Abstract

A paper-made staple binds a sheet bundle subjected to folding processing by a folding blade and a folding roller. The paper-made staple includes a pair of leg portions inserted into the sheet bundle and then bent inward; and a connection portion that connects the leg portions in a staple longitudinal direction. The connection portion has, at an edge portion thereof, a cut in a direction crossing the longitudinal direction so as to correspond to a predetermined folding position of the sheet bundle for the purpose of facilitating the folding of the connection portion, and the cut is formed inward from the edge portion so as to have a substantially triangular shape and is provided on both edge portions of the connection portion of the paper-made staple.

First claim

What is claimed is:

1. A paper-made staple to bind a sheet bundle, comprising:
a pair of leg portions adapted to be inserted into the sheet bundle and then bent inward; and
a connection portion that connects the leg portions in a staple longitudinal direction,
wherein the connection portion has, at an edge portion thereof, a cut in a direction crossing the longitudinal direction so as to correspond to a predetermined folding position of the sheet bundle for facilitating folding of the connection portion.

2. The paper-made staple according to claim 1 , wherein the cut is formed inward from the edge portion so as to have a substantially triangular shape and is provided on two edge portions of the connection portion of the paper-made staple.

3. The paper-made staple according to claim 1 , wherein an adhesive portion through which the inwardly bent leg portions bent to each other is provided on the pair of leg portions to be inserted into the sheet bundle.

4. The paper-made staple according to claim 1 , wherein each of the leg portions has a leg portion side cut at a position overlapping the cut of the connection portion when the leg portions are bent inward.

5. The paper-made staple according to claim 4 , wherein a width of the leg portion side cut in the longitudinal direction of the paper-made staple is set larger than a width of the connection portion cut in the longitudinal direction.

6. A paper-made staple assembly comprising a plurality of paper-made staples as claimed in claim 1 , wherein said plurality of paper-made staples are partly connected in a direction crossing a longitudinal direction of the paper-made staples.

7. A paper-made staple to bind a sheet bundle, comprising:
a pair of leg portions adapted to be inserted into the sheet bundle and then bent inward; and
a connection portion that connects the leg portions in a staple longitudinal direction at a position straddling a predetermined folding position,
wherein the connection portion has, at an edge portion thereof, a cut in a direction crossing the longitudinal direction so as to correspond to a predetermined folding position of the sheet bundle for facilitating folding of the connection portion.

8. The paper-made staple according to claim 7 , wherein the cut is formed inward from the edge portion so as to have a substantially triangular shape and is provided on two edge portions of the connection portion of the paper-made staple.

9. The paper-made staple according to claim 7 , wherein an adhesive portion through which the inwardly bent leg portions bent to each other is provided on the pair of leg portions to be inserted into the sheet bundle.

10. The paper-made staple according to claim 7 , wherein
each of the leg portions has a leg portion side cut at a position overlapping the cut of the connection portion when the leg portions are bent inward.

11. The paper-made staple according to claim 10 , wherein a width of the leg portion side cut in the longitudinal direction of the paper-made staple is set larger than a width of the connection portion cut in the longitudinal direction.

12. A paper-made staple assembly comprising a plurality of paper-made staples as claimed in claim 7 , wherein said plurality of paper-made staples is partly connected in a direction crossing a longitudinal direction of the paper-made staples.

13. The paper-made staple assembly according to claim 12 , wherein the paper-made staples partly connected to each other as the paper-made staple assembly are wound in a roll shape.

14. The paper-made staple assembly according to claim 7 , wherein the paper-made staples partly connected to each other as the paper-made staple assembly are wound in a roll shape.
