FIG. 6 is a fragmentary perspective view with the inner container positioned in the outer container.

FIG. 7 is a fragmentary perspective View showing the outer container partially closed and the spout extending through the re-entrant portion of one of the flaps.

FIG. 8 is a fragmentary perspective view similar to FIG. 7 with the spout moved into pinched engagement with a closure flap.

FIG. 9 is a fragmentary perspective View with a portion of the closure severed and hinged back and the spout and container in position for pouring contents from the inner container.

FIG. 10 is a fragmentary perspective view with a spout re-engaged in pinched relation after pouring a portion of the contents from the container.

FIG. 11 is a fragmentary perspective view with the access flap closed and secured in place.

Referring more in detail to the drawings:

The numeral 1 generally designates a package composed of an outer container 2 preferably made of relatively rigid material such as double face corrugated paperboard and an inner container 3 preferably made of thin, flexible, fluid-tight plastic such as polyethylene and the like which is relatively inert with respect to fluent materials packaged therein. The inner container 3 is suitably formed from sheet material or film of suitable thickness, as for example five mils, suitably sealed to provide a bag-like formation having closed bottom 4, side walls 5 and a closed top 6 except for a pouring spout 7 made integral with the inner container and extending substantially beyond the upper closed end 6 thereof, said inner container being of a suitable size to substantially fill the outer container.

The outer container or carton 2 includes a body portion 8 having opposed sides 9 and iii and 11 and 12 with bottom flaps hinged on the lower edges of the side walls to form the bottom of the outer container or carton. In the illustrated structure the bottom flaps 13, 14, 15 and 16 are hinged on the lower edges 17 of the side walls 9, 10, ii and 12 respectively. The upper end or top closure of he outer container or carton is formed by opposed flaps l8, 19, 2'3; and 21 hinged on the top edges 22 of the side walls 9, 10, Jill and 12 respectively. The outer carton is usually formed from a flat blank 23 appropriately scored and cut to provide the side walls and top and bottom flaps with score lines defining fold lines 24, 25 and 2% between side walls 9 and 11, lit and 11 and 10 and 12. respectively. The side walls 9 and 12 have outer edges 27 and 28 respectively which when the outer carton is set up or erected are secured in engaged relation as by a tape 29 or other suitable conventional manner to retain the side walls in position to define a tubular interior 3%, preferably of rectangular cross section. The blank also preferably has score lines 31 and 32 along the bottom edges 17 and top edges 22 of the side walls whereby the bottom and top flaps are extensions of the side walls and hinged thereto.

In the illustrated structure, the side walls 9 and 10 have hand holes 33 cut therefrom to facilitate handling of the package. Also, the top flap 18 has a re-entrant portion 34 through which the spout 7 is adapted to extend. The re-entrant portion in the illustrated structure is substantially a quarter circle cutout extending from an end 35 of the flap is to the top edge 22. of the wall 9. The reentrant portion also includes a slot 36 extending from the cut-out on re-entrant portion 34, remote from the end 35, and terminating in a small opening 37. The slot 36 and opening 37 being of such size in width and diameter respectively that when the spout 7 is positioned therein, the edges 38 defining the slot 36 and opening 37 squeeze or pinch the spout '7 to form a substantially air-tight seal. The flap 21 has severance lines or perforations 39 extending from an end 40 of said flap and then inwardly to the top edge 22 of the side wall 12 whereby, when the lineof perforations is cut an access member or flap 41 is defined that is hinged tothe sidewall 12. The access flap 41 is positioned over the re-entrant opening-in the flap 18 when the outer cartonis erected and closed.

