Technical field

[0001] The present invention relates to a paper ring-shaped binding tool.

Background art

Conventionally, as a method of binding a plurality of sheets such as a notebook, a calendar or a book, a binding form using an open ring-shaped binding tool is known. This ring-shaped binding tool is made of metal or plastic, and the ring portion is opened to a plurality of binding holes provided in a binding margin portion of a plurality of sheets including a cover. It is used to bind the sheet by passing it through a hole in the paper, but there is also a problem.

[0003] In other words, in light of environmental conservation problems in recent years, in the disposal of used products and articles, the momentum for improving the recyclability of used products and unused products has increased. In addition, it is a point that different materials such as metal and plastic should not be mixed as much as possible for paper products such as notebooks and calendars.

[0004] Binding power of notebooks and calendars When trying to eliminate the use of metal or plastic ones, conventional metal or plastic ring binding tools can no longer be used. Need to develop.

[0005] From this point of view, for example, a calendar binding technique that does not use a metal binding tool for a calendar is proposed as Japanese Patent No. 3243152. There is no substitute for yet. In view of this point, the present inventor has proposed a paper ring-shaped binding tool as Japanese Patent Application No. 2003-349445.

Problems to be solved by the invention

[0006] The present invention further improves the ring-shaped binding tool that can be said to be made of 100% paper and has substantially the same form and function as the conventional metal or plastic ring-shaped binding tool previously proposed. It is an object of the present invention to provide a paper ring-shaped binding tool and a manufacturing method thereof. Means for solving the problem

[0007] The configuration of the binding tool of the present invention made for the purpose of solving the above-mentioned problems is that a substantially comb-tooth shaped portion is formed by cutting on the other end side while leaving a substantially band-like room on one end side of a rectangular hard paper. The entire sheet is formed into a substantially cylindrical shape, and the comb-tooth-shaped portion is passed through a plurality of sheets having binding holes formed at the front end side of the sheet, and then the band-shaped blank portion and the comb of the sheet. It is characterized in that the tip side of the tooth-like part is bonded and bonded. In the present invention, the rectangular hard paper may be formed by an adhesive paper that is double-folded with an adhesive applied to the opposite surface, or may be formed by an adhesive paper in which at least two sheets are laminated with an adhesive. it can. In addition, a paper made of a biodegradable plastic material may be used for this paper. The adhesive paper is formed so as to leave a space on the bent side before the adhesive solidifies, and is cut into a substantially comb-like shape and rounded into a cylindrical shape, with both ends or one end being a cylindrical curvature. On the other hand, the ring-shaped binding tool may be formed by forming it on a flat surface.

[0008] In the binding tool of the present invention using the folded and double-bonded paper, when a sheet is folded in two, a configuration is adopted in which a core paper string or the like is sandwiched inside the fold. Is possible. In this binding tool, in place of the core, or in combination with the core, concave or convex streaks that serve as reinforcing portions along the crease may be inserted.

[0009] The above-described binding tool of the present invention may have a structure in which a rough fabric, a nonwoven fabric, thin Japanese paper, or the like is laminated on the outer surface of a sheet or an adhesive application surface. In the present invention, a thin cloth or nonwoven fabric, or a film made of a natural material or thin Japanese paper may be laminated on the outer surface of the ring-shaped binding tool for the purpose of makeup or reinforcement. In this case, the cloth and nonwoven fabric are preferably made of natural materials. In the binding tool of the present invention, appropriate printing (color, pattern, character, etc.) can be applied to the outer surface of the paper cloth or the like, or the outer surface of the folded paper. Furthermore, the power of using paper that has been waterproofed or moisture-proofed may be used. The finished binding tool of the present invention may be waterproofed or moisture-proofed.

[0010] In the present invention, if plant glue or animal glue is used for the adhesive applied to the paper, all the materials used for the binding tool body of the present invention, including the adhesive, are natural materials. Although it is desirable from the viewpoint of security and environmental conservation, a mixture of these adhesives with a synthetic adhesive can be used. [0011] The configuration of the above-described binding tool manufacturing method of the present invention is a molding in which a rectangular hard sheet is cut into a comb shape while leaving a strip-shaped room on one end side to form a comb-like shape. And at least one end side of the belt-like margin portion and the comb-like portion of the round-formed paper is formed flat so that the comb-like portion is free of the belt-like margin due to the elasticity of the paper. It is characterized in that it is shaped to form a ring that can be freely opened and closed with respect to the part.

