8 Claims. CL 229 69) The invention relates to pocket envelopes and methods of making the same, and more particularly to a pocket envelope which may have either one or a plurality of pockets and which may be i made either singly, or in groups or clusters, on

usual printing presses.

Single and duplex pocket envelopes are widely used by religious or other organizations as a means through which collections or contributions 19 may be made and collected; but such pocket envelopes heretofore used have required special folding and gluing machinery to be used in their production; and have always been made in single units, which are then gathered together and l packed, for distribution by the recipient organization to the donor-user.

Accordingly, the cost of making and packing such envelopes is high because of the special equipment involved; and individual envelopes of zo the group packed together frequently become disarranged or lost during the period of time, usually one year, through which their use is intended to extend.

It is therefore an object of the present inven- 25 tion to provide an improved pocket envelope construction which may include either one or a plurality of pockets..

lt is a. further object cf the present invention to provide an improved pocket envelope construction which may b'e readily made in an inexpensive manner upon usual printing presses.

It is a further object of the present invention to provide an improved pocket envelope construction having either one or a plurality of pockets,

which envelopes may be grouped or clustered together in an initially joined relation adapted for ready detachment of individual envelopes when and in the order desired; and a plurality of which groups or clusters of envelopes may be assembled together in calendar or banner form.

And finally, it is an object of the present invention to provide new methods of making single or duplex, individual or clustered pocket envelopes from sheet material on usual printing presses,

which methods do not involve any special folding operations, and which only involve simple operations that may be readily and inexpensively carried out on the usual printing presses.

'Ihese and other objects may be obtained by the articles, products, envelopes and the like, hereinafter described in detail and claimed, preferred embodiments of which are shown in the drawing, which may be described in general terms as including in pocket envelope construction, a sheet of paper or other fibrous material having a of a sheet of gummed paper;

gummed or adhesive surface, a zone of said surface being de-adhesitized, a second sheetof paper or other fibrous material sealed laround its periphery to said gummed sheet .and''having a slit therein forming a flap opposite a gummed portion of said gummed sheet and having another portion adjacent to the flap opposite the de-adhesitized portion of said gummed sheet; and said improved products may be made by the improved methods hereinafter described in detail and claimed, preferred steps of which are diagrammatically shown inthe drawing, and which may be stated in general terms as including in a method/ of making pocket envelopes, the steps of deadhesitizing a portion of a gummed or adhesive surface of paper or other fibrous material, preferably applying a thermo-plastic material to portions of said sheet surrounding said de-adhesitized surface, and sealing a second sheet of paper or other fibrous material to the thermo-plastic material on said gummed surface preferably by the combined action of heat and pressure.

The gummed sheet with vde-.adhesitizedzones through fa printing press for printingon both surfaces `thereof a series of criss-crossed lines 18 surrounding the de-adhesitized zones 17, but leaving a gummed zone 16a still present adjacent one portion of each de-adhesltized zone 17, as best shown in Fig. 5. The material 18 applied by this printing operation is a thermo-plastic material and may be a mixture` of ve parts of resin, one part of glycerine and four parts of honey. However, it is understood that the thermo-plastic material 18 may comprise other materials` or other proportions of the said materials.

The gummed sheet having deadhesitized and thermo-plastic material between two sheets of paper or other ilbrou's material 19, as by inserting the sheet 15 in a folded sheet of paper'.

the combined action of heat and pressure, which plasticizes the thermo-plasticl material, causing it to sof/ten the glue of the vgummed sheet thereunder -so that the sheets- 19 are conglutinated or sealedto the sheet 15 at their peripheries where thermo-plastic material 18 has been applied to the 'sheet 15, as best shown in Figs. 'I and 8.

The paper sheets 19 before .being sealed to the witha plurality of die cut slits 20 forming flaps-'20a therein, which flaps y"when the sheets 19 are conglutinated to the sheet 15, are opposite the gummed zones 16a on the sheet 15. i l

The conglutinated sheets are then passed through a printing press to provide printed material 21 thereon, asshown in Fig. 9, it being understood that this printing operation may be performed upon the sheets 19 either before or after the sheets 19 are sealed'to the sheets 15, and either before or after the slits 20 are provided therein.

