Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims benefit of U.S. Provisional Application No. 60/818,357, which is entitled "Carton With Pour Feature" and was filed on June 30, 2006.

BACKGROUND

[0002] The present invention generally relates to cartons and, more particularly, to cartons used for containing and dispensing (e.g., pouring) contents, such as foodstuffs or other dispensable products. A variety of such cartons are known. E.g. U.S. 2005/0274086 A1 discloses a packaging blank capable of forming a reclosable container comprising in one embodiment a front panel having opposing side panels, a rear panel connected to the front panel by the second side panel, a top panel connected to a top edge of the front panel, a bottom panel connected to a bottom edge of the front panel, and a pour spout flap connected to a top edge of the second side panel. Upon construction the packaging blank provides a reclosable container having an integral pour spout that is releasably securable to a portion of the top panel. In greater detail, this reference teaches a three-ply top panel structure at the pouring spout region, the innermost top flap comprising a pouring opening, the outermost top flap comprising a spout structure and a tear-off portion, and the intermediate top flap may comprise a detachable sealing tab which may be torn-off the remaining intermediate top flap along a perforation so as to expose the pouring opening in the innermost top flap.

[0003] The present invention aims at providing an improved carton with pouring features which provides a new balance of properties.

BRIEF SUMMARY OF SOME ASPECTS OF THE INVENTION

[0004] The object set out above is achieved by the carton defined in claim 1. Accordingly, one aspect of the present invention is the provision of a carton from which contents may be poured. The carton includes a plurality of panels that extends around and defines an interior of the carton, a first end flap foldably connected to a first panel of the plurality of panels, a second end flap foldably connected to a second panel of the plurality of panels, and a third end flap connected to a third panel of the plurality of panels, with the third end flap being part of the end panel. The first and second end flaps are in an overlapping relationship with respect to one another so that they at least partially form an end panel that closes an end of the carton. The end panel cooperates with at least one of the plurality of panels to form a corner of the carton. The first end flap defines an opening that substantially extends to the corner of the carton and is adapted for use in pouring contents from the carton. The second end flap includes an obstructing portion that at least indirectly obstructs the opening. The second end flap is adapted so that at least the obstructing portion can be moved away from the opening. The obstructing portion of the second end flap may be a tear-away portion (e.g., tear grip) of the second end flap.

[0005] The third end flap includes an obstructing portion that at least indirectly obstructs the opening. The third end flap is adapted so that at least the obstructing portion of the third end flap can be moved away from the opening. The third end flap may be positioned between the first and second end flaps while the carton is closed. The third end flap may be deformed to form a spout that is adjacent to the opening while the carton is open and its contents are being poured.

[0006] In accordance with one aspect of the present invention the first panel of the plurality of panels may be foldably connected to the second and third panels of the plurality of panels by respective fold lines. The carton is adapted so that the first panel and/or an associated end flap is for being deformed to at least partially form a pour spout that is proximate the opening. One or more lines of disruption (e.g., crease lines) may be provided for aiding in the formation of the spout. In accordance with one embodiment, at least a portion of the end panel may be adapted for bracing the second and third panels apart from one another while the spout is formed, with the bracing seeking to keep the spout from collapsing.

[0007] In accordance with one aspect of the present invention, a method of pouring contents from a carton includes partially opening at least an end panel of the carton so that the carton has an opening through which contents may be poured from the carton. A predetermined portion of the end panel remains substantially intact, so that the predetermined portion of the end panel closes a substantial portion of an end of the carton. The method further includes squeezing a predetermined portion of the carton. The carton may be adapted so that at least one portion of the carton deforms, in response to the squeezing, to form a spout that is proximate the opening. The carton being adapted may further comprise the predetermined portion of the end panel bracing panels of the carton apart from one another in a manner that restricts the spout from collapsing. The method further includes pouring contents from the carton by way of the opening and the spout. Optionally, the spout may automatically cease to be formed and the opening may be closed after the pouring.

