Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to and the benefit of U.S.
Provisional Patent Application No. 63/068,165, filed Aug. 20, 2020
and titled "Compressed Hollow Coreless Re-Formable Roll Products;"
the contents of which (including Appendices attached therewith) as
are hereby incorporated by reference in their entireties.
BACKGROUND
Technical Field
[0002] The present disclosure relates to rolled absorbent products
and, in certain embodiments, to compressed and hollow coreless
rolls of absorbent paper products such as tissue and toweling,
commonly referred to as tissue products including toilet paper and
towel products including paper towels.
Related Art
[0003] Certain rolled goods, including absorbent paper products,
are inherently bulky, which can adversely impact cost and/or
logistics when transporting these products in large volumes. It is
known to compress rolled goods, including absorbent paper products,
to reduce volume and/or increase density thereof for transportation
and storage. When ready for use, the compressed rolled goods may be
subjected to one or more forces to be re-formed or otherwise
returned to (or nearly to) an original uncompressed state. Certain
rolled goods, prior to and once compressed, include central
cavities sized to receive a spindle or comparable component for
roll-feed dispensing of the rolled goods once re-formed or
uncompressed. While central cavities may contain a paperboard (or
the like) core, it is also known to provided compressed rolled
goods with a coreless central cavity. This, among other advantages,
reduces waste product associated with the rolled good.
[0004] Conventional rolled products have sought to remedy the
above-mentioned bulkiness and waste associated with their packaging
and use by removing the paperboard core and/or compressing the
rolled product. Despite these and other observed advantages,
inefficiencies can also arise with certain compressed and coreless
rolled products. For example, location of the central core (whether
via use of a spindle or otherwise) can be time-consuming and/or
inaccurate. Oftentimes, telescoping of an inner portion of the
rolled product may occur, resulting in the inner portion being
pushed outwardly due to unintended contact of the product with the
spindle. Still further, an inner portion of the rolled product may
bind or experience "locking up" around the spindle as the roll is
used, rendering an inner portion of the rolled product unusable
waste. Both phenomena negatively impact the ability of compressed
coreless rolled products to deliver expected consumer performance,
expected manufacturer performance, and expected environmental
waste-avoidance. Thus, a need exists for compressed coreless rolled
products that minimize and/or substantially avoid these
phenomena.
BRIEF SUMMARY
[0005] To address the telescoping and locking-up phenomena, along
with other technical considerations, there is described herein
according to various embodiments a compressed coreless rolled
product comprising: an inner surface defining a central cavity
having an inner diameter; and an outer surface having an outer
diameter larger than the inner diameter, wherein: the outer
diameter is at least five inches; and a ratio of the inner diameter
to the outer diameter is at least 0.35.
[0006] In certain embodiments, the inner diameter may be any of: at
least 1.75 inches; from 1.75 to 4.0 inches; at least 2.0 inches;
between 2.0 and 3.0 inches; or 2.5 inches. In certain embodiments,
the inner diameter may be 2.0 inches and the outer diameter may be
5.0 inches. In these and other embodiments, the outer diameter may
be 5.6 inches, with a ratio of 0.36. As another example, the outer
diameter may be 7.0 inches and the ratio may be 0.40. In one
embodiment, the outer diameter is between 7.0 and 12.0 inches.
[0007] There is also described herein according to various
embodiments a compressed coreless rolled product comprising: an
inner surface defining a central cavity having an inner diameter;
and an outer surface having an outer diameter larger than the inner
diameter, wherein: a difference between the outer diameter and the
inner diameter defining a thickness of at least 2.9 inches; and a
ratio of the inner diameter to the outer diameter is at least
0.35.
[0008] In certain embodiments, the thickness may be any of: at
least 4.0 inches; between 3.0 and 12.0 inches; exactly 5.0 inches;
or exactly 3.25 inches. In these and other embodiments, the ratio
may be at least 0.40.
[0009] According to various embodiments there is also described a
method of producing a compressed coreless rolled product, the
method comprising the steps of: winding an absorbent sheet around a
forming core member until a rolled product having an outer diameter
of at least five inches is formed; removing the forming core member
from the rolled product to form a coreless rolled product having a
hollow central cavity with an inner diameter, a ratio of the inner
diameter to the outer diameter being at least 0.35; and compressing
the coreless rolled product such that the hollow central cavity is
substantially collapsed.
