Description

Technical Field

[0001] This disclosure relates primarily to the field of containers and carrying devices, and more particularly to a waterproof or water-resistant floating bag containment system or carrier having a sealable compartment for electronic devices within a larger carrying compartment, optionally including a light-transmitting or transparent cover or window to allow access from outside the container to a touchscreen user interface of the electronic devices stored in the sealed compartment, and smaller, separate, concealed waterproof pockets or compartments for storing credit cards and / or other smaller items. Background Technology

[0002] Various containers, bags, and carriers are known for storing and transporting goods. For example, "waterproof bags" and "dry bags" are commonly used to keep items stored inside dry when used in environments where exposure to water or moisture is possible, such as during boating, rafting, hiking, camping, fishing, or other activities. A typical bag takes the form of a rectangular pouch made of waterproof or water-resistant material and includes a top closure at one end for access to the bag's internal storage compartments. After items are placed inside the bag's storage compartments, the top can be securely closed by rolling snaps and clamping together. The top closure and the waterproof or water-resistant material are designed to prevent or reduce water from entering the storage compartments.

[0003] Different containers (including bags) offer varying levels of protection for their contents. The International Electrotechnical Commission (IEC) provides guidelines for the levels of water and dust protection offered by containers based on the international standard IEC 60529 (published in the European Union as EN 60529 by the European Committee for Electrotechnical Standardization (CENELEC)). This standard uses "IP" codes to indicate different levels of protection. The first digit after "IP" indicates the level of protection provided by the enclosed space against access to hazardous components (e.g., electrical conductors, moving parts) and against the ingress of dust or other solid foreign objects; the second digit indicates the level of protection against water ingress. For example, a container rated IEC 60529 "IP68" protection has a dust protection level of 6 (dustproof, no dust ingress) and a water ingress level of 8 (submersion in 1 meter (approximately 39'') or deeper in water for 30 minutes or more).

[0004] While some previously known waterproof bags can provide adequate protection for wallets and other personal items, many are not designed with the level of reliability and convenience required to securely store and access valuable electronic devices such as smartphones. Furthermore, traditional waterproof bags often require the user to open the main compartment to retrieve smaller items, increasing the risk of water exposure to the main contents. Additionally, some known containers lack sufficient buoyancy to float with the weight of the mobile phones and / or other items contained within. Moreover, in some situations, it may be desirable for some contents to be visible and accessible from an external vantage point, while other contents may be concealed for security or privacy reasons.

[0005] Therefore, a need for improved containment systems has been identified. This disclosure is primarily directed to providing containment systems that meet these and other needs. Utility Model Content

In some embodiments, the containment system takes the form of a waterproof bag made of one or more waterproof materials and has a main storage compartment configured to hold a mobile phone, and separate, concealed or hidden side pockets positioned externally for easy access to small items such as credit cards. The main storage compartment includes a resealable access opening incorporating a resealable waterproof or leak-proof closure. In various embodiments, the side pockets may include a zipper lock closure with a Velcro tab, such as a plastic zipper channel closure (similar to Ziploc). ® The bag may feature a zippered passage closure (see, for example, U.S. Patent No. 3,473,589, which is incorporated herein by reference), a concealed zipper lock closure, or a waterproof zipper, each configured to allow access to the contents without opening the main compartment while preventing water ingress. In other embodiments, the housing may include a transparent or light-transmitting window aligned with the main compartment, allowing visibility of a mobile phone stored in the bag and touchscreen operation of it. One or more carrying straps may be provided, optionally including interchangeable attachment positions that allow for a variety of different carrying configurations.

[0007] The sample bag according to this disclosure addresses some of the shortcomings of previously known products by incorporating a dedicated side pocket specifically designed for storing small items such as credit cards.

[0029] Referring now to the accompanying drawings, in all the views, the same reference numerals denote corresponding parts. Figures 1 to 4B An example embodiment of a waterproof or highly water-resistant bag 10 according to exemplary embodiments of the present disclosure is shown. In the depicted example embodiment, the bag 10 includes a generally bag-shaped outer body or shell 12, and defines an internal main storage compartment or chamber 14 therein, the compartment or chamber 14 being configured to accommodate an electronic device 100 (such as a smartphone) or any suitable item. In some example embodiments, the outer body or shell 12 includes a flat bag construction or other construction, the flat bag construction having rectangular front and rear wall panels 22, 24.

