The container 5 can be used to hold a food product P (Fig. 5), such as a meat product that can be frozen or unfrozen. The container 5 may hold other types of food products without departing from the disclosure. In use, the container 5 may be tipped or raised at an angle to better display the food product P, such as in a retail grocery store or other location. In such instances, fluids F, e.g., melted ice or other runoff from the food product P, or other fluids from the environment such as condensation, can travel across portions of the container 5 under the influence of gravity. The protective strip 6 minimizes, inhibits, and/or prevents such fluids in the container 5 from being absorbed into the material of the container 5 through the uncoated edge E of the container 5. As noted below, the container 5 and protective strip 6 can have other features as shown and/or described herein. Figs. 4 and 5 illustrate the container 5 in in the form of a tray in accordance with the disclosure and having an interior surface 7, a bottom wall 11, two side walls 13, 15, and two end walls 17, 19. In the illustrated embodiment, the container 5 has four corners 23, 25, 27, 29 connecting respective side walls 13, 15 and end walls 17, 19. A flange 21 extends outwardly from the side walls 13, 15, end walls 17, 19, and corners 23, 25, 27, 29, and extends around the perimeter of the container 5. The side walls 13, 15 and the end walls 17, 19 extend from the bottom wall 11, and one or more of the side walls 13, 15 and the end walls 17, 19 cooperate with the bottom wall 11 to at least partially define a cavity 22 of the container 5. In particular, an interior surface 7 (Fig. 3) of the container 5 along the side walls 13, 15, the end walls 17, 19, the bottom wall 11, and the flange 21 to form the cavity 22. The cavity 22 is for holding the food product P and/or another article. Referring additionally to Fig. 3, in one embodiment, the container 5 comprises material similar to the material disclosed in the '443 patent in that the container 5 comprises a base layer or laminate material 8 comprising two layers of paperboard 76, 78. In this regard, the side walls 13, 15, the end walls 17, 19, the corners 23, 25, 27, 29, and the flange 21 of the container 5 comprise the base layer 8. The layers of paperboard 76, 78 can be attached by a layer of adhesive 84, as shown. A waterproof coating 80 is disposed on the face of the upper layer of paperboard 76, and a moisture- proof coating 82 is disposed on the face of the lower layer of paperboard 78. In this regard, the waterproof coating 80 forms the interior surface 7 of the container 5 and can comprise various suitable waterproof coatings such as polyethylene extrusion coating or other suitable waterproof coatings. The moisture-proof coating 82 can be, for example, a water-based acrylic aqueous coating, and provides a moisture-proof barrier on the bottom of the container 5 and forms the exterior surface 9 of the container 5. The moisture-proof coating 82 can be any suitable material that is resistant to fluids F (Fig. 5), for example, moisture, but not waterproof. In embodiments, the container 5 could comprise a single layer of paperboard without departing from the disclosure, and/or one or more of the layers 76, 78 could be materials other than paperboard without departing from the disclosure. In the illustrated embodiment, the coatings 80, 82 are not disposed on the edge E such that the edge E is an uncoated portion of the base layer 8. As shown, the container 5 includes a protective strip 6 attached to a portion of the container 5 that includes a portion of the bottom wall 11, the side wall 13, and the corners 23, 25. In this regard, the protective strip 6 is attached to both the interior surface 7 and the exterior surface 9 of the container 5 and overlies at least a portion of the edge E along the side wall 13 and corners 23, 25, and a portion of the end walls 17, 19 to provide a protective seal on the edge E. While the protective strip 6 is illustrated extending past the edge E of the container 5, in embodiments, the protective strip 6 can be crimped or overlapped near the edge E of the container 5.

