SUMMARY OF THE INVENTION In order to solve this problem, the present invention relates to a holder for storing a document or the like in which a storage portion for a document or the like is formed by a sheet made of synthetic resin, and has a rectangular planar shape. And an infinite number of spot-shaped fused portions are formed along one side of the storage holder, and file means are formed at appropriate intervals along the one side within the range of the spot-shaped fused portion. The gist of the present invention is that at least one of the remaining three sides of the storage holder is provided with an opening through which a document or the like is inserted into or removed from the storage section for the document or the like. Further, according to the present invention, the synthetic resin sheet forming the storage holder is folded back on one side of the storage holder to have a three-layer structure or more, and a spot-like fusion part is formed on the three-layer structure or more. The point is to become. In addition, the present invention provides that all spot-shaped fused portions are formed so that the density of all the spot-shaped fused portions is in the range of 30 to 75% with respect to the area of the reinforcing portion formed by the spot-shaped fused portions. It is assumed that. Further, the present invention is characterized in that the spot-shaped fused portion is formed by ultrasonic fusion, heat fusion, or a combination of ultrasonic fusion and heat fusion. Furthermore, the present invention
The gist is that the file means is a locking portion cut into a substantially T shape.

According to this structure, since numerous spot-like fusion parts are formed along one side of the storage holder in which the file means is formed, the file means is reinforced. Compared with the case of interposing a reinforcing synthetic resin tape as in the conventional example, the formation of the file means can be easily reinforced and the cost can be reduced.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment will be described with reference to FIGS. 1 to 4. Reference numeral 11 denotes a document storage holder in which a document storage unit 14 is formed by two sheets 12 and 13 made of synthetic resin. The planar shape is rectangular, and countless spot-like fusion parts 15 are formed along one side of the document storage holder 11 by ultrasonic fusion. Specifically, at one side of the document storage holder 11, the end of the synthetic resin sheet 12 and / or 13 forming the document storage holder 11 is folded back to 3.
A spot-like fusion part 15 is formed in a portion of the three-layer or four-layer structure. A locking portion 16 cut in a substantially T-shape as a file means is formed at an appropriate interval along the one side within the range of the spot-shaped fused portion 15. Further, an opening 18 for inserting and removing the document 17 into and from the document storage unit 14 is formed in the upper end side of the document storage holder 11 in the upright state.

In the above construction, the locking portion 16 cut into a substantially T-shape as a file means is provided on the locking portion 20 of the locking device 20 having a circular shape and having a flange portion 19 extending outward on both sides. The plurality of document storage holders 11 are locked so as to be detachably attached (see FIG. 4). In FIG. 4, reference numeral 21 denotes a cover of the file.

As described above, the locking portion 16 of the document storage holder 11 is locked to the flange portion 19 of the locking tool 20. However, if the locking portion 16 does not have appropriate hardness, the locking portion 16 is not required. Since the stopper 16 is easily detached from the flange 19 of the stopper 20, an infinite number of spot-shaped fusion parts 15 are formed by ultrasonic fusion along the positions where the stoppers 16 are formed. Part 16
Was reinforced. The size of the spot-shaped fused portion 15 is appropriately adjusted according to the size of the document storage holder 11, the type of synthetic resin used as the material of the document storage holder 11, and the like. On the other hand, it is necessary to form the all-spot-shaped fused portion 15 so that the density of the all-spot-shaped fused portion 15 is in the range of 30 to 75% in consideration of the hardness of the reinforcing portion and the strength of the waist. It is said. If the density of all the spot-like fused portions 15 is less than 30%, the hardness of the reinforcing portion cannot be maintained, and the stiffness becomes weak. If it exceeds 75%, the reinforcing portion becomes too hard and the synthetic resin becomes too hard. There is a problem that the deterioration of the metal occurs.
In this embodiment, the document storage holder 11 is formed by using a sheet made of polypropylene as a material.

By the way, in the first embodiment described above, the locking portion 16 cut into a substantially T-shape is formed as the file means, but as in the second embodiment shown in FIG. A circular hole portion 22 is formed as a file means,
The hole 22 may be locked by a ring-shaped locking tool that can open and close the file.

Further, in the above-described embodiment, the document 17 is stored in the document storage holder 11, but other business cards and photographs may be stored. Further, the positions of the openings for taking in and out documents are not limited to those shown in the drawings, and may be appropriately determined according to the objects to be stored.

In the above description, the spot-shaped fused portion 15 is formed by ultrasonic welding, but may be formed by other means such as thermal welding. Further, the spot-shaped fusion bonding portion 15 can be formed by using both ultrasonic fusion and heat fusion. For example, when forming the spot-like fusion portion 15 by ultrasonic fusion, the frequency is set to 15
It can be adjusted in the range of KHz to 50KHz,
By being able to hit 15,000 to 50,000 times per second, the fusing speed can be arbitrarily changed. In addition, the heat fusion is performed by using a roll having an infinite number of needle-shaped protrusions on a peripheral surface thereof, by using a document storage holder 11.
Is heated to a temperature at which the sheet constituting the sheet does not completely melt, and the sheet is passed between this roll and the other roll.

Further, on one side of the document storage holder 11, a spot-like fused portion 15 is formed in a portion of a three-layer or four-layer structure in which the end of the synthetic resin sheet 12 and / or 13 is folded back. The sheet 12 made of synthetic resin
Alternatively, it is possible to form a spot-like fused portion on the portion of the two-layer structure without folding back the end of the and / or 13, and furthermore, due to the structure of the document storage holder, one side of the document storage holder can be used. It is also possible to have a five-layer structure or more, and to form a spot-like fused portion in that part.

[0014]

As described above, according to the present invention, an infinite number of spot-like fused portions are formed along one side of the storage holder in which the file means is formed. Since the reinforcing member is reinforced, the formation of the file means can be reinforced more easily and the cost can be reduced as compared with the case where the reinforcing synthetic resin tape is interposed as in the conventional example.
