Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 12/381,509, filed on 12 Mar. 2009, which is a
continuation-in-part of U.S. patent application Ser. No.
11/901,414, filed on 17 Sep. 2007. The co-pending parent
application is hereby incorporated by reference herein in its
entirety and is made a part hereof, including but not limited to
those portions which specifically appear hereinafter.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] This invention relates generally to a label assembly and,
more particularly, to a sheet of self-adhesive labels that are more
easily removed from a backing and/or a surrounding matrix, and a
corresponding method.
[0004] 2. Discussion of Related Art
[0005] Self-adhesive labels on printable sheets for printing, such
as through a mechanical printer, an electromechanical printer, a
printing press, a digital printing or imaging device, having
individual address labels are known. After printing, each label is
removed from the sheet and applied to the desired substrate, such
as an envelope for mailing. Removal of the labels by hand is
generally performed by bending back the label sheet in a vicinity
of a corner of the first label to be removed, which causes
separation of the label and the liner. U.S. Patent Application
Publication 2005/0089663 describes an attempt to make the removal
of these labels easier or more efficient for the user. There
remains a need for further improvements for label sheets to promote
efficient label removal, particularly for relatively large mailings
or projects.
SUMMARY OF THE INVENTION
[0006] A general object of the invention is to provide an improved
label assembly having a removable portion for exposing an end
portion of the labels thereon.
[0007] A more specific objective of the invention is to overcome
one or more of the problems described above.
[0008] The general object of the invention can be attained, at
least in part, through a label assembly including a face sheet, a
back sheet, and a layer of an adhesive positioned between the face
sheet and the back sheet. A separation line divides the label
assembly into at least two portions. The separation line is formed
by a first tearable line of separation extending across the back
sheet and a second tearable line of separation extending across the
face sheet. The first tearable line of separation can be offset
with respect to the second tearable line of separation, and the
separation line includes, at an end, a non-linear portion and/or an
angled portion of one of the first and second tearable lines of
separation extending at an angle to an other of the at least one of
the first and second tearable lines of separation.
[0009] The invention further comprehends a label assembly including
a back sheet and a face sheet releasably adhered to the back sheet.
The face sheet includes a label column of a plurality of labels and
a matrix bordering the label column. Each label can abut a portion
of the matrix and can be separated from the portion of the matrix,
for example by at least one die cut. A first tearable line of
separation is formed in the back sheet and runs below the labels
within the label column. A second tearable line of separation is
formed in the matrix, and the first and second tearable lines of
separation are offset from each other. In some embodiments of the
invention, at least one of the first and second tearable lines of
separation is or includes an angled portion extending at an angle
to an other of the first and second tearable lines of separation.
In other embodiments of the invention, the first tearable line of
separation and/or the second tearable line of separation includes a
non-linear end portion, such as an arcuate end portion.
[0010] The invention still further comprehends a method for using a
label assembly having a face sheet adhered to a back sheet and
including a plurality of labels disposed in a label column. The
method includes: routing the label assembly through a printer and
printing on a first portion of the label assembly; separating the
back sheet along a first tearable line of separation which extends
at least partially below the label column; separating the face
sheet along a second tearable line of separation that is offset
with respect to the first tearable line of separation and that
extends between a label assembly edge and the label column; tearing
a first portion of at least one of the first and second tearable
lines of separation at an angle away from an adjacent portion of an
other of the first and second tearable lines of separation; tearing
a second portion of the at least one of the first and second
tearable lines of separation to expose an edge portion of each of
the plurality of labels disposed in the label column; and removing
at least one of the plurality of labels from the face sheet by
pulling from the exposed edge portion.
[0011] Other objects and advantages will be apparent to those
skilled in the art from the following detailed description taken in
conjunction with the appended claims and drawings.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0017] Each of U.S. Pat. Nos. 6,837,957 and 6,860,050 and the
entire disclosure of each is incorporated into this specification
by reference to U.S. Pat. Nos. 6,837,957 and 6,860,050.
[0018] FIG. 1 illustrates a label assembly 20 (not necessarily
shown to scale), according to one embodiment of the invention.
Label assembly 20 is desirably formed of a face sheet 22 and a back
sheet (not shown in FIG. 1). The back sheet is desirably about the
same size as the face sheet 22, but may be differently sized, such
as slightly larger or smaller than the face sheet 22. The surface
of the face sheet 22 that is disposed toward a back sheet 26
includes a layer of an adhesive material. The adhesive layer can
include any adhesive material known and available to those skilled
in the art for forming pressure sensitive, or self-adhesive labels.
