Abstract
A one piece mailer for use in laser printers or xerographic copying machines includes a standard size sheet which may be employed in laser printers or xerographic machines without special handling equipment and involves printing on one side only of the mailer. In addition, stable adhesive material is employed for sealing the one piece mailer which will not run or contaminate the office machines, when it is subject to several hundred degrees heat. This adhesive is preferably a water-activated adhesive other than natural gum (which is heat-activated). The first embodiment of the invention includes a mailing sheet having an upper and lower half, with the upper half carrying the addresses and the message, and the lower half having windows which match the location of the addresses on the upper half of the mailer. The second embodiment of the invention involves a mailer having a first full sheet having an upper portion on which the messages are printed, and a lower portion on which the addresses are printed. On the rear side of the main sheet is a short partial sheet toward the bottom of the main sheet forming an envelope, and with a transverse strip of adhesive immediately above the envelope pocket to seal the envelope. Perforations extend across the main sheet just above the adhesive-coated strip, so that the message section may be separated from the envelope portion, and the message portion folded and placed within the envelope, and the envelope sealed.

Description
Field of the Invention
This invention relates to one piece mailers for use under adverse heat and moisture conditions.
Background of the Invention
Laser printers are becoming more widely used in business correspondence, in combination with computer terminals. One serious disadvantage of laser printers, however, is that it is not easy to address envelopes. Accordingly, many offices must necessarily have both available typewriters for addressing envelopes. To avoid this problem, it would be convenient to use one piece mailers in which the address and the message were both printed onto the one piece mailer by the laser printer. However, one piece mailers normally have natural gum adhesive for closing the mailer and forming it into an envelope. Unfortunately, this type of natural gum adhesive is heat-activated and will contaminate the operative mechanisms of many laser printers or xerographic copiers.
Accordingly, a principal object of the present invention is to overcome the problems outlined hereinabove.
Summary of the Invention
In accordance with one embodiment of the invention, a one piece mailer is formed of a single sheet of paper, which may for example, be 81/2 inches by 11 inches, or up to 81/2 by 14 inches in length, and the addresses and message are typed on the upper one-half of the sheet, which is a continuous, single thickness sheet. The lower half of the sheet is provided with two windows, so that when the sheet is folded in half, the addresses from the upper portion of the sheet are visible through the windows. Incidentally, the upper portion of the sheet includes defined areas or boxes where the name and address of the sender and the addressee are to be located, so that they match the positioning of the windows in the lower half of the sheet. In addition, the lower edge of the lower half of the sheet is provided with a strip of stable, moisture or water-activated adhesive to permit sealing of the one piece mailer to form an envelope, when the mailer is folded in two. The two sides of the lower half of the mailer may also be provided with a stable, water-activated adhesive for completely sealing the envelope.
It is important that the water-activated adhesive not be conventional "natural" gum, as this type of adhesive becomes sticky with the few hundred degrees of heat encountered in a laser printer of xerographic machine, and the sticky, heated natural gum would then contaminate these office machines.
Instead of a stable, water-activated adhesive similar to a gum, the adhesive along the edge or edges of the lower half of the sheet may be a stable, pressure-sensitive adhesive covered with the usual strip of release coated protective paper so that, when it is desired to close the envelope, the strip of protective paper is removed and the mailer is folded up. The pressure-sensitive adhesive must be of a type which will not flow under a temperature of a few hundred degrees, and may be spaced slightly back from the edges of the area where it is to be located.
In accordance with another embodiment of the invention, the mailer may be formed of one full sheet of paper of the sizes mentioned hereinabove, with the printing to be applied on a front side of the sheet, and no printing on the back side thereof. In addition, on the lower end or portion of the imprinted back side of the sheet, an additional partial sheet of paper is provided and secured to the main upper sheet to form an envelope. Further, a strip of adhesive extends along the top of the partial sheet, with perforations immediately above the strip of adhesive. A letter would then be printed on the upper portion of the front of the main sheet of the mailer, and at the same time, addresses would be printed onto the envelope portion of the mailer, on the lower part of the front side thereof. Following printing, the message portion of the mailer would be separated from the envelope along the perforations, folded up, and inserted into the envelope, and sealed. Again, the adhesives employed would be of the stable types discussed hereinabove, which would not contaminate the laser printer or xerographic copying machines.
It may be noted that in both embodiments of the invention as discussed hereinabove, the leading or top half of the mailer is only a single continuous sheet of paper, and includes no windows or adhesive material. In this regard, it has been determined that the presence of windows or other significant irregularities in the leading edge of the mailer will tend toward jamming the office machines. It may also be noted that in both embodiments of the invention, only one side of the mailer is printed, and the other side of the mailer needs no printing. Accordingly, the mailer is only processed through the laser printer or the copier machine once.
Other ojects, features, and advantages of the invention will become apparent from a consideration of the following detailed description and from the accompanying drawings.

Detailed Description
Referring more particularly to the drawings, FIG. 1 shows a one piece mailer 12 for use with laser printers or xerographic copying machines. The one piece mailer includes marked areas or boxes 14 and 16 for printing the sender's name and address, and that of the addressee, respectively. In addition, windows 18 and 20 are provided, so that, when the one piece mailer 12 is folded about its horizontal center line indicated by dashed lines 22, the addresses of the sender and the addressee appear through the windows, as indicated in FIG. 2. More specifically, with reference to FIG. 2 it may be noted that the sender's name and address from the block 14 in FIG. 1 appears through the window 18, and the addressee's name and address from the area 16 of FIG. 1 appears in the window 20.
Now, returning to FIG. 1, the outer periphery of the mailer 12 may be perforated along the lines 26 for ease in opening the one piece mailer following receipt.
