Description
BACKGROUND
[0001] Cleaning tools, such as mops, are commonly used in order to
clean surfaces and other objects found in industry and in
residential settings. Mops typically include an elongated handle
and a mop head attached to the handle. A disposable wipe may be
attached to the mop head, and may be configured in order to pick up
dirt, lint, fluid, and other material from a surface when the mop
head is moved over the surface.
[0002] A disposable wipe may be configured in order to pick up
these materials when the disposable wipe is dry. Alternatively, the
disposable wipe may be configured as a wet wipe in order to pick up
these materials when the disposable wipe is moist to some degree.
The disposable wipe may be packaged in a moistened state, and
applied to the mop head in this same condition in order to
eliminate the need to wet the disposable wipe in proportion for
use. Alternatively, the wet wipe may be packaged in a dry state,
attached to the mop head by the user, and then moisture may be
applied by the user in order to prepare the disposable wipe for
use. Alternatively or additionally, the user may first wet the
surface to be mopped before mopping with the wipe.
[0003] Once the disposable wipe reaches the end of its design life,
the user may remove the disposable wipe from the mop head and
subsequently throw away the disposable wipe. At such time, a new
disposable wipe may be applied to the mop head in order to resume
or start cleaning.
[0004] In order to apply the disposable wipe onto the mop head, the
disposable wipe is typically laid flat on a surface. The mop head
is then positioned in the center of the disposable wipe. Next, the
user will fold the disposable wipe around opposite ends of the mop
head such that the disposable wipe covers the top of the mop head
on opposite ends. At this point, grippers which are located on the
top of the mop head are used in order to affix the disposable wipe
onto the top of the mop head. The disposable wipe is therefore
positioned on the bottom of the mop head, the top of the mop head
on one side of the handle, and on the top of the mop head on the
other side of the handle.
[0005] It is sometimes the case that excessive fluid will be
present on a surface or object that is desired to be cleaned. This
excessive fluid cannot be effectively removed by the disposable
wipe. In this instance, it would be desirable for a user to have a
squeegee in order to effectively remove any excess fluid present.
Due to the construction of mop heads with disposable wipes, a
squeegee cannot be effectively incorporated therein due to the fact
that the disposable wipes cover certain portions of the mop
head.
[0006] The present invention provides for an improved disposable
cleaning apparatus for use with a cleaning tool, and for a mop for
use in cleaning a surface that incorporates both a disposable wipe
and a squeegee blade therein.
SUMMARY
[0007] Various features and advantages of the invention will be set
forth in part in the following description, or may be obvious from
the description.

apparatus that may be used with a cleaning tool. The disposable
cleaning apparatus includes a disposable wipe that is configured
for removable attachment to the cleaning tool. The disposable wipe
is configured for engaging a surface to be cleaned and for removing
unwanted material from this surface. A squeegee blade is attached
to the disposable wipe and is configured for removing excess fluid
from the surface that is to be cleaned. In other embodiments, the
squeegee blade can be attached or removed from the mop head
independently of the wipe.
[0009] The squeegee blade can be positioned on the upper surface of
a mop head, with a portion extending away from the mop head and/or
away from the wipe, such that inversion of the mop head places the
squeegee blade in contact with the floor to provide a squeegee
function in moving or removing water or other fluids.
[0010] The present invention also provides for a disposable
cleaning apparatus as set forth above where the squeegee blade is
made from polyolefin plastic, any deformable plastic, synthetic
rubber, natural rubber, other elastomers, foam materials including
elastomeric or other deformable polymeric foams, and/or a polymer.
In one embodiment, the squeegee blade is a foam that deforms to
substantially conform to a surface being mopped. This is done in
order to obtain enhanced water removal, and optionally for uptake
of water into the foam itself. In another embodiment, a deformable
abrasive foam such as a layer of an open-celled melamine-based foam
can be used as a squeegee, a component of the squeegee, or as a
buffing strip on the mop. Such abrasive foam materials may be
useful in removing marks, such as scuff marks, on flooring or other
surfaces such as walls or ceilings, and in some embodiments can
also provide squeegee functionality.
[0011] Also provided in accordance with the present invention is a
disposable cleaning apparatus as set forth above where the squeegee
blade is attached to the disposable wipe by adhesives, ultrasonic

DETAILED DESCRIPTION
[0031] Reference will now be made in detail to embodiments of the
invention, one or more examples of which are illustrated in the
drawings. Each example is provided by way of explanation of the
invention, and not meant as a limitation of the invention. For
example, features illustrated or described as part of one
embodiment can be used with another embodiment to yield still a
third embodiment. It is intended that the present invention include
these and other modifications and variations.
[0032] The present invention is not limited to the numerical ranges
and limits discussed herein. For example, a range of from about 100
to about 200 also includes ranges from about 110 to about 190,
about 140 to about 160, and from 31 to 45. As a further example, a
numerical limit of less than about 10 also includes a numerical
limit of from less than about 7, less than about 5, and less than
3.
[0033] The present invention provides for a mop and a disposable
cleaning apparatus that incorporate both a disposable wipe and
squeegee blade. Such a combination allows for a device that is
capable of both cleaning a surface, and also removing excess fluid
therefrom. In some embodiments, the squeegee blade may be effective
for other cleaning functions such as abrasive removal of dirt,
deposits, or scuff marks, as set forth hereafter.
