Embodiments relate to systems, devices, and methods for sanitizing stored contents. System includes main and secondary assemblies. Main assembly includes main opening and main storage section. Secondary assembly includes securing portion, radiation assembly, and control assembly. Securing portion transitions between secured and unsecured states. Secured state is when main and secondary assemblies are secured together. Radiation assembly is configured to emit radiation, and is formed symmetrically relative to a central axis. Control assembly includes first and second safety assemblies and control processor. First safety assembly is configured to determine whether the storage system is in the secured or unsecured state. Second safety assembly is configured to determine whether the secondary assembly is in a safe or unsafe orientation state. Control processor is configured to control the radiation assembly to emit radiation when the storage system is in the secured state and the secondary assembly is in the safe orientation state.

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 bottle for use with a system for mineralizing drinking water has a body and an inner cap fixedly positioned in the opening of the body. The body has a neck extending outwardly therefrom. The neck defines an opening at the upper end of the body. The inner cap has an upper surface affixed over the opening of the body. The inner cap has an annular portion extending downwardly from the upper surface. The annular surface bears against an inner wall of the neck of the body. The inner cap has a receptacle opening at the upper surface. The inner cap has a channel extending downwardly therefrom so as to open to the interior volume of the body. A straw extends through the channel and into the interior volume of the body so as to have an end position in proximity to the bottom of the body.

A handheld sanitizing device may include a housing with a first end and a second end. The housing may enclose a first cavity and a second cavity. A sanitizing light may be disposed at the first end of the housing. The sanitizing light may be configured to kill biological contaminants. A removable cap may attach to the first end and may cover the sanitizing light. An extendable agitator may extend from the first end of the housing and retract into the first cavity. A motor disposed in the first cavity may actuate the agitator. The agitator may be configured to stir a fluid. The housing may be configured to sit in a mouth of a container, extend into a reservoir of the container, and rest on the mouth of the container. A charging port may be disposed on the housing and electronically coupled to the motor and/or the sanitizing light.

Beverage filtration device including a lid body having an internal housing configured to hold an ion exchange resin-filed cartridge therein having a connection end and a top end having an opening therein, and, stem body having a cap region, collar, beverage conduit and stem air tube. The cap region couples to the connection end of the lid body to form a liquid-tight seal coupling there-between. A collar wall first portion fits inside a beverage mouth container and a second portion located outside of the mouth. The beverage conduit spans the collar, a first conduit opening open to the coupling between the cap region and the connection end and a second conduit open to a container interior. The stem body air tube extends through the collar, a proximal opening of the stem body air tube opens to an air vent hole located in the second portion of the collar wall, and, a distal opening of the stem body air tube opens to the container interior.

The present invention is a water purifier cartridge to be attached to a container including a water storage portion having an opening at an upper portion thereof, and a lid that has an outlet for discharging water stored in the water storage portion and is configured to close the opening of the water storage portion, the cartridge including: a support including a circumferential wall portion formed in a cylindrical shape and a closing portion that closes one end portion in an axial direction of the circumferential wall portion and in which an air hole is formed, another end portion in the axial direction being open; and a filter member that is supported by the support so as to extend along the circumferential wall portion.

A novel fibrous membrane comprises at least one substrate layer comprising at least 80% by weight of microfibers that carry positively charged and/or negatively charged functional groups, and at least one layer of filtration material attached to the substrate layer, wherein the layer of filtration material comprises at least 80% by weight of nanofibers that carry negatively charged and/or positively charged functional groups. The fibrous membrane is able to remove or reduce the concentration of bacteria, viruses and heavy metals while maintaining relatively high water flow. A filter comprising the fibrous membrane and a method for manufacturing the fibrous membrane are also provided.

A filtering container for liquids, in particular water, comprising a main body, a gripping portion which is configured to be gripped by a user for lifting the container and pouring the liquid contained therein out of it, a closure group of an opening which is defined in the main body and which includes a filtering element which is arranged in such a position as to intercept the liquid being discharged from the main body, dispensing means for the liquid which are configured in such a manner that the liquid is dispensed through a dispensing zone for the liquid defined adjacent to a side wall of the main body and a ventilation pipe which opens inside the main body in a ventilation zone and which extends in the form of an elongate element towards the interior of the main body.

The invention relates to a bioactive filter for the disinfection of liquids, in particular water or aqueous solutions in containers. A structure that is advantageous in terms of filter efficiency is obtained by forming a spherical or oval filter body (1), which is coated with noble metals (FIG. 1).
