A portable water-purifying pouch is provided that includes a pouch-shaped body comprising an inlet part, through which water to be treated is introduced, and an outlet part, from which drinking water obtained by filtering the water being treated is discharged and a pouch-shaped filter medium, which is provided inside the body so as to hold and filter the water being treated, which has been introduced into the body, and comprises a fiber web layer having the structure of a three-dimensional network formed of nanofibers. The portable water-purifying pouch allows a large flow rate of drinking water to be obtained in a short time while filtering, with significantly superior efficiency, foreign substances such as bacteria and harmful germs in the water being treated merely by self-weight or by lightly applying pressure with a hand to the water being treated.

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.

A portable water bottle includes a water bottle body having water stored therein; and a sterilizing module for irradiating the inside of the water bottle body with sterilizing ultraviolet rays. The sterilizing module further includes a housing having an ultraviolet outlet through which the sterilizing ultraviolet rays pass; a light source module for emitting the sterilizing ultraviolet rays; and a power storage member for supplying power to the light source module.

The present disclosure relates to a smart bottle and a method of controlling the same. The smart bottle includes a bottle for containing liquid and a base that is disposed under the bottle and includes an elastic body that is elastically deformed by the weight of the bottle and the base, a weight measurement sensor disposed above the elastic body and measuring the weight of the bottle by measuring a pressure that the elastic body transfers in a vertical direction from the ground as a reaction to gravity, and a controller that measures the amount of fed milk based on the change in the weight measured by the weight measurement sensor.

Multilayered electrolyte compositions and methods for their manufacture and use are described. The compositions can have an inner core and one or more coating layers. The compositions can contain at least one chlorine source and at least one citrate salt. The compositions are useful for treating water to improve safety, among other things.

A porous carbon material having a value of a specific surface area by a nitrogen BET method of 1×10.sup.2 m.sup.2/g or more, a volume of fine pores by a BJH method of 0.3 cm.sup.3/g or more, and a particle size of 75 μm or more, alternatively, a porous carbon material having a value of a specific surface area by a nitrogen BET method of 1×10.sup.2 m.sup.2/g or more, a total of volumes of fine pores having a diameter of from 1×10.sup.−9 m to 5×10.sup.−7 m, obtained by a non-localized density functional theory method, of 1.0 cm.sup.3/g or more, and a particle size of 75 μm or more.

A portable water bottle includes a water bottle body having water stored therein; and a sterilizing module for irradiating the inside of the water bottle body with sterilizing ultraviolet rays. The sterilizing module further includes a housing having an ultraviolet outlet through which the sterilizing ultraviolet rays pass; a light source module for emitting the sterilizing ultraviolet rays; and a power storage member for supplying power to the light source module.

The present invention relates to an electrochemical device for releasing ions, comprising an electrical circuit comprising a first electrode and a second electrode adapted for providing a galvanic cell when the electrodes are exposed to a fluid constituting an electrolyte, and a boost converter adapted for amplifying a potential generated between the first and the second electrode. The electrical circuit further comprises a third electrode connected with an output side of the boost converter, wherein the second and the third electrode constitutes an electrolytic cell powered by the galvanic cell when the electrodes are exposed to a fluid. The present invention further relates to devices, such as a toothbrush or a shaver, adapted for being used in connection with a fluid, comprising such electrochemical device for releasing ions.

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.

The invention relates to container bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such container bodies may have an undivided internal storage volume, so as to not include a reservoir compartment for unfiltered water. They may be part of systems configured to filter water both as water is introduced into a container body of the system and as water is poured from the container body of the system. The filter assembly may be attached to the container body at a location proximate the outlet of the system. Filter media of the filter assembly may comprise an activated carbon textile material that presents a curved surface to water passing through the filter assembly. The container body may be configured as a pitcher, carafe, water bottle, jug, or other shaped container.
