However, in such a conventional card case, separately from the facing sheet, it is necessary to prepare the intermediate plate and the strip-like ribs sandwiched between the sheets in advance and weld or paste them, There is a problem in that the production and bonding of the intermediate plate and the strip-like ribs take time and increase the cost.
Furthermore, in order to prepare a plurality of card cases of different sizes, it is necessary to produce the intermediate plate and the strip-like ribs corresponding to the sizes, and it takes time to manage the parts, resulting in high costs. There was also a problem.
In addition, in such a conventional card case manufacturing method, the intermediate plate and the strip-like ribs are aligned and welded or pasted along the three peripheral edges of the opposing sheets, which requires time and effort in the manufacturing process. As the cost increases, the dimensional accuracy of the intermediate plate or the strip-like ribs decreases, or the arrangement of the intermediate plate or the strip-like ribs relative to the peripheral edge of the sheet becomes complicated, the appearance deteriorates. There was a problem that the merchandise value declined.

  An object of the present invention is to deal with such a problem, in which the peripheral portions of the sheets are directly bonded to each other with a strip-shaped spacer made of an adhesive, and the peripheral portions of the sheets are overlapped with each other. The purpose is to bond them together with a belt-like spacer.

  In order to achieve such an object, the card case according to the present invention includes a sheet provided so as to face each other, and a belt-like shape provided along the peripheral edge of the sheet to form a card storage space between the sheets. The belt-shaped spacer is made of an adhesive that cures from the heat-melted state into a belt shape and adheres to the peripheral edge of the sheet, and the thickness of the belt-shaped spacer is inserted into the card storage space. The card is characterized in that it is formed to be the same as or thicker than the thickness of the card.

  The card case manufacturing method according to the present invention may be configured to supply the adhesive in a strip shape along one of the peripheral edges of the sheet to form the strip spacer, and then sandwich the strip spacer. The other edge of the sheet is overlapped, the edge of the sheet and the strip spacer are pressed and bonded to each other with a predetermined pressure, and the thickness dimension of the strip spacer is inserted into the card storage space. The thickness of the card is equal to or greater than that of the card.

In the card case according to the present invention having the above-described features, the belt-shaped spacer provided between the peripheral portions of the opposing sheets is composed of an adhesive that cures from the heat-melted state into a strip shape and adheres to the peripheral portions of the sheet. Thus, a card storage space that is the same as or thicker than the thickness dimension of the card is formed between the opposing sheets at the same time with the adhesive serving as a strip spacer interposed therebetween. Therefore, the peripheral portions of the sheets can be directly bonded to each other at a predetermined interval with a belt-like spacer made of an adhesive.
As a result, it is necessary to prepare a belt-like spacer in advance and weld or stick it to the peripheral edge of the sheet, compared to the conventional one in which an intermediate plate or a strip-like rib is prepared separately from the facing sheet and welded or pasted. Therefore, the structure can be simplified and the cost can be reduced.
Further, when a plurality of card cases having different sizes are prepared, it is not necessary to prepare a belt-like spacer corresponding to the size in advance, so that parts management is simplified correspondingly, and cost can be reduced.

Further, in the card case manufacturing method according to the present invention having the above-described features, the strip spacer is formed so as to surround the card storage space by supplying the adhesive in a strip shape along one of the peripheral portions of the sheet. Then, the peripheral edge of the other sheet is overlapped so as to sandwich the belt-like spacer, and by pressing them with a predetermined pressure, the thickness dimension of the belt-like spacer becomes the thickness dimension of the card inserted into the card storage space. Since they are the same or thicker, the peripheral portions of the sheets can be bonded to each other with a belt-like spacer during the overlapping process.
As a result, it is not necessary to prepare a belt-shaped spacer in advance, compared to a conventional manufacturing method in which a previously prepared intermediate plate or strip-shaped rib is aligned and welded or pasted along the three peripheral edges of the facing sheet. Since it is not necessary to arrange the strip spacers side by side, it is possible to manufacture a card case with excellent appearance at a low cost.

Specific examples of the soft synthetic resin constituting the sheets 1 and 2 include polyester resins and olefin resins. Furthermore, as the polyester resin, for example, polyethylene terephthalate (PET) is preferably used, and as the olefin resin, for example, polypropylene (PP) is preferably used.
In addition, as the sheets 1 and 2, a single-layer sheet made of only a single soft synthetic resin, or a multi-layer sheet in which a plurality of soft synthetic resins are integrally laminated is used. Specific examples thereof include an A-PET single layer sheet, a PP single layer sheet, and a PET-G / A-PET / PET-G three-layer sheet.

The belt-like spacer 3 is composed of a translucent adhesive 3a added with a transparent or coloring agent that is cured from a heat-melted state into a belt-like shape and adheres to the peripheral portions 1a and 2a of the sheets 1 and 2, respectively. The two surfaces 3b and 3c are bonded to the peripheral edges 1a and 2a of the sheets 1 and 2, respectively, by being arranged so as to be sandwiched between the two.

