Description
PRIORITY INFORMATION
[0001] This application is a continuation of U.S. application Ser.
No. 11/726,960, filed Mar. 23, 2007, which claims the benefit of
U.S. Provisional Application No. 60/856,495, filed Nov. 3,
2006.
TECHNICAL FIELD
[0002] Embodiments of the present invention relate to adhesive
covers for various types of devices, such as electronic devices. In
particular, some embodiments relate to customized adhesive covers
and methods for making the same.
DESCRIPTION OF THE RELATED ART
[0003] Many devices look identical or nearly identical to other
devices. Not only do different models manufactured by the same
company often times look the same, but so do models made by
different companies. For example, the popular Motorola RAZR V3
model looks the same as the Motorola RAZR V3c model. In addition,
the Motorola RAZR V3 model (which is a flip-top type mobile phone)
looks similar to other flip-top type mobile phones. As another
example, the colors and shapes of laptops may vary to some extent;
nevertheless, most laptop computers look nearly the same as every
other laptop computer.
[0004] Because devices (e.g. mobile phones and laptop computers)
are integral with the daily lives of their users, there is a desire
to customize or personalize such devices. In response, some
manufactures have started making such devices in different colors.
However, the number of different colors tends to be limited. In
addition, many users believe that simply changing a color is not
enough of a personalization/customization.
BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTION
[0005] The present invention relates to adhesive covers (a.k.a.
"skins") for various types of devices, such as electronic
devices.
[0006] According to embodiments of the present invention, adhesive
covers are provided that may be customized/personalized to the
tastes of the owner. Embodiments may also have a non-permanent
adhesive layer on its bottom surface so that a user can easily
reposition or remove the adhesive cover from an electronic device
to which it was applied. In some embodiments, a layer of an
adhesive cover can be pre-treated to facilitate digital printing
thereon.
[0007] In addition, embodiments of adhesive covers may protect
electronic components from water and moisture as well as bumps,
scratches and the like. Further, adhesive covers can be fashioned
to not interfere or interfere minimally with the functionality of
electronic device. In this manner, the adhesive covering may be
useful for protecting electronic devices such as cell phones and
aiding in company phone identification, phone re-branding,
enterprise advertising and promotion, and special events
marketing.
[0008] According to one embodiment of the present invention, an
adhesive cover capable of adhering to a surface of an electronic
device is provided. The adhesive cover has a top over laminate
layer. A middle layer is adhered to the top layer. The middle layer
can be vinyl or urethane with a design applied thereto. A bottom,
non-permanent adhesive layer is adhered to the middle layer. The
bottom layer can be used to adhere the adhesive cover to a device's
housing in a non-permanent fashion.
[0009] According to another embodiment of the present invention, a
method of producing an adhesive cover adapted to be adhered to one
or more surfaces of an electronic device is provided. The method
includes corona treating a middle layer and coating the middle
layer with a primer. A design is applied to the middle layer. The
middle layer is also sandwiched between a top laminate layer and a
bottom non-permanent adhesive layer. The adhesive cover can be
contoured to cover or partially cover one or more surfaces of an
electronic device.
[0010] According to a further embodiment of the present invention,
an adhesive cover is provided that includes a first mylar layer
having a design applied to a side of the mylar layer. A second
layer is adhered to the image side of the mylar layer. The second
layer can be a vinyl or polyolefin material. A third non-permanent
adhesive layer is adhered to the second layer. The third layer can
be transfer tape. The cover is contoured to cover or partially
cover one or more sides of an electronic device.
[0011] According to yet another embodiment of the present
invention, an adhesive cover capable of adhering to a surface of an
electronic device is provided. The adhesive cover has first, second
and third layers adhered together. The first layer can be a
thermoplastic urethane, the second layer can be a fabric material
and the third layer can be a non-permanent adhesive tape. The
adhesive cover is shaped to cover or partially cover one or more
sides of an electronic device.
[0012] Other features and aspects of the invention will become

intended to illustrate various embodiments of the invention that
can be understood and appropriately carried out by those of
ordinary skill in the art.
DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE INVENTION
[0023] Although the following description of exemplary embodiments
are directed to adhesive covers for electronic devices, it is
understood that the adhesive covers of the present invention may be
applied to the housing of any type of device wherein customization
may be desired. In one embodiment, the adhesive covers as described
herein may provide protection to electronic components from water
and moisture as well as bumps, scratches and the like. Further, the
adhesive covers can be fashioned to not interfere or interfere
minimally with the functionality of an electronic device. The
adhesive covers may also be customized/personalized to the tastes
of the owner. In this manner, the adhesive covering may be useful
for both personalizing and protecting electronic devices, such as
mobile phones, and aiding in company identification, re-branding,
enterprise advertising and promotion, and special events
marketing.
[0024] As used herein, the term "electronic device" refers to any
electronic device known in the art, for example, but not limited to
electronic communication devices such as mobile telephones,
personal display assistants (PDAs), pagers, radios, two-way radios,
CBs, satellite radios, palm-pilots, MP3 players, music, video and
audio devices, including but not limited to portable music, video
and audio devices, electronic organizers, remote controls for
electronic devices, and the like. Other electronic devices, for
example, include electronic gaming systems, computers, laptops,
cameras, Global Positioning Satellite (GPS) receivers, Compact Disc
(CD) players, DVD players, television recording devices, such as
TiVo.RTM., and monitors are also meant to be included within the
scope of the term "electronic device."
[0025] Referring now to the drawings, FIGS. 1A and 1B illustrate
respective front 102 and back portions 104 of an exemplary adhesive
cover 100 for mobile telephones, in accordance with one embodiment
of the present invention. The adhesive cover 100 is contoured to
conform to front and back sides of a mobile phone.
[0026] FIG. 2 illustrates a further embodiment of an adhesive cover
200 adhered to a front portion of a mobile telephone 202, for
example, a Motorola RAZR V3 mobile telephone. A corner 204 of the
adhesive cover 200 is peeled back to illustrate a removable feature
of the adhesive cover 200, in accordance with one embodiment of the
present invention, and will be explained in further detail below.
In addition, the embodiment 200 has a customized image formed
thereon, which is also explained in further detail below.
[0027] As shown in FIGS. 1A and 1B, in one embodiment, the adhesive
cover 100 is cut, shaped and sized to substantially match the
surface contours of an electronic device to which it may be
adhered. Furthermore, the adhesive cover does not interfere with
the functionality of the electronic device. For example, the front
portion 102 includes a central aperture 106 so that the cover 100
does not block the mobile phone's display screen. Similarly, a top
aperture 108 can be provided so that the cover 100 does not
interfere with a mobile phone's camera lens. Additionally, if the
adhesive cover 100 is designed to be used with the Motorola RAZR V3
phone, for example, the front portion 102 can include two separate
pieces: a top piece 110 and a bottom piece 112. The top piece 110
can substantially cover a flip-top portion of the phone and the
bottom piece 112 can substantially cover a remaining surface of the
front of the phone that is not part of the flip-top portion.
[0028] Shown in FIG. 1B, the back portion 104 includes a lower
aperture 114 so that the adhesive cover 100 does not cover the
phone's speaker. In addition, the back portion 104 comprises two
separate pieces: a top piece 116 and a bottom piece 118. The two
pieces 116 and 118 are separate so that a user can remove a back
panel of the phone to gain access to the phone's battery. Had the
back portion 104 been a single piece covering the entire back of a
Motorola RAZR V3i, a user would have to either remove the back
portion 104 from a phone or cut the back portion 104 prior to
gaining access to or removing the back panel of the phone.
[0029] As discussed above, the adhesive cover 100 may comprise one
or more pieces as well as various apertures so that it does not
substantially affect the functionality of an electronic device to
which the adhesive cover 100 is adhered. In other embodiments, tear
away sections, peel away sections, punch out sections may also be
provided to permit parts of the electronic device to function.
