These arrangements include a traditional gable top formation, a closed-end, flat-top formation with ends tucked in for stacking, and a handle insertable into an opposing flap, a closed-end, flat-top formation with ends tucked into end walls and an exposed handle, and a closed carton with end flaps tucked into end walls in flat-top formation with handle flap inserted into an opposing flap for stacking. The carton can also include internal fold-flap auto-bottom features.
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/623,767, filed Oct. 28, 2004, the entire contents of this application being hereby incorporated by reference as if repeated in its entirety.
FIELD OF THE INVENTIONThe present invention generally relates to cartons for holding and packaging articles. More specifically, the present invention relates to cartons with multiple closure formations.
BACKGROUNDSeveral formations for enclosing cartons have been used in the past. These formations have been used in various applications, ranging from gift-wrapping boxes to containers for hazardous waste products. However, such prior cartons typically include only one possible folding arrangement. What is needed is a carton that incorporates multiple combinations of closure arrangements capable of being used in several applications.
SUMMARYThe present invention generally relates to a carton with multiple closure formations, including combinations of closure features that allow the carton to be formed in different enclosed arrangements. These arrangements combine, for example, a traditional gable top formation, a closed-end, flat-top formation with ends tucked in for stacking and a handle insertable into an opposing flap, a closed-end, flat-top formation with ends tucked into end walls and an exposed handle, and closed with end flaps tucked into end walls in flat-top formation with handle flap and inserted into opposing flap for stacking. The present carton can also be combined with internal fold-flap auto-bottom features.
As discussed herein, the present invention includes carton blanks that are foldable and/or closable into a number of different orientations to provide enclosed cartons of varying shapes, sizes, and orientations. Specifically, in one embodiment, the enclosure forms a closed-end traditional gable top formation. In another embodiment, the enclosed carton forms a closed-end, flat-top formation with ends tucked in for stacking and with a handle inserted into the internal carton cavity below the opposing handle flap. In yet another embodiment, the closed carton forms a closed-end, flat-top carton with end flaps folded outward and tucked into end walls with the handles exposed for easy carrying. In still another embodiment, the carton blank forms a closed carton with end flaps folded outwardly and tucked into end walls in a flat-top formation with a handle flap inserted into opposing flaps for easy stacking. These and other embodiments generally can be configured in any size carton, e.g. 5 pound, 10 pound, or larger barn-type cartons. The closure formations as detailed above, and combinations of the features of these closures, can be used to form a variety of other, similar designs of carton blank arrangements. The present carton blanks alternatively can include additional folding orientations and/or to modify the features and/or folding requirements of each closure formation for the enclosed cartons.
BRIEF DESCRIPTION OF THE DRAWINGS
For a more complete understanding of the present invention, reference should be made to the following detailed description and accompanying drawings, wherein like reference numerals designate corresponding parts throughout the figures. The invention also includes carton blanks, such as paperboard blanks, which are cut to a specific shape, and creased, scored, cut, or perforated in specific areas. The carton blanks define elongate panels between the creases or fold lines, and include flaps at respective ends of the panels. The blanks form cartons when fully assembled, so that when generally all flaps are closed, the assembled cartons have a series of sidewalls, e.g. four side walls, one or more top panels, one or more top side panels, and a bottom. For ease of nomenclature, the lines of folding, perforation, creasing, scoring, or other separation between panels are referred to herein generally as fold lines. In several places herein, these fold lines are shown in the figures as a series of non-continuous cuts interspersed by nicks. This shorthand is not intended to constitute the composition of the fold lines or of only fold lines and is intended to encompass any number or arrangement of spaces, nicks, cuts, creases, scores, cut scores, solid scores, other inclusions or spaced areas, or any combinations of these. For example, the fold lines could include substantially continuous fold lines as desired (not shown).
To facilitate understanding and explanation of the blanks and cartons formed therefrom, the elements and numerals described herein utilize the terms “upper,” “lower,” “top,” “bottom,” “front,” “back,” “north” “south,” “east,” and “west” to distinguish portions of the carton and of the blank. These conventions are included merely for ease of explanation and understanding of the present description, however, and should not be limiting in any manner. The descriptions of the panels and the elements as “upper,” “lower,” etc., also can be referred to as “first,” “second,” etc.