[0034] FIG. 1 is a perspective view of a mop 12 used in accordance
with one exemplary embodiment of the present invention. The mop 12
may be used in order to clean any type of surface, for instance the
mop 12 may be used to clean floors, walls, ceilings, and/or objects
such as cabinets, desks, and vehicles.
[0035] The mop 12 includes a handle 32 that is elongated and has a
grip 34 located on one end to provide an area for a user of the mop
12 to hold and move the handle 32. The mop 12 may also be provided
with an additional grip or grips (not shown) at various locations
along the length of the handle 32 with which the user may further
grasp the mop 12. Alternatively, the mop 12 may be configured so
that it does not have any hand grips 34 present thereon. In these
instances, the user may simply grasp the handle 32 in order to
manipulate the mop 12.
[0036] The handle 32 is pivotably connected to a mop head 70. The
pivotable connection between the mop head 70 and the handle 32 is
affected by a pivotable handle attachment 48. The pivotable handle
attachment 48 is shown in greater detail in FIG. 3. The pivotable
handle attachment 48 is configured as a universal joint, allowing
the handle 32 to be pivoted both forwards and backwards with
respect to the mop head 70, and also left and right with respect to
the mop head 70.
[0037] The pivotable handle attachment 48 includes a clevis 50 that
is rigidly attached to the mop head 70. Attachment of the clevis 50
to the mop head 70 may be affected in any manner commonly known to
those skilled in the art. For instance, the clevis 50 may be welded
onto the mop head 70, attached to the mop head 70 with mechanical
fasteners, or may be formed as a single integral piece with the mop
head 70.
[0038] A swivel 54 is disposed within the clevis 50 and is held in
pivotable engagement with the clevis 50 by a pin 52. The swivel 54
is therefore configured in order to allow the handle 32 to pivot in
a back and forth motion with respect to the mop head 70. A sleeve
56 is also included in the pivotable handle attachment 48. The
sleeve 56 is in pivotable engagement with the swivel 54, and a pin
58 is used to place the sleeve 56 into pivotable engagement with
the swivel 54 such that the sleeve 56 rotates in a direction that
is 90 degrees from the direction in which the swivel 54 rotates.
The sleeve 56 and pin 58 therefore allow the handle 32 to rotate in
a left to right direction with respect to the mop head 70.
[0039] The sleeve 56 is configured in order to be both pivotably
attached to the swivel 54 on one end, and rigidly attached to the
handle 32 on an opposite end. The handle 32 may be attached to the
sleeve 56 through a threaded connection, or through any other
connection commonly known to those skilled in the art for instance
mechanical fasteners, welding, or adhesion may be employed.
Alternatively, the handle 32 may be integrally formed with the
sleeve 56.
[0040] In accordance with other exemplary embodiments of the
present invention, the pivotable handle attachment 48 may be
configured differently than disclosed in FIGS. 1-3. For instance,
the pivotable handle attachment 48 may be configured in a manner
similar to the universal joint disclosed in U.S. Pat. No.
4,852,210, the entire disclosure of which is incorporated by
reference in its entirety into the present application for all
purposes. Alternatively, the pivotable handle attachment 48 may be
configured in order to only allow the handle 32 to pivot in one
direction with respect to the mop head 70. Additionally, the mop 12
may be configured so that it does not incorporate a pivotable
handle attachment 48. In this instance, the handle 32 may be
rigidly attached to the mop head 70, and therefore the two
components are not rotatable with respect to one another.
[0041] FIG. 2 shows a detailed side view of the mop 12 of FIG. 1.
Here, the clevis 50 of the pivotable handle attachment 48 is
rigidly attached to a handle attachment surface 36. The handle
attachment surface 36 is located on the side of the mop head 70
which is generally opposite from the side of the mop head 70 which
faces the surface that is to be cleaned. A disposable wipe 14 is
attached to the mop head 70. In the exemplary embodiment shown in
FIGS. 1-3, the ends 26, 28 of the disposable wipe 14 are attached
to the handle attachment surface 36 by adhesive attachments 66, 68.
However, various mechanisms may be employed in order to connect the
disposable wipe 14 to the mop head 70. For instance, instead of
using the adhesive attachments 66, 68 the disposable wipe 14 may be
attached to the mop head 70 by the use of a mechanical attachment,
for instance bolts, pins, gripping elements, frictional elements,
or any other type of mechanical fastener may be employed. For
example, a spring-loaded rod or bar may be configured as a clamp
(not shown) to hold the wipe 14 in place or to secure the squeegee
blade 16. The squeegee blade 16 or a rigid backing plate (not
shown) attached to the squeegee blade 16 may also have protrusions
that extend into retention holes or other receptacles on the mop
head 70 to firmly engage the protrusions and hold the squeegee
blade 16 in place. When a backing plate (not shown) is joined to
the squeegee blade 16, the wipe 14 may be directly attached to the
backing plate, the squeegee blade 14, or neither (e.g., the
squeegee blade 16 and the backing plate may be separately
attachable to the mop head 70 independent of the presence of the
wipe 14). Hook and loop systems may also be used to join the
squeegee blade 16 to the wipe 14 or to the mop head 70 or other
elements. Alternatively, a mechanical attachment may be used in
order to connect the end 26 to the handle attachment surface 36,
while an adhesive attachment is used to connect the other end 28 to
the handle attachment surface 36.
