Description

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

  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 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 this point of view, for example, a calendar binding technique that does not use any metal binding tool for calendars has been proposed as Japanese Patent No. 3243152. 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 configuration of the manufacturing method of the binding tool of the present invention, which has been made for the purpose of solving the above problems, is to fold and bond a sheet with an adhesive on the facing surface, or to bond the facing surface of at least two sheets. Adhesive is attached to the laminate, and before the adhesive is solidified, the bonded paper is cut into a substantially comb-like shape and then rolled into a cylindrical shape. bending both end portions in the form of butt seam on the outside of the tubular, by solidifying the sheet by drying the adhesive in this state, a cylindrical comb-like portion including the both end portions are solidified it is characterized in that formed so as the elastic by openable ring-shaped sheet.

The configuration of the binding tool of the present invention formed by the above-described manufacturing method is such that a sheet with an adhesive on the opposite surface is folded in two or bonded, or an adhesive is attached to the opposite surface of at least two sheets and laminated. The rectangular paper sheet is cut into a comb-like shape, leaving room on one end thereof, and formed into a cylindrical shape , and the adhesive is dried to solidify into the cylindrical shape , and the solidified cylindrical paper by forming the both end portions to form the twofold folded toward the outside of the tubular, the tubular portion including opposite ends and the comb teeth of the rafter is formed on the openable ring with elastic It is characterized by.

  In the binding tool of the present invention using double-bonded paper, when a single paper is folded in two, it is possible to adopt a configuration in which a paper string or the like as a core is sandwiched inside the fold. 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.

  Next, the binding tool of the present invention may have a structure in which a rough cloth or nonwoven fabric or thin Japanese paper is laminated on the outer surface of the paper or the application surface of the adhesive. 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 performed on the outer surface of the paper or cloth or the outer surface of the folded paper. Furthermore, although the paper is subjected to waterproofing or moisture-proofing, the finished binding device of the present invention may be waterproofed or moisture-proofed.

  In the present invention, if vegetable glue or animal glue is used as the adhesive applied to the paper, the binding tool body and the material used for the present invention are all natural materials up to the adhesive. It is desirable from the viewpoint of conservation.

  In the present invention, since a sheet binding device bound to a notebook, a calendar, or the like is formed using only paper or an adhesive made of paper and a natural material, a used notebook, a calendar, or the like is used as a constituent member thereof. Without sorting, it can be sent to the whole process as it is.

  Next, a description will be given of an embodiment of a binding tool formed using double-bonded paper among the binding tools of the present invention with reference to the drawings. FIG. 1 is a perspective view of a relatively thick quadrilateral sheet forming the ring-shaped binding tool of the present invention, FIG. 2 is a perspective view of a state in which the sheet of FIG. 1 is folded and adhered, and FIG. 4 is a perspective view of the paper sheet cut into a substantially comb-like shape. FIG. 4 is a diagram of the substantially comb-like paper sheet of FIG. 3 rolled into a cylindrical shape and bent into a shape in which both ends of the rounded cylindrical shape are joined. FIG. 5 is an AA arrow enlarged cross-sectional view (end surface) of FIG. 4.

  The illustrated binding tool of the present invention is, for example, a rectangular paper 1 (hereinafter simply referred to as “paper”) having a rectangular shape with a width of about 4 to 6 cm and a length of about 5 to 7 cm (for example, about 0.2 to 0.5 mm). Formed). 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, the grooves 4 are formed (cut) at equal pitches on the side of the two-folded paper 1 where there is no crease 3 by a press blade or the like. The whole is formed in a substantially comb-like shape, leaving the tooth portion 5 in the shape (see FIG. 3). In the present invention, the number of grooves 4 (the number of tooth portions 5) can be arbitrarily set depending on the balance between the size of the paper 1 and the width of the groove 4 to be cut (the remaining tooth portions 5).

  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. Moreover, although a cylindrical outer diameter is also arbitrary, about 5.6-15 mm is a preferable example.

