Description

The protecting box of optical disk structure

The utility model relates to the protecting box of optical disk structure that can freely lay and adorn long-playing record CDs such as (CD) with taking out.

With music long-playing record (CD) and CD-ROM such as personal computer software, game software is the CD (recording medium) of representative, normally is placed in the protecting box of optical disk, takes care of, carries or carry, displays.

Referring to Fig. 4 as can be seen, this box (protecting box of optical disk) 118 has by hinge 112 and connects, bottom (bottom) 114 that can freely openable and cover (enclosing cover) 116.Here, box 118 is to have and its bottom 114 all-in-one-pieces, fix by inserting among the center pit 120a, can keep bonding part 122 CD 120, that be roughly cylindrical shape to be provided with on this bottom 114 by embedding installs, be contained in the form of the other pallet of inner face regularly, as shown in Figure 4.This box can be used as and is used for adorning at the most a music CD, or the box of the simple type of the CD of low-priced edition (CD-ROM) etc.

Yet in well-known simple and easy flask 118 shown in Figure 4, the hinged end edge of the base portion 116a of its lid 116 is made the cross section and is roughly the コ font, and this hinged end has the wall 152 of turning back.When closing this box, this wall 152 can lean against on the base portion 114a of above-mentioned bottom 114.Along with the insertion of the insertion front end of the part that is roughly the コ font to this, for example, the sleeve for phonograph record 124 of inbuilt card-shape can be contained on the inside surface of base portion of this lid.In addition, by with card-shape, the front end 124a bending of inbuilt sleeve for phonograph record or turn back, the rear wall 138 that this can be roughly コ font part is as uses such as title display surfaces.

But, form and cover 116 the part that is roughly the コ font and be not easy, and, because this part that is roughly the コ font is arranged, to prolong the cool time when making this box etc., therefore, unavoidably can make the forming operation complexity of box, and curring time postpones.

In addition,, cover the mould structure complexity of 116 shaping usefulness, under well-known situation, the cost of shaping is improved owing to will form the part that this is roughly the コ font.

In addition, in well-known structure, on the base portion 114a of above-mentioned bottom, form and this wall of turning back 152 corresponding breach 154 with the part that is roughly the コ font.But owing to done this breach 154 on the base portion 114a of this bottom, the hinge fraction of this bottom 114 can only be made the pair of sidewalls 130 that direction is relatively extended, and therefore, the intensity of this bottom hinge part is reduced.

Moreover because the scope of breach 154 on the base portion of this bottom is than broad, when opening and closing this box 118, the user can worry to clip it and point etc.This clip finger phenomenon though the safety problem that has nothing special opens and closes owing to hinder sleekly, therefore, from using consideration, can not be said fine.

The purpose of this utility model is to provide a kind of shaping easy, and the good protecting box of optical disk structure of usability.

In order to reach this purpose, the effect of the wall of turning back on the hinged end edge of the base portion of lid is studied again, found that in the protection box of simple type, this wall of turning back does not have the effect of what particular importance.Therefore, according to this structure,, the shape that rear wall erects, the cross section is roughly the L font is made at the hinged end edge of the base portion of this lid according to the utility model.Like this, when bottom and lid are closed, can make this rear wall top aim at and engage with the inside surface at the hinged end edge of the base portion of bottom.

Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.

As Fig. 1 (A), Fig. 1 (B) and shown in Figure 2, in protecting box of optical disk structure 10 of the present utility model, protecting box of optical disk 18 is by opening and closing the bottom 114 of connection freely and constituting of lid 16 with hinge 12.In addition, as can be seen from Figure 2, the structure of protecting box of optical disk 18, can freely pack into take out and protection as the CD of recording medium, for example, the CD-ROM of music long-playing record (CD) and personal computer software, game software etc. etc.This box has on 14 by inserting among the center pit 20a and with this hole in its bottom and engages, can keep CD 20, profile is roughly columnar bonding part 22; And have joint fastener 26 on the base portion 16a inside surface that joints such as the built-in type sleeve for phonograph record 24 of card-like and built-in type instructions 25 can be remained on lid on 16 at lid.

