The innovation concerns an index card with a punched out Window to hold a rectangular aluminum address foil with four corners punched out inwards, which are divided into lungs and Transverse direction is larger than the window.

Known index cards of the type relating to the innovation are laminated as double cards, with a template being punched out. The glue is left out at this point, up to the edge of the index card, so that the aluminum address foil can be inserted. The production of such index cards is associated with considerable costs.

The innovation is based on the task of the known Developing and improving index cards around the world, specifically in the direction that the production with significantly lower costs are possible than those of the known index cards. In addition, according to the innovation Index card more resilient than «lie known Be index card. Finally, the aluminum address foil

The innovation is that parallel to two opposite sides of the window at a distance from the Sides One slot each for inserting and locking the corresponding side of the aluminum address foil, whereby this Each with the inner part of its punched-out corners on the receiving slot attachment, and on the two other opposite sides of the window at least one punched-out retaining tongue for clamping on the corresponding side of the aluminum address foil

Advantageously, according to a further suggestion of the innovation, the index card is designed in such a way that the Receiving slots parallel to deaa narrow sides and the retaining tongues are provided on the broad sides of the window.

The features according to the innovation make it possible for the first time an index card with a punched-out window to hold a

to create easily detachable aluminum address foil, which consists of only a single sheet of cardboard. It is no longer necessary to conceal the index card as a double card and

to block out the glue at the point of the window. This ensures that the index card according to the invention Can be produced at much lower cost than well-known laminated index card.

Another major advantage is that the aluminum address foil can be inserted into the Window can be inserted or removed from dlosem, is properly locked and recorded on the index card.

The innovation can be carried out in various ways. An example is shown in the attached drawing shown and that shows:

Figure 1: An index card with inserted Äiu-Ädress foil,

Figure 2: an aluminum address foil,

Figure 3: an index card with a window without an aluminum address foil

The index card Io consists of a single sheet of cardboard. It has a punched out window 11. This serves to accommodate a rectangular aluminum address foil 12. The aluminum address foil 12 is punched inwards at its four corners 12a. The aluminum address foil 12 is larger in the longitudinal and transverse directions than the window 11. It therefore overlaps the window on all four sides.

On two opposite sides 11a of the window, at a distance from each side 11a, there is a receiving slot provided in the Io tab. This is used for plugging in

and locking the corresponding beit-e 12, the aluminum address sheet 12. The receiving slots 13 are spaced apart from one another in such a way that the aluminum address sheet lies flat when inserted, that is to say is not curved. In the inserted state, the inner part of the cut corners 12a abuts the receiving slot ends 13a. This means that the aluminum address foil is already correctly locked in relation to the window. In order to hold the aluminum address foil 12 properly in the area of the pensler 11, at least one punched-out retaining tongue 14 is provided on each of the two other opposite sides 11b of the window 11 to clamp the corresponding side 12 _{O of} the aluminum address foil 12.

It has been found to be particularly advantageous that, according to a further suggestion of the innovation, the receiving slots 13 parallel to the narrow sides 11a and the Holding tongues 14 on the broad sides 11b of the window 11 are provided. In this way it is achieved that the insertion or removal can be carried out in a simple manner on the one hand, and the inserted aluminum address foil on the other is properly locked in the correct position in relation to the window and is held on the index card.
