In the illustrated embodiment, the package <NUM> can be formed as shown in <FIG>. In one embodiment, the blank <NUM> can be positioned with the coated and/or printed (e.g., clay-coated side) facing upwardly, and the blank <NUM> can be folded along at least the longitudinal fold lines 133a, 133b, 141a, 141b to overlap the back panel <NUM> and the side panels 123a, 123b with the front panels 131a, 131b and the divider panels 135a, 135b and to position the attachment flaps 139a, 139b between the back panel <NUM> and the respective front panels 131a, 131b as shown in <FIG>. In the illustrated embodiment, glue (e.g., in the form of glue strips G1 shown schematically in <FIG>) can be applied to the attachment flaps 139a, 139b and/or the back panel <NUM> (e.g., prior to folding the blank <NUM>) so that the attachment flaps 139a, 139b are glued to the back panel <NUM> when the attachment flaps 139a, 139b are positioned in face-to-face contact with the back panel <NUM> (<FIG>). As shown in <FIG>, the fold lines 141a, 141b can extend along (e.g., in contact with, adjacent, and/or proximate to) the longitudinal tear lines 171a, 171b when the attachment flaps 139a, 139b are glued to the back panel <NUM>.

As shown in <FIG> and <FIG>, the side panels 123a, 123b, the front panels 131a, 131b, and the divider panels 135a, 135b can be folded along the longitudinal fold lines 125a, 125b, 133a, 133b, 137a, 137b, 141a, 141b to at least partially form the compartments <NUM>, <NUM> with portions of the panels <NUM>, 123a, 123b, 131a, 131b, 135a, 135b and the attachment flaps 139a, 139b extending around respective interior spaces <NUM> of the respective compartments <NUM>, <NUM>. For example, a portion of the first side panel 123a, a section of the first front panel 131a defined by the tear strip 159a, the first divider panel 135a, the first attachment flap 139a, and a section of the back panel <NUM> defined by the lateral tear line <NUM>, the longitudinal tear line 171a, and the fold lines 125a, 129b extend along the interior space <NUM> of one of the compartments <NUM> (e.g., the first interior space of the first compartment). Similarly, a portion of the second side panel 123b, a section of the second front panel 131b defined by the tear strip 159b, the second divider panel 135b, the second attachment flap 139b, and a section of the back panel <NUM> defined by the lateral tear line <NUM>, the longitudinal tear line 171b, and the fold lines 125b, 129b extend along the interior space <NUM> of the other one of the compartments <NUM> (e.g., the second interior space of the second compartment). In the illustrated embodiment, a tear-away section <NUM> of the back panel <NUM> can be defined by the tear lines <NUM>, 171a, 171b, 129b extending between the compartments <NUM>. In addition, portions of the side panels 123a, 123b, sections of the front panels 131a, 131b defined by the respective tear strips 159a, 159b, and a section of the back panel <NUM> defined by the lateral tear line <NUM> and the fold lines 125a, 125b, 129a can extend along the interior space <NUM> of the compartment <NUM> (e.g., the third interior space of the third compartment). The compartments <NUM>, <NUM> could be otherwise formed and/or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

As shown in <FIG> and <FIG>, the articles C, P can be loaded into the interior spaces <NUM> of the respective compartments <NUM>, <NUM>. In the illustrated embodiment, the containers C can be inserted into the interior spaces <NUM> of the respective compartments <NUM>. In one embodiment, the containers C can fit tightly in the compartments <NUM> to help prevent the containers C from unintentionally sliding out of the compartments <NUM> but allowing the containers C to be pushed into or pulled out of the compartments <NUM>. As shown in <FIG>, the entire container C fits in the interior space <NUM> of the compartment <NUM> (e.g., from the opening of the compartment <NUM> adjacent the fold line 129b to the tear strip 159a, 159b); however, in alternative embodiments, portions of the containers C can extend outside the compartment <NUM>. The printed article P can be at least partially inserted into the interior space <NUM> of the compartment <NUM> as shown in <FIG> and <FIG>. In one embodiment, the width of the carton <NUM> can be at least partially determined by the width of the printed article P, and the carton <NUM> could be narrower for a smaller printed article P, which could bring the compartments <NUM> closer together and reduce the size of or eliminate the tear-away section <NUM>. In some embodiments, the width of the carton <NUM> can also be at least partially configured for allowing a suitable amount of bending of the carton <NUM> (e.g., at the flexibility features <NUM>). For example, the spacing of the compartments <NUM> can facilitate bending of the carton <NUM>. The articles C, P could be otherwise loaded into the compartments <NUM>, <NUM> in any suitable order or simultaneously without departing from the disclosure.

