Description

  The present invention relates to an information storage medium, and more particularly to a package for storing a disk-shaped (doughnut-shaped) storage disk having a hole in the center.

  For example, storage disks such as hard disks, CDs, and magnetic disks used for computer storage devices, especially hard disks, require extremely high flatness and cleanliness on the surface, and during the manufacturing process. , Never touch the surface.

  The storage disk is transported and stored between processes while being stored in a package, and further subjected to a cleaning process. The storage disk storage package uses a combination of a container main body that stores a large number of disks in a vertical posture, an upper lid that covers the upper surface opening, and a lower lid that covers the bottom surface opening. The plurality of storage disks are held in a safe and non-contaminated state by combining the lid and the lower lid. However, dust and dirt may adhere to the storage disks in the package due to the influence of an unexpected situation. For this reason, the connection between the upper lid and the container main body also prevents the surrounding air from being sucked into the container main body due to fine dust contained in the air, and the vibrations received during the transportation of the package containing the storage disk. It is considered not to cause load collapse due to impact.

  As a measure for preventing the storage disk from collapsing due to vibrations and shocks received during transportation, Patent Document 1 discloses that a magnetic disk storage container includes a container body (storage body), an upper lid (lid), and a lower lid (bottom). The lower lid is attached to the lower opening of the container body, the magnetic disk is inserted into the disk holding groove of the container body, and the upper lid is placed on the upper part of the container body so that the upper opening of the container body and the front and rear notches The upper lid is coupled to the container main body by covering the portion. However, in the magnetic disk storage container of Patent Document 1, the upper lid is formed with two pressing plates extending downward while extending the distance from each other. The magnetic disk inserted into the holding groove of the main body is strongly suppressed from above by the pressing plate, and the collapse of the load due to vibration during transportation is prevented.

  Further, Patent Document 2 shows an example in which two opposing strips having a reverse V-shaped cross section are provided on the upper lid, which are removable and hold the hard disk from above by its own elasticity. In addition, it is described that a hard disk support piece is provided for holding both shoulder portions of the hard disk in a resiliently biased state.

  Recently, however, hard disks have a large capacity and have been trending toward compactness, and higher density and higher performance have been demanded. Adhesion of has become unacceptable.

  The hard disk fixing method described in Patent Documents 1 to 3 is basically a method of elastically pressing the hard disk by providing a pair of elastic overhang portions on the upper lid so that the disk does not move in the container body during transportation. However, in Patent Document 4, conversely, it is pointed out that there are many fine particles adhering to the place where the elastic overhanging portion is in contact with the disk. Further, it is described that such an overhanging portion is eliminated and an upper lid that has a smooth surface on the inner surface side and covers the container main body with a gap from the hard disk is used.

Certainly, it is difficult to fix the hard disk by simply pressing the elastic overhang provided on the upper lid against the upper edge of the hard disk, but as a matter of fact, just inserting the disk into the holding grooves on both sides of the container body will put it in place. It is difficult to fix and stop movement.

  The problem to be solved is that a plurality of storage disks are fixedly held in a storage disk storage package to prevent the generation of fine particles due to vibrations received during transportation. Simply pressing the pair against the upper edge of the storage disk is not enough to prevent the storage disk from swinging, and it is fixed in place simply by inserting the storage disk into the grooves formed on both sides of the container body. It is difficult to stop the movement.

  In the present invention, the storage disk accommodated in the container body is supported at three points of the holding grooves on both sides of the container body and the notches of the upper lid, and further, the storage discs are held downward on both sides of the notches of the upper lid. The most important feature is that the elastic disk protruding in a letter shape is pressed against the storage disk to fix the storage disk at a fixed position.

  The storage disk storage package according to the present invention has a storage disk stored in the container main body, which suppresses the shake in the column direction at three points of the holding groove on both sides of the container main body and the notch of the upper lid, and further, the shoulder portions of the storage disk are Since the elastic protrusion is restrained by the elastic protrusion protruding in the shape of a letter, the elastic protrusion only needs to substantially suppress the deflection in the radial direction. Supporting stability, there is an effect that fine particles are not generated even when subjected to vibration during transportation, and the surface of the storage disk can be kept clean.

  In addition, since the container body is a bottomless, lidless synthetic resin container, it is affected by distortion during molding, causing problems that warpage occurs on both side surfaces and the space between both side surfaces expands. By projecting the lower end edge of the protruding edge in the middle-high shape, or by forming the upper lid itself to bend in a curved shape in the length direction, the distance between the side surfaces of the container body is increased. However, the storage disk is pushed down to the middle and high portions of the elastic protrusion, and the swing of the storage disk inserted into each groove is prevented. Further, the elastic protrusion edge can be supported by being pressed individually for each storage disk by providing a fine cut.

