A beverage filter or treatment bottle system has a bottle, lid, and a beverage improvement component such as a filter element. A filter element may be positioned to separate the interior space of the bottle into a filtered beverage compartment and an unfiltered beverage compartment. A tube passes through the filter into fluid communication with the filtered beverage compartment. The tube extends through the unfiltered beverage compartment to a nozzle in the lid of the bottle. A lid cover is fastenable onto the lid to enclose and close the nozzle. A filter cartridge may be provided. A UV sterilizer may be provided. An air bypass may be provided.

This disclosure includes a description of a public-surface contact-avoidance device comprising a container configured to store an item to be used repeatedly by a user; and a public contact device attached to the container; wherein the container is configured to be held by the user in a manner that allows the user to contact the public contact device with public surfaces without requiring the user to touch the public surfaces with the user's hands. In some embodiments, a liquid container comprises a bottle comprising a storage portion and a lid portion, the bottle being configured to store liquid for drinking; and a contact device affixed to the bottle; wherein the contact device is configured to be used to actuate a door without requiring contact between the door and the user's hands. In some embodiments, a method of actuating a device, such as a door or key pad, includes obtaining a liquid container with an integral public contact device; grasping the liquid container; and contacting the public contact device of the liquid container with the device to be actuated without requiring direct contact between the user's hands and the device to be actuated.

A replaceable container topper is disclosed. It is mainly combined with the cover of any container (clamshell cover or separate cover). The cover is configured with a first joint structure, and the topper is configured with a matching second joint structure at a corresponding position, so that the topper and the cover can be combined firmly and stably, and can also be separated easily and quickly; the topper can have various structural and functional designs with no limit to its shape and structure, including working as: any of a fixed or movable handle, a soft long suspender or short band, a decorator of any style, a small electronic device or mechanical device. Through various designs of the topper, the container as a whole can have unique and personalized styles to not only enhance the aesthetics but also provide additional practical functions, such as telling the time, playing music, emitting light, positioning and tracking, or even to provide value for collection.

A drinking vessel is provided with a nesting reservoir system for containing and dispensing metered amounts of liquid beverage enhancer. Multiple metered doses can be dispensed, with multiple refilling of the drinking vessel. The concentrated enhancer is metered by the rotation of a knob that rotates a plunger mechanism into a reservoir volume chamber, with one rotation being calibrated to deliver a single dosage of liquid enhancer. All parts can be easily removed, cleaned and then re-used.

A soft core bottle includes a bottle housing and a liner. The liner includes a first bottle opening and a first bottle body. The first bottle body is made of a soft material. The bottle housing is made of a hard material. The liner is attached to the bottle housing via the first bottle opening in an assembled state.

A wearable fluid reservoir configured to contain liquids includes a swinging suppressing mechanism to inhibit horizontal and vertical swinging of a reservoir main body in relation to a hydration pack in which the reservoir main body is inserted. The pack includes a connecting mechanism that mates with the swinging suppressing mechanism to form a detachable, yet secure fit between the reservoir and the pack. A sipping tube is coupled to the reservoir main body.

A portable beverage container includes a container body defining an interior volume adapted to store a liquid, and a handle assembly including a first handle portion movably coupled to a first exterior portion of the container body and a second handle portion movably coupled to a second exterior portion of the container body. The first and second handle portions are movably coupled to one another to move the handle assembly between an open configuration, in which the first and second handle portions extend away from the container body, and a collapsed configuration, in which the first and second handle portions are immediately adjacent the container body.