As shown in <FIG> and <FIG>, the cover panels 147a, 147b and the end panels 127a, 127b can be folded to form the carton <NUM> (<FIG>).

In one embodiment, glue spots G2 (<FIG> and <FIG>) can be applied to the front panels 131a, 131b (and/or to the second cover panel 147b) to adhere the second cover panel 147b to the front panels 131a, 131b. As shown in <FIG>, the end flaps 143a, 143b can be folded along the lateral fold lines 145a, 145b to partially overlap the end of the compartment <NUM> and the first end panel 127a and the first cover panel 147a can be folded along the lateral fold lines 129a, 149a so that the first end panel 127a at least partially overlaps the end flaps 143a, 143b and the end of the compartment <NUM> and the first cover panel 147a partially overlaps the front panels 131a, 131b and the second cover panel 147b. In one embodiment, a glue strip G3 can be applied to the first cover panel 147a (<FIG>) and/or a glue strip G3' can be applied to the second cover panel 147b (<FIG>) to adhere the cover panels 147a, 147b together when the carton <NUM> is closed (<FIG>). Further, glue spots G4 (<FIG> and <FIG>) can be applied to the front panels 131a, 131b (and/or to the first cover panel 147a) to adhere the first cover panel 147a to the front panels 131a, 131b.

As shown in <FIG>, with the cover panels 147a, 147b overlapped and secured, at least the end panels 127a, 127b can close the ends 181a, 181b of the carton <NUM> and at least the back panel <NUM>, the side panels 123a, 123b, the end panels 127a, 127b, and the cover panels 147a, 147b can extend around an interior <NUM> (<FIG>) of the carton <NUM>. In the illustrated embodiment, the carton <NUM> with the articles C, P contained therein as shown in <FIG> can form the package <NUM>. As shown in <FIG> and in <FIG> and <FIG> (as described in more detail below), the flexibility features <NUM> (including the longitudinal score line <NUM>, the lateral score line <NUM>, the oblique scores <NUM>, and/or portions of the tear strip <NUM>) can be arranged along (e.g., approximately along, generally along, substantially along, etc.) the axes of the carton <NUM> for allowing the package <NUM> to bend according to the United States Postal Service's standards for flat-size mailpieces as described in more detail below. The carton <NUM> and the package <NUM> could be otherwise formed without departing from the disclosure.