These parts of the electronic device can include, but are not
limited to, controls, dials, buttons, displays, camera lenses,
antennas, input/output jacks, microphones, speakers, signal ports
(e.g. infrared signal ports), hardware connector ports, software
connector ports, battery compartments and the like of the
electronic device to be surrounded. Similarly, the adhesive cover
100 may also be affixed over or around one or more of the
above-mentioned electronic device parts without substantially
affecting the function of the parts.
[0030] The apertures, tear-away sections, peel away sections, punch
out sections and the like may be created by any suitable process
known in the art, for example, a die cutting process, laser cutting
process, a contour cutter or any other cutting device or process
that is capable of cutting a set pattern or outline for the
electronic device.
[0031] Furthermore, embodiments of adhesive covers of the present
invention may comprise dimensions such that the adhesive covers are
capable of covering one or more sides or faces of an electronic
device. For example, in some embodiments, an adhesive cover covers
a portion of a single side of an electronic device. In other
embodiments, an adhesive cover covers multiple sides of an
electronic device. In further embodiments, an adhesive cover covers
a face of an electronic device, such as a face of a mobile phone.
In other embodiments, the adhesive cover can have dimensions such
that it can be wrapped around one or more sides of the electronic
device.
[0032] As described with reference to FIG. 2, in accordance with
various embodiments of the present inventions, adhesive covers may
be customized or personalized by including one or more designs. As
used herein, the term "design" refers to colors, text, names,
company brands, slogans, images, patterns, designs, graphics,
photographs, logos, advertisements, or any combination thereof.
Designs may be provided by a customer or person who wishes to
customize an electronic device or may be provided by a manufacturer
of the adhesive cover or other entity. Any suitable method of
transferring designs to the adhesive cover may be employed, e.g.
printing, screen-printing, silk screening, flocking, chemically
burning, etc.
[0033] FIG. 3 is a cross-sectional view of an adhesive cover 300 in
accordance with one embodiment of the present invention. The
adhesive cover 300 can comprise a number of layers: a release liner
or backing strip 302, a first adhesive layer 304, a base layer 306,
a primer layer 308, a print layer 310, a second adhesive layer 312
and an overlaminate layer 314.
[0034] The release liner 302 can function to cover the first
adhesive layer 304 until a user decides to apply the adhesive cover
300 to a device. In other words, the release liner 302 can protect
the first adhesive layer 304 from engaging surfaces or picking up
dust while the adhesive cover 300 is not in use, for example. It
may also be desirable to have the release liner 302 cover the first
adhesive layer 304 while the adhesive layer 300 is being shipped to
a user and when a user takes the adhesive cover 300 out of its
packaging. A user can then pull the release liner 302 away from the
remaining portion of the adhesive cover 300, thereby exposing the
first adhesive layer 304. The user can then adhere the adhesive
cover 300 to a device by applying the exposed adhesive layer 304 to
the device.
[0035] With further reference to FIG. 3, the first adhesive layer
304 can be an adhesive material capable of adhering the adhesive
cover 300 to a device. In one embodiment, the first adhesive layer
304 is chosen such that the adhesive cover 300 is non-permanent or
removable from a device so that it can be repositioned after being
affixed thereto. For example, the adhesive cover 300 may be peeled
off a device when a user so desires. It may also be desirable that
the adhesive layer 304 has a characteristic of not leaving a sticky
or tacky residue on a device after a user removes the adhesive
cover 300 from the device to which it was adhered. In an
alternative embodiment, the first adhesive layer 304 may be
permanent or essentially permanent, such that the adhesive cover
300 is non-removable or essentially non-removable from a device
after being affixed thereto. In such an alternative embodiment, the
adhesive cover 300 may be affixed over the top of one or more
previously affixed adhesive covers.
[0036] The first adhesive layer 304 can also have a visible or
invisible pattern (not shown) formed therein. The pattern can
function to channel air out from underneath the adhesive cover 300
when the adhesive cover 300 is applied to a device to avoid
undesirable effects of air bubbles trapped between a device and the
adhesive cover 300. Suitable adhesives may be obtained from a
variety of suppliers known in the art, for example, 3M and Avery
Dennison. It has been found that transfer tape or pressure
sensitive adhesive (a.k.a. PSA) supplied by 3M are suitable
adhesives.
