United States Patent 3,606,138 ONE-PIECE ENVELOPE WITH INTEGRAL, DETACHABLE COUPONS CONTAINED THEREIN Robert D. Allison, West Hartford, Conn., assignor to United States Envelope Company, Springfield, Mass. Filed Aug. 21, 1969, Ser. No. 851,857 Int. Cl. B65d 27/34 US. Cl. 229-70 22 Claims ABSTRACT OF THE DISCLOSURE An en'velope enclosing a number of coupons is made from a single blank of paper or the like, which blank also includes the coupons. A potential separation line extends along each of the four edges of the finished envelope and, by tearing or cutting along these four lines, the coupons contained within the envelope are separated from one another and from the envelope. The front and rear panels of the envelope may also include coupon portions which are separated from the remainder of the envelope and from the other coupons by tearing or cutting along the potential separation lines.

BACKGROUND OF THE INVENTION This invention relates to envelopes made from folded blanks of paper or other sheet material, and deals more particularly with such envelopes particularly designed to contain other items, such as coupons, similarly made of paper or other sheet material.

The envelope of this invention is one wherein coupons or other similar items contained therein are made from the same blank of sheet material as the envelope itself, so that the envelope and the coupons may be formed simultaneously on a single machine with the machine folding the blanks so as to cause the coupons to be enclosed and sealed in the envelope. The envelope is so constructed as to allow the recipient to open it by severing it along multi ple separation lines, with this severing also serving to release a plurality of coupons or similar items which, may, for example, be redeemable special offer promotional coupons such as used in magazines, newspapers or cooperative mailings in connection with various advertising or promotional schemes, or they could be stamps or advertising slips. The envelope with its coupons, therefore, may be used to provide an economical advertising media for persons or concerns who wish to promote their own products or services without participating in cooperative type mailings, or distributions with other persons or concerns. The envelope may also be used in conjunction with a promotional game or contest of the type often used in retail merchandising, the coupons contained therein forming a part of such a game or contest, and being concealed prior to the envelope being opened.

The potential separation lines along which the various parts of the envelope are severed to open it and release its coupons are preferably lines along which the envelope blank is weakened by perforations, slits or the like so as to allow the severing to be readily accomplished by manually tering the envelope along such lines, and in the detailed description which follows the potential separation lines are described as such weakened lines. It should be understood, however, that this weakening of the potential separation lines is not essential to the broader aspects of the invention, and in some cases the weakening may be omitted and the location of the potential separation lines merely indicated by visible markings, such as printed lines or printed lines of dots, on the outer surface of the front or rear panel, or both, of the envelope with the envelope 3,606,138 Patented Sept. 20, 1971 ice SUMMARY OF THE INVENTION This invention resides in an envelope containing at least one enclosed coupon. The envelope is made of front and rear panels folded along a common fold line into overlying relationship with one another, and the coupon is formed by another panel folded along another fold line into a position between the front and rear envelope panels. The front and rear envelope panels are adhesively joined to one another along the three edges thereof other than the edge formed by the common fold line and inboard of the sealing means of each such edge is a potential separation line extending across both the front and rear panels parallel to the edge. The third panel includes a potential separation line registered with the one of the potential separation lines of the envelope panels so that by severing along the potential separation lines of the envelope panels, the envelope is both opened and the coupon portion of the third panel also separated from the front and rear panels of the envelope. The third panel preferably extends along and is integral with both the front and rear panels of the envelope and is folded along a continuation of the fold line between the envelope front and rear panels to form two overlying sub-panels each providing a coupon, and preferably a fourth panel similar to the third panel is joined to another edge of the envelope front and rear panels to provide two additional coupons. The potential separation lines may be defined by perforations, slits or other weakening means to allow severing of the envelope blank by tearing along such lines.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 show an envelope 10 embodying this invention in its finished sealed condition, and FIG. 3 shows the same envelope in an opened condition. Referring to these figures, the envelope 10 includes a front panel 12, shown in FIG. 1, and a rear panel 14 shown in FIG. 2. At its upper ends, the front panel 12 includes a sealing flap 16 which is folded relative to the remainder of the front panel 12 along an upper horizontal fold line 18 into overlying relationship to the upper marginal portion of the rear panel 14 to which it is sealed by suitable adhesive 70.