As shown in <FIG>, the carton <NUM> can be opened and the compartments <NUM>, <NUM> can be separated to break up the package <NUM> and to allow access to the articles C, P in the compartments <NUM>, <NUM>. For example, as shown in <FIG>, the tear strip <NUM> can be torn away from the first cover panel 147a (e.g., by grasping the start tab <NUM> and pulling the tear strip <NUM> apart from the first cover panel 147a). In one embodiment, at least partially removing the tear strip <NUM> can expose the tear strips 159a, 159b in the front panels 131a, 131b in the interior <NUM> of the carton <NUM>. As shown in <FIG>, the tear strips 159a, 159b can be torn away from the front panels 131a, 131b (e.g. by grasping the start tabs <NUM> and pulling the tear strips 159a, 159b apart from the front panels 131a, 131b). As shown in <FIG>, the carton <NUM> can be torn along the lateral tear line <NUM> in the back panel <NUM> and along portions of the side panels 123a, 123b to at least partially separate the compartment <NUM> from the remainder of the carton <NUM> (e.g., including at least the second cover panel 147b, the compartments <NUM>, and the tear-away section <NUM>). Also as shown in <FIG>, the second cover panel 147b and the second end panel 127b can be separated from the compartments <NUM> and the tear-away section <NUM>, such as by grasping the second cover panel 147b at an edge, pulling the second cover panel 147b upwardly away from the front panels 131a, 131b (e.g., separating the glue spots G2) and tearing the second end panel 127b away from the back panel <NUM> along the tear line 129b. In addition, the tear-away section <NUM> can be removed from the compartments <NUM> by tearing along the tear lines 171a, 171b (<FIG> and <FIG>). As shown in <FIG>, the articles C, P can be removed from the separate compartments <NUM>, <NUM> as desired. The package <NUM> could be otherwise opened and/or the compartments <NUM>, <NUM> 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 <NUM>, <NUM> before and/or during the separation of the compartments <NUM>, <NUM>. Alternatively, the carton <NUM> could be opened and the articles C, P could be removed without separating the compartments <NUM>, <NUM>.

In one embodiment, the package <NUM> 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 <NUM>. <NUM> and/or other standards) and/or other shipping, mailing, storage, etc. standards and/or requirements. For example, as shown in <FIG>, the package <NUM> can bend along at least the longitudinal score <NUM> extending in the back panel <NUM>, the end panels 127a, 127b, and the cover panels 147a, 147b. In one embodiment, the oblique scores <NUM> in the end panels 127a, 127b can help the end panels 127a, 127b deform as the package <NUM> is flexed. Similarly, as shown in <FIG>, the package <NUM> can bend along the axis that is transverse to the longitudinal score <NUM>. For example, the package <NUM> can bend along the lateral score <NUM> extending in the back panel <NUM> and the side panels 123a, 123b and along portions of the tear strip <NUM> in the front panel <NUM>. In one embodiment, the front panels 131a, 131b in the interior <NUM> of the carton <NUM> can also bend along portions of the tear strips 159a, 159b (e.g., along the fold lines <NUM>). In one embodiment, the oblique scores <NUM> in the side panels 123a, 123b can help the side panels 123a, 123b deform as the package <NUM> is flexed. As shown in <FIG>, the back panel <NUM> can bend along the lateral score <NUM> and/or the tear line <NUM> in one embodiment. The package <NUM> could otherwise bend or flex or could be less capable of flexing and/or bending without departing from the disclosure.

In the illustrated embodiment, the end flaps <NUM> can be folded along the fold lines <NUM>, <NUM> and can be glued in face-to-face contact with the respective end panels 327a, 327b (e.g., at glue spots G6). Alternatively, the glue spots G6 could be omitted so that the end flaps <NUM> are not glued to the end panels 327a, 32b. In one embodiment, gluing the end flaps <NUM> to the end panels 327a, 327b can cause the blank <NUM> to fold along the fold lines 329a, 329b so that the end panels 323a, 323b extend over the ends of the carton, the first end panel 329a at least partially closing the ends of the compartments <NUM> and the second end panel 329b at least partially closing the end of the compartment <NUM>. As shown in <FIG>, the side panels 323a, 323b and the end panels 327a, 327b can be folded to extend obliquely (e.g. upwardly and inwardly) from the back panel <NUM>. The second cover panel 347b can be folded along the lateral fold line 349b and can be positioned to overlap the front panels 331a, 331b. In one embodiment, the second cover panel 347b can be glued in face-to-face contact with the front panels 331a, 331b (e.g., at glue spots G7). In one embodiment, the second cover panel 347b can extend along the interior <NUM> and can at least partially close the compartment <NUM>. Subsequently, the first cover panel 347a can be folded along the lateral fold line 349a to at least partially overlap the second cover panel 347b and can be glued in face-to-face contact with the second cover panel 347b (e.g., along glue strip G8). The carton <NUM> and/or the package <NUM> could be otherwise formed without departing from the disclosure.

