There is one that is connected by a communication hole, the communication hole is opened at the joint portion for the bag-shaped container, and the content introduction portion is composed of a pipe-shaped leg connected to the joint portion for the bag-shaped container.

[0004] However, in the contents introducing portion composed of the pipe-like legs, the jelly-like contents pass through the pipe, so that they become non-uniform solidified in the shape of a rod and are clogged by the internal communication holes (blockage). There was a problem such as.

As another spouting device for the container as described above, there is, for example, a device having a plate-shaped leg body whose content introducing portion is connected to the joint portion for the bag-shaped container.

[0006] However, in the contents introducing section composed of the plate-like legs, the jelly-like contents are easily separated by the plate-like legs and become a large mass, so that the jelly-like contents are clogged (blocked) by the internal communication holes. There is a problem that phenomena such as) are likely to occur. Further, since the legs are plate-shaped, there are problems that the molded product is warped, and that it is easily deformed by heat during storage and transfer after molding.

Further, as another spouting device for a container as described above, for example, a device having a cross-shaped rib leg body in which vertical and horizontal ribs whose contents introduction part is connected to the joint part for bag-shaped container are orthogonal to each other There is.

However, in the case of the contents introducing portion composed of the leg portions having the cross-shaped ribs, the jelly-like contents are relatively uniformly crushed by the leg portions having the cross-shaped ribs and come out.