The invention's effect

[0012] According to the present invention, a used notebook or calender is formed by forming a sheet binding tool bound to a notebook or calendar with paper only or an adhesive made of paper and a natural material. It is possible to send one to a process such as recycling in a batch without changing the components.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, an embodiment of the binding tool of the present invention will be described. Fig. 1 is a perspective view of an example of a square paper using relatively thick paper forming the ring binding tool of the present invention. Fig. 2 is a perspective view of the paper shown in Fig. 1 folded and bonded. Fig. 3 is a perspective view of the folded sheet of Fig. 2 cut into a substantially comb-like shape, and Fig. 4 is a shape of the substantially comb-like paper of Fig. 3, which is rounded into a cylindrical shape and formed into a cylinder. FIG. 5 is a perspective view of an example formed on the binding tool of the present invention before bonding, in which both ends of the outer shape (the band-shaped margin and the tip end side of the comb-shaped portion) can be bonded. 6 is an enlarged side sectional view of another example of the binding tool of the present invention, FIG. 7 is a side sectional view of the binding tool of the present invention of FIGS. 4 and 5, and FIG. FIG. 3 is a side cross-sectional view of a state in which the joint is hidden between sheets bound together.

[0014] An example of the binding tool of the present invention illustrated in FIGS. 1 to 5 is a rectangular paper having a width of 4 to 6 cm and a length of about 8 to 12 cm, which is relatively thick (for example, about 0.2 to 0.5 mm). 1 (hereinafter referred to simply as “paper”, but the material is plain paper, fiber paper, sulfuric acid paper, dalasin paper, biodegradable synthetic paper, etc.). That is, in order to fold the paper 1 in FIG. 1 in the longitudinal direction, the paper 1 is folded in half, and is folded on at least one of the surfaces la and lb which become opposing surfaces, and in FIG. Apply adhesive 2 such as glue. The adhesive of the present invention is not limited to glue or glue. [0015] The paper 1 coated with the adhesive 2 is folded in half at the fold line 3 at the intermediate portion with the coated surface of the adhesive 2 inside (inner surface) to obtain the state shown in FIG. In the present invention, before the adhesive 2 is solidified in the two-fold state of FIG. By forming (cutting) the grooves 4 at an equal pitch, the whole is formed in a substantially comb-like shape, leaving a band-like room and a comb-like tooth portion 5 (see FIG. 3). In the present invention, the number of grooves 4 (the number of tooth portions 5) can be arbitrarily set according to the balance between the size of the paper 1 and the width of the groove 4 to be cut (the remaining tooth portions 5).

[0016] The two-folded paper 1 of Fig. 3 formed in a comb-teeth shape is formed so that the adhesive 2 of Fig. 3 is unsolidified and rolled up to form a cylindrical shape on the upper surface side 1 of the paper 1 outside. Apply. As an example, the forming method for rounding is performed by pressing a core rod (not shown) with a round cross section so that the paper 1 in FIG. 3 sticks, and in this state, the adhesive 2 is drier (not shown). Force to dry. The forming method for rolling the paper 1 into a cylindrical shape is not limited to the above-described form of using the core rod. Also, the force with which the cylindrical outer diameter is arbitrary is preferably about 5, 6 to 15 mm.

[0017] In the present invention, following the forming of the paper 1 into a cylinder, at least one outer end portion (the band-shaped margin portion side or the tip side of the comb-like portion) of the rounded cylindrical body is formed in the turn portion 6c. The flat end 6a and the non-flat end that is rounded as it is is flattened without bending (see Fig. 5). 6b (See Fig. 5 and Fig. 6). As will be described later, the adhering portion 6 is bonded and fixed after binding a sheet into each tooth portion 5 of the comb-like portion. Further, in the present invention, both outer end portions of the rounded cylindrical body (the belt side margin portion and the tip side of the comb tooth portion) are formed in a flat shape opposite to each other, and the both flat support portions are joined. It may be fixed by bonding.

Here, when forming the paper 1 of FIG. 3 into a cylindrical shape, the folded paper 1 is still in the state where the adhesive 2 is not solidified, and the adhesive 2 is infiltrated into the paper 1. Therefore, when adhesive 2 is solidified by forced drying after round forming, as shown in Fig. 4 and Fig. 5, paper 1 with adhesive 2 dried after round forming is not restored. It is solidified in the state of being rolled into a cylinder.

[0019] The above-mentioned folded and laminated paper 1 rounded portion and bonded fixing portion 6 are formed and bonded. Since the cylindrical shape is fixed in the shape shown in Fig. 5 due to the solidifying action of the agent 2, each tooth portion 5 in the binding device of the present invention has the same strength as that of a plastic or metal ring. It can be used as a ring-shaped binding tool as an openable / closable ring body that exhibits sufficient panel properties (elasticity).

[0020] In the above embodiment, the paper 1 to be formed on the binding tool of the present invention is one in which one sheet is folded in two and the opposite surface is bonded with the adhesive 2. It is also possible to use paper 1 in which individual sheets are laminated with adhesive 2. For paper 1, fiber paper or sulfuric acid paper can be used. When thin paper is used, it may be laminated with adhesive 2 as in the above example, but when thick paper is used. In the ring-shaped binding of the present invention, the groove 4 and the tooth portion 5 are formed on the paper leaving a strip-like space, and the paper is formed into a cylindrical shape rounded in, for example, a steam atmosphere and forcedly dried after forming. There is a tendency to form in the ingredients.

