Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a small case for storing watches, precious metals, etc., and particularly relates to a small case in which a covering material is attached to the surface of a synthetic resin base.

(b) Prior Art The commercial value of watches, precious metal accessories, etc. is significantly reduced due to surface damage caused by contact with other items. Therefore, to avoid contact with other items, watches and ornaments are sold individually in sturdy cases. Furthermore, since luxury is important in the case of decorative items such as watches, small cases for storing such items are required to be both sturdy and decorative with a luxurious feel.
For this reason, the above-mentioned accessory case is generally constructed as an upper and lower halves that can be opened and closed using the back as a hinge. It is covered with a covering material. Furthermore, some have rounded edges where the two sides of the casing join to create a softer image. In such a small case with rounded edges, the corner where the three sides join exhibits a three-dimensional curved surface.

(c) Problems to be solved by the invention However, the covering material attached to the surface of the base in small item cases is formed in the form of a sheet made of cloth, synthetic or natural leather, etc. If it is casually attached to the surface of a substrate whose corners exhibit a three-dimensional curved surface, wrinkles will occur in the coating material at these corners due to loosening, giving a troublesome image to the viewer and spoiling the luxury of the product. . Therefore, in order to apply the coating material to prevent wrinkles from forming, pinch the edge of the coating material near the part to be applied to the corner of the base with your fingertips, and use an instrument such as an awl to pull the edge of the coating material around the corner of the substrate. Covering material must be applied to the area and excess covering material must be removed by cutting. Furthermore, in order to prevent wrinkles from occurring in the coating material due to shrinkage until the adhesive is completely cured, a special presser mold is used after the coating material is attached to the substrate. The dressing must be kept in place by using As described above, in conventional accessory cases, the work of pasting the covering material on the corners exhibiting a three-dimensional curved surface is complicated, requires advanced technology and skill, and requires a long time.

The purpose of this invention is to form a hole near the corner of a three-dimensional curved surface, insert the excess covering material near the corner into this hole, and then cover this hole with a lid. This makes it possible to easily apply the coating material without peeling or damaging the surface of the coating material, and without creating wrinkles at the corners, reducing costs by improving work efficiency, and reducing the cost of materials. The object of the present invention is to provide a case for small items that can achieve uniform product quality through standardization.

(d) Means for solving the problem The accessory case of this invention is a case in which a covering material is pasted on the surface of a base body where the corner where the three faces join exhibits a three-dimensional curved surface. A hole is formed near the corner of the ridgeline where the two sides join, into which the end of the covering material affixed to the corner is inserted, and the covering material inserted into the hole is aligned with the inner peripheral surface of the hole. It is characterized in that a lid is provided which fits into the hole and is sandwiched between the lids.

(e) Function In this device, when a covering material is attached to a corner, excess covering material that causes wrinkles in the covering material can be inserted into the hole, and the cover can be inserted into the hole. By fitting them together, the surface of the base can be maintained smooth. At this time, since the covering material is sandwiched between the lid body and the inner circumferential portion of the hole, the state in which the covering material is firmly attached to the corner portion is maintained. Therefore, there is no need to cut off the excess part of the covering material near the part to be pasted to the corner, and after the covering material is pasted, it is fixed using a presser mold etc. until the adhesive is completely cured. There's no need.

(f) Embodiment FIG. 2 is an external view of an accessory case that is an embodiment of this invention.

The accessory case 21 is configured into a casing divided into upper and lower halves by an upper member 22 and a lower member 23, and the back is hinged by hinges (not shown) attached to the backs of the upper and lower members 22 and 23. It can be opened and closed freely. In addition, the accessory case 21 is rounded at the joints on two sides (for example, the ridgeline part 28 that is the joint between the top surface and the front surface of the upper member 22), and at the joints on three sides (for example, at the joints on the three sides of the upper member 22).
A corner portion 27), which is a joint between the top surface, front surface, and right side surface in 2, has a three-dimensional curved surface.

