[0013] The following descriptions of various examples and components of this disclosure refer to the accompanying drawings, which form part of them and are shown as various exemplary structures and environments in which aspects of this disclosure can be implemented. It should be understood that other structures and environments may be used, and structural and functional modifications may be made from the structures and methods specifically described without departing from the scope of this disclosure.

[0014] Furthermore, terms such as “front,” “front side,” “rear side,” “back side,” “top,” “base,” “bottom,” “side,” “opposite side,” “front,” and “rear” may be used herein to describe various exemplary features and elements, and these terms are used herein for convenience, for example, based on the exemplary orientation and / or orientation in typical use shown in the figures. Nothing herein should be construed as requiring a specific three-dimensional or spatial orientation of a structure to be included within the claims.

[0015] Figures 1–3 illustrate exemplary tote bags that may be configured to carry or contain a variety of items. A tote bag may generally include an outer shell 216, shoulder straps 218, hand straps 210, a base 215, an opening, and a storage compartment 504. As shown in Figures 1 and 2A, the outer shell 216 forms a storage compartment 504 for receiving desired contents inside. Figure 2B illustrates a semi-rigid base 215 configured to keep the tote bag upright, whether or not there are contents in the storage compartment 504. The semi-rigid base may be configured to be oval, elliptical, rectangular, circular, or quadrilateral. As shown in Figure 1, various handles, straps, and webs (e.g., 218, 210) and MOLLE loops, as well as seams or bar tacks (e.g., 224, 222) may also be included for carrying, holding, or securing the tote bag, or for securing other items to the tote bag. Figures 1 and 2A also illustrate pockets 212 fitted inside the storage compartment 504 formed by the outer shell 216. Also shown in Figures 1 and 2A is a single seam 217 to which the outer shell is fused or joined to form a single independent compartment.

[0016] The tote bag may be configured to include an opening that is closed with a zipper or a waterproof zipper. In such a configuration, the tote bag is substantially water-resistant and can keep the desired contents dry for longer periods in humid conditions. The opening may also include various sealing devices in addition to a waterproof zipper, such as Velcro®, buttons, snaps, buckles, zippers, and multiple-folded excess material, to form a sealing part such as a roll-down sealing part, and it is also intended that sealing parts, metal or plastic clamps, and combinations thereof may be used to seal the opening. In one example, the tote bag may also be designed to retain water inside the storage compartment 504, and the tote bag may be configured to be “waterproof” from the outside to the inside. In other words, the tote bag may be “watertight” inside the outer shell 216 and the bottom inner liner 219, and configured to allow the transport of water or other liquids. In another example, the tote bag storage compartment is configured to include a drain, which penetrates the outer shell, and allows fluid to drain from the storage compartment. Such a configuration allows the user to easily wash or rinse the tote bag storage compartment with a hose, electric washer, or other cleaning device, and allows water to drain from the tote bag.

[0017] Figure 2A also illustrates a reinforcing patch 220, which in some examples may be welded or fused to the outer shell 216 and strap 218, and in other examples may be connected to the outer shell by joining the strap to the patch 220. In one example, the joining material may be nylon. The outer shell and inner liner may be manufactured from materials that are antimicrobial or antifungal. The tote bag may also be manufactured from materials that are water-resistant or waterproof in order to keep the contents stored inside substantially dry.

[0018] Figure 3 illustrates a right front view of an exemplary tote bag. The tote bag includes a shoulder strap 218 and a hand strap 210. Also illustrated are the upper joint 503 and the bottom tape fabric 502. Also visible are a single outer shell seam 217, outer upper tape fabric 501a, and inner upper tape fabric 501b. The strap 218 further includes MOLLE loops 224 and a seam 222. However, the MOLLE loops 224 do not necessarily have to be MOLLE and may be constructed in different shapes and sizes depending on their desired use. The strap 218 and the MOLLE loops 224 may be sewn to an outer shell reinforcement patch 220, which is welded to the outer shell 216.