[0021] In addition, the configuration of the flat portion 6a and the non-flat end portion 6b in the paper rounded into a cylindrical shape may be as illustrated in FIG. The flat portion 6a in the example of FIG. 6 is not formed by bending the turn portion 6c in the opposite direction to the curved surface of the outer surface of the cylindrical body as in the example of FIG. Form a flat part 6a that extends straight from the outer surface of the body.

[0022] Furthermore, in the ring-shaped binding tool of the present invention, although not shown, the flat portion 6a is formed on the tip side of each tooth portion 5, and the non-flat portion 6b with the curvature of the cylindrical body is formed at the root of each tooth 5. It may be formed on the side of the bent part 3 that hits (the side of the belt-like room).

[0023] The binding tool of the present invention having the above-described configuration has each tooth portion as shown in Fig. 7 before the flat portion 6a and the non-flat portion 6b facing the flat portion 6a are bonded and fixed with an adhesive. Sheet paper P such as notebook paper, calendar paper, etc., in which holes h matching the pitch of each tooth 5 are arranged from the tip of 5 (the non-flat portion 6b in the examples of FIGS. 5 and 6). Binding is performed by passing the holes h through the respective tooth portions 5, and then the tip of the non-flat portion 6b is brought into contact with the flat portion 6a, and the contact portion is joined by the adhesive 7 and joined. The fixed part 6 is fixed, and the bookbinding is completed. An example of the bookbinding completion status is as illustrated in Fig. 7.

In the binding tool of the present invention, as illustrated in FIG. 7, when the sheet p is bound, the flat portion 6a and the non-flat portion 6b are bonded with an adhesive, and the adhesive 7 of the bonded fixing portion 6 is solidified. Connect flat part 6a An excess portion that does not interfere with the adhering portion 6 due to the adhesive 7 may be cut (not shown). If not cut, a locking hole H may be provided on both sides of the flat surface of the flat portion 6a (see FIG. 7).

[0025] Further, in the binding tool of the present invention, since the flat portion 6a is force flat, if the flat flat portion 6a is positioned between the sheets p bound as shown in FIG. Since the eyes are not exposed to the outside of the book (notebook, calendar, etc.), it is possible to realize a bookbinding state using a ring-shaped binding tool with excellent appearance.

[0026] In the present invention, the following embodiments can be adopted in addition to the above example.

First, in the present invention, by selecting the thickness and size of the paper 1 to be used, a paper ring in which the length of the tooth portion 5 (ring diameter) and the number of tooth portions 5 (rings) are arbitrarily set. You can form a binding tool. In the present invention, the following embodiments can be adopted.

[0027] For example, by laminating a non-illustrated natural fabric or non-woven fabric, which is not shown, on the adhesive surface of the paper 1, even if the paper 1 used is thin, sufficient strength can be achieved. It can be expressed and further improve their performance. Those using thick paper will further enhance their performance.

[0028] Further, when a paper string, for example, is inserted into the inside of the fold 3 along the crease 3 in the paper 1 of Fig. 1 that is folded in half, this is the length in the length direction of the binding tool of the present invention. As a result, the strength can be increased. For this purpose, in the present invention, when a line having a concave or convex surface along the crease 3 of the folded paper 1 is inserted, this also acts as a reinforcing line, so that the line is used together with the paper string core. Or it can be applied alone. In the present invention, in order to cope with the case where each rounded tooth portion 5 is solidified and opened by an adhesive, a concave shape (not shown) is provided in the transverse direction of each tooth portion 5 in order to help open the ring. There is also.

In the present invention, in order to increase the strength of the binding tool or to improve the appearance of the binding tool, a cloth or the like is applied to at least the outer surface of the folded paper 1 (for example, the upper surface If in FIG. 3). In addition to increasing the strength by layering, the texture of the binding tool can be made to look like a desired material, and it can be decorated by printing colors, patterns, letters, etc. Further, the finished binding tool of the present invention may be waterproofed or moisture-proofed. Industrial applicability

[0030] The present invention is as described above, and a paper ring-shaped binding tool having substantially the same function and performance as a plastic or metal ring-shaped binding tool can be provided by using paper and an adhesive. If a tool is used as a means to bind a large number of sheets like a notebook or calendar, it can be disposed of as it is without being separated from the node body or calendar body after use.

[0031] In particular, in the binding tool of the present invention, when a sheet is rolled into a cylindrical shape and formed into a ring shape, a flat flat portion is formed at both ends thereof, and a cylindrical curvature that is bonded and integrated to the flat portion by adhesion. Form a non-flat part as it is, or form the flat part on both ends of a ring shape that is rounded into a cylindrical shape, bind the hole in the sheet through each ring-shaped tooth, and then Since the flat part and the non-flat part are bonded and solidified with an adhesive, or both flat parts are bonded and solidified into a jointed shape so that the ring does not open, the bonded flat part is attached to this binding tool. It can be sandwiched between sheets such as calendars and notebooks to be bound, and the joint of the ring body is not exposed at all to the outside of the calendars and notebooks to which it is bound. Will also be good.
