Abstract

The invention relates to a format adapter comprising a storage device having: a front surface provided with electrical contact pads opposite a rear surface defining a lower peripheral border (2a); a body having a cavity (4) for receiving the device and opening on a front and rear side of the body, and; an adhesive film (8a), which is sensitive to pressure, adhered to the rear side of the body and which has at least one adhesive portion inside the cavity in order to hold the storage device. The adhesive film has an inner recess (10) essentially centered on the cavity and has at least one shoulder bordering on the cavity that assures a localized adhesion only on the lower peripheral border (2a) of the storage device. The invention also relates to a method for producing the adapter and to a use of the adapter for manufacturing and packaging the storage device.

Claims

1. Format adapter comprising a storage device having a front surface equipped with electric contact pads opposite a rear surface defining a bottom peripheral border, said adapter comprising a cavity for accommodating the device which opens onto the front and rear surfaces of the body, and a pressure-sensitive adhesive film, glued to the rear surface of the body and having at least one adhesive portion inside the cavity in order to hold the storage device,

wherein the adhesive film has an inner recess substantially centred on the cavity and at least one shoulder bordering on the cavity assuring localised adhesion only on the bottom peripheral border of the device.

2. Adapter according to claim 1, wherein the shoulder is continuous.

3. Adapter according to claim 1, wherein the shoulder has a width comprised between 0.1 and 5 mm.

4. Adapter according to claim 1, wherein the recess is sized such as to allow the device to be pressed directly with a finger through the recess.

5. Adapter according to claim 1, wherein the film extends perfectly out to the outer edge of the adapter body.

6. Adapter according to claim 1, wherein said adapter is connected in a detachable manner to an attachment support body with a larger surface by a partial pre-cut.

7. Adapter according to claim 6, wherein the attachment body comprises a detachable device intended for the cavity.

8. Adapter according to claim 6, wherein the format of the attachment body corresponds to the ISO format.

9. Adapter according to claim 1, wherein the film has an adhesive strength that can withstand a pressing force on the mini-card of less than 8 N while providing resistance to delamination of more than 3 N/cm between the film and the adapter.

10. Adapter according to claim 1, wherein the external format of the adapter body is the same as the Plug-in UICC format and the cavity is sized to accommodate a Mini-UICC card.

11. Adapter according to claim 1, wherein the format of the adapter body is the same as the ISO format and the format of its cavity matches that of a Mini-UICC or Plug-in UICC card or any of the various storage-device formats such as SD, MMC, Mini SD, MMC Micro or Memory Stick or USB key or any memory-card format with accessible contacts on the top surface.

18. Use of the adapter according to claim 1 to a adapt a chip-card production operation to a storage-device production operation with a format that is different from a chip card, such as SD, MMC, Mini SD, MMC Micro, Memory Stick or USB key format.

19. Use according to claim 18, wherein the storage-device production operation comprises an operation chosen from insertion, electric and/or graphical customisation.

20. Use of the adapter according to claim 1 as packaging for the device.

12. Method of producing a format adapter for a storage device, said method comprising the following steps according to which:

a support with a cavity for accommodating the device opening onto the front and rear surface of the body and an area for extraction of the adapter body is provided,

a pressure-sensitive adhesive film is fixed to the rear surface of the support, at least partially covering the cavity, and

the adhesive film is sized and positioned so as to have an inner recess substantially centred on the cavity and at least one shoulder located only at the inner peripheral margin of the cavity.

13. Method according to claim 12, wherein the recess is formed by cutting, the film being fixed on the support.

14. Method according to claim 12, wherein

the support is provided with an area for extracting the body of the adapter,

the film is applied such as to cover at least the entire extraction area of the adapter,

a partial pre-cut of the adapter is made along a delimitation of its extraction area so as to cut the excess adhesive film beyond the surface of the adapter and to form a pre-determined breakage line ensuring that the adapter can be detached from the support.

15. Method according to claim 12, wherein the support also comprises an area for extracting a mini-card compatible with the adapter.

16. Method according to claim 15, wherein the mini-card is pre-cut so as to form a predetermined breakage line ensuring that the mini-card can be detached from the support.

17. Method according to claim 12, wherein the support is in ISO format.
