Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] This invention relates generally to tape dispensers. More
particularly, this invention relates to standing tape dispensers.
Specifically, this invention is directed to a tape dispenser which
is able to stand in two different orientations and retain the
cutter blade and the free end of the tape roll a distance away from
the surface upon which the dispenser rests.
[0003] 2. Background Information
[0004] A wide variety of tape and tape dispensers is available on
the market. The dispensers are particularly configured to receive
and hold particular tape roll sizes in a suitable orientation for
dispensing. A first group of dispensers have been designed to rest
on flat surfaces such as desktops. These dispensers typically
include a solid, heavy housing that rests on the desktop and
includes a horizontally oriented support for the tape roll. The
tape roll rotates about the horizontal support when tape is
dispensed therefrom. Typically, this type of dispenser will retain
fairly narrow width tape rolls. Other types of dispensers are
designed to be hand-held. For narrower width tapes these dispensers
may be manufactured from light weight, disposable plastic housings
that fit easily within the palm of a user's hand. For slightly
wider tapes, a group of hand-held dispensers may be fabricated from
stronger plastics, thereby making the dispensers more substantial
devices which can be reused. Yet other hand-held dispensers are
configured for ease of use for applying wider width tapes for
packaging and the like. Many of these dispensers are manufactured
from more durable materials as they will undergo repeated, heavy
duty use. A number of these packaging-type, hand-held dispensers
are known as "tape guns" and include a handle for the user to hold
onto the dispenser in a more comfortable fashion for a longer
period of time.
[0005] Yet another group of tape dispensers is able to be used
either as a hand-held dispenser or as a standing dispenser. This
type of dispenser is particularly useful for dispensing wider tapes
that are wound onto larger core rolls, for example tapes in the
order of 2'' in width, wound onto 3'' cores, in lengths of around
60 yards. Several U.S. patents have been issued for this class of
tape dispenser. For example, U.S. Pat. No. 5,672,238 (Samuelson)
and related Design Pat. No. D362,684 (Samuelson et al) disclose
hand-held/standing tape dispenser which includes a pair of front
legs and a pair of back legs. The dispenser has longer front legs
and shorter rear legs and is configured so that it may be used in a
standing position in a single orientation. In that single
orientation, the dispenser is able to stand on the tips of the
front legs and a region of the tape roll which is retained on a hub
between the front and rear legs. The dispenser disclosed in these
patents retains the cutter blade off the surface upon which the
dispenser rests but the user has to reach in under the horizontally
extending cutter blade in order to grab hold of the free end of the
tape. This can result in the user being accidentally cut by the
cutter blade.
[0006] U.S. Design Pat. D507,020 (Mueller et al) discloses a tape
dispenser that includes two pairs of legs positioned in front of a
hub for supporting the tape roll. The front legs are shorter than
the rear legs and when the tape roll is engaged on the hub, the
dispenser rests on all of the front legs, rear legs and a region of
the tape roll in a single orientation. The problem with this
dispenser is that the cutter blade extends toward the surface upon
which the dispenser rests and is held only a small distance off
that surface. The user has to reach into the dispenser under the
cutter blade to grasp the free end of the tape. Obviously, this
arrangement presents a bit of a safety hazard.
[0007] U.S. Design Pat. Nos. D442,227 and D448,413 (Carlson et al)
are able to be used as hand-held or standing tape dispensers. As
with the Samuleson et al dispenser, the Carlson et al dispensers
are able to be stood in a single orientation on a flat surface. The
rear legs of the Carlson et al dispensers are shorter than the
front legs thereof and the dispensers are therefore able to stand
on the tips of the front legs and a portion of tape roll. The
cutter blade extends horizontally from the front of the dispenser
and therefore presents the same type of hazard as the Samuelson et
al dispensers.
[0008] Several other patents disclose tape dispensers which have
two pairs of legs that are generally of the same length. U.S.
Design Pat. D573,645 (Sommers et al) falls into this category. This
dispenser may be used as a hand-held dispenser and may also be used
as a standing tape dispenser. Sommers et al illustrates in the
patent that the dispenser is able to rest on the top wall between
the front and rear legs in such a way that the legs extend
outwardly from the surface upon which the top wall rests. The
dispenser may also be flipped over and stood on two or four of the
almost equal length legs and/or portions of the tape roll. In
either standing position, the location of the cutter blade is less
than ideal and presents a cutting hazard for the user.
