Definitions

  • This invention relates generally to a self- sealed envelope assembly having a free insert therein, and more particularly to such an assembly wherein the insert is immobilized in place by means of self-adhering material at least partially securing the envelope plies together and in contact with the insert.
  • U.S. Patent Specification No 4,010,889 commonly owned herewith discloses a free insert immobilized in place within the outer envelope plies by means of retention chips bearing against opposed side and end edges of the insert.
  • U.S. Patent Specification No 3,777,971 discloses a free insert being held in place within a stuffed sealed envelope by means of embossments struck from one of the outer envelope plies and presenting shoulders abutting against'edges of the insert.
  • a free insert is immobilized within a stuffed sealed envelope by means of adhesive used in securing the outer envelope plies together.
  • Another object of the invention is to provide such a stuffed sealed envelope assembly capable of being manufactured quickly and economically as the inserts are placed in contact with the means securing the outer envelope plies together yet remain unattached to such means as to provide a snug peripheral embrace of the insert and at the same time insure easy extraction without interference.
  • an assembly of stuffed sealed envelopes comprising superimposed upper, intermediate and lower continuous plies 11, 18, 12 respectively defining envelope fronts, inserts and envelope backs delimited by spaced cross lines 13 of weakening in said plies and means in said fronts and backs for opening the sealed envelopes and extracting said insert, said inserts being wholly unsecured to said upper and lower plies, a first opposed pair of free marginal edges lying along opposite sides of each of said cross lines, first and second sealing portions respectively on said supper and lower plies in confronting relationship and lying along said cross lines, said portions adhering only to each other to thereby secure said fronts and backs together along said opposed edges, is characterised in that said portions overlap opposite sides of each said insert at said opposed edges thereby solely to prevent shifting of said inserts parallel to a second opposed pair of free marginal edges, said insert being in contact with said portions but unattached thereto, means along said second edges securing said upper and lower plies together and preventing shifting of said insert parallel to said first edges, there being no means at
  • a continuous series of stuffed sealed envelope assemblies generally designated 10 are shown in Fig. 1 as constructed of superimposed continuous upper and lower plies 11 and 12 having spaced cross lines 13 of weakening therein so as to respectively define envelope front and back sheets 14 and 15 (Figs. 3 to 6).
  • Superimposed longitudinal lines 16 of weakening are provided in the upper and lower plies near opposite edges so as to define removable feed bands having spaced feed holes 17 therein.
  • a continuous intermediate web 18, shown in Fig. 2 is disposed between the upper and lower plies and has die cuts 19 formed therein extending along opposite sides of lines 13 of weakening.
  • the die cuts thereby define a series of insert sheets 21 having connecting portions 22 and 23 between adjoining sheets at opposite ends of the die cuts.
  • Plies 11 and 12 are respectively provided with confronting strips of securing means 24 and 25, such as self-stick adhesive, along opposing side edges thereof.
  • Strips 26 and 27 are likewise provided on the inner surfaces of the upper and lower plies in confronting relationship along and spaced slightly inwardly of cross lines 13 of weakening.
  • These strips may likewise comprise self-stick adhesive which, together with strips 24 and 25, may be of the conventional latex adhesive which adhere on contact or the heat sealing adhesive variety such that confronting strips will adhere only to each other at elevated temperatures but not to the insert sheets of the intermediate ply as will be hereinafter more fully described.
  • Such adhesive may therefore be active by simple contact or activated by pressure, by heat, or such self-stick adhesive may be of the type which is activated by remoistening or the type activated by radiation.
  • confronting strips of securing means may include material such as polyethylene which is activated upon application of heat thereto.
  • Strips 24 and 25 are disposed along opposite side edges 28 and 29 of inserts 21 and are of sufficient width as to lie both inwardly and outwardly of these side edges (Figs. 3 and 4).
  • confronting strips 26 and 27 of the securing means lie along opposing end edges 31 and 32 of the inserts and are of sufficient width as to lie both inwardly and outwardly of these end edges, as seen in Figs. 1, 3 and 5.
  • strips 24 and 25 adhere only to each other and not to any portion of the inserts along opposite edges 28 and 29.
  • confronting strips 26 and 27 adhere only to each other and to no portion of the inserts along opposing end edges 31 and 32.
  • Each insert 21, as shown for envelope assembly 10 of Fig. 3 is thereby immobilized between the envelope front and back while being in contact with the strips of securing means, but unattached thereto.
