One-piece mailer and apparatusforfolding same
This invention relates to a one piece mailerandto an apparatusforfolding a one-piece mailer. More particularly, this invention relates to a one-piece mailer, an assembly of one-piece mailers and an apparatusforfolding and sealing a one-piece mailer.
Heretofore, various types of one-piece constructions have been known forthe fabrication of a mailer. For example, U.S. Patent4,055,294 describes a continuous web from which a series of connected one-piece assemblies are constructed. In this case, various lines of perforations are provided in the web so that the web may be folded about a longitudinal score line so that one portion overlies another portion of the web in order to define return envelope pockets therebetween. Other lines of perforations are also provided to permit the remaining web portion to be folded overthe previouslyfolded portions to form a series of three-ply mailers. In this construction, use is made of a previously applied hot-melt adhesive in orderto securethefolded over portions together.
Other types of assemblies have also been known wherein various plies of a mailer arefolded overon each other and secured in place by an adhesive.
However,these adhesives tend to be hot melt adhesives or other heat activated adhesives.
In the case where users process streams of mailers, for example of the interconnected type, through laser printers, a difficulty arises in the subsequentfolding and sealing of the mailers into a condition suitable for mailing. Specifically, the folding equipment requires some form of heater in order to activate the hot melt glues so as to form a sealed envelope. Such constructions tend to be relatively costly.
Accordingly, it is an object of the invention to provide a one-piece mailer of simple construction which can be readily folded and sealed in a simple, economical manner.
It is another object of the invention to provide a simple and economicapparatusforthefolding and sealing of one-piece mailers.
Briefly, the invention provides a one piece mailer blank having contiguous sections disposed for folding over on each other and wherein each section has a pair of remoistenable glue strips along the respective longitudinal edges for bonding the facing sections togetherwhen folded. The mailer may be constructed with two or three foldable sections. In addition, the mailer blank may be provided with one or two transverse fold lines to permit subsequent folding of a blank into a two-ply mailer orthree-ply mailer.
The one-piece mailer may also have remoistenable glue disposed near a transverse edge for bonding to the other sections. Whether the mailer is a two-ply orthree-ply mailer, this glue serves to seal the mailertransversely across the mailer without leaving a gap which might be inadvertently opened.
The invention also provides a mailer assembly having a plurality of interconnected one-piece mailer blanks which are separated from each other by transverse burstabie lines of weakening. In this respect,the mailer assembly is of one-ply construction and is provided with removable strips of control holes along the longitudinal edges to facilitate feeding through various types of automatic machinery, forexample, a laser printer.
Afterthe mailer assembly has been processed, for example, through a laser printerwhich provides the mailerwith information, such as an address of a recipient, address of a sender and other information, each mailer blank is separated from the assembly, if continuous, by bursting along a transverse line of weakening. Thereafter, water is applied to the edges of each mailerto activate the glue strips and the blank is folded with the folded over sections being pressed together in order to effect a bonding ofthe sections tog ether via the water-activated glue strips.
When the blanks also have glue along a transverse edge, this glue is also activated by the application of water along the transverse edge prior to folding of the blank. When the blank is folded, the remoistened glue effects a bonding of the transverse edge to a facing mailer section.
The invention also provides an apparatus for folding and sealing the mailer blanks into mailers.
This apparatus includes a feed means for receiving and conveying a one-piece mailer blankwith remoistenable glue strips thereon, means for applying water to at least one side ofthe conveyed mailerblankalong each longitudinal edge in orderto activate the glue means for folding the sections of the mailer blank into overlying relation while pressing the opposed longitudinal edges together in orderto permit the activated glue strips to bond the edges together and form a sealed unit.
The folding apparatus may be of generally conventional structure modified to have a means for applying water to the edge areas of the conveyed mailer blanks. In this regard, the means for applying the water may include a water reservoir disposed below the conveyed mailer blanks and an applicator, such as a rotatably mounted wheel or capillary brush, for transferring water from the reservoir to the underside of a conveyed blank. Alternatively, the means for applying the water may include a water reservoir and a nozzle which communicates with the reservoir and is directed towards a conveyed blank for transferring water to the conveyed blank by pressure or by gravity.
