Abstract
A business form is provided which is particularly useful in shipping products where certain preprinted information can be provided and then individualized information is printed before the form is applied to a substrate. The form includes a face ply which has a pattern of adhesive applied to at least a portion of the inner face, and a release liner which includes a pattern of adhesive which exposes a portion of the release liner to direct adhesive contact to the face ply without intervening release coating to permanently adhere a part of the release liner to the face ply. The release liner has a surrounding protective border provided with release coating on the release face thereof and which is removed prior to application to the substrate, and a slip which remains with the form as applied to the substrate. The face ply includes lines of perforation defining a central portion. At least a part of the central portion is directly adhered by the adhesive to the slip without intervening release coating between the adhesive and the slip or the central portion. Individualized indicia, such as an address, may be printed on a label area of the top face of the central portion, while other individualized indicia, such as the content of a package, may be printed on the back face of the slip. Masking indicia is preferably provided on one of the inner face of the top ply or the release face of the release liner to inhibit viewing of the content indicia until the slip is removed from the package.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention broadly concerns a business form adapted for receiving variable printing of information on both sides of the form an subsequent attachment to a substrate. In one particular usage, it is more particularly concerned with a business form which may be used as a combination address label and packing list for use in shipping articles to a customer, and may include a return label portion.




2. Description of the Prior Art




The use of adhesive labels has become a growing segment of the business forms industry with the emergence of catalog sales and other home shopping vehicles. In addition to traditional wholesale shipments and delivery to commercial accounts, consumers increasingly elect to make purchases through telephone solicitations, through global computer networks, and catalogs. Shippers have thus looked for methods of increasing the efficiency of the shipping and handling process.




A variety of different labels have heretofore been developed for use in shipping products. These labels increasingly use ready to apply adhesives such as pressure sensitive adhesives, rather than adhesives which require wetting for activation, because of greater reliability of adhesion and ease of application. Such ready-to-use adhesives typically require the use of a coated liner to prevent premature adhesion, the liner being discarded as waste. However, with the increased need for security and efficiency in the shipping of packages, there has arisen a need for improved business forms which will minimize the number and size of the sheets in the form, while providing for selective adhesion to the underlying substrate and security in regard to the contents of the package, and also matches the shipping label and contents set forth on the packing list.




SUMMARY OF THE INVENTION




These needs have largely been met by the duplex carton label/packing list of the present invention. That is to say, the present invention provides a simple and economical business form which is easy to use, provides good adhesion to the underlying package or other substrate, limits waste, minimizes the number of sheets required in the form by performing multiple functions and provides good security by limiting the ability to view the packing list after application to the package. A portion of the liner sheet also functions as a packing list, thus limiting the number of plies necessary during manufacture and use. Moreover, the invention contemplates duplex printing of the liner in a single pass through a printer, so that both the addressee information and the packing list can be simultaneously printed on the form which is then ready to use. Lines of weakness and separation are provided in the face ply and release liner to permit access by the recipient to desired portions while the remainder stays affixed to the substrate. Adhesive is selectively applied in patterns between the face ply and the backing ply to provide good adhesion to the substrate without overextending into the areas serving as the packing list.




Broadly speaking, the present invention includes a face ply having a top face and an inner face and a release liner having a release face which is pattern coated with silicone release liner to provide both coated and uncoated regions, and a printable back face. Adhesive, such as a pressure-sensitive adhesive, is applied in a pattern between the plies. Preferably, the patterning of adhesive and silicone release coating provides areas between the face ply and release liner which are free of both silicone coating and adhesive, and some areas which have adhesive only to provide permanent adherence between the plies. Lines of perforation or separation are preferably provided in the face ply to define a central portion which may be further divided by perforation lines for use as an address label, return label, or pull tabs, and a surrounding border portion for adhering to the substrate, as well as a tear strip for facilitating access to the central portion. The release liner may be provided with lines of perforation or separation to permit removal of the release liner in a surrounding border for adherence to the substrate, and a remaining packing label or list portion.




