on the back 2,
In use, a properly folded letter 14 is placed in the letter compartment 7 by inserting it through the opening of the letter compartment under the sealing flap 10 as indicated by the arrow 13 in Figure 1, and a catalogue or like matter is inserted in the envelope as indicated by the arrow 15 and the sealing flap is pasted against the closing flap 3.
The letter is now sealed as a first class piece of mail and thereafter the envelope is accessibly closed in the usual manner by folding the closing ap 3 and securing it by the fastener 5.
The back of the closed envelope as shownv inA Figure 2 appears as an usual accessibly closed envelope. The front of the envelope as shown in Figure 4 may be provided with a printed `outline 16 indicating a letter and other marks or outlines such as indicated at 17, 18, 19 and 20 for a return card, the placing of the proper postage for different classes of mail, attention calling legends and the like. 1 The front of the envelope may be provided with the usual address window 21. The printed matter on the front of theenvelope may of course be varied or partlyeliminated as one desires. t
An envelope constructed and used as hereinabove described possesses the advantage that when it is filled, the two compartment entrances are conveniently at one end and it shows ata glance through the window 11 whether a letter has been properly placed in the letter compartment before the envelope is closed. Also, the letter compartment being against the front of the envelope insures the proper placing of the address to appear in the address window 21.
The recipient cannot fail to note that there are two classes of mail within theA envelope. When the flap 3 is opened and the catalogue removed, he cannot fail to observe the letter through the window 11 and see the entrance to the letter compartment. Andas a further means of calling attention to the letter, the partition 8 may be of a, different color fromthat of the envelope. Of course, the letter may also have a striking distinguishing color to still further attract attention. l
Figure 5 illustrates a modification in which the partition 8 terminates at the folding line 22 of the envelope ap 3. In this case the partition has a cut away portion atV 23 to serve as a .window or means for exposing the letter 24.
The letter compartment is here sealed by pasting the free edge 25 of the partition 8 against the front 1 of the envelope, the edge beingl gummed to the dotted line 26 for this purpose.
Figure 6 illustrates a further modification in.
which the letter partition 8 terminates in a plurality of sealing flaps 27 and 28 between which there is a cut out 29 which serves as a letter exposing window. The flaps 27 and 28 are pasted against the flap 3 the same as in`Figure 1. They are shown perspectively. In both Figures 5 and 6 the other details of the envelopes havebeen omitted.
Figure 7 illustrates a duplex envelope which embodieslthe same advantages as the foregoing, but which in addition possessesan attention calling feature in that the envelope closing iiap with its seam is folded down on the front 1 and not The letter sealing flap is sealed on the outside of the front and appears Ain full view when the envelopeV is opened. For this :purpose the partition 30, corresponding to the parti-` tion 8, terminates in a sealing flap 31 which is slipped through a vertical slit 32 in vthe 'front 1..
The flap is gummed as at 33 and may be of less width than the partition 30. In this case the letter is inserted in the direction indicated by the arrow 34 and lies in the letter compartment 7 between the partition and the front as heretofore. Thereafter the flap 31 is folded and pasted down against the front 1 on the outside of the envelope as indicated by the dotted lines 35. The sealed letter will now appear not only in the address Window 21 but also at the corners 36 of the flap 31 as is obvious.
A catalogue is inserted in the envelope, see arrow 37, after which the ap 3 which in this case is a part of the back 2 is folded over and accessibly closed by means such as 38.
Figures 8, 9 and 10 illustrate an envelope which has the same general features and advantages described above in connection with Figures l to 6 lbesides certain other novel features of construction whereby to provide a striking appearance and calling attention to the two classes of mail in the envelope. In this instance the envelope has a front 1, a back 2 and a flap 3 as above described. The partition 41 is pasted against the front of the envelope on three sides but not at the bottom. As shown inFigure 9, the bottom 42 of the partition is not pasted at all. The one end 43 of the partition is pasted along its edge to the front, while the other end has a cut out window portion at 44 and two sealing flaps 45-46 shown only in Figure 9 whichlatter are pasted against the-'envelope flap 3 the same as in Figure 6. Entrance to the letter compartment is from the outside in the front l of the envelope. The top of the partition 41 is formed with a letter sealing iiap' 47-along the top folding edge 48 of the partition, said lap'47 being passed through a slit 49 in the envelope front from inside the envelope to the outside thereof and the top edge of the partition 41 below the flap 47 is pasted to the front of the envelope at the outside thereof as shown at 53 immediately above'the slit 49.
There is thus formed a letter compartment 7 to which entrance is gained for insertion of a letter'52 in the direction of the arrow 50 through the slit 49 which serves as the top opening of the letter compartment which latter is formed between the front of the envelope and the partitionv 41. Thereafter the letter sealing ap 47 is folded down and pasted'against the front of the envelope on the outside thereof, as shown in Figure 10. A catalogue may be inserted in the envelope in the direction of the arrow 51. In this caseof course, the sealing flaps 45 and 46 may be pasted down when the envelope is manufactured. If they are not pasted down, the letter maybe inserted at 44 as is obvious. In either case, the letter in the letter compartment is observable both in the address window and in the Window at 44. The partition 4lvis readily pasted in position after rst slipping the sealing flap 47 through the slit 49. By making the partition of a color different from that of the envelope a pleasing and striking appearance of the front of the envelope may be developed.