[0008] A carton blank for forming the carton of the present invention may include a first panel, a second panel, a third panel, a first end flap having a first edge foldably connected to the first panel at a first fold line, and a second end flap having a first edge foldably connected to second panel at a second fold line that is substantially aligned with the first fold line. The third panel includes opposite first and second edges that are respectively foldably connected to the first and second panels. The first end flap includes opposite second and third edges. The first end flap may define a hole that is at least partially defined by the second edge of the first end flap. The second end flap includes opposite second and third edges. The second end flap may include a line of disruption that is proximate the second edge of the second end flap. The line of disruption at least partially defines a portion (e.g., tear strip) of the second end flap that is movable relative to a remainder of the second end flap, and the movable portion of the second end flap may include at least a portion of the second edge of the second end flap.

[0009] Other aspects and advantages of the present invention will become apparent from the following.

DETAILED DESCRIPTION OF SOME EMBODIMENTS OF THE INVENTION

[0011] Referring now in greater detail to the drawings, in which like numerals refer to like parts throughout the several views, it will be understood that an aspect of a first embodiment of the present invention generally relates to features for facilitating dispensing (e.g., pouring) from a carton. Features of the present invention can be used, for example, in cartons that contain articles or other products that are suitable for being poured. For example and not limitation, the articles can be particulate products such as rice, beans, sugar, and other pourable solid products, such as soaps and detergents.

[0012] Fig. 1 is a plan view of a first, exterior side of a blank 8 used to form a carton 130 (illustrated in Fig. 3) having a feature for pouring 100 according to a first embodiment of the invention. Figs. 2A, 2B, and 2C depict the blank 8 in partially erected configurations. Referring to Fig. 1, the blank 8 defines a longitudinal axis L, which extends in a longitudinal direction, and a transverse axis T, which extends in a traverse direction. The blank 8 includes a first side panel 10 foldably connected to a first end panel 20 at a first longitudinal fold line 21, a second side panel 30 foldably connected to the first end panel 20 at a second longitudinal fold line 31, and a second end panel 40 foldably connected to the second side panel 30 at a third longitudinal fold line 41. In the illustrated embodiment, the longitudinal fold lines 21, 31, 41 are generally parallel to longitudinal axis L. An adhesive flap 50 may be foldably connected to the first side panel 10 at a fourth longitudinal fold line 51 that is also generally parallel to longitudinal axis L.

[0013] For ease of understanding in this specification, the relative terms "bottom" and "top" may indicate orientations determined in relation to fully erected cartons. The first side panel 10 is foldably connected to a first side top flap 12 and a first side bottom flap 14. The first end panel 20 is also preferably foldably connected to a first end top flap 22 and a first end bottom flap 24, just as the second side panel 30 and the second end panel 40 may be foldably connected to their respective top flaps 32, 42 and their respective bottom flaps 34, 44.

[0014] The top flaps 12, 22, 32, 42 may extend along a first marginal area of the blank 8, and may be foldably connected to their respective panels along a first transverse fold line 62 extending generally parallel to transverse axis T. The bottom flaps 14, 24, 34, 44 may extend along a second or bottom marginal area of the blank 8, and may also be foldably connected to their respective panels along a second transverse fold line 64 also extending generally parallel to transverse axis T. The transverse fold lines 62, 64 may be straight or substantially straight fold lines, or may be offset at one or more locations to account for, for example, blank thickness. Each of the transverse fold lines 62, 64 may be characterized as being a plurality of fold lines that will typically be at least somewhat colinear while the blank 8 is in its flat configuration shown in Fig. 1.

[0015] According to one aspect of the first embodiment of the present invention, the carton blank 8 includes a feature for pouring 100 that typically includes an opening 102 (e.g., a hole adapted for having contents poured through) formed in the first side top flap 12, and the feature for pouring 100 optionally further includes a crease pattern 104 formed in first end panel 20 and/or the first end top flap 22. In accordance with the first embodiment, the opening 102 is a hole that extends through the first side top flap 12 and is substantially larger than a slit; and the opening 102 is centered along an edge of the first side top flap 12, and that edge can be characterized as defining the opening 102.