The lower edge of the mailer 28 is coated with a stable, water-activated, or moisture-activated adhesive which is not significantly affected by either hear or exposure to high humidity. In this regard, it is noted that so-called "natural" gum adhesives are not suitable for this purpose, as the relatively high heat of a few hundred degrees to which the paper is subject in a laser printer or by the hot rollers of a xerographic copying machine, will produce contamination to the printer or copier from adhesives such as natural gum. There are known adhesives which are moisture activated and are relatively stable in that they are not activated by temperatures of a few hundred degrees, or relatively high humidity conditions. One such adhesive is available from Adhesives Consultants Corporation, 25817 Clawiter Road, Hayward, Calif. 94545, under the trade name "Adcon FS-6". This adhesive is a polyvinyl emulsion. As noted above, other stable moisture-activated adhesives are known, and such other adhesives may be employed.
If desired, the side areas 30 and 32 may also be coated with the same type of moisture-activated adhesive, so that the mailer is more securely held together. As mentioned above, with reference to FIG. 2, when it is desired to open the mailer, the strips along the edge of the mailer may be ripped off along the perforations 26.
Referring now to FIGS. 3 and 4 of the drawings, the two sides of another form of mailer 32 for use with laser printers is shown. The mailer of FIGS. 3 and 4 is divided into two areas by the transverse perforations 34. The upper portion 36 of the mailer is reserved for typing a letter or other communication to the addressee, and the lower portion 38 forms the front of an envelope, carrying the addresses of the sender at area 40, and of the addressee in area 42.
As may be seen in FIG. 4, showing the unprinted reverse side of the mailer, the lower section of the mailer is of double thickness, with an additional layer or partial sheet of paper 44 being permanently secured along three edges 46 to the back side of the lower section 38 of the sheet shown in FIG. 3. A strip of stable, water-activated adhesive 48 extends across the sheet 36 between the upper edge of the partial sheet 44, and the perforation line 34. Accordingly, when the letter or other communication has been printed, it may be removed from the envelope along the perforation line 34, folded, and inserted into the envelope formed by the lower portion of the mailer. The adhesive 48 is then moistened, and folded over to seal the envelope.
Incidentally, it may be noted that in both the case of the embodiment of FIGS. 1 and 2, and that of FIGS. 3 and 4, the laser printer or copier only prints on one side of the mailer. In addition, the leading edge of the mailer in both cases is a smooth single thickness leading edge of the sheet forming the upper portion of the mailer; and the windows in the case of FIGS. 1 and 2 or the double thickness in the case of FIGS. 3 and 4, and adhesive material, are on the trailing portion of the sheet as it passes through the laser printer or the copying machine, so that the possibility of jamming or malfunction of the laser printer or copier is minimized. Incidentally, in that regard, it has been found that, if windows are formed in the leading edge of material to be fed through a laser printer or copier, the probability of jamming is significantly increased.
FIG. 5 is a partial cross-sectional view taken along lines V--V of FIG. 4. It may also be noted that, in FIG. 5, the thickness of the layers of paper 36, 38 and 44 is exaggerated, as is the thickness of the permanent adhesive material 52 which extends around to partially close the envelope. The stable, moisture-activated adhesive strip 54 is also shown in FIG. 5 with an exaggerated thickness.
FIG. 6 shows a slight modification as compared with the arrangement shown in FIG. 5. More specifically, instead of the stable moisture activated adhesive 54 as shown in FIG. 5, the embodiment of FIG. 6 discloses the use of a permanent, pressure-sensitive adhesive 62, covered by a thin strip of tape 64 which in turn has been coated by a release material such as silicone, on its inner surface so that it may be easily removed from the permanent, pressure-sensitive adhesive strip 62. It is also noted that the pressure-sensitive adhesive is preferably spaced back from the edge of the overlying strip by a millimeter or two of space, to avoid the possibility of flow of the pressure-sensitive adhesive is preferably spaced back from the edge of the overlying strip by a millimeter or two of space, to avoid the possibility of flow of the pressure-sensitive material when subject to heat. Following removal of the strip 64 and the separation of the envelope at the perforations 34, the flap is folded down over the outer partial sheet 44 to seal the envelope.
In the arrangement of FIG. 1, it was disclosed that the gummed areas 28, 30, and 32 would engage the printed side of the upper portion of the mailer 12. An alternative arrangement is shown in FIG. 7 which shows the slightly modified mailer 12' being provided with the strip 28' folded over the upper edge of the mailer 12 with the inner strip of stable moisture activated adhesive being indicated at reference numeral 72 if FIG. 7 of the drawings. Of course, with the arrangement as shown in FIG. 7, a slight shifting of the relative positions of the windows and the zones in which the addresses appear, would be accomplished, and the line along which the strip 28' is to be folded would be slightly scored or perforated to facilitate folding.
Concerning the dimensions of the one piece mailers, it is clear that standard size envelopes are too small for handling by laser printers. Standard size paper such as 81/2 by 11 inches, to 81/2 by 14 and 81/2 by 17 inches can definitely be used. In addition, somewhat larger paper such as 11 by 17 inch paper may be used in larger types of laser printers; and paper as short as 81/2 inches wide by 6 inches long may be handled in standard laser printers.
In conclusion, it is to be understood that the foregoing detailed description and the accompanying drawings illustrate the preferred embodiments of the invention. However, various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, by way of example and not of limitation, the stable, moisture-activated adhesive may be replaced by stable, pressure-sensitive material shielded by appropriate protective strips in each case. In addition, other forms of mailing arrangements wherein only one side of the sheet need be printed, and including the address and message on a single side of the sheet, may be employed. Accordingly, the present invention is not limited to the embodiments shown in the drawings or described in detail hereinabove.
