In one embodiment, the second top panel 29 includes a second handle portion in the form of reinforcement tape 111 extending across the central portion 83 of the second top panel and into the first top end flap 85 and the second top end flap 87. The reinforcement tape 111 can be adhesively applied to the exterior surface of the second top panel 29 and the top end flaps 85, 87. Alternatively, the reinforcement tape 111 could be applied to the interior surface of the first top panel 23 and or top end flaps 75, 77 without departing from the disclosure. Alternatively, the reinforcement tape 111 can be replaced by adhesive such as glue or other reinforcing material. Further, the reinforcement tape 111 could be omitted without departing from this disclosure.
The second top panel 29 further includes a third handle portion 113 and a fourth handle portion 115. The third handle portion 113 is formed by two spaced apart tear lines 117, 119 that extend from the central portion 83 of the second top panel 29 into the first top end flap 85. In one embodiment, a plurality of lateral fold lines 121 extend across the width of the third handle portion 113 extending between the tear lines 117, 119. The fourth handle portion 115 is similarly shaped as the third handle portion 113 and is at least partially defined by two spaced apart tear lines 123, 125 extending from the central portion 83 of the second top panel 29 into the second top end flap 87. A plurality of lateral fold lines 127 extend across the width of the fourth handle portion 115 extending between the tear lines 123, 125.
In one embodiment the tear lines 117, 119, 123, 125 have generally curved end portions in respective top end flaps 85, 87. As shown in
An exemplary method of erecting the carton 5 from the blank 3 is discussed in detail below and shown in
In one embodiment, the first end 67 has a rounded top corner 145 and a orthogonal bottom corner 147. Similarly, the second end 69 has a rounded top corner 149 and a orthogonal bottom corner 151. The first end 67 can be closed by folding the overlapped first top end flaps 75, 85 to be in contact with, or closely adjacent to, the respective curved edges 79, 89 of the first and second side panels 13, 15 to form the rounded top corner 145. Further, the overlapped first end flaps 75, 85 can be in contact with a respective container C that is located at the rounded top corner 145 of the carton 5. Alternatively, the overlapped first end flaps 75, 85, can be closely adjacent to the container C at the corner 145. As shown in
In one embodiment shown in
The handle 7 could have other features and could otherwise be shaped, arranged, configured, and/or activated without departing from the disclosure.
Any of the features of the various embodiments of the disclosure can be combined with, replaced by, or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure. Further, it is noted that the handle features and stress-relief areas of the various embodiments can be incorporated into a carton having any carton style or panel configuration. The carton styles and panel configurations described above are included by way of example.
The blanks according to the present invention can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blanks 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 blanks may then be coated with a varnish to protect any information printed on the blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks.
In accordance with the exemplary embodiments, the blanks may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blanks can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton package to function at least generally as described above. The blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
The above embodiments may be described as having one or more panels adhered together by glue. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels or flaps in place.
In accordance with the above-described embodiments of the present disclosure, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding there along. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines include: 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; and various combinations of these features.
As an example, a tear line can include: a slit that extends partially into the material along the desired line of weakness, and/or a series of spaced apart slits that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features. As a more specific example, one type tear line is in the form of a series of spaced apart slits that extend completely through the material, with adjacent slits being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent slits for typically temporarily connecting the material across the tear line. The nicks are broken during tearing along the tear line. The nicks typically are a relatively small percentage of the tear line, and alternatively the nicks can be omitted from or torn in a tear line such that the tear line is a continuous cut line. That is, it is within the scope of the present disclosure for each of the tear lines to be a continuous slit penetrating a portion of the thickness of the material or penetrating the entire thickness of the material, or the like. For example, a cut line can be a continuous slit or could be wider than a slit without departing from the present disclosure.
The foregoing description of the disclosure illustrates and describes various exemplary embodiments. Various additions, modifications, changes, etc., could be made to the exemplary embodiments without departing from the spirit and scope of the disclosure. It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Additionally, the disclosure shows and describes only selected embodiments of the disclosure, but the disclosure is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the disclosure.
This application claims the benefit of U.S. Provisional Application No. 61/633,709, filed Feb. 16, 2012, which is incorporated herein by reference in its entirety.
