Definitions

  • the present invention relates generally to packages and packaging bags for insertion into publications, processes for making such bags, and publications containing packaging bags. More particularly, the present invention relates to packaging bags for insertion into publications having multiple pages, particularly wherein, in the publication's final form, folded pages or collated pages are fastened together by means such as saddle stitching, side stitching or are perfect bound.
  • a variety of different packages for conveying printed matter and/or product samples are known in the art.
  • multiple objects such as printed items like brochures or reader service cards are enclosed together inside a skin or envelope, with the intended recipient's name and address applied to the outside.
  • One such package or envelope may be made by folding a single, elongate sheet of material around the objects to be included so that the edges of the sheet approximate each other along the sheet's length.
  • a seal is then formed between the edges by any or all of heat, pressure and/or adhesive, to obtain an elongate tube containing multiple, identical units of printed matter, product samples and/or some other object.
  • the tube is sealed and severed between each of these units so that individual packages or envelopes are obtained, with each package or envelope containing a single unit of included material.
  • the intended recipient's address may be preprinted on the inside or outside of the sheet or "wrapper", or on an insert inside the package so that the intended recipient's name and address are visible through a transparent portion of the wrapper. Alternatively, this information may be applied to the individual packages or envelopes after formation of the package or envelope is complete.
  • blown-in cards have the disadvantage of not being secured in the publication, so that they readily fall out and become separated from the publication before it reaches its intended destination. Further, blown-in inserts rely on the force applied by the publication's pages for the insert to remain in place, and hence are inherently unsuitable for conveying materials such as packages of multiple cards or product samples which may be too heavy or bulky for the publication's pages to effectively retain in position.
  • U.S. 4,509,759 discloses a game card for insertion between the pages of a folded publication, therein the game card is printed on a larger portion of a card which is dimensioned such that a smaller portion of the card extends across the fold to the pages opposite those that the game card portion is situated between.
  • Similar inserts which may be used to convey product samples by laminating the samples to the larger portion of the card, are disclosed by U.S. Patent No. 3,275,316.
  • U.S. Patent No. 4,433,783 A package for conveying soap powder samples is disclosed by U.S. Patent No. 4,433,783. This package is formed by sealing rectangular front and back panels together, with several ounces of soap powder spread in between. Additional seals are provided part of the way across the package to discourage the soap powder from shifting position substantially within the package, while permitting the passage of air from one portion of the package to another. Although this patent indicates such packages may be used as inserts for magazines or newspapers, no means of insertion into publications or means of securing such an insert within a publication is disclosed.
  • U.S. Patents Nos. 3,369,732 and 4,795,193 disclose provision of return envelopes in bound publications such as magazines or booklets. These unsealed envelopes are designed to be removed from the publication and used to send a reply through the mail.
  • a continuous series of envelopes with detachable edge strips for feeding the envelopes through high speed processing equipment such as printers is disclosed in U.S. Patent 3,608,816.
  • These envelopes may contain printed inserts e.g. useful for example in banking operations to send statements to depositors.
  • the present invention is directed to a publication comprising a plurality of pages, wherein the pages have parallel opposing top and bottom edges connected by a spinal portion which extends perpendicular to the top and bottom edges and the pages are bound together at the spinal portion by binding means.
  • This publication contains a packaging bag bound to the spinal portion, and this bag comprises at least one sealed envelope containing at least one insert therein.
  • the bag's envelope comprises overlaying front and back-all portions, each of these wall portions having opposing top and bottom edges connected by opposing spinal and side edges with at least one of the top and bottom edges having a trim segment, and the spinal edge having an adjacent or coextensive fastening area whereby the bag is bound to the spinal portion of the aforementioned plurality of bound pages.
  • the present invention is directed to a packaging bag particularly adapted for insertion into a publication which is folded in its final form.
  • This packaging bag comprises a plurality of sealed envelopes containing one or more inserts. These envelopes are attached to each other along at least one margin of the envelopes. At least two of the envelopes are separated by a fastening area such that at least one of the inserts in one of the envelopes is different from the inserts in an adjacent envelope.
  • Another embodiment of the present invention also is directed to a packaging bag which consists essentially of two sealed, insert-containing envelopes attached to each other along one margin of the envelopes and being separated from each other by a fastening area and which optionally has at least one trim segment and/or pick-up lip.
