Interactive postcard and process of manufacturing
The invention concerns a packaging means for multimedia storage means, particularly compact disk (CD) , CD read only memory (CD-ROM) , and digital versatile disk (DVD) . It is especially adapted for mails and mailing, and will be called Interactive postcard. The invention concerns also the process of manufacturing of the Interactive postcard.
There are many types of packaging means for holding CDs, the most known being a hinged box of polystyrene called jewel box. The first drawback of such solution is that it is thick and fragile and can not easily be sent by postmail, but requires the use of a specific expensive protective enveloppe . A second drawback is that a separate letter must be used when a written information needs to be joined to the mail of the CD.
A first object of the present invention is to provide a packaging means for multimedia storage means, particularly adapted for an economic and safe mail, and its manufacturing process .
A second object of the present invention is to provide a packaging means for multimedia storage means, also adapted for use of non multimedia data like printed information and handwritten information.
These objects will be apparent from the following description of specific embodiments, based on the following figures :

Figures la to If represents the manufacturing process of a first embodiment of the present invention.
In a first phase (fig la) , the front side If of a cardboard 1, GC - FBB folding box board, is printed. A top part It of the carboard countains a print representing the postcard model including for instance stamp and address positioning, and a bottom part lb of the cardboard contains a printed image illustrating a thema, for example a new year thema . This cardboard is about 370 gramms/m2 type. In a second phase (fig lb) , an adhesive means 2 is applied on the whole rear side lr of the cardboard 1. This adhesive means is preferably a varnish for bakercard.
In a third phase (fig lc) , a recessed portion 3, having the size and shape of the multimedia storage means to store, is performed by embossing the top part on the rear side of the cardboard. Its edge represents an enclosure for the multimedia storage means. A perforation is performed on the bottom part of the rear side cardboard in order to make both dotted lines 4 and a hole 5, which have a function of easy aperture means. In fact, the hole 5 has the technical function to allow a person to put a finger in order to open a window in the card along the dotted lines 4, as illustrated in figure lg.
In a fourth phase (fig Id) , the multimedia storage means 6, which is a rectangular shaped CD in this embodiment, is put in the recessed portion of the top part on the rear side of the cardboard. The multimedia content of the CD represents additional information on the same thema as the printed information.
In a fifth phase (fig le) , the cardboard is folded along the folding line 7 in order to put in contact the two top and bottom rear parts, while maintaining the CD in the right place.
In a sixth phase (fig If) , the resulting packaging means is heated and pressed with a means 8 presenting a recessed portion 9 corresponding to the position of the CD. This leads to the bonding of the two parts of the cardboard thanks to the adhesive means. An important feature is that no bonding action is performed above the CD, but only around. Other alternative bonding means could be used.
As a result, a postcard type packaging is formed with about the same size and thickness of a classical postcard, containing safely a CD. Its aperture is easy, because it consists in manually pulling the card through the central hole 5. The result is an opening of two panels like a French window aperture (Fig lg) , around the CD, allowing to take it easily.
As an optional advantageous feature, the CD can have a thiner portion on its extremity circumference part, adapted to be put on an adhesive area of the cardboard around the recessed portion while the thicker CD portion being placed in the recessed portion. This feature helps to maintain the CD in the right place.
Figure 2 represents the manufacturing process of a second embodiment of the present invention.
The first and second phases (fig 2a and 2b) are the same as phases represented on fig la and lb of the first embodiment .
In the third phase (fig 2c) , a hole 13 is made in the top part of the cardboard, having about the size and shape of the multimedia storage means to store. This embodiment is adapted to a round shape DVD, with standard diameter of 8 centimeters. A perforation consisting in dotted lines 14 is performed on the bottom part of the cardboard. This perforation represents about half of the hole 13 circumference, and contains a tab 1-5.
In parallel to the previous phases, a transparent holding element 17 is made by thermoforming a plastic material like polyethylene. This holding element (represented in fig 2d) has a round shape corresponding to the DVD size, comprises a recessed portion 18 with a central protuberant cross shaped retaining means 19 with a thickeness of about 1.5 mm, which function is to engage the central hole of the DVD in order to retain it and to avoid its rotation, an edge 20 of about 1.5 mm thickness which corresponds to a little more than the DVD thickness of 0.8' mm and represents an enclosure for the DVD and a ring 21 destinated to be placed on the cardboard around the hole 13, the recessed portion being put in the hole 13. Moreover, the ring 21 contains a first larger area 22 whose technical fonction is to help the right positionning of the holding element on the cardboard, this larger area extremity being placed parallel and along the folding line 7 between the top and the bottom parts of the cardboard. It contains also a tab 23 whose technical fonction is to help the future aperture of the card, which is described below.
In the fourth phase (fig 2d) , the holding element is put in the hole 13 of the top part of the cardboard, in such a manner that the specific ring portion 22 being along the folding line 7.