The back sheet 26 is desirably formed of a material to which the
adhesive coating adheres less than or significantly less than to
the face sheet 22, such as is known for forming pressure sensitive,
or self-adhesive, labels. The adhesive coating covered by the back
sheet 26 is applied to the face sheet 22 in any suitable manner
known to those skilled in the art.
[0019] The sheet assembly 20 is of any suitable shape, and
generally any suitable size that can be accepted by and fed through
a printer, such as a laser printer or an ink jet printer. Common
sizes of paper generally fed through printers are 8.5 inches by 5.5
inches, 8.5 inches by 11 inches, 8.263 inches by 11.688 inches (A4
size), and 8.5 inches by 14 inches. The face sheet 22 is
preferably, but not necessarily, constructed of any suitable paper,
paper composite, non-metal and/or metal material that can be used
as a label. Other suitable materials for constructing the face
sheet 22 include, for example, fabric, plastic, and/or metal
foils.
[0020] The face sheet 22 desirably has a printable surface on a
side opposite the adhesive coating. In some embodiments of the
invention, the back sheet 26 has a printable surface, such as on a
side opposite the adhesive coating. The phrase "printable surface"
relates to a surface of any type of matter upon which a person or
machine can draw, print, color, paint, photocopy, write, emboss, or
make any other type of mark and/or graphic. Laser printers, ink jet
printers, impact printers, thermal transfer printers, direct
thermal printers, typewriters, or any other suitable graphic
printing devices are preferred but not necessary for use with
printable surfaces according to the invention.
[0021] The face sheet 22 and the printable surface can be any of a
variety of face materials used to make pressure sensitive labels,
or self-adhesive labels. Such face materials may include, but are
not limited to: smudgeproof stock, litho stock, cast coated stock,
tag stock, fluorescent stock, foils, computer printable polyester,
vinyl, satin cloth, Tyvek.TM. material, flexible plastic, book
papers, photo quality papers and/or photo quality film.
Furthermore, various portions of the face materials can be
different colors, thereby resulting in different colored parts.
[0022] As shown in FIG. 1, label assembly 20 can be separated along
separation lines 30 to divide label assembly 20 into portions 80,
82, and 84, such as shown in FIG. 3. As also shown in FIGS. 1 and
4, three separation lines 30 are used to divide label assembly 20,
but the label assembly 20 will be described below with reference to
only one of the separation lines 30. It is apparent that any other
suitable number of separation lines 30 can be used to divide label
assembly 20 into any suitable number of equal or unequal portions.
The separation line 30 can be formed by a first tearable line of
separation 36 extending across the back sheet 26 and one or more
second tearable line of separation 38 extending across the face
sheet 22. The first and second tearable lines of separation 36 and
38 are offset from each other, for example by less than about 1
cm.
[0023] As used throughout this specification and in the claims, the
phrase "tearable line," the phrase "line of separation," and/or the
phrase "tearable line of separation" is intended to relate to a
line of weakening of the structure of the face sheet 22 and/or the
back sheet 26. The line of weakening has a weakened structural area
along which the face sheet 22 and/or the back sheet 26 can be
separated. Each tearable line or line of weakening, according to
the invention, comprises at least one of a die cut line, a kiss cut
line which is a die cut line that does not extend completely
through a layer or a sheet, a laser die cut line, a score cut line,
a perforation line which is also known as a line of cuts and ties,
a microperforation line, a chemically etched line, a liquid etched
line and/or a gas etched line. Tearable line 36 and/or tearable
line 38 of the invention may comprise any other suitable separation
line or line of weakening known to those skilled in the art of
label assemblies.
[0024] The face sheet 22 in FIG. 1 and FIG. 4 includes three label
columns 40, each including a plurality of labels 42. The labels 42
are shown as rectangular labels, but can be of any of various
shapes such as square or circular. Also, the shape, dimensions
and/or configuration of the label columns 40 can vary depending on
need and the shape of the labels. For example, the label columns
can run vertically as shown, horizontally and/or diagonally. The
number of labels per label column or area depends on the size and
shape of the labels.
[0025] A matrix 44 can border each of the label columns 40. Each
label 42 can abut a portion of the matrix 44 and can be separated
from the matrix 44 and an adjacent label 42 by a tearable line of
separation 46. The first tearable line of separation 36 formed in
the back sheet 26 runs or extends below the labels 42 within the
label column 40. In one embodiment, such as shown in FIG. 3, the
second tearable line of separation 38 includes a portion that is
disposed along, and forms in part, the labels 42, and extends in a
direction generally parallel to a portion of the first tearable
line of separation 36.
