Definitions

the present invention relates to a document folder for holding a document, a business card and the like.
Document holders heretofore known typically have a rectangular shape in plan, and include a document holding portion defined by a pair of synthetic resin sheets, a reinforcement portion provided adjacent the document holding portion along one edge thereof and reinforced by a synthetic resin tape held between the pair of synthetic resin sheets, and binder engagement means including a plurality of generally T-shaped cutaway portions formed in the reinforcement portion in a properly spaced relation along the edge of the document holding portion for engagement with a document binder.
the document holding portion has an opening on a top edge thereof, as viewed when the document folder is postured vertically, through which opening a document is inserted into and taken out of the document holding portion.
the synthetic resin reinforcement tape is held between the pair of synthetic resin sheets as extending along the one edge of the document holding portion. Therefore, production of the document folder requires the steps of preparing the synthetic resin reinforcement tape and fixing the tape between the synthetic resin sheets. This leads to an increase in costs.
the present invention has the following features.
the reinforcement portion provided adjacent the document holding portion along the one edge thereof is reinforced by the multiplicity of fusion-bonded spots for reinforcement of the binder engagement means. Therefore, the reinforcement of the reinforcement portion can more easily be achieved than in the conventional case where the reinforcement is achieved by the provision of the synthetic resin tape between the synthetic resin sheets. Thus, the costs can be reduced.
FIGS. 1 to 4 illustrate a first embodiment of the present invention.
FIGS. 1 to 4 there is shown a document folder 1 having a rectangular shape in plan.
the document folder 1 has a document holding portion 4 defined by a pair of synthetic resin sheets 2 and 3, and a reinforcement portion 5 provided adjacent the document holding portion 4 along one edge thereof and reinforced by a multiplicity of ultrasonically fusion-bonded spots.
the reinforcement portion 5 has a multi-layer structure, as shown in FIG. 3, which includes a plurality of layers (e.g., three or four layers) formed by folding at least one of the edge portions of the synthetic resin sheet 2, 3 and ultrasonically spot-fusion-bonded to each other.
FIGS. 3 includes a plurality of layers (e.g., three or four layers) formed by folding at least one of the edge portions of the synthetic resin sheet 2, 3 and ultrasonically spot-fusion-bonded to each other.
a plurality of generally T-shaped cutaway engagement portions 6 are formed as binder engagement means in the reinforcement portion 5 in a properly spaced relation along the one edge of the document holding portion 4.
the document folder 1 has an opening formed along a top edge of the document holding portion 4, as viewed when the document folder 1 is postured vertically, through which opening a document 7 is inserted into and taken out of the document holding portion 4.
a document binder typically has a plurality of openable binding rings 10 each comprised of a pair of binding hooks 9, and a pair of covers 11.
the T-shaped cutaway engagement portions 6 as the binder engagement means are brought into engagement with the binding rings 10.
the reinforcement portion 5 formed with the engagement portions 6 is required to have a sufficient hardness and stiffness for prevention of disengagement of the engagement portions 6 from the binder rings 10. This is why the engagement portions 6 are formed in the reinforcement portion 5 which is reinforced by the ultrasonically fusion-bonded spots.
the size of each of the fusion-bonded spots is properly selected depending on the size of the document folder 1, the type of the synthetic resin sheet to be used for formation of the document folder 1, and the like. In order to impart the reinforcement portion 5 with a sufficient hardness and stiffness, the total area of the fusion-bonded spots should account for 30% to 75% of the area of the reinforcement portion 5.
the synthetic resin sheet for the document folder 1 is made of polypropylene.
the generally T-shaped cutaway engagement portions 6 are formed as the binder engagement means in the reinforcement portion 5.
a plurality of round holes 12 may be employed for the binder engagement means as in a second embodiment shown in FIG. 5.
the round holes 12 are also adapted to be engaged with the openable binding rings 10 of the document binder.
the document folder 1 is adapted to hold a document therein, but may be designed so as to hold business cards, photographs and the like.
the position of the opening through which a document or the like is inserted into and taken out of the document folder is not limited to that depicted in FIG. 1, but may be determined depending on the kind of an article to be held in the document folder 1.
the fusion-bonded spots in the reinforcement portion 5 are formed by the ultrasonic spot fusion method in the embodiments described above, but may be formed by a thermal spot fusion method. Further, the ultrasonic spot fusion method and the thermal spot fusion method may be used in combination for the formation of the fusion-bonded spots. Where the formation of the fusion-bonded spots is achieved by the ultrasonic spot fusion method, a frequency of 15KHz to 50KHz may be employed to apply 15,000 to 50,000 impacts per second to the folded edge portions of the synthetic resin sheet (which is formed into the reinforcement portion). By adjusting the frequency, the fusion speed can be controlled as desired.
a roll having a multiplicity of needles provided on its circumferential surface is heated up to a temperature at which the synthetic resin sheet is melted to some extent but not perfectly, and the folded edge portions of the synthetic resin sheet are passed between the roll and a counter roll.
the reinforcement portion 5 provided along the one edge of the document folder 1 has the multi-layer structure which includes three or four layers formed by folding at least one of the edge portions of the synthetic resin sheet 2, 3 and spot-fusion-bonded to each other.
the reinforcement portion 5 may have a two-layer structure which is formed simply by spot-fusion-bonding the edge portions of the synthetic resin sheet 2, 3 to each other.
the reinforcement portion 5 may have a multi-layer structure having five or more layers which are spot-fusion-bonded to each other.
the reinforcement portion 5 provided along the one edge of the document folder 1 is reinforced by the formation of the multiplicity of fusion-bonded spots, and the binder engagement means including the plurality of engagement portions (generally T-shaped cutaway engagement portions or round holes) 6 are formed in the reinforcement portion 5. Therefore, the reinforcement of the binder engagement means can more easily be achieved than in the conventional case where the reinforcement is achieved by the provision of the synthetic resin tape. Thus, the costs can be reduced.
