1. Technical Field
The technical field relates to cartons for accommodating containers and packages formed therefrom.
2. Related Art
Cartons for engaging and securing upper portions of containers are known. The containers are typically inserted through apertures in a bottom panel of the carton and secured by engaging radially protruding parts of the containers. One such carton is disclosed in U.S. Pat. No. 6,223,892 to Bakx. Conventional cartons, however, may not securely retain the containers, or may fail to satisfy other requirements recognized in the art.
SUMMARYAccording to a first aspect of the invention, a package comprises a plurality of containers accommodated in a carton. The carton comprises a top panel, a bottom panel, a first side panel, a second side panel, a plurality of first struts extending from the bottom panel along a first row, a plurality of second struts extending from the bottom panel along a second row, a first row of first container apertures, each first container aperture being adjacent to one of the plurality of first struts, and a second row of second container apertures, each second container aperture being adjacent to one of the plurality of second struts. Each first strut comprises an upper first strut section, a lower first strut section foldably connected to the bottom panel, and a first inner brace aperture. Each second strut comprises an upper second strut section, a lower second strut section foldably connected to the bottom panel, and a second inner brace aperture. The inner brace apertures may include lower brace edges that support flanges of the containers accommodated in the carton.
According to a second aspect of the invention, the side panels of the carton can include outer brace apertures through which portions of the container flanges extend. The outer brace apertures have lower brace edges that support the undersides of the container flanges. During erection of the carton, the carton blank can be tightly wrapped around the upper portions of the containers to securely retain the containers within the carton.
According to the above aspects of the invention and additional aspects described below, the brace apertures and the struts serve to prevent the containers from inadvertently being pulled downward through the container apertures, and also prevent excessive movement or pivoting of the containers.
Other aspects, features, and details of the present invention can be more completely understood by reference to the following detailed description, taken in conjunction with the drawings and from the appended claims.
According to common practice, the various features of the drawings discussed below are not necessarily drawn to scale. Dimensions of various features and elements in the drawings may be expanded or reduced to more clearly illustrate the embodiments of the invention.
The present embodiments are addressed to cartons for attachment to containers. The cartons engage and secure upper portions of the containers to form a package.

The transverse fold lines 21, 31, 41, 51 in the blank 8 can be more generally referred to as “lines of weakness” or “lines of disruption” in the blank about which the blank is foldable. Each of the transverse fold lines 21, 31, 41, 51 may be interrupted at one or more locations, for example, and need not be continuous across the transverse direction of the blank 8. One or more cuts may be, for example, placed along one or more of the transverse fold lines 21, 31, 41, 51. In the exemplary embodiment illustrated in
The bottom panel 30 includes a plurality of first container-receiving patterns 80 and a plurality of second container-receiving patterns 100. The first container-receiving patterns 80 are arranged in a first row, and the second container-receiving patterns 100 are arranged in a second row spaced from the first row. Each container-receiving pattern 80, 100 is shaped and sized to receive an upper portion of a container 170 that is to be held within the erected carton 150. In the exemplary embodiment, two columns of first container-receiving patterns 80 and two columns of second container-receiving patterns 100 are formed in the bottom panel 30 so that four containers 170 can be accommodated in the erected carton 150, forming a 2×2 package. Other package configurations, such as 2×3, 2×4 or 2×5, 3×2, etc. are also within the scope of the present invention.
Each first container-receiving pattern 80 defines a first strut 81. Each second container-receiving pattern 100 defines a second strut 101. Each first strut 81 includes an upper first strut section 84 and a lower first strut section 86 foldably connected to the upper section 84 at a transverse fold line 82. The first lower strut sections 86 are foldably connected to the bottom panel 30 at transverse fold lines 88. Each second strut 101 includes an upper second strut section 104 and a lower second strut section 106 foldably connected to the upper section 104 at a transverse fold line 102. The second lower strut sections 106 are foldably connected to the bottom panel 30 at transverse fold lines 108.
The first struts 81 include first inner brace apertures 90 cut from the lower first strut sections 86. The second struts 101 include second inner brace apertures 110 cut from the lower second strut sections 106. The first inner brace apertures 90 include lower brace edges 92, and the second inner brace apertures 110 include lower brace edges 112. The inner brace apertures 90, 110 are sized to receive a part of a flange of a container 170 in the interior of the erected carton 150 (illustrated in
The first side panel 20 includes first outer brace apertures 22. The number of first outer brace apertures 22 may correspond to the number of columns of first container-receiving patterns 80 and to the number columns of patterns 100. Referring also to

The second top panel 50 is folded about the transverse fold line 51 so that it extends over the tops of the containers 170 disposed within the second row of container apertures 105. The upper strut sections 84, 104 now extend generally parallel to the bottom panel 30. The distal edge 105 of each upper first strut section 104 is complementary in shape with one of the adjacent recess 54 formed in the edge of the second top panel 50. The complementary shape of the edges 105 with the recesses 54 allows the upper second strut sections 104 and the second top panel 50 to lay adjacent to one another on the top of an adjacent flange 175 without the upper strut sections 104 overlapping the top panel 50. When the first top panel 10 is folded over the upper strut sections 104 and the second top panel 50 to close the top of the package, the resulting top panel will therefore have a smoother, flatter appearance.
The first top panel 10 is folded about the transverse fold line 21 so that the underside of the first top panel 10 can be adhered or otherwise secured to the upper surface of the second top panel 50, forming a top panel 120, as shown in
When closing the carton 150, the first top panel 10 and the second top panel 50 can be brought together and joined relatively tightly so that the flanges 175 of the containers 170 extend through and are supported in the outer brace apertures 22, 42 in the side panels 20, 40, respectively. At the exterior edge of the carton 150, the undersides of a flange 175 of a container 170 accommodated in a first container aperture 85 is thereby securely engaged with a first brace edge 24, and the underside of a flange of a container accommodated in a second container aperture 105 is securely engaged with a second brace edge 44.
In the interior of the carton, the first struts 81 support the containers 170 accommodated in the first row of container apertures 85, and the second struts 101 support the containers 170 accommodated in the second row of container apertures 105. Referring also to
According to the above embodiment, containers 170 are securely retained by the outer brace apertures 22, 42 in the side panels 20, 40 and by the struts 81, 101 in the carton interior. The containers 170 are thereby secured against being pulled downwardly through the bottom panel 30, and are also secured against excessive translation and/or pivoting within the carton 150.
The exemplary embodiment shown in
In this specification, the term “flange” indicates any radially projecting rim, collar, ring, raised portion or protrusion extending from an upper portion of a container.
The blank 8 according to the present invention can be, for example, formed from coated paperboard and similar materials. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the resultant package to function at least generally as described in this specification.
The interior and/or exterior sides of the blank 8 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 layer, on either or both sides of the blank, or laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
In accordance with the exemplary embodiment of the present invention, a fold line can be any substantially linear, although not necessarily straight, form of disruption or weakening in the blank 8 that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present invention, fold lines include: score lines; crease lines; a cut or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features.
The above embodiments may be described as having one or panels adhered together by glue. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place.
The description is not intended to limit the invention to the form disclosed herein. Also, it is intended that the appended claims be construed to include alternative embodiments, not explicitly defined in the detailed description.
