Int. Cl. B65d 27/10, 27/16 U.S. Cl. 229-69 17 Claims ABSTRACT OF THE DISCLOSURE A strip of separably connected similar fiat sheets of material suitable for forming a mailing piece when folded to form overlying panels connected adhesively at the free edges thereof, each of said fiat sheets having a mounting strip separably connected along one edge and arranged to be attached by a stripe of adhesive to suitable supporting means such as a sheet or web comprising a printed prod uct or the like, each fiat sheet when disconnected from its mounting strip being foldable upon itself and preferably having a fold line, such as a crease or other equivalent means, extending between opposite side edges intermediately of the opposite ends thereof to define a pair of panels foldable along said fold line into said overlying relationship, one of said panels also having a closing flap foldably connected to it by another suitable fold line and suitable sealing means such as a stripe of adhesive on said flap to effect final sealing of the mailing piece, narrow covering strips of sheet material which may also be provided so as to lightly adhere to said stripes of adhesive on said panels, especially when of the pressure-sensitive type to protect the same until ready to be folded into an enclosing type mailing piece, and removal tabs being provided on one end of each covering strip, if desired, to facilitate removal of said strips.

CROSS-REFERENCE TO RELATED APPLICATIONS The strip of separably connected fiat sheet mailing pieces comprising the present invention are adapted to be fed by, separated from each other, and applied to a moving printed web or the like by a machine such as the type comprising the subject matter of pending patent application Ser. No. 685,122, filed Nov. 22, 1967.

BACKGROUND OF THE INVENTION Modern advertising media are progressively making rapid expansion in the use of return-type mailing pieces of. various types. Many of these types comprise simply a return postcard comprising a single sheet of material upon which the reader applies his name and address and mails the same to an advertiser, usually by postage-paid business reply mail means. By means of such returned mailing pieces, advertisers assemble mailing lists of prospective purchasers to whom they mail advertising brochures and the like. Much of this type of advertising previously has been done on a direct mail basis.

With the advent and popularity in recent years of magazine sections inserted in daily and Sunday papers, frequently referred to as Sunday supplements and the like, extensive use of advertising is employed in said supplements with the result that quite recently, mechanism have been devised for delivering what is known as inserts and outserts, comprising single sheet advertising reply cards to precise locations on printed webs which, when folded, form said supplements.

Such advertising reply cards are fixed b adhesive at said predetermined locations upon said printed webs. While this form of reply to printed advertisements in said periodicals and publications is useful and desirable, more recent advances in advertising have found it convenient to provide means by which response by readers to ads in the periodical or supplement might be of such form that payment for articles advertised might be enclosed and remitted to the advertiser prior to sending the advertised item to the recipient. It has been found that this is a more satisfactory way of conducting business than by mailing merchandise either on a c.o.d. basis or on a conventional order basis wherein payment is remitted following receipt of the merchandise.

Certain types of envelopes constructed so as to be attached to catalog pages and the like have been devised eretofore, but, in general, said envelopes usually have :een formed from a pair of laminated sheets of paper or -he like or other equally bulky or complex arrangements. Such envelopes which comprises a double thickness of paper, when affixed to a printed web and folded into publications, unduly increase the thickness thereof and also increase the possibility of tearing, jamming and other malfunctioning of the folding mechanism occurring relative to the printed web.

SUMMARY OF THE INVENTION It is the principal object of the present invention to provide a flat sheet of readily foldable material suitable for forming a mailing piece comprising at least a pair of panels of said material which may be folded along a weakening line or the like across said piece into overlying relationship and one of said panels, if desired, also having a closing flap foldably connected thereto. Stripes of adhesive extend along the same surface of said sheet respectively adjacent the edges thereof on at least one of said panels and a mounting strip by which the sheet is secured to a supporting piece is secured detachably along one edge of said sheet.

When said stripes of adhesive are of the tacky pressuresensitive type and the piece is in flat, unfolded condition, said stripes are preferably covered by narrow strips of protective sheet material which lightly adhere thereto, and means to aid removal of the strips preferably are provided on one end of each covering strip. One form of means to aid removal thereof comprises a tab which is manually engageable to quickly and effectively remove the covering strips from the stripes of adhesive to expose the adhesive and thereby render the same available to effect sealing of at least the ends of said folded sheet into an enclosing type mailing piece which may be completely closed and sealed either by folding a closing flap onto the panel opposite that to which it is foldably connected or by other sealing means described hereinafter.

