Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container for storing optical disks, magnetic disks, and other donut-shaped disks such as wafers and records.

[Prior art]

2. Description of the Related Art Optical disks, magnetic disks, and the like have been rapidly growing as storage media for computers in recent years, and it is desired to provide a container that can store and transport such optical disks, magnetic disks, and the like. In other words, after these disks are manufactured, they must be transported from the manufacturing process to the process of writing information onto the disks. Therefore, consideration has been given to storing the disks using a container as shown in FIG. 10, which is provided in Japanese Patent Publication No. 54-20904. In this case, an insert 31 with a plurality of grooves 33 formed in parallel is placed on the bottom of a box-shaped container main body 30, a plurality of ribs 32 are provided in the vertical direction on the inner surface of the side wall, and the side circumference of the disk 1 is placed between the ribs 32. At the same time, the lower edge of the disc 1 is inserted into the groove 33 of the insert 31 to hold the disc 1, and the support 34 is inserted into the groove 35 provided on the lower surface of the upper part of the disc 1 housed in the container body 30. The upper edge of the disk 1 is inserted and placed, and the upper lid 36 is attached to the upper opening of the container body 30 while pressing the support 34 from above.

[Problem that the invention attempts to solve]

However, in this case insert 3
1 and the support port 34 are formed separately from the container body 30 and the top lid 35, which requires an assembly process, and also causes misalignment of the upper and lower grooves 35 and 33, making it difficult to securely hold the disk 1. Furthermore, since the container body 30 has both ends and walls, it is necessary to grasp the disk 1 with a clamp of an automatic device and take it in and out one by one. Disc 1 is easily scratched because the front and back surfaces of the disc 1 are grabbed, and there is a problem that there is a limit to the number of discs that can be stored because it is necessary to provide a gap between the discs for the clamp to be inserted. .
There is another similar structure as shown in Japanese Patent Publication No. 55-8812, but in this conventional example, as shown in FIG. The upper lid 3 is placed on the top opening of the container body 37.
9, a bag body 40 having pleats formed on the surface is attached to an upper lid 39 on the lower side of the bag body 9, and there is a problem similar to that of the conventional example shown in FIG.

The present invention has been developed in view of the above points, and is capable of reliably holding and transporting disks, without the risk of damaging the disks when taking them in and out, and increasing the number of disks that can be stored. In addition, the elastic means for pressing the disk from above is made up of elastic ribs integrated into the top cover, thereby reducing the number of structural members and preventing the deformation of the elastic ribs from affecting the top cover. The object is to provide a storage container.

[Means for solving problems]

However, the disk storage container according to the present invention is
The inner bottom surface is formed into a downwardly curved arc-shaped surface, and the center of the bottom surface is open, and a plurality of parallel longitudinal directions into which the peripheral part of the donut-shaped disk 1 is inserted and held extending from the inner surface of both side walls to the inner bottom surface. insertion groove 2

The bottom cover 5 covers the bottom opening 4a of the main body 4, and is removably attached to the top opening 4b of the container main body 4, and has elasticity to close the notch 3 from the outside with hanging pieces 11 at both ends. The lower surface of the upper lid 6 is provided with both side pieces 7a and both side pieces 7 located in the direction of both end walls of the container body 4.
The elastic ribs 7, which are formed with a concave cross-section and press the upper edge of the disk 1 housed in the container body 4, are integrally parallel downward in correspondence with each insertion groove 2. At the same time, the thickness of both side pieces 7a of the elastic rib 7 is formed to be thinner than the thickness of the upper lid 6 and thicker than the thickness of the bottom piece 7b. A groove 8 with a downward opening is formed on the lower surface of the bottom piece 7b of the elastic rib 7 so as to be parallel to both side pieces 7a of the elastic rib 7, and the bottom of the groove 8 is directed upward between both ends. The width of the bottom 8a of the groove 8 is approximately equal to the thickness of the disk 1, and the inclination of the inner wall surfaces on both sides of the groove 8 is approximately 60 degrees with respect to the bottom 8a. This invention is characterized by a gentle opening angle in the vicinity, and the disk storage container is formed with such a structure to achieve the above object. Describe.

