Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention is a case suitable for storing and displaying ornaments such as necklaces, pendants, and bracelets.

<Prior art> In the past, plastic was the main material and mass production was performed using a mold.

The case itself is a mass-produced item, and even though it is inexpensive, it requires a large amount of money for molding, and is made from imported precious petroleum-based synthetic resin resources.
High-mix, low-volume production was rather expensive.

<Purpose of the invention> The invention uses cardboard or other paper that can be obtained at the lowest cost as a core material, does not use any molding die,
It is an extremely simple and practical case that can be completed by simply punching out the original shape, gluing the exterior material, folding it up, and inserting the product mount inside.

<Example> Embodiments of the present invention will be described with reference to the drawings.

Case A shown in FIGS. 2 and 3 is a case with a hexagonal cross section, and FIG. 1 is a developed view of its core paper.

The core paper 1 is made by punching out cardboard, and extends horizontally through the vertical folding lines ₄ , 4 _, . The triangular side plates 5' ₁ to 5' ₆ are connected to each other, and an overlapping piece 6 is connected to one end of the side plate 5 ₆ via a vertical folding line 3.

Each triangular side plate 5' _{1 -} of the core paper punched in the above configuration and with each folding line 2, 3, 4 engraved on the surface side.
5' and ₆ are equilateral triangles because they are adjacent to each other in the folded state to form a hexagon, but if necessary, they can be made into triangles of a size and angle that can form other polygonal cross sections, or , its side plate is also correspondingly 5
It goes without saying that it can be made from ₁ to 5n.

The most distinctive feature of the present invention is that a decorative material 7 such as leather, velvet, satin, processed paper, etc., is applied to the surface of the core paper 1 using an appropriate adhesive, as shown in FIG. A notch is formed between each of the triangular side plates 5' ₁ to 5' ₆ of the core paper 1, but the decorative area 7 is applied by covering the entire core paper from the front and back, including the notch part. , the space between each triangular side plate constitutes a flexible connecting portion 6'' without a core paper.

In addition, in the case of core paper having a triangular prism cross section, the side plates 5 ₁ to
Triangular side plates 5' ₁ are provided above and below the central side plate 5 ₂ of 5 ₃ , and a decorative plate is pasted to cover the upper and lower outer circumferences of the triangular plate and both side plates 5 ₁ and 5 ₂ to form a flexible connecting plate 6''. .

During this adhesion, the amount of space on the outer fabric at each fold line is adjusted as appropriate depending on the thickness and elasticity of the outer fabric.

When attaching the outer material, a ready-made plate hinge with a simple structure that can be freely bent may be attached to the core paper by driving it across the folding line at the appropriate position on the inside.

The entire surface of the core paper may be covered with the decorative material 7, but if the inside is made separate, the front side is pasted, and then an interior material of the desired color and material is pasted and covered.
A lining material with product hanging tools C attached at predetermined locations is attached to the inner surface of the core paper 1.

In the figure, D and D' are hanging brackets attached to each lid plate,
E indicates products such as Netskuress.

The proposed case with the above structure does not require expensive molding molds that can be amortized only through mass production, unlike conventional plastic molded products, and can be used to manufacture high-mix, low-volume products with rapidly changing trends. Then, using a low-cost cardboard or the like as a core paper, this is punched out into a flat shape with the plurality of side plates and triangular side plates arranged in series using a conventionally known Thomson punching machine to form a hexagonal columnar cross section or other polygonal cross section. A prototype core paper for the case can be created, and all you have to do is apply glue or other adhesive to the flattened core paper, attach the decorative area 7 of various materials, or the surface decorative area and lining, and fold up the side panels. Since it can be made with simple steps, it does not require any skill or tools.

In this embodiment, a hexagonal cross section is shown, but it goes without saying that the cross section may be polygonal other than hexagonal depending on the shape of the triangular side plate.

<Function> Therefore, even if expensive cloth or leather is used for the outer material, lining, etc., the cost is much lower than that of the molding mold described above, and the product is lightweight and easy to store and carry.

Moreover, in the case of the present invention having the above-mentioned configuration, the folded portions of each corner of the side plate are used as interlining-free portions, and the outer material and other parts serve as hinges when the case is unfolded, and when folded, each connecting portion 6'' naturally faces inward. The case is constructed by folding the case into a lid and a main body, with each side panel closely butted against the adjacent sides.

<Effects> As described above, the material composition of the present invention is extremely simple, and the production does not require any mechanical elements, equipment, or skill, and it is possible to produce cases with luxurious exteriors in small quantities and in a wide variety of products at low cost. This is an excellent idea.
