And, in near operating portion 44a lower edge portion the zone, the forniciform slit 44r that formation is cut continuously from the lower limb two ends of operating portion 44a, the stress decentralized institution of the stress that is produced when this slit 44r is operated as the 44a of scatter operation portion, thereby, the stress that can the 44a of scatter operation portion produces during operation can prevent the premature breakage of operating portion 44a effectively.

Especially, trunk 4 is to be made of the material with flexible, so utilize the elasticity or the flexible of this material, make recessed folding part have elasticity, can carry out strain, thereby, can utilize elastic-restoring force that operating portion 44a is placed in the peristome 44s simply as required, can make outward appearance good.

In addition, the invention is not restricted to the form of implementation described in detail above.

For example, as existing product, box type file also can be suitably to bend the unlimited case shape article in top that form along the expansion plate that the expanded view of regulation is cut off.

And variant part is not limited to be the recessed folding part of a straight line, also can be in the regulation zone of the bottom of operating portion forms a plurality of flanging portion along short transverse.And in this case, each flanging portion can alternately form protruding broken line and recessed broken line on short transverse.

Self-evident, as long as the stress decentralized institution can suitably disperse the stress that the time produces when operation just passable, be not limited to forniciform slit in the near zone of the bottom of operating portion.

And box type file is not limited to be made of the synthetic resin material, for example, also can be made of millboard or boxboard.

Under the state of operating position in peristome, be formed between edge of opening portion and the operating portion 44a gap size so long as suitably the instrument size that can enter get final product.Like this, instrument can be inserted in the gap, operating portion be started in the outer surface side of box type file.

In addition, the concrete structure of various piece also is not limited to above-mentioned form of implementation.Can in the scope that does not break away from purport of the present invention, carry out various changes.

Illustrated the present invention above adopting, with prior art with pointing the knot of catching handle hole to pull out Structure is compared, and can control operating portion and pull out simply box type file. At this moment, owing to will not point Be inserted in the accommodation space, so even be received in the situation in the accommodation space will being contained thing, The finger and be contained also not mutually mutual interference of thing, easy to use, practical. And, utilize the section of cutting The row traction can be lived in finger grip as before in the position, and is extremely convenient.
