     DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS 
     The present disclosure generally relates to a carton for receiving and/or holding products to form a package. Cartons according to the present disclosure can accommodate articles of any shape. The carton can be of varying widths and can form multiple compartments in the interior of the carton. In some embodiments, the carton can enclose the compartments in the interior of the carton. In some embodiments the compartments of the carton can be configured for receiving and/or holding articles that are sent to a consumer. The articles can be made from materials suitable in composition for packaging the particular product, and the materials include, but are not limited to, paper materials, aluminum and/or other metals; glass; plastics such as PET, LDPE, LLDPE, HDPE, PP, PS, PVC, EVOH, and Nylon; and the like, or any combination thereof. 
     Cartons according to the present disclosure can accommodate articles of any shape. For the purpose of illustration and not for the purpose of limiting the scope of the disclosure, the following detailed description describes packages of razor cartridges and printed articles (e.g., pamphlets, booklets, flyers, cards, etc.) as disposed within the carton embodiments. In this specification, the terms “inner,” “interior,” “outer,” “exterior,” “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright cartons. 
       FIG. 1  illustrates a blank  100  for forming a carton generally indicated at  101  ( FIGS. 5, 8A , and  8 B) according to a first exemplary embodiment of the disclosure. The carton  101  can be used to house a plurality of articles such as containers C and/or a printed article P ( FIGS. 3A-4 and 7 ) in respective compartments  103 ,  105  ( FIGS. 2-4, 6B, and 7 ). In one embodiment, the containers C can be rectangular (e.g., substantially rectangular or generally rectangular trays), each with a plurality of slots holding respective replacement razor cartridges for a cartridge razor system. Alternatively, the containers C could have any suitable shape or configuration for holding any suitable product. In one embodiment, the printed article P can include pamphlets, booklets, flyers, cards, and/or other suitable materials. The carton  101  could be configured for receiving any suitable number of the containers C and/or printed articles P in any suitable combination. In some embodiments, a package  107  including the carton and the articles (e.g., the containers C and/or printed articles P) held therein, can at least partially comply with particular United States Postal Service&#39;s mailing standards such as for packages intended for automated processing (e.g., automation flats, flat-size mailpieces, etc.) and/or other shipping and/or storage standards and/or requirements. For example, the carton  101  can include axial flexibility features  109  for allowing the package  107  to bend and/or flex a certain degree when passing through the U.S. Postal Services sorting machinery.

As shown in  FIG. 1 , the tear strips  159   a ,  159   b  can include fold lines  167  that are aligned with the score  153  and can be considered extensions of the score  153  in some embodiments. 
     In the illustrated embodiment, the opening features  111  also can include tear lines or perforations for facilitating the separation of the compartments  103 ,  105  from one another and/or from a remainder of the carton  101  as described in more detail below. As shown in  FIG. 1 , the opening features  111  can include a lateral tear line  169  and two longitudinal tear lines  171   a ,  171   b  extending in the back panel  121 . In one embodiment, the lateral tear line  169  can be spaced from the score  153  and can extend from the longitudinal fold line  125   a  to the longitudinal fold line  125   b . In one example, the lateral tear line  169  can be aligned (e.g., substantially aligned or generally aligned) with tear lines  161  of the tear strips  159   a ,  159   b  in the front panels  131   a ,  131   b . As shown in  FIG. 1 , the longitudinal tear lines  171   a ,  171   b  can be spaced apart from the score  151  and can extend from the lateral tear line  169  to the lateral fold line  129   b . In addition to the tear lines  169 ,  171   a ,  171   b , the lateral fold line  129   b  can be a tear line for separating the second end panel  127   b  and the second cover panel  147   b  from the compartments  103  as described in more detail below. The opening features, including any of the tear strips  157 ,  159   a ,  159   b , the tear lines  169 ,  171   a ,  171   b , and/or the tear line/fold line  129   b , could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     In the illustrated embodiment, the package  107  can be formed as shown in  FIGS. 2-5 . In one embodiment, the blank  100  can be positioned with the coated and/or printed (e.g., clay-coated side) facing upwardly, and the blank  100  can be folded along at least the longitudinal fold lines  133   a ,  133   b ,  141   a ,  141   b  to overlap the back panel  