Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application 63 / 597,636 filed on Nov. 9, 2023, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION

[0002] Hydration systems have become an essential tool for athletes and outdoor enthusiasts, particularly in endurance sports such as cycling and triathlons. However, existing hydration solutions present several challenges that impact performance, comfort, and efficiency.

[0003] One of the primary issues with current hydration bladders is their lack of anatomical fit. This poor fit not only affects user comfort but also significantly impacts aerodynamics, which is a crucial consideration for cyclists and triathletes. High-performance athletes invest heavily in equipment that optimizes aerodynamics, such as bikes with internal routing. However, existing hydration packs, such as shown in FIG. 7B, often counteract these efforts by creating drag and disrupting the rider's aerodynamic profile. Weight is often another related critical factor for users of hydration packs. Current hydration packs are often heavy, which can negatively impact performance.

[0004] Many existing hydration solutions offer limited fluid capacity, which presents significant challenges for athletes and outdoor enthusiasts, particularly during long events or competitions. This limitation often necessitates more frequent refills, potentially disrupting performance and rhythm during activities. For instance, in endurance events like triathlons or long-distance cycling races, athletes may be forced to compromise their hydration strategy due to insufficient fluid storage capacity. The problem of limited capacity is further compounded by the difficulty in accessing and refilling hydration bladders, especially in competitive environments. Current designs often require time-consuming processes to replace or refill the bladder contents, which can be particularly problematic during races or other time-sensitive situations. This challenge is especially acute in competition environments where reducing the time to change the fluid contents of a hydration pack is of paramount importance.

[0005] The need for more rapid refilling of water is a critical consideration for athletes. In competitive scenarios, every second counts, and the ability to quickly replenish fluids can make a significant difference in performance outcomes. Current hydration systems often fall short in this regard, requiring users to remove the entire bladder from the pack, open it, refill it, and then reinsert it into the pack—a process that can be cumbersome and time-consuming. Relatedly, the difficulty in accessing bladders within backpacks presents additional challenges. Many existing designs require users to navigate through various compartments to reach the bladder, which can be particularly frustrating when time is of the essence. This issue is exacerbated by the fact that some hydration packs are designed with the bladder deeply embedded within the pack structure, making it even more challenging to access quickly. Many existing solutions involve separate components, such as a pack and a removable bladder. This redundancy in equipment can lead to increased weight, complexity, and potential points of failure.

[0006] The orientation of the drinking hose in existing hydration packs presents another related challenge. Many designs require users to manually reposition the hose with their hands to drink, which can be problematic and potentially dangerous, particularly when riding a road bike.

[0007] Another significant challenge associated with existing hydration systems like that shown in FIG. 7B is the issue of fluid sloshing during use. This problem can have detrimental effects on both the stability and aerodynamics of the hydration pack, particularly in high-performance athletic contexts such as cycling and triathlons. As athletes using such hydration systems move, the liquid within traditional hydration bladders tends to shift and slosh, creating unpredictable weight distribution and potentially disrupting the user's balance. This movement of fluid can be especially problematic in activities that require precise body control and stability. Furthermore, the sloshing effect can alter the pack's shape and profile, compromising its aerodynamic properties. For cyclists and triathletes who invest heavily in equipment to optimize their aerodynamic profile, this fluid movement can counteract those efforts, potentially impacting performance. The challenge of mitigating fluid sloshing while maintaining a lightweight and comfortable design has remained a persistent issue in the development of hydration systems for endurance sports.

[0008] Athletes in particular often further struggle to accurately monitor fluid levels in current hydration packs. This limitation can lead to unexpected dehydration or the need for unplanned stops to check and refill the bladder. Such lack of monitoring can also cause challenges during competitive events.

[0009] Current hydration packs do not effectively address the need for temperature regulation. It remains desirable to achieve a temperature mitigating effect on the wearer's back during the utilization of a hydration pack, which could help manage overall body temperature during physical activities.

[0010] As such, there remains a need for an improved mechanism for a human to carry fluids featuring improved aerodynamics, weight reduction, capacity optimization, ease of use, and cost-effectiveness. Addressing these challenges could significantly enhance the performance and experience, especially for athletes and outdoor enthusiasts who rely on these systems to maximize competitive advantages.SUMMARY OF INVENTION

[0011] The preferred embodiment of the invention presents a novel wearable hydration system that combines the functions of a backpack or lumbar pack with a hydration bladder in a unibody design. This approach addresses several key challenges associated with prior art hydration systems, particularly for cyclists and triathletes who prioritize aerodynamics, weight reduction, and performance optimization.

[0012] The system's primary construction in the preferred embodiment consists of three main pieces: a rearward facing panel, a side and bottom piece, and a forward facing panel that rests against the user's back. This three-piece design enables a reduction in bulk at the top of the pack, enhancing its aerodynamic properties. The anatomically contoured shape ensures a better fit to the wearer's back, improving both comfort and aerodynamics.

[0013] Key aspects of various embodiments further comprise:

[0014] Increased water storage capacity of 2.8 liters, compared to competitors' 1.5 liters, while maintaining a similar overall footprint and reducing weight by approximately 2 ounces.

