A method of forming a hybrid, hand-held drinking bottle includes connecting a top element to a bottom element to form a seam therebetween. The top element includes a top wall extending around a top axis, and a top opening extending within the top element between opposed ends of the top wall. The top element is formed from a material that is of a first hardness. The bottom element comprises an end wall, a bottom wall extending around a bottom axis, and a bottom opening extending between the end wall and an opposing end of the bottom wall. The bottom element is formed from a material that is of a second hardness less than the first hardness. The top opening is in communication with the bottom opening when the top element is connected to the bottom element. The method further includes over molding a collar around the seam.

Disinfection of a surface, such as a mouthpiece of a water bottle, using ultraviolet radiation is disclosed. A cover assembly can include a cover configured to selectively enclose the surface to be disinfected, such as the mouthpiece. The cover assembly can be configured such that ultraviolet radiation can be emitted into an interior volume at least partially formed by the cover and including the surface. The cover assembly can further include a power source which provides power to one or more ultraviolet light sources that emit the ultraviolet radiation. The cover assembly can be a mouthpiece cover assembly physically separate from a container and top cover or integrated in the top cover. A container and a top cover including one or more features for improved cleanliness are also disclosed.

An endoscope system and particularly but not exclusively a water bottle cap assembly for an endoscope/endoscopic device. An endoscope system includes an endoscope device and means for directing a fluid adjacent a tip of the endoscope device. The fluid directing means includes a fluid container for containing the fluid, the container including an inlet and an outlet. The system further includes separating means for separating liquid or solid particles from gas entering the container through the inlet.

A multi-functional apparatus for carrying liquid has a container having a solar panel, a battery, a lid for opening the container, a middle portion enclosing the container, and a bottom portion; wherein the solar panel charges the battery, which may be used for providing LED lighting or for charging electronic devices.

A bottle is provided that incorporates a free flow filter that can passively filter water by the action of gravity as a user drinks from the bottle. The bottle uses an umbrella valve to vent air from the filter into the body of the bottle so that a continuous stream of filtered water is provided by the bottle as water is poured from the bottle. In an embodiment, the umbrella valve moves from a closed position to an open position when at least a threshold pressure is applied to a diaphragm of the valve. When in the open position, air may vent from the filter and into the body of the bottle.

A storage bottle with filtration and disinfection effects has an outer casing, a cap, a bottom base, and a waterproof board. The outer casing is hollow. The cap is detachably connected to the outer casing and has an assembling recess and a filter group. The assembling recess communicates with the outer casing. The filter group is deposited in the assembling recess and has at least one filtering layer. The bottom base is detachably connected to the outer casing and has a mounting recess and a sterilization group. The sterilization group is deposited in the mounting recess and has at least one light emitting diode. The at least one light emitting diode emits an ultraviolet light with a sterilization band to liquid in the outer casing. The waterproof board is deposited between the outer casing and the bottom base to close the mounting recess of the bottom base.

A hydration system is provided. The hydration system includes a container configured to receive and maintain a quantity of liquid, a pump connected to the container, a hose system comprising a plurality of hoses connected to the container and the pump and configured to receive liquid from the container, and an end piece connected to one of the plurality of hoses configured to be used by a user of the hydration system. The pump is configured to circulate liquid through the hose system and container to maintain a relatively similar liquid temperature for all liquid contained in the hose system and container.

An apparatus for dispensing a liquid is disclosed. The apparatus can include a cap configured to connect to a container body having a chamber for containing the liquid. The cap can include a fill aperture through which the liquid is supplied to the container body and a pour aperture through which the liquid exits the apparatus. A fill lid can be rotatable about a pivot axis in a first direction to close the fill aperture and rotatable about the pivot axis in a second direction to open the fill aperture, the first direction opposite the second direction. A pour lid can be rotatable about the pivot axis in the first direction to open the pour aperture and rotatable about the pivot axis in the second direction to close the pour aperture. A filter assembly comprising a filter cartridge can connect to the cap.

An automatic water filtering purifying bottle relates to a technical field of water purification and includes a bottle body and a filter device. The bottle body includes a raw water cavity and a purified water cavity. The raw water cavity and the purified water cavity are sequentially disposed along an axis direction. The bottle body defines a raw water opening and a purified water opening. The raw water opening is capable of being opened and closed. The raw water opening is configured to communicate with the raw water cavity. The purified water opening is capable of being opened and closed. The purified water opening is configured to communicate with the purified water cavity. The filter device is configured to filter water in the raw water cavity and is communicated with the raw water cavity and the purified water cavity.

A roll-up water bottle comprises a hollow cylindrical opening adjacent one end thereof. The opening retains a removable closure/filter assembly. That assembly includes a filter retained within a bottle cap. The cap is positioned within a bottle opening support member retained within the hollow cylindrical opening. The filter housing is generally cylindrical but also includes an outer profile that includes a pair of opposed flat walls. When the filter is secured within the bottle cap and the cap secured within the bottle opening support member, a pair of water flow channels are created. Upon the user applying suction or pressure from squeezing the bottle, water contained with the bottle flows through vent openings in the filter, but also up through the water flow channels. The result is a more even distribution of fluid across a greater portion of the filter.
