Description
This invention relates generally to an envelope assembly, and more particularly to such an assembly of interconnected sealed envelopes having return envelopes with a connected flap contained therein which, after extraction, avoids accidental removal of the connected flap.
In the corresponding assembly of interconnected sealed envelopes of the type disclosed by U.S. Pat. No. 3,554,438, commonly owned herewith, insert material comprising a top opening return mailer envelope is shown in FIGS. 17 and 18 thereof. Top and back panels 54x and 55x are secured together along three sides and a top glue flap on the back panel is folded over and secured to the front face of the top panel upon extraction of the return mailer after waste chip 54e is removed and discarded. One of the problems with such an assembly is that many recipients of this type return mailer, upon extraction thereof, tend to remove not only the waste chip but also the rewettable glue flap. The return envelope is therefore left unsealable.
This problem is substantially eliminated by the present invention. The return mailer envelope is connected to a portion of the sealed envelope by means of this waste chip so that, upon extraction of the insert material, the waste chip is retained within the sealed envelope eliminating the need for subsequently removing same before top sealing of the return mailer as heretofore required. This is an object of the present invention.
Another object is to provide an envelope assembly of interconnected sealed envelopes each having insert material therein in the form of a return mailer envelope having an opening along one edge, with one of the upper or lower panels of the return envelope having a sealable flap for closing over the other panel, a separable portion on this other panel serving to connect the return mailer with the sealed envelope, and being retained with the sealed envelope upon extraction of the insert.
A further object of this invention is to provide such an envelope assembly wherein the insert material extends into a removable tear strip provided along one edge of the envelope, the envelope opening lying perpendicular to such edge so that the return mailer envelope is separated from the aforementioned portion along a line parallel to the direction of extraction.
A still further object of the invention is to provide an alternative envelope assembly of interconnected sealed envelopes each having insert material therein in the form of an insert sheet and a return mailer envelope having an opening along one edge, one of the panels of the return envelope having a sealable flap for closing over the other panel, a separable portion of this other panel serving to connect the return mailer with the adjacent insert sheet so that such portion remains connected with the insert when separated.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the invention when taken in conjunction with the accompanying drawings wherein:
FIG. 1 is a fragmentary perspective view, on a slightly reduced scale, of an envelope assembly of interconnected sealed envelopes in accordance with the invention;
FIG. 2 is a plan view of one embodiment of an envelope of FIG. 1 shown partly broken away;
FIG. 3 is a plan view similar to FIG. 2 with the insert material contained within the envelope shown fully extracted therefrom;
FIG. 4 is a perspective showing of the return mailer extracted from the FIG. 2 envelope;
FIG. 5 is an expanded sectional view of the sealed envelope containing the return mailer taken along line 5--5 of FIG. 2;
FIG. 6 is a view similar to FIG. 5 showing the process of extracting the return mailer insert;
FIG. 7 is an expanded sectional view of the sealed envelope and its return mailer insert taken along line 7--7 of FIG. 2;
FIG. 8 is a view similar to FIG. 7 showing another embodiment of a sealed envelope according to the invention; and
FIG. 9 is a view similar to FIG. 5 of the other embodiment.
Turning now to the drawings wherein like reference characters refer to like and corresponding parts throughout the several views, an envelope assembly is generally shown at 10 in FIG. 1 as comprising a plurality of sealed envelopes 11 interconnected in succession along transverse tear lines 12. Feed holes 13 are provided along opposite sides of the assembly which is customary for feeding the assembly through a high speed printer, and through other web operations.
Each envelope comprises front and back panels 14 and 15, as shown in FIGS. 5-7, secured directly together along opposite ends by means of some suitable glue as at 16, 17. Each envelope contains insert material including a return mailer 18 as shown in FIG. 4. This insert comprises lower and upper panels 19 and 21 (FIG. 7) each divided into sections 22, 23 and 24, 25. As shown in FIG. 4, sections 22 and 24 are interconnected along a substantially U-shaped pattern paste configuration 26 so that the upper edges thereof are open as at 30. Portions 23 and 25 of respective panels 19 and 21 shown in FIG. 7 are of the same size and are superimposed over one another, with sections 22 and 23 being interconnected along a fold line 27. Sections 24 and 25 of panel 21 are interconnected along a tear line 28.