It is another object of the invention to arrange a detachably connected series of said flat sheets into a strip of indefinite length and capable of being arranged in compact manner for use in which said sheets are disposed in closely overlying relationship, either in fan-folded manner or in rolled condition for delivery to a machine capable of separating said sheets successively from said strip thereof for attachment to suitable carrying means such as a printed web of a publication or the like, said sheets being readily detachable from said strip by means of similar transverse rows of weakening means such as perforations or the like.

It is a further object of the invention to provide said aforementioned removal tabs in the form of corners respectively disposed at one end of each flat sheet and adjacent opposite side edges thereof, said corners preferably being of similar geometric configurations of any appropriate shape, such as triangular, and the like, the same being affixed to said covering strip and at least partially severed from said panel of said sheet to facilitate the quick and accurate detachment thereof from said sheet incident to removing the covering strips from said stripes of adhesive.

Still another object of the invention is to provide said mounting strip along one side edge of each fiat sheet which is separably connected thereto by a row of perforations or the like, and said mounting strip being attachable to a supporting or carrying piece such as a printed web of a publication or the like, by a stripe of adhesive either pre-applied or applied in tacky condition at the time the pieces are fed from a connected strip thereof by a suitable mechanism.

A still further object of the invention is to provide a row of separating means such as perforations along one or both side edges of said flat sheet mailing piece closely adjacent but inward from said stripes of adhesive along opposite edges thereof, whereby the completely closed mailing piece formed from said fiat sheet, when folded and sealed, may have one or both ends or even a third edge strip thereof readily removed therefrom by the addressee to expose the contents thereof.

Details of the foregoing objects and of the invention, as well as other objects thereof, are set forth in the following specification and illustrated in the accompanying drawings comprising a part of the same.

FIG. 23 is another embodiment of compact arrangement of a strip of such connected fiat sheet mailing pieces arranged in roll or coiled form from which the individual flat sheets may successively be removed for attachment to a carrying piece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention primarily is concerned with the production of an individual mailing piece formed from a single sheet of suitable material, such as any of a number of different types of paper products. In general, it is desirable that the material at least be capable of a sheet thereof readily being folded into two or more overlapping panels or flaps and then readily being sealed in such configuration so as to comprise what generally might be referred to as a mailing envelope.

Inasmuch as mailing pieces of this type are adapted to be employed in many fields of advertising, as well as order soliciting and for making payments therefor, it should be apparent that the principles of the invention should be capable of lending themselves to being incorporated in a number of different embodiments of structural arrangements. Such arrangements, however, in general, include similar basic characteristics whereby, even though a rather substantial number of different specifically illustrated constructions are shown in the drawings, there nevertheless is a substantially basic inventive theme employed commonly in each of them.

One of the relatively simple embodiments of the invention is illustrated in FIGS. 1 and 2 and comprises a mailing piece 10 formed from a sheet of suitable material of the type generally referred to above and particularly a paper product, although it is conceivable that certain forms of plastic, cloth or metal foil are suitable under certain circumstances for such purposes.

In accordance with the general preferred overall principles of the invention, a number of the individual mailing pieces 10, which are all of uniform size and structural detail, are connected in end-to-end relationship along severable lines 12 shown at opposite ends of the piece and extending between the opposite side edges thereof. Such lines 12, for example, may comprise lines of perforations, rouletting, or the like. Preferably, such severable connecting means as are used along the lines 12 should be of the type that can be severed quickly and cleanly by a bursting or jerking action which may be imposed upon the leading end of a strip of such connected pieces 10 by an appropriate machine such as of the type illustrated in the aforementioned co-pending application Ser. No. 685,122.

Extending along one side edge of the piece 10 is a mounting or attaching strip 14 which is connected to, but readily separable from, the piece 10 by a weakened means such as a longitudinally extending row of perforations 16 or the like. For purposes of attaching the piece 18 and its strip 14 to appropriate carrying or supporting means, such as a page of a magazine, newspaper supplement, or the like, a longitudinal stripe of mounting adhesive 18 is applied to one surface of the strip 14, between the outer edge thereof and the row of perforations 16. Said stripe of mounting adhesive very conveniently might be applied incident to a connected strip of a plurality of the pieces 10 being fed to a printing web or the like for attachment to predetermined locations thereon by a machine of the type shown and described in said aforementioned copending application.