[0015] A center rib design, which disperses water movement and contributes to the anatomical contouring of the pack.

[0016] A water-tight zipper that facilitates a widened opening on the external surface of the bladder, allowing for direct and fast replenishment of fluid and eliminating the need for a separated internal bladder.

[0017] A hose configuration that runs under the arm during intended use, reducing the need for manual repositioning during use.

[0018] The system's structure is reinforced with rigid eyelets in the side and shoulder pieces, which extend slightly from the body, providing stability and integrity to the pack's form.

[0019] A lumbar or configuration, offering additional versatility in how users can wear and utilize the system.

[0020] Auxiliary pockets attached to the front portion of the bladder for additional compartmentalized storage.

[0021] A unibody design that eliminates the need for separate bladder and pack components; reducing redundant materials; challenges associated with swapping, accessing and refilling a separate bladder unit; and allowing for a more streamlined and aerodynamic profile.

[0022] The system in an embodiment also acts as a heat sink, helping to regulate the wearer's temperature in part due to reduced layers and the choice of materials used in the construction of the unibody aspects, particularly the frontward facing panel, between the fluid and the user's back.

[0023] The materials used for the bladder construction, which primarily comprises the frontward facing panel, the rearward facing panel, and the side and bottom panel in the preferred embodiment, primarily comprise thermoplastic polyurethane (TPU). In various other embodiments, the materials used for the bladder construction comprise any of mylar, polyurethane, polyethylene, laminated polyurethane, and laminated polyethylene. The present inventor has observed the suitability of such materials in the context of the invention due to their durability, flexibility, ability to transfer heat, and water-resistant properties.

[0024] By integrating these features into a cohesive design, embodiments of invention address multiple challenges associated with prior art hydration systems. The preferred embodiment offers improved aerodynamics, increased capacity, easier access for refilling, better weight distribution, and enhanced user comfort, all while potentially reducing manufacturing costs and allowing for competitive pricing in the hydration market.BRIEF DESCRIPTION OF FIGURES

[0036] The preferred embodiment of the invention comprises a hydration system that integrates multiple components into a unibody design, addressing key challenges associated with prior art hydration solutions. This system comprises a bladder that serves as the pack itself, eliminating the need for separate bladder and pack components.

[0037] The unibody design in accordance with the preferred embodiment, as shown in FIG. 1, allows for a more streamlined and aerodynamic profile 110, as shown by FIG. 7A, in sharp contrast to the aerodynamic profile of prior art systems 120 an example of which is shown in FIG. 7B, which is particularly beneficial for cyclists and triathletes who prioritize reduced drag and improved performance. The system's construction in an exemplary embodiment consists of three main pieces to accomplish the unibody design: a rearward facing panel 200, a side and bottom piece 500, and a forward facing panel 300 that rests against the user's back during an intended use. This three-piece design enables a reduction in bulk at the top of the pack, further enhancing its aerodynamic properties. The anatomically contoured shape of the pack further ensures in accordance with the preferred embodiment a better fit to the wearer's back, improving both comfort and aerodynamics.

[0038] The three-piece construction allows for efficient material use while maintaining strength and durability in accordance with the preferred embodiment. The three-piece design comprises a strategic distribution of materials, minimizing excess while ensuring structural integrity. By such construction, the preferred embodiment achieves a balance between material efficiency and performance. The rearward facing panel 200 is designed to provide aerodynamic benefits, reducing drag during use. The side and bottom piece 500 in the preferred embodiment is adhered to and connects the rearward facing panel 200 and forward facing panel 300, creating the overall shape of the pack and notably defines watertight bladder while using materials efficiently. The forward-facing panel 300 is engineered to contour to the user's back, enhancing comfort and stability without unnecessary bulk. This optimized construction allows for the incorporation of key features without compromising the pack's strength or durability. For example, the design accommodates the internal rib 230, which contributes to the pack's shape stability and helps prevent water sloshing, without requiring additional reinforcing materials. The efficient use of materials in the three-piece construction contributes to the overall weight reduction of the system, making it approximately 2 oz. lighter than competing products. This weight savings is achieved while simultaneously increasing the water storage capacity to 2.8 liters, demonstrating the effectiveness of the optimized design.

[0039] A key feature of the preferred embodiment is the increased water storage capacity of the bladder, holding 2.8 liters compared to competitors' 1.5 liters, while maintaining a similar overall footprint. This increased capacity in the preferred embodiment is achieved without compromising the pack's aerodynamic profile or adding significant weight. In accordance with the preferred configuration, the system is approximately 2 oz. lighter than prior art products.

[0040] To address the challenge of fluid sloshing during use an exemplary embodiment incorporates a center rib design inspired by fuel transport vehicles. This internal center rib 230 not only disperses water movement but also contributes to the anatomical contouring of the pack, preventing bulging and maintaining the desired shape during use.

