HOLDER FOR TAPE DISPENSERS
Abstract
A holder for a tape dispenser includes a base which is engaged
with suction cups for securing the base and holder to a supporting
surface. In one embodiment the base supports a dispenser seat which
in turn has a retaining arm projecting outwardly from it and then
doubling back over the seat. The retaining arm fits through a
hollow spindle on the dispenser and holds the dispenser against the
seat. In other embodiments the base also supports a dispenser seat,
and the seat has a pair of walls extending upwardly from it. The
dispenser is clamped between the walls. Thus tape can be withdrawn
from the dispensers with only one hand. In every embodiment the
base is detachable from the suction cups to facilitate installation
of the dispenser in the holder.

Description
BACKGROUND OF THE INVENTION
This invention relates to holding devices and more particularly to
holders for tape dispensers.
Much of the cellophane tape currently marketed for household and
office use is supplied in rolls contained in dispensers. These
dispensers each provide a journal for the tape roll as tape is
withdrawn from it, and furthermore each has a serrated cutting edge
located beyond the tape roll for severing the tape withdrawn across
it. Normally, the dispensers are injection molded from suitable
plastic resins and their tape rolls are permanently attached to
them. Consequently, they are disposable. Some, however, are
reloadable.
Since the tape dispensers of current manufacture are molded from
plastic in relatively small sizes, two hands are required to
withdraw tape from them. In particular, one hand is used to hold
the roll, while the other is used to grasp the tape. This presents
difficulties where one does not always have two hands available for
withdrawing tape. For example, when wrapping packages, one hand is
normally used to hold the wrapping on the package while the other
is used to apply the tape.
SUMMARY OF THE INVENTION
One of the principal objects of the present invention is to provide
a holder which will hold a tape dispenser relatively rigid with
respect to a firm supporting surface such as a table top so that
tape can be withdrawn from the dispenser with only one hand.
Another object is to provide a dispenser of the type stated which
is easily are securely attached to a supporting surface without
damaging the surface or injuring its finish. A further object is to
provide holders of the type stated which are easily and
conveniently engaged with tape dispensers of current manufacture.
An additional object is to provide a holder of the type stated
which is reusable. Still another object is to provide holders of
the type stated which are attractive in appearance, rugged in
construction, and easy to manufacture. These and other objects and
advantages will become apparent hereinafter.
The present invention is embodied in a holder having a base which
engages suction cups for retaining it on a supporting surface. The
base supports means for engaging and holding a tape dispenser. The
invention also consists in the parts and in the arrangements and
combinations of parts hereinafter described and claimed.

DETAILED DESCRIPTION
Referring now to the drawings (FIGS. 1-4), 2 designates a tape
dispenser containing a roll of tape 4 which is wound about a spool
6. The dispenser 2 is normally injection molded from plastic as an
integral unit and includes a side wall 8 and a peripheral wall 10
merged into the side wall 8. The peripheral wall 10 curves around
and shields a substantial portion of the tape roll 4, and
furthermore along the bottom of the dispenser 2 it is substantially
flat, thereby forming a base 12 (FIG. 4) upon which the dispenser 2
rests. Generally, at the center of curvature for the curved portion
of the peripheral wall 10 the side wall 8 is provided with an
integrally formed hollow spindle 14 (FIGS. 1 and 4) which projects
in the same direction away from the side wall 8 as does the
peripheral wall 10 and forms a laterally opening socket 15 in the
side wall 8. The spindle 14 further provides a journal for the
spool 6 on which the roll of tape 4 is wound, and the unattached
end of the spool 6 has radially directed tabs 16 (FIG. 4) for
retaining the spool 6 permanently on the spindle 14. Beyond the
curved section of the peripheral wall 10 both the side wall 8 and
the peripheral wall 10 project away from the tape roll 4 in the
formation of a cutter 18 having a generally flat upwardly presented
surface 20 across which the tape 4 is withdrawn. When the tape 4 is
not being withdrawn from the tape roll 4 the leader extending from
that roll is pressed against and adheres the surface 20. The side
wall 8 between the surface 18 and the spindle 14 has an upwardly
presented arcuate margin 22 which curves downwardly below the
surface 20 and the spindle 14. Likewise, the curved margin 22 drops
below the leader withdrawn from the roll of tape 4 to enable one to
conveniently grasp the leader and withdraw still more tape 4. On
the opposite side of the upwardly presented surface 20 the cutter
18 is provided with a serrated cutting edge 24 for severing the
segment of tape 4 withdrawn beyond it. The side of the dispenser 2
located opposite from the side wall 8 may be open or it may be
covered by a sheet of cardboard which fits around the spindle 14
and is held in place by the radial tabs 16. The cardboard may and
usually does have printed matter upon it. The tape dispenser 2 is
conventional and is marketed by the 3M Company in conjunction with
their Scotch Brand tape. Sears Roebuck & Company markets its
private brand tape in a very similar holder.