The stripe of adhesive 18, for example, may comprise a so-called hot melt type of adhesive which remains fluid and tacky for a short interval of time after being melted and applied to the strip 14, for example, by said afore mentioned machine. The tacky properties of the adhesive are readily capable of remaining in adhering condition while the piece 10 is being fed to a printed sheet or other form of carrying piece and then rapidly hardens in a manner to firmly secure the attaching strip 14 and the mailing piece connected thereto to such supporting piece or web.

The strip 14 also serves an important additional function by being provided with feeding means by which a continuous strip of connected pieces 10 is positively fed at a predetermined rate of speed, for example, such as by a machine of the type shown and described in said aforementioned pending application. To accomplish this, a row of feeding perforations 20 which are punched holes, of appropriate uniform spacing and diameter, are provided continuously along the strip 14 such as shown in exemplary manner in FIG. 1. Such perforations may be engaged by the pins of a pin-type feed wheel on said aforementioned machine and thereby assure such positive feeding movement.

One very common type of use which may be made of the mailing piece 10 is to form an envelope therefrom for many purposes, among the more important of which will be the writing or typing an order upon one or both of the panels 22 and 24 which preferably are at least of the same width and are connected for folding along a suitable fold line 26. As will be described hereinafter in greater detail, the fold line 26 may be actually indicated and the folding function facilitated by making said line in the form of a crease or a series of suitably spaced perforations. This is not essential, however, because other forms of indicating and facilitating means may be employed. After the necessary data and information has been applied to one of said panels as indicated, the same are then folded upon each other, along the fold line 26, for example, and thereby form a pair of overlying panels.

To facilitate the sealing of the overlying ends of said panels into a suitable enclosing type envelope or the like, stripes of sealing adhesive 28 and 30 are applied suitably along the opposite side edges of the piece 10. As will be described hereinafter in regard to additional embodiments, it actually is only essential that the stripes 28 and 30 extend along the opposite side edges of a single panel, depending upon the type of adhesive employed. By way of one suitable embodiment, such sealing adhesive may comprise a moistenable type such as may be licked with saliva, or a wetting roller of appropriate type may be employed. Assuming that such moistenable type of adhesive is used, then it is only necessary that the stripes 28 and 38 extend substantially continuously along the opposite side edges of only one of the panels 22 or 24. An arrangement of this type generally is illustrated in FIGS. 13 and 14 and is described in detail hereinafter, like stripes 124.

In the event the cement employed for the sealing stripes 28 and 30 is of the contact type, such as a dry pressuresensitive adhesive, it is then preferred that the stripes 28 and 30 continue preferably entirely along the opposite side edges of the piece 10 so that when the panels 22 and 24 are folded upon each other, the engagement of said stripes of contact adhesive upon each other will immediately and permanently seal the same. Further, however, if a tacky pressure-sensitive type of cement is employed for the sealing stripes 28 and 30, then protective covering strips of suitable material, of the type described hereinafter especially in regard to the embodiment of FIG. 4 or the various figures on sheets 3 and 4 of the drawings, should be utilized.

In the preferred construction of the embodiment shown in FIGS. 1 and '2, it is preferred that the panel 24 be a little longer than the panel 22 in order to provide a foldable sealing flap 32 connected to the outer edge of panel 24 by a fold line 34 which may be of a nature similar to the fold line 26 as described in detail hereinabove. Further, it is preferred that a stripe of sealing adhesive 36, or a spaced series of dots thereof or the like, be provided to extend longitudinally along the sealing flap 32. Accordingly, after the panel 22 has been folded onto panel 24 and the sealing stripes of adhesive 28 and 30 have been activated or otherwise adhered to each other so as to seal the opposite ends of the folded and overlying panels, the sealing flap 32 then is folded over against the adjacent edge of the uppermost panel 22 and the stripe of adhesive is placed in sealing engagement with said surface of panel 22 so as to complete the sealing of the mailing piece 10 into a folded arrangement which actually comprises an envelope.

Appropriate enclosures such as a check, money order or other form of payment, samples of paper, swatches of cloth or the like, or other items, may be enclosed and sealed within the envelope thus formed. Under most circumstances, such a mailing piece, especially when used in connection with an advertisement on the page of a magazine or insert for newspaper, will have the address of the advertiser or order solicitor printed directly on the outer face of one of said panels and, as is customary at present, an additional indication of postage being paid by the receiver usually is applied to said panel.