[0019] Figures 4A and 4B illustrate the bottom view of the tote bag and illustrate schematic diagrams of enlarged sections of the cross-sectional view of the semi-rigid base structure. As shown in Figures 4A and 4B, the tote bag may include a TPU-coated nylon bottom tape fabric 221 welded to the base 215 and the outer shell 216 and base outer shell 226. The bottom inner liner 219 is also welded to the outer shell 216. The welds 227 are illustrated in Figures 4A and 4B. In addition, a compression-molded EVA having a TPU-coated nylon laminate 225 and a PE foamed base 223 is laminated between the bottom inner liner 219 and the base outer shell 226. The base 215 can provide structural integrity and support to the tote bag when it is placed on a surface, keeping the bag upright whether or not there are contents inside the storage compartments.

[0020] In one particular example, a portion of the base may be formed by injection molding. Additionally, in one example, a foamed base 223, which may be formed from EVA foam, may be fixed to the bottom of the inner bottom liner 219 by lamination, polymer welding (e.g., RF welding), stitching, or adhesive. The base outer shell 226 may be fixed to the compression-molded EVA 225 by polymer welding (e.g., RF welding), stitching, or adhesive. Similarly, the compression-molded EVA 225 may be fixed to the foamed base 223 by polymer welding (e.g., RF welding), stitching, or adhesive.

[0021] In one example, as shown in Figures 5A and 5B, the tote bag includes a storage compartment 504, which includes a first pocket 212. The first pocket 212 may be welded to the inside of the tote bag inside the storage compartment. In one example, the first pocket 212 includes a zipper 228, a zipper slider 229, and a paracord puller 230 having heat shrink tubing. The puller may also be formed from cloth, string, or rope. The puller may also be metal, alloy, composite, ceramic, or plastic, along with other suitable materials. In another example, the zipper 228 is waterproof, and the first pocket is configured to be waterproof when the zipper is closed. In one particular example, the waterproof zipper may be made of plastic or other non-metallic teeth to prevent damage when removing items from the first pocket 212. The first pocket is intended to be able to form a seal such as a roll-down seal, a seal, a metal or plastic clamp, and a combination thereof, by including various sealing devices in addition to a waterproof zipper, such as hook and loop, buttons, snaps, buckles, zippers, and multiple-folded excess material. The pocket may also be made of transparent material so that the user can see the contents inside the pocket without opening the zipper. In yet another embodiment, the tote bag includes a second pocket inside the storage compartment of the tote bag, directly opposite the first pocket. The second pocket may be welded to the storage compartment, and the second pocket may also be made of transparent material so that the contents inside the pocket can be seen. Both the first and second pockets may be made of mesh material so that the user can easily visualize the contents of the pockets. Both the first and second pockets may be fixed or attached to the storage compartment 504 by using any other method disclosed herein or any known method, such as polymer welding, stitching, or other adhesives.

[0022] Various materials may be used to constitute the components of the tote bag of this disclosure. In one particular embodiment, as shown in Figures 2A, 2B, 3, 4, and 5, the tote bag components are made of the respective materials outlined in Table 1 below. In one example, the tote bag can generally be folded into a semi-rigid base or collapsed for easy storage and transport. [Table 1]

[0023] In one example, as shown in Figures 6A and 6B, the tote bag includes a shoulder strap 218 and a hand strap 210. The shoulder strap may also include MOLLE loops 224. Additionally, as shown in Figures 6A and 6B, webbing formed as MOLLE loops 224 may be sewn onto the straps 218 and 210 at the front and back of the tote bag. The MOLLE loops 224 can be used to attach items (e.g., carabiners, dry bags) to the tote bag. The hand straps 210 can also provide the user with another option for securing the tote bag to a structure.

