A “Wing-shaped” liquid bladder device is disclosed having angular shoulder wings on the left and right sides. The wings join at an angle creating a substantially “V-Shaped” hollow volume for storing liquids. A re-sealable opening receptacle can be found on top the bladder for filling the hollow volume. One or more additional arms can be added to the wings. The wings and arms meet at a lower distal end to create a substantially “V-shaped” funnel that is attached to an outlet pipe. In the front, shoulder straps are attached to the wings and they go over and across the front of the wearer's body to a lower portion of the arms of the bladder. The outlet pipe is attached to the funnel and extends up to the wearer's shoulder. A drinking straw can be attached to the outlet pipe to allow the user to easily access the liquids inside.

The invention relates to portable liquid supply device, mainly for water from central and other sources or for suspensions, for example pharmaceutical products and nutrient liquids. The invention can be used in household, outdoors, in the garden plots, in health care institutions, for example, for patients with dysphagia, as the source of purified drinking water or nutrient liquids, which go to a patient easily.

Liquid supply device, comprising raw liquid vessel, pressure generating means, liquid treating unit, comprising a lid, liquid supply means, liquid treating element and raw liquid inlet element, characterized in that is configured to supply treated liquid in portions from 1 to 600 ml, preferably from 5 to 100 ml, with velocity from 0.1 to 200 ml/seconds, preferable from 0.5 to 10 ml/sec.

A water sanitization cap for covering a bottle includes a barrel, a shell, and a waterproof compartment. The shell surrounds at least a portion of the barrel and includes an outer surface and an inner surface. The waterproof compartment is formed within the interior of the barrel. The waterproof compartment includes one wall formed at least in part from a transparent material, one or more light emitting diodes (“LEDS”), a sensor, and a filter cage. The LEDS are fixed within the waterproof compartment and oriented to shine light through the transparent material. The sensor includes an activation button. The sensor is configured to sense when the cap is in the installed position and supplies voltage to the activation button. The activation button is activated by a user in the installed position to supply voltage to the LEDS to emit light. The filter cage is operable to contain a filter.

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.

A system of filtering runoff water from a roof cleaning is used to remove contaminants from water that has been used for rooftop cleaning. The system is also configured to gather water noninvasively from downspouts or topographically low points upon the roof. The system of filtering runoff water from a roof cleaning utilizes a pump that is connected to a large bin for filtration. The pump is placed at a low point upon the rooftop, thus enabling optimal water collection for subsequent pumping. The bin contains a disposable filter through which pumped water may pass, either through force from the pump pressure or due to the effects of gravity. Clean water is then ejected from the bin, or otherwise guided to an appropriate drainage area. This arrangement allows for easy maintenance, as a rooftop cleaner need only to swap out the old filter for a new one after cleaning.

A plurality of caps are provided each with a visual coding of color and/or indicia for use with different sizes of bottles at least in accordance with a height of the bottles from a closed bottom end to an open top end for engaging each of the caps. Each of the caps has a tube mounted to, or through, an aperture extending through a top closed end of the cap to extend a selected length enabling one end of the tube to reach or extend along an interior surface of the bottom end of any of the bottles of the height to which the cap is coded for use therewith. The other end of tube is extendable to a bioreactor container. Each of the caps has another tube or port to another aperture of the cap to provide an air vent with an optional air filtering device.

The present invention is directed to a water container. The water container comprises a fluid path defined by a rigid fluid reservoir, a filter and a water outlet having an open position and a closed position; a fluid inlet, and a pump coupled to the fluid inlet. The pump comprises a non-return valve and a piston shaft through which a piston head may be moved, the piston head being coupled to a piston rod slidably moveable through an orifice at a first end of the piston shaft, wherein the orifice is sealed about the piston rod such that, in use, operation of the pump pumps fluid from a fluid source in communication with the fluid inlet, through the non-return valve and into the fluid reservoir so as to pressurise the fluid reservoir such that, when the water outlet is in the open position, a pressure differential induces a flow of water along the fluid path through the filter to the water outlet. The piston shaft is substantially surrounded by the filter.

An apparatus provides a water bottle mouthpiece attachment which can filter microplastics and other contaminant substances from bottles, particularly disposable plastic water bottles. The filter of the apparatus includes a filter housing that is attached to a cap that fits inside a common plastic bottle. Soft rubber rings, tapering from to radially larger on the top to radially smaller on the bottom in a generally conical fashion, ensure a watertight fit to the inside opening of any drinking bottle. A friction closing/opening spout at the top of the filter enables selective opening of the bottle and prevents accidental spillage of bottle contents. The filter housing is also offset from the center, giving space to an air valve that allows air to enter the bottle without disturbing the flow of water from the bottle, thus providing optimal lamellar flow without allowing fluid to escape through the air valve during consumption.

A personal hydration system is disclosed that includes a reservoir and a drinking hose. The drinking hose is in fluid communication with the reservoir and includes a textured (irregular) inner surface configuration to facilitate cleaning of the drinking hose.