Referring to FIG. 2, an end elevation of the mailing piece 10 shown in FIG. 1 is illustrated somewhat in exaggerated form to accord a concept of the relative surfaces to which the various stripes of adhesive 28, 30 and 36, as well as stripe 18 of mounting adhesive are affixed. It will be seen from FIG. 2 that all of said stripes of adhesive preferably are affixed to the same surface of the unfolded piece 10. However, under some circumstances, it may be preferred to affix the stripe of mounting adhesive to the opposite surface of the piece 10 from that surface to which the other stripes of sealing adhesive are afiixed. Such exemplary arrangement is shown in FIG. 3, for example, where the stripe of mounting adhesive 18' is shown applied to the opposite surface of the attaching strip 14 from the surface to which the stripe 18 is shown to be affixed in FIG. 2.

In the embodiment shown in FIG. 4, the general basic arrangement of the piece 10 is similar to that shown in regard to the piece 10 illustrated in FIGS. 1 and 2. Accordingly, the same reference numerals are applied to similar elements and features of the piece 10 shown in FIG. 4. The principal difference of the embodiment shown in FIG. 4 over that shown in the preceding figures lies in the use of pressure-sensitive sealing adhesive for the sealing strips 28 and 30 thereof, thereby necessitating the use of preferably continuous strips of protective material 38 and 40. These lightly adhere to and are readily separable from the strips of pressure-sensitive sealing adhesive 28 and 30. Suitable treated paper as, for example, silicon fiuid-treated paper, and the like is highly suitable for foaming the protective strips 38 and 40. To remove the same, it is only necessary to lightly loosen one end of each strip by use of a fingernail, knife blade or the like, and then quickly peel the entire protective strip from the stripe of adhesive.

A simple and convenient expedient for facilitating the gripping of the protective strips 38 and 40 is illustrated in a slightly modified form in FIG. 6 which is a fragmentary illustration of the right-hand edge of the piece 10 shown in FIG. 4 and wherein it will be seen that the protective strip of material 38' is substantially wider at least at one edge than the stripe of pressure-sensitive adhesive 28 which it protects. Such protecting edge of the strip 38' readily may be engaged by simply projecting a fingernail or the like under it and then grasping it between a thumb and finger to quickly peel the entire strip from the stripe of adhesive.

In view of the fact that when a series of connected but readily separable pieces 10 are arranged in a continuous strip form for compact arrangement for feeding to a machine of the type, for example, illustrated and described in said aforementioned copending application, the preferred method of separating the leading piece 10 from the next adjacent piece is by a bursting or quick jerk of the same to separate it along the severable line 12. Hence, the application of the protective strips 38 and 40 over the strips of sealing adhesive 28 and 30 conceivably could impede the clean and substantially instantaneous separation of said leading piece 10 from the next adjacent piece.

To obviate the possibility of any such aforementioned impedance occurring, however, it is contemplated by the present invention that, for example, as the protective strips 38 and 40 are applied to the connected strip or series of pieces 10, and incident to the scoring of the strip transversely at equal intervals to form the severable lines 12, the strips 38 and 40 may be either completely or nearly completely severed in coincidence with the severable lines 12 as illustrated in several embodiments respectively illustrated fragmentarily in FIGS. 7 and 8.

In the embodiment shown in FIG. 7, a pair of notches 42 are formed so as to extend inward toward each other from opposite side edges of the exemplary strip 38 and must also extend through the panels of sheet 10. In the embodiment shown in FIG. 8, only a single notch 44 is formed substantially in coincidence with the severable line 12 and the depth of the notch preferably is such so that it extends approximately entirely across the width of the exemplary protective strip 38. A still further embodiment comprises a clean incision transversely through the protective strips 38 and 40, substantially in exact coincidence with the severable lines 12 between adjacent mailing pieces 10. This may be done by an appropriate knife or narrow punch and thereby form a square-cut end 46 as shown, for example, in FIG. 4 which completely severs the strips 38 and 40, or they may be severed by a punched out space.

A still further, relatively simple and advantageous expedient of the invention is illustrated in perspective manner in FIG. 9. In this figure, the mailing piece 48 comprises a pair of panels 50 and 52 which are of similar length but uneven width. A mounting strip 54 which has feeding means such as a row of perforations 56 therealong is secured detachably along one edge of the mailing piece 48 by a row of perforations 58. Also, as in the preceding embodiments, a stripe 60 of mounting adhesive is applied to one surface or the other of the mounting strip 54 so as to extend longitudinally therealong for attachment of the strip and the piece 48 secured thereto to a suitable mounting or supporting piece or web as described above in regard to the preceding embodiments.

