This invention relates to' continuously attached envelopes and has particular reference to afseries vof envelopes which vare connected together-fin strip formation to permit yoffthe,convenientfeeding of the strip through a'typewriter or' addressegraph for addressing the envelopes.v

An object of the yinvention, is to provide a series of continuously attached envelopes in'which adjacent envelopes are integrally connected together by narrow tabs located adjacent the opposite ends I thereof and which narrow tabs `may be readily severed for separating the envelopes. Another object of the invention isto Vprovide a series of continuously attached envelopes in which the front and rear walls of 'each'envelope are integrally connected together at one end of the envelope and in which one of the said w-alls is formed with side flaps adhesively joining the front and rear walls together at the opposite side edges thereof. -f f" Still another vide a series of continuously attached envelopes which are so" constructed fand arranged thatthe same may be economically produced from `a single sheet or length of paper withoutlwaste'in forming the envelopes. Y r; f-, Y. y

I Still another object of vide two connected series of continuously attached envelopes arranged side by'side parallel'frelation `with the envelopes in one series connected with the envelopes inthe'other series by weakened lines topermit of the' convenient separation thereof after the envelopes are addressed. 4

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiments of the invention are illustrated. f Y

In the drawings. g

Fig. 1 is a fragmentary planview of the blank object of the invention is to pro-T QICIaims.' (Cl. 2297-69)v i' Fi'g.`r7 isf'a transversesectional` view taken approxima'tely on line 1-1 ofFigl".

the invention is to profrom which a series of continuously" attached' Y Fig. 8 isa fragmentary sectional view ftaken approximately online 4ir---ii ofFig. 61. ,e l Referring tothe drawings by characters of reference, the 'envelopesflll in continuously attached formation yare produced from van elongated strip of paper which is of any desired width and of continuous formationtoprovide any desired depth and width of envelope and any desired number thereof in' attached formation.`A The en-` velopeslil are 'Iso constructed and arranged that ai single series or two series ofcontinuously atetached envelopes may be produced from a single strip of paper. The envelopes in a single series 'or in connected series are adapted to be disposed in stacked formation `for continuously feeding the same through atypewriter or addressograph for addressing lthe envelopes. 'y y In Figs.` 1 to VVl inclusivel of the drawings, a strip'of paper II is illustrated which is 'provided with' lines-'adapted to show the` mannerin which a f'sing'le' series of envelopes I 0 are produced therefrom infacc'oifdance with the invention. The strip `vvI IA is cutaway in-rectangular'formationas at I2 at longitudinal equallyspaced locations forming oppositely disposed transversely extending edges I3 and Ill,` At theopposite ends of the cut vaway portions I2 Vnarrow tabsr I5 vand I6 are'pro'vided which-form connections joining adjacent envelopes lill -The7narrow tabsv Ieare located along a lOngitudinally--extending line I1 while the narrowjtabs I6`arelocated along the side edge I8. Between the longitudinally extending linei'l and a longitudinally"extending line i9 the strip 'is 'transversely slit at longitudinal kequally 4vspaced 4edges of the front wall 2B of each of the envelopes from which two connected series of continuously are'folded into underlying relation with the rear wall 21 thereof and `adhesively secured thereto to form a pocket between the front and rear walls. The tabs .I5 may be lprovided 'with' weakened or ,zperforatedlines 28rand'29 While the tabs IS'inay be provided with weakened or perforated lines'iac and3l topermit of convenient tearing of the tabs onsaid lines to separate' the envelopes from'series .formationl after the envelopesfhave lbeen addressed.

The strip I I is also cut away as at 32 at longitudinal spaced locations between the side flaps 22 and 23 and the side edge 33. This forms the closure flaps 34 which are folded on the longitudinally extending line I9 into overlying relation with the rear wall 21 for adhesively sealing the envelopes in closed relation.

