Coin roll
Abstract
An apparatus for verifying that a correct number of coins of a
particular denomination are disposed in a paper, plastic, or other
type of roll includes an inside line or other demarcation along an
inner circumference of the roll that includes a thickness that is
preferably greater than that of one coin. If, when filling, the
line or demarcation is fully visible then too few coins are in the
roll. If, when filling, none of the line or demarcation is visible,
then too many coins are in the roll. If, when filling, only a
desired portion of the line or demarcation is visible, then a
correct number of the coins are in the roll. Various shapes and
sizes for the inside line and demarcation are disclosed. An
optional outer line is also disclosed that is concentric to the
inside line.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention, in general, relates to coin holders
and, more particularly, to tubes or rolls that are used to contain
a predetermined number of a particular coinage.
[0003] Coin rolls or coin tubes, the terms being used
interchangeably herein, are used to store a predetermined number of
coins of the same denomination. For example, fifty pennies are
stored in a "penny" roll, forty nickels are stored in a "nickel"
roll, fifty dimes are stored in a "dime" roll, and forty quarters
are stored in a quarter roll.
[0004] When a person tries to redeem several rolls of quarters,
each valued at ten dollars, many merchants balk at accepting the
rolls because they are uncertain if the rolls are properly filled.
They may be losing fifty cents per roll and not know.
[0005] Similarly, when coins are being counted and rolls are being
filled there is also uncertainty whether or not the correct number
of coins has been deposited in each roll. Are there 38, 39, 40, 41,
or 42 quarters in the quarter roll?
[0006] Unfortunately, the actual number of coins that are stored in
a roll can vary and it is not easy to tell by any outward visual
inspection as to how many coins are actually in each roll.
[0007] There are two basic types of rolls that are available. Some
have both ends open. Others are rolled at one end to prevent coins
(of the proper denomination) from passing beyond the rolled
portion. Additionally the rolled-end provides a starting reference
point and is open at an opposite remaining end. Accordingly,
outside demarcations may be of help with rolled coin tubes (rolls)
but are of little use with those that are open at both ends.
[0008] Additionally, if a line were to be used the user is never
quite sure whether the coins should just reach to the line's edge
or cover the line so it is no longer visible.
[0009] Also, a demarcation line disposed on an outside of a coin
tube is of little help because of the variability in folding the
outside over the coins that is possible.
[0010] Accordingly, there exists today a need for a coin roll that
helps ameliorate the above-mentioned difficulties.
[0011] Clearly, such an apparatus would be a useful and desirable
device.
[0012] 2. Description of Prior Art
[0013] Coin rolls are, in general, known. The following three
patents describe related devices.
[0014] U.S. Pat. No. 4,089,459 to Huard that issued on May 16,
1978;
[0015] U.S. Pat. No. 2,168,504 to Youmans that issued on Aug. 8,
1939; and
[0016] U.S. Pat. No. 610,959 to Cable that issued on Sep. 20,
1898;
[0017] While the structural arrangements of the above described
devices may, at first appearance, have similarities with the
present invention, they differ in material respects. These
differences, which will be described in more detail hereinafter,
are essential for the effective use of the invention and which
admit of the advantages that are not available with the prior
devices.
OBJECTS AND SUMMARY OF THE INVENTION
[0018] It is an object of the present invention to provide a coin
roll that provides an accurate visual indication of the number of
coins in a coin roll.
[0019] It is also an important object of the invention to provide a
coin roll that provides an accurate visual indication if there are
too few coins in a coin roll.
[0020] Another object of the invention is to provide a coin roll
that provides an accurate visual indication if there are too many
coins in a coin roll.
[0021] Still another object of the invention is to provide a coin
roll that provides an accurate visual indication of the number of
coins and is disposed on an inside of a coin roll.
[0022] Still yet another object of the invention is to provide a
coin roll that is easy to manufacture.
[0023] Yet another important object of the invention is to provide
a coin roll that includes a demarcation on an inside of a coin
roll.
