DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS 100171 The present disclosure generally relates to reinforced packages for holding products such as food products or other articles. Packages according to the present disclosure can accommodate articles of any shape. [00181 Fig. 1 illustrates a reinforced package generally indicated at 1, according to a first embodiment of the disclosure. The package includes a bag 3 and a reinforcing sleeve 5 attached to the bag 3. The bag has an open end 7, a closed end 9, and an interior space 17 for holding a product. The interior space 17 may be accessible through a notch 15 in the bag 3. The reinforcing sleeve 5 is configured to at least partially receive a portion 11 of the closed end 9 of the bag 3. 10019] As illustrated in Fig. 2, a blank 10 for forming the reinforcing sleeve 5 has a lateral axis Li and a longitudinal axis L2. In the illustrated embodiment, the blank 10 has a front panel 21 foldably connected to a first side panel 28 at a first arcuate fold line 33. The first side panel 28 includes two individual panel portions 28A, 28B foldably connected to one another at lateral fold line 26. A first back panel 23 is foldably connected to the first side panel 28 at a second arcuate fold line 31. A second side panel 29 is foldably connected to the front panel 21 at a third arcuate fold line 35. The second side panel 29 includes two individual panel portions 29A, 29B foldably connected to one another at lateral fold line 27. A second back panel 25 is foldably connected to the second side panel 29 at a fourth arcuate fold line 37. As illustrated, the arcuate fold lines 31, 33 are spaced apart from lateral fold line 26. Similarly, the arcuate fold lines 35, 37 are spaced apart from lateral fold line 27. In 2 WCSR 7695409vl WO 2014/142893 PCT/US2013/031451 alternative embodiments, the blank 10 can have alternative panel, fold line, and/or panel portion arrangements. [00201 In the illustrated embodiment, the blank 10 can include one or more adhesive regions 41, 43, and 45 on the first back panel 23, front panel 21, and/or second back panel 25, respectively, for receiving adhesive and being fixedly attached to an exterior surface of the bag 3. Furthermore, the blank 10 has a first edge 52 and a bottom edge 53 extending in the longitudinal direction L2. In one embodiment, the adhesive regions 41, 43, 45 are separated from the first edge 52 by a first distance DI and are separated from the bottom edge 53 by a second distance D2. In one embodiment, the first distance DI is less than the second distance D2. The first and second side panels 28, 29 and regions separate from the adhesive regions 41, 43, 45 may be generally free from adhesive in some embodiments, or may include adhesive in alternative embodiments. Additionally, the first and second distances Dl, D2, adhesive regions 41, 43, 45, and/or edges 52, 53 can be otherwise arranged, shaped, modified, or omitted without departing from the scope of this disclosure. 100211 Generally, the blank 10 may be folded about fold lines 26, 27 to create the reinforcing sleeve 5. For example, distal ends 55, 57 of the first and second back panels 23, 25 may be overlapped, and the sleeve 5 attached to the bag 3 as illustrated in Figs. 1, 3, and 4. The individual panel portions 28A, 28B, 29A, and 29B may be in face-to-face registration in a first, non-erect position of the bag 3 as illustrated in Fig. 1. The first, non-erect position illustrated reduces and/or minimizes a volume of the interior space 17 such that the package 1 is in a non-erect or flattened state. The non-erect state may facilitate easy stacking of a plurality of packages into, for example, a shipment container and subsequent organization at a destination facility. The individual panel portions 28A, 28B, 29A, and 29B may be flexed or positioned to form first and second sides 58, 59 of the package I in a second, erect position of the bag 3 as illustrated in Figs. 3-4. The second, erect position illustrated increases and/or maximizes a volume of the interior space 17 such that the package 1 is in an erect or self supporting state. The closed end 9 of the bag 3 can extend upwardly into an interior 56 of the sleeve 5 in the direction of arrow Al while the package is in the erect state (Fig. 3). Furthermore, the bottom edge 53 forms a support when the package 1 is in the erect state for contacting a surface S (Fig. 4). The support formed of the bottom edge 53 maintains the package in an upright position on the surface S. As further illustrated in Figs. 3-4, gusseted sides 60 of the bag 3 may be maintained extended when the package 1 is in the erect state. Other intervening states of the package I including intermediate states whereby the package 1 is not fully erected are also applicable according to some embodiments. Furthermore, additional reinforcing sleeves of differing configurations are also applicable according to some embodiments. [00221 For example, turning to Fig. 5, a reinforced package generally indicated at 61 is illustrated, according to a second embodiment of the disclosure. The package 61 includes the bag 3 and a reinforcing sleeve 6 attached to the bag 3. The reinforcing sleeve 6 is configured to at least partially receive a portion 11 of the closed end 9 of the bag 3. 