Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an encapsulating case for a thin plate product, and more particularly to an encapsulating case that allows a thin plate product to be beautifully stored and held with a simple structure and handling operation.

[0002]

2. Description of the Related Art Thin plate-shaped products such as memory cards are put in an enclosing case and put on the market in order to be handled as good-looking products or products that are easy to handle and store. In other words, at least a part of the encapsulation case is made transparent, and the product is protected by storing and mounting it so that the memory cards can be seen through, while at the same time, it is hung by a hook or the like.
Measures are taken to improve the appearance (exhibitability) of products.

And, as such a packaging case,
The following configurations are known. That is, a transparent case body that has a product storage portion with a convex cross-section and is bent into a groove shape that can hold other edges except one edge, and that is fixed from one edge side of this transparent case body. A configuration is known in which a plate is inserted, and an edge of a fixing plate is sandwiched between the bent groove portions to seal the opening of the convex product storage portion (Japanese Patent Laid-Open No. 10-203711). There is. In addition,
In the structure of the encapsulating case, the shape and depth of the convex product storage portion are generally set in accordance with the shape and thickness of the thin plate-like product to be stored and arranged.

FIG. 5 is a plan view showing in perspective a structural example of a conventional encapsulating case for thin plate-shaped products. In FIG. 5, 1
Is a transparent case body that has a convex product storage portion 2 and is bent into a groove 3 into which other edges 1b, 1c, 1d except one edge 1a can be inserted. Here, the convex product storage portion 2 of the transparent case body 1 corresponds to a thin plate-like product to be sealed, and is set in length, width, and height (depth). The edges 1b, 1c, 1d of
A groove 3 having a bending width of about 10 mm is formed and then bent.

Further, 4 is inserted from one end edge 1a side of the transparent case body 1, and the end edge portion is slidably sandwiched by the groove 3 formed by bending, and the convex product storage portion 2 is provided. It is a fixed plate that integrates while sealing the opening. Here, the fixing plate 4 is, for example, a coated cardboard, and is a groove formed by bending the edges 1b, 1c, 1d of the transparent case body 1 when it is inserted from the edge 1a side of the transparent case body 1. Three
In addition, the edges are fitted and pinched to be integrated.

[0006]

However, the conventional case has the following disadvantages. That is, the shape and size of the product storage portion 2 having a convex cross-section, particularly the depth of the product storage portion 2 having a convex shape is selected and set in consideration of the thickness of the thin plate-shaped product. When the transparent case body 1 and the fixing plate 4 are deformed due to a mechanical impact, the thin plate-shaped product 5 is displaced along the fixing plate 4 from the convex product storage portion 2, and the good-looking sealing / holding may be impaired. is there.

More specifically, the transparent case body 1,
The integration with the fixing plate 4 is merely carried out by slidingly sandwiching the end edge portion of the fixing plate 4 into the bent groove 3 of the transparent case body 1. That is, the transparent case body 1 forming the encapsulating case and the fixing plate 4 are fixedly integrated at the outer peripheral edge portion, and the fixing plate 4 is the convex product storage unit 2
Although the opening 2a is sealed, the opening 2a of the convex product storage 2 has a gap between the transparent case body 1 and the fixing plate 4 when an external impact is applied. Easily occurs. Then, when such a gap is generated, the thin plate-shaped product 5 having a thickness of about 0.3 to 5 mm, particularly about 0.3 to 2 mm is removed from the convex product storage unit 2 and runs along the fixed plate surface. There is a problem in that the appearance of the product is impaired due to the slippage.

In particular, in this type of encapsulation case, since the thin plate-like product 5 is vertically arranged and accommodated in the case, a drop due to gravity is likely to occur, which impairs the appearance of the packaged product. In order to avoid such a deterioration in appearance or appearance, the thin plate-shaped product 5 is temporarily held by a third member such as a cushion material, and the product storage unit 2 holds this.
It is configured to be stored and arranged in. However, if such a means is adopted, not only the structure becomes complicated and the storing operation becomes complicated, but also the resources of the packaging case are wasted.
In other words, the use of the third member increases the number of parts in the encapsulation case and the combination of parts, which not only complicates the storage operation of the product but also increases the recycling resource and the waste resource, and raises the cost problem. To do.