[0024] Still yet another important object of the invention is to
provide a coin roll that provides both an inner and an outer
marking on a coin roll
[0025] A first continuing object of the invention is to provide a
coin roll that includes a visual indication that at a glance
reveals whether there are too few coins in the roll, too many coins
in the roll, or the correct number of coins in the roll.
[0026] A second continuing object of the invention is to provide a
coin roll that includes a thick line or other demarcation disposed
on an inside of a coin roll, wherein if a thick inside line is
visible then too few coins are in the roll, and if no line is
visible then too many coins are in the roll, and if a thin line is
visible then the correct number of coins are in the roll.
[0027] A third continuing object of the invention is to provide a
coin roll that includes a thick line or other demarcation disposed
on an inside of a coin roll, wherein if a thick inside line or
demarcation is visible then too few coins are in the roll, and if
no line or demarcation is visible then too many coins are in the
roll, and if a thin line or demarcation is visible then the correct
number of coins are in the roll and which also includes a thick
line or other demarcation disposed on an outside of a coin roll
that is concentrically aligned with the inside thick line or inside
demarcation, and wherein when viewed from a longitudinal side of
the coin roll and not from an end thereof, if a thick outside line
or demarcation is visible then too many coins are in the roll, and
if no outside line or demarcation is visible then too few coins are
in the roll, and if a thin outside line or demarcation is visible
then the correct number of coins are in the roll.
[0028] A fourth continuing object of the invention is to provide a
coin roll that eliminates the need for a coin counting machine to
determine a proper quantity of coins in the coin roll.
[0029] A fifth continuing object of the invention is to provide a
coin roll that provides an increase in both speed and ease in
determining that a proper number of coins are disposed in the coin
roll.
[0030] A sixth continuing object of the invention is to provide a
coin roll that eliminates the need for a coin stacking type of tube
to determine a proper quantity of coins prior to placing the coins
in the coin roll.
[0031] A seventh continuing object of the invention is to provide a
coin roll that eliminates the need for a painstaking counting of
the number of coins that are being placed in the coin roll.
[0032] An eight continuing object of the invention is to provide a
coin roll that includes printing on the inside of the coin
roll.
[0033] Briefly, a coin roll or tube that is constructed in
accordance with the principles of the present invention has an
inside line extending along at least a portion of an inside
circumference of the roll and disposed a predetermined distance
away from a reference point, the reference point being disposed at
an opposite longitudinal end of the roll. The inside line includes
a thickness that is at least equal to or which exceeds the
thickness of one of the coin denominations that the roll is
intended to hold. If too few coins are in the roll, the entire
thickness of the inside line is visible on the inside of the roll.
If one too many coins are in the roll, the inside line is no longer
visible. If the correct number of coins are included in the roll,
the inside line appears thinner and preferably no longer exceeds
the thickness of one of the coins. An optional outer line,
identical to the inside line, is optionally included disposed on an
exterior of the roll and concentric with respect to the inside
line. The inside line may include any preferred demarcation, for
example a diamond, circle, or square or any other preferred
geometric or other shape, or a plurality thereof, that includes a
similar radial location and dimension.

DETAILED DESCRIPTION OF THE INVENTION
[0039] Referring on occasion to drawing FIG. 2 and FIG. 3 and now
in particular to FIG. 1 is shown, a coin roll, identified in
general by the reference numeral 10.
[0040] The coin roll 10, also known as a coin tube or simply as a
"roll" or a "tube" is intended to hold a predetermined quantity of
any desired denomination of a coin 12.
[0041] A bottom 10a of the roll 10 may include a rolled edge 14 or
a lower exterior demarcation line 16, both of which provide a
reference point from which a plurality of the coins 12 are added
one atop the other inside of the roll 10.
[0042] The coin 12 that is visible in the drawings FIGS. 1-3 is
always a top coin 12 and it is disposed over a plurality of the
coins 12 that are stacked on atop the other and which begin at the
reference point 14, 16.
