Application December 22, 1934, Serial No. 758,820

17 Claims.

This invention relates to packaging containers; and has been made with the idea of providing an improved simple pouring container of closable nature, such container particularly valuable for packaging cereal flakes, powders for various purposes, flour, meal, coffee, tea, sugar, salt, soap flakes and other products which are fluent because ground, granulated, pulverized or otherwise naturally or artificially broken up or free flowing in non-liquid condition, although, of course, the use of the invention is not to be thus limited.

The invention aims to provide a novel and improved packaging container, of low weight and cost, which can be easily and permanently sealed where packed yet by a seal of such nature that the same can be easily broken by the consumer; which includes a packaging wall component released for the first time to act as an element instantaneously adjustable to form a pouring spout on thus breaking the seal; and which includes means for conveniently yet securely temporarily rescaling the package at the break in.

the seal following readjustment of said well component to its original condition.

In an approved form of container according to the invention, the same at an upper corner thereof is formed to include three wall portions,

two of which are opposite side wall portions mutually upwardly converged toward a ridge or crest line on the container where the same is to be sealed after filling, and the third of which is and reversed to extend beyond the container to form a perfect pouring spout. Inasmuch as said fiuting in its original condition presents an outwardly opening pocket the top of which is coextensive with the length of the crest line to be broken to open the package, very conveniently a knife can be inserted into said pocket atthe top of the latter and then thrust upwardly through the crest line to break the same exactly as required; which is why, for one reason, such an above said fiuting, the latter can be drawn out easily severable material as paper or cardboard is preferred for the making of the container where the sealing strip is a flap integral with a wall thereof.

In combination with the features aforesaid, the container also includes a closing means for the severed part-of the seal which is in the nature of a spring-metal fitment or equivalent, preferably in the form of a U-shaped clip pivotally secured to the top of the container near the crest line thereof and adjacent to the inner end of the fluting when extended inwardly of the container. Then this clip when swung up above its pivotal mounting can be cleared away from the part of the crest line to be severed, with such mounting acting to prevent an unnecessarily extensive severing. Following a reversal of the fluting to form the pouring spout aforesaid, and a dispensing of a part of the contents of the container, and then a restoration of such fiuting to its normal condition, the clip is ready to be swung down to straddle the marginal portions of the container on both sides of the severed length of the crest line and resiliently grip these marginal portions for again closing the container securely but with the latter now in condition to be readily reopenedwlthout further mutilation of any part for reestablishment and another use of the pouring spout.

The invention will be more clearly understood, and the various objects and advantages thereof fully appreciated, from the following description of a now preferred embodiment of the invention illustratively shownln the accompanying drawings, in which Fig. 1 is a fragmentary perspective view showing a corner of a container being folded together to form the fluting aforesaid in an end wall portion, with one of the side wall portions carrying a sealing strip as an integral flap in readiness to be folded over a crest line on the container running away from such corner to seal the package;

Fig. 2 is a fragmentary top plan view of the container after the folding procedure shown in Fig. 1 has been completed to establish said crest line, and after the flap has been bent over the same and secured in place to seal the packagesuch flap, however, being illustrated as partially broken away to show clearlyv the inwardly directed fluting of the end wall now trapped within such seal;

Fig. 3 is a fragmentary side elevation, showing the container sealed by said flap, and showing the clip aforesaid'in full lines in normal position and in broken lines swung up toclear away from the part of the seal to be severed by a consumer to adapt said fluting to be transformed temporarily into a pouring spout;

Fig. 4 is a view similar to Fig. 1, showing the seal severed, and the pouring spout established;

Fig. 5 is a top view of a modified form of container with the top closed;

Fig. 6 is a fragmentary side elevation of Fig. 5 looking in the direction of the arrow I;

Fig. 7 is a fragmentary perspective view showing the pouring spout established;

Fig. 8 is a plan view of Fig. 7;

Fig. 9 is a fragmentary side view of Fig. 8;

Fig. 10 is a fragmented perspective view of the container, in the act of closing down the sealing flaps; and

Fig. 11 is a layout of the blank of Fig. 5, in fragmentary form, illustrating the scores of the reseal end of the container.

Similar reference'characters refer to similar parts throughout the several views of the drawings. I

Referring to Figs. lto 4 in detail, the container end or corner illustrated includes a pair of opposite side walls the upper portions A and B of which will for convenience hereinafter be called the side walls, and a connecting end wall the upper portion C of which will for convenience hereinafter be called the end wall.

Said end wall C has a central vertical fold D extending from its top edge downwardly for a short distance, so that when the side walls A and B are further mutually upwardly converged than as shown in Fig. 1, and to extent to bring their upper margins close together along the top of the container, as shown in Fig. 2, the portions C and C" of the end wall on opposite sides of said fold and somewhat below the same will form the inwardly directed fluting aforesaid, and such a fluting now completely collapsed at its top, as also shown in Fig. 2, with the general contour of such fluting side-elevationally of the container substantially as indicated by the broken line D of Fig. 3.

Assuming that the container is now filled, a flap F shown as constituting an integral extension at the top of.side wall A is folded over the crest line G now established by the parts being brought together as last described, and extended down over the upper marginal portion of said Wall B, and there secured permanently in place, as by a strong glue. The parts are now assembled as shown in Fig. 2,'but with the seal formed by the flap F extended not only the required distance along the top of the container to the right of the showing of Fig. 2 to completely seal the container, but also to the left in Fig. 2 all the way over the inwardly directed fluting C'-C", as indicated by the dot and dash line F of Fig. 2. This results in tucking the top of the fluting tightly within the top seam thereby established along said crest line and effectually and tightly sealing the container all along said seam, especially if, as in some cases may be desirable, said fluting at its top is given an application of hot wax or other suitable material. As will be understood, the thus tucked-in fluting will present an inwardly directed outwardly opening pocket; such pocket being deepest lengthwisely of the container just below the crest line G.

