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. Although a variety of such cartons are known, there is always a desire for a carton that provides a new balance of properties.
One aspect of the present invention is the provision of a carton from which contents may be poured. The carton may include 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, and a second end flap foldably connected to a second panel of the plurality of panels. The first and second end flaps may be in an overlapping relationship with respect to one another so that they at least partially form an end panel that typically closes an end of the carton. The end panel may cooperate with at least one of the plurality of panels to form a corner of the carton. The first end flap may define 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 may include an obstructing portion that at least indirectly obstructs the opening. The second end flap may be 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 strip) of the second end flap.
The carton may further include 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 third end flap may include an obstructing portion that at least indirectly obstructs the opening. The third end flap may be 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.
In accordance with one aspect of the present invention, a carton may include a plurality of panels that extends around and defines an interior of the carton, with a first panel of the plurality of panels being foldably connected to second and third panels of the plurality of panels by respective fold lines. An end panel of the carton typically closes an end of the carton and cooperates with at least the first panel to form a corner of the carton. The end panel is adapted for at least partially defining an opening proximate the corner of the carton. 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.
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.
In accordance with one aspect of the present invention, a carton blank includes 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.
Other aspects and advantages of the present invention will become apparent from the following.
Having described some aspects of the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
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.
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.
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
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.
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 tom completely away from the carton 130.
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
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.
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.

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
In accordance with the first embodiment and as shown in
Referring now to
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.
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.
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.
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.
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 spirit and scope of the invention as set forth in the following claims.
