By the way, when the inner bag is mounted in the container container, the nozzle must be inserted into the discharge container, but the discharge container is shaped to be vertically stretched from the bottom of the container body and bent horizontally in the middle, for example. Inserting the inner bag from the upper end opening into the container body and inserting the nozzle located at the lower end into the discharge container have a problem that it is very difficult to carry out at the time of work even if the nozzle is flexible.

In addition, when the inner bag is taken out to replace the contents of the container container, the nozzle is drawn into the discharge container. Since the nozzle tip is open, the fluid remaining in the nozzle flows out of the nozzle tip and is discharged into the discharge container or inside the container container. There was a problem of contaminating the filter and then cleaning the discharge container or container container.

Accordingly, the problem of the present invention is that the operation of inserting the nozzle into the discharge container can be performed simply and efficiently, and the cleaning operation can be eliminated without contaminating the inside of the discharge container even when the inner bag is taken out.

The flexible tubular body is generally open at both ends having a diameter approximately equal to the diameter of the corrugation barrel by using polyethylene or the like, and joins one end portion to surround the outer surface of the lower cylindrical portion of the corrugation tube. Although it is folded on an outer surface, when the other end is extended, it becomes normal in the state containing the inside of a corrugated container lower end part, and when this other end is sealed by appropriate means, a nozzle opening part can be closed.

In addition, the string member is connected to the corrugation cylinder through various detachable connection means, such as a cutting | disconnection string or tape, or the locking means by a hole and a hook formed between the string member and a corrugation cylinder, for example.

In this way, the container container has the inner surface of the container body blocked by the inner bag body, and the nozzle is present inside the discharge container, so that there is no contact between the contained fluid and the container container. By simply replacing, cleaning in the container body and in the discharge container is not necessary.

Next, the invention of claim 2 is the container bag inner bag according to claim 1, wherein the string-shaped member has a weight at the distal end portion and a fastening member for tightening and tightening a corrugated tube as a connecting means. It is a constitution.