Flap F as shown carries a printing or other indicium at H, so located as to lie and be exposed along the crest line G when the flap is secured in place to make the aforesaid top seam, and of such a length as to extend over this upper corner of the container to a point adjacent to the inner end of the top of the pocket last-mentioned; to constitute a guide to the consumer in breaking the temporary severable seal portion, as for instance by inserting a kitchen knifeinto said pocket to the depth permitted by the top thereof and then making an upcut with said knife along the crest line G.

When the crest line is thus or otherwise broken over the length of indicium H, the fluting is freed for pull-out reversal to arrange the end wall portions C and C" as shown in Fig. 4 and thereby form a pouring spout as illustrated. To facilitate such pull-out, this fluting is shown as provided with a device here comprising a thin cord or string J knotted at J and projecting through the end wall C near the fold D.

A permanent movable auxiliary seal or closure for acting in a secure and tight manner relative to the severed part of the top seal of the containen along crest line G, after a restoration of the fluting to its normal condition following a dispensing of the contents of the container by the aid of such fluting when arranged as a pouring spout as aforesaid, is shown as being in the form of a U-shaped spring metal clip K pivotally mounted on the top of the container by having one end thereof secured by a metallic rivet L to' the top seam along the crest line G at a point such that when the clip is swung up to the broken line position K in Fig. 3 the said seam can be severed along the length of-indicium H as above described with such rivet acting as a limiting means to prevent too extended a severing of said seam. There may be a considerable number of dispensings of the contents of the container before the latter is emptied, and in preparation for each of these the clip is swung up as just stated, and the fluting is reversed to form the pouring spout as shown in Fig. 5. Upon the completion of each of these dispensings, said fluting is again reversed to be returned to its normal condition as shown in Fig. 2; and then, with the upper marginal portions of the container below the indicium H held together, the clip K is swung down as shown in Fig. 3, to straddle such marginal portions and securely and tightly temporarily close the container.

The modified form of container shown in Figs. 5 to 10 inclusive, is, in many respects similar to that shown in Figs. 1 to 4, with the exception that in Figs. 5 to 10, the carton shown has no crest, and is so developed as to create a carton of complete rectangular contour, with a flat top, but is made and shipped in fiat condition.

The establishment of the pouring spout is accomplished in the same manner, by fluting, as in score lines S.

One or both end edges of the blank are provided with end closing flaps B, C, F and C'. Minor flap B is provided with a triangular portion M, scored from B by a diagonal score line M and traversed by score line S being thus scored from its adjacent minor flap C'.

All of the end closing flaps herein are scored from the body panels by a common score line R.

Minor flap C' is provided with two adjacent triangular sub-portions C and 0' these .latter being scored from flap C by divergent diagonal score lines cc.

Major cover flap AF is provided with a triangular flap F'B' at one of its sides adjacent minor fiap C, above, said flap .F--B being scored from A-F by two divergent triangular score lines F and B. The triangular flap F is traversed centrally by a weakening perforated line B", and the triangular sub-flap B is scored from its adjacent sub-flap C by the extension of body score line S.

The opposite side of major cover flap A--F is scored by an extension of body score line S from a minor triangular sub-flap C, which in turn is diagonally scored from minor flap C' by a score line 0. Minor flap C is also provided with a triangular sub-flap C" scored therefrom by diagonal score line 0. This latter flap C with its sub-flaps is identical with the other flap C in its structure, and when the carton is erected to its rectangular assembly, coacts, oppositely to the other minor flap C', to close the carton end, as will now be described in detail.

After the gluing of the glue lap Q to the end edge of panel M, the carton body is opened and the scored carton end closing members are broken on their score lines, as in Fig. 10, and the two triangular flaps C' are pushed inwardly towards each other, dragging with them the associate sub-flaps C, C, these, in turn, drawing the minor end flap B and the major closing flap A--F downwardly, as partially indicated in Fig. 10. Upon complete closure, cover flap A-F, as in Figs. 5 and 6, with a touch of glue on the F section thereof, covers all of the inturned flaps, and it then appears as in Fig. 5, wherein is shown the scored diagonal flaps F and B with the perforated weakened line B", exposed for manipulation for opening and reclosing.

As in the perspective view, Fig. '7, the weakened lineB" is broken and by bending the triangular flaps F and B' upwardly on their score lines F" and B", the fiuting formed by the flaps C'C'C' is exposed. As in Fig. 2, the inner triangular end formed in the flute by the converging ends of the flaps C"'C'C is then pulled outwardly leaving the spout thus formed in open outwardly extending position, shown also in Figs. 8 and 9. Thus the contents X of the package, Fig. 8 are exposed for pouring.

To reclose the spout the outer end thereof is pushed backwardly into the original fluted position, and the cover flaps F and B snap back to approximately their original positions and the contents of the carton are thereby protected from debris.

When the carton blank of Fig. 11 is folded on one of its score lines S, between body panels N and O, the glue lap Q is bent on its scored line S and glued to the side edge of panel M, the carton is then in flat condition and is so shipped to the user who erects the carton, fills and seals it.

It will be noted that the pouring spout herein is created by the novel scoring and coordination of the same style and number of closing flaps customarily used on cartons of this type, and is thus constructed without the use of additional parts. .It will further be noted thatall of the end closing flaps are continuous with one an- 1 other and are integral with one another.

It will further be noted that in the modified form of Figs. 5 to 10, the major flap F-A, when glued, forms the permanent seal, and the,

said temporary seal is broken to form a pouring spout substantially as described.
