Abstract
The present invention proposes a capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device, the capsule comprising a cup-like body portion, a flange-like rim portion, a delivery wall and a sealing member having—in a radial cross sectional view—at least one protrusion and/or recession.
Claims19
A capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device, the capsule comprising:
- a cup-like body portion,
- a flange-like rim portion positioned at one end of the capsule,
- a delivery wall, and
- a sealing member made from plastic, designed for compensating for eventual irregularities in a matching sealing surface of a beverage production device cooperating with the sealing member of the capsule, and comprising at least two lips distanced from one another in a radial direction, each having a first height and a width such that the first height is at least 1.5 times larger than the width, each protruding from and integrally formed with the flange-like rim portion of the capsule, each extending from the flange-like rim portion in a direction toward an opposite end of the capsule, and at least one of the lips is designed to be compressed from the first height to a second height.
A capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device, the capsule comprising:
- a cup-like body portion,
- a flange-like rim portion positioned at one end of the capsule,
- a delivery wall, and
- a sealing member made from plastic, designed for compensating for eventual irregularities in a matching sealing surface of a beverage production device cooperating with the sealing member of the capsule, and comprising at least two lips distanced from one another in a radial direction, each having a first height and a width such that the first height is at least 1.5 times larger than the width, each protruding from and integrally formed with the flange-like rim portion of the capsule, each extending from the flange-like rim portion in a direction toward an opposite end of the capsule, and at least one of the lips is designed to be compressed from the first height to a second height,
- wherein the lips comprise a first lip, a second lip and a third lip that are concentric, the first and third lips have a greater height than the second lip, the second lip is positioned between the first and third lips in the radial direction, the first and third lips are positioned to not be compressed by a matching sealing surface of a beverage production device, and the second lip is designed to be compressed from the first height to the second height.
A beverage production system, comprising a capsule for containing beverage ingredients, the capsule being designed for insertion in a beverage production device, wherein:
- the capsule comprises a cup-like body portion, a flange-like rim portion positioned at one end of the capsule, a delivery wall and a sealing member made from plastic and comprising at least two lips distanced from one another in a radial direction, each having a first height and a width such that the height is at least 1.5 times larger than the width, each protruding from and integrally formed with the flange-like rim portion of the capsule, each extending from the flange-like rim portion in a direction toward an opposite end of the capsule, and at least one of the lips is designed to be compressed from a first height to a second height;
- and
- a beverage production device designed for receiving the capsule in a brewing chamber, the brewing chamber is defined, at least partially, by a capsule enclosing member having a front surface with irregularities, the front face of the enclosing member cooperating with the sealing member of the capsule, and the sealing member of the capsule is designed for compensating for the irregularities in the front surface of the capsule enclosing member.
