Application December 1, 1955, serial No. 551,550 4 claims. t (cl. 229-55) This invention relates to paper bags, with particular reference to gusseted, long-lip, square bags.
One of ythe objects of the invention is to provide a gusseted bag of the type just referred to in which the bottom of the bag is superior to that in bagsof this gen-` eral type as heretofore constructed in that provision is made to hold the ends of the gussets securely in place, y
In the accompanying drawings, wherein two embodiments of the invention have been illustrated,
Fig. 1 is a plan view of the bagblank before folding;
Fig. 2 is `a front elevation, with one corner in` section, of a bag fabricated from the blank of Fig. 1;
Fig. 3 is a plan View of another bag blank, before folding, incorporating a second embodiment of the invention; and
Fig. 4 is a view similar to Fig. 2 showingV a bag fabricated from the bag blank of Fig. 3.
Referring, first of all, to the embodiment ofthe invention as illustrated in Figs. l and 2:
The bag is fabricated from the single'blank illustrated in Fig. 1, this blank providing a panel or wall 2, seam area 4, panel or wall 6, and gusset areas 8 and 10, the gusset area 8 being intermediate panel 2 and seam :area 4, and gusset area 10 being intermediate panels 2 :and 6.
As will be lseen from Fig. 1, the blank is shaped to provide a lip 12 at one side edge of the panel or wall 2, the lip projecting beyond the upper edge panel and embracing or overlapping the upper end of the seam 'area 4 as well as the upper end of 'gusset area n 8. At the other side edge of the panel or wall 2 is a projecting lip 16, which, like the lip 12, projects beyond the upper edge 14 of the front panel or wall 2. The lip 16 embraces or overlaps the upper end of the panel or wall 6 and the upper end of gusset area 10.`
The two outer edges 18 and 20 of the two lips 12 and 16, respectively, are continuations of the straight edges 22 `and 24 of the blank. The outer end 26 of the lip 12, however, beginning at a point just above the upper edge of panel 14, inclines Aoutwardly at an obtusey angle with respect to this edge of the panel. This incline extends to the inner edge of the seam area 4 so as to extend completely across the gusset area 8. Thel outer end 28 of the lip 16 is inclined outwardlyv with respect to the upper transverse edge 14 of the panel 2 in the opposite direction to the end 26 of lip 12 but at the same angle to the upper edge 14 of panel 2 as the end 26 of lip 12. lt should be noted furthermore that the inner ends of the inclined ends 26 and 28 of the lips 12 and 16 are curved or convexedY slightly, as indicated 14 of the United States; PatentO at 30, for a purpose to be brought out presently. It`
As already noted, the lower or bottom end of the bag4 blank is complementary to the upper end, so that a multiplicity of blanks may be formed from a continuous web without waste of material. As a result of this cornplementary feature, the lower end of the panel 2, the side edges 27 and 29 of this lip inclining outwardly in opposite directions at an obtuse angle with respect to the lower transverse edge of the-lip. The inclined edge 27 of this lip extends across the lower end of gusset area 8 to the inner edge of the seam area 4, whilethe inclined edge 29 of the lip extends across the gusset area 10 to the inner edge of panel 6. By inclining the edges 27 and 29, the outer half 9 of gusset area 8 at the lower end of this area is shorter than the inner half 13 of the gusset at the same end, and the outer half 11 of gusset area 10 at its lower end is shorter than the inner half 15 of this gusset at lthis end. It will be observed also that the material of the blank at the inner ends of the inclined edges 27 and 29 will be concaved, as shown at 31, because of the convex ends 30 of the edges 26 and 28.
In forming a bag from the blank of Fig. 1, the inner halves 13 and 15 of the gusset areas are infolded over uponrpanel 2 along the longitudinal fold lines 38 and 40, which extend along each side edge of this panel. The material is then outfolded along the longitudinal Yfold lines 42 .and 44, to produce a gusset along the sides of panel 2. The
material is then infolded along longitudinal fold lines 46 and 48. ln making the fold along lines 46 and 48, the side seam area 4 and panel 6 will be infolded, to bring the outer edge portion of panel 6 into overlapping relation to the side seam area 4. When the area 4 'and outer edge portion of panel 6 are pasted together, a full side seam is provided.
To bottom the bag the lip 32 at the lower end of the blank is folded over upon the outer face of panel 6 along the transverse fold line 52. This fold line 52, as will be observed from Fig. l in particular, is below the lower end 54 of seam area 4 and below the lower end 56 of rear panel 6 but is so positioned as to extend not only completely across the lower end of front panel 2 but completely across the inner halves 13 and 15 of the gusset areas 8 and 10 as well. This fold line, however, extends only partially across the outer halves 9 and 11 of the gusset areas 8 and 10, intersecting the inclined edges 27 and 29 of the lip 32 intermediate the fold lines 42 and 46 and intermediate the fold lines 44 and 48. Consequently, when the projecting lip 32 is folded over upon the panel 6 along the fold line 52, the lower ends 58 and 60 of the j inner halves 13 and 15 of gusset areas 8 and 10 Will be folded over so as to lie intermediate the inner face of the projecting lip 32 and the outer face of the panel 6. At the same time, the areas or corners 62 and 64 of the outer halves 9 and 11 of the gusset areas 8 and 10 will have l been `folded over upon the outer face of the outer halves ofthe gusset areas so as to become pinched between ,they folded-over portions 58 and 60 of the inner halves 13 and 15 of the gusset areas and the outer faces of the outer halves 9 and 11 of the gusset areas. It will be understood that in the bottoming operation the lip 32 is pasted to the outer face of panel 2, and, by convexing the inner ends of the inclined ends 26 and 28 of the lips 12 and 16.50
that the inner ends of the edges 27 and 29 of the lip 32f are concaved, the full width of that portion of. thelip..1 composed of the end of panel 2 is available for pasting. f
From the foregoing it willbe seen that the construction Patented June `3, 1958v a projecting lip 32 is provided at.
