape is exposed and is
ready for user to attach other material to, such as an edge or a
folded edge of a plastic sheet or paper to mask off areas, such as
doors, countertops, refrigerator, etc., that are not supposed to be
sprayed with materials like paint, stain, wet join compound or
plaster for texturing when using a spraying machine; Also to mask
off framed openings, open spaces, ceilings and floors to prevent
dust, sprayed paint or stain, etc. from being blown into other
rooms; Or to be utilized for other purposes such as posting
posters, pictures, drawings and the like for office, home and/or
school display. Reversed-conjoined tapes works similar to
double-sided adhesive tapes but have several choices of different
pressure sensitive strengths with easily released pressure
sensitive adhesive that are intended for how many days they can be
used without leaving residue or damaging the surfaces to which they
are applied onto; Other types of tapes come in smaller tape rolls
can also be dispensed as a reversed-conjoined tapes to attain
double-sided adhesive tape feature, therefore it can be ripped
apart near the inside joined edges to avoid damaging to the
pictures, posters or drawings.
[0004] 2. Description of the Prior Art
[0005] Clearly all of the existing dispensers, such as tape
dispensers for desk top are for dispensing a single roll of tape or
multiple tape rolls to be dispensed individually. Closely related
to this invention is the Hand-Masker Dispenser by 3M company for
dispensing masking tape together with masking paper or folded
plastic sheet in a roll, offer certain features that are convenient
for certain tasks; However, in certain situations, those dispensers
would not be practical when user need to apply tape along the edges
and attach the edge of the plastic sheet or paper thereafter.
[0006] By way of contrast, the instant invention is directed to and
claims a method and apparatus of a dual tape dispenser holding two
roll of tapes to be dispensed together longitudinally with one of
the tape roll is reversed so that a portion of adhesive side of the
first tape is affixed to a reversed portion of adhesive side of the
second tape.
SUMMARY OF THE ADVANTAGES AND SCOPE OF THE INVENTION
[0007] An advantage of the present invention is to provide a dual
tape dispenser dispensing reversed-conjoined tapes with one of the
tapes is reversed so that an adhesive edge of the first tape is
conjoined longitudinally to a reversed adhesive edge of the second
tape when both tape ends are being dispensed together
simultaneously on the same path. Currently, there is none of the
tape dispensers on the market which dispenses two rolls of tapes
with one of which is reversed so that when one tape is affixed to a
substrate surface, the other reversed tape is exposed so that other
materials such as plastic sheet or paper can be easily attached to,
which is an ideal solution for painters and interior finishers when
they need to mask off certain areas to prevent paint, stain, join
compound, dust or the like from being blown into or onto.
[0008] Another advantage for many people is that users may use dual
tape dispenser dispensing reversed-conjoined tapes to post
pictures, drawings, posters and the like for office, home and/or
schools without using pins, or spending too much time making a loop
out of a one-sided adhesive tape. Pressure sensitive tapes comes in
a wide selection of how many days the tapes can be used without
leaving residue on the walls, without damaging the pictures or
posters and that the tapes can easily be removed.
[0009] Accordingly, this invention has an object to provide a dual
tape dispensing device of the character described above which is
technically simple to mass produce, simple to assemble and easy for
end user to use. These and other objects will be manifest when
considering the following detailed drawing specifications when
taken in conjunction with the appended drawing figures.

DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring to the drawings, and initially to FIG. 1-5, a dual
tape dispenser in accordance with the present invention is shown,
in FIG. 1, a dimetric view of an assembled dual tape dispenser
dispensing reversed-conjoined tapes. The components and their
positions are illustrated and described hereinafter as seen from a
front angle below the dispenser.
[0016] On the right side of FIG. 1 is the first tape-roll hub 21
with a tape roll 22 installed is positioned at the front on the
first housing panel 1. As when the tape end 29 is being pulled from
the first tape roll 22 which turns clockwise as viewed from the
right side as shown on FIG. 1 and FIG. 2, the tape end 29 being
pulled would travel toward the first cantilevered spindle 8, then
turn 180 degree to reverse the direction of travel toward the front
where the cutting blade 10 is snapped onto the cutting-blade
receptacle 6. The tape 22 being pulled would have the adhesive side
of the tape facing downward.
