Abstract: A closure element is adapted for use with a cup to form a container when combined, the container configured to hold a beverage or a granular substance. The closure element comprises a sealing portion and an annular sealing wall extending around the sealing portion, the annular sealing wall is tilted with an angle alpha of between 2-8 degrees in relation the axis A and intended to be in contact with an inside surface of an annular inner wall of the cup to seal the container. The closure element further comprises a spout configured to deliver the beverage or granular substance to a user. The closure element is configured to be pressed into the cup so that the annular sealing wall engages the inside surface of the annular inner wall of the cup to form a tight seal between the closure element and the cup.

Abstract: There is disclosed a container configured to hold a substance and extending along an axis A. The container comprises a container body configured to hold the substance. The container body comprises a top part. Further, the container body comprises a closure section arranged in an opposite end of the container body compared to the top part. The closure section comprises a first circular cross-section with a first radius in a plane transverse to the axis A. The closure section further comprises a second circular cross-section with a second radius in a plane transverse to the axis A, the second radius is larger than the first radius. The closure segment further comprises an annular wall extending from the second circular cross-section to the first circular cross-section such that the annular wall is formed with an angle alpha in relation to the axis A. The closure section is arranged so that the first circular cross-section is facing the top part.

Abstract: There is disclosed a container (100) configured to hold a fluid or granular substance and extending along an axis A. The container comprises a top part (110). The top part comprises a container body (120) configured to hold the fluid or granular substance, and a first opening (130) with a first area (A1). The container further comprises a bottom part (140) configured to be permanently fitted to the top part. The bottom part comprises a second resealable opening (150) with a second area (A2), the second area is larger than the first area. There is also disclosed a method for filling a container.

Abstract: A water container for purifying water. The water container includes an opening configured to receive water, a container body arranged to enclose the water and a water purifying unit configured to purify the water. The water purifying unit includes an at least partially transparent plate, which includes a coating of metal-oxide nanoparticles on a first side facing the container body, wherein the first side is configured to be in contact with the water, and an ultraviolet light module configured to radiate towards a second side of the at least partially transparent plate such that light from the ultraviolet light module at least partially passes through the at least partially transparent plate. Also, a method for purifying water within a water container.

Abstract: A system configured to deliver water in different purification states. A water valve selection unit to receive a purified water flow from a water purifier via a first valve and to receive an unpurified water flow from a water source via a second valve. The water valve selection unit to direct a water flow including one of the purified water and the unpurified water through an exit portion. A tap to receive the water flow from the exit portion, and to deliver the water flow to a user. A control unit to control the water valve selection unit to regulate a purification state of the flow. The control unit to inform the user of the purification state of the flow delivered by the tap. The water valve selection unit includes a measuring element to measure a volume of the flow that passes the exit portion.

Abstract: A method of purifying air for inhalation. The method includes the steps: use of an ionizing device, electrically charging airborne particles; outputting the charged airborne particles, and filtering air through a filter included in a respiratory mask worn by a user present, wherein the filter includes filter fibers of a material attracting at least some of the charged airborne particles. A related system for purifying air for inhalation is also provided.

Abstract: An improved method is disclosed for cleaning a flow of gaseous fluid, such as room air, from particles present in the fluid, the gaseous fluid being ionized, and using a conductive grid placed across and upstream of the filter for protecting the filter from being charged by free ions. An air purifier filter cartridge using the ion-intercepting grid of the invention is also disclosed. The grid may be connected to or electrically insulated from the ionizer ground potential, with equal effect.
