Description

The present invention relates to a portion pack for producing a A brewed beverage, including one filled with an aroma carrier such as coffee or tea Housing with a circumferential side wall, a base and a cover, the lid being permeable to water at least in some areas and the bottom at least is partially designed as a filter.

Portion packs of the generic type are known per se, see EP 063 1948.

Known portion packs, in which the brewing water is only due gravity is passed through a portion pack are made of different partly water-permeable and partly water-impermeable materials manufactured and have a relatively complex structure.

Portion packs for producing a brewed beverage are also known which the brewing water is led through under pressure through the portion pack becomes. This has the disadvantage that such portion packs only in Connection with appropriately designed brewing devices can be used.

The present invention has for its object a simple and inexpensive portion pack that can be produced and used for gravity brewing create.

This object is achieved in that the side wall and the Bottom in one piece from a filterable plastic fleece or plastic-paper mixture are manufactured in the deep-drawing process and at least the side wall area is waterproof sealed and that the lid is also made of one filterable plastic fleece or plastic-paper mixture manufactured and is compressed in its peripheral edge impermeable to water and that the Lid is tightly connected to the upper edge of the side wall.

Such a portion pack is only made of one starting material - namely a filterable plastic fleece or a plastic-paper mixture and has a relatively simple structure. The portion pack is there from two individual parts, namely one consisting of the side wall and the bottom, pot-like lower part and the lid closing this lower part.

The lower part is made from the filterable plastic fleece or by deep drawing the plastic-paper mixture produced in one operation and in the side wall area compacted in such a way that this side wall area is impermeable to water becomes. At the same time, the side wall area becomes compact due to the compression stabilized so that the entire portion pack is easy to handle.

The lid is also made of a filterable plastic fleece or a Plastic-paper mixture made, in which case only the circumferential Edge area of the lid is compressed in such a way that it is impermeable to water is achieved. After filling the lower part with an aroma carrier the lid is placed on the lower part and connected to it in a sealing manner, what can happen thermally.

The use of a plastic-paper mixture is particularly ecological Considerations advantageous because this material is predominantly renewable Contains raw material (pulp).

Overall, a portion pack according to the invention can be produced very inexpensively and highly practical, since the brewing water leaches out the aroma carrier only passed through the portion pack due to gravity must become.

Special brewing devices for using the portion pack are therefore superfluous.

Further features of the invention are the subject of dependent claims.

An embodiment of the invention is shown in the accompanying drawings and is described in more detail below.

In detail show:

Figure 1
3 shows a section through a lower part of a portion pack according to the invention and through a tool by means of which such a lower part is produced,
Figure 2
2 shows a schematically illustrated size comparison between the starting material for producing the lower part before and after compression in the tool according to FIG. 1,
Figure 3
2 shows a sectional illustration corresponding essentially to FIG. 1 through the lid of a portion pack according to the invention and through a tool for producing this lid,
Figure 4
a section through a full portion pack according to the present invention.

In Figure 1 is a deep drawing tool for manufacturing in a schematic sectional view a lower part 1 of a portion pack 2 for the production of a brewed beverage shown, the deep-drawing tool from a die 3 and a male 4th exists and at least the die 3 is provided with a heater 5.

In this tool, the already mentioned lower part 1 of a portion pack 2 manufactured.

The starting material for the production of the lower part 1 is a filterable plastic fleece 6 with a predetermined material thickness D. Alternatively, can also a plastic-paper mixture can be used.

By deep drawing a corresponding section of material from this plastic fleece 6, the lower part 1 is formed in the tool according to FIG a circumferential side wall 7 and a bottom 8. These two parts 7 and 8 are thus made in one piece and the side wall region of this lower part 1 is compressed during manufacture such that at least the entire side wall area becomes impermeable to water. In the illustrated embodiment also an annular region 8a of the adjoining the side wall 7 Soil 8 deformed accordingly, while the majority of the floor 8 due to the fact that the die with a corresponding recess 9 is provided, is practically not deformed and thus retains its filter properties.

Figure 2 makes it clear that the plastic fleece 6 compresses to a material thickness D1 which is only a fraction of the original material thickness D.

Due to this enormous compression under the application of heat and under the pressure of the patrix 4 the compressed areas (side wall 7 and bottom edge area 8) on the one hand impermeable to water and on the other hand also largely dimensionally stable.

FIG. 3 shows that a cover 10, which is also made of a plastic fleece 6 is produced, manufactured in a die 3a with the aid of a die 4a becomes. In this case, only the peripheral edge region 11 of the cover 10 to Waterproofing densifies while the middle section 12 of the lid 10 through the recess 9a of the die 3a practically undeformed and thus permeable to water remains.

After completion of the lower part 1, this is with an aroma carrier 13, z. B. filled with coffee or tea and then the lower part 1 by the Cover 10 closed. The lid 10 is advantageously on one upper edge of the lower part 1 forming, circumferential flange 14 and is with this circumferential flange 14 is thermally connected and thus the lower part 1 tightly closed.

The practically undeformed area 12 of the lid 10 can now be used for brewing water for the preparation of a brewed beverage to be let into the portion pack 2 and this brewing water soaks both the aroma carrier due to gravity 13 as well as the filterable area of the bottom 8. Since the side wall 7 of the housing consisting of lower part 1 and cover 10 practically impermeable to water brewing water cannot escape in an uncontrolled and undesirable manner, but the brewing water must be completely through the aroma carrier 13 flow.

The portion pack 2 produced as described above is simple and inexpensive to manufacture and highly practical, since none for their use Special facilities are needed.

A polymer plastic fleece is preferred for the production of the portion pack 2 6, as this is particularly suitable for manufacturing under heat and pressure is and also a simple thermal connection between the lower part 12 and cover 10 allows.