[0016] In accordance with the first embodiment, a portion (e.g., a movable obstructing portion) of the second side top flap 32 indirectly obstructs the opening 102, and the obstructing portion of the second side flap is a tear-away feature that may more specifically be in the form of a tear strip 110. The tear strip 110 is defined by a first line of disruption 112 (e.g., tear line) and a second line of disruption 114 (e.g., tear line) formed in the second side top flap 32. More specifically, the second tear line / second line of disruption 114 extends along, or more specifically is colinearly formed on, a portion of the transverse fold line 62. Differently configured obstructing portions (e.g., tear strips 110) of the second side flap 32 are also within the scope of the present invention. For example, the tear strip 110 may be modified so as to remain foldably attached, such that it is a flap that is foldably attached to the remainder of the second side top flap 32 (e.g., the line of disruption 112 may be a fold line rather than a tear line). Also, the tear strip 110 can have other than a strip-like shape, such that it can be more generally referred to as a tear-away portion, although it is not required that the tear strip 110 or other tear-away portion be torn completely away from the carton 130.

[0017] In the illustrated embodiment, the top flap 22 does not extend as far outwardly as the top flaps 12 and 32. Accordingly and while the blank 8 is in its flat configuration shown in Fig. 1, a portion of the top flap 12 (i.e., a portion of its edge that defines the opening 102) is in opposing face-to-face relation with a portion of the top flap 32 (i.e., a portion of its edge that is included in the tear strip 110 and extends parallel to the tear line / line of disruption 112.

[0018] In the illustrated embodiment, the crease pattern 104 includes an elongate line of disruption 106 (e.g., a crease line and/or score line) extending in the first side end panel 20 and the first end top flap 22 from an edge of the first end top flap 22 down to an end point 107. In accordance with the first embodiment, the line of disruption 106 is substantially colinear with the center of both the first side end panel 20 and the first end top flap 22. The line of disruption 106 can be characterized as being two separate, substantially colinear lines of disruption respectively in the first end panel 20 and the first end top flap 22. The first side end panel 20 further includes an inverted V-shaped line of disruption 108 (e.g., crease line and/or score line), which has two legs 109a, 109b, that is positioned with its vertex coincident with the end point 107 of the elongate line of disruption 106. The legs 109a, 109b terminate at their respective intersections with the first and second longitudinal fold lines 21, 31. The crease pattern 104 or any portion thereof may be omitted.

[0019] The first and second lines of disruption 112, 114 (e.g., tear lines) of the tear strip 110 may be continuous or substantially continuous breachable lines of disruption formed from, for example, scores, creases, cuts, gaps, perforations, offset cuts, or any combinations thereof. If cuts are used to form the first and second lines of disruption 112, 114, the cuts may be, for example, interrupted by breachable nicks. The elongate and V-shaped lines of disruption 106 and 108 (e.g., crease lines) may be any type of continuous or substantially continuous lines of disruption that will facilitate bending along the lines of disruption, such as scores, creases, offset cuts, perforations or combinations thereof.

[0020] Referring to Figs. 1 and 2A and very generally described, the carton 130 (Fig. 3) may be erected from the blank 8 by respectively folding the blank and gluing or otherwise adhering or attaching the adhesive flap 50 to the inner side (not shown) of the second end panel 40, so that the first side panel 10, first end panel 20, second side panel 30, and second end panel 40 form a generally tubular construct with open ends. Referring now to Fig. 2B, the partially assembled carton 130 has an open top end 132 and an open bottom end 134. The bottom end 134 may be closed, for example, by folding the bottom flaps 24 and 44 inward. The bottom flap 14 may then be folded inward and adhered to both of the bottom flaps 24 and 44. The bottom end 134 may then be completely secured by folding the bottom flap 34 inwardly and adhering the flaps 14 and 34 together. In this way, the bottom flaps 14, 24, 34, 44 together form the carton's bottom panel (not shown).