  • Another embodiment of the present invention includes a packaging bag which comprises a plurality of sealed envelopes which are attached to each other along at least one margin of said envelopes, and a fastening area.
  • the fastening area is positioned between at least two of the envelopes and includes means for making the packaging bag bend preferentially at the fastening area.
  • the portion of the packaging bag on one side of the fastening area is slightly larger or longer than the portion on the other side of the fastening area.
  • each envelope be separated by the adjacent envelope or envelopes by at least one seal, although at least two substantially parallel seals are more preferred. It is also preferred that the seal extend across the width of the envelope.
  • the optional means for making the packaging bag bend preferentially at the spinal edge or at the fastening area include a score and/or a plurality of perforations in the fastening area. This score or these perforations preferably are located between two substantially parallel seals.
  • the present invention is also directed to a process for making a packaging bag which is particularly adapted for insertion into a publication which is folded in its final form.
  • This process comprises the steps of placing insert material inside a tube; sealing said tube widthwise periodically along its length to form a plurality of compartments which are separated from each other by at least one seal; and cutting said tube widthwise periodically along its length so that said tube has two to four compartments between adjacent cuts and optionally folding the bag so that the opposing portions of the bag which extend from the fold are of uneven length to facilitate handling e.g. collation in a saddle stitch binding operation.
  • the tube is formed by the steps of wrapping a continuous web of sheet stock around a form and said insert material so that two opposite edges of said stock approximate each other and said insert material is enclosed therein; and sealing said opposite edges together to form said tube.
  • the edges may be folded in offset fashion.
  • a seamless, tubular film may be formed by known means in the first instance, thereby reducing the number of seals for each compartment from three to two.
  • the seals may be formed by the application of pressure to the tube with or without an adhesive such as glue, and more preferably by the application of both heat and pressure with or without an adhesive such as glue.
  • Either tubular or sheet stock may be employed, having monolayer or multilayer construction.
  • Suitable stock includes paper, cellophane, metal foils and thermoplastic films including those made from polyesters, homopolymers and copolymers of olefins, such as polyethylene and polypropylene, linear low density polyethylene and very low density polyethylene.
  • films made from biodegradable plastics including cellulosic and starch-derived materials may be suitably employed.
  • the stock may be single layer or multilayer stock formed by well known lamination processes or coextrusion means.
  • the stock may be coated with various agents to improve printability, sealability, or to control static electricity or other parameters.
  • the stock may also be metallized. Many such films are commercially available and All known in the art. Examples of preferred stock include paper, polyethylene, polypropylene and a laminate of metallized polyester and polyethylene.
  • the present invention additionally is directed to a publication containing a packaging bag, comprising a plurality of pages folded and collated to form a multi-page publication having a central fold, and a packaging bag which includes a plurality of sealed envelopes containing one or more inserts, the envelopes being attached to each other along at least one margin, such that at least two envelopes are separated by a fastening area.
  • the packaging bag is inserted between pages of the publication such that the fastening area overlaps the central fold, and at least two of the envelopes are on opposite sides of the fold.
  • This publication preferably is stapled periodically along the fold, with staples preferably being placed on each side of the packaging bag fastening area, and more preferably at least one staple being stapled through the fold and the fastening area.
  • the position of the packaging bag may "float" e.g. between two staples or be located anywhere from the top to the bottom of the publication, but preferably will be fastened with an edge of the bag coextensive with the top or bottom edge of the publication.
  • Publication as that term is used herein means a printed work on paper or a synthetic paper and includes magazines, newspapers, brochures, catalogs, booklets, periodicals, books and the like, all of which contain a plurality of pages.
  • a web or roll of paper may be printed on either or both sides and subsequently cut into sheets, or cut sheets may be so printed.
  • a single sheet of paper may have printing on both faces or sides to form a single leaf having two pages in a publication.
  • a single sheet may have printing on one or both faces so that the sheet may be folded in half to produce a folded sheet having two leaves and four pages.
  • a single sheet may be printed such that it may be folded multiple times to produce a publication of multiple leaves and many pages and this may be termed a signature.
  • One or more signatures may be bound along or adjacent to one fold, termed a spine, and subjected to a cutting or trimming operation to form leaves which are connected at a coextensive spinal edge or fastening area and yet which are separable at the side opposite the spine and separable as well at the top and bottom so that the leaves may be turned to view each page.
  • the leaves or pages may be bound together at the spinal portion or at an adjacent fastening area by binding means including mechanical or chemical binding means such as sewing, stapling or use of an adhesive.
