Abstract

PURPOSE:To widen the increase and decrease range of a binding width by a method wherein the engaging insert piece of a main cover body is bent to be inserted in the bag like part of an auxiliary cover body from an opening part while the binding parts of the main and auxiliary cover bodies are opposed to each other and, in this state, binding paper is interposed between both binding parts to be bound by a binding jig. CONSTITUTION:In use, the engaging insert piece 7 of a main cover body 15 is bent to be inserted in the bag like part 16 of an auxiliary cover body 17 from the opening part 16a thereof while the binding parts 3, 12 of the main and auxiliary cover bodies 15, 17 are mutually opposed and, in this state, binding papers 24 are interposed between the binding parts 3, 12. Subsequently, a binding string is inserted in the binding holes 8, 8 of the main cover body 15 and the binding holes 14, 14 of the auxiliary cover body 17 and both end parts of said string are fastened by binding jigs 19 to perform binding operation. When the binding papers 24 increase and the binding width thereof becomes larger than the back width dimension of a back cover 5, the engaging insert piece 17 is drawn out of the bag like part 16 of the auxiliary cover body 17 corresponding to the size of the binding width to widen the back width of the back cover 5. By this method, the increase and decrease range of the binding width can be largely set and the appearance of a binding state also becomes well.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present application relates to a cover for files such as documents, in which the binding width of the spine can be increased or decreased.

2. Description of the Related Art Conventionally, binding sections each having a binding hole are arranged in a bendable manner on each side of a front cover and a back cover made of cardboard, and a width is provided at both sides between the binding sections. A file cover is known which has a flexible back cover having long binding holes in the direction, and a binding string is inserted through each of the binding holes so that binding paper can be bound at the position of the spine cover. The file cover having this configuration has a feature that the binding width can be increased or decreased within the range of the length of the binding holes provided in the spine.

Problem to be Solved by the Invention However, according to the conventional file cover described above, when the length of the binding hole provided on the spine is shortened to the extent that it is hidden by the binding portions provided on the front and back covers, When the range of increase/decrease in the binding width is small and the binding holes are formed to be long, the binding holes become exposed on the back side as the binding width increases, and further,
Since the front cover, spine, and back cover are separated, the appearance of the book is seriously unsightly, and the binding operation is inconvenient.

The purpose of the present application is to eliminate the deficiencies of the prior art described above.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application has an inner line piece, an outer binding piece, an inner front cover, an outer front cover, a spine cover, a back cover, and an interlocking piece that are arranged in series. Glue the back sides of the inner binding piece and the outer binding piece and the back sides of the inside front cover and outer front cover of the expansion board made of cardboard, and insert the binding part, front cover, spine cover, and back cover together. The inner binding piece and the outer binding piece of the expansion plate are made of cardboard, and the inner binding piece, the inner binding piece, the outer binding piece, and the outer binding piece are connected together. A sub-cover body in which the back surfaces of the inner and outer cover pieces are bonded to each other, and the back sides of the inner cover piece and the outer cover piece face each other, forming a bag-shaped part that opens at the outer edge, and integrally forming a storage part and a storage part. It consists of
The engaging piece of the main cover body is slidably inserted into the bag-shaped portion of the sub-cover body, and the binding parts are opposed to each other, and the binding part is inserted between the binding parts through the binding hole provided therein. It is characterized by binding the bound paper with a holder, and in the above, a plurality of folding lines are arranged in parallel on the back cover closer to the spine, and a plurality of folding lines are arranged in parallel closer to the back cover of the interlocking insert. Furthermore, adhesive allowance is provided continuously on the upper and lower edges of either the inner cover piece or the outer cover piece,
The bag-shaped portion is formed by bending this adhesive margin to the back surface and gluing the other upper and lower edges to the back surface.

How it works: When using the main cover, fold the retaining piece on the main cover and
Insert the JI insert into the bag-shaped part of the sub-cover body through its opening, and make the binding parts of the main and sub-cover bodies face each other, and in this state, insert the binding paper between the two binding parts. intervene. Next, a binding operation is performed using a binding tool through the binding holes in the main cover body and the binding holes in the subcover body.

In the above, when the number of binding sheets increases and the binding width becomes larger than the spine width dimension of the spine, pull out the retaining pieces from the bag-shaped part of the sub-cover body in proportion to the size. This is to widen the distance between the stacking units facing each other.
