Application March 1, 1939, Serial: No."2 59,179
3 Claims.
This invention relates to envelopes, particularly those of the character described in Patent No. 2,062,776, issued to me under date of December 1, .1936. Envelopes of this character are usually'used in forwarding money for the purchase of merchandise,'pa'yment of statements, and the like, so that it is desirable to enclose in the envelope a letter, order form, or a statement covering the amount being paid.
It is, therefore, a principal object of the present invention to provide a simple, inexpensive envelope equipped with a money containing .Fig. is a perspective view showing the patch pocket and a separate compartment'for reception of an enclosure.
Other objects of the invention are to provide a money compartment envelope constructed so that it may be manufactured on a standard envelope machine; to provide a money compartment envelope having a simplified sealing arrangement whereby both the money and en-' closure compartments are closed by a sealing 'flap; and to provide an envelope with a supplementary sealing flap which is adapted to be sealed with the gum of the main sealing flap to close the money compartment and folded with the mainflap when it is brought into sealing relation with the back of the envelope.
In accomplishing these and other objects of the invention, as hereinafter pointed out, 'I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:
Fig. 1 is a perspectiveview of an envelope on the line 6-6 of Fig. 1.
Fig. I-is a perspective view of a modified form of envelope wherein the supplementary sealing flap is omitted.
Fig. 8 is a perspective view of an ordinary envelope blank which maybe used in producing a further modification of the invention.
Fig. .9 is a perspective view of a patch consistdow envelope.
ing of a section of gum tapeto be applied to the inner face of the blank illustrated in Fig. 8 to form the money compartment.
applied to the blank and the blank partly folded.
Fig. 11 is a perspective view of the complete envelope showing the sealing flap portion of the tape in sealed relation with the gummed closure fiap'of the envelope. I
Fig. 12 is a perspective view of the envelope after the flaps hav been severed, as when opening the sealed envelope.
' Fig. 13 is a cross-section through the envelope with the closure flap in sealed position.
Referring more in detail to the drawings:
l designates an envelope blank, including a front portion 2 of substantially rectangular shape, side flaps 3 and 4' projecting from the sides of the front portion, a main sealing flap 5, and a back flap 6 projecting from the upper and lower edges of the front portion, as clearly shown in Fig. 2. The upper edge of the back flap 6 may be provided with a supplementary sealing flap 'l of less length and Width than the flap 5. c
The back flap 6 is substantially the same width and depth as the front portion 2 but the side edges 8 and 9 converge slightly toward the edge thereof which carries the supplementary sealing flap I.
The sid flaps 3 and 4 extend the full depth ofthefront portion and are of a width to provide ample sealing area for the back flap 6 in forming an enclosure compartment, as later described. p
The main sealing flap 5 extends completely across the width of the front portion 2 and is preferably of a depth" to provide more than the ordinary sealing surface In. The supplementary sealing flap 1 is of narrower width and less depth so that when the blank is folded the terminal edge! I thereof will be spaced below the terminal edge l2 of the mainflap, as clearly shown in Fig. 4.
shapes and sizes but preferably consists of a rectangular strip of less width than the width of the envelope and of shallower depth so that.
The patch l3 'may be of variousthe side edges M and I5, and bottom edge is are spaced inwardly from the corresponding edges of the front portion 2 and are sealed thereto by strips of adhesive l1, l8 and I9 illustrated in Figure 2, the patch being applied so that the upper edge 20 is located in registry with the upper edge of the front portion to form an insert opening 2| therebetween, as shown in Fig. 3.
After application of the patch, the blank passes through the section of the machine which applies sealing gum 22 to the inner face of the main sealing flap 5. The sealing gum extends from the terminal edge l2 completely across the width of the flap, but is spaced slightly from the insert opening 2|, as illustrated at 23. The sealing gum, however, is carried completely to the fold portion near the ends of the sealing flap so that tight seals are effected at the corners of the envelope.
The blanks, after passing through the drying section of a standard machine, then have their side flaps 3 and 4 folded over the inner face of the front portion 2 on fold lines 24 and 25, after which gum stripes 26 and 2'! are applied thereto and the back flap 6 is folded thereover into sealing relation with the gum stripes on the fold line 23 to form an enclosure compartment 29 having I an insert opening 30 extending across the entire width of the envelope. Folding of the envelope is then complete with the supplementary sealing flap 1 overlapping the gum 22 on the main sealing flap. The terminal edge I I, however, is spaced below the terminal edge l2 of the main flap so as to expose a portion of the gum therebetween, as indicated at 3| in Fig. 4.
The form of the invention shown in Fig. 7 is exactly the same as that just described, with the exception that the supplementary sealing flap 1 is omitted.
