1 ,Claim. (01. gee-'72) This invention relates to envelope constructions and more-especially -to envelopes having ,a plurality of discrete-sections orpockets on the .in-

"terior thereof.

Aprincipal object is to provide a novel blank for forming amulti-section envelope.

Another objectrelates-to'an envelope having a pluralityof Separate partitionedsections on the interior and a' common sealing flap, all of which are formed from a single foldable blank. This arrangement avoids the necessity of employing partition members which are cut separately from the envelope blank -per se, and: also. avoids the necessity of a" separate assembling and fastening operation between the individual partitionsand the body of the envelope.

A further objectis. to provide an improved blank for a multi-section envelope which can be manufactured on standard envelope making machines.

A feature of the invention relates to an envelope having a plurality of discrete pockets or compartments on the interiorithereof.

Another feature relates to animpr-ovedmail- "ing envelope and the like having threediscrete. pockets -or compartments which are formed from asingleblank.

. A further-featurerelatesto a mailing envelope and the"like--having a-plurality ofindividual pockets or compartments on the interior, the envelope having a main sealing flap for all the pockets and an auxiliary sealing flap for certain of the pockets only.

A still further feature relates to the novel organization and arrangement of parts which cooperate to provide a multi-section envelope which can be inexpensively manufactured on existing envelope making machines.

Other features and advantages not specifically enumerated will be apparent after a consideration of the following detailed descriptions and the appended claim.

In the drawing which shows certain preferred embodiments,

Referring to Figs. 1 to 4, there is shown a blank I of paper, cardboard or other suitable 'stock'conventionally employed in the manufactureoff'envelopes. The blank is ut from ithe 'desfired' steel: to the shape shown infull lines iri'FigYhi Itis sections-3, 4; a lower flap: section constituted of a main body section}; lateralffiap .section 6, and an intervening double foldededge section I. The section lfi'spreferably provided ,with reentrant edge portions} and 9 as shown.

In accordance with the inventibmthe" section 2 constitutes the. front" or facebf "the finished envelope; .the'sec 'ons 3and 4 whenjfo1ded' over and united, formthe seek; or rear fac'e' "of the 'enf velope; the Section"5jf6l1'li'lS '3l dlVldlI1g partition I ext ding internally throughout' the lengtlipfthe e'nveop'e... ar se ti ntiromsi eifi u vr' sealing flap on the't'op of'the envelopefwhil'e the a double folded section for strengthening and closing-off the bottom edge of the envelope.

The dotted lines A, B, C, DI and D2 represent the fold lines to indicate that the folds are made in the order A, B, C, D. The several folds areall made in the same direction, that is, upwardly out of the plane of the paper. This constitutes a very important feature of the invention, in that it enables the blank to be folded on conventional folding machines, since all the folds are made in the same general direction. The upper edge of section 6 is provided with a surface strip IU of glue or other sealing composition ordinarily employed in sealing envelopes. Likewise, the edge of section 4 is provided with a strip ll of sealing glue or composition.

Fig. 2 shows the first folding step wherein the section 5 is folded upwardly along the fold line A. Preferably the edges l2 and I3 of section 5 are very slightly out on a taper so that when the section 5 is folded to the position shown in Fig. 2, it slightly clears the fold lines B and C. The sec tion 3 is then folded over to the position shown in Fig. 3, and then the section 4 is folded over and the strip l l is glued to the corresponding surface of the folded-over section 3. The final folding step comprises the refolding-over of the section I along the superposed fold lines DI, D2. The face of the section 1 is then glued to the outer surface of the folded-over sections 3 and 4 as indicated in Fig. 3. As shown in Fig. 4, the finished envelope comprises two completely separate pockets l4, 15, which are separated by the section 5 of the blank which forms a continuous partition therebetween. If desired, the original blank may be lightly scored along the fold lines to facilitate the folding operation.

Referring to Figs. 5 and 6, there is shown a modification of Figs. 1 to 4. The blank of Fig. 5 is identical with that of Fig. 1, except that the section 5 is provided with an additional lip or flap l6, which has a surface strip of glue H, and which can be folded along the line E to seal the pocket I 5 individually. With this arrangement, matter can be inserted in pocket I5 and sealed, and other matter can be inserted in. pocket l4 and sealed by the main fiap 6 which overlies the auxiliary flap I6.

Figs. 7 to 9 show a further modification, wherein the finished envelope has three separate pockets extending the full length of the envelope interiorly thereof. The blank I is substantially the same as the blank of Fig. 1, except that the lateral sections 3A, 4A, are cut sufiiciently long so as to overlie substantially the entire length of section 2. Each of the sections 3A and 4A has an individual gluing strip l8, l9, at the ends so that when the said sections 3A and 4A are folded over as described in connection with sections 3 and 4 (Fig. 1), they can be individually glued thus forming three separate pockets M, 29 and 21 (Fig. 9). The manner of folding and gluing the blank of Fig. '7 is otherwise the same as that described in connection with Fig. 1.

Figs. 10 to 12 show a further modification of Fig. 7, wherein either or both of the lateral sections 3A is provided at its middle portion with an additional gluing strip 22, 23, on opposite faces, so that when the two sections 3A. and 8A are folded over each other, they can be glued at the central region 24, thus subdividing the outer pocket into two smaller pockets 25, 26.

Thus, the finished envelope as shown in Fig. 11, comprises two pockets l4 and 15, extending substantially the entire interior length of the envelope, and two additional pockets 25 and 26, extending each approximately half the length of the envelope. The manner of folding the blank of Fig. 10 is the same as that described in connection with Figs. 1 and 7.

While certain particular embodiments have been disclosed herein, various changes may be made therein without departing from the spirit and scope of the invention.

What I claim is:

An envelope formed from a single unitary folded paper blank, said blank having a central portion to form the front of the envelope and having the same size as the finished envelope said front portion having a top wing to form the sealing flap of the envelope, and having a bottom wing of at least the same size as said front portion and arranged to be folded against said front portion to form a partition for dividing the envelope into two distinct compartments said front portion also having a pair of lateral wings each being shorter than the length of said front portion and arranged to be folded towards each other to form the back of the envelope, said bottom wing being initially folded along a line which is off-set below the lower edge of said front portion to form an overhang said overhang being refolded back on itself along the bottom edge of said front portion and sealed to said folded-over lateral wings to seal the bottom of the envelope and to provide a reinforcement therefor.
