Description

  The present invention relates to a paper ring-shaped binding tool and a method for manufacturing the same.

  2. Description of the Related Art Conventionally, as a method for binding a notebook, calendar, or 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 a ring portion is opened from the open portion of the plurality of binding holes provided in a binding margin portion of a plurality of sheets including a cover from the open portion of the sheet. Although it is used to bind the sheet by passing it through a hole, there is a problem.

  In other words, due to recent environmental conservation issues, in the disposal of used products and articles, there is a growing momentum to improve the recyclability of used products and unused products. In paper products such as metal, plastics and other foreign materials are not mixed as much as possible.

  If you try to exclude the use of metal or plastic bindings from notebooks and calendar bindings, conventional metal or plastic ring bindings cannot be used, so develop alternative bindings and binding forms. Need arises.

  From such a viewpoint, for example, a calendar binding technique that does not use a metal binding tool for a calendar is proposed as Japanese Patent No. 3243152. However, an alternative to a metal or plastic ring binding tool is available. I haven't found it yet.

  Therefore, in the present invention, it is an object to provide a ring-shaped binding tool that can be said to be made of 100% paper having substantially the same form and function as a conventional metal or plastic ring-shaped binding tool, and a method for manufacturing the same. Is.

  The structure of the manufacturing method of the binding tool of the present invention made for the purpose of solving the above-mentioned problem is that the paper with the adhesive on the opposite surface is folded in two and bonded, and the above 2 before the adhesive is solidified. The main feature is that the paper that is folded and double-bonded is cut into a substantially comb-like shape, then rolled into a cylindrical shape, and dried in this state to fix the cylindrical shape. It is what.

  The configuration of the binding tool of the present invention formed by the above-described manufacturing method is such that a sheet of paper with an adhesive on the opposite surface is folded in two and bonded to form a substantially comb-like shape before the adhesive is solidified. The main feature is that the comb-shaped portion is formed into a ring shape having elasticity by cutting the shape into a cylindrical shape and rounding it into a cylindrical shape due to the difference in circumference between the inner and outer surfaces of the rolled double paper and the solidification of the adhesive. It is what.

  In the binding tool of the present invention, when a sheet of paper is folded in two, a configuration in which a paper string or the like serving as a core is sandwiched inside the fold may be employed. In the binding tool of the present invention, 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.

  Next, the binding tool of the present invention may have a structure in which a coarse cloth or nonwoven fabric or thin Japanese paper is laminated on the 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 a natural material. In addition, in the binding tool of the present invention, appropriate printing (color, pattern, character, etc.) can be applied to the outer surface of the fabric cloth or the outer surface of the folded paper.

  Furthermore, in the present invention, if the adhesive to be applied to the paper is plant glue or animal glue, all of the binder and the adhesive used are natural materials, so from the viewpoint of recyclability or environmental protection. Is also desirable.

  In the present invention, since a sheet binding tool such as a notebook or calendar is formed by using an adhesive made of paper and a natural material, the used notebook or calendar is collectively processed without separating components. Can be turned to.

  The embodiment of the binding tool of the present invention will be described with reference to the drawings. 1 is a perspective view of a relatively thick paper forming the ring-shaped binding tool of the present invention, FIG. 2 is a perspective view of a state in which the paper of FIG. 1 is folded and bonded, and FIG. 3 is a folded paper of FIG. FIG. 4 is a perspective view of the binding tool of the present invention in which the substantially comb-like paper of FIG. 3 is rolled into a cylindrical shape and solidified, and FIG. 5 is a perspective view of FIG. It is -A arrow enlarged cross-section (end surface) figure.

  An example of the binding tool of the present invention shown in the drawing is formed of a relatively thick paper 1 having a rectangular shape with a width of 4 to 6 cm and a length of about 5 to 7 cm. That is, in order to fold the paper 1 in FIG. 1 in the longitudinal direction, the paper 1 is folded in half and bonded to at least one of the opposing surfaces 1a and 1b, in FIG. 1 to the surface 1a, preferably by glue or glue. Agent 2 is applied. The adhesive of the present invention is not limited to glue or glue.