In Figs. 5 to 8 inclusive of the drawings, a strip of paper 65 is illustrated which is provided with lines adapted to show the manner in which two series of continuously attached envelopes I are produced therefrom in accordance with the invention. The strip 35 is divided into parallel portions 36 and 31 by a longitudinally extending line 36 located medially betweenv :the opposite side edges 39 and 40 of the Astrip. Portions 36 and 31 of the strip are cut away in a rectangular formation as at 4I and 42 respectively at longitudinally spaced locations to form oppositely vdisposed transversely extending edges 43 and 44 extending inwardly from .the `side edges 39 ,and 40 of the strip portions .36 and 31 to narrow tabs 45 and 446 located along the longitudinally .extending lines 41 and 48 respectively. AThe longitudinallyextendingline 41 is located medial- 1y between the side edge 39 Aandna longitudinally extending line 49 of the strip portion 36, while the line 4 8 is disposed medially between the side edge 40 .and a longitudinally vextending line 50 of the strip portion`31. The narrow tabs =45 .and 46 provide connections xjoining adjacent envelopes I II formed from the portions 36 `and 31 of the Strip. Narrow tabs `5I are also provided which are located in lateral .alignment with the tabs :45 and 46 and disposed between the longitudinally extending lines 4 9 and 50.

The strip is transversely slit at longitudinally spaced locations as at 6 2 .between Vthe longitudinally extending lin 4] and 40 and as at 53 between the longitudinally vextending lines 48 and 0 so as Ato form oppositely disposed rectangular shaped .naps 54 and i5 in the-strip portion 3 6 and oppositely disposed rectangular shaped side flaps 56 and 51 .in the :strip `portion 31 which are `folded on the transversely .extending lines 58 and 6.9 located 'in alignment with .the Vtransversely .extending edge portions 43 and 44.

The .strip portion `3 6 is folded on the .longitudinally extending line 41 to provide the vfront walls 60 ofthe envelopes and the rear walls 6I thereof which latter walls are disposed in-overlying relation with the front walls. The side flaps 64 and 53 at the opposite edges of the front walls 60 are folded into underlying relation with the rear walls 6I and adhesively secured thereto so as to form Apockets rbetween said walls.. The strip portion 31 .is Similarly folded on the longitudix-ially uextending line 46 so .as to Aform the front walls 62 of the envelopes and the rear walls 63 thereof, which `latter walls are disposed in overlying vrelation with the front walls and have the side flaps 58 and 59 folded under :the rear walls and adhesively secured thereto .to Vform the `pockets between the .front and rear walls of the-envelopes. The tabs 45 .and 4 6 maybe provided with weakened or perforated lines 64 and 65 connecting Yadjacent `envelopes. and the tabs-5I may be provided with weakened o rperforatod lines 56 andi! 'which .form the .ends ofthe closure flaps 68 and 69 of the twoseries respectively when the envelopes are separated- The closure flaps 68 are folded on the' fold line Y48 `while `the closure flaps 6 9 are folded on the longitudinally extending Yline 50 and adhesively secured to therear walls of the envelopes in the series respectively for sealing the same.

This provides two series of envelopes in which the series are connected together by the weakened or perforated longitudinally extending line 10 joining the flaps 68 and 69 and in which the envelopes in each series are connected together by narrow tabs which permit of the folding of the connected strips in stacked formation for continuously feeding the two series through a typewriter or addressograph so that lthe envelopes disposed inside by side relation in the series may be addressed and the next succeeding envelopes `in each series moved into position in the typewriter or add-reograph for addressing the same.

The rear walls 21 of the envelopes I0 in the -formfshown .in Figs. l to 4 inclusive of the drawings .are somewhatnarrower than the front walls 26. This disposes the weakened lines 28 and 29 anni!) and 3| inwardly of the side edges 24 and 25 of the front wall so that when the tabs I5 and J6 .are ysevered along said weakened lines, the frayed edges are inwardly of the side edges of the envelope. In this jormalso the strip is slit along the longitudinally vextending lines I1 and I9 to form the endsl of .theilaps 22 and 23.