This box (protecting box of optical disk) 18 roughly has following form.

As shown in Figure 2, bottom 14 is that on end antetheca 28 as on the switching end margin of the base portion 14a with bonding part 22; And in its both sides, on end the form of sidewall 30 forms; And, on the both sides of the edge of the hinge fraction of this base portion, on end as the joint pin of hinge 12 and the hinge plate 32 that highlights.

Corresponding, on two lateral edges of lid 16 base portion 16a, the relative sidewall 34 of on end a pair of direction respectively; And in two places of this each sidewall, promptly four places altogether are provided with outstanding joint fastener 26.The card-like built-in type sleeve for phonograph record 24 that inserts from the switching end as this box of the openend that does not have wall and built-in type instructions 25 etc. can be fixed and keep to these joint fasteners 26.In addition, the hinge fraction of the sidewall 34 of lid 16 is made for example certain narrow step shape of width, this hinge fraction by with the recess of the sidewall outer of narrow width part 36, utilize joint pin to carry out gapped cooperation, can be connected with lid, freely open and close with bottom 14.

The basic structure of this box 18 is well-known, because this basic structure itself is not the problem that the utility model will be discussed, therefore, omits its detailed description.

Except Fig. 2, can find out also that from Fig. 1 (A), Fig. 1 (B) in the utility model, the hinged end edge of the base portion 16a of lid makes that rear wall is 38 that erect, the cross section is roughly L shaped shape.When lid 16 and bottom 14 when closing, this rear wall top 38a can aim at and engage with the inside surface at the hinged end edge of bottom base 14a.

That is to say that in the utility model, the hinged end edge of the base portion 16a of lid is roughly the コ word shape from well-known cross section, becomes the shape of having removed the wall of turning back.Therefore, the shaping of lid 16 is easy, and particularly, owing to can shorten cool time, the stroke of shaping also can shorten.

In addition, if adopt the shape of the lid of the present utility model of the part that is not roughly the コ font,, therefore, can reduce greatly and cover 16, and then be the cost of box 18 because the mould of shaping usefulness is simple.

Because rear wall top 38a can aim at and engage with the hinged end edge inside surface of the base portion 14a of bottom, so when improving this hinged end edge strength greatly, can prevent intrusions such as dust effectively again.

In addition, according to the utility model, because on the hinged end edge of bottom base 14a, be provided with the breach of wide ranges, and the hinged end edge of bottom base may extend to the position of aiming at the rear wall top 38a of this lid, therefore, can prevent problems such as clip finger when lid opens and closes reliably.Like this, open-close lid 16 sleekly, and then open and close box 18 sleekly, therefore, can improve the usability of this box reliably.

Moreover, because hinge plate 32 is not independent from bottom base 14a in roomy scope; And be used to obtain flexible otch 40 and be located at bottom base, therefore, the intensity at the hinge fraction place of this bottom 14 can strengthen (referring to Fig. 3) reliably.

In addition, because being shaped as of lid 16 of the present utility model on the hinged end edge, do not have the cross section to be roughly the part of コ font, therefore, hinged end edge can not be fixed and remain on to the built-in type sleeve for phonograph record 24 of card-like.But,, can fix and keep the built-in type sleeve for phonograph record 24 of this card-like owing to the joint fastener 26 of sidewall, therefore, though be in of the present utility model, on the hinged end edge, be not roughly the form of コ font part, can prevent reliably that the built-in type sleeve for phonograph record of this card-like from coming off yet.

And for example shown in the figure,, and insert,, can easily utilize the rear wall 38 at the hinged end edge of lid, as the title display surface then with existing the same if with the front end 24a warpage of the built-in type sleeve for phonograph record 24 of this card-like.

That is to say,, can easily reach and neither damage function, can improve the usability of box 18 again according to the utility model.

