Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a case of a disk-shaped storage medium such as a compact disc, a floppy disc, an optical disc, a mini disc, etc., which can be made thin with one hand (finger) while it is placed flat. The lid of the case can be opened just by pushing it, and the manufacturing process has been simplified so that it can be used as a packaging case when selling discs.

[0002]

[Prior Art]

 A conventional disc case has a main body and a lid that are separate bodies, which are engaged with each other at the rotating part to form a container, and in the case of a compact disc case, an insole plate for fixing the disc is incorporated. It was Then, the closed state is maintained by engaging the concave portion of the lid with the protrusion provided on the side surface or the front surface of the main body. Therefore, in order to open the lid, I had to pry open the lid with both hands.

Further, as disclosed in Japanese Utility Model Laid-Open No. 1-66392, there is also one in which a lid opening spring is incorporated so that the lid can be opened with one hand.

On the other hand, in a large-sized disc case intended to store a large number of compact discs one by one in a storage bag inside the case, the lid can be opened and closed with a push button with one hand. Some of these products are also on the market.

[0005]

[Problems to be solved by the device]

 With the conventional type, the lid cannot be opened without holding it with both hands, and in order to take out the compact disc inside, you have to change the holding position of the hand multiple times, and simply take out the compact disc from the case. Because of that work, it was extremely troublesome work. Also, when the case was dropped onto the floor with a momentum, the assembled case was easily disassembled into pieces and easily damaged.

[0006] Further, in the device disclosed in the above publication, the lid can be opened with one hand, so that further progress is admitted, but it cannot be opened without holding it by hand. For example, it was not possible to open the lid with one hand while the disc case was placed flat on the desk.

In recent years, the opportunities for using compact discs in automobiles have increased, but it is inconvenient unless the lid can be opened with one hand, especially in automobiles, and the disc case can be placed on a seat or the like. It is preferable for safe driving if you can easily open the lid and take out the disc even if you feel it while leaving it.

On the other hand, the above-mentioned commercially available products are intended to store and store a large number of compact discs and not to carry the case, so that the case itself is large and heavy, and a large number of parts are required. It was assembled from, and the manufacturing process was complicated. In order to take out the compact disc from the storage bag inside, it is necessary to hold the case with one hand and take out the compact disc from the storage bag with the other hand. It was not possible to open the lid with one hand and then take out the compact disc inside with that hand. In addition, such a case is intended to sell the case alone, and was manufactured for a purpose different from the case used when selling a disc which is generally used in the past. Therefore, it was unsuitable for general use as a packaging case for selling discs in terms of size and manufacturing cost.

It should be noted that, for example, one having a holding mechanism for holding the closed state of the lid portion by engaging a part of the main body portion with the lid portion and releasing the holding mechanism by the release button is an example. For example, it is also used in cosmetic containers and travel bags. However, these have an opening button on the side, and they cannot be pushed with one hand when placed flat. None of these are intended to operate the opening and closing of the lid with one hand or one finger.

[0010]

[Means for Solving the Problems]

 That is, in order to easily handle the compact disc in the automobile, it is necessary to open the lid with one hand while the disc case is left flat on the seat of the automobile. There is. In addition, one or two storage sheets are sufficient for use as a packaging case for selling discs, but the case does not become large for convenience of transportation and display, and it seems to be used conventionally. Like the case, it must be thin and lightweight, the manufacturing process is simple, and the manufacturing cost is low.

Therefore, in order to solve the above-mentioned problems, the thin disk case according to the present invention is such that the main body part and the lid part are opened and closed by the connecting part, and a part of the main body part and a part of the lid part are engaged with each other. In the case that has a holding mechanism that holds the closed state of the lid part, the main body part and / or the lid part is provided with a disk storage part, and the main body part, the connecting part, and the lid main part are connected by the connecting part. The lid is integrally molded with synthetic resin so as to give elastic force in the direction of opening from the main body, and an opening button is provided on the upper surface of the main body so that the holding mechanism can be released by operating the opening button. In addition, a plurality of holding mechanisms are provided.