[0030] The bag 10 also includes an opening 30 for providing access to the internal main storage compartment 14. For example, the opening 30 is located on or near the top of the outer body or casing 12, such as... Figures 1 to 3As best shown in the diagram. In some example embodiments, the opening 30 extends across the entire top of the body or housing 12. Optionally, a coupling mechanism may be provided, which attaches around the top exterior of the body or housing 12 to provide a closure typically in the form of a waterproof bag. The coupling mechanism may take the form of a clamping or rolling coupling mechanism having first and second clamping or rolling coupling elements 34a, 34b that engage with each other, the first and second clamping or rolling coupling elements 34a, 34b being attached to secure as... Figures 1 to 3 The top of the enclosed outer body or shell 12 shown.

[0031] Preferably, the outer body or shell 12 is formed of a waterproof or highly water-resistant flexible material, or flexible waterproof material, such as waterproof flexible polyvinyl chloride (PVC), thermoplastic polyurethane (TPU), or combinations thereof. In alternative embodiments, various other construction materials may also be used.

[0032] The outer body or housing 12 can be formed as a single piece of material, for example, by molding. As another example, the outer body or housing 12 may comprise one or more sheets or plates of material continuously bonded or attached to each other by radio frequency (RF) welding, waterproof adhesives, thermal welding, or other attachment methods. In this example, preferably, the attachments used at any seams combine thin, flexible materials with good bond strength, watertight seal, and a good appearance to provide a waterproof or highly water-resistant enclosed space.

[0033] The bag 10 also includes a secondary storage compartment 40, which is integrated into the outer casing 12 and positioned externally relative to the internal main storage compartment 14, such as... Figure 4A and Figure 4B As best shown in the diagram. The secondary storage compartment 40 includes an opening 42, which is located at one side edge of the housing 12, such as... Figure 1 and Figure 2 As shown. Preferably, the secondary storage compartment 40 is configured to store small personal items, such as cards, keys, or cash, and allows access to these items without opening the main compartment 14. The secondary storage compartment 40 includes an enclosed space formed by a front panel 44, a rear panel 46, and a resealable access opening 42. The front panel 44 faces the inner surface of the front wall panel 22 of the housing 12, and the rear panel 46 faces the rear wall panel 24 of the housing 12. The enclosed space is sealed around the bottom and side edges of the secondary storage compartment 40. The resealable access opening 42 is located at least along the side of the housing 12 on the side of the secondary storage compartment 40 for inserting and removing items from its internal storage compartment 40. The enclosed space forms a cavity 401 ( Figure 4A ( ), to accommodate these small personal items.

[0034] like Figure 4A and Figure 4B As shown, the front panel 44 and the rear panel 46 of the secondary storage compartment 40 can be formed as a single piece of material. The secondary storage compartment 40 can be internally attached to the wall panels of the outer casing 12.

[0035] Preferably, a second re-sealing, re-sealing waterproof or leak-proof closure is provided at or near the access opening 42. It can be seen that the access opening 42 may be located at or near the top of the outer body or housing 12, oriented at, for example, an angle of substantially 90 degrees relative to the opening 30.

[0036] In one exemplary embodiment, optionally, a second re-closing, re-sealing waterproof or leak-proof closure is disposed on or near the side exterior of the outer body or housing 12. In an example embodiment, the second re-closing, re-sealing waterproof closure may be a plastic zipper channel or a press-fit closure (similar to Ziploc). ® The bag is in the form of a convex-concave structure that can be engaged with each other by applying force with the user's fingers.

[0037] The second re-closing, re-sealing waterproof closure is configured for repeated closure and re-sealing for repeated use. For example, the second re-closing, re-sealing waterproof closure may include either a push-to-close zipper or a sliding zipper. In some example embodiments, the push-to-close zipper may be concealed within the secondary storage compartment 40.

