Problems solved by technology

However, it has been found that the capsule tends to become spherical at high internal pressure and when the material is sufficiently softened by heat, which in particular then impairs the seal and in the worst case can lead to the capsule getting stuck in the brewing unit

Embodiment Construction

[0046] according to figure 1 with figure 2 The capsule 1 containing the extract, in particular ground coffee, is substantially cuboid with rounded edges. But the extension dimension increases slightly towards the top side, so the capsule has a truncated pyramid shape in a strict mathematical sense. The angle of inclination of the sides in the figure with respect to the vertical to the base 5 is very small, which of course means here the angle of inclination of the sides in the figure with respect to the plane perpendicular to the base and extending through the edge between the base and the corresponding side. The angle of inclination, which is preferably at most 2°, for example only approximately 1°. In addition, the height of the capsule above the base is approximately equal to the length of the side of the base.

[0047] The capsule has a body (or cup) 2 and a lid 3 secured to the body along a surrounding flange 4 . This body forms a capsule bottom 5 and a surrounding s...

Abstract

The invention relates to a portion capsule (1) that is filled with an extraction substance for producing a brewed product, and comprises a main part (2) having a base region (5) and a peripheral lateral wall (6); and a cover (3) secured to said main part (2); the cover (3) being secured to the main part along a peripheral collar (4), this collar (4) being connected to said peripheral lateral wall towards a cover side; said main part (2) having a substantially rectangular cross-section in the region of the collar; the cover (3) forming an outward curvature such that said cover contributes to a capsule volume; and - the collar (4) being at least 1.6 mm wide.

Description

technical field [0001] The present invention relates to the preparation of beverages and the like from capsuled extracts such as ground coffee. In particular, the invention relates to capsules and preparation systems containing extracts. Background technique [0002] Extraction devices for preparing beverages from extract present in portion packs, for example as coffee machines or espresso machines, are known and are still gaining popularity. In many corresponding systems, the portion packs are in the form of capsules in which the extract is enclosed, for example in an airtight manner. For extraction, the capsule is pierced on opposite sides. Infusion (generally hot water) is introduced on the first side. The brewed product is drawn out of the capsule on the second side. Furthermore, depending on the drink and the system to be prepared, a relatively high pressure of eg 5-20 bar must be filled inside the capsule, also lower for filter coffee such as "Americano" or tea. ...
