Roll holder and dispenser for paper products
Abstract
A roll holder and dispenser having a base, a roll-receiving
tube, and a handle securable in an end of the tube. The handle has
two caps or buttons. Pressing one of the buttons allows the handle
to be removed from the tube by causing a plunger in the handle to
rotate so that prongs securing the handle to the tube are pressed
into recesses in the plunger when the handle is pulled out of the
tube. Pressing the other button moves arms into contact with the
roll of paper products to restrain the movement or rotation of the
roll. The buttons are spring biased so they return to their
original positions when they are released. The base of the roll
holder houses a suction device that permits the roll holder to be
adhered to a countertop or other surface by moving a handle in a
slot in the base.

FIELD OF INVENTION
[0002] This invention relates generally to a roll holder and
dispenser for a roll of paper products.
BACKGROUND OF INVENTION
[0003] Many products are stored on rolls, including paper towels
and tissue paper. Most devices that hold and dispense these rolls
make it difficult for a person to change a roll or do not keep the
roll from falling off the device. Further, many of these devices
lack the ability to selectively restrain a roll's rotation and are
often difficult to attach to an adjacent surface, such as a
countertop, cabinet, refrigerator, etc.
[0004] For example, the paper roll may slide up on the roll holder
if an individual paper section is pulled upward. If the upward
pulling is not timely corrected, the roll may be pulled off the
roll holder, or the roll holder may tip or fall over. A cap or
handle may be installed on the top of the roll holder to prevent
the paper roll from coming off the holder; however, the use of such
handles increases the likelihood that the roll holder will tip or
fall if the paper hangs up on the holder. Moreover, such handles
can often be difficult to install on the roll holder.
[0005] Another problem with many roll holders is that they have no
means to stop the movement of the roll of paper when individual
towels are being removed from the roll. Thus, it is very difficult
to tear off a sheet of paper towel without holding the roll, and
several sheets may inadvertently unroll when the end of the towel
roll is pulled. In such cases, the excess towel segments must be
placed back on the roll, but twisting the roll in reverse. Some
towel holders have a means to stop the movement of the paper towel,
but these means require a gripping action on the roll of the
holder. If a user's hands are messy or dirty, the towel holder or
roll will also get dirty. Another method of attempting to solve
this problem is to make the rotation of the towel more difficult,
so that that each towel tears at a perforation; this, however,
means that only one sheet can be torn off at a time.
SUMMARY OF INVENTION
[0006] The roll holder of the invention has an easy to install cap
or handle that latches inside the tube or spindle of the roll
holder, provides means in the handle to prevent the paper roll from
rotating when individual towels are being removed from the roll,
and a suction device to the holder securely on the counter or work
surface.
[0007] The roll holder and dispenser of the invention comprises a
tube attached to and upstanding from a base. An end cap is inserted
into the top of the tube, and a handle assembly is inserted into
the end cap. Prongs extend downward from the handle. The prongs
have catches that lodge under a projection of the end cap. Behind
each of the prongs is a longitudinal rib that it part of the
plunger. The ribs prevent the prongs from moving inward and the
catches disengaging. A unifying piece in the handle has downward
extending arms that may be lodged inside the cardboard cylinder
around which the towels or paper products are rolled to prevent the
roll from rotating when a desired number of towel or paper segments
have been unrolled from the holder.
[0008] The top of the handle has inner and outer concentric caps or
buttons. Pressing on the inner cap or button causes a spring biased
plunger in the handle to rotate. As the plunger rotates,
longitudinal ribs are moved out of the way of the prongs, allowing
them to flex backwards when the handle is pulled out of the tube.
When the inner cap is released, the spring biased plunger rotates
in the opposite direction, and the longitudinal ribs move back in
place behind the prongs so that they cannot move out of place, thus
securing the handle in the top end of the tube. The spring
automatically returns the plunger, the prongs, and the catches on
the prongs to their original positions in the handle.