In one embodiment, the package <NUM> can be flexed and/or bent in a similar manner as the package <NUM> 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>, the package <NUM> can be at least partially opened by tearing the tear strip <NUM> in the first cover panel 347a and pulling the second cover panel 347b upwardly away from the front panels 331a, 331b. Separating the second cover panel 347b from the front panels 331a, 331b can include tearing along the glue spots G7 (<FIG>). In one embodiment, with the carton <NUM> in the open configuration of (<FIG>), the articles C can be removed from the interior spaces <NUM> of the compartments <NUM> and the article P can be removed from the recess <NUM> of the compartment <NUM>. The carton <NUM> could be alternatively opened and/or the articles C, P could be alternatively removed without departing from the disclosure.

<FIG> is a plan view of a blank <NUM> for forming a package <NUM> (<FIG>) including a carton <NUM> (<FIG> and <FIG>) and the articles C, P (<FIG>) or other articles and <FIG> is a plan view of an envelope blank <NUM> for forming an envelope <NUM> (<FIG>) for holding the package <NUM> according to a third embodiment of the disclosure. The third embodiment is generally similar to the prior embodiments, except for variations noted and variations that will be apparent to one of ordinary skill in the art. Accordingly, similar or identical features of the embodiments have been given like or similar reference numbers. As shown in <FIG>, the L3 direction is longer than the L4 direction; however, for the purposes of the third embodiment, the L3 direction will be referred to as the lateral direction L3 of the blank <NUM> and the L4 direction will be referred to as the longitudinal direction L4 of the blank <NUM> so that the names of the features in the blank <NUM> and the carton <NUM> comport with the names of the features in the prior embodiments (e.g., the longitudinal score <NUM> and the lateral tear line <NUM> of the third embodiment comport with the respective longitudinal score <NUM> and lateral tear line <NUM> of the first embodiment). As shown in <FIG>, the blank <NUM> includes a back panel <NUM> that is similar to the back panel <NUM> of the first embodiment except that the flexibility features <NUM> of the third embodiment include two lateral scores <NUM> in the back panel <NUM> rather than the one lateral score <NUM> in the back panel <NUM> of <FIG>. In the illustrated embodiment, the cover panels 147a, 147b are omitted in the blank <NUM> and the back panel <NUM> is foldably connected to two back end flaps 527a, 527b at opposite ends (rather than the end panels 121a, 121b). As shown in <FIG>, the end flaps 527a, 527b at the respective ends of the back panel <NUM> can be spaced apart by a cutout, which can be aligned with the longitudinal score <NUM> of the flexibility features <NUM> and with the longitudinal tear lines 171a, 171b. The back panel <NUM>, the flexibility features <NUM>, and/or the back end flaps 527a, 527b could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

In the illustrated embodiment, the back panel <NUM> is foldably connected to the side panels 523a, 523b along respective longitudinal fold lines 525a, 525b, and front panels 531a, 531b are foldably connected to the respective side panels 523a, 523b along respective fold lines 533a, 533b. As shown in <FIG>, the side panels 523a, 523b and the longitudinal fold lines 525a, 525b, 533a, 533b are interrupted by side openings <NUM> in the blank <NUM>. In the illustrated embodiment, the side openings <NUM> are aligned with the lateral scores <NUM> of the flexibility feature <NUM> and the lateral tear line <NUM> in the back panel <NUM>. As shown in <FIG>, attachment flaps 539a, 539b can be similar to the attachment flaps 139a, 139b of the first embodiment, except that the first attachment flap 539a is larger. The side panels 523a, 523b, the front panels 531a, 531b, the side openings <NUM>, and/or the attachment flaps 539a, 539b could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