Additionally, if the tape dispenser stands on its legs, the
quantity of tape on the roll is critical because too much tape will
tend to create instability in the standing dispenser. This is
because the dispenser has to partially rest on the circumferential
surface of the tape roll. If the roll is almost full, the
circumferential surface of the roll may project for a distance
below the tips of the front and/or rear legs. The dispenser can
rest on the front legs and tape roll or on the back legs and tape
roll. The problem is that the dispenser can therefore move back and
forth between these two positions. This makes dispensing tape
slightly hazardous because the cutter blade may move suddenly to a
new position as the tape is withdrawn from the roll and pressure is
applied thereto to cut the tape.
[0009] There is therefore a need in the art for a tape dispenser
which is able to be used as a hand-held and standing dispenser;
which is configured to retain larger core, wider widths of tape
thereon, which will be able to stand on a flat surface in a stable
fashion during dispensing of the tape, and which includes a cutter
blade in a position within the dispenser that tends to be safer for
a user to access and cut the tape.
BRIEF SUMMARY OF THE INVENTION
[0010] A tape dispenser having a housing, a cavity within the
housing and within which a roll of tape is rotatably retained, and
pairs of front and rear legs. The housing is able to stand on a
flat surface in two different orientations. In a first orientation,
the housing is supported on curved tips of the front legs and a
region of the tape roll. In a second orientation, the housing is
supported by curved, rearwardly extending projections on the rear
legs and a second region of the tape roll. The housing rotates on
the tips or projections as tape is withdrawn from the roll. A blade
angles downwardly from the front end of the housing and is retained
a distance from the surface when the housing is in each of the
first and second orientations. The housing is rotated through about
ninety degrees between the first and second orientations.
[0011] The standing tape dispenser of the present invention has
advantages over the prior art in that the configuration tends to
keep the cutter blade and tape end off the surface upon which the
dispenser rests. Furthermore, the orientation and position of the
cutter blade relative to the surface upon which the dispenser rests
tends to pose less of a safety hazard than previously known
devices. Apart from the cutter blade being in a safer operational
position, it is also positioned so that the blade is in a more
natural orientation for a user to grasp and cut the tape than is
possible with previously known devices.

DETAILED DESCRIPTION OF THE INVENTION
[0025] Referring to FIGS. 1-11, there is shown a tape dispenser in
accordance with the present invention, generally indicated at 10.
Dispenser 10 is able to be used as a handheld dispenser but is also
able to be used as a standing dispenser in at least two different
orientations.
[0026] Dispenser 10 comprises a housing having a first side 12, a
second side 14, and a top wall 16 which extends between portions of
first and second sides 12, 14. A cutter assembly 18 is provided at
a front end 16a of top wall 16. Preferably, dispenser 10 is
fabricated from plastic. Cutter assembly 18 preferably is
fabricated from metal but may alternatively be fabricated from
plastic. Dispenser 10 is configured to engage and retain a roll of
tape 20 therein, most particularly adhesive tape. Roll of tape 20
includes a core 22 and an elongate length of adhesive tape 24 which
is wound onto core 22. Core 22 preferably is of the type that is
about 3 inches in diameter, with the tape 24 being around 1 inch in
width to around 2 inches in width. The width of top wall 16 of
dispenser 10 is configured to be complementary to the width of tape
24 to be dispensed from dispenser 10. The tape dispenser 10 in
accordance with the present invention preferably retains rolls of
tape 20 that are either 55' or 110' in length wound on 3'' diameter
cores. Dispenser 10 is able to retain these rolls 20 therein in a
stand-up configuration which keeps the free end 24a (FIG. 8) of
tape 24 from sticking to a surface 52 upon which dispenser 10
rests, and which positions a cutter blade 50 thereon in a safer,
more natural position for cutting than was the case in previously
known devices. Furthermore, dispenser 10 is configured so that it
is better able to keep the free end 24a of tape 24 from contacting
the surface 52 upon which the dispenser rests when dispenser 10 is
placed in a standing position in two different orientations. First
side 12 and second side 14 of the housing are mirror images of each
other. First side 12 is generally U-shaped when viewed from the
side and includes an exterior surface 12a, an interior surface 12b
(FIG. 4), a top edge 12c, a bottom edge 12d, a front edge 12e, and
a rear edge 12f. First side 12 further includes a front end 12g and
a rear end 12h. The front end 12g is the forwardmost region of
first side 12 and rear end 12h is the rearwardmost region of first
side 12. As shown in FIG. 2, bottom edge 12d is generally shaped as
a lower-case "r" when viewed from the right side.