[0009] The outer cap is biased by a separate spring housed in the
handle assembly. When the outer cap or button is pressed, it, in
turn, presses on the unifying piece, causing the unifying piece to
move downward. As the unifying piece moves downward, its downward
extending arms either make contact with the top of the roll of
paper products or lodge in the paper cylinder in the center of the
roll of paper products; in either case, the rotation of the paper
roll is restrained, preventing roll from rotating. Release of the
outer cap retracts the arms and allows the paper roll to rotate.
The spring automatically returns the unifying piece and its arms to
their original positions in the handle.
[0010] The base of the roll holder houses a suction device. The
suction device comprises a suction pad, a pivot, a handle, and a
plate with upstanding bridge-like structures with sloped
undersides. The suction plate is attached to a central portion of
the suction pad, and an outer portion of the suction pad is in
contact with the counter or work surface to which the suction
device is to be adhered. The handle extends from the sloped
underside of one of the bridge-like structures, through the center
of the pivot, along the sloped underside of the other bridge-like
structure, and out through an elongated slot in a side of the base.
The handle is positioned so that it is in sliding contact with the
sloped undersides of the bridge like structures.
[0011] When the handle of the suction device is moved in one
direction in the elongated slot, it slides along the sloped
undersides of the bridge-like structures and pulls the plate (and
the central portion of the suction pad) away from the counter or
work surface to which the suction device is to be adhered. As the
central portion of the suction pad is moved away from the counter,
a partial vacuum is created between the central portion of the
suction pad and the counter, causing the outer portion of the
suction pad to adhere to the counter and preventing the roll holder
from being moved or tipped. When the handle is moved in the
opposite direction in the elongated slot, the central portion of
the suction pad is moved toward the counter, relieving the partial
vacuum, and permitting the towel holder to be moved to a different
location on the counter.

housing 14 are adjacent and spaced around the outer surface of the
lower end 41 of the plunger 18, as shown in FIGS. 4, 7, and 8.
[0051] As shown in FIGS. 4, 5, and 6, the bar or rod 32 of the
outer cap or button 16 is placed in the curved or angled channels
43 of the upper end 40 of the plunger 18. The outer cap or button
16 is moved downward until the lower end 34 of the outer cap outer
side 30 is in contact with the top of the outward extending arms 51
of the unifying piece 20 as shown in FIGS. 6 and 18, at which point
the outer cap 16 and the unifying piece 20 snap together when the
tab 35a of the side 30 of outer cap 16 fits or snaps into the
indentation 48b in the upper rim 48a of the unifying piece 20, as
shown in FIG. 18. (Also see indentation 48b in FIG. 19.)
[0052] As shown in FIGS. 4, 6, and 18, the inner cap or button 17
is placed in the outer cap hole 31 such that the catches 39 of the
inner cap prongs 38 are immediately under and in contact with the
edges 33 of the outer cap 16, as shown in FIG. 18.
Operation of Handle
[0053] The handle 6 is operated by pressing on the inner button or
cap 17 or the outer button or cap 16. The default positions of the
inner and outer buttons 17 and 16 are shown in FIG. 4. In the
default position, neither the upper spring 19 nor the lower spring
21 is compressed. In the default position, the rod or bar 32 of the
outer cap 16 is fully received in and at the bottom of the curved
or angled channels 43 of the plunger 18
[0054] In order to place a roll 2 of paper towels or other products
on the holder 1, the handle assembly 6 must be removed from the
tube upper end 8. The handle 6 is removed by first pressing
downward on the inner cap or button 17, as shown in FIG. 6.
[0055] As the inner cap 17 is pressed downward, the plunger 18 is
also forced downward by the force of the inner cap 17 on the upper
end 40 of the plunger 18. As shown in FIG. 6, as the inner cap 17
is pressed, the ledges 45 of the seats 44 of the plunger 18 press
downward on the upper end 47 of the upper spring 19, which causes
the upper spring 19 to compress and, apart from the pressing force,
bias the plunger 18 in the raised position, even though the plunger
18 is in the down or pressed position.
[0056] As the inner cap 17 and plunger 18 are pressed downward, the
curved or angled channels 43 in the upper end 40 of the plunger 18
move slidingly downward along the bar or rod 32 of the outer cap
16. (The outer cap 16, as well as its bar 32, remain stationary
during the downward movement of the plunger 18.) Since the channels
43 in the upper end 40 of the plunger 18 are curved, the sliding
movement of the bar 32 in the curved channels 43 causes the plunger
18 to rotate.