[0010] In certain embodiments of the method, the forming core
member is a tubular paperboard core, which may be re-usable. In
these and other embodiments, wherein a difference between the outer
diameter and the inner diameter defines a thickness, the thickness
may be between 3.0 and 12.0 inches.
[0011] According to various embodiments there is also described a
method of delivering a compressed coreless rolled product, the
method comprising the steps of providing the compressed coreless
rolled product described herein; re-forming the compressed roll by
expanding the substantially collapsed central cavity; and mounting
the re-formed compressed roll about a spindle.
[0012] In certain embodiments of this method a ratio between a
diameter of the spindle and the inner diameter of the compressed
coreless rolled product is between one and three. In these and
other embodiments, the ratio may be between two and three. In still
other embodiments, a ratio between a diameter of the spindle and
the inner diameter of the compressed coreless rolled product may be
at least one or at least two.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
[0023] The invention is described in detail below in connection
with the various figures and for purposes of illustration. The
invention is also defined in the appended claims. It should be
understood, though, that only some, but not all embodiments are
shown and described herein. Indeed, the embodiments may take many
different forms, and accordingly this disclosure should not be
construed as limited to the embodiments set forth herein. Rather,
these embodiments are provided so that this disclosure will satisfy
applicable legal requirements. Still further, terminology used
throughout herein is given its ordinary meaning, except as
supplemented immediately below, and like numbers refer to like
elements throughout.
[0024] "Tissue" rolls or similar terminology refers to cellulosic
fiber tissue products, while "bath tissue" rolls must be flushable
and are typically manufactured without a substantial amount of
permanent wet strength resin; as opposed to paper toweling, or
kitchen roll towel, which has a substantial amount of wet strength
resin. Accordingly, the invention described herein may be employed
with respect to absorbent papers in which the sheets are not
spoiled or defaced, including with bath tissue, kitchen roll towel,
other paper toweling formats, or even napkin stock.
[0025] Referring first to FIGS. 1-3 in combination, the compressed
coreless rolled product 10 according to various embodiments is
illustrated in multiple states, namely an original uncompressed
state (see FIG. 1), a compressed state (see FIG. 2A), and a
re-formed state (see FIG. 2B). The compressed coreless rolled
product 10 may be initially formed by winding the sheet of the
compressed coreless rolled product 10 around a forming core member
(e.g., a paperboard core) having a diameter ranging from 25 mm to
50 mm. After rolling, the forming core member is removed, providing
a hollow coreless roll of the rolled product having a coreless
central cavity 12 (see FIG. 2A). The compressed coreless rolled
product 10 may then be compressed, into a state as illustrated in
FIG. 2A.
[0026] As evident from FIG. 2A, the compressed coreless rolled
product 10 maintains a flattened shape having: a substantially
collapsed central cavity 12, a pair of longer sides 14 that may be
relatively flattened and may have a central portion approaching
being generally planar, a pair of shorter sides 16 that after
initial compression are more rounded and may approach being
generally semi-cylindrical. The compressed coreless rolled product
10 is thus characterized largely by a thickness that is measured
from the perpendicularly longer sides 14 through the central axis
20 of the substantially collapsed central cavity 12, which
corresponds to the central axis of the forming core member about
which the compressed coreless rolled product was initially
wound.
[0027] FIG. 2B illustrates the compressed coreless rolled product
10 in the re-formed state. Re-forming may occur by simple
application of hand pressure, as described elsewhere herein,
principally on the shorter sides 16 of the rolled product. As
evident, the compressed coreless rolled product 10 recovers a shape
near that of its original state (see FIG. 1), but for certain
irregularities expected adjacent the coreless central cavity 12. If
desired, the irregularly shaped cavity 12a (see FIG. 2B) may be
further re-shaped by hand prior to mounting thereof on a spindle
(or the like) for dispensing or on a re-usable dispensing core,
which may also be re-inserted prior to mounting the roll on the
spindle.
[0028] Although not a focus of the present disclosure, from FIG. 3
it may be understood that a package 50 may be formed containing
four (or any desired number of) compressed coreless rolled products
10. Due to the collapsed central cavities 12 and the compressed
state of the rolled product (as previously described herein), the
size and density of the package 50 may also be compressed. In this
example configuration, a volume savings of up to 42% may be
achieved as compared to conventional packaging for uncompressed
rolled products. Other packaging configurations (not shown) may
achieve even larger volume savings, as known. To ensure achievement
of maximum savings, a polymer film 52 or comparable wrapping
material may be placed around the compressed coreless rolled
products 10, thereby ensuring the packaging volume is consistent
and constant.
