BEST MODE FOR CARRYING OUT THE INVENTION
An example of the disk case according to the present invention will be described with reference to FIGS.
[0007]
FIG. 1 is a plan view showing a developed state. This disc case is generally made of cardboard. In FIG. 1, the center is a lower lid 1, the left is an upper lid 2, and the right is a storage section 3.
[0008]
The upper lid part 2 is connected to one end of the lower lid part 1 and can be folded back on the lower lid part 1 to be overlapped. In the figure, reference numeral 8a denotes a folding line when the upper lid 2 is folded over the lower lid 1 and overlapped. In addition, a circular outer window 9a is formed substantially at the center of the upper lid 2.
[0009]
The housing 3 is connected to the other end of the lower cover 1 facing the connection side of the upper cover 2. The storage section 3 includes a central receiving section 5 and holding sections 6 and 6 located on both sides of the receiving section 3 with respect to the direction in which the storage section 3 is folded back onto the lower lid 1. The lower lid 1 is connected to the lower lid 1 via a portion 5. The storage section 3 can be folded back onto the lower lid section 1 via the folding line 8b.
Further, the storage section 3 will be described.
[0010]
The receiving portion 5 is a portion on which the disk 4 is mounted, and the holding portions 6 and 6 located on both sides thereof are folded back onto the receiving portion 5 to press the disk 4 mounted on the receiving portion 5. It is. In the figure, reference numerals 8c and 8c denote folding lines when the holding portions 6 and 6 are folded onto the receiving portion 3, and the interval between the folding lines 8a and 8b is slightly smaller than the diameter of the disk 4.
[0011]
As described later, a circular inner window 9b is provided at a substantially central portion of the storage section 3 so that the storage section 3 is folded over the lower lid section 1 and the upper lid section 2 is folded back over the lower lid section 1 to be substantially overlapped. Have been. Further, along the outer periphery of the disk 4 placed on the receiving portion 5 of the storage portion 3, the holding portions 6, 6 are turned from the folding lines 8c, 8c when the folding is performed on the receiving portion 5 to the holding portions 6, 6 side. Slits 7, 7 serving as disk stoppers are provided in a protruding arc shape. This disk stopper is for preventing the disk from shifting and keeping the disk 4 at the mounting position. In the case of the slits 7 shown in the figure, the disk 4 is inserted into the slits 7. The state is prevented from shifting.
[0012]
Next, a procedure for storing the disk 4 in the disk case will be described with reference to FIGS.
[0013]
First, the disc 4 is placed at the position shown by the dashed line in FIG. That is, the disk 4 is placed so that the inner window 9b is concentrically covered and the outer peripheral edge is located along the slits 7,7.
[0014]
Next, the holders 6, 6 are folded back onto the receiving part 5 via the folding lines 8c, 8c, and the loaded disk 4 is pressed from above. In this state shown in FIG. 2, the two holding parts 6, 6 are folded back onto the receiving part 5, so that a part of the disk 4 is automatically inserted into the slits 7, 7. The displacement of the disk 4 in the left-right direction in the figure is prevented by inserting the disk 4 into the slits 7, 7, and the displacement of the disk 4 in the up-down direction in the figure is prevented by the folded holding portions 6. , 6. Therefore, the disk 4 is held at a predetermined mounting position.
[0015]
After the holding portions 6 and 6 are folded back onto the receiving portion 5 as described above, as shown in FIG. 3, the entire storage portion 3 is folded back onto the lower lid portion 1 via the folding line 8b. By the way, a simple cut may be made between the lower lid 1 side end of the holding parts 6, 6 and the lower lid 1, but a gap 10 having a width of 2 mm or more is formed as shown in FIG. Is preferred. This is because, as shown in FIG. 2, when the two holding parts 6, 6 are folded back onto the lower lid part 1, a gap 10 is provided between the ends of the two holding parts 6, 6 and the folding line 8b, and the storage is performed. When the entire part 3 is folded back onto the lower lid 1 via the return line 8b, in order to prevent the ends of both holding parts 6, 6 from coming into contact with the upper surface of the lower lid 1 and making it difficult to return. belongs to.