In preferred embodiments, the placement of the adhesive and silicone release can be varied to provide alternate configurations for the label. For example, in a first embodiment, the central label portion can be of double thickness by providing adhesive but not silicone release between the face ply and the release liner in the central label area. This yields a document suitable for filing and a more durable label which has greater tear resistance. In a second embodiment, the label portion may be divided by lines of perforation or severance so that a double thickness end tabs are provided, but single thickness address labels and return address labels are provided separate from a printable area on the release liner. It is desirable that one of the inner face and release face be printed with ink so as to cover and visibly screen the printing appearing on the printable back face of the liner to prevent viewing after application to the package without removal from the package.




The duplex carton label/packing list is easy to use. After preprinting each of the face ply and release liner as desired, applying the silicone liner and adhesive in the desired patterns, and making the appropriate perforation lines and lines of separation through perforation wheels or die cutting, for example, the forms, which are preferably provided as continuous webs separated into individual forms by transverse perforations, are ready for local use. The user inserts the form into an ordinary printer where no stylus is required. Most preferably, duplex printers for simultaneously printing both the back face and top face are used, although the form permits sequential printing of top face and back face. Thus, computerized information can quickly be printed giving both the recipient's address on the top face and the packing list on the back face. Either continuous feed or cut sheet versions can be used. The perimeter portion of the release liner is removed and the remainder of the form is then applied to the package, with the address visible on the top face. When the package arrives at the recipient, access is gained to the packing list by placing a finger under one edge at a designated location between the tear strip perforations and pulling on the tear strip. The central portion is then pulled free through die cuts on the release liner and perforations or other lines of weakness in the face ply, exposing the rear of the central portion as a packing list while the remainder of the form is adhered to the package.




As a result, high volumes of labels and packing lists can be generated as a single form, as a single pass through a high-capacity duplex printer can generate and print the necessary information. As no carbon paper or other transfer media is employed to reprint the image on different plys, no stylus is necessary and ink-jet, laser or thermal-transfer printers may be used. The form can be preprinted with the exception of the individualized information to save time. Application of the address label and packing list to the package simply requires removal of the protective portion of the release liner, preferably located around the perimeter of the central area, and application to the package. This avoids the possibility that the packing list and address label will be separated and misapplied to different substrates. Upon receipt, the user grasps the tear strip which separates from the backing to allow the central area to be torn free and exposing the back face of the central area bearing the printing showing the contents or other information to be revealed to the recipient. The label is also tamper evident, such that the recipient can readily see tears to the form if others have sought access to the information on the back face.




The principal benefits and uses of the present invention will be readily apparent to those skilled in the art with reference to the following description and the drawings appended hereto.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawing, a composite address label and packing list form


20


particularly suited for local duplex printing is shown in FIG.


3


and includes a face ply


22


and a release liner


24


. The face ply


22


has a top face


26


and an inner face


28


oriented toward the release liner


24


, and the release liner has a release face


30


oriented toward the face ply


22


and a back face


32


. Adhesive


34


and a silicone release coating


36


are applied in patterns between the face ply


22


and the release liner


24


to permit selected attachment of the face ply to the release liner in some areas and to facilitate separation in others. Printing as well as lines of perforations or full severance by cutting are provided in certain areas of the face ply


22


and release liner


24


to provide the form


20


hereof. Advantageously, some of the printing may be accomplished during manufacture, while other printing on the forms is individualized on a form-by-form basis.




It may be appreciated that the form


20


as shown in

FIG. 3

is illustrated as a continuous web


38


of a connected series of forms


20


separated by cross-perforation lines


40


through both the face ply


22


and the release liner


24


into the individual forms


20


. This construction permits fan-folding of multiple forms and continuous feed during printing. When provided as a continuous web


38


, the forms


20


may initially include a control margin


42


along one or both longitudinal sides with feed strips


44


and


46


defined by longitudinally extending lines of weakening


48


and


50


, the feed strips


44


and


46


being provided with tractor feed holes


52


. However, the form


20


may also be provided in individual cut sheets rather than as a continuous web of connected forms, dispensing with the need for the feed strips


44


.




