[0011] Corresponding parts are indicated by corresponding reference characters throughout the drawings.

[0012] The present disclosure generally relates to various aspects of containers, structures, trays, materials, packages, elements, and articles, as well as methods of making such containers, structures, trays, materials, packages, elements, and articles. Although several different aspects, implementations, and embodiments are disclosed, many interrelationships between, combinations, and variations of the various aspects, implementations, and embodiments are contemplated hereby. In one illustrated embodiment, the disclosure relates to a container for holding, heating, cooking, and / or shielding food, beverages, or various other articles. However, in other embodiments, the container may be used to form articles that contain other than food, or may be used for refrigeration or other uses. As used herein, the terms "inside," "internal," "outside," "exterior," "lower," "bottom," "upper," and "top" refer to orientations determined with respect to a fully upright and erect carton.

[0013] FIG. 1A is a plan view of an inner surface 101 of a sidewall blank, generally designated 103, and FIG. 2A is a plan view of an inner surface 105 of a bottom blank, generally designated 107, which sidewall blank 103 and bottom blank 107 are used in cooperation to form a container 109 (FIG. 3) according to an exemplary embodiment of the present disclosure. In the illustrated embodiment, the container 109 is a cup for holding beverages and / or other liquids. Alternatively, the container 109 may be any suitable container, such as a cup, tray, bowl, etc., for holding food and / or beverage items or other suitable liquid and / or solid materials. The container 109 may be alternatively shaped and / or formed without departing from the scope of the present disclosure.

[0014] In the illustrated embodiment, the sidewall blank 103 has a longitudinal axis L1 and a transverse axis L2. In the illustrated embodiment, the sidewall blank 103 includes a top edge 113, a bottom edge 115, and first and second edges 117 and 119 extending from the ends of the top edge 113 and the bottom edge 115, respectively. In one embodiment, the top edge 113 can include a convex curve (e.g., having a radius of curvature extending away from the bottom edge 115) and the bottom edge 115 can include a concave curve (e.g., having a radius of curvature extending toward the top edge 113) such that the sidewall blank 103 forms a generally cylindrical sidewall that is at least partially tapered (e.g., the diameter of the top of the sidewall is greater than the diameter of the bottom of the sidewall), as shown by way of example in FIG. 3. Additionally, the edges 117, 119 can be inclined and extend at an acute angle relative to the transverse axis L2, as shown in FIG. 1. 2A, the bottom blank 107 can have a generally circular perimeter. The sidewall blank 103 and / or the bottom blank 107 can be otherwise shaped, positioned, positioned, and / or configured without departing from this disclosure. For example, one or more of the edges 113, 115, 117, 119 can be orthogonal or nearly orthogonal and / or straight or nearly straight, forming, for example, a cylindrical sidewall that is not tapered (e.g., has a generally constant diameter), without departing from this disclosure.

[0015] As shown in the schematic cross-sectional view of FIG. 1B, the sidewall blank 103 can include a sidewall substrate or support layer 121 extending along an outer surface 123 of the sidewall blank 103 and a primary layer or sidewall base coat 125 extending along an inner surface 101 of the sidewall blank 103. Similarly, as shown in the schematic cross-sectional view of FIG. 2B, the bottom blank 107 can include a bottom substrate or support layer 127 extending along an outer surface (or bottom surface) 129 of the bottom blank 107 and a bottom base layer or coat 131 extending along an inner surface 105 of the bottom blank 107. In one embodiment, each of the substrates 121, 127 can be formed from one or more layers of a paper-based material (e.g., paperboard, cardboard, etc.) and / or can be formed from any other suitable material. In an exemplary embodiment, the paperboard or other substrate material can be free of a clay coat or the like. In one exemplary embodiment, the base coat 125, 131 can be a liquid barrier layer that can help reduce fluids from being absorbed into and / or passing through the substrate, at least so long as the container 109 is intended to hold liquids.

[0016] In some embodiments, the base coat 125, 131 can be polyethylene (PE) or a similar material. PE and similar materials can be inexpensive, can be easily applied to the substrate 121, 127 (e.g., by extrusion or flood coating), and can provide sufficient heat seal properties to form the seams of the container 109, as described in more detail below. However, in embodiments, PE can be made from non-renewable sources and / or can pose difficulties in recycling containers formed from paper-based materials coated with PE (e.g., it can be difficult to sufficiently separate the PE and paper-based materials to recover the paper fibers and / or PE material for recycling). In some embodiments, materials can be used for the coating that can be made at least in part from renewable sources and / or can be more easily recycled (e.g., can be more easily separated from the paper-based substrate), and / or are compostable (e.g., in a residential environment and / or in a commercial composting process). Such materials can include water-based materials and / or other suitable materials. However, because these materials may be more expensive, coating the substrates 121, 127 with enough material to form a base coat 125, 131 that can provide a sufficient liquid barrier for the container 109 and allow heat sealing of the seams of the container 109 may undesirably increase the cost of the packaging. Reducing the thickness of the base coat 125, 131 may reduce the amount of the more expensive material used, but may result in a reduced heat sealability of the material (e.g., the thickness of the base coat may not have enough thermal mass to form a heat seal).