above described provides a gusseted, long-lip, square bag in which, in bottoming the bag, the projecting lip von the bottom end of the front wall of to the outer face of the rear wall of the bag, the ends of the twougussets being infolded with the` portions 62 and 6:4;.of the outer half or" each ,gusset area pinched between the inner `halt' of each gusset area and the facey of the outen half, so that displacement of the gusset endsat the corners` of the bag bottom is prevented.
In the embodiment of the invention illustrated' in Figs. 3; and 4;, the bag blank provides a panel or wallA 102', seam area .104', panel or wall 106, and gusset areas 108 and 110, the gusset area 108 being intermediateA panel 102 andl seam area 1M, and gusset area 110` being intermediate panels102 and 106.
As will be apparent from Fig. 3, the blank is so cut or shaped that a projecting lip 112 projects beyond the upper edge 114 of the panel 102 at one side edge ofthe panel, this lip embracing the upper ends of the seam area 104 and gusset area 108, while at the other side edge of the panel- 102 a projecting lip 116 is provided, which projects beyond theupper edge 114 of the panel 102 and embraces the. upper ends of panel 106 and gusset area 110.
The inner edge 126 of the lip 112 inclines outwardly at an obtuse angle with respect to the upper-edge 11-4 of panel 102, the incline terminating at its outer end at the innenedge of seam area 104. The inner edge 12-8 of the lip 116iinclines outwardly at an obtuse angle with respect to the upper edge 114 of panel 102, this incline terminating at its outer end at the inner-edge of panel 106. The slats of the lip edges 126 and 1128 with respect to the upper edge 1111 of panel102 are alike.
As distinguished from the blank of Fig. l, the inner ends of the inclined or slanting edges 126 and 128 are notconvex but continue at an inclination to a short distance beyond'the side edges of the panel 102'.
As in the embodiment of the invention illustrated in Figs. l and 2, the lower end of the blank of Fig. 3 is complementary to the upper end. As a result, the lower end of panel 102 has a projecting lip 132, the side edges 12'7 and 129L of which incline outwardly at an obtuse angle with respect to the lower edge of the lip. The inclined edge 127'` extends across the gusset area 108 and terminates at the inner edge of the seam area 104, while the inclinedk edge 129 extends across the gusset area 110 and terminates at the inner edge of panel 106.
In forming a bag from the blank of Fig. 3, the blank is infolded along the longitudinal fold lines 138 and 140 at each side of/ panel 162; The blank is then outf'olded along longitudinal fold lines 142 and 144' and then infoldedl againA along longitudinal fold lines 146 and 148. TheseA folds will-produce a longitudinal gusset along each side off'the-pa-nel 102; and the seam area 104 and panel 106 will have been overlapped, so that, when pasted, a
fullside seam is provided.
The bag is bottomed by 4folding the lip 132 at the lower end of the blank over upon the outer face of panel 106l alongthe transverse fold line 152. This fold line is below the lower end 154 of seam area 104 and the lowerend 156 of rear panel 106 but is so positioned as to extend not only completely across the lower end of front panel 102 but the inner halves 113 and 115 oftthe gusset areas S and 110 as well. This fold line, however, extends only partially across the outer halves 109 and 111 of the gussetl areas intersecting the inclined edges 132-7 and 129 of the lip 132 intermediateV the fold lines 1421and`146 and intermediate the fold lines 144 and 148;V Consequently, when lip `132 is folded over upon the panel 106, the lower ends 158 and 160 of the inner halves 113 and 115 of the gusset areas will be foldedl over so as to lie intermediate the inner face of-the lip 132 and outer face of panel 106. At the same ife., the` areas or corners 162 and 164 of the outer halves 109 and 111 of` the gusset areas will havebeen folded over upon the outer face of theU outer halvesof the bag is pasted directlyV 4 the gusset areas, to become pinched between the -foldedover-portions 158v and 160 ofthe inner halves 113 andv of the gusset areas and the outer face of the outer halves 109 and 111 of the gusset areas. It will be understood that lip 132 is nally pasted to the outer face of panel 102. It will be appreciated that, because the two ends of the blank are complementary, the side edges 127 and 129 of the lip 132 terminate at their inner ends a short distance inside the fold lines 138 and 140 or the sides of; the panel 1502, so that a vpasting area is provided at the end off the lip 132 extending from fold line 138 tofold line 140.
It will tbe apparent that in both embodiments illustrated' and described a construction is provided whereby a gusseted bag is produced in,- which displacement of the gussets at the two corners of the bag bottom with consequent leakage of the bag contents in prevented.
It is to be understood that changes may be made in the constructions` disclosed, within the purview of' the invention.
