The plurality of end flaps can further comprise a first top end flap 169 (broadly, “first end flap”) foldably connected to an interior edge of the top panel 131 circumscribing an opening 171 at a longitudinal line of weakening/fold line 173 and a second top end flap 175 (broadly, “second end flap”) foldably connected to the top panel 131 at an opposite edge thereof at a longitudinal line of weakening/fold line 177. In this regard, the top panel 131 extends at least partially around the opening 171 and the top end flaps 169, 175 can be positioned extending into the opening 171.

Each top end flap 169, 175, as shown, can include a respective base portion 177, 179 foldably connected to the top panel 131 at the respective longitudinal fold lines 173, 177, and a respective distal portion or attachment portion 181, 183 foldably connected to the respective base portion 177, 179 at a respective oblique line of weakening/fold line 185, 187.

The blank 103 and tray 105 formed therefrom can also include locking features for at least partially maintaining an erected configuration of the tray 105. Such locking features can include one or more of locking tabs 189, 191 protruding from the respective front end flaps 149, 161 and corresponding to respective lines of weakening 193, 195 interrupting the respective fold lines 145, 157 adjacent the respective back end flaps 147, 159. In this regard, the lines of weakening 193, 195 extend along the front panel 123. As described further herein, the locking tabs 189, 191 are for being at least partially received through the lines of weakening 193, 195 when the tray 105 is formed from the blank 103.

As described herein, the engagement features of the blank 103 and the tray 105 formed therefrom can include the top panel 131. In some embodiments, the engagement features can include one or more of the flange support panels 135, 139.

As also described further herein, the reinforcement features of the blank 103 and the tray 105 can include one or more of the flange support panels 135, 139.

Referring to FIGS. 2 and 3, according to an exemplary embodiment of the disclosure, formation of the tray 105 from the blank 103 can be performed by inverting the blank 103 such that the exterior surface 101 is positioned on a supporting surface and such that an interior surface of the blank 103 can be positioned facing upwardly.

The end flaps 143, 155 can be folded at respective portions of the fold lines 145, 157 into at least partial face-to-face contact with respective portions of the bottom panel 121, the end flaps 149, 161 can be folded at respective portions of the fold line 145 into at least partial face-to-face contact with respective portions of the front panel 127, and the end flaps 147, 159 can be folded at respective portions of the fold lines 145, 157 into at least partial face-to-face contact with respective portions of the back panel 123. In the aforementioned arrangement, the end flaps 149, 161 can be positioned in at least partial overlapping relation.

Simultaneously or thereafter, the attachment portion 153 of the end flap 147 can be folded at the fold line 152 and positioned in at least partial face-to-face contact with a respective portion of the base portion 151 of the end flap 147, and the attachment portion 165 of the end flap 159 can be folded at the fold line 167 and positioned in at least partial face-to-face contact with a respective portion of the base portion 163 of the end flap 159.

The back panel 123 can be folded at the fold line 125 into at least partial face-to-face contact with the bottom panel 121, and the flange support panel 139 can be backfolded at the fold line 141 into at least partial face-to-face contact with a respective portion of the exterior surface of the back panel 123.

Simultaneously or thereafter, the top panel 131 can be folded at the fold line 137 into respective portions of the flange support panel 135 and the end flaps 149, 161. Such folding can position the end flaps 169, 175 into at least partial face-to-face contact with respective portions of the end flaps 149, 161.

The aforementioned arrangement of panels and end flaps can be at least partially maintained with one or more applications of adhesive such as glue G (FIG. 1). In particular, the interior surface of the respective attachment portions 153, 165 of the respective end flaps 147, 159 can be attached/adhered to the exterior surface of the respective end flaps 143, 155, the interior surface of the respective attachment portions 181, 183 of the respective end flaps 169, 175 can be attached/adhered to the exterior surface of the respective end flaps 149, 161, a longitudinally inner portion of the top panel 131 can be attached/adhered to the flange support panel 135, and a longitudinally outer portion of the top end panel 131 can be attached/adhered to the flange support panel 139.