[0024] In another example, the shoulder strap 218, the hand strap 210, and the MOLLE loop 224 may be constructed from nylon webbing. Other materials may include polypropylene, neoprene, polyester, Dyneema, Kevlar®, cotton fabric, leather, plastic, rubber, or rope. The shoulder strap 218 and the hand strap 210 can be attached to the outer shell 216 by sewing, adhesive, or polymer welding. Furthermore, as shown in Figure 6A, the shoulder strap may include a webbing seam 505 hidden behind the strap. In addition, Figure 6B shows a perspective view from a single pocket seam 217 facing the user on the left side of the tote bag, with the seam 217 located on only one side of the tote bag. Also shown in Figures 6A and 6B are the upper joint 503, the bottom tape fabric 502, the outer upper tape fabric 501a, and the base 215. Various stitching, seam, and joining patterns are also shown on the exemplary tote bag in Figures 6A and 6B.

[0025] In one example, as shown in Figures 7A and 7B, the tote bag includes a shoulder strap 218 and a hand strap 210. The shoulder strap is attached to a reinforcement patch 220, which is welded to the outer shell. In one example, the reinforcement patch 220 extends above and below the upper joint 503, as shown in Figures 7A and 7B. The reinforcement patch 220 may include welds of 0.25 cm, 0.5 cm, 0.75 cm, 1.0 cm, 1.5 cm, 1.75 cm, or 2.0 cm around the periphery of the patch.

[0026] In another example, as shown in Figures 8A–8C, the tote bag includes a shoulder strap 218 and a hand strap 210. The strap is constructed by joining together three materials or sections of nylon webbing and includes an outer shoulder strap 218, a hand strap 210 facing inward toward the inside of the tote bag, and an intermediate hand strap reinforcing layer 211. In another example, as shown in Figure 8C, the shoulder strap 218 is at least 50mm x 1.5mm nylon webbing, the hand strap reinforcing layer 211 is at least 25mm x 2mm nylon webbing, and the hand strap 210 is uncoated nylon. See Table 1. In another example, as shown in Figure 8D, the construction of an alternative hand strap 210 includes an internal rigid or semi-rigid support rod 301 to thicken and reinforce the hand strap 210 attached to the shoulder strap 218. In an extended cross-sectional view, one or two rods 301 are housed within a layer of webbing 303 forming a hand strap 210. In another example, the rods 301 are housed within a layer of webbing 303 surrounded by another layer of webbing 302 forming the hand strap 210. In yet another example, a seam 304 sewn between the rods separates them. The rods 301 may be made of foam, polypropylene, neoprene, polyester, Dyneema, "Kevlar", cotton fabric, leather, plastic, rubber, wood, metal, or rope. In yet another example, the hand strap 210 is secured to a tab 305 by stitching, adhesive or polymer welding, which is then secured to a shoulder strap 218 by stitching, adhesive or polymer welding.

[0027] In yet another example, as shown in Figures 9 and 10, the tote bag may be of various dimensions. In one example, the shoulder strap is configured to remain above the horizontal plane of the base when the tote bag is carried by the hand strap. In another example, the hand strap 210 may form a U shape, each including a first vertical section 601, a second horizontal section 602, and a third vertical section 603, and in one example, at least the first and second vertical sections are attached to the shoulder strap 218. In yet another example, the shoulder strap 218 may define a first length 604 above the opening of the tote bag, and the hand strap 210 may be positioned below the midpoint along the first length of the shoulder strap 218. In yet another example, the shoulder strap 218 defines an upper handle 606, and the hand strap 210 defines a lower handle, with the distance between the upper and lower handles being a second length 605, where the second length is less than the first length. In this example, the second length 605 may be less than the height of the bag 607. In yet another example, the length 604 of the shoulder strap 218 is less than the height of the bag 607. In yet another example, the shoulder strap 218 is at least 70% of the height of the bag. In one particular example, the tote bag includes width and height, with the width being at least 65% of the height of the bag. The outer shell 216 may include a design 232, such as a logo or name, which may be attached directly to the material, molded into it, or embossed.

[0028] Additionally, as illustrated in Figures 11A and 11B, the bottom portion of the tote bag may include a base 215, which contributes to the structural integrity of the tote bag. The base 215 may also provide additional protection around the bottom of the tote bag. In one example, a portion of the base 215 may be formed from EVA foam 225. The base 215 may include a design, such as a logo or name, which may be molded directly into the material or embossed. The base 215 may also include a base outer shell 226 made of 1680D nylon with single-sided PU or other suitable material. Additionally, the bottom tape fabric 502 may be nylon, and the nylon is double-sided and at least one-color TPU. See Table 1.