  The purpose of preventing the generation of fine particles due to friction between the package and the storage disk accommodated in the package was realized by improving the shape and structure of the upper lid portion of the container body.

  An embodiment of a storage disk storage package according to the present invention will be described below with reference to the drawings. In FIG. 1, the storage disk package of the present invention is a synthetic resin molded product comprising a combination of a container body 1, a lower lid 2, and an upper lid 3.

  In FIG. 2, the container body 1 is a bottomless, lidless rectangular container for storing, for example, disk-shaped (doughnut-shaped) hard disks as storage disks in a row in the longitudinal direction, and substantially both side portions on the long side. 4 and both end surface portions 5 on the short side, and insertion grooves 6 are opened in both end surface portions 5.

  The insertion groove 6 is a notch whose upper edge is opened, and is an opening for taking in and out a robot arm (not shown) as an extraction means in an automatic processing process of a storage disk. In FIG. 3, the lower lid 2 closes the lower surface opening of the container body 1, has a rectangular dish shape, and has rising edges 7 for fitting the lower surface opening edges of the container body 1 on both sides and both end edges. is doing. 3 is formed between the rising edges 7 on both sides. The fixing hook 11 is a protrusion that protrudes horizontally in front of both end faces. As will be described later, the fixed hook 11 is for hooking a movable hook 12 provided at the lower end of the end surface cover 8 of the upper lid 3 to integrally couple the upper lid 3 and the lower lid 2 to the container body 1.

  In FIG. 4, the upper lid 3 includes a lid portion 13 that covers the upper surface opening of the container body 1 and an end surface cover 8 that covers the insertion grooves 6 on both end surfaces of the container body 1. The lid portion 13 closes the upper surface opening of the container body 1, and the end surface cover 8 extends at right angles from both ends thereof and is formed integrally with the lid portion 13. The upper lid 3 has falling portions 9 that are fitted to the upper edges of both side surface portions 4 of the container body 1 at both side edges thereof.

  The end surface cover 8 is applied to the outer surface of the both end surface portions 5 and 5 of the container main body 1 and closes the insertion groove 6 opened in the both end surface portions 5 and 5 from the outside. On the plate surface of the end surface cover 8, a projecting portion 10 that bulges inward in the shape of the opening shape of the insertion groove 6 is formed.

  When the container body 1 is covered with the upper lid 3, the protruding portion 10 is dropped into the insertion groove 6, fitted and seated in the insertion groove 6, closes the opening of the insertion groove 6, and the direction of the lid The insertion groove 6 is sealed after the lid is applied.

  The upper lid 3 is detachably coupled to the container body 1. In the present invention, a movable hook 12 that hooks on the fixed hook 11 is integrally provided on the lower edge of the end surface cover 8. The movable hook 12 is formed in a thin portion of the end surface cover 8, and is expanded or restored using the elasticity of the material of the end surface cover, and is engaged with or detached from the fixed hook 11. Further, as shown in FIG. 4D, a part of the end surface cover 8 penetrates a part of the end surface cover 8 as shown in FIG. An arcuate slit 17 is formed, or an arcuate recess 17a notched to a certain depth is provided on the back surface side of the end surface cover 8 as shown in FIG.

  If a slit 17 penetrating the front and back of the cover 8 is provided in a part of the end cover 8, the elasticity of the end cover 8 is improved, and the movable hook 12 can be easily engaged with and detached from the fixed hook 11. . However, the slit 17 does not necessarily have to be penetrated, and even if it is the recess 17a, it is possible to ensure the end face cover 8 with the flexibility necessary to engage and disengage the movable hook 12 from the fixed hook 11. Rather, since the front surface of the end surface cover 8 is closed, there is no possibility of dust entering the container body 1, and furthermore, the occurrence of cracks and chipping of the end surface cover 8 can be reduced.

  Disk holding grooves 15 are formed in rows on the inner surfaces of the side surface portions 4 of the container body 1 as shown in FIG. The disk holding groove 15 is a groove for holding a plurality of storage disks D accommodated in the container main body 1 in an upright posture at regular intervals so as not to contact each other. It is held across the holding groove 15.

  In FIG. 5, a longitudinally central portion of the upper lid 3 has a notch 14 that supports a part of the upper edge of the storage disk D held in the disk holding grooves 15, 15, and downwards on both sides of the notch 14. An elastic projecting edge 18 is formed so as to project in a U-shape. The notch 14 further receives the upper edge portion of the storage disk D received in the insertion grooves 6 on both sides of the container body 1 by applying the container body 1 with the upper lid 3. The edge 18 retains the elasticity of the material of the upper lid 3, and is an end edge of the overhanging portion, and presses both shoulder portions of the storage disk D with the end edge across the notch 14.