[0021] Referring to Fig. 1, a blank 53 for forming the container or tray 5 (Fig. 4) is illustrated. The blank 53 has corresponding portions that are formed into the side walls 13, 15, end walls 17, 19, corners 23, 25, 27, 29 and the flange 21 that extends around the perimeter of the blank 53 and the container 5. The corner portions 23, 25, 27, 29 of the blank 53 have score lines 55 to facilitate the forming of the corners 23, 25, 27, 29 during the forming, for example, press-forming, of the blank 53 into the container 5. In one embodiment, the blank 53 comprises the two layers of paperboard 76, 78, the waterproof coating 80 that forms the interior surface 7 of the blank 53 and the container 5, and the moisture resistant-coating 82 that forms the exterior surface 9 (Fig. 3) of the blank 53 and the container 5. The edge E of the blank 53 corresponds with the edge E of the container 5 and extends around the perimeter of the blank 53. As shown in Fig. 3, the coatings 80, 82 do not extend between the interior surface 7 and the exterior surface 9 of the blank 53 such that the edge E of the blank 53 is exposed or uncoated. The blank 53 could have other features and materials without departing from the disclosure.

[0022] As shown in Figs. 2 and 3, the protective strip 6 is attached to a portion of the blank 53 so that the protective strip 6 covers a portion of the interior surface 7, a portion of the exterior surface 9, and the edge E. In this regard, the protective strip 6 can be wrapped around a portion of the interior surface 7 and the exterior surface 9 of the blank 53. In other embodiments, separate protective strips 6 can be applied to the respective interior surface 7 and exterior surface 9 of the blank 53. In one embodiment, the protective strip 6 covers the side wall 13, the corners 23, 25, and the flange 21 that extends around the side wall 13 along the interior surface 7 and the exterior surface 9 of the blank 53. The protective strip 6 can be alternatively configured to cover more of the edge E such as the edge of the side wall 15 and the corners 27, 29 without departing from the disclosure. In embodiments, the protective strip 6 can cover the entirety of the edge E without departing from the disclosure, or the protective strip 6 can cover less of the edge E than illustrated without departing from the disclosure.

[0023] The protective strip 6 can comprise a polymer liner that comprises a material such as polyethylene film (e.g., PET or polyethylene terephthalate film) or other polymer film or any other suitable material that can be adhered to the blank 53, e.g., along portions that form the flange 21 and/or the side walls 17, 19 of the container 5 (Fig. 4) and at least partially overlie or cover the edge E to seal the edge E and prevent fluids F, such as moisture, from being transmitted onto and/or into the edge E. In this regard, the protective strip 6 minimizes, inhibits, and/or prevents fluids F, such as moisture, from being absorbed into the paperboard layers 76, 78 at the edge E. The protective strip 6 can be otherwise shaped, arranged, and/or configured without departing from this disclosure.

[0024] As shown in Figs. 5 and 6, the container 5 includes a cover or lid 91 that comprises packaging film, e.g., a thin plastic or other polymeric layer, that covers the container 5 and is wrapped around the container 5 and seals the container 5 to preserve and protect the food product P contained in the cavity 22 of the container 5. In one embodiment, the cover 91 is in at least partial face-to-face contact with the flange 21 such that the cover 91 completely covers the flange 21 and extends around and covers at least a portion of the exterior surface 9 of the container 5 so that the cover 91 seals the container 5. Any plastic or polymeric film, such as polyethylene, polypropylene, polyethylene terephthalate, polyvinylchloride, polyamide, and ethylene vinyl alcohol, or other suitable material, can be used. Any other suitable material can be used for forming the cover 91 that seals the food product P in the cavity 22 of the container 5. Further, alternative lid materials can be used in combination with adhesives that can be used between the cover 91 and the sealing surface of the flange 21 or other surfaces of the container 5 without departing from the disclosure. Further, the cover 91 can be otherwise shaped, arranged, configured, or omitted without departing from the disclosure.

