## Background
CROSS-REFERENCE TO RELATED APPLICATION
This nonprovisional application claims priority to U.S. Provisional Patent Application Ser. No. 61/988,531, filed on May 5, 2014, which is hereby incorporated by reference in its entirety.


FIELD
The field of this disclosure relates generally to packs used to facilitate carrying a load by a user and, more particularly, to a pack having a one-piece, seamless bodyside liner to facilitate user comfort.
BACKGROUND
Conventional backpacks typically include a plurality of panels stitched together to cooperatively define an interior compartment adapted to store objects for transport in the backpack and include a pair of shoulder straps attached to one or more of the panels for carrying the backpack on a user's back. The interior compartment is often selectively accessible by moving a suitable fastening system comprising one or more suitable fasteners (e.g., a slide fastener, straps, hook and loop, snaps, buttons) between a closed position and an opened position. In addition to the interior compartment, known backpacks may also have interior and/or exterior pockets for holding additional objects for transport in the backpack. In some configurations, these pockets are selectively moveable between closed and opened positions using any suitable fastening system. In other configurations, the pockets are open and thus, not selectively closeable.
Known backpacks often have a liner or other suitable material that covers the portion of the backpack adapted to face the user during use. More specifically, the bodyfacing surface of the shoulder straps and the bodyfacing surface of one or more of the panels may include a liner adapted for placement against the user during use of the backpack. However, known liners comprise a number of segments (e.g., not a single-piece) and are stitched (i.e., not seamless) to the underlying structure. During use, the edges of these liner segments and the stitching can irritate the skin of the user. For example, if a runner is using such a backpack and wearing a relatively light weight shirt or no shirt, the edges of the liner segments and/or the stitching can rub against the skin of the user while he/she is running causing chaffing, abrasion, a rash, or other skin irritation.
In view of the above drawbacks, there remains a need for a backpack having a liner that inhibits skin irritation, such as chaffing, abrasion or rash, during use of the backpack while providing comfort, durability, moisture resistance, stain resistance, and odor resistance.

With reference now to the drawings, FIGS. 1-5 illustrate one suitable embodiment of a pack of the present invention in the form of a backpack, indicated generally at 10. The backpack 10 includes a back panel 12, a top panel 14, a bottom panel 16, two side panels (for example, a right side panel 18 and a left side panel 20), and a front panel 22. The panels 16, 18, 20, and 22 cooperatively define at least one interior compartment (not shown) adapted to store objects (not shown) for transport in the backpack 10. In the illustrated embodiment, the interior compartment can be accessed by moving the top panel 14 from a closed position (FIGS. 1-5) to an opened position (not shown). The top panel 14 can be secured in the closed position using any suitable fastening system comprising one or more suitable fasteners (for example, buckles 28) as seen in FIGS. 1 and 2. It is understood that the any suitable fasteners (for example, a slide fastener, straps, hook and loop, snaps, buttons) can be used to secure the top panel 14 in the closed position. It is also understood that the interior compartment can be accessed in a different matter (for example, using a slide fastener to separate one or more of the panels 16, 18, 20, and 22) without departing from some aspects of this disclosure.
As seen in FIGS. 1-3, each of the side panels 18, 20 include a side pocket 30, 32 for receiving objects (not shown). It is contemplated that the backpack 10 can have more or fewer pockets than illustrated herein. It is also contemplated the pockets 30, 32 of the backpack 10 can be secured or fastened using any suitable fastener, such as, elastomeric bands, slide fasteners, hook and loop, straps, buckles, buttons, and snaps. It is further contemplated that the backpack 10 can include pockets on other panels (for example, the front panel 22).
In one suitable embodiment, the panels 12, 14, 16, 18, 20, and 22 are connected to each other by stitching and are formed from a sufficiently durable and compliant material. The material of the panels 12, 14, 16, 18, 20, and 22 can be any suitable material, including but not limited to, nylon and polyester. Suitably, the material of the panels 16, 18, 20, and 22 is relatively soft, durable, water resistant, odor resistant, and stain resistant.
