However, the conventional C
In the D storage case, since the entire surface of the holding tab 27 facing the substrate 21 is a plane parallel to the substrate 21, especially when the booklet 26 is thick, when the booklet 26 is incorporated into the lid 3, FIG. As shown in FIG. 7, there is a problem that the booklet 26 is easily caught on the side surface of the holding tab 27. This impairs the usability for the user, and also lowers the efficiency of the assembling work at the time of manufacturing, which hinders the automation of the assembling work.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a CD storage case in which a booklet can be incorporated into a lid without any trouble.

[0009]

According to a first aspect of the present invention, in order to achieve the above object, a bottom and a lid are rotatably opened and closed by a support shaft at one side edge thereof. In a CD storage case for storing a CD, the lid includes a substrate portion positioned in parallel with the CD, side wall portions bent from both side edges of the substrate portion to face each other, and the substrate portion protruding from an inner surface of the side wall portion. And a holding tab for holding the booklet between the support tab and a supporting portion of the holding tab facing the substrate portion. A guide inclined surface which is inclined toward the axis side in a direction in which a gap between the substrate and the substrate portion is reduced is formed.

When the booklet is incorporated in the lid, the booklet is inserted between the side walls from the side opposite to the support shaft along the substrate. Finally, the booklet is held by its both sides being located between the substrate part and the holding tabs on both side walls. At this time, the leading end of the booklet is smoothly introduced between the substrate and the holding tab by the guide inclined surface of the holding tab on the substrate facing surface, and the leading end of the booklet is caught on the side surface of the holding tab. Or not.

According to a second aspect of the present invention, there is provided the CD of the first aspect.
In the storage case, the guide inclined surface is formed only in a substantially half range on the opposite side to the support shaft in the substrate portion facing surface, and the remaining portion of the substrate portion facing surface is formed as a parallel surface parallel to the substrate portion. In addition, the thickness of the holding tab at the end edge opposite to the support shaft is set to about half the thickness of the holding tab in the parallel plane.

Here, the formation of the guide inclined surface in substantially half the area of the holding tab facing the substrate portion means that the inclination of the guide inclined surface is made gentle enough to guide the booklet smoothly, The distance between the substrate portion facing surface and the substrate portion at the end edge opposite to the support shaft can be made sufficiently large. However, if the thickness of the edge portion of the holding tab is too small, the strength of the holding tab may be reduced and a user may be injured. Preferably, the thickness of the tab is limited to about half the thickness of the retaining tab in the parallel plane. Also, the fact that the remaining half of the area of the substrate facing surface of the holding tab is a parallel plane prevents the corner of the holding tab from becoming an acute angle and makes the holding of the booklet more stable. I do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a CD storage case according to the present invention will be described below with reference to FIGS. Note that the same reference numerals are given to portions common to the CD storage case shown in FIGS. 4 to 6 described above, and description thereof will be omitted. In this embodiment, two or three (this figure shows the former) protrudingly formed on the inner surfaces of both side wall portions 22 of the lid 3, all of the holding tabs 27 each having a substantially semicircular planar shape are provided with a substrate. In the direction in which the gap between the substrate portion 21 and the substrate portion 21 is reduced from the edge of the distal end wall portion 30 side of the substrate portion opposing surface 41 toward the base end wall portion 29 on the substrate portion facing surface 41 facing the portion 21. An inclined guide inclined surface 41a is formed. The guide inclined surface 41a is formed on the front wall portion 30 on the substrate portion facing surface 41.
It is formed only in a substantially half area on the side, and the remaining almost half area of the substrate facing surface 41 is a parallel surface 41b which is continuous with the guide inclined surface 41a and parallel to the substrate 21. On the other hand, the surface of the holding tab 27 opposite to the substrate 21 is a plane parallel to the substrate 21. The side surface of the holding tab 27 has a direction perpendicular to the substrate 21. Further, the thickness t1 of the holding tab 27 at the end edge on the side of the base end wall portion 29 is set.
Is about half (t2 / 2) of the thickness t2 of the holding tab 27 on the parallel surface 41b.