[0042] The mop 12 may also be configured such that only one of the
ends 26, 28 of the disposable wipe 14 is attached to the mop head
70. Still further, the mop 12 may be configured such that a
different portion of the disposable wipe 14 is attached to the mop
head 70, thus allowing the ends 26, 28 of the disposable wipe 14 to
not be attached to the mop head 70. For instance, the intermediate
portion of the disposable wipe 14 may be attached to the mop head
70 at a location on the mop head 70 generally opposite from the
handle attachment surface 36. It is to be understood that the
present invention includes various exemplary embodiments of the mop
12 where the disposable wipe 14 is removably attached to the mop
head 70 by different attachment mechanisms, and at different
locations on the mop head 70.
[0043] As stated, the exemplary embodiment of the mop 12 shown in
FIGS. 1-3 employs a pair of adhesive attachments 66, 68 that retain
the disposable wipe 14 onto the mop head 70 during use of the mop
12. In order to remove or pick up unwanted materials from surfaces,
the user will manipulate the mop 12 such that the mop head 70 is
moved across the surface to be cleaned and the disposable wipe 14
engages the surface and either picks up or removes the unwanted
material. After removing or picking up a certain amount of unwanted
material, the disposable wipe 14 will reach the end of its useful
life and will no longer be able to pick up or remove material, or
will not be able to pick up or remove this material at a desired
rate. At this point, the user of the mop 12 will remove the
disposable wipe 14 from the mop head 70. For instance, the user may
grasp the disposable wipe 14 and pull the disposable wipe 14 from
the mop head 70 such that the holding force of the adhesive
attachments 66, 68 are overcome and the disposable wipe 14 is
separated from the mop head 70. In accordance with other exemplary
embodiments of the present invention, should the disposable wipe 14
be attached to the mop head 70 by a mechanical attachment such as
bolts, pins, or gripper elements, these mechanical attachments may
be disengaged in order to allow for the disposable wipe 14 to be
removed from the mop head 70. For instance, pins holding the
disposable wipe 14 may be removed by the user in order to cause
disengagement. Gripping elements such as those used to engage a
wipe 14 on known mop heads 70 such as SWIFFER.RTM. mops may be
used.
[0044] Once the used disposable wipe 14 has been removed from the
mop head 70, a new disposable wipe 14 may be attached to the mop
head 70 in order to start or resume cleaning of the surface by the
mop 12. In this instance, the new disposable wipe 14 may be
attached to the mop head 70 in a manner similar to the prior
attachment of the used disposable wipe 14 to the mop head 70.
[0045] The adhesive attachments 66, 68 may be configured such that
adhesion is located on the ends 26, 28 of the disposable wipe 14
and is pressed onto the handle attachment surface 36 of the mop
head 70 in order to retain the disposable wipe 14 on the mop head
70. Alternatively, the adhesive attachments 66, 68 may be
configured such that adhesion is present on the handle attachment
surface 36 of the mop head 70, and the ends 26, 28 of the
disposable wipe 14 are pressed thereon and engaged. Still further
exemplary embodiments of the present invention exist where the
adhesive attachments 66, 68 include adhesion on both the handle
attachment surface 36 of the mop head 70, and on the ends 26, 28 of
the disposable wipe 14.
[0046] The mop 12 includes a squeegee blade 16 that is attached to
the disposable wipe 14. The squeegee blade 16 may be used in order
to remove excess fluid that has accumulated onto the surface which
is to be cleaned by the mop 12. In this instance, the squeegee
blade 16 may remove the excess fluid from the surface, allowing for
the disposable wipe 14 to further clean the surface. The squeegee
blade 16 may be attached to the disposable wipe 14 in any manner
commonly known to those skilled in the art. For instance, the
squeegee blade 16 may be attached through ultrasonic bonds, thermal
welds, mechanical fasteners, and/or adhesives such as hot melts and
isocyanates. The squeegee blade 16 may be made out of a material
that is rigid enough to allow the squeegee blade 16 to function,
yet flexible and soft enough to prevent the squeegee blade 16 from
scratching the surface which is to be cleaned. In accordance with
certain exemplary embodiments of the present invention, the
squeegee blade 16 may be made from a polyolefin plastic, any
deformable plastic, synthetic rubber, natural rubber, an elastomer,
foam materials including elastomeric or other deformable polymeric
foams, and the like. Additionally, the squeegee blade 16 may be
made from a material that is either natural or synthetic. The
squeegee blade 16 may be mounted on any portion of the mop head 70,
for instance the squeegee blade 16 may be attached to the front,
back, top, bottom, or side of the mop head 70.