  In the present invention, following the cylindrical forming of the paper 1, the outer end portion (the side of the bent portion and the opposite side) forming the length of the cylindrical body is bent outward from each other and bent. Formed in the palm portions 6a and 6b in a shape where the portions are joined.

  Here, when the paper 1 of FIG. 3 is rolled and formed in a shape in which both outer side portions of the cylinder are folded to the outside, the folded paper 1 is still in a state where the adhesive 2 is not solidified. From the circumferential length difference that occurs at the inner and outer surfaces of the cylinder during the cylindrical molding and folding of the joints 6a and 6b depending on the thickness of the paper 1, the inner side (lower 1u in FIG. 3) of the paper 1 A deviation F occurs between the leading edge and the leading edge of the paper 1 on the outside (upper side 1f in FIG. 3). Since the adhesive 2 is solidified by forced drying in the state in which the deviation F is generated, the folded paper 1 formed into a shape in which the both ends are formed as shown in FIGS. It will solidify in that state without returning.

  Each tooth part 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 forming of the joints 6a and 6b and the solidifying action of the adhesive 2 is as if it were made of plastic or metal. It can be used as a ring-shaped binding tool as an openable / closable ring body that exhibits sufficient springiness (elasticity) similar to that of the ring.

  In the present invention, by selecting the thickness and size of the paper 1 to be used, the ring-shaped binding 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. A tool 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.

  Further, when a paper string, for example, is inserted into 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 is increased. 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, a concave mold 7 (see FIG. 4 and FIG. 5 for assisting the opening of the ring). (Or a convex shape). Further, after binding sheets such as a calendar using the binding tool of the present invention, the joint portions 6a and 6b may be bonded to each other.

  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. Further, the finished binding tool of the present invention may be waterproofed or moisture-proofed.

  The above is an example in which a sheet of quadrilateral paper 1 is folded in two with an adhesive in between, or a paper in which at least two sheets of paper are bonded and laminated is formed on the binding tool of the present invention. However, the binding tool of the present invention is not limited to be folded and doubled, and even if one sheet is a sheet having sufficient hardness, strength, and elasticity (spring property), the present invention is a single square sheet. The ring-shaped paper binding tool can be formed. The same components as those in the above example can be added to the paper of the paper binding tool.

  In the binding tool of the present invention using one sheet of the above-mentioned hardness, strength and elasticity (spring property), each step of applying an adhesive, folding, and stacking is performed as compared with the manufacture of a binding tool using a double sheet. Is unnecessary, and it is not necessary to perform cutting and folding before drying the adhesive.

  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 particular, in the binding tool of the present invention, since the both ends of the ring body that can be freely opened and closed by the elasticity of the paper are formed in the shape of a palm, for example, when this binding tool is used as a ring binding tool such as a calendar or a notebook, An end portion of the ring body to be opened and closed can be sandwiched between the sheets as a palm surface facing in the same direction as the surface of the sheet such as a calendar or a notebook bound to the binding tool. In addition, the opening and closing part (gap part) of the ring body in the binding tool of the present invention is not exposed at all to the outside of the calendar, notebook, etc., which has the advantage of improving the appearance of the calendar or notebook. is there.
By the way, if the palm portion is not formed on the comb-shaped paper, the opening / closing part of the ring body is oriented perpendicular to the sheet to be bound, so this part is located on the outermost side of the sheet to be bound. Since it must be positioned on the sheet of paper, it is not preferable in appearance, and when the sheet that is bound with this binding tool is turned over, the turned-up sheet is the palm portion. There is a problem that the entire sheet including the binding tool is not flattened by being caught on the portion not formed on the sheet.

  Furthermore, since the binding tool of the present invention can be produced with only hard and strong elastic paper, or with only a little thick paper and adhesive, the material cost is lower than that of plastic or metal binding tools. This is also advantageous in terms of material, and the manufacturing machine for manufacturing is sufficient with a simple mechanism, which is advantageous in terms of material cost and equipment.
