Figure 6 shows-the containergenerally designated 10 comprising arectangular prism, in this' instance square or parallelepiped as shown. The prism 10 isa box comprisedof four rectangular side: walls --11, two of which are joined attheir comers by a tape 12, and with a top 13 andrbottom 14.-

Y The box is usually formed from a fiat blank appropriatelyrscored and out to-iprovide the sidewalls 11 and top 13 and'ibottomfll l. 2 Usually it is of corrugated or chip board. The top' 13 comprises two flaps-13A secured to opposed wallswll 1 and-two fflapsi13B secured to the othen,. .opposedwalls"11. Likewise, the bottom cornprises;.similarrflaps'="14A and 14B; When the'box is set up asyshown in Figures. 1 :and 6, the flaps 13A or 13B arerfoldedqinwardlyand flaps 13B 0r 13A respec- :tively are:folded thereover and adhesively secured, stapled, tapedor; otherwise. fixedly positioned with respect thereto. The same is true with the flaps 14A and 143 for the bottomm .f: 3;; Y .1 I Flaps 14A as shown in Figure l are in this instance each provided withra semi-circular aperture which apertures-are positioned in abutment and cooperation with anapertu're in :one of the flaps: 14B to form a circular hole 15 .fora tube i16'"as subsequently explained. -,Theapertureinflapi14B is circular-and in co-operation with the semircircular cutoutsinflaps -14A,'completes the hole "15 throughsth'e bottom 14 of thebox. In'=this instance, the hole :15 is positioned along a median line through the bottom 14 intone direction and approximately mid-wayibetween one of the Walls 11 and a median line in the other direction, although it" may be otherwise positioned and other-than circular configurations may be'rprovided. I t W a The liner 20 provides a fluid tight container or bag closed to atmosphere and having a vent means. In this instance it. comprises a "tubular section, which when in the position shown in Figure 2"provides opposed flat wall portions-21in abutment havingedges '22 and 23. The wall portions adjacent edges 23 "are secured together, in thisainstance by heat-sealing, "although adhesive or tape may be usedp-The portions ofthe walls 21 adjacent edges22 rarevlikewise sealed or secured along the dotteda 'liner; 22A after the fluid has been introduced into the linerncwz a 4 1 I lee Positioned on one of the walls 21 is a vent connected to hose 16 and so positioned that the vent will coincide with the aperture formed by hole when the linerv is in the inserted position of Figure 4. This will also be apparent by reference to Figure 1.

The vent comprises a conical member having a peripheral annular flange 26 secured to the wall 2 1, in this .instance by heat-sealing, and'provided with a central "aperture which leads to the interior of the liner or liner. The plugged end may be provided with an integral or assembled plug.

When the liner 21 is filled with fluid and the edges 22 joined, and it is inserted within the outer shell or container 17, it will take the configuration of the container as shown best in Figure '1. Because the liner 21 is in the nature of a flat folded bag when empty, as shown in Figure 2, when it is confined to a rectangular prism by shell 17 triangular gores or ends 34 will be formed at each side of the bottom of the liner and similar gores will be formed at each side of the top of the liner. They may be folded against the side walls 11A of the liner as shown in Figure 1 or gores 35 may be folded over the top 13C of the liner into opposed position. Gores 34 may also be folded over the bottom 14C of the liner into oppositely directed relation.

The liner 21,has been shown positioned so that seamed edges 22 and 23 coincide with a median line between two of the walls 11 of the container or shell 17. However,

the liner could be so positioned that these edges form a diagonal between two opposed corners formed by the intersection of walls 11, or otherwise as desired. When the corner opening of Figure 6 is being utilized, it is preferred to position these edges on the diagonal.

Likewise, while it is the preferred form of liner to make it from a section of seamless tubing folded so that portions of its walls are in fiatwise abutment the liner could be made in the form of a gusseted bag, an intucked bag or any other suitable construction, asin a plurality of pieces, to conform to the interior of the shell 17.

As shown in Figure 1 the walls 11 are reinforced with an inner reinforcing rectangular tubular ply 35, although this may be dispensed with as desired.