In the embodiments shown in <FIG> and <FIG>, the front panels 131a, 131b of the blank <NUM> and the front panels 331a, 331b of the blank <NUM> are symmetric (e.g., the first front panels 131a, 331a are mirror images of the second front panels 131b, 331b). As shown in <FIG>, the portions of the front panels 531a, 531b that form the compartment <NUM> (<FIG>) are different in the blank <NUM>. The first front panel 531a includes an enlarged portion 585a that has a width (in the lateral direction L3) that is similar to or the same as the width (e.g., in the lateral direction L3) of the back panel <NUM> and the second front panel 531b has a smaller attachment portion 585b that is sized to receive a glue strip G1' (<FIG>) for attachment to the enlarged portion 585a of the first front panel 531a. In one embodiment, a window <NUM> can extend in the enlarged portion 585a of the first front panel 531a so that the article P is visible through the first front panel 531a when the carton <NUM> is formed (<FIG> and <FIG>). In an exemplary embodiment, the edge of the window <NUM> in the enlarged portion 585a can have convex curved portions at the corners of the windows to accommodate locations <NUM> (schematically indicated by circles on the blank <NUM>). In one embodiment, the locations <NUM> can provide engagement areas where suction cups (not shown) can engage the first front panel 531a during an automated assembly process (e.g., as described in more detail below. The portions 585a, 585b, the window <NUM>, and/or the locations <NUM> could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

As shown in <FIG>, the enlarged portion 585a can include a front score <NUM>, which is part of the flexibility features <NUM> and is aligned with the longitudinal score <NUM> when the carton <NUM> is formed and the front panel is positioned opposite to the back panel <NUM>. In the illustrated embodiment, two front end flaps 528a can be foldably connected to the enlarged portion of the first end panel 531a along fold lines 530a for cooperating with the end flaps 527a for at least partially closing one end of the carton <NUM>. As shown in <FIG>, the front end flaps 528a are spaced apart from one another by a cutout, which can be aligned with the front score <NUM> of the flexibility features <NUM>. In addition, front end flaps 528b can be foldably connected to the respective front panels 531a, 531b along fold lines 530b opposite to the front end flaps 528a for cooperating with the end flaps 527b to at least partially close the opposite end of the carton <NUM>. The front end flaps 528a, 528b could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

As shown in <FIG>, the front panels 531a, 531b each include a plurality of perforations <NUM> (e.g., three lines of perforations <NUM>, each) that extend in the L3 direction and are at least partially aligned with the openings <NUM>, the lateral scores <NUM>, and the lateral tear line <NUM>. Accordingly, the lines of perforations <NUM> can cooperate with the flexibility features <NUM> for allowing the package <NUM> to flex as described above with respect to the first embodiment. In one embodiment, at least one of the lines of perforations <NUM> can form a tear line in the front panels 531a, 531b for separating the compartments of the package <NUM>. Any of the lines of perforations <NUM> 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 531a, 531b includes a window <NUM> extending in the portion of the front panels 531a, 531b the forms the compartments <NUM> of the carton <NUM> (<FIG>). The windows <NUM> can provide product visibility when the package <NUM> is formed. As shown in <FIG>, the edges of the windows <NUM> can include a respective concave curved portion for forming additional locations <NUM> in the front panels 531a, 531b for being engaged by suction cups (not shown). In the illustrated embodiment, inner flaps <NUM> can be foldably connected to the respective front panels 531a, 531b along the lines of perforations <NUM> and can extend in the respective windows <NUM> in the blank <NUM>. Each of the inner flaps <NUM> can include an intermediate fold line <NUM> (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 <NUM> can be separable from the respective front panels 531a, 531b along cut lines <NUM> and can be held in place by nicks <NUM> until the nicks are broken when forming the carton <NUM>. The windows <NUM> and/or the inner flaps <NUM> could be omitted or could be otherwise arranged, shaped, positioned, and/or configured without departing from the disclosure.