[0026] As used throughout this specification and in the claims, the
term "first" and the term "second" and/or other similar terms are
intended to be interchangeable with each other in situations where
role reversals of elements and/or method or process steps are
possible.
[0027] In some embodiments of the invention, such as shown in FIGS.
1-3, the first tearable line of separation 36 includes an angled
portion 50 that extends at an angle to, and toward, the second
tearable line of separation 38. In other embodiments of the
invention, such as shown in FIGS. 4 and 5, the first tearable line
of separation 36 includes a non-linear section 51 positioned near
edge 58 and/or near edge 60 of the label assembly 20. The angled
portion 50 and/or the non-linear section 51 desirably helps hold
the sheet portions together during printing. At an opposite end of
the separation line 30 from the angled portion 50 or the non-linear
section 51, the second tearable line of separation 38 includes an
angled portion 52 or non-linear section 53 that extends at an angle
or arcuately to, and toward, the first tearable line of separation
36. The angled portions 50 and 52 or the non-linear sections 51 and
53 extend in the matrix 44 or the back sheet 26, respectively
between the label column 40 and an edge 58 and an edge 60,
respectively, of the label assembly 20. As will be appreciated by
those skilled in the art following the teachings herein provided,
various and alternative configurations are available for the
separation line 30 of the invention. For example, the two angled
portions 50 and 52 or the two non-linear sections 51 and 53 could
both be in the face sheet 22 or the back sheet 26, or only one end
of the separation line can include an angled portion or a
non-linear section. Also, various angles are available for the
angled end portions or the non-linear sections of the
invention.
[0028] In one particularly preferred embodiment of the invention,
referring to FIG. 1, the first tearable line of separation 36 is
formed of a perforated line of weakness having a plurality of cuts
and ties and the second tearable line of separation 38 is formed by
a die cut or a kiss cut through the face sheet 22. Desirably, the
portion of the first tearable line of separation 36 along the label
column 40 includes the cuts and ties, and the angled portion 50 or
the non-linear section 51 is formed of only a cut, e.g., a die cut,
with no tie within the angled portion 50 or the non-linear section
51. In other embodiments of the invention, the first tearable line
of separation 36 is formed of only a die cut and/or a kiss cut. In
some embodiments of the invention, the angled portions 50 and 52 or
the non-linear sections 51 and 53 stop short of the respective edge
58 and/or 60 of the label assembly 20, leaving a breakable material
bridge, similar to a tie, at the edge 58 and/or 60 in order to
provide additional strength and support during running through a
printer. In some embodiments, at the edges 58 and 60 of the label
assembly 20, the first tearable line of separation 36 is separated
from the second tearable line of separation 38 by a distance of
about 0.04 inch to about 0.08 inch, but can be any other suitable
distance.
[0029] The first line of separation 36 can include at least a
portion running generally parallel to the longitudinal direction of
the label column 40, and disposed about 0.4 to about 1.0
centimeters, and desirably about 0.6 centimeters, from one
longitudinal edge of the label column 40. The exact distance is not
critical, but desirably the first tearable line of separation 36 is
offset from that edge of the label column 40 far enough so that
when the strip 70 is removed, the labels 42, as shown in FIG. 2,
can be easily grasped and removed by the user. At the same time,
the first line of separation 36 is close enough to a corresponding
edge of the label column 40 such that when the strip 70 is removed,
a narrow enough edge portion 72 of the labels 42 with the adhesive
28 is exposed so that when the label assembly 20 is placed onto a
surface, the exposed edge of the unremoved labels 42 do not easily
and inadvertently stick to the surface.
[0030] FIGS. 2 and 3 illustrate an operation of the separation
lines 30 of the label assembly 20. FIG. 2 shows the label assembly
20 from the back, showing the back sheet 26. In FIG. 2, the user
has grasped one corner of label assembly 20 at approximately
position 74 as shown in FIG. 1 with one thumb and forefinger, and
with the other thumb and forefinger grasped the narrow strip 70 of
release liner and matrix so as to focus the shear forces along the
separation line 30, and has began tearing strip 70 away from the
rest of the assembly 20. Alternatively, for example, one portion of
the label assembly 20 can be held against a surface while another
portion is lifted away from the surface to separate the label
assembly 20. As shown in FIGS. 1 and 3, the front sheet 22 can
include printed arrows and instructions and/or other graphics for
indicating where to place the fingers during tearing.