As shown in FIG. 1, the front panel 12 includes two vertical potential separation lines 20 and 22, weakened by perforations or slits, which extend thereacross with each spaced inboard a small distance from a respective one of the vertical side edges of the front panel. Likewise, two other horizontal potential separation lines 24 and 26, weakened by perforations or slits, extend across the front panel 12 with each of these lines also being spaced a small distance from a respective one of the horizontal edges of the front panel. The four weakened lines 20, 22, 24 and 26, therefore, define and surround a central portion 28 of the front panel, referred to hereinafter as a coupon portion, and also define four marginal envelope portions 30, 32, 34, and 36 each located between one of the weakened lines and the adjacent edge of the front panel.

As shown in FIG. 2, the rear panel 14 includes four similar weakened potential separation lines 38, 4t 42 and 44, registered with the corresponding weakened lines of the front panel. That is, the lines 20 and 40 are registered with one another, the lines 22 and 38 are registered with one another, the lines 24 and 42 are registered with one another, and the lines 26 and 44 are registered with one another. The four weakened lines 38, 40, 42, and 44 of the rear panel surround and define a rectangular central portion 46, referred to as a coupon portion and, also, define the marginal envelope portions 30, 32, 34 and 36.

Referring to 'FIG. 3, this figure shows the envelope as viewed from the front with the marginal portions 30, 32, 34 and 36 thereof removed therefrom by tearing along the registered weakened lines of the front and rear panels. From this figure, it will, therefore, be understood that by so removing the marginal portions of the envelope, the coupon portions 28 and 46 are separated from one another and from the remaining portions of the envelope and may be used, if desired, as individual coupons or other such items. Also, the removal of the marginal portions also separates and makes available four other coupons 48, 50, 52 and 54, located between the.

coupon portions 28 and 46 and of substantially the same size and shape as the portions 28 and 46.

The coupons 48, 50, 52 and 54 are located within the envelope 10 prior to its being opened, and the manner in which they are provided may best be understood by reference to FIGS. 4 to 7, which show the blank 56 from which the envelope and coupons are made and the manner in which the blank is folded and sealed to form a finished envelope, together with FIG. 8 which shows a cross-section through a finished envelope. Considering first FIG. 4, this figure shows the blank 56 in plan form. As shown in this figure, the blank includes the front panel 12 and rear panel 14 which are joined to one another by a common horizontal fold line 58. Connected to the left hand edge of both the front panel and the rear panel is a third panel 60 which extends along parts of both the front and rear panels and is joined thereto along another fold line 62. A similar fourth panel 64 extends along and is connected to parts of both the front panel and the rear panel along another fold line 66 at the right handedge thereof.

In making the envelope 10 from the blank 56 of FIG. 4, the third panel 60 is first folded along the fold line 62 into overlying relationship with the front and rear panels 12 and 14 as shown in FIG. 5. Next the fourth panel 64 is folded along the fold line 66 to bring it into overlying relationship with the third panel 60 as shown in FIG. 6. The front and rear panels and the third and fourth panels are then folded along the common fold line 58 to the position shown in FIG. 7. Before this is done, however, strips 68, 68 of adhesive are applied to the lower marginal portions of the flaps 60 and 64, as shown in FIG. 6, so that after the blank is folded from the FIG. 6 stage to the FIG. 7 stage, the adhesive strips 68, 68 will serve to seal the right and left hand edges of the envelope. A strip 70 of adhesive is also applied to the seal flap as shown in FIG. 6 and is used to secure the seal flap to the rear panel after the sealing flap 16 is folded along the fold lines 18 to bring it into overlapping relationship with the rear panel, the folding along the fold line 18 occurring after the stage of FIG. 7 to form. the finished envelope as shown in section in FIG. 8.

