The present disclosure relates generally to various aspects of materials, blanks, packages, cartons, constructs, etc., for holding food items, and methods of making such materials, blanks, packages, cartons, and constructs. Although several different disclosures, aspects, implementations, and embodiments are provided, numerous interrelationships between, combinations thereof, and modifications of the various disclosures, aspects, implementations, and embodiments are contemplated hereby. In this specification, the terms “lower,” “bottom,” “upper,” “top,” “front,” and “back,” or other terms of orientation, indicate orientations determined in relation to fully erected cartons or packages and any such indication of orientations is not intended to limit the scope of the disclosure as the cartons or packages disclosed herein are capable of different orientations than shown and/or described herein.
As shown in
In one embodiment, the front panel 23 is foldably connected to a first end flap 45 and a second end flap 47. The bottom panel 25 is foldably connected to a third end flap 49 and a fourth end flap 51. The first back panel 31 is foldably connected to a fifth end flap 53 and a sixth end flap 55. The second back panel 32 is foldably connected to a seventh end flap 57 and an eighth end flap 59. The top panel 35 is foldably connected to a ninth end flap 63 and a tenth end flap 65.
As illustrated in
In the illustrated embodiment, the end flaps 45, 49, 53, 57, 63 extend along a first marginal area of the blank 13 and are foldably connected at a first longitudinal fold line 81 that extends along the length of the blank 13. The end flaps 47, 51, 55, 59, 65 extend along a second marginal area of the blank 13 and are foldably connected at a second longitudinal fold line 83 that also extends along the length of the blank 13. The longitudinal fold lines 81, 83 may be, for example, substantially straight, decoratively curved, or offset at one or more locations to account for the shape of the carton, for blank thickness, or for other factors.
In one embodiment, the first back panel 31 comprises cuts 85 and second back panel 32 comprises cuts 87. As shown in
In one embodiment, the end flaps 49, 51, 63, 65 each comprise a respective outer edge 93a, 93b, 93c, 93d. The edges, 93a, 93b can have a generally concave curved portion 95a, 95b and the edges 93c, 93d can have generally convex curved portion 95c, 95d. The lid panel 39 may comprise an outer edge 93f that is curved and may comprise two convex curved portions 97a, 97b and a concave curved portion 97c connecting the convex curved portions 97a, 97b.
In one embodiment, the front panel 23 comprises an outer edge 93g, and side edges 93h, 93i. In one embodiment, the outer edge 93g may be curved and may comprise two concave curved portions 99a, 99b and a convex curved portion 99c connecting the concave curved portions 99a, 99b. The front panel 23 can have a width “w” that matches the overall depth of the carton such that when the blank 13 is formed into a carton, at least a portion of the outer edge 93g is substantially approximate to or in contact with a portion of the top panel 35.
As shown in
In one embodiment, the male portions 101a, 101b are projections or tabs that extend outwardly from the side edges 115a, 115b of the front panel 23. The tabs 101a, 101b each respectively include a notch 117a, 117b adjacent the side edges 115a, 115b and a curved portion 119a, 119b (
As shown in
In one exemplary method of forming the blank 13 into the carton 15 having a base 133 and a reclosable lid 135, the blank 13 is first placed with the interior surface 137 facing up as illustrated in
As illustrated in
In one exemplary method of opening the carton 15, the front panel 23 is pushed inwardly generally at the center, releasing or disengaging the locking features 101a, 101b, 103a, 103b. The reclosable lid 135 is upwardly lifted and pivots at hinge or fold line 34 to the open position, as illustrated in
In another exemplary method of opening the carton 15, a force may be applied to the lid panel 39. If the lid 135 is attempted to be opened by applying a force near the center of the lid panel 39 (e.g., attempting to lift the lid 135 by grasping near the center of the lid panel 39), the sides of the lid 135 comprising end flaps 63, 65 flex inwardly resulting in outward movement of the locking tabs 101a, 101b through the openings 113a, 113b and displacement of the flaps 111a, 111b, causing more surface area of the locking tabs 101a, 101b to be engaged by the edges 139a, 139b, and causing an increase in the locking force that resists the opening of the lid. However, to open the reclosable lid 135 and prevent the locking force increase, the opening force may be applied to any area substantially off center, such as the edges 141a, 141b (
The carton 15 can be formed, closed, and/or opened by other alternative methods and steps without departing from the disclosure.
In general, the blank may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, sheet plastics or any other material having properties suitable for enabling the carton to function at least generally as described above. The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blanks may then be coated with a varnish to protect 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. The blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
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 of 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.
In accordance with the exemplary embodiments, 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 or depressed 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. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
The above embodiments may be described as having one or more panels adhered together by glue during erection of the carrier embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place, and is not intended to exclude heat, chemical, or frequency bonding techniques.
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. Additionally, the disclosure shows and describes only selected embodiments, but various other combinations, modifications, and environments are within the scope of the disclosure 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.
