A pass box configured to accommodate and decontaminate an article by concentrating a mist of decontamination agent on an article's surface and to reduce a duration of aeration operations. The box includes a decontamination chamber, an aeration chamber in which residue of the decontamination agent is removed from the article's surface, a decontamination agent supply device, a decontamination agent control device, a moving device configured to reposition the article, and an air supply and exhaust device. The decontamination agent supply device converts a chemical into the mist and supplies it into the decontamination chamber. The decontamination agent control device includes vibration boards that are adjacent to internal wall surfaces of the decontamination chamber and that are ultrasonically vibrated to generate sound flows in the vertical direction thereby pressing the mist with acoustic radiation to concentrate the mist on the external surfaces of the article.

The mist control means includes vibration boards adjacent to internal wall surfaces of the decontamination region, and these boards are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The mist inside the decontamination region is pressed by acoustic radiation to concentrate the mist on external surfaces of the article conveyed inside the decontamination region.

Continuous decontamination device

A decontamination device devised to accomplish decontamination with a proper amount of decontamination agent by employing a mist control mechanism to concentrate a mist for decontamination on the surface of an article to be conveyed, and to reduce duration of operations such as aeration increase efficiency of decontamination, and a pass box in which the decontamination device is disposed. The device also includes a mist supply means configured to convert a chemical for decontamination into the mist, and to supply the mist to the inside of a working chamber accommodating the article. The mist control mechanism includes vibration boards adjacent to internal wall surfaces of the working chamber, which are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The mist supplied to the inside of the chamber is pressed by acoustic radiation pressure to be concentrated on external surfaces of the article.

A continuous decontamination-and-sterilization device possessing high efficiency, reliability, and safety of operation to treat external surfaces of a package that is conveyed to a sterile working chamber. A decontamination chamber decontaminates (with a decontamination agent) bottom and lateral external surfaces of the package conveyed by a first conveyance, with an upper surface seal portion of the package being sealed. An aeration chamber removes residue of decontamination agent from an external surface of the package while the package is conveyed by a second conveyance means. A sterilization chamber sterilizes the upper surface seal portion of the package by irradiating electron beams as the package is conveyed by a third conveyance means, with the bottom or lateral external surface of the package being supported. The first conveyance means includes a sealing means by an adsorbing function to adsorb and capture the upper surface seal portion so as to seal the same and convey the package, with the bottom and lateral external surface portions of the package being open.