[0041] The preferred embodiment features a water-tight zipper 220, which when opened provides an opening 225 on the external surface of the rearward facing panel 200 comprising an outer surface of the bladder, allowing for direct and fast replenishment of fluid without the need to remove or replace the entire bladder. This design significantly improves accessibility and reduces refill times, addressing a major pain point in competitive environments where quick hydration is crucial.

[0042] The preferred embodiment further comprises a specially configured hose 400. Unlike traditional over-the-shoulder placements, as shown in FIG. 6B, the hose 400 is designed to run under the arm, as shown in FIG. 6A, reducing the need for manual repositioning during use. This configuration is particularly advantageous for cyclists, as it allows for drinking without removing hands from the handlebars. The hose 400 is secured near the center of the chest at a retention point 410, as shown in FIG. 6A, using either a magnetic element or a clip for easy detachment and use.

[0043] Additionally, the preferred embodiment acts as a heat sink, helping to regulate the wearer's temperature. This feature is made possible by the reduced layers, and the heat transferring characteristics of the materials chosen for construction in the layers and more particularly the forward facing panel 300 which is placed proximally to the wearer's back during the intended use as shown in an example in FIG. 7A, in association with the preferred embodiment.

[0044] The pack's structure in an exemplary embodiment is reinforced with rigid eyelets 320 as shown in FIG. 5C in the side and shoulder pieces of the frontward facing panel 300 and / or the rearward facing panel 200, which extend slightly from the body. These eyelets 320 provide stability and integrity to the pack's form, helping to maintain its aerodynamic shape when worn.

[0045] The preferred embodiment of the invention comprises a unibody design that integrates the hydration bladder comprising the rearward facing panel 200, the forward facing panel 300 and the side and bottom panel 500 into a pack-like unibody form, resulting in a more streamlined and aerodynamic profile. This design is particularly advantageous for cyclists and triathletes who prioritize reduced drag and improved performance.

[0046] The construction of the unibody design in the preferred embodiment primarily comprises three main pieces: a rearward facing panel 200, a side and bottom piece, and a forward facing panel 300 that rests against the user's back during intended use. This three-piece construction enables a reduction in bulk at the top of the pack, further enhancing its aerodynamic properties. The orientation of these three pieces allows for an anatomical fit that contours to the wearer's back.

[0047] In an exemplary embodiment, the rearward facing panel 200, the forward facing panel 300, or both each comprise a transparent or translucent window to allow for direct visual observation of the fluid level contained within the bladder. Each such window, optionally comprising a rearward facing panel window 210, as shown in FIG. 1, and frontward facing panel window 310 as depicted in FIG. 5C, is integrated into the unibody design of the watertight bladder, which is formed by the rearward facing panel 200, forward facing panel 300, and side and bottom panel 500 connected together in the preferred embodiment.

[0048] Such windows in an embodiment are constructed using a clear, flexible material that is compatible with the welding process used to create the watertight bladder, such as a transparent thermoplastic polyurethane (TPU) or a similar food-grade plastic. In an embodiment, this material is welded or bonded to the surrounding panel material using radio frequency (RF) welding or an alternative heat welding process, ensuring a watertight seal while maintaining visibility.

[0049] To enable this window aspect, the manufacturing process in an embodiment comprises the step of cutting an appropriately sized and shaped opening in the selected panel(s) during the initial fabrication stage. The transparent window material is then precisely positioned over this opening and securely bonded to the panel using the chosen welding technique. In accordance with various embodiments, the size and placement of the window can be optimized to provide clear visibility of the fluid level without compromising the structural integrity or aerodynamic properties of the hydration system.

[0050] This visual fluid level indicator provided by such windows in an embodiment addresses the challenge of monitoring fluid levels present within hydration packs, which has been an unsolved issue with prior art designs. By allowing users to quickly and easily assess the remaining fluid volume without opening the pack or removing it, this feature enhances the overall functionality and user experience of the system particularly in competitive or endurance sports scenarios where efficient hydration management is crucial.

[0051] The preferred embodiment of the invention incorporates specific materials for the construction of the watertight bladder, which comprises the rearward facing panel 200, side and bottom piece, and forward facing panel 300 that together define the exterior aspect of the bladder in a unibody design. The materials used for the bladder construction in various embodiments comprise any of thermoplastic polyurethane, mylar, polyurethane, polyethylene, laminated polyurethane, and laminated polyethylene. These materials are chosen for their durability, flexibility, heat transferring, and water-resistant properties, which are essential for the functionality of the hydration system in various aspects. In the context particularly of the rearward facing panel 200, which forms the outermost surface of the pack, such materials are observed to provide optimal aerodynamic properties and durability. The side and bottom piece, connecting the rearward facing panel 200 and forward facing panel 300, is likewise constructed from such materials in an embodiment which offer flexibility while maintaining structural integrity. The forward facing panel 300, which rests against the user's back during intended use, is in an embodiment likewise constructed using such materials which are observed to provide comfort and conform to the user's body shape.