[0043] An inside line 18 is a type of demarcation that extends
along at least a portion of an inside circumference of the roll 10
and is disposed a predetermined distance away from the reference
point, either away from the rolled edge 14 or away from the lower
exterior demarcation line 16. Typically, the insider line 18 will
be disposed nearer to an end of the roll 10 that is on an opposite
end as that compared to the reference point 14, 16 and typically,
it will extend radially around an inside circumference of the roll
10.
[0044] The inside line 18 preferably extends all the way around the
inside circumference and it includes a thickness that is at least
equal to or which exceeds the thickness of one of the coins 12 that
the roll 10 is intended to hold. Obviously then, the inside line 18
would be thinner if the roll 10 were intended to hold dimes than if
the roll 10 were intended to hold quarters.
[0045] The term "thickness" as used herein and as is applied to the
inside line 18 including any version or demarcation thereof
appertains to a dimension that is parallel with a longitudinal axis
of the roll 10.
[0046] Outer dashed lines show the location inside of the roll 10
of the inside line 18 and where the top coin 12 is disposed with
respect to the inside line 18. The outer dashed lines are not
imprinted on the roll 10. They are shown in the drawing figure to
help provide an understanding of the position of the uppermost coin
12 with respect to the inside line 18 and to that purpose they
yield another view (i.e., looking through a sidewall of the roll
10).
[0047] A small outer segment of an optional outside line 20 is
included in each of the FIGS. 1-3. The outside line 20 is described
in greater detail hereinafter.
[0048] If too few of the coins 12 are present in the roll 10, the
entire thickness of the inside line 18 is visible above the
top-most coin 12 on the inside of the roll 10. FIG. 1 shows that
the entire thickness of the inside line 18 is visible and that one
additional coin 12 is needed.
[0049] If an upper edge of the top most coin 12 is located just
below the inside line 18, this indicates that one too few coins 12
are present in the roll 10 and that one additional coin 12 should
be added.
[0050] Accordingly, the inside line 18 is able to provide a first
discernible indication indicative of when too few of the coins 12
are disposed in the roll 10.
[0051] If the upper edge of the top most coin 12 is located well
below the inside line 18, this indicates that two or more
additional coins 12 need to be added.
[0052] Referring now to FIG. 2, if a proper quantity (number) of
the coins 12 are present in the roll 10, only a thin portion of the
inside line 18 is visible when viewed from the inside of the roll
10.
[0053] The thin portion of the inside line 18 that is visible from
the inside of the roll 10 when the proper number of the coins 12
are disposed in the roll 10, preferably is thinner than the
thickness of any one of the coins 12. This is to prevent any
tendency to add yet another coin 12 (one too many) to the roll 10
and still be able to see any portion of the inside line 18 when an
excess of the coins 12 are disposed in the roll 10. Therefore, the
maximum thickness of the inside line 18 should not generally be
allowed to exceed the combined thickness of two of the coins 12. An
exception to this is shown in FIG. 5 and is described in greater
detail hereinafter.
[0054] Accordingly, the same inside line 18 that provided the first
discernible indication when too few of the coins 12 were disposed
in the roll 10 is now able to provide a second discernible
indication that is different in appearance than the first
discernible indication when the correct number of the coins 12 are
disposed in the roll 10.
[0055] Therefore, the thin portion of the line 18 that is visible
above the upper surface (edge) of the upper-most coin 12 when the
inside of the roll 10 is viewed indicates, with certainty, that the
correct number of the coins 12 are disposed in the roll 10.
[0056] Referring now to FIG. 3, if at least one too many of the
coins 12 are present in the roll 10, the inside line is no longer
visible when viewed from the inside of the roll 10. This indicates
that too many of the coins 12 are present in the roll 10 and that
one (or more) of the coins 12 needs to be removed from the roll 10
until the thin portion of the inside line 18 is visible on the
inside of the roll 10.
