[0012]

According to the first to third aspects of the present invention,
In the through hole 3 formed in the middle portion of the top wall 2 of the cap body 1,
An elastically reversible closed cylinder spring 5 is mounted on the top wall 2 of the elastically deformable soft material pouring cylinder 4 at the base so as to stand upright, and an elastic reversing closed cylinder spring 5 is attached to the pouring cylinder 4. Since the elastic reversing closed cylindrical spring 5 is moved forward and backward with respect to the pouring cylinder 4, the upright pouring cylinder 4 is elastically deformed to be folded or folded. It is possible to make the dispensing cylinder 4 upright by the elastic restoring force, and when it is folded, the dispensing cylinder 4 can be reliably closed by the closing force by elastic deformation. With the elastic restoring force, the open cylinder state can be maintained, and the pouring cylinder 4 can be opened appropriately. Therefore, the pouring cylinder 4 can be extremely easily and accurately operated only by pressing the elastic reversing closed cylinder spring 5.