[0047] The squeegee blade 16 shown in the exemplary embodiment in
FIGS. 1-3 is a blade that is essentially straight from one side to
the other. However, in accordance with other exemplary embodiments
of the present invention, the squeegee blade 16 may be variously
designed. For instance, the squeegee blade 16 may be curved,
fluted, ribbed, and/or cross-hatched. Additionally, the surface of
the squeegee blade 16 may be either smooth or textured. FIG. 9
shows an alternative exemplary embodiment of the present invention
in which the squeegee blade 16 has a tip 30 that is curved. The tip
30 has a curved end 18 on one side, and a curved end 20 on an
opposite side. The curved ends 18, 20 are curved towards one
another and define a curved cavity 22. The curved squeegee blade 16
shown in FIG. 9 may be advantageous in certain exemplary
embodiments of the present invention in that fluid may be more
easily transferred across the surface to be cleaned by being
retained in and pushed by the curved cavity 22 of the tip 30.
Additionally, the curved ends 18, 20 of the tip 30 may prevent
fluid from being pushed around the sides of the squeegee blade 16
and hence contacting and saturating the disposable wipe 14.
[0048] The squeegee blade 16 may be made out of either a flexible
or rigid material. Further, the squeegee blade 16 may be either
elastomeric or non-elastomeric. In accordance with one exemplary
embodiment of the present invention, the squeegee blade 16 has a
length from about 0.5 inches to about 4 inches. Additionally, in
accordance with one exemplary embodiment of the present invention
the squeegee blade 16 has a maximum thickness of about 5 mm. Still
further, an alternative exemplary embodiment of the present
invention exists in which the squeegee blade 16 has a maximum
thickness of about 3 mm.
[0049] The exemplary embodiment shown in FIGS. 1-3 therefore allows
for the mop 12 to have the disposable wipe 14 wrap around the mop
head 70 and still provide for an attachment of the squeegee blade
16. Although shown as being attached to the end 26, the squeegee
blade 16 may be attached to any portion of the disposable wipe 14
in accordance with other exemplary embodiments of the present
invention. Additionally, a second squeegee blade 16 may be
employed, and may be attached, for instance, to the other end 28 of
the disposable wipe 14.
[0050] Another exemplary embodiment of the mop 12 is shown in FIGS.
4-6. In this exemplary embodiment of the present invention, the mop
12 is provided with a pivotable handle attachment 48 which is a
ball and socket type attachment. A ball 62 is located at the end of
the handle 32. A socket cap 64 is retained in the mop head 70 by
any means commonly known in the art. The ball 62 is retained within
the socket cap 64 and may rotate therein. As such, the handle 32 of
the mop 12 may be rotated either forward or backward, left or
right, or diagonally with respect to the mop head 70.
[0051] The ball 62 may be retained within the socket cap 64 via a
frictional fit which allows for the user of the mop 12 to rotate
the ball 62 within the socket cap 64 by moving the handle 32.
However, the frictional fit is strong enough to prevent the handle
32 from moving on its own once the user of the mop 12 lets go of
the handle 32. As previously mentioned, the present invention may
employ any type of pivotable handle attachment 48 in accordance
with various exemplary embodiments of the present invention. The
configuration of the pivotable handle attachment 48 shown in FIGS.
4-6 is only one type of pivotable handle attachment 48 which may be
employed, and it is to be understood that the present invention is
not limited to the pivotable handle attachment 48 shown, but may be
of any type.
[0052] The handle 32 is pivotably attached to the handle attachment
surface 36 of the mop head 70 by the pivotable handle attachment
48. A disposable wipe attachment surface 38 is present on the mop
head 70, and a majority of the disposable wipe attachment surface
38 is opposite from the handle attachment surface 36. The
disposable wipe 14 is removably attached to the disposable wipe
attachment surface 38. In this regard, an adhesive attachment 42 is
employed in order to retain the disposable wipe 14 onto the
disposable wipe attachment surface 38. As previously mentioned with
respect to other exemplary embodiments, the disposable wipe 14 may
be attached to the mop head 70 by other mechanisms, and is not
limited to simply being an adhesive attachment. For instance, the
disposable wipe 14 may be attached to the disposable wipe
attachment surface 38 by use of mechanical fasteners such as bolts,
pins, rivets, or gripper elements.
[0053] In the exemplary embodiment shown in FIGS. 4-6, the adhesive
attachment 42 retains the disposable wipe 14 onto the disposable
wipe attachment surface 38 with a sufficient amount of force such
that the disposable wipe 14 is not disengaged from the mop head 70
during normal use of the mop 12. Once the disposable wipe 14
reaches the end of its useful life, a user may grasp the disposable
wipe 14 and disengage the disposable wipe 14 from the disposable
wipe attachment surface 38, therefore breaking or disengaging the
adhesive attachment 42. At such time, a new disposable wipe 14 may
be affixed to the disposable wipe attachment surface 38 in order to
start or resume cleaning with the mop 12.
