- the bag is inserted in the outer container, as indicated in Fig. 2, leaving an upwardly externally extending end G, and is then opened, and filled with a sufficient quantity of desired material or liquid, the bag illustrated being so made as to be liquid and leak proof.
- the next action is to close the bag and container simultaneously, to effect a liquid and leak proof sealing of the bagmouth, and to finally interengage and lock the extending bag mouth by infolding the ,bag mouth with the portion l0, and then completing this enclosure by latch looking. It makes no difference in, the final mouth sealing and locking, whether the steps about to be described are performed by hand or by an automatic sealing device, but it is intended to fiaps, which form the'sub-fiaps perform all of the erecting, lining and container closing by a. machine devised for this purpose.
- the opposed top, main end closing fiaps 6-8 are simultaneously moved inwardly towards meeting position by simultaneously pressing the opposed flaps I and II towards each other. Owing to triangular scoring on these I5I6 and I3--I4, this action causes the flaps 1 and I I to close in the top end of the bag and reforms the bellows-fold Bot bag'on both sides, as illustrated 'in' Figs. 2 and 6, and, at the same time, to draw the opposedfiaps 6 and 8 toward each other,
- this step also gradually bringing the open sides of the bag together, until finally, when this first step of closure is completed, the bag mouth is pinched shut, as shown in Fig. 7, the outer edge of the fiap 6 and the folded edge formed by score line h, fiap 9I0 being bent backwardly on the line h, and the flaps 6, I, B and II then act as pincers to hold the bag mouth closed on all four sides, with theexposed compressed portion G thereof extending above the confines of the closed flaps '6 and 8.
- edge h-of flap 8 and theedge of fiap 6 retain the seal cemented bag mouth until the cement has set. After'the cement has set, for the final closing of the top to lock the closureandto' reinforce the cemented seal against rupture, the
- fiap portion 9-10 is bent up parallel with the upstanding bag mouth G, Figs. 8 and 9, and the top portion of the bag mouth is folded and creased into an end lap G, and the flap portion I is folded thereover on score h, leaving the latch tongue T, upstanding. Then the fiap 8-9 is foldeddown onto flap 6, thus providing a second fold crease and the flap 8!! is then pressed downwardly, springing the top closure flaps 8-9-
- form a support for the flaps I 9 and' 22; and the tongue T will snap under the tongue S when the flap 22 is pressed on the flap I9.
- Said webs form a support cooperating with said inner flap I9 to prevent accidental depression of the flaps I9, 22 and to hold both flaps in normal latching position, and to prevent" excessive undesired depression of the inner flap during said snapping.
- Fig. 12' there is shown a fiat, paperboard blank for creating a slightly modified form of container.
- the blank is shown in full lines, and is underlaid by a registered, rectangular sheet of cellulosic liner-forming material C which may be affixed to the underface of the blankby gluing if desired.
- the container blank comprises two front-and rear forming'panels 4 and 2, respectively which are defined from one another by being scored from anintermediate side-forming panel 3, by score lines'd and 0, respectively.
- Front body panel 4 is providedwith opposed end flaps 6-4, which are defined therefrom by common score lines and e.
- the said flaps are provided with slitted latch tongues S-- S.
- Side forming panel 3 is provided at eachof its opposite ends with. infolding top end. closing with triangular score lines '0' and p, thus provid ing triangular sub-flaps l5, l6 and 1.:
- These webbed flaps l-l61 are;defined from panel 4 by common score lines I and e, and when in-' folded. form connected bellows-like pleated flaps.
- Rear-body-forming main panel-lie defined from the side-forming panels I and 3, by score lines D and c, respectivelyeand on each of its opposite ends is provided with composite infolding endclosing flaps 8 9l0, said flaps being defined ffr'ompanel, 2 by common score lines 1 and e.
- Side-forming panel I is defined from rear panel 2 by. a score line b and is defined from the glue lap 5 by score line. a.
- flaps when the container is erected, are opposed. to the flaps ,l-l5l6, and they function the same as said latter flaps, as will belaterydisclosed in detail.
