Description

  The present invention relates to a paper binding tool that binds a booklet in which a plurality of papers are bundled, such as a calendar, without using an adhesive or a stopper.

Conventionally, when binding a plurality of papers and binding a booklet that has been turned like a calendar and then peeled off, a method of passing a needle through a plurality of papers like a stapler or sandwiching a metal plate with a booklet, We know how to fold and bind while pressing, how to make a lot of holes and inject a resin material such as hot melt and bond it to cardboard, and how to pass a metal binding tool processed into a ring shape into a number of holes. It has been.
Eco-friendly binding tools made only of paper have been developed to avoid the use of materials that cause pollution when incinerated, such as adhesives made of metal, plastic, and synthetic resin, and to facilitate separation and recycling. Yes.

Conventionally, a calendar using a paper binding tool having a binding structure that is sufficiently strong only with a cardboard binding tool without using an adhesive such as hot melt is known (see Patent Document 1). ).
In this known technique, a reinforcing piece is connected to the lower side of the binding piece of the cardboard binding tool that binds the upper part of the calendar booklet, and these reinforcing pieces are folded inwardly inside the binding piece, thereby forming the reinforcing piece. A repulsive force to return to the original is generated, and the bookbinding portion is sandwiched and supported by the binding piece without using an adhesive by using this repulsive force, and the locking side provided on one binding piece is the upper end of the booklet. After passing through the insertion hole provided in the binding portion, it is inserted into the insertion hole provided between the other binding piece and the reinforcing piece.

However, when making a paper binding tool that is firmly fixed, such as a plastic or metal binding tool, you can fold the thick paper twice and attach it with increased strength. In the case of a calendar binding tool of a type in which the paper is glued and bound and then peeled off like a month, it is made by ring-shaped without passing the method of fixing the paper and passing through the insertion groove of the booklet part. The effect of suppressing the spread of the paper from the paper was weak, and there was a problem in the strength when peeling off.

  The purpose of the present invention is to provide a paper binding tool capable of binding firmly even if it is not extremely thick paper, while firmly pressing the side of a booklet such as a calendar without using an adhesive. To do.

  The paper binding tool of the present invention includes a rectangular cover body having a width of a booklet such as a calendar, and a back surface of the booklet via a binding margin portion corresponding to the thickness of the booklet on the short side of the cover body. A side insertion piece to be inserted on the side is integrally formed with a short side width of the cover body, and the back surface through the booklet insertion groove at a position corresponding to the booklet insertion groove formed on the booklet on the long side of the cover body A bent-sheet stopper piece of a length that extends to the side is projected and formed on the long side opposite to the cover body with the same shape as the cover body 1 via a binding margin portion corresponding to the thickness of the booklet A backing paper main body is formed integrally, and the back paper main body has a notch groove into which the folding paper stopper piece of the cover main body is inserted and fixed to the back paper main body portion that matches the booklet insertion groove formed in the booklet. Formed on the left and right sides of the long side of the backing paper body In which a side folded piece to form each short side end of the paper body in the width and length of the side insertion pieces of the cover body extended direction.

The paper binding tool of the present invention has a folding portion that fixes the side that stops the left and right sides from the side direction, so that it does not adhere due to the interaction of the main body booklet, side side, back side, side side guide stopper There is an effect that does not come off even when pulled and does not come off even if it hits.
Because there is a left and right guide, it can be fixed even if the width of the insertion groove is slightly different.
The size of the control groove is larger than that of the anchoring portion, so that the whole can be aligned and fixed.
Further, only one insertion groove is possible.
Even if thin paper or a part that becomes a backing sheet for writing is required, it is possible to attach the same paper quality as the stopper because the part to be folded is partly.
Because it is an assembly mold that does not require bonding, it can be reassembled even if it is disassembled.
Further, it is easy to separate the booklet portion and the binding portion.
By increasing the length of the locking part and increasing the number of insertion grooves, it is possible to bind hundreds of sheets of paper.

One embodiment of the paper binding tool of the present invention will be described below with reference to the accompanying drawings.
As shown in the developed view of the paper binding tool of the present invention in FIG. 1, a rectangular cover body 1 having a width of a booklet L like a calendar, and the thickness of the booklet on the short side of the cover body A side insertion piece 3 to be inserted into the back side of the booklet through the binding margin portion 2 is integrally formed with a short side width of the cover body 1.
Further, a bent paper stop piece 4 having a length that passes through the booklet insertion groove to the back side is formed in a protruding manner on the long side of the cover body 1 at a position corresponding to the booklet insertion groove M formed in the booklet L.
Then, a back paper body 5 having the same shape as that of the cover body 1 is integrally formed on the long side opposite to the cover body 1 through a binding margin 2 corresponding to the thickness of the booklet.
Further, the backing paper main body 5 is formed with notch grooves 6 into which the folded paper stopper pieces 3 of the cover main body 1 are inserted and fixed in the backing paper main body 5 portion that coincides with the booklet insertion groove formed in the booklet. To do.
Further, side folds 7 are formed with the width and length of the side insertion piece 3 of the cover main body 1 in the direction in which the short side end of the back paper main body 5 is extended on both the left and right sides of the long side of the backing paper main body 5. Form each one.

Next, the assembling operation of the paper binding tool of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 2, the paper binding tool of the present invention is folded in the center around a binding margin 2 formed between a cover main body 1 and a back paper main body 5, and a side insertion piece 3 of the cover main body 1. Is bent until it contacts the back surface of the cover body 1.
Next, as shown in FIG. 3, the side folded piece 7 of the backing paper main body 5 is inserted between the cover main body 1 and the side inserted piece 3. 3 is further returned, and as shown in FIG. 4, the booklet so that the folded-sheet stopper piece 4 of the cover body 1 comes to the position of the booklet insertion groove M of the booklet L like a calendar. Insert so that the upper part of L is between the cover main body 1 and the back paper main body 5, and fold the folding paper stopper 4 into the booklet insertion groove M as shown in FIG. . Then, as shown in FIG. 6, the folded paper stopper piece 4 protruding on the back surface of the booklet L is bent and fixed through the cut groove 6 of the backing paper body 5 to complete.

In the above-described assembling operation of the paper binding tool, the semi-finished product is formed to assemble the paper binding tool. However, the finished product can be formed while completely assembled.
As shown in FIG. 7, the folded paper stopper 4 is passed through the booklet insertion groove M of the booklet L like a calendar from the front surface to the back surface, and as shown in FIG. Bend until it touches the booklet L.
As shown in FIG. 9, the backing paper body 5 is bent until it overlaps the booklet L side around the binding margin 2 formed between the cover body 1 and the backing paper body 5, and as shown in FIG. 10. The side folding piece 7 is inserted between the cover body 1 and the side insertion piece 3.
Finally, the folded paper stop piece 4 on the back surface is folded and fixed through the cut groove 6 of the backing paper main body 5 to complete.