[0038] An example of a press-to-close zipper can be found, for example, in U.S. Patent No. 3,473,589, which is incorporated herein by reference.

[0039] Another example of a press-to-close zipper can be found in Figure 4A As shown in the figure, a monorail type second re-closing, re-sealing waterproof closure is presented. The user presses the convex closure member 48c into a single track or recess (concave structure) formed by closure members 48a and 48b to engage and seal the closure, thereby closing and sealing the opening 42. When it is necessary to open the opening 42, the user separates the closure member 48c from the closure members 48a and 48b to release the seal and open the opening 42.

[0040] Another example of a press-to-close zipper can be found in Figure 4B As shown in the figure, a dual-track type second re-sealing, re-retaining waterproof closure is illustrated. The user presses two convex closure members 48a and 48b into a dual-track structure having two recesses (concave structures) formed by closure members 48c, 48d, and 48e to engage and seal the closure, thereby closing and sealing the opening 42. When it is necessary to open the opening 42, the user separates the closure members 48a and 48b from the closure members 48c, 48d, and 48e to release the seal and open the opening 42.

[0041] In some example embodiments, preferably, when closed and sealed, the second re-closing, re-sealing waterproof closure provides an IEC 60529 IP68 waterproof and dustproof seal at the opening 42 to prevent water from entering the secondary storage compartment 40, thereby protecting the items stored therein.

[0042] In some embodiments, the secondary storage compartment 40 may include a Velcro ® The plastic zipper channel of the pull tab mechanism 50 presses to seal the closure (e.g., a second re-closing, re-sealing waterproof component). After engaging and sealing the second re-closing, re-sealing waterproof component, the user presses the convex pull tab member 50a and the concave pull tab member 50b together to engage and seal the mechanism 50, thereby closing and sealing the opening 42, and pulls the pull tab members 50a and 50b apart to release the seal and open the mechanism 50. ® The pull tab 50 is configured for easy use in the opening of a secondary storage compartment to provide a tactilely accessible grip point for quick access. Preferably, Velcro... ® The pull tab member 50 is configured to be re-closed and re-sealed for repeated use.

[0043] In some example embodiments, the secondary storage compartment and its closure / sealing element are positioned and configured in a manner that is not immediately visible or noticeable to provide a more secure concealed storage mechanism. For example, the closure / sealing element of the secondary storage compartment may be positioned along or adjacent to the edge of the body to appear as part of the seam between the front and rear panels, may have a color that matches the surrounding surface, and / or the body of the bag covering the secondary compartment may be opaque to prevent observation of its contents from an external vantage point.

[0044] In an example embodiment, the bag 10 may further include a main window 90, which is formed as a rear wall panel 24 extending through the outer shell 12 of the main storage compartment 14. The main window 90 may be a cutout or a transparent or light-transmitting portion on the rear wall panel 24, and thus may also be referred to as a main transparent window. The main window 90 is generally positioned aligned with an area of ​​the main storage compartment where electronic devices may be stored, allowing a user to view the contents of the bag through the window and optionally operate the touchscreen or other user interface of the electronic device. In embodiments where the main window 90 is a cutout, a continuous and sealed attachment is formed around the window between the material of the front wall panel and the transparent window material, for example, by radio frequency (RF) welding, waterproof adhesive, thermal welding, or other waterproof sealing methods.

[0045] In another embodiment, the bag 10 further includes a secondary window 92 formed through the front wall panel 22 of the housing 12, positioned opposite the main transparent window 90 on the rear wall panel 24. The secondary window 92 is aligned with the camera area 101 of the electronic device 100 stored within the internal main storage compartment 14, ensuring the camera lens is visible and unobstructed from the outside of the bag. This configuration allows the user to take photos or videos using the device's built-in camera without removing it from the bag, thus maintaining the device's waterproof protection. The secondary window 92 may be made of a light-transmitting, optically transparent material, such as TPU or polycarbonate, chosen to minimize deformation and glare while maintaining waterproof integrity. Preferably, the secondary window 92 is sealed to the front wall panel 22 using a waterproof attachment method such as RF welding, thermal bonding, or a waterproof adhesive. This dual-window configuration allows full use of the electronic device's touchscreen interface and camera functionality while keeping the electronic device securely enclosed within the bag. Figure 1 and Figure 3 As best shown, the sub-window 92 can be located below the sub-storage compartment 40, wherein the lowermost edge 402 of the sub-storage compartment 40 is a certain distance away from the uppermost edge 921 of the sub-window 92.