With reference to FIG. 2, the back panel 12 of the backpack 10 includes a pair of shoulder straps 34 for carrying the backpack 10 on a user's back (not shown). It is contemplated that in other suitable embodiments the backpack 10 can be provided with a single shoulder strap 34 (for example, a sling bag, and a messenger bag). The backpack 10 also includes a handle strap 36 disposed between the back panel 12 and the top panel 14 for manually carrying the backpack 10 with a single hand or for hanging the backpack 10 (for example, on a suitable hook).
In the illustrated embodiment, each of the shoulder straps 34 includes a plurality of pockets 38 for receiving objects (not shown). More specifically, the illustrated backpack 10 has two pockets 44 on each of the shoulder straps 34 but it is understood that the shoulder straps 34 can have any suitable number of pockets or, in other suitable embodiments, be free of pockets. It is also contemplated that the pockets 38 of the shoulder straps 34 can be secured or fastened using any suitable fastener, such as, elastomeric bands, slide fasteners, hook and loop, straps, buckles, buttons, and snaps. As seen in FIG. 2, for example, one of the pockets 38 is selectively closeable using a slide fastener (or zipper) and another using hook and loop.
It is contemplated that the backpack 10 can have any suitable size and shape without departing from some aspects of this invention. In one suitable embodiment, the backpack 10 is configured for allowing the user significant movement (for example, running, jogging, hiking, biking, skiing, climbing) while wearing the backpack 10. In such an embodiment, the backpack 10 is suitably light weight. For example, in one suitable embodiment, the backpack 10 is less than two pounds, more preferably less than one pound, eight ounces, and even more preferably less than one pound.
In one suitable embodiment, the backpack 10 can be configured to receive any suitable hydration container (not shown). For example, the backpack 10 can have one or more exterior water bottle pocket for receive a water bottle (for example, a 20 ounce or 26 ounce bottle with kicker valve available from Ultimate Direction of Boulder, Colo., U.S.A.) and/or an interior reservoir pocket for receiving a reservoir (for example, a 70 ounce or 100 ounce reservoir also available from Ultimate Direction of Boulder, Colo. U.S.A.).
With reference now to FIGS. 2 and 6, the backpack 10 further includes a one-piece, seamless bodyside liner, indicated generally at 40, that lines (or covers) the back panel 12 and/or both of the shoulder straps 34 of the backpack 10. Thus, during use, the seamless bodyside liner 40 is configured for direct face-to-face engagement with the user. Since the bodyside liner 40 is a single-piece of material and does not include any seams, the bodyside liner 40 is less likely to cause skin irritation (such as, but not limited to, chaffing, rashes, and abrasions). More particularly, the seamless bodyside liner 40 of the backpack 10 illustrated and described herein inhibits skin irritation during use of the backpack 10 especially high activity use involving significant movement by the user (for example, running, jogging, hiking, biking, skiing, climbing).
Referring to FIG. 6, the bodyside liner 40 is shown in a laid flat configuration. The bodyside liner 40 includes a body portion 42 for lining the back panel 12 of the backpack 10 and two strap portions 44 for lining each of the shoulder straps 34. As mentioned above, the bodyside liner 40 is a single-piece of material. Thus, the two strap portions 44 of the bodyside liner 40 are integral with the body portion 42. Alternatively, the body portion 42 and the two strap portions 44 may be separately attachable to the bodyside liner 40 and/or the backpack 10. The bodyside liner 40 further includes a peripheral edge 46.
The bodyside liner 40 can be made from any suitable material. Preferably, the bodyside liner 40 is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner 40 comprises a suitable mesh material 45 but it is understood that the bodyside liner 40 can include any suitable material without departing from some aspects of this disclosure. For example, one suitable mesh material is available from Duck San Co., LTD of Gyeonggido, South Korea under product number DS14-42.