Referring now to Figures 11 to 13 it will be seen that the main features of the invention have been retained in a modified envelope constructionernbodying other novel features for greater efficiency in use. envelope is constructed in a manner different from the preceding ones. As seen in Figure 13 the envelope front 1 as herein dened reaches up only part way on the envelope. The back 2 isa continuation'of the front and is then bent In this case the body of the f back upon itself and behind the front 1 so to form the upper portion 55 of the front and the partition portion 8 between the front l and the back 2 behind the front l. The flap 3 is integral with the back 2, see Figure 11 and the opposite end 4 of the envelope is closed by two flaps 56 and 57 which are parts of the front 1 and partition portion 55-8.
The front 1 need not be of the same length as the portion 55 8 but may be shorter and its left edge in the drawings pasted against the-portion 55-8, which then of course will have a ilap 57 the full height of the envelope'.
The upper edge of the front 1 is pasted at 59 to the partition member 55-3 and a flap thereof 60 is bent forward and downward and pasted against the front 1 thereby providing a horizontal fold on the front of the envelope, see Figure 12. The flap 60 will appear as if it were to be opened to extract the letter, but this not being the case greater attention will be directed towards the real entrance to the letter compartment.
In addition, the front 1 is provided with the address window 21 and the partition has a sealing ap 6l, Figure 11, which seals the letter compartment 7 by being pasted down against the front 1. A letter 62 is inserted-in the compartment 7 as indicated by the arrow 63 and a caty latter is opened the recipient will at once see the sealing flap 61 of the letter compartment and also portions of the letter appearing at the corners of the ap.
Figures 14 to 16 illustrate an envelope in which the letter compartment is carried by the envelope flap 65 but nevertheless is pasted against the front of the envelope as herein defined. The front in this case serving as the envelope flap or vice versa. f
Referring to Figure li'the envelope is constructed of a flap 65--or flap forming front 1---in continuation of the back 2 which in turn is bent upwardly upon itself so to form a false front portion 66 as it might be called. K
llhe ends of the envelopes are sealed and closed by flaps 67 which may be integral with the back 2 or with the portion 66. The flap frontv 65--1 terminates in a foldable tip 68 gummed as at 69.
The letter compartment '7 is formed by pasting a partition 8 against the front in a manner to receive the letter 'l0 and vto expose it at the top and at the corners '71. The letter is inserted as indicated by the arrow 'l2 after which the letter sealing flap or tip 68 is pasted down to close the letter compartment. A catalogue may thereafter be inserted in the envelope as indicated by the arrow '73 and then the envelope front-flap closed by means as at 74, it being noted that in this case both the sealing flap 68 and the envelope flap-front 654-1 have matching apertures Y' 75 for closing purposes.
rThus there is provided an envelope having the unusual frontal `appearance seen in Figure 15 with the address appearing through the window 21 provided in the part-flap 65-1. The latter need not serve also as a sealing flap for 'the letter compartment as in Figure le, because the letter compartment may have its own sealing flap .76 as shown in Figure 16 lwhich shows said sealing iiap in its position in f ull lines before the letter is insertedand its sealed position in dotted lines.
In this instance of course the tab 68 is omitted.
From the foregoing itwill appear that in all cases the entrances to the two compartments are located at the same end or place in the envelope, except that an entrance to the letter compartment in Figure 8 is at the top thereof on the outside; also thatv entrances to both compartments are on the same side ofthe envelope so that both compartments are lled and emptied at practically one operation without turning the envelope.
It will also be observed that in all cases does the letter compartment entrance appear immediately upon opening the envelope flap 3. .Also that in all cases except Fig. '8 must the letter compartment be sealed before the envelope fiap is closed if rst class mail is placed in the letter compartment. Colored paper may be used for the partitions to distinguish them from the body of the envelope and that in some instances unusual striking appearances may be produced. It will further be understood that the closing means or fasteners for the envelope aps may be selected to suit. Printing directing matter may be placed wherever desired or necessary and other details may be added, modified or interchanged within 'u the principle of the invention and the scope of the appended claims.
It will further be understood that where in the foregoing it has been said that the three edges of the letter compartment partition were to be pasted down this need not be done. Where one edge is sufficiently close-to a fold of the envelope soas to be held by such fold the edge of the partition need not be pasted. 1
The flaps for closing the letter compartments have been shown gummed for use when a first class letter is inserted in the compartment. If Inail less than rst class is placed within the letter compartment, the sealing flaps will of course not be sealed but merely left open or tucked in to prevent the contents from falling out and the term sealing ap in the claims should be similarly understood. It should also be understood that when it is not desired to mail the letter compartment or envelope at first class postage, means mean that there is exposure in every sense of the word, as when, for instance, transparent material such as sometimes heretofore used at address windows of envelopes may be employed at the exposing means. The exposing means may be located at any suitable place in the letter compartment, whether inside or outside the closure of the main or catalogue compartment.