[0029] Turning now to FIGS. 4A-C, illustrated therein are various
structural and dimensional characteristics of the compressed
coreless rolled product 10 according to various embodiments.
Generally, the compressed coreless rolled product 10 has a coreless
central cavity 12 (as previously discussed), an interior facing
surface 22, and an exterior facing surface 24. Relative to the
coreless central cavity 12, the interior facing surface 22 defines
an inner diameter 32 (see FIG. 4B) and the exterior facing surface
24 defines an outer diameter 30 (see FIG. 4A) of the compressed
coreless rolled product 10.
[0030] Collectively a difference between the outer and inner
diameters 30, 32 define a thickness 34 of the compressed coreless
rolled product 10. In certain embodiments, the thickness may range
from approximately 2.5 inches to 8.0 inches. In at least one
embodiment, the thickness may be 2.9 inches. In another embodiment,
the thickness may be 7.8 inches. Combinations of these ranges may
also be selected for the thickness 34.
[0031] According to various embodiments, the inner diameter 32 may
range from approximately 0.5 inches to 6.0 inches. In at least one
embodiment, the inner diameter 32 may range from approximately 1.5
to 2.0 inches. In another embodiment, the inner diameter 32 may be
any of 1.625 inches, 1.75 inches, 1.83 inches, or 2.25 inches.
Combinations of these ranges may also be selected for the inner
diameter 32.
[0032] The outer diameter 30 may also vary across a range,
dependent in part upon how much volume of material (i.e., paper) is
desired for providing on rolled product. This volume may be
quantified and/or calculated also based upon the thickness 34 of
the product, representing a difference between the outer and inner
diameters 30, 32. According to various embodiments, the outer
diameter 30 may range from approximately 4.5 to 12.0 inches. In at
least one embodiment, the outer diameter may range from 5.0 to 9.0
inches. In another embodiment, the outer diameter 30 is one of at
least 5.0 inches, at least 6.0 inches, or at least 7.5 inches.
Combinations of these ranges may also be selected for the outer
diameter 30.
[0033] The difference between the outer and inner diameters 30, 32
is oftentimes expressed as a ratio (i.e., the inner diameter
divided by the outer diameter, referred to elsewhere herein as the
"I/O ratio"). According to various embodiments, the I/O ratio may
range from 0.03 to 0.95. In at least one embodiment, the I/O ratio
ranges from approximately 0.35 to 0.95. In another embodiment, the
I/O ratio is at least 0.35. Combinations of these ranges may also
be selected for the I/O ratio.
[0034] As a non-limiting example, consider a compressed coreless
rolled product 10 having an outer diameter 30 of 5.0 inches and an
inner diameter 32 of 1.75 inches. This exemplary product would have
an I/O ratio of exactly 0.35. As another example, a compressed
coreless rolled product 10 could have an outer diameter 30 of 6.0
inches and an inner diameter 32 of 2.0 inches, also resulting in an
I/O ratio of 0.35. Yet another example with an I/O ratio of 0.45
could be achieved with a 5.0-inch outer diameter 30 and a 2.0-inch
inner diameter 32. Various combinations can thus be envisioned, all
within the scope of the present invention, noting that a minimal
inner diameter of 1.75 inches is required to achieve an I/O ratio
of 0.35 or higher with a 5.0-inch outer diameter. Still further, as
the inner and outer diameters approach one another (i.e., become
closer in values), the I/O ratio increases.
[0035] From a theoretical perspective, it is known that hoop stress
is imposed upon compressed coreless rolled products like that of
the present invention when re-forming of those products is
attempted. This may be understood with reference to FIG. 4C,
wherein an induced external stress 36 may be imposed upon the
previously compressed coreless rolled product 10. The induced
external stress 36, in turn, imposes a tangential hoop stress 38
(denoted also as .sigma. in FIG. 4C) upon the compressed coreless
rolled product 10. The direction of the imposed tangential hoop
stress 38 is denoted by the accompanying arrow in FIG. 4C, notably
substantially perpendicular or transverse to the direction of the
force applied by the induced external stress 36.