[0057] As the plunger 18 rotates, the recesses 42 in the plunger 18
also rotate, and as the recesses 42 rotate, the prongs 25 of the
housing are positioned over the recesses 42 so that when the handle
6 is pulled out of the upper end 8 of the tube 3, the prongs 25 can
be pressed inward into the recesses 42 as shown in FIG. 8, thus
disengaging the catches 26 of the prongs 25 of the housing 14 from
the protrusion or edge 12 at the lower end 11 of the end cap 4.
(See FIG. 4) (FIG. 7 shows the prongs 24 on the surface of the
plunger 18, which is their normal or default position--i.e., when
the inner cap 17 has not been pressed and the plunger 18 has not
been rotated.) As the handle 6 is pulled out of the tube 3, the top
face of the catches 26 (which are angled as shown in FIGS. 3 and 6)
slides against the bottom edge 12 of the end cap 4, thus bending
the prongs 25 inward so that the handle 6 may be removed in its
entirety from the upper end 8 of the tube 3.
[0058] When the handle assembly 6 is removed from the tube 3 of the
roll holder 1, the downward pressing or force on the inner cap or
button 17 may be released. When the pressing force on the inner cap
17 is released, the upper spring 19 forces the plunger 18 upward
via the force or bias of the upper end 47 of the upper spring 19 on
the ledges 45 of the seats 44 of the plunger. As the plunger 18 is
forced upward by the upper spring 19, the curved channels 43 of the
upper end 40 of the plunder 18 slide along the rod 32 of the outer
cap 16, and the plunger 18 rotates in the opposite direction. The
prongs 25 are thus positioned so that the catches 26 of the prongs
25 may again engage the protrusion or edge 12 at the lower end 11
of the end cap 4 when the handle 6 is inserted in the upper end 8
of the tube 3.
[0059] After the handle 6 is removed from the tube 3, a roll of
paper towels 2 may be installed on the tube 3 by placing the
opening in the cardboard cylinder (not shown) in the center of the
roll of paper towels 2 over the tube 3 such that the tube 3 is
fully inserted in the cardboard cylinder of the roll 2. In this
position, the roll of towels 2 rests on the top 55 of the base 5 of
the roll holder and dispenser 1, as shown in FIG. 2.
[0060] When the roll 2 of towels has been installed on the tube 3
of the roll dispenser 1, the handle assembly 6 may again be
inserted into the upper end 8 of the tube 3. As the handle 6 is
inserted into the upper end 8 of the tube 3, the inner cap 17 is
pressed (against the bias of the upper spring 19), causing the
plunger 18 to rotate until the recesses 42 of the plunger 18 are
aligned with the prongs 25 of the housing 14. This allows the
prongs 25 to be pressed inward into the recesses 42 as the handle
assembly 6 is pressed downward into the upper end 8 of the tube 3
and makes it possible for the handle 6 to be installed in the upper
end 8 of the tube 3 without resistance from the prongs 25 as they
slide against the protrusion or edge 12 at the lower end 11 of the
end cap 4. After the handle 6 is inserted back into the upper end 8
of the tube, the inner cap or button 17 is released and, due to the
bias of the upper spring 19, the prongs again engage the edge 12 of
the end cap 4 the notches 27 in the mid portion 24 of the housing
14 are meshed with, and cooperating with, the notches 13 in the
upper portion 10 of the end cap 4.
[0061] When the roll of towels 2 is so installed on the tube 3 and
the handle 6 is in place in the upper end 8 of the tube 3, the end
of the towel roll 2 may be pulled to unroll a towel from the roll
2. When an individual towel is exposed or extended from the roll 2,
it may be separated from the roll 2 by tearing it along the typical
perforations spaced at intervals along the roll of towels 2.