  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. Before the adhesive 2 is solidified in the two-folded state of FIG. 2, grooves 4 that are opened on the side without the folds 3 of the two-folded paper 1 are formed at an equal pitch by a press blade or the like, and the teeth are comb-like. The whole is formed in a substantially comb-like shape, leaving 5 (see FIG. 3).

  The two-folded paper 1 of FIG. 3 formed in a comb shape is rolled so as to form a cylindrical shape with the upper surface side 1f of the paper 1 being outside in the state where the adhesive is not solidified in FIG. For example, the rounding is performed by winding the paper 1 of FIG. 3 around a core rod (not shown) having a round cross section, and in this state, the adhesive 2 is forcibly dried by a dryer or the like. In addition, how to round the paper 1 is not limited to the above-described form of using the core rod.

  Here, when the paper 1 of FIG. 3 is rolled, the folded paper 1 is still in a state where the adhesive 2 is not solidified, so that the thickness of the paper 1 causes the cylindrical inner and outer surfaces at the time of cylindrical molding. Due to the difference in circumference, a deviation F occurs between the leading edge of the paper 1 on the inner side (lower 1u in FIG. 3) and the leading edge of the paper 1 on the outer side (upper 1f in FIG. 3). Since the adhesive 2 is solidified by forced drying in the state in which the deviation F occurs, as shown in FIGS. 4 and 5, the folded and folded paper 1 is solidified without returning to the original state. End up.

  Each of the teeth 5 in the binding tool of the present invention formed and fixed in the form of FIG. 5 by the rounding of the folded paper 1 and the solidifying action of the adhesive 2 is as if it were a plastic or metal ring. It exhibits springiness (elasticity) and can be used as a ring-shaped binding tool.

  In the present invention, by selecting the thickness and size of the paper to be used, the ring-shaped binding tool made of paper in which the length of the tooth portion 5 (ring diameter) and the number of the tooth portions 5 (ring) are arbitrarily set. Can be formed.

  In the present invention, a sufficient strength can be obtained even if the paper 1 to be used is thin by laminating a cloth or nonwoven fabric of a natural material (not shown) on the two-fold adhesive surface of the paper 1 in FIG. And spring properties can be developed, and further, their performance can be improved. Those using thick paper will further enhance their performance.

  Furthermore, when a paper string, for example, is placed inside the fold 3 along the fold 3 in the paper 1 of FIG. 1 that is folded in half, this becomes a fulcrum in the length direction of the binding tool of the present invention, and the strength Can be increased. For this purpose, in the present invention, when a line having a concave or convex cross section is inserted along the crease 3 of the folded paper 1, this also acts as a reinforcing line, so that the line is used in combination with a paper string core. Or it can be applied alone. Further, in the present invention, in order to cope with the case where each rounded tooth portion 5 is hardened by an adhesive and difficult to open, as shown by a virtual line in FIG. 4 and FIG. (Or a convex shape).

  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 cloth or the like is laminated on at least the outer surface (upper surface 1f in FIG. 3) of the folded paper 1 to increase the strength. At the same time, the texture of the binding tool may be made to look like a desired material, or decoration may be given by printing such as coloring, patterns, and characters.

  The present invention is as described above, and a paper ring-shaped binding tool having the same function and performance as a plastic or metal ring-shaped binding tool can be provided by using only paper and an adhesive. When used as a means for binding a large number of sheets such as a calendar, there is an advantage that it can be disposed as it is without being separated from the node main body or the calendar main body after use.

  In addition, since the binding tool of the present invention can be produced with only paper and an adhesive, it is advantageous in terms of material cost compared to a plastic or metal binding tool, and the manufacturing machine has a simple mechanism. Therefore, it is advantageous in terms of material cost and equipment.