121  and the side panels  123   a ,  123   b  with the front panels  131   a ,  131   b  and the divider panels  135   a ,  135   b  and to position the attachment flaps  139   a ,  139   b  between the back panel  121  and the respective front panels  131   a ,  131   b  as shown in  FIG. 2 . In the illustrated embodiment, glue (e.g., in the form of glue strips G 1  shown schematically in  FIG. 1 ) can be applied to the attachment flaps  139   a ,  139   b  and/or the back panel  121  (e.g., prior to folding the blank  100 ) so that the attachment flaps  139   a ,  139   b  are glued to the back panel  121  when the attachment flaps  139   a ,  139   b  are positioned in face-to-face contact with the back panel  121  ( FIG. 2 ). As shown in  FIG. 2 , the fold lines  141   a ,  141   b  can extend along (e.g., in contact with, adjacent, and/or proximate to) the longitudinal tear lines  171   a ,  171   b  when the attachment flaps  139   a ,  139   b  are glued to the back panel  121 . 
     As shown in  FIGS. 3A and 3B , the side panels  123   a ,  123   b , the front panels  131   a ,  131   b , and the divider panels  135   a ,  135   b  can be folded along the longitudinal fold lines  125   a ,  125   b ,  133   a ,  133   b ,  137   a ,  137   b ,  141   a ,  141   b  to at least partially form the compartments  103 ,  105  with portions of the panels  121 ,  123   a ,  123   b ,  131   a ,  131   b ,  135   a ,  135   b  and the attachment flaps  139   a ,  139   b  extending around respective interior spaces  173  of the respective compartments  103 ,  105 . For example, a portion of the first side panel  123   a , a section of the first front panel  131   a  defined by the tear strip  159   a , the first divider panel  135   a , the first attachment flap  139   a , and a section of the back panel  121  defined by the lateral tear line  169 , the longitudinal tear line  171   a , and the fold lines  125   a ,  129   b  extend along the interior space  173  of one of the compartments  103  (e.g., the first interior space of the first compartment). Similarly, a portion of the second side panel  123   b , a section of the second front panel  131   b  defined by the tear strip  159   b , the second divider panel  135   b , the second attachment flap  139   b , and a section of the back panel  121  defined by the lateral tear line  169 , the longitudinal tear line  171   b , and the fold lines  125   b ,  129   b  extend along the interior space  173  of the other one of the compartments  103  (e.g., the second interior space of the second compartment). In the illustrated embodiment, a tear-away section  175  of the back panel  121  can be defined by the tear lines  169 ,  171   a ,  171   b ,  129   b  extending between the compartments  103 . In addition, portions of the side panels  123   a ,  123   b , sections of the front panels  131   a ,  131   b  defined by the respective tear strips  159   a ,  159   b , and a section of the back panel  121  defined by the lateral tear line  169  and the fold lines  125   a ,  125   b ,  129   a  can extend along the interior space  173  of the compartment  105  (e.g., the third interior space of the third compartment). The compartments  103 ,  105  could be otherwise formed and/or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     As shown in  FIGS. 3A and 3B , the articles C, P can be loaded into the interior spaces  173  of the respective compartments  103 ,  105 . In the illustrated embodiment, the containers C can be inserted into the interior spaces  173  of the respective compartments  103 . In one embodiment, the containers C can fit tightly in the compartments  103  to help prevent the containers C from unintentionally sliding out of the compartments  103  but allowing the containers C to be pushed into or pulled out of the compartments  103 . As shown in  FIG. 3B , the entire container C fits in the interior space  173  of the compartment  103  (e.g., from the opening of the compartment  103  adjacent the fold line  129   b  to the tear strip  159   a ,  159   b ); however, in alternative embodiments, portions of the containers C can extend outside the compartment  103 . The printed article P can be at least partially inserted into the interior space  173  of the compartment  105  as shown in  FIGS. 3B and 4 . In one embodiment, the width of the carton  101  can be at least partially determined by the width of the printed article P, and the carton  101  could be narrower for a smaller printed article P, which could bring the compartments  103  closer together and reduce the size of or eliminate the tear-away section  175 . In some embodiments, the width of the carton  101  can also be at least partially configured for allowing a suitable amount of bending of the carton  101  (e.g., at the flexibility features  109 ). For example, the spacing of the compartments  103  can facilitate bending of the carton  101 . The articles C, P could be otherwise loaded into the compartments  103 ,  105  in any suitable order or simultaneously without departing from the disclosure. 