[0036] The equation reproduced below calculates the imposed
tangential hoop stress 38.
.sigma. r = r i 2 .times. P i r o 2 - r i 2 .times. ( 1 - r i 2 r o
2 ) ##EQU00001##
[0037] The tangential hoop stress 38 (denoted also as .sigma.)
based upon the outer diameter 30 dimension (denoted as 1/2 thereof
in terms of a radius r.sub.o), the inner diameter 32 dimension
(denoted as 1/2 thereof in terms of a radius r.sub.i), and the
induced external stress 36 (denoted as P).
[0038] Notably, induced tangential hoop stress 38 governs, at least
in part, how easily a compressed coreless rolled product 10 can be
reformed. Specifically, the tangential hoop stress 38 is heightened
as the difference between the inner diameter 32 and the outer
diameter 30 decreases. Stated another way, the tangential hoop
stress 38 is heightened as the I/O ratio increases. Thus, with an
I/O ratio of at least 0.35, as provided in certain embodiments, a
tangential hoop stress 38 is induced that is greater than that
induced is the I/O ratio were, for example, 0.15.
[0039] As a result of the heightened tangential hoop stress 38 with
a greater I/O ratio, re-forming of the compressed coreless rolled
product 10 requires less externally induced stress 36. Stated
otherwise, it is easier for consumers (or others) to re-form the
compressed coreless rolled product according to various
embodiments, as compared to conventional rolled products having a
lower I/O ratio. As a non-limiting example, if a compressed
coreless rolled product 10 according to the present invention
comprises an outer diameter of about 5.6 inches and an I/O ratio of
about 0.36, the tangential hoop stress induced increases by about
52%, as compared to conventional rolled products.
[0040] Notably, having an increased I/O ratio according to various
embodiments (whether greater than 0.35 or otherwise), requires a
certain degree of increase in the inner diameter 32 of the
compressed coreless rolled product. For example, as compared to
certain conventional rolled products having an inner diameter of
1.6 inches and an outer diameter of 4.75 inches, the I/O ratio is
less than 0.35. Similarly, it is not possible to achieve an I/O
ratio of greater than 0.35 with an outer diameter less than 5.0
inches without having an inner diameter that is larger than
conventional inner diameters. An additional advantage due to this
arises regarding telescoping.
[0041] Referencing now FIG. 5, illustrated therein is an occurrence
of telescoping in a compressed coreless rolled product 10. As
generally known and understood, telescoping is a defect in a rolled
product attributable, at least in part, to a poorly re-formed and
unclear central cavity 12, which can lead to obstruction of proper
loading of the rolled product onto a dispenser, such as a spindle
(see FIG. 6). As illustrated in FIG. 5, an inner portion 42 of the
rolled product is axially extended (i.e., telescoped) outwardly
relative to the winding of the material of the remainder (or outer)
portion 40 of the rolled product. Telescoping can result in unused
portions of the rolled product, typically with respect to the inner
portion 42 that exhibits the telescoping.
[0042] Another recognized advantage from various embodiments is
that, as the inner diameter increases (for purposes of increasing
the I/O ratio, as previously described herein) a difference between
the inner diameter and a diameter of an associated spindle, as may
be used to mount the compressed coreless rolled product 10 is also
potentially increased, dependent in part upon the diameter of the
spindle itself. FIG. 6, in this regard, illustrates an exemplary
spindle 100. As generally known, a spindle 100 may include opposing
end portions 104 (i.e., stoppers to retain the rolled product once
mounted) and an intermediate rod 102 that is spindle-like or
elongated in shape and extending between the opposing end portions.
Certain spindles, as illustrated, may provide a nesting
configuration for the rod 102, with separate outer 102a and inner
102b portions being provided, each having slighting differing
(outer>inner) diameters 104a, 104b. Various spindle rod 102
diameters are well-known and understood, with the limitation that
they are dimensionally less than the inner diameter dimensions of
central cavities of associated rolled products.
[0043] As mentioned, though, as the inner diameter increases (to
increase the I/O ratio), a ratio of spindle to inner (or central
cavity) diameter increases. As this spindle/cavity ratio increases
from 1 to 3, occurrences of telescoping are reduced. This is
evident not only from chart 200 of FIG. 7, but also from the data
presented in Table 1, immediately below.
