Description:

BACKGROUND OF THE INVENTION

This invention relates to a container for containing and transporting hard disks which function as magnetic storage medium for a storage device of a computer. The container may be used for a carrier for processing the disks.

As shown in FIGS. 5 and 6, a prior hard disk container 1 comprises a container body 2 in the form of a rack carrier having a plurality of U-shaped disk receiving grooves 3 provided in an inner surface of the container body 2 in a spaced mannerand in which magnetic hard disks (not shown) are engaged, respectively, and having end openings 4 provided in both ends of the container body 2 to expose central holes of the hard disks therethrough for inserting a tool therethrough and upper and loweropenings provided in upper and lower portions of the container body 2. An upper cover 5 is mounted on the container body 2 at its upper portion to close the upper opening and the end openings 4 and has a positioning protrusion 5a on the upper face ofthe upper cover 5. Also, a lower cover 6 is mounted on the container body 2 at its lower portion to close the lower opening and has a positioning recess 6a to receive a positioning protrusion 5a on an upper cover 5 of a container therebelow as as topermit stacking the hard disk containers upon the other. The upper and lower covers 5 and 6 are loosely mounted on the container body 2.

Although the hard disk container 1 may be discarded after being used only one time or reused after a full cleaning and refurbishing process, it tends to be reused because hard disks have rapidly become cheaper in the same manner assemiconductors. Thus, it will be noted that the hard disk container is required to have durability if it is to be reused.

However, the prior hard disk container has the following various drawbacks. One of them is that the prior container has no air-tightness because the upper and lower covers 5 and 6 are loosely mounted on the container body 2 as aforementioned. Thus, the container breathes due to variation in ambient temperature to cause it to inhale humidity and/or dust to contaminate surfaces of the hard disks which have a mirror-like finish, which probably causes them to vary in physical properties. Thiscauses the hard disks to be ineffectively reproduced and to have little durability.

Another drawback is that the hard disks loosely engage the grooves 3 in the container body 2 because the grooves 3 are formed so wide as to allow the hard disks to be introduced easily into and/or be easily withdrawn out of the sliding grooves 3. Although the upper cover 5 has bracket 56 provided thereon so as to position the hard disks in the sliding grooves 3, it is difficult to engage the brackets with the hard disks because they loosely engage the sliding grooves 3. Thus, the hard disks tendto be contained in the container body 2 in a slightly inclined manner so that they distort the brackets, which causes the durability of the container to be shortened.

A further drawback is that since the upper and lower covers 5 and 6 are frequently removed from the container body 2, it is difficult to mount them on the corresponding container body 2. More particularly, the hard disk container is soconditioned that the upper and lower covers 5 and 6 are removed from the container body 2 when processing the hard disks and are in place only during their transportation and storage. Thus, the container body 2 and the upper and lower covers 5 and 6 areseldom combined with each other after two uses although they are combined at the beginning of use. Since the times of processing use of the container body 2 are different from the times of use of the upper and lower covers 5 and 6, the covers cannot bemounted on the former in an air-tight manner. In order to avoid this problem, an operator should always match the lot numbers indicated on the container body 2 and the covers 5 and 6 of the containers. However, it is troublesome and in addition has lowaccuracy of because the operator matches them with his eyes.

DETAILED DESCRIPTION OF THE EMBODIMENT

Referring to FIGS. 1 through 3, there is shown a hard disk container 1 constructed in accordance with one embodiment of the invention. The hard disk container 1 comprises a container body 2 having a plurality of U-shaped disk receiving grooves 3provided in an inner surface thereof in a spaced manner and receiving magnetic hard disks D, respectively, and having end openings 4 provided in both ends thereof to expose central holes H of the hard disks D therethrough so as to make it possible toinsert a handling tool, not shown, and upper and lower openings provided in upper and lower portions of the container body 2 of the hard disk container 1. As shown in FIG. 2 and FIG. 3, the container body 2 has continuous upper and side sealingprotrusions 2a and 4a integrally provided on the container body 2 at its upper portion and at the portion adjacent to the side openings 4 and a successive lower sealing protrusion 2b integrally provided on the container body 2 at the portion adjacent toits lower opening. The sealing upper and lower protrusions 2a and 2b have sealing upper and lower recesses 2c and 2d provided in the walls of the upper and lower protrusions 2a and 2b at their peripheries to sealingly engage sealing upper and lowerprojections in upper and lower covers described hereinbelow.

