Referring to
As shown, the inner layer 103 has a waveform shape with the surface features 21 including a plurality of protrusions 105 spaced apart by respective channels 107 disposed and/or defined between and/or separating adjacent protrusions 105. As shown, each respective channel 107 can include substantially the entire region of the inner layer 103 between each respective adjacent protrusion 105 such that respective channels 107 parallel with respective protrusions 105. The protrusions 105 and channels 107 can have the same or similar lengths, or can have differing lengths without departing from the disclosure.
In this regard, the protrusions 105 and the channels 107 can form an alternating pattern such as that in a wave pattern, for example, a sinusoidal wave pattern. In this regard, the protrusions 105 and the channels 107 can form a pattern of the material 100 that can broadly be referred to as a single-face corrugated material or ribbed material. As shown, the channels 107 can extend longitudinally, or can have a different orientation, such as a laterally-extending or obliquely-extending orientation. In one embodiment, one or more of the protrusions 105 and/or the channels 107 can have a different cross-sectional configuration, for example, a configuration that is at least partially square, rectangular, triangular, or ovoid in cross-section. The protrusions 105 and/or the channels 107 could have other shapes without departing from the disclosure.
As shown, the protrusions 105 can have a hollow cross-sectional configuration, for example, such that a chamber 108 is defined between each protrusion 105 and the outer layer 101. In an alternative embodiment, the inner layer 103 can be configured such that the protrusions 105 have a substantially solid cross-sectional configuration such that no chamber is defined between the protrusions 105 and the outer layer 101. In the illustrated embodiment, each protrusion 105, as shown, has a curved configuration that presents an upper-facing or food-contacting surface 109 for supporting one or more food products F (
Each channel 107, as shown, has a curved configuration that can support, for example, portions of food products F, at a vertical position spaced above and away from the outer layer 101. In this regard, each channel 107 has a curvature that extends away from the outer layer 101, e.g., such that each channel 107 has a concave configuration relative to the outer layer 101. While the channels 107 have been illustrated with the substantially similar configuration shown, one or more channels 107 can have a different configuration, for example, a cross-sectional configuration that is at least partially square, rectangular, triangular, or ovoid in cross-section, without departing from the disclosure. In this regard, the arrangement of the surface features 21 is such that a plurality of food-contacting surfaces 109 is provided spaced apart from one another, e.g., by respective channels 107.

In the assembled and open configuration of the container 15 illustrated herein, a food product F (
Referring additionally to the cross-sectional view of
In this regard, the surface features 21 provide a discontinuous surface along which the food product F is supported. In one embodiment, the food product F is a heated food product such that at least a portion of the heat H of the food product F can be transmitted to air in the channels 107. In this regard, the channels 107 and the overlying food product F create spaces of heated air below the food product F such that at least a portion of the heat H of the food product F is maintained in one or more of the channels 107 and is in convective contact with the food item F, for example, to contribute to maintaining a condition such as the temperature of the food item F. Additionally, heat H in the channels 107 is inhibited or prevented from escaping into upper portions of the interior 23 of the container 15 to minimize, inhibit, and/or prevent heat losses from the food item F. In one embodiment, the one or more channels 107 beneath the food product F provide a degree of thermal insulation for the food product F that maintains the temperature of the heated food product F. It will be understood that one or more of the chambers 108 below the protrusions 105 can additionally or alternatively maintain heat H to minimize, inhibit, and/or prevent heat losses from the food item F and/or provide a degree of thermal insulation for the food product F as described above with regard to the channels 107.
Furthermore, the channels 107 can support and/or capture a portion P of the food product F that may become separated from the food product F, for example, runoff from the food product F (e.g., oil or grease) or particulate from the food product F (e.g., crumbs) that falls into one or more of the channels 107, for example, due to shifting and/or under the influence of gravity. The channels 107 can also support moisture from the environment in the interior 23 of the container 15 (e.g., vapor or condensation from steam). In this regard, the channels 107 can provide pathways for runoff, or drainage from the food product F and/or the surrounding environment, for example, to maintain a desired condition, e.g., crispness, minimization of grease buildup, minimization of pooling or soaking of liquids, etc., of the food product F.
Accordingly, and as described herein, the surface features 21 provide thermally insulative properties for the food product F and the container 15 as well as being configured for capturing and/or draining runoff and/or particulate from the food product F and/or moisture from the surrounding environment. Such advantages are provided by the configuration of the surface features 21, which can provide ecological advantages and cost savings compared to, for example, conventional containers that lack such surface features. For example, because the inner layer 103 is devoid of a liner, linerboard, or other covering adjacent the surface features 21, cost and materials savings are realized with respect to such liner, linerboard, or other covering.

In general, the blanks described herein may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blanks can also be constructed of other materials, such as cardboard, sheet plastics or any other material having properties suitable for enabling the containers to function at least generally as described above. The blanks 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 container embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure portions of the container 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.