Further, when accommodating and arranging the thin plate-like product 5 in the product accommodating portion 2, it is conceivable to fix the product in the product accommodating portion 2 by using an adhesive tape or the like. When fixing this thin plate product 5 with adhesive tape,
It is superior in resource saving as compared with the case of using the third member. However, in practice, the operation of storing and arranging the thin plate-shaped product 5 in the product storage unit 2 and the operation of removing the thin plate-shaped product 5 from the product storage unit 2 are complicated, so that the packaging work efficiency is poor and the productivity is significantly reduced. There are inconveniences such as being lost.

The present invention has been made in consideration of the above circumstances, and while adopting a simple structure, avoiding a slip of a thin plate-like product without requiring a complicated packaging operation, , It is intended to provide an encapsulating case for thin plate-shaped products which can maintain a desired appearance.

[0011]

According to a first aspect of the present invention, there is provided a product storage portion having a convex cross-section, and the other end edge portion excluding one end edge is bent into a groove shape and is transparent. Fixing in which the case main body and the transparent groove main body are slidably sandwiched between the one end edge and the grooved portion of the transparent case main body, and the opening of the convex product storage is sealed and integrated. A plate and a tapered projection disposed on the inner peripheral surface of the opening of the convex product storage portion and abutting the outer peripheral edge of the thin plate-shaped product to be stored and arranged to lock the thin plate product in the convex product storage portion. Is a thin plate-shaped product encapsulating case.

According to a second aspect of the present invention, in the encapsulating case for a thin plate-shaped product according to the first aspect, the tapered projections are arranged at a plurality of positions separated from each other.

In the first and second aspects of the invention, the transparent case body is a three-dimensionally molded body made of, for example, polyethylene resin or polyethylene terephthalate resin. Then, in order to store and arrange a predetermined thin plate-shaped product, 0.3 to 2 m to the outside at one end side or the central part
A convex product storage portion protruding about m is provided. Examples of the thin plate-like products to be sealed include cards such as memory cards and sheet-like batteries.

Further, the edge of the transparent case body is a surface opposite to the surface of the product storage portion having a convex cross section so that other edges except the one edge can form a groove shape. It is bent to the side. Here, the groove-like formation that can be sandwiched may be intermittent. That is, the groove shape that can be sandwiched is such that when the fixing plate is inserted from the one end edge side that is not bent, the end edge portion of the fixing plate slidably fits into the groove of the bending process and is integrated and Since it contributes to the maintenance, it may be set to the extent that such a function can be secured.

According to the first and second aspects of the present invention, the edge portion is slidably sandwiched by the groove portion of the transparent case body, and the opening of the convex product storage portion is sealed and integrated. The plate is a molded body made of, for example, coated balls (paper quality), hard polyethylene resin, or polyethylene terephthalate resin. Here, the fixing plate may be of a folded type, and the inner surface of the folding may be used as a location for describing the instruction manual of the thin plate product or a location for storing the instruction manual. Also, when the fixing plate is made of a transparent material, accessories such as an instruction manual and a carrier case can be inserted and stored between the fixing plate and the transparent case body. Furthermore, it is advantageous for recycling if the fixing plate is made of the same material as the transparent case body.

According to the first and second aspects of the invention, the tapered projections that are in contact with the outer peripheral edges of the thin plate-shaped products that are stored and arranged to lock the thin plate-shaped products in the product storage part having a convex cross-section are generally used. In addition, they are distributed and arranged on opposite sides or positions. That is, a plurality of tapered projections are provided separately from each other on the inner peripheral surface of the opening end of the convex product storage portion of the transparent case body. Here, the tapered projection can be easily inserted / removed in / from the convex product storage unit by inclining the thin plate-shaped product, while it is tapered so that the thin plate product can be locked in the convex product storage unit. It is attached.

