Abstract

A carton for cans in two rows is provided wherein a base wall of the carton is formed from a pair of overlapping panels (12, 20) of the carton secured together so that the carton walls are tensioned around articles contained in the carton wherein the carton is adapted to be utilized such that a lower most row of cans (C) is in rolling contact with one (14) of the carton side walls (14, 18) disposed to act as the base of the carton and wherein article retaining means (74a, 51a, 51b) are provided at least partially to close one end of the carton to discourage dislodgement of the articles from that end of the carton and access means (30) is provided at the one end of the carton, the removal of which releases the upper row of cartons from restraint by the article retaining means but maintains the article retaining means effective for the lower row of articles, and wherein removal of the access means further relieves tension of the carton walls about the articles to facilitate their removal from that end of the carton.

Description

CARTON WITH DISPENSING FEATURE FOR CANS
Background of the Invention
This invention relates to a carton, preferably a wraparound carton, which is particularly, but not exclusively, a carton for cans and includes detachable means at one end of the carton the detachment of which removes article restraining means and facilitates access to the carton contents.
Cartons for encasing and dispensing multiple articles such as soft drink cans or bottles are useful for enabling users to transport, store, and access the articles for consumption. The user typically prefers the ability to easily retrieve one article from the carton at a time. To that end, it is desirable to have cartons with dispensers which allow one article to be removed at a time, while continuing to encase the remaining articles. The user tears out a detachable portion of the carton to form an access opening from which articles may be dispensed.
When the articles contained in the carton are cylindrical, and are disposed in the carton upon their sides, it is important that the articles be constrained such that the remaining articles do not unexpectedly and undesirably roll out of the dispenser when one is removed. Thus, it can be appreciated that it would be desirable to have a carton with a dispenser that constrains articles to prevent the articles from undesirably rolling from or otherwise exiting the carton when one article is removed.
As a carton may be stored in a restrictive space such as on a refrigerator shelf, it is advisable to provide an access opening that enables a user to access an end of an article to pull the article out of the carton end rather than having to lift the article out of the top of the carton. End removal of articles is especially advantageous where the carton is to be stored on an adjustable refrigerator shelf, because the user is able to optimize storage space by conforming the height of the shelf to the height of the carton, without obscuring the access opening.
It is known to provide a carton having an end accessible dispenser for articles, such as those shown in U.S. Patent Nos. 6,283,293 and 6,578,736. Advantageously, these cartons enable the user to access either the end or side of a cylindrical article through an access opening, such that the article can be removed from the carton through the end and/or top wall portion of the access opening without undesired exit of the other articles in the carton. However, the known end accessible dispensers have been available primarily for end-loading cartons and particularly for fully enclosed, end-loading cartons. There have not been many wraparound- style cartons that were provided with end accessible dispensers that were designed such that the articles in the carton may be removed one at a time through an open end while the other articles are well retained within the carton or otherwise the integrity of the carton was well maintained.
Therefore, there is a need for an improved article dispenser or a carton with such an article dispenser that is convenient to use with open-ended cartons and facilitates access to and removal of articles. Summary of the invention
One aspect of the invention provides a carton for cans in two rows wherein a base wall of the carton is formed from a pair of overlapping panels of the carton secured together so that the carton walls are tensioned around articles contained in the carton wherein the carton is adapted to be utilized such that a lower most row of cans is in rolling contact with one of the carton side walls disposed to act as the base of the carton and wherein article retaining means are provided at least partially to close one end of the carton to discourage dislodgement of the articles from that end of the carton and access or dispenser means is provided at said one end of the carton, the removal of which releases the upper row of cartons from restraint by said article retaining means but maintains said article retaining means effective for said lower row of articles, and wherein removal of the access or dispenser means further relieves tension of the carton walls about said articles to facilitate their removal from that end of the carton.

