Description

  The present invention relates to a booklet manufactured by binding a plurality of paper sheets using a paper binding tool, and more particularly to a booklet using a paper binding tool in consideration of safety during use.

  As a means for binding booklets such as calendars and notebooks, metal binding metal fittings formed in a spiral or ring shape have been widely used. However, since metal binding metal fittings cannot be incinerated, these booklets When disposing of the booklet, it is necessary to remove and separate the binding hardware from the paper booklet body, which is very complicated, and as a combustible waste without removing the binding hardware from the booklet body.

  The paper binding tools disclosed in Patent Document 1 and Patent Document 2 are obtained by folding and stacking rectangular thick paper in two, with a predetermined range from the side of the fold as the base, and other than the base By forming a large number of groove-shaped cuts at equal intervals in the part, a large number of comb teeth protruding in the direction perpendicular to the longitudinal direction of the base are formed, and each of these comb teeth is rounded into a ring shape. Manufactured.

  This paper binding tool is manufactured in a state in which a large number (for example, 50 to 100) of ring-shaped comb teeth portions are adjacent to each other at equal intervals on one side of the elongated belt-like base portion. When a booklet is manufactured using a binding tool, first, the paper binding tool is cut into an appropriate length (for example, a length corresponding to three comb teeth portions). Then, as shown in FIG. 2, the distal end portion 23 of the comb-tooth portion 22 of the cut paper binding tool 21 is passed through the binding hole 12 of the paper sheet 11 that is overlapped, and the distal end portion 23 is inserted into the base portion 24. Adhere to.

  The booklet manufactured in this way has the following problems. When the paper binding tool 21 is cut, it is simply cut by a press blade or the like, so that the corner 24a of the base 24 becomes sharp, and there is a risk of injury to fingers or the like when handled by the user. is there.

  The present invention has been made to solve the above-described conventional problems, and an object of the present invention is to provide a booklet using a paper binding tool in consideration of safety during use.

  A booklet using the paper binding tool according to the present invention includes a plurality of paper binding tools formed by a long band-shaped base and a plurality of ring-shaped comb teeth protruding in a direction perpendicular to the longitudinal direction of the base. It is formed by binding paper sheets, and is characterized in that a corner portion of a base portion has an arc shape or is chamfered in an oblique direction.

  The booklet using the paper binding tool according to the present invention has a sharp corner at the base of the paper binding tool so that it can suitably avoid accidents such as injuries during handling and should be used safely. Can do.

FIG. 1 is a partially enlarged perspective view of a booklet using a paper binding tool according to the present invention. FIG. 2 is a partially enlarged perspective view of a booklet using a conventional paper binding tool.

  Hereinafter, embodiments of a booklet using a paper binding tool according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partially enlarged perspective view of a booklet using a paper binding tool according to the present invention. As in the conventional booklet, this booklet is a stack of a plurality of tips 3 of the comb teeth 2 of the paper binding tool 1 cut to an appropriate length (length corresponding to three comb teeth 2). It is manufactured by passing through the binding holes 12 of the combined paper sheets 11 and adhering the tip 3 to the base 4.

  In this booklet, the corner portion 4a of the paper binding tool 1 is cut into an arc shape, and the corner portion is not sharp like the conventional booklet described above, and it is preferable to avoid accidents such as injury. Can be used safely.

  In the present embodiment, the corner 4a is cut in an arc shape, but the end of the corner may be cut in an oblique direction to be chamfered.
