An air purifying device has a housing, a blower assembly disposed within the housing for blowing air, an electrically-charged electrostatic plate, and a thermal layer for heating the air to a temperature of at least 75 degrees Celsius, and preferably at least 180 degrees Celsius. The electrostatic plate is connected to a high voltage power supply providing a voltage of at least 3 kilovolts and preferably at least 30 kilovolts. The blower assembly moves the air through the thermal layer at a volume of at least 0.25 cfm and preferably at a volume of less than 15 cfm.

A method for preparing a bactericidal film on fiber cloth, comprising cleansing a reel of fiber cloth; placing the reel of fiber cloth into a vacuum chamber; supplying a DC power and a mid-frequency power; introducing argon gas to increase the chamber pressure to 0.3 Pa; position sputtering targets in the following order: silicon target, silicon carbide target, silver target, silicon carbide target, silver target, silicon carbide target and silver target, and then sputtering the targets simultaneously; wherein the silicon targets act as a bonding layer between the bactericidal film and the substrate; stopping the silicon targets, the silicon carbide targets and the silver targets first, and then turning off the argon gas; injecting air into the chamber until the pressure in the chamber and the atmospheric pressure are balanced.

A protective enhanced-maintenance antiviral coating for interior components of a passenger cabin is disclosed. In embodiments, the enhanced-maintenance antiviral coating incorporates into the antiviral coating indicating agents, e.g., reflective or fluorescent compounds that combine with the antiviral coating without otherwise impeding its antiviral and/or antibacterial properties. The enhanced-maintenance antiviral coating is applied to external surfaces of the interior components of an aircraft cabin or other mobile platform especially prone to frequent physical contact by multiple individuals. The indicating agent reacts via reflectivity and/or fluorescence when ultraviolet (UV) band or otherwise specialized lighting is applied to the external surfaces. A lack of reflectivity or fluorescence may be interpreted as significant wear or damage to the antiviral coating, for which corrective actions may be taken.

A dehaze and bacteriostatic film includes a substrate material layer and a composite surface plasmon layer formed on the substrate material layer. The composite surface plasmon layer includes a particle stacked film layer and a particle suspension layer located on the substrate material layer, and the particle stacked film layer and the particle suspension layer jointly generate a composite surface plasmon wave. Accordingly, the composite surface plasmon wave is excited by visible light, so that different types of surface plasmon waves generated by the structures resonate and multiply with each other. The different surface plasmon waves add up to generate electromagnetic field intensity capable of dissociating spatial materials at a certain distance, such as water vapor to be partially ionized which is rich in hydroxide ions with effects of dehazing and inhibiting growth of bacteria.

[Problem to be Solved]

To provide a cosmetics container or the like capable of reducing bacteria in cosmetic product.

[Solution]

A container main body 20 of the cosmetics container of the present invention is configured of a main body portion 22 that configures the basic structure of the container main body 20 and an inner surface portion 24 that configures the inner surface of the container main body 20. The inner surface portion 24 is configured as a sterilizing portion in which metal fine particles having an effect of reducing bacteria are dispersed in a resin and bacteria are reduced by the action of the fine particles. The fine particles are configured so as not to be exposed on the surface of the inner surface portion 24. The type of metal configuring the sterilizing portion is defined according to the type of bacteria that is assumed to become a problem at each position on the inner surface portion 24.
