United States Patent 3,297,225 PACKAGING William R. Scholle, Long Beach, Calif., assignor to Scholle Container Corporation, Chicago, 111., a corporation of Illinois Filed June 9, 1964, Ser. No. 373,627 3 Claims. (Cl. 229-14) This invention relates to improvements in packaging and more particularly to that class of packages where a flexible plastic bag, such as of polyethylene, and containing, or adapted to contain a liquid such as a chemical or a food, is sealed and disposed within a rectangular rigid paperboard container.

One method of dispensing the contents of a package of the aforesaid class is to pierce a side wall of the container, including its liner bag, by means of a probe to the outer end of which there may be connected a conduit or spigot. As an aid in maintaining the liner bag taut and retained adjacent the carton wall at the area of probing it is desirable that means be provided to secure the liner bag, or a portion thereof, at or adjacent to said area.

As will appear from the following specification and accompanying drawings, the foregoing object is accomplished in a simple and effective manner.

In the accompanying drawings,

FIG. 1 is a perspective view of one end, i.e., the bottom of a paperboard carton, the carton having disposed therein a plastic liner bag, the end flap of the carton being open.

FIG. 2 is a progressive view of the carton of FIG. 1 showing one of the end flaps closed down and a portion or corner of the liner bag projecting outwardly thereof and outwardly of the carton side wall. 1

FIG. 3 is a further progressive view of the carton of FIGS. 1 and 2 wherein the outwardly extending liner bag is folded down and engaged between the first folded down flap of FIG. 2 and another flap sequentially folded down thereover.

FIG. 4 is a perspective view with all the end flaps of the carton bottom secured down.

FIG. 5 is a perspective view of the carton of FIG. 4 inverted in operative position, with parts broken away, and a probe adapted to pierce the assembly.

FIG. 6 is a fragmentary sectional view of the carton assembly of the previous figures with a dispensing probe projecting through a container wall and the adjacent anchored liner bag.

Referring to the drawings, thereference numeral 10 generally indicates a rigid paperboard rectangular carton comprising side and end walls 11 and opposedfull side flaps 12 and 14 hinged to opposed side walls, and opposed end half-flaps 13, 13 hinged to opposed end walls, the bottom end only being shown. It will be understood that the opposed or top forming end of the carton is provided with similar closure flaps.

Disposed within thecarton 10 is aliner bag 15, of the character previously described. This liner bag is conveniently of pillow-shaped character composed of tubular material transversely heat sealed at its opposed ends as at 16. End portions of the bag in the form ofcorners 17 and 18 are generally folded down inside the carton against the first folded down side flap. In accordance with the present invention, when thefirst side flap 12 is folded down, thebag corner 17 is permitted to remain inwardly whereas thecorner 18 is caused to project outwardly. (Although not so illustrated, it will be understood that thecorner 17 can also be permitted to remain outwardly offlap 12.)

Thereafter theend flaps 13, 13 are closed down and adhesively secured to theflap 12, with thebag corner 18 3,297,225 Patented Jan. 10, 1867 secured between theflap 12 and one or bothflaps 13. Thecorner 18 is desirably also adhesively united to one or both of its embracing carton flaps. After theflaps 13, 13 are sealed down, theflap 14 is sealed thereover to complete the carton bottom assembly, as shown in FIG. 4, and then inverted for use, as shown in FIGS. 5 and 6.

As shown in the drawings, one of the end walls 11 is suitably marked or is actually formed with a knock-out perforatedportion 19 adjacent to the carton bottom and thefold line 20, and where thecorner 13 is folded over one edge offlap 12 and held between flap'12 and one of theflaps 13. In this manner theliner bag 15 will be held stretched or taut at the area or point where it will be pierced by theprobe 21. This also permits the probe to cleanly pierce the liner bag and cause the liner bag to be held in position so that its piercedportion 22 will readily remain free of theprobe apertures 23 and permit smooth flow of theliquid contents 24 outwardly throughspigot 25, without leakage of the liquid between the liner bag and the carton wall.

Although not shown, it will be understood that the liner bag can have a reinforcing patch of flexible plastic material adhered over the area to be pierced byprobe 21.

Further, although for clearness of illustration I have shown theliner bag 15 to be composed of a single ply, it will be understood that, as is well known, it can be composed of two or more plies.

I claim:

1. A lined container comprising an outer rigid rectangular paperboard container body including side and end walls, first and second opposed full end closure flaps hinged to said side walls, and opposed half flaps hinged to said end walls, a pillow-shaped plastic flexible liner bag disposed in same rigid container with at least one corner portion projecting outwardly of said side walls and folded about a lateral edge of said first side flap with one of said end flaps folded thereover, said second side flap lying in sealed engagement to and over said end flaps, one of said end walls including a defined probing area disposed adjacent to the hinge line of its end closure flap and adjacent to the lateral edge of said first side closure flap about which said bag corner portion is folded.

2. The container of claim 1 wherein said liner bag corner is further adhesively secured between said first side flap and said overfolded end flap.

3. The method of engaging a flexible pillow-shaped liner bag to an embracing rigid paperboard container body, said body including side and end walls, first and second opposed full side flaps hinged to said side walls, opposed half-flaps hinged to said end walls, a defined probing area being disposed on one of said end walls adjacent the hinge line of its end flap, first folding down said first side flap, extending a corner of said bag outwardly of said side walls and folding about a lateral edge of said first flap adjacent to said end wall probing area, next folding down said end flaps, and then sealing thereover said second side flap.