In greater detail, form


20


includes a top margin


54


, a bottom margin


56


, and side margins


58


and


60


. The face ply


22


includes a central portion


62


for functioning as an address label


64


and a surrounding border portion


66


positioned outboard of said central portion for attachment to a substrate such as a package as shown in FIG.


8


. As used herein, “inboard” relates directionally to the inner or central part of the form inwardly of the margins, while “outboard” refers directionally toward the area more proximate the margins. The face ply


22


may include preprinted indicia


68


including, for example, instruction indicia


70


for using the form


20


and identifying indicia


72


for identifying the sender. Spaced apart first and second tear strip perforation lines


74


and


76


are provided in the face ply


22


and extend from the top margin


54


almost to the bottom margin


56


to provide therebetween a tear strip


78


. Central portion


62


is defined within the top ply by tear strip perforation line


76


and by spaced-apart first and second transverse perforation lines


80


and


82


generally parallel to the top and bottom margins and by label perforation line


84


generally parallel to side margins


58


and


60


. Border portion


66


generally lies between the side margin


58


and tear strip


78


, and between top margin


54


, bottom margin


56


, and side margin


60


and central portion


62


.




Adhesive


34


is strategically applied in a pattern between the face ply and the release liner. Preferably, the adhesive is a pressure sensitive adhesive, and is applied in a border pattern


86


on the inner face


28


of the face ply


22


beneath the border portion


66


, but preferably recessed about


1


mm outwardly from the perforation lines


74


,


80


,


82


and


84


to resist adhesive migration and undesired attachment between the face ply


22


and the release liner


24


. The border adhesive pattern


86


is not continuous in that part of the border portion


66


on the inner face


28


which is between tear strip perforation lines


74


and


76


except for a patch


88


of adhesive shown in

FIG. 5

to facilitate access to the tear strip


78


by the user but inhibit premature separation of the face ply


22


from the release liner


24


. A second, label adhesive pattern


90


is applied to the inner face of face ply


22


spaced interiorly of the perforation lines


76


,


78


,


80


and


84


to provide an adhesive free ring


92


. A packing slip


94


is provided by a die-cut line of separation


96


in the release liner. The adhesive-free ring preferably extends from about 1 mm outwardly of perforation lines


78


,


80


and


84


to about 1 mm inside the line of separation


96


, thus not only avoiding adhesive build up on cutting members during manufacture but also aiding in separation of the label and packing slip from the remainder of the form


20


. The adhesive


34


may be applied within adhesive patterns


86


and


90


in a continuous coating or as an intermittent coating to vary the amount of adhesion desired.




Silicone release coating


36


is applied over the release face


30


of the release liner in a release pattern


98


. The release pattern


98


preferably overlies the protective border


100


of the release liner


24


and extends slightly inboard of the line of separation


96


. However, at least a part of the release face


30


interiorly within the line of separation


96


is not included in the release pattern


98


, whereby direct adhesive connection is provided between the face ply


22


and the release liner


24


without any release coating therebetween. Preferably, this release-liner free area


102


is recessed about 1 mm interiorly of the circumscribing line of separation so that release coating is provided on the protective border


100


and across the line of separation


96


. As a result, the central portion


62


providing an address label of the face ply


22


is securely and substantially permanently bonded to the packing slip


94


in a two ply construction, with the remainder of the face ply


22


and release liner


24


outboard therefrom separable because any adhesive


34


on the face ply


22


contacts the release coating


36


and does not directly contact the release liner


24


.




Preferably, the preprinted indicia


68


includes a printed masking area


104


printed on the inner face


28


, or alternatively on the release face


30


. The indicia printed on form


20


to provide the masking area


104


is most preferably provided by ink or other visible coating which minimizes the transparency and translucency of the area to which it is printed. The printed indicia in the masking area


104


may be either continuous printing, as shown, or masking indicia as shown in U.S. Pat. No. 5,376,048 (the disclosure of which is incorporated herein by reference) as masking printing


31


or masking indicia


48


, and preferably covers more than 50% of the surface area within the line of separation


96


. That is to say, the actual ink coating is applied in a pattern or continuous coverage in the masking area effectively prevents viewing through the face ply


22


to see any printing on the back face


32


of the release liner


24


.