To secure the tape dispenser 2 to a supporting surface such as the
top of a desk or the side of a filing cabinet, the dispenser 2 is
fitted into a holder 30 which in turn is secured to the supporting
surface. The holder 30 is preferably formed from plastic having a
limited amount of resiliency and includes a flat base 32 provided
with forward and rear cutouts 34 and 36 (FIG. 2). The forward
cutout 34 is U-shaped and opens outwardly from the forward edge of
the base 32. Its U-shaped edge possess a substantially full
downward bevel (FIGS. 1 and 3) so that it is wider on the lower
surface of the base 32 than it is on the upper surface of the base
32. The rear cutout 36 is disposed behind the cutout 34 and
includes an elongated U-shaped portion 38 which extends in the same
direction as the cutout 34 and a short lateral portion 40 which
opens outwardly through the side of the base 32. The edges of the
elongated portion 38 and lateral portion 40 are also provided with
a substantially full bevel so that they are spaced further apart on
the bottom of the base 32 than on the top of the base 32.
The base 32 at its cutouts 34 and 36 is engaged with suction cups
42 for attaching the holder 2 to and supporting it on a supporting
surface. More specifically, each suction cup 42 is formed from an
elastomeric material and includes an outwardly flared portion 44
which is pressed against the supporting surface so that air is
excluded from its dish-shaped interior. When the flared portion 44
attempts to revert back to its original shape due to its own
resiliency a partial vacuum is created within the dish-shaped
interior so that the pressure exerted by the surrounding air holds
the suction cup 42 against the supporting surface. The cup 42 is
further provided with a mounting boss 46 which projects axially
from the outwardly flared portion 44 and has a laterally opening
annular groove 48 located adjacent to the outwardly presented
surface of the flared portion 44. The width of the boss 46 at the
groove 48 is approximately the same as the width of cutouts 34 and
36 measured at their narrowest points, that is along the upper
surface of the base 32, while the bevel of the cutout margins
generally conforms to the bevel or taper of the flared portion 44
when that flared portion is pressed against the supporting surface
(FIG. 3). Accordingly, the boss 46 will fit into either of the
cutouts 34 or 36 and when so fitted the upper or enlarged end of
the boss will overlie the top surface of the base 32 around the
cutouts 34 or 36 and will prevent the holder 30 from being
withdrawn from the suction cups 42. Moreover, the beveled surface
defining the cutouts 34 or 36 will engage the tapered or flared
surface of the flared portion 44 so that a firm support is provided
for the base 32 thus preventing the base 32 from rocking back and
forth to any appreciable extent when engaged with the suction cups
42.
Two suction cups 42 are employed and these are pressed against the
supporting surface with the peripheral margins of their outwardly
flared portions 44 touching but not overlapping (FIGS. 2 and 4). In
this connection, it should be noted that the spacing between the
U-shaped ends of the cutouts equals the spacing between the bosses
46 on the suction cups 42 when the cups are emplaced in the
foregoing manner. Moreover, the distance between the forward edge
of the base 42 and the forwardmost edge of the lateral portion 40
in the rear cutout 36 is slightly less than the spacing between the
bosses 46 measured from within their laterally opening grooves
48.
To engage the base 32 with the suction cups 42 emplaced with their
peripheries touching as previously described, the lateral portion
40 of the rear cutout 36 is aligned with the laterally opening
groove 48 in the boss 46 of the rear suction cup 42. Then the base
32 is advanced across the flared portions 44 of both suction cups
42 until the boss 46 on the rear suction cup 42 is in the elongated
portion 38 of the cutout 36 and the boss 46 of the forward suction
cup 42 aligns with the end of the forward groove 36. At this time
the holder 30 is shifted forwardly, causing the base 32 to advance
across the flared or cup-shaped portions 44 of the cups 42. Since
the spacing between the sides of the respective cutouts 34 and 36
is less than the width of the upper enlarged ends of the bosses 46,
the upper enlarged ends will overlie the upper surface of the base
32. In other words, the edges of the cutouts 34 and 36 engage and
retain the suction cups 42 at the annular grooves 48 therein. When
the U-shaped ends of the cutouts 34 and 36 engage the bosses 46 of
the two suction cups 42, the base 32 cannot be moved laterally or
forwardly, not can it be withdrawn upwardly.