  • a significant number of publications such as many newspapers, catalogs and magazines, are produced by printing at least two pages of indicia such as type, photographs and/or drawings, separated by a blank strip (gutter), on the front, back, or both front and back faces of a sheet or a web which is later cut into sheets.
  • the printed sheets contain facing pages which may then be collated with other similarly printed pages, and the sheets folded along the blank strip to create a multiple-paged publication wherein each of the above-described sheets forms two leaves.
  • the sheets are fastened together in the area of the fold, such as by staples (currently referred to in the art as "saddle stitching") or some other similar device, to make the publication more durable during distribution and reading.
  • Some publications, such as newspapers, may subsequently be folded one or more additional times to facilitate storage, mailing or other modes of distribution.
  • the "final form" of a publication is that form in which a publication ordinarily is used by a consumer.
  • a packaging bag having at least one sealed envelope containing at least one insert, which bag is adapted for binding into a publication.
  • a package comprises a sealed envelope containing at least one insert.
  • This envelope has a front wall and a back wall with connected sides. At least two sides of the envelope have a trim segment with at least one of these trim segments extending perpendicular to the other trim segment.
  • Each trim segment is of sufficient width for removal by a trimming operation without opening the envelope. This width is typically at least 1/16 inch, preferably at least 1/8 inch, and may be at least 1/4 inch.
  • trim segments will range in width from about 1/16 inch to about 1 inch with a preferred range of between about 1/8 inch to about 1/4 inch. Larger trim widths may be employed, but generally offer no material advantage and contribute to waste.
  • trim width Too small of a trim width may cause an envelope to be cut open during trimming, thereby undesirably and prematurely releasing its contents. Also, if the trimming operation is set to trim too little off the edges of the publication's pages, then the resultant trimmed publication will have a sloppy appearance with uneven page edges. Therefore the trim segments should be of sufficient width to fulfill their purpose, which is to allow collation of the package or packaging bag with a plurality of pages which will subsequently be bound and trimmed to form a publication having a neat appearance with even edges.
  • the trim segments will generally have straight edges thereby allowing the trim segment edges to be utilized to align the package or bag with at least one edge coextensive with the spinal or backbone portion of the publication and preferably also having a bag edge coextensive with either the top or bottom edges of the publication.
  • the packaging bag may be jogged to the top or bottom of a plurality of pages, or float to any position in between and then be bound in place and trimmed.
  • a package comprising a thin walled bag having a top edge and opposing bottom edge connected by opposing first and second side edges.
  • This bag has a fastening area with an optional fold (or fold line) therein which extends from the top edge to the bottom edge of the bag.
  • this bag has on each side of the fastening area at least one sealed envelope containing at least one insert, and the distance from the fold (or fold line) to the first side edge of the bag is different from the distance from the fold (or fold line) to the second side edge of said bag.
  • the difference in distance between the fold (or fold line) and the respective opposing first and second side edges is beneficially at least about 1/4 inch, probably at least about 3/8 inch and most preferably at least about 1/2 inch.
  • This difference provides an offset portion, termed a "pick-up lip", which may be used to manipulate the bag during collation with a publication.
  • the bag is folded and a plurality of bags provided to a bindery in a folded condition.
  • the bindery may easily use known equipment to handle and manipulate the folded bags in a manner similar to that used for folded pages in a bindery operation.
  • the bag is folded along a fold line which may be formed e.g. by a score and/or a series of perforations.
  • at least one of the top, bottom, and side edges of the bag will further comprise a trim segment.
  • the invention is applicable to publications having various types of binding, and various embodiments may have particular advantages for certain types of binding operations.
  • there are five operations or steps which may be utilized in the production of a bound publication viz scoring, folding, collating, stitching, and trimming.
  • Publications may be formed using some or all of the above operations.
  • a web of paper is printed on both sides, then cut into sheets with scoring occurring simultaneously with, or subsequent to, cutting.
  • a "score" as the term is used herein is defined as a crease in a web or sheet which is made to facilitate folding. Scores may be of varying widths. Folding may also be facilitated by a series of perforations. Scoring may be performed using a scoring rule which is raised from the surface of a plate or cylinder to impress or indent a crease into paper as the paper contacts the plate or cylinder.