[0046] In some embodiments, the bag 10 further includes one or more buoyancy foam layers 70 disposed within the outer casing 12. Figure 4A and Figure 4B In one example, two foam layers 70 are arranged between the front wall panel 22 and the rear wall panel 24. In this example, a padding material is arranged between the front wall panel 22 and the rear wall panel 24, and the padding material may include a first inner padding 221 facing the front wall panel 22 and a second inner padding 241 facing the rear wall panel 24, or the padding material may be a single-piece material. As shown, one of the two foam layers 70 is arranged between the secondary storage compartment 40 and the first inner padding 221, and the other is arranged between the second inner padding 241 and the rear wall panel 24. As an example, the internal main storage compartment 14 may be surrounded by one or more foam layers 70 along at least a portion of its periphery and on at least one of its front and rear sides, wherein the front side faces the front wall panel 22 of the housing 12 and the rear side faces the rear wall panel 24. Figure 2 , Figure 4A and Figure 4B As shown, along its entire perimeter and on both the front and back sides, the internal main storage compartment 14 is surrounded by two foam layers 70.

[0047] As an example, one or more buoyancy foam layers 70 can be sealed between the front wall panel 22 and the rear wall panel 24 using waterproof attachment methods such as RF welding or lamination, thereby ensuring that the foam layer 70 remains dry and securely positioned.

[0048] The foam layer 70 is configured to provide buoyancy, allowing the bag 10 to remain afloat when placed in water, even when containing electronic devices and personal items. This feature enhances the bag's practicality in outdoor and aquatic environments such as boating, kayaking, or beach use. The foam layer 70 can be made of closed-cell polyethylene, EVA, or other lightweight, waterproof foam materials. Including the foam layer 70 does not interfere with the flexibility or usability of the bag 10 and can be configured to maintain a small profile to preserve the bag's compact shape factor.

[0049] Figures 5 to 8B Another example embodiment of a waterproof or highly water-resistant bag 110 according to exemplary embodiments of the present disclosure is shown, which is substantially similar to the bag in the foregoing embodiments, except as described below. In the depicted example embodiment, the bag 110 includes a generally bag-shaped outer body or shell 112, and defines an internal main storage compartment or chamber 114 therein, the compartment or chamber 114 being configured to accommodate electronic equipment or any suitable items. In some example embodiments, the outer body or shell 112 includes a flat bag construction or other construction, the flat bag construction having rectangular front and rear wall panels 122, 124.

[0050] The bag 110 also includes an opening 130, located, for example, on or near the top of the outer body or housing 112, for providing an access opening to the internal main storage compartment 114. In some example embodiments, the opening extends across the entire top of the body or housing 112. Optionally, a coupling mechanism may be provided, attached around the top exterior of the body or housing 112, to provide a closure typically in the form of a waterproof bag, wherein first and second clamping or rolling coupling elements 134a, 134b, engaging with each other, are attached to ensure a top closure, such as... Figures 5 to 7 As shown.

[0051] Preferably, the outer body or shell 112 is formed of a waterproof or highly water-resistant flexible material, or flexible waterproof material, including: flexible polyvinyl chloride (PVC), thermoplastic polyurethane (TPU), or a combination thereof. In alternative embodiments, various other construction materials may also be used.

[0052] The outer body or housing 112 can be formed as a single piece of material, for example, by molding. As another example, the outer body or housing 112 may comprise one or more sheets or plates of material continuously bonded or attached to each other by radio frequency (RF) welding, waterproof adhesives, thermal welding, or other attachment methods. In this example, preferably, the attachments used at any seams combine thin, flexible materials with good bond strength, watertight seal, and a good appearance to provide a waterproof or highly water-resistant enclosed space.