- Glue lap 5 is more extensive than the glue lap 5 of Fig. l., and is provided with rectangular corner overlaps l2 at its opposite ends these being defined by common score lines 1, e and a.
- the cellulosic liner sheet C Fig. 12,.is fiatgand.
- the sheet is slightly narrower than the length of panel 2 and its flaps In, and length-wise it terminates at aboutthe mid-section of glue lapi, and at its opposite end extends beyond; the limits of the blank-thus to' form a marginal extension aroundthe edgesof panelsBandl.
- This structural assembly of the inner and container blanks lines the inner face of the con tainer with a perfectly sealed, leak-proof inner.
- the liner forms an open ended, tubular formation; both ends beingopen,
- the container is thus erectable as'described for the container
- the and closing flaps and extended liner ends are closed and sealed in a manner exactly as describedfor the container of Fig, 1, In the erectedcontainerof Fig. 12, because of the, similarity of; the'end closing flapsthereon, either-end may be top or bottom.

The bag is inserted in the outer container, as indicated in Fig. 2, leaving an upwardly externally extending end G, and is then opened, and filled with a sufficient quantity of desired material or liquid, the bag illustrated being so made as to be liquid and leak proof.
The next action is to close the bag and container simultaneously, to effect a liquid and leak proof sealing of the bagmouth, and to finally interengage and lock the extending bag mouth by infolding the ,bag mouth with the portion l0, and then completing this enclosure by latch looking. It makes no difference in, the final mouth sealing and locking, whether the steps about to be described are performed by hand or by an automatic sealing device, but it is intended to fiaps, which form the'sub-fiaps perform all of the erecting, lining and container closing by a. machine devised for this purpose.
After the bag has been inserted in the container and filled, the opposed top, main end closing fiaps 6-8 are simultaneously moved inwardly towards meeting position by simultaneously pressing the opposed flaps I and II towards each other. Owing to triangular scoring on these I5I6 and I3--I4, this action causes the flaps 1 and I I to close in the top end of the bag and reforms the bellows-fold Bot bag'on both sides, as illustrated 'in' Figs. 2 and 6, and, at the same time, to draw the opposedfiaps 6 and 8 toward each other,
this step also gradually bringing the open sides of the bag together, until finally, when this first step of closure is completed, the bag mouth is pinched shut, as shown in Fig. 7, the outer edge of the fiap 6 and the folded edge formed by score line h, fiap 9I0 being bent backwardly on the line h, and the flaps 6, I, B and II then act as pincers to hold the bag mouth closed on all four sides, with theexposed compressed portion G thereof extending above the confines of the closed flaps '6 and 8. After this step has been' performed the" closed bag mouth G, Fig. '7, is
' then tightly sealed by pressing opposed heater jaws H-H on opposite'sides of the closed mouth end. These jaws are electrically heated, and when applied under heat, cause a cement, previously applied to the inner faces of 'the bag mouth, to soften and then to set,-l'eaving the bag mouthcompletely sealed in a liquid-proof man ner.- After the cement has been softened, the
edge h-of flap 8 and theedge of fiap 6, retain the seal cemented bag mouth until the cement has set. After'the cement has set, for the final closing of the top to lock the closureandto' reinforce the cemented seal against rupture, the
fiap portion 9-10 is bent up parallel with the upstanding bag mouth G, Figs. 8 and 9, and the top portion of the bag mouth is folded and creased into an end lap G, and the flap portion I is folded thereover on score h, leaving the latch tongue T, upstanding. Then the fiap 8-9 is foldeddown onto flap 6, thus providing a second fold crease and the flap 8!! is then pressed downwardly, springing the top closure flaps 8-9-|0 and 6, until the latch tongue T springs or snaps under and into the 'slitted latch locking member S, as shown in Figs. 10 and 11, thus locking the 'top end closing flaps over the cemented bag mouth.
