ENVELOPE

Abstract: The present invention is concerned with An article constituting an envelope in which an insert is nested comprising a sheet (10) of material having given horizontal and vertical dimensions, the sheet having a first fold line (26) parallel to and between the horizontal end edges thereby providing first and second parts of the sheet and a second fold line (82) perpendicular to the first fold line, a window in one of the parts of the sheet, and lines of adhesive on the sheet along portions of the edges thereof, the arrangement being such that the first part of the sheet may be folded along the first fold line (26) to overlie the second part of the sheet and then the overlaid parts of the sheet folded again along the second fold line (82) to provide a compartment of the envelope in which the insert is to be nested whereby the insert (83) is prevented by the second fold from moving to the window (56) and obscuring the view of an address through the window (56).

Description: SUMMARY AND OBJECTS OF INVENTION This invention pertains to envelopes. It is now quite common for envelopes to be manufactured in automatic equipment, including means for so-called variable printing of names, addresses and the like under computer control. Many of these are envelopes in which a window is provided for viewing the outgoing address which has been printed on an underlying panel in an area designed to be within the confines of the window. The envelopes are also designed to have inserts included therein, but inserts have created problems by moving into the address area and obscuring the view thereof through the window. It is an object of this invention to provide an envelope in which an insert may be nested so that the insert will not be able to cover a window through which an address is intended to be viewed. It is also an object of this invention to provide an outgoing envelope which contains a top opening return envelope, into which a nested document may be placed. It is a further object to provide means to seal the return envelope. According to the present invention an article constituting an envelope in which an insert is nested comprises a sheet of material having given horizontal and vertical dimensions, the sheet having a first fold line parallel to and between the horizontal end edges thereby providing first and second parts of the sheet and a second fold line perpendicular to the first fold line, a window in one of the parts of the sheet, and lines of adhesive on the sheet along portions of the edges thereof, the arrangement being such that the first part of the sheet may be folded along the first fold line to overlie the second part of the sheet and then the overlaid parts of the sheet folded again along the second fold line to provide a compartment of the envelope in which the insert is to be nested whereby the insert is prevented by the second fold from moving to the window and obscuring the view of an address through the window. THE DRAWINGS Embodiments of envelopes in accordance with the present invention will now be described by way of example with reference to the accompanying drawings wherein :- FIGURE 1, pertaining to a first embodiment, is a plan view of a first sheet from which the envelope is made, with an overlaid second sheet and a strip of removable protective material. FIGURE 2 is a plan view of the sheet of FIGURE 1 but turned over top-to-bottom. FIGURE 3 is a view as in FIGURE 1 but with the right-hand side as shown in FIGURE 1 folded over a portion of the left-hand side of FIGURE 1. FIGURE 4 is a view of the configuration of FIGURE 3 after being folded downward from the top along a horizontal fold line midway of the height of the article as shown in FIGURE 3. FIGURE 5 is a view of the illustrative embodiment of FIGURES 1-4 after it has been opened and ready for removal and use of the return envelope. FIGURE 6 pertains to a second embodiment, this being a plan view of a sheet from which the mailing piece is made. FIGURE 7 is a plan view of the sheet of FIGURE 6 but turned over top-to-bottom. DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS In the first embodiment a first sheet 10 extends horizontally from left edge 12 to right edge 14 and vertically from top edge 16 to bottom edge 18. Marginal strips 20 and 22 may originally be in place along edges 12 and 14, each provided with tractor holes 24, to facilitate manufacture in customary printing and adhesive applicator machinery (not shown) and to facilitate continuous feeding through computer out-put printers. Approximately two-thirds of the distance from edge 12 a vertical fold line 26 is provided, which may be perfo rated to facilitate folding at this point. A perforated line of