[0029] In further examples, as shown in Figures 12 to 14A to 14C, the tote bag may come in a variety of dimensions. In other examples, the storage compartment 504 has a capacity of at least 20L. In other examples, the tote bag includes storage compartments having capacities of 5L, 10L, 15L, 20L, 25L, 30L, 35L, 40L, 45L, or 50L. In other examples, as shown in Figures 14A and 14C, the tote bag includes internal or external closing devices 235a and 235b attached to the inner upper tape fabric 501b. The closing devices 235a and 235b may be metal, alloy, composite, ceramic, plastic, or other suitable material.

[0030] As shown in Figures 13A–13B, the hand strap 210 may form a U shape, each including a first vertical section, a second horizontal section, and a third vertical section, with at least the first and second vertical sections attached to the shoulder strap 218. The tote bag also includes the shoulder strap 218 and upper joints 503 and 501b that extend over the upper tape fabric 501a. Also integrated on the front of the shoulder strap 218 and outer shell 216 are MOLLE loops 224. Various joints or seams are shown in the extended views of Figures 12A–12B and 13A–13B. These include seams or bar tackings 222 as well as back basting stitches 231 and hidden web seams 505. The outer shell 216 may be configured to support one or more optional handles or straps (e.g., 210, 218). In this regard, the outer shell 216 may also include a number of reinforcing areas or patches 220 configured to assist in structurally supporting optional handles or straps (e.g., 210, 218). The handles or straps (e.g., 210, 218) and other accessories may be sewn using thread 222, but these threads 222 do not, in one example, extend through the outer shell 216 into the storage compartment. Rather, the threads are sewn to the patches 220, and the patches 220 may be RF-welded to the outer shell 216. However, the handles or straps may be attached to the patches 220 and / or to the outer shell 216 by any other method disclosed herein or by any known method such as polymer welding, suturing, or other adhesives.

[0031] In another example, the tote bag may include two straps or carrying handles 210 that connect to the front and back of the outer shell 216 of the tote bag. In one particular example, a shoulder strap 218 may include additional padding to facilitate carrying the tote bag over the shoulder. The hand straps or handles 210 provide the user with another option for gripping and carrying the tote bag in such a manner that the shoulder straps 218 do not extend below the horizontal bottom of the base 215 of the tote bag (e.g., the bottom of the bag).

[0032] The carrying strap 210 may also incorporate rings, carabiners, or other attachment devices. These devices may be attached to the carrying strap or carrying handle 210 by stitching, adhesive, or polymer welding and may be used to help secure or tie the tote bag to other structures such as vehicles, instruments, camping equipment, or various items such as keys, water bottles, additional straps, bottle openers, tools, and other personal belongings. The carrying straps may also be attached to one another by incorporating various sealing or connecting devices, such as hook-and-loops, buttons, snaps, buckles, or zippers, seals, metal or plastic clamps, and combinations thereof.

[0033] Additionally, as shown in Figures 13A and 13B, webbing formed as loops or MOLLE loops 224 can be sewn onto the shoulder strap 218 and also form a hand strap 210 on the back of the tote bag. Again, the MOLLE loops 224 can be used to attach items (e.g., carabiners, dry bags) to the tote bag. The hand strap 210 can also provide the user with another option for securing the tote bag to a structure.

[0034] In one example, the hand strap 210 and shoulder strap 218 and MOLLE loop 224 may be made of nylon webbing. Other materials may include polypropylene, neoprene, polyester, Dyneema, "Kevlar", cotton fabric, leather, plastic, rubber, or rope. The hand strap 210 and shoulder strap 218 can be attached to the outer shell 216 or reinforcement patch 220 by sewing, adhesive, or polymer welding. The MOLLE loop 224 can be configured to accept a variety of items or a group of corresponding hooks that can be attached to any surface of various items such as fishing lures, keys, bottle openers, card holders, tools, and other personal belongings. In another example, the outer shell 216 may include a patch or logo 232 that can include a logo, company name, personalization, or other customization. The patch or logo 232 may be washable, UV resistant, and resistant to discoloration.