In use, the form


20


is fed through a printer


106


as shown in

FIGS. 1 and 2

whereby individualized indicia


108


is printed on each form


20


. While the top face


26


may be printed and the form


20


removed and reversed to present the base face


32


, the form


20


is most efficiently employed using a duplex printer


106


whereby in the same pass through the printer, individualized indicia in the form of address indicia


110


may be printed on the face ply


26


while at the same time content indicia


112


may be printed on the back face


32


. Because no transfer medium is employed, ink jet printers, laser printers, thermal printers or other non-stylus printers may be employed as well as typewriters, dot matrix, daisy wheel or other stylus-type printers.




After the individualized indicia


108


is printed, the protective border


100


is peeled away from the border portion


66


of the face ply


22


of form


20


as shown in FIG.


5


. This exposes the adhesive so that the form


20


may be securely adhered to a substrate, such as a package


114


as shown in FIG.


8


.

FIG. 6

shows the form


20


as applied to the package in

FIG. 8

, and as may be seen in

FIGS. 6 and 8

, the address label


64


presenting the address indicia


110


is clearly visible, while the content indicia


112


printed on the back face


32


is obscured from view. The construction and method of application substantially ensure a match between the intended recipient and list of contents, avoiding the possibility of mixing up an address label and a packing list because from the time of printing to application, the two are not separated or separable. This inhibits the likelihood of incurring the substantial costs and onerous tasks associated with mismatched labels and packages. Access to the back face


32


is only possible by tearing the tear strip


78


along tear strip perforation lines


74


and


76


, as shown in FIG.


7


. By tearing the tear strip


78


and then pulling up the central portion


62


along the perforation lines


80


and


82


as directed by the instruction indicia


70


, the recipient gains access to the address label


64


bonded to the packing slip


94


. The two plies of the bonded central portion


62


resist tearing and aid in maintaining the packing slip intact during tearing from the border portion. The recipient then need only tear along the label perforation line


84


to remove the packing slip


94


from the package


114


, and thereby review the information on the back face


32


as shown in FIG.


9


. Tampering is evidenced by tearing of the perforations


74


,


76


,


80


,


82


, or


84


, or around the border portion


66


.




A second embodiment is shown as form


120


and is in many respects similar in construction and use to form


20


. To the extent that elements referenced above with respect to form


20


are shown or described with respect to form


120


, the reference characters are the same. The form


120


shown in

FIG. 10

is illustrated as a cut-sheet form but could also be provided as a continuous web of forms separated by cross-perforation lines and having feed strips as discussed with reference to form


20


.




Form


120


has a face ply


122


and a release liner


124


, wherein the face ply


122


has a surrounding margin


125


recessed interiorly of the perimeter


126


of the release liner


124


as shown in FIG.


10


. The provision of a recessed area


128


provides ease of separation of the protective border


100


during use of the form


120


. Additionally, the central portion


130


includes not only the address label


64


but also pull tabs


132


and


134


and a return label


136


, defined by pull tab perforation lines


138


and


140


and another release label perforation line


142


which are parallel to label perforation line


84


and extend between transverse perforation lines


80


and


82


.




Adhesive


34


is applied to the inner face


28


in an adhesive pattern


144


as shown by the shaded area in FIG.


12


. The adhesive pattern extends into the central portion but does not extend to the address label


64


, that is, the area bounded by perforation lines


80


,


82


,


140


and


142


, and preferably about a 1 to 2 mm adhesive-free area is provided between any adhesive and the perforation lines


80


,


82


,


84


,


140


,


142


and tear strip perforation lines


74


and


76


. The masking area


104


is shown as reverse printing indicia


143


, i.e. the printing within the masking area creates indicia by the absence of ink, whereby both masking of the content indicia


112


and additional preprinted instruction indicia


70




a


may be provided on the face ply


122


. The masking area


104


is shown as only extending across inner face of the address label


64


, but it may be understood that the masking area could extend to the inner face of the return label


136


, the pull tabs


132


and


134


, or indeed the border portion


66


if desired.