[0017] In the illustrated embodiment, the sidewall blank 103 may include a heat seal reinforcement layer or secondary layer 133 extending along the end margins 135 and bottom margin 137 of the sidewall blank 103. In an exemplary embodiment, the secondary layer 133 may be the same material as the base coat 125 or may be another suitable material. For example, the base coat 125 and secondary layer 133 may include any suitable material (e.g., any material suitable for coating a substrate and / or forming a heat seal), such as bio-based materials including ethylene vinyl acetate (EVA), polylactic acid (PLA) and polyhydroxyalkanoates (PHAs), other polyesters, PE, etc., in any suitable combination. The materials may be applied in an aqueous emulsion, which may be annealed to coalesce the polymers in the emulsion to form the respective layers. Alternatively, one or more of the layers may be applied by extrusion or other suitable methods.

[0018] 1A , the end margin 135 extends along the edge 117 of the sidewall blank 103, and the bottom margin 137 extends along the bottom edge 115 of the sidewall blank 103. In the illustrated embodiment, a second end margin 139 opposite the first end margin 135, which extends along the edge 119 of the sidewall blank 103, and a top margin 141 may be at least partially free of the secondary layer 133 (e.g., except where the end margin 139 intersects with the bottom margin 137 and where the top margin 141 intersects with the first end margin 135). Alternatively, in an exemplary embodiment, the secondary layer 133 may extend at the second end margin 139 and / or the top margin 141. In embodiments, the width of the secondary layer 133 (e.g., the distance the secondary layer 133 extends from the edge of the sidewall blank 103) is equal (e.g., about equal, roughly equal, substantially equal, etc.) to the amount of overlap at the sidewall seam and the bottom seam (e.g., as shown in Figures 4A-4C, described in more detail below). For example, the container can have an overlap of about 5 mm to about 10 mm, or other suitable amount of overlap. In embodiments, configuring the secondary layer 133 to fit within or match the seam width can help avoid material waste and control the cost of the container 109 and / or reduce the environmental impact of manufacturing the container. In some embodiments, the secondary layer 133 can cover, for example, less than or about 10% of the surface of the sidewall blank 103. In one exemplary embodiment, the secondary layer 133 can cover, for example, about 5% or less of the surface of the sidewall blank 103.

[0019] In the illustrated embodiment, the secondary layer 133 can have a thickness that, in addition to the thickness of the base coat 125 along the end margins 135 and bottom margin 137, respectively, provides sufficient material to form a sealed seam and attach the bottom blank 107 to the sidewall blank 103, as described in more detail below. In one embodiment, the secondary layer 133 can double the thickness of the heat seal material on the substrate 121. In an embodiment, the thickness of the layers (e.g., secondary layer 133 and / or base coat 125, 131) can be derived from the amount (e.g., weight) of aqueous emulsion applied to the web in forming the blank. For example, the secondary layer 133 can be applied with an aqueous emulsion having about 50% solids, at about 0.1 pounds to about 3 pounds of emulsion per 1000 square feet of substrate 121. Such application can have a thickness of about 2 microns to about 50 microns before annealing, and can result in the secondary layer 133 having a thickness of, for example, about 2 microns to about 25 microns after drying. Any of the base coats 125, 131 and / or secondary layer 133 may be omitted or may be otherwise shaped, arranged, positioned, and / or configured without departing from this disclosure. For example, secondary layer 133 may extend over second end margin 139 in addition to or instead of first end margin 135.

[0020] In the illustrated embodiment, the sidewall blank 103 and bottom blank 107 can be formed into a container 109 having an interior 142 as shown in FIG. 3. For example, the sidewall blank 103 can be bent and curved (e.g., around a mandrel (not shown)) to form the sidewall 143 of the container 109. As shown in FIG. 3, the end margins 135, 139 adjacent the respective edges 117, 119 overlap one another to form a seam 145 of the sidewall 143. As shown in the schematic cross-sectional views of FIGS. 4A and 4B, the seam 145 includes portions of the base coat 125 and secondary layer 133 extending along the first end margin 135 that are positioned between portions of the substrate 121 extending along the first end margin 135 and the second end margin 139. The portion of the base coat 125 extending along the second end margin 139 faces the interior 142 of the container 109. In one embodiment, the base coat 125 and secondary layer 133 can cooperate to form a heat seal along the seam 145, and heat and / or pressure can be applied along the seam such that the base coat 125 and secondary layer 133 fuse together the edge margins 135, 139 to form a seal (e.g., a liquid-proof or liquid-resistant seal). The sidewall 143 and / or seam 145 can be formed differently without departing from this disclosure.