More specifically, the adhesive 3a constituting the belt-like spacer 3 is supplied in a belt-like shape along the peripheral edge portions 1a and 2a of the sheets 1 and 2 in a heated and melted state, for example, by coating or printing. The both surfaces 3b and 3c are bonded to the peripheral portions 1a and 2a of the sheets 1 and 2 respectively, and the thickness dimension of the card B is equal to or more than that between the opposing sheets 1 and 2 A slightly thicker card storage space S is formed.
Specific examples of the adhesive 3a include a hot melt mainly composed of a rubber or a thermoplastic resin. Furthermore, it is preferable to use a high-viscosity jelly type as the adhesive 3a.

According to such a card case A according to the embodiment of the present invention, the adhesive 3a serving as the strip spacer 3 is sandwiched between the peripheral edges 1a and 2a of the opposing sheets 1 and 2, and the front and back surfaces 3b and 3c are A card storage space S that is the same as or slightly thicker than the thickness of the card B is formed between the opposing sheets 1 at the same time as being bonded to the peripheral edges 1a and 2a of the sheets 1 and 2, respectively.
Thereby, the peripheral parts 1a and 2a of the sheet | seats 1 and 2 can be directly bonded together by the strip | belt-shaped spacer 3 which consists of an adhesive agent 3a at predetermined intervals.

In particular, when a high-viscosity jelly-type adhesive is used as the adhesive 3a constituting the belt-like spacer 3, even if the adhesive 3a is supplied in a belt-like shape in a heated and melted state, it does not drip and is naturally cooled. It is cured as supplied.
Thereby, the card storage space S can be formed reliably.
As a result, the dimensional accuracy can be improved and the quality can be made uniform.

  And the manufacturing method for producing the card case A which concerns on embodiment of this invention, as shown to Fig.2 (a)-(d), either one of the sheets 1 and 2, ie, one sheet 1, is carried out. An arrangement process of placing the sheet at a predetermined position, a forming process of supplying the adhesive 3a in a strip shape along the peripheral edge portion 1a of one sheet 1 to form the strip spacer 3, and a strip shape on the peripheral edge portion 1a of the one sheet 1 A superposition step of superposing the peripheral edge portion 2a of the other sheet 2 with the spacer 3 interposed therebetween, and a pressurizing step of pressurizing the peripheral edge portions 1a, 2a of both the superposed sheets 1 and 2 and the belt-like spacer 3 with a predetermined pressure; Is included.

As shown in FIG. 2A, the placing step places one sheet 1 on a flat processing surface C such as a surface plate and makes it impossible to move by, for example, vacuum suction means (not shown). Positioning.
At this time, it is also possible to automatically carry the sheet 1 from the supply source toward a predetermined position using a transfer means (not shown) such as a transfer robot.

As shown in FIG. 2B, the step of forming the belt-like spacer 3 is performed by applying the adhesive 3a along the peripheral edge portion 1a of the sheet 1 positioned by the placement step, or supplying the belt-like spacer 3 by printing or the like. The band-shaped spacer 3 is formed so as to surround the card storage space S by curing it in its applied shape or printed shape by natural cooling or the like.
Thereby, the sheet 1 side surface 3b of the belt-like spacer 3 is adhered to the peripheral edge 1a of one sheet 1 in a transparent or translucent manner.

In the overlapping process, as shown in FIG. 2C, the peripheral edge 2a of the other sheet 2 is opposed to the peripheral edge 1a of one sheet 1 with the belt-like spacer 3 formed in the forming process interposed therebetween. Are superimposed.
As a result, the sheet 2 side surface 3c of the belt-like spacer 3 is adhered to the peripheral edge 2a of the other sheet 2 in a transparent or translucent manner.
At this time, it is also possible to automatically carry in from the supply source of the sheet 2 toward the belt-like spacer 3 using a transfer means (not shown) such as a transfer robot.

In the pressurizing step, as shown in FIG. 2 (d), the peripheral portions 1 a and 2 a of the both sheets 1 and 2 and the belt-like spacer 3 that are overlapped by the overlapping step are pressed toward the processing surface C with a predetermined pressure. While cooling, the thickness of the belt-like spacer 3 is hardened so as to be the same as or slightly larger than the thickness of the card B inserted into the card storage space S.
Thereby, as shown in FIG. 1A, a card case A in which the interval between the card storage spaces S is equal to or slightly thicker than the thickness dimension of the card B is produced.