[0027] First side 12 further includes a front leg 26, a rear leg
28, and a curved intermediate region 30 which extends between front
and rear legs 26, 28. Front leg 26 is located a short distance
inwardly from front end 12g of first side 12. Front edge 12e
defines the front region of front leg 26 and a portion 26a of
bottom edge 12d defines the rear region of front leg 26. Portion
26a preferably is straight and disposed substantially at right
angles to a longitudinal axis "Y" (FIG. 4) of dispenser 10. A tip
26b of front leg 26 transitions between front edge 12e and the
portion 26a of bottom edge 12d. Tip 26b is convex in shape, having
a curved outer surface which will contact the flat surface 52 upon
which dispenser 10 will stand. Tip 26b preferably is not of a
uniform radius of curvature between front edge 12e and the portion
26a of bottom edge 12d, and may include a slightly flattened
section 26b' (FIG. 2). The flattened section 26b' acts to limit
rotation of dispenser 10 beyond a certain point as tape 24 is
withdrawn from roll 20. Front leg 26 preferably is wider toward top
edge 12c of first side 12 and tapers moving away from top edge 12c
and towards the tip 26b. Front edge 12e is gently curved and is
disposed generally at an acute angle relative to portion 26a.
[0028] Rear leg 28 of first side 12 is located a spaced distance
rearwardly of front leg 26. Front and rear legs 26, 28 are thus
separated by a gap 13 (FIG. 2) from each other. A portion 28a of
bottom edge 12d forms a front region of rear leg 28. Portion 28a is
substantially straight along its length and is disposed generally
at right angles to longitudinal axis "Y" of dispenser 10. A tip 28b
of rear leg 28 transitions between portion 28a and rear edge 12f of
side 12. Rear edge 12f comprises the rear region of rear leg 28 and
rear end 12h of first side 12 comprises a projection which extends
rearwardly from the rear edge 12f of rear leg 28. The projection is
located proximate a top region of rear leg 28. The term "rear end
12h" will be used in the rest of this description to reference the
projection on rear leg 28. Both tip 28b and rear end 12h are convex
in shape and preferably have generally uniform radii of curvature
along their curved outer surfaces. The curved outer surface of rear
end 12h contacts flat surface 52 when dispenser is stood thereon in
a second orientation, as will be hereinafter described. Rear edge
12f forms a concave curve between tip 28b and rear end 12h and is
disposed at a generally acute angle relative to portion 28a. The
shape of rear edge 12f and position of tip 28b acts to limit the
rotation of dispenser 10 when in the second orientation. The
concavity of rear edge 12f prevents dispenser 10 from rotating on
surface 52 on rear edge 12f. Consequently, when tip 28b engages
surface 52 it acts as a positive stop and prevent further rotation
of dispenser 10 about the curved surface of rear end 12h.
[0029] Front edge 12e of front leg 26 and rear edge 12f of rear leg
28 angle outwardly in generally opposite directions to each other
when viewed from the side. Rear leg 28 is wider proximate top edge
12c of first side 12 and tapers toward tip 28b. It should be noted
that front leg 26 and rear leg 28 are disposed generally in the
same longitudinal plane (FIG. 5) and are longitudinally aligned
with each other.
[0030] In accordance with a specific feature of the present
invention, front leg 26 is longer than rear leg 28, i.e., front leg
26 extends downwardly from top edge 12c of first side 12 for a
greater distance than does rear leg 28. Tip 26b of front leg 26 is
spaced a distance "D" (FIG. 2) further away from top edge 12c than
is tip 28b of rear leg 28. Preferably, tip 28b of rear leg 28 is
disposed less than half way along the front leg 26 when measuring
from top edge 12c.