In using the preferred form of envelope constructed as described, the money to be enclosed, such as coin, currency or the like, is inserted through the opening 2| into the money pocket, after which the enclosure, such as a statement, order blank, or the like, is inserted in the enclosure compartment through the opening 30 so that the enclosure lies between the back flap and the money pocket forming patch. The supplementary flap is raised from the main flap so that the gum may be moistened completely across the width thereof. The supplemental flap is then pressed against the moistened gum of the main flap. The main sealing flap is then folded on the fold line 32, together with the adhered supplementary flap, which folds on the line 33 into sealing relation with the outer face of the back flap, as shown in Fig. 6. The gummed area 3| between the terminal edges of the respective flaps effects seal of the main flap along the entire length thereof so that it is sealed to the back flap even though the supplementary flap is positioned thereunder.
When the envelop is received by the addressee, a letter opener may be inserted in one corner of the envelope under the main sealing flap and drawn along the folds of the sealing flap to effect severance thereof, including the supplementary flap, as shown in Fig. 5, so that both pockets are exposed for removal of the contents.
The form of the invention illustrated in Fig. 7 operates in the same manner, with the exception that the closure flap seals both the money and pocket may be applied to the inner face of the back flap without departing from the spirit of the invention.
Figs. 8 to 13 inclusive show an embodiment of the invention carried out in a standard type envelope. In this form the envelope blank 35 is of conventional design having a rectangular portion to form the front of a completed envelope, substantially angular shaped end flaps 31 and 38, and a back flap 39 which is adapted to be sealed to the end flaps by gum, as indicated at 40 in Fig. 10, to form the back of the envelope. The body portion of the blank has a sealing flap 4| that is adapted to be folded over the back portion and sealed thereto with gum 42. In this embodiment of the invention, the patch is formed from a section of gum tape 43 having dimensions corresponding to the desired pocket. The side and bottom marginal edges of the gummed surface are moistened in the course of envelope manufacture, as indicated at 44 and 45, and the patch is applied to the inner face of the body portion of the blank with the upper edge thereof extending above the fold line 46 of the sealing flap 4| to leave a loose, marginal, upper edge on the patch to constitute a sealing flap 4'! for the coin pocket. After the envelope is completely formed, it appears as shown in Fig. 11. In sealing an enclosure in the money compartment, the gum on the flap 4? is moistened and sealed to the sealing flap 4| of the envelope, after which an enclosure to be placed in the envelope is inserted and the gum on the flap 4| is moistened and the flap is folded together with the coin compartment flap 4'? over the back portion of the envelope, as shown in Fig. 13. When the envelope is opened, the paper knife or the like severing the sealing flap 4| also severs the flap 41 of the coin pocket so that the coin pocket is simultaneously opened as shown in Fig. 12.
From the foregoing it is obvious that I have provided a money compartment envelope which may be readily manufactured on a standard envelope machine and which includes an enclosure compartment so that a letter, statement, order,
' or the like, may be included in the envelope along with the money enclosure, but in a separate compartment.
What I claim and desire to secure by Letters Patent is:
1. A money compartment envelope including front and back portions, side flaps on one of said portions and sealingly engaging the other portion to form an enclosure compartment having an insert opening extending along one edge thereof, a money pocket forming patch having side and bottom edges spaced from corresponding edges of the envelope and secured to the inner face of one of said portions with its upper edge substantially registering with said enclosure compartment insert opening and providing an insert opening to said money pocket, a flap for said money pocket, and a gummed sealing flap on one of said portions and foldable with said pocket flap to sealingly engage with the other of said portions and retain the pocket flap sealed between said portion and'the sealing flap.
2. A money compartment envelope including front and back portions, side flaps on one of said portions and sealingly engaging the other portion to form an enclosure compartment having an insert opening extending along one edge thereof, a money pocket forming patch having side and bottom edges spaced from corresponding edges of the envelope and secured to the inner face of one of said portions with its upper edge sub-- partment insert opening to form an insert opening into said pocket, a gummed main sealing flap on one of said portions, and a supplemental sealing flap extending along the insert opening of said money pocket and of a size to overlie the gummed area of the main sealing flap so that said-supplemental sealing flap seals against the gum of the main sealing flap when the gum is moistened and is foldable with the main sealing flap when the main sealing flap is sealed with said other portion, the marginal edges of said supplemental flap terminating Within said gummed area so that the gum securing the main sealing flap forms an extended seal about said edges of the supplemental flap.
3. A money compartment envelope including front and back portions, side flaps on one of said portions and sealingly engaging the other portion to form an enclosure compartment having an insert opening extending along one edge thereof, a money pocket forming patch having side and bottom edges spaced from corresponding edges of the envelope and secured to the inner face of one of said portions with its upper edge substantially registering with said enclosure compartment insert opening to form an insert opening into said pocket, a gummed main sealing flap on one of said portions, and a supplemental sealing flap projecting from the conespending edge of the other portion to overlie the