And for example Fig. 2, shown in Figure 3 preferably makes the rear wall 38 of this lid become one continuously with pair of sidewalls 34.Adopt this structure,, therefore, improve easily and cover the rigidity of 16 (and then being box 18) because the intensity of rear wall 38 and sidewall 34 increases.In addition, by improving the rigidity of box 18, can improve the function of the box of protection CD 20 more.

In addition, in this box 18, make the part 36 of narrow width, and the hinge plate 32 of bottom is configured on the part of this narrow width, can remove from the outstanding part of the periphery of box by the hinge fraction that will cover 16 sidewall 34.In addition, in the utility model, as shown in Figure 3, by the part 36 that forms this narrow width, width between a pair of step difference end 36a that the inboard towards sidewall 34 can be highlighted, be set at the interior dress sleeve for phonograph record 24 that can guarantee card-like and insert, and the size that can engage with the insertion front end corner part 25a of interior dress instructions 25.

According to this structure, because the interior dress sleeve for phonograph record 24 of card-like, the insertion of the abutting end of dress instructions 25 etc. in can being configured to not hinder, simultaneously, interior dress instructions can suitably be located at its allocation position, therefore, can not make the operation of the interior dress sleeve for phonograph record of laying card-like together and interior dress instructions and configuration become complicated.

In addition, saving the interior dress sleeve for phonograph record 24 of card-like, and under the situation with dress sleeve for phonograph record in the front cover double as of interior dress instructions 25, shown in the dotted line among Fig. 2 and Fig. 3, also can be on the inside surface of the base portion 16a of above-mentioned lid, the copulational protuberance part 42 that setting can engage with the insertion front end of interior dress instructions.When adopting this structure, because advancing of the insertion front end of interior dress instructions 25 is not to only depend on its corner part 25a, but be prevented from by the joint of integral part; Therefore, can prevent more reliably that interior dress instructions from piercing to the hinged end edge direction too much.

Like this, the location of interior dress instructions 25 is more prone to and is reliable.

The foregoing description just for the utility model is described, is not to restriction of the present utility model.Change of being carried out in technical scope of the present utility model and transformation etc. are included in the utility model all.

As mentioned above, according to the structure of protecting box of optical disk of the present utility model, because lid is made on its hinged end edge; do not have the cross section to be roughly the shape of コ font part, therefore, the shaping of this lid is easy; particularly owing to can shorten cool time, the stroke of shaping can shorten.Because this lid is the shape that is not roughly コ font part, make the mould of shaping usefulness simple again, therefore, can reduce the cost of lid and box greatly.

Owing to can make the rear wall front end aim at and engage, therefore, when improving the hinged end edge strength greatly, can prevent intrusions such as dust effectively again with the hinged end edge of bottom base.

Moreover, owing on the hinged end edge of bottom base, do not make the very wide breach of scope, and the hinged end edge of this bottom base can extend to the position of aiming at the rear wall of this lid, therefore, the problems such as clip finger in the time of can preventing this lid switching reliably.Like this, can open and close this lid sleekly, and then can open and close this box sleekly, thereby can improve the usability of this box reliably.

In addition, independent on a large scale because hinge plate is not the base portion from this bottom, in order to obtain flexible otch, be located on this bottom base, therefore, can improve the intensity of the hinged end edge of this bottom reliably.

In addition, because the rear wall of this lid is become one with pair of sidewalls continuously, the intensity of rear wall and sidewall is increased, the rigidity of lid improves, and therefore, more can strengthen the function of box protection CD.

Moreover, by will be, make the interior dress sleeve for phonograph record that both can guarantee card-like and insert, and can engage with the corner part of the insertion front end of interior dress instructions to the width between a pair of step difference end that inside sidewalls highlights, therefore, the interior dress sleeve for phonograph record of card-like inserts and configuration easily; Simultaneously and since interior dress instructions can be on its allocation position suitable location, therefore, can not make the operation and the configuration of the interior dress sleeve for phonograph record of laying card-like together and interior dress instructions complicated.