[0053] The bag 110 also includes a secondary storage compartment 140, which is integrated into the outer casing 112 and positioned externally relative to the internal main storage compartment 114, such as... Figure 8A and Figure 8B As best shown in the diagram. The secondary storage compartment 140 includes an opening 142, which is located at one side edge of the housing 112, such as... Figure 5 and Figure 6 As shown. Preferably, the secondary storage compartment 140 is configured to store small personal items, such as cards, keys, or cash, and allows access to these items without opening the main compartment 114. The secondary storage compartment 140 includes an enclosed space formed by a front panel 144, a rear panel 146, and a resealable access opening 142. The front panel 144 faces the inner surface of the front wall panel 122 of the housing 112, and the rear panel 146 faces the rear wall panel 124 of the housing 112. The enclosed space seals around the bottom and side edges of the secondary storage compartment 140. The resealable access opening 142 is located at least along the side of the housing 112 on the side of the secondary storage compartment 140 for inserting and removing items from its internal storage compartment 140. The enclosed space forms a cavity 141 ( Figure 8A ( ), to accommodate these small personal items.

[0054] like Figure 8A and Figure 8B As shown, the front panel 144 and the rear panel 146 of the secondary storage compartment 140 can be formed as a single piece of material. The secondary storage compartment 140 can be internally attached to the wall panels of the outer casing 112.

[0055] Preferably, a second re-sealing, re-sealing waterproof or leak-proof closure is provided at or near the access opening 142. As can be seen, the access opening 142 may be located at or near the top of the outer body or housing 112, oriented at an angle of, for example, substantially 90 degrees relative to the opening 130.

[0056] In one exemplary embodiment, optionally, a second re-closing, re-sealing waterproof or leak-proof closure is disposed on or near the side exterior of the outer body or housing 112. In an example embodiment, the second re-closing, re-sealing waterproof closure may be a plastic zipper channel or a press-fit closure (similar to Ziploc). ® The bag is in the form of a convex-concave structure that can be engaged with each other by applying force with the user's fingers.

[0057] The second re-closing, re-sealing waterproof closure is configured for repeated closure and re-sealing for repeated use. For example, the second re-closing, re-sealing waterproof closure may include either a push-to-close zipper or a sliding zipper. In some example embodiments, the push-to-close zipper may be concealed within the secondary storage compartment 140.

[0058] An example of a press-to-close zipper can be found, for example, in U.S. Patent No. 3,473,589, which is incorporated herein by reference.

[0059] Another example of a press-to-close zipper can be found in Figure 8A As shown in the figure, a monorail type second re-closing, re-sealing waterproof closure is illustrated. The user presses the convex closure member 148c into a single track or recess (concave structure) formed by closure members 148a and 148b to engage and seal the closure, thereby closing and sealing the opening 142. When it is necessary to open the opening 142, the user separates the closure member 148c from the closure members 148a and 148b to release the seal and open the opening 142.

[0060] Another example of a press-to-close zipper can be found in Figure 8B As shown in the figure, a dual-track type second re-sealing, re-reserving waterproof closure is presented. The user presses two convex closure members 148a and 148b into a dual-track structure having two recesses (concave structures) formed by closure members 148c, 148d, and 148e to engage and seal the closure, thereby closing and sealing the opening 142. When it is necessary to open the opening 142, the user separates the closure members 148a and 148b from the closure members 148c, 148d, and 148e to release the seal and open the opening 142.

[0061] In some example embodiments, preferably, when closed and sealed, the second re-closing, re-sealing waterproof closure provides an IEC 60529 IP68 waterproof and dustproof seal at the opening 142 to prevent water from entering the secondary storage compartment 140, thereby protecting the items stored therein.

[0062] In an alternative embodiment, bag 110 includes a secondary storage compartment 140 with a concealed access opening 142. The access opening 142 is integrated within a seam or crease of the outer casing 112, making it difficult to see when the bag 110 is viewed from the outside. This concealed construction improves the bag's aesthetics and provides an additional layer of security by obscuring the location of the secondary storage compartment 140. The concealed access opening 142 may be positioned along a side seam or beneath a flap in the material and may be combined with a resealable, re-sealed waterproof closure, including... Figure 8A The single-track type or Figure 8B The bag features a dual-track plastic zipper channel or a press-lock mechanism. This design allows users to carefully store and access small personal items, such as cards or keys, without compromising the bag's waterproof integrity.

