Problems solved by technology

The drawback of this improvement is that after a large number of capsules are used, the fixed seal wears out, so that the quality of the resulting drink deteriorates due to the passage of water through a seal that is no longer fully effective
Also, dirty seals with sticky organic residues are unhygienic and can affect seal and pressure conditions during extraction

Embodiment Construction

[0054] It should be noted that in the following the invention will be explained with reference to a specific design of a capsule, ie a design in which the capsule comprises a cup-shaped base and a closure foil member. However, it will be appreciated that other designs of the capsule are possible, for example a capsule in the form of a lenticular lens in which two substantially matching and opposing walls (eg foils) are sealed at eg an annular edge. A capsule according to the invention generally comprises at least two opposing wall parts (surfaces) interconnected at their respective edges to form a sealed flange-like rim region enclosing a sealed interior.

[0055] This embodiment shows a capsule holder 13 with a relief element 12 for tearing and piercing the foil part 5 closing the cup-shaped base 4 of the capsule 1 . The tearing of the foil member 5 takes place immediately when the pressure inside the capsule exceeds a threshold value. It should be noted that the relief elem...

Abstract

Method for producing a capsule (1) containing beverage ingredients designed for insertion in a beverage production device in which a liquid under pressure enters the capsule in order to interact with the ingredients in the capsule and to drain a beverage from the capsule, wherein the capsule comprises a body (4) with a sealing member attached thereto. The method comprises providing a body (4) with a main cavity, injecting at least one sealing material by injection-moulding onto at least a portion of the external surface of the body (4) to mould a sealing member (8) sealingly attached to the body, filling the cavity with food ingredients and imperviously closing the cavity with a membrane (5) to provide a closed capsule containing the food ingredients.

Description

technical field [0001] The present invention generally relates to capsules for containing beverage ingredients, beverage production systems for use in conjunction with such capsules and methods for manufacturing such capsules. Background technique [0002] The background of the invention is the field of capsules containing beverage ingredients (eg ground coffee, milk powder) or other edible ingredients (eg dehydrated soup). By interacting these ingredients with a liquid, beverages or other foods can be produced. The interaction may be a process such as extraction, brewing / brewing or dissolving. Such capsules are particularly suitable for containing ground coffee for the production of coffee beverages by entering pressurized hot water into the capsule and expelling the coffee beverage from the capsule. [0003] A system and method for obtaining an edible liquid from a substance containing capsule is known eg from EP-A-512470. [0004] The general principle of this extracti...