[0031] As indicated previously, second side 14 is a mirror image of
first side 12 and will therefore not be described in any detail
other than to identify components identical to those on first side
12 and to provide those components with reference numbers. Second
side 14 includes an exterior surface 14a, an interior surface 14b
(FIG. 4), a top edge 14c, a bottom edge 14d, a front edge 14e, a
rear edge 14f, a front end 14g, and a rear end 14h. Second side
further includes a front leg 27 and a rear leg 29, and a curved
extension 31 (FIG. 3) which is disposed between them. Front leg 27
includes a portion 27a of bottom edge 14d and a tip 27b. Rear leg
29 includes a portion 29a of bottom edge 14d and a tip 29b. Rear
end 14h is part of rear leg 29. The term "rear end 14h" will be
used in the rest of this description to reference a projection
which extends rearwardly on rear leg 29 and corresponds to the
projection/rear end 12h on first side 12. Front leg 27 is a mirror
image of front leg 26 in position, structure and function; and rear
leg 29 is a mirror image of rear leg 28 in position, structure and
function.
[0032] Exterior surface 12a of first side 12 is substantially flat
along its length from front end 12g to rear end 12h thereof, with
the exception of a gripping region 32 which projects outwardly from
exterior surface 12a and a slight inward jog illustrated in FIG. 4.
Gripping region 32 is disposed a short distance inwardly from front
end 12g and comprises a series of alternating ridges and valleys
which are oriented substantially at right angles relative to the
longitudinal axis "Y" of dispenser 10. Gripping region 32
preferably is generally triangular in shape when viewed from the
side of dispenser 10 and originates adjacent a horizontal section
of front edge 12e. Gripping region 32 extends for a distance toward
top edge 12c of first side 12. In a similar fashion, second side 14
includes a gripping region 33 which is substantially identical in
structure and function to gripping region 32 on first side 12 and
is disposed opposite thereto.
[0033] Interior surface 12b of first side includes a tape rest 34
which extends inwardly therefrom and toward second side 14. Tape
rest 34 thus projects for a short distance into the cavity between
first and second sides 12, 14 of the housing. Tape rest 34 is
located proximate front edge 12e and a short distance downwardly
from a bottom end 32a of gripping region 32. Interior surface 14b
of second side 14 includes a substantially identical tape rest 35.
Tape rests 34, 35 are positioned and oriented to present a surface
upon which a free end 24a of the tape is able to rest between
dispensing episodes.
[0034] A first hub section 36 extends inwardly from interior
surface 12b of first side 12 and towards second side 14. First hub
section 36 is located rearwardly of tape rest 34. First hub section
36 is generally semi-circular in cross-sectional shape and is
complementary to the curvature of the tape roll 20 that is to be
engaged therewith. FIG. 5 shows that first hub section 36 includes
a rear wall region with a first locking detent 38 disposed thereon.
A second hub section 42 extends inwardly from interior surface 14b
of second side 14 and towards first side 12. Second hub section 42
includes a rear wall region with a second locking detent 40
disposed thereon. First locking detent 38 is configured to
interlockingly engage complementary second locking detent 40 and to
thereby secure rear wall regions of first and second hub sections
36, 42 together. This interlocking engagement effectively prevents
the rear wall regions of first and second sides 12, 14 from
accidentally separating from each other. Locking detents 38, 40 may
be temporarily engaged with each other or may be permanently fixed
together by any suitable means such as heat welding or application
of an adhesive after tape roll 20 has been positioned within
dispenser 10.
[0035] As indicated earlier herein, top wall 16 extends between
first and second sides 12, 14. Top wall 16 includes a front end
16a, a rear end 16b, and a first section 16c, a second section 16d
disposed between front and rear ends 16a, 16b, and shoulder regions
16e located in the transition zone between first and second regions
16c, 16d. Front end 16a extends between front ends 12g, 14g (FIG.
4) of first and second sides 12, 14. First section 16c of top wall
16 originates at first end 16a and terminates in a position
generally aligned with a rear end of gripping regions 32, 33. First
section 16c is integrally formed with or secured to a region of the
top edge 12c of first side 12 and to a region of the top edge 14c
of second side 14. First section 16c is flat and is of a length "L"
(FIG. 4). First section 16c has a width "W" that is substantially
equal to the width of the front end 10a (FIG. 5) of dispenser 10.
