Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spiral or twin-ring bound notebook cover such as a sketchbook, household account book, diary, or notebook.

[0002]

[Prior art]

 As shown in FIGS. 6 and 7, a conventional spiral or twin-ring binding cover has a plurality of binding holes 3 arranged in two rows in the longitudinal direction of the round spine 7 of the cover 1 and punched. 3 has a twin ring 9 or a spiral (not shown) supported through it, and a part of the twin ring 9 or the spiral is exposed to the outside from the round spine 7. The twin ring 9 or the spiral has many sheets of paper. 10 is mixed together.

[0003]

[Problems to be solved by the device]

 In the conventional spiral or twin-ring binding notebook cover, since the twin ring 9 and a part of the spiral are exposed to the outside as described above, the exposed portion of the twin ring 9 and the spiral are the projections on the desk, stationery, etc. There was a problem that it was easy to get caught up in, and as a result, it was easily soiled and damaged. Furthermore, since the extraordinary twin ring 9 is exposed to the outside from the round spine 7 of the cover 1 and is uneven, it is possible to put or put a seal or a title on the round spine 7 of the cover 1 for organization. There was a problem that it could not be done and the appearance of cover 1 was not good.

The present invention has been made in view of the above circumstances, and provides a spiral or twin-ring binding type notebook cover in which the twin ring is not exposed to the outside and the spine of the cover can be effectively and favorably used. Is intended.

[0005]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above object, an inner back piece is formed on the inner surface side of the spine of the cover, and a plurality of binding holes are arranged side by side in the inner back piece to support a spiral or twin ring therethrough. I am trying to let you. It is preferable that the inner back piece is formed in a bag shape with respect to the back and the plurality of binding holes are arranged in two rows so as to face each other.

[0006]

[Action]

 According to the present invention having the above structure, the inner spine in the spine of the cover supports the spiral or the twin ring through the plurality of binding holes, so that these spirals and twin rings are exposed to the outside or the spiral or twin ring is exposed. The twin ring is not exposed and no unevenness is formed between the twin ring and the spine of the cover. According to the present invention as defined in claim 2, the inner back piece is formed into a substantially bag-like shape that is strong against the spine of the cover and is not easily damaged, and each of the plurality of binding holes arranged in two rows is spiral or spiral. Since it supports the twin ring, the spiral or twin ring can be mounted in a stable state inside the spine of the cover.

[0007]

【Example】

 An embodiment of the first invention of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the spiral or twin-ring binding notebook cover sheet in this embodiment has rectangular core sheets (not shown) on the left and right sides of a rectangular front sheet 2 made of synthetic resin which constitutes the cover sheet 1, respectively. A plurality of binding holes 3 facing each other in two rows are punched in the center of the plurality of core papers, and cut portions 4 are formed near the upper and lower ends of the binding holes 3, respectively. The back sheet 5 is superposed. Therefore, the cover sheet 1 is heat-sealed at the outer peripheral edges of the front side sheet 2 and the back side sheet 5, which overlap each other, and the left and right side portions that partition the inner spine piece 6, and the edges of the outer peripheral edge are cut. Manufactured by By manufacturing the cover 1, the inner spine piece 6 is formed in a bag shape on the inner surface side of the round spine 7. A seal portion 8 is formed inside and outside the outer peripheral edge of the cover sheet 1. Other parts are the same as the conventional example.

According to the above configuration, the inner spine piece 6 hidden in the round spine 7 of the front seat 2 supports the twin ring 9 through the plurality of binding holes 3 while maintaining its strength. It is not exposed to the outside (see FIG. 1), and as a result, it is possible to reliably prevent the exposed portion of the twin ring 9 from becoming dirty or being caught by a protrusion on a desk or stationery and damaged. In addition, since the extraneous twin ring 9 is not exposed from the round spine 7 and does not become uneven, it is possible to attach and write a sticker for organizing and titles very easily, and the appearance and aesthetics of the cover sheet 1 can be improved. It is possible to remarkably arrange Further, since the inner spine piece 6 is formed in a bag shape with respect to the round spine 7 of the cover 1, the round spine 7 of the cover 1 can be reinforced.

Next, one embodiment of the second invention of the present invention will be described with reference to FIG. In the spiral or twin-ring binding type notebook cover of this embodiment, a plurality of binding holes 3 are arranged in a line in the longitudinal direction instead of integrally forming the inner spine piece 6 shown in FIG. The inner back piece 6 is formed by facing and welding the perforated inner back pieces 6 ₁ and 6 ₂ to the inner surface side of the round back 7, respectively. Other parts are similar to those of the first embodiment of the invention.

Next, an embodiment of the third invention of the present invention will be described with reference to FIG. In the spiral or twin-ring binding notebook cover of this embodiment, the back sheet 5 is divided into left and right parts, and a plurality of binding holes 3 are formed on one side of one back sheet 5 in the longitudinal direction. The back sheet 5 is heat-sealed to the back surface of one side of the cover sheet 1 to form the inner back piece 6. Other parts are the same as those in the first embodiment.

Next, an embodiment of the fourth invention of the present invention will be described with reference to FIG. The spiral or twin-ring binding type notebook cover in this embodiment is formed by forming the inner back piece 6 shown in FIG. 4 into a bag shape. Other parts are the same as those of the first embodiment.

[0012]

[Effect of device]

 As described above, according to the present invention, since the inner spine piece located inside the spine of the cover supports the spiral and the twin ring through the plurality of binding holes, the spiral and the twin ring are not exposed to the outside. . Therefore, there is a special effect that it is possible to provide a spiral or twin-ring binding type notebook cover which can effectively and satisfactorily use the spine of the cover.