Furthermore, such arrangement of the panels and flaps of the blank 103/tray 105 can be considered a collapsed configuration of the tray 105, e.g., for a space minimizing arrangement for shipping or storage.

As shown in FIGS. 2 and 3, the tray 105 can be reconfigured from the collapsed configuration to an erected configuration by positioning the front panel 127 and the back panel 123 in spaced and parallel arrangement, both panels 127, 123 generally upright relative to the bottom panel 121. The top panel 131 can also be in spaced and parallel arrangement with the bottom panel 121.

Simultaneously or thereafter, end flaps 149, 161 can be folded at respective portions of the fold lines 145, 157, e.g., away from the interior 107 of the tray 105. Such movement of the end flap 149 can cause the end flap 169 attached thereto to reconfigure such that the distal portion 181 thereof folds at the fold line 185 and into at least partial face-to-face contact with the base portion 177 thereof. This movement of the end flap 149 can also urge the end flap 143 (and, incidentally, the end flap 147 attached thereto) to fold at respective portions of the fold line 145 into a generally planar arrangement with the end flaps 149, 169. Such at least partially overlapping arrangement of the end flaps 143, 147, 149 can form a first closed end 109 of the tray 105.

Similarly, movement of the end flap 161 can cause the end flap 175 attached thereto to reconfigure such that the distal portion 183 thereof folds at the fold line 187 and into at least partial face-to-face contact with the base portion 179 thereof. This movement of the end flap 161 can also urge the end flap 155 (and, incidentally, the end flap 159 attached thereto) to fold at respective portions of the fold line 157 into a generally planar arrangement with the end flaps 161, 175. Such at least partially overlapping arrangement of the end flaps 155, 161, 163 can form a second closed end 111 of the tray 105.

Upon positioning the end flaps 149, 161 as described herein, the locking tabs 189, 191 protruding from the respective end flaps 149, 161 can be at least partially received through the respective lines of weakening 193, 195 in a locking arrangement, e.g., to maintain and/or enhance the erected configuration of the tray 105. In some embodiments, one or more portions of the respective locking tabs 189, 191 can engage one or more portions of the back panel 123 and/or respective end flaps 147, 159 adjacent the respective lines of weakening 193, 195.

The aforementioned arrangement provides the panels of the tray 105 extending at least partially around the interior 107 of the tray 105 and the plurality of end flaps overlapped to form a first closed end 109 and a second closed end 111 of the tray 105. Due to the relative attachment of longitudinally adjacent end flaps of the plurality of end flaps to one another, reconfiguration of the tray 105 from a collapsed configuration to an erected configuration can be accomplished efficiently and smoothly, for example, so as to minimize a required number of steps or associated machinery. For example, positioning the top panel 131 in generally spaced and parallel relation with respect to the bottom panel 121 can cause the aforementioned reconfiguration of end flaps to form the closed ends 109, 111 of the tray 105, e.g., so as to obviate the need to independently position the end flaps.

In this regard, the above-described arrangement of the blank 103 and tray 105 formed therefrom is such that the panels and flaps thereof are generally arranged extending in a single direction, e.g., along the longitudinal axis L1, to facilitate folding and gluing operations along a straight line to facilitate formation of the tray 105 on related forming machinery. For example, upon initial folding of the end flaps 143, 149, 151, 159, 155, 161, further folding operations are all along generally lateral lines of weakening spaced apart along the longitudinal axis L1.

It will be understood that one or more food products can be dropped, placed, or otherwise positioned in the interior 107 of the tray 105 during or subsequent to the aforementioned steps. In one embodiment, the food products can be tomatoes, though one or more of the food products can be a different food product without departing from the disclosure. The tray 105 can be provided with one or more food products as a package.