[0063] In an example embodiment, the bag 110 may further include a main window 190, which is formed as a rear wall panel 124 extending through the outer shell 112 of the main storage compartment 114. The main window 190 may be a cutout or a transparent or light-transmitting portion on the rear wall panel 124, and thus the main window 190 may also be referred to as a main transparent window. The main window 190 is generally positioned aligned with an area of ​​the main storage compartment where electronic devices may be stored, allowing a user to view the contents of the bag through the window and optionally operate the touchscreen or other user interface of the electronic device. In embodiments where the main window 190 is a cutout, a continuous and sealed attachment is formed around the window between the material of the front wall panel and the transparent window material, for example, by radio frequency (RF) welding, waterproof adhesive, thermal welding, or other waterproof sealing methods.

[0064] In another embodiment, the bag 110 further includes a secondary window 192 formed through the front wall panel 122 of the housing 112, positioned opposite the main transparent window 190 on the rear wall panel 124. The secondary window 192 is aligned with the camera area of ​​an electronic device stored within the internal main storage compartment 114, ensuring the camera lens is visible and unobstructed from the outside of the bag. This configuration allows the user to take photos or videos using the device's built-in camera without removing it from the bag, thus maintaining the device's waterproof protection. The secondary window 192 may be made of a light-transmitting, optically transparent material, such as TPU or polycarbonate, chosen to minimize deformation and glare while maintaining waterproof integrity. Preferably, the secondary window 192 is sealed to the front wall panel 122 using a waterproof attachment method such as RF welding, thermal bonding, or a waterproof adhesive. This dual-window configuration allows full use of the electronic device's touchscreen interface and camera functionality while keeping the electronic device securely enclosed within the bag. Figure 5 and Figure 7 As best shown, the sub-window 192 may be located below the sub-storage compartment 140, wherein the lowermost edge of the sub-storage compartment 140 is a certain distance away from the uppermost edge of the sub-window 192.

[0065] In some embodiments, the bag 110 further includes one or more buoyancy foam layers 170 disposed within the outer casing 112. Figure 8A and Figure 8BIn one example, two foam layers 170 are arranged between the front wall panel 122 and the rear wall panel 124. In this example, a padding material is arranged between the front wall panel 122 and the rear wall panel 124, and the padding material may include a first inner padding 1221 facing the front wall panel 122 and a second inner padding 1241 facing the rear wall panel 124, or the padding material may be a single-piece material. A secondary storage compartment 140 may be formed by padding. As shown, one of the two foam layers 170 is arranged between the secondary storage compartment 140 and the first inner padding 1221, and the other is arranged between the second inner padding 1241 and the rear wall panel 124. As an example, the internal main storage compartment 114 may be surrounded by one or more foam layers 170 along at least a portion of its periphery and on at least one of its front and rear sides, wherein the front side faces the front wall panel 122 of the housing 112 and the rear side faces the rear wall panel 124. Figure 6 , Figure 8A and Figure 8B As shown, along its entire perimeter and on both the front and back sides, the internal main storage compartment 114 is surrounded by two foam layers 170.

[0066] As an example, one or more buoyancy foam layers 170 can be sealed between the front wall panel 122 and the rear wall panel 124 using waterproof attachment methods such as RF welding or lamination, thereby ensuring that the foam layer 170 remains dry and securely positioned.

[0067] The foam layer 170 is configured to provide buoyancy, allowing the bag 110 to remain afloat when placed in water, even when containing electronic devices and personal items. This feature enhances the bag's practicality in outdoor and aquatic environments such as boating, kayaking, or beach use. The foam layer 170 may be made of closed-cell polyethylene, EVA, or other lightweight, waterproof foam materials. Including the foam layer 170 does not interfere with the flexibility or usability of the bag 110 and can be configured to maintain a small profile to preserve the bag's compact shape factor.