1 to 9 show an embodiment of the present invention, in which the container body 4 is usually made of opaque synthetic resin, and as shown in FIG.
The inner bottom surface is formed with a downwardly curved arc-shaped surface having the same diameter as the disk 1, and a bottom opening 4a for punching the mold is formed in the center of the inner bottom surface, and both end walls are formed into a U-shape. A cutout 3 for inserting a jig 9, which will be described later, is formed by cutting out the hole, and vertical ribs 10 are formed at equal intervals on the inner surfaces of both sides of the bottom opening 4a, as shown in FIGS. 1 and 2. As shown in the figure, a plurality of ribs are protruded in parallel so as to face each other, and the groove between these longitudinal ribs 10 constitutes an insertion groove 2 into which the side peripheral portion of the donut-shaped disk 1 is inserted and supported. Fourth
The figure shows the cross-sectional shape of the insertion groove 2 and the vertical rib 10, and the width of the bottom 2a of the insertion groove 2 is formed to a dimension that approximately corresponds to the thickness of the disk 1, and the inclination of the inner walls 2b on both sides is It is formed at an angle of approximately 25 degrees with respect to 2a. The bottom lid 5 covers the bottom opening 4a of the container body 4 to prevent dust from entering the container body 4, and is made of soft polyethylene or polypropylene.As shown in FIG. A peripheral wall 5a is provided to project upwardly, and a projecting rib 5b is provided inwardly to project from the upper surface of the bottom cover 5 so as to be parallel to the peripheral wall 5a.
As shown in FIG. 1, between the bottom cover 5 and the protruding rib 5b
The lower end of a peripheral wall 4c integrally protruding from the lower peripheral portion of the container body 4 placed on the upper surface is removably press-fitted and attached to the bottom of the container body 4. The upper lid 6 is made of the same material as the bottom lid 5, and has a peripheral wall 6a integrally protruding from the lower peripheral surface of the upper lid 6, in which the outer peripheral surface of the upper opening 4b of the container body 4 is inscribed, and peripheral walls 6a on both end sides. Hanging pieces 11 are integrally extended from the lower end so as to be inclined inward, and ribs 13 formed at the opening periphery of the notch 3 of the container body 4 are formed on the inner surface of the hanging pieces 11. As shown in FIG. 1, an engaging wall 12 that is inscribed and engaged is provided integrally and protrudes. Further, a plurality of elastic ribs 7 are bulged in parallel in a staggered manner on the lower surface on both sides of the center line connecting both ends of the upper lid 6. These elastic ribs 7 correspond to each insertion groove 2, and have a substantially concave cross section as shown in FIG.
The wall thickness of both side pieces 7a is approximately 1/2 of the wall thickness of
Furthermore, the thickness of the bottom piece 7b is approximately 1/2 of the thickness of the side pieces 7a. In other words, the ratio of the thickness of the top lid 6, the thickness of the side pieces 7a, and the thickness of the bottom piece 7b is 4:
2:1, with the elasticity of the bottom piece 7b being the largest, followed by the elasticity of the side pieces 7a on both sides. Further, the bottom piece 7 of the elastic rib 7 is opened at both ends in the direction of both side walls of the container body 4, and the bottom piece 7 of the elastic rib 7 is arranged so that the groove 8 of the downward opening is parallel to the side pieces 7a of the elastic rib 7.
As shown in FIG. 7, this groove 8 curves the bottom 8a between both ends into an upward arc of the same diameter as the disk 1, so that the upper edge of the disk 1 can be inscribed. It's becoming like that. Also, groove 8
As shown in FIG. 7, the inclinations of the inner wall surfaces on both sides of the bottom portion 8a are set at a gentle expansion angle of approximately 60 degrees.