weakening 28 is provided to the left of line 26, and another perforated line of weakening 30 to the right of line 26. Immediately to the right of line 30 a removable protective strip 32 is provided, which overlies a line of reusable adhesive 34. A second sheet 36 overlies the right-hand area of sheet 10, between the protective strip 32 and edge 14, being permanently held to sheet 10 by lines of permanent type adhesive 38, 40, 42, 44, 46 and 48. Still referring to FIGURE 1, lines of heat settable adhesive are available for use as the sheet 10 is folded as explained below: these lines are 50, 52 and 54, running about the left-hand area of sheet 10. A window 56 is provided in the left area of sheet 10, positioned to align with an area 58 on the sheet 36 within which variable name and address information may be printed. At the appropriate time after computer printing, and before sealing (see below), the marginal tractor hole strips may be sliced off along lines 60 and 62. Now referring to FIGURE 2, this shows the article of FIGURE 1 turned over top-to-bottom. Here like features previously mentioned in FIGURE 1 are correspondingly numbered. Additionally, heat settable adhesive lines 64, 66 and 68 are provided. Also, areas of what will become the front of the return envelope are shown: return address area 70, destination address area 72 and an area for postage 74. Referring to both FIGURES 1 and 2, further perforated lines of weakening 76, 78 and 80 are provided, for a purpose described below. FIGURE 3 shows the article of FIGURES 1 and 2 after the right-hand area of FIGURE 1 has been folded over the left-hand area along fold line 26. FIGURE 4 shows the article of FIGURE 3 after the upper area of FIGURE 3 has been folded down over the lower area along a fold line shown as 82 in FIGURE 3. This fold now brings the window 56 into place to show the original addressee's address in the usual place on what is now an outgoing envelope ready for mailing -- the heat settable adhesive lines having been heat set after the computer printing process. It will be observed from the foregoing description that an insert indicated by chain line 83 placed below the line 82 will be captured by the fold 82 and therefore will be unable, after the folding step about line 82, to move to and obscure the view of the address area 58 through the window 56. The recipient of the outgoing envelope (FIGURE 4) may now open it as follows: tearing off the right marginal strip along perforated line 28 (and aligned perforated line underneath); tearing off the bottom marginal strip along perforated line 76 (and aligned perforated lines underneath), and tearing along perforated line 80 (with an aligned length of line 80 underneath). The thusly opened envelope may then be laid out as shown in FIGURE 5. At this point the return envelope may be separated from the rest of the article along perforation line 26. Any desired insert may then be placed in the return envelope, the protective strip 32 peeled off, and the reusable adhesive strip 34 folded over as the closure flap of the return envelope. The latter is then ready for mailing to the address shown on the front of the return envelope (area 72 in FIGURE 2). The embodiment of FIGURES 15 may be modified with respect to the adhesive 34. Instead of employing a reusable adhesive a rewettable glue or a pressure seal adhesive may be used. The protective strip 32 would not be required with the rewettable adhesive, but would be preferred for use with the pressure seal adhesive. Another embodiment of the invention is shown in FIGURES 6 and 7. This embodiment includes the basic features of the first embodiment, except that the return envelope is dispensed with. Corresponding features are marked with the same reference characters, except followed by the letter ª. In FIGURES 6 and 7 vertical fold line 26a and horizontal fold line 82a are provided, along with perforated lines 28a and 30a. An address may be printed in area 58a to show through window 56a when the sheet 10a is folded along line 26a. Then, as the case with the first embodiment, a second fold along line 82a provides an outgoing envelope. Lines of glue 84 and 86 (FIGURE 6) may be provided on the top side of sheet 10a and lines of glue 88 and 90 (FIGURE 7) may be provided on the reverse side of sheet 10a to affix the parts together to form the final envelope. Again, as in the first embodiment, an insert 83a placed in the envelope below the fold line 82a (as viewed in FIGURE 6) will not be able to move to and obscure the view of the address area 58a through the window 56a. The recipient of the outgoing envelope of FIGURES 6 and 7 may then open it following the procedure described above for the first embodiment.
