Application September 25, 1939,'Serial No. 296,354 sciaims. (01. 229-1) Thisinvention relates to the art of packagin commodities. and more particularly to dispensing packages. I x

An Object of this invention'is to provide a package embodying a flexible inner container of sheet material and a structurally strong outer or carrier receptacle protecting the relatively fragile inner container and characterized by extremely simple means manually operable to expose a dispensing portion of the inner container which is adapted to project through an opening in the outer receptaclenormally closed by said means, so that the dispensing portion can function as a highly eflicient pouring spout.

Another object of the invention is toprovide a dispensing package wherein the closure bf the outer receptacle, while adequately protected against accidental disturbing, is readily openable by a simple manipulation to leave a generally triangular opening in the receptacle, through which is exposed a generally triangular flap of the inner container normally folded flat between the container and receptacle at the closure of the latter, for manipulation of the flat through the opening to a pouring position wherein the flap can also co-act with the edges of the opening in being supported thereby in spout formation'for pouring the contents of the inner container therefrom.

With these and other objects in view, the invention resides in the combinations and arrangements of elements as set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is aperspective view of the sealed package; f Figure 2 is a fragmentary vertical sectional view of the upper portion of the package; Figure 3 is a fragmentary perspective view of the package with the closure thereof opened to expose the dispensing portion ofthe inner container; V Figure 4 is a view similar to Figure 3 and showing the dispensing portion of the inner container the pouring spout; 1

the drawings and parinclusi've, this form of an inner container C and an outer or carrier receptacle R, the inner flexible sheet maas chlorinated package with the chored together at Referring specifically to ticularly to Figures 1 to 6,

terial which is impervious, such rubber or Pliofilm, both of which are capable of being hermetically sealed by the application of heat and pressure to preserve The inner container is folded from a fiat blank into a rectangular envelope which is filled through one open end subsequently closed by being folded upon itself to include hollow triangular flaps l0 suitably sealed along their edges.

The outer receptacle R is constructed of chip board or other cheap sheet material having the requisite structural strength to adequately protect the inner container C. against injury. The receptacle is formed from the blank shown in Figure 6, the blank being scored to provide four rectangular panels ll having [2' and I3 at their ends, and one having a side flap M to which a suitable adhesive is applied to secure the side flap to the inner side of that one having the free side edge so as to enable the blank to be opened to receptacle formation. v

At one end, one of the panels II is perforated alongtwo short lines l5 adjacent and parallel to the side edges of the panel, and these perforations are continued in two converging-straight lines ii to an apex IL. This panel is further perforated from the lines l5 along the juncture of said one end flap H as indicated tive view of the inner their contents.

rectangular flaps flaps are folded and secured together bya suitable adhesive (as shown in Figure 1), a fingerengageable portion or piece 207wil1 be formed along the length of the slit I9.

The amount" of lateral offset of the slit l9 from the juncture of the panel H into the flap I2 is such that the height of the resulting piece 20 will, in the closed position of the end flaps, not exceed the thickness of the sheet stock from which the receptacle is made. Thus the piece 20 will not interfere with the stacking of a number of the receptacles and will not be inadvertently disl6 and I8, and the slit l9 co-act to define a generally triangular closure 22 having the piece 20, and which closure is at that end of the receptacle R. through which the'filled container C is inserted into the receptacle.

It will be noted that the container C is inserted into the receptacle R. with the flaps III of the container folded fiat between the container and receptacle, and with one of these flaps directly opposite the closure 22 as shown in Figure 2.

Furthermore the flaps l correspond in their gen eral outlineto that of the closure 22 and are slightly less in size than the latter. Thus, upon tearing off the closure along the lines l5, l6 and I8 by pulling upon the piece 20, said one of the flaps III will be exposed in the resulting opening 23 in the panel H and can readily be swung outwardly through the opening to the pouring position shown in broken lines in Figure 3 to function as a pouring spout P, (Figure 4).

By now severing the sealed tip end of the flap H) from the remainder of the flap along the line 24, fluid contents of the container can be conveniently poured therefrom in easily controlled quantities.

The converging side edges of the opening 23 are adapted to co-act with the pouring spout and with the body of the container in limiting the extent to which the spout can be expanded by the weight of the contents of the container during the pouring operation, and thus efiectively confine the spout against rupture as well as support the spout in pouring position.

I It will thus be manifest that by the above described correlation of the closure 22 and the flap It, the opening 23 resulting from the removal of the closure, co-acts with the flap III in insuring that the latter will be maintained in the shape of a highly efiicient pouring spout irrespective of the weight of the contents of the container tending to deform the spout. p

Reference will now be had to Figures '7 to 10, inclusive, which illustrate a modified form of closure 220; for the outer'receptacle R.

In this form of the invention the outer'receptacle R is also constructed of chipboard or other cheap strong material from the blank shown in Figure 10, which is scored to provide the four tions continue in two converging straight lines.

. intermediate slit l9a.

The container C is inserted into the receptacle R with the fiaps l0a of the container folded fiat between the container and receptacle, and with one of the flaps directly opposite the closure 22a as shown in Figure 9.

. manner previously described.

In the use of the package for heavy liquids such as lubricating oils, the end walls of the inner container C are preferably secured to the flaps l2 of the outer receptacle R by means of a suitable adhesive. As shown in Figures 11 and 12, this adhesive can be applied along those edges of the inner container from which the flaps Ill project, in the form of strips 26 extending .to the corners 21 of the container, or can be applied tothe end walls or to the flaps I2 to cover the entire area thereof.

The adhesive efiectively anchors the inner container in the outer receptacle against movement relatively thereto at the corners 21 so that surging of'the heavy liquid contents of the inner container resulting from handling of the package cannot work the corners 21 back and forth to weaken same and cause leakage of the contents. It will be appreciated that surging of. the liquid content will alternately produce suction and pressure at the corners 21, which would ultimately fracture the inner container at the junction of the fold lines, were the inner container entirely loosev in the outer receptacle.

It will be manifest that this feature of the invention greatly enlarges the range of liquid products which can be marketed in the package, and enables heavy lubricating oils for automotive use to be supplied to the consumer in quart and other small sizes in a very inexpensive and structurally strong package capable of being opened to conveniently dispense the contents with the utmost ease and dispatch.