[0035] In certain examples, polymer welding techniques include both external and internal methods. External or thermal methods may include hot gas welding, hot wedge welding, hot plate welding, infrared welding, and laser welding. Internal methods may include mechanical welding and electromagnetic welding. Mechanical methods may include spine welding, stir welding, vibration welding, and ultrasonic welding. Electromagnetic methods may include resistance, implant, electrofusion welding, induction welding, dielectric welding, RF (radio frequency) welding, and microwave welding. Welding can be performed on a flat or horizontal surface to maximize the effect of polymer welding on the constituent materials. As a result, a robust watertight seam can be created that prevents water or fluid from entering or leaving the storage compartment 504.

[0036] In one particular example, the outer shell 216 and the bottom inner liner 219 may be composed of double-layered TPU nylon fabric. The nylon fabric can be used as the base material for the bottom inner liner 219 and the outer shell 216 and may be coated on both sides with TPU lamination. The TPU nylon fabric used in one particular example is 0.1 to 1.0 mm thick, waterproof, and has antimicrobial additives that meet all Food and Drug Administration requirements. However, the fabric used to construct the tote bag is intended to incorporate antimicrobial materials to create a mold-free environment where food contact surfaces are safe. In one particular example, the nylon may be 840d nylon with TPU. Alternative materials used to manufacture the inner bottom liner 219 and the outer shell 216 include PVC, TPU-coated nylon, coated fabrics, and other weldable and waterproof fabrics. See Table 1.

[0037] The foamed base 223 can be manufactured from an NBR / PVC compound or any other suitable compound. In addition, the tote bag may also include a compression-molded EVA 225 having a TPU-coated nylon laminate 226 layer. The compression-molded EVA 225 may be replaced with foam, plastic, metal or other material. In one example, the base 215 is at least 6 mm thick. Additionally, as shown in Figures 4A-4B and Table 1, the compression-molded EVA 225 and the foamed base 223 may each be 3 mm thick. The base outer shell 226 is laminated to the compression-molded EVA 225, but in an alternative example, the base outer shell 226 may be attached to the bottom of the compression-molded EVA 225 by co-molding, polymer welding, adhesive, or any known method.

[0038] Figures 15–21 show alternative examples of tote bags that may have the same structure and function as described above, but may have different shapes or configurations. In one example, as shown in Figures 16 and 17, the tote bag may have a trapezoidal shape or configuration. In another example, the tote bag may taper from the top to the bottom of the bag. Additionally, as shown in Figures 15, 18, and 19, the tote bag may be equipped with snaps 233 to fasten each pair of straps (i.e., 210, 218) together. This facilitates easy carrying of the bag by the bottom handle. As shown in Figures 16 and 17, the outer shell 216 may include a design or patch 232, such as a logo or name, which may be attached directly to the material, molded, or embossed, and may be removable (i.e., from a hook-and-loop patch 234). The design or patch may be attached by welding, sewing, gluing, or otherwise secured. The design or patch 232 may be attached, for example, by hook and loop, button, snap, buckle, zipper, seal, metal or plastic clamp, and combinations thereof, and therefore may be removable. The tote bag may have the design or patch 232 on one side of the bag on the outer shell 216, or on both sides of the tote bag, as shown in Figures 16 and 17. In other examples, the design or patch may be permanently fixed to one side or both sides of the tote bag. In other examples, the design or patch may be detachable on one side or both sides of the tote bag. In yet another example, one side of the tote bag may include a permanently fixed design or patch, and the other side may include a detachable design or patch. In other examples, the design or patch 232 may be configured to include a pocket that allows the user to insert a bag label, business card, or identification tag containing personal or other contact information such as name, address, email address, telephone number, etc.