[0016]
After the holding portions 6 and 6 are folded back on the receiving portion 5 to be in the state shown in FIG. 3, the upper lid portion 2 is further folded back on the lower lid portion 1 and overlapped, and the upper lid portion 2 and the lower lid portion 1 The storage unit 3 is sandwiched. FIG. 4A is a plan view in this state, and FIG. 4B is a schematic front view. In this state, the outer window 9a of the upper lid portion 2 and the inner window 9b of the storage portion 3 shown in FIG. 3 substantially overlap, and the stored disk 4 is confirmed from the outside via the outer window 9a and the inner window 9b. be able to. The outer window 9a and the inner window 9b are not essential, but are preferably provided so that the presence of the disk 4 housed in the disk case can be confirmed from the outside. The outer window 9a and the inner window 9b are usually formed as circular holes of the same size. However, as long as the disk 4 does not protrude, the sizes and shapes of the two windows may be different, and the outer window 9a and the inner window 9b may be triangular, square or other. The shape may be as follows. Further, one or both of the outer window 9a and the inner window 9b can be covered with a transparent material such as a plastic sheet or a film to protect the disk 4 stored therein.
[0017]
The free end side of the upper lid part 2 shown in FIG. 4B is overlapped on the lower lid part 1 (storage part 3), and the free end side is bound to a magazine or a book, so that the disk 4 can be wrapped. The disk 4 can be attached to a magazine or a book without using an adhesive. Binding to a magazine or book can be performed by, for example, azil binding or wireless binding.
[0018]
On both sides of the disc case bound to the magazine or book as described above, the upper lid 2 and the lower lid 1 are merely overlapped, and no sealing with an adhesive or an adhesive is performed. . However, even if a finger or the like is prying between the upper lid part 2 and the lower lid part 1 from the side, the holding parts 6 and 6 are covered on both sides of the disk 4 of the storage part 3, and the disk 4 cannot be pulled out. It cannot be used. Further, for the same reason, there is no possibility that the disc 4 will fall off when being carried. In particular, the deeper the holding portions 6 and 6 cover the disk 4, the more reliably the disk 4 is prevented from being pulled out from the disk case side and prevented from falling off. It is preferable that the width of the cover 4 is not less than 1/2 of the radius of the disk 4 and not more than the diameter (preferably not more than the radius).
[0019]
Perforations and cuts that penetrate the lower lid 1 and the upper lid 2 can be provided along the binding side so that the book disk case bound to the magazine or book can be easily removed from the magazine or book. . Further, perforations or cuts for opening the lower lid 1 or the upper lid 2 to facilitate opening can be provided in the lower lid 1 or the upper lid 2.
[0020]
Further, a case where the present disc case is bound to a magazine or a book will be described.
[0021]
When this disc case is bound to a magazine or book, it is preferable to provide an opening 18 as shown in FIG. The opening portion is a band-like portion sandwiched between two perforations or cuts, and can be opened by being peeled left and right from the center. In FIG. 5, the opening portion 18 is provided on the lower lid portion 1, but may be provided on the upper lid portion 2. Further, a separation line 19 that is a perforation or a cut is formed near the lower lid portion 1 of both holding portions 6. The role of the separation line 19 will be described later.
[0022]
The disc case shown in FIG. 5 is the same as that of FIG. 1 except that it has the opening portion 18 and the separation line 19, and is folded in the same manner as that of FIG. The free end side of the specified upper lid part 2 is overlapped on the lower lid part 1 (storage part 3), and the free end side is bound to a magazine or book, so that the disk 4 is wrapped and attached to the magazine or book. Can be done. At this time, as shown by hatching in FIG. 6A, a binding margin 20 is set on the free end side of the upper lid 2, and the end near the lower lid 1 of the holding unit 6 is set in the binding margin 20. , And it is also preferable to bind them together. FIG. 7 shows a state in which the lower lid 1 and the upper lid 2 are separated by peeling the opening portion 18 shown in FIG. 5 to the left and right, and the opened state is shown in FIG. 7. As clearly shown in FIG. The portion 6 is maintained so as to cover the disk 4, and the holding force of the disk 4 is further improved. Therefore, even when the disc case is made of relatively thin and flexible paper, the disc 4 can be removed by prying a finger or the like between the upper lid section 2 and the lower lid section 1, and the disc 4 may drop off when being carried. Can be prevented.
