DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a package for storing and displaying a plurality of box-shaped articles, more particularly data carriers such as floppy disks and the like, which package comprises receiving means in the form of a plurality of sheaths, one for each box-shaped article, each sheath being provided with: of the insertion opening, insertion opening and recedes relatively to the first longitudinal side, and wall part, of the back face part, from the first longitudinal side in the direction of a second, opposite longitudinal side of the back face part, sheath.


DESCRIPTION OF THE PRIOR ART

Such a package is disclosed in DE-A-36 22 140. In the store position, the sheaths with the articles stored therein are positioned one directly above the other, which yields a compact, block-shaped package. In the display position, the various sheaths are shifted relatively to each other so as to overlap like roof tiles, so that, as a result of the second receding edge of the insertion opening, a surface-shaped part of each article is visible. This surface-shaped part may contain information about the article and the contents thereof, so that a specific article can be selected and taken out of the package without affecting the other articles in their stored positions.
In both the extreme display position and the store position, the various sheaths must be arrested relatively to each other. In the display position, this is effected by the transition between the back face part and the coupling part striking the receding edge of the top wall part, which edge forms the second edge of the insertion opening. Movement to the store position is limited in that a first lip, hinged on both sides of the back wall part and extending downwards, folded back under the top wall part of a subjacent sheath, strikes a second lip, hinged on both sides of that back wall part and extending downwards, folded back under the back face part of that subjacent sheath. To permit the superjacent sheath to move relatively to the subjacent sheath from the store position to the display position, an open slot should be present in the sides of the subjacent sheath, having a length equal to the sum of the desired moving distance and the height of the firs lip. This means that the sides of those sheaths are of open design through the greater part of their lengths, so that the protection provided to the stored articles from the sides is relatively small, and, further, the insides of the sheaths are susceptible to contamination.
Further, when the sheath reaches the store position, arresting takes place as the first lips laterally strike the second lips, in other words through a very small contact, which can easily lead to wear, damage and may even cause one or more lips to be torn loose. As a consequence, not only does the arrest in the store position become less accurate, but he coupling between two sheaths is also affected, because the lips, together with the coupling part, are also involved therein.
A first lip on the back face part of a superjacent sheath, extending between the top wall part and the back face part of a subjacent sheath, is covered within the subjacent sheath by the coupling part of the superjacent sheath. Thus, this coupling part of the superjacent sheath is part of the internal surface of the subjacent sheath. This means that when the superjacent sheath is moved relatively to the subjacent sheath, at least a portion of the internal surface of the subjacent sheath moves relatively to the article stored in that sheath. The friction or abrasion involved therein may lead to the formation of abrasive particles and hence cause damage o the article stored, particularly if this is an electronic data carrier such as a floppy disk. Moreover, in order to enable movement to the display position, the free lower edge of the coupling part of the superjacent sheath should be spaced from the bottom of the subjacent sheath by a distance at least equal to the desired moving distance. When moved, this free end edge of the coupl