[0057] Accordingly, the same inside line that provided the first
discernible indication when too few of the coins 12 were disposed
in the roll 10 and the second discernible indication when the
correct number of the coins 12 were disposed in the roll 10 is now
able to provide a third discernible indication that is different in
appearance than the first discernible indication and also different
in appearance than the second discernible indication when too many
of the coins 12 are disposed in the roll 10.
[0058] Referring momentarily to FIG. 4, the use of spaced-apart
diamonds 22, circles 24, and squares 26 illustrate how other
geometric-shaped demarcations can be used on the inside of a
modified roll 28 to obtain the same benefits providing that the
height (extending along a longitudinal length of the modified roll
28) is nearly the same as that of the inside line 18. Obviously,
any preferred shape or combination of shapes can be used as the
preferred demarcation for the inside line 18.
[0059] The geometric-shaped demarcations 22, 24, 26 can be used to
quickly determine if the proper number of coins are in the modified
roll 28. If the entire geometric shape is visible, then too few
coins are present. If none of the geometric shape is visible, then
too many coins are present. If a portion of the geometric shape is
visible, then the proper number of coins are present.
[0060] The geometric-shaped demarcations 22, 24, 26 can, for some
users, be a faster determinant at verifying that a proper number of
coins are present than determining the thickness of the inside line
18 because, rather than having to judge line thickness, a mere
glance at the shape of the demarcations is used to determine the
number of coins. Any other preferred type of geometric shape or
pattern can be used for the demarcations 22, 24, 26 to replace the
inside line 18.
[0061] Referring again to FIGS. 1-3, the outside line 20 is
optionally included with the roll 10 (or the modified roll 28) and
is concentric with respect to the inside line 18. The outside line
20 is useful in verifying that a correct number of coins 12 are in
the roll 10.
[0062] Normally, an open upper end 10b of the roll 10 is folded
over the upper surface of the top-most coin 12 when the roll 10 is
filled to capacity. The recipient of the filled roll 10 needs
assurance as does the person who filled it to confirm that the
correct number of the coins 12 are included in the roll 10. Such
assurance is provided to the person who filled the roll 10 by the
inside line 18, as was described in detail hereinabove.
[0063] After the upper end 10b has been closed, the recipient
cannot observe the inside line 18 and would have no way to
determine whether the proper number of coins 12 are in the roll
10.
[0064] The outside line 20 may similarly extend fully around the
outer circumference of the roll 10, 28 or only partially, as shown
by the segment of the outside line 20. If preferred, the alternate
diamond 22, circle 24, square 26 or other demarcation shapes can be
used to form the outside line 20 or segment thereof.
[0065] Accordingly, the inside line 18 or inside geometric-shaped
demarcations 22, 24, 26 are useful to whomever is filling the roll
10 in verifying that a correct number of coins 12 are included. The
outside line 20 is of primary use to those who receive the filled
roll 10 in alleviating their concern as to whether or not a proper
number of coins 12 are in the roll 10.
[0066] Referring now in particular to FIG. 1, when too few of the
coins are in the roll 10 and the upper end 10b is folded, none of
the outside line 20 is visible along the outer circumference
(outside diameter) of the roll 10.
[0067] Referring now in particular to FIG. 2, when the proper
number of the coins are in the roll 10 and the upper end 10b is
folded, a portion of the outside line 20 that is thinner than the
thickness of one of the coins 12 is visible along the outer
circumference (outside diameter) of the roll 10.
[0068] Referring now in particular to FIG. 3, when too many of the
coins are in the roll 10 and the upper end 10b is folded, all of
the outside line 20 is visible along the outer circumference
(outside diameter) of the roll 10.
[0069] Accordingly, both the person who fills the roll 10, 28 and
the person who receives it after it has been filled are assured
that the correct number of coins 12 are disposed in the roll
10.