It will be seen from FIG. 9 that a fold line 62 is arranged between the panels 50 and 52, said fold line extending perpendicularly to the row of perforations 58, for example, and transversely between the opposite edges of the piece 48. The fold line may be formed in any suitable manner such as described with respect to the fold lines 26 and 34 of the preceding embodiments. Also, another fold line 64 extends along panel 52 only, in parallel spaced relation to the row of perforations 58. In a similar location on panel 50, a row of severing perforations 66 extends between the fold line 62 and the outer severed edge 68 along which the piece 48 has been separated from the next adjoining similar piece.

The perforations 66 define a small piece of waste material 70 which is defined at its outer edge by the perforations 58. After the piece 48 has been severed from the mounting strip 54, the waste piece 70 then may be quickly removed along the line of perforations 66 from panel 50 and the panel 50 then is in condition to be folded along the fold line 62 so as to overlie panel 52. A foldable sealing flap 72 is defined by the fold line 64 and the adjacent outer edge of panel 52. A stripe of sealing adhesive 74, of suitable type, is applied to the sealing flap 72 either in a continuous line or interrupted dots of the same which may also extend along the waste piece 70. For convenience, the adhesive 74 may be of the moistenable type so as to simplify the construction.

The panel 50, for example, also has stripes 76 and 78 of sealing adhesive applied preferably continuously along the severed edge 68 and the side edge which is parallel to and opposite the row of perforations 66 in panel 50. The strips of sealing adhesive 76 and 78, especially for simplicity, also may be of the moistenable type. When activated, and the panel 50 is folded along the line 62 onto panel 52 so as to immediately overlie the same, the moistened adhesive stripes 76 and 78 will firmly adhere to the adjacent edges of panel 52 and thus form an enclosing type mailing piece which is then open only at the end to which the sealing flap 72 is connected.

As in regard to the preceding embodiments, one surface of the mailing piece 48 may have spaces for correspondence and the indication of certain things to be ordered such as sizes, dimensions, etc., and the inclusion of the senders name and address. Upon the forming of the mailing iece into an enclosing type arrangement as described immediately above, certain enclosures may be inserted within the piece through the open end thereof and then the sealing flap 72 is folded over onto the outer surface of panel 50 which then is uppermost and activation of the adhesive 74 then firmly seals the flap 72. As in regard to the foregoing embodiments, the address of the advertiser usually is printed on the outer surface of one of the panels 50 or 52.

Referring to FIGS. 10 and 11, a further embodiment of mailing piece 80 is shown which has a mounting strip 82 provided with feeding perforations 84 along the same, as well as a severable row of perforations 86 and a stripe of mounting adhesive 88, all similar to corresponding elements in the above-described embodiments. In this embodiment, it is preferred that the fold line 90 be parallel to but arranged closer to the severed end 92 of piece 80 than the opposite severed end 94. This results in panel 96 being smaller than panel 98. A stripe of readily activatable sealing adhesive 100 extends around the opposite side edges and outer end of panel 96.

When the adhesive has been moistened or otherwise suitably activated, and appropriate blanks or otherwise formed on the upper surface of panel 96, for example, have been appropriately filled in with the senders name and address, suitable enclosures such as coins 102 may be placed upon panel 98 near the fold line 90 and then covered by panel 96. Said enclosures then will be sealed between the overlying panels 96 and 98 by the stripes of sealing adhesive 100 as shown in exemplary manner in edge view in FIG. 11. As in regard to the preceding embodiments, the address of the advertiser usually is printed on the outer surface of panel 98, for example, to render mailing of the same relatively effortless.