While one of the side edges of the base 32 is free to enable the
lateral portions 40 for the rear cutout 36 to open outwardly, the
opposite side edge merges into the side of a flat dispenser seat 50
(FIGS. 1 and 4) which is positioned directly above and spaced from
the base 32. The opposite side of the seat 50 in turn merges into a
rearwardly presented retainer arm 52 and a forwardly disposed side
wall 54. The retainer arm 52 curves outwardly away from the seat 50
and then doubles back upon itself, terminating in a tongue 56 which
extends transversely across the seat 50 and is inclined downwardly
at a slight angle thereto. The spacing between the tongue 56 and
the seat 50 is slightly less than the distance between the lower
arcuate margin of the socket 15 and the flat base 12 on the
dispenser 2. The tongue 56 is furthermore not presented
perpendicularly to the longitudinal axis of the seat 50, but is
instead canted slightly with respect to that axis. The side wall
54, on the other hand, is presented generally perpendicular to the
seat 50 and terminates at a short retainer tab 58 which projects
over the seat 50. The longitudinal distance between the tongue 56
and the tab 58 generally equals the spacing between the socket 15
and the lowest point on the arcuate margin 22 of the dispenser 2,
whereas the vertical spacing between the tab 58 and the seat 50 is
slightly greater than the vertical distance between the lowest
point of the arcuate margin 22 and the flat base 12 on the
dispenser 2.
The dispenser 2 is installed in the holder 30 by positioning the
side wall 8 of the dispenser 2 opposite to the arm 52 and side wall
54 of the holder 30 and aligning the dispenser socket 15 with the
tongue 56 on the end of the retainer arm 52. Thereupon, the holder
30 and dispenser 2 are brought together, in which case the tongue
56 will enter the socket 15 and the flat base 12 of the dispenser 2
will pass across the flat seat 50 of the holder 30, provided of
course the entire dispenser 2 is raised slightly against the
resiliency of the arm 52 to enable the base 12 to rise to the upper
surface of the seat 50. Actually the tongue 56 engages the
cylindrical interior surface of the socket 15 at two spaced cutout
points located along the bottom portion of that surface. When the
side wall 8 of the dispenser 2 approaches the side wall 54 of the
holder 30 the retainer tab 58 will project over the arcuate margin
22 of the side wall 8. The tongue 56 on the retaining arm 52 will,
of course, press the dispenser 2 firmly against the seat 50, and
moreover by reason of the fact that it is canted slightly it will
cock the dispenser 2 slightly on the seat 50, that is, it will urge
the dispenser side wall 8 against the holder side wall 54. The
retaining tab 58 further stabilizes the dispenser 2 on the holder
30.
Once the dispenser 2 is fitted into the holder 30, tape 4 may be
withdrawn from the dispenser 2 with the use of only one hand. In
particular the leader of tape 4, that is the portion extending
between the tape roll and the upwardly presented surface 20 is
lifted off of the surface 20 and pulled away from the dispenser 2
until the desired length of tape projects beyond the serrated
cutting edge 24. As the tape 4 is pulled away from the dispenser 2
the U-shaped ends of the cutouts 34 and 36 bear against the bosses
46 on the suction cups 42 and prevent the base 32 from disengaging
or sliding relative to the suction cups 42. Once the desired length
of tape 4 has been withdrawn past the serrated cutting edge 24 the
withdrawn tape 4 is urged downwardly against the cutting edge 24,
the force being applied from one side of the tape 4 to the other so
as to sever the tape 4 along the serrated edge 24. The holder 30
does not cover the arcuate margin 22 to any significant extent and
consequently access to the tape leader is still possible from
either side of the dispenser 2 so that either hand can be used to
withdraw the tape 4. The open ended cutouts 34 and 36 enable the
holder 30 to be detached from its suction cups 42 to facilitate
fitting tape dispensers 2 to that holder 30.