[0039] In another example, a method for forming a tote bag may include forming an outer shell, installing a bottom inner liner onto the outer shell, and securing the bottom inner liner to the outer shell, thereby forming storage compartments. The method may also include forming a semi-rigid base, which consists of a base outer shell made of compression-molded EVA, a PE foam base, and a TPU-coated nylon laminate covering the semi-rigid base. The method may also include securing the base outer shell to the outer shell and attaching several straps to the outer shell.

[0040] The method may also include a bonding material which is nylon, the bonding material which is sewn to the outer shell / reinforcement patch, and the patch which is then welded to the outer shell. The method may also include forming an inner bottom liner which is welded to the outer shell, and the outer shell and base outer shell which are welded to the bottom tape fabric.

[0041] The method may also include forming an insulating layer on at least a portion of the first and second rectangles, and forming a first rectangle with a larger area than the second rectangle. The method may also include securing the bottom inner liner to the lower outer shell by welding. The method may also include forming a first pocket, which includes a zipper and is welded to the inner outer shell of the storage compartment, and forming a second pocket, which is welded to the inner outer shell of the storage compartment opposite the first pocket.

[0042] An exemplary method may include forming an outer shell having a single vertical seam. Another exemplary method may include attaching or fastening a strap to multiple reinforcing patches, which are then welded to the outer shell. The method may also include attaching multiple MOLLE loops to the strap. The method may also include forming a strap by joining three nylon strap components together, and then joining the strap to multiple patches welded to the outer shell. The method may also include forming a semi-rigid base portion by injection molding.

[0043] Figures 22 and 23 illustrate alternative exemplary tote bags which may have the same structure and function as described above, but may have alternative internal configurations. The tote bag may include a storage compartment 504 and may also include a first pocket 212a and / or a second pocket 212b. The first pocket 212a may be welded to the inside of the tote bag inside the storage compartment. It is intended that the first pocket may form a seal such as a roll-down seal, a seal, a metal or plastic clamp, or a combination thereof, including various sealing devices in addition to a waterproof zipper, e.g., hook and loop, button, snap, buckle, zipper, multiple-folded excess material. The pocket 212a may also be made of transparent material so that the user can see the contents inside the pocket without opening the zipper. The first pocket 212a may also be made of mesh material so that the user can easily visualize the contents of the pocket. The first pocket 212a may be fixed or attached to the inner wall of the storage compartment 504 by using any other method disclosed herein, or any known method, such as polymer welding, stitching, adhesive, or a combination thereof. In other examples, the upper portion of the inner pocket 212a may be positioned below the inner upper tape fabric 501b and / or below the upper joint 503. The inner upper tape fabric 501b may have a height equal to the height of the outer upper tap fabric 501 that surrounds the upper periphery of the outer shell and the opening of the tote bag. In some examples, the second pocket 212b may be welded to the inner wall of the tote bag wall inside the storage compartment 504. It is also intended that the second pocket 212b may form a seal such as a roll-down seal, a seal, a metal or plastic clamp, or a combination thereof, including various sealing devices in addition to a waterproof zipper, such as hook and loop, button, snap, buckle, zipper, multiple-folded excess material. Pocket 212b may also be made of a transparent material, so that the user can see the contents inside the pocket without opening the zipper.The second pocket 212a may also be made of mesh material, allowing the user to easily visualize the contents of the pocket. The second pocket 212b may be fixed or attached to the inner wall forming the storage compartment 504 by using any other method disclosed herein, or any known method, such as polymer welding, suturing, adhesive, or a combination thereof. In other examples, the upper portion of the inner pocket 212b may be positioned below the inner upper tape fabric 501b and / or below the upper joint 503.

[0044] As shown in Figures 22 and 23, the tote bag may include at least one divider or partition 401. In some examples, the divider 401 may be assembleable. In other examples, the divider 401 may include a pull tab 403 to assist the user in releasing or unfolding the divider 401 from a stowed or collapsed position to an extended position. In some examples, the tote bag may include a pair of collapsed dividers 401 that can be positioned on the side or side wall of the bag. In the stowed or collapsed position, the dividers 401 may fit coplanar with the interior side / wall of the tote bag. The pull tab 403 may also fit tightly to the inner upper tape fabric 501b.