[0017] On the left side of FIG. 1 is the second tape-roll hub 19
with a tape roll 20 installed is positioned at the rear on the
second housing panel 2. A washer 18 and a bolt 17 hold the second
tape-roll hub 19 in place at the second housing panel 2 as seen on
FIG. 1. As when the tape end 30 is being pulled from the second
tape roll 20 which turns counterclockwise as viewed from the right
side as shown on FIG. 1 and FIG. 2., the tape end 30 being pulled
from the tape roll 20 would travel over the top of the second
cantilevered spindle 9 and partially under the first cantilevered
spindle 8 where the tape end 29 and 30 start to meet and partially
conjoin on the inside adhesive edges. On the opposite side of the
second cantilevered spindle 9 is the tape depressing bar 14 which
is pivottably attached to the second housing panel 2 with a washer
similar to washer 18 and a bolt 16 wherein the base portion of the
tape depressing bar 14 has a chamber where a torsion spring is
loaded within to gently help pressing the depressing end 15 against
the reversed conjoined portion of the tapes at under the first
cantilevered spindle 8. A cutting blade 10 has three different
functions comprising a cutting edge 13 for cutting tapes ends 29
and 30, a ramp where the reversed-conjoined tapes would have the
remained adhesive portion facing upward of the tape end 30 to
temporarily affix onto so that the tape ends 29 and 30 would be
easily torn off at the cutting edge 13, and a cut-a-way notch 12 as
can be seen on FIG. 5 to prevent the cutting blade 10 from sliding
horizontally. A structural wall 5 is part of the upper vertical
housing panel 1 and short wall 3 to give some strength for the
handle 24 to be attached to. At the rear end of the handle 24 is a
hanging bracket 26 with a hook 27 so that the user can hang the
dispenser temporarily on a belt, ladder or where suitable and
convenient. The bracket 26 is pivottably attached to the end of the
handle 26 by a cap 25 which can be tightened or loosen for the
bracket 26 to be adjustable and set at certain angle. The hanging
bracket 26 can be pivottably attached to the end of the handle 24
by pressure fitting so that the hanging bracket 26 can be adjusted
without adjusting the cap 25.
[0018] FIG. 2 shows the position of the components of the dual tape
dispenser as seen from the right side view of the dispenser,
including the tape dispensing path where the first tape roll 22 is
rotating clockwise where the tape end 29 is looping partially
around the first cantilevered spindle 8 and turn back toward the
front where the cutting blade 10 is position, see FIG. 5. When the
tape is ready to be cut, user would pull the reversed-conjoined
tape ends 29 and 30 slightly upward, therefore a portion of the
adhesive portion of the tape 30 facing upward to be affixed to the
ramp 11 portion of the cutting blade 10 where the
reversed-conjoined tape ends 29 and 30 can be cut at the cutting
edge 13. FIG. 2 also shows position of the short wall 3 where first
housing panel 1 and second housing panel 2 are connected in
relation to the first tape-roll hub 21, second tape-roll hub 20 and
the handle 24.
[0019] FIG. 3 shows the dual tape dispenser as viewed from the left
side of the dispenser where the first housing panel 1 is seen more
clearly in relation to the upper wall portion 4 and supporting
brace 5 being connected to the handle 24, and a short wall 3 where
first housing panel 1 and second housing panel 2 are connected. A
washer 18 and a bolt 17 hold the first tape-roll hub 21 in place on
the first housing panel 1 and the first tape roll 22 to be
installed onto the first tape-roll hub 21. As viewed from the left
side as illustrated on FIG. 3, when dispensing tapes, the first
tape-roll hub 21 with tape roll 22 installed would rotate
counterclockwise, and the second tape-roll hub 19 with tape roll 20
installed would rotate clockwise so that the tape ends 29 and 30
would become reversed and conjoined.
[0020] FIG. 4 shows the dual tape dispenser as viewed from above
the dispenser where the first housing panel 1 with a first tape
roll 22 installed is positioned on the right side of the first
housing panel 1, and the second tape roll 20 would be positioned
below the handle 24 and on the left side of the second housing
panel 2.
[0021] FIG. 5 shows the cutting blade 10 with three features
including a cutting edge 13 with tiny teeth, at least one cut-a-way
notch 12 to prevent the cutting blade from sliding side way, and a
ramp where the tape ends 29 and 30 would be temporarily affixed to
so that the reversed conjoined tapes would be cut easily.
[0022] Those skilled in the art will observe that the dual tape
dispenser dispensing reversed-conjoined tapes configured for use in
construction or remodeling industry is fabricated to utilize
masking tapes with 3 inch bore openings, and described in
connection with FIGS. 1, 2, 3, 4 and 5 of the drawings hereinbefore
can be modified to house and dispense tapes with smaller bore
opening such as 1 inch or 11/2 inches bore diameter for use in
offices, homes and schools.
[0023] Although but one embodiment of the present invention has
been illustrated and described it will be apparent to those skilled
in the art that various changes and modifications may be made
therein without departing from the spirit of the invention.
