It is understood that food products other than the food products listed herein may be contained in the package. Further, food products contained in this package may be generally triangular, round, square, rectangular, irregular, amorphous, or any other shape. In this specification, the terms “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright packages.

FIG. 1 is a plan view of an interior side 101 of a tray blank, generally indicated at 103, used to form a tray 105, with an interior 107 (FIGS. 2 and 5), according to a first exemplary embodiment of the disclosure. The tray 105 can be used to hold a food product (not shown). In the illustrated embodiment, the tray 105 is generally rectangular-shaped and can be suitable for holding a food product of any shape (e.g., vegetables, fruit, sliced deli meats or cheeses, ground beef, chicken cutlets, etc.) in a suitable manner for purchase at a grocery store or other retailer, but the package could be otherwise shaped with the same or a different number of side panels to hold correspondingly shaped food products. Further, the tray 105 and blank 103 may be alternatively sized, shaped and/or otherwise arranged to hold any number of food products including a single food product or more than two food products. In one embodiment, the tray 105 is useful for holding the food product during storage in a refrigerator, a freezer, on display on shelves or in a deli case, during heating and/or cooking, and/or during serving or consumption of the food product.

As shown in FIG. 1, the tray blank 103 has a longitudinal axis L1 and a lateral axis L2. In the illustrated embodiment, the tray blank 103 comprises a bottom panel 110 foldably connected to a first side panel 112 at a lateral first fold line 114. A second side panel 116 is foldably connected to the bottom panel 110 at a lateral second fold line 118. A first end panel 120 is foldably connected to the bottom panel 110 at a longitudinal third fold line 122, and a second end panel 124 is foldably connected to the bottom panel 110 at a longitudinal fourth fold line 126. The blank 103 includes gusset panels 128, 130 respectively foldably connected to the first side panel 112 at fold lines 132, 134 located at respective ends of the first side panel. Gusset panels 136, 138 are respectively foldably connected to the second side panel 116 at fold lines 140, 142 located at respective ends of the second side panel. The gusset panels 128, 136 can be separable from respective ends of the first end panel 120 along tear lines or cuts 144, and the gusset panels 130, 138 can be separable from respective ends of the second end panel 124 along tear lines or cuts 146.

As shown in FIG. 1, a first reinforcing structure 147 (broadly, “first reinforcing structure features”) and a second reinforcing structure 159 (broadly, “second reinforcing structure features”) can be foldably connected to the respective first and second side panels 112, 116. The first reinforcing structure 147 can include a first reinforcement panel 148 foldably connected to the first side panel 112 along a lateral fold line 150 and a second reinforcement panel 152 foldably connected to the first reinforcement panel 148 along a lateral fold line 154. The second reinforcing structure 159 can include a first reinforcement panel 160 foldably connected to the second side panel 116 along a lateral fold line 162 and a second reinforcement panel 164 foldably connected to the first reinforcement panel 160 along a lateral fold line 166. In one embodiment, the fold lines 150, 162 are crease lines but the fold lines could be other lines of weakening (e.g., lines of weakening formed by partial or full cuts separated by nicks or portions of material between the cuts that are free from any form of weakening, cut/crease lines, etc.) without departing from the disclosure. Further, as shown in FIG. 1, the fold lines 154, 166 are lines of weakening formed by full cuts separated by nicks or portions of material between the cuts that are free from any form of weakening, but it is understood that the fold lines 154, 166 could be other lines of weakening without departing from the disclosure.

In the illustrated embodiment, each of the first and second end panels 120, 124 can include a respective end reinforcement flap 172, 174 respectively foldably connected to one of the first and second end panels at a respective longitudinal fold line 176, 178. The first and second end panels 120, 124 can include a lip or edge 173, 175 on either or both sides of the of the end panels adjacent the respective end reinforcement flaps 172, 174. In one embodiment, the edges 173, 175 extend obliquely from respective ends of the fold line 176, 178. The blank 103 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, the gusset panels could be foldably connected to the end panels 120, 124 instead of the side panels 112, 116, or the gusset panels could be omitted. Additionally, any of the panels and flaps of the blank 103 can be omitted without departing from the scope of this disclosure.

As shown in FIGS. 1-5, the blank 103 is formed into the tray 105 with an interior 107 by folding the first and second side panels 112, 116 and the first and second end panels 120, 124 relative to the bottom panel 110 along respective fold lines 114, 118, 122, 126. The gusset panels 128, 136 are folded along the respective fold lines 132, 140 and adhered in face-to-face contact with an interior surface of the first end panel 120 so that the gusset panels are attached to the end panel and form a portion of the interior 107 of the tray 105. The gusset panels 130, 138 are folded along the respective fold lines 134, 142 and adhered in face-to-face contact with an interior surface of the second end panel 124 so that the gusset panels are attached to the end panel and form a portion of the interior 107 of the tray 105. Accordingly, the erected gusset panels 128, 130, 136, 138 in face-to-face contact with the respective end panels 120, 124 form reinforced ends 182, 184 of the tray 105. The ends 182, 184 of the tray 105 can be alternatively, shaped, arranged, and/or configured without departing from the disclosure.