The conglutinated sheets may then be again passed through a perforating machine or a regular printing machine to perforate the same at v22 so as to divide the sheet intova plurality of duplexr pocket envelopes 23 clustered or grouped together envelopes for special purposes.

zones is then assembled The assembled sheets 15v and 19e'. are then'passed through a printing press having in a convenient semipermanent, but detachable manner, as shown in Fig. 10.

. Thus, by carrying out the improved method, a

.and wire bound through the binder strips 25'to form a calendar or banner comprising sixty duplex envelopes which maybe numbered and dated.l Thus, the same may be used as a one year envelope contribution system by' lreligious or other organizations, each page24 providing for three months or thirteen weeks with two extra `When it is desired to use one of the duplex pocket envelopes, the proper one is detached from the calendar kpage 24 by ripping along the perfo- A rations 22. The ap 20a on each side of the duplex envelope 23 may then be vturned back and a coin or other contribution may be inserted in each vpocketofthe envelope formed between the outer sheet portions 19 and the de-adhesitized zones of the center sheet-'15. Thereafter, the inner surface of each vflapv 20a may be moistened and pressed against the gummed zone 16a to seal they pocket envelope.

1t is to be understood that the above method of making the duplex envelopes may be carried out by applying a liquid gum instead of a thermoplastic materiall at the zones 18 and then sealing the sheets 15 and 19j together while the gum is still moist. Likewise, moisture may be applied to the gummed sheets l5 at the zones 18 and the sheets 19 may then be sealed to the sheets 15 while the gum is still moist. However, such steps involve more complicated printingV operations than is encountered when a thermo-plastic material is utilized, because the use of thermo-plastic vmateriaal permitsl the sheets 15 and 19 to be conglutinated at tli'e zones 18 by the application of heat and pressure without .theexternal applicavtion of additional moisture or other fluid.

Moreover, it is to be understood that the sheets l5, instead `of being initially gummed throughout and then having sones thereof de-adhesitized, may be gummed by omitting applying gum at the zones 17. However, such procedure is also complicated and 'the improved pocket envelopes may y be more easily and inexpensively made by using full gummed sheets and de-adhesitizing zones thereof.

It is clear, that when it is not desired to produce duplex pocket envelopes, that single pocket envelopes may be made by carrying out the method described above, utilizing a sheet gummed on one side only and then conglutinating asingle sheet thereto after zones of the gummed sheet have been de-adhesitized.'

It-is likewise to be understood that either single or duplex-pocket envelopes may be made individually if desired, rather than in groups or clusters, or maybe made in groups or clusters and thereafter severed to provide an individual duplex -pocket envelope 23" as shown in Fig. 11, or an inzones 18 of the gummed surfaces of the sheets isor 15, with the naps 20a adjacent a r'emaining` gum f zone 16a.

The duplex pocket envelopes 23' may be printed with any desired copy, as described above, and may be readily sealed by moistening the `linner surfaces of the flaps 20a, which when closed stick to the gummed zones 16a. Y

Likewise, the single pocket envelope 23a comprises a sheet 15 gummed at 16 on one side only and provided with a de-adhesitized zone 17 and a thermo-plasticized zone 18, a single cover sheet 19 being conglutinated to the thermo-plasticized zone 18 of the gummed sheet 15. A flap 20a is provided in the sheet 15 by the slit 20, which lflap 20a is opposite a gummed zone 16a. in the sh'eet 15.

Accordingly, the improved method provides an inexpensive manner of making single or duplex individual or clustered pocket envelopes from sheet material on usual printing presses without involving any special folding or other operations.

Likewise, the improved single or duplex pocket envelopes, in either individual or grouped or clustered form, may be used for making contributions in a sure and safe manner without loss of contribution from the envelope and without directlyv moistening a gummed surface, it being necessary only to moisten the ungummed flaps 20a for sealing the improved envelopes.