     As shown in  FIGS. 4 and 5 , the cover panels  147   a ,  147   b  and the end panels  127   a ,  127   b  can be folded to form the carton  101  ( FIG. 5 ). In the illustrated embodiment, the second end panel  127   b  and the second cover panel  147   b  can be folded along the lateral fold lines  129   b ,  149   b  so that the second end panel  127   b  at least partially overlaps the ends of the compartments  103  and the second cover panel  147   b  partially overlaps the front panels  131   a ,  131   b . In one embodiment, glue spots G 2  ( FIGS. 1 and 3B ) can be applied to the front panels  131   a ,  131   b  (and/or to the second cover panel  147   b ) to adhere the second cover panel  147   b  to the front panels  131   a ,  131   b . As shown in  FIG. 4 , the end flaps  143   a ,  143   b  can be folded along the lateral fold lines  145   a ,  145   b  to partially overlap the end of the compartment  105  and the first end panel  127   a  and the first cover panel  147   a  can be folded along the lateral fold lines  129   a ,  149   a  so that the first end panel  127   a  at least partially overlaps the end flaps  143   a ,  143   b  and the end of the compartment  105  and the first cover panel  147   a  partially overlaps the front panels  131   a ,  131   b  and the second cover panel  147   b . In one embodiment, a glue strip G 3  can be applied to the first cover panel  147   a  ( FIG. 1 ) and/or a glue strip G 3 ′ can be applied to the second cover panel  147   b  ( FIG. 4 ) to adhere the cover panels  147   a ,  147   b  together when the carton  101  is closed ( FIG. 5 ). Further, glue spots G 4  ( FIGS. 1 and 4 ) can be applied to the front panels  131   a ,  131   b  (and/or to the first cover panel  147   a ) to adhere the first cover panel  147   a  to the front panels  131   a ,  131   b.    
     As shown in  FIG. 5 , with the cover panels  147   a ,  147   b  overlapped and secured, at least the end panels  127   a ,  127   b  can close the ends  181   a ,  181   b  of the carton  101  and at least the back panel  121 , the side panels  123   a ,  123   b , the end panels  127   a ,  127   b , and the cover panels  147   a ,  147   b  can extend around an interior  183  ( FIG. 6A ) of the carton  101 . In the illustrated embodiment, the carton  101  with the articles C, P contained therein as shown in  FIG. 5  can form the package  107 . As shown in  FIG. 5  and in  FIGS. 8A and 8B  (as described in more detail below), the flexibility features  109  (including the longitudinal score line  151 , the lateral score line  153 , the oblique scores  155 , and/or portions of the tear strip  157 ) can be arranged along (e.g., approximately along, generally along, substantially along, etc.) the axes of the carton  101  for allowing the package  107  to bend according to the United States Postal Service&#39;s standards for flat-size mailpieces as described in more detail below. The carton  101  and the package  107  could be otherwise formed without departing from the disclosure. 