[0045] As further shown in Figures 22 and 23, the tote bag may include an upper joint 503 that can be positioned over the outer tape fabric 501a and / or the inner upper tape fabric 501b. The upper joint 503 may be fastened to the outer shell and / or the outer upper tape fabric 501a and / or the inner upper tape fabric 501b by stitching, polymer welding, adhesive, or a combination thereof. The tote bag may include a closure device 235a positioned on the opposite side of the front of the bag and on the inner wall of the storage compartment. The closure device 235b may be positioned on the inner wall of the storage compartment opposite the closure device 235a. In some examples, the closure devices 235a and / or 235b may be attached to the inner upper tape fabric 501b. In other examples, the upper portions of the closure devices 235a and / or 235b may be positioned and / or attached below the upper joint 503. In yet another example, the closure device 235a and / or 235b may be sandwiched between the inner upper tape fabric 501b and the upper joint 503. In yet another example, the closure device 235a and / or 235b may be secured to the upper joint 503 and / or the inner upper tape fabric 501b by suture, adhesive, welding, or other mechanical means, or a combination thereof. In one example, the closure device 235a and / or 235b may be fabric loops, webbing loops, MOLLE loops, or may be made of metal, alloy, composite, ceramic, plastic, polymer, or other suitable material, or a combination thereof.

[0046] In another exemplary embodiment, as shown in Figures 24–27, the closure devices 235a and 235b may include fasteners configured to engage with loops of material positioned on the opposite side of the fastener. As shown in Figure 24, the closure device 235b may engage with additional loops of webbing or other material 236. Loops of webbing 236 may engage with the upper joint 503. Webbing 236 may be attached to the upper joint 503 and / or the inner upper tape fabric 501b by sewing, adhesive, welding or other mechanical means. The closure device 235b may also include metal, plastic, wood, polymer, ceramic, or other composite fasteners. Fasteners 235b may be formed integrally with the loops of webbing 236. In some examples, the closure device 235b may be positioned above the zippers 228, zipper sliders 229, and pullers 230 of pockets 212a and 212b. As shown in Figures 26 and 27, the closure 235a may include loops of webbing, MOLLE loops, or other material configured to engage with fasteners 235b to substantially close the opening of the bag in order to prevent contents from spilling out of the storage compartment 504. The closure 235a includes additional sutures 237 to create a first opening 239a and a second opening 239b. The openings 239a and / or 239b may be configured to engage with the closure device 235b.

[0047] As shown in Figures 28 and 29, fastener 235b removably engages with a loop of material 235a to substantially secure and close the opening of the bag. When the closing devices 235a and 235b are in the engaged position, the width of the opening at the position of the closing devices 235a and 235b can be reduced to at least about 0.5 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, 4.0 cm, 4.5 cm, 5.0 cm, 5.5 cm, 6.0 cm, 6.5 cm, 7.5 cm to 8.0 cm, less than these numbers, equal to these numbers, or any number in these numbers. This configuration is advantageous because it allows the opening to be secured to prevent items from falling out of the bag and further allows an individual to retrieve items held by the divider / partition 401. The closing devices may include zippers, snaps, buttons, threads, pull cords, and combinations thereof.

[0048] As shown in Figure 30, the tote bag may include multiple articulated dividers or partitions 401. The dividers 401 may be configured to follow the outline of the outer shell and the sides of the storage compartment 504. The dividers 401 may be attached to the inner side walls of the shell by stitching, welding, adhesive, or a combination thereof. The top and bottom of the dividers 401 may be left unattached, allowing the user to pull tabs 403 to extend the dividers 401 from a stored or folded position to an extended position, as shown in Figure 31.