The upper member 22 and the lower member 23 are formed by applying a covering material made of cloth, synthetic or natural leather to the surfaces of an upper base body and a lower base body formed by resin molding. The covering material affixed to the surface of the base body includes an upper covering material 26 having stitches at both ends, lower covering materials 24a, 24b, and 25a and 25b.

The lower covering materials 24a and 24b are attached so as to cover both left and right side surfaces of the upper member 22 and their vicinity together with the ridgeline and corners, and the lower covering materials 25
a and 25b are attached so as to cover both left and right side surfaces of the lower member 23 and their vicinity together with the ridgeline and corner. The upper covering material 26 covers the front, upper and back surfaces of the upper member 22, the back surface of the lower member 23,
It is pasted on the bottom and front. Therefore,
The upper covering material 26 is continuous on the back surfaces of the upper member 22 and the lower member 23, and covers the hinges attached to the back surfaces of the upper member 22 and the lower member 23 so that they are not exposed to the outside.

FIG. 1 is a perspective view showing the vicinity of a corner of the base of the accessory case.

This figure shows the vicinity of a corner 2 where three surfaces of the upper base 1, the top surface, the front surface, and the right side surface, are joined. This corner 2 is connected to the lower covering material 24 shown in FIG.
covered by a. Step portions 6 and 7 are continuously formed on the upper surface, front surface, and back surface of the upper base body 1 near the left and right side surfaces thereof. A hole 3 is formed in the stepped portions 6 and 7 at a portion perpendicular to a ridgeline portion where the upper surface and the front surface join near the corner portion 2. Protrusions 5a and 5b are formed on the upper and lower inner edges of the hole 3. These protrusions 5a and 5b are not formed on the side surface of the base at the upper and lower inner edges of the hole 3. Also,
A lid 4 is provided in the hole 3. This lid 4
The external dimensions of the hole 3 are slightly smaller than the internal dimensions of the hole 3, and the stepped portions 8a, 8 formed at the upper and lower ends of the hole 3 are
b engages with each of the protrusions 5a and 5b of the hole 3.

In the upper base body 1, the stepped portions 6 and 7 are formed in the cross-sectional shape shown in FIG. That is, the upper surface portion 1 of the upper base 1 to which the upper covering material 26 is attached
0 is made lower by the thickness e of the mount 26b with respect to the highest surface 9 to which the lower covering material 24a is attached.
With respect to this upper surface portion 10, the stepped portion 7 has an upper covering material 26
The stepped portion 6 is further made lower than the stepped portion 7 by the thickness d of the lower covering material 24a. The mount 26b is provided to adjust the end of the upper covering material 26 to a predetermined size. The upper sheathing 26 has a mount 26 at its end.
The portion of the upper covering material 26 located below the mount 26b is placed on the stepped portion 7. In addition, the lower covering material 2
4a is attached from the side surface to the upper surface of the upper substrate 1 prior to attaching the upper covering material 26, and its end portion is placed within the stepped portion 6. For these reasons, the upper covering material 26 and the lower covering material 24a are attached so as to be substantially smooth on the upper surface of the upper substrate 1.

Note that the stepped portions 6 and 7 shown in FIG.
They are similarly formed in the vicinity of the other side surface and in the vicinity of both side surfaces of the lower base body (not shown). Furthermore, the shape of the vicinity of the corner 2 shown in FIG.
The same structure is also formed near other corners of the lower base body (not shown).

FIGS. 4A and 4B and 5A and 5B are diagrams showing the process of applying the covering material to the accessory case.

The lower covering materials 24a, 24b attached to both left and right side surfaces and corners of the upper base 1 are tacked as shown in FIG. 4A, and cut to a predetermined size by die cutting. Covering material 24 formed into a sheet shape using cloth, natural or synthetic leather as a material
An adhesive surface 31 is formed on the back surface of a, and easy-to-peel mounts 32a and 32b are attached to this adhesive surface 31. The range of the mount 32a located at the center of the adhesive surface 31 of the lower covering material 24a is approximately equal to the shape of the side surface of the upper base 1.

