According to the present invention, there is provided a method for storing or transporting a viscous liquid.
It is mainly intended for drums and fixed or foldable containers up to the 1000 liter class, and has the following excellent effects. Since the mucus can be discharged while being sealed in an inner bag (liner) made of an easily removable polyethylene film (sheet) or the like, the inside of the container is not contaminated at all. Therefore, the container can be used repeatedly without internal cleaning. Further, it is possible to completely shut off moisture absorption by using a laminate material, and to maintain quality. In addition, a container such as 500 to 1000 liters for mucus can be applied to the folding type, and the collection cost can be reduced greatly as a non-washing folding type container. Since the filling and discharging operations of the mucus can be performed in a state of being closed from the upper and lower openings, there is no fear of contamination of foreign matter or germs, and it is possible to ensure thorough hygiene management and quality control. Since the liner is fixed to the upper shoulder portion and the bottom portion with the use of a stretching member and stretched to prevent suction, the external pressure can be applied to the liner to discharge the viscous filler. Since the liner is sealed in a plurality of radial directions at the top and bottom, and is shaped like a ridgeline and formed into a bag shape, the sheets naturally adhere to each other by pressurization, and almost complete discharge can be performed. In addition, a small container such as a corrugated cardboard which has been conventionally used can be made into a distribution system in which the size is increased, and the cost of container materials can be reduced. Accordingly, there is no need for individual management of cardboard boxes, and no filling work, packing, unpacking work, or discharge work, which has conventionally relied on manual labor, so that labor costs can be greatly reduced. (10) Since it can withstand repeated use, it is not necessary to dispose of the conventional one-way container, and the container cost per unit can be greatly reduced. (11) Waste liquid treatment by washing becomes unnecessary, and environmental measures can be promoted. (12) The pressure for discharging the filling material can be utilized by using air that is piped in the factory, so that a very versatile cargo handling system for mucous liquids can be obtained. Alternatively, a suction pump can be used.