In the fifth phase (fig 2e) , the DVD 16 is placed in the recessed portion of the holding element 17. In parallel to this process, the DVD content has been stored on the DVD, consisting in complementary information on the same topic as the printed data on the cardboard. Also, the
front surface of the DVD is printed and the right positioning of the DVD in the transparent holding element 17 allows to form a front side of the Interactive Postcard having a continuous printed pattern, both on the cardboard and on the DVD. For the easy and quick right positioning of the DVD, a high number of DVDs are first automatically positioned on a rod with the same orientation. Then, the right positionning of the rod in the process allows to automatically position all the DVDs it contains. For the automatic right positioning of the DVDs, a printed black mark is made on the surface of the DVD as well as a corresponding mark on the holding element such that a machine with an optical sensor is able to orient the DVD by superposing both marks for example.
The next two phases (fig 2f and 2g) correspond to respectively the phases of fig le and If of first embodiment. Once folded, the tab 15 of the dotted line is superposed to the tab 23 of the holding element.
As a result, a postcard type packaging is formed, containing a DVD, with about the same size and thickness of a classical postcard. It is adapted for standard DVD with a thickness comprised between 0.8 and 1.2 mm, the thickness of the holding element being respectively comprised between 1.5 and 2 mm. Its aperture is easy, because it consists in manually pushing with the thumb the front side of the interactive postcard, on the area corresponding to the tab 23, while maintaining the rear
side with the other hand. This provides a folding effect of the whole interactive postcard and a resulting pressure force on the tab 23 which transmits the pressure force to the dotted lines tab 15 thanks to its rigidity propriety, leading to the opening of the rear side cardboard along the doted lines. The DVD can then be taken out .
As an alternative solution for this embodiment, a rectangular shaped DVD can be used. The holding element and the perforation are then adapted as illustrated in figure 2h. The tab 23 and the larger ring 22 are then met in only one element, and the dotted lines follow half the holding element circumference.
As a further alternative solution for this embodiment, an airtight means, like an aluminium fold placed above the holding element and between the two superposed carboard parts, is used in order to close the holding element. This aluminium fold is bonded to the two cardboard parts. This allows to insert within the recessed portion a perfume substance, which will only liberate its flagrance at the opening of the Interactive postcard.
Figure 3 represents a third embodiment of the present invention in an unfolded state. It differs from the previous ones in that during the third phase of the manufacturing process, both a cut out of a part of the bottom part and a perforation are made. The result is an
open window 30 in the bottom part corresponding to about half the surface of the holding element 17, symmetric around the tab 33, and hinged along a folded line 31. The dotted lines follow the border of this window. It defines an extremity band 32 which contains on its internal face an adhesive means 33, protected by a removable protection.
This product is like a self made postcard : it allows a user to insert a CD-R in the holding means, to glue the window 30 to the top part of the cardboard by removing the protection for releasing the adhesive means 33. The band 32 is then bonded to the ring 21 and/or the top rear part of the cardboard. Then, a person can easily transport and mail the closed product . The aperture can be performed along the dotted lines, using the method described in the previous embodiment .
A fourth embodiment is represented in figure 4. The final interactive card comprises a two hinged parts, the left part being a card as described previously, linked to a further panel part of usual cardboard, in order to represent a double interactive mail card, especially adapted for greeting cards use.
A fifth embodiment is represented in figure 5. It consists in a three parts card, hinged around the two lines 50 and 51, comprising a first panel 52 corresponding to a multimedia packaging as previously described, a second panel 53 of cardboard only of the
same size, and a middle small part 54 whose width corresponds to the thickness of a book to insert between the two panels 52 and 53. This allows to propose more written information, a richer content, still both multimedia and classical. This embodiment can be used for tourist guides.
An alternative of this last embodiment consists in an easy removal means like dotted lines between the first panel 52 and the middle panel 54 , in order to use it separately as postcard for example.
Of course, a combination of the above described embodiments would be possible for the man skilled in the art. For example, any embodiment can be made with any multimedia storage means, from any shape, round or rectangular, or any other like heart-shaped. Although, any easy aperture means could be adapted with any above embodiments .
Finally, the interactive postcard of the invention presents the following advantages :
-the packaging means is thin, compact, compatible with existing standards of multimedia storage means. Even if particularly adapted for CDs, DVDs, it can be used for floppy disks, smart cards, any thin storage means ;
-the packaging means including the multimedia storage means has about a postcard format, comprises the postcard function, is adapted for a mail use on the same way as classical postcards, without any additional envelope ;
-it allows to transfer an information through the use of at least three complementary supports, the carboard print, its written part and the digital content of the multimedia storage means ;
-it is safe since the multimedia storage means is protected and the aperture of the packaging means is easily detected ;
-it is cheap and easy to manufacture.