Where the blanks are provided with glue along a transverse edge, the folding apparatus also includes a similar meansfor applying waterto the conveyed blanks along the transverse edge.
These and other objects and advantages of the invention will become more apparentfrom the following detailed description taken in conjunction with the accompany drawings wherein:

Referring to Figure 1, the one-piece mailer is formed from a fiat blank 10 of rectangular shape which is divided into three longitudinally disposed contiguous sections 11,12,13 bytransversefold lines 14, a a pair of longitudinal perforations 16, or other like lines of weakening extended along the blank 10 approximately one-half (1/2) inch from the respective longitudinal edges. Each section 11, 12,13 is also provided with a pair of remoistenable glue strips 17 along and between each respective longitudinal edge and a perforation 16. For example, each glue strip is 1/2 inch wide for a blank having a width of 112 inches. The remoistenable glue is made of any suitable glue which can be reactivated with water such as a vinyl copolymerdispersion adhesive.
Referring to Figure 5, the mailer assembly 18 is formed of a plurality of interconnected one-piece mailer blanks 10which are separated bytransverse burstable lines of weakening 19. In addition,the assembly 18 includes longitudinal strips 20 which are provided with control holes 21, for example for feeding through a laser printerforthe application of information to the various mailer blanks 10.
As indicated in Figure 1, each mailer blank 10 can be imprinted with information such thatthe upper two sections 11, 12, as viewed,form a voucher including the address of a recipient while the lower section 13 is printed as a check. In this case, the lower fold line 15 is made as a line of weakening, e.g., a perforation, to permit the section 13to be subsequently separated from the section 12. In addition,the backside ofthe mailer blank 10 may be provided with information, such as the return address of a sender, for example in one corner of the middle section 12. In addition,the middle section 12 may be provided with a cut-out 22 and an overlying plasticfilm 23 to permitviewing of a printed address of the recipient on one section 13.After feeding the mailer assembly 18through the printer, the longitudinal strips 20 may be removed and, thereafter, the individual mailer blanks 10 can be
separated from the assembly 18 by bursting across
the lines ofweakening 19.
After being burst from the mailer assembly 18,
each mailer blank 10 can be delivered to a folding
and sealing machine or apparatus 24. In this regard,
as indicated in Figure 6, the machine 24 includes a tray 25 for receiving a stack of mailer blanks 10,
means 26 for applying waterto at least one side of the blank 10 along each longitudinal edge in orderto
activate the glue and means (not shown) for folding the sections 11,12,13 into overlying relation while
pressing the opposed or facing longitudinal edges together to permit the activated glue strips 17 to bond the edges together.
The machine 24 is of conventional structure and
need not be further described. For example, in the
case of a machine sold byA. B. Dick as a Desk Top
Folding Machine, Model 52, a feed means 27 in the form of a friction feed roller (Figure 2) is provided to
individually convey the blanks 10 from the tray 25.
The means 26 for applying water includes a pair of water reservoirs 28 each of which is mounted on the machine 24, a plastictube 29 for delivering water from the reservoir 28 and an applicator 30 for transferring waterfrom the respective reservoir 28 via the tube 29 to the edge of the conveyed blank 10.
In this regard, as indicated in Figure 2, each blank 10 is conveyed with the glue side facing the respective applicator 30.
Referring to Figure 2, each water applicator 30 is in the form of a rotatably mounted wheel 31 which is capable of picking up water from a reservoir 32 for application to the underside of the blank 10.
Alternatively, as shown in Figure 7, the applicator may be a brush 33 which extends upwardly from the reservoir 32 for wetting the conveyed bla nk 9 by capillary action.
As indicated in Figure 8, the water applicator may be in the form of a nozzle 34 which communicates with the reservoir 32 so as to spray water onto the blank 10. Still further, as indicated in Figure 9, the reservoir 32 may be disposed above the plane ofthe blank 10 so that water is fed by gravity th rough the nozzle 34.
Referring to Figure 3, the means for folding the sections 11, 12, 13 of the blank 10 is of conventional structure which employs folding plates which function to fold the blanks 10 on each other to form a three-ply mailer 35, for example, as shown in Figure 4. The mailer 35 can then be mailed in a conventional manner.