Referring to FIG. 12, a mailing piece 10' is shown which is somewhat similar to the mailing piece shown in FIGS. 1 and 2, whereby similar reference characters have been employed for all elements and features which are common to the mailing pieces shown respectively in FIGS. 1 and 12. In the mailing piece 10 shown in FIG. 12, however, essential differences comprise the means for determining the location of the fold lines upon which panel 24 is folded upon panel 22 and sealing flap 32 is folded upon the superimposed panels 22 and 24 and the arrangement of the foldable panels relative to the mounting strip 14. As has been mentioned hereinabove, it is not essential that weakening lines or creases be provided. Instead, as shown in FIG. 12, notches 104 may be formed in the opposite ends 12 of the mailing piece 10 so as to extend inward from said ends formed when the mailing piece is severed from the next one on the connected strip thereof along the line or perforations 12 and also separated from mounting strip 14 along perforations 16. It readily can be visualized from FIG. 12 that an imaginary fold line 26 will extend between the notches 104 and the weakening of said edges by said notches will facilitate the determination of the fold line without the actual provision of weakening means or creases to indicate the same as otherwise suggested with respect to the weakened type fold line 26, for example, in the embodiment shown respectively in FIGS. 1 and 4.

Similarly, an additional pair of notches 106 are formed respectively in the opposite ends 12 of the piece 10 as described hereinabove with respect to notches 104. The notches 106 are slightly spaced from perforations 16 to define an imaginary fold line 34 by which the sealing flap 32 is folded with respect to panel 22. However, notches 104 and 106 primarily are exemplary.

In FIGS. 13 and 14, a still further, relatively simple embodiment of mailing piece is illustrated. Essentially, this embodiment differs from the preceding embodiments in that no sealing flap is formed on one end of the mailing piece 108. Preferably, the foldably connected panels 110 and 112 thereof are of substantially equal size and the same are arranged to be folded into superimposed relationship along the fold line 114. As in regard to the preceding embodiments, a mounting strip 116 is detachably connected to the piece 108 by a row of perforations 118.

The attaching strip 116 also is provided with appropriate feeding means such as the row of feeding perforations 120. Also, an attaching stripe of mounting adhesive 122 extends along the attaching strip 116 as in regard to the preceding embodiments. Also as in regard to the preceding embodiments, it is to be understood that the panels 110 and 112 may be utilized for purposes of writing or typing messages, names and addresses, etc., order identifications and the like for purposes of transmitting the same to an addressee, whose name and address usually is printed on the outer surface of one of the panels 110 or 112.

After severing the mailing piece 108 from its attaching strip 116 along the line of perforations 118, and after any writing or typing has occurred on the panels involved, the panel 110 then may be folded along the line 114 onto the panel 112. In order to seal the overlying, adjacent side edges of said panels together, only one of said panels, such as panel 110, is provided adjacent its opposite side edges with stripes of sealing adhesive 124 which, particularly for simplicity, may be of the moistenable type to render the same active. Upon sealing the side edges of the panels 110 and 112 together by means of the stripes of adhesive 124, an envelope-type structure is provided which 10 is still open along the adajacent and overlying severed end edges 126.

Any desired inserts then may be disposed through said open end of the srtucture prior to activating a sealing stripe 128 of appropriate adhesive which extends adjacent the edge 126 of panel 112, for example. To facilitate such insertion, as shown in FIG. 14, the outer edge of one of the panels extends slightly beyond th other to facilitate spreading said edges apart transversely. Said adhesive is of the same type as the stripes 124. Particularly if of the moistenable type, final sealing of any contents within the thus-formed scalable type enclosure then is completed. Such completed and sealed configuration is illustrated in end view in FIG. 14 and it will be seen from this that the outermost severed edges 126 of both the panels are substantially in coincidence with each other. Under the circumstances, the need for a sealing flap is obviated.

In regard to all of the above-described embodiments in which the stripes of sealing adhesives are indicated as preferably being of the moistenable type, for example, it is to be understood that at least with appropriate modification and provision of protective strips which are lightly and peelably adhered to the stripes of sealing adhesive, other types of adhesive than the contact and moistenable types may be employed, such as pressure-sensitive adhesive. Also, where weakened type fold lines are shown, notches of the type shown in FIG. 12, to locate the fold lines, may be used in lieu thereof.

In addition to the relatively simple type of protective strips of material such as strips 38 and 40 in the embodiment shown in FIGS. 4 and 5, somewhat more sophisticated types of protective strips and especially means to facilitate the removal thereof from the strips of adhesive are illustrated in subsequent embodiments which are illustrted in FIGS. 15-21, the principal one of these additional embodiments being shown in FIGS. 15-18. Details of the structure shown in these figures are as follows.

Referring particularly to FIG. 15, it will be seen that the mailing piece 130 preferably is at least initially flat and of uniform width. At least along one edge thereof is a combination mounting and feeding strip 132 which, preferably, is provided with exemplary feeding means such as a row of feeding apertures or perforations 133. The mounting 132 also is detachably secured to one edge of the mailing piece 130 by a row of readily separable perforations 134. Also extending transversely between opposite edges of the mailing piece 130 is a fold line 136 which divides the piece into two panels 138 and 140.