[0012]

[Action]

 The disc accommodated in the accommodating portion is retained in the accommodating portion by the center ribs and peripheral ribs for disc engagement provided on the main body and the lid. The lid is held by the main body with the lid closed by the holding mechanism to protect the disc. By providing the plurality of holding mechanisms, the lid is held smoothly and securely by the main body.

When the case is laid flat so that the lid is up with the lid closed, the release button provided on the upper surface of the main body, that is, on the same surface as the accommodating portion of the main body, also faces upward. become . When the release button is pushed down from above, the plurality of holding mechanisms are released at the same time, and the lid is lifted so as to be opened from the main body. The lid is molded by giving an elastic force in the opening direction from the main body, that is, the lid and the main body are molded so as to be in a flat state. The part comes to be lifted from the main part.

The disk stored in the storage section is locked by the center ribs and peripheral ribs for locking the disk provided in the storage section, and the disk may drop from the storage section even if the lid is opened. No matter what, the stored state is maintained.

[0015]

【Example】

 Next, an embodiment of a thin disk case according to the present invention will be described with reference to the drawings.

Example 1 Case for Two Compact Disks will be described with reference to FIGS. 1 to 5. Reference numeral 1 is a main portion of the thin main body, and 2 is a main portion of the thin lid. The main body portion 1 and the main lid portion 2 are integrally formed of polypropylene so that the connecting main portion 3 gives an elastic force in the direction in which the main lid portion 2 opens from the main body portion 1. For example, if the main body portion 1, the connecting portion 3, and the lid main portion 2 are formed in a flat open shape, the lid main portion 2 is naturally given elastic force in the opening direction from the main body portion 1. Become.

Reference numeral 4 denotes a hinge portion that rotatably connects the connecting portion 3 and the main body portion 1 or the connecting portion 3 and the main lid portion 2. This portion actually connects the main lid portion 2 to the main body portion. It has elastic force in the opening direction from 1. When the synthetic resin material is polypropylene, if the thickness of the hinge portion 4 is about 0.2 mm to 0.3 mm, the elastic force is just good.

Reference numeral 5 denotes a storage part integrally formed with the main body part 1 and the main cover part 2. The storage portion 5 is formed by a bottom surface portion 6 and an outer peripheral portion 9 which is an outer periphery of the main body 7 or the lid 8. The storage portion 5 has a size capable of storing a compact disc in a flat state, and the depth of the outer peripheral portion 9 is substantially the same as the thickness of the compact disc.

Reference numeral 10 denotes an outer peripheral rib which comes into contact with the outer circumference of the compact disc to be stored and which holds the compact disc, and is integrally formed so as to stand up independently from the bottom surface portion 6. The outer peripheral rib 10 is formed to have the same height or lower than the upper end surface of the compact disc to be housed, and has some elasticity due to the elasticity of polypropylene.

Reference numeral 11 denotes a center rib that is just inserted into a central hole of a compact disc to be stored and locks the compact disc. The center rib 11 is also integrally formed in a radial shape so as to rise from the bottom surface portion 6, and is formed to have the same height as or lower than the upper end surface of the compact disc to be housed, and due to the elasticity of polypropylene, it is slightly elastic. Have.

Either the outer peripheral rib 10 or the center rib 11 may be provided, or both may be provided at the same time. In any case, the stored compact disk does not have to fall from the storage section 5.

Reference numeral 12 denotes a concave groove formed on the bottom surface 6 so as to be lowered by one step so that a fingertip (or a toe) can be hooked on the compact disc when the compact disc is taken out. The depth of the groove 12 may be such that the fingertip (or the tip of the fingernail) is caught on the compact disc, and the shape thereof may be any shape such as an oval or a perfect circle, and the number may be appropriately set.

Reference numeral 13 is a straightening rib formed vertically at the four corners of the bottom portion 6 of the main body portion 1. When the lid main portion 2 is bent at the hinge portion 4 of the connecting portion 3, the straightening rib 13 is formed on the lid main portion 2. The main body 1 and the lid main portion 2 are brought into contact with the inner four corners of the outer peripheral portion 6 so that the main body portion 1 and the lid main portion 2 are combined with each other without any deviation so that they accurately overlap each other.