[0052] The rearward facing panel 200 forms the outermost surface of the pack, designed to minimize air resistance during use. The side and bottom piece connects the rearward facing panel 200 and forward facing panel 300, providing structure and defining the pack's overall shape. The forward facing panel 300 is specifically engineered to rest comfortably against the user's back, ensuring a snug and stable fit during various activities.

[0053] The anatomically contoured shape of the pack is a key feature of the preferred embodiment. This design ensures a better fit to the wearer's back, improving both comfort and aerodynamics. The contoured shape is achieved in the preferred embodiment through the careful shaping of each of the three main pieces, particularly the forward facing panel 300. This panel is designed to follow the natural curvature of the human back, reducing air pockets and minimizing movement during use.

[0054] The reduction of bulk at the top of the pack is accomplished through the strategic placement of seams and the shaping of the three main pieces. By minimizing excess material and optimizing the pack's profile, the design reduces the frontal area exposed to airflow, thereby decreasing drag as demonstrated by FIG. 7A. This feature is particularly beneficial for cyclists and triathletes who maintain a forward-leaning posture during competition.

[0055] The unibody design also allows for the integration of internal structures, such as the center rib, which contributes to the overall shape and stability of the pack. This internal rib 230 helps maintain the pack's aerodynamic profile even as the fluid level changes during use.

[0056] By combining these design elements—the three-piece construction, anatomical contouring, the center rib 230 and strategic bulk reduction—the preferred embodiment achieves a hydration system that not only improves aerodynamics but also enhances user comfort. This integrated approach addresses key challenges associated with prior art hydration systems, particularly in high-performance athletic contexts where every aerodynamic advantage can contribute to improved performance.

[0057] The preferred embodiment of the invention features a significantly increased water storage capacity of 2.8 liters, which is nearly double the capacity of prior art devices that typically hold 1.5 liters. This substantial increase in fluid volume is achieved while maintaining a similar overall footprint to existing hydration packs, demonstrating a remarkable improvement in space efficiency.

[0058] The design of the preferred embodiment allows for this increased capacity without compromising the pack's aerodynamic profile. This is accomplished through careful engineering of the pack's shape and internal structure. The three-piece construction, consisting in an embodiment of a rearward facing panel 200, a side and bottom piece, and a forward facing panel 300, enables a more efficient use of space within the pack. The anatomically contoured shape further contributes to maximizing internal volume while maintaining a streamlined external profile.

[0059] A key feature that enables the increased capacity without sacrificing aerodynamics is the center rib design. Similar in one aspect to how fluid-containing semi-trucks utilize baffles, this internal rib 230 helps maintain the pack's shape and prevents bulging, even when filled to its full 2.8-liter capacity. This design element is crucial in preserving the pack's aerodynamic properties while accommodating the increased fluid volume. Despite the significant increase in capacity, the preferred embodiment achieves a reduction in overall weight compared to prior art products. Specifically, the system is approximately 2 ounces lighter than competing hydration packs.

[0060] The preferred embodiment of the invention features a unibody design that integrates the hydration bladder and pack into a single cohesive unit. This approach eliminates the need for a separate bladder and pack, which is a common configuration in prior art hydration systems. By combining these traditionally distinct components in association with prior art devices, the unibody design significantly reduces redundant materials that would otherwise be required for the individual construction of a bladder and a pack.

[0061] The integration of the bladder and pack into a single unit allows for a more efficient use of materials and space. The three-piece construction, in an embodiment comprising a rearward facing panel 200, a side and bottom piece, and a forward facing panel 300, enables the creation of a streamlined form that serves both as the fluid container and the wearable pack. This design eliminates the need for additional fabric layers, internal compartments, and attachment points that would typically be required to house a separate bladder within a pack. The reduction of fabric layers in particular enables the preferred embodiment to serve as a heat sink to allow the device to help regulate temperature of the wearer.

[0062] The reduction in redundant materials not only contributes to the overall weight savings of the system but also allows for a more aerodynamic profile. Without the need to accommodate a separate bladder, the pack's shape can be optimized for reduced drag and improved fit against the user's back. Additionally, the unibody design enables the incorporation of features such as the center rib 230 and rigid eyelets 320 directly into the pack's structure, further enhancing its functionality without adding unnecessary bulk or weight in accordance with the overall system.

[0063] The three-piece construction allows for efficient material use while maintaining strength and durability in accordance with the preferred embodiment. The three-piece design comprises a strategic distribution of materials, minimizing excess while ensuring structural integrity. By carefully engineering each component in the preferred embodiment, the invention achieves a balance between material efficiency and performance.

[0064] The rearward facing panel 200 is designed to provide aerodynamic benefits in accordance with the preferred embodiment, reducing drag during use. The side and bottom piece connects the rearward and forward panels, creating the overall shape of the pack while using materials efficiently. The forward-facing panel is engineered to contour to the user's back, enhancing comfort and stability without unnecessary bulk. This optimized construction allows for the incorporation of key features without compromising the pack's strength or durability. For example, the design accommodates the internal rib, which contributes to the pack's shape stability and helps prevent water sloshing, without requiring additional reinforcing materials. The efficient use of materials in the three-piece construction contributes to the overall weight reduction of the system, making it approximately 2 oz. lighter than competing products. This weight savings is achieved while simultaneously increasing the water storage capacity to 2.8 liters, demonstrating the effectiveness of the optimized design.