In the illustrated embodiment, the bodyside liner 40 is attached (for example, by stitching) to the back panel 12 and shoulder straps 34 only along or adjacent the peripheral edge 46. That is, the portions of the bodyside liner 40 inboard of the peripheral edge 46 are free from attachment to the underlying structure (for example, the back panel 12 and shoulder straps 34). As a result, the bodyside liner 40 is free from inboard seams and the only seam associated with the bodyside liner 40 is a peripheral seam attaching the bodyside liner 40 to the underlying structure, for example, the back panel 12 and/or the shoulder straps 34.
In one suitable embodiment, an edge binding 47 is disposed about at least about a portion of the peripheral edge 46 of the bodyside liner 40. In the illustrated embodiment, for example, the edge binding 47 is disposed about the periphery of the strap portions 44 of the bodyside liner 40. As a result, the edge binding 47 trims the attachment of the bodyside liner 40 to the shoulder straps 34. Moreover, the edge binding 47 is disposed about a portion of the body portion 42 of the bodyside liner 40. More particularly, only part of the attachment between the bodyside liner 40 and the back panel 12 is trimmed by the edge binding 47. It is understood, however, edge binding 47 can be used to trim more (including entirely) or less of the peripheral edge 46 of the bodyside liner 40. It is further understood that in some suitable embodiments, the edge binding 47 can be omitted. In such an embodiment, the bodyside liner 40 can have a self-bound seam about the peripheral edge 46.
It is contemplated that the bodyside liner 40 can be attached to the back panel 12 and/or shoulder straps 34 (or other portion(s) of the backpack 10) using any suitable method. That is, the bodyside liner 40 can be attached to the back panel 12 and/or shoulder straps 34 by any means known in the industry that utilizes a suitable mechanical attachment, such as, but not limited to, sewing, bonding, and coupling between two or more fabric layers to permanently bind them together. It is also contemplated that the entire bodyfacing surface of the bodyside liner 40 including along or adjacent the peripheral edge 46 can be seam free. Thus, the portions of the bodyside liner 40 facing the wearer (for example, the bodyfacing surface(s) of the liner 40) can be free from attachment to the underlying structure, such as the back panel 12 and shoulder straps 34. For example, the bodyside liner 40 can be attached to the back panel 12 and/or shoulder straps 34 beyond the bodyfacing surface(s) of the bodyside liner 40 using, for example only, a sew-and-turn (or stitch-and-flip) technique as is known in the industry.
With reference still to FIG. 6, the illustrated embodiment of the backpack 10 further comprises an insert layer 48 underlying at least a portion of the bodyside liner 40. The insert layer 48 is disposed between at least a portion of the bodyside liner 40 and the back panel 12 and/or the shoulder straps 34. As seen in FIG. 6, the illustrated insert layer 48 comprises a body portion 50 and a pair of strap portions 52 separate from the body portion 50. Alternatively, the pair of strap portions 52 can be integrated with the body portion 50. The body portion 50 of the insert layer 48 underlies the body portion 42 of the bodyside liner 40, and the strap portions 52 of the insert layer underlie the strap portions 44 of the bodyside liner 40. It is contemplated that the insert layer 48 can be formed from a single-piece of material or a plurality of separate, discrete pieces. The insert layer 48 facilitates attaching the bodyside liner 40 to the backpack 10.
Moreover, the insert layer 48 can be formed from any suitable material or combination of suitable materials. Preferably, the insert layer 48 is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, at least a portion of the insert layer 48 comprises a suitable mesh material. In the illustrated embodiment, for example, the entire insert liner 48 is formed by the mesh material. In another suitable embodiment, at least a portion of the insert layer 48 comprises a suitable padding material (for example, ethylene vinyl acetate (or EVA) padding). In an embodiment, the body portion 42 of the bodyside liner 40 comprises a suitable mesh material, and the strap portions 52 of the insert layer 48 comprise a suitable padding material. In other suitable embodiments, the insert layer 48 can be, in whole or in part, any suitable foam, sponge, or other padding material including but not limited to EVA, PU, PE, designed to provide structure, support, pressure distribution and/or cushioning at the interface between the backpack 10 and the wearer. In another suitable embodiment, the insert layer 48 can be any fabric, flexible molded plastic or composite, or other manufactured structure which is able to conform on a majority but limited basis to the wearer's body in such manner that areas where the insert layer 48 does not conform such non-conforming portion is designed to enhance breathability and air flow between the user and the backpack 10. It is also contemplated that is other suitable embodiments, the insert layer 48 can be eliminated or have any suitable configuration without departing from some aspects of this disclosure.