FIG. 13

shows the release pattern


146


of release coating


36


applied to the release face


30


of the release liner


124


, with the dotted lines showing the margin and perforation lines of the face ply


122


for purposes of comparison and to show the registry between the face ply


122


and the release liner


124


. The diagonal lines show the coverage of the release pattern


146


, which may also extend about 1 mm across the die cut line of separation


96


if desired to assist in the separation of the packing slip


94


if the pattern of adhesive


144


is slightly misaligned, or outwardly to the perimeter of the release liner. As shown in

FIG. 14

, the back face


32


of the release liner


124


is provided with individualized indicia


108


, such as the content indicia


112


shown. Form


120


permits the preprinted indicia


68


to include return address identifying indicia


72




a


and the additional preprinted instruction indicia


70




a


, as well as instruction indicia


70


and identifying indicia


72


as shown with reference to form


20


.




Form


120


is made similarly to form


20


in that the face ply


122


and release liner


124


are initially printed with the preprinted indicia


68


, adhesive is applied in the desired pattern


144


to the inner face


28


and release coating


36


is applied in the desired release pattern


146


either to the release face


30


or to the inner face


28


after the adhesive pattern


144


has been applied, and the face ply


122


is mated in registry to the release liner


124


. The continuous web


38


of the mated face ply


122


and release liner


124


is then perforated through die cutting, perforation wheels or other conventional mechanisms, and the line of separation


96


is applied to the release liner


124


to provide the packing slip


94


. As noted above, the continuous web


38


may be cross perforated or individual forms


120


provided by cutting into separate cut sheets as shown in

FIGS. 10

,


12


,


13


and


14


.

FIG. 10

shows the use of a control number indicia


148


and a bar code indicia


150


to provide additional ease of internal accounting by the sender.




Form


120


is also used similarly to form


20


. Individualized indicia


108


including address indicia


110


and content indicia


112


are respectively printed on the top face


26


and the back face


32


are printed by printer


106


at the time of use, preferably by using computerized information regarding the recipient. The protective border


100


is then peeled away so that the form


120


may be adhesively secured to a substrate, such as package


114


, with the top face


26


bearing the address label


64


with instruction indicia


70


and identifying indicia


72


as well as address indicia


110


visible, but content indicia on back face


32


hidden and masked by masking area


104


.




The recipient may grasp and pull the tear strip along tear strip perforation lines


74


and


76


. Adhesive


34


directly contacts portions of the face ply


122


and release liner


124


within the pull tabs


132


and


133


without intervention of a release coating to provide two plys and reinforcement when the central portion


130


including the packing slip


94


are torn free from the border portion


66


. However, in form


120


, adhesive pattern


144


does not extend on the inner face


28


of the face ply


122


within the address label


64


, so that the address label


64


may be separated along perforation lines


140


and


142


from the pull tabs


132


and


134


and thus also from the packing slip


94


. This enables the instruction indicia


70




a


provided by the reverse printing within the masking area


104


to be visible to the recipient, thereby providing an additional printed surface as shown in

FIG. 12

while retaining the reinforcement provided by the two-ply pull tabs


132


and


134


and the masking function inhibiting viewing of the content indicia


112


until the packing slip


94


is torn free.




Applicant has shown the form


20


as a continuous form with tractor feed strips and form


120


as a cut-sheet form. The particular manner of production is intended to illustrate examples, rather than limitations as to the size or whether multiple forms or continuous forms are attached to one another. For example, form


20


is readily useful without the tractor feed strips shown, either as a continuous form which may be fan-folded or provided on rolls, or as a cut-sheet form. As a cut sheet form, for example, form elements


20


A and


20


B may be provided on a single standard-sized 8.5 inch by 11 inch sheet without the need for feed strips


44


and


46


and separated by a cross-perforation line


20


, although the size of the sheet is not intended to be limiting. Similarly, form


120


may be provided not as a single cut-sheet form, but also as a continuous form as shown with respect to form