     As shown in  FIGS. 6A-7 , the carton  101  can be opened and the compartments  103 ,  105  can be separated to break up the package  107  and to allow access to the articles C, P in the compartments  103 ,  105 . For example, as shown in  FIG. 6A , the tear strip  157  can be torn away from the first cover panel  147   a  (e.g., by grasping the start tab  163  and pulling the tear strip  157  apart from the first cover panel  147   a ). In one embodiment, at least partially removing the tear strip  157  can expose the tear strips  159   a ,  159   b  in the front panels  131   a ,  131   b  in the interior  183  of the carton  101 . As shown in  FIG. 6A , the tear strips  159   a ,  159   b  can be torn away from the front panels  131   a ,  131   b  (e.g. by grasping the start tabs  163  and pulling the tear strips  159   a ,  159   b  apart from the front panels  131   a ,  131   b ). As shown in  FIG. 6B , the carton  101  can be torn along the lateral tear line  169  in the back panel  121  and along portions of the side panels  123   a ,  123   b  to at least partially separate the compartment  105  from the remainder of the carton  101  (e.g., including at least the second cover panel  147   b , the compartments  103 , and the tear-away section  175 ). Also as shown in  FIG. 6B , the second cover panel  147   b  and the second end panel  127   b  can be separated from the compartments  103  and the tear-away section  175 , such as by grasping the second cover panel  147   b  at an edge, pulling the second cover panel  147   b  upwardly away from the front panels  131   a ,  131   b  (e.g., separating the glue spots G 2 ) and tearing the second end panel  127   b  away from the back panel  121  along the tear line  129   b . In addition, the tear-away section  175  can be removed from the compartments  103  by tearing along the tear lines  171   a ,  171   b  ( FIGS. 1 and 2 ). As shown in  FIG. 7 , the articles C, P can be removed from the separate compartments  103 ,  105  as desired. The package  107  could be otherwise opened and/or the compartments  103 ,  105  could be otherwise separated without departing from the disclosure. For example, any or all of the articles C, P could be removed from the compartments  103 ,  105  before and/or during the separation of the compartments  103 ,  105 . Alternatively, the carton  101  could be opened and the articles C, P could be removed without separating the compartments  103 ,  105 . 
     In one embodiment, the package  107  can at least partially comply with flexibility standards for United States Postal Service flat-size mailpieces (e.g., the Mailing Standards of the United States Postal Service Domestic Mail Manual 201.4.3 and/or other standards) and/or other shipping, mailing, storage, etc. standards and/or requirements. For example, as shown in  FIG. 8A , the package  107  can bend along at least the longitudinal score  151  extending in the back panel  121 , the end panels  127   a ,  127   b , and the cover panels  147   a ,  147   b . In one embodiment, the oblique scores  155  in the end panels  127   a ,  127   b  can help the end panels  127   a ,  127   b  deform as the package  107  is flexed. Similarly, as shown in  FIG. 8B , the package  107  can bend along the axis that is transverse to the longitudinal score  151 . For example, the package  107  can bend along the lateral score  153  extending in the back panel  121  and the side panels  123   a ,  123   b  and along portions of the tear strip  157  in the front panel  157 . In one embodiment, the front panels  131   a ,  131   b  in the interior  183  of the carton  101  can also bend along portions of the tear strips  159   a ,  159   b  (e.g., along the fold lines  167 ). In one embodiment, the oblique scores  155  in the side panels  123   a ,  123   b  can help the side panels  123   a ,  123   b  deform as the package  107  is flexed. As shown in  FIG. 8B , the back panel  121  can bend along the lateral score  153  and/or the tear line  169  in one embodiment. The package  107  could otherwise bend or flex or could be less capable of flexing and/or bending without departing from the disclosure.