Smaller tape dispensers 62 (FIGS. 5 and 7), which are similar in
shape to the dispenser 2 but smaller in size, may also be installed
on and retained by the holder 30, provided an adapter 64 is used.
The adapter 64 includes (FIGS. 5-7) a top wall 66, a bottom wall
68, and a connecting portion 70 interconnecting the top and bottom
walls 66 and 68. The spacing between the top and bottom walls is
such that the adapter 64 will receive flat base 12 of the
peripheral wall 10 on the smaller tape dispenser 62 so that the
wall 66 overlies the flat base, while the bottom wall 68 underlies
it. In most small dispensers 62 a short rib or tab 72 projects
laterally and then upwardly from the edge of the flat base 12 on
the peripheral wall for the purpose of holding a cardboard insert
bearing printed material. To accommodate this rib 72 the bottom
wall 68 is provided with a groove 74 which leads up to a cutout in
the connecting portion 70. Accordingly, the connecting portion 70
seats against the side edge of the flat base 12. The thickness of
the bottom wall 68 is such that it elevates the socket 15 of the
small dispenser 62 to a position where it aligns with and receives
the tongue 56 of the holder 30 when the bottom wall 68 rests upon
the seat 30. In such an instance the arcuate margin 22 of the
dispenser 62 is positioned directly below the retainer tab 58
also.
It is possible to provide a modified holder 80 (FIGS. 8-11) for a
similar tape dispenser 82. Like the dispenser 2, the dispenser 82
includes a side wall 84 provided with a hollow spindle 86 which
forms a socket 88 opening out of the side wall 84. The spindle 86
furthermore forms a journal for a spool 90 (FIG. 11) around which
tape 92 is wound. At its end opposite from the side wall 84 the
spindle 86 is provided with radially projecting tabs 94 for
retaining the spool 90 on the spindle 86. The side wall 84 along
most of its periphery merges into a peripheral wall 96, and both
the side wall 84 and the peripheral wall 96 project away from the
roll of tape 92, forming a cutter 98 having a serrated cutting edge
100 and an arcuate upper margin 102. Along the bottom of the cutter
98 and beneath the roll of tape 92 the peripheral wall 96 is flat
and forms a flat base 104 for the dispenser 82. The dispenser 82 is
conventional and is marketed by LePages, Inc. of Pittsburgh,
Pennsylvania, under the trademark LePages.
The holder 80 includes a base 106 provided with a pair of bayonet
cutouts or slots 108 which are adapted to engage the suction cups
42. In particular, each bayonet slot 108 includes a generally
circular portion 110 and an elongated portion 112 extending
rearwardly from the circular portion 110. The elongated portion 112
terminates at a U-shaped margin and is approximately the same width
as the suction cup boss 46 at the groove 48 therein, but is
narrower than the enlarged portion of the boss 46 disposed above
the groove 48. The circular portion 110, on the other hand, is
large enough to receive the enlarged upper portion of the boss 46.
Moreover, with the exception of a short segment of the circular
portion located generally opposite to the U-shaped end of the
elongated portion 112, the edge of each bayonet slot 108 is
provided with substantially a full bevel (FIG. 10), the taper of
which spreads downwardly and generally conforms with the taper of
the flared portion 44 on the suction cup 42 when the cup 42 is
engaged with the supporting surface. This enables the beveled edges
of the slot 108 to enter the groove 48 in the boss 46. The short
segment of the circular portion 110 located opposite to the
U-shaped end of the elongated portion 112 is provided with a slight
bevel, but that bevel is not great enough to enable the edge of the
slot 108 to enter the groove 48 in the suction cup boss 46.
The spacing between the circular portions 110 of the two slots 108
equals the spacing between the bosses 46 on the suction cups 46
when the flared portions 44 touch at their peripheries but do not
overlap. Accordingly, the circular portions 110 of the two slots
108 will align with the bosses 46 of the two suction cups 42 so
that those bosses will enter the slots 108 simultaneously. Once the
bosses 46 are in the circular portions 110 of slots 108 the holder
80 is shifted forwardly and this brings elongated portions 112 of
the slots 108 around the bosses 46. Stated differently, as the
holder base 106 shifts forwardly the side margins along the
elongated portions of the bayonet slots 108 enter the laterally
opening grooves in the bosses 46, and the forward advancement
continues until the U-shaped end margins of the elongated portions
112 also enter the grooves 48. When the bosses 46 are so disposed
in the bayonet slots 108, the holder 80 cannot be withdrawn
upwardly, nor can it be moved laterally or forwardly.