The bottom closure of the illustrated structure has an inner flap- 15- formed as an extension of the side wall 1-1 and extending from the loweredge 17 thereof a distance cor-responding to the width of the side walls 9' and 10 whereby the flap substantially corresponds to the cross sectional area of the interior 3t} ofthe outer carton. The

flaps 13 and 14 have portions adjacent the flap 15 cut" away, the edges 42 of said flaps being in angular relation to the lower edges 17 of the respective side walls and then terminating as at 43 in outwardly extending edges 44 which cooperate with the oppositeedges 45 to define extensions 46 of reduced width. The flap 16 has side edges 47 converging from the lower edge 17 of a respective wall and terminating as at 48 in parallel side edges 49' that define an extension 56 Scorelines 51 extend across the extension Siiand are spaced from the lower edge 17 of the wall 12 a distance substantially corresponding to the width of the extensions 46.

In assembling the outer container from a blank such as illustrated in FIG. 4-the container body is folded on the lines 24, andZ to bring the'edges 27 and 2% together and said edges are secured by suitable fastening devices such as tape 29. In this position, the outer carton or container may be further folded on the lineZS to a flat condition for shipping to a point of use. When the outer container or carton is to be set up and the inner container inserted therein and filled, the outer container is opened whereby the sides define a rectangular cross section and then the lower flap is hinged upwardly inside of the inner space 30. The bottom flaps 13 and M are then folded where one overlies the other and the bottom flap le'folded under the outermost of the flaps 13 and 14 and the extension 5% turned upwardly on the score line 51 and then reversely to overlie the uppermost of the exten sion portion of the flaps 13 and 14. The bottom flap 15 is then moved downwardly to overlie the extension 5% to retain same in place forming a self-locking bottom for the-outer container. The inner container or bag 3 is then positioned in the outer container 2 with the spout 7 at thecorner adjacent the re-entrant portion 34- of the flap 18. Theinner container or bag is then filledwith suitable fluent material such as milkor the like, and if desired, the adjacent edges of the free end of the spout 7 may be heat sealed as at 52. The flaps'18 and 1% are then folded inwardly to overlie the top portion of the flexible inner container whereby thespout 7 extends through the reentrant portion 34. The flap 2% is then folded inwardly to overlie the adjacent portions of the flaps l8 and 19 and the spout is preferably twisted and moved into the slot 36 or opening 37 and then folded tooverlie the adjacent portionof the flap 13. The flap 21 is then folded to overlie and compress the spout against the flap 13 and is secured in place as by tape 53 securing adjacent edges of the flaps 20 and 21 as illustrated in FIGS. 1 and 10-.

When it is desired to dispense some of the fluid in the container, the flap 21 is severed on the severance line or perforations 39 to provide the access flap 41 which is hinged upwardly providing access to the spout 7. The spout is pulled from the slot 36 whereby said spout extends through the re-entrant portion 34. The end of the spout is opened and the container tilted or inverted to pour material from the inner container as illustrated in FIG. 9. After a desired quantity of the material is poured from the container, the container is placed upright and the'spout twisted and the twisted portion moved into the slot 36 or opening 37 whereby said spout is pinched to form a seal preventing entry of air or the like into the interior of the inner container. Theportion of the, spout extending above the flap 18 is then bent over to overlie said-flap and'the access'flap 41 moved to closedposition to compress the spout against the flap 13. A suitable elongate rod or strip 54 is inserted to underlie a portion of the closure flaps and overlie the access flap 41 as illustrated in FIG. 11 .to retain the access flap 41 in closed position. When it is desired to dispense more the-contents from the inner container, the locking member or rod 54 is removed and the access flap 41 elevated and the spout again moved to extend through the re-entrant portion 34 whereby further dispensing of the contents may be accomplished with the remaining portions of the closure flaps retaining the inner container bodily in the outer container as illustrated in FIG. 9. The process of periodic dispensing of portions of the contents of the container may be repeated and the spout closed to seal the inner container as often as desired until the container is empty.

The package as illustrated and described has the advantage of being capable of being shipped in knocked down condition and .erected at the point of use. It occupies a minimum of space in proportion to its cubic capacity and it is easily disposable, but maybe reused if desired particularly by replacement of the inner container.