Next, the holding mechanism 14 that holds the closed state of the lid portion 8 by engaging a portion of the main body portion 7 and a portion of the lid portion 8 will be described. As for the lid portion 8, the engaging hooks 15 are integrally formed with the lid main portion 2 at two locations.

On the other hand, the body portion 7 is provided with a slide lever 17 having slide hooks 16 which can be engaged with and disengaged from the engagement hooks 15, formed at two positions. A coil spring 18 for returning the slide lever 17 is provided at one end of the slide lever 17, and a slope portion 19 is formed at the other end in a slanted manner. The slope portion 19 is in contact with the slanted pressing portion 21 of the release button 20. The release button 20 is provided with a coil spring 22 for returning the button.

Further, in order to fix these positions, the holding mechanism cover 23 is arranged so as to cover them. The holding mechanism cover 23 has two through holes 24 for entering the engaging hooks 15. Each part of the holding mechanism 14 is molded separately from the main body part 1. It is also possible to use harder resin, molded products, or steel products, and it is possible to improve locking accuracy and certainty. Further, the attachment of each part of the holding mechanism 14 and the holding mechanism cover 23 to the main body main part 1 can be improved in workability by providing a reverse taper portion in terms of molding so that it can be fitted and eliminated.

The release button 20 may be made slightly larger so that it can be easily operated even in the dark or by groping, and may be set to a height such that it slightly protrudes from the protective cover 23. Note that either one of the coil springs 18 and 22 can be operated.

[Embodiment 2] Case for one compact disc Basically, it is the same as the above-mentioned embodiment 1, but it is suitable for selling one by one. Parts different from the first embodiment will be described with reference to FIGS. 6 and 7.

A compact disc storage portion 5 is integrally formed with the main body portion 1. The storage part 5 is not provided in the main part 2 of the lid. Inside the main lid portion 2, there is provided a pocket 25 for storing lyrics cards. The pocket 25 can be provided by adhering a pocket piece 26 of an arbitrary shape to the inside of the main body 2 of the lid or by fitting it.

[Embodiment 3] Case of two 3.5-inch type floppy disk containing two pieces will be described with reference to FIGS. 8 to 10. Reference numeral 1 is a main part of the thin main body, and 2 is a main part of the thin lid. The main body portion 1 and the main lid portion 2 are integrally molded of polypropylene so that the connecting main portion 3 gives an elastic force to the main lid portion 2 in the direction of opening from the main body portion 1. For example, if the main body portion 1, the connecting portion 3, and the lid main portion 2 are formed in a flat open shape, the lid main portion 2 is naturally given an elastic force in the opening direction from the main body portion 1. Become.

Reference numeral 4 denotes a hinge portion that rotatably connects the connecting portion 3 and the main body portion 1 or the connecting portion 3 and the main lid portion 2. This portion actually connects the main lid portion 2 to the main body portion. It has elastic force in the opening direction from 1. When the synthetic resin material is polypropylene, if the thickness of the hinge portion 4 is about 0.2 mm to 0.3 mm, the elastic force is just good.

Reference numeral 5 denotes a storage portion integrally formed with the main body portion 1 and the lid main portion 2, and the storage portion 5 is formed by an outer peripheral portion 9 and a bottom surface portion 6. The storage section 5 is shaped so that the 3.5-inch floppy disk can be stored in a flat state, and the depth of the outer peripheral portion 9 is the same as the thickness of the 3.5-inch floppy disk. There is.

Reference numeral 10 denotes an outer peripheral rib integrally formed so as to be discontinuous with the outer peripheral portion 9 and rise independently of the bottom surface portion 6. The tip of the outer peripheral rib 10 is formed so as to have the same height or lower than the upper end surface of the outer peripheral portion 9, and has some elasticity due to the elasticity of polypropylene.

Two outer peripheral ribs 10 are formed on opposite sides at opposite positions, and one outer peripheral rib 10 has a protrusion that increases in the amount of invasion into the storage portion 5 side with increasing distance from the bottom surface portion 6. I am doing it. On the other outer peripheral rib 10, there is formed a protrusion having a constant amount of entry into the storage section 5. The outer peripheral rib 10 is not limited to such a shape, and may be formed so as to rise independently from the bottom surface portion 6 so as to have elasticity, and the protrusion itself should also have a shape having elasticity. Good.