When and after the carton is erected, the webs I'I, I8 and 20, 2| form a support for the flaps I 9 and' 22; and the tongue T will snap under the tongue S when the flap 22 is pressed on the flap I9. Said webs form a support cooperating with said inner flap I9 to prevent accidental depression of the flaps I9, 22 and to hold both flaps in normal latching position, and to prevent" excessive undesired depression of the inner flap during said snapping.
In Fig. 12'there is shown a fiat, paperboard blank for creating a slightly modified form of container. The blank is shown in full lines, and is underlaid by a registered, rectangular sheet of cellulosic liner-forming material C which may be affixed to the underface of the blankby gluing if desired. The container blank comprises two front-and rear forming'panels 4 and 2, respectively which are defined from one another by being scored from anintermediate side-forming panel 3, by score lines'd and 0, respectively. Front body panel 4 is providedwith opposed end flaps 6-4, which are defined therefrom by common score lines and e. The said flaps are provided with slitted latch tongues S-- S.
Side-forming panel I is defined from rear panel 2 by. a score line b and is defined from the glue lap 5 by score line. a. Panel .1 is provided at its opposite ends with bellows-like end closing, flaps ll--l3--l4 which are defined from panel by. common score lines 1 and;e,= andare defined fromeachother by diagonal score lines op, to form connected sub-flaps lI,--l3 and I4. These flaps when the container is erected, are opposed. to the flaps ,l-l5l6, and they function the same as said latter flaps, as will belaterydisclosed in detail.
Glue lap 5 is more extensive than the glue lap 5 of Fig. l., and is provided with rectangular corner overlaps l2 at its opposite ends these being defined by common score lines 1, e and a.
The cellulosic liner sheet C, Fig. 12,.is fiatgand.
' not in a pre-formedbag structure as shown in- Fig. 3, and as seen in Fig. 12, the sheetis slightly narrower than the length of panel 2 and its flaps In, and length-wise it terminates at aboutthe mid-section of glue lapi, and at its opposite end extends beyond; the limits of the blank-thus to' form a marginal extension aroundthe edgesof panelsBandl.
In assembling anderecting the container from the blank of Fig. 12, after theblank has the cellulosic sheet liner adhered thereto, the blank and sheet liner C, are then turnedover to expose the lined blanksurface face upwards,,then glue is applied to the liner margin which covers the I glue lap -5 and the glue lap margin t, .and glue is also applied to the marginal facem Of' the liner at its opposite end, the panels 4-3 are then bent upward on score line 0, and then bent down until the liner portion on panels 43 comes into.- Then contact withthe liner face of panels 'l2. the glue lap; 5 is bent upwardly and over and downwardly to bring its glued liner and flap,
portion t. into over-folded contact with-the glued liner margin m and the, marginal edge of panel 4,v as illustrated in the enlarged sectional view shown in Fig. 13, wherein the overlap described is shown before the final seal. 1 v
This structural assembly of the inner and container blanks lines the inner face of the con tainer with a perfectly sealed, leak-proof inner.
liner, the jointureat the overlappedportions of the marginallyadhered liner edgesandthe container-lap'adherence forming an impervious joint. The liner, as above described, forms an open ended, tubular formation; both ends beingopen,
of Fig. 2.
and as the container is initially made fiat, being folded on its .s core lines a-and c, the container is thus erectable as'described for the container After the erection of, the blank into rectangular container form, the and closing flaps and extended liner ends are closed and sealed in a manner exactly as describedfor the container of Fig, 1, In the erectedcontainerof Fig. 12, because of the, similarity of; the'end closing flapsthereon, either-end may be top or bottom.
ll-ua-qtand 1-15-15, are infolded simul ta neously, and this action'simultaneously draws down the closingxflaps 8+9 l0, and this action after folding-the portions 9 outwardly on score line h, shownin Fig. 7-, and from then on the'seouence of steps of heat-sealing and final latching closure, after fillingis identical with the steps shown in Figs. -7, 8, 9, l0 and 11. Aswill be apprehendedboth ends of the container of Fig. 12 are identically. constructed and closed. This container, like the one shown in Fig.3, is susceptible of either manual, or machine-actu ated, filling, heat-sealing and closing. i