In one embodiment, gluing the end flaps  343  to the end panels  327   a ,  327   b  can cause the blank  300  to fold along the fold lines  329   a ,  329   b  so that the end panels  323   a ,  323   b  extend over the ends of the carton, the first end panel  329   a  at least partially closing the ends of the compartments  303  and the second end panel  329   b  at least partially closing the end of the compartment  305 . As shown in  FIG. 11 , the side panels  323   a ,  323   b  and the end panels  327   a ,  327   b  can be folded to extend obliquely (e.g. upwardly and inwardly) from the back panel  321 . The second cover panel  347   b  can be folded along the lateral fold line  349   b  and can be positioned to overlap the front panels  331   a ,  331   b . In one embodiment, the second cover panel  347   b  can be glued in face-to-face contact with the front panels  331   a ,  331   b  (e.g., at glue spots G 7 ). In one embodiment, the second cover panel  347   b  can extend along the interior  374  and can at least partially close the compartment  305 . Subsequently, the first cover panel  347   a  can be folded along the lateral fold line  349   a  to at least partially overlap the second cover panel  347   b  and can be glued in face-to-face contact with the second cover panel  347   b  (e.g., along glue strip G 8 ). The carton  301  and/or the package  307  could be otherwise formed without departing from the disclosure. 
     In one embodiment, the package  307  can be flexed and/or bent in a similar manner as the package  107  of first embodiment (e.g., for at least partially complying with flexibility standards for United States Postal Service flat-size mailpieces). 
     As shown in  FIG. 12 , the package  307  can be at least partially opened by tearing the tear strip  157  in the first cover panel  347   a  and pulling the second cover panel  347   b  upwardly away from the front panels  331   a ,  331   b . Separating the second cover panel  347   b  from the front panels  331   a ,  331   b  can include tearing along the glue spots G 7  ( FIG. 12 ). In one embodiment, with the carton  301  in the open configuration of ( FIG. 12 ), the articles C can be removed from the interior spaces  373  of the compartments  303  and the article P can be removed from the recess  374  of the compartment  305 .

As shown in  FIG. 13 , the side panels  523   a ,  523   b  and the longitudinal fold lines  525   a ,  525   b ,  533   a ,  533   b  are interrupted by side openings  565  in the blank  500 . In the illustrated embodiment, the side openings  565  are aligned with the lateral scores  553  of the flexibility feature  509  and the lateral tear line  169  in the back panel  521 . As shown in  FIG. 13 , attachment flaps  539   a ,  539   b  can be similar to the attachment flaps  139   a ,  139   b  of the first embodiment, except that the first attachment flap  539   a  is larger. The side panels  523   a ,  523   b , the front panels  531   a ,  531   b , the side openings  565 , and/or the attachment flaps  539   a ,  539   b  could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     In the embodiments shown in  FIGS. 1 and 9 , the front panels  131   a ,  131   b  of the blank  100  and the front panels  331   a ,  331   b  of the blank  300  are symmetric (e.g., the first front panels  131   a ,  331   a  are mirror images of the second front panels  131   b ,  331   b ). As shown in  FIG. 13 , the portions of the front panels  531   a ,  531   b  that form the compartment  505  ( FIG. 16 ) are different in the blank  500 . The first front panel  531   a  includes an enlarged portion  585   a  that has a width (in the lateral direction L 3 ) that is similar to or the same as the width (e.g., in the lateral direction L 3 ) of the back panel  521  and the second front panel  531   b  has a smaller attachment portion  585   b  that is sized to receive a glue strip G 1 ′ ( FIG. 13 ) for attachment to the enlarged portion  585   a  of the first front panel  531   a . In one embodiment, a window  587  can extend in the enlarged portion  585   a  of the first front panel  531   a  so that the article P is visible through the first front panel  531   a  when the carton  501  is formed ( FIGS. 16 and 17 ). In an exemplary embodiment, the edge of the window  587  in the enlarged portion  585   a  can have convex curved portions at the corners of the windows to accommodate locations  589  (schematically indicated by circles on the blank  500 ). In one embodiment, the locations  589  can provide engagement areas where suction cups (not shown) can engage the first front panel  531   a  during an automated assembly process (e.g., as described in more detail below. The portions  585   a ,  585   b , the window  587 , and/or the locations  589  could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     