3 WCSR 7695409vl WO 2014/142893 PCT/US2013/031451 [00231 As illustrated in Fig. 6, a blank 70 for forming the reinforcing sleeve 6 has a lateral axis LI and a longitudinal axis L2. In the illustrated embodiment, the blank 70 has a front panel 71 foldably connected to a first side panel 78 at a first arcuate fold line 83. The first side panel 78 includes two individual panel portions 78A, 78B foldably connected to one another at lateral fold line 76. A first back panel 73 is foldably connected to the first side panel 78 at a second arcuate fold line 81. A second side panel 79 is foldably connected to the front panel 71 at a third arcuate fold line 85. The second side panel 79 includes two individual panel portions 79A, 79B foldably connected to one another at lateral fold line 77. A second back panel 75 is foldably connected to the second side panel 79 at a fourth arcuate fold line 87. As illustrated, the arcuate fold lines 81, 83 converge at one end of the lateral fold line 76 and are spaced apart at another end of the lateral fold line 76. Similarly, the arcuate fold lines 85, 87 converge at one end of the lateral fold line 77 and are spaced apart at another end of the lateral fold line 77. In alternative embodiments, the blank 70 can have alternative panel, fold line, and/or panel portion arrangements. 100241 In the illustrated embodiment, the blank 70 can include one or more adhesive regions 91, 93, and 95 on the first back panel 73, front panel 71, and/or second back panel 75, respectively, for receiving adhesive and being fixedly attached to an exterior surface of the bag 3. Furthermore, the blank 70 has a first edge 102 and a bottom edge 103 extending in the longitudinal direction L2. In one embodiment, the adhesive regions 91, 93, 95 are separated from the first edge 102 and the bottom edge 103. The first and second side panels 78, 79 and regions separate from the adhesive regions 91, 93, 95 may be generally free from adhesive in some embodiments, or may include adhesive in alternative embodiments. Additionally, adhesive regions 91, 93, 95, and/or edges 102, 103 can be otherwise arranged, shaped, modified, or omitted without departing from the scope of this disclosure. 100251 Generally, the blank 70 may be folded about fold lines 76, 77 to create the reinforcing sleeve 6. For example, distal ends 105, 107 of the first and second back panels 73, 75 may be overlapped, and the sleeve 6 attached to the bag 3 as illustrated in Figs. 5 and 7. The individual panel portions 78A, 78B, 79A, and 79B may be in face-to-face registration in a first, non-erect position of the bag 3 as illustrated in Fig. 5. The first, non-erect position illustrated reduces and/or minimizes a volume of the interior space 17 such that the package 1 is in a non-erect or flattened state. The non-erect state may facilitate easy stacking of a plurality of packages into, for example, a shipment container and subsequent organization at a destination facility as described with reference to the first embodiment. The individual panel portions 78A, 78B, 79A, and 79B may be flexed or positioned to form first and second sides 108, 109 of the package 1 in a second, erect position of the bag 3 as illustrated in Fig. 7. The second, erect position illustrated increases and/or maximizes a volume of the interior space 17 such that the package 1 is in an erect or self-supporting state as illustrated in Fig. 7. The closed end 9 of the bag 3 can be entirely received by the sleeve 6 in the illustrated embodiments. Furthermore, the front panel 71 and the overlapped first and second back panels 73, 75 converge on the bottom edge 103 allowing the entire package 7 to be inclined on the surface S in a fully-maintained erect state. As 4 WCSR 7695409vl WO 2014/142893 PCT/US2013/031451 further illustrated in Fig.7, gusseted sides 60 of the bag 3 may be maintained extended when the package 7 is in the erect state. Other intervening states of the package 7 including intermediate states whereby the package 7 is not fully erected are also applicable according to some embodiments. Furthermore, additional bags of differing configurations are also applicable according to some embodiments. 100261 For example, Fig. 8 is a perspective view of an alternative reinforced package 111, according to a third embodiment of the disclosure. The package includes a bag 113 and either the reinforcing sleeve 5 or 6 attached to the bag 113. The bag 113 has an open end 107, a closed end 109, and an interior space 117 for holding a product. The interior space 117 may be accessible through a flap 115 in the bag I13.The bag 113 may also include gusseted sides 119 which may be maintained in an erect position through use of the reinforcing sleeves 5, 6 as described above.