FIGS. 1-6 illustrate a first embodiment of the present invention, in which FIG. 1 shows a blank (10) from which the wraparound carton of FIGS. 3 and 4 is erected. The blank (10) is vertically elongate as viewed in FIG. 1 and is formed, in this embodiment, of paperboard. However the blank maybe formed of other foldable material such as corrugated board, plastic or the like. The blank (10) of this embodiment is designed for packaging ten articles of an identical configuration, such as beverage cans, arranged in two rows of five articles each. The blank (10) includes a rectangular top panel (16) located at the centre of the blank (10). The side panel (18) is connected to the top panel (16) along a fold line (26) and a further rectangular side panel (14) is connected to the side panel (16) along a fold line (24). A pair of base panels (12, 20) can form a composite bottom wall. Base panel (12) is connected to the side panel (14) by a fold line (22) and base panel (20) is connected to the side panel (18) by a fold line (28).
Along each of the edges of the side panel (18), top panel (16) and side panel (14) are fold lines (68a) and (68b) which connect the main panels of the blank (10) to a series of end panels and retention panels. The side panel (18) is foldably connected to end panels (82a) and (82b), the top panel (16) is foldably connected to retention panels (74a) and (74b) and similarly the side panel (14) is foldably connected to end panels (66a) and (66b). The retention panels (74a, 74b) are connected to the adjacent end panels (82a, 66a, 82b, 66b) by fold lines (78a, 73a) respectively.
Each of the overlapping base panels (12) and (20) are connected at each end to stopper flaps (51a, 51b, 51c, 51d). Overlapping base panel (12) is connected at each end to stopper flaps (51a) and (51d) by fold lines (58a). Similarly overlapping base panel (20) is connected at each end to stopper flaps (51b) and (51c) by fold lines (58a). Each of the stopper flaps (51a, 51b, 51c, 51d) are also foldably connected to the adjacent end panels (66a, 82a, 82b, 66b).
FIGS. 2A-2E show the sequential erecting of a stopper flap (5 Id). FIG.2A is a corner section of blank (10) showing the overlapping base panel (12) connected to the stopper flap (5 Id) which is connected to the adjacent end panel (66b). The end panel (66b) comprises two fold lines (72b, 64d) which are positioned diagonally with respect to the fold lines (68b, 58b) and (24, 22) and define two gusset sections (70b, 56d). In erecting the carton, the end panel (66b) is folded in flat face contacting relationship with the inside surface of side panel (14) as the top panel (16) and overlapping base panel (12) fold inward to create the wraparound carton as illustrated in FIG. 2B. The gusset sections (70b, 56d) fold in the opposite direction to the top panel (16), that being outwardly as illustrated in FIG. 2C. The stopper flap (5 Id) and retention panel (74b) are then urged to fold at angles to the overlapping base panel (12) and top panel (16) as illustrated in FIG. 2D. The stopper flap (5 Id) and retention panel (74b) then serve to partially close the end of the tubular carton as illustrated in FIG. 2E and further illustrated in FIG. 3., which shows a carton erected from the blank (10) with stopper flaps (51a, 51b) and retention panel (74a) partially closing the end of the tubular carton.
The overlapping base panels (12) and (20) are provided with a panel interlocking arrangement for securing the base panels (12) and (20) together in an overlapping relationship. The arrangement includes a pair of male and female tabs (L) that are struck from, and hingedly connected to the overlapping base panels (12) and (20). These tabs are well known in the art as means for holding an elongate blank in a tubular form that is tightly wrapped around a group of articles (C). FIG. 4 shows a perspective view of a carton erected from the blank (10) illustrating the overlapping base panels (12) and (20) together in an overlapping relationship, held by the male and female tabs (L).
In use the carton stands on its side wall 14 so that side wall 18 is then viewed as the top wall and the base panels are exposed on one side of the carton. Thus, the lowermost row of cans abut the side wall panel 14.
The side panel (18) comprises access or dispenser means, which in the preferred embodiment of the invention is a two-part removable portion. The first portion comprises a section (34) of the side panel (18) which is defined by a severance line (49) which outlines a pull tab (48), which is hingedly connected to section (34) by a fold line (50). Section (34) is further defined by tear lines (37) which may extend into the top panel (16) and base panel (20) along tear lines (35) and (39) as in the preferred embodiment of the present invention. The extended tear lines (35) and (39) define sections (32) and (36) respectively which are foldably connected to section (34) along fold lines (38) and (40). Collectively sections (34), (48), (32) and (36) form the first removable portion of the two-part removable portion, which also incorporates the stopper (51b) and a part of the retention tab (74a) defined by a further tear line (33). Removal of the first removable portion allows access to the articles (C) contained within the wraparound carton. However, retention of the articles (C) which abut and can roll along the side wall 14 when the cans of the lower row are removed is maintained by the remaining part of retention panel (74a) and stopper flap (51a). FIG. 5 shows a perspective view of a tubular carton constructed from the elongate blank (10) and illustrates the access gained to the articles (C) by the removal of the first removable portion, whilst the remaining part of retention panel (74a) and stopper (51a) continue to provide retention of the lowermost articles within the carton. Also illustrated in FIG. 5 is the removed, first removable portion.
The side panel (18) further comprises a second removable portion (42) struck from, and hingedly connected to the side panel (18) by fold line (46) which also hingedly connects pull tab (44) to the second removable portion (42). The second removable portion (42) is connected to the first removable portion by severance line (49) and together the two removable portions form the two-part removable portion.
Access panels are well known in the art for solely providing access to the articles contained within a carton. In the present invention the second removable portion (42) serves a dual purpose when removed; to provide access to the articles (C) and to relieve tension in the carton and thus release the rearmost articles held within the tubular carton. This is illustrated in FIG. 6 where upon removal of the second removable portion (42) it can be seen that the tension is relieved and the secured overlapping base panels (12, 20) may slacken slightly giving a greater degree of access to the articles (C).
FIGS. 7-9 illustrate a second embodiment of the present invention. Like reference numerals have been used for the like parts of the first embodiment and therefore only the differences from the first embodiment are described in any greater detail. FIG. 7 shows a blank (110) from which the wraparound carton of FIGS. 8 and 9 is erected. The blank (110) of FIG.7 different from the blank (10) of FIG.l in that the retention panels (74a, 74b) have been split to form, at the ends of top panel (116), pairs of stopper flaps (174a, 175a) and (174b, 175b), where each pair of stopper flaps (174a, 175a) and (174b, 175b) are separated by a free section at the ends of top panel (116). The free section between the pair of stopper flaps (174a,
175 a), which are on the same side of the blank (110) as the first removable portion, which comprises sections (148), (134), (132) and (136), may not be defined by a straight edge. In the second embodiment of the invention the free section between the pair of stopper flaps (174a, 175a) is defined by a rounded 'V shaped edge. The extended tear line (135) extends to the tip of the 'V shaped edge of the free section which may assist the easy removal of the first removable portion. In erecting the carton the stopper flaps (174a, 175 a) and (174b, 175b) are folded along fold lines (168a) and (168b) respectively and urged to fold at an angle to the top panel (16) to partially close the ends of the carton as shown in FIG. 8. A carton erected from the blank (110) of FIG.7 is shown in FIG.9 with the two-part removable portion removed.
Although the invention has been specifically described with reference to wraparound cartons, it will be appreciated that the invention is not limited to wraparound cartons.