A removable base cover 40 comprises a rectangular pan adapted to fit over the bottom portions of the walls 11 as shown in Figure 4 with the inner surface of stub walls 11C thereof in abutment with the exterior surface of walls 11, the interior dimension between walls 11C being slightly greater than the exterior dimension between walls 11. Base cover 40 is provided with a bottom formed by flaps 14C and 14D similar to flaps 14A and 1413 for shell 17. Two spacers 41 are positioned in opposed relation within the cover 40 and secured to the bottom thereof as shown in Figure 1. The spacers in this instance comprises multiple plies of corrugated board, although multiple plies of chip board or other spacers may be used. These serve to provide an upwardly off-set bottom for the cover 40 having 'a central depression 42. As shown, the spacers are secured to bottom 40 by adhesive, although they may be otherwise secured or loose as desired. Furthermore, in some instances, it may be desirable to secure the spacers 41 to the bottom 14 of the shell 17, as shown in Figure 10. In Figure 5, the liner 21 has been positioned within the shell 17 and filled. The vent 25 has been positioned to correspond with the aperture 15 in the bottom 14and hose 16 extends therethrough and is coiled at 43 to seat in the depression 42 between spacers 41. It is retained in position by an adhesive tape 44 secured to the larger adhesive tape 45 which tape is shown retaining the flaps 14A and 14B in position to form a bottom 14 of container 17. Thus, the assembly comprising the liner and shell is then inserted in the bottom cover as shown in Figure 4 and an adhesive tape member 46 laterally passed around the junction between the two to retain the two in position.

When it is desired to dispense liquid, the tape 46 is severed, the cover 40 removed, the tape 44 broken, hose 16 extended and end 33 removed.

In Figures 6, 7 and 8 is shown a modified form of the invention in which the tops of two adjacent walls 11 are provided with severance score lines 50 uniting at a corner and each extending inwardly in cooperation with a vertical severance score line 51 which in turn cooperates with a scored fold line 52. Thus, by engagement with the fingers, the corner so formed may be severed along lines 50 and 51 and folded from the position of Figure 6 to the position of Figure 7, a triangular end 35 grasped and extended from the box as shown in Figure 7, the extreme tip 53 thereof cut-off and the liquid poured from the top of the container 21 as shown in Figure 8. This may be done when the assembly is in the position of Figure, 4, or where the bottom cover 40 has been removed as shown in Figure 1.

In Figures 9 and 10 there is shown a modification of this invention in which the shell 17A is modified to have the walls 'of its exterior ply terminating at 60. In this instance, the walls of the cap 40A extend upwardly and into abutment therewith, and comprise an extension thereof. Thus, instead of there being a two ply shell 17 with a cap placed thereover forming a third ply for the bottom thereof, the cap structure 40A and the shell 17A cooperate to provide two plies for the shell (with spaced bottoms) and when the cap 40A is removed there is one less ply for shell 17A throughout that portion normally occupied by the cap. This permits the container 10 to present a relatively unbroken exterior surface with the top edge of the side Walls of the cap and the bottom edge of the sidewalls of the shell in abutting juxtaposition. Positioned over the juncture is a tape 61 having arip cord 62 provided with a free end 63. Thus, end 63 may be grasped, the cord pulled in counterclockwise direction with reference to Figure 10, severing the tape' 6 and releasing the cap 40A from shell 17A.

In Figures 11 and 12 is shown a modified form of cap 40B in' which the cap is provided with severance score lines. joining at thecorner and connected to vertical severance score lines 72 and score lines 73. In Figure 11, the score lines have been indicated on the blank 40B forming the cap 40B. Thus, it will be seen that a corner of the cap 403 may be severed along lines 70, 72 and 73 thus removing a small portion of the vertical walls adjacent the corner and a portion of bottom flap 74 and cooperating bottom flap 75 so that the central recess 42 provided by spacers 41 is exposed.

In Figures 13 and 14 is shown a modified form of bottom cap 40C in which the bottom cap is provided with severance score lines 86 located on the blank 40C of Figure 13 as shown.