According to the manufacturing method of the card case A according to the embodiment of the present invention, the adhesive 3a is supplied in a band shape by coating or printing along one of the peripheral portions 1a and 2a of the sheets 1 and 2. Thus, the belt-like spacer 3 is formed so as to surround the card storage space S, and then the peripheral edge portion 1a of the other sheet 1 is overlapped so as to sandwich the belt-like spacer 3, and the peripheral edge portions 1a, 2a of these two sheets 1, 2 are overlapped. And by pressing the strip spacer 3 with a predetermined pressure, the thickness dimension of the strip spacer 3 is the same as or thicker than the thickness dimension of the card B inserted into the card storage space S.
Thereby, the peripheral parts 1a and 2a of the sheets 1 and 2 can be bonded to each other by the belt-like spacer 3 during the overlapping process.
Next, an embodiment of the present invention will be described with reference to the drawings.

  The card case A according to this embodiment is a name tag holder for inserting and holding an exhibition card such as an ID card or a name tag as a card B in the card storage space S, as shown in FIGS. 1 (a) and 1 (b). In addition, the sheets 1 and 2 are formed in a rectangular shape having substantially the same size, and a belt-like spacer 3 is provided in a U-shape on the three peripheral edges 1a and 2a except for one side of each inner surface. For example, a hanging tool (not shown) made of an annular thread, string, or the like is attached, and the like is used to hang from the neck.

As the sheets 1 and 2, a single-layer sheet of A-PET, a single-layer sheet of PP, or a triple-layer sheet of PET-G / A-PET / PET-G is used.
As the adhesive 3a constituting the belt-like spacer 3, rubber-based hot melt or the like is used.

Further, in the example shown in FIGS. 1A and 1B, one side arranged on the opening side of the sheets 1 and 2 is linearly formed.
Although not shown in the drawings as other examples, a through hole or a projection for attaching an end of a suspension or a clip connected to the end is formed on one side arranged on the opening side of the sheets 1 and 2. It is also possible.

  According to the card case A according to the embodiment of the present invention, an inexpensive single layer or multilayer sheet such as PET or PP can be used as the sheets 1 and 2, and a rubber-based hot melt or the like is used as the adhesive 3a. Therefore, there is an advantage that the cost can be reduced and it is difficult to break.

  And the manufacturing method of the card case A which concerns on this Example apply | coats the adhesive agent 3a as shown in FIG.2 (b) in the formation process of the strip | belt-shaped spacer 3, and FIG.2 (d) in a pressurization process. The pressing means F presses the peripheral portions 1a and 2a of both sheets 1 and 2 and the belt-like spacer 3 as shown in FIG.

In the example shown in FIG. 2B, for example, a liquid fixed amount discharger D such as a dispenser is used, and this liquid fixed amount discharger D is connected to the peripheral portion 1a of the sheet 1 with an NC (numerical control) device (not shown). The adhesive 3a is applied with a uniform thickness by being moved along the opposing U-shaped track E. The adhesive 3a used at that time is preferably a rubber-based adhesive that is heated and melted to about 100 to 145 ° C., for example.
Although not shown in the drawings as another example, the liquid dispensing dispenser D is moved manually along the U-shaped path E without using an NC device, or a known printing machine such as screen printing is used. Thus, the adhesive 3a can be printed with a uniform thickness.

In the example shown in FIG. 2D, the belt-like spacer 3 is cured by natural cooling or the like while the other sheet 2 is directly pressed toward the one sheet 1 by the pressing means F such as a hydraulic cylinder. . As the pressing means F, it is preferable to use one that can adjust the amount of expansion and contraction and further has a cooling function.
Although not shown as another example, a flat cooling block (not shown) larger than the sheets 1 and 2 is sandwiched between the pressing means F and the other sheet 2 so that the whole of the other sheet 2 is even. The belt-like spacer 3 is forcibly cooled at the same time, or a weight (not shown) made of metal or the like is placed on the other sheet 2 instead of the pressing means F or the cooling block. It is also possible to forcibly cool the belt-like spacer 3 at the same time that the entire sheet 2 is pressed evenly.

According to the manufacturing method of the card case A according to the embodiment of the present invention, there is an advantage that the manufacturing process is simplified and the card case A can be manufactured at low cost.
In particular, when the pressing means F having a cooling function is used, there is an advantage that the processing speed can be increased, thereby further reducing the cost of the card case A.

2A to 2D show the case where one card case A is manufactured, a plurality of card cases A can be manufactured simultaneously.
In this case, since the card case A can be mass-produced, there is an advantage that the cost can be further reduced.

In the embodiment described above, the card case A is a name tag holder for inserting and holding an exhibition card such as an ID card or a name tag as the card B, and a hanging device made of thread or string is attached to the opening side of the card case A. However, the present invention is not limited to this, but it is not limited to this, and it can be used only in the card case A unit without attaching the hanging tool, or an exhibition card such as an ID card or a name tag. In addition to the name card holder that holds the card, a card such as a ticket or cardboard may be used. Further, for example, it is possible to use a two-fold card case such as a book cover as described in JP-A-2003-116616.
In these cases, the shape and size of the sheets 1 and 2 change according to the intended use, and the shape and size of the belt-like spacer 3 change accordingly.
