Abstract

The subject-matter of the invention is a folded package (1) preferably for sheet-like articles which are stacked congruently one above the other and are approximately sector-shaped in contour, for example filter paper inserts (4) for coffee machines or teamakers. The object of the invention is to provide a folded package (1) which can be produced inexpensively, is convenient to open up for removal of all the articles and can also be completely closed again. This is achieved in that the folded package (1) is produced from an integral, essentially square blank of paper or a similar, dimensionally stable, foldable material, which blank is folded in from two mutually opposite corners, extending in the manner of a wrapping around the stack of articles to be packaged. The folding-in takes place in such a way that a pocket (5) which envelopes the stack of articles on all sides is formed on one wrapping side and a lid flap (8) is formed on the opposite side, which lid flap can be fixed in relation to the pocket (5) by means of a reusable closure device (10). The lid flap (8) is stabilised by the connection of individual folding layers (9) in such a way that the lid flap (8) automatically assumes its original shape when closed again. <IMAGE>

Description

The present invention relates to a foldable package for predominantly leaf-like, stacked and horizontally projected cut-out articles, such as filter paper trays, for coffee or tea makers.

For the packaging of the aforementioned types of products, especially filter paper trays for coffee or tea makers, cardboard folded boxes have, until now, mostly been produced. It is also known that this type of product can be packaged in so-called wrinkled films.

The first type of packaging mentioned above is relatively expensive because it is made of cardboard and, moreover, takes up more volume than would be required for the packaging products.

The wrapping of filter paper trays for coffee or tea makers has a disadvantage associated with the fact that the wrapping must be expanded and, after opening the wrapping of this type of wrapping, it is no longer possible to secure the wrapping; in this way, filter paper deposits or similar articles from the already opened wrapping of the film should normally be transferred to another box.

SUMMARY OF THE INVENTION The object of the present invention is to provide a packaging of the type mentioned above which, on the one hand, could be cheaply manufactured and, on the other hand, would have the advantage of being able to open and close many times during use.

According to the invention, this object is solved by the fact that the foldable packaging is made of a solid, mainly square, paper or paLT 3503 B high-performance, shape-retaining and flexible material; this clip is folded, depending on the type of folder, into two stacked stacked, stacked articles, such that a guaranteed cut-out is formed on one side of the folder by merging the corresponding parts of the folder on the side, the cover sealing lining, which completely covers the removable opening and is secured with a re-closing device before removal; in addition, the individual plugs of the lid lining are interconnected to ensure stability of the mold; thus, in order to retrieve individual articles from the recess, the butt joint of the cap may be opened wide enough in the open position, but may then automatically return to the closed position.

This type of foldable wrapper can be made of synthetic material from a relatively cheap paper, such as coated paper.

also made of suitable films of synthetic materials, and virtually seals the packaged articles in such a way that the finished packing has no or practically no voids. For taking individual sheet-shaped articles, such as filter paper trays, the foldable package can be opened wide enough and, when taken, for example, filter paper trays, can be easily closed again, since the lid lining shape prevents uncontrolled lapping of the lid lining . In this way, the user creates a foldable wrapper that retains its shape stability and, at the same time, its protective function when it is consistently sampled.

In the boxes of the invention

The example depicted in the Figures for performing Figures is further illustrated below:

explained in more detail below.

Fig. 1 is a perspective view of the foldable package according to the invention in closed position;

FIG. 2 is a perspective view of the foldable package of FIG. 1 in the open position;

Fig. 3 is an outline of a cutout for making a foldable packaging according to Figs.

Figures 1 and 2 illustrate a foldable package 1 made entirely of a notch 2 according to Fig.3. The cutout 2 is practically square, with the corners 3 of the cutout 2 being slightly cut. The cutout 2 is made of paper, but can also be made of artificially coated paper or similar artificial material, which retains its shape when folded.

The embodiment illustrated shows a collapsible wrapping for receiving filter paper trays 4 for use in coffee or tea makers; this is particularly illustrated in Fig.2.

Accordingly, by longitudinally folding the notch 2 according to FIG. 3, the stitching line of filter paper trays 4 is sewn using two opposite corners 3 of the clip 2 to form a recess 5 on the lower side of the folder which wraps the filter paper trays 4 on all sides and has only one take-up opening 6, for picking up filter paper pads 4. The recess 5 is secured or stabilized by a connection to the overlapping portions 7 of the folder. The overlapping folder portions 7 may be glued to one another or joined to one another by activation in a hot stamping medium.

The side opposite the recess 5 is formed by the corresponding folding of the lid sealing liner 8, in which the individual pleats 9 are interconnected in order to maintain a constant shape of the lid sealing liner. Also in this case, the jointing may be accomplished using glue, hot stamping medium or other jointing techniques.

Stabilizing the shape of the cap joint 8 by engaging the pleats 9 has the effect that the lid joint 8 can be opened to such an extent that it is possible to take the filter paper liners 4, but on the other hand to its closed position. Effective shape stabilization ensures a controlled opening of the 8 lugs of the lid lining during opening and closing; thus, the user does not have to pay particular attention to closing the foldable packaging.

The lid sealing lining 8 is mounted in the closed position of the recess 5 by means of a re-sealing device 10, for example in the form of an adhesive strip.

As shown in Fig. 2, the recess 5 is provided with an attachment or holding point 11, which is outside the scope of the re-sealing device 10 and is glued to the lid sealing liner 8 during the first opening of the foldable packaging. 8 must be opened by resisting the adhesive force of the attachment point 11; this way the user can immediately see that he is opening the foldable package for the first time. Thus, the attachment point 11 simultaneously forms the so-called original closure.

Due to its concept, foldable packaging 1 is inexpensive to manufacture and provides effective protection of the wrapped products until they are completely removed.