As shown in FIG. 7, it is contemplated that the backpack 10 illustrated in FIGS. 1-6 can include a waistbelt 53 for releasably securing the backpack 10 around the user's waist. In one suitable embodiment, the waistbelt 53 is selectively adjustable such that the backpack 10 can be form fitted to the user's waist when the backpack 10 is worn. In one embodiment of the backpack 10 having a waist belt 53, the bodyside liner 40 can be configured to cover the body-facing portions of the waist belt 53. Thus, in such an embodiment, the one-piece seamless bodyside liner 40 lines (or covers) the back panel 12, both of the shoulder straps 34, and the waist belt 53.
FIGS. 8 and 9 illustrate another suitable embodiment of a one-piece, seamless bodyside liner, indicated generally at 54 that is suitable for use with the backpack 10 seen in FIGS. 1-5. FIG. 8 illustrates the bodyside liner 54 in laid flat condition and FIG. 9 illustrates the bodyside liner 54 is a folded (or use) condition. The bodyside liner 54 is configured to line (or cover) the back panel 12 and/or both of the shoulder straps 34 of the backpack 10. Thus, during use, the seamless bodyside liner 54 is configured for direct face-to-face engagement with the user. Since the bodyside liner 54 is a single-piece of material and does not include any seams, the bodyside liner 54 is less likely to cause skin irritation (for example, chaffing, rashes, and abrasions) during use of the backpack 10.
As seen in FIGS. 8 and 9, the bodyside liner 54 includes a body portion 56 for lining the back panel 12 of the backpack 10 and two strap portions 58 for lining each of the shoulder straps 34. As mentioned above, the bodyside liner 54 is a single-piece of material. Thus, the two strap portions 58 of the bodyside liner 54 are integral with the body portion 56. Alternatively, the body portion 56 and the two strap portions 58 may be separately attachable to the bodyside liner 54 and/or the backpack 10.
The bodyside liner 54 can be made from any suitable material. Preferably, the bodyside liner 54 is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner 54 includes a suitable mesh material 60 but it is understood that the bodyside liner 54 can include any suitable material without departing from some aspects of this disclosure. In this embodiment, the mesh material 60 includes a plurality of first areas 62 of mesh having a first weave configuration 64, and a plurality of second areas 66 of mesh having a second weave configuration 68 that is different than the first weave configuration 64. In the illustrated embodiment, the first areas 62 having the first weave configuration 64 includes a tight weave; and, the second areas 66 having the second weave configuration 68 includes a medium weave. Alternatively, the first weave configuration 64 may include a medium weave or a low/loose weave. Moreover, the second weave configuration 68 may include a tight weave or a low/loose weave. It is understood that the first and second areas 62, 66 of the bodyside liner 54 can have other characteristics that are different instead of or in addition to the weave. The first areas 62 and second areas 66 are configured to facilitate providing characteristics such as, but not limited to, comfort, durability, moisture resistance, odor resistance, and stein resistance for the bodyside liner 54.
In the exemplary embodiment, the first areas 62 and the second areas 66 are configured in a sequential pattern 69 along the bodyside liner 54. In an embodiment, the first areas 62 and the second areas 66 are configured in an alternating pattern with respect to each other. In one embodiment, the first areas 62 include a Y-shape applied to the body portion 56. Alternatively, the first areas 62 and the second areas 66 can include any pattern. Moreover, the first areas 62 and the second areas 66 are configured to include a plurality of variety of shapes and sizes.
