Document Type and Number:
Japanese Patent JP2015003416
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a paper-made ring-shaped binder that can be manufactured at a higher efficiency than in a prior art.SOLUTION: A paper-made ring-shaped binder 10 is manufactured by rounding a paperboard strip. This binder integrally has a male-side joint 72 and a female-side joint 74. The male-side joint integrally has a head 90 and a side flap 94 extending crosswise from the head. The flap can be folded to the head, thereby selectively being turned into a development state in which the flap overhangs from the head outwardly in the crosswise direction, a fallen state in which the flap is folded to the head inwardly in the crosswise direction, and a standing state in which the flap stands from the fallen state. The flap is inserted into the slit 80 of the female-side joint in a fallen state and then turned from the fallen state to a standing state by the elastic recovery of the male-side joint, so that the male-side joint is mechanically locked by the female-side joint.