TABLE-US-00001 TABLE 1 Percent Differences Between Central Cavity
Diameters Telescoping Ratio 1.625'' 2.0'' % Difference 1-1.25
20.83% 12.50% 66.67% 1.25-1.5 20.00% 14.29% 40.00% 1.5-1.75 12.50%
11.11% 12.50% 2-3 0.00% 0.00% 0.00% 3 & up 0.00% 0.00%
0.00%
[0044] As illustrated above, it is also evident that a compressed
coreless rolled product 10 according to various embodiments, having
an inner diameter of 2.0 inches exhibits less telescoping (or a
lowered risk thereof), as compared to conventional rolled products
having an inner diameter of 1.625 inches. Above and beyond a
spindle/central cavity ratio of 2-3, telescoping is virtually
eliminated. And although this is true regardless of the inner
diameter of the rolled product, occurrences are significantly lower
with a larger inner diameter product (i.e., one also having a
heightened I/O ratio, as previously described). For example, a 23%
inner diameter increase to 2.0 inches reduces telescoping issues up
to 67%, as compared to a conventional 1.625-inch cavity
diameter.
[0045] Referencing now FIG. 8, illustrated therein is a chart 300
mapping a relationship between spindle/central cavity ratio and the
"locking-up" phenomena. While locking up occurrences start higher
for the 2.0 inch inner diameter compressed coreless rolled products
10, it is consistently lower from a ratio of 1 and upward,
revealing additional advantages with coupling of high
spindle/central cavity and I/O ratios, at least with respect to
re-forming, telescoping, and locking up. Further data regarding
locking-up advantages observed are provided in Table 2, below. For
example, it may be seen that a 23% inner diameter increase to 2.0
inches reduces telescoping issues up to 150%, as compared to a
conventional 1.625-inch cavity diameter.
TABLE-US-00002 TABLE 2 Percent Differences Between Central Cavity
Diameters Locking up Ratio 1.625'' 2.0'' % Difference up to 1
63.64% 100.00% -36.36% 1-1.5 47.73% 27.78% 71.82% 1.5-2 56.25%

150.00%
[0046] Further data regarding reductions in telescoping and
locking-up observed in various studies conducted is shown in Tables
3-6, provided below. The methodology employed in these studies,
conducted to demonstrate certain non-limiting advantages achieved
by one or more (or a combination of) increased I/O ratio, increased
spindle to inner diameter (or central cavity diameter) ratio, and
increased outer diameter, involved testing a hypothesis that
properly finding the center of the compressed coreless rolled
product is influential to alleviating telescoping and locking-up
issues. For example, participants who indicated telescoping and
locking-up issues were provided an additional compressed coreless
rolled product to test. Those participants then exhibited a 45%
decrease in telescoping and a 61% decrease in locking-up once the
center of the compressed coreless rolled product 10 was properly
located. Further, it was shown that an increased inner diameter
improved participants' ability to reform and install the compressed
coreless rolled product 10. It should be appreciated, though, that
the studies conducted, including their results, are non-limiting
examples and supportive of the further detailed disclosure provided
elsewhere herein.
[0047] As can be seen in Tables 3-4 below, a first study involving
a compressed coreless rolled product 10 having a 1.6'' inner
diameter and a second studying involving a compressed coreless
rolled product having a 2.0'' inner diameter was conducted. As
observed, the increased inner core diameter engendered an increased
consumer acceptance of the format. Stated another way, participants
in the two studies felt they gained more benefits (i.e., reduced
telescoping and locking-up) while using the 2.0'' inner diameter
compressed coreless rolled product, and were willing to change
their own behavior (e.g., more carefully find the center of the
compressed coreless rolled product) to enjoy those benefits.

[0048] Observed in Table 5 below is data related to participants
included in both the first study and the second study. As shown,
60% of participants successfully resolved their issues when given a
second compressed coreless rolled product to try. Those
participants who continued to experience difficulty were given a
third compressed coreless rolled product. A comparison of this
third study to the second study is observed in Table 6 still
further below.

[0049] Table 6 below, shows that instances of telescoping continued
to decrease when participants were given a third compressed
coreless rolled product and successfully found the central cavity
thereof. Moreover, fewer participants complained of sheets falling
off at the end of the roll or improperly dispensing. Accordingly,
the number of participants that perceived benefits, would change
behavior for said benefits and try/purchase again increased.
