Those skilled in the art will appreciate the above stated advantages and other advantages and benefits of various additional embodiments reading the following detailed description of the embodiments with reference to the below-listed drawing figures.
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 disclosure.
Corresponding parts may be designated by corresponding reference numbers throughout the drawings.
Cartons or packages according to the present disclosure can accommodate articles of numerous different shapes. For the purpose of illustration and not for the purpose of limiting the scope of the disclosure, the following detailed description describes articles such as food products at least partially disposed within the carton embodiments. In this specification, the terms “lower,” “bottom,” “upper”, “top”, “front”, and “back” indicate orientations determined in relation to fully erected cartons.
As shown in
In the illustrated embodiment, a top flap 33 is foldably connected to the first side panel 21 at a tear line 35, a top flap 37 is foldably connected to the first side flap 23 at a tear line 39, and a top flap 41 is foldably connected to the second side flap 27 at a tear line 43. As shown, the tear lines 35, 39, 43 may have a curved configuration, e.g., convex as shown. As described herein, the top flaps 37 and 41 are joined to form a top flap 42 (
As shown, bottom flaps 45, 47, and 49 are foldably connected to the first side panel 21 at portions of a longitudinal fold line 51, a bottom flap 53 is foldably connected to the first side flap 23 at a portion of the fold line 51, and bottom flaps 55 and 57 are foldably connected to the second side flap 27 at portions of the fold line 51. The bottom flaps 47 and 57, as illustrated, may protrude further from the respective first side panel 21 and second side flap 27 than the bottom flaps 45, 49, 53, and 55. The bottom flaps 45, 53 and 49, 55 as shown, may be foldably connected to one another at portions of the respective fold lines 39, 43.
In this regard, the top flaps 37, 33, 41 extend along a first or top marginal area of the blank 3, and the bottom flaps 53, 45, 47, 49, 55, 51 extend along a second or bottom marginal area of the blank 3. It will be understood that the fold lines 35, 39, 43, 51, the flaps 45, 47, 49, 53, 55, 57, and/or other portions of the blank 3 may be otherwise shaped or configured without departing from the disclosure.
Still referring to
The side flap 23 also includes a fold line 77 having a curved configuration which intersects the fold line 25, the tear line 39, and the fold line 51, as shown in
As illustrated, the side flap 27 includes fold lines 79, 81, 84, and 83 that form sections 85, 87, 89, and 91 of the side flap 27, with section 89 being a central section and sections 85 and 24 being end sections. As described further herein, upon formation of the carton 5 (
In this regard, the sections 67, 69, 73, 75 and 85, 87, 92, 24 of the respective side panels 21, 31 are foldably reconfigurable via respective fold lines 59, 61, 64, 63, 65 and 79, 81, 84, 83, 77 such that portions of the side panels 21, 31 are reconfigurable between an outwardly protruding configuration or open position and an inwardly protruding or recessed configuration or closed position when the carton 5 (

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, the panels, flaps, and/or other features shown and described in conjunction with the blanks, the cartons, and/or the packages of the above embodiments are included by way of example. The inserts and/or other features of the disclosure can alternatively be associated with any suitable carton or blank having any panel and flap configuration.
The cartons according to the present disclosure can be, for example, formed from blanks of 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 blank. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described 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 to function at least generally as described herein. The blanks can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.
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 therealong. 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 replaced with a continuous slit, 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 above embodiments may be described as having one or more panels, flaps, or features, adhered together by glue during erection of the carton embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place.
The foregoing description of the disclosure illustrates and describes various embodiments. As various changes could be made in the above construction without departing from the 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. Furthermore, the scope of the present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments that are within the scope of the claims. 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 Patent Application No. 62/362,279, filed on Jul. 14, 2016. The disclosure of U.S. Provisional Patent Application No. 62/362,279, filed on Jul. 14, 2016, is hereby incorporated by reference for all purposes as if presented herein in its entirety.