It should be noted that the protrusions may have their upper ends cut obliquely when inserting the floppy disk into the storage portion 5 from above so that the outer peripheral ribs 10 can be easily spread.

The portion where the outer peripheral rib 10 rises from the bottom surface portion 6 has to have a certain area within the range where the outer peripheral rib 10 has appropriate elasticity, and it is necessary to consider elasticity and durability as well. And, it is necessary to have a movable amount that can press the stored floppy disk within a range of about 1 mm at maximum. As shown in FIG. 8, if the outer peripheral ribs 10 are provided so as to face each other, the amount of movement on one side can be half.

Reference numeral 27 denotes a protective stopper, which is formed in the vicinity of the outer peripheral rib 10 so as to rise from the bottom surface portion 6, so that the amount of intrusion into the storage portion 5 is smaller than the protrusion of the outer peripheral rib 10 and inside the storage portion 5. The protrusion of the outer peripheral rib 10 is located slightly inside the maximum allowable retracted position. The maximum allowable retracted position is a moving position where the connecting portion between the outer peripheral rib 10 and the bottom surface portion 6 is not damaged even if the outer peripheral rib 10 warps.

This is to prevent the outer peripheral rib 10 from being retracted from the maximum allowable retracted position and damaged by the impact of the stored floppy disk if the case is dropped. .. If the protective stopper 27 is formed, the floppy disk comes into contact with the protective stopper 27 before moving to the position where the outer peripheral rib 10 is damaged, and the outer peripheral rib 10 cannot be retracted any more. Therefore, the outer peripheral rib 10 can be prevented from being damaged.

Reference numeral 28 denotes a correction rib formed vertically so as to face the bottom portion 6 of the main body portion 1 and the lid main portion 2, and rises by a height that is half the width of the connecting portion 3. When the main portion 2 of the lid body is bent at the hinge portion 4, the respective correction ribs 28 come into contact with the connecting portion 3 at an angle of exactly 90 degrees, and the opposing correction ribs 28 also come into contact with each other at that time, The connecting portion 3, the main body portion 1 and the main lid portion 2 are bent accurately at an angle of 90 degrees, respectively, and when the main body portion 1 and the main lid portion 2 are combined into a box-like shape, the main body portion 1 and the main lid portion 2 can be combined without displacement. ..

Next, the holding mechanism 14 that holds the closed state of the lid portion 8 by engaging a portion of the main body portion 7 and a portion of the lid portion 8 will be described. As for the lid portion 8, the engaging hooks 15 are integrally formed with the lid main portion 2 at two locations.

On the other hand, the main body portion 7 is provided with two rotating levers 29. The turning lever 29 is provided with a pressure receiving surface 30 that abuts on the pressing portion 21 of the release button 20 on one side, and a spring abutting surface 32 that abuts on a return spring 31 described later on the other end. A pivoting hook 33 that is engageable with and disengageable from the engaging hook 15 is provided in the central portion. The release button 20 is provided with a coil spring 22 for returning the button.

Then, in order to fix these positions, the holding mechanism cover 23 is arranged so as to cover them. The holding mechanism cover 23 is formed with two through holes 24 for entering the engaging hooks 15, and a return spring 31 for contacting the spring contact surface 32 of the rotating lever 29. .. The return spring 31 is formed by bending a part of the holding mechanism cover 23 at one end and bending it inward to give an elastic force.

Each part of the holding mechanism 14 is molded separately from the main body part 1. It is also possible to use harder resin, molded products, or steel products, and it is possible to improve locking accuracy and certainty. Further, the attachment of each part of the holding mechanism 14 and the holding mechanism cover 23 to the main body portion 1 can be improved in workability by providing a reverse taper portion in terms of molding so that it can be fitted and eliminated.