  The lower lid 2 is fitted to the lower edge of the container main body 1, the upper portion of the container main body 1 and the front and rear openings are covered with the upper lid 3, and the movable hook 12 of the end surface cover 8 of the upper lid 3 is coupled to the fixed hook 11 of the lower lid 2. Thus, the container body 1, the lower lid 2 and the upper lid 3 are integrally coupled. When the container body 1 containing the storage disk D is covered with the upper lid 3, the protruding portions 10 of the cover 8 on both ends of the upper lid 3 are dropped between the insertion grooves 6 of the container body 1 to open the upper surface opening of the container body 1. The upper cover 3 is covered and both the insertion grooves 6 are closed with the end surface cover 8, and the upper cover 3 is pressed down as it is.

  By this operation, the movable hook 12 is pushed up to the fixed hook 11 against the elasticity of the end surface cover 8, and then the movable hook 12 gets over the fixed hook 11 and is locked to the fixed hook 11. An upper lid 3 is further integrally coupled to the assembled lower lid 2, and the container body 1 is sealed. As a result, the storage disk D is held by the three-point support of the disk holding grooves 15 and 15 and the notch 14 on both side portions and the upper edge portion, and the movement in the row direction (longitudinal direction of the container body) is stopped. Further, both shoulder portions of the storage disk D are pressed from the elastic protrusions 18 with the notches 14 interposed therebetween, and the movement in the radial direction is stopped and stably held.

  By attaching the lower lid 2 to the container main body 1, the container main body 1 becomes a bottomed box, and a plurality of storage disks D are carried into the container main body 1 while being collectively held by a robot arm (not shown). . At this time, the robot arm is inserted into the insertion groove 6 of the container body 1 from above, and the storage disk D is inserted into the interior from the upper surface opening of the container body 1 while being supported by the robot arm. It is fitted and held in the corresponding disk holding grooves 15 and 15. Thereafter, the robot arm is pulled out leaving the storage disk D in the container body 1.

  In FIG. 5, reference numeral 16 denotes a positioning notch provided in the container body 1. The notch 16 is used for positioning during conveyance by fitting a part of the conveyor when the container body 1 with the lower lid 3 removed is conveyed along the conveyor line. In addition, since the container main body 1, the lower lid 2, and the upper lid 3 are synthetic resin molded products, countermeasures against static electricity are required. For this reason, for example, at least one of resin fibers such as stainless fibers, Ni fibers, Cu fibers, carbon fibers coated with Ni, Cu, or Al or a combination thereof is blended in the molding resin of the container body 1. Furthermore, a conductive agent such as an antistatic agent or carbon black can be blended in the molding resin as necessary. In addition, a conductive polymer layer such as polypyrrole, polyaniline, or polythiophene may be coated on the surface of the synthetic resin molded product.

  The cross-sectional shape of the elastic protrusion 18 is preferably a horizontally long rectangle as shown in FIG. 6 (a), and is preferably tapered downward as shown in FIG. 6 (b). Since the elastic protrusion 18 is used to hold the storage disk D from above by using the elasticity of the material of the upper lid 3, if the wall thickness is thin, the strength required to hold down the storage disk D cannot be obtained. In addition, it cannot keep itself in a certain posture, but by tapering a taper and changing its thickness, the strength of the base of the elastic ridge 18 is secured and the shape of the letter C is constant. The tip of the disk is kept flexible, and when it comes into contact with the storage disk D, it follows the curved edge of the storage disk and easily adapts to its shape. The holding range keeps the applied pressure and contacts a part of the outer edge of the storage disk D, the holding power of the storage disk D is improved, and even if the container body 1 vibrates during transportation, the internal storage disk D is not shaken. Even if it is not born and is subjected to vibration during transportation, the container body 1 and memory No generation of fine particles due to rubbing between the disc D, thus maintaining the surface of the storage disc D clean.

  Moreover, since the container main body 1 is a synthetic resin molded product, there is a problem that warpage occurs during resin molding and warpage occurs on both side portions of the container main body 1. That is, the container main body 1 has no bottom and no lid, and the left and right side surface portions 4 and 4 are connected by the end surface portion 5 in which the insertion groove 6 is opened. Therefore, although the distance between the left and right side surface portions is supported exclusively by the strength of the end surface portion 5, there arises a problem that the distance between the central regions between both side surface portions that are not affected by the support strength by the end surface portion 5 increases. . FIG. 7 shows an example in which a protruding edge 19 is further provided in a specific region in the central portion of the elastic protruding edge 18 in the length direction so that the elastic protruding edge 18 is formed in a middle-high shape.

