Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid container used to transport various chemicals, foods and drinks, and other liquids.

[0002]

[Prior art]

 As a liquid container for storing and transporting liquids such as various chemicals and foods and drinks, metal tanks such as stainless steel and synthetic resin tanks such as polyethylene are generally used from the viewpoint of safety. In addition, a container in which a liquid bag made of synthetic resin film or sheet is combined with an outer frame such as a box made of a rigid body is also used.

Depending on the liquid to be stored, it is necessary to sterilize and use the metal tank and the synthetic resin tank described above, for example, steam sterilization or sodium hypochlorite sterilization is possible. However, it is inefficient and costly. This type of tank is designed for repeated use, but the inner surface must be cleaned and sterilized after each repeated use. In particular, the larger the capacity of a large tank, the more difficult it becomes to sterilize and clean it.

On the other hand, a bag made of a synthetic resin film such as a polyethylene film can be sterilized by irradiation with gamma rays, and a large number can be sterilized at the same time in a low-volume folded state, and moreover, compared to a tank or the like. It can be manufactured at low cost. Therefore, we decided to combine this synthetic resin film bag with a rigid outer frame such as a box and use it in a liquid container that needs to be sterilized before use.

However, the synthetic resin film bag has a safety problem such as a possibility of pinholes and the like, which may cause liquid leakage during transportation. In particular, once the liquid leaks, the inner surface of the outer frame may become dirty and damaged, and the entire contents may be defective from the viewpoint of hygiene.

The present invention has been made in view of the above, and as a liquid container in which an inner bag made of a synthetic resin film that is easy to sterilize is combined with an outer frame such as a box, liquid leaks from the inner bag. Even if it occurs, there is no risk of polluting the inner surface of the outer frame or outflowing to the outside, and it is highly safe.In addition, repeated use of the outer frame does not require cleaning, etc., and sterilization is required. The purpose of the present invention is to provide a low cost liquid container that can be conveniently used for liquid transportation when there is a need.

[0007]

[Means for Solving the Problems]

 The liquid container of the present invention that solves the above problems is formed in a bag shape that opens upward by an outer frame such as a metal box having an outlet at the lower end of the side surface and a flexible impermeable sheet. And a safety bag that is installed inside the outer frame and an inner bag made of a synthetic resin film that is inserted inside the safety bag.An opening is formed at the lower end of the side surface of the safety bag that corresponds to the outlet. A discharge outer cylinder is provided continuously at the opening, and a discharge opening is provided at the lower end of the side surface of the inner bag, and a discharge cylinder extending outward is continuously provided at the opening. A cylinder is inserted into the discharge outer cylinder, and the overlapping portion of both is provided so as to be integrally sealed by a sealing means such as a clip.

[0008]

[Action]

 According to the present invention described above, the liquid is contained in the inner bag made of the synthetic resin film. The inner bag is doubly protected by the safety bag and the outer frame, and even if a pinhole occurs in the inner bag and liquid leaks, the leaked liquid is made up of a non-permeable sheet. It is retained inside the bag and therefore does not pollute the inside of the outer frame or leak outside.

In particular, the discharge cylinder connected to the opening at the lower end of the side surface of the inner bag is inserted into the discharge outer cylinder provided at the lower end of the side surface of the safety bag to form a polymerized state. Since both are sealed together by a sealing means such as a clip in the odor, even if liquid leaks from the inner bag as described above, the leaked liquid will flow out through the opening of the safety bag. Nor.

Moreover, the inner bag made of the synthetic resin film described above can be effectively sterilized in a state in which it is folded in a low volume, and even if the inner bag is replaced, cleaning is not required. The outer frame and safety bag can be used repeatedly.