[0021] Turning now to Fig. 2C, the top end 132 of the carton 130 may be closed, for example, beginning with folding the flaps 12 and 42 inward, with the flap 42 typically being folded in first. Typically the inwardly folded flaps 12 and 42 are adhered to each other. The top flap 22 is then folded inward toward the top flap 12 so that the flap 22 covers (e.g., obstructs) the opening 102 (Fig. 1). That is and in accordance with the first embodiment of the present invention, a portion (e.g., an obstructing portion) of the first end top flap 22 obstructs the opening 102. In accordance with the first embodiment of the present invention, the obstructing portion of the first end top flap 22 is that portion that overlies the opening 102. Preferably, the flap 22 is not adhered to the flap 12; although the flap 22 may be releasably adhered to the flap 12 in an alternative embodiment. Finally, the top flap 32 is folded inwardly so that it covers the other top flaps 12, 22, 42 and so that the removable tear strip 110 covers the top flap 22 and indirectly obstructs the opening 102. The top flap 32 is adhered to the flap 12 (except that the tear strip 110 is typically not adhered, although the tear strip may be releasably adhered in an alternative embodiment), thereby completing formation of the carton's top end panel. That is and in accordance with the first embodiment of the present invention, when the carton 130 is closed as shown in Fig. 3, its top end panel is formed by the overlapping top end flaps 12, 22, 32, 42. The tear strip 110 can be characterized as an obstructing portion of the top flap 32 because the tear strip obstructs access to the flap 22 and the opening 102, as will be discussed in greater detail below.

[0022] Fig. 3 is a perspective view of the fully erected carton 130 formed from the blank 8 (illustrated in Fig. 1). When fully erected, the carton 130 of the first embodiment is a parallelepiped, but the blank 8 may be configured such that the resulting carton has another geometric shape, such as, for example, a triangular, hexagonal or octagonal prism. It should be understood that either the carton's top end 132 or the carton's bottom end 134 may be assembled first, leaving the other end open so that the contents of the carton 130 may be introduced into the container. Once fully filled, the open end may be assembled / closed, and the carton 130 will typically securely hold its contents until the opening 102 is uncovered to dispense the contents as described in further detail below in accordance with the first embodiment of the present invention. That is, an acceptable method of preparing for and subsequently pouring contents from the carton 130 is described in the following, in accordance with the first embodiment of the present invention.

[0023] After the carton 130 has been fully closed as discussed above, an acceptable process of preparing to pour contents from the carton 130 may begin with partially opening (e.g., partially dismantling) the top end 132 of the carton. For example and referring to Fig. 4, a user 2 may open the feature for pouring 100 by grasping an end 111 of the tear strip 110 located proximate to the first side panel 10. The user 2 may then pull on the tear strip 110 in the direction of arrow A so that the tear strip separates from the remainder of the top flap 32 along the first line of disruption 112. Referring to Fig. 5, the user 2 may fully remove tear strip 110 from the top flap 32 by tearing along the second line of disruption 114. The removed tear strip 110 no longer obstructs access to top flap 22 and opening 102 (Fig. 1), and the user 2 may manipulate the top flap 22 as described in detail below.

[0024] Referring now to Figs. 6 and 7, the user 2 may grasp and unfold the obstructing top flap 22 away from the top flap 12 in the direction of arrow B, thereby exposing the opening 102 (Fig. 7). In the illustrated embodiment, opposite side edges of the top flap 22 taper toward one another in a manner that facilitates the manually grasping of the opposite side edges of the top flap 22. As shown in Fig. 7, the remaining portion of the top end panel is substantially intact, with this substantially intact, remaining portion of the top panel including the remaining portion of the second side top flap 32, the first side top flap 12 and the top flap 42 (Fig. 1).

[0025] Turning now to Fig. 8, once top flap 22 is unfolded away from top flap 12, the user optionally may squeeze the carton 130 along the first and second longitudinal fold lines 21 and 31 as indicated by arrows C and D, so that the top flap 22 and first end panel 20 (Fig. 9) deform (e.g., bow outwardly) generally along the crease pattern 104 (Fig. 1) in the direction of arrow E. With particular reference to Fig. 9, deformation along the elongate line of disruption 106 and the V-shaped line of disruption 108 (Fig. 3) allows the top flap 22 and/or the first end panel 20 to act as a spout 162 that assists the user 2 in minimizing the risk of spillage when pouring the contents 4 out of the carton 130. In accordance with the first embodiment, the spout 162 is substantially formed from predetermined portion(s) of the fully erected blank 8, without requiring the addition of additional plies, layers, patches or the like to the blank 8. Fig. 9 is schematic because the contents 4 hidden from view in the carton 130 are schematically shown. As the user deforms the carton 130 along the crease pattern 104 in the direction of arrow E, the effective area of opening 102 expands and allows the carton's contents to pour out more easily.