This return mailer envelope is connected by means of its chip or section 25 to one of the envelope panels as, for example, 15 shown in FIG. 7 with the use of adhesive 29. This may be spots or strips or pattern paste which is used in securing the mailer in place. As will be seen hereinafter, section 23 becomes a return envelope flap for sealing the mailer after extraction.
One side edge of panels 19 and 21 are secured together and to the front and back panels of the envelope by means of adhesive 31 (see FIG. 5). Weak tear lines having very keen ties are provided as at 32 for each of the return envelope panels 19 and 21.
As also seen in FIG. 5, the opposite sides of the return mailer panels are connected together and to the envelope front and back panels 14 and 15 by means of adhesive 33. Keen tear lines 34 having weak ties are likewise provided in panels 19 and 21 between adhesive patterns 26 and 33 so as to delimit that side end of the return mailer.
A tear strip 35 is provided for the envelope as defined by tear lines 36 provided in front and back panels 14 and 15 of the envelope. A thumb tab 37 extends inwardly of these tear lines to facilitate easier extraction of the insert.
After each sealed envelope 11 is burst from assembly 10 and thereafter mailed out, the recipient opens and extracts the return mailer by following instructions to grasp tear strip 35 with one hand over the thumb tabs, the other hand being placed outwardly of tear lines 32 in much the same manner as that described in the aforementioned patent. With a snapping action in a direction of the arrows of FIG. 3, return mailer 18 is extracted from the envelope as the connecting ties are broken along tear line 28. The keen ties at opposite sides of the return mailer are easily broken during the extraction process, tear strip 35 therefore being easily separated from the mailer. And, since the indicia imprinted on each envelope extends between opposite feed holes 13, opening 30 is parallel to such indicia and therefore defines a top opening. The waste chip or portion 25 of the return mailer construction is retained with the envelope after extraction so that the recipient is not required to remove this waste chip after extraction of the return mailer as before. With such a construction, the recipient then merely folds flap 23 down over the outer surface of section 24 after adhesive strip 38 is rewetted.
In addition to a return mailer, the sealed envelope of the FIGS. 2-7 embodiment may contain one or more insert sheets 41 as shown in FIG. 9 connected to the envelope along at least one end thereof by a line 42 of perforations. End 43 of the insert may be spaced inwardly of adhesive strip 33 which interconnects panel 21 of the return envelope 18 with envelope panel 14. During the extraction process, similarly as in FIG. 6, both the insert sheet and the return mailer envelope are extracted together whereafter the insert sheet may be stuffed within the return envelope before mailing.
In the other embodiment of the invention, the return mailer is connected to insert sheet 41 rather than to one of the sealed envelope plies. As shown in FIG. 8, sections 22 and 23 are interconnected along fold line 27, and sections 24 and 25 are interconnected along tear line 28. The waste chip or section 25 connects the return mailer with insert 41 by means of adhesive 29. Otherwise, the envelope assembly construction of FIG. 8 is the same as in the first embodiment.
Extraction of insert 41 and the return mailer is the same as that shown in FIG. 6 with the addition of an insert sheet therein. However, waste chip 25 is removed along with the insert material upon extraction, rather than being retained with the sealed envelope as before. Insert sheet 41 is then merely separated from return mailer 18 along line 28, and is stuffed therewithin or retained by the recipient as the forms system design requires.
From the foregoing, it can be seen that a simple and economical yet highly effective return mailer has been devised wherein its waste chip normally provided in such constructions is retained either with the sealed envelope or with an insert sheet upon extraction thereof. Any accidental removal of flap 23 along with the waste chip is therefore avoided since the return mailer is either fully in a condition for mailing immediately upon its extraction without the need for removal of any portion thereof, or is readied for return mailing by simply separating it from its connected insert sheet.
Obviously, many modifications and variations of the invention are made possible in the light of the above teachings as, for example, a top or bottom opening return mailer. It is therefore to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