  • the scored paper may be folded e.g. using a buckle type folding machine in which a sheet is fed into a fold-plate of adjustable length which has a stop. The sheet is forced into the stop causing the sheet to buckle about the score line and then carried between rollers which fold the sheet.
  • the folding operation may include both parallel and right angle folds.
  • Folding machines may have attachments for scoring, perforating, slitting, trimming and/or pasting. It is known to fold a sheet into a signature of as many as 64 pages. Folds may also be made without scoring or perforating.
  • the folded sheets After folding, the folded sheets (signatures) are collated to collect together in proper sequence the intended pages of the publication.
  • the collated signatures may then be bound together in a stitching operation.
  • stitching arises from an historical method of binding where the leaves or sheets of a publication were sea together. Sewn binding may be used in the present invention, however "stitching" has also come to refer to other binding means such as stapling with one or more metal staples.
  • side stitching the folded and collated pages are placed under a stitching head where at least one, and preferably at least two staples are inserted through a fastening area adjacent to the fold or spinal portion.
  • staples are typically inserted about 1/4 inch from the backbone or spinal edge and enter first through the leaves on one side of the fold and then exit through the leaves on the other side of the fold.
  • Saddle stitched publications are generally easier to open and will more easily lie open flat than side stitched publications. However, side stitching is generally used for publications too thick for suitable saddle stitching.
  • Perfect binding is an inexpensive way to bind together pages or leaves usually of a relatively thick publication. Perfect binding may be thought of as a variation in side stitching in which, after collation of the signatures or pages, the collated leaves are held together while a portion of the backbone or spinal portion is ground off to produce a rough spinal edge with evenly placed (coextensive) spinal page edges to which a flexible adhesive is applied. A cover is then glued to the spine over the bound publication.
  • suitable adhesives which maintain sufficient flexibility, resilience and strength for the expected useful life of the publication.
  • a spinal portion of a plurality of pages may extend along a backbone edge of a plurality of folded or unfolded collated sheets or pages and this spinal portion may be utilized as the fastening area to bind together the sheets or pages into a bound publication.
  • Both perfect binding and side stitch binding may be employed to bind together a plurality of unfolded sheets or leaves.
  • a trimming operation while unnecessary to open up the top, bottom and/or side edges to allow the pages to be freely turned about an axis coextensive with the bound spine, may be used to produce even coextensive page edges producing a publication with a neat appearance and smooth uniform edges.
  • Another type of suitable binding is a mechanical binding using e.g. a wire spiral or plastic coils.
  • the publication After binding, the publication is usually trimmed on the top, bottom and at the side edge opposite the bound spine.
  • the top, bottom and side edges may be trimmed serially or simultaneously using apparatus well known in the art.

Therefore, for example, cough syrup may be pre-packaged in a suitably inert package meeting all applicable governmental regulations for packaging materials in contact with a drug or comestible. Cough syrup, being a liquid (or solid in liquid suspension), will presumably require a packaging material which is either impermeable or acts as a barrier to transfer of the syrup across the packaging material and which is also non-reactive therewith.
  • This pre-packaged syrup may be inserted either alone or with a second insert such as printed patient instructions and/or cautionary information into one envelope while an adjacent envelope contains a different insert which may be totally unrelated such as fabric swatches or printed cards bearing indicia e.g. advertising household services.
  • These envelopes may be made using inexpensive materials such as paper or polypropylene without concern for odor, oxygen or moisture permeability or reactivity with the product sample (in this example cough syrup but the product sample could similarly be perfume or a food product, etc.).

  • the trim segment may include a portion of the seal as long as the seal is not totally removed or its integrity damaged to an extent thereby the contents of the envelope may fall out.
  • the sealing area is coextensive with the trim segment.
  • a trim segment which comprises a sealed together front wall portion and back wall portion may have added strength to support the bag without unintended folding during collation and any jogging or shaking operation to position the bag.
  • Packaging bag 120 has a series of perforations 132 extending from the top edge 123 to the opposing bottom 122 whereby the sealed envelope 129 is separable from the fastening area 133 by tearing along the perforations 132.
  • bag 120 may be bound into a publication by bag binding means at fastening area 133 and the sealed envelope may be separated from the publication by tearing along the perforations 132.
  • the fastening area 133 is utilized to fasten the bag 120 to a publication in the publication's spinal area.
  • Fastening area 133 extends along the spinal edge 124 and is coextensive with the spinal trim segment.
  • the width of the spinal trim segment is measured from the spinal edge toward the transverse seal 127a.