[0023]
By the way, in the state of FIG. 7, one end (lower side in the figure) of the holding unit 6 is bound to a magazine or a book, so that it is difficult to open the holding unit 6 and take out the disk 4. The separation line 19 provided on the holding section 6 is for releasing the holding section 6 from binding by cutting the holding section 6 along the cutting line 19 and making the holding section 6 easy to open. Although the separation line 19 is not essential, it is preferable to provide the separation line 19 when performing the binding in order to make it easier to take out the disk 4.
[0024]
When the disk case is made of relatively thick and strong paper, as shown in FIG. 8, the gap 10 between the holding portion 6 and the lower lid portion 1 is widened, and as shown in FIG. It is also possible that the holding portion 6 does not cover the 20. In this case, the state in which the unsealing portion 18 shown in FIG. 8 is peeled to the right and left and opened is shown in FIG. 10, and the holding portion 6 is in a free state where it is not bound. It can be opened to take out the disk 4.
[0025]
5 to 10, the same reference numerals as those in FIG. 1 indicate the same components as those in FIG.
[0026]
The disk stopper means in the disk case shown in FIG. 1 has arc-shaped slits 7, 7 bulging from the folding lines 8c, 8c to the holding portions 6, 6 side. However, the disc stopper means of the present invention is not limited to this, and the disc 4 on the receiving portion 5 is shifted in the left-right direction in the drawing in a state where the holding portions 6 and 6 are folded over the receiving portion 5. What is necessary is just what can prevent.
[0027]
The arc-shaped slits 7, 7 are suitable for directly storing the disk 4 in the present disk case. On the other hand, the disk 4 may be stored in the disk case in a rectangular bag 11 (see FIG. 5). In this case, the arc-shaped slits 7, 7 may be used as a disk fixing means without any problem. However, in order to facilitate the storing operation, the hook-shaped slits 7, 7 as shown in FIG. It is preferable to use it as a means. Hereinafter, hook-shaped slits 7, 7 which are other examples of the disk fixing means will be described.
[0028]
As shown in FIG. 11, the disk 4 is housed in a rectangular bag 11. The bag 11 is for protecting the disk 4 and may be of any type. Generally, a bag having a transparent plastic film on one side and a nonwoven fabric on the other side is used. When the disc 4 housed in the bag made of the plastic film and the nonwoven fabric is placed on the receiving portion 5, the plastic film side faces the receiving portion 5 so that the disc 4 can be confirmed through the plastic film from the inner window 9b. Will be placed.
[0029]
The interval between the folding lines 8 c, 8 c when the holding parts 6, 6 are folded onto the receiving part 5 is slightly smaller than the diameter of the disk 4. In addition, the slits 7, 7 protrude from the folded lines 8 c, 8 c of the holding portions 6, 6 on the receiving portion 3 toward the holding portions 6, 6 along the outer periphery of the corner portion of the bag 11 containing the disk 4. It is formed in a hook shape. That is, the bag 11 accommodating the disk 4 is placed with the corners positioned up and down in FIG. 11 so that the corners are along the hook-shaped slits 7.
[0030]
After placing the bag accommodating the disk 4 at the position as shown in FIG. 11 and then folding both the holding portions 6 and 6 onto the receiving portion 5 as shown in FIG. And a part of the disk 4 is inserted into the slits 7,7. The displacement of the disk 4 in the left-right direction in the figure is prevented by the corner portion of the bag 11 and a state in which a part of the disk 4 is inserted into the slits 7, 7. Is prevented by the folded holding portions 6 and 6, so that the disk 4 is held at a predetermined mounting position.
[0031]
When trying to store the disk 4 containing the bag 11 in the disk case having the arc-shaped slits 7 shown in FIG. 1, a part of the bag 11 is easily folded or wrinkled. On the other hand, if the hook-shaped slits 7 are used, the bag 11 can be stored in a state where the bag 11 is almost placed without applying an excessive force, and the storing operation is facilitated.
[0032]
The disk stopper means in the present invention may be constituted by U-shaped slits 7, 7 as shown in FIG. The U-shaped slits 7, 7 are formed such that the opening is directed toward the disk 4, the center is located near the periphery of the disk 4, and both ends extend toward the disk 4. The disk 4 is locked in the state shown in FIG.
[0033]
Further, a claw portion 12 as shown in FIG. 15 may be used as the disk stopper of the present invention. That is, the claw portions 12 are provided on the sides of the holding portions 6 and 6 that are the disk 4 side when the holding portions 6 and 6 are folded back onto the receiving portion 5. By inserting the claw portion 12 below the disk 4 as shown, the displacement of the disk 4 can be locked.