  When the distance between the left and right side surface parts 4 and 4 is increased, the storage disk D inserted into the container body 1 is inserted deeply into the container body 1. The middle and high protruding edges 19 formed on the elastic protruding edges 18 are used to press-contact both shoulder portions of the storage disk D that are deeply inserted into the central region of the side faces 4 and 4 having a large degree of spread due to warping. It is. In FIG. 7, the projecting height of the middle-high-shaped projecting edge 19 is emphasized, but the actual projecting height may be about 3 mm with respect to the total length 170 mm of the elastic projecting edge 18. In a state where the container body 1, the lower lid 2 and the upper lid 3 are combined, if the elastic protruding edge 18 is in contact with the storage disk D by about 1 mm (actually, the tip shape of the elastic protruding edge 18 is the storage disk Deforms along the shape of D.) Sufficient.

  FIG. 8 shows an example in which a slit 20 is added to the elastic protrusion 18. The slit 20 is a cut formed over a range of a certain depth from the lower end edge of the protruding edge 19 of the elastic protruding edge 18. The position of the slit 20 is preferably formed between adjacent storage disk holding grooves 15 and 15 formed in a row in the container body 1. A force possessed by a part of the elastic protrusion 18 separated by each slit 20 by applying a cut to the elastic protrusion 18 acts on each storage disk D individually, so that two or more adjacent storage disks D, D are formed. It is no longer pressed by the same force, and is particularly effective when applied to an elastic protrusion having a medium-high protruding edge.

  In addition, the inconvenience caused by the warpage generated on the side surface portions 4 and 4 of the container body 1 can be eliminated by changing the shape of the upper lid 3. FIG. 9 shows an example in which the upper lid 3 is formed into a bent shape with warping with both ends facing upward. By forming the upper lid 3 into a curved shape, the elastic protrusion 18 on the lower surface of the upper lid 3 follows the shape of the warp of the upper lid 3 so that the lower edge is formed in a middle-high shape. If the upper lid 3 is attached to the container main body 1 while keeping the warped shape of the upper lid 3, the elastic protruding edge 18 protrudes into the container main body 1 in a middle-high shape, and the protruding edge deeply in the central region of the container main body 1. The shoulder of the inserted storage disk D is suppressed, and the swing of the storage disk D due to warping of the container body 1 is prevented. Also in this case, it is convenient to provide the slit 20 in the same manner as the elastic protrusion shown in FIG.

  In the above embodiment, an example of a package for storing a storage disk having a constant outer diameter has been described. However, the present invention provides two or more types of storage disks that selectively store two or more types of storage disks having different sizes. The same can be applied to a disk box having a disk holding groove. 10a and 10b, in the container body 1, a first holding groove 15a into which the large-diameter storage disk D1 is inserted and a second holding groove 15b into which the small-diameter storage disk D2 is inserted are arranged in the longitudinal direction of the container body 1. Although a state where two types of large and small storage disks D1 and D2 are accommodated in the container main body 1 is illustrated, the large-diameter storage disk D1 or the small-diameter storage disk D2 is selectively accommodated. Thus, as shown in FIG. 10b, large and small storage disks are not simultaneously stored without distinction. The same applies when two or more types of storage disk holding grooves are provided.

  The upper lid 3 is formed with notches 14 for supporting a part of the storage disks D1 and D2 held in the disk holding grooves 15a and 15b, and elastic protrusions 18 on both sides thereof. The large and small storage disks D1 and D2 accommodated in the container main body 1 have the same upper edge support height, and therefore the storage accommodated in the container main body 1 is not distinguished as shown in FIG. The disks D1 and D2 are commonly received by the notch 14 of the upper lid 3 that covers the container body 1, and the storage hooks 12 of the end cover 8 are joined to the fixed hooks 11 of the lower cover 2 by connecting the storage disks D1 and D2. D2 is supported by the disk holding groove 15a or 15b and the notch 14 at both side portions and the upper edge portion thereof, and is restrained by the pair of elastic protruding edges 18 so that no vibration is generated even when subjected to vibration. The generation of fine particles due to rubbing between packages is prevented.

  A plurality of storage disks such as magnetic disks, CDs, and hard disks used as an external storage device of a computer are stored in an aligned manner, and the performance of the stored storage disk can be maintained at a high level as a package that is transported between processes.