[0037] With further reference to FIG. 3, the base layer 306 can
function as a foundation for the adhesive cover 300. The base layer
306 can also provide a desired stiffness to the adhesive cover 300.
The base layer 306 can also be part of the design when, for
example, the base layer 306 is of a desired color or texture. A
number of different materials can be used as the base layer 306,
including a PVC vinyl, a polyolefin, or other synthetic material,
such as polyester, urethane, lexan and polycarbonate. Other
suitable materials known in the art can also be used.
[0038] As shown in FIG. 3, the primer layer 308 can be applied to
the top surface of the base layer 306. In general, the primer layer
308 can function to improve "printability" (e.g. ink absorption) of
the base layer 306, thereby facilitating acceptance of the print
layer 310 to the base layer 306. In one embodiment, corona treating
removes impurities, such as oils and then primer is optionally
applied. It has been found that a suitable primer is Digiprime 5000
supplied by Michelman Co. In other embodiments, the primer layer
and/or corona treatment may be omitted.
[0039] The print layer 310 can include one or more design
materials, such as ink or the like, for forming a design in the
adhesive cover 300. In accordance with various embodiments, the
print layer 310 can be applied to the base layer 306 (facilitated
by the primer layer 308) in a variety of ways, including by
digitally printing, silk-screening or screen-printing. FIG. 3 shows
the print layer 310 extending across the length of the adhesive
cover 300. However, it is also understood that the print layer 310
need not extend across the entire length of the adhesive cover 300,
since the print layer 310 need only reside at locations where, for
example, a design is present. If ink is used to print a design,
various inks may be used, including glow-in-the dark ink or
ultra-violet transparent ink, metal ink or other inks known in the
art.
[0040] The second adhesive layer 312 can function to bond the
overlaminate layer 314 to other layers of the adhesive cover 300.
The second adhesive layer 312 can be either permanent or
non-permanent. In addition, the second adhesive layer 312 can be
transparent (i.e. clear), semi-transparent or opaque. Suitable
adhesives that can be used as the second adhesive layer 312 are
available from a variety of suppliers known in the art, including
3M Company located in St. Paul, Minn.
[0041] In general, the overlaminate layer 314 can provide an
outside protective layer to the adhesive cover 300. In one
embodiment, the overlaminate layer 314 is a calendared or cast PVC
vinyl film. In another embodiment, the overlaminate layer is a
polyolefin material. It has been found that a polyolefin material
may be preferred over a PVC vinyl material for environmental
disposal reasons, as many PVC vinyl materials are known to contain
lead. Other suitable materials may also be used as are known by
those skilled in the art. Furthermore, the overlaminate 314 can be
transparent, semi-transparent or opaque. The overlaminate layer 314
may also be colored and have patterns formed in or on the layer
314. In one embodiment, the overlaminate layer 314 and the second
adhesive layer 312 are both transparent so that the print layer 310
and/or base layer 306 are visible through the overlaminate layer
314 and the second adhesive layer 312.
[0042] A resin dome can also be applied to the adhesive cover 300.
In general, a resin dome can provide a "puffy" or raised appearance
to the adhesive cover. In one embodiment, the resin dome is applied
on top of the overlaminate layer 314. In another embodiment, the
resin dome is the overlaminate layer 314.
[0043] In one embodiment, the base layer 306 can be completely or
partially transparent. Suitable materials for providing a
transparent base layer 306 are well-known. In such a manner, the
adhesive cover 300 can be completely or partially transparent so
that, when adhered to a device, some or all of the housing of the
device is visible through the adhesive cover 300. For example, in
an embodiment where the base layer 306 is transparent, the print
layer 310 comprises a black design and the adhesive cover 300 is
applied to a device having a red colored housing, a person looking
at the device would see the red housing overlaid by the black
design.
