Description

FIELD OF THE INVENTION

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 surrounding matrix.

BACKGROUND OF THE INVENTION

Self-adhesive labels on printable sheets for printing, such as through a computer printer, of individual address labels are well 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.

SUMMARY OF THE INVENTION

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.

A more specific objective of the invention is to overcome one or more of the problems described above.

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 is offset with respect to the second tearable line of separation, and the separation line includes at an end 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.

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 of the plurality of labels abuts a portion of the matrix and is separated from the portion of the matrix 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. 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.

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.

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

FIG. 1 illustrates a label assembly 20 (not necessarily shown to scale), according to one embodiment of this 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 slightly larger or smaller than the face sheet 22. The surface of the face sheet 22 that is disposed toward the back sheet 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 is desirably formed of a material to which the adhesive coating adheres 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 is applied to the face sheet 22 in any suitable manner known to those skilled in the art.

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 sheet 22 include fabric, plastic, and metal foils.

The face sheet 22 desirably has a printable surface 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 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 this invention.

The face sheet 22 and the printable surface can be any of a variety of face materials used to make pressure sensitive, 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™ 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.

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 shown in FIG. 3. As also shown in FIG. 1, 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 is formed by a first tearable line of separation 36 extending across the back sheet 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, such as by less than about 1 cm.

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 face sheet 22 and/or back sheet. The line of weakening has a weakened structural area along which face sheet 22 and/or back sheet can be separated. Each tearable line or line of weakening, according to this 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 sheet), a laser die cut line, a score cut line, a perforation line, 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 this invention may comprise any other suitable separation line or line of weakening known to those skilled in the art of label assemblies.

The face sheet 22 in FIG. 1 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 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 or horizontally, and the number of labels per label column depends on the size and shape of the labels.

A matrix 44 borders each of the label columns 40. Each label 42 abuts a portion of the matrix 44 and is 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 runs or extends below the labels 42 within the label column 40. In one embodiment, 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.

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. The angled portion 50 desirably helps hold the sheet portions together during printing. At an opposite end of the separation line 30 from the angled portion 50, the second tearable line of separation 38 includes an angled portion 52 that extends at an angle to, and toward, the first tearable line of separation 36. The angled portions 50 and 52 extend in the matrix 44 or back sheet, respectively between the label column 40 and an edge 58 and 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 this invention. For example, the two angled portions 50 and 52 could both in the face sheet or back sheet, or only one end of the separation line can include an angled portion. Also, various angles are available for the angled end portions of this invention.

In one particularly preferred embodiment of this 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 20. 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 is formed of only a cut, e.g., a die cut, with no tie within the angled portion 50. In one embodiment of this invention, the angled portions 50 and 52 stop short of the respective edge 58 and 60 of the label assembly, leaving a breakable material bridge (similar to a tie) at the edge 58 and 60 in order to provide additional strength and support during running through a printer. In one embodiment, 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.

The first line of separation 36 includes at least a portion running 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 strip 70 is removed, 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 that 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 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.

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 back sheet 26. In FIG. 2, the user has grasped one corner of label assembly 20 at approximately position 74 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 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 for where to place the fingers during tearing.

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 with 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 as desired without having to bend and manipulate the assembly 10 each time the user wishes to remove the next label.

FIG. 3 shows 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 center portion 82 and right hand portion 84. The labels within left hand portion 80 are now ready to be easily peeled one by one from the back sheet and applied to envelopes or other substrates. Portions 82 and 84 do not have any portions of the labels 42 with their adhesive sides exposed. Thus, 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 portion 80. The user would then separate 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.

Thus, the invention provides an improved label assembly structure for promoting easy removal of labels from the label assembly.

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.

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.