The holder 80 can, of course, be removed from the suction cups 42
by the reverse of the previously described procedure and when it is
moved forwardly to bring the bosses into the circular portions 110
of the bayonet slots 108 it is significant to note that the absence
of a full bevel along the segments of the circular portions located
opposite to the U-shaped ends of the elongated portion 112 prevents
that edge of the base 106 from engaging the grooves 48 in the
bosses 46 and preventing the removal of the bosses 46 from the
bayonet slots 108.
At its ends the base 106 turns upwardly and merges into a dispenser
seat 114 which is spaced from the base 106, but nevertheless
overlies it. The dispenser seat 114 is slightly wider than the
dispenser 82 and along its sides it merges into a pair of side
walls 116 and 118 which extend upwardly and converge slightly. The
spacing between the upper ends of the side walls 116 and 118 and
the seat 114 is somewhat greater than the spacing between the
lowest part of the socket 88 and the flat base 106 on the holder
80. At its upper end the side wall 116 is provided with an
indentation 120 which projects into the socket 88. Moreover, the
spacing between the upper ends of the walls 116 and 118 when those
walls are unrestrained is slightly less than the thickness of the
dispenser 82 at the spindle 86 so that the dispenser 2 can be
clamped between the walls 116 and 118. Finally, it should be noted
that the upper ends of the walls 116 and 118 flare slightly
outwardly in the formation of lips 124.
The tape dispenser 82 is engaged with the holder 80 by forcing the
dispenser 82 downwardly between the side walls 116 and 118 of the
holder 80. When the lower end of the dispenser 82 initially engages
the side walls 116 and 118 it does so at the outwardly flared lips
124 since the walls 116 and 118 are spaced apart a distance
slightly less than the width of the dispenser 80. Consequently, as
the dispenser 82 is forced downwardly toward the seat 114 it
spreads the side walls 116 and 118, and this enables the side walls
116 and 118 to maintain a tight grip on the dispenser 82. Moreover,
when the flat base 102 of the dispenser 82 seats against the seat
114 of the holder the indentation 120 will project into the socket
88 of the spindle 86 and further stabilize the dispenser 82 on the
holder 80.
The tape dispenser 82 when installed in the holder 80 is used in
the same manner as the tape dispenser 2 when that dispenser is
retained by its holder 30. To prevent the holder 80 from tipping
too far forwardly, its base 106 may be provided with a short bumper
122 immediately in front of the forward suction cup 42. The
thickness of this bumper 122 should be equal to or slightly less
than the height of the flared portion 44 on the suction cup 142
when that portion is pressed against the supporting surface.
It is possible to provide another modified holder 130 (FIG. 12)
which is also suitable for holding the tape dispenser 82. The
holder 130 is provided with a base 132 having bayonet cutouts or
slots 134 for engaging the bosses 46 on the suction cups 42. For
all intents and purposes the base 132 is identical to the base 106
of the holder 80, and accordingly it will not be discussed in
further detail.
At its end the base 132 merges into a dispenser seat 136 which is
spaced from and directly overlies the base 132. Along its sides the
dispenser seat 136 merges into a pair of upwardly projecting side
walls 138 and 140 which converge slightly, and the upper end of the
side wall 140 flares outwardly in the provision of a lip 142.
Moreover, the distance between the upper end of the side wall 140
and the seat 136 exceeds the distance between the flat base 104 on
the dispenser 82 and the lower portion of the dispenser spindle 86.
On the other hand, the side wall 138 is provided with forward and
rear tabs 144 and 146, respectively, both of which turn in
initially and thereafter double back upon themselves so as to
project outwardly beyond the outer surface of the side wall 138.
The distance between the inwardly turned portion of the forward tab
144 and the seat 136 is slightly greater than the distance between
the lowest point on the arcuate margin 102 of the tape dispenser 82
and the flat base 104 thereof. The distance between the inwardly
turned portion of the rear tab 146 and the seat 114 is generally
equal to the distance between the lowermost portion of the socket
88 and the flat base 102. Finally, the longitudinal spacing between
the forward and rear tabs 144 and 146 is approximately equal to the
distance between the center of the socket 86 and the lowest point
along the arcuate margin 102.