When the blank 40C is folded to form the bottom cap 40C of Figure 13 the flaps and 91 are folded into opposed relationship and flaps 92 and 93 folded thereover and secured thereto, or vice versa. In either instance the cooperation of the score lines 80-86 provides a circular scored portion defined by line 86, positioned as shown in Figure 13 which may be engaged by a thumb and ripped downwardly to the bottom of the box, and then an elongated tab or flap portion in the two plies of the bottom formed by the cooperation of flaps 90 and 91, 92 and 93 which may likewise be severed and a rec tangular portion formed by lines 81 and 82 positioned on the opposite wall of the cover from the position .of scored portion 86 which also may be severed.

Thus, by removing the scored portions the center recess 42'is exposed'permitting access to thetube 16.

In the'modifications of'Figures 1l-l4'it isof course preferable to have the cap 40B or- 40C integral with the outer shell since there is then nonecessity forremoving the entire cap to expose the dispensing means-but exposure is provided by removing only the scored portion of the cap. Thus, such modifications would look in cross-section as the structure-of Figure 9 except that the outer ply of'the shell would" not be severed, the cap and outer ply of the shell would be integral and there would be no need for tape 61 of cord 62.

The outer shell or outer container is preferably formed from ablank erected'to a rectangular prism as shown, in the nature of a box, but of course, it need not be formed from a blank and could be formed as shown without ever having been a blank. It is conventional, when corrugated boxes or chip board boxesare used to provide such blanked construction because of facility in shipment, storage, etc. and the blank is erected into the box when desired. Preferable materials are corrugated board, chip board' or the like, although of course other materials may be used within the spiritandscope of this invention.

The liner should comprise a fluid tight container and is usually in the form of a fiat folded bag, the top of the bag being sealed by heat or adhesive after fluid is introduced into the bag. It is preferred to have the bag thermoplastic so that itmay be heat-sealed for the substantially complete exclusion of atmosphere,. and flexible so that as fluid is withdrawn through the tube the bag will collapse and an air vent is not needed; Synthetic resinous material such as polyethylene hasbeen found superior'for this purpose. The liner material must of course be relatively chemically inert, not subjectto attack by the fluids contained therein. A variety of suitablematerials may be used for the liner and among these, the following.

The liner should comprise a scalable, preferably heatsealable, thin, smooth, tough, pliable, membranous, fluid tight film which is relatively inert and free from chemical attack by the liquids contained. A superior material having these characteristics is polyethylene. However, other materials available for such use are such materials as Cry-O-Rap, butadiene-acrylonitrile copolymer, manufactured by the Dewey & Almy Chemical Company; moisture resistant cellophanes, that is, regenerated cellulose sheets coated with lacquers or the like to improve their moisture resistance; vinyl chloride-vinylidene chloride copolymers; plasticized rubber hydrochloride which is readily sealed by heat and is available in the form of transparent sheets and under the trademark Pliofilm from the Goodyear Tire & Rubber Company; thermoplastic resins produced by the polymerization of vinylidene chloride alone or with other monomers under the trademark Saran by Dow Chemical; plasticized vinyl chloride-vinyl acetate copolymers available from many manufacturers; butadiene-styrene copolymers; and many others. Polyethylene film has been found superior.

The vent is preferably of the 'same material as the liner, and in the preferred embodiment comprises polyethylene, slightly more rigid than the polyethylene of the liner so that the flange may be heat-sealed to the liner. However, likewise, the vent may be of other materials as explained with reference to the liner and adhesively secured to the liner if desired.

The spacers are usually secured to the cover, although may be likewise secured to the spaced bottom of the inner container if desired. They may be constructed of any suitable material, usually several plies of corrugated board.

Thus, it will be seen that this invention provides a new and useful fluid tight container in which a flexible, relatively inert liner, preferably of thermoplastic synthetic resinous material, has secured thereto a vent, preferably heat-sealed to the liner, which has an elongated flexible conduit. The liner is positioned within the outer shell which confines and shapes itsconfiguration; the ventpositioned in a holeirr theshell-and the flexible conduit secured to the bottom of'the-shell which is spaced from a false bottom of the: shell, the false-bottom being provided, either by a removable cover or by' a portion of the shell itself.
