20090294347 | Dispensing device - The invention relates to a dispensing device for a liquid medium, having a medium reservoir for accommodating the medium, having a dispensing opening for dispensing the medium from the medium reservoir, and having a pressure-equalizing channel which opens out into the medium reservoir and has a microbiologically active filter arrangement inserted therein. | 12-03-2009 |
20100320135 | WATER PURIFICATION KETTLE - A water purification kettle includes a kettle body forming a top open container. A top cover is coupled to the opening of the body and forms a stepped water replenishment hole, a water dispense hole, and a vent hole. A filter is fit into the body through the stepped water replenishment hole and retained in position by the water replenishment hole lid. The filter contains therein in sequence a layer of energy ceramic spheres, a layer of coconut shell activated carbon, a layer of calcium sulfite, and a filtering net. A water dispense knob is coupled to the water dispense hole and forms a water passage and a vent hole. By rotating the water dispense knob to have the water passage corresponding to the water dispense hole and the vent hole aligning each other, water is allowed to pour out from the kettle body. | 12-23-2010 |
20110005991 | CONTAINER FOR FILTERING LIQUID HAVING AN OUTLET APERTURE FOR AIR - A container for the filtration of liquid is described, which has a cup and a cover mounted on the cup. The cup is at least partly filled with a filter material and has at least one outlet window for the liquid. The cover has at least one inlet window and at least one outlet window for air, wherein at least the windows have lattice-like structures with lattice openings. The air outlet window has at least one recess extending inward from the plane of the window, which is provided at least partially with at least one lattice structure. | 01-13-2011 |
20120031830 | Transporting and Treating Water - Water can be transported and/or treated using a system or container in which a collapsible framework is attached to a membrane. A collapsible water container defining a volume for receiving, transporting, and delivering water can include: a membrane of material substantially impermeable to water, the membrane having a substantially cylindrical expanded configuration with a central axis and substantially contracted configuration; wherein the membrane configured to rotatably expand about the axis when water is placed within the volume defined by the collapsible water container and rotatably contract about the axis when water is removed from the volume defined by the collapsible water container. | 02-09-2012 |
20120055862 | FILTERING WATER BOTTLE - A portable, personal apparatus for treating drinking water comprises a generally tubular or cylindrical filter housing containing filtration media and water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter. The design of the apparatus involves the bottle exterior and interior contouring to the filter and enables the efficient and rapid gravity flow of water in through the filter. The apparatus may be configured such that water is first passed through a top reservoir designed to receive water, followed by a porous mesh, followed by granular filtration and antimicrobial media agitated by turbulent motion of influent water, followed by a porous mesh before reaching a durable and reusable water containment vessel. | 03-08-2012 |
20120217197 | END OF WATER PURIFICATION CARTRIDGE LIFE APPARATUS - End-of-life apparatus for use in water purification cartridges are disclosed. The apparatus includes a water-disintegrable tablet configured to disintegrate a predetermined amount after contacting a predetermined volume of water flow. The tablet prevents the stoppage of water until the tablet has been contacted by the predetermined amount of water. The various end-of-life apparatus use different means to stop the water flow when the tablet has disintegrated a predetermined amount. | 08-30-2012 |
20130334121 | WATER PURIFYING DEVICE - A water purification device includes a container, at least a filtration unit, and a trailing cable connected to the container or the filtration unit. The container has therein a chamber and at least a first opening in communication with the chamber. The filtration unit is disposed in the first opening to admit sewer water and thus remove most impurities therefrom. Accordingly, the water purification device sinks spontaneously into the sewer water to be filtered so as, to filter the external sewer water by means of water pressure and thus produce drinking water. | 12-19-2013 |
20150367269 | Method for Making a Filtering Element and Filtering Element - A method for making a filtering element from a film of non-woven material, the filtering element being associable with a container for containing and/or retaining a product, including hot pressing at least one defined portion of the film or of the filtering element so as to obtain a pressed portion in which fibres, in particular synthetic and/or plastic fibres, of at least one external surface layer of the non-woven material are compacted and pressed together and in which a thickness of the non-woven material is reduced by a percentage between 30 and 50%. | 12-24-2015 |
20160031720 | Roll-up water bottle with closure/filter assembly - 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. | 02-04-2016 |
20160031721 | GRAVITY-FED AND DUAL ION-EXCHANGE WATER FILTRATION BOTTLE - Systems, devices, and methods of filtering water utilize an integrated gravity-fed, dual ion-exchange filtration bottle. Flow-through multi-stage filtration technology is applied to a personal water bottle. The system filters water from an upper unfiltered water reservoir through a multi-stage filter to a lower filtered water reservoir. A user then drinks from the lower reservoir. The bottle includes a cap with a filtered water outlet through which filtered water in the lower reservoir is accessed with a straw, spout, or other access device. The cap includes an unfiltered water inlet to allow filling and refilling of the upper reservoir without disassembling the bottle. The bottle includes a filter vent that eliminates air locks and partial vacuum that can develop when unfiltered water drains from the upper reservoir through the filter to the lower reservoir. This gravity-fed dual ion-exchange filtration system allows for more complete removal of dissolved solids. | 02-04-2016 |
20160251234 | PORTABLE WATER BOTTLE ASSEMBLY HAVING A REPLACEABLE FILTER CARTRIDGE | 09-01-2016 |
210245000 | Attached variable flow controller | 1 |
20090101565 | Water-Cleaner - A portable direct current water-cleaner includes a handheld tank for storing a water chamber and a component chamber entirely therein. The water chamber is adapted for containing water and the component chamber for receiving a pump adapted for pumping the water, a filter adapted for filtering the water and a switch valve installed in the tank. The switch valve is operable between a first mode for directing the water from the pump to the filter so that the water passes through the filter and a second mode for bypassing the filter. | 04-23-2009 |