  • the trim segment should not extend past perforations 132.
  • the spinal trim segment (which extends along the spinal edge) will have a width of at least about 1/8 inch.
  • Bag 120 also has printed thereon indicia 134 on a front wall panel 135 circumscribed by seal 126, seal 127a, bottom edge 122 and perforations 132.
  • a sealing area such as seal 127a may be coextensive with the fastening area and/or a spinal trim segment.
  • the width of the seals may vary but preferably the seals will have a width between about 1/8 inch to about 1 inch. Seals having widths smaller than 1/8 inch may not have sufficient strength to maintain the insert in the envelope during normal handling. Whether or not a seal has sufficient strength will of course depend upon not only the seal width, but the type of seals, whether they are continuous or intermittent and the type, shape, and eight of the insert, as well as parameters relating to publication formation and handling. Such variables will be taken into account in forming seals and satisfactory seals of sufficient width may be determined without undue experimentation. Seals widths larger than 1 inch (2.5 cm) may be employed but generally are not necessary.
  • the envelope 129 has perforations 136 across the front wall portion 121 and back wall portion (not shown) from top edge 123 to bottom edge 122 whereby the envelope 129 is openable by tearing along the perforations 136.
  • Such perforations may extend only along a portion of the envelope 129 as long as they facilitate formation of an opening sufficient to remove the insert.
  • Envelope 129 and bag 120 may be colored, black, white, printed, opaque, translucent, and transparent.
  • bag 120 is printed upon with indicia 134, but is otherwise transparent allowing visual perception of the insert 128 contained in a sealed envelope 129.
  • Insert 128 is a prepackaged product sample of e.g. scented suntan lotion which contains its own information and indicia 137 imprinted thereon.
  • an odor barrier film may be used to prepackage the product sample as an insert 128 for subsequent packaging in bag 120 which may be made of an inexpensive material such as paper or polypropylene without concern for odor release, leakage, oxygen or moisture or gas or liquid permeability.
  • Insert 128 may be product samples which are preferably prepackaged or printed matter e.g. a plurality of printed cards.
  • a front view of a publication 140 is depicted with a cut away portion showing a packaging bag 120 having a sealed envelope 129 contained therein.
  • the packaging bag 120 of Fig. 11 is especially suited for binding into a perfect bound or side-stitched publication.
  • Publication 140 has a top page 141 which has a top edge 142, spinal edge 143, bottom edge 144, and side edge 145.
  • Top page 141 is printed with indicia 146.
  • Page 141 is collated with a plurality of pages such as middle page 147 having printed indicia 148.
  • Bag 120 is collated within publication 140 atop page 147 with the top edge 123 of bag 120 in envelope 129 having top trim segment 130 in substantial alignment with the publication's pages such as the top edge 142 of page 141.
  • the spinal trim segment 131 of bag 120 is adjacent to the spinal edge of the publication's pages such as top page spinal edge 143.
  • the collated pages and bag will normally be subjected to a trimming operation prior to binding.
  • Top page 141, bottom page 149 and middle pages such as middle page 147 have a collective spinal edge 150 and side edge 151 which are uneven.
  • a top view is presented of the collated publication 140 of Fig. 13 following a trimming and binding operation.
  • Side edge 151 and spinal edge 150 have been trimmed and are even.
  • a layer of a flexible adhesive 152 has been applied to spinal edge 150 as binding means for binding together a plurality of pages and packaging bag 120.
  • a cover sheet 153 has also been attached to the spine at the outer surface of the flexible adhesive 152 to produce a finished publication.
  • a variety of materials may be used to form the packaging bag, consistent with the invention, and many suitable materials are available from commercial sources.
  • Either tubular or sheet stock may be employed, having monolayer or multilayer contruction.
  • Stock selected from the group consisting of paper, cellophane, and thermoplastic films including those made from homopolymers and copolymers of olefins, such as polyethylene and polypropylene, linear low density polyethylene and very low density polyethylene, may be suitably employed as well as films made from polyesters and biodegradable plastics.
  • the stock may be single layer or multilayer stock formed by well known lamination processes or coextrusion means.
  • the stock may be coated with various agents to improve printability, sealability, or to control static electricity or other parameters.
  • the stock may also be metallized. Many such films are commercially available and well known in the art. Examples of preferred stock include paper, polyethylene, polypropylene and a laminate of metallized polyester and polyethylene.