As shown in FIGS. 3-5, the first reinforcing structure 147 can be formed to reinforce the rim of the tray 105 by folding the second reinforcement panel 152 relative to the first reinforcement panel 148 at fold line 154, in the direction of arrow A1 (FIG. 3), and adhering the second reinforcement panel 154 in face-to-face contact with the first reinforcement panel 147 (FIGS. 3 and 4). From the position shown in FIG. 4, the first reinforcement panel 148 with the second reinforcement panel 152 attached thereto is downwardly folded in the direction of arrow A2 and adhered to the upper portion of the first side panel 112. The folding sequence of the reinforcing structure 147 provides three layers of material at the upper portion or rim of the first side panel 112, with the second reinforcement panel 152 attached to the upper portion of the first side panel and attached to the first reinforcement panel 148. In this way the second reinforcement panel 152 is in face-to-face contact with both the first side panel 112 and the first reinforcement panel 148 to reinforce the upper portion or rim of the first side panel. The second reinforcing structure 159 can be formed to reinforce the rim of the tray 105 in a similar manner as the first reinforcing structure 147 so that the second reinforcement panel 164 is in face-to-face contact between and attached to both of the second side panel 116 and the first reinforcement portion. When the reinforcing structures 147, 159 are formed, the fold lines 150, 162 form the upper edge of the tray 105 at the side panels 112, 116 with the reinforcing structures being foldably connected to the side panels at the fold lines 150, 162 and depending downwardly from the upper edges to reinforce the upper portion or rim of the tray. The reinforcing structures 147, 159 can be alternatively configured or formed without departing from the scope of this disclosure. For example, reinforcing structures 147, 159 could be formed on blank 103 before folding the side panels 112, 116, end panels 120, 124 and adhering gusset panels 128, 130, 136, 138.

As illustrated in FIG. 1, the second reinforcement panels 152, 164 have a longitudinal width less than the longitudinal width of the first reinforcement panels 148, 160 such that when the reinforcing rim structures 147, 159 are formed the first reinforcement panels 148, 160 are spaced apart from the respective side panels 112, 116. Accordingly, the reinforcing rim structures 147, 159 form respective hollow rims 180 (FIGS. 3 and 5) defined between the first reinforcement panel 148, 160 and the respective side panel 112, 116. Further the hollow rims 180 may be defined by the respective free edge 181 (FIG. 3) of the respective second reinforcement panel 152, 164 and the respective fold lines 150, 162. The hollow rims 180 could be alternatively configured or formed without departing from the scope of this disclosure.

As shown in FIGS. 2-5, the end reinforcement flaps 172, 174 can be downwardly folded along the respective fold lines 176, 178 and adhered in face-to-face contact with respective end panels 120, 124. As such, the reinforced ends 182, 184 of the tray 105 comprise the respective end panels 120, 124, the respective pairs of gusset panels 128, 136 and 130, 138 that are folded in face-to-face contact with the respective end panels 120, 124, and the respective reinforcement flaps 172, 174 that are downwardly folded to overlap the respective end panels 120, 124. The tray 105 can be formed by other flap or panel positioning steps, and the tray 105 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, reinforcement flaps 172, 174 could be folded and adhered on blank 103 prior to forming the tray 105.

In the illustrated embodiment, the side panels 112, 116 and the end panels 120, 124 of the assembled tray 105 are sloped so that multiple trays 105 can be stacked with one or more trays each nested in the tray below. The reinforcing rim structures 147, 159 reinforce the upper portions of the side panels 112, 116 of the tray 105 and the reinforcement flaps 172, 174 and gusset panels 128, 136, 130, 138 reinforce the ends 182, 184 of the tray 105. The blank 103 and/or tray 105 could have other reinforcing features without departing from the disclosure.

One or more products, such as raw or prepared food products (not shown), can be inserted into the interior 107 of the tray 105. In one exemplary embodiment, the tray and product(s) can be wrapped in plastic or other material, sealing the product(s) in the tray to keep the product(s) fresh, to prevent contamination of the product(s), and/or to help prevent leaking of fluids. Additionally, an insert, a coating, an absorption pad, or other features can be applied to the tray to help control fluids and/or retain the product(s) in the tray.

A blank according to the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank 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 blank may then be coated with a varnish to protect any information printed on the blank. The blank 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 blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the package to function at least generally as described herein. The blank 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 may 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 adhered together by glue during erection of the package embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure package panels in place.
