Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calender, and more particularly to a calender consisting entirely of paper members.

[0002]

2. Description of the Related Art In recent years, environmentally friendly and resource saving have been sought, and a calendar made entirely of paper members has come to be used without using binding members such as metal fittings and plastics. Came. These calendars are disclosed in Japanese Utility Model Publication No. 6-36865 and Utility Model Registration No. 300.
1182 publication is mentioned. These are backing sheets that are folded in half as interleaving paper pieces obtained by stacking individual calendars, forming binding holes along the upper side of the interleaving paper pieces at predetermined intervals, and pouring an adhesive material into the binding holes. Are to be stuck together. Japanese Utility Model Laid-Open No. 6-36865 provides a void portion above the binding hole of the spine mount, and Utility Model Registration No. 3001182 has a groove recessed from the inside to the outside along the lower side below the binding hole. To form.
However, in the above-mentioned conventional techniques, there are cases where the strength against bending is not sufficient. In addition, if the paper thickness is increased in order to increase the strength, it is difficult to process the spine mount.

[0003]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an environment-friendly calendar with a back mount having an appropriate thickness that is strong against bending of the calendar from side to side and has good designability. The challenge is also to provide a good calendar.

[0004]

SUMMARY OF THE INVENTION According to the present invention, holes are formed at predetermined intervals along the upper side of an interleaving paper sheet obtained by stacking a plurality of calender paper sheets, the holes are filled with an adhesive, and the sheet is folded in two. A calendar in which the upper side portion of the interleaving paper piece is sandwiched and stuck by the back mount paper, and a plurality of recesses are provided below at least one of both sides of the bi-folded back mount paper. Also,
In the calendar, the plurality of recesses have a plurality of shapes.

[0005]

Function: A hole penetrating the interleaving paper piece is opened, and the hole is filled with an adhesive, so that the adhesive area is increased, and after the adhesive is solidified, it is formed into a columnar shape, so that the binding is strong. In addition, since a plurality of recesses are provided below at least one of the both sides of the back mount, the shape of the embossing is sharpened compared to the case where a single groove is provided, and the strength against bending to the left and right is increased. Out. Further, since the recesses are not adhered to the interleaving paper with an adhesive, it is better to divide the recesses into a plurality of grooves than to form one groove, because the recesses also adhere to each other, so that the strength is increased. further,
By using a plurality of arrangements of a plurality of recesses and a plurality of shapes of the plurality of recesses, it is possible to obtain a calendar having a spine mount excellent in design.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. <Embodiment 1> FIG. 1 is a perspective view of a calendar showing an embodiment of the present invention. The interleaving paper piece 1 is provided with holes 2 penetrating at a predetermined interval along the upper side of the interleaving paper piece 1 in which a plurality of calender paper pieces are superposed, the adhesive 5 is filled in the holes, and the back mount paper 3 folded in two is used. The upper side part was sandwiched and pasted. As the adhesive 5, a commercially available hot-melt type adhesive was used. The hole 6 is used for hanging. At this time, a concave portion 4 that is convex from the inside to the outside is provided below the front side of the interleaf sheet 1 that is folded in two. 2 is the X of FIG.
It is a -X cross-section explanatory drawing. This calender has improved strength against bending in the left-right direction as compared with a calender having no concave portion 4 or a calender having one concave groove.

<Second Embodiment> FIGS. 3 and 4 are perspective views showing another embodiment of the present invention. The interleaving paper piece 1 is formed by arranging holes 2 penetrating at a predetermined interval along the upper side of the interleaving paper piece 1 in which a plurality of calender paper pieces are superposed, filling the holes with an adhesive 5, and folding the backing paper 3 in half. The upper side part was sandwiched and pasted. As the adhesive 5, a commercially available hot-melt type adhesive was used. At this time, the interleaf sheet 1 folded in two
A concave portion 4 that is convex from the inside to the outside is provided below the front side of the. As the concave portion 4, a combination of the same shape but different direction (FIG. 3) and the different shape (FIG. 4) was used. These calenders have improved strength against bending in the left-right direction as compared with a calender having no concave portion 4 or a calender having one concave groove.

[0008]

According to the present invention, since it is made entirely of paper members, it is environmentally friendly, and since a plurality of recesses or a plurality of recesses having different shapes are provided on the backing paper, a calendar having sufficient strength against left and right bending. I was able to get Since there are a plurality of recesses, the recesses can be formed more clearly than one groove. Further, by forming a plurality of concave portions or a plurality of concave portions having different shapes, a calendar excellent in design is obtained.
