Abstract: A carton including a tubular structure defined by a top wall, a bottom wall, a first side wall, and a second side wall and a first end wall and a second end wall, each enclosing an open end of the tubular structure. The top wall includes a first chimney side panel and a second chimney side panel that are separable from one another. A first collapsible chimney end wall and a second collapsible chimney end wall, each being positioned adjacent one of the walls of carton, wherein the first chimney side panel, the second chimney side panel, the first collapsible chimney end wall, and the second collapsible chimney end wall can be raised to be substantially upright to form a chimney so as to expand the volume of the carton.

Abstract: A carton with a configurable dispenser that can be opened while resting on its side or on its bottom wall and that can dispense articles one at a time, in groups, or in a wholesale fashion. A restricted opening is formed by at least partial detachment of a dispensing flap, which permits limited access and side dispensing. An access opening is formed by at least partially detaching an unloading flap, which enhances the degree to which articles can be accessed and is useful for top unloading. The dispensing flap and the unloading flap are defined by two pairs of severance lines that diverge from a hand hold, dust flap or other tear initiation means and toward the side walls. The tear initiation means is off center, being positioned closer to one of the side walls of the carton than the other. Retention flaps cooperate with the remaining one of the dispensing flap and the unloading flap to restrain articles, particularly when the articles are dispensed while the carton rests on its side.

Abstract: A carton is provided with side walls that are shaped to securely or tightly enclose a group of tapered cylindrical articles. The curvature of the edges of each side wall is selected to cause the end wall or end closure structure to conform to the tapered shape of articles in the endmost row that is disposed adjacent to the respective end closure structure of the carton. More specifically, the edges of each side wall are substantially continuously arcuate and the curvature of the edge is determined such that the maximum width of each side wall is greater than the width of the respective bottom edge of the side wall.

Abstract: A carton for enclosing cylindrical articles includes a dispenser that provides access to at least two endmost articles in an uppermost row, and to at least one article in a lowermost row, when fully loaded. The dispenser is defined by contiguous severance lines that extend across the top wall, side walls, and end wall. The dispenser is opened by tearing the severance lines to define a stopper wall and as a recess in each side wall that, at its lowest point, is spaced at a distance above the bottom wall less than half the height of the carton, with the dimensions and position of the recess being sufficient to expose at least part of the ends of one or more lowermost articles. Each side wall severance line meets the end wall severance line at a distance above the bottom wall no less than half the height of the carton.

Abstract: A carton for enclosing and dispensing articles that can be configured to serve as a cooler for articles enclosed within the carton, such as beverage cans. The carton includes retention panels that are formed from a top wall of the carton and a pair of top end flaps that are detachable from end walls of the carton. The retention panels can be rotated to be coplanar with a respective side wall and the top end flaps can be elevated with respect to the end walls such that the retention panels and the top end flaps form a retaining structure.

Abstract: A carton for containing a plurality of articles such as cans includes a pair of side walls, a bottom wall, a top wall and end closure panels for at least partially closing the ends of the carton. The top wall is of multi-ply construction and the carton further comprises an opening provider defined by a series of weakened lines in the top, side and end walls. The opening provider includes at least one weakened line coincident at least in part with a stress relieving fold line to facilitate easy opening of the carton.

Abstract: A carrier (800) that is reversibly erectable from a collapsed condition to an erected condition and that reliably maintains its erected condition. The carrier includes a tubular portion defined by side walls (118, 146, 152, 142, 156, 160) and a bottom wall defined by bottom panels (230, 260). The bottom panels are hingedly connected to an edge of the tubular structure. Gusset structures connect the bottom panels to the tubular structure and cause the bottom panels to toggle as the carrier is erected. The gusset structures additionally retain the bottom wall in the erected condition. In the erected condition, the bottom wall of the carrier includes a buffer for limiting or preventing damage to articles as they are loaded into the carrier. The handle of the carrier is ergonomically defined in multiple planes and includes handle flaps including curved portions that improve the comfort of a handle.

Abstract: A reinforced handle is provided in an end wall closure of a sleeve type carton by forming a handle aperture in a top end flap, and by aligning the handle aperture with corresponding cutouts formed in respective side end flaps, each cutout being reinforced with one or more reinforcing panels that align with at least its weight bearing edge. Each reinforcing panel is hingedly attached to the respective side end flap to be foldable along the hinged connection and secured in a face contacting arrangement, whereby the reinforcing panel overlies the cutout as an overlay panel, or aligns its edge with the weight bearing edge of the cutout. In this manner, the material at the weight bearing edge of the cutout is at least two plies thick. When the carton is fully erected and sealed, the reinforced cutout is in registry with the handle aperture, thereby creating the reinforced handle.

Abstract: A carton (200) including a top wall (214), a bottom wall (218), opposing side walls (212, 216), and first and second end walls (220, 222). A detachable portion (210) of the carton (200) is defined by a severance line (180) to include at least a portion of the top wall (214) and a portion of the side walls (212, 216). The top wall portion (182) of the severance line (180) is spaced apart from the second end wall (222) by a certain distance D1 such that a portion of the top wall (214) remains to provide structural integrity to the carton (200) after the detachable portion (210) is detached. The distance (D1) is also determined such that articles (B) in the carton (200) are viewable and easily accessed. The minimum distance (D1) between a top wall portion (182) of the severance line (180) and the second end wall (222) is no greater than half of the distance between the first and second end walls (220, 222).

Abstract: A carton for dispensing articles having a dispensing feature is adapted for restraining articles within the carton until the consumer desires to remove the endmost articles from the carton. To erect the carton, a plurality of panels are connected together to define an end of the carton. A first detachable portion at the end of the carton may be detached from the carton to define an opening for dispensing articles from an upper or lower row of articles within the carton. A second detachable portion at the end of the carton borders the first detachable portion and may also be detached from the carton to enlarge the opening in an alternative embodiment. The second detachable portion restrains articles in an upper row of articles prior to detaching the second detachable portion from the erected carton.