[0054] In the exemplary embodiment shown in FIGS. 4-6, the squeegee
blade 16 is not attached to the disposable wipe 14. Instead, the
squeegee blade 16 is attached to the handle attachment surface 36
of the mop head 70 by an adhesive attachment 40. The squeegee blade
16 may be attached to the mop head 70 by any mechanism commonly
known in the art. For instance, the squeegee blade 16 may be
attached through the use of adhesives, mechanical fasteners, sonic
welding, or may be integrally formed therewith. As can be seen in
FIG. 5, the squeegee blade 16 is attached to the handle attachment
surface 36 at a location proximate to a leading edge 44 of the mop
head 70. In accordance with other exemplary embodiments of the
present invention, the squeegee blade 16 may be attached to the
handle attachment surface 36 at a location proximate to a trailing
edge 46 of the mop head 70. Still further, a pair of squeegee blade
16 may be employed in accordance with other exemplary embodiments
of the present invention. In such an instance, one of the squeegee
blades 16 may be located proximate to the leading edge 44, and the
other of the squeegee blades 16 may be located proximate to the
trailing edge 46.
[0055] The leading edge 44 is the leading portion of the mop head
70, while the trailing edge 46 is the trailing portion of the mop
head 70 opposite from the leading edge 44. Some users of the mop 12
may move the mop head 70 in a forward and backward motion along the
surface to be cleaned, a motion generally in line with the leading
edge 44 and trailing edge 46.
[0056] Although described as being attached to the handle
attachment surface 36, the squeegee blade 16 may be attached to any
portion of the mop head 70 in accordance with other exemplary
embodiments of the present invention. For instance, the squeegee
blade 16 may be attached to the side of the mop head 70, or may be
attached to the disposable wipe attachment surface 38 in accordance
with other exemplary embodiments. The squeegee blade 16 may be
either permanently attached to the mop head 70, or may be
temporarily attached to the mop head 70 such that the user may
disengage the squeegee blade 16 from the mop head 70. The
attachment of the squeegee blade 16 to the mop head 70 allows for a
user of the mop 12 to use both the squeegee blade 16 and the
disposable wipe 14 without having the squeegee blade 16 interfere
with the operation of the disposable wipe 14.
[0057] The exemplary embodiment shown in FIGS. 4-6 is advantageous
in that the disposable wipe 14 does not wrap around the leading and
trailing edges 44, 46 and contact the handle attachment surface 36.
Elimination of this wrapping around allows for the squeegee blade
16 to be attached to the handle attachment surface 36, and also
eliminates a portion of the disposable wipe 14 which may be wasted
upon wrapping the disposable wipe 14 around the mop head 70.
[0058] The present invention also provides for a disposable
cleaning apparatus 10, one exemplary embodiment of which is shown
in FIG. 7. The disposable cleaning apparatus 10 may be attached to
a mop 12 as discussed with respect to other exemplary embodiments.
The disposable cleaning apparatus 10 includes a disposable wipe 14
that is attached to a squeegee blade 16. The components of the
disposable cleaning apparatus 10 may be configured in the same
manner as discussed with respect to the disposable wipe 14 and
squeegee blade 16 of other exemplary embodiments of the present
invention. A stack 72 of disposable cleaning apparatuses 10 may be
provided as shown in FIG. 8. In this instance, the stack 72 may be
sold to a user of the mop 12, and may be placed into a package such
that the user may remove a single disposable cleaning apparatus 10
when replacement on the mop 12 becomes necessary. Should the
disposable wipe 14 be configured as a wet wipe, the stack 72 may be
contained within a package that keeps the disposable cleaning
apparatuses 10 damp. Alternatively, the stack 72 may be placed
inside of a dry package should the disposable wipe 14 be configured
for operating as a dry wipe, or should it be desirable that the
disposable wipe 14 operate as a wet wipe by being wetted by a user
of the mop 12.
[0059] FIG. 7 shows the disposable cleaning apparatus 10 with a
melamine based foam 76 located on the squeegee blade 16. The
melamine based foam 76 may be used as a cleaning agent in order to
further remove dirt and other unwanted elements from the surface
which is to be cleaned. The melamine based foam 76 has an open
celled, microporous structure that is abrasive when rubbed across
the surface to be cleaned. The melamine based foam 76 may be
configured in order to work when wet. In this regard, the melamine
based foam 76 may be soaked with water or wetted to some degree
prior to being applied by a user to the surface to be cleaned. The
melamine based foam 76 is abrasive in that when rubbed across the
surface, particles of the melamine based foam 76 may break off due
to abrasive contact when removing dirt and other unwanted elements.
Over time, the melamine based foam 76 will be worn down due to
repeated abrasion with the surface. At such time, the disposable
cleaning apparatus 10 may be removed and replaced with a new
disposable cleaning apparatus 10. The melamine-based foam may have
a thickness of about 8 mm or less, about 5 mm or less, about 3 mm
or less, or about 2 mm or less.
[0060] The melamine based foam 76 may be provided on only a portion
of the squeegee blade 16, or may be provide across the entire
surface of the squeegee blade 16, including the tip 30 in various
exemplary embodiments. The melamine based foam 76 may also be
incorporated into the squeegee blade 16 which is on the disposable
wipe 14 attached to the mop 12. In accordance with other exemplary
embodiments of the present invention, the entire squeeze blade 16
on either the mop 12 or the disposable cleaning apparatus 10 may be
made entirely of melamine based foam 76 or comprise one or more
discrete elements made at least in part from melamine-based
foam.