  • connections 22 and 23 are severed from the inserts during some convenient stage of the web processing operation. Such may be carried out by cutting connections 22 and 23 along lines 33a, shown in dotted outline in Fig. 2, so as to produce clean cuts 33. These cuts may be made through one of the outer plies such as lower ply 12, as shown at 34 in Fig. 6, - thereby serving the dual purpose of severing connections 22 and 23 from the insert sheets, and permitting any entrapped air within the sealed envelope assembly to escape. A completely flat envelope assembly is therefore made possible so as to avoid the "pillowed effect" normally occuring during the production of sealed envelopes.
  • the envelope assemblies produced according to the aforedescribed embodiment include free inserts which are maintained in registry between the envelope front and back without shifting relative thereto since strips 24 and 26 of the securing means respectively confronting strips 25 and 27 of the securing means are activated when brought into contact with one another, although the securing means is such that it will not adhere to any portion of the insert despite being in contact therewith.
  • the inserts nevertheless remain unattached to the confronting strips of securing means.
  • Such an arrangement is graphically illustrated in Figs. 4 and 5 where, for purposes of the description, the inserts are shown spaced from the strips of securing means when in fact they are in contact therewith but remain nevertheless unattached thereto.
  • the insert is accordingly maintained in a desired registration position within the envelope during processing thereof through the computer printing equipment.
  • a continuous series of stuffed sealed envelope assemblies generally designated 39 are shown in Fig. 7 as constructed of superimposed continuous upper and lower plies 41 and 42 having spaced transverse lines 43 of weakening therein for delimiting envelope front and back sheets 44 and 45 (Figs. 9 to 11).
  • a continuous intermediate ply 46 is located between the upper and lower plies and has die cuts 47 formed therein (see Fig. 8) at spaced locations so as to extend along opposite sides of transverse lines 43. These lines are likewise provided in the remainder of intermediate ply 46 in superimposed relationship with such lines provided in the upper and lower plies, so as to thereby define together with the die cuts a series of insert sheets 48 held together by connecting portions 49 at opposite ends of the die cuts. And, superimposed longitudinal lines 51 of weakening are provided in each of the plies along opposite longitudinal edges for delimiting feed bands 52 having spaced feed holes 53 therein for engaging the pins of a tractor pin feed device of web processing equipment.
  • the upper, intermediate and lower plies are interconnected together by means of longitudinal glue streams 54 and 55 lying inwardly of lines 51 of weakening. As seen in Fig. 10, these glue streams interconnect portions 49 of the intermediate ply with the upper and lower plies. And, the upper and lower plies 41 and 42 are respectively provided with confronting portions 56 and 57 of securing means, such as self-stick adhesive, along transverse lines 43 of weakening and extending between glue streams 54 and 55. These adhesive portions are of the same type of self-stick adhesive as described earlier with reference to securing strips 24 to 27. And, as shown in Figs. 7 and 11, such adhesive portions are of sufficient width as to lie both inwardly and outwardly of opposing side edges 58 and 59 of insert sheets 48.
  • portions 56 and 57 need not be applied in continuous cross strips to the upper and lower plies as shown in Fig. 7, but may instead by formed as a plurality of adhesive spots extending both inwardly and outwardly of opposing edges 58 and 59 of the inserts, without departing from the invention.
  • Such portions could likewise be applied to the upper and lower plies respectively as an interrupted longitudinal steam or as several interrupted longitudinal streams between glue streams 54 and 55.
  • Connecting portions 49 are severed from the inserts during some convenient stage of the web processing operation, similarly as described for connections 22 and 23 shown in the aforedescribed embodiment. Connecting portions 49 may be separated from the insert sheets by cutting along lines 61a, shown in phantom outline in Fig. 8, so as to produce clean cuts 61. The severed connecting portions 49 therefore define chip elements abutting opposite ends of the inserts for immobilizing them between the upper and lower plies together with confronting adhesive portions 56 and 57.
  • Longitudinal lines 62 and 63 of weakening are respectively provided in the upper and lower plies at one end of the envelope assemblies slightly inwardly of one of the feed strips 52 and inwardly of the adjacent end edges defined by cuts 61 of the inserts to thereby define a stub 64 which, upon removal, will serve to open the envelope and extract the insert sheet.
  • a thumb notch 65 may be formed at lines 62 and 63 so as to further overlap the insert sheet of each assembly thereby facilitating easier grasping of the stub.
  • the envelope assemblies produced in accordance with the Figs. 7 to 11 construction include free and unattached inserts held in a desired registration position between the fronts and backs of the envelopes by means of contacting securing portions 56 and 57 preventing the inserts from shifting longitudinally during web processing. And, any side shifting tendency is prevented by chip elements 49, although it should be pointed out that such side shifting is not likely to occur even without the provision of chips 49 since the snug embrace between the inserts and securing means 56 and 57 is sufficient to maintain the insert sheets in accurate registry within the envelope pockets of the assemblies.