[0062] As an individual towel is pulled or unrolled from the roll
2, the roll 2 rotates around the tube 3. Additional individual
towels may be unrolled from the roll 2 by continuing to pull the
end of the exposed or unrolled individual towel. It is frequently
desirable, however, to prevent the roll of towels 2 from rotating
or continuing to rotate around the tube 3. If the towel roll 2 is
prevented from rotating, is easier to separate an individual towel
from the roll 2 at the perforation and impossible to inadvertently
unroll too many individual towels from the roll 2.
[0063] In order to prevent the towel roll 2 from continuing to
rotate around the tube 3 when towels are being dispensed from the
roll holder and dispenser 1, the outer cap or button 16 is pressed
downward. As shown in FIG. 5, when the outer cap or button 16 is
pressed downward (against the bias of the lower spring 21), the
outer cap end 34 in turn presses downward on the arms 51 of the
unifying piece 20, causing the unifying piece 20 to move downward.
As the unifying piece 20 moves downward, the arms 51 of the
unifying piece 20 move through the openings 23a in the upper
portion 23 of the housing. The arms 51 are thus inserted into the
cardboard cylinder in the center of the roll of towels 2 or onto
the end of the towel roll itself, creating a friction with the
towel roll 2 or inside of the cardboard cylinder of the towel roll
2 and preventing the roll 2 from rotating around the tube 3 of the
roll holder and dispenser 1. When the outer cap or button 16 is
released, the lower spring 21 returns the outer cap 16 and the
unifying piece 20 to their original positions.
[0064] As the unifying piece 20 is moved downward the lower spring
21 is compressed by the force of the lower rim or seat 50 of the
unifying piece 20 on the upper end 52 of the lower spring 21, as
shown in FIG. 5. In this position the lower spring 21 biases the
unifying piece 20 upward. Thus, when the pressing force on the
outer cap 16 is released, the outer cap 16 is forced back upward
into the default position shown in FIG. 4.
[0065] As shown in FIG. 5, as the outer cap 16 is pressed, the
inner cap 17 and the plunger 18 are also moved downward via the
force of the outer cap edge 33 (which surrounds the hole 31 of the
outer cap 16) against the catches 39 of the prongs 38 of the inner
cap 17. This force, however, does not cause the upper spring 19 to
be compressed or the curved channels 43 to move relative to the bar
32 of the outer cap 16, because the lower end 48 of the upper
spring 19 is seated on the upper rim or seat 49 of the unifying
piece 20, and the unifying piece 20 is also being moved downward
the same distance as the inner cap 17. As a consequence, the
plunger 18 does not rotate, the bar 32 remains fully received at
the bottom of the channels 43, and the upper spring 19 is not
compressed.
Base of Roll Holder
[0066] As shown in FIGS. 1 and 2, the base 5 of the roll holder 1
has a top 55, at least one side 56, and a bottom 57 forming an
opening 58. An elongated slot 59 is formed in the side 56 of the
base 5.
[0067] The base 5 shown in the drawings contains a suction device
that permits it to be secured to a work surface. However, the base
5 may be replaced by a mount so that the roll holder 1 may be
secured to a wall, cupboard, or other structural support. In this
case, the tube 3 can be configured so that it extends at a ninety
degree angle from the wall or other support, or the tube 3 may be
configured to be "L-shaped" so that the roll-receiving tube 3 of
the roll holder 1 is parallel to the wall or cupboard. In this
configuration, the handle assembly 6 may be made in the same way as
described above and be installed and operated in the end of the
tube 3 in precisely the same manner as described above, the only
exception being that the unit would be mounted to the wall,
cupboard, or other surface by screws, nails, adhesive mounts, or
other well-known mounting methods and not be secured by a suction
assembly such as suction assembly 7 described in detail below.
[0068] The base 5 may also be secured to the wall, cupboard, or
other structural support by the suction device 7 described below.
In addition, the base 5 may be set on a counter or work surface
without use of the suction device 7 or, alternatively, may be made
without the suction device and simple set on the counter or other
work surface for use.
Suction Assembly
[0069] As shown in FIG. 2, the suction assembly 7 is housed inside
the base 5.