[0044] It is understood that various modifications to the adhesive
cover 300 may be made without departing from the spirit of the
present invention. For example, additional layers may be added and
some of the layers depicted in FIG. 3 may be removed. Additionally,
the primer layer 308 need not be included if a printing method is
used that sufficiently binds the printing layer 310 to the base
layer 306 without the use of the primer layer 308. Furthermore, the
printing layer 310 need not be included if, for example, it is
desired not to print a design in the adhesive cover 300.
Furthermore, the release liner 302 may not be needed if a
manufacturer applies the adhesive cover 300 to a device soon after
the adhesive cover 300 is made, for example.
[0045] With reference to FIG. 4, decorative pieces 420a, 420b, 420c
can be added to the adhesive cover 300 in accordance with one
embodiment of the present invention. Decorative pieces 420 can be
any object that attracts attention to the adhesive cover. Examples
of decorative pieces 420 can include swarofsky crystals,
rhinestones, beads, precious metals, plastic pieces and the like.
The decorative pieces 420 can be provided in a variety of shapes
and colors and can be arranged in any desired pattern, such as
symbol or textual patterns. For example, FIG. 5 shows a plurality
of decorative pieces 420 positioned onto an embodiment of an
adhesive cover 500 in the pattern of a star.
[0046] The decorative pieces 420 can have a non-permanent or
permanent adhesive layer 422 on their bottom surface so that they
adhere to the surface of the adhesive cover 300. In one embodiment,
the adhesive layer 422 is permanent so that the decorative pieces
420 do not come off when a user inserts a device into a pocket, for
example. The decorative pieces 420 can be attached to the adhesive
cover 300 during manufacturing of the adhesive cover 300, or the
decorative pieces 420 can be provided to a user separately for the
user to place on the adhesive cover 300 as desired. In one
embodiment, the adhesive cover 300 is provided to a user with a
pre-printed pattern (not shown) designating where decorative pieces
420 are to be placed. A user may then apply decorative pieces 420
to the adhesive cover 300 in accordance with the pre-printed
pattern. The pre-printed pattern can comprise, for example, a
plurality of dots; each dot designating a location for a user to
place a decorative piece.
[0047] FIG. 6 is a cross-sectional view of a further embodiment of
an adhesive cover 600. The adhesive cover 600 includes an outer
layer 630, which can be made of a flocked fabric or other synthetic
or natural weave material. One suitable flocked fabric material is
commercially available from Fiberlok, Inc. located in Fort Collins,
Colo., United States, and sold under the trademark LextraMax.
Alternatively, the outer layer can be a synthetic film having, for
example, a wood grain, metallic, carbon or leather appearance. The
outer layer 630 can also be natural panel, wood or the like.
[0048] Designs can be applied to the flock transfer material by
digital printing, silk-screening and screen-printing, for example.
One such screen-printing technique is described in U.S. Pat. No.
6,977,023, which issued on Dec. 20, 2005 and is entitled "SCREEN
PRINTED RESIN FILM APPLIQUE OR TRANSFER MADE FROM LIQUID PLASTIC
DISPERSION," the contents of which are incorporated herein by
reference.
[0049] The adhesive cover 600 shown in FIG. 6 also includes a base
layer 606. The base layer 606 can generally function to provide a
desired stiffness or flexibility to the adhesive cover 600, prevent
the adhesive cover 600 from tearing and/or maintain the overall
structure of the adhesive cover 600. The base layer 606 can be, for
example, made of TPU/polyurethane, mylar or other suitable
synthetic or natural material that provides a desired flexibility.
As shown in FIG. 6, the base layer 606 is adhered to the outer
layer 630 by an adhesive layer 632, which may be a permanent or
non-permanent adhesive.
[0050] Further to FIG. 6, a release liner 602 and adhesive layer
604 are adhered to a bottom side of the base layer 606. To
facilitate boding, a further adhesive layer 634 and a carrier layer
636 are sandwiched between the adhesive layer 604 and the base
layer 606. The carrier layer 636 preferably facilitates holding the
adhesive layers 604 and 634 together. Any suitable carrier may be
used, such as a polyester material, other synthetic material or
other carrier known in the art.