Returning to FIG. 4, it will be understood from the preceding description of the folding process that the third panel 60 is, during folding, folded along a continuation 58a of the fold line 58 and is, thereby, divided into two sub-panels 72 and 74. The sub-panels '72 and 74 each have a weakened potential separation line 76 extending thereacross which registers with the weakened lines 20 and 40 of the front and rear panels in the finished envelope. The first sub-panel 72 includes a horizontal weakened potential separation line 26a which is a continuation of the weakened line 26 of the front panel and which registers with the line 26 in the finished envelope. Likewise, the second sub-panel 74 includes a horizontal weakened potential separation line 44a comprising a continuation of the weakened line 44 of the rear .panel and which registers with the weakened line 44 in the finished en velope. The portion of the sub-panel 72 defined by the weakened line 76, the weakened line 26a, and the other two edges of the sub-panel 72 constitutes the coupon 48 of FIG. 3. Similarly, the sub-panel 74 includes the coupon 54 of FIG. 3, this coupon being defined by the weakened line 44a, and the weakened line 76, and the other two edges of the sub-panel 74.

The fourth panel 64 is generally similar to the third panel 60, and during the folding process is folded along the fold line 58b, forming a continuation of the fold line 58, to form two sub-panels 78 and 80. A vertical weakened potential separation line 82 extends across both the sub-panels 78 and 80, and in the finished envelope registers with the weakened lines 22 and 38 of the front and rear panels. A weakened potential separation line 26b, forming a continuation of the weakened line 2'6, extends lengthwise across the sub-panel 78 and another weakened potential separation line 44b, forming a continuation of the weakened line 44, extends lengthwise across the sub-panel 80. The sub-panel 78 provides the coupon of FIG. 3 and the sub-panel 80 provides the coupon 52 of FIG. 3.

In the finished envelope 10, therefore, the weakened lines 26, 44, 26a, 44a, 26b and 44b all register with one another and are severed as the lower marginal portion 36 is removed from the envelope as shown in FIG. 3. Likewise, the weakened lines 24 and 42 are registered in the finished envelope and are severed when the upper marginal portion 34 is removed from the envelope, the weakened lines 20, 40 and 76 register with one another along the left hand edge of the envelope and are severed when the left hand marginal portion 32 is removed; and the weakened lines 22, 38 and 82 registerwith one another along the rig-ht hand edge of the envelope and are severed when the right hand marginal portion 30 is removed. It should be particularly noted from FIGS. 4, 5 and 6 that the third panel is of such a length that when folded along the fold line 62, it extends beyond the weakened lines 20 and 40, 'but stops short of the weakened lines 22 and 38. Likewise, the fourth panel 64- is of such a length that when folded along the fold line 66, it extends beyond the weakened lines 22 and 38 but stops short of the weakened lines 20 and 40. Also the vertical dimension of each interior coupon 48, 50, 52 and 54 is slightly less than the spacing between the lines 24 and 26 or between the lines 44 and 42. Therefore, each of the interior coupons 48, 50, 52, and 54 are severed along only two lines of weakening during the opening of the envelope in order to separate them from one another and from the remainder of the envelope.

In the use of the envelope 10, the interior coupons 48, 50, 52 and 54 may in some cases be the only ones used as coupons, but if desired in other cases, the coupon portions 28 and 46 of the front and rear panels respectively may also be printed and used as coupons or similar items. It should also be understood that although the envelope 10 illustrated in the drawings has been shown to include four interior coupons, it could be designed to provide any lesser number of such coupons. For example, by omitting either one of the third or fourth panels, the envelope may be made to include only two interior coupons, and by using only one-half of one of the third or fourth panels, either with or without the other panel, the envelope may be made to include either one or three interior coupons. Also, it should be noted that where the portions 28 and 46 are not intended to be used as coupons the horizontal weakened registered lines 24 and 42 may be omitted as it is not necessary that the envelope be severed along these lines to release the interior coupons.