In the exemplary embodiment, the bodyside liner 54 may include the peripheral edge 46 and/or the edge binding 47 (shown in FIG. 6). The bodyside liner 54 can be attached to the back panel 12 and/or shoulder straps 34 (or other portions of the backpack 10) using any suitable method. Moreover, the insert layer 48 (shown in FIG. 6) may be used with the bodyside liner 54.
FIGS. 10-15 illustrate another suitable embodiment of a backpack, indicated generally at 70, of the present disclosure. The backpack 70 includes a back panel 72, a top panel 74, a bottom panel 76, two side panels (for example, a right side panel 78 and a left side panel 80 as viewed in FIG. 10), and a front panel 82. The panels 70, 72, 74, 76, 78, 80, and 82 cooperatively define at least one interior compartment (not shown) adapted to store objects for transport in the backpack 70. In the illustrated embodiment, the interior compartment can be accessed by moving the top panel 74 from a closed position (FIGS. 10-15) to an opened position (not shown). The top panel 74 can be secured in the closed position using any suitable fastening system comprising one or more suitable fasteners. It is understood that the any suitable fasteners (for example, buckles, a slide fastener, straps, hook and loop, snaps, buttons) can be used to secure the top panel 74 in the closed position. It is also understood that the interior compartment can be accessed in a different matter (for example, using a slide fastener to separate one or more of the panels 70, 72, 74, 76, 78, 80, and 82) without departing from some aspects of this disclosure.
As seen in FIGS. 11 and 13, each of the side panels 78, 80 include a side pocket 86, 88 for receiving objects (not shown). It is contemplated that the backpack 70 can have more or fewer pockets than illustrated herein. It is also contemplated the pockets 86, 88 of the backpack 70 can be secured or fastened using any suitable fastener, such as, elastomeric bands, slide fasteners, hook and loop, straps, buckles, buttons, and snaps. It is further contemplated that the backpack 70 can include pockets on other panels (for example, the front panel 82).
In one suitable embodiment, the panels 70, 72, 74, 76, 78, 80, and 82 are connected to each other by stitching and are formed from a sufficiently durable and compliant material. The material of the panels 70, 72, 74, 76, 78, 80, and 82 can be any suitable material, including but not limited to, nylon and polyester. The illustrated panels 70, 72, 74, 76, 78, 80, and 82, for example, are made of nylon. Suitably, the material of the panels 70, 72, 74, 76, 78, 80, and 82 is relatively soft, durable, water resistant, odor resistant, and stain resistant.
With reference to FIG. 14, the back panel 72 of the backpack 70 includes a pair of shoulder straps 90 for carrying the backpack 70 on a user's back. It is contemplated that in other suitable embodiments the backpack 70 can be provided with a single shoulder strap 90 (for example, a sling bag). In the illustrated embodiment, each of the shoulder straps 90 includes a plurality of pockets 92 for receiving objects (not shown). More specifically, the illustrated backpack 70 has two pockets 92 on each of the shoulder straps 90 but it is understood that the shoulder straps 90 can have any suitable number of pockets or, in other suitable embodiments, be free of pockets. It is also contemplated the pockets 92 of the shoulder straps 90 can be secured or fastened using any suitable fastener, such as, elastomeric bands, slide fasteners, hook and loop, straps, buckles, buttons, and snaps. As seen in FIG. 14, for example, one of the pockets 92 is selectively closeable using a slide fastener (or zipper) and another using hook and loop.
It is contemplated that the backpack 70 can have any suitable size and shape without departing from some aspects of this invention. In one suitable embodiment, the backpack 70 is configured for allowing the user significant movement (e.g., running, jogging, hiking, biking, skiing) while wearing the backpack 70. In such an embodiment, the backpack 70 is suitably light weight. For example, in one suitable embodiment, the backpack 70 is less than two pounds, more preferably less than one pound, eight ounces, and even more preferably less than one pound.
In one suitable embodiment, the backpack 70 can be configured to receive any suitable hydration container (not shown). For example, the backpack can have one or more exterior water bottle pocket for receive a water bottle (for example, a 20 ounce or 26 ounce bottle with kicker valve available from Ultimate Direction of Boulder, Colo., U.S.A.) and/or an interior reservoir pocket for receiving a reservoir (e.g., a 70 ounce or 100 ounce reservoir also available from Ultimate Direction of Boulder, Colo. U.S.A.).
