The package of the present disclosure can be useful in containing one or more products (e.g., a food product) or other articles such as any suitable type of product that can be stored, transported, cooled, frozen, heated, and/or cooked (e.g., in a microwave oven). Some suitable products could comprise a frozen, refrigerated, or other pizza, sandwich, vegetables, popcorn, cuts of meat, or any other suitable food product or other article. Further, the package of the present disclosure can be used for heating, cooking, browning, crisping, etc. the food product by use of a heating or cooking device such as a microwave oven. It is understood that food products other than the food products listed herein may be contained in the package. Further, products contained in this package may be generally rectangular, triangular, round, square, irregular, or any other shape. In this specification, the terms “inner,” “interior,” “outer,” “exterior,” “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright packages.
FIG. 1 is a plan view of a blank, generally indicated at 101, used to form a package or tray (broadly “construct”) 103 (FIGS. 4-6) of an exemplary embodiment of the disclosure. In one embodiment, the blank 101 can have an interior surface 105 (FIG. 2) and an exterior surface 107 (FIG. 3). The tray 103 is used to hold and/or support a food product (not shown), such as a French bread pizza, sandwich, turnover, burrito, meats, or any other food product, during cooking, refrigerating, freezing, etc. of the food product. In one embodiment, at least a portion of the tray 103 may have an element (not shown) for use in cooking, heating, browning, and/or shielding (e.g., a microwave energy interactive element, such as, but not limited to, a susceptor) mounted thereto. Alternatively, a microwave energy interactive element can be omitted from the tray 103. In an alternative embodiment, the tray 103 can hold and/or support a non-food item or article.
The blank 101 has a longitudinal axis L1 and a lateral axis L2. The blank 101 includes a central panel 110 foldably connected to a first side panel 112 at a first longitudinal fold line 114. A second side panel 116 is foldably connected to the central panel 110 along a second longitudinal fold line 118. A first end panel 120 is foldably connected to the central panel 110 along a first lateral fold line 122 at one longitudinal end of the central panel 110, and a second end panel 124 is foldably connected to the central panel 110 along a second lateral fold line 126 at another longitudinal end of the central panel 110. As shown in FIG. 1, the central panel 110 can include a plurality stiffening features 128. Alternatively, the stiffening features 128 can be omitted or otherwise configured, arranged, or positioned without departing from the scope of the disclosure.
In the illustrated embodiment, the blank 101 includes end flaps 130, 132 foldably connected to the first end panel 120 along respective fold lines 134, 136 at respective ends of the first end panel 120. End flaps 138, 140 are respectively foldably connected to the second end panel 124 along the respective fold lines 142, 144 at respective ends of the second end panel 124. Each of the end flaps 130, 138, 132, 140 includes a locking feature, such as a projection 146 and a recess 148 for engaging a respective slit 150 in a respective side panel 112, 116. The end flaps could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure. For example, the locking features could be omitted from the end flaps 130, 132, 138, 140, and/or the end flaps 130, 138, 132, 140 could be glued to the respective side panels 112, 116. In an alternative embodiment, the end flaps 130, 138, 132, 140 could be foldably connected to the respective side panels 112, 116, and the slits 150 could be disposed in the end panels 120, 124. Alternatively, the end flaps 130, 132, 138, 140 could be omitted from the blank 101 without departing from the disclosure.
As shown in FIG. 1, the plurality of stiffening features 128 can include one or more patterns of bosses 152 formed in the central panel 110. Only a representative few of the bosses 152 are identified by their reference numbers in FIG. 1. In the illustrated embodiment, the bosses 152 can include emboss features 154 and deboss features 156 (FIGS. 2 and 3). For example, the emboss features 154 can comprise depressions or grooves in the interior surface 105 and raised portions in the exterior surface 107 of the blank 101, and the deboss features 156 can comprise raised portions in the interior surface 105 and depressions or grooves in the exterior surface 107. As shown in FIGS. 1-3, each of the bosses 152 is at least partially defined by an edge 158, which can be a transition between the bossed areas and the neutral area 160 of the central panel 110. For example, the neutral area 160 can be a generally planar portion of the central panel 110, and the bosses 152 can extend from the plane of the neutral area 160 at the edges 158. In one embodiment, the edges 158 can be generally perpendicular to the plane of the central panel 110. Alternatively, the edges 158 could be sloped or curved transitions. In one embodiment, one or more edges 158 could be a transition between an emboss feature 154 and a deboss feature 156. As shown in FIGS. 1-3, the bosses 152 are curved segments in circular (and/or other elliptical shapes), semicircular, or horseshoe-shaped (e.g., semielliptical) arrangements within the overall pattern of the plurality of stiffening features 128. The arrangements, patterns, and/or shapes of the bosses 152 are shown by way of example, and other arrangements, patterns, and/or shapes could be used. For example, in an alternative embodiment, the curved segments could be longer, shorter, enclosed shapes (e.g., circles, ovals, hourglasses, etc.), or any other suitable configuration.