The panel 140 also is provided adjacent the outer end 142 thereof with another transversely extending fold line 144 which preferably is similar to and formed by the same type of means as the fold line 136. The fold line 144 defines a closing flap 146. Preferably, the portion of panel 140 between the fold lines 136 and 144 is only slightly longer than the panel 138 in the direction of the major axis of the flat piece illustrated in FIG. 1, so that the panels are substantially equal but permit ready folding of the flap into fully closed position.

The mailing piece 130, particularly when provided with the mounting strip 132 thereon, is readily adapted to be affixed to a supporting or carrying piece such as a printed web of the type referred to above. The mailing piece 130 primarily is intended for use as an enclosing type mailing piece associated with certain advertising matter and intended to be removed by a reader and folded into an envelope-like item for the mailing of an order in conjunction with the advertisement and, more particularly, to afford such an envelope-type mailing piece in which, for example, payment in suitable form for merchandise may be enclosed and fully sealed. The mailing piece 130, in fiat and single sheet thickness condition, is secured to such supporting means by a stripe of adhesive 148 secured to one surface of the mounting strip 132. Said stripe of adhesive 148 is shown in full lines in the upturned 1 1 corner portion of the mounting strip 132 as viewed in FIG. 17.

Transversely extending lines or rows of several means 150 are formed between adjacent fiat mailing pieces 130 in order that said strip of mailing pieces may be arranged in compact, overlying relationship either for shipping purposes, storage, or for delivery to suitable feeding, severing and applying machines such as the type comprising the subject matter of said aforementioned pending patent application, Ser. No. 685,122. One appropriate arrangement of such connected strip of flat mailing pieces 130 is illustrated in FIG. 22 in which said pieces are arranged in so-called fan-fold disposition. In FIG. 23, said strip of mailing pieces 130 is shown as being arranged compactly in coiled or roll formation. Still other arrangements are possible in accordance with the principles of the present invention.

After individual mailing pieces 130 are separated from the mounting strip 132 therefor, means are provided by which the panels 138 and 140, when folded into overlying position upon each other along the weakening line 136, for example, may be firmly secured together at the outer edges thereof. To effect this, each of the mailing pieces 130 is provided adjacent opposite edges thereof with a preferably continuous narrow stripe of sealing adhesive 152. One of said stripes is illustrated in partially exposed manner in FIG. 16. Said stripes of adhesive are applied to the same surf-ace of each mailing piece 130 and said adhesive may be either of the moistenable, contact, or pressure-sensitive type, as desired. If the adhesive is of the contact type and even more particularly if it is of the pressure-sensitive type, suitable prtoective means for the same are provided.

Particularly when the sealing adhesive is pressure-sensitive, the present invention provides protective means for said stripes of adhesive in the form of extra covering strips 154 which are preferably of a paper-like material and are of such nature or otherwise are prepared so that they only lightly adhere to the stripes of adhesive and thus are readily removable therefrom simply by pulling upon one end of each covering strip, thereby exposing the stripes of adhesive beneath the same. Means to facilitate such removal of the strips are described in detail hereinafter.

'When the covering strips 154 have been removed from the stripes of adhesive 152, and the panel 138, for example, is folded along the fold line 136 onto panel 140, so as to evenly overlie the same, it will be seen that the stripes of adhesive respectively on said panels will also overlie and respectively contact themselves. Especially where pressure-sensitive or contact-type cements are used, such engagement immediately firmly secures together the opposite end portions of the panels to form a pocket.

To secure items desired to be sealably enclosed within the envelope-like mailing piece, the closing flap 146 is folded alongjthe fold line 144 into engagement with the outer surface of the adjacent end of panel 138, for eX- ample. To secure said flap 146 in such closed position, several embodiments of adhering means are provided. One of these comprises an elongated area or stripe of adhesive 156 which, for example, may be of the moistenable type. Supplementary securing or adhering means for the closing flap 146 are described hereinafter.