With reference now to FIGS. 14 and 15, the backpack 70 further includes a one-piece, seamless bodyside liner, indicated generally at 94, that lines (or covers) the back panel 72 and/or both of the shoulder straps 90 of the backpack 70. Thus, during use, the seamless bodyside liner 94 is configured for direct face-to-face engagement with the user. Since the bodyside liner 94 is a single-piece of material and does not include any seams, the bodyside liner 94 is less likely to cause skin irritation (for example, chaffing, rashes, and abrasions). In other words, the backpack 70 illustrated and described herein inhibits skin irritation during use of the backpack 70 especially high activity use involving significant movement by the user (e.g., running, jogging, hiking, biking, skiing).
The bodyside liner 94 includes a body portion 96 for lining the back panel 72 of the backpack 70 and two strap portions 98 for lining each of the shoulder straps 90. As mentioned above, the bodyside liner 94 is a single-piece of material. Thus, the two strap portions 98 of the bodyside liner 94 are integral with the body portion 96. Alternatively, the body portion 96 and the strap portions 98 may be separately attachable to the bodyside liner 94 and/or the backpack 70. The bodyside liner 94 further includes a peripheral edge 100.
The bodyside liner 94 can be made from any suitable material. Preferably, the bodyside liner 94 is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner 94 comprises a suitable mesh material 101 but it is understood that the bodyside liner 94 can comprise any suitable material without departing from some aspects of this disclosure. For example, one suitable mesh material 101 is available from Duck San Co., LTD of Gyeonggido, South Korea under product number DS14-42.
In the illustrated embodiment, the bodyside liner 94 is attached (for example, by stitching) to the back panel 72 and shoulder straps 90 only along or adjacent the peripheral edge 100 (FIGS. 14 and 15). That is, the portions of the bodyside liner 94 inboard of the peripheral edge 100 are free from attachment to the underlying structure (for example, the back panel 72 and shoulder straps 90). As a result, the bodyside liner 94 is free from inboard seams and the only seam associated with the bodyside liner 94 is the peripheral seam attaching it to the underlying structure, for example the back panel 72 and/or the shoulder straps 90.
In one suitable embodiment, an edge binding 102 is disposed about at least about a portion of the peripheral edge 100 of the bodyside liner 94. In the illustrated embodiment, for example, the edge binding 102 is disposed about the periphery of the strap portions 98 of the bodyside liner 94. As a result, the edge binding 102 trims the attachment of the bodyside liner 94 to the shoulder straps 90. Moreover, the edge binding 102 is disposed about a portion of the body portion 96 of the bodyside liner 94. More particularly, only part of the attachment between the bodyside liner 94 and the back panel 72 is trimmed by the edge binding 102. It is understood, however, edge binding 102 can be used to trim more (including entirely) or less of the periphery of the bodyside liner 94. It is further understood that in some suitable embodiments, the edge binding 102 can be omitted. In such an embodiment, the bodyside liner 94 can have a self-bound seam about the peripheral edge 100. In an embodiment, the insert layer 48 (shown in FIG. 6) may be used with the bodyside liner 94.
FIGS. 16-18 illustrate another suitable embodiment of a one-piece, seamless bodyside liner, indicated generally at 104 that is suitable for use with the backpack 70 seen in FIGS. 10-15. Alternatively, the bodyside liner 104 may be suitable for any type of backpack such as, for example, only, backpack 10 (shown in FIGS. 1-6). The bodyside liner 104 is configured to line (or cover) the back panel 72 and/or both of the shoulder straps 90 of the backpack 70. Thus, during use, the seamless bodyside liner 104 is configured for direct face-to-face engagement with the user. Since the bodyside liner 104 is a single-piece of material and does not include any seams, the bodyside liner is less likely to cause skin irritation (for example, chaffing, rashes, and abrasions) during use of the backpack 70.