[0025] Fig. 6 shows a schematic of a system 101 and associated method or process for forming the container 5 with the protective strip 6 from the blank 53 according to one exemplary embodiment of the disclosure. As shown, a blank 53 is fed from a stack S of blanks 53 in a feeder 103 to a conveyor assembly 104 that conveys the blanks 53 in a direction of travel 105. The conveyor assembly 104 can include spaced-apart lugs 106 attached to a respective belt 108 that engage the blanks 53 and move the blanks 53 through the system 101. The blanks 53 are first fed below a supply 109 of poly film 110 that is folded around the blank 53 at the folding station 111. Once the film 110 is folded around the blank 53 to seal at least a portion of the edge E of the blank 53 as described herein, the blank 53 and the film 110 pass to a sealing station 113. At the sealing station, the film 110 is sealed to the interior (top) surface 7 (Fig. 3) and the exterior (bottom) surface 9 (Fig. 3) of the blank 53. In one embodiment, the sealing station 113 includes an upper sealer 115 and a lower sealer 117. The blank 53 with the sealed film 110 then passes to a cutting station 119 for cutting the folded and sealed film 110. In one embodiment, the cutting station 119 includes a rotary sealer and cutting mechanism 121, though the cutting station 119 could be otherwise configured without departing from the disclosure. In embodiments, the cut film 110 can be crimped or overlapped near the edge E of the container 5. After the film 110 has been cut at the cutting station 119, the blanks 53 with the protective strip 6 are ready to be press-formed into the container 5. In one embodiment, a tool 125 can be used to form the blank 53 with protective strip 6 into the form of the container 5. The tool 125 can include a female tool assembly 127 and a male tool assembly 129 that press the blank 53 and protective strip 6 into the container 5. The tool 125 could be otherwise shaped, arranged, and configured without departing from the disclosure.

[0026] After forming the container 5, and referring again to Fig. 5, the food product P can be placed in the cavity 22 of the container 5 and the cover 91 is placed over and around the container 5 to seal the food product P in the container 5, for example, to maintain freshness or another desired state of the food product P. As noted above, when the container 5 with food product P that can be frozen, can be typically displayed in an angled orientation for displaying the food product P to the customer. In this regard, the cover 91 may be transparent such that the food product P is visible through the cover 91 in such an orientation. When the food product P thaws, fluid F such as moisture can accumulate in the cavity 22 of the container 5 and will collect near the sealed edge E wherein the protective strip 6 is located. In this regard, the protective strip 6 provides a barrier that covers the edge E and minimizes, inhibits, and/or prevents fluid F from passing into the uncoated paperboard layers 76, 78 at the uncoated or exposed edge E. Accordingly, the strength and integrity of the material of the container 5 is maintained by the presence of the protective strip 6 and the minimization, inhibition, and/or prevention of fluid F such as moisture entering the paperboard layers 76, 78. As noted above, the container 5, protective strip 6 and other features could be otherwise shaped, arranged, and/or configured without departing from the disclosure.

[0027] In some embodiments, and with reference to Fig. 3, the base layer 8 could include a single layer of paperboard, or more than two layers of paperboard, without departing from the disclosure. Further, the waterproof coating 80 could be any suitable coating to prevent fluid such as water or moisture from passing directly from the interior surface 7 of the container 5 (Fig. 4) into the paperboard layers 76, 78. Also, the moisture-resistant coating 82 could be any suitable coating to that resists fluid or moisture absorption into the base layer 8. In embodiments, the moisture-resistant coating 82 could be omitted or could be inherent in the properties of the paperboard layer 78 without departing from the disclosure.

[0028] It is understood that the base layer 8 for the blank 53 (Fig. 1) can be formed by any suitable process such as disclosed in the '443 patent or any other process. The container 5 (Fig. 4) can be formed from the blank 53 by press forming the container 5 by a forming tool or by any suitable process such as disclosed in the '443 patent or any other process. Also, the blank 53 and the container 5 could be alternatively shaped (e.g., circular, oval, rectangular, annular, irregular, etc.) without departing from the scope of this disclosure. [0029] Any of the features of the various embodiments of the disclosure can be combined with, replaced by, or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure.

[0030] Optionally, one or more portions of the blank or other constructs described herein or contemplated hereby may be coated with varnish, clay, or other materials, either alone or in combination. The coating may then be printed over with product advertising or other information or images.