As shown in <FIG>, the envelope blank <NUM> has a lateral axis L5 and a longitudinal axis L6. In the illustrated embodiment, the envelope blank <NUM> has a central panel <NUM> foldably connected to a cover panel <NUM> along a lateral fold line <NUM>. In one embodiment, two side attachment flaps <NUM> are foldably connected to the central panel <NUM> along respective longitudinal fold lines <NUM> on opposing sides of the central panel <NUM>. As shown in <FIG>, an end attachment flap <NUM> can be foldably connected to the central panel <NUM> along a lateral fold line <NUM> at an opposite end of the central panel <NUM> from the cover panel <NUM>. In an exemplary embodiment, the end attachment flap <NUM> can include a tear strip <NUM> for facilitating opening the envelope <NUM> formed from the envelope blank <NUM>. As shown in <FIG>, the envelope blank <NUM> can include flexibility features <NUM> similar to the flexibility features <NUM> for cooperating with the flexibility features <NUM>. In the illustrated embodiment, the flexibility features <NUM> can include a longitudinal score <NUM> extending in the central panel <NUM>, the cover panel <NUM>, and the end attachment flap <NUM> (e.g., along a longitudinal axis of the envelope blank <NUM>). The flexibility features <NUM> further can include a lateral score <NUM> extending in the central panel <NUM> and each of the side attachment flaps <NUM> and a lateral score <NUM> extending in the cover panel <NUM>. The envelope blank <NUM> 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 <NUM> can be formed similarly to the cartons of the prior embodiments. For example, glue strips G1 can be applied to the exterior surfaces of the attachment flaps 539a, 539b and the glue strip G1' can be applied to the exterior surface of the attachment portion 585b of the second front panel 531b. In one embodiment, the first attachment flap 539a can be folded over the first divider panel 135a along the fold line 141a and the second attachment flap 539b and the second divider panel 135b can be folded over the second front panel 531b along the fold lines 137b. Subsequently, the second front panel 531b and the second side panel 523b can be folded over the back panel <NUM> along the fold line 525b and the first front panel 531a can be folded over the first side panel 523a and the back panel <NUM> along the fold line 533a. As the front panels 531a, 531b are folded, the attachment flaps 539a, 539b extend between the front panels 531a, 531b and the back panel <NUM> and so that the glue strips G1 secure the attachment flap 539a, 539b to the back panel <NUM> (<FIG>) when the panels are folded and the partially-formed carton is in a flattened configuration. Additionally, when the first front panel 531a is folded along the fold line 533a, the enlarged portion 585a of the first front panel 531a can at least partially overlap the attachment portion 585b of the second front panel 531b so that the glue strip G1' can secure the attachment portion 585b and the enlarged portion 585a together (<FIG>).

As shown in <FIG>, the partially-formed carton can be folded along the fold lines 525a, 525b, 533a, 533b, 137a, 137b, 141a, 141b to move the front panels 531a, 531b away from the back panel <NUM> and to extend opposite to the back panel <NUM>. In some embodiments, the carton <NUM> can be moved from the flattened configuration to the erected configuration (<FIG>) manually and/or in an automated apparatus (not shown), wherein suction cups mounted on an actuator engage the front panels 531a, 531b at locations <NUM> (schematically indicated by circles in <FIG> and <FIG>) and the actuator moves the front panels 531a, 531b into position opposite the back panel <NUM> while the back panel <NUM> 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 <NUM>, <NUM> can provide product visibility while the locations <NUM> provide sufficient surface area on the front panels 531a, 531b 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>, the end flaps 527a, 527b, 528a, 528b can be folded to overlap one another at the ends of the carton <NUM> and can be secured (e.g., glued) together to at least partially close the ends of the carton <NUM>. In addition, as shown in <FIG>, the inner flaps <NUM> can be folded along the intermediate fold lines <NUM> and one or more of the lines of perforation <NUM> so that the distal portions of the inner flaps <NUM> overlap the back panel <NUM> and the proximal portions of the inner flaps <NUM> extend from the back panel <NUM> to the respective front panels 531a, 531b. In one embodiment, the distal portions of the inner flaps <NUM> can be secured (e.g., glued by glue dots, glue strips, and/or other suitable features) to the back panel <NUM>.