[0051] As illustrated in FIG. 7, decorative pieces 420a, 420b and
420c can also be applied to the adhesive cover 600 in a similar
fashion as that described above with reference to FIGS. 4 and
5.
[0052] A cross-sectional view of an additional embodiment of an
adhesive cover 800 is illustrated in FIG. 8. The adhesive cover 800
has a release liner 802, an adhesive layer 804 and a base layer
806, which can be the same as the release liner 302, the adhesive
layer 304 and the base layer 306, respectively, shown in FIG.
3.
[0053] With further reference to FIG. 8, an outer layer 844 is
located on a top surface of the adhesive cover 800. The outer layer
844 can be a colored or clear film made of, for example,
lenticular, polyester, polycarbonate or other synthetic material.
In the embodiment 800, the outer layer 844 can have a design
affixed to its inner surface, as described in more detail
below.
[0054] A primer layer 810 is applied to an underside of the outer
layer 844. In one embodiment, the outer layer 844 is made of a
lenticular material and a lenticular pattern is printed to the
bottom surface of the outer layer 844. The primer layer can be the
same as the primer layer 308, described with reference to FIG. 3.
In an alternative embodiment, the primer layer 808 is omitted.
[0055] As shown in FIG. 8, a print layer 810 and an adhesive layer
812 are sandwiched between the primer layer 808 and the base layer
806. The print layer 810 can be applied to the underside of the
outer layer 844 (via the primer layer 808) by digital printing,
silkscreen, solvent ink, foil stamp or other printing method known
in the art. The adhesive layer 812 can be the same as adhesive
layer 312 described with reference to FIG. 3.
[0056] The following disclosure describes several specific
non-limiting examples of adhesive covers and processes for making
adhesive covers in accordance with embodiments of the present
invention.
[0057] One exemplary process 900 for manufacturing the adhesive
cover 300 is illustrated in the flowchart of FIG. 9. The process
900 starts with obtaining a desired base layer 306. In one
embodiment, the base layer 306 is obtained from a supplier with the
adhesive layer 304 and release liner 302 already adhered to the
base layer 306. At a step 902, the base layer 306 is corona
treated. Corona treatment can improve the dyne level of the base
layer 306 surfaces and consequently the adhesion of inks to the
base layer 306 surface. In other words, corona treatment can
improve "printability" (e.g. ink absorption) of the base layer 306.
Next, at step 904, the base layer 306 is coated with a primer, such
as Digiprime 5000 primer commercially available from Michelman Co.
The base layer 306 is then hot air dried at step 906. Once
sufficiently dry, a digital printer applies a desired design to the
base layer 306 at step 908. The digital printer can use a four
color process in conjunction with, for example, two additional spot
colors. Printing can also be performed via a blanket transfer. Any
suitable digital printer may be used, for example the Hewlett
Packard Indigo ws 4050 Digital Press. A print speed in the range of
1 to 150 ft/min, preferably 50 ft/min may be used. The print area
can be 12.1 inches by 17.1 inches with a web of 12 to 13 inches.
The base layer 306 can be corona treated once again at step 910 and
then cold laminated with the top layer 302 at step 912 using
in-line or off-line digital converting equipment. The lamination
step 912 may be performed by Veritcut System supplied by Rotoflex
International.
[0058] The adhesive cover 300 can then be cut to its desired shape,
which can be done by knife cut, rotary die cut or laser cut, at
step 914. An i-XE10 supplied by i-cut of Lake Geneva, Wis., may be
desirable for adhesive covers having a customized shape. The i-XE10
can access a pre-populated data file containing information
relating to the shape to which the adhesive cover is to be cut.
Alternatively, a Vericut System may be used for rotary die cutting,
slitting, sheeting, counting and stacking Rotary die cutting may be
desirable for cutting large quantities of similarly shaped adhesive
cover shapes.
[0059] The adhesive cover is packaged and shipped at step 916.
[0060] Decorative pieces 402 can also be applied to the adhesive
cover during the manufacturing process 900 or provided to a user
separately.