[0021] 3 and 4C, the bottom blank 107 can be secured to the inner surface 101 of the side wall 143 to form the bottom wall 147 of the container 109. In the illustrated embodiment, the bottom wall 147 and the side wall 143 can extend around and form the interior 142 of the container 109. In one embodiment, a margin portion 149 of the bottom wall 147 can be folded over a central portion of the bottom wall and attached in face-to-face contact with the bottom margin 137 of the side wall 143 to form a bottom seam 151 (FIG. 4C). Margin portion 149 of bottom wall 147 and bottom margin 137 of side wall 143 can be heat sealed together by application of heat and / or pressure such that secondary layer 133 of bottom margin 137 cooperates with base coat 125 of bottom margin 137 and / or base coat 131 of margin portion 149 to fuse margin portion 149 and bottom margin 137 together and form a seal (e.g., a liquid-proof or liquid-resistant seal) along bottom seam 151. Bottom wall 147 can be otherwise shaped and / or sealed to side wall 143 without departing from this disclosure.

[0022] In an exemplary embodiment, the sidewall blanks 103 can be arranged and formed on a web of material 153, as shown in Figures 5A and 5B. In one embodiment, the web of material 153 can be a substrate material. The base coat 125 can be applied (e.g., by flood coating, extrusion, printing, etc.) to the web of material 153 at a predetermined weight and / or thickness (e.g., a thickness sufficient to form a desired liquid-resistant layer). The coated web can be annealed, dried, and / or cooled, and a secondary layer 133 of each sidewall blank 103 can be applied to the coated web in registration along what will become the first end margin 135 and bottom margin 137 of the sidewall blank 103 in the web (Figure 5A). For example, the secondary layer 133 can be printed onto the coated web by a printing plate or roller (e.g., gravure printing), etc. After the web with the secondary layer 133 is annealed, dried, and / or cooled, the web can be cut along the edges of each sidewall blank 103 to form tear lines 155 that extend along the perimeter of the sidewall blank 103 (FIG. 5B). The sidewall blanks 103 can be removed from the web by separating the blanks from the web along the respective tear lines 155. The sidewall blanks 103 can be formed otherwise without departing from this disclosure.

[0023] In another embodiment, as shown in Figures 6A and 6B, the base coat 125 of each sidewall blank 103 can be printed on a web of material 153 in registration with the respective sidewall blank (Figure 6A). The coated web can be annealed, dried, and / or cooled, and the secondary layer 133 can be printed in registration at a second printing station. The web can then be dried and / or cooled, and the sidewall blanks 103 can be cut from the web. The sidewall blanks 103 can be formed differently without departing from this disclosure.

[0024] 7A and 7B, secondary layer 133' may be formed along margin portion 149' of bottom blank 125'. In an embodiment, secondary layer 133' may replace or supplement secondary layer 133 that extends into bottom margin 137 of sidewall 143 when bottom seam 151 is formed. Bottom blank 125' may be otherwise shaped, positioned, positioned, and / or configured without departing from this disclosure.

[0025] Any dimensions and / or other parameters set forth above or otherwise included in this disclosure are approximate and may be greater or less than those stated, or within or outside the recited ranges, without departing from the scope of the present disclosure. All dimensional information presented herein is intended to be illustrative of certain aspects of the present disclosure and is not intended to limit the scope of the present disclosure, as various other embodiments of the present disclosure may include dimensions greater than or less than those included herein.

[0026] Blanks according to the present invention can be formed, for example, from coated paperboard and similar materials. For example, the blanks can be coated on the inside and / or outside with a clay coat. Product, advertising, price codes, and other information or images can then be printed on the clay coat. The blanks can then be coated with a varnish to protect any information printed on the blank. One or both sides of the blanks can also be coated with, for example, a moisture barrier.

[0027] According to an exemplary embodiment, the blanks and / or other structures may be made of paperboard of a caliper such that it is heavier and stiffer than regular paper. The blanks may also be made of other materials such as cardboard, stiffened paper, or any other material having suitable properties to enable the carton package to function at least generally as described above.
