<First Embodiment>
Hereinafter, a preferred first embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the present embodiment, a case where a file according to the present invention is applied to a clear file will be described as an example. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  In the clear file 10 according to the present embodiment, a flexible sheet body 120 made of a plastic material such as polypropylene or hard vinyl chloride is bent at a central portion 122 in the longitudinal direction, and the sheet on one side with the central portion 122 as a boundary. The portion 124a and the sheet portion 124b on the other side are overlapped to form a rectangle as shown in FIG.

  At both ends in the longitudinal direction of the rectangular clear file 10, there are formed welded portions 142 in which the folded sheet portions 124a and 124b are welded to each other by thermal welding or ultrasonic welding. As a result, the clear file 10 can be opened at one peripheral edge, specifically, the end opposite to the central portion 122 that is one short end (left side in FIG. 1), in other words, the sheet portions 124a and 124b. Can be separated. Hereinafter, the open part is referred to as an open part 126. The clear file 10 can accommodate objects such as documents and notes between the opening portion 126 and the sheet portions 124a and 124b. For the sake of explanation, the end facing the central portion 122 will be referred to as the left end and will be described below. Note that a notch 160 for facilitating the opening of the opening 126 is formed in the sheet portion 124a on one side in the vicinity of both ends in the longitudinal direction of the clear file 10.

  The sheet portion 124b is formed with an extending portion 128 whose left end extends from the left end of the sheet portion 124a. Therefore, the edge of the opening 126 extends from the left end edge of the sheet portion 124a. It is formed by the left end edge of the part 128. In the clear file 10 according to the present embodiment, a blocking piece 180 that can block a part of the opening portion 126 is provided in the extending portion 128.

  The closing piece 180 has a flexible sheet shape, and is integrally formed with the sheet portion 124b in this embodiment. The closing piece 180 is folded back to the inner side of the clear file 10, that is, the sheet portion 124 a side, and a welded portion 144 is formed on the left end portion and the extended portion 128 by heat welding or ultrasonic welding. The folded state is maintained. In this state, the closing piece 180 is in contact with the outside of the sheet portion 124a and the inside of the sheet portion 124b. By inserting the left end portion of the sheet portion 124a between the closing piece 180 and the sheet portion 124b, the left end portion of the sheet portion 124a is formed between the sheet portion 124b and the closing piece 180 as shown in FIG. Since the closing piece 180 is bent by this, the left end portion of the sheet portion 124a can be urged toward the sheet portion 124b by the repulsive force.

  In this state, the closing piece 180 can close a part of the opening portion 126, that is, substantially the center in the present embodiment, and can prevent the stored contents from falling off. Furthermore, when the urging is generated, the closing piece 180 can sandwich the left end portion of the sheet portion 124a between the closing portion 180 and the opening portion 126 can be closed with an appropriate force. . Since the closed state can be easily released by bending the other end portion (right end portion) of the closing piece 180 away from the seat portion 124a, the open portion is opened and closed using, for example, a wire fastener. Compared with an existing file, the opening part 126 can be opened and closed very easily. In addition, it is possible to easily determine visually whether or not the opening part 126 is closed as compared with the existing file.

  According to the clear file 10 described above, the occlusion piece 180 that closes the opening portion 126 can prevent the contents from falling off while suppressing a decrease in the capacity of the clear file 10. In addition, since the extending portion 128 is formed in the sheet portion 124b and the closing piece 180 is fixed thereto, the accommodation capacity of the clear file 10 can be maintained.

  Further, even if the stored item moves to the opening portion 126 side when the clear file 10 is dropped or transported, the stored item comes into contact with the fixing portion of the closing piece 180, and the closing piece 180 is separated from the sheet portion 124a. Since it is difficult for stress to be applied in the direction to be removed, the drop-off prevention function can be made more reliable. Further, the left end of the sheet portion 124a is urged so that the closing piece 180 sandwiches the left end of the sheet portion 124b. The urging force can be applied to the accommodation moved to the 126 side, and the unintentional opening of the closing piece 180 and the movement of the accommodation can be suppressed.

  Further, since the closing piece 180 biases the left end portion of the sheet portion 124a, the opening portion 126 can be kept closed without using fasteners such as Velcro (registered trademark) and buttons. Furthermore, since the number of manufacturing steps is reduced by the configuration as described above, it can be manufactured very easily and at low cost.

  In the present embodiment described above, it has been described that the closing piece 180 is provided integrally with the sheet portion 124b. However, the closing piece 180 may be provided separately on the sheet portion 124b. This also applies to the sheet portions 124a and 124b. For example, two sheets having different colors, surface treatments, members, and the like may be connected by welding or the like to form the sheet body 120.

  Moreover, about this embodiment, although the obstruction piece 180 was welded in the extension part 128, it is not limited to this. The closing piece 180 only needs to be provided at the peripheral edge portion so that at least the opening portion 126 can be closed. For example, the closing piece 180 may be simply bent so as to be positioned on the sheet portion 124a without providing the extending portion 128. Although the urging force is not generated, the opening 126 can be closed. In addition, if the closing piece 180 is attached as a separate body, for example, it is fixed to the outer surface of the sheet portion 124b (the surface not facing the sheet portion 124a) and is bent into a V or U shape, thereby opening the opening portion. 126 can be occluded.