As described herein, engagement features of the tray 105 includes the top panel 131, which extends outwardly from the respective panels and closed ends 109, 111 to form a rim or flange 190 and one or more engagement surfaces for being engaged/supported by an element associated with a forming apparatus for the tray 105, for example a machine element such as a grasper, fork, pincer, rail, etc. In one embodiment, the exterior (e.g., downward facing) surface of the flange supporting panels 135, 139 can present engagement surfaces for being engaged/supported by such a machine component. In other embodiments, engagement surfaces can include any combination of one or more of the exterior, interior (e.g., upward facing), and/or side-facing surfaces of the top panel 131.

The positioning of the top panel 131 extending away from the panels of the tray 105, also presents a plurality of engagement/support surfaces for engaging/supporting a covering or lidding film, e.g., a plastic or other polymeric film, or other covering structure. In one embodiment, the lidding film can be provided as a polymeric layer that at least partially deforms in the presence of a heat source, e.g., a heat sealable film. The lidding film can thus be positioned extending across the opening 171 and in contact with one or more surfaces of the top panel 131 to cover the interior 107 of the tray 105 and maintain one or more conditions of the food products held therein, e.g., freshness, ripeness, moisture content, etc. It will be understood that the lidding film can minimize, inhibit, and/or prevent the passage of one or more materials into the interior 107 of the tray 105, for example, condensation or other moisture, insects or other pests, dirt, debris, etc. In one embodiment, the tray 105 can be provided together with the lidding film and one or more food products as a package.

Furthermore, the reinforcement features of the tray 105 can include at least the arrangement of one or both of the flange supporting panels 135, 139 in at least partial face-to-face contact with respective portions of the underside of the top panel 131/flange 190, the engagement of which can minimize, inhibit, prevent, and/or otherwise resist bending, bowing, flexing, buckling, curling, deflection, and/or other deformation of the flange 190. In this regard, forces exerted on the flange 190 via tension applied through a covering or lidding film disposed thereon can minimize, inhibit, and/or prevent deformation of the flange 190, e.g., to avoid undesirable product aesthetics, to avoid at least partial disengagement of the lidding film with the flange 190, to maintain a generally planar configuration of the flange 190 during use, storage, transport, etc. In some embodiments, the locking features of the tray 105 can additionally or alternatively be considered reinforcement features of the tray 105.

It will be understood that one or more of the panels, flaps, and associated features of the blank 103/tray 105 can have a different arrangement or configuration without departing from the disclosure. In one embodiment, one or more portions of the tray 105 can be separated at respective lines of weakening to facilitate access to the interior 107 of the tray 105.

Turning to FIG. 4, the exterior surface 201 of a blank 203 for forming a tray 205 according to a second exemplary embodiment of the disclosure is illustrated. The blank 203 and tray 205 formed therefrom can include one or more components that are the same or similar to those of the blank 103 and tray 105 of the first exemplary embodiment, and like or similar features are designated with like or similar reference numerals.

As shown, the blank 203 has the longitudinal axis L1, the lateral axis L2, the panels 121, 123, 127, 131, 135, 139 and associated features, and the end flaps 169, 175 and associated features. However, the blank 203 and the tray 205 formed therefrom can have a different configuration and arrangement of one or more end flaps foldably connected to a respective panel of the plurality of panels.

In the illustrated embodiment, a back end flap 243 can be foldably connected to the back panel 123 at a respective portion of the fold line 145, a bottom end flap 247 (broadly, “first end flap”) can be foldably connected to the bottom panel 121 at a respective portion of the fold line 145, and a front end flap 249 can be foldably connected to the front panel 127 at a respective portion of the fold line 149.

The bottom end flap 247, as shown, can include a base portion 251 foldably connected to the bottom panel 121 at the respective portion of the fold line 145, and a distal portion or attachment portion 253 foldably connected to the base portion 251 at an oblique line of weakening or fold line 252. As also shown, a locking tab 289 can be positioned extending from the attachment portion 253 of the end flap 247.