As seen in FIGS. 16-18, the bodyside liner 104 includes a body portion 106 for lining the back panel 72 of the backpack 70 and two strap portions 108 for lining each of the shoulder straps 90. As mentioned above, the bodyside liner 94 is a single-piece of material. Thus, the two strap portions 108 of the bodyside liner 104 are integral with the body portion 106. Alternatively, the body portion 106 and the strap portions 108 may be separately attachable to the bodyside liner 104 and/or the backpack 70.
The bodyside liner 104 can be made from any suitable material. Preferably, the bodyside liner 104 is relatively soft, durable, moisture resistant, stain resistant, and odor resistant. In one suitable embodiment, the bodyside liner 104 comprises a suitable mesh material 109 but it is understood that the bodyside liner 104 can comprise any suitable material without departing from some aspects of this disclosure. In this embodiment, the mesh material 109 comprises a plurality of first areas 110 of mesh having a first weave configuration 112, and a plurality of second areas 358 of mesh having a second weave configuration 116 that is different than the first weave configuration 112. In the illustrated embodiment, the first areas 110 having the first weave configuration 112 includes a tight weave and the second areas 114 having the second weave configuration 116 includes a medium weave. Alternatively, the first weave configuration 112 may include a medium weave or a low/loose weave. Moreover, the second weave configuration 116 may include a tight weave or a low/loose weave. It is understood that the first and second areas 110, 114 of the bodyside liner 104 can have other characteristics that are different instead of or in addition to the weave. The first areas 110 and the second areas 114 are configured to facilitate providing characteristics such as, but not limited to, comfort, durability, moisture resistance, odor resistance, and stain resistance for the bodyside liner 104.
In the exemplary embodiment, the first areas 110 and the second areas 114 are configured in a sequential pattern 118 along the bodyside liner. In an embodiment, the first areas 110 and the second areas 114 are configured in an alternating pattern with respect to each other. Moreover, the first areas 110 and the second areas 114 are configured to include a plurality of variety of shapes and sizes. In one embodiment, the first areas 355 include a Y-shape applied to the body portion 106.
In the illustrated embodiment, the bodyside liner 104 is attached (for example, by stitching) to the back panel 72 and shoulder straps 90 only along or adjacent a peripheral edge 120. That is, the portions of the bodyside liner 104 inboard of the peripheral edge 120 are free from attachment to the underlying structure (for example, the back panel 72 and shoulder straps 90). As a result, the bodyside liner 104 is free from inboard seams and the only seam associated with the bodyside liner 104 is the peripheral seam attaching it to the underlying structure, for example the back panel 72 and/or the shoulder straps 90.
In one suitable embodiment, an edge binding 122 is disposed about at least about a portion of the peripheral edge 120 of the bodyside liner 104. In the illustrated embodiment, for example, the edge binding 122 is disposed about the periphery of the strap portions 108 of the bodyside liner 104. As a result, the edge binding 122 trims the attachment of the bodyside liner 104 to the shoulder straps 90. Moreover, the edge binding 122 is disposed about a portion of the body portion 106 of the bodyside liner 104. More particularly, only part of the attachment between the bodyside liner 104 and the back panel 72 is trimmed by the edge binding 122. It is understood, however, edge binding 122 can be used to trim more (including entirely) or less of the periphery of the bodyside liner 104. It is further understood that in some suitable embodiments, the edge binding 122 can be omitted. In such an embodiment, the bodyside liner 104 can have a self-bound seam about the peripheral edge 120. Moreover, the insert layer 48 (shown in FIG. 6) may be used with the bodyside liner 104.
It is contemplated that the one-piece seamless bodyside liners 40, 54, 94, and 104 disclosed herein can be adapted for packs other than backpacks without departing from some aspects of this disclosure. For example, the one-piece seamless bodyside liners 0, 54, 94, and 104 can be adapted for hip packs, waist packs, fanny packs wherein the bodyside liner fully covers the body-facing portions of the respective pack.