Dispenser 10 narrows in width at the "jog" in the first and second
sides 12, 14 and the remaining part of dispenser is therefore
marginally narrower than width "W", as can be seen in FIG. 4. Thus,
dispenser 10 is wider at its front end 10a and is narrower at its
rear end 10b. This configuration gives first and second sides 12,
14 a slight spring action when their second ends 12h, 14h are
pulled apart to insert tape roll 20 between them, as will be
described hereafter. This spring action helps retain tape roll 20
between first and second sides 12, 14 prior to locking detents 38,
40 being engaged with each other.
[0036] Second section 16d of top wall 16 originates at the
rearwardmost region of first section 16c, extends rearwardly away
therefrom and toward rear ends 12h, 14h of first and second sides
12, 14, terminating in second end 16b. Second section 16d is an
elongate convexly-curved member that is of a width "W1" that is
smaller than the width "W" of first section 16c. The width "W1" of
second section preferably is also slightly narrower than the gap
between the innermost surfaces 36a, 42a of first and second hubs
36, 42, as is illustrated in FIG. 4. Thus, a gap (not numbered) is
defined between interior surface 12b of first side 12 and first
side edge 16f of second section 16d, and between interior surface
14b of second side 14 and second side edge 16g thereof. The
curvature of second section 16d is complementary to the curvature
of tape roll 20 and second section 16d will be spaced a short
distance above roll 20. Second end 16b of top wall 16 is spaced a
distance forwardly from rear ends 12h, 14h of first and second
sides 12, 14.
[0037] In accordance with yet another feature of the present
invention, first section 16c of top wall 16 defines an aperture 44
therein. Aperture 44 may be of any desired configuration but in the
preferred embodiment of the invention, aperture 44 is generally
triangular in shape. Aperture 44 decreases the overall weight of
top wall 16 and also serves to indicate to the consumer where the
front end of dispenser 10 is located inasmuch as the apex of the
triangular aperture 44 is proximate cutter assembly 18.
[0038] In accordance with yet another feature of the present
invention, first section 16c of top wall 16 also includes a concave
indentation 46. Indentation 46 is configured to receive a fingertip
of user therein. A front end 46a of indentation 46 preferably
originates in the base of the triangular aperture 44. The rear end
46b of indentation 46 is disposed generally in alignment with the
shoulder regions 16e of first section 16c. The portion of
indentation 46 which extends between the front and rear ends 46a,
46b is generally oval in shape, and extends generally along the
longitudinal axis "Y" of dispenser 10. A plurality of alternating
ridges and valleys (not numbered) are provided on the exterior
surface of fingertip indentation 46. The ridges and valleys
preferably are oriented at right angles to the longitudinal axis
"Y". These ridges and valleys provide a gripping surface within
indentation 46.
[0039] Cutter assembly 18 is secured to front end 16a of top wall
16 and includes a housing 48 (FIG. 5) with a blade 50 mounted
therein at right angles to longitudinal axis "Y". The blade 50 and
the teeth (not numbered) on blade 50 extend outwardly to a
sufficient degree from housing 48 to be positioned to cut tape 24
when a length thereof is withdrawn from tape roll 20. In
particular, blade 50 is positioned so that it angles downwardly
within dispenser 10 in such a manner that when dispenser 10 stands
on surface 52 in a first orientation (shown in FIGS. 8 and 9), the
blade 50 extends toward the surface 52. In particular, blade 50
extends downwardly at an angle away from the plane "P" (FIG. 2)
along which first section 16c of top wall 16 is disposed. This
orientation of blade 50 provides for safer use of the dispenser 10
when in a standing position in either of the first or second
orientations, which will be further described herein.
[0040] Dispenser 10 is used in the following manner. Tape roll 20
is engaged in dispenser 10 by disengaging first and second detents
38, 40 (FIG. 5) at the rear end 10b of dispenser 10, moving the
first side 12 and second side 14 away from each other in the
directions indicated by arrows "A" and "B" and sliding tape roll 20
into the cavity defined between the interior surfaces 12b and 14b.
