Description

The present invention is a file having a holding portion for holding an object to be held such as a document, the holding portion being attached to a cover, and the object held in the holding portion being released from the pocket. for files formatted to prevent

A conventional file with a pocket fixed to the cover has an opening on one side with a thin synthetic resin sheet, as disclosed in Japanese Patent Application Laid-Open Nos. 5-177970 and 2004-216595. A square bag body having a cover is formed, and the bag body is fixed to a cover made of synthetic resin by thermal welding or ultrasonic welding.

JP-A-5-177970 JP 2004-216595 A

The file holding portion according to the invention described in Patent Document 1 is composed of a rectangular bag having an opening formed at one end and a closed portion formed at the other end, and the cover and the bag form the opening of the bag. Pockets, which are two adjacent holding portions each having an opening at one end, are formed through the welded portions by welding continuously from approximately the center of the side forming the portion in a direction orthogonal to the side. be done.

The file is welded over substantially the entire length of the bag to form a boundary line between two adjacent pockets. If the distance to the closed end at the opposite position is close to this, when an object is put in from the opening, the object to be held will resist the frictional force generated between the object to be held and the inner surface of the pocket. Attempting to carry out the action because it is necessary to push the object toward the bottom edge of the pocket, and the movement of the object is allowed only in a substantially straight direction from the opening edge to the bottom edge. A person (user) is required to perform an accurate operation, and in particular, if the object to be held is soft such as a piece of paper, the object to be held may be bent if the object is not operated accurately.

The file according to the invention described in Patent Document 2 does not weld the vicinity of the opening when fixing the bag to the cover, that is, provides an unclosed portion between two adjacent pockets in the vicinity of the opening. As a result, for example, a portion near the boundary line of the opening of the first pocket can serve as the opening of the second pocket adjacent to the first pocket, so that the opening is slightly larger than the width of the pocket. , immediately after the object to be held, which has a width close to the width of the pocket, is pushed toward the bottom end of the pocket, the object is pushed in a substantially straight direction from the opening side end to the bottom end. Since movement in directions other than the above is permitted to some extent, workability is slightly improved compared to the file according to the invention described in Patent Document 1.

In this way, in the case of the conventional file in which the pocket is fixed to the cover, the size of the object to be held and the pocket are not significantly different, and the contact area between the two when the object to be held is stored in the pocket is large. As a result, the frictional force between the object to be held and the inner surface of the pocket is relatively large. It is assumed that an external force must be applied by the user to push it toward the closed end). It can be said that it is assumed that an external force must be applied by the user to pull out the held object from the pocket.

However, such a file relies only on the frictional force between the objects to maintain the state in which the object is held in the pocket. When the pocket is held in a low position, or when the contact area between the object and the pocket is small due to air entering between them, if the opening of the pocket is directed toward the center of the earth, , the object to be held may fall out of the pocket through the opening due to a force that exceeds the frictional force between the object to be held and the inner surface of the pocket due to the gravity of the earth.

In addition, the items held in such a file and the pocket of the file do not necessarily have to be the same size or close to it. There is no special reason to exclude the case where a small object is selected as an object to be held, and when such an object is stored in a pocket, the contact area between the object and the pocket is small. , so that the frictional force between the object to be held and the inner surface of the pocket is small, so that even when the opening of such a pocket is turned toward the center of the earth, the object to be held also leaves when the pocket is shaken. Objects easily fall out of pockets.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a file in which a pocket is fixed to a cover so that an object held in the pocket is not easily separated from the pocket.

According to a first aspect of the present invention, there is provided a file comprising a cover body and a bag-shaped pocket attached to the cover body, the cover body having a fixing portion for attaching the pocket, and the pocket. is a file having a fastener at one end and a fixed part fixed to the fixing part.

The invention according to claim 2 is the file according to claim 1, wherein the fixed portion is provided at an end portion of the pocket and at a position facing the one end portion.

The invention according to claim 3 is characterized in that the cover body is formed by connecting a first cover sheet and a second cover sheet, and the fixing part is provided on the first cover sheet. It is the file described.

In the invention according to claim 4, the cover body comprises a first cover and a second cover, and the fixed part is provided on each of the first cover and the second cover. Or the file according to claim 2.

The invention according to claim 5 is characterized in that the cover body comprises a first cover, a back cover, and a second cover, and the fixed part is provided on the back cover. It is the file described in 2.

According to a sixth aspect of the present invention, both the cover body and the pocket body are made of a synthetic resin material, and the fixed portion and the fixed portion are fixed by welding. It is a file described in either.

According to the present invention, in a file in which a pocket is fixed to a cover, a fastener provided at one end of the pocket is opened to store an object to be held, and the object can be easily removed from the opening thus formed. To provide a file in which an object to be held can be put in a pocket and the object to be held held in the pocket is not easily separated from the pocket by closing the opening to form a closed part. can.

By forming the closure part, the closure part is centered on the earth because it does not rely only on the frictional force between the two to maintain the state in which the object to be held is stored in the pocket as in the conventional file. Even if the object to be held receives a force exceeding the frictional force between the object to be held and the inner surface of the pocket due to the gravity of the earth, the closing part prevents the object from moving out of the pocket. Therefore, it does not fall out of the pocket through the closing part.