As shown in  FIG. 13 , the enlarged portion  585   a  can include a front score  590 , which is part of the flexibility features  509  and is aligned with the longitudinal score  151  when the carton  501  is formed and the front panel is positioned opposite to the back panel  521 . In the illustrated embodiment, two front end flaps  528   a  can be foldably connected to the enlarged portion of the first end panel  531   a  along fold lines  530   a  for cooperating with the end flaps  527   a  for at least partially closing one end of the carton  507 . As shown in  FIG. 13 , the front end flaps  528   a  are spaced apart from one another by a cutout, which can be aligned with the front score  590  of the flexibility features  509 . In addition, front end flaps  528   b  can be foldably connected to the respective front panels  531   a ,  531   b  along fold lines  530   b  opposite to the front end flaps  528   a  for cooperating with the end flaps  527   b  to at least partially close the opposite end of the carton  507 . The front end flaps  528   a ,  528   b  could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     As shown in  FIG. 13 , the front panels  531   a ,  531   b  each include a plurality of perforations  561  (e.g., three lines of perforations  561 , each) that extend in the L 3  direction and are at least partially aligned with the openings  565 , the lateral scores  553 , and the lateral tear line  169 . Accordingly, the lines of perforations  561  can cooperate with the flexibility features  509  for allowing the package  507  to flex as described above with respect to the first embodiment. In one embodiment, at least one of the lines of perforations  561  can form a tear line in the front panels  531   a ,  531   b  for separating the compartments of the package  507 . Any of the lines of perforations  561  could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     In the illustrated embodiment, each of the front panels  531   a ,  531   b  includes a window  591  extending in the portion of the front panels  531   a ,  531   b  the forms the compartments  503  of the carton  507  ( FIG. 16 ). The windows  591  can provide product visibility when the package  507  is formed. As shown in  FIG. 13 , the edges of the windows  591  can include a respective concave curved portion for forming additional locations  589  in the front panels  531   a ,  531   b  for being engaged by suction cups (not shown). In the illustrated embodiment, inner flaps  592  can be foldably connected to the respective front panels  531   a ,  531   b  along the lines of perforations  561  and can extend in the respective windows  591  in the blank  500 . Each of the inner flaps  592  can include an intermediate fold line  593  (e.g., a line of perforations or any other suitable fold line or tear line) that defines a distal portion and a proximal portion. In an exemplary embodiment, the inner flaps  592  can be separable from the respective front panels  531   a ,  531   b  along cut lines  595  and can be held in place by nicks  596  until the nicks are broken when forming the carton  507 . The windows  591  and/or the inner flaps  592  could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     As shown in  FIG. 14 , the envelope blank  600  has a lateral axis L 5  and a longitudinal axis L 6 . In the illustrated embodiment, the envelope blank  600  has a central panel  611  foldably connected to a cover panel  613  along a lateral fold line  615 . In one embodiment, two side attachment flaps  617  are foldably connected to the central panel  611  along respective longitudinal fold lines  619  on opposing sides of the central panel  611 . As shown in  FIG. 14 , an end attachment flap  621  can be foldably connected to the central panel  611  along a lateral fold line  623  at an opposite end of the central panel  611  from the cover panel  613 . In an exemplary embodiment, the end attachment flap  621  can include a tear strip  625  for facilitating opening the envelope  601  formed from the envelope blank  600 . As shown in  FIG. 14 , the envelope blank  600  can include flexibility features  609  similar to the flexibility features  509  for cooperating with the flexibility features  509 . In the illustrated embodiment, the flexibility features  609  can include a longitudinal score  627  extending in the central panel  611 , the cover panel  613 , and the end attachment flap  621  (e.g., along a longitudinal axis of the envelope blank  600 ). The flexibility features  609  further can include a lateral score  629  extending in the central panel  611  and each of the side attachment flaps  617  and a lateral score  631  extending in the cover panel  613 . The envelope blank  600  could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure. 