The tapered projection has a structure in which the opening end side of the convex product storage portion is tapered and the convex side is flattened, and the opening end side of the convex product storage portion is flattened.
Either the configuration in which the convex side is tapered or the configuration in which both the opening end side of the convex product storage portion and the convex side are tapered may be used. In other words, the tapered protrusion allows the thin plate-like product to be introduced and installed along the tapered surface, and
After insertion and mounting, the stopper is symmetrically tapered corresponding to the shape of the thin plate-shaped product so that the thin plate-shaped product does not come off from the product storage portion as the locking portion.

According to the first and second aspects of the invention, the tapered projections on the inner peripheral surface of the product storage portion lock the outer peripheral edge of the thin plate-shaped product stored and arranged. That is, the thin plate-shaped product can be easily inserted into and removed from the product storage portion along the tapered surface. Then, in the state where the thin plate-shaped product is inserted and mounted in the product storage unit, the thin plate-shaped product is locked in the product storage unit by the tapered protrusion.

Therefore, in the packaged thin plate product, even if a gap is created between the product storage portion and the fixed plate due to an external impact or the like, there is no fear that the thin product will be displaced along the fixed plate from the inside of the product storage portion. . In other words, even if the product package receives an external shock and a gap is created between the case body and the fixing plate, the thin plate-shaped product that is stored and stored is locked in the product storage section, Eliminates the risk of being detached or dropped from inside the unit.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, FIG. 1, FIG. 2, FIG.
An embodiment will be described with reference to (b), (c) and FIGS. 4 (a), (b).

FIG. 1 and FIG. 2 show the structure of a main part of a packaging case for a memory card (thin plate product) according to an embodiment. FIG. 1 is a perspective top view and FIG. It is an expanded transverse sectional view along the AA line.

In FIGS. 1 and 2, reference numeral 1 denotes a product storage portion 2 having a convex cross-section, and other end edges 1b, 1 excluding one end edge 1a.
The transparent case main body is formed by bending a groove 3 into which c and 1d can be sandwiched. Here, the transparent case body 1 is
It is a vacuum-molded product made of polyethylene terephthalate resin with a thickness of about 0.3 mm. The sides of the edges 1a and 1b are about 90 mm, and the sides of the edges 1c and 1d are about 150 mm. It has a convex product storage 2 having a width of 50 × 40 mm and a depth of 6 mm. The edges 1b, 1c, 1d of the transparent case body 1 have a groove shape 3 having a bending width of about 10 mm and a width of about 1 mm.
It is bent into.

Reference numeral 4 denotes a product storage portion having a convex cross-section, which is inserted from the end edge 1a of the transparent case body 1 and has the end edge portion slidably sandwiched in a groove 3 formed by bending. This is a fixing plate that integrates the two openings 2a while sealing them. Here, the fixing plate 4 is a coated cardboard plate (folded in two) having a length and width of 150 × 90 mm and a thickness of 0.5 mm.
From the side of the edge 1a of the transparent case body 1 to the edge 1
Edges are formed so as to be integrated by being fitted and sandwiched in the groove 3 formed by bending the b, 1c and 1d portions.

Further, 6 is disposed on the inner peripheral surface of the opening 2a of the convex product accommodating portion 2 and comes into contact with the outer peripheral edge of the thin plate-shaped product 5 accommodated and accommodated in the convex product accommodating portion 2. It is a projection with a taper that locks the thin plate-shaped product 5. Here, the tapered projections 6 are formed by partially projecting a plurality of locations on the inner peripheral surface of the convex product storage portion 2 on the side of the opening 2a in the vacuum molding process of the transparent case body 1. That is,
A length of about 10 mm, a thickness of about 2 mm, and a protruding height of 2 mm, which are opposed to the inner peripheral surface on the opening 2a side of the convex-shaped product storage portion 2 in section.
The tapered protrusion 6 that spreads to the side of the opening 2a is formed in a vacuum forming process. In FIGS. 1 and 5, 7 is a hanging hole.