The open button 20 may be slightly larger in order to make it easier to operate even in the dark or when groping, and may be set to a height such that it slightly pops out from the protective cover 23. It should be noted that either one of the coil spring 22 and the return spring 31 can be operated. It is needless to say that the coil springs 18 and 22 only need to have elastic force, and may be of other types.

Next, the operation of the thin disk case according to the present invention will be described. With the lid 8 open, compact discs and floppy disks can be taken in and out of both the main body 7 and the lid 8. To insert the compact disc into the storage portion 5, the center hole of the compact disc should be aligned with the center rib 11 and simply pushed. Then, the compact disc is pressed and locked by the center rib 11 and the outer peripheral rib 10.

In order to insert the floppy disk into the storage section 5, one of the outer peripheral ribs 10 of the floppy disk may be pushed open and then pushed into the storage section 5. Then, the floppy disk is pressed and locked by the protrusion of the outer peripheral rib 10.

When the compact disc or the floppy disc is stored, the lid portion 8 is rotated so that the engaging hook 15 of the lid portion 8 comes to the position of the through hole 24. When the engaging hook 15 is inserted through the through hole 24, the tip of the engaging hook 15 comes into contact with the tip of the slide hook 16 or the rotating hook 33, and the slide lever 17 or the rotating lever 29 is moved to automatically move. Positively engaged to maintain the lid closed. If the tips of the engaging hook 15, the slide hook 16, and the rotating hook 33 are rounded, this engaging operation is performed smoothly.

Since the engaging hooks 15 are provided at two places, the main body portion 7 and the lid portion 8 are firmly locked in the closed state of the lid. Therefore, even if the main body portion 1 and the main lid portion 2 are formed of a thin material such as polypropylene, and the hinge portion 4 is thin so as to be bendable, it becomes a solid disk case when the lid portion 8 is closed. .. Therefore, the case can be made thin.

Next, when opening the lid, the release button 20 is pressed. When the release button 20 is pressed, the pressing portion 21 of the release button 20 presses the slope portion 19 or the pressure receiving surface 30. In the case shown in FIG. 5, the pressing portion 21 and the inclined surface portion 19 are formed so that their angles are 45 degrees. Therefore, when the release button 20 is pushed downward, the slide lever 17 moves sideways. When the slide lever 17 moves laterally, the engagement between the slide hook 16 and the engagement hook 15 is released. When the engagement is released, since the elastic force is applied to the lid 8 in the opening direction, the lid portion 2 is automatically opened. Then, when the release button 20 is released, the slide lever 17 is automatically returned to the initial position by the coil spring 18, and the release button 20 is also returned to the initial position by the coil spring 22.

Further, in the case shown in FIG. 10, when the pressure receiving surface 30 is pushed downward, the rotating lever 29 rotates accordingly, and the engagement between the rotating hook 33 and the engaging hook 15 is released. .. When the engagement is released, the lid 8 is elastically applied in the opening direction, so that the lid 2 is automatically opened. Then, when the release button 20 is released, the spring pressure surface 32 is pushed downward by the return spring 31, the rotary lever 29 is returned to the initial position, and the release button 20 is also moved to the initial position by the coil spring 22. Will be returned.

[Effect of the device]

 As described above, according to the thin disk case of the present invention, the main body and the lid are opened and closed by the connecting portion, and the main body and the lid are engaged with each other to close the lid. In a case having a holding mechanism for holding a stopped state, a disk storage section is provided in the main body section and / or the lid section, and the main body section, the connecting section and the lid main section are connected, and the lid section is the main body section. It is integrally molded with synthetic resin so that elastic force is applied in the direction to open it, and an opening button is provided on the upper surface of the main body so that the holding mechanism can be released by operating the opening button. Since it is provided at multiple locations, it is possible to prevent the case itself from bending and to ensure the opening and closing. Then, the lid can be opened with one hand while the disc case is left in place, which has the effect of making it extremely easy to take out the disc from the case.

Further, the main part of the main body, the main part of the lid, the disk storage part and the ribs for locking the disk are integrally molded, and the opening / closing mechanism parts can be arranged almost by the slaughter work. The entire case can be made thin, and the manufacturing process can be simplified and the cost can be reduced, so that the case can be used as a packaging case when selling discs.
