Packaging for a planar data medium

Abstract

A packaging for a planar data medium (2) is described, comprising a base plate (1) having a receiving recess (3) for the data medium (2) and two cover foils (4, 5) covering the receiving recess (3) on both sides of the base plate (1), of which one forms a defined severing line (6) which connects the two ends (7) of a removal opening (8) resulting from tearing open the defined severing line (6) and delimits a hinged cover (10) which can be bent up about a base determined by the two ends (7) of the removal opening (8), with the removal opening (8) extending over a length corresponding to the clearance of the receiving recess (3) as measured in the direction of said boundary area (9). In order to prevent the defined severing line (6) from being torn open inadvertently it is proposed that the removal opening (8) is provided in a boundary region (9) of the receiving recess (3) and that the defined severing line (6) extends into the region of the receiving recess (3) starting from the two ends (7) of the removal opening (8).

Description

FIELD OF THE INVENTION [0001]The invention relates to a packaging for a planar data medium, comprising a base plate having a receiving recess for the data medium and two cover foils covering the receiving recess on both sides of the base plate, of which one forms a defined severing line which connects the two ends of a removal opening resulting from tearing the defined severing line and delimits a hinged cover which can be bent up about a base determined by the two ends of the removal opening, with the removal opening extending over a length corresponding to the clearance of the receiving recess as measured in the direction of said boundary area.DESCRIPTION OF THE PRIOR ART [0002]In order to mail planar electronic data media, especially disk-like data media, it is known to provide packaging in the form of postcards which consist of a rectangular base plate with a receiving recess adjusted to the contour of the data medium and of two cover foils covering said receiving recess on both...

Benefits of technology

[0005]As a result of these measured, a substantial part of the defined severing line extends in the area of the data medium received by the base plate which absorbs a portion of the bending load and represents a stiffening of the packaging especially in the area of the course of the defined severing line, so that the bending loads acting upon the covering foil with the defined severing line are limited to an amount which excludes the defined severing line from being torn open. A simple removal of the data medium from the packaging is nevertheless ensured because the defined severing line delimits a hinged cover which, once the defined severing line has been torn open, can be bent up about a base defined by the ends of the removal opening, so that after bending up the hinged cover the data medium can now be removed via the now opened removal opening of the packaging transversally to the boundary region of the receiving recess associated with the removal opening. The data medium can obviously also be stored in the opened packaging. After the insertion of the data medium in the receiving recess it is obviously possible to close the hinged cover again.

[0006]Especially advantageous constructional conditions are obtained when the defined severing line has a progression which is symmetrical with respect to a central normal line on the area of the receiving recess with the removal opening, because in this case the branches of the defined severing line which are symmetrical with respect to each other are supported in a corresponding manner by the data medium and consequently both branches are protected in the same manner from inadvertent opening. This requirement is met especially by a hinged cover with a triangular basic form which in addition ensures simple handling. The corner region of the hinged cover which is obtained as a result of the triangular shape allows a simple attack of the hinged cover in the middle in order to tear open the severing line starting from said corner region towards the two ends.

[0007]When the hinged cover extends up to the central area of the receiving recess, the defined severing line can be supported via the data medium in an advantageous manner without impairing the support in the opened packaging.

[0008]In order to increase security against inadvertently tearing open the defined severing line, the base plate may comprise sections which reduce the bending stiffness of the base plate on at least one side of the receiving recess. As a result of reduced bending stiffness of the base plate as a result of these sections, it is not possible to transmit higher tensions from the base plate to the foil section with the defined severing line, so that forces caused by this transversally to the defined severing line are avoided. These base plate sections which reduce the bending stiffness can be ensured by choosing different materials in various sections. Especially simple constructional conditions are obtained when said flexible sections are achieved by recesses in the base plate. It is in no way mandatory to arrange these recesses as breakthroughs in the base plate. In the case of a layered arrangement of the base plate it would be possible to omit at least one layer in the area of the recesses for example.

Problems solved by technology

When this removal opening is formed by a slit in one of the cover foils (DE 20108193 U1), then this leads to the disadvantage that the data medium can be removed in an unauthorized way.

The defined severing lines extending substantially along a boundary region of the receiving recess come with the disadvantage however that in the case of a bending load on the packaging there is a likelihood that the defined severing line is opened inadvertently at least in sections.

Since such bending loads on the packaging are unavoidable during conveyance between conveying rollers as are used in automatic mail sorting systems, such known packaging does not meet postal requirements.