[0061] Principles for manufacturing melamine-based foam are well
known. Melamine-based foams are currently manufactured by BASF
(Ludwigshafen, Germany) under the BASOTECT.RTM. brand name. For
example, BASOTECT.RTM. 2011, with a density of about 0.01
g/cm.sup.3, may be used. Blocks of melamine-based foam for cleaning
are marketed by Procter & Gamble (Cincinnati, Ohio) under the
MR. CLEAN.RTM. brand name, and under the CLEENPRO.TM. name by LEC,
Inc. of Tokyo, Japan. Melamine-based foam is also marketed for
acoustic and thermal insulation by many companies such as American
Micro Industries (Chambersburg, Pa.). The foam may be heat treated
and compressed to increase its density.
[0062] Principles for production of melamine-based foam are
disclosed by H. Mahnke et al. in EP-B 071 671, published Dec. 17,
1979. According to EP-B 017 671, they are produced by foaming an
aqueous solution or dispersion of a melamine-formaldehyde
condensation product which comprises an emulsifier (e.g., metal
alkyl sulfonates and metal alkylaryl sulfonates such as sodium
dodecylbenzene sulfonate), an acidic curing agent, and a blowing
agent, such as a C5-C7 hydrocarbon, and curing the
melamine-formaldehyde condensate at an elevated temperature. The
foams are reported to have the following range of properties:
[0063] a density according to DIN 53 420 between 4 and 80 grams per
liter (g/l), corresponding to a range of 0.004 g/cc to 0.08
g/cc;
[0064] a thermal conductivity according to DIN 52 612 smaller than
0.06 W/m .degree. K.;
[0065] a compression hardness according to DIN 53 577 under 60%
penetration, divided by the density, yielding a quotient less than
0.3 (N/cm.sup.2)/(g/l), and preferably less than 0.2
(N/cm.sup.2)/(g/l), whereby after measurement of compression
hardness the thickness of the foam recovers to at least 70% and
preferably at least 90% of its original thickness;
[0066] an elasticity modulus according to DIN 53 423, divided by
the density of the foam, under 0.25 (N/mm.sup.2)/(g/l) and
preferably under 0.15 (N/mm.sup.2)/(g/l);
[0067] a bending path at rupture according to DIN 53 423 greater
than 6 mm and preferably greater than 12 mm;
[0068] a tensile strength according to DIN 53 571 of at least 0.07
N/mm.sup.2 or preferably at least 0.1 N/mm.sup.2; and
[0069] by German Standard Specification DIN 4102 they show at least
standard flammability resistance and preferably show low
flammability.
[0070] U.S. Pat. No. 4,666,948, "Preparation of Resilient Melamine
Foams," issued May. 19, 1987 to Woerner et al., discloses other
melamine-based foams that may be used in the present invention.
U.S. Pat. No. 6,503,615, issued Jan. 7, 2003 to Horii et al.,
discloses a wiping cleaner made from an open-celled foam such as a
melamine-based foam, the wiping cleaner having a density of 5 to 50
kg/m.sup.3 in accordance with JIS K 6401, a tensile strength of 0.6
to 1.6 kg/cm.sup.2 in accordance with JIS K 6301, an elongation at
break of 8 to 20% in accordance with JIS K 6301 and a cell number
of 80 to 300 cells/25 mm as measured in accordance with JIS K 6402.
Melamine-based foams having such mechanical properties can be used
within the scope of the present invention.
[0071] Related foams are disclosed in U.S. Pat. No. 3,093,600 with
agents present to improve the elasticity and tear strength of the
foam. Melamine-based foams are also disclosed in British patent GB
1443024, issued Jul. 21, 1976. The entire disclosure of U.S. Pat.
No. 6,608,118, issued Aug. 19, 2003 to Kosaka, et al. is
incorporated by reference herein in its entirety.
[0072] The melamine-based foam may be provided as a thin, flexible
layer joined to a reinforcing web of tissue, nonwoven material,
fabric, or other materials, including those disclosed in commonly
owned copending application, Ser. No. unknown, "Multi Purpose
Cleaning Product Including a Foam and a Web" by Chen et al., filed
on Dec. 22, 2003, the same day as the present document.
[0073] An alternative exemplary embodiment of the disposable
cleaning apparatus 10 is shown in FIG. 10. Here, the squeegee blade
16 has a plurality of ribbed features 24 located thereon. The
ribbed features 24 may assist in the removal of fluid from the
surface to be cleaned by providing for a channel between the ribbed
features 24 which allows for the transport of fluid by the squeegee
blade 16. The ribbed features 24 define a plurality of cavities 74.
The disposable wipe 14 may be retained through adhesion to the
surface of the squeegee blade 16 proximate to the cavities 74.
Alternatively, the disposable wipe 14 may be attached across the
surface of the squeegee blade 16 from one end to the other. As
such, the squeegee blade 16 used in either the disposable cleaning
apparatus 10 or the mop 12 may be made in various shapes and
configurations in accordance with various exemplary embodiments of
the present invention.
[0074] The user of the mop 12 may move the handle 32 such that the
mop head 70 is inverted, allowing for the squeegee blade 16 to
contact the surface to be cleaned and remove excess fluid
therefrom. For instance, a user may turn the mop head 70 upside
down in order to reposition the squeegee blade 16 such that it
contacts the surface to be cleaned. In this instance and in other
related cases, a portion of the squeegee blade 16 after inversion
can be directly below the mop head 70 such that the mop head 70
applies leverage on the squeegee blade 16 to force the tip 30 of
the squeegee blade 70 to press downward against the surface to be
cleaned for effective contact. Alternatively, the squeegee blade 16
may be configured such that it extends to the surface to be cleaned
while the mop head 70 is in the positions shown in FIGS. 2 and 5.