Similarly, a back end flap 255 can be foldably connected to the back panel 123 at a respective portion of the fold line 157, a bottom end flap 259 (broadly, “second end flap”) can be foldably connected to the bottom panel 121 at a respective portion of the fold line 157, and a front end flap 261 can be foldably connected to the front panel 127 at a respective portion of the fold line 157. The bottom end flap 259 can include a base portion 263 foldably connected to the bottom panel 121 at the respective portion of the fold line 157, and a distal portion or attachment portion 265 foldably connected to the base portion 263 at an oblique line of weakening or fold line 267, with a locking tab 291 positioned extending from the distal portion 263 of the end flap 259.

In addition, the line of weakening 193 can be positioned interrupting the fold line 145 adjacent the end flap 249 for at least partially receiving the locking tab 289 when the tray 205 is formed from the blank 203, and the line of weakening 195 can be positioned interrupting the fold line 157 adjacent the end flap 261 for at least partially receiving the locking tab 291 when the tray 205 is formed from the blank 203. In this regard, the lines of weakening 193, 195 can at least partially extend along the back panel 127.

Referring to FIGS. 5 and 6, according to one embodiment of the disclosure, formation of the tray 205 from the blank 203 can be performed in a manner similar to that described above with regard to the formation of the tray 105 from the blank 103, e.g., by positioning the front panel 127 and the back panel 123 in spaced and parallel arrangement, both panels 127, 123 generally upright relative to the bottom panel 121. The top panel 131 can also be in spaced and parallel arrangement with the bottom panel 121

However, after inverting the blank 203 such that the exterior surface 201 is positioned on a supporting surface and such that the interior surface of the blank 203 is positioned facing upwardly, formation of closed ends 209, 211 of the tray 205 can include folding the end flap 243 at the respective portion of the fold line 145 into at least partial face-to-face contact with a respective portion of the back panel 123, folding the end flap 247 at the respective portion of the fold line 145 into at least partial face-to-face contact with a respective portion of the bottom panel 121, folding the end flap 249 at the respective portion of the fold line 145 into at least partial face-to-face contact with a respective portion of the front panel 127, folding the end flap 255 at the respective portion of the fold line 157 into at least partial face-to-face contact with a respective portion of the back panel 123, folding the end flap 259 at the respective portion of the fold line 157 into at least partial face-to-face contact with a respective portion of the bottom panel 121, and folding the end flap 261 at the respective portion of the fold line 157 into at least partial face-to-face contact with a respective portion of the front panel 123.

Further, formation of the closed ends 209, 211 of the tray 205 can include folding the attachment portion 253 of the end flap 247 at the fold line 252 into at least partial face-to-face contact with the base portion 251 thereof and folding the attachment portion 265 of the end flap 259 at the fold line 267 into at least partial face-to-face contact with the base portion 263 thereof.

The aforementioned arrangement of panels and end flaps can be at least partially maintained with one or more applications of adhesive such as glue G. In particular, the interior surface of the respective distal portions 253, 265 of the respective end flaps 247, 259 can be attached/adhered to the respective end flaps 243, 255, the interior surface of the respective distal portions 181, 183 of the respective end flaps 169, 175 can be attached/adhered to the respective interior surfaces of the end flaps 249, 261, a longitudinally inner portion of the top panel 131 can be attached/adhered to the flange support panel 135, and a longitudinally outer portion of the top end panel 131 can be attached/adhered to the flange support panel 139.

As the tray 205 is formed from the blank 203, the end flaps 169, 177 can be folded downwardly at the respective fold lines 173, 177 into the interior 207 of the tray 205. Such movement of the end flaps 169, 177 can cause the respective end flaps 249, 261 attached thereto to fold at respective portions of the respective fold lines 145, 157 away from the interior 207 of the tray 205.

The blanks may then be coated with a varnish to protect any information printed on the blank. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. 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 blanks can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the trays, to function at least generally as described above. The blanks can also be laminated to 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 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 spaced apart slits to be replaced with a continuous slit, a continuous score, 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. Also, a tear line can be a series of cut scores passing completely, or partially, through the material, that are separated by nicks.

The term “glue” is intended to encompass all manner of adhesives commonly used to secure tray panels in place.