When the tape dispenser 82 is forced downwardly between the side
walls 138 and 140 it will cam those walls apart due to the presence
of the outwardly flared lip 142 on the side wall 140 and the
outwardly directed tabs 134 and 146 on the side wall 138. Since the
walls 136 and 138 converge they will tightly grip the dispenser 82
as it is urged downwardly. In this connection, the side wall 140
engages the dispenser 82 at the radially projecting tabs 94 on the
end of its spindle 86. When the flat base 102 of the dispenser 82
comes to rest against the seat 136 of the holder 130 the forward
tab 144 will project over the arcuate margin 102 and the rear tab
146 will project into the socket 88. The foregoing disposition of
the tabs 144 and 146 further restrains withdrawal of the dispenser
82 from the holder 130 and in addition prevents the dispenser 82
from shifting longitudinally with respect to the holder 130.
The cutter 98, of course, projects outwardly beyond the forward
margins of the side walls 138 and 140 so that one can reach behind
the cutter 98 and grip the tape leader. The tape 92 is withdrawn
from the dispenser 82 when that dispenser is retained by the holder
130 in the same manner as when the dispenser 82 is retained by the
holder 80.
It is possible to provide still another holder 150 (FIGS. 13 and
14) which is very similar to the holder 30, 80 and 130, but is
configured to retain a slightly different tape dispenser 152. The
dispenser 152 includes a pair of side walls 154 which are connected
along their front and rear margins by front and rear walls 156 and
158, respectively. Near the rear wall 158 a roll of tape 160 is
journaled between the side walls 154. Forwardly beyond the roll of
tape 160 the side walls 154 and the front wall 156 are configured
to form a cutter 62 having a serrated cutting edge 164. The side
walls 154 are continuous and uninterrupted, and the front wall 156
is positioned at an oblique angle with respect to the bottom
margins of the side walls 154. The dispenser 152 is distributed by
the Technical Tape Corporation of New Rochelle, New York, under the
trademark Tuck, and does not have a bottom wall or flat base, but
instead its bottom is completely open.
The holder 150 includes a base 170 which is provided with bayonet
slots 172 for receiving the bosses 46 on the suction cups 42. The
base 170 for all intents and purposes is identical to the base 106
of the holder 80, and accordingly it will not be described in
further detail.
At its ends the base 170 merges into a seat 174 which is spaced
from and disposed directly above the base 170. Along its side
margins the dispenser seat 174 merges into a pair of side walls 176
and 178 which slightly converge and are flared slightly outwardly
at their upper ends. The spacing between the upper ends of the side
walls 176 and 178 when such walls are unrestrained is slightly less
than the spacing between the side walls 154 on the dispenser 152.
The forward end of the side wall 176 projects beyond the forward
margin of the side wall 178 and forms a retention arm 180 having an
inwardly projecting tab 182. The angle between the tab 182 and the
dispenser seat 174 is approximately equal to the angle between the
front wall 156 and the bottom margins of the side walls 154 on the
tape dispenser 152. Finally, it should be noted that the side walls
176 and 178 extend no higher than the portion of the dispenser side
walls 154 between the cutter 162 and roll of tape 160.
Finally, the base 170 of the holder 150 is provided with a bumper
184 located in front of the forward suction cup 42, and a pair of
laterally extending arms 186 which turn downwardly at their ends
and engage the supporting surface, just as does the bumper 184. The
bumper 184 and arms 186 further stabilize the holder 150 as tape
160 is withdrawn from the dispenser 152.
To install the dispenser 152 in the holder 150, the former is
forced downwardly between the side walls 176 and 178 of the latter.
This causes the side walls 176 and 178 to spread and grip or clamp
the dispenser 152 along its side walls 154. Once the lower margins
of the side walls 154 on the dispenser 152 engage the seat 174 of
the holder 150 the entire dispenser 152 is shifted forwardly until
its front wall 156 engages the stop tab 182.
Tape 160 is withdrawn from the dispenser 152 similar to the manner
in which tape is withdrawn from the dispensers 2 and 82. Any
tendency of the dispenser 152 to slide forwardly in the holder 150
as tape is pulled from it is resisted by the stop tab 182.
In the descriptions of the various embodiments of the holder the
seats on which the dispensers rest and the bases have been
described as different components. Actually, in each embodiment the
seat and base are formed integral and the combination of the two
may be referred to simply as a base.
This invention is intended to cover all changes and modifications
of the example of the invention herein chosen for purposes of the
disclosure which do not constitute departures from the spirit and
scope of the invention.
