Oct. 10, 1939. 1.. MANDELBAUM ENVELOPE Filed June 2, 1938 2 Sheets-Sheet 1 Leon Mande'lfiw BY @w %W ATTORNEYS Oct. 10, 1939. MANDELBAUM ENVELOPE Filed June 2, 1938 2 Sheets-Sheet 2 BY WWW ATTORNEY 5 Patented Oct. 10, 1939 UNITED STATES PATENT OFFICE 5 Claims.

My invention relates to improvements in en velopes, and more particularly to a dual mailing envelope.

One of the objects of my invention is to provide a novel mailing envelope which can carry two classes of mailing matter.

Another object of my invention is to provide an envelope of novel construction, having a main envelope adapted to carry printed matter, circulars or the like, and a second or supplemental envelope contained within said main envelope and adapted to carry first class mailing matter such as letters, invoices or the like.

Another object of my invention is to provide a duplex envelope having a main envelope and a second or supplemental envelope formed from an extension of the front wall of the main envelope, said second envelope being contained wholly within the main envelope and the sealing flap of the main envelope serving as the common sealing flap for both the main envelope and the second envelope.

Another object of my invention is the provision of a duel mailing envelope which can be formed from a single blank or sheet of paper or other suitable material and which is simple and economical to manufacture and sturdy in construction.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above statement of the objects of my invention is intended to generally explain the same without limiting it in any manner.

Fig. 1 is a rear plan view of the improved dual mailing envelope, part of the sealing flap being shown torn away.

Fig. 2 is a front plan view of that portion of the envelope which contains the second or supplemental envelope.

Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a perspective view of the envelope, showing the sealing flap in open position and a part of the rear Wall of the envelope rolled back to show the envelope in detail.

Fig. 5 is a plan view of the cut-out blank from which the dual envelope is formed.

Referring to the drawings, my improved envelope comprises two body portions I0 and II, body portion I0 forming the front wall of the envelope and body portion II forming the rear wall of the envelope. Sections I0 and II can be folded on each other along the scored line a. as

shown in Fig. 5. The front wall Iii is provided with a wing or extension I2 along its upper edge and said section I2 can be folded on the front wall I0 along the scored line b, thus forming the inner wall of the supplemental envelope. Section I2 can have any suitable adhesive applied thereto along its upper longitudinal edge before it is folded inwardly, so that it can be securely connected to the inner face of the front wall If). This adhesive is applied before the blank is folded. A flap II integral with section I2 extends laterally from said section I2 and the construction of flap I I will be hereinafter explained. The front wall I0 is provided along its lower edge with a flap I4 and said flap I4 can be folded on the front wall ID along the scored line 0. The lines a, b', 0, need not be scored, as they can be merely fold lines.

The front wall II] is also provided with a sealing flap I5 along its longitudinal edge and said flap I5 can be folded on the front wall Ill along the line at. Flap I5 is provided with any suitable adhesive I6 along its free longitudinal edge, as illustrated in Figs. 4 and 5, so that it can be pasted down and secured to the rear wall II of the envelope, thus sealing the envelope.

The rear wall I I is provided along its upper edge and adjacent to wing I2, with a flap H which can be folded on said wall II along the line 6. It will be'noted that wing I2 and flap l I are integral with each other above the fold lines e and b, as shown in Fig. 5, so that both must be folded on walls I0 and II in one operation. In effect, fold line e is an extension of fold line b. The advantage of this construction will be hereinafter explained.

As clearly shown in Figs. 1, 2 and 5,a window I3 is provided in the front wall I0, near the upper edge thereof and adjacent wing l2.

My improved dual mailing envelope is formed as follows:

Starting with a cut-out blank of the type and form illustrated in Fig. 5, flap II and wing I2 are folded in unison along the lines e and 1) upon the inner faces of the rear wall II and front wall II] respectively. The free edge of wing I2 is secured to the inner face of front wall In by any suitable adhesive which is applied along the inner upper longitudinal edge of said wing I2. The main portion of the body of said wing is therefore not connected to front wall I0 save at its lower longitudinal edge. Flap I4 is then folded along line 0 on the inner face of the front wall I0. Then rear wall II is folded inwardly along the fold line a so that folded flap II will abut the upper portion of the outer face of wing l2, and the bottom edge of rear wall II will abut the outer face of flap M. In order to join rear wall II to front wall I thus forming main envelope 18, any suitable adhesive is applied between the outer face of flap II and wing l2. After the rear wall II has been secured in position, it will be noted that the two independent envelopes have been formed, namely, sup-plemental envelope or. pocket I! and main envelope l8, as clearly illustrated in Fig. 4. Supplemental envelope or pocket [1 is intended to carry first class matter, such as letters, invoices, etc., and main envelope I8 is intended to carry advertising circulars, booklets, printed matter, etc.