As another example, the outer body or housing 212 may comprise one or more sheets or plates of material continuously bonded or attached to each other by radio frequency (RF) welding, waterproof adhesives, thermal welding, or other attachment methods. In this example, preferably, the attachments used at any seams combine thin, flexible materials with good bond strength, watertight seal, and a good appearance to provide a waterproof or highly water-resistant enclosed space.

[0072] The bag 210 also includes a secondary storage compartment 240, which is integrated into the outer casing 212 and positioned externally relative to the internal main storage compartment 214. The secondary storage compartment 240 includes an opening 242 located at one edge of the outer casing 212, such as... Figure 9 and Figure 11 As shown. Preferably, the secondary storage compartment 240 is configured to store small personal items, such as cards, keys, or cash, and allows access to these items without opening the main compartment 214.

[0073] The secondary storage compartment 240 includes an enclosed space formed by a front panel and a rear panel. Similar to the aforementioned design, the enclosed space seals around the bottom and side edges of the secondary storage compartment 240. The resealable access opening 242 is preferably located on the side of the secondary storage compartment 240, at least parallel to the side of the outer casing 212, for inserting and removing items from its internal storage compartments 240. Preferably, the secondary storage compartment 240 is attached to the inner surface of one wall panel of the outer casing 212.

[0074] In another embodiment, the secondary storage compartment 240 is equipped with a waterproof zipper mechanism 260, which is disposed, for example, externally on the front wall panel 222 or the rear wall panel 224 of the housing 212. That is, with Figure 4A , Figure 4B , Figure 8A and Figure 8B Compared to the internally arranged closures shown, the waterproof zipper mechanism 260 is exposed and can be seen by the user from the outside.

[0075] The waterproof zipper 260 is configured to provide a high-integrity seal against water ingress while allowing smooth and reliable access to the contents of the secondary storage compartment 240. The zipper 260 may be constructed of thermoplastic polyurethane (TPU) or other waterproof materials and may include a rubber treatment or laminated coating to enhance sealing performance. This embodiment is particularly suitable for users who require frequent access to the secondary storage compartment 240 while maintaining a high degree of water resistance. The waterproof zipper 260 may be positioned horizontally or vertically along the outer surface of the bag 210 and may include a pull tab or grip reinforcement feature for use in slippery conditions.

[0076] In an example embodiment, the bag 210 may further include a main window 290, which is formed as a rear wall panel 224 extending through the outer shell 212 of the main storage compartment 214. The main window 290 may be a cutout or a transparent or light-transmitting portion on the rear wall panel 224, and thus the main window 290 may also be referred to as a main transparent window. The main window 290 is generally positioned aligned with an area of ​​the main storage compartment where electronic devices may be stored, allowing a user to view the contents of the bag through the window and optionally operate the touchscreen or other user interface of the electronic device. In embodiments where the main window 290 is a cutout, a continuous and sealed attachment is formed around the window between the material of the front wall panel and the transparent window material, for example, by radio frequency (RF) welding, waterproof adhesive, thermal welding, or other waterproof sealing methods.

[0077] In another embodiment, the bag 210 further includes a secondary window 292 formed through the front wall panel 222 of the outer casing 212, positioned opposite the main transparent window 290 on the rear wall panel 224. The secondary window 292 is aligned with the camera area of ​​an electronic device stored within the internal main storage compartment 214, ensuring the camera lens is visible and unobstructed from the outside of the bag. This configuration allows the user to take photos or videos using the device's built-in camera without removing it from the bag, thus maintaining the device's waterproof protection. The secondary window 292 may be made of a light-transmitting, optically transparent material, such as TPU or polycarbonate, chosen to minimize deformation and glare while maintaining waterproof integrity. Preferably, the secondary window 292 is sealed to the front wall panel 222 using a waterproof attachment method such as RF welding, thermal bonding, or a waterproof adhesive. This dual-window configuration allows full use of the electronic device's touchscreen interface and camera functionality while keeping the electronic device securely enclosed within the bag. Figure 9 and Figure 11As best shown, the sub-window 292 can be located below the sub-storage compartment 240, wherein the lowermost edge of the sub-storage compartment 240 is a certain distance away from the uppermost edge of the sub-window 292.