When attaching this lower covering material 24a to the side surface of the upper substrate 1, as shown in FIG. 4B, only the mount 32a is peeled off from the adhesive surface 31 of the lower covering material 24a. The adhesive surface 31 exposed in the exposed portion is attached to one side surface of the upper base 1. Next, the mount paper 32b is peeled off from the adhesive surface 31, and the adhesive surface 3 of the part where the mount paper 32b has been peeled off is
1 is attached to the inside side 1a, front surface, and back surface of the upper base 1. Furthermore, the portion of the adhesive surface 31 that protrudes from the side surface of the upper substrate 1 toward the upper surface is bent toward the upper surface and attached.

As shown in FIG. 5A, the dimensions of the lower covering material 24a are such that the bent ends of the upper surface, front surface, and back surface (the back surface is not shown) of the upper base are within the stepped portion 6 shown in FIG. It is located in. The vicinity of the end of the covering material 24a bent from the side surface side to the upper surface side and the cross section side has a corner portion 2.
7, wrinkles 41 are generated. This is because the corner portion 27 has a three-dimensional curved surface, whereas the covering material 24a is formed in a flat shape. The wrinkles 4 generated near the corners 27 of the covering material 24a in this way
1 is inserted into the hole 3 formed in the upper base 1.

In this state, the lid 4 shown in FIG. 1 is fitted into the hole 3. The size and shape of the lid 4 are such that it fits into the hole 3 with the wrinkles 41 of the covering material 24b inserted into the hole 3 sandwiched between the crease 41 and the inner circumference of the hole 3. The wrinkle 41 is pushed into the hole 3 by fitting the lid 4 . At this time, projections 5a and 5b are provided on the upper and lower side surfaces of the inner peripheral surface of the hole 3.
Since the wrinkles 41 are not formed, the wrinkles 41 are easily pushed into the interior of the base 1 from this portion. As a result, the portion of the covering material 24a located at the corner 27 is pulled into the interior of the base 1 through the hole 3, and the corner 27 of the covering material 24a is fitted to the corner 2 of the upper base 1. It is pasted with.

In this way, by fitting the lid 4 into the hole 3, the covering material 24a can be pulled into the interior of the base 1. There is no need to stretch the covering material 24a, and therefore there is no need to form a protrusion on the covering material 24a. Therefore, the shape of the covering material 24a can be made substantially rectangular, and the covering material can be efficiently cut out from the material.
Material costs can be reduced. Furthermore, the covering material 24a can be standardized to a predetermined size and shape.

Further, the surface of the lid body 4 should be substantially flush with the step 7, and the step difference between the step 6 and the step 7 should be equal to the thickness d of the lower covering material 24a (Fig. 3). ), the lower covering material 24a located at the step 6
flush with the surface of the As shown in FIG. 3, the upper covering material 26 is pasted on the stepped portions 6 and 7, but the stepped portions 6 and 7 are formed substantially flush and smooth near the corners. Therefore, the upper covering material 26
can be adhered to the substrate 1 substantially smoothly.

Note that FIGS. 4A and 4B only describe one side of the upper base body constituting the accessory case.
In FIGS. 5A and 5B, only one corner of one side of the upper base 1 was explained, but the other corner of this side, the other side of the upper base 1, and each corner of the lower base The coating material is adhered in the same way, and the wrinkles that occur when the covering material is adhered are not exposed on the surface of the substrate at any of the corners.

(g) Effect of the invention According to this invention, when a sheet-like covering material is attached to a corner exhibiting a three-dimensional curved surface, wrinkles that occur near the portion of the covering material corresponding to the corner are inserted into the hole. By means of the lid fitting into the hole, the wrinkled covering material can be pushed into the hole, and the covering material located at the corner can be pulled into the base from the hole. This prevents the wrinkles that occur in the covering material from being exposed to the outside of the small item case, making it extremely easy to apply the covering material, reducing costs by improving work efficiency, and reducing the amount of material used. Together with standardization, it is possible to achieve uniform quality.