[0065] The preferred embodiment of the invention comprises an anatomically contoured design specifically engineered to fit the wearer's back, enhancing both comfort and aerodynamics. In such embodiment, the forward facing panel 300 is configured to generally follow the natural curvature of the human back, providing a snug and comfortable fit. This anatomical contouring is made possible by the unibody construction, which allows for precise shaping of the pack's form without the constraints of accommodating a separate internal bladder. The anatomical fit is particularly beneficial for improving aerodynamics, a critical consideration for cyclists and triathletes. By closely following the contours of the wearer's back, the pack minimizes air resistance and reduces drag.

[0066] The contoured design is further enhanced by the internal center rib 230, which not only helps control fluid movement but also contributes to maintaining the pack's shape. This rib 230 prevents the forward facing panel 300 and rearward facing panel 200 from bulging outwards, ensuring that the pack maintains its intended anatomical shape even when filled to capacity.

[0067] The contoured design also contributes to the pack's stability during use. By conforming closely to the wearer's back, the pack experiences less movement and shifting during high-intensity activities. This stability not only enhances comfort but also maintains the aerodynamic benefits of the design throughout use.

[0068] To achieve this anatomical fit, the pack's construction involves careful consideration of human body measurements and ergonomics. The curvature of the forward facing panel 300 is designed in an embodiment to accommodate the natural S-curve of the spine, with additional contouring to fit around the shoulder blades and lower back.

[0069] The side and bottom piece of the pack is engineered to create a smooth transition between the forward facing panel 300 and rearward facing panel 200, ensuring that there are no abrupt edges or protrusions that could compromise comfort or aerodynamics. This piece also allows for the incorporation of rigid eyelets 320, which contribute to the overall structural integrity of the pack without adding unnecessary bulk.

[0070] The anatomically contoured design addresses a key problem associated with prior art hydration packs, where the profile of the bladder is not anatomically contoured to the contours of a wearer's back. By integrating the bladder into the pack's structure, the invention allows for a more precise and comfortable fit that enhances both user experience and performance.

[0071] An embodiment of the invention includes the option for auxiliary pockets attached to an aspect of the rearward facing panel 200, providing additional compartmentalized storage for the user. These pockets enhance the versatility of the wearable hydration reservoir by offering secure and water-resistant storage for items such as keys, phones, or energy bars. The pockets are designed to be attached to the front surface of the watertight bladder, potentially using methods such as bonding with epoxy or glue to ensure a watertight seal. In an exemplary embodiment, the pockets comprise small hooks to hook to either side of the pack system comprising the watertight bladder. To facilitate easy access to stored items, the pockets optionally incorporate one or more zippers.

[0072] The preferred embodiment of the invention further comprises rigid eyelets 320 in the side and shoulder pieces of the hydration pack. This design feature serves multiple important functions while minimizing the need for additional mass in the main body of the pack. The rigid eyelets extend slightly from the body of the pack, providing structural support and integrity to the overall form. By incorporating these rigid elements, the design maintains its intended shape and aerodynamic profile during use, which is crucial for athletes seeking optimal performance. The use of rigid eyelets allows for a reduction in material elsewhere in the pack's construction. By providing localized structural support, these eyelets eliminate the need for additional reinforcing materials throughout the main body of the pack. This targeted approach to structural integrity contributes to the overall weight reduction of the system, which is approximately 2 ounces lighter than competing products.

[0073] Furthermore, the rigid eyelets 320 play a role in the pack's stability when worn. They help prevent buckling and maintain the desired form of the pack, which is essential for preserving its aerodynamic properties. This stability is particularly important for cyclists and triathletes who rely on consistent equipment performance during competition.

[0074] The combination of increased capacity and reduced weight in accordance with the preferred embodiment addresses two critical concerns for athletes: the need for sufficient hydration during long events and the desire to minimize equipment weight for optimal performance. The ability to achieve these improvements while maintaining a similar overall footprint to existing products is particularly noteworthy. This feature ensures that the preferred embodiment optimizes pack size and fit, while offering significantly enhanced functionality.

[0075] The preferred embodiment of the invention further comprises a center rib design to address the challenge of fluid sloshing during use. The internal center rib 230 serves multiple functions within the hydration pack. It acts as a barrier within the fluid compartment, effectively breaking up large waves of water movement that can occur during dynamic activities such as running or cycling. By dividing the fluid volume, the rib 230 reduces the momentum of water sloshing, thereby enhancing the overall stability of the pack during use.

[0076] Beyond its primary function of controlling fluid movement, the center rib 230 contributes significantly to the anatomical contouring of the pack. It helps maintain the desired shape of the forward-facing panel, ensuring that it follows the natural curvature of the user's back. This feature enhances comfort and improves the pack's fit during extended periods of wear.