Tape roll 20 is engaged on first and second hub sections 36, 42 and
first and second sides 12, 14 are then secured together by engaging
first and second detents 38, 40. At this point, tape roll 20 is
engaged in dispenser 10 in the manner shown in FIG. 1 and the full
length of tape 24 is wound around core 22 of roll 20. Dispenser 10
can be used at this point as a handheld dispenser. As will be
understood, dispenser 10 may be held in a user's hand while tape 24
is dispensed therefrom. In order to do this, the user will grasp
dispenser 10 in their right hand, for example, and will place the
thumb of their right hand on the gripping surface 32 on first side
12 and one or more of their right middle, right ring, and right
little fingers on the gripping surface 33 on second side 14. The
user will additionally position their right index finger's tip in
the fingertip indentation 46 on top wall 16. The user's index
finger and possibly a portion of their palm will rest on second
section 16d of top wall 16. When dispenser 10 is held in this
manner, tape 24 may be dispensed therefrom.
[0041] FIGS. 2 through 5 show a variety of orientations in which
dispenser 10 can be stood on a surface 52. In each of these
orientations, dispenser 10 is able to stand on surface 52 in such a
way that a free end of the tape 24 on roll 20 is able to be kept
from contacting surface 52 and is presented in a suitable position
for quick and easy dispensing from the dispenser 10. Additionally,
blade 50 is kept a distance away from surface 52. It should be
noted that dispenser 10 is stable, i.e., does not tend to fall over
or rock, in these various orientations regardless of how much tape
24 is on roll 20. Thus, the orientations are possible when
substantially the entire length of tape 24 is wound onto roll 20
and when the entire length of tape 24 has been unwound from roll 20
and only the core 22 of roll 20 remains. Specifically, dispenser 10
is movable between a first orientation where the dispenser is
supported on the surface 52 on front legs 26, 27 and a first region
of the roll of tape 20; and a second orientation where the
dispenser is supported on the surface 52 on the rear ends 12h, 14h
and a second region of the roll of tape 20. The first and second
orientations are substantially at right angles to each other and
therefore moving between the two orientations requires rotation of
dispenser 10 through about ninety degrees.
[0042] Thus, when the user no longer wishes to hold dispenser 10 in
one hand, they are able to place dispenser 10 on surface 52 in the
first orientation (FIG. 8).The first orientation is a generally
horizontally orientation. In this first orientation, dispenser 10
is in a standing position, ready for dispensing tape 24 therefrom,
and being supported on the pair of front legs 26, 27 and on a
portion of the substantially full roll of tape 20. It will be
understood that while front leg 27 is not illustrated in FIG. 8,
the dispenser rests on the tips 26a, 27a of the dispenser's two
front legs 26, 27. In particular and as is shown in FIG. 8, the
dispenser 10 rests on the forwardmost curved portion of tips 26a,
27a. When dispenser 10 is in this first orientation, cutter blade
50 is retained a distance away from surface 52 and is therefore in
a suitable position to be able to cut tape 24 withdrawn from roll
20. Since blade 50 angles downwardly toward surface 52, blade 50 is
in a relatively safe position for use. While dispenser 10 is
standing in this first orientation, the user may grasp the free end
24a of tape 24 and, holding the dispenser 10 down on surface 52
with their other hand, withdraw a desired length of tape 24 from
roll 20. When the desired length of tape 24 has been withdrawn, the
user will pull the tape upwardly and cut the same on blade 50. Once
a length of tape 24 has been cut, the free end 24a of tape 24 will
come to rest on tape rests 34, 35 and is therefore retained spaced
a distance above the surface 52. This both stops the free end 24a
from sticking to surface 52 but also positions the free end 24a in
a location where it is relatively easily grasped by the user for
dispensing of an additional length of tape 24.
[0043] As the tape 24 is withdrawn, the amount wound onto core 22
diminishes, thereby reducing the overall thickness of the tape 24
on core 22. This progressive reduction in tape thickness causes
dispenser 10 to rotate on the curved outer surface of tips 26b, 27b
of front legs 26, 27 in the direction of arrow "C" (FIG. 8). This
rotation is caused by a progressively different region of the
curved outer surface of tips 26a, 27a coming into contact with
surface 52. The progressive rotation is indicated by arrow "E" in
FIG. 8. FIG. 9 shows the tape dispenser 10 in the first orientation
but with the amount of tape 24 on core 22 substantially reduced and
a completely different region of tips 26a, 27a in contact with
surface 52. When flattened region 26b' is reached in the
progressive rotation of dispenser 10, the tendency to rotate is at
least somewhat reduced.