When storing a donut-shaped disk 1 such as an optical disk, a magnetic disk, or another wafer or record into the container formed as described above, first place the bottom lid 5 on the bottom of the container body 4. Keep it covered. Then, as shown in FIG. 8, a jig 9 is passed through the hole 2 of the disc 1 to hold the plurality of discs 1. In this state, the jig 9 is lowered from the upper opening 4b of the container body 4 by an automatic device, and each disc is The disk 1 is housed in the container body 4 while the side circumferential portion of the disk 1 is inserted and guided into the insertion groove 2. Next, the container body 4
When the jig 9 is removed from the notches 3 provided on both sides of the disc 1, the disc 1 remains within the container body 4 and is held therein. Next, the top cover 6 is removably attached to the top opening 4b of the container body 1 from above to close the top opening 4b, and the hanging pieces 11 are attached to both end walls of the container body 1 as shown in FIG. The open notch 3 is closed. At this time, the upper end periphery of the container body 4 fits into the groove 8 of the elastic rib 7 bulged on the lower surface of the upper lid 6, and comes into elastic contact with the bottom 8a of the groove 8. At this time, since the bottom piece 7b of the elastic rib 7 has a thin wall thickness, an appropriate elasticity can be obtained and the disk 1 can be pressed without wobbling. Further, the thickness of both side pieces 7a of the elastic rib 7 is thicker than the thickness of the bottom piece 7b,
Since it is thinner than the wall thickness of the main body of the upper lid 6, the elastic deformation of the bottom piece 7b is absorbed by the side pieces 7a, and it is possible to prevent the main body of the upper lid 6 from wobbling due to deformation. Furthermore, even if the disk 1 held in the insertion groove 2 is slightly inclined, both inner walls of the concave groove 8 of the elastic rib 7 have a slight inclination of about 60 degrees as described above, so that the disk 1 can be pushed from above. When pressure is applied, the upper end of the disk 1 slides against the inclined inner wall and is guided to the bottom 8a, ensuring that it stands vertically. On the other hand, since the hanging piece 11 is inclined inward and extends, the engagement wall 12 on the inner surface of the hanging piece 11 and the rib 11 formed on the opening periphery of the notch 3 of the container body 4 are connected to each other. are brought into elastic contact by the inward elastic force of the hanging pieces 11, and the notch 3 of the container body 4 can be reliably sealed. In addition, the container body 4
To take out the disc 1 stored in the disc 1, remove the top cover 6, insert the jig 9 into the through hole 1a of the disc 1 through the notch 3, and then lift the jig 9 upward to remove the disc 1. A plurality of disks 1 can be taken out at once.

[Effect of idea]

As mentioned above, in the present invention, the inner bottom surface is formed into a downwardly curved arc-shaped surface, the center of the bottom surface is open, and the periphery of the donut-shaped disk extends from the inner surfaces of both side walls to the inner bottom surface. Since the container body has a plurality of parallel vertical insertion grooves for inserting and holding the disks, the insertion grooves for holding the disks can be integrally formed on the inner bottom surface of the container body without problems such as removing the mold. Therefore, there is no need to attach a separate member to the container body, reducing the number of components and the assembly process.Moreover, there is a jig that is inserted into the through hole of the donut-shaped disk on both end walls of the container body. Since the insertion notch is provided, multiple disks can be stored in the container body at once with the jig passed through the through hole, and the jig insertion notch can be inserted into the through hole of the stored disks. Since the jig can be inserted through the disk, the disk can be removed at once, and there is no need to use a crank to insert and remove disks one by one, so there is no fear of damaging the front or back of the disk, and the automatic device configuration Moreover, there is an advantage that more disks can be stored since there is no need to provide a space for the crank between the storage disks. Furthermore, since it is provided with a bottom cover that fits onto the bottom of the container body and covers the bottom opening of the container body, it is possible to prevent dust from entering through the bottom opening, which is necessary for removing the mold. There is no problem even if there is a bottom opening. In addition, the lower surface of the resin upper lid, which is removably attached to the upper opening of the container body and has the elasticity to close the above-mentioned notch from the outside with hanging pieces at both ends, has the upper edge of the disk stored in the container body. Elastic ribs with a concave cross section to be pressed are bulged downward in parallel in correspondence with each insertion groove, and the thickness of both sides of the elastic ribs is made thinner than the thickness of the top cover and thinner than the thickness of the bottom piece. Since it is formed thickly, when the upper edge of the disk is pressed from above by the elastic rib, the bottom piece of the elastic rib exerts an appropriate elastic force to elastically hold the disk and prevent the disk from wobbling. Moreover, as mentioned above, since the thickness of the side pieces is set relative to the thickness of the top cover and the thickness of the bottom piece, the elastic deformation of the bottom piece can be absorbed by the side pieces, thereby preventing the influence of the deformation from reaching the top cover. As a result, there is an advantage that the deformation of the top lid does not affect the adhesion state, and the top opening of the container body and the jig insertion notch can be reliably closed by the top lid and its hanging pieces. Further, on the lower surface of the base of the elastic rib, there is provided a groove with openings at both ends and the lower surface that engage the upper edge of the disk, and the width of the bottom of the groove is formed to be approximately equal to the thickness of the disk. The inclination of the inner wall surface with respect to the bottom is set to a gentle expansion angle of about 60 degrees, so even if the disc stored in the container body is slightly tilted, the upper edge of the disc will not fit into the groove of the elastic rib when the top cover is attached. There is an advantage that the bottom of the groove can be slid and guided on the wall surface, and the disk can be reliably held vertically.
