v (Cl. 229-17) 9 Claims.

This invention relates to a package and to a carton for producing the package.

The invention has for an object to provide a package comprising a lled carton having a novel and highly eflicient top closure adapted to be opened in a manner such as to form a novel pouring spout facilitating the discharge of the contents of the carton and also adapted to be thereafter reclosed in a novel manner.

With this general object in view and such others as may hereinafter appear, the invention consists in the package and carton hereinafter' described and particularly defined in the claim..-` at the end of this specification.

In the drawings illustrating the preferred embodiment of the invention, Fig. 1 illustrates a blank from which the present carton may be formed; Fig. 2 is a 'perspective view of the top of the carton illustrating the latter in its open condition; Fig. 3 is a similar view showing the manner in which the top of the carton is initially closed; Fig. 4 is a plan view of the carton showing the flaps disposed in position for the application of adhesive for sealing the carton; Fig. 5 is a perspective view of the package embodying a filled, closed and sealed carton provided with a wrapper, the latter being partially broken away to reveal an extended portion of the top closure for use in initially opening the carton; Figs. 6, 7 and 8 are perspective views showing successive steps in opening the carton; Fig. 3 showing the carton completely opened to form a pouring spout; and, Fig. 9 is a perspective view showing the top closure in its reclosed condition.

In general, the invention contemplates a package comprising a filled carton having a novel top closure whose construction is such as to enable one end of the top closure to be opened to form a pouring spout for convenience in dispensing the commodity from within the carton, and in which provision is made for enabling the c arton to be reclosed in novel and simple manner.

In the preferred form of the invention, one of the end flaps of the carton is formed integrally with an adjacent side ap, the latter being preferably scored to permit the connected side and end naps to be folded together down into top closing position to form a bellows-like fold in one of the naps. Thus, when the pouring end of the top closure is opened, the integral side and end .flaps form at the corner between the same a V- adjacent the pouring end so that the naps may be easily torn andl separated from the remainder of the carton. In order to provide a convenient` and efficient means of reclosing the carton, a perforated portion of an underlying ap of the -carton may be offset with respect to an overlying perforated portion, so that after the carton has been initially opened, the separated flaps forming the. pouring spout may be closed and l tucked in under the remaining portion of the top closure as will be hereinafter described.

Referring now to the drawings, Fig, 1 illustrates a blank of carton forming material consisting of a body portion comprising the end and side wall panels I0, l2,`scored in the usual manner, and provided with bottom flaps lll, I6 of any usual or preferred form extending from the body portion of the carton. The carton is also provided with the usual longitudinal tab I'i for adhesively securing the body portion in its assembled form.

In accordance with the present invention, the top closing flaps are constructed and folded in a manner such as Ito provide a pouring spout at one end of the carton when the latter is opened as shown in Fig. 8, and, as best shown in Figs. 1 and 2, the top closing fiaps'comprise an end flap I8, a side flap 20 provided with perforated or weakened lines 22, 24, and a connected end and side flap member comprising an end portion 26 and a side portion 28 provided with score lines 30, 32 arranged to form a bellows fold when the portions 26, 28 are folded along the score lines 30, 32 and down into top closing position. A row of perforations 34 is also provided in the side portion 28 of the connected aps.

As best shown in Fig. 3, the sequence in which the flaps are initially closed to form the top closure is as follows. The connected end and side flap member is first folded down by folding in the side flap portion 28 and the end portion 26 to' thereto, the exposed surfaces of the flap I8 and vportion 2E being also provided with adhesive at the same time. As shown in Fig. 5, the completely sealed package .or carton may, in some instances, be provided with an outer wrapper 40.

From the description thus far, it will be observed that in the assembled package or carton. the bellows fold portion of the integral flap member is free of adhesive andthat the underlying row of perforations 34 in the flap portion 28 extends transversely of the top of the carton adadjacent one end of the bellows fold, as best shown in Figs. 3 and 4.- -It will also be observed that the portion 2| of the last folded flap as defined by the perforated lines 22, 24, is adhesively secured to the top of the end flap portion 26 and forms an integral part thereof in the closed carton. It will also be noted that the transverse row of perforations 24 in the overlying side flap 20 is offset with respect to the underlying row of perforations 34 so that the upper panel 2|, when separated from the panel 20, will be slightly longer than the underlying portion 26 and the connected portion forming the bellows fold, for a purpose to be hereinafter described.

Referring now to Figs. to 8, in order to open the carton to expose the pouring spout, the top closure is first torn along the upper perforated line 24 by lifting upwardly against the bellows folded portion as shown in Figs. 5 and 6 to separate the panel portion 2| from the side flap 20, the remaining portion of the latter being retained in its initially sealed condition. This opsofas to provide a convenient projection 42 in the closed carton by which the flaps may be grasped by the thumb and forenger to initiate the tearing operation. As illustrated in Figs. 1 and 4, the folded edge of the bellows fold is caused to project beyond the edge of the carton, as shown, by scoring the folding line 30 slightly off the perpendicular so that the angle defined by the score line 30 and the top score line 44 of the flap portion 26 will be slightly more than 90. Thus, when the flap portion 26 is subsequently folded down, the folded edge 3E!A will project outwardly beyond the edge of the carton, as clearly -shown in Fig. 4.

Upon separation'of the panel 2| as above described, the upraised flaps are grasped as shown in Fig. 6, and, upon further lifting movement in a diagonal direction toward the corner 45, kthe underlying perforated portion 34 of the flap 28 and the perforated edge 22 of the upper flap 20 are simultaneously ruptured whereupon the severed panels may be fully extended to form a V- shaped pouring spout, as illustrated in Figure 8.

It will be observed that upon opening the carton, the severed .edge 48 of the underlying flap 28 extends beyond the severed edge 5|! of the upper flap 20 in the remaining sealed portion of the carton, as a result of the offset relationship between the transverse perforated lines 34 and 24 as previously described, and that the severededge edge 52 of the detached panel 2| will extend beyond the edge 48 when the flaps are again folded downto reclose the carton. In order to retain While the preferred embodiment of the invention has been herein illustrated and described it will be understood that the invention may be embodied in other forms withinthe scope of the following claims.