[0049] As shown in Figure 32, the divider 401 may remain unfolded or extended after the user pulls or pushes the divider 401 to the extended position. The divider 401 may be extended so that the storage compartment is divided into multiple sections, separating individual contents or groups of items from each other and into the interior of the storage compartment. For example, Figure 33 illustrates a first divider 401 in the extended position that creates two sections within the storage compartment 504 of the bag.

[0050] The divider 401 and pull tab 403 may be made of nylon with one or both sides having TPU, uncoated nylon, EVA, or a combination thereof. In some examples, the pull tab 403 may be made of nylon webbing or a loop of nylon webbing. In other examples, the divider 401 and / or pull tab 403 may have one side being TPU and the other side being PU. In other examples, a portion of the divider 401 or a portion of the pull tab 403 may be molded with a portion or side made of one-sided TPU and welded to the inner shell or attached to the divider, or can be welded. The pull tab 403 may be integral with the divider 401 or may be formed as a separate component and attached to the top of the divider 401. In other examples, the pull tab 403 may be attached to the divider 401 by lamination, polymer welding (e.g., RF welding), stitching, or adhesive. In some examples, the pull tab 403 may be attached to the upper interior portion of the divider 401 as shown in Figure 33. In other examples, the divider 401 may include a reinforcing layer or fold 404 along its upper boundary to increase its strength, durability, and rigidity. When the divider 401 is in a retracted or collapsed position, the reinforcing layer 404 may be positioned beneath the bottom of the inner upper tape fabric 501b. In other examples, the reinforcing layer 404 or the top of the divider 401 may be positioned in contact with the bottom of the inner upper tape fabric 501b, forming a smooth seam (i.e., non-overlapping components). The pull tab 403 may also include a raised line or fold on its upper boundary to assist the user's dexterity when attempting to expand or fold the divider 401. The raised lines or folds may also help the user locate the pull tab 403 without visual contact (i.e., by touch only). The tab 403 may also be shaped such as isosceles trapezoid, trapezoid, quadrilateral, oval, ellipse, rectangle, circle, or crescent to aid in the individual's dexterity when manipulating the divider 401. As shown in Figure 33, the divider 401 includes sides that are attached to the shell adjacent to the sides of the inner pocket 212.In some examples, the divider 401 may be attached to the side wall by lamination, polymer welding (e.g., RF welding), stitching, adhesive, "Velcro", buttons, snaps, buckles, zippers, or other mechanical means. In some examples, the divider may be removable. In other examples, the divider 401 may share seams, stitching, or welds with the sides of the inner pocket 212. In other examples, the sides of the divider 401 may form the sides of the inner pocket 212a and / or 212b.

[0051] In an alternative embodiment, as shown in Figure 34, the insert 400 may be configured to be detachably attached to the internal storage compartment 504 of the tote bag disclosed herein.

The internal pockets 412a and 412b may include the same components and may be constructed in the same manner as the internal pockets 212a and 212b described above.

[0052] Figures 35A and 35B illustrate front and rear views of the insertion section 400. Internal pockets 412a and 412b are positioned on the front and rear panels 406 and may be configured as pockets 212a and 212b and have the same characteristics. The front and rear panels 406 may engage with the end panel 405. Panel 406 may be attached to the end panel 405 by lamination, polymer welding (e.g., RF welding), stitching, adhesive, "Velcro", buttons, snaps, buckles, zippers, or other mechanical means. In some examples, the end panel 405 may be attached directly to the sides of pockets 412a and 412b by lamination, polymer welding (e.g., RF welding), stitching, adhesive, "Velcro", buttons, snaps, buckles, zippers, or other mechanical means.

[0053] Furthermore, as shown in Figures 35A, 35B, 36A, 36B, 36C, and 36D, the insertion tab 409 may be attached to the end panel 405. The insertion tab 409 may be attached to the end panel 405 by lamination, polymer welding (e.g., RF welding), sutures, adhesive, or a combination thereof. The insertion tab 409 may be equipped with handles, straps, webbing, MOLLE loops, sutures, or bars for supporting, holding, manipulating, or securing the insertion section 400, or for carrying items such as rings, carabiners, or other attachment devices.