As indicated in Figure 3, once the glue strips 17 have been activated by the application of water, the check forming section 13 is folded up againstthe middle section 12 with the respective glue strips in facing relation to each other. Thereafter, the remaining section 11 can be folded up so that the glue strips 17 thereon face a n u an unglued surface of the section 13. During pressing of the sections together along the edges, the glue serves to bond the sections together into a sealed unit atthe ends of the mailer 34.
Of note, depending on the folding machine, the waterapplicators may be positionedto applywater to the downside of a blank as in Figure 2 orthe upside of a blank, In either case, the glue strips would be in facing relation to the applicators.
Referring to Figure 4, when a recipient receives the mailer 35, both edges may be torn off along the overlying perforations 16 so as to permit the remainder to be opened flat. The lower section 13 can then be removed along the perforations 15 where made as a check.
Referring to Figure 11, wherein like reference characters indicate like parts as above, the mailer blank 10 may also be provided with remoistenable glue intheform ofa cross-web array ofgluedots 17' disposed near a transverse edge, i.e. thetop edge as viewed, of the upper section 11. These glue dots 17' are made ofthe same glue as the glue strips 17.
Alternatively, the dots 17' may be replaced by blocks or a line of glues.
Referring to Figure 10, the machines 24 mayalso include means 26'forapplying watertothe blank 10 along a transverse top edge, as viewed, in orderto activate the glue dots 17' which may be present as shown in Figure 11. In this case, the water applying means 26' includes a reservoir 28' which is mounted attheupperendofatray35forthefolding means (not shown).
As above, a plastic tube 29' extends from the reservoir 28' to an applicator (not shown) positioned under and in line with holes 36 in the tray 35 in order to transferwaterto the leading transverse edge of a conveyed blank on which the glue dots 17' are disposed. As indicated, suitable stops 37 are provided to stop movement of the blanks from the tray 35.
After a blank 10 has been moistened along two longitudinal edges and the one transverse edge, the sections 11, 12, 13 are folded and pressed, as above, with the remoistenable glue dots 17' ofthe top section 11 facing and bonding to the unglued surface of the checkforming section 13. A completely sealed unit is then obtained, i.e. a unit which is sealed atthe sides as well as across the top (or bottom as the case may be).
Referring to Figure 12, the one-piece mailer38 may be provided with lines 39 of remoistenable glue ratherthan stripes of glue as illustrated in Figure 1.
Further, a transverse line 40 ofglue may also be provided at the upper edge.
As indicated in Figure 12, the mailer blank 38 may also be shaped in a manner so that the lowertwo sections 41,42 form the front and back of a return mailerwhiletheuppermostsection43formsaflap for closing the return mailer. In this case, the lower sections 41,42 are separated by a transverse fold line 44 while the flap 43 is separated from the section 42 by a similar transverse fold line 45.
The flap 43 may be shaped as illustrated so asto have two shouldered portions 46 above the fold line 45 and a contoured closing portion 47 containing the transverse line 40 of glue.
The mailer 38 may be folded in a similar mannerto the mailers described above with respect two Figure 10. In this case, each mailer 38 is moistened along the longitudinal edges as well as along the upper edge to activate the remoistenable lines 39,40 of glue. During folding, the lower two sections 41,42
are folded together about the fold line44whilethe
flap section 43 is folded down over the backofthe lower section 41 to form a closed mailer which can then be mailed in the usual manner. One advantage
of this construction is thatthe resulting mailer has the appearances of a conventional envelope.
As an alternative, the individual mailers may be
"chopped" from a continuous web of paper so that the contour of the upper edge forming the flap section 43 is cut at the same time as the lower edge is
being cut. In this way, not only is the flap section formed with a contour shape, but also the lower edge is formed with a recessed portion of mating shape. Thus, when the mailer is subsequently opened by means oftheflap being peeled back or otherwise removed, the recess provides access into the pocket formed by the remaining two sections of the mailer.
The invention thus provides a relatively simple apparatusforthefolding and sealing of one piece blanks into a mailer construction. Further, sincethe apparatus requires a rather inexpensive water applicator, the overall costs of making and using such an apparatus are ata relativeminimum,for example as compared with folding equipment which require heaters in order to activate a hot melt glue on a mailer blank. Still further, since a remoistenable glue can be used, the costs offabricating the one-piece mailer can be held to a minimum.