As shown in FIGS. 2 and 3, the emboss features 154 and the deboss features 156 can alternate in the pattern of bosses 152 in the central panel 110. In alternative embodiments, the emboss features 154 and/or deboss features 156 could be otherwise configured. For example, the emboss features and/or deboss features could be grouped together, interspersed, or otherwise arranged. In another example, the bosses 152 could be all emboss features 154 or all deboss features 156. One or more of the bosses 152, emboss features 154, and/or deboss features 156 could be omitted or could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure.
In one embodiment, the blank 101 can be formed from a web of material. For example, areas of the material can be deformed upwardly with respect to the neutral area 160 to form the emboss features 154, and areas of the material can be deformed downwardly with respect to the neutral area 160 to form the deboss features 156. Any of the fold lines 114, 118, 122, 126, 134, 136, 142, 144, the cut lines 150, and/or the edges of the blank 101 could be formed before or after the bosses 152 in the web of material. The blank 101, including the bosses 152, could be otherwise formed without departing from the disclosure. Additionally, in alternative embodiments, the blank 101 could be otherwise shaped, arranged, and/or configured.
As shown in FIGS. 4-6 and described in the following in accordance with one acceptable example, the tray 103 is formed from the blank 101 by first upwardly folding the side panels 112, 116 along the respective longitudinal fold lines 114, 118 and folding the end panels 120, 124 along the respective lateral fold lines 122, 126. Each of the end flaps 130, 138 can be folded along the respective lateral fold lines 134, 142 into face-to-face contact with the exterior surface of the first side panel 112 and inserted into the respective slits 150 so that the projections 146 and recesses 148 engage the respective slits 150. Additionally, each of the end flaps 132, 140 can be folded along the respective lateral fold lines 136, 144 into face-to-face contact with the exterior surface of the second side panel 116 and inserted into the respective slits 150 so that the projections 146 and recesses 148 engage the respective slits 150. Accordingly, the first end panel 120 and the end flaps 130, 132 form a first closed end 164 of the tray 103. Similarly, the second end panel 124 and the end flaps 138, 140 form a second closed end 166 of the tray 103. Alternatively, the end flaps 130, 138, 132, 140 can be folded into face-to-face contact with the interior surfaces of the respective side panels 112, 116. As shown in FIGS. 4 and 5, the central panel 110, the side panels 112, 110, and the closed ends 164, 166 form the interior 170 of the tray 103. Alternative assembling, loading, and closing steps may be used without departing from the scope of the disclosure. For example, the end flaps 130, 138, 132, 140 can be glued into face-to-face contact with the respective side panels 112, 116 in addition, or alternatively, to interlocking the end flaps to the side panels via the projections 146 and the slits 150.
In the illustrated embodiment, the stiffening features 128 can help prevent buckling, bending, and/or other failure of the central panel 110. For example, the bosses 152 can be arranged so that little or none of the edges 158 are aligned with the grain of the blank 101 (in one embodiment, the grain is parallel to the longitudinal direction L1). For example, each of the edges 158 can have a length (e.g., extending around the perimeter of the respective boss 152), and the edge 158 can be nonparallel with the grain of the blank 101 along at least a majority of the length of the edge 158. In another embodiment, the edge 158 is nonparallel with the grain along at least a portion of the length of the edge 158. If the central panel 110 starts to buckle or fold, a fold or crease can start to propagate across the central panel. For example, in one embodiment, a central panel with the stiffening features omitted could form a fold (e.g., buckle) at one corner, and the fold could propagate to extend to the opposing corner, which could cause the tray to collapse. However, for the central panel 110, a fold or crease can intersect with a boss 152 and be redirected along the edge 158 of the boss. The fold can propagate along at least a portion of the edge 158, and the fold can stop or continue to another boss 152, which can further redirect the fold. Accordingly, the bosses 152 can disrupt a fold or crease in the central panel 110 and can help prevent a fold or crease from extending across the central panel 110 to help prevent failure of the tray 103. In one embodiment, the stiffening features 128 can result in a ten percent increase in strength of the central panel 110. For example, a central panel with the stiffening features and comprising an 18 point paperboard might replace a panel without the stiffening features and comprising 20 point paperboard.
In the illustrated embodiment, the plurality of stiffening 128 features is formed in the central panel 110 of the tray 103. In alternative embodiments, however, the stiffening features can be formed in one or more panels of any suitable construct (e.g., fully enclosed carton, wrap, basket carrier, divider panel, etc.). The blank 101 and tray 103 are included by way of example only. Additionally, as shown in FIG. 1, the bosses 152 comprise a certain percentage of the blank 101 (e.g., the total embossed and/or debossed area of the central panel 110 could be approximately 14% of the central panel). However, more or less of the blank could comprise embossed and/or debossed features (e.g., any suitable area of the central panel 110 could be embossed and/or debossed), and/or the bosses 152 could be longer, wider, shorter, narrower, or any suitable size without departing from the disclosure.