Then, in order to incorporate the booklet 26 into the lid 3, the booklet 26 is inserted along the inner surface of the substrate portion 21 of the lid 3 from the end wall 30 side to between the side wall portions 22. Finally, the booklet 26 is held by its two side portions being located between the substrate portion 21 and the holding tabs 27 of the both side wall portions 22, and the base end wall portion 29 and the booklet holding ridge 31 are formed. Between them to prevent displacement. It should be noted that the user of the CD 1 inserts and removes the booklet 26 manually, but it is common for the incorporation of the booklet 26 to the lid 3 to be automatically performed by an incorporation device during manufacturing.

When assembling such a booklet 26,
As shown in FIG. 2, the leading end of the booklet 26 is smoothly introduced between the substrate portion 21 and the holding tab 27 by the guide inclined surface 41 a on the substrate portion facing surface 41 of each holding tab 27. Even if the 26 is thick, the front end of the booklet 26 does not catch on the side surface of the holding tab 27. Therefore, the booklet
26 can be installed smoothly without any trouble, the usability is improved for the user, and the automatic installation by the installation device can be performed without any problem.

Further, since the guide inclined surface 41a is formed in substantially half the area of the substrate portion opposing surface 41 of the holding tab 27, the inclination of the guide inclined surface 41a is gently reduced to the extent that the booklet 26 can be smoothly guided. On the other hand, the distance between the substrate portion opposing surface 41 and the substrate portion 21 at the edge on the side of the distal end wall portion 30 can be made sufficiently large. That is, unlike the case where the corner of the holding tab is simply chamfered, the incorporated booklet 26 can be reliably and smoothly guided.

On the other hand, if the thickness of the edge of the holding tab 27 is too small, the strength of the holding tab 27 may be reduced, and the user may be injured. The thickness t1 of the holding tab 27 at the edge on the base wall portion 29 side
Is approximately half of the thickness t2 of the holding tab 27 on the parallel surface 41b, so that the guide of the booklet 26 can be surely guided without causing problems such as damage due to reduced strength of the holding tab 27 and injury to the user. And can be.

Furthermore, since substantially the remaining half of the area of the substrate-facing surface 41 of the holding tab 27 is the parallel surface 41b, the corner of the holding tab 27 on the base-end wall 29 side of the substrate-facing surface 41 is formed. The section does not have an acute angle, and there is no risk of injury to the user, and the booklet 26 can be held more stably. In addition, the existence of the parallel surface 41b indicates that the lid 3 made of synthetic resin is used.
There is also an advantage in that the molds can be easily combined in molding.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made. For example,
In the CD storage case of the above embodiment, both side walls of the lid 3
Although two holding tabs 27 are provided on each of the 22, the number of the holding tabs is not limited thereto. For example, there are three holding tabs on each side wall of the lid. Is also good. Further, in the above-described embodiment, the planar shape of the holding tab 27 is substantially semicircular, but the planar shape of the retaining tab may be rectangular or the like, and can be an appropriate shape. In the case where the planar shape of the holding tab is rectangular, the edge of the holding tab opposite to the substrate portion on the side opposite to the support shaft should be formed in an arc-shaped cross section when molding the lid with synthetic resin. This can be easily performed, whereby the booklet to be incorporated can be more reliably prevented from being caught. Furthermore, the stored CDs are audio CDs, CD-ROMs
Various things are possible.

[0020]

According to the first aspect of the present invention, in the CD storage case in which the bottom and the lid are connected to each other by the support shaft, the substrate portion is provided on the surface of the holding tab for holding the booklet in the lid facing the substrate portion. Since the guide inclined surface inclined in the direction in which the gap between the lid and the substrate portion becomes smaller from the end edge of the opposite surface to the support shaft and the support shaft side toward the support shaft side is formed, when the booklet is incorporated in the lid, Does not catch on the side surface of the holding tab, and the booklet can be smoothly incorporated without any trouble.

According to the second aspect of the present invention, in addition to the effect of the first aspect of the present invention, the guide inclined surface is formed only in a substantially half range on the opposite side to the support shaft on the substrate portion facing surface, and Since the remaining portion of the opposing surface was a parallel surface parallel to the substrate portion, and the thickness of the holding tab at the edge opposite to the support shaft was about half the thickness of the holding tab at the parallel surface, The booklet to be incorporated can be smoothly guided without causing a decrease in the strength of the holding tab, without forming an acute portion at the corner of the holding tab, and without impairing the stability of holding the booklet.