[0026] In the first embodiment, the spout 162 may be most helpful when the opening 102 is positioned such that it extends substantially to a corner of the carton 130. In accordance with the first embodiment of the present invention and as best understood with reference to Figs. 4, 5 and 7, the corner of the carton 130 that the opening 102 extends substantially to is defined where the first end panel 20 meets the top end panel. In the configuration of Fig. 4, the top end panel is made up of the combination of the closed top flaps 12, 22, 32, 42 (Fig. 1), although the top end panel can be configured differently (e.g., see Fig. 7). As shown in Fig. 7 and in accordance with the first embodiment, the opening 102 is located at the subject corner.

[0027] In accordance with the first embodiment and as shown in Fig. 9, the remaining portion of the top end panel which is substantially intact (which in Fig. 9 includes the remaining portion of the second side top flap 32, the first side top flap 12 and the top flap 42(Fig. 1)) braces the first and second side panels 10, 30 apart from one another in a manner that aids in formation of the spout 162 by seeking to keep the spout from collapsing as may occur if the first and second side panels 10, 30 were to come into opposing face-to-face contact with one another. As shown in Fig. 9, the substantially intact, remaining portion of the top panel also closes a substantial portion of the top end of the carton 130 so as to limit the amount of contents 4 that can be simultaneously poured from the carton.

[0028] Referring now to Fig. 10, the feature for pouring 100 may be closed once the user 2 is finished dispensing the contents 4 (Fig. 9) from the carton 130, as will be described below in accordance with the first embodiment. After dispensing some of the contents 4 from the carton 130, the user releases any manually-applied "squeezing" pressure exerted on the first longitudinal fold line 21 (Fig. 1 and 2C) and second longitudinal fold line 31 and allows the material along the crease pattern 104 (Fig. 3) to substantially return to its normal, undeformed configuration (e.g., the spout 162 substantially ceases to be formed). That is and in accordance with the first embodiment, the carton 130 has sufficient resilience so that the spout 162 automatically substantially ceases to be formed in response to the ceasing of the squeezing (e.g., the carton 130 automatically substantially returns to the configuration shown in Fig. 7). The user 2 may then fold the first end top flap 22 inward in the direction of arrow F so that the flap 22 (e.g., an obstructing portion of the flap 22) covers or obstructs the opening 102 in a manner that seeks to prevent the contents 4 (Fig. 9) from spilling out of the carton 130. The user may releasably close the opening 102 by tucking an edge of the first end top flap 22 under the second side top flap 32 at the remaining portion of the first line of disruption 112 so that the previously "free" end of the first end top flap 22 is snuggly positioned between the first side top flap 12 and the second side top flap 32 as shown in Fig. 5, thus closing the carton until the next time the user desires to dispense the carton's contents.

[0029] It should be understood that the blank 8 can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blank may then be coated with a varnish to protect any information printed on the blank. The blank may also be coated with, for example, a moisture barrier, on either or both sides of the blank. In accordance with the above-described embodiments, the blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described above. The blank can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.

[0030] In accordance with the above-described embodiments of the present invention, a fold line and a crease line can be any substantially linear, although not necessarily straight, line of disruption or other form of weakening that facilitates folding or deformation therealong, respectively. More specifically, but not for the purpose of narrowing the scope of the present invention, fold lines and crease lines may comprise: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; or various combinations of these features. In situations where cutting is used to create a fold line or a crease line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the line to be a tear line.

[0031] In the present specification, a "panel" or "flap" need not be flat or otherwise planar. A "panel" or "flap" can, for example, comprise a plurality of interconnected generally flat or planar sections.

[0032] In the foregoing, panels and/or flaps are described as being respectively adhered, and this may be done with an adhesive material such as glue. The term "glue" is intended to encompass all manner of adhesives commonly used to secure carton panels in place. Also, adhesive connections can be replaced by or supplemented with other suitable connections.

[0033] It will be understood by those skilled in the art that while the present invention has been discussed above with reference to exemplary embodiments, various additions, modifications and changes can be made thereto without departing from the scope of the invention as set forth in the following claims.