[0077] The center rib 230 plays a crucial role in preventing bulging, which is a common issue with traditional hydration bladders. By providing internal structure and support, the rib 230 helps maintain the pack's intended shape even when filled to its full 2.8-liter capacity, in part by preventing an excessive rearward expansion of the pack by serving as a connective member between the rearward facing panel 200 and the forward facing panel 300 in a medial aspect of the system. This is particularly important for preserving the pack's aerodynamic profile, which is a key consideration for cyclists and triathletes.

[0078] During use, especially in high-intensity activities, the center rib 230 helps the pack maintain its desired shape. This is crucial for ensuring consistent weight distribution across the user's back, enhancing comfort and reducing fatigue. It preserves the pack's aerodynamic properties by preventing deformation that could increase drag. Additionally, it maintains the intended fit of the pack, reducing movement and potential chafing during extended use.

[0079] The center rib 230 in an exemplary embodiment is connected to the rearward facing panel 200 and forward facing panel 300 of the three-piece construction of the pack, working in harmony with the rearward facing panel 200, side and bottom piece, and forward facing panel 300. Its design and placement are carefully engineered to provide optimal performance without adding unnecessary weight or bulk to the system. In an exemplary embodiment, the center rib 230 extends vertically along the interior of the pack, spanning from the top to the bottom. The width of the rib 230 is approximately 2 inches in an exemplary embodiment. These dimensions are optimized to provide effective fluid control without significantly reducing the pack's overall capacity.

[0080] The center rib 230 is constructed in an embodiment from a lightweight, durable material such as thermoplastic polyurethane (TPU), high-density polyethylene (HDPE) or a similar food-grade plastic. This material choice ensures that the rib 230 is strong enough to withstand the forces exerted by the fluid during movement, while also being compatible with the contents of the hydration pack.

[0081] The attachment of the center rib 230 to the interior aspects of the forward facing panel 300 and the rearward facing panel 200 is achieved in the preferred embodiment through radio frequency (RF) welding. This process involves using high-frequency electromagnetic fields to create heat and fuse the materials together, creating a strong and watertight seal between the center rib 230 and the rearward facing panel 200 and the frontward facing panel 300. The RF welding process allows for precise control and efficient bonding of the thermoplastic materials comprising the construction of the watertight bladder in an embodiment.

[0082] In an alternative embodiment, the attachment of the center rib 230 may be achieved through a combination of heat welding and adhesive bonding. In this process, the edges of the rib 230 are first heat welded to create a watertight seal with the panels. This involves carefully applying heat to melt the edges of the rib 230 and the corresponding areas on the panels, fusing them together. After the heat welding in an exemplary embodiment, a food-grade adhesive is applied along the length of the connections to reinforce the bond and ensure long-term durability.

[0083] Both RF welding and heat welding processes are commonly used in the production of waterproof bags and hydration systems, with each method offering specific advantages in the context of embodiments of the invention.

[0084] The preferred embodiment of the invention features a water-tight zipper 220, which when opened provide an opening 225 on the external surface of the bladder, allowing for direct and fast replenishment of fluid without the need to remove or replace the entire bladder. This design in accordance with the preferred embodiment addresses a significant challenge associated with prior art hydration systems, particularly in competitive environments where quick hydration is crucial. In accordance with the preferred embodiment, the water-tight zipper 220 is positioned on the external surface of the pack, optionally integrated into an upper aspect of the rearward facing panel 200 in an embodiment, providing easy access to the bladder's interior. This placement eliminates the need to open multiple compartments or remove the bladder from the pack, as is often required with traditional hydration systems.

[0085] The zipper 220 in the preferred embodiment is constructed using high-quality, water-resistant materials specifically designed for outdoor and waterproof applications. An example of a suitable zipper configuration is the YKK Aquaseal® zipper, which features a polyurethane (PU) coating on the zipper tape and a specially designed interlocking tooth structure, which is incorporated in the configuration of an exemplary embodiment.

[0086] The zipper teeth in an exemplary embodiment are engineered to create a watertight seal when closed. Each tooth is precision-molded with a unique shape that allows for tight interlocking. When the zipper 220 is closed, these teeth form a continuous barrier against water ingress. The teeth are typically made from a durable polymer such as polyoxymethylene (POM) or polyethylene (PE), chosen for their strength, wear resistance, and low friction properties.

[0087] To enhance the water-resistant properties, aspects of the zipper 220 are coated with a waterproof material, often polyurethane or silicone. This coating extends beyond the teeth, creating a secondary seal when the zipper is closed. The zipper pull in accordance with various embodiments is designed to be easily graspable, even with wet or gloved hands, facilitating quick opening and closing during athletic activities. In an exemplary embodiment, the zipper pull comprises a large loop or textured surface for improved grip.

[0088] When the zipper 220 is opened, the aperture 225 widens to allow for easy access to the bladder interior. The zipper 220 is strategically placed to maximize the opening 225 size when fully unzipped. For example, the zipper 220 in accordance in various embodiments may run in a U-shape or J-shape along the top and partially down one side of the pack. This configuration allows the top portion of the pack to open wide, creating a large aperture for quick and efficient fluid replenishment. In an embodiment, the zipper 220 is incorporated in a straight line configuration to minimize challenges associated with manufacturability.