[0031] The strip 70 tears away as the back sheet 26 is separated
along the first tearable line of separation 36 and the face sheet
22 separates along the second tearable line of separation 38. After
the strip 70 is completely removed by the user, the previously
adjacent label column 40 is left or remains with the labels 42
mostly attached to the back sheet 26 but having a relatively narrow
edge portion 72 of the labels 42 with the underlying back sheet
portion removed. The user can then easily peel off the individual
labels 42 by hand, one-by-one or otherwise as desired, without
having to bend and manipulate the label assembly 20 each time the
user wishes to remove the next label 42.
[0032] FIG. 3 shows the label assembly 20 having a full label
column 40 removed therefrom. As discussed above, the label assembly
20 includes three vertical separation lines 30, with one separation
line 30 associated with each label column 40. The separation lines
30 divide the label assembly 20 into three individual label
portions 80, 82, and 84, which may be individually separated from
each other. In FIG. 3, the left hand portion 80 has been separated
from the still combined or assembled center portion 82 and the
right hand portion 84. The labels within the left hand portion 80
are now ready to be easily peeled one by one from the back sheet 26
and applied to envelopes or other substrates or surfaces. Portions
82 and 84 do not have any portions of the labels 42 with their
adhesive sides exposed. Thus, the portions 82 and 84 can be handled
and/or stored for later use without any degradation of the adhesive
on the backs of those labels. Remaining portions 82 and 84 could
even be fed through a printer for later printing. For example, if
only ten or fewer labels are needed to be printed and used, the
user could run label assembly 20 through a printer and print only
on labels within the label column in the portion 80. The user would
then separate the portion 80 and use the labels within that
portion. Remaining combined portions 82 and 84 could be stored for
later use. When additional labels are ready to be printed, the
label assembly 20 could be fed through the printer.
[0033] FIG. 4 shows another embodiment of the label assembly 20,
according to the invention. As shown in FIG. 4, the second tearable
line of separation 38 includes or comprises the non-linear section
51 positioned near the edge 60 of the label assembly 20. Also as
shown in FIG. 4 by the dashed lines, the first tearable line of
separation 36 includes or comprises the non-linear section 51
positioned near the edge 58 of the label assembly 20. As shown in
FIG. 4, the edge 58 is opposite the edge 60 on the label assembly
20. However, any other suitable relationship can exist between the
edge 58 and the edge 60.
[0034] In some embodiments of the invention, the non-linear section
51 and/or the non-linear section 53 each has an arcuate shape. In
some embodiments of the invention, the arcuate shape can have a
radius of curvature, for example in a range from about 0.01 feet to
about 5.0 feet, or any other suitable distance or measurement.
[0035] As shown in FIG. 4, the non-linear section 51 arcs in a
direction toward the edge 58. In some embodiments of the invention,
the non-linear section 53 arcs in a direction toward the edge 60.
As shown in FIG. 4, a first direction that the non-linear section
51 arcs is generally opposite a second direction that the
non-linear section 53 arcs. In some embodiments of the invention,
the non-linear section 51 has a shape similar to the non-linear
section 53.
[0036] As shown in FIG. 4, the edge 60 is at or near a top of the
label assembly 20, and the edge 58 is at or near the bottom of the
label assembly 20.
[0037] As shown in FIG. 4, the first tearable line of separation 36
does not intersect with or avoids intersection with the second
tearable line of separation 38.
[0038] As shown in FIG. 5, the first tearable line of separation 36
intersects the edge 58 of the label assembly 20 at a distance 55
from an intersection of the second tearable line 38 and the edge
58. The distance 55 can be used to better separate the portions 80,
82 and 84 from each other. The arcuate or curved shape of
non-linear section 51 and/or non-linear section 53 can be used to
reduce the forces necessary for separating the portions 80, 82
and/or 84 with respect to each other.
[0039] Thus, the invention provides an improved label assembly
structure for promoting easy removal of labels from the label
assembly.
[0040] The invention illustratively disclosed herein suitably may
be practiced in the absence of any element, part, step, component,
or ingredient which is not specifically disclosed herein.
[0041] While in the foregoing detailed description this invention
has been described in relation to certain preferred embodiments
thereof, and many details have been set forth for purposes of
illustration, it will be apparent to those skilled in the art that
the invention is susceptible to additional embodiments and that
certain of the details described herein can be varied considerably
without departing from the basic principles of the invention.