In this instance, the user of the mop 12 may move the handle 32
such that the mop head 70 is repositioned and the squeegee blade 16
does not contact the surface to be cleaned. At such time, the user
may move the mop head 70 across the surface to be cleaned in order
for unwanted materials to be picked up or removed by the disposable
wipe 14. Alternatively, the mop 12 may be configured such that both
the squeegee blade 16 and the disposable wipe 14 simultaneously
engage the surface to be cleaned.
[0075] As mentioned, the squeegee blade 16 and/or the disposable
wipe 14 may be attached to the mop head 70 and/or one another
through several different mechanisms. For instance, the attachment
may be through pressure-sensitive adhesives, hook and loop type
fasteners, gecko-like fasteners, and/or activatable adhesives.
Gecko-like adhesives are discussed by Kelly Autumn et al.,
"Evidence for van der Waals Adhesion in Gecko Setae," Proceedings
of the National Academy of Sciences of the United States of
America, Vol. 99, No. 19, pp. 12,252-12,256 (Sep. 17, 2002), and by
Robert J. Full et al., "Adhesive Microstructure and Method of
Forming the Same," WO 01/49776, published Jul. 12, 2001. Both of
the aforementioned publications are incorporated by reference
herein in their entireties.
[0076] The mop 12 and/or disposable cleaning apparatus 10 may be
used to clean any type of surface. For instance, the mop 12 and
disposable cleaning apparatus 10 may be used in order to clean
windows, cars, and porcelain surfaces such as showers or toilets.
Further, the disposable cleaning apparatus 10 may be used in order
to clean dishes, used as a skin-cleansing tool, and used as a
covering on a scrubby pad or sponge. As such, the mop 12 and/or
disposable cleaning apparatus 10 may be used in a variety of
applications in order to clean a variety of surfaces.
[0077] The disposable wipe 14 may be configured in order to have a
variety of properties. For instance, the disposable wipe 14 may be
an electrostatically treated web in accordance with one exemplary
embodiment of the present invention. The disposable wipe 14 may be
a dry wipe or a wet wipe. Further, the disposable wipe 14 may be
made of a high wet strength tissue web, or may be made from
laminates of non-woven webs and tissue webs. The disposable wipe 14
may be elastomeric wipe that is stretchable or extendable, or may
alternatively be a non-stretchable wipe. The disposable wipe 14 may
also include encapsulated cleaning agents or anti-microbial agents.
Additionally, the disposable wipe 14 may be configured in order to
contain an aroma agent that will deliver a particular scent to the
surface to be cleaned.
[0078] Further, the mop head 70 itself may be adapted in order to
deliver an agent or active ingredient for enhancing the cleaning of
the surface, removing odors from the surface, adding a scent to the
surface, adding an anti-microbial agent to the surface, or
providing some type of surface treatment to the surface to be
cleaned. The surface treatment applied to the surface to be cleaned
may be a wax, a polish, buffing agents, buffering agents, an oil
removal agent, an acidic or basic ingredient, a grout cleaning
agent, a ceramic or tile cleaning agent, an anti-mildew agent,
and/or bleach. The agent delivered by the mop head 70 may be a dry
material such as a powder, for instance baking soda, abrasive grit,
miticide, or a zeolite. Further, the agent delivered by the mop
head 70 may be a wet agent such as a surfactant, a perfumed
solution, a solution of cyclodextrin or other odor absorbing agent,
an anti-microbial agent, a preservative agent, an oil or polish,
water, a window cleaner, and/or an indicator solution that
indicates the presence of bacteria or other harmful agents.
Additionally, the agent delivered by the mop head may be a gaseous
agent such as an aroma, a volatile compound, and/or an
anti-microbial gas. In accordance with one exemplary embodiment of
the present invention, the mop head 70 may deliver a nanoemulsion
to the surface that is to be cleaned.
[0079] Although discussed as being delivered by the mop head 70, it
is to be understood that the present invention includes various
exemplary embodiments where the aforementioned types of agents or
active ingredients that were discussed as being delivered by the
mop head 70 may also be configured in order to be delivered by the
disposable wipe 14. Further, the aforementioned agents or active
ingredients may be delivered by a combination of both the mop head
70 and the disposable wipe 14 in accordance with other exemplary
embodiments of the present invention.
