Abstract

A file pocket suitable for accommodating thicker documents is provided. A file body using the file pocket is provided. A sheet body 11 made of a resin film is bent at a bent portion 12, and the side opposite to the bent portion 12 is provided. In the file pocket 10 formed in a bag shape by joining the end portion and the lower end portion of the sheet body, the front side sheet 11a and the back side sheet 11b of the sheet body 11 can be separated from each other at both ends of the joined portion at the lower end portion. Part 15 was provided. Since air can enter and exit through the opening portion 15, thick documents can be smoothly taken in and out of the file pocket 10. Further, since the opening portion 15 expands according to the thickness of the document, a thick document can be inserted into the file pocket 10.

Description

  The present invention relates to a file pocket formed in a bag shape and a file using the same.

  Some file pockets are formed by folding a sheet made of a transparent material and fusing side portions and lower portions to form a bag, for example, in which documents can be stored and stored.

  However, although the conventional file pocket is suitable for accommodating several thin documents, there is a problem that it becomes difficult to smoothly put in and out the document as the document becomes thick. In addition, it is difficult to insert a thick document all the way into the file pocket, and a part of the document protrudes from the upper end of the file pocket. Therefore, there is a risk that the document may be damaged during storage of the thick document.

  Therefore, an object of the present invention is to provide a file pocket suitable for accommodating thicker documents and a file using the same.

  According to one aspect, a sheet body made of a resin film, a bent portion formed by bending the sheet body in a direction perpendicular to the upper end and lower end sides thereof, and the overlapped portion on the opposite side of the bent portion. A first joining portion that joins the end portions of the sheet body, and a second joining portion that joins the lower end portions of the stacked sheet bodies, and a part of the second joining portion There is provided a file pocket provided with an opening portion capable of separating the sheet bodies.

  According to the file pocket of the above aspect, when the document is taken in and out, air enters and exits through the opening portion provided in the second joint portion, so that a thick document can be taken in and out smoothly.

  In addition, when the document is put in the file pocket, the opening part is separated according to the thickness of the document, so that a thick document can be put deep inside the file pocket. Protrusion can be prevented.

FIG. 1 is a perspective view of a file pocket according to the embodiment. 2A is an enlarged view of the vicinity of the second joint portion of the file pocket of FIG. 1, and FIG. 2B is a cross-sectional view of the AA portion of FIG. 2A. FIG. 3 is a plan view showing a state in which a document is partially inserted into the file pocket of FIG. FIG. 4 is a perspective view of the vicinity of the opening portion when a document is inserted into the file pocket of FIG. FIG. 5 is a perspective view showing a file using the file pocket of FIG.

  Embodiments will be described below with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a file pocket according to the embodiment.

  As shown in FIG. 1, the file pocket 10 includes a sheet body 11 having a substantially rectangular shape, and the sheet body 11 is bent at a bent portion 12. Then, with the bent portion 12 as a boundary, one side of the sheet body 11 is a front side sheet 11a, and the other side is a back side sheet 11b. The sheet body 11 is formed of a film made of a transparent thermoplastic resin such as polypropylene.

  In addition, a plurality of binding holes 17 are formed in the sheet body 11 along a side parallel to the bent portion 12. Next to the binding hole 17, a first joint portion 13 is formed by welding the front side sheet 11 a and the back side sheet 11 b in a dashed line.

  The first joint portion 13 is formed in a substantially linear shape from the upper end side to the lower end side of the sheet body 11. However, an inclined portion 13 a that is inclined toward the outside of the sheet body 11 is provided on the upper end side of the first joint portion 13 so that the document can be easily introduced into the file pocket 10.

  Furthermore, the 2nd junction part 16 containing the welding part 14 which joined the front side sheet | seat 11a and the back side sheet | seat 11b in the dashed-dotted line shape is formed in the lower end part of the sheet | seat body 11. As shown in FIG. A sheet body 11 is formed in a bag shape by the second joint portion 16, the first joint portion 13, and the bent portion 12.

  In the file pocket 10 of the present embodiment, an opening portion 15 is provided at the second joint portion 16 so that the front side sheet 11a and the back side sheet 11b can be separated from each other.

  2A is an enlarged plan view of the vicinity of the second joint portion 16 of the file pocket 10 of FIG. 1, and FIG. 2B is a cross-sectional view of the AA portion of FIG. 2A.

  As shown in FIG. 2A and FIG. 2B, the opening portion 15 has both ends of the second joint portion 16, that is, a portion adjacent to the first joint portion 13 and a portion adjacent to the bent portion 12. The opening portion 15 is not formed with the one-dot chain line weld portion 14. Therefore, in the opening part 15, only the front side sheet 11a and the back side sheet 11b are overlapped, and air can pass through the front side sheet 11a and the back side sheet when a force in the direction of expanding the opening part 15 is applied. 11b is separated.

  The length of the opening portion 15 is preferably about 3 mm to 10 mm, more preferably about 8 mm, for example.

  In addition, when the length of the opening part 15 is made smaller than said range, while the air flow path will become inadequate, it will become difficult to separate the front side sheet | seat 11a and the back side sheet | seat 11b. The length of the opening portion 15 may be larger than the above range. In this case, for example, when small items other than documents such as pens and coins are put in the file pocket 10, these small items are There is a risk of falling from the opening 15.

  3 is a plan view showing a state in which the document 51 is partially inserted into the file pocket 10 of FIG. 1, and FIG. 4 is a second view when the document 51 is inserted deep into the file pocket 10 of FIG. FIG. 6 is a perspective view showing a deformation of a joining portion 16.

  As the thickness of the document 51 increases, the gap between the document 51 and the film body 11 becomes narrower. For this reason, in the file pocket not provided with the opening portion 15, when the document is taken in and out, the air enters and leaves the file pocket, and the thick document 51 becomes difficult to put in and out smoothly.

  On the other hand, in the file pocket 10 of the present embodiment, as shown by an arrow B in FIG. 3, air inside the file pocket 10 can enter and exit through the opening portion 15 provided at the bottom.

  Therefore, according to the file pocket 10 of the present embodiment, even when the thickness of the document 51 is increased, the document 51 can be smoothly put in and out of the file pocket 10.

  Further, as shown in FIG. 4, when the document 51 is inserted into the file pocket 10, the opening portion 15 opens as indicated by the white arrow according to the thickness of the document, and the front side sheet 11a and the back surface are opened. The side sheet 11b is separated.

  Thereby, even when the thickness of the document 51 is increased, the thick document 51 can be accommodated in the back of the file pocket 10 without being obstructed by the second joint portion 16, and the document 51 is prevented from protruding. it can.

  Therefore, if the file pocket 10 of the present embodiment is used, the thick document 51 can be stored without being damaged.

  As described above, according to the present embodiment, a file pocket suitable for storing thicker documents can be obtained.

  FIG. 5 is a perspective view showing a file 30 including the file pocket 10 of FIG.

  A file 30 shown in FIG. 5 includes cover sheets 31 and 32 and a spine cover 33, and a binding tool 34 is provided on the spine cover 33. A plurality of file pockets 10 are attached to the file 30 by the binding tool 34.

  Since the file 30 includes the file pocket 10 shown in FIG. 1, it is suitable for storing thick documents.