In the illustrated embodiment, the compartments <NUM> can be similar to the compartments <NUM>, <NUM> of the prior embodiments. As shown in <FIG>, portions of the respective front panels 531a, 531b, the respective side panels 523a, 523b, and the back panel <NUM> as well as the respective divider panels 135a, 135b, the respective attachment flaps 539a, 539b, the respective inner flaps <NUM>, the respective back end flaps 527b, and the respective front end flaps 528b can extend at least partially around the respective interior spaces <NUM> of the compartments <NUM>. In the illustrated embodiment, the compartment <NUM> can be similar to the compartments <NUM>, <NUM> of the prior embodiments, and portions of the back panel <NUM> and the side panels 523a, 523b as well as the enlarged portion 585a of the first front panel 531a, the attachment portion 585b of the second front panel 531b, the back end flaps 527a, and the front end flaps 527b can extend at least partially around the interior space <NUM> of the compartment <NUM> (<FIG>). In one embodiment, the proximal portions of the inner flaps <NUM> can further define the compartment <NUM> in the interior of the carton <NUM>.

In one embodiment, the articles C, P can be loaded into the compartments <NUM>, <NUM> to form the package <NUM> (<FIG>) similarly as described above in relation to the prior embodiments before the end flaps 527a, 528a, 527b, 528b. As shown in <FIG>, the windows <NUM>, <NUM> can provide visibility of the articles C, P in the interior spaces <NUM> of the compartments <NUM>, <NUM> in the package <NUM>. The carton <NUM> and/or the package <NUM> could be otherwise formed without departing from the disclosure.

As shown in <FIG>, the envelope <NUM> can be formed from the envelope blank <NUM> by folding the side attachment flaps <NUM> over the central panel <NUM> along the fold lines <NUM> and folding the cover panel <NUM> over the central panel <NUM> and the side attachment flaps <NUM>. The cover panel <NUM> can be glued or otherwise secured to the side attachment flaps <NUM>. As shown in <FIG>, the central panel <NUM>, the cover panel <NUM>, and the side attachment flaps <NUM> can extend around an interior <NUM> of the envelope <NUM>, and the package <NUM> can be inserted into the envelope interior <NUM> through an opening <NUM> between the end attachment flap <NUM> and the top edge of the cover panel <NUM>. When the package <NUM> is fully inserted into the envelope interior <NUM>, the end attachment flap <NUM> can be folded along the fold line <NUM> to overlap the cover panel <NUM>. A distal portion of the end attachment flap <NUM> (e.g., defined by the tear strip <NUM>) can be glued to the cover panel <NUM> to close the envelope <NUM> with the package <NUM> in the envelope interior <NUM>. The envelope <NUM> could be otherwise formed and/or the package <NUM> could be otherwise loaded into the envelope <NUM> without departing from the disclosure.

In one embodiment, the flexibility features <NUM> of the carton <NUM> can cooperate with the flexibility features <NUM> in the envelope <NUM> (e.g., the score lines <NUM>, <NUM> in the carton <NUM> can be at least partially aligned with the score line <NUM> in the envelope <NUM> and one or both of the score lines <NUM> and the lines of perforations <NUM> in the carton <NUM> can be at least partially aligned with the scores <NUM>, <NUM> in the envelope <NUM>). Accordingly, the combination of the package <NUM> and the envelope <NUM> can be flexed and/or bent in a similar manner as the package <NUM> 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 <NUM> can be opened by tearing along the tear strip <NUM> and folding the remaining proximal portion of the end attachment flap <NUM> to allow the package <NUM> to be removed from the envelope interior <NUM> at the opening <NUM>. The compartments <NUM>, <NUM> can be separated and the articles C, P can be accessed similarly as described above with respect to the prior embodiments. The envelope <NUM> and/or the package <NUM> 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.