     According to the illustrated embodiment, the carton  501  can be formed similarly to the cartons of the prior embodiments. For example, glue strips G 1  can be applied to the exterior surfaces of the attachment flaps  539   a ,  539   b  and the glue strip G 1 ′ can be applied to the exterior surface of the attachment portion  585   b  of the second front panel  531   b . In one embodiment, the first attachment flap  539   a  can be folded over the first divider panel  135   a  along the fold line  141   a  and the second attachment flap  539   b  and the second divider panel  135   b  can be folded over the second front panel  531   b  along the fold lines  137   b . Subsequently, the second front panel  531   b  and the second side panel  523   b  can be folded over the back panel  521  along the fold line  525   b  and the first front panel  531   a  can be folded over the first side panel  523   a  and the back panel  521  along the fold line  533   a . As the front panels  531   a ,  531   b  are folded, the attachment flaps  539   a ,  539   b  extend between the front panels  531   a ,  531   b  and the back panel  521  and so that the glue strips G 1  secure the attachment flap  539   a ,  539   b  to the back panel  521  ( FIG. 15 ) when the panels are folded and the partially-formed carton is in a flattened configuration. Additionally, when the first front panel  531   a  is folded along the fold line  533   a , the enlarged portion  585   a  of the first front panel  531   a  can at least partially overlap the attachment portion  585   b  of the second front panel  531   b  so that the glue strip G 1 ′ can secure the attachment portion  585   b  and the enlarged portion  585   a  together ( FIG. 15 ). 
     As shown in  FIG. 15 , the partially-formed carton can be folded along the fold lines  525   a ,  525   b ,  533   a ,  533   b ,  137   a ,  137   b ,  141   a ,  141   b  to move the front panels  531   a ,  531   b  away from the back panel  521  and to extend opposite to the back panel  521 . In some embodiments, the carton  501  can be moved from the flattened configuration to the erected configuration ( FIG. 16 ) manually and/or in an automated apparatus (not shown), wherein suction cups mounted on an actuator engage the front panels  531   a ,  531   b  at locations  589  (schematically indicated by circles in  FIGS. 15 and 16 ) and the actuator moves the front panels  531   a ,  531   b  into position opposite the back panel  521  while the back panel  521  is held in place (e.g., by vacuum pressure). In addition or alternatively, the suction cups can hold the front panels in position as the partially-formed carton is conveyed in a machine (e.g., during loading of the articles C into the carton). In one embodiment, the windows  587 ,  591  can provide product visibility while the locations  589  provide sufficient surface area on the front panels  531   a ,  531   b  for the suction cups to engage the carton (e.g., during erection of the carton, loading of the carton, and/or transport of the carton). As shown in  FIG. 16 , the end flaps  527   a ,  527   b ,  528   a ,  528   b  can be folded to overlap one another at the ends of the carton  501  and can be secured (e.g., glued) together to at least partially close the ends of the carton  501 . In addition, as shown in  FIG. 16 , the inner flaps  592  can be folded along the intermediate fold lines  593  and one or more of the lines of perforation  561  so that the distal portions of the inner flaps  592  overlap the back panel  521  and the proximal portions of the inner flaps  592  extend from the back panel  521  to the respective front panels  531   a ,  531   b . In one embodiment, the distal portions of the inner flaps  592  can be secured (e.g., glued by glue dots, glue strips, and/or other suitable features) to the back panel  521 . 
     In the illustrated embodiment, the compartments  503  can be similar to the compartments  103 ,  303  of the prior embodiments. As shown in  FIG. 16 , portions of the respective front panels  531   a ,  531   b , the respective side panels  523   a ,  523   b , and the back panel  521  as well as the respective divider panels  135   a ,  135   b , the respective attachment flaps  539   a ,  539   b , the respective inner flaps  592 , the respective back end flaps  527   b , and the respective front end flaps  528   b  can extend at least partially around the respective interior spaces  573  of the compartments  503 . In the illustrated embodiment, the compartment  505  can be similar to the compartments  105 ,  305  of the prior embodiments, and portions of the back panel  521  and the side panels  523   a ,  523   b  as well as the enlarged portion  585   a  of the first front panel  531   a , the attachment portion  585   b  of the second front panel  531   b , the back end flaps  527   a , and the front end flaps  527   b  can extend at least partially around the interior space  573  of the compartment  505  ( FIG. 16 ). In one embodiment, the proximal portions of the inner flaps  592  can further define the compartment  505  in the interior of the carton  501 . 