[0089] To further enhance water resistance and improve aerodynamics in accordance with an exemplary embodiment, a protective flap is incorporated over the zipper 220. This flap is constructed from the same water-resistant material as the pack's exterior and is designed to cover the entire length of the zipper 220. The flap may be secured in place using hook-and-loop fasteners (e.g., Velcro®) or snap buttons along its edge.

[0090] When opening the pack for refilling during an exemplary method of use, the user first releases the flap (e.g., by pulling apart the hook-and-loop fasteners), then unzips the zipper 220. As the zipper 220 is opened, the flap and the top portion of the pack can be folded back, revealing a wide aperture 225 for easy access to the bladder. This design allows for quick “dump in the water” refills during races or other high-intensity activities, addressing the need for fast fluid replenishment in competitive environments. To facilitate fast fluid replenishment, the zipper opening 225 in an exemplary embodiment is designed to be sufficiently wide, allowing for the easy pouring of water or other hydration fluids directly into the bladder. This design consideration is particularly beneficial in competitive scenarios, where minimizing refill time is critical. The direct access provided by the water-tight zipper 220 also simplifies the process of cleaning and maintaining the bladder. In accordance with an exemplary use, the wide opening 225 facilitates the ability for a user to easily reach inside to clean the interior surfaces or add cleaning tablets, enhancing the overall hygiene and longevity of the hydration system.

[0091] The water-tight zipper design of the preferred embodiment not only facilitates quick fluid replenishment but also enables the easy integration and replacement of an in-line water filter without the need to remove the entire bladder. The zipper's 220 strategic placement and wide opening 225 allow direct access to the bladder's interior,

[0092] The water-tight zipper design of the preferred embodiment not only facilitates quick fluid replenishment but also enables the easy integration and replacement of an in-line water filter without the need to remove the entire bladder. The filter is attached to the outside of the pack between the drinking hose and the drinking tube attachment port in accordance with the preferred embodiment. This external placement of the filter in the context of the preferred embodiment allows users to easily attach or detach it from the hose connection point without needing to access the interior of the pack. This feature significantly improves the maintainability and versatility of the hydration system, allowing users to adapt the pack to various water quality conditions without compromising the unibody design or requiring complex disassembly procedures.

[0093] The external filter placement, combined with the water-tight zipper for easy bladder access, provides a more comprehensive solution for both refilling and filtering water in accordance with the preferred embodiment. This design enhances the overall functionality and user-friendliness of the hydration system, particularly in competitive or outdoor environments where quick and efficient water management is crucial.

[0094] The preferred embodiment of the invention incorporates shoulder straps, a chest strap, and specific attachment methods for shoulder straps using oval grommets, which are integrally formed with or attached to appropriate locations on the main body of the pack which comprises a watertight bladder for retention of fluid, forming the interior volume of the unibody design. This design feature in an embodiment enhances the structural integrity of the wearable hydration reservoir while maintaining its unibody construction.

[0095] The attachment system comprises oval grommets strategically positioned on the watertight bladder. An exemplary embodiment comprises the following configuration:

[0096] A first oval grommet attached to the top portion near the first side of the watertight bladder.

[0097] A second oval grommet attached to the first side near the bottom portion of the watertight bladder.

[0098] A third oval grommet attached to the second side near the bottom portion of the watertight bladder.

[0099] A fourth oval grommet attached to the first side near the bottom portion, below the second oval grommet.

[0100] These oval grommets in accordance with an embodiment serve as secure attachment points for the shoulder straps.

[0101] The oval grommets are fabricated from materials chosen from plastic, rubber, or metal, providing durability and strength to the attachment points. They are securely fastened to the watertight bladder using chemical bonding or mechanical attachment methods, ensuring a robust connection between the straps and the bladder.

[0102] This grommet-based attachment system allows for easy assembly and disassembly of the shoulder straps, facilitating maintenance and customization of the wearable hydration reservoir. The oval shape of the grommets provides a larger surface area for attachment, distributing the load more evenly and enhancing overall comfort and stability during use.

[0103] The integration of these attachment points directly into the bladder's structure contributes to the unibody design of the wearable hydration reservoir, eliminating the need for separate attachment components and reducing overall weight and complexity in accordance with the preferred embodiment.

[0104] The preferred embodiment of the invention features an improved hose 400 configured with under-arm placement, addressing key challenges associated with prior art hydration systems. This design in the context of the preferred embodiment reduces the need for manual repositioning of the hose 400 during use, enhancing user convenience and performance, particularly for cyclists and triathletes.

[0105] In contrast to traditional over-the-shoulder hose configurations, such as shown in FIG. 6B, the preferred embodiment routes the hose 400 under the user's arm in accordance with the preferred embodiment and as shown in FIG. 6A. The under-arm configuration allows for easier access to the drinking tube without the need for manual repositioning. This configuration is particularly beneficial for cyclists, who can reach down with their face to drink without removing their hands from the handlebars.