[0034]
In FIGS. 5 to 8, the lower lid 1 and the upper lid 2 which are not shown are the same as those in FIG. 1.
[0035]
Next, another example of the connecting portion between the lower lid portion 1 and the storage portion 3 will be described with reference to FIGS.
[0036]
In the case of the disk case of FIG. 1 described above, the folding line 8b for folding back the storage section 3 onto the lower lid section 1 is formed substantially in line with the end of the lower lid section 1 on the storage section 3 side. On the other hand, in the case of the disc case shown in FIG. 17, the return line 8 b when the storage unit 3 is folded back onto the lower cover 1 slightly penetrates the inside of the lower cover 1. That is, the receiving portion 5 is formed so as to bite slightly inside the lower lid portion 1, and the edge of the receiving portion 5 on the side of the lower lid portion 1 is a folded line 8 b. Other configurations are the same as those of the disk case shown in FIG. 1, and the same reference numerals as those in FIG. 1 indicate the same components.
[0037]
As described with reference to FIGS. 2 and 3, after the disc 4 is placed on the disc case shown in FIG. The state of being turned up (a state corresponding to FIG. 3) is the state of FIG. As is clear from the drawing, a central portion (a connecting portion between the lower lid portion 1 and the storage portion 3) is depressed from the upper and lower portions of the lower lid portion 1 in the drawing. That is, the central portion (the connection portion between the lower lid 1 and the storage unit 3) from the upper and lower portions of the lower lid 1 is recessed by the amount of the folding line 8b biting into the lower lid 1. .
[0038]
The connection state between the lower lid 1 and the storage unit 3 as described above is particularly advantageous when performing wireless binding. That is, in the case of the perfect binding, the back portion of the contents, which have been collated and combined into one book, is cut by milling with a width of about 2.5 to 3 mm, cut into individual pieces, and adhered to the cut portion. In this case, if the connecting portion between the lower lid portion 1 and the storage portion 3 is depressed as described above, the connecting portion is prevented from being separated during milling cut. Can be. Therefore, it is preferable that the biting amount of the folded line 8b into the inside of the lower lid portion 1, in other words, the biting amount of the receiving portion 3 into the inside of the lower lid portion 1, is set to be slightly larger than the width of the milling cut. .
[0039]
Further, another example of the disk case according to the present invention will be described with reference to FIGS.
[0040]
As shown in FIG. 19, the upper lid 2 and the storage 3 are connected to each other with the lower lid 1 as a center, and the upper lid 2 and the storage 3 are provided with an outer window 9a and an inner window 9b. This point is the same as the disk case described with reference to FIG. 1, but the configuration of the storage section 3 is different from the disk case of FIG. This difference will be further described.
[0041]
The entire end side of the storage section 3 on the side of the lower lid 1 is connected to the lower lid 1 and has no gap 10 as shown in FIG. The holding portions 6 and 6 are formed by cutting one other side of the disk 4 constituting the return line 8c and cutting the other three sides. The holding portion 14 is left. The holding portion 14 is folded back onto the receiving portion 5 via the folding line 8d. The slits 7, 7 serving as the disk fixing means are the same as those in FIG. 1, and are replaced with the hook-shaped slits 7, 7, the U-shaped slits 7, 7, and the claw portion 12 described in FIGS. You can also.
[0042]
Next, a procedure for storing the disk 4 in the present disk case will be described with reference to FIGS.
[0043]
The disc 4 is placed at a position as shown in FIG. 19, and the holders 6, 6 are folded back on the receiving part 5 via the folding lines 8c, 8c, and the discs 4 are pressed by the holders 6, 6, and FIG. State. This procedure is the same as the procedure from FIG. 1 to FIG. In FIG. 20, reference numeral 15 denotes a hole formed by folding the holding portions 6 and 6 onto the receiving portion 5.
[0044]
After the holding portions 6 and 6 are folded back onto the receiving portion 5 as described above, as shown in FIG. 21, the holding portion 14 is folded back onto the receiving portion 5 via the folding line 8d, and the holding portion 14 Press 6,6 from above. Thereby, the holding portions 6 and 6 can be hardly separated from the disk 4, and the holding effect of the disk 4 can be enhanced.