To facilitate the removal of the covering strips 154 from the stripes of adhesive 152, removal or pull tabs 158 may be proided. Such tabs preferably comprise corner portions adjacent opposite edges of the outer end of panel 138, for example. As illustrated in FIGS. and 20, one embodiment of such tab is shown as being triangular. Said tabs are formed by either partial or complete incisions such as the diagonal incisions 160. If desired, such incisions, rather than being a continuous cut, may be in the form of perforations. In either event, however, the incisions should be such as to lend the tabs 158 to ready separation from the panel 138, for example, when 12 it is desired to remove the cover strips 154 from the stripes of adhesive 152 therebeneath.

The triangular type tabs 158 as shown in FIGS. 15 and 20 are defined by either a straight cut or incision 162, which may be coincident with the line of perforations 134 as shown in FIG. 20, or, as shown in FIG. 15, the line of perforations 134 may suifice to define the outermost edge of the tabs 158 at the left-hand side of the panel 138 as viewed in FIGS. 15 and 20. With respect to the opposite tab 158 adjacent the right-hand side of the panel 138 as shown in FIG. 15, the outer edge of the tab will comprise the outer edge of the sheet from which the mailing piece is formed.

As shown in FIG. 21, the exemplary tab 158' shown therein is illustrated as being somewhat rectangular. Such tab may be defined by a transverse straight cut 164 or incision of limited length extending between the row of perforations 134 and the short row of perforations 166 parallel thereto and extending between the outer end of panel 138 and the incision 164. If desired, the short row of perforations 166 may be replaced by a straight or continuous cut or incision.

Also, in regard to forming the rows of perforations or straight cuts or incisions defining the various types of pull tabs 158 and 158' illustrated in the drawing and described hereinabove, it is to be understood the same may be applied to the stock strip of material from which the successive mailing pieces 130 are formed incident to otherwise forming said pieces upon suitable machinery including the application of printing to one or both surfaces of the mailing pieces 130, including the mailing address of the advertiser and the application of suitable paid postage indications thereon.

The use of removal or pull tabs 158 and 158' in the form of corner portions of the panel 138 of the mailing piece, for example, in addition to serving as means to facilitate the removal of the covering strips 154, also provide an additional useful feature of the present invention which is best illustrated in FIG. 18. It will be seen that when the panel 138 has been folded upon the other panel 140 which is beneath the same as viewed in said figure and the side edges thereof have been secured together by the overlying stripe of adhesive 152 along each of the opposite sides thereof, the diagonal cut line at the corners of the panel 138 expose an appreciable portion of the stripe of adhesive 152 on panel 140. In addition, the inner surface of the closing flap 146 likewise has a continuation of the same stripe of adhesive 152 thereon. Accordingly, when the endmost portions of the closing flap 146 are pressed downwardly into engagement with the panel 138, said exposed portions of the adhesive 152 will overlie and engage each other in sealing manner, thereby augmenting the securing function of the other stripe of adhesive 156 described above as being in the inner surface of the closing flap 146 when the same is folded into overlying relationship upon the outer surface of panel 138.

When the mailing piece has been completely folded and sealed into enclosing condition, it can be appreciated particularly from FIG. 19, which is a view of the so-called rear side of the mailing piece that is opposite from that which bears the address of the advertiser, for example, that the closing flap 146 will be adequately secured in sealed condition. The position of the stripe of adhesive 156 relative to the overlying portions of the stripes of adhesive 152 at the upper end of the enclosure assures such firm sealing of said closing flap.

One additional convenient feature is provided in the mailing piece 130, as well as in certain preceding embodiments, in the form of additional rows of perforations 168- which are parallel to and closely adjacent the innermost edges of the stripes of adhesive 152 which extend along the opposite side edges of the mailing piece, including both panels 138 and 140 as well as closing flap 146. When the mailing piece has been completely folded into the condition shown, for example, in FIG. 18 as well as in FIG. 19 and sealed, which is the condition in which the same is mailed, it will be seen that the rows of perforations 168 are conveniently located to permit ready removal of the connected and sealed opposite ends of such folded and sealed mailing piece 130 in order to expose the contents thereof as when the advertiser has received the mailing piece in the form of an order and enclosures therein are to be removed, in addition to exposing to view the written order on the interior. of the mailing piece. Though two rows of perforations 168 are illustrated, it is to be understood that either only a single row may be used if desired, or a third row may be provided along the third sealed edge to facilitate opening the piece.

While the invention has been illustrated and described in its several preferred embodiments, it is to be understood that the invention is not to be limited to the precise details herein illustrated and described since the same may be carried out in other ways falling within the scope of the invention as shown and described.