  In the present embodiment, one closing piece 180 is provided corresponding to one opening portion 126, but the present invention is not limited to this, and naturally a plurality of closing pieces 180 are provided corresponding to one opening portion 126. It may be. If at least a part of the opening 126 is closed, it is possible to prevent the fall of the contents. Further, the length of the closing piece 180 in the longitudinal direction of the clear file 10 does not have to be the length reaching the vicinity of the two notches 160 as shown in FIG. What is necessary is just to set suitably according to 120 materials, a use, a design, etc.

  In the present embodiment, it has been described that both ends in the longitudinal direction of the sheet main body 120 are fixed by forming the welded portion 144, but only one end of the sheet main body is fixed and the other end is fixed. You may apply this invention to the clear file in which the further open part was formed in the part. In the clear file 10 a shown in FIG. 3, an extension portion 128 is formed also at one end portion in the longitudinal direction of the sheet main body 120, a welding portion 144 is formed in the extension portion 128, and a closing piece 180 is welded. Thereby, it is possible to prevent the stored items from falling from the two open portions 126. In addition, it goes without saying that the present invention can be applied to various types of files as long as the files can be stored, and may be used for files with gussets.

<Second Embodiment>
In the first embodiment described above, it has been described that the closing piece 180 is positioned on the sheet portion 124a and the opening portion 126 is closed by the urging force thereof. However, the sheet portion 124a and the closing piece 180 may be engaged with each other so that the unintended opening of the closing piece 180 can be reliably prevented. Hereinafter, the clear file according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 4, the clear file 10b according to the present embodiment is related to the first embodiment in that a slit 200a extending in the longitudinal direction is formed at the left end of the sheet portion 124a. Different from clear file 10. By inserting the leading end 182 of the closing piece 180 into the slit 200a along the right direction in the figure, the sheet portion 124a and the closing piece 180 are engaged. Thereby, since the front end 182 of the closing piece 180 is located inside the sheet portion 124a, the closing of the opening 126 can be strengthened and the unintentional closing piece that the front end 182 of the closing piece 180 is caught. Opening of 180 can be reliably prevented. In addition, it is preferable to provide a circular hole at both ends of the slit 200a to prevent tearing.

<Third Embodiment>
In the above-described second embodiment, the slit 200a is provided in the sheet portion 124a and the closing piece 180 is inserted, but the closing portion 180 is provided with a return so that the sheet portion 124a and the closing piece 180 are engaged. May be. Hereinafter, the clear file according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 5, in the clear file 10c according to the present embodiment, a slit 200b is formed instead of the slit 200a at the left end portion of the sheet portion 124a, and a slit 300a and a return portion 302a are formed in the closing piece 180. In that it differs from the clear file 10b according to the second embodiment.

  The slit 300a has a semicircular shape that curves in the left direction, whereby a return portion 302a having the same shape is formed. When the opening portion 126 is closed by the closing piece 180, the return portion 302a is inserted into the slit 200b along the left direction in FIG. 5 to return the return portion in the opposite direction to the clear file 10b according to the second embodiment. 302a is inserted. Therefore, the movement of the closing piece 180 in the left direction in the figure can be restricted. Accordingly, it is possible to firmly close the opening portion 126 and to reliably prevent the unintentional opening of the closing piece 180. As with the slit 200b, it is preferable to provide circular holes at both ends of the slit 300a to prevent tearing due to stress concentration.

<Fourth Embodiment>
In the above-described third embodiment, the return portion 302a is simply inserted into the slit 200b, but the return portion of the closing piece 180 is hooked on the slit of the sheet portion 124a, and these are firmly engaged. Also good. Hereinafter, the clear file according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 6, in the clear file 10d according to the present embodiment, a slit 200c is formed instead of the slit 200b at the left end portion of the sheet portion 124a, and the slit piece 300a and the return portion 302a are replaced with the closing piece 180. It differs from the clear file 10c according to the third embodiment in that the slit 300b and the return portion 302b are formed.

  In the present embodiment, since the return portion 302b is hooked on the slit 200c, the stress applied to both ends of the slit 200c is larger than that of the slits 200a and 200b described above. Therefore, the slit 200c according to the present embodiment is formed in a long hole shape having a width in the left-right direction in FIG. 6 in order to further relax the stress concentration, and has a large round shape at both ends thereof. Moreover, the return part 302b can be easily inserted by forming the slit 200c into a hole shape.

  The slit 300b has a semicircular shape that curves in the left direction like the slit 300a described above, but the curved portions 304b that are greatly curved are formed at both ends to realize higher stress relaxation than the slit 300a. ing. When the opening portion 126 is closed by the closing piece 180, the return portion 302b is inserted into the slit 200c in the left direction in FIG. 6, so that the rounded portion 304b of the return portion 302b contacts the left edge of the slit 200c in the drawing. . Further, in a state where the sheet portion 124a and the closing piece 180 are not engaged with each other, the slit 300b is formed so that the right end portion in FIG. 6 of the round portion 304b is positioned slightly to the left of the left edge in the drawing of the slit 200c. ing. Thus, the tension between the sheet portion 124a and the closing piece 180 in the state where the sheet portion 124a and the closing piece 180 are engaged, that is, the rounded portion 304b of the return portion 302b is in contact with the left edge of the slit 200c in the drawing. Will occur. Thereby, the engagement between the seat portion 124a and the closing piece 180 can be made stronger, and the unintended opening of the closing piece 180 can be reliably prevented.

  Needless to say, slits 200a and 200b may be provided instead of the slit 200c. The same applies to the clear files 10b and 10c according to the second and third embodiments.
