[0001] This application claims the benefit under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application Ser. No. 63 / 706,458 entitled “Hydration System, Apparatus, Method of Making and Using the Same” filed October 11, 2024 and U.S. Provisional Application No. 63 / 842,489 entitled “Hydration System, Apparatus, Method Of Making And Using The Same” filed July 11, 2025, each of these applications are incorporated herein by reference as if fully set forth herein.FIELD OF INVENTION

[0002] The present disclosure relates to hydration systems, and more particularly to a hydration system with an adapter that enables widemouth bottles to interface with military- specified North Atlantic Treaty Organization (NATO), Nuclear, Biological, Chemical (NBC), and Chemical, Biological, Radiological, and Nuclear (CBRN) caps and other connection components configured for use with protective masks and respirators, where portions of the system may comprise materials exhibiting antibacterial, antifungal, or antimicrobial properties.BACKGROUND

[0003] Hydration systems have become increasingly important in various applications, particularly in military, emergency response, and outdoor recreational activities. Traditional hydration systems typically utilize narrow-mouth bottles or specialized hydration bladders that can be difficult to fill, clean, and maintain. Widemouth bottles offer advantages in terms of ease of filling and cleaning, but present challenges when attempting to integrate them with specialized drinking systems or protective equipment.

[0004] In military and emergency response scenarios, personnel often operate in environments where chemical, biological, radiological, or nuclear threats may be present. These situations require the use of protective masks or respirators that cover the face and mouth, making conventional drinking methods impractical. Specialized canteen caps and drinking systems have been developed to allow hydration while wearing such protective equipment, butPatentAtty. Docket No. 16766.0002.005 these systems are typically designed to work with specific bottle configurations and thread patterns.

[0005] The integration of widemouth bottles with existing military or emergency response hydration systems presents technical challenges related to thread compatibility, sealing, and flow control. Standard widemouth bottles commonly feature 63 mm thread outer diameters with specific thread pitches that are incompatible with military-specified NATO, NBC, and CBRN threading standards. These military standards typically employ 38 mm threading systems designed for rapid engagement and secure coupling under adverse conditions.

[0006] Additionally, maintaining proper hygiene and preventing contamination of drinking water during extended use periods remains a concern, particularly in field conditions where cleaning and sanitization opportunities may be limited. Current hydration systems may also lack adequate provisions for preventing bacterial, fungal, or microbial growth within the bottle material itself, which can lead to contamination issues and potential health risks during extended deployment or storage periods.

[0007] The development of adapter systems that can bridge the gap between commercial widemouth bottle standards and military hydration requirements represents an ongoing area of technological development in the hydration system field. Such systems would provide personnel with the flexibility to use readily available commercial bottles while maintaining compatibility with protective equipment and specialized caps designed for hazardous environments.SUMMARY
