  • Publication number: 20130092196
    Abstract: The purpose of the present invention is to provide a container sterilization method, washing method, and system which retain food hygiene manufacturing standards and a required production line speed, as well as reducing the amount of treatment fluids used such as pharmaceutical fluid, hot water and aseptic water. The container sterilization method and washing method of the present invention is a method in which a container is sterilized/washed using a treatment fluid, and the sterilization step and/or washing step are divided into at least two parts. By storing and pumping upwards the treatment fluid supplied from one part of the divided sterilization or washing step after use, the treatment fluid can be supplied in series to the other part of the same divided sterilization or washing step.

  • Patent number: 8388761
    Abstract: When the inner surface of containers conveyed in an inverted posture is sterilized, the sterilization efficiency can be increased, the amount of sterilizing fluid used can be reduced, the sterilization time and washing time can be shortened, the number of drive components of the apparatus can be reduced and the apparatus can be simplified and reduced in cost. A non-inserted nozzle 20 is disposed at a distance of 1-50 mm below the lower end surface 52 of a mouth of a container conveyed in an inverted posture, the sterilizing fluid is mixed with air and the sterilizing fluid is atomized and sprayed intermittently from the non-inserted nozzle toward the inside of the container.

  • 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.

  • Patent number: 7685794
    Abstract: Cup-shaped containers can be turned over and transferred with good stability from a sterilization-washing zone to the filling-sealing zone inside an aseptic chamber, and admixture of odor or microorganisms is prevented. The first conveyor 2 for conveying the cup-shaped container 38 in an inverted state and a second conveyor 3 for conveying the container in an upright state downstream of the first conveyor 2 are disposed in series in substantially the same plane inside a continuous aseptic chamber 1. A container supply device, a container sterilization device, and a container washing device are disposed successively along the first conveyor 2. A contents filling device 40, a lid material sealing device 41, and a device for discharging the sealed cup-shaped container are installed successively along the second conveyor 3. Sterilization and washing are performed in an inverted state, while conveying the container with the first conveyor 2.

  • Patent number: 4553693
    Abstract: An improved bag-shaped container with a straw insert hole formed thereon is disclosed. The straw insert hole extends through the body of the container and two sealing pieces are adhered to the inner surface of the body to fully close the straw insert hole. Further, a tab is disposed on the outer surface of the body to fully cover the straw insert hole. When an user wants to take the content out of the container, he first peels the tab and then causes a straw to pierce through the second sealing piece until its foremost end part is inserted into the interior of the container. Thus, he is ready to suck the content in the container. To facilitate piercing of the foremost end part of the straw the sealing piece is formed with a small hole or a weakened portion in the form of score.