Next, an example in which the memory card 5 is housed and arranged in the packaging case for the thin plate-like product having the above-mentioned configuration to form a package will be described. First, the memory card 5 is housed and arranged in the product housing portion 2 having a convex cross-section in the transparent case body 1.
Here, the convex product storage unit 2 is slightly larger than the shape and size of the memory card 5 to be stored and arranged.
It is set to dimensions. The protrusion 6 provided on the inner peripheral surface of the convex product storage portion 2 on the side of the opening 2a has the opening 2a.
Since it has a taper that spreads to the side, by inserting the memory card 5 along this tapered surface, it can be easily stored and arranged in the convex product storage portion 2.

After the memory card 5 is housed and arranged in the product housing 2 having a convex cross section, the outer peripheral edge of the memory card 5 is locked to the flat surface of the tapered projection 6. In other words, even if the memory card 5 stored and arranged in the convex product storage portion 2 has a storage arrangement that is slightly loose in appearance, the taper protrusion 6 locks the memory card 5.
There is no fear of moving from the convex product storage 2 to the fixed plate 4 side. Therefore, even if the fixing plate 4 is deformed with respect to the case main body 1 and a slight gap is generated due to an external impact or the like, the fixing plate 4 will not be displaced along the fixing plate 4.

After the memory card 5 is housed and arranged in the product housing portion 2 having a convex cross section of the transparent case body 1,
The edge of the fixing plate 4 is aligned with the groove 3 of the edge 1c, 1d of the transparent case body 1. After that, the fixing plate 4 is inserted and mounted from the one end edge 1a side of the transparent case body 1, and the opening 2a of the convex product storage portion 2 is closed (sealed) while being inserted and pinched in the groove portion 3. Transparent case body 1
On the other hand, the fixing plate 4 is integrated and packaging is performed by this integration. The fixing plate 4 may be integrated with the transparent case body 1 depending on the presence / absence and degree of loose fitting during insertion / mounting of the fixing plate 4 with respect to the groove 3 of the edge portions 1b, 1c, 1d of the transparent case body 1. Stapling or the like may be used in combination with the conversion.

The packaged product of the memory card 5 by the transparent case body 1 and the fixing plate 4 is stored in the product storage unit 2 even if it is subjected to shocks or vibrations in, for example, box packing work, transportation work, or transportation work. The occurrence of misalignment is no longer recognized. That is, the packaged product of the memory card 5 does not have a risk of being detached from the product storage portion 2 having a convex cross-section regardless of a general impact or a position and a direction in which the product is placed, so that the appearance of the product is easy. It was confirmed that

In the above embodiment, the tapered projection 6 has a rectangular shape in a plan view and a triangular cross section that spreads toward the opening 2a side.
The shapes shown in FIGS. 3A, 3B, and 3C may be used. The cross-sectional shape is also shown in FIGS.
Even if the shapes and structures shown in FIG.

The cross-sectional shape of the tapered projection 6 is such that, when the outer peripheral end face of the thin plate-shaped product 5 is vertical, the taper spreads toward the opening 2a side and the mounting side of the thin plate-shaped product 5 is set flat. When the outer peripheral end surface of the thin plate-shaped product 5 has a curved shape, it is preferable that the taper is spread to the mounting side of the thin plate-shaped product 5 and the opening 2a side is set flat. That is, in these cases, the thin plate-shaped product 5 can be locked more stably by the tapered protrusion 6.

The present invention is not limited to the above embodiments, but various modifications can be made without departing from the spirit of the invention. For example, thin plate products to be packaged are not only memory cards but also 0.3 to 5 m thick.
It is possible to target other types of cards such as m and sheet batteries. Of course, the material of the transparent case body, the shape and structure of the product storage portion, and the like are appropriately selected and set according to the type, shape, and size of the thin plate product to be packaged.

[0032]

According to the first and second aspects of the present invention, the thin plate-shaped product can be easily accommodated in the product accommodating portion along the taper of the tapered projection, while being locked in the product accommodating portion. Thus, a sealing case that can prevent the fixed plate from being detached is provided. That is, it is possible to provide a good-looking product package that does not cause the stored product to be displaced from the product storage unit even if it receives a slight shock or vibration during the transportation process.