[0070] This promotes ease and speed of filling of the roll 10 and
general acceptance of the filled rolls 10 by retailers, banks,
other establishments, etc. If the rolled edge 14 is not used, after
a few of the coins 12 are placed in the roll 10, they are adjusted
along the longitudinal length of the roll so that the exterior
demarcation line 16 aligns with the bottom edge of the bottom-most
coin 12 prior to a complete filling of the roll 10. The exterior
demarcation line 16 can of course be modified as desired to include
a dashed line, a series of perforations, a crease or any other
desired indication as to where the bottom of the roll 10 is
located.
[0071] Other changes are possible to those having benefited from
the instant disclosure. For example, it is easy to learn how to use
the coin roll 10, the learning curve taking only a minute or so.
Instructions for the proper use of the roll 10 can be placed on the
outside of the roll 10, if desired. While paper is a preferred
material for the coin roll 10, plastic is also possible. The
plastic may be either opaque or translucent, as desired.
[0072] If preferred, the inside line 18 can also include
perforations or indentations of a comparable thickness as that of
the inside line 18 which can be used to provide a similar
demarcation-indication as to the quantity of coins in the roll 10.
However, they ideally need to be of the same thickness as the
inside line 18 to provide the same benefit. This could be useful
for visually impaired users and possibly for others.
[0073] Referring now to FIG. 5 is shown a second modified roll 30.
A series of figure-eight shaped demarcations 32 are printed on the
interior of the second modified roll 30 in a manner similar to the
inside line 18 and the inside geometric-shaped demarcations 22, 24,
26. The figure-eight shaped demarcations 32 extend radially around
an inside circumference of the second modified roll 30, each of the
figure-eight shaped demarcations 32 being equidistant from the
rolled edge 14.
[0074] When the proper number of coins 12 are in the second
modified roll 30, a lower half 34 of the figure-eight shaped
demarcations 32 is covered from view when viewed from the inside of
the second modified roll 30 while an upper half 36 of the
figure-eight shaped demarcations 32 remains fully in view. When a
proper number of the coins 12 are disposed in the second modified
roll 30 the top surface of the uppermost coin 12 is disposed in the
middle of the figure-eight shaped demarcations 32.
[0075] A mere glance inside the second modified roll 30, when
properly filled, reveals essentially only the upper half 36, or top
circle, of each of the figure-eight shaped demarcations 32, thereby
providing a new pattern recognition that is different than that
which is visible when either too many or too few of the coins 12
are included. Pattern recognition provides a method of recognition
that for certain users is easier and faster than assessing the
thickness of the inside line 18.
[0076] If all or a portion of the lower half 34 of each of the
figure-eight shaped demarcations 32 is visible, then too few coins
32 are in the second modified roll 30.
[0077] If all or a portion of the upper half 36 of each of the
figure-eight shaped demarcations 32 is obscured from view, then too
many coins 12 are in the second modified roll 30.
[0078] Of course the overall thickness, extending along a
longitudinal length of the second modified roll 32, can be greater
than the combined thickness of two of the coins 12. It can be equal
to the combined thickness of three or more of the coins 12. This is
possible because the determination as to the correct number of
coins 12 being in the second modified roll 30 depends upon the
final shape of the figure-eight shaped demarcations 32 that remain
visible after filling when viewed from the inside of the second
modified roll 30.
[0079] It is therefore possible to further modify the second
modified roll 32 (or any version of the invention herein) by
including (printing) shapes on the inside that are different than
that of the figure-eight shaped demarcations 32 and which are
thicker, longitudinally, than the combined thickness of two of the
coins 12. Similarly, it is also possible to rely on pattern
recognition, as taught herein to verify that a proper number of the
coins 12 are disposed in the second modified roll 30 (or any other
version) when the longitudinal length of the demarcation used is
less than the combined thickness of two of the coins 12.
[0080] The invention has been shown, described, and illustrated in
substantial detail with reference to the presently preferred
embodiment. It will be understood by those skilled in this art that
other and further changes and modifications may be made without
departing from the spirit and scope of the invention which is
defined by the claims appended hereto.