An upper cover 5 is sealingly mounted on the container body 2 at its upper portion to close the upper opening and the side openings 4 and has a positioning protrusion 5a on the upper face thereof. A lower cover 6 is sealingly mounted on thecontainer body 2 at its lower portion to close the lower opening and has a positioning recess 6a to engage the positioning protrusion 5a of an upper cover 5 of a next lower container to make it possible to superpose one of the hard disk containers 1 uponthe other. The upper and lower covers 5 and 6 have continuous upper and lower grooves 5b and 6b provided at their peripheries to engage the sealing upper and lower protrusion 2a and 2b of the container body 2. The upper cover 5 also has continuous sidegrooves 5d provided in the portion adjacent to the cover portion covering the side openings 4 to engage the sealing side protrusion 4a of the container body 2. The upper and lower covers 5 and 6 also have sealing upper and lower projections 5c and 6c tosealingly engage the sealing upper and lower recesses 2c and 2d, respectively so as to mount the upper and lower covers 5 and 6 on the container body 2 in an airtight manner.

The upper cover 5 also has a plurality of pairs of inverted Y-shaped brackets 7 detachably provided therein to resiliently engage the hard disks D in the container body 2 so as to position the hard disks D in the sliding grooves 3.

Humidity absorbing means is provided in one of the container body 2 and the upper and lower covers 5 and 6 to abosrb humidity in the hard disk container 1. In the illustrated embodiment, the humidity absorbing means may comprise a U-shapedhumidity absorbing pannel 9 including a humidity absorbing agent such as silica gel coated on a base as shown in FIG. 4, which is introduced into a groove 8 provided in the container body 2 separately from, but similarly to the grooves 3. The humidityabsorbing agent may be coated on the inner surface of at least one of the container body 2 and the upper and lower covers 5 and 6.

A magnetic layer 10 may be provided on the outer surfaces of the container body 2 and the upper and lower covers 5 and 6 to provide the history of process of the container and of its transportation and a protective film of chemical resistancematerial may be coated on the magnetic layer 10 to protect it.

A flange 11 may be provided on the upper cover 5 to help to remove the upper cover 5 from the container body 2 by the operator's finger.

As aforementioned, since the the upper and lower covers 5 and 6 at their successive upper, side and lower grooves 5b, 5d and 6b engage the sealing upper, side and lower protrusions 2a and 2b of the container body 2 while the sealing projections5c and 6c on the walls of the successive upper and lower grooves 5b and 6b of the upper and lower covers 5 and 6 engage the sealing upper and lower recesses 2c and 2d in the walls of the sealing upper and lower protrusions 2a and 2b of the container body2, the upper and lower covers 5 and 6 are mounted on the container body 2 in an air-tight manner and they are never unintentionally removed from the container body 2. Also, since the humidity absorbing agent is provided within the hard disk container inthe form of pannel or in the form of film on the inner face of at least one of the container body 2 and the upper and lower covers 5 and 6, humidity within the hard disk container 1 can be positively removed while the humidity absorbing agent does notinterfere with an automatic machine if the hard disk container is used therein.

Furthermore, since a plurality of pairs of brackets 7 in the form of inverted Y-shape are used on the upper cover 5 so that they resiliently engage the hard disks D within the container1, they can positively hold the hard disks D by mounting theupper cover 5 on the container body 2 after the brackets 7 engage the hard disks D. The magnetic film 10 on the outer surfaces of the container body 2 and the upper and lower covers 5 and 6 serves to make it easy for the operator to know the history ofthe process of the container and its transportation while it is protected by the protective film on the magnetic film 10. Thus, it will be noted that the container can cope with severe management conditions and that even though the container body 2 andthe covers 5 and 6 having substantial difference between the times of their use are combined with each other, it never causes any trouble with the combination.

While an embodiment of the invention has been described and illustrated with reference to the accompanying drawings, it will be understood by those skilled in the art that it is by way of example, and that various changes and modifications may bemade without departing from the spirit and scope of the invention, which is intended to be defined only by the appended claims.
