PROBLEM TO BE SOLVED: To improve the handleability of a spool with a storage container, when it is connected to a plurality of similar storage containers. SOLUTION: An engaging portion 46 of a storage container 3 is engaged with a projected portion 63D of a storage container 3D in the axial direction to detachably coaxially connect the storage containers 3, 3D to each other, and consequently, a spool 1 with the storage container is coaxially piled and is detachably connected to a similar spool 1D with the storage container. Here, since an insertion portion 53 is formed in a lid 5, while the engaging portion 46 is extended in the circumferential direction and has a space 47, an insertion portion 53D of a lid 5D is inserted into the space 47 of the engaging portion 46. Thus, according to the spool 1 with the storage container detachably to the other spool 1D with the storage container can be piled and connected in the axial direction, relative rotation of the storage containers 3, 3D is limited in the connected state; while the storage containers 3, 3D are positioned in the circumferential direction.