[0044] FIG. 10 shows tape dispenser 10 standing in the second
orientation on surface 52. The second orientation is a generally
vertical orientation. In this second orientation dispenser 10 rests
on surface 52 on rear legs 28, 29 and a second region of the
substantially full roll of tape 20. This second orientation
presents the tape rests 34, 35 in a far easier position for a
person to grasp the free end 24a of tape 24. It also makes blade 50
more visible to the user, thus increasing the safety level in using
the device. In the second orientation, tape dispenser 10
particularly rests on rear ends 12h, 14h and on the second region
of the substantially full roll of tape 20. When dispenser 10 is in
this second orientation, cutter blade 50 is retained a distance
away from surface 52 and is therefore in a suitable position to be
able to cut tape 24 withdrawn from roll 20. Additionally, the free
end 24a of tape 24 sits on tape rests 34, 35 and is therefore also
spaced a distance above the surface 52 and is therefore does not
stick on surface 52 and is relatively easily grasped by the user.
As tape 24 is withdrawn from roll 24, the amount of tape wound
around core 22 decreases and the thickness of tape 24 is reduced.
As this occurs, tape dispenser 10 tends to rotate in the direction
of arrow "F" (FIG. 10). This rotation motion is enabled because a
progressively new region of the curved outer surfaces of rear ends
12h, 14h is brought into contact with surface 52. Rear ends 12h,
14h tend to rotate in the direction of arrow "G" moving tips 29a,
28a downwardly toward surface 52. FIG. 11 shows the tape dispenser
10 standing on surface 52 in the second orientation but with the
quantity of tape 24 on core 22 greatly reduced. Tape dispenser 10
is still situated in a position where free end 24a of tape 24 is
presented in a suitable position for dispensing. When tips 27b, 29b
of rear legs 27, 29 contact surface 52, rotation about rear ends
12h, 14h substantially ceases.
[0045] It will be noted that, initially, when tape dispenser 10 is
in the first orientation and the roll 20 is full of tape 24, the
distance between the tips 26a, 27a and the contact point of the
first region of tape 24 with surface 52 is relatively short. This
distance is indicated by the line "X1" in FIG. 8. When the
dispenser 10 is still in the first orientation and the roll 20 has
less tape 24 thereon, then the distance between the tips 26a, 27a
and the contact point of the first region of tape 24 with surface
52 is longer and is indicated by the line "X2" in FIG. 9.
Obviously, the distance between tips 26a, 27a and the contact point
increases gradually from the initial distance "X1" to the distance
"X2", and then to the final distance (not shown) between tips 26a,
27a and the contact point of core 22 on surface 52 when all of the
tape has been withdrawn from roll 20.
[0046] Similarly, when dispenser 10 in is the second orientation
and the tape roll 20 is full, the distance between rear ends 12h,
14h and the contact point of the second region of tape 24 on
surface 52 is relatively small and is indicated by the reference
number "X3" in FIG. 10. As the amount of tape 24 is reduced on roll
24, the distance between rear ends 12h, 14h and the contact point
of the second region of tape 24 on surface 52 increases and is
indicated by reference number "X4" in FIG. 11. Similarly, the
distance between rear ends 12h, 14h and the contact point increases
gradually from the initial distance "X3" to the distance "X4", and
then to the final distance (not shown) between rear ends 12h, 14h
and the contact point of core 22 on surface 52 when all of the tape
has been withdrawn from roll 20.
[0047] Because the two front legs 26, 27 and the two rear legs 28,
29 are spaced laterally from each other, and are spaced a distance
longitudinally from the contact point (first or second region) of
the tape roll 20 on surface 52, tape dispenser 10 remains stable at
all times during dispensing of tape 24 therefrom. Additionally,
when tape dispenser 10 is in either of the first and second
orientations on surface 52, the cutter blade 50 is kept, at all
times, a suitable distance away from the surface 52 upon which
dispenser 10 rests and is therefore available to cut tape 24
dispensed from roll 20 in a safe fashion.
[0048] In the foregoing description, certain terms have been used
for brevity, clearness, and understanding. No unnecessary
limitations are to be implied therefrom beyond the requirement of
the prior art because such terms are used for descriptive purposes
and are intended to be broadly construed.
[0049] Moreover, the description and illustration of the invention
are an example and the invention is not limited to the exact
details shown or described.