[0045]
The procedure after the holding section 14 is folded back onto the receiving section 5 is the same as that of the disk case in FIG. 1, and the entire storage section 3 is folded back onto the lower lid section 1 so as to be in the state shown in FIG. 22, which is not shown. Is further folded back onto the lower lid 1 and then bound to a magazine or book in the same manner as described above. In particular, in the case of the present disk case, since the holding portions 6 and 6 are pressed by the holding portion 14, the holding of the disk 4 by the holding portions 6 and 6 is further ensured. In addition, when the fingers are to be inserted from the side of the bound disc case, the outer frame 13 is present, so that it is difficult to insert the fingers deeply, and the effect of preventing the disc 4 from being removed is improved.
[0046]
The holding portion 14 like the disk case in FIG. 19 can be provided also in the disk case in FIG. That is, the holding portion 14 can be provided as shown in FIG. 23, the same reference numerals as those in FIG. 1 denote the same components as those in FIG.
[0047]
The disk case according to the present invention can store not only one disk 4 as described above but also a plurality of disks 4. For example, as shown in FIG. 24, if two storage sections 3 are connected in parallel to one lower lid section 1, a disk case capable of storing two disks at the same time can be obtained. Further, the disk case shown in FIG. 24 is provided with two storage portions 3 of the disk case shown in FIG. 1, but is provided with two storage portions 3 of the disk case shown in FIG. It is also possible to provide three or more storage sections 3. In FIG. 24, the same reference numerals as those in FIG. 1 indicate the same components as those in FIG.
[0048]
The disk case according to the present invention may have cover pieces 21 and 21 as shown in FIG. The cover pieces 21 and 21 are provided on both sides of the lower cover 1 via the folding lines 8e and 8e, and have outwardly protruding portions 22 and 22 at both ends. As described with reference to FIGS. 2 and 3, the disk case shown in FIG. 25 is provided with the disk 4 placed thereon, the holding portions 6 and 6 folded back onto the receiving portion 5, and the entire storage portion 3 is placed on the lower lid portion 1. 26, the cover pieces 21 and 21 are folded back onto the storage section 3 on the lower cover section 1 and the protruding sections 22 and 22 are inserted below the storage section 3 as shown in FIG. As is apparent from FIG. 26, when the cover pieces 21 and 21 are folded back onto the storage section 3 on the lower cover 1 via the folding lines 8e and 8e, the central portion of the outer edge of the cover piece 21 and 21 is It is caught by the projecting portion of the receiving portion 5 corresponding to the outer peripheral edge portion, and the projecting portions 22 on both ends are inserted below the housing portion 3, so that the housing portion 3 is held therebetween.
[0049]
When the cover pieces 21 and 21 as described above are provided, it becomes impossible to pry a finger or the like between the storage section 3 and the lower cover section 1, so that the effect of preventing the disk 4 from being removed can be improved.
[0050]
As shown in FIGS. 27 and 28, the cover pieces 21 and 21 do not have the protruding portions 22 and 22 (see FIG. 25) and only cover the storage portion 3 folded on the lower cover portion 1. You can also. Even if the cover pieces 21 and 21 are merely covered on the storage section 3 and the cover pieces 21 and 21 are not raised, a finger or the like cannot be pryed between the holding section 3 and the lower cover section 1 unless the cover piece 21 or 21 is raised. 4 can improve the effect of preventing extraction. In particular, when binding to a magazine or book, one end of the cover pieces 21 and 21 is positioned within the binding allowance 20 (see FIGS. 6 and 7), similarly to the holding unit 6 described with reference to FIGS. When this is bound, the cover pieces 21 and 21 are kept in a state of being covered on the holding portion 3, so that the above-described effect of preventing the removal can be further enhanced. At this time, as in the case of the holding unit 6 described with reference to FIGS. 6 and 7, it is easy to open the cover pieces 21 and 21 by providing a separation line.
[0051]
Each of the above examples is convenient for binding to a magazine or book, but the disc case of the present invention can be applied not only for such binding but also as a normal protective case. In this case, it is preferable to provide a lid stopping means for stopping the lower lid 1 and the upper lid 2 which are overlapped with the storage portion 3 interposed therebetween so as not to open. As the lid stopper means, for example, as shown in FIG. 17, a tongue piece 16 provided on the upper lid 2 and an insertion port 17 provided on the lower lid 1 can be used. By inserting the tongue piece 16 into the insertion port 17, it is possible to prevent the lower lid 1 and the upper lid 2 from opening.