[0070] The suction assembly 7 comprises a suction pad 60, a suction
pad plate 61, a handle 62, and a pivot 63. The suction plate 61 has
a top side 64. Two spaced-apart bridge-like structures 65 extend
away and upward from the top side 64 of the plate 61. Each
bridge-like structure 65 has an underside 66 that is ramped or
sloped. The pivot 63 is situated between the bridge-like structures
65.
[0071] The suction pad 60 is larger in diameter than the suction
pad plate 61. The suction pad has a central portion 68 and an outer
portion 69. When the suction pad 60 is placed on the top side 64 of
the suction pad plate 61, the outer portion 69 of the suction pad
60 extends beyond and outward from the suction pad plate 61. The
central portion 68 of the suction pad 60 is situated on and
connected to the top side 64 of the plate 61.
[0072] The handle 62 extends from the sloped underside 66 of one of
the bridge-like structures 65, through a hole 70 in the pivot 63,
along the sloped underside 66 of the other bridge-like structure
65, and outward thorough the elongated slot 59 in the side 56 of
the base 5 above the bottom opening 58 of the base 5. The handle
62, so situated, is in sliding contact with the sloped undersides
66 of the bridge-like structures 65.
[0073] The suction assembly 7 is oriented so that the outer portion
69 of the suction pad 60, which extends outward from the plate 61,
makes contact with the counter or work surface through the bottom
opening 58 of the base 5.
[0074] Suction device 7 is operated by moving its handle 62 from
one side of its elongated slot 59 to the other.
[0075] Movement of the handle 62 in one direction causes the handle
62 to slide along the upward slopes of the underside 65 of the
bridge-like structures 65. As the handle 62 slides along the slope
underside 65, it pulls the plate 61 from which the bridge-like
structures 65 extend, in turn causing the plate 61 to pull the
central portion 68 of the suction pad 60 away from the counter,
while the outer portion 69 of the suction pad 60 remains in contact
with the counter. As the central portion 68 of the suction pad 60
is pulled away from the surface, the air pressure between the
central portion 68 of the suction pad 60 and the counter decreases,
creating a partial vacuum under the central portion 68 of the
suction pad 60, which, in turn causes the outer portion 69 of the
suction pad 60, which is still in contact with the counter, to
adhere to the counter.
[0076] Movement of the handle 62 in the opposite direction in the
slot 59 relaxes the central portion 68 of the suction pad 60,
causes the central portion of the suction pad 60 to move toward the
counter, increases the pressure under the central portion 68 of the
suction pad 60, dispels the partial vacuum, and allows the suction
pad 60 to be easily removed from the surface to which it is was
formerly mated.
Operation of the Suction Device
[0077] The roll holder 1 is placed in a desirable location on a
work surface or counter. In this position, the outer portion 69 of
the suction pad 60 is in contact with the countertop. The handle 62
of the suction device 7 is moved in the elongated slot 59. As the
handle 62 moves in the slot 59 the central portion 68 of the
suction pad 60 is raised upward, creating a partial vacuum under
the central portion 68 of the suction pad 60 while the outer
portion of the 69 of the suction pad 60 remains on the countertop.
The vacuum or suction so created under the central portion 68 of
the suction pad causes the roll holder 1 to stick or adhere to the
counter in the desired location.
[0078] So adhered, the roll holder and towel dispenser 1 will not
be moved or tipped on the counter or work surface by the unrolling
or tearing of the individual towels from the roll 2, because the
roll holder and dispenser 1 is firmly secured to the counter by the
suction device 7.
[0079] If it is desired to move the roll holder and dispenser 1 to
a different location, the handle 62 of the suction device 7 is
moved in the opposite direction in the slot 59 in the side 56 of
the base 5 to relieve the partial vacuum under the central portion
68 of the suction pad 60. The roll holder 1 may then be moved to a
different location on the countertop, where it may again be adhered
by suction in the manner stated above. The roll holder 1 may, of
course, be moved by grasping the handle 6, or, if there are no
towels 2 on the holder 1, by grasping the tube 3.
[0080] It is understood that while certain forms of this invention
have been illustrated and described, it is not limited thereto
except insofar as such limitations are included in the following
claims and allowable functional equivalents thereof.