[0106] In various embodiments, the hose 400 is supported by a magnetic element or clip placed near the center of the chest 410, optionally upon a chest strap extending between and connecting the two shoulder straps, allowing for easy detachment and reattachment during use. An exemplary embodiment includes a slider piece that clips onto the chest strap extending between and connecting the shoulder straps. This design ensures that the hose 400 remains secure and accessible throughout various activities.

[0107] The under-arm placement in accordance with an embodiment improves the overall aerodynamics of the hydration system. By eliminating the need for a hose 400 running over the back or shoulder, the design reduces drag and enhances the user's aerodynamic profile. This feature is particularly important for cyclists and triathletes, who prioritize aerodynamic efficiency in their equipment choices.

[0108] The improved hose 400 configuration also addresses the challenge of hose orientation present in prior art designs. Traditional hydration packs often require users to manually reposition the hose for drinking, which can be problematic, especially while riding a road bike. The under-arm placement minimizes this issue, allowing for more efficient hydration during high-intensity activities.

[0109] An embodiment of the invention features a strategic placement of the hose 400 attachment near the bottom of the front portion or on the bottom of the watertight bladder, as shown by FIG. 5B. In the preferred embodiment, the hose connection point on the bladder is positioned lower on the pack, allowing for a natural flow path under the arm. This positioning is designed to optimize fluid flow and user accessibility. By locating the drinking tube attachment in the lower region of the bladder, the invention ensures consistent liquid flow even when the bladder is not fully filled, as gravity assists in directing the fluid towards the outlet. This placement also contributes to the overall streamlined design of the hydration system, allowing for a more ergonomic routing of the hose 400 or drinking tube. The lower positioning of the attachment point facilitates the under-arm hose configuration, which is a key feature of the invention for improving aerodynamics and user convenience. Additionally, this placement helps maintain the bladder's shape and weight distribution when in use, further enhancing the pack's stability and comfort. The specific location of the hose 400 attachment point to the bladder in accordance with various embodiments, either near the bottom of the front portion or on the bottom of the bladder, allows for flexibility in design and manufacturing while maintaining the core benefits of the lower placement.

[0110] The hose's 400 material in accordance with various embodiments is flexible yet kink-resistant, ensuring consistent fluid flow even when bent around the user's torso. The length of the hose 400 is configured in various embodiments to provide easy access to the mouthpiece while minimizing excess material that could create drag or interfere with movement.

[0111] The mouthpiece at the end of the hose 400 is designed for easy operation with minimal effort, allowing users to hydrate quickly and efficiently during intense activities. This design consideration further reduces the need for manual repositioning and enhances the overall user experience.

[0112] An alternative embodiment of the invention comprises a configuration that allows the wearable hydration reservoir to be used as a sling with a single shoulder strap. This versatile design feature enhances the adaptability of the hydration system to different user preferences and situations. In this configuration, one of the shoulder straps, for example, the first shoulder strap, can be utilized as a sling strap. The large end of the strap is attached to the first attachment section at the top portion near the first side of the watertight bladder, while the small end is connected to the fourth attachment section on the second side near the bottom portion of the bladder. This diagonal attachment creates a cross-body sling configuration. Similarly, the second shoulder strap can be used to create a sling in the opposite direction. The unused shoulder strap in either configuration can be disconnected from the watertight bladder, further streamlining the sling design. This single-strap sling option provides users with a more casual and potentially less restrictive way to carry the hydration reservoir, which may be preferable for certain activities or shorter durations of use.

[0113] Various embodiments of the invention are available in at least different sizes to accommodate various user needs and body types. In exemplary embodiments, variations are provided corresponding to small, medium, and large configurations, each designed to fit different body types and hydration needs.

In an exemplary embodiment of a large size bladder, the bladder's dimensions are approximately 11.5″×9.5″×2″. The medium size in an embodiment offers a balance between capacity and compact design, capable of retaining approximately 2 liters of fluid. This size would cater to a wide range of users and activities, providing sufficient hydration for most endurance sports and outdoor activities. In an exemplary embodiment of a medium size bladder, the bladder's dimensions are approximately 11.5″×7″×2″. The small size in an exemplary embodiment comprises a capacity of approximately 1.5 liters. This compact version would be ideal for shorter activities or users who prefer a lighter, more minimalist hydration solution. In an exemplary embodiment of a small size bladder, the bladder's dimensions approximate 11.5″×5″×2″. In accordance with various embodiments, the main dimension that changes is the width of the bladder, while the height of the bladder and the depth of the bladder remain approximately of the same dimensions. which in one aspect preserves the maximum aerodynamic benefit among the various differentiated size configurations.

[0115] Across all sizes, the system in various embodiments maintains its key features such as the anatomically contoured design, the center rib 230 for stability, and the improved hose configuration. The overall footprint of each size is designed to be comparable to leading packs on the market, ensuring competitiveness while offering increased hydration capacity.

[0116] As such, the preferred embodiment of the invention presents a cost-effective design with significant potential for novel advantages including competitive pricing in the hydration market.
