  • Patent number: 8322355
    Abstract: A non-inserted nozzle for washing a container that can increase the washing efficiency, decrease the amount of washing fluid used, and shorten the washing time in sterilizing and washing a bottle container. The upper end surface of a non-inserted nozzle 8 serves as a liquid-receiving surface 10, and a retention wall 11 of a predetermined height is formed on the outer periphery of the liquid-receiving surface, thereby producing a retention recess. A plurality of nozzle holes 13 linked to a fluid channel of a nozzle stem 14 are provided obliquely so as to spread outwardly substantially in the central section of the liquid-receiving surface. The non-inserted nozzle 8 is disposed below the mouth of an inverted container 28 at a distance H from it and the sterilizing fluid or washing fluid is sprayed from below the mouth of the container, without inserting the nozzle into the container.

  • Publication number: 20120288406
    Abstract: Provided are a method and a device for sterilizing the surface of a space-to-be-sterilized which are safe to the human body, which are effective even for sterilizing spore-forming bacteria, which do not require the space-to-be-sterilized to be highly shielded, and which can sterilize the surface of the space efficiently with inexpensive equipment. The disclosed method involves: spraying a low-concentration sterilizing agent in the form of fine particles into the space-to-be-sterilized and making the sterilizing agent adhere to the surface thereof, the low-concentration sterilizing agent being any one of a 1-10 wt % aqueous solution of hydrogen peroxide, a 0.1-1 wt % aqueous solution of peracetic acid, or a 0.01-0.1 wt % aqueous solution of hypochlorous acid; adjusting the humidity in the space-to-be-sterilized; and air-drying the sterilizing agent. Thus, a high level of sterilization can be achieved in a short time and at low cost.

    Abstract: Provided are a deforming method and device that use laser-induced breakdown. The provided method and device make it possible to shorten the focal distance, thereby improving laser beam convergence, and increase the utilization efficiency of sound waves that contribute to defoaming. Pulsed laser light is focused and irradiated into a space inside an acoustic waveguide (4), thereby generating pulsed sound waves from the illumination point (7). The pulsed sound waves propagate down the acoustic waveguide as plane waves, then propagate beyond an open end (16) as spherical waves, and break up a foam outside the open end of the acoustic wave guide.
