Description

  The present invention relates to a holder for storing documents.

  Conventionally, a holder made of a transparent resin or a colored resin for filing documents called a clear holder has been widely used. You can see the information of the document inside from the outside while the transparent one is housed, and the one that is colored can be used according to the nature of the document, or you can carry it around and enjoy fashion. This type of resin holder is usually manufactured by folding a single resin sheet into two or three folds, and fixing one or two sides perpendicular to the fold line, facing the fold line and the fixed side. Two sides or one side to open are open for taking in and out documents. A thin flexible resin film may be used instead of the resin sheet.

  FIG. 13 is a perspective view showing a two-fold type holder. The holder 100 is formed by folding a single resin sheet (or film) 102 shown in a development view in FIG. 14 into two, and a side 104 orthogonal to the fold line 103 is shown in a sectional view in FIG. Manufactured by welding simultaneously with pressurization with M2. The two sides opposite to the folding line 103 and the fixed side 104 are opened for taking in and out the document.

Usually, a large number of protrusions J are formed one-dimensionally at almost equal intervals on the pressing surface of one mold M1. And since resin spreads in a surface direction with pressure welding, the recessed part between adjacent protrusions becomes escape corresponding to the expansion. As a result, in the completed holder, the protrusion 105 is formed on the fixing side 104.
In addition, printing, engraving, labeling, and the like are known as means for attaching identification information such as trademarks and models and advertisement information to the holder. A label L is attached to the holder of FIG.

However, since the main surface of the sheet (or film) is used for any of printing, marking, and labeling, it is not possible to see through the marking or label portion even if the sheet (or film) is transparent. In addition, even if a pattern is drawn on a sheet (or film), a stamp or label located in the vicinity of the pattern deteriorates the design value.
Therefore, an object of the present invention is to provide a document holder to which information is imparted without impairing the transparency and design value of the main surface of the sheet (or film).

In order to solve the problem, the document holder of the present invention is
It consists of a folded sheet or film, or a plurality of stacked sheets or films, and the opposing surfaces are partially fixed to each other to form a document storage section or a plurality of sheets Or in the case where the film is bound,
The sheet or film has at least a fixing portion made of a resin, and the fixing is performed by pressure welding the resin into a shape of a character, a figure, a symbol, or a combination thereof in a plan view of the sheet or film. Features.
According to this document holder, identification information and advertisement information can be given by the characters, figures, symbols, or combinations thereof. And since these information are originally described in the adhering part necessary for forming the document storage part or binding a plurality of sheets or films, the transparency of the main surface of the sheet or film is present. And design value is not impaired.

  Information can be given without impairing the transparency and design value of the main surface of the sheet or film.

Embodiment 1
A document holder according to a first embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view showing a two-fold type document holder, FIG. 2A is a plan view, FIG. 2B is a bottom view, and FIG. 3 is a cross-sectional view taken along line XX in FIG. FIG. 4 is a cross-sectional view showing the manufacturing process of the document holder. The development plan view of the document holder appears in the same manner as FIG.

  The document holder 1 accommodates up to 10 documents of A4 size so that they can be taken in and out quickly. The document holder 1 is manufactured as follows. First, a single transparent polypropylene sheet 2 (reference numeral 102 in FIG. 14) having an A3 size thickness of 0.1 to 1.2 mm as shown in FIG. 14 is prepared. Then, it is folded in two along the folding line 3 (103) at the center in the longitudinal direction so that the upper surface side is a mountain and the lower surface side is a valley. Next, the folded sheet 2 is attached to a fold line 3 as shown in FIG. It is placed so that one orthogonal side coincides with the protrusion row P of the lower mold F. Each protrusion in the protrusion row P is in the form of a character or a symbol. In the illustrated example, a plurality of URLs “kanbi@zero.ad.jp” are continuously engraved.

In this state, the lower mold F and the horn H are preheated by a heating element (not shown), and ultrasonic waves are applied while applying pressure to the sheet 2 via the horn H. Then, the two surfaces of the sheet 2 are welded to each other. On the fixed side 4, a projection mark 5 representing the URL “kanbi@zero.ad.jp” is formed corresponding to the projection row P.
As shown in FIGS. 1 and 2, the document holder 1 thus obtained has a folding line 3 and a welded side 4 closed, two opposite sides are opened, and there is a bag-like space between the two sides. And documents can be stored there.
The preheating is not essential, and is appropriately selected depending on the thickness of the sheet, the material, the size of the protrusion, and the like. The same applies to the following embodiments.

Since the document holder 1 is transparent, the stored document can be seen through. The projection mark 5 is originally essential for welding, and the presence of the projection mark 5 does not reduce the perspective area, and the protrusion mark 5 allows the user to obtain the URL information.
In this embodiment, a molded body made of only a transparent resin is used as the sheet 2. However, the present invention is not limited to this, and as described in the specification of utility model registration No. 3127872, one side or both sides of cardboard. Alternatively, a thin polypropylene film may be bonded. By using cardboard, the feel is improved and various patterns can be printed easily. Further, since a polypropylene film thinner than that of the sheet 2 is used, it is not necessary to preheat the mold at the time of welding.