[0080] Further exemplary embodiments of the present invention are
described below as Examples 1-4:
EXAMPLE 1
Squeegee Blade attached to a Wet Disposable Wipe
[0081] The mop 12 may be configured to use a disposable wipe 14
that is a SWIFFER.TM. wet wipe (SWIFFER.RTM. Wet Cloths) made by
the Procter & Gamble Company located at 1 or 2, Procter &
Gamble Plaza Cincinnati, Ohio 45201. The wipe measures about 25
cm.times.21 cm. The wipe 14 was dried at room temperature. A
3.2-centimeter by 23-centimeter strip of 2-millimeter thick foam
(Darice Foamies, Item #1144-22, UPC 082676159909, Darice Inc.,
Strongsville, Ohio.) was attached to the dried wipe using
25.4-millimeter wide two-sided tape (23 cm long). The tape was
placed along a front edge of the foam strip, leaving a nearly
7-millimeter width of the foam unattached to the cloth. The foam
strip was located with a first edge proximate to a first edge of
the cloth, and the second edge being remote from the edge of the
cloth, with the second edge being proximate to the unattached
region of the foam strip (i.e., the unattached edge of the foam
strip was remote from the first edge of the cloth). The direction
traversed by the first edge of the cloth corresponded to the major
axis of the cloth, which is intended to be aligned with the
cross-direction of the mop. The first edge of the foam strip as
attached was about 2.9 cm from the first edge of the cloth and
centered with respect to the 25-cm width of the cloth, with the
unattached portion of the foam extending toward the interior of the
sheet. The floor contacting area of the cloth, when mounted on the
mop head, is about 9.5 cm by 25 cm. The cloth with the foam strip
was then attached to the mop head by pressing the cloth into four
gripping sections of the mop head, with the foam strip on the top
portion of the mop head, oriented toward the front, with the
unattached section of the foam extending forward from the body of
the mop head and away from the cloth to form a flexible squeegee
blade 16.
EXAMPLE 2
Squeegee Blade attached to a Dry Disposable Wipe
[0082] The mop 12 is constructed exactly like Example 1 above;
except for the replacement of the wet disposable wipe 14 with a dry
disposable wipe 14. The dry disposable wipe 14 used is a
SWIFFER.TM. dry wipe made by the Procter & Gamble Company
located at 1 or 2, Procter & Gamble Plaza Cincinnati, Ohio
45201. The dry disposable wipe 14 measures about 22 cm by 28 cm.
The first edge of the foam squeegee blade 16 was mounted about 3.2
cm from the first edge of the dry wipe 14.
EXAMPLE 3
Squeegee Blade attached with Hook and Loop Fastener
[0083] The mop 12 employs a hook and loop type fastener made by
Hobby Shop Hook & Loop Fastener Set, UPC number
1402700039107091, and distributed by Tool & Supply of New
England Inc., Wilmington, Del. 19899; V #267240; Item #76546. The
hook fastener of the hook and loop type fastener measures 0.625
inches.times.9 inches, and has a self-adhesive attachment.
[0084] The disposable wipe 14 is either a wet wipe or a dry wipe as
discussed above in Examples 1 and 2. The squeegee blade 16 is a
foam as discussed in Example 1 and measures 1.9 cm by 23 cm. The
squeegee blade 16 is attached along one edge to the self-adhesive
attachment of the hook fastener, leaving approximately 0.3 cm of
the squeegee blade 16 exposed for contact with the floor. The
disposable wipe 14 is attached to the mop head 17, and the squeegee
blade 16 is installed on top of and along the leading edge 44 of
the mop head 70. The squeegee blade 16 protrudes slightly from the
mop head 70. Due to the hook and loop type fastener, the squeegee
blade 16 is detachable from the mop head 70.
EXAMPLE 4
Squeegee Blade attached with a Plastic Strip
[0085] The mop 12 employs a squeegee blade 16 made of the foam
described in Example 1, and a disposable wipe 14 as described in
Examples 1 or 2. A strip of foam, as above, was cut to dimensions
of 1.3 cm.times.20 cm and attached with a strip of two-sided
adhesive tape to a rigid polyethylene strip with dimensions of 4.4
cm.times.20 cm, with a ledge about 7 mm wide of foam remaining
unattached and extending beyond the edge of the polyethylene strip
about 2 mm thick such that the foam could serve as a squeegee blade
16 that extends away from the mop head 70. The polyethylene strip
had two mushroom-shaped protrusions with centers about 16.5 cm
apart, suitable for engaging into the gripping regions (retention
holes) of the mop head 70 to hold the strip in place on the top of
the mop head. The squeegee assembly (foam joined adhesively to the
polyethylene strip) can be installed on the mop head 70 after the
wipe 14 is already in place, or at the same time as the wipe 14 is
attached with the protrusions serving to push the sheet into the
retention holes of the mop head 70. The squeegee blade 16 and/or
the polyethylene strip can help to secure the disposable wipe 14 to
the mop head 70. The strip of adhesive tape used to join the foam
to the polyethylene was about 6 mm wide and about 20 cm long. The
rear edge of the plastic strip (remote from the foam) had a portion
of the plastic removed to allow room for the mop handle 32. The
removed area is approximately 4.4 cm wide.times.1.2 cm deep,
centered on the edge of the plastic strip. The resulting assembly
comprised a foam-based squeegee blade 16 with a rigid backing plate
(the polyethylene strip) mounted to the mop head 70 and in contact
with the wipe 14. When the mop head 70 was inverted, the squeegee
blade 16 was particularly effective in removing water.
[0086] It should be understood that the present invention includes
various modifications that can be made to the exemplary embodiments
of the mop 12 and/or disposable cleaning apparatus 10 as described
herein as come within the scope of the appended claims and their
equivalents.