     In one embodiment, the articles C, P can be loaded into the compartments  503 ,  505  to form the package  507  ( FIG. 17 ) similarly as described above in relation to the prior embodiments before the end flaps  527   a ,  528   a ,  527   b ,  528   b . As shown in  FIG. 17 , the windows  587 ,  591  can provide visibility of the articles C, P in the interior spaces  573  of the compartments  503 ,  505  in the package  507 . The carton  501  and/or the package  507  could be otherwise formed without departing from the disclosure. 
     As shown in  FIG. 17 , the envelope  601  can be formed from the envelope blank  600  by folding the side attachment flaps  617  over the central panel  611  along the fold lines  619  and folding the cover panel  613  over the central panel  611  and the side attachment flaps  617 . The cover panel  613  can be glued or otherwise secured to the side attachment flaps  617 . As shown in  FIG. 17 , the central panel  611 , the cover panel  613 , and the side attachment flaps  617  can extend around an interior  633  of the envelope  601 , and the package  507  can be inserted into the envelope interior  633  through an opening  635  between the end attachment flap  621  and the top edge of the cover panel  613 . When the package  507  is fully inserted into the envelope interior  633 , the end attachment flap  621  can be folded along the fold line  623  to overlap the cover panel  613 . A distal portion of the end attachment flap  621  (e.g., defined by the tear strip  625 ) can be glued to the cover panel  613  to close the envelope  601  with the package  507  in the envelope interior  633 . The envelope  601  could be otherwise formed and/or the package  507  could be otherwise loaded into the envelope  601  without departing from the disclosure. 
     In one embodiment, the flexibility features  509  of the carton  501  can cooperate with the flexibility features  609  in the envelope  601  (e.g., the score lines  151 ,  590  in the carton  501  can be at least partially aligned with the score line  627  in the envelope  601  and one or both of the score lines  553  and the lines of perforations  561  in the carton  501  can be at least partially aligned with the scores  629 ,  631  in the envelope  601 ). Accordingly, the combination of the package  507  and the envelope  601  can be flexed and/or bent in a similar manner as the package  107  of first embodiment (e.g., for at least partially complying with flexibility standards for United States Postal Service flat-size mailpieces). 
     In the illustrated embodiment, the envelope  601  can be opened by tearing along the tear strip  625  and folding the remaining proximal portion of the end attachment flap  621  to allow the package  507  to be removed from the envelope interior  633  at the opening  635 . The compartments  503 ,  505  can be separated and the articles C, P can be accessed similarly as described above with respect to the prior embodiments. The envelope  601  and/or the package  507  could be otherwise opened without departing from the disclosure. 
     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. 
     Generally, as described herein, liners or bags can be formed from a paper stock material, although various plastic or other liner materials also can be used, and can be lined or coated with a desired material. The constructs, blanks, and/or reinforcing sleeves described herein can be made from a more rigid material such as a clay-coated natural kraft (“CCNK”). Other materials such various card-stock, paper, plastic or other synthetic or natural materials also can be used to form the components of the packages described herein. 
     In general, the blanks of the present disclosure may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above. The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blanks may then be coated with a varnish to protect information printed on the blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections. 
     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. 
     In accordance with the exemplary embodiments, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding there along. 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 or depressed 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. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line. 
     The above embodiments may be described as having one or more panels adhered together by glue during erection of the carton embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place. 
     The foregoing description of the disclosure illustrates and describes various embodiments. As various changes could be made in the above construction without departing from the scope of the disclosure, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Furthermore, the scope of the present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments. Additionally, the disclosure shows and describes only selected embodiments, but various other combinations, modifications, and environments are within the scope of the disclosure as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the disclosure.