Sealing flap I serves as a common sealing member for both pocket I! and envelope 18. The edge of wing l2 which is adjacent sealing flap l5 may be recessed as shown in Fig. 4, so that ready access may be had to the letter in pocket IT. The letter is inserted within pocket H, so that the name of the addressee is visible through the window l3 in the front wall In.

The envelope is of sturdy construction, as shown in Pig. 3, because of the number of layers formed by flap II and wing I 2. Additional strengthening and securing means are thus provided. Furthermore, the use of flap ll provides the main envelope with additional mailing space.

Pocket i1 is formed by the wing I2 which forms the inner wall of said pocket and by a portion of the front wall ID of the main envelope which forms the outer Wall of said pocket. Main envelope I8 is formed by the walls Ill and H, wing l2, and the inner faces of flaps II and M.

It will be noted that pocket I! is shown as being parallel to the transverse axis of the envelope and is formed at one end of the envelope. I do not wish to be limited in this respect, as it is quite obvious that the supplemental envelope may be formed at either end of the envelope and may have its longitudinal axis parallel to the longitudinal axis of the main envelope if the sealing flap is located at either side of the envelope. The main portion of the inner end of pocket I! is free and is not secured to the inner face of wall In. It will be noted, however, that a portion of the inner end of pocket I! is closed in view of wing 12 being integral with flap H as shown in Figs. 1 and 2. The length of pocket I1 may be varied, but I prefer the same to be substantially equal to the width of the envelope, as illustrated in the drawings.

An examination of the blank illustrated in Fig. 5 immediately reveals the simplicity of my improvement and the economy that can be effected in the manufacture of the same.

Suitable indicia may be printed on the outer face of front wall ID if desired.

While I have shown and described a preferred embodiment of my invention, it is obvious that various modifications may be made in construction, and arrangement of parts, and in proportions, without departing from its spirit.

I claim:

1. An envelope of the character described, comprising a main envelope having a front wall and a rear wall and a closure flap therefor, a supplemental envelope formed within said main envelope, said supplemental envelope comprising an inner wall and an outer wall, the inner wall being formed from an extension of the front wall of the main envelope, a portion of the front wall of the main envelope serving as the outer wall of the supplemental envelope.

2. An envelope of the character described, comprising a first envelope having a front wall and a rear wall, a lateral extension carried by said front wall, a lateral flap carried by said rear wall, said flap and extension being integral with each other, a second envelope formed within said first envelope, said second envelope comprising an inner wall and an outer wall, the inner wall of the second envelope being formed from the lateral extension carried by the front wall, the outer wall of said second envelope being formed by a portion of the front wall of the first envelope, and a common closure member for the first and second envelopes.

3. An envelope as claimed in claim 2, in which an opening is provided in the front wall of the first envelope, said opening being located within the outer wall of the second pocket.

4. An envelope as claimed in claim 2, in which the lateral extension on the front wall of the first envelope is of greater width than the lateral flap on the rear wall of said first envelope.

5. A dual mailing envelope comprising a main enclosure having a front wall and a rear wall, a lateral wing extending from the front wall, a lateral fiap extending from the rear wall, said lateral wing and lateral flap being integral with each other, a flap extending from the side of the front wall oppositely disposed to the side from which the lateral wing extends, a pocket formed within said main enclosure, said pocket comprising an inner wall and an outer wall, the inner wall of the pocket being formed from the lateral wing on the front wall of the main enclosure, the outer wall of the pocket being formed from a portion of the front wall of the main enclosure, the outer wall of the pocket having a sight opening therein, the longitudinal axis of the pocket being perpendicular to the longitudinal axis of the main enclosure, and a common closure member for the main enclosure and pocket